    This paper describes research on materials of equipment for the second stage reaction in relation with development on a hydrogen manufacturing technology by using the iodine system cycle in the thermo-chemical method. The second stage reaction produces MgO, I{sub 2} and O{sub 2} by decomposition of Mg(IO{sub 3}){sub 2} at 600 to 650 degrees C. Corrosion tests were carried out by using 25Cr-20Ni steel and Ni-50Cr alloy having shown relatively high corrosion resistance in the researches to date, which were added with trace amount of different alloy elements. The tests were performed in gas mixture of I{sub 2}, O{sub 2} and H{sub 2}O at 600 to 700 degrees C for 48 to 192 hours. The average corrosion rate of 25Cr-20Ni steel was reduced by adding Y(0.2%), Ca (0.2%) or Si+Al (1%Si+1%Al), by which relatively uniform corrosion pattern was shown, and the corrosion resistance was improved remarkably. The average corrosion rate of 25Cr-20Ni steel showed a trend of increasing by adding Si and Nb, and non-uniform corrosion like pitting has occurred, revealing that it is not preferable from the aspect of corrosion resistance. The average corrosion rates of the tested materials tended to become somewhat greater under heat insulated condition than under continuously heating condition. Effect of Mg(IO{sub 3}){sub 2} deposition is very small. (NEDO)

    From among researches on hydrogen manufacturing technologies using thermo-chemistry in the Sunshine Project, discussions were given on equipment materials, with the second-stage reaction in the iodine system cycle as the object. This paper describes achievements in fiscal 1979. The reaction produces MgO, I{sub 2} and O{sub 2} from Mg(IO{sub 3}){sub 2}. Corrosion tests were performed by using test pieces made of Ni alloy, iron-Ni-Cr alloy, Ti alloy, Zr alloy, Nb and Ta. These materials are thought to have excellent corrosion resistance in high temperature gaseous phase composed of iodine, oxygen and water. Corrosion tests were carried out also by using sheet formed test pieces of 24 kinds of alloys and six kinds of commercially available non-ferrous metallic materials in different temperatures and atmospheres, mainly the iodine plus oxygen plus H{sub 2}O mixed gas atmosphere at 600 degrees C. The corrosion resistance of the tested materials can be divided into three ranks. Materials having relatively good resistance were Ni-50Cr alloy and Co group alloy. Materials having good corrosion resistance are very little affected by water content. The higher the temperature, the more the metal corrosivity has increased. Preliminary discussions were given on pipe formability in materials having good corrosion resistance as the equipment piping materials. Their mechanical properties were also tested. This paper also describes corrosion resistance tests under heat transferring condition by using pipe-formed test pieces. (NEDO)

    Iodine-alkaline earth metal (Mg, Ca) cycles are discovered, and the one with Mg is found excellent. The reaction consists of four stages, that is, Stage (1) where 1/5Mg(IO{sub 3}){sub 2}+MgI{sub 2}(aq) is obtained from 6/5MgO+6/5I{sub 2}, Stage (2) where 1/5MgO+1/5I{sub 2}+1/2O{sub 2} is obtained from 1/5Mg(IO{sub 3}){sub 2}, Stage (3) where MgO+2HI is obtained from MgI{sub 2}+H{sub 2}O, and Stage (4) where H{sub 2}+I{sub 2} is obtained from 2HI. Since there is much iodine and water at Stage (1), MgO thrice MgI{sub 2} in mol is added for reforming and concentration. At Stage (4), where the decomposition rate is as low as 17-27% with the equilibrium dissociation reaction proceeding at 300-700 degrees C, hydrogen is selectively separated by permeation through a porous diaphragm for the acceleration of the reaction. As for materials for the device, they are narrowed down to high-priced ones, that is, Ta and Nb for Stage (1), Ni-50Cr for Stage (2), and Mo etc. for Stages (3) and (4). Under the circumstances, a study is started for the development of a chemical vapor plating process which is high in corrosion resistance. Other cycles such as sulfur-based cycles and hybrid cycles are also investigated. (NEDO)

    A CWM manufacturing technology was developed by means of upgrading low rank coals. Even though some low rank coals have such advantages as low ash, low sulfur and high volatile matter content, many of them are merely used on a small scale in areas near the mine-mouths because of high moisture content, low calorification and high ignitability. Therefore, discussions were given on a coal fuel manufacturing technology by which coal will be irreversibly dehydrated with as much volatile matters as possible remaining in the coal, and the coal is made high-concentration CWM, thus the coal can be safely transported and stored. The technology uses a method to treat coal with hot water under high pressure and dry it with hot water. The method performs not only removal of water, but also irreversible dehydration without losing volatile matters by decomposing hydrophilic groups on surface and blocking micro pores with volatile matters in the coal (wax and tar). The upgrading effect was verified by processing coals in a pilot plant, which derived greater calorification and higher concentration CWM than with the conventional processes. A CWM combustion test proved lower NOx, lower SOx and higher combustion rate than for bituminous coal. The ash content was also found lower. This process suits a Texaco-type gasification furnace. For a production scale of three million tons a year, the production cost is lower by 2 yen per 10 {sup 3} kcal than for heavy oil with the same sulfur content. 11 figs., 15 tabs.

    In utilizing coal for high-efficiency direct power generation using fuel cells, it is necessary that coal be fed into the fuel cells after having been made into ash-free gaseous fuel. Research and development works are being carried out with an objective to develop a coal gasification furnace most suitable for fuel cells and establish a system to refine coal up to the one that can be fed into fuel cells. Fiscal 1995 has conducted investigations on coal gasification technologies, air separation technologies, and gas refining technologies as the important element technologies, and a trial design on integrated coal gasification fuel cell (IGFC) systems. This paper reports from among the above items the result of the trial design on an IGFC system using molten carbonate fuel cells. The paper describes system comparison on paths of produced gases and anode waste gas, comparison on refining processes using a wet system and a dry system, and parameter studies on oxygen concentration in gasifying agents. It was made clear that the suitable furnace is an oxygen blown coal gasification furnace, and the power generation efficiency at the system terminal can be higher than 53%. 11 figs., 6 tabs.

    This report covers part of the efforts to develop new hydrogen production technologies. Out of many processes involving Cu-halogen and alkali carbonate-iodine systems proposed as novel thermochemical processes, after they are compared with each other, a process of a sodium carbonate-iodine system with nickel in between is chosen. The chosen process is deemed to be the most excellent among the processes disclosed up to fiscal 1975. A feasibility study is conducted for the chosen process from the viewpoint of reaction rate, separation of reactive substances from each other, method for reaction manipulation, materials for device constitution, and thermal efficiency. As for the measurement of reaction rate for each unit reaction, basic reaction data are determined centering about the nickel iodide decomposition reaction and the sodium iodide carbonation reaction, and then reaction conditions which are roughly satisfying are obtained. A larger reaction unit is built in which the amounts of substances that come into reaction are approximately 10 times larger than those in the ones used in basic experiments. The progress of reactions is observed in the reaction unit, with the size enlarged in preparation for future construction of still larger reaction units. Methods for selectively isolating hydrogen out of gases ensuing from the decomposition are evaluated from the viewpoint of energy efficiency. In the selection of a reaction manipulation method, a single unit reaction process is advocated, and its thermal efficiency is estimated. (NEDO)

    This paper reports the study results on manufacturing of low-cost Si substrates by continuous casting method in fiscal 1994. (1) On manufacturing of ingots of 16 piece size, the ingot of nearly 170kg was manufactured by batch process using the Si melt injection unit prepared in last year. (2) On oxygen and carbon contents in wafers, the contents were measured by FT-IR after slicing of the ingot. As a result, the oxygen and carbon contents could be successfully reduced to the targets of 10ppma and 5ppma or less, respectively. (3) The resistivity distribution of the ingot ranged over the target of 1-2ohm-cm. (4) Cells of 100 {times} 100mm{sup 2} wide and 350{mu}m thick were verified by in-house evaluation process. Although lower cell conversion efficiency was found at the center top of the ingot, a vertical efficiency stability was nearly sufficient as a whole.

    R and D on the production technology of hydrogen by biotechnology is one of the effective projects for worldwide energy supply technology and global environment protection technology in the 21st century. The research trend of various institutions promoting R and D on production technology of biohydrogen in the U.S.A. and other countries was surveyed together with the possibility of international cooperation. The production technology of biohydrogen is being watched over the world. Various researches are in promotion corresponding to environmental conditions as follows: search of not only photosynthetic bacteria but also such bacteria with hydrogen productivity as algae and anaerobic bacteria, and the gene engineering study for improving the hydrogen productivity of target microorganisms. All the institutions visited for this survey have great expectations in wide cooperative study in the future. On the possibility of international cooperation on the production technology of biohydrogen, the further precise survey should be promoted for developing more effective technologies based on the previous survey results. 156 refs., 10 tabs.

    For the purpose of developing a new hydrogen production technology, a feasibility study was made of the copper-halogen system and alkali carbonate-iodine system processes presented as a new thermochemical process from viewpoints of the progress of reaction, side reaction, reaction yield, thermal efficiency, etc. The study went forward smoothly, has achieved the target in the early stage, and has been finished. In the study of optimal conditions of the process, the progress of each unit reaction was experimentally confirmed. By measuring the reaction yield, optimal reaction conditions for expediting the reaction were found out. As a result, it was found that the proposed processes proposed both advance rather easily, and was thought that those are worthy of making further engineering study. In the study of improvement and optimization of the process, since some altered processes are considered for the processes presented, an investigational study was made on a method to calculate thermal efficiency which is one of the standards for the process evaluation, and thermal efficiencies in various processes were trially calculated, based on the calculating method. As a result, it was thought that this process is equal to other processes. (NEDO)

    The trend of technology development, problems harbored therein, trend of the market, and the like were investigated for supporting the development of technologies for the mass production and commercialization of solar-grade silicon materials. Concerning the future of production enhancement and cost reduction in the manufacture of polycrystalline silicon solar cells, studies were made from the technological viewpoint. The results are shown below. It is estimated that approximately 4,500 tons of material silicon will be necessary in 2005 and 6,500-10,700 tons in 2010. Since the melting purification method of NEDO (New Energy and Industrial Technology Development Organization) now under development step by step toward commercialization as well as the conventional source will provide the necessary amount of material silicon, it is inferred that the development of solar cells will go on without any restraint originating in the semiconductor industry. With the commercialization of the technologies so far developed and the development/commercialization of the fast-acting high-performance solar cell technology, probabilities are high that the polycrystalline silicon solar cell manufacturing cost in 2010 will be as low as to be on the 100 yen/W (93-118 yen/W) level which is the level now held up as the goal.

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a semiconductor equipment field, viewing until 5-10 years after. For the future semiconductor industry, the favorable cycling of creation of new demands through performance improvement, and further technology innovation through market expansion is essential absolutely. Since technology development is followed by investment, not only the performance of each equipment but also the higher productivity and cost balance of the whole factory are essential. Self-intelligent function and networking are thus necessary for the equipment. As measures for environment preservation and energy saving, such innovative technologies are required as recycling, reuse, reaction process improvement and alternative technology. Because of diverse final products and a short life time of products, a large-scale collective investment is becoming difficult. A mini-line sequential investment production system according to demand scales is under investigation. Some issues such as micro-technology, realization of 300mm wafer, modularization, CIM, reliability and standardization are also described. (NEDO)

    As a plan to develop technologies to manufacture materials and substrates for thin film solar cells, it is intended to reduce defect density, enhance film forming speed, largely improve the photo-electric conversion efficiency and increase manufacturing productivity. These goals will be realized by establishing methods to control defect density, crystal particle diameters and crystallization rate in silicon crystal systems. A technology to form micro-crystal silicon-based thin films will be developed, that have superior photo-stability, and are capable of realizing low cost and mass production. Discussions will be given on a high-density plasma control technology, a fundamental property evaluation technology for micro crystal silicon thin films, and a device design simulation technology. A technology will be developed to form amorphous silicon layer on a stainless steel substrate by using the plasma CVD process. At the same time, discussions will be given on optical annealing and thermal annealing as reformation methods. Fiscal 1997 has surveyed component technologies to identify and analyze quickly and accurately the technical trends inside and outside the country, and to mass produce thin film solar cells. The Material and Substrate System Technology Subcommittee (silicon crystals) was held to deliberate the four-year development program and its progress. (NEDO)

    With an objective to assist research and development to put thin film solar cells for power use into practical use and a research to put thin film solar cell manufacturing technologies into practical use, survey and research have been performed on trends in the technologies inside and outside the country. Characteristic points in thin film solar cells during the current fiscal year include: expansion of production scale of amorphous silicon solar cells, rapid progress in poly-crystalline silicon thin film solar cell technologies, and enhancement of performance in large-area modules in the a-Si, CIGS, and CdTe systems. In the trends in research and development of amorphous systems, expectation is heightening on elucidation of optical deterioration phenomena, and establishment of suppression technologies thereof. Although the highest efficiency was not renewed in thin film solar cells of small areas, progress was seen in the post-stabilization efficiency in large-area modules. A thin film solar cell manufacturing plant having an annual production capacity of 20 MW was put into operation in October in Japan. Micro (poly) crystalline silicon based solar cells have high possibility of being compatible in cost reduction and performance improvement, and energetic researches are being carried out on them in recent years as the most promising candidate of the next generation solar cells.

    This paper describes a summary design of an iodine cycle experimenting equipment as one of the achievements in fiscal 1978 on research of hydrogen manufacturing technologies using the thermo-chemical method. The object of the equipment is a reaction to derive Mg(IO{sub 3}){sub 2} and MgI{sub 2} from MgO being the first reaction of the cycle, and iodine. The by-product (Q-phase) is produced according to composition of the aqueous reaction solution. The occurring reaction and composition of the produced materials vary depending on which contact system the reactor type uses, countercurrent flow or concurrent flow. Discussions were given on both types. Hydrogen generation rate of 1 Nm{sup 3}/hr was assumed as the equipment size to derive material balance and heat balance. Furthermore, types considered applicable were selected from different types of the solid-liquid reaction equipment, and summary design and calculation were performed. Process simulation provided a prospect of achieving thermal efficiency that can compete with the electrolytic process. As a study on materials for a magnesium iodate pyrolytic equipment as the second reaction, corrosion tests were carried out in a gas mixture composed of iodine, oxygen and steam. Using 26 kinds of metallic materials as the objects, the tests were executed at 100 and 300 degrees C for 100 hours. Long-term durability tests were also performed on materials judged to have good corrosion resistance. (NEDO)

    In relation to the R and D of the hydrogen production technology by the thermochemical method, the paper summed up the results of the research conducted in FY 1974. The items for study are as follows. (1) Basic model making for process simulator. (2) Type of facility on the assumption of pilot plant size, and rough selection of equipment structural materials. (3) Extraction of engineering study subjects and working-out of study plans. In (1), the basic model of simulator was established, case studies of various Fe-Cl cycles were made, and a calculation method for the balance of the whole process was established. In (2), it was concluded that in the normal pressure reaction experiment, the oxygen emits extremely little in amount in Mark 9 No. 2 reaction, and therefore, it is very doubtful whether the closed cycle will be completed using this reaction. It was also found out that No. 3 reaction is low in reaction completion degree and it is the problem in point of thermal economy. Accordingly, possibilities of reaction were reviewed, and 6 cycles were found as Fe-Cl cycle. For these reaction cycles, a process flow sheet was made. Comparative studies among processes were conducted, and the cycle structural elementary reaction in Fe-Cl process was specified. (NEDO)

    The goals at present are to clarify conditions for the realization of the water electrolysis process relative to various primary energy sources and to experimentally construct a small practical electrobath to operate at high temperature and high pressure for the attainment of high economic efficiency. Efforts in this fiscal year are mentioned below. Surveys and studies are conducted about hydrogen production by water electrolysis and about achievements in the past and problems at present concerning hydrogen production by water electrolysis in Japan and overseas. The expected role of water electrolysis in various primary energy sources is also studied and evaluated. For a high-temperature high-pressure water electrolysis bath conceptual design (small test plant, bathing temperature 120 degrees C, pressure 20atm, hydrogen production rate 2Nm{sup 3}/h), studies are conducted about a constant-load type high-temperature high-pressure (bipolar) diaphragm-assisted water electrolysis bath and a variable-load type high-temperature high-pressure diaphragm-assisted water electrolysis bath.

    The research and development centers on the details of the Fe-Cu-Cl-based cycle. The items studied in this connection are (1) the development of a process simulator, (2) an experimental study of the Fe-Cu-Cl-based cycle, and (3) the recapitulation of the Fe-Cl-based cycle. The outcome of the comparison of Fe-Cl-based cycles widely conducted in the past enables a conclusion that the Fe-Cu-Cl-based cycle is at present is the most practical, technologically as well as in the way of thermal efficiency. The achievement on the first reaction (hydrolysis of ferrous chloride) of fiscal 1975, and then what is reported in literature on the fifth reaction (reverse Deacon process), are incorporated into the experiment of fiscal 1976, and this completes the acquisition of basic data necessary to develop the Fe-Cu-Cl-based cycle into an application process. Using optimum conditions chosen out of these basic data, a flowchart is compiled and the details of the process are calculated. As the result, a thermal efficiency of 30-33% is obtained, and the figures are deemed to indicate that the thermochemical method is sufficiently superior to the electrolytic method. (NEDO)

    With the background that making the incineration residue of municipal waste nonpollutant or recycling the residue have been an urgent problem, Japan's first incineration ash recycle experiment pilot plant was built in the Nanbu Waste Incineration Plant of Funabashi City in 1993. In this paper, the outline of the one-year plant operation has been introduced. This plant consists of an artificial aggregate production line and a permeable block production line. In the former line, the incineration or fly ash is combined with plasticizer (clay) and then added by moisture. After the mixed material is extruded and pelletized, the pellets are sintered in a rotary kiln to be artificial aggregate. The sintering temperature is 1200[degree]C at a maximum and throughput of the raw materials is 130 kg/h. The evaporated and dispersed salt or low boiling point heavy metals are mixed in the flue gas and collected with bug filters. To produce the permeable block, the following processes are executed: the artificial aggregate is crushed and combined with powdered glass, a binder. The resulting material, after press-molded, is sintered at the temperature of up to 1050[degree]C. The test results showed that the products and plant waste represent satisfactorily acceptable level. 9 figs., 5 tabs.

    With an objective to develop a mass production technology to manufacture silicon raw materials for solar cells, and assist its practical application, surveys and analyses were performed on trends in development of the related technologies, the problems therein , market trends and industrial trends thereof. This paper summarizes the achievements in fiscal 1998. The worldwide production amount of solar cells in 1998 is estimated to have achieved 150 MW, and the silicon consumption reached the level of 2,300 tons. In spite of the economic recession environment, there was no change in the expansion trend. In developing an SOG-Si mass production and manufacturing technology, construction of pilot plants for each process has been completed, and entered into the operation research phase. In developing a technology to manufacture high quality poly-crystalline silicon substrates, fabrication has been completed on the on-line ingot cutting equipment and the plasma heating equipment, and the stage is now in operation research of continuous electromagnetic casting process. The conversion efficiency of the poly-crystalline silicon solar cells is 14 to 16% at the mass production level, whose enhancement requires indispensably the improvement in quality of the substrate. Discussions are required on the ingot manufacturing conditions in coordination with improvement in the cell manufacturing technology. (NEDO)

    This paper describes the achievement in fiscal 1997 of analyzing practical application of a technology to manufacture solar cell silicon raw materials. Silicon consumption for solar cells in fiscal 1997 has increased to 2000-ton level, and the supply has been very tight. For drastic improvement in the demand and supply situation, development of SOG-Si manufacturing technology and its early practical application are desired. The development of the NEDO mass-production technology using melting and refining has completed constructing the process facilities in fiscal 1998, and will enter the stage of operational research. However, insufficiency in the basic data about behavior of impurities is inhibiting the development. In the substrate manufacturing technology, discussions have shown progress on use of diversifying silicons outside the standard by using the electromagnetic casting process. For slicing and processing the substrates, development of a high-performance slicing equipment and automatic rough rinsing machine is under way. Properties required on silicon raw materials vary considerably widely because of difference in cell making systems and conditions, which is attributable to unknown impurity behavior. When 1GW production is assumed, the cell module manufacturing cost is calculated as 137 yen/W, for which low-cost mass production for its realization, slicing productivity enhancement, and cost reduction are required. The paper also describes site surveys in overseas countries. (NEDO)

    The present state and trend are surveyed of organic ferroelectric thin films, new carbon materials, fullerene compounds, and thermophotovoltaic (TPV) power. In the study of organic ferroelectric thin-film solar cells, the effort still remains at the basic stage, with the conversion rate as low as 3% in Europe and 2% in Japan. The progress of basic studies, however, is worth attention. It is deemed that 15% is the photoconversion rate to be currently expected from new carbon material solar cells. Fullerene compounds include some semiconductors whose bandgap values may be controlled across a 0.75-1.95eV range, and they may find their place in thin-film solar cells. However, their physical properties are not fully known, and their development into devices such as solar cells is scarcely reported. The research and development of TPV in the U.S. is led by NASA (National Aeronautics and Space Administration) and NREL (National Renewable Energy Laboratory), with their efforts concentrated on the development of portable power sources utilizing combustion heat. In Europe, TPV application to small-scale residential cogeneration systems is under study. (NEDO)

    Attention is paid to behavior at the molecular level with reference taken to the photosynthetic mechanism, and a behavioral mechanism is proposed, which incorporates, in place of the conventional band model, a concept of a molecular structure based on electron transfer, excitation energy transfer, and reactions of oxidation and reduction. Discussion is then made on elements of technology development for the embodiment of high-efficiency organic ferroelectric thin-film solar cells. The elements taken up include the feasibility of organic ferroelectric thin-film cells, photoelctric conversion systems of plants and photosynthetic bacteria, solar cells using donor-acceptor type dyes, organic thin-film solar cells using conductive polymers, and efficient photoexcitation of organic dyes. Fullerene compounds are semiconductive and their band gaps may be controlled to stay within the range of 0.75-1.9eV, and this justifies a hope that they will serve as solar cells. As for TPV (thermophotovoltaic) conversion, it is under development mainly at NASA (National Aeronautics and Space Administration) as a transportable power source based on heat of combustion. Efforts are also being exerted since 1990 in five European countries to develop TPV systems for small-scale cogeneration. (NEDO)

    For the preparation of a proposition concerning future research and development, surveys and studies were conducted centering about efficiency enhancement and cost reduction for the next generation ultrahigh-efficiency solar cell system. For improving the efficiency of the crystalline compound solar cell, studies were made about the prospects of the embodiment of a 3-junction and 4-junction types and of an increase in conversion efficiency expected to realize thanks to their light condensation behavior. It was inferred that anticipation of 29-47% conversion efficiency in 1 to 4-joint cells was theoretically acceptable. Four-joint structure cell fabrication would be a challenging task but would bring about an conversion efficiency of approximately 47% thanks to enhanced light condensation capability. As for cost reduction through the use of light condensation technology, surveys of overseas trends showed that the condensation-enhanced photovoltaic power system was characteristically fit for lower-price production. As for condensation and tracking systems, studies were made about cost calculation models of organizations involved in the United States and Europe, and then it was found that cost reduction in the optical system for condensation and in the tracking mechanism would be mandatory for the achievement of 75 yen/W.

    This review article focuses on the utilization of several catalysts during coal pyrolysis and gasification. In situ or off line catalytic upgrading of volatile matters during pyrolysis of low rank coals is carried out in pressurized H2 with different reactors to produce BTX (benzene, toluene and xylene). When NiSO4 and Ni(OH)2 are used in the hydropyrolysis of Australian brown coal using an entrained bed reactor with two separated reaction zones, BTX yield reaches 18-23%. MS-13X zeolite and USY zeolite mixed with Al2O3 are effective for producing BTX with powder-particle fluidized bed and two-stage reactors, respectively. Catalytic gasification is described from a standpoint of direct production of SNG(CH4) from coal and steam. When K2CO3 and Ni are compared for this purpose, Ni catalyst is more suitable at low temperatures of 500-600degC, where CH4 formation is thermodynamically favorable. Fe and Ca catalysts can successfully be prepared from inexpensive raw materials and are rather active for steam gasification at {>=}700degC. The use of upgrading and gasification catalysts is discussed in terms of preparation, performance, life and recovery. 27 refs., 6 figs., 2 tabs.

At the end of fiscal 1974, a test equipment was completed in Yubari for the development of gasification process with a coal processing capacity of 5 t/day, operating the gasification furnace for a total of 1,506 hours and gasifying Pacific coal for a total of 185 tons. The gasification reaction conditions were varied within the range of 0.3-1.5 mm coal grain size, 850-1,050 degrees C temperature, and normal to 8 atmospheric pressure, with a continuous test conducted for 48-96 hours, and with basic operation data obtained capable of producing gas having 1,200-1,400 kcal/Nm{sup 3} calories. In addition, through feasibility study, research and investigation were carried out for technologies relating to the practicability of a gasification power generation plant in 30 MW and 500 MW class. Implemented this year were studies for grasping various operating conditions by the 5 t/day gasification equipment, manufacture of a 40 t/day gasification equipment, and foundation work for construction in the Yubari test site.

    Research and development has been performed with an objective to reduce discharge of dioxins in aluminum product manufacturing processes. With regard to the quantity of chlorine used in aluminum molten metal refining process, the refining tests using 100% chlorine gas and the mixed gas (nitrogen gas mixed at 80%) revealed that either gas has approximately the same degassing performance, and the use of the mixed gas can reduce the amount of chlorine used. Dioxin concentrations in the gas discharged from the refining process were measured under the refining condition using less amount of chlorine. As a result, it was verified that, in the case of using 20% chlorine gas plus 80% nitrogen gas, the concentrations of dioxins decrease to about l/6, or 0.6 ng-TEQ/N{sup 3}. The studies on suppressing the discharge of dioxins from the facility to wash chlorine treatment exhaust gas discovered that dioxin concentration in the scrubber circulating solution can be suppressed to 1/10 or less by means of gravity precipitation and separation of the suspended liquid. It was also made clear that pH should preferably be controlled to 10.5 to separate suspended substances from the precipitated solution. (NEDO)

    The research involves tests and studies conducted for the evaluation of corrosion resistance of various metallic materials in molten iodine and for the selection of materials to stay usable under iodine-handling conditions. In fiscal 1982, an iodine transportation system is studied, and corrosion tests are conducted for panels of carbon steels, various stainless steels, titanium, niobium, tantalum, etc., of the grade available in the market, under the conditions where the temperature is 113-170 degrees C, I{sub 2} contains 0-10wt% H{sub 2}O, and the gas phase is of N{sub 2}+O{sub 2}. It is made clear as the result that the effect of water present in I{sub 2} is fairly grave while the influence is but a little of the intensity of temperature and the amount of O{sub 2} gas on the corrosion rates of the respective materials, that materials other than niobium and tantalum are not usable as corrosion resistant materials, etc. In a real device, it is recommended that composite materials be used in the form of a liner or the like because both niobium and tantalum are high-cost materials and therefore create economic disadvantages if employed for the construction of pipes, heat exchangers, etc. (NEDO)

    The electrolysis of water is a hydrogen production technology known since early days. But the efficiency of a commercial electrolytic bath is found at 60-70%, which is too low to prepare for future energy systems. A high-temperature high-pressure water electrolysis process is being studied for improving on the efficiency. For the realization of energy efficiency of 90% or higher, the conventional operating conditions of 90 degrees C or lower, 20A/dm{sup 2}, and 1.8-2.0V bath operating voltage will be improved to be higher than 120 degrees C, 20kg/cm{sup 2}, and 40A/dm{sup 2}, and the electrodes will be modified to work down at 1.65V. The tasks to discharge involve the materials (of diaphragms etc.) for constituting electrolytic baths, electrode catalysts, and electrode shapes. Tests are under way using a test plant capable of producing hydrogen at a rate of 4m{sup 3}/hr. In the analysis of water in a solid polymeric electrolyte, a combination of a cation exchange membrane and a catalytic electrode directly junctioned to the membrane operates as a unit cell. Development is under way with a view to realizing a bath operating voltage of 1.65V or lower at 100A/dm{sup 2}. Since this process still wants much basic research and the materials for bath construction for the process are expensive, further development endeavors will have to be exerted. (NEDO)

    Collected in this report are the results of efforts of the Government Industrial Research Institute, Osaka, in the 7-year period that began in fiscal 1974. The Institute, after looking for basic reactions in thermochemical cycles which are promising, has come to propose a new cycle in which iron and bromine are the reactants. In the research, the Fe-Br reaction is divided into a hydrogen generating loop and an oxygen generating loop, both to be developed into devices. Problems in developing them into a cycle are isolated, and solved. In the hydrogen generating loop, the use of a molten salt is contrived for the prevention of reduction in the reactivity of the Fe{sub 3}O{sub 4} to be generated, and now it is expected that the problem will be solved. No problem is detected in the oxygen generating loop. The process is now accepted as a superb one. As for the materials for the Fe-Br-based cycle apparatus, important tasks have to be undertaken since existing materials cannot be used as is. Besides, thermal efficiency etc. are estimated for a new As-Br-based hybrid cycle and the Fe-Br-based cycle. (NEDO)

As to the application to Ga-As integrated circuits, a guide was acquired for the accumulation speed over 40nm/min. The 5% thickness distribution of inner film of 4-inch wafer, refractive index distribution of 1% or less, and 2D electron gas concentration change of 1.5% could be realized. The experimental device for commercialization was designed and manufactured. Concerning the application to ferroelectric integrated circuits, the accumulation temperature condition was refined as 200 degrees C or less, which resulted in succeeding in forming Si{sub 3}N{sub 4} film at low temperature of 120 degrees C (accumulation speed: 20nm/min.) Relating to the application to Si integrated circuits, a machine to cope with 8 inches was developed. The 6-inch film thickness distribution of 5% and the refractive index distribution of 1% were realized. In regard to the leak current, extreme-thin film was superior to thermal oxidation film. About the application to the formation of high-quality thermal insulation thin films for low temperature polycrystal Si thin film transistor use, poly-Si films with a Hall effect mobility of approximately 10cm{sup 2}/Vs which is relatively high could be formed.

    As to the development of coal use hydrogen production technology, the paper studied the reactivity of char and ignition characteristics of various coals in the use of electric furnace and the participation in pilot plant test and the improvement, and the FY 1993 results were reported. In the study of reactivity of char, it was found that the reactivity was the same, regardless of the equipment and kind of raw coal, if considered of the ratio of the total oxygen amount (the char-containing oxygen amount added to the oxygen supply amount) to the carbon supply amount in char. In the test on ignition characteristics of overseas coals, the same characteristics as those of the Taiheiyo coal conventionally tested were obtained and it was found that it was good to use the same method for start-up of gasifier as conventionally used. In the pilot plant test in the previous year, slag and ash stuck to the outlet of the gasification part and heat recovery part and developed, which hindered the continued operation. To improve it, the following were carried out: model study, study of ash sintering, study using the synthetic test equipment, analysis of the deposit in gasifier, etc. Based on these results, the plant was improved, and the continued operation of 1,149 hours was stably achieved in RUN8.

    This paper describes the formation of fluoride layer on the surface of hydriding alloys. The fluoride formation reaction consists of a reduction removal process of surface oxide and a fluorination process. Specific surface area of alloy grains can be increased by the hydrogenation reaction in the surface layer accompanied with the removal of surface oxide, which results in easier permeation of molecular hydrogen into fluoride layer. During the fluorination process, a large amount of Ni in the alloy components is eluted, which results in the reduction of Ni distribution immediately under the fluoride layer in the alloy. Consequently, collector sites near the surface are reduced, and conductivity among alloy grains is degraded. To enhance the hydrogen collector sites, specific surface area of alloy grains can be increased by controlling the pH value of fluorination treatment solution in a given range. Moreover, performance of fluoride layer can be advanced by electrochemically dispersing metal Ni in the fluoride layer using Ni complex ion mixed in the treatment solution. 2 refs., 3 figs.

    Cost reduction for the above-named solar cells is the aim of this effort. On the basis of the results of past studies, a technology is established of fabricating a thin CdS film by subjecting a CdS film to organometal pyrolysis, and this brings about a decrease in photoabsorption loss in the range of waves shorter than 500nm and a decrease in in-film reflection loss for an increase in short-circuit current density. A proximity sublimation method is used for CdTe film fabrication, which improves on film quality and film adhesion. These efforts result in the achievement of a conversion efficiency of 16.0% which is the highest in the world. Studies are promoted in a process nearer to the ultimate form, and a 30cm times 60cm large CdTe solar cell is fabricated on the basis of a patterning technique, and the product attains a conversion efficiency of 9.8%. In fiscal 1998, studies center about the establishment of a film fabrication process for a medium-are substrate and about the enhancement of its conversion efficiency, and facilities capable of dealing with large-area substrates are introduced and operated. In a typical achievement, a CdTe solar cell is experimentally fabricated in a process which is wholly under normal pressure, and the product with an aperture area of 1376cm{sup 2} exhibits a conversion efficiency of 10.5% according to JQA (Japan Quality Assurance Organization).

Development will be also made on a low-cost process technology. This paper describes the achievements attained during fiscal 1997. Quality improvement has been realized by using a high RF power hydrogen dilution process on a-Si films for front cells of lamination type cells. Four times faster film forming speed was obtained even by using the VHF plasma CVD process, with film quality equivalent to those made by using the conventional RF process maintained. By optimizing the light enclosing construction, the short circuit current was enhanced by over 20%. Discussions were given on forming homogenous a-Si films by optimizing the conditions for forming films on large-area substrates, which resulted in forming film of 30 cm times 40 cm size with good homogeneity at a film forming speed three times faster than the conventional speed. A surface electrode was formed successfully with good uniformity on a substrate with a size of 60 cm times 90 cm. Productivity greater by over three times the conventional productivity was achieved in patterning of transparent electrodes by using high-output laser. Simultaneous and collective patterning and very small and long size collective patterning were realized in a-Si film selection patterning by using the plasma CVD process. (NEDO)

    A microcrystalline Si thin film is used to form the i-layer of a narrow gap a-Si based thin film solar cell. Since a microcrystalline p-layer is to act as the seeding crystal layer for the microcrystalline i-layer, it has to be very high in crystallinity and therefore is produced under high hydrogen dilution conditions. In this process, a problem arises of the darkening of the underlying transparent SnO{sub 2} electrode. Since this is due to chemical reaction on the SnO{sub 2} surface layer, blackening is prevented by shortening the film fabrication time, and then an excellently microcrystalline p-layer is obtained. Furthermore, by inserting a microcrystalline i-film buffer layer of low fabrication rate into the p/i boundary, plasma damage on the microcrystalline p-layer is inhibited for the fabrication of a microcrystalline i-layer high in crystallinity at high film fabrication rates. A high Voc is then obtained even when the microcrystalline p-layer is very thin. If the hydrogen dilution rate is too low when the i-layer film fabrication rate is high, the initially fabricated layer turns out to be thick to the detriment of film performance. On the other hand, the p-layer or the buffer layer will be etched when the hydrogen dilution rate is too high. The problem is solved by continuously varying the hydrogen dilution rate from high to low during i-layer fabrication. (NEDO)

    The project aims to enhance the stability of amorphous solar cells. For elevating TCO (transparent conductive oxide) substrate transmittance to an ultrahigh level and for obtaining amorphous layers less to suffer photodegradation, efforts were made to develop substrate materials stable upon exposure to plasma and low in defect density. In the study of TCO, a high-transmittance glass substrate was employed and TCO was made thinner, and the specimen achieved transmittance of 91.3% or 6.3% over that of the conventional type. In the study of low reflection films, it was found that their transmittance came to be stable and remain so after 150 days after a weatherproof test. In the study for stability enhancement, optimization was carried out for a plasma resisting Ga{sub 2}O{sub 3}-added ZnO film for the manufacture of a substrate material capable of properly behaving in a high-speed a-Si film fabrication process. Low-temperature film fabrication was studied to enable low-cost manufacturing, and it was learned that a 4 times 10{sup -4} ohm/cm low-resistance film was obtained by sputtering Ga{sub 2}O{sub 3}-added ZnO where magnetism was intensive at room temperature, that films excellent in crystallinity were obtained by the same method even at low temperatures, and so forth.

    The target is a low-cost CdS/CdTe solar cell of a large area (60cm times 90cm), the establishment of mass-production technologies for the cell, and the enhancement of production efficiency. A thin film formation technology of subjecting CdS film organic metal to pyrolysis is established, which reduces photoabsorption loss in the shortwave domain of wavelength of not longer than 500nm, reduces reflection loss in the film, and improves on short-circuit current density. Improvement is also achieved on CdTe film quality and junction quality by use of a proximity sublimation method in a vacuum, when a conversion rate of 16.0% (1cm{sup 2}) is attained which is the highest in the world. Based on the results of the above-said efforts, a 3.3mm-thick glass substrate is employed for CdTe film to develop into a 30cm times 60cm-large size, with the film thereon uniformly thick over a large area thanks to a normal pressure proximity sublimation method. Studies are made toward a process nearer to the ultimate product and, using the patterning technique, a 30cm times 60cm-large CdTe solar cell is tentatively built realizing a conversion rate of 9.8%.

    These technological developments are intended to develop technologies to manufacture with improved quality the silicon-based thin film solar cells. In order to analyze manufacturing conditions for micro crystal silicon thin films as the narrow-gap amorphous silicon-based films, films were manufactured in the vicinity of borders of amorphous/micro crystal silicon film manufacturing conditions. The present film manufacturing did not present effects of suppressing deterioration of hydrogen diluted light. In order to elucidate the light deterioration mechanism in hydrogenated amorphous silicon films and study the suppression thereof, discussions were given on impurities in the film, including oxygen. By using an ultra high vacuum plasma CVD having a thoroughgoing baking system, an oil-free exhaust mechanism, and a raw material gas refining mechanism, impurities were added to and removed from a reaction vessel, and an ultra-high purity Si:H film was manufactured, which has been removed of impurities from the raw material gas, resulting in reduction of O, C and N standing no comparison. According to the result of a light irradiation experiment on an ultra-high purity film obtained under an accelerated deteriorating condition by using a pulse laser, the model assuming the light induced defect and the pair of impure atoms has been denied.

    An acorn type concentrator is a 2-dimensional system and realizes relatively high magnification power, but it requires a special assembly process for modularization because the cells and the concentration system are quite small. Under the circumstances, studies are conducted on a prism array concentrator (PAC) which will demand a smaller burden for modularization. A PAC system is basically a 1-dimensional concentrator in terms of light collection performance. The cell to be attached to one plane in the longitudinal direction of the long triangular prism is so small as 5mm in width, yet it may be as long as 50-100mm, and the conventional flat plate assembly process may be made use of. A concentration efficiency of 82% and a conversion efficiency of 10.9% were obtained from a minimodule with a light intercepting area of 5cm times 4cm. Furthermore, a conversion efficiency of 19.7-21.4% was obtained when a small 5mm-wide cell applicable to a PAC type concentration was used. Since a prism type concentrator optical system will cost much for its molding and strengthening when it is built of glass, inexpensive EVA (ethylene-vinyl acetate copolymer) was utilized as an adhesive filler.

    The project intends to improve on large-area amorphous silicon solar cell performance and to develop high-throughput manufacturing technologies for a reduction in the cost of modules. A film substrate type amorphous solar cell structure of the serial connection type named SCAF (series-connection through apertures formed on film) is contrived. Under this method, film formation using a stepping roll system newly developed for glass substrates may be applied, and the number of manhours required is allowed to be less than under conventional serial connection forming processes. The new technique is characterized in that serial connections are established via through-holes provided in plastic substrates. Making use of the technology, progress is attained in the development of high-throughput process technology for film substrate type amorphous solar cells and of efficiency enhancement technology. In fiscal 1997, an electron beam unit for plasma generation aiming at the elucidation of reaction processes in plasma was introduced, and technologies based on the equilibrium discharge technique were developed enabling high-speed a-Si film formation without degradation in film quality. The effect of trace boron addition to the tandem cell bottom I layer was investigated, and a stabilization rate of 8.05% was achieved using a 40cm times 80cm large SCAF cell. In fiscal 1998, endeavors were exerted for similar developments. (NEDO)

Synthesis of polymetric materials by use of CO2 is also described. The paper mentions that it is indispensable to design high-function electrode and elucidate the reaction mechanism of electrochemical CO2 reduction for electrochemical and photochemical CO2 reduction measures. Moreover, in case of using solar energy, it is required to study photovoltaic excitation process in semiconductor electrode/ electrolyte solution interface. For production of hydrogen from CO2 by photosynthetic organisms and solar energy, the problem is control of inhibiting effect of oxygen combinedly produced.

    In the R and D of the high temperature coal gasification technology by the entrained bed system which is the core technology of the coal utilization hydrogen production technology, the paper carried out the dismantling study of pilot plant and the summarization of the results. About the summarization of the results, as the results of the HYCOL operation study, there were insufficiencies in expansion of the coal kind used and acquisition of scale-up data, but it was verified that the conceptual design of the HYCOL method was fully applicable to the higher gasification efficiency, higher reliability, adaptability to many kinds of coal and compactness of facilities (low construction cost) which were the final subjects for the realization of commercial plant. This was highly evaluated. Especially, the greatest characteristic of the HYCOL method is the freedom in selection of temperature difference between the upper stage and lower stage, that is, temperatures can be controlled to temperatures they want in each of the upper stage and lower stage in the one-chamber gasifier according to coal properties and slagging control. The verification of this freedom was the base of the total results. Moreover, a reputation was being made that the gasification efficiency and process reliability are at the world's highest level.

    Research and development has been performed on a high throughput forming technology and a modularization technology for thin film poly-crystalline solar cell modules. This paper summarizes the achievements in fiscal 1999. In developing the high throughput forming technology for a high-quality thin film, research has been made on a low-cost VEST process to re-utilize substrates by separating the thin film from the substrate. In the melting re-crystallization process, it was discovered that plasticity deformation of the substrate can be reduced greatly by raising the substrate heating temperatures. It was also found out that substrate warping amount can be reduced to about one-fifth of the conventional amount by making the thickness greater than 1.5 mm and raising the heating temperatures higher than 1300 degree C. In developing the thin film modularization technology, it was indicated that the property improving effect remains the same even if the hydrogen passivation method is changed from the hydrogen ion injection to the hydrogen plasma processing. In the trial fabrication of the thin film modules, a conversion efficiency of 13.1% was achieved in nine-cell structured modules. (NEDO)

In the research of a large-area light absorbing layer manufacturing technology, investigation was made on light absorbing layers in manufacturing sub-modules with a size of 30 cm times 30 cm. With regard to the temperature condition in the light absorbing layer forming process, it was found that the cooling rate affects particularly the adhesion in the connecting interface of the light absorbing layer and the Mo rear electrode layer. In addition, it was revealed that the sulfur take-in amount can be increases by extending the retention time at the sulfurizing temperature and by decreasing the temperature to turn the gas phase into selenium. In the research of elementary technologies to establish the mass production process, developments were performed on the high-resistance buffer layer manufacturing technology, the high-quality window layer film manufacturing technology, and the technology to manufacture rear electrode layer made of high-quality metals.

Various cells were examined for temperature characteristics, and it was found that thin-film poly-Si cells present a temperature coefficient equal to or less than that of bulk single-crystal silicon systems, and hybrid cells a temperature coefficient similar to that of a-Si systems. The technology was applied to a hybrid solar cell in which an a-Si cell was placed on STAR structure thin film poly-Si cells, and a resultant 3-layer a-Si/poly-Si/poly-Si cell exhibited a stabilization factor of 12.0% after 550 hours of optical irradiation.

    Research and development was carried out for the production of a Cu(InGa)Se{sub 2}-based thin-film solar cell submodules, having a conversion efficiency of 13% and an area of 30 cm times 30 cm, at a cost of 140 yen/Wp (at a production rate of 100 MW/year). In the effort to fabricate a large-area photoabsorption layer, reproducibility was improved by the introduction of a technique for controlling the Cu/III group ratio in and the thickness of the metal precursor film by the use of ICP (inductively coupled plasma) analysis. A maximum conversion efficiency of 12.93% and a reproducibility of 85% were achieved, which meant that the production cost goal was achieved. In the effort to develop a high-resistance buffer layer fabrication technology, a fabrication method was developed in which a lower limit was specified for solution transparency enabling the completion of the film fabrication process with no colloid formation occurring in the solution. For preventing the high-resistance buffer layer fabrication process from growing too complicated, the steps were integrated into one for the MOCVD-ZnO:B window layer. As the result, the film fabrication process subject to the film fabrication control based on solution transparency was simplified for a great increase in reproducibility. (NEDO)

    This paper reports the study results on the fabrication technology of thin film polycrystalline Si solar cells in fiscal 1994. (1) On the fabrication technology of high-quality Si thin films, the new equipment was studied which allows uniform stable melting recrystallization over a large area. The new equipment adopted a heating method based on RTP system, and is now under adjustment. (2) On the fabrication technology of light/carrier confinement structure, degradation of hydrogen-treated thin film Si solar cells by light irradiation was examined. As a result, since any characteristic degradation was not found even by long time light irradiation, the high quality of the cells was confirmed regardless of hydrogen-treatment. Fabrication of stable reproducible fine texture structure became possible by using fabrication technology of light confinement structure by texture treatment of cell surfaces. (3) On low-cost process technology, design by VEST process, estimation of cell characteristics by simulation, and characteristics of prototype cells were reported. 33 figs., 1 tab.

    With an objective to manufacture low-cost large-area solar cell modules, developmental research has been performed on a film manufacturing technology using the dessolution deposition process. This paper summarizes the achievements in fiscal 1999. The research has been performed on a technology to form a thin silicon film directly on carbon substrates being substrates of different kinds, without using seed crystals. The researches made up to the previous fiscal year has made possible to form the film onto a substrate of about 5-cm square, has fabricated cells although with a small area, and indicated the importance of reducing concentrations of impurities in the solvent metals used. The researches performed during the current fiscal year executed modifications to reduce the temperature distribution in the substrate surfaces, including size increase in the heater, and improvement in the cooling heat conduction mechanism. As a result, films were formed successfully on 7.5-cm square substrates. In reducing the process temperatures, it was made clear that films can be formed at lower than 700 degrees C by using zinc as a solvent metal. Furthermore, the purity enhancement in the solvent metal achieved a conversion efficiency of 11.6% although the area is as small as 3.73 cm{sup 2}. (NEDO)

    The aim is to manufacture the above at low cost by a dissolution/deposition method. Under this method, a film is fabricated containing crystals high in quality and large in size though the film area is very small. In fiscal 1998, an effort to fabricate a film to cover a 10cm square substrate failed. The failure is explained by that the heater was too small for the substrate area and that the failure to uniformly heat the substrate resulted in an inplane temperature distribution greater than expected. The furnace was modified in a minor way to narrow substrate temperature distribution as much as possible. Another attempt was made to fabricate a larger-area film on a 5cm square substrate, and then crystals grew to cover approximately the whole surface of the 5cm square substrate. Efforts will continue to achieve the goal. As for the mechanism of film fabrication on substrates of different kinds, self-coating is now described by difference in heat conductivity between a carbon substrate and silicon substrate. Thanks to individual control in a small film fabricating unit, a film thickness of approximately 100 micrometers was achieved. The distance of diffusion was 30 micrometers or more in the case of a small area, and the efficiency of a solar cell using this film was found at 10.2%. (NEDO)

    Research and development was performed by noticing on the plasma spraying method as a process that can manufacture thin poly-crystalline silicon films at a high speed. Fiscal 1997 has established a technology that can form a silicon film directly without using seed crystals in an area of 2-cm square on a carbon supported substrate by using a small film manufacturing equipment using the dissolution and deposition process. The size of the crystal is as very large as several hundred {mu}m, by which a possibility of making high-performance solar cells was verified. Discussions were given to apply this technology to large-area substrates, whereas a device was developed, which is capable of forming a film in an area corresponding to 10-cm square. According to a film forming experiment using this device, the film has begun being formed on part of a 10-cm square substrate, verifying the effectiveness of this method. While the film thickness is about 100 {mu}m, it was confirmed that the crystal size will not change even if the thickness is made mechanically as thin as about 50 {mu}m. Further discussions were given on enhancement of wettability by means of coating, and light enclosing structure. (NEDO)

    It is intended to develop thin film solar cells capable of mass production with high photo-stability and at low cost. Thus, the objective of the present research is to analyze the growth process of micro crystal silicon based thin films, the crystal being a high quality silicon crystal based material, and develop technology to manufacture high-quality micro crystal silicon thin films based on the findings therefrom. It was found that, when silicon source is available in cathode, pure hydrogen plasma forms micro crystal silicon films by using the plasma as a result of the chemical transportation effect from the silicon source. It was revealed that the crystal formation due to hydrogen plasma exposure is performed substantially by the crystals forming the films due to the chemical transportation effect, rather than crystallization in the vicinity of the surface. The crystal formation under this experiment was concluded that the formation takes place during film growth accompanied by diffusion of film forming precursors on the surface on which the film grows. According to the result obtained so far, the most important issue in the future is particularly the control of crystal growing azimuth by reducing the initially formed amorphous layer by controlling the stress in the initial phase for film formation, and by controlling the film forming precursors.

    Serious shortage is predicted on cokes for blast furnaces in the first half of the 21st century. In order to deal flexibly with the fluid world market in the future, it is necessary to have a technology developed, by which coals from coking coal to non-coking dust coal can be used. The Japan Iron and Steel Federation and the Center for Coal Utilization, Japan are working on research and development of a new process with enhanced environmentality and economy (SCOPE 21) as a coke manufacturing process to respond to the requirements arisen from the above situation. The process is assessed basing on basic technological seeds such as rapid coal heating and high-speed carbonization and reformation of middle to low temperature cokes. The organizations are moving forward an eight-year development program which has started in fiscal 1994. This paper reports the summary of the development, and results of investigations and researches performed during fiscals 1994 and 1995. Rapid heating tests, middle to low temperature coke reformation tests, and tests for plug transportation of high-temperature coal have been performed. It has been verified, for example, that rapid coal heating can improve coke strength. The development work is being promoted toward grain size distribution and upscaling problems. 5 refs., 16 figs., 2 tabs.

    Studies are made of optimum materials and methods for manufacturing low-carbon fuels for reduction in greenhouse gas emissions. When their thermal dynamic limits and the technological maturity are considered, it is inferred that no extensive improvement will be achieved by merely improving on the efficiency of the existing fuels. The use of various high-efficiency driving power sources utterly different in mechanism from the conventional ones, such as those for fuel cell-powered automobiles, and the promotion of the use of low-carbon fuels such as methanol and methane for all kinds of driving power sources including those for the said fuel cell-powered automobiles, will become necessary. The use will also be necessary of recyclable materials. The biomass resources, in particular, since they absorb CO2 gas in their growing process by virtue of photosynthesis, may be said to be free of CO2 gas emissions. They have their own problems, however, which involve the economy of energy consumed for their production, harvesting, transportation, and conversion into fuels. It is therefore required that their whole life cycle be studied before their greenhouse gas reduction effect may be correctly assessed. The quantities of resources available for the production of automotive low-carbon fuels, manufacturing technologies, etc., are first of all put in order for easy perusal. An effective way is assessed for the whole including the life cycle. (NEDO)

    The project aims to establish a manufacturing process that enables both high-quality CuInSe{sub 2} (CIS) film solar cell enlargement and cost reduction and to develop a device structure which uses less heavy metal for the purposes of increasing the CIS thin-film solar cell size and efficiency and decreasing environmental impact. Several element technologies have been established for increasing the area of high-efficiency Cu(In, Ga)Se{sub 2} (CIGS) solar cells. Concerning the enlargement of the photoabsorption layer which is to assume the most important role, it is found that a high-quality CIGS film, which is near homogeneous though within a 10cm times 10cm area, is fabricated by an in-line vapor deposition method. As for dead area reduction and high-speed patterning, it is found that laser scribing works effectively in the patterning of the window layer and photoabsorption layer. As for reduction in the use of heavy metal, a high efficiency of 16.2% is attained in a cell not using a CdS film as expected in the case of a cell using a CdS film, this thanks to a CIGS film surface reforming technique. The technique of junction formation for CIGS solar cells is improved, and then a true efficiency of 18.5% is achieved. (NEDO)

The research covered development of technologies to form high-grade Cu (In, Ga) Se{sub 2} (CIGS) film by using the multi-dimensional deposition process, component technologies for forming a rear electrode, a buffer layer and a transparent electrode, and patterning technologies. As a result of the research, thickness of the CIGS film was reduced to half as much as that of the conventional films, having achieved conversion efficiency of 13.1%, which corresponds to about 90% of the conventional CIGS solar cells. In addition, elucidation was made on the effect of an MoSe{sub 2} layer existing on interface with CIGS/Mo in a CIGS solar cell imposed on solar cell characteristics. In developing an Mo film laser scribing technology, intensity dependence of laser energy was made clear, the energy being required for scribing according to surface condition of the Mo film. (NEDO)

    A polycrystalline Si thin film formation technology is developed, which uses the flux process in which a reaction occurs between the target crystal and a flux component which is eutectic. Using this process, a crystal grain relatively large in diameter is obtained at a relatively low temperature. This method is now attracting attention as one of the technologies for producing crystalline Si film for use in thin-film polycrystalline Si solar cells. Especially when Al is used for flux, since Al is automatically doped into the target crystalline Si film, it is expected that the resulting film will serve as the ground for a photoactive layer provided with the BSF (back surface field) function which is important for the improvement of solar cell efficiency. A polycrystalline Si thin film is formed on a 2cm times 2cm-large glass substrate at a temperature not higher than 600 degrees C. It is recognized that films selectively oriented towards the (111) or (100) plane are acquired when other processes are employed. It is expected that the said Al-doped film provides a ground on which a BSF function-provided photoactive layer will be formed. (NEDO)

    Processing of a large amount of coal ash is a serious problem in considering the locational conditions of coal firing power generation plants. 46% of the coal ash was effectively used in 1985, and the remaining 54% was disposed at landfills on land and sea. Positive promotion of the effective use of coal ash is the necessity. A production method for an artificial lightweight aggregate utilizing coal ash was established by a joint research. The history of the research and development of this artificial lightweight aggregate (brand name: FA-lIGHT), outline of the manufacturing facilities, physical properties and result of use are introduced. The lightweight aggregates are used not only for the construction of multistoried buildings but also used as most suitable aggregates for making lightweight large scale panels and concrete secondary products such as lightweight blocks. FA-LIGHT is most suitable for use in the production of concrete lightweight aggregates, and can be used for hydroponic agriculture and for the improvement of drainage of land. Spread of its use is expected. 5 figs., 5 tabs.

    This paper describes an outline of solid fuel production process from brown coal and the investigation results of its elemental techniques. Dried coal is produced by this process which consists of a dewatering of crushed brown coal in oil-based solvent, a solid and liquid separation of slurry, and a remained oil recovery by heating. This process is characterized by the higher thermal efficiency compared with usual drying and the restraint of spontaneous combustion of product coal. It was revealed that solid fuel with low moisture, low ash, low sulfur, and suppressed spontaneous combustion property can be produced from Australian brown coal through this process. From the comparison between kerosene and fuel oil A, it was confirmed that the oil content during dewatering was smaller and the oil recovery by heating was easier by using a solvent with lower boiling point. It was also confirmed that the spontaneous combustion property can be suppressed using small amount of asphalt by solving asphalt in the solvent and adsorbing asphalt on the surface of brown coal. From these results, low rank coals including brown coal, which are difficult to use, are expected to be used as clean coal with low ash and low sulfur through this process. 2 refs., 7 figs., 2 tabs.

    Processed foods must be produced in mass, cheap and safe and should be suitable for the delicate taste of human being. Food tastes are effected by an outlook on human attitude, and the surrounding environment. And these factors are reflected to unit operation in food manufacturing and processing and it is clarified that there are many technical difficulties. The characteristics of unit operation for food manufacturing and processing are that the food materials are a multicomponent system, moreover, a very small amount of aroma components, taste components, vitamin, physiologically activation materials and so on are more important than the main components, and also inapplicable of the model centering to the most quantitative component. The purpose of unit operation in food manufacturing and processing is to produce the properties of matter matching to human sense, and therefore there are many problems left unsolved. The development of analytical technology also has an influence on manufacturing and processing technology. Consequently, food manufacturing and processing technology must be based on general science. It is necessary to develop unit operation with an understanding of mutual effect between food and human body.

    Research and development was conducted for enhancing productivity and energy conservation by rendering continuous and automatic the electromagnetic casting process for manufacturing polycrystalline silicon substrates for solar cells. In the manufacture of ingots for substrates by continuous electromagnetic casting, the chuck type system for feeding power to the melt plasma was replaced by a roller type system, and the power feeding position was moved to the high temperature region. Also, an on-line ingot slicing technique was established. In the manufacture of substrates at a slicing rate of 300 {mu}m/minute, productivity of 115,000 wafers/month, yield of 98%, and thickness tolerance of 30 {mu}m were achieved. A high-speed cleaning technique was developed using a jet stream, by which the cleaning time was reduced to 5 minutes and the slurry recovery rate was elevated to 95%. Based on these, substrate-related costs in the case of 100 MW/year production was calculated, which resulted in a cost of 98.8 yen/wafer (target: 103.3 yen/wafer) for manufacturing 15 cm square substrates from ingots and in a 15 cm square substrate slicing and cleaning cost of 135.1 yen/wafer (target: 135.4 yen/wafer).

    Living standards improving in developing countries especially in China are the most influential factor to determine the demand for Cu. Consumption of Ni will depend on the trends of advanced technologies such as Ni-hydrogen battery, fuel cell, shape memory alloy, hydrogen absorbing alloy, in addition to increase in global population and developing countries' living standards improvement. Co is far more dependent on advanced technologies than Ni is. On the land, Ni ore is increasingly lower in quality and Co is being retrieved from by-products of Cu production, both meeting the problem of unstable supply. Consideration is made to apply new extraction methods to Cu production; there are some potential resources for Fe and Mn. The Mn nodule exists in great quantities and is a attractive source of supply, but a long time will be required before it is exploited. It is necessary to speed up the study to exploit the Mn nodule, but first of all the problem of its competition with land resources in terms of cost has to be solved. It needs to be found out at what stage of production the Mn nodule is competitive with land products. In any case, Japan should undertake the efforts of marine resources exploitation leading other countries of the world. (NEDO)

    This report concerns the transportation and storage of hydrogen using metallic hydrides that perform absorption and desorption of hydrogen. Alloys useable for this purpose have to be capable of reversibly absorbing and desorbing hydrogen within a certain temperature range. In the absence of guidelines to follow in the quest for such alloys, the efforts at discovering them turned out to be a continual series of trials and errors. Researches were conducted into the hydrogenation reaction of Mg and Mg-based alloys and into hydrides of V-based alloys, and into Zr-based alloy hydrides such as the ZrMn{sub 2} hydride, ZrNiMn hydride, Zr(Fe{sub x}Mn{sub 1-x}){sub 2} hydrides, TiZrFe{sub 2} hydride, Zr{sub x}Ti{sub 1-x}(Fe{sub y}Mn{sub 1-y}) hydrides, etc. Also studied were the electronics of hydrogen in metallic hydrides, rates of reaction between Mg-Ni-based alloys and hydrogen systems, endurance tests for hydrides of Mg-Ni-based alloys, effects exerted by absorbed gas molecules during the storage of hydrogen in Mg-Ni-based alloys, effective thermal conductivity in a layer filled with a metallic hydride, metallic hydride-aided hydrogen transportation systems, chemical boosters, etc. (NEDO)

    Described herein are results of survey on brown coal liquefaction techniques and peripheral techniques, centered by COSTEAM process under development in USA, solubilization by alcohol and liquefaction and cracking with the aid of tetrahydroquinoline as the hydrogen donor under development in Japan, and low-temperature carbonization and new promising techniques. The COSTEAM process shows higher reaction rates, conversions and oil yields for brown coal liquefaction than the one using hydrogen gas. Some of the problems involved in this process high viscosity and oxygenated compound content of the product oil. The product oil is acceptable as fuel for power generating plants and can be produced at a moderate cost, but may be unsuitable as vehicle fuel. Coal liquefaction and solubilization processes are mainly represented by those which use hydrogen. The hydrogen cost, which is high, determines the product price. The processes which use alcohol or tetrahydroquinoline are still in the experimental stage. (NEDO)

In developing the technology to re-use demolished building lumbers, a method for removing metals attached to demolished building lumbers was established by using a magnetic separator and a metal detector, with which it was verified that iron can be removed nearly 100%. With regard to waste plastics, simultaneous use of specific gravity separation utilizing centrifugal force and electrostatic separation provided a prospect that metals and plastics of high melting points can be removed from mixed resins in waste household electric appliances, and that polypropylene (PP), polystyrene (PS), and ABS can be classified at high accuracy. In manufacturing waste wood and waste plastic boards, pilot plants were built to use the 'melt spray method', 'melt blow method', and 'laminating method' as the means to spray molten resin onto wood raw materials, wherein trials were performed on mixing molten resins with wood flakes, and on board forming.

On the fabrication technology of light-stable a-Si films, the film formation method possible to control combined hydrogen by repetitive formation/treatment was developed. The obtained high-quality light-stable a-Si film was featured by low defect density in a wide optical band gap range, and defect density of nearly 3 {times} 10{sup 16}/cm{sup -3} after light irradiation. The light degradation rate of the cell where the a-Si film was applied to i layer was relatively stable by 10% or less. The a-Si/a-Si double-layer tandem cell fabricated by this technology produced a high conversion efficiency of 10.5%. By applying {mu}c-Si material to photoactive layer as narrow band gap material, the cell with optical sensitivity even in long wavelength ranges more than 1000nm was obtained.

    Discussions were given on manufacture of raw material silicon for solar cells with regard to boron removal, solidification, finishing and refining of metallic impurities, refining of unutilized silicon scraps, and making them into wafers and solar cells after refining. This paper summarizes the achievements in fiscal 1999. With regard to purity deterioration due to contamination by boron containing silica powder generated during the boron removal in the manufacturing process, the facilities were modified resulting in the reduction thereof to 0.04 ppmw or less. Regarding the repetitive use of boron removing crucibles, the experiment identified the possibility of using them for more than three times. In trial fabrication of samples by using the solidification refining and cast integrated process, ingots of 550 mm square and about 300 mm high were obtained, which were sliced into 10-cm square materials for use as wafers. Measurement of the conversion efficiency has resulted in 13% or more which is almost equivalent in the center and edges of the ingot.

    In order to manufacture silicon for solar cells, development is intended on a technology to manufacture silicon (SOG-Si) for solar cells by means of metallurgical methods using metallic silicon with purity generally available as an interim starting material. The silicon is required of p-type electric conductivity characteristics with specific resistance of 0.5 to 1.5 ohm per cm, to be sufficient even with 6-7N as compared to silicon for semiconductors (11-N), and to be low in cost. While the NEDO fluid bed process and the metallurgical NEDO direct reduction process have been developed based on the technology to manufacture silicon for semiconductors, the basic policy was established to develop a new manufacturing method using commercially available high-purity metallic silicon as an interim starting material, with an objective to achieve cost as low as capable of responding to small-quantity phase production for proliferation purpose. Removal of boron and phosphor has been the main issue in the development, whereas SOG-Si was manufactured in a laboratory scale by combining with the conventional component technologies in fiscal 1991 and 1992. The scale was expanded to 20 kg since fiscal 1993, and a five year plan starting fiscal 1996 was decided to develop the technology for industrial scale. Fiscal 1997 has promoted the development by using the 20-kg scale device, and introduced facilities to develop technology for mass-production scale. (NEDO)

    In the proliferation stage of solar cells, a technology is required to manufacture low-cost SOG-Si that can handle small quantity production. Development is being made on a manufacturing technology using high purity metallic silicon (99.5%) as the raw material. Considering that the subject impurities are P, B and metallic impurities (Fe, Ti and Al), a manufacturing method consisting of the following processes is being developed: metallic silicon/phosphorus removal, solidification and rough refining/boron removal, solidification and fine refining. Discussions are being advanced on phosphorus removal by using a large electron beam fusion equipment, and at the same time, the discussions are supported by fabricating and installing a large equipment intended of removing boron and the metallic impurities. Boron is removed by oxidizing it with steam. Therefore, the basic mechanism of the equipment is to spray argon plasma added with steam onto the molten silicon surface. In boron removal, diffusion of boron onto the reaction interface in the primary reaction determines the rate. A boron removal rate for B/10 to 0.1 ppm of 45 kg/h as maximum was achieved. The derived silicon has met the requirement. (NEDO)

    It is intended to establish an energy saving type mass production technology to manufacture solar cell substrates by using the electromagnetic casting process. This paper describes the achievements in fiscal 1997. Preliminary experiments were performed for high-performance slicing processing and post-slicing rinsing to reduce the cost by enhancing productivity in the slicing process. Since there is a problem of mixing of contaminating raw materials due to diversification in raw materials, resistance and impurity concentration must be determined on each raw material as the materials for the Czochralski method. Then, the raw materials are sorted out referring to the determination results, and they can be used for the electromagnetic casting process upon optimizing them. As a result of having sliced an ingot of 15-cm square with a length of 40 cm by using a mass-production wire saw, an accuracy of 22.8 {mu}m was attained as intra-face variance when the required cutting time was 476 minutes and the substrate thickness is 348 {mu}, thus having obtained prospect for achieving the standard. Development was made on a water jetting rough cleaning machine to separate and remove slurries (oil and grinding particles) from the substrates after slicing, and an arm robot to accommodate substrates into cassettes, which provided processing velocity of 9 second per substrate. A problem of raising the speed remains to be solved. (NEDO)

    Described herein are the FY 1996 results of development of fabrication technologies for high-quality CuInSe{sub 2}-based photovoltaic cells. The Cu-Ga alloy/In-stacked precursor film is prepared for production of the high-quality thin-film absorber applicable to large-area module fabrication, and selenized by the vapor-phase selenization in a H{sub 2}Se gas atmosphere to produce the thin light-absorbing film in which In and Ga are present at graded concentrations. Increasing Ga alloy content in the CIGS-based thin-film photovoltaic cell fails to widen the forbidden band and improve V{sub oc}, and further optimization works are needed. The method is developed for production of thin-film buffer layer of sulfur-containing Zn compound which can give the cell characteristics equivalent to those of CdS generally used for CIS-based thin-film photovoltaic cell. It is clarified that the photovoltaic cell characteristics can be improved by use of a transparent electroconductive ZnO film of stacked structure, produced by a combination of RF sputtering and DC sputtering. For the patterning technologies necessary for forming series connection on a mini-module, the laser scribing method is applicable to the metal base-electrode, and the mechanical scribing method to the light absorber and window layer.

    Rapid production of metallurgical coke from non- and slightly coking coals was studied by pressurized hot-briquetting method. Coal specimens were filled into the mold after pulverizing, and heated at a constant temperature rise rate up to caking temperature under loading pressure to obtain caked coal specimens. Such specimens were then carbonized in nitrogen gas at 800[degree]C. As a result, the coke obtained was superior in compressive strength as compared with commercial cokes, however, its CO2 reactivity was very high requiring heating up to 1,000[degree]C to decrease it, while the reactivity was strongly dependent on coal kind. The optimum processing conditions for slightly coking coal were as follows; loading pressure: 10 [times] 10[sup 5] Pa or more, temperature range under loading pressure: 300-450[degree]C, temperature rise rate: 2-100[degree]C/min, and caking temperature: nearly 500[degree]C. No coke could be produced from coking coals because no volatile matter could be removed from it in a short time under pressure. 13 refs., 8 figs., 1 tab.

    The purpose of this study is to acquire fundamental knowledge about the factors for production and the physical properties of boards when wood powder is used as the main material and powder adhesive is used as the binder in the formation of wood boards under heat and pressure. The effects of temperature for pressing, specific gravity of board, and the ratio of adhesive on bending strength, internal binding force, and size and stability against moisture are investigated. The temperature behavior at the central area of boards under heat and pressure shows similar tendency of stagnation near 140degC which increases thereafter irrespective of the temperature of the hot plate in this experiment. The bending property increases linearly when the resin content is low, and shows the tendency of leveling off gradually when the resin content is larger than 20%. Linear relation with specific gravity if obtained in the 0.6 to 1.0 specific gravity range. Wood powder boards have high internal size stability in the thickness direction than ordinary wood boards. 13 refs., 11 figs.

    As part of establishing an environmental harmony type production system of chemical products, study and survey were made on PET bottles. Using the life cycle analysis method (LCA), a study was made for proposing a material recycle (MR) method which is environmentally and economically excellent in the stage of recycling waste PET bottles. The total cost of recycling can be reduced by 34% supported by a decrease in equipment cost and improvement in yield if there is no mixture of foreign substances such as aluminum caps and PVC bottles. However, the ratio of the amount obtained from the reduction to the total production cost is small, and it is necessary to take measures from a viewpoint of the cost in a total production process and environmental loads. In a survey in Kawaguchi city, PET bottles discharged from the business sector occupied 41% of all the discharge amount. In a survey in Yokohama city, very important data were obtained on PET bottles appointed as the second type under the recycle law. The quality of PET bottles to be brought to the recycling plant is important for effectively processing PET bottles in MR method. For achievement of MR which is low in cost and small in environmental load, needed were cooperation by citizens, the shipping management system in autonomous government, and changes in design and material quality to be made by the industrial circle. 8 refs., 64 figs., 68 tabs.

    This paper introduces the following technologies and countermeasures found to be successful in solving geochemical problems relating to the maintenance and management of geothermal power plants belonging to Kyushu Electric Power Co., Ltd. In controlling condensate properties,curtailment of pH fluctuation range by changing the injection point of NaOH,inactivation of sulphur bacteria by using chloramphenicol and prevention of slime loading of the condenser strainer by running of the cooling tower without make-up water were achieved. In the environmental countermeasures,it was concluded that Fe-ion injection method was most effective to remove As out of waste hot waters which are all reinjected into the underground formation now. By understanding the characteristics of the well eruption fluids,the attenuation mechanism of steam producing wells could be estimated, which were interference,re-eruption and degradation of the reservoir temperature caused by the reinjected hot waters. And the problems associated with the attenuation of steam producing wells have been solved fundamentally by taking proper countermeasures to eliminate the influence of reinjected hot waters. The atteunuation of reinjection well was found to be caused dominantly by silica loading at the permeable zone of wellbore and to be effectively solved by high temperature reinjection of the waste hot waters, controlling of temp. degradation of hot waters to be reinjected and prevention of air mixing. After applying proper countermeasures, the attunuation rate of the reinjection well has been fairly improved. 13 refs., 21 figs., 2 tabs.

    Research and development was conducted of a technology for manufacturing an ultrathin polycrystalline silicon solar cell capable of efficiency enhancement and cost reduction earlier than the types of polycrystalline solar cells now available on the market. In this fiscal year, a silicon melt/solidification experimenting apparatus was built for manufacturing high-quality silicon ingots. Using an apparatus with its performance similar to the newly built one, a preliminary experiment was conducted involving high-purity silicon ingot manufacturing. In the experiment, boron was added to 75 kg of silicon for semiconductor devices so that its resistivity may be 0.5 ohm-cm. The silicon was melted in a quartz mold, and then subjected to unidirectional coagulation at 0.13 mm/min that started at the bottom to proceed upward. The result was a silicon ingot 44 cm times 44 cm times 17 cm (height). The ingot thus obtained exhibited 0.4-0.8 ohm-cm in resistivity distribution. Solar cells produced from the ingot showed a conversion rate of 16.9%. (NEDO)

    Research and development has been made on improving quality of ingots for substrates, manufacturing high-quality thin type substrates, and making high-efficiency cells. This paper summarizes the achievements in fiscal 1999. In developing the high-quality ingot manufacturing technology, discussions were given on a method for assessing impurities and crystal defects by using the total reflection scattering type infrared tomography, and on the optimal solidifying and cooling conditions during the ingot manufacturing by using simulation calculation for solidification. As a result of analyses and discussions, such findings were found effective that the ingot should be solidified through making the solid-liquid interface shape flat, and the temperature falling rate in an ingot should be maintained constant. In developing the high-efficiency cell making technology, discussions were given on the optimal construction based on a simulation that assumes the light sealing structure using the RIE method, and on the optimal construction of polycrystalline silicon solar cells by using a device simulator (PCID). The important factors in achieving a conversion efficiency of 20% are the light sealing structure, surface passivation, and substrate thickness. (NEDO)

    Investigation has been made on the current status of food sanitation controlling technologies. Eighty percent of food poisoning is caused by bacte such as Salmonera, enteritis vibrio, staphylococcus, and pathogenic colibacillus. Putrefaction as the cause for food poisoning occurs from proliferation of different microorganisms. Heating sterilization is the main method being performed, but non-heating method may include sterilization by flash and high voltage pulse discharge in addition to ultra-high pressure and ultraviolet ray sterilization. As a result of the questionnaire survey, what is extracted as the problems in the food sanitation controlling technologies is to establish a rinsing and sterilizing method with large sterilization effect, an effective sterilizing method and thawing of processed marine products, and a cooling method in food processing. Increasingly demanded for the future is to develop a foodstuff sanitation control system using as the core the hazard analysis critical control point (HACCP, a quality control program developed by the U.S. NASA to ensure safety in manufacturing space food), and micro-organism control and sterilizing technologies to support the above system. The flash pulse and high-voltage pulse sterilizing technologies as the non-heating sterilizing technology are more effective than the conventional heating sterilization methods also from the aspect of quality retention after sterilization. More active development thereof is desired. (NEDO)

    Described herein are results of literature survey on brown coal liquefaction reactions and elementary techniques. Liquefaction of brown coal in the presence of CO and steam, or CO, H{sub 2} and steam has been investigated. It is not clear by the literature survey whether it is superior to the normal process which uses hydrogen. Brown coal contains moisture at high contents, and the drying techniques are necessary to be developed for its liquefaction. The future coal liquefaction plant will be much larger than the past one, and there are a number of problems to be solved, such as those involved in the designs of large-sized high-pressure slurry pumps, heat exchangers and preheaters. It is also necessary to develop the materials of and production techniques for large reactors which are serviceable under severe conditions. The solid-liquid separation for liquefaction products involves a number of the elementary techniques characteristic of coal liquefaction processes, and needs many technological developments. The one-stage brown coal liquefaction process is compared with the two-stage process for the secondary hydrogenation of SCR, but no clear conclusions are reached. (NEDO)

    This study is being progressed during a period from 1992 to 1999 as part of the NEDO`s clean coal technology program. This paper describes what has been discussed to date. The absorption method and the adsorption method may be used to recover CO2 as means to deal with the problem of global warming resulted from burning coals. These methods, however, have problems in economy caused from concentration of CO2 in flue gas being low. The present study is intended to raise the CO2 concentration in flue gas by using oxygen plus circulated flue gas in the place of combustion air, so that CO2 may be recovered as it is without being separated from the flue gas. Therefore, an oxygen-blown pulverized coal fired power generation plant having a cryogenic oxygen manufacturing equipment was designed to discuss the plant operability and economy, and the pulverized coal combustion technology by using a dynamic simulation. A large number of findings have been obtained already, and the study has reached a level at which grasping the whole image is now possible. 13 figs.

    This paper describes chlorination substituting disinfection technologies used in water purification systems. Chloramine treatment is regarded as effective in reducing trihalomethane (THM). Chlorine is injected in the initial stage in the form of free chlorine to disinfect pathogenic microorganisms in a short time, which is then added with ammonia to convert it into chloramine for further utilization. Chlorine dioxide has not been used in Japan, but introduced in Europe and America to treat THM. Ozone has the strongest oxidizing power, and is used for disinfection, virus inactivation, decomposition of THM precursors, and removal of fungus odor. The ozone treatment will produce aldehyde if an organic matter is present, but aldehyde can be removed by treatment using organismic activated carbon. Ultraviolet ray treatment has an advantage of being difficult of producing byproducts. This system was experimentally compared with free chlorine treatment on disinfection effect, mutagenicity, suppression of producing THM byproducts, and odor removal. In order to assure reliability of microorganismic and chemical safety in tap water supply systems, assurance by considering the entire system is important, not only by operating the disinfection units, but also combining such physical water purifying technologies as coagulation, sedimentation, filtration, and membrane treatment. The use of chlorine substituting disinfectants is also a part of the conception. 6 refs., 8 figs., 5 tabs.

    In order to grasp the phenomena actually occurring in the combustion chamber for improving the combustion and for reducing the exhaust gas emission of the diesel engines, the visualization techniques are becoming to be essential and indispensable. The authors have observed the spray and combustion, when proceeding the combustion improvement by the high pressure injection, and then have performed the image processing and simulation calculation based on them. The high pressure injection devices used for the experiment are the intensifier type and accumulator type which can generate the injection pressure more than 200MPa, and both of them are the electronic controlled hydraulic drive type, and are driven separately from the engine. Since it was found that the analysis of high pressure injection by the hologram is limited in the conditions, as for the spray, the spray analysis was performed by the transmitted light attenuation method and laser sheet method. As for the combustion, the engine for observing the combustion was trially made, and then the combustion state was observed by the high speed photograph. Furthermore, the flame temperature analysis by the image processing using the combustion photograph and the analysis of flow and turbulence of the flame were carried out. 9 refs., 16 figs.

    This paper describes features of high power YAG cutting. The optical fiber transmission YAG laser machining system has some advantages in which optical path length compensation unit is not required and measures for low power loss and dust are not required, when compared with the CO2 laser system. Its application to the cutting of stainless steel plates has attracted attention. Cutting tests of SUS304 were conducted using high power YAG laser. Cutting of SUS304 plate with a thickness of 40 mm could be successfully done at the power of 3.5 kW. Cutting tests of SUS304 pipes with a thickness of 8 mm in water under the depth of 20 m were also conducted using air as assist gas at the power of 2.5 kW. Excellent results were obtained without scale deposition. For the tests by the composite beam using 3 kW and 4 kW systems, SUS304 plate with a thickness of 50 mm could be cut at the cutting speed of 0.1 m/min. Laser cutting of pipes from the internal surface was conducted using a newly developed small machining head which can rotate in the peripheral direction. Excellent quality for welding was confirmed. Cutting speed and plate thickness were improved by combining water jet cutter and YAG laser unit. 6 refs., 10 figs.

    A bio-reaction of microbes (catalytic reaction by an enzyme) is characterized in that the reaction is carried out at a normal temperature and under a normal pressure and has particularly high specificity with respect to substrate (reactant). It is considered that a low loading process of environment harmony type can be constructed by applying the bio-reaction in petroleum refinery process. CO{sub 2} exhaust and energy consumption in the bio-desulfurization (BDS) is estimated to be 70 to 80% lower than those in hydrodesulfurization (HDS). The bio-technologies that can be applied to the petroleum refinery process include, for example, desulfurization, demetallation, dewaxing, denitration, cracking and so on. In this paper, the present state of bio-desulphurization technology is introduced. Particularly, as the research results in Japan, acquirement of mesophile R.erythropolis KA2-5-1 strain, thermophile Paenibacillus sp.

    Because the prestressed concrete (PC) cable-stayed bridges combine the distinctive features such as a rationality of the structure or a structural beauty, it will not stay on a development of the technologies to make them longer and larger, and a rationalization of the execution, an investigation from various aspects such as the scenery design, material selection, pursuit of new structure and so forth will become necessary. In a main meeting, 15 volumes of paper on the most advanced technologies of PC cable-stayed bridges were presented. The presentations from Japan were 11 volumes, and occupied about 70%, and therefore a high interest to the PC cable-stayed bridges in Japan was inferred. In the presentation from Japan, there were many relevancies of the important study themes which would become a foundation for a development of PC cable-stayed bridges in the future, like ones that an improvement effect of dynamic behavior such as the aseismatic property, wind endurance and so forth was made as an objective, ones that a safety evaluation at an ultimate state as the oblique member anchoring part, main tower or entire structure was related, ones that a construction of the various control systems when the cable-stayed bridges were executed was concerned and so forth. 23 figs., 1 tab.

    Tandem type solar cells are developed, in which solar cells with different band gaps are stacked for effectively utilizing optical energy across the entire range of solar spectrum. A material gas supply control device for multiple epitaxial growth was added to a large-area GaAs film epitaxial growth unit, and a film thickness homogeneity of {+-}1% was achieved. A GaInP epitaxial layer fabricated in the same way was also enhanced in homogeneity. A low-carrier concentration layer was inserted into the top cell GaInP p-n junction for the construction of a p-i-n structure, and this improved on the short-circuit current. Furthermore, a p-p-i-n structure was constructed having two emitter layers, and this improved on spectral sensitivity for the achievement of a conversion efficiency of 13.6%. Studies were conducted about the tunnel junction which plays an important role in the stacking of cells, and the tunnel peak current was increased to 7.41A/cm{sup 2}. Fabrication is now under way of a GaInP/GaAs stacked cell, which is expected to exhibit a conversion efficiency of 25% or higher. In the case of a GaInAs cell to serve as the bottom cell, a conversion efficiency of 5.1% was achieved. Consequently, it is safely expected that a 3-junction stack of GaInP/GaAs//GaInAs will exhibit a conversion efficiency of 30% or higher. (NEDO)

    Research and development has been performed on laminated cells comprising of GaInP/GaAs//GaInAs using poly-element compound semiconductors. This paper summarizes the achievements in fiscal 1999. In developing the technology to manufacture large-area ultra-high efficiency cells, fabrication of 5-cm square GaAs cells was worked on, and a conversion efficiency of 24.7%, which is equivalent or better than that for 1-cm square cell, was achieved by using the epitaxial growth temperature for the GaAs cell structure of 600 degrees C, by adopting the p-on-p structure and by making the electrode thicker by using the plating method. Furthermore, trial fabrication was performed on 5-cm square cells also on GaInAs as the bottom cell. A conversion efficiency of 4.6% was obtained in a 5-cm square cell as a result of high level homogenization of film thickness and composition by optimizing the gas flow in growing GaInAs onto an InP substrate, and using a growth temperature of 550 degrees C. In developing the technology to form GaInP/GaAs laminated cells, discussions were given by using 5-mm square cells on especially improving the GaInP crystallinity and reducing the series resistance in the window layer. GaInP/GaAs-2 bonded lamination cells were fabricated, whereas a conversion efficiency of 19.63% was obtained without using a reflection preventing film. (NEDO)

    This paper describes the achievements in fiscal 1999 on development of the technology to manufacture glycocluster controlled biological molecules, particularly bio-fibers. It was made clear for the first time that the method for synthesizing glycoside and sugar chain using solid ultra-strong acid can be a new method for polysaccharide synthesis (polycondensation reaction) which is extremely simple and versatile as a result of using the solid ultra-strong acid. It can also be applied to general glycoside synthesis. In glycopeptide synthesis of the regular sequence type using high-functional condensation reaction, such a condensation agent as diphenyl phosphoryl azide was found effective in polymerization reaction without protection of glycopeptide, which has been impossible conventionally, and was found to have high versatility as a method for synthesizing mucin glycoproteins widely distributed naturally. In simplified synthesis of physiologically active glycopeptide, notice was given to tyrosine which is not glycosylated in the natural world, even though having hydroxyl groups in side chains as in serine and threonine. A method was established to introduce sugar chains into this hydroxyl group. This method exhibits power also in the synthesis of physiologically active glycopeptide of non-natural type. The paper describes also the comprehensive survey. (NEDO)

    R and D was conducted with the view of establishing hydrogen production technology based on the solid high polymer electrolyte water electrolysis method, which presumably offers higher efficiency and lower cost than conventional methods. This year, as well as implementing development of large-scale cell lamination (electrode area 2,500 cm{sup 2}, 10 cells) by using two hydrogen production methods (electroless plating method and hot press method), work was started for developing cells (electrode area 1,000 cm{sup 2}) for hydrogen stations. In the research on longterm durability improvement, with a 50 cm{sup 2} membrane electrolyte or cell, the evaluation test results were obtained of stable electrolytic performance showing more than 93% energy efficiency after 400 hour operation, under the conditions with electrolysis pressure 0.4MPa and electrolysis temperature 120 degree C. In a test of 1,000 cm{sup 2} prototype cell for hydrogen stations, the evaluation result was obtained for energy efficiency of 92% under the conditions with electrolysis pressure 0.5MPa and electrolysis temperature 120 degree C; thus, this year's target efficiency of over 90% was achieved. Further, enhancement of the quality was contrived for example by improving the electroless plating method and remodeling a roll press machine. (NEDO)

    Efforts are made to develop a GaInP/GaAs-based compound semiconductor solar cell built on an Si substrate, the Si substrate being lower in cost, higher in mechanical strength, lighter in weight, and higher in heat conductivity than a GaAs or Ge substrate. Fiscal 1999 studies involved improvement on GaAs/Si heteroepitaxial growth and the evaluation of crystallinity in thus grown layers, improvement on cell characteristics, fabrication and evaluation of an n{sup +}/p structure cell, and so forth. As for crystal growing technologies, a 980 degree C 5-heat-cycle annealing method was applied, and the density of dislocation was reduced to 5 times 10{sup 6}cm{sup -2}. In the fabrication of cells, an n{sup +}/p structure cell was studied, and the cell achieved 12.5mAcm{sup -2} in short-circuit photoelectric current over 9mAcm{sup -2} of the conventional p{sup +}/n structure GaInP cell. Without any special effort to optimize the structure, a GaInP/GaAs layer-built cell on a GaAs substrate achieved 23.7% in conversion efficiency. When it is taken into consideration that conversion efficiency on an Si substrate is approximately 80% of what is achieved on a GaAs substrate, it is deemed that the achievement of 23.7% suggests that near 20% in conversion efficiency may become available on an Si substrate.

    Low-cost monosilane production technologies are studied for film formation on amorphous solar cells. In fiscal 1984, the monosilane generation system modified in the preceding fiscal year is subjected to an extended operation for stability test for improvement on the process. The purity of monosilane produced during the stability test operation is found to satisfy the target level, and this means that the system operates at high efficiency. As for electrolysis, important problems arise with detriment to the practical application of this method. Though a solution is found for each of the problems, yet the problem of how to prove their effect remains to be solved. As for technologies for monosilane purity evaluation, a CVD (chemical vapor deposition) proving furnace is built, and research is started as to how to perform purity estimation using the characteristics of silicon layers epitaxially grown on high-resistance silicon substrates. The monosilane is examined, and it is found that its has a spreading resistance of 1,000 ohm-cm against the 2,000 ohm-cm of monosilane available on the market. Since the characteristics determined in this way are greatly affected by the conditions set for CVD, it is necessary to make further efforts to enhance optimization. (NEDO)

    As a WE-NET subtask, a study has been conducted of the solid polyelectrolyte water electrolysis method by which higher efficiency and lower cost hydrogen production is expected than in the conventional hydrogen production method. Production methods of electrode, electrolyte, etc. were studied. In the electroless plating method, the manufacturing process of membrane-electrode assemblies was realized in a large area of 2500 cm{sup 2} by the porous-surfaced method by studying manufacturing conditions for slurry membrane/membrane assembly/electroless plating processes. In the hot-press method, the refining degree and dispersibility of iridium dioxide powder were studied to improve characteristics of anode catalyst. A method was developed to form polyelectrolyte coatings homogeneously on the surface of electrode layer catalytic powder, and a large area of 2500 cm{sup 2} was realized. Beside the performance test using large single cells, FS was conducted to discuss optimum operating conditions and optimum structures of plants. Both methods indicated the performance exceeding the energy conversion efficiency of 90%, a WE-NET target, at current density of 1A/cm{sup 2} and electrolysis temperature of 80degC.

    Research and development have been carried out with an objective to re-utilize waste cable covering materials as oil substituting energy. The research has been performed on behavior of chlorine and lead being substances that impede making the cable covering materials into fuel, development of a technology to remove chlorine, lead and copper, and pelletizing properties for fuel making. In the study of behavior of chlorine and lead, the following matters were made clear: dechlorination reaction completes within 30 minutes if pyrolysis temperature is higher than 300 degrees C; the more the amount of filler CaCO3 in test samples, the less the dechlorination amount; and secular deterioration does not affect the dechlorination amount. A technology has been developed successfully to remove the substances that hinder making the cover materials into fuel, achieving the target values of copper at 0.2% or less, lead at 0.3% or less, and chlorine at 5% or less. In developing the pelletizing technology that puts the cover materials into raw materials for blast furnaces, dechlorination rate of 90% was achieved by mixing coke/PVC at a ratio of 1/1 and dechlorinating it by using a rotary kiln. It was verified that the product is free of problems in particle size as the blast furnace raw material. (NEDO)

    With an objective of decreasing silicon usage quantity for the purpose of reducing the solar cell production cost, development is being performed on an ingot cutting technology to cut a silicon ingot to Kerf loss of 150 {mu} m and thickness of 150 {mu} m, and in which the produced wafers can withstand the cell making. Investigations revealed that a wire saw is suitable as the cutting system, and the wire used must have a diameter of less than 120 {mu} m, and a strength of more than 3850 N/mm{sup 2}. A prototype wire was fabricated, whose diameter is 120 {mu} m, and in which the strength is distributed between 3870 and 4110 N/mm{sup 2}. It was found possible that a wire of 160 {mu} m can be used to slice an ingot having a cross section surface of 150 mm square and a length of 300 mm into a slice having a Kerf loss of 200 {mu} m and a thickness of 180 {mu} m. This wafer had the in-plane distribution of the substrate thickness at {+-} 12.5 {mu}, swell of 120 {mu} at maximum, and surface roughness of 5 {mu}. Making ten of these wafers into a cell resulted in a yield of 60%. Assignments are the clarification of the properties of the cutting wire, the preparation of a thin wire with homogeneous quality, and the establishment of a technology to cut Kerf loss of 150 {mu} and substrate thickness of 150 {mu}.

    In the use of hydrogen as fuel, there is the problem on NOx emission. The amount of NOx emission is not as much as in the use of coal or oil, but is more than in the use of natural gas or town gas. However, it can be said that hydrogen is an ideal fuel if considered that it does not emit other air pollutants such as CO, HC and soot/dust which are usually associated with hydrocarbon base gas fuels, and also that hydrogen forms a circulation system which is ecologically sound. The flame of hydrogen is non-luminous, but the flame temperature is high. The formation of NOx depends strongly upon the flame temperature, and therefore, in the design of hydrogen burner, it is necessary to well mix it with air and to avoid the production of the local high temperature region. Further, when using hydrogen to large boiler, the combustion technology to control NOx reduction is needed. About the hydrogen flame, the matter to be noticed is an experimental result that NOx reduction was observed by adding trace ammonia to hydrogen gas. If this method can be successful, NOx can be reduced with no increase in fuel consumption. It leads to hydrogen's reaching a position of clean energy. (NEDO)

    For the purpose of preventing closed waters from eutrophicating, COD regulations and nitrogen and phosphorus waste water regulations are executed in Japan, but practically applicable techniques for this purpose are a few. Concerning technology for removing nitrogen and phosphorus in waste water, this paper describes the actual situation of two industries, electroplating and alumite processing, and applicable techniques. Among various nitrogen removal methods, the biological treatment method has been used practically in many cases and is applicable to practical use. While there are many kinds of physical and chemical treatment methods, applicable methods are limited. In removing nitrogen, the coagulating sedimentation method with Ca salt, Al salt and Fe salt is effective generally for orthophosphate. At electroplating factories, various forms of phosphorus and nitrogen compounds are used as plating chemicals. In treating waste water containing phosphorus, the coagulating sedimentation method is used most frequently. The oxidation + coagulating sedimentation method, the autolysis + oxidation coagulation method, and the evaporation method are effected, though the examples of their implementation are small in number. 15 tabs.

    This paper introduced the sensor technology for food manufacturing industry. If sugar concentration in main raw material is too high in the amino acid fermentation, control of the concentration is required because fungi growth is inhibited. A controlling method for sugar concentration was developed by using the correlation between consumption of NH {sub 3} for pH adjustment and sugar consumption in place of conventional analyzing method and was introduced in the gulutamic acid fermantation. BOD sensor was developed to enable the selective measurement of organic substances which can be processed by organisms, and measuring time was shortened from previous five days to 30 minutes. Since many organics absorb infrared ray, near infrared analysis is suitable for food analysis and on-line analysis has high possibility. When this method is applied to measure moisture in fishes and meats, continuous measurement can be made nondestructively and without contacting, and further the precision is {plus minus} 0.1%. Simultaneous multi-composition analyses are carried out by continuous spectrum and near infrared method using higher rate scanning. Sensor development for taste and smell has started. 10 refs., 4 figs., 4 refs.

    The survey/research project is implemented for establishing environment-compatible energy systems in urban areas by constructing wide-area heat supply networks to exchange energy among cities. This project studies, taking Kanagawa Pref. as the model area, distributions of unutilized energy sources, and possibilities of their utilization for heat supply. There are large quantities of unutilized energy, including waste heat from power plants, general works and cleaning works, and low-temperature waste heat from, e.g., sewage and pumping systems. The district air conditioning promotion areas are selected from those consuming large quantities of heat energy in the prefecture, and their characteristics are grasped. The effects of the networks on total energy consumption of the entire prefecture are estimated for the cases of introducing the district air conditioning systems or wide-area heat supply networks in these selected areas. Introduction of optimum advanced heat utilization systems in stereotyped areas is also considered, in order to predict the effects of introduction of wide-area heat supply networks. (NEDO)

    Described herein are emission control technology and exhaust gas cleaning measures for internal combustion engines. Gas turbines burn relatively high-quality fuels, such as natural gas, kerosene, diesel oil and gas oil, where the major concerns are to reduce NOx and dust emissions. The NOx abatement techniques fall into two general categories; wet processes which inject water or steam, and dry processes which depend on improved combustion. Power generation and cogeneration which burn natural gas adopt lean, premixed combustion and two-stage combustion as the major approaches. Low-speed, large-size diesel engines, which realize very high thermal efficiency, discharge high concentrations of NOx. Delayed fuel injection timing is the most easy NOx abatement technique to meet the related regulations, but is accompanied by decreased fuel economy. Use of water-emulsified fuel, water layer injection and multi-port injection can reduce NOx emissions without decreasing fuel economy, depending on optimization methods adopted. Automobile gasoline engines are required to further clean exhaust gases by catalystic systems. 9 refs., 10 figs., 6 tabs.

    In this research, the data of advanced technology of micromachines in the USA have been searched, collected, and arranged from the US patent information, technical journal information, and newspaper and general journal information. According to demand, the main undertaking information was interviewed from well-informed persons. The data were compiled as advanced technology trend of micromachines in the USA. Sensors are remarkably predominant in the elemental technology. There are also important topics in the fields of actuators, motors, lenses, devices, and structures. On the other hand, materials, etchings, packages, motive powers, and softwares are also important elemental technology in spite of their less information. From the viewpoint of usage, detection systems are remarkably predominant. Then, robots, processing systems, optics, analysis systems, motive power systems, medical systems, and acoustic systems are also important. From the viewpoint of industrial sector, the environmental items are predominant. Automobiles, medical treatments, and information communications follow the above. When new relationships to the secondary usage and tertiary usage are not found, it would be rather hard to express such a technology development trend more clearly.

    Regulations, conventions and agreements relating to the discharging liquefied carbon dioxide (CO2) into the bathypelagic zone from a cruising ships are investigated. The ocean storage of CO2 is not specifically prohibited by law, but must be regulated on a global scale because such treatment may impact the marine environment. In principle, treatment with impact on the nature is prohibited. Laws of environmental conservation are completed in European, Asian, and Pacific countries, which join international conventions and committees with high interests. It is suggested that the engineering technique of the storage should be improved to observe regulations and that an impact assessment for the ocean storage should be carefully conducted in full understanding of the basic premise of the regulatory systems or organizations. Furthermore, it is significant to study on the possible effect of the ocean storage of CO2 on global warming and life-cycle assessment inventory analysis, namely the balance of the energy budget between the separation and the ocean storage of CO2. 23 refs., 7 figs., 6 tabs.

    Inside the jet engine, the propulsion engine for an aircraft, a high speed air current is flowing, and the rotors such as the fan, compress or, turbine and so forth are rotating with a high speed in its flowing current. The flow itself in which a high speed exhaust jet is discharged in the air from engine exhaust port, and the aerodynamic noise generated by an interaction of the flow with the material bodies are the main noise sources of the aircraft engine. Because the supersonic planes are necessary to fly with mach number 2 - 3 during cruising, the turbojet engine with a large jet exhaust speed or the low bypass ratio turbofan engine is selected. Since a noise reduction by reducing the jet exhaust speed, which was an effective measure for the high subsonic speed passenger plane, can not be applied, a reduction of the supersonic jet noise, which is hard to be reduced, becomes a necessity. In addition, in recent years, a research and development of the advanced turbo prop (ATP) aircraft with a further higher thrust efficiency are advanced as well. The aerodynamical noise reduction technologies of these engines for supersonic airplanes are summarized. 14 refs., 11 figs., 1 tab.

    For the foundation improvement works by grouting in a borehole, evaluation of grouting effect is one of the most important management items. The grouting design and works are sometimes reconsidered depending on the evaluation of grouting effect during the test injection. The purpose of the evaluation of grouting effect is to grasp the range of improvement and consolidation after the injection, and to judge and estimate the strength and permeability of the consolidation part. This paper describes the judgment method of the strength using PS logging results and borehole televiewer (BHTV) logging results. The reflection intensity (Ir) by the BHTV logging increased after the grouting, which showed a same tendency as that using S-wave and P-wave velocities (Vs and Vp) before and after the grouting. This was considered to demonstrate the grouting effect. A relation was obtained between the Vs, Vp and Ir before and after the grouting, which was expressed by following equation. Ir=0.143{times}Vs-70=0.093{times}Vp-110. The relation with the dynamic elastic coefficient (Ed) was also obtained as follow; Ir=0.0013{times}Ed. 9 figs.

Subjects were told to perform three different tasks in a climatoron, and the relation between physiological indices and their perception of fatigue as well as their capability of performing the tasks were analyzed. As a result, heart rate variability is a good index for quantitative evaluation of mental load and fatigue. 5 refs., 4 figs., 6 tabs.

    Among all bi-magnetic core(transition metal)@shell(transition metal oxide) nanoparticles (NPs), Ni@NiO ones show an onset temperature for the exchange bias (EB) effect far below the Néel temperature of bulk antiferromagnetic NiO. In this framework, the role played by the magnetism of NiO at the nanoscale is investigated by comparing the microstructure and magnetic properties of NiO and Ni@NiO NPs. With the aim of bridging the two systems, the diameter of the NiO NPs (~4 nm) is chosen to be comparable to the shell thickness of Ni@NiO ones (~2 nm). The EB effect in Ni@NiO NPs is attributed to the exchange coupling between the core and the shell, with an interfacial exchange energy of ΔE~0.06 erg cm{sup −2}, thus comparable to previous reports on Ni/NiO interfaces both in thin film and NP morphologies. In contrast, the EB detected in NiO NPs is explained in a picture where uncompensated spins located on a magnetically disordered surface shell are exchange coupled to the antiferromagnetic core. In all the studied NPs, the variation of the EB field as a function of temperature is described according to a negative exponential law with a similar decay constant, yielding a vanishing EB effect around T~40–50 K. In addition, the onset temperature for the EB effect in both NiO and Ni@NiO NPs seems to follow a universal dependence with the NiO crystallite size. - Highlights: • Comparison of the exchange bias effect in NiO and Ni(core)@NiO(shell) nanoparticles. • Universal temperature dependence of the exchange bias effect. • Suggested similar physical origin of the effect in both systems. • Size and crystallinity of the NiO shell hold the key for exchange bias properties.

    This report describes the results of effective fixing technique of CO2 by utilizing solar energy. First of all, the investigation was directed to the technique for synthesizing ethylene, hydrocarbons and alcohol by electrochemical reduction of CO2. The power required for this process is supplied by photovoltaic power generation. Development of excellent electrode catalyst is needed because the reduction of CO2 requires a high overvoltage. It is desirable to enhance the selectivity of the reaction for specific material and improve the transport process in the electrolytic cell. Next, designing of material and reaction of photocatalysts using semiconductor electrode and semiconductor particulate was examined. A semiconductor electrode made of FeS2 is inexpensive and has a high ability of collecting solar light. In the category of photocatalysis system, a photocatalytic system in which semiconductor particles are embedded in vesicle and a photpocatalyst based on potassium niobate are noteworthy. As biosystem, the method of reducing CO2 by calcareous algae which simultaneously advances fixing and calcification of CO2 by photosynthesis is noteworthy. 129 refs., 45 figs., 20 tabs.

    For the purpose of developing the future innovative energy technology, the paper described a strategic point of view. Effects of the energy issue are remarkable on the next generation and thereafter as seen in the finite of energy resource, global-scale environmental changes, the increasing energy demand, natural/social influences of large-scale technology development. If the technological development is going on in the same way as until now, there will appear limits. Relating to the strategies, to seek what energy should be among the strategies, it is necessary to consider not only global-scale problems but particular conditions in Japan (self-sufficiency, international cooperation, creativity, etc.) Also, wisdom and technique are necessary to attain it. Technological development in a wide sense plays a major role in the energy strategy. Technology innovation must be advanced according to the energy strategy. Integrating ideology into the development of energy technology and selecting therefrom developmental subjects which meet the purpose, required is the construction of the energy system with high flexibility and functionality. Looking at the conventional way of thinking from a different angle and posing a future pull plan, Japan should show leadership to the world. 20 refs., 25 figs., 8 tabs.

    Ni-2V, Ni-5V, Ni-12V, Ni-10Cr, Ni-20Cr, and Ni-3Nb alloys were carbonitrided in C 3 H 6 and NH 3 gas mixtures (bal H 2 ) over the range 700--1,000 C. Carbonitridation of Ni-12V and Ni-20Cr in C 3 H 6 /NH 3 /H 2 (1.5/1.5/97 v/o) and (1.5/10/88.5 v/o) produced duplex subscales consisting of near-surface nitrides with underlying carbides. Growth of each zone obeyed the parabolic rate law under most conditions. The presence of carbon generally did not effect the depth of the nitride zones compared to nitriding the alloys in NH 3 /H 2 (10/90 v/o). However, at 700 C, the nitride zones were deeper in the carbonitrided Ni-V alloys and Ni-20Cr. The presence of nitrogen generally increased the depth of the carbide zones in Ni-12V and Ni-20Cr compared to carburizing these alloys in C 3 H 6 /H 2 (1.5/98.5 v/o). VN, CrN, and NbN formed in Ni-V, Ni-Cr, and Ni-Nb alloys, respectively, whereas the underlying carbide layers contained V 4 C 3 in Ni-12V, Cr 3 C 2 above a zone of Cr 7 C 3 in Ni-20Cr, and NbC in Ni-3Nb. The solubilities and diffusivities of nitrogen and carbon in nickel were determined. Nitrogen and carbon each exhibited retrograde solubility with temperature in pure Ni in both carbonitriding environments. Nitrogen diffusion in nickel was generally lower in each carbonitriding mixture compared to nitrogen diffusion in a nitriding environment, except at 700 C when nitrogen diffusion was higher. Carbon diffusion in nickel was generally higher in the carbonitriding environments compared to carbon diffusion in a carburizing environment

    Research and development has been performed on a technology to manufacture hydrogen effectively from water utilizing solar beam and using an organics oxidizing and reducing system as the intermediary, and its achievements in fiscal 1984 was reported. With regard to the process in hydrogen generation stage as the first step, water dissolvable rhodium complex was synthesized to improve the process having been developed in the previous fiscal year. Its photo-hydrogen generation capability was discussed. In the rhodium complex of ligand having sulfonic acid group for water solution, a system using only water as a solvent was discovered to show the photo-hydrogen generation capability equivalent to or greater than the system of organic solvent and water using non-water dissolvable rhodium complex. In the stage of reduction of oxidized type organics by water as the second step, discussions were given on photo-electrochemical behavior of iron oxide sintered electrodes. Photo-hydrogen generation was investigated by retaining the electrode potential to a potential generated by beam irradiation onto the iron oxide sintered electrodes, and using a system of water dissolvable rhodium complex and rhuthenium complex. As a result, a possibility of recycling the materials was discovered. (NEDO)

    An investigational study was conducted of a project for energy conservation and greenhouse effect gas reduction by introducing the steam injection gas turbine generator to production facilities of the Siam Cement Industry Corporation (SCI) in Thailand. In the project, studies were made on the following: no purchases of electric power by introduction of the steam injection gas turbine generator; additional heating by gas turbine exhaust gas by introduction of the kiln combustion air heater; remodeling of the preheater of raw materials, and the partial calcination before kiln sintering by introduction of the calcination furnace. As a result of the study, the energy conservation amount was 1,200 toe/y, and the greenhouse effect gas reduction amount was approximately 8,000 t-CO2/y, which led to the reserve power for increased production of clinker by about 18%. The size of investment was 314.5 million Baht in total. As to the evaluation of economical efficiency of the investment, the actual period of ROI was a little less than 5 years, and the internal earning rate was 17.7%, which substantially met with SCI's standards for equipment investment. However, there are problems on the gas supply infrastructure, recovery of the white cement demand, etc. (NEDO)

    This paper describes the achievements in developing a high-calorie gas manufacturing technology for coal gasification in the Sunshine Project in fiscal 1981. Pulverized coal and heavy oil are heated and stirred to make it a slurry, which is forced into a fluidized bed gasification furnace together with spraying steam, and pyrolyzed by using a unique slurry feeding system (a hydrohoist). Carbon-like material as a by-product (char) is partially oxidized (burned) by steam and oxygen at the lower part of the gasification furnace. The material is gasified in the furnace, where the generated heat is sent to the pyrolysis zone in the upper part by the gas and fluidized bed media particles (char), and utilized as a heat source for the slurry pyrolysis. The produced gas is cooled by an indirect heat exchanger of the fluidized bed system and a scrubber to separate tar, dust and unreacted steam. Part of the sensible heat is recovered as steam. Thus, high-calorie gas of 6,000 kcal/Nm{sup 3} can be obtained, which is rich in methane, CO and hydrogen. Fiscal 1981 has performed a continuous test by using an internal heat type low-pressure gasification equipment to evaluate its compatibility to the diversification of materials. (NEDO)

    Recently, a proposal was made of employing the hydrogen storage alloy produced by means f rapidly solidifying single roll method, i.e., a method of projecting the molten alloy onto the surface of roll rotating in high speed as for the negative electrode material of the metal hydride alkaline battery. However, the hydrogen storage alloy produced by the single roll method has a heterogeneous grain size. This invention solves the problem. The Mm{center_dot}Ni{center_dot}Co{center_dot}Al{center_dot}Mn alloy ribbon with average thickness of 0.08 - 0.35 mm is produced by means of single roll method. The grain size of the alloy is over 0.2 micrometer on roll surface side and below 18 micrometers on open surface side. The alloy is ground to be used for the hydrogen absorbent. The general formula of this alloy is MmR(x) (Mm = mischmetal, R = Ni, Co, Al, Mn). In this way, the metal hydride alkaline battery with excellent high rate discharge characteristic at the initial stage of charge-discharge cycle, excellent charge-discharge cycle characteristic, and excellent inner pressure characteristic can be produced. 2 figs., 5 tabs.

In an aircraft field, since the major theme is application of new technologies to new airframe development, with joining in international cooperative development of aircraft, Japanese initiative development of airframes based on the domestic market demands and profitability should be started as early as possible. Because there is no airframe development by only one country including U.S.A., Japan is profitable to unite with some overseas companies, and invest selectively in specific leading fields. Positive technical support to safety, reliability, comfort and environment harmony are also important. More important theme than establishment of elementary technologies is preparation of an integrated flight demonstration system to expand application chances of development results, and preparation of various test facilities for tests required during development activities. Application of information technologies to the whole aircraft industry, and organic cooperation between the private and public sectors are also important. (NEDO)

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a steel technology field. Japanese steel industry should correspond to requirements of the international economic society as the top runner. Although it is now difficult to suppose a basic technology innovation, stable supply of basic materials is necessary for peripheral industries. The basic raw material technology is the basis of domestic and overseas socio- economic activities. The technology development support system to retain the world-wide leadership of Japanese industries is a strategic issue. Preparation of cooperative R and D bases of industry, academia and government along a national policy is important. Strong promotion of such national projects is also essential as global environment problem, positive use of advanced information tools, development of technologies and products of unexplored fields, and development of new products and demand creation according to social needs. Such measures along social requirements are also important as raw material development to double an energy efficiency, and the policy and system to construct a recycling society and living spaces.

    The paper described the results of the survey of the nonferrous metal field relating to the FY 1999 long-term energy technology strategy. The needs for electronics products are increasing toward the 21st century. Domestically the competition with other countries in enlarging the market share has been intensifying. At the same time, the smaller the size of device becomes, the more the barriers in technology to be overcome increase. In the development of Si wafer to cope with such a situation, there are a lot of problems to be broken down in liaison with industry/government/university. Compound semiconductors are higher in speed than Si, and have a marked feature of producing light, but are difficult in crystal growth.

    The paper described the results of the survey of the nonferrous metal field relating to the FY 1999 long-term energy technology strategy. The needs for electronics products are increasing toward the 21st century. Domestically the competition with other countries in enlarging the market share has been intensifying. At the same time, the smaller the size of device becomes, the more the barriers in technology to be overcome increase. In the development of Si wafer to cope with such a situation, there are a lot of problems to be broken down in liaison with industry/government/university. Compound semiconductors are higher in speed than Si, and have a marked feature of producing light, but are difficult in crystal growth. It was in the past 20 years that the development of commercialization technology has rapidly advanced. Compound semiconductors are indispensable as a device in the energy problem which strongly influences the global environment. In the U.S., for the military use, a policy for upbringing national industries has been carried out since 1993. The role of compound semiconductor materials playing as the fundamental industry which supports the semiconductor industry and system industry as the nation's core industries is important even in Japan the same as in the U.S. (NEDO)

    This paper describes the achievements in fiscal 1999 on development of a basic technology to design and fabricate an innovative light-weight structure. Taking CFRP and aluminum alloy having excellent specific strength as the main object materials, weight reduction and reliability enhancement in aircraft structure are intended, while reducing largely the number of parts. In particular, the wings, the nose and the leading edge construction of civilian aircraft are of the structure assembled with a large number of parts, and are suitable as the research objects. A new conception will be introduced that structural members are fabricated by utilizing the characteristics of integrally formed CFRP, which will be assembled into a whole structure. Large structural metallic members currently used have such drawbacks as the use of great number of parts, complexity in manufacturing processes, low reliability, weight increase and corrosion due to rivet jointing. In order to solve these problems, development will be made on technologies for thin-wall large-size precision casting, and high-accuracy high-quality welding. To combine different kinds of members, and optimize strength, weight and economic performance of the entire structure, high-efficiency integration technologies will be discussed, and prototype full-size structure will be fabricated. The current fiscal year has started up the technology committee and its operation, analyzed technological problems in the entire structure, and established the action programs. An investigation was performed on the technological trends in overseas countries. (NEDO)

    The following results were obtained by fundamental studies on molten salt/lime slurry bath gasification method. A comparison between a gasification process in a literature and the subject process shows the characteristics as follows. It is necessary to withdraw a high temperature molten salt slurry from under pressurization to atmospheric pressure and to separate only the ash content from other components; however, a large burden of this operation is a problem. In addition, CaO reacts with a part of the ash, making complete recovery of CaO difficult. From these two reasons, the subject gasification process has disadvantage, compared with the fluidized-bed process, against coal that contains much ash content. The gasification process, however, has the following advantage. It can reduce oxygen usage. It is unaffected by the grain size and caking of coal. The reaction rate of CaO in carbonation is several times greater in molten salt than in a fluidized bed. The heat of reaction of CaO for carbonation is an exothermic reaction and can supply several tens of percentages of the heat of reaction in coal gasification. The desulfurization effect of CaO is great. Molten salt has a catalytic effect, making particularly the reaction rate of methanization several times greater. (NEDO)

    As to the development of coal use hydrogen production technology, the paper made the test study on the improvement of gasifier use materials and evaluation of the characteristics, the evaluation test in the environment using the actual machine, etc., and the FY 1993 results were reported. The results of the study were as follows. Concerning the shaped refractory for gasifier hearth, it was found that high chromia base and picrochromite base refractory development materials had much more excellent coal slag resistance than other existing component-system materials. It was shown that the development materials began to deteriorate under the coal gasification environment at temperatures of about 1,500 degrees C or higher. As to the mullite ceramics, a possibility was shown of improving the slag permeation resistance by making the crystal grain coarse by long-time sintering. By the survey of the state of damage of the proposed materials (refractory and iridium) used in the operational environment of the pilot plant, the outlook for use limit was made clear. In the environment test using the actual machine on the proposed metal base alloy of the typical equipment of the pilot plant, the correspondence between the operational environment and material corrosion was made clear.

    The compound semiconductor production process is tested under a microgravity by the space experiment/observation free flier (SFU), to reduce the photovoltaic power generation cost. Described herein are the FY 1996 results. The device is confirmed to work as planned by the full-scale test conducted in FY 1995, when it stood on the orbit and was recovered by the space shuttle STS-72 January, 1996. The recovered SFU-carried devices, including the electrical furnace and related subsystems, were found to normally function, and it was concluded that they could be evaluated and analyzed after the flight. The comprehensive evaluation and analysis of their electrical, mechanical, thermal functions have confirmed that they functioned and showed performance as planned, demonstrating validity of the designs and production procedures. The test samples were taken out of the recovered combined furnace, focus furnace and single-heat furnace for the space environment utilization tests. The other samples had much more uniform compositional distributions than those produced on the ground. (NEDO)

    This research and development endeavor is based on Tokyo University's technical seeds and aims to put on the market Al{sub 2}O{sub 3} based CFCC (continuous fiber ceramic composite) materials. They do not break down and are shapable into large or complicate forms as required, which features are not to be expected from a single ceramic material, and are usable in a high temperature oxidizing atmosphere. High purity alumina fiber and alumina-silica fiber containing 70% of Al{sub 2}O{sub 3} were selected, and woven. The resultant cloth was baked at a low temperature for burning away organic impurities. The cloth was then immersed in a zirconia sol containing 30wt% of the stock solution, and was allowed to dry at 105 degrees C. An alumina slurry was prepared containing a dispersant and a binder, and was applied to the zirconia-soaked cloth until it was as thick as desired. The cloth was kept at 800 degrees C for 1 hour for degreasing, and was baked at a low temperature where no heat caused degradation of the ceramic fiber would occur. Specimens stand long use when the temperature is 1,300 degrees or lower for high purity fiber and approximately 1,150 degrees or lower for alumina-silica fiber. They withstand 30-100MPa, dependent on the manufacturing conditions and the kind of fiber used. (NEDO)

    A transmission electron microscopy (TEM) based investigation of microstructural development during transient liquid phase bonding of near-stoichiometric NiAl to commercial purity nickel is presented in this article. The work described employed Ni-4.5 wt pct Si-3.2 wt pct B (BNi-3) melt-spun interlayers. The precipitation of both Ni-Al based phases and borides within the joint and adjacent substrate regions is discussed. The article considers martensite formation (within the NiAl substrate) and the precipitation of L1 2 type phases (both within the joint and at the interface with the NiAl substrate). The relative roles of the two substrate materials (NiAl and Ni) in the isothermal resolidification process are identified. The preferential formation of Ni 3 B boride phases in the Ni substrate near the original location of the Ni substrate-joint interface is discussed and contrasted with the absence of similar events in the NiAl substrate

    It needs long time to carve a molding die of bumper, which has a large and deep cavity. To shorten the milling time, we must make the machining more performable and accurate, and develop the new technology of CAM. In the milling sequence, Primary Roughing, which cut out 90% of the stock, should be more and more performable. So we established Tilt-Plunging and Curve-Fit Spiral Cutting techniques. These techniques will reduce lateral force to the tool, and make remains more small. With the techniques, we reduced both machining and NCdata preparing time to one half. 1 ref., 14 figs.

    Japan-U.S. comparative research was made on technology transfer and innovative industry support. The U.S. industry is greatly benefited by universities, which is consequently strengthening the international competitiveness of the U.S. economy. However, the partnerships between private firms and universities have no fixed pattern, and keep changing dynamically. Business incubators increased to 627 rapidly, and mainly supported by municipal governments and universities. The U.S. has a well-established mechanism of technology transfer, and has succeeded in many cases. Not only universities but also national laboratories commit to technology transfer to venture businesses, and after starting businesses, entrepreneurs can use various hedging systems which are expected to play a role promoting the future technology innovation. The U.S. also has many advanced areas for sustainable technology innovation, like Silicon Valley, and these areas contain many supporting bodies to help new businesses. The activity of these bodies is very suggestive to Japanese local platforms promoting technology innovation and new local industry creation.

    As to high performance/high function plastic materials used in power generation facilities, technical trends were surveyed on the recycle situation and recycle R and D to study the subjects to be solved. For wire covering materials, vinyl chloride, polyethylene, rubber, etc. are used, and the recycle of resin has not been advanced. Concerning the generation of waste plastic, the existence of a lot of plastics different in characteristics makes the recycle difficult. As to the use of waste plastic as resource, the material recycle and recovery of combustion energy are being made, but only a part of the plastic is reused as chemical raw materials. Relating to the R and D of the chemical recycle technology, there are sample studies on the pyrolysis of polyolefine, dechlorination of chlorine base resins, etc. Recently, the following have been made public: proposal of depolymerization monomer based on the cyclic monomer, study of liquefaction of approximately 100% of the thermosetting resin, approach to the solvolysis by supercritical solvent.

    The WE-NET Project is a long-term project designed to ensure that an energy network technology using hydrogen becomes a reality not later than 2020. So the project cannot remain effective unless constant efforts are made to foresee future trends of technology and optimize it as the making of entire system for the project. In this project, new technologies which are not up for development are also investigated. Their feasibility should be studied, if necessary. From the foregoing point of view, new technologies are studied, collected and evaluated. Thus, useful suggestions and proposals may be made as to the course for the project to follow, as well as its research and development. Proposals highly evaluated up to FY 1995 are the hydrogen-oxygen internal-combustion Stirling`s engine, hydrogen production by solid oxide electrolysis, magnetic refrigeration technology for liquefaction of hydrogen, solar thermal hydrogen production with iron sponge technology, and hydrogen producing technology with photocatalyst. Conceptual investigation themes in FY 1996 are the hydrogen internal-combustion Stirling engine, solar thermal hydrogen production, phototransformation process, and high-temperature steam electrolysis. 9 figs., 54 tabs.

    In connection with contamination of soil and ground water, a survey was made on domestic patent information and existing literature or the like, in view of remediation technologies capable of in si-tu or on-site treatment, with arrangement and classification carried out by the method of cleaning contaminants. Arranged and classified were 209 pieces in the patent information, and 145 pieces in the literature from Geo-Environmental Protection Center, an incorporated body. In the methods of extracting contaminants from under the ground, the majority was the methods of pumping up ground water and those of excavating and removing. In the methods of cleaning contaminants, those of 'separation by heat', 'separation/decomposition method using water' and 'suction of gases' are found roughly in equal numbers. In the trend of the patent information, remediation technologies have started in 1990's, while bio-remediation as well as technologies of separation/decomposition through water is still increasing in the number of applications. Meantime, solidification technologies reached a peak around 1998 and have been decreasing in recent years. In the technologies of late, combinations of plural cleaning methods are also seen for the purpose of dealing with contamination with high to low concentration and compound contamination including organo-chloric compounds, heavy metals, etc. (NEDO)

    Study was made on production technology of the 5th- generation material 'eco-smart composite structure' based on micro-capsule technology. This material ought to have an intelligent function including self-detection and self- restoration of defects, environmental harmony, high strength and long life. At present, these demands are implemented by embedding a sensor, actuator and controller in structure, or optical fiber, shape memory alloy and computer chip in matrix, however, such complex material structure has adverse effect on environment. On the other hand, single structure material such as biodegradable polymer is unusable in severe environment such as the ocean and space. These problems can be resolved by combining composite material and micro-sphere technology, for example fiber-reinforced plastic (FRP) composite structure including micro-capsules with nano particles.

    Nickel/titanium nanolaminates fabricated by sputter deposition exhibited rapid, high-temperature synthesis. When heated locally, self-sustained reactions were produced in freestanding Ni/Ti multilayer foils characterized by average propagation speeds between ∼0.1 and 1.4 m/s. The speed of a propagating reaction front was affected by total foil thickness and bilayer thickness (layer periodicity). In contrast to previous work with compacted Ni-Ti powders, no preheating of Ni/Ti foils was required to maintain self-propagating reactions. High-temperature synthesis was also stimulated by rapid global heating demonstrating low ignition temperatures (T ig )∼300-400 deg. C for nanolaminates. Ignition temperature was influenced by bilayer thickness with more coarse laminate designs exhibiting increased T ig . Foils reacted in a vacuum apparatus developed either as single-phase B2 cubic NiTi (austenite) or as a mixed-phase structure that was composed of monoclinic B19 ' NiTi (martensite), hexagonal NiTi 2 , and B2 NiTi. Single-phase, cubic B2 NiTi generally formed when the initial bilayer thickness was made small.

    The paper described the results of the survey of the fine ceramics technology field relating to the FY 1999 long-term energy technology strategy. The fine ceramics industry is a new industry for which the future development is expected. It has far-reaching effects on other industries. Japan has the advantage over other countries. As subjects to remarkably develop the industry, needed are the long-term basic preparation which promotes technology innovation such as the promotion of the fundamental/creative R and D, construction of an industry/university liaison system, and arrangement of the intellectual base. Preparation of the competitive environment and promotion of policies paying attention to the market are needed which make the development under the private control by creative study/corporate activities possible. Also important are the demonstration of leadership and secure international competitive force in the light of Japan's international position. For the private-control development, the role and course of various groups should be made clear from a long-term aspect. It is desirable that university/government will newly develop innovative technology, and industry will make the present technology force more developmental and competitive. Support from the nation is requested for researches large in scale. (NEDO)

    The survey/study were conducted to contribute to proposing technology strategies such as the analysis of the present state of technical competitive force and the forecast in the airplane technology field. In future airplane industry, to meet the requests/restrictions from the society in the international airplane industry in the recent years, it is predicted that technology innovation will advance centering on the following four fields: next generation airplane technology to enable the innovative cost reduction in development/production, technology to realize the substantial reduction in flight cost of airline, technology to enhance reliability for the next generation flight which meets the multi-frequency flight/increasing demand for small plane, and airplane frontier technology. Moreover, regulations especially on noise, CO2 reduction and NOx reduction are becoming very strict internationally because of the increasing concern about global environmental problems. It is urgently needed to establish technology to cope with these trends. As the comprehensive strategy, the following are considered: development of airframe under the leadership of Japan and securing of the demand, efficient arrangement and operation of large-scale experimental facilities, IT adoption to the airplane industry, organic cooperation by industry/university/government, etc. (NEDO)

    Discussions were given on a sterilizing effect of ozone on Fusarium bacteria in hydroponic culture, and its effect on components in the culture solution. In an experiment, dry air with O3 concentration of 3.5 ppm was sent into aqueous solution inoculated with Fusarium bacteria at a flow rate of 5 liters per minute. The Fusarium bacteria was sterilized nearly completely in about five minutes. No change was observed in pH, EC and dissolved oxygen concentration of the O3-treated culture solution. However, iron and manganese among the soluble components have been oxidized by O3 and precipitated, hence these components must be added after the O3 treatment. In spinach culture performed on a culture medium inoculated with Fusarium bacteria, ozone water containing dissolved O3 at 0.8 ppm was flown into a urethane foam medium and vegetable roots. This treatment has resulted in reduction of the number of strains occurred with a wilt symptom below that in the section flown with distilled water. The spinach has grown normally without showing an effect of the ozone water. 15 refs., 10 figs., 3 tabs.

    Nanostructured Co-Ni/Co-Ni oxides were electrochemically deposited onto stainless steel electrode by electrochemical method and characterized for their structural and supercapacitive properties. The SEM images indicated that the obtained Co-Ni/Co-Ni oxides had cauliflower-type nanostructure. The X-ray diffraction pattern showed the formation of Co 3 O 4 , NiO, Co and Ni. The EDX elemental mapping images indicated that Ni, Co and O are distributed uniformly. The deposited Co-Ni/Co-Ni oxides showed good supercapacitive characteristics with a specific capacitance of 331 F/g at 1 mA/cm 2 current density in 1 M KOH electrolyte. A mechanism of the formation of cauliflower-shape Co-Ni/Co-Ni oxides was proposed.

    This work investigates the charge transfer and Al(Ga) p-Ni d hybridization effects in the intermetallic Ni/sub 3/Al(Ni/sub 3/Ga) alloy using the NiL/sub 3.2/- and K-edge and Al(Ga)K X-ray absorption near edge structure (XANES) measurements. We find that the intensity of white-line features at the NiL/sub 3.2/-edge in the Ni/sub 3/Al(Ni /sub 3/Ga) alloy decreased in comparison with that of pure Ni, which can be attributed to the enhancement of Ni3d states filling and the depletion of the density of Ni 3d unoccupied states in the Ni/sub 3 /Al(Ni/sub 3/Ga) alloy. Two clear features are also observed in the Ni/sub 3/Al(Ni/sub 3/Ga) XANES spectrum at the Al(Ga) K-edge, which can be assigned to the Al(Ga) unoccupied 3p (4p) states and their hybridized states with the Ni 3d/4sp states above the Fermi level in Ni/sub 3/Al(Ni/sub 3/Ga). The threshold at Al K-edge XANES for Ni/sub 3/Al clearly shifts towards higher photon energies relative to that of pure Al, indicating that Al loses charges upon forming Ni/sub 3 /Al. ...

  16. Nitriding behavior of Ni and Ni-based binary alloys

    Fonovic, Matej

    2015-01-15

    Gaseous nitriding is a prominent thermochemical surface treatment process which can improve various properties of metallic materials such as mechanical, tribological and/or corrosion properties. This process is predominantly performed by applying NH{sub 3}+H{sub 2} containing gas atmospheres serving as the nitrogen donating medium at temperatures between 673 K and 873 K (400 C and 600 C). NH{sub 3} decomposes at the surface of the metallic specimen and nitrogen diffuses into the surface adjacent region of the specimen whereas hydrogen remains in the gas atmosphere. One of the most important parameters characterizing a gaseous nitriding process is the so-called nitriding potential (r{sub N}) which determines the chemical potential of nitrogen provided by the gas phase. The nitriding potential is defined as r{sub N} = p{sub NH{sub 3}}/p{sub H{sub 2}{sup 3/2}} where p{sub NH{sub 3}} and p{sub H{sub 2}} are the partial pressures of the NH{sub 3} and H{sub 2} in the nitriding atmosphere. In contrast with nitriding of α-Fe where the nitriding potential is usually in the range between 0.01 and 1 atm{sup -1/2}, nitriding of Ni and Ni-based alloys requires employing nitriding potentials higher than 100 atm{sup -1/2} and even up to ∞ (nitriding in pure NH{sub 3} atmosphere). This behavior is compatible with decreased thermodynamic stability of the 3d-metal nitrides with increasing atomic number. Depending on the nitriding conditions (temperature, nitriding potential and treatment time), different phases are formed at the surface of the Ni-based alloys. By applying very high nitriding potential, formation of hexagonal Ni{sub 3}N at the surface of the specimen (known as external nitriding) leads to the development of a compound layer, which may improve tribological properties. Underneath the Ni{sub 3}N compound layer, two possibilities exist: (i) alloying element precipitation within the nitrided zone (known as internal nitriding) and/or (ii) development of metastable and

    Non-uniform distributions of Ni 4 Ti 3 precipitate crystallographic variants are investigated in a Ni-rich NiTi shape memory alloy after aging, assisted by external stress. A finite-element method model is presented that considers the elastic anisotropy of the B2 parent phase and also mutual misorientations of grains in a polycrystalline sample. On loading by the external stress, the stress is redistributed in the microstructure and the precipitation of some Ni 4 Ti 3 crystallographic variants becomes distinctly favorable in grain boundary regions since these variant configurations minimize the elastic interaction energy. The volume fraction of the affected grain boundary regions is calculated and the numerical results are compared with the data obtained by differential scanning calorimetry and transmission electron microscopy

    For the construction of a recycling system consuming less energy and therefore higher in efficiency, studies were made about the feasibility of metallic material developing/recycling systems more congruent with the objective through the application of inverse manufacturing (IM). Concerning metallic materials and recycling technologies, steel, aluminum alloys, and magnesium alloys were taken up, and a survey was made of hazardous elements in steel materials, unification of materials to constitute aluminum alloy parts, yield of magnesium in die casting, and the like. In the survey of recycling of automobiles, it was pointed out that the treatment of resin-based shredder dust was posing problems and that the use of metallic materials high in recyclability was essential to IM. In conclusion, three propositions were presented, which involved technologies for the advanced use of magnesium alloys as materials leading to the realization of IM, the development of recycling-oriented general-purpose alloys (with Mg and Al as mother metals), and the development of functional bonding technology enabling debonding (debondable bonding technology).

    The aim is to develop a technology for detecting environmental pollution before it becomes apparent and thereby to contribute to the development of technologies to minimize the damage that may be inflicted upon the global environment. For this purpose, researches are conducted in search of techniques to detect, at high speed with high sensitivity over a wide scope, the response of living organisms to chemicals. In a research on the application of the reaction of ecosystem to environmental stress, communication between living organisms in coping with environmental chemicals is investigated. It is then found that the growth of vegetable roots may be used as a measure for the detection of environmental pollutants but that the method is too low in sensitivity. A research is conducted on the creation of an ecological reporter function using the biological amplification technique. It is then found that the immunoreaction-aided measuring of environmental pollutants yields an excellent result in terms of sensitivity but that it has a problem in its resistance to environmental conditions. In a research on the standardization of environmental measurements using ecological information, it is found that the primary object of research and development should be a systematization technology compatible with biological functions.

  3. Electronic structure of Ni-- and Ni2--ethylene cluster complexes

    1978-01-01

    The electronic structure of metal cluster--ethylene complexes has been investigated by carrying out ab initio bonding pair-correlated, self-consistent field, and configuration interaction (CI) calculations on the NiC 2 H 4 and Ni 2 C 2 H 4 species. The π-NiC 2 H 4 and π-Ni 2 C 2 H 4 cluster complexes are found to be bound, the former only with CI, while disigma-Ni 2 C 2 H 4 has only a repulsive Ni 2 --C 2 H 4 ground state potential curve. The bonding in the π-type cluster complexes can be described as follows: The metal atom configuration is 3d 9 4s 1 with the 4s hybridized (by the metal 4p) away from the ethylene molecule, thereby allowing the π orbital to form a dative sigma bond with the metal atom. The bonding interaction is promoted by the presence of a second nickel atom behind the first one, leading to a 4s orbital electron deficiency of the bonded nickel atom and thus making this nickel atom a better electron acceptor. Back donation from the occupied metal 3d into the ethylene π* molecular orbital also takes place to some extent, and thus both features of the classical Dewar--Chatt--Duncanson model are observed. The π-Ni 2 C 2 H 4 species is analyzed in terms of the addition of a bare nickel atom to a π-NiC 2 H 4 cluster complex, with concomitant stabilization of the orbitals of the bonded nickel atom. A study of the excited electronic states of π-NiC 2 H 4 shows that low-lying 4s→π* and 3d→π* (M→L) charge transfer transitions are predicted. The former is not observed experimentally, probably due to the diffuse nature of the 4s orbital. The relationship between small cluster--ethylene complex systems and ethylene chemisorption on a nickel metal surface is discussed

    Applications of 63 Ni in biological research are reviewed, with emphasis upon recent investigations of nickel metabolism and toxicology in experimental animals. The radiochemistry of 63 Ni is summarized, including consideration of the preparation of certain 63 Ni compounds (e.g. 63 Ni(CO) 4 and 63 Ni 3 S 2 ) that are of current interest in toxicology, teratology and cancer research. Practical guidance is given regarding the detection and determination of 63 Ni in biological materials by autoradiography and liquid scintillation spectrometry. (author)

    The structural transition in NiAs was studied by neutron diffraction on the single crystalline sample. The crystal structure of NiAs has been reported to be bottom-centered orthorhombic with Cmc2 1 symmetry (niccolite-type). The measurement of temperature dependence of the powder X-ray diffraction revealed that NiAs undergoes a structural transition to the NiAs-type at T t =335 K. In present neutron diffraction experiment at room temperature, we observed the reflections indexed on the basis of the orthorhombic unit cell. The intensities of these reflections are qualitatively explained in terms of the niccolite-type structure with taking account of three domain structures, except for the weak reflections indexed as (001), (003) and (012). Then, the intensities of (001), (002) and (004) reflections were measured in temperature range of 20 to 420 K. The temperature dependences of (002) and (004) reflections qualitatively agree with those of the calculated intensities using the atomic positions of niccolite-type structure. However, the temperature dependence of (001) reflection shows the anomaly around T t , which suggests the symmetry of crystal structure of NiAs is not the Cmc2 1 symmetry. (author)

    In this study, an electroplating method to deposited Ni, crystalline NiW(c-NiW), amorphous NiW (a-NiW) films on P-type Si(1 0 0) were used to form Ni-silicide (NiSi) films. After annealed at various temperatures, sheet resistance of Ni/Cu, c-NiW/Cu and a-NiW/Cu was measured to observe the performance of those diffusion barrier layers. With W added in the barrier layer, the barrier performance was improved. The results of XRD and resistance measurement of the stacked Si/Ni(W)/Cu films reveal that Cu atom could diffuse through Ni barrier layer at 450 deg. C, could diffuse through c-NiW at 550 deg. C, but could hardly diffuse through a-NiW barrier layer. c-NiW layer has a better barrier performance than Ni layer, meanwhile the resistance is lower than a-NiW layer.

    Giant magnetoimpedance (GMI) effect on NiFe thin film is very promising due to its application in developing the magnetic field sensors with highly sensitivity and low cost. In this paper, the single layered NiFe thin film and NiFe/Cu/NiFe thin film with a meander structure are prepared by the MEMS technology. The influences of sputtering parameters, film structure and conductor layer width on GMI effect in NiFe single layer and meander NiFe/Cu/NiFe film are investigated. Maximum of the GMI ratio in single layer and sandwich film is 5% and 64%, respectively. The results obtained are useful for developing the high-performance magnetic sensors based on NiFe thin film.

  8. High Ni in Archean tholeiites

    Arndt, Nicholas T.

    1991-03-01

    Archean tholeiites generally have higher Ni, Co. Cr and Fe than most younger tholeiites with similar MgO contents. These characteristics cannot be attributed to high T or P batch melting in the Archean mantle, because, although such melts are enriched in siderophile elements, they have higher MgO than normal tholeiites. As primary melts fractionate to lower MgO, they lose Ni, Co and Cr. Nor can the differences between Archean and younger tholeiites be attributed to secular variation in mantle compositions because Archean komatiites have Ni, Co, Cr contents similar to modern (Gorgona) komatiites. It is suggested that the high siderophile element content of Archean tholeiites results from mixing of either komatiitic with basaltic magmas, as might occur in an ascending, melting mantle plume or column, or of komatiite and more evolved rocks, as may take place when komatiite encounters and assimilates crustal rocks.

    For the physical modeling system of Technology Research Center, Japan National Oil Corporation, data acquisition on the ocean and ground can be simulated using models. This system can provide data for verification of the data processing and elastic wave simulation algorithm. This can also provide data for decision of experiment specifications by making a model simulating the underground structure of the given test field. The model used for the physical modeling system is a gradient multilayer model with six-layer structure. Depth migration before stacking was conducted using data obtained through two acquisition methods, i.e., up-dip acquisition and down-dip acquisition. The depth migration before stacking was performed for data obtained by up-dip acquisition in addition to the records obtained by down-dip acquisition. Consequently, a definite reflection surface was observed, which has not been observed from the processing results of down-dip acquisition data. 9 figs.

    The reduction of forests due to environmental pollution has been surveyed, to investigate the pollution-resistant plants and solid microorganisms. In Japan, the blight of needle-leaf trees (pine and momi fir) and of Japanese oak has occurred, and blight of some other trees, such as wild cherry trees, Japanese apricot trees, birch, Japanese cedar, cypress and bamboo, has been reported from various regions. In this article, plants reported to be resistant to pollutants are listed, and the physiological features of these plants are described. Furthermore, to develop pollution-resistant plants, reports relating to clarification of the mechanism of resistance development and the genes involved are reviewed. Microorganisms which symbioses for roots support these root functions. They also suppress the activity of pathogenic microorganisms and improve the environment around the roots, thus helping plants to grow normally. The roles played by symbiotic microorganisms and how to utilize these organisms are discussed. Their functions in coping with acid rain and heavy metal pollution, and how to utilize such functions are also discussed. 707 refs., 13 figs., 13 tabs.

    This paper summarizes the research result in fiscal 1997 from the basic research results on the commercialization of innovative energy technologies. The target of a photovoltaic power generation market includes isolated power sources (several kWp) for distant places or developing countries, and those (several tens kWp) for personal residences or public facilities. Although the former is mainly promoted in the West, while the latter over the world, their profitability is unsolved. Power plants over several hundreds kWp are in demonstration test. Solar heat power generation of several tens to hundreds MWp is most profitable, however, small-scale one is poor in feasibility. Australia takes an interest in distributed photovoltaic power generation directly connected with actual lives of residents, and has a dominant opinion that desert is useless as large-scale site. This country lays emphasis on protection and maintenance rather than positive use of desert based on a basic cognition that desert is easily changed and broken. The Australian government announced power company`s obligation to use renewable energy by 2%, and a strong organization is scheduled to be newly established. 59 figs., 57 tabs.

    As part of the coal hydrogasification technology development survey project, overseas surveys were carried out as in the preceding fiscal year. With an emphasis placed on the process materials and resources, and on product utilization technologies, surveys and studies were conducted about the trends of development of coal and natural gas resources, and information was collected on energy-related matters in Indonesia and Australia. The need of hydrogasification technology was investigated from the viewpoint of natural resources. Moreover, Japanese engineers were dispatched to APEC (Asia-Pacific Economic Cooperation Conference) New Energy Seminar, Indonesia. Visits were made for information on the natural gas resources at an LNG base in East Kalimantan, Indonesia; coal gasification, energy, and others at CSIRO (Commonwealth Scientific and Industrial Research Organization), Australia; coal bed and methane resources at Warren Center, University of Sydney, Australia; coal bed and methane resources at the Brisbane office, Mitsubishi Gas Chemical Company, Inc.; and coal resources at coal mines of Idemitsu South Queensland Coal Pty Ltd.

    This survey aims to verify whether recoverable energies can bear the important role of energy source in place of fossil fuels, to probe into problems that may arise in the process of recoverable energy introduction, and to compile suggestions about measures toward their smooth introduction, these by working out an 'ultralong-term world energy supply and demand outlook' valid up to 2100. Various measures to deal with global warming are analyzed by simulation. The study is not to predict what is in store but to metrically describe and present choices and possibilities for the future with a theoretical consistency based on various factors including economic growth, population, demand for energy, magnitude of fossil energy resources, and feasibility and cost of recoverable energies. This study implies that there is not a single, determining policy for solving the global warming problem and that it is important to cope with the problem by resorting to combinations of various means.

    Importance was studied of making a research on the chemical process technology using the supercritical fluid. As for its effect on global warming, the amount of CO2 emission was compared during the operation between the conventional process and the process using the supercritical fluid, the CO2 reduction rate and amount were trially calculated, and a CO2 reduction of a several ten thousand ton scale in carbon conversion was predicted. As to hazardous materials and the reaction of waste retrieval, it was made clear that the process using the supercritical fluid was valid also for objects for which the chemical process used to be impossible, which indicates a possibility of the widening field of application. Concerning its effect on the energy conservation, energy reduction of several ten thousand tons in heavy oil conversion was predicted by replacing all the existing processes with supercritical fluids. Relating to the recycling, with the use of supercritical fluids, the process is possible which produces higher quality and yield and fewer unnecessary products such as char than the conventional process. 197 refs., 102 figs., 71 tabs.

    The Physical Modeling System introduced into the Technology Research Center, Japan National Oil Corporation, and data collected by use of the system are presented. The Physical Modeling System is 10,000 times smaller than the real one, comprising a water tub section, measuring device section, and control section, etc. The water tub section comprises a tub for housing the model, transducers for transmitting and receiving vibration, controllers, etc. The water tub measures 1.8{times}1.2{times}0.9m. The model used in the experiment is an `inclined multilayer model` with each of its six layers pinching out toward the top, and is usable for the comparison of various migration methods. In one case in the records, reception was made at 184 reception points deployed at intervals of 3mm, when the minimum offset was 15mm and the maximum offset 564mm. Nothing very obvious was observed when the ordinary overlapping of DMO and CDP was applied to this record, which suggests that pre-overlapping migration treatment is required. 5 figs.

    The present paper suggests chief measures to suppress and reduce global greenhouse gases. Under the control of artificial environments such as bioreactor, hydroponics and vegetable factory, a very high fixing rate of CO2 can be obtained, but CO2 generation accompanying electric power consumption is also large. It is preferable to use methane as resource by reforming reactions or selective oxidative reaction. In the recovery technique of fluorocarbon, 100% recovery is desirable. Techniques for decomposing recovered fluorocarbon and converting it to harmless material are the most backward ones. Understanding of essential structural relationship of coal is necessary for establishing combustion technique for the reduction of N2O. The integrated power generation system composed from solid electrolyte type fuel cell and coal-gasifying process, high-performance, superheat pump system form scientific technology imposing no burden on the global environment. Establishment of purification technique for industrial- or living-related drain inflowing to a closed water area system, establishment and reinforcement of inspection system for oil spill in the oceans in a global scale are required. 240 refs., 63 figs., 30 tabs.

    Hydrophilicity results when the surface of titanium dioxide is reduced for the specified oxygen to be replaced by hydroxyl groups. The ease with which such a structural change occurs is subject to variation between titanium dioxide crystal surfaces, and is dependent greatly on the atmosphere. No hydrophilic trend is observed in an atmosphere of oxygen only without moisture and, in darkness without light, hydrophobicity occurs early. Although the contacta angle titanium dioxide with water with stability is not known, yet it is presumed, on the analogy of the case of strontium titanate, that it is in the range of 20-40 degrees. A hydrophilic trend below the range is attrributed to structural changes. The control of surface wettability is one of the basic tasks to fulfill in various kinds of mechanisms and manufacturing processes. The technology of wettability control using a titanium dioxide coating which is quite durable will be applied not only to functions involving defogging, dripproof, and self-cleaning, but also to the control of heat transmission in the mechanism and to the bonding process.

    This paper describes discharge excitation technology and resonator technology as basic technologies for high power CO2 lasers. As a result of progress in high-frequency power element techniques, the discharge excitation technology now generally uses laser excitation using AC discharge of capacity coupling type. Its representative example is silent discharge (SD) excitation. This is a system to excite laser by applying high voltages with as high frequency as 100 kHz to 1 MHz across a pair of electrodes covered with a dielectric material. The system maintains stability in discharge even if power supply voltage amplitude is modulated, and easily provides pulse outputs. Discharge excitation for diffusion cooled type CO2 laser generates a discharge in a gap with a gap length of about 2 mm, and can perform gas cooling by means of thermal conduction of gas, whereas a compact resonator can be fabricated. A resonator for the diffusion cooled type CO2 laser eliminates gas circulation and cooling systems, hence the device can be made more compact. A report has been given that several of these compact resonators were combined, from which a laser output of 85W was obtained by using RF discharge of 2kW. 43 refs., 21 figs.

    This paper compares and explains pieces of communication equipment in high-speed railways in Japan and Europe. The Shinkansen railways in Japan adopted a train wireless communication of the LCX system in 400-MHz band (partly a spatial wave system) that is used for orders, business operations, and public telephone lines, as well as data communications. Almost all of the European countries use the UIC system train wireless communication (the UIC Standard specifies the operation methods, criteria for communication quality assurance, frequency allocation plans, wireless line control systems, and control signals). This paper summarizes the systems adopted in Japan and Europe by the following items: order telephones, data communications, on-board public telephone service, measures against tunnel interference, track-side transmission cabling facilities, and seat reservation systems. The paper indicates that the communication facilities in the Shinkansen railways are distinguished from those for the conventional railway services to meet the requirement of high-speed and large-number conveyance, while the communication facilities in the European high-speed railways are interchangeable with those for the conventional railway lines. 7 figs., 1 tab.

    For the purpose of reducing the geothermal development cost and increasing the amount of developable resource, the paper reviewed the geothermal developmental technology. Approximately 30 MW as a scale per unit is economical. The development cost is lowered by 2% if the period for development is shortened by two years, by 11% if the utilization rate is increased by 10%, and by 3% if the success rate is increased by 10%. The cost is reduced by 10% if the steam amount per 1 pit is increased to 1.5 times, and by 4% if the reduction amount is increased to 1.5 times. Improvement of survey/exploration/evaluation technology and improvement of power generation/management technology contribute largely to making the above possible. The drilling depth also corresponds with increases in the amount of steam obtained and the cost. The construction cost including the drilling cost is also an important factor, indicating a cost reduction of 15% if the unit price is reduced by 20%. If a 30% reduction of the power generation cost at a 30MW plant can be made, a 10 yen/kWh is realized, which shows that a geothermal power plant can be competitive with a thermal power plant. When thinking of it without subsidies, the geothermal power generation is most economical of all the renewable energy. In the light of the environment, the CO2 issue, etc., the geothermal power generation is much more advantageous than the thermal power generation. 7 refs., 28 figs., 8 tabs.

    Described herein are the final evaluation results obtained by the 7-year R and D project, beginning in the FY 1976, established by the national project system for developing the techniques for treating urban solid wastes. This project has developed a semi-wet type selective crushing/sorting unit for sorting the wastes, and established the elementary techniques for recycling the wastes into various products, e.g., compost, pulp, combustible gases, aggregates, methane gas, or fuel oil. Two types of total treating systems, in which these elementary techniques are integrated, have been developed; one is to recover materials and the other energy. They can comprehensively, efficiently treat the wastes, adapting themselves to various situations. Pyrolysis which discharges reduced quantities of flue gases is adopted. Waste water is treated, mainly by biological treatment which is supported by the conventional methods, e.g., coagulation and adsorption. The cost estimation results indicate that the total system developed by this project can compare favorably with the conventional incineration system under general conditions, at a capacity of 300 t/d or more, when taking into consideration the secondary effects brought by the recycling/reutilization. This system is commercially feasible, when it meets with local characteristics, e.g., garbage collecting systems, market values of recycled resources, treatment/disposal conditions, and natural and social environments. This project has sufficiently achieved the original objectives. (NEDO)

    Various latest technical developments were surveyed for the cost-effective installation of power distribution cables under pavements, and their applicabilities were demonstrated with the evaluation of their cost-reduction effects. Cables in conventional vinyl protection tubes could be buried only 30cm under pavements, and in such case, the cost was reduced to 51% of those of conventional methods. As the results of soil tests, excavated soil over 80% was reusable through coarse screening. Underground radar technique to explore buried pipes from the surface was detectable several pipes buried 1.5-2.0m underground, although some problems in precision were found. The improvement of reinforced concrete man-hole structures to minimize the volume of excavated soil indicated the cost reduction of nearly 20%. The application of these techniques to the installation of cables was expected to ultimately halve the total civil engineering cost. 21 refs., 130 figs., 46 tabs.

    This project is aimed at construction of the system which can provide information after searching in realtime key words in a vast volume of reports by Intergovernment Panel on climate Change (IPCC) and answers to Policy Relevant Questions (PRQ). The technical terms appearing in scientific documents use few synonyms to avoid ambiguity, and analysis of frequency of keywords is expected to be an index which provides important information. The chapters in the IPCC reports are not independent but coordinated with each other. It is therefore considered that analysis of the inter-chapter structures based on the keyword frequency analysis provides the meaningful viewpoints for, e.g., understanding Third Accessment Report (TAR) and extraction of the future research themes. For analysis of the logical structures of the sentences containing the keywords, special attention is focused on the term (sustainability) as the most important keyword in TARs, and its logical structures are analyzed. It is decided that the answers to PRQ are extracted from TOD. (NEDO)

    This metal melting system is a process to efficiently melt and regenerate scraps of aluminum, copper and iron by utilizing high-temperature energy obtained from pulverized coal-oxygen combustion. The process is intended to utilize coal in place of petroleum for reduced fuel cost. Joint studies have been carried out as a subsidy operation of the Agency of Natural Resources and Energy with a schedule of six years starting fiscal 1992. Development tests are being performed using a 5-ton/ch pilot plant facility since fiscal 1995 after having gone through experiments using a 1-ton/ch bench scale furnace. This paper reports the results obtained to date. Using the pilot plant facility, fiscal 1995 has achieved the initial target values, such as thermal efficiency of 55% or higher, and yield of 96% or higher for non-ferrous metals and 94% or higher for iron. The melting behavior in the furnace has improved the thermal efficiency as a whole by retaining the conditions in the preheating step for an extended period of time. The thermal efficiency has been improved better than with the bench furnace as a result of upscaling effect. 9 figs., 3 tabs.

    A study was made for the purpose of electrification of unelectrified zones of the mountainous areas in developing countries using extremely small hydroelectric power facilities. The target for this project is a development of a micro hydroelectric power system with a size of about 5kW, which is estimated regarding that 1 village has 80 houses and each house needs electricity of 60W. In the study, the low-head system using a weir of irrigation channels in Subang pref. of West Java state was selected by the evaluation of access, stability of flow rate, natural conditions, etc. The hydroelectric power plant is of a flow-in method in which water is taken from the left bank and is injected/discharged to the downstream of the left bank. As the hybrid complementary power source, hybrid battery with a two-hour charging time at peak and a capacity of 3.5kWh was considered. When estimating the construction cost of the hybrid micro hydroelectric power system and equalizing by durable years, the operational cost per kW is 15 times higher than the benefits which local people receive. It was judged to be difficult to say that the micro hydroelectric power system is economically feasible. It was predicted that the financial profit during the demonstrative test is good, according to a trial calculation of income from power rates and the operational cost. 18 refs., 90 figs., 53 tabs.

    This paper describes technological development at the Kansai Cable Service Company. A momentary voltage drop monitoring system detects momentary power failure at substations in the load system, transmits and aggregates the information at branch offices via control stations. Data are processed into readily identifiable information, and displayed quickly on branch office terminals or at sales offices. In a TV wave reception disturbance survey, the disturbance can be surveyed by utilizing the image quality evaluation characteristics of MPEG2 that can store animated images of good quality in digital data. The SS wireless system consists of a wireless transmission device intended for remote monitoring and image information transmission. The communications distribution frame control system puts terminal information (the number of terminals exceed several hundred thousand depending a case) into a database, and structures a system by using a low-cost general purpose personal computer which can perform information retrieval and terminal table preparation easily in a short time. The system improved the efficiency and accuracy of the control operation. A PHS quasi animated image transmitting system was also developed. A CATV telephone system and a CATV Internet system were investigated and studied as an experimental study on wide-area multi-media service. (NEDO)

    Trimming was performed and studied by cutting KFRP, an epoxy matrix with Kevlar fiber woven thereinto, using various laser beams. The CO2 laser is capable of high-speed cutting but the product is low in quality. The surface of a cut by the YAG laser is not high in quality even with its peak output elevated. The thermally affected area is smaller under the excimer laser but it is low in cutting speed. The ablation properties of the excimer laser were investigated and the beam was shaped into a linear beam for another experiment, but it failed to attain the target speed of cutting. Next, a combination of excimer laser and CO2 laser was used for cutting. It was so designed that the preceding CO2 laser cuts the KFRP at a high speed to leave behind a carbonized layer, which is followed by a linear beam which vaporizes the carbonized layer for removal. An optical system is adopted for reshaping the excimer oscillated beam into a tube-like beam. Optical conditions were determined for a fluence value required for the removal of the carbonized layer. When the CO2 laser was set at 160W and the excimer laser at 20W, a 1mm-thick sheet was successfully cut at a speed of 16.7mm/sec. 3 refs., 7 figs.

Energy conservation technologies in use in Japan's steelmaking, cement making, chemical, and oil refining industries were reassessed in view of their usefulness in the above-said project. During the reassessment, they were analyzed also for cost effectiveness for the scales on which they would possibly be introduced. Ninety-four technologies were reassessed, which involved the top pressure recovery facilities, continuous casting facilities, high frequency melting furnace, and high efficiency sintering furnace ignition device, these for the steelmaking industry; the materials crushing vertical roller mill, NSP (new suspension preheater) type cement calcination kiln, finishing process preliminary crusher, urban wastes conversion into materials for cement making or into fuel, these for the cement making industry; the multi-effect evaporator for an ammonia manufacturing process and the device for collecting waste heat at the outlet of a synthetic gas compressor, these for the chemical industry; and reduction in the amount of injection steam by use of vacuum distillation tower top steam recycling, etc., these in relation with oil refining facilities.

    This survey is intended to discuss the status quo in movements of technologies related to phytoremediation (PM) that utilizes metabolic functions of plants, the overseas situation thereof where the PM application has advanced, and the future technological problems. The PM can be divided largely into the following four categories according to the actions of plants: 1) phyto-extraction - absorbs substances dissolved in water directly or through actions of leguminous bacteria to purify the water or soil; 2) phyto-transformation - action to absorb polluting substances into plant bodies and decompose them; 3) phyto-stimulation - rhizospheric microorganisms are activated by enzymes secreted from roots to decompose chemical substances; and 4) phyto-stabilization - actions to fix or stabilize polluting chemical substances by actions of substances secreted from plants and/or leguminous bacteria in soil and interactions with soil particles. Japan's independent researches have derived such researches as a research to utilize street lining trees to purify polluted air, a research to realize purification of hard-to-degrade substances by introducing degradable genes of microorganisms, and a research intended to create plants that accumulate in them heavy metals densely.

    The recycling technology employed in Tokyo were reported. It will be useful for developing and introducing the recycling technology for water, heat, and sludge in the sewage treatment. Among various kinds of recycling technology, one of the most peculiar technology is the district heating and cooling system using the heat of sewage. The Japan`s first practical plant which uses the untreated sewage as the heat source was installed and is now operating in Korakuen pump station. In the station, the energy contained in the sewage is recovered by a heat exchanger. The heat pump produces warm water of 45{degree}C and cold water of 7{degree}C as well. Both are supplied to the area near by through the heat source supply pipeline. The Nanbu sludge plant has a sludge-resourcing plant, in which the sludge is converted into fuel, metro-bricks, and light-weight granules, as well as a conventional sludge treatment plant carrying out the concentration, dehydration, and incineration of sludge. The Ochiai sewage treatment plant reuses water after cleaning. The clean water is used as for the service water in addition to being discharged into the river stream. 7 figs., 1 tab.

    Japan is one of the most distinguished volcanic country in the world and about 8% of the active volcanos of the world are distributed in Japan. This kind of a large quantity and natural energy resource near us are used as hot springs in the whole country and as for electricity in 10 geothermal power stations. In future, if this enormous underground geothermal energy could be utilized safely and economically by using new power generation system like hot dry rock geothermal power generation (HDR), it may contribute a little to the 21st century`s energy problem of Japan. Central Research Inst. of Electric Power Industry has installed `Okachi HDR testing ground` in Okachi-machi of Akita Ken, and is carrying out experiments since 1989. Hot dry rock geothermal power generation is a method in which water is injected to the hot dry rock and the thermal energy is recovered that the natural rock bed is used as a boiler. However, development of many new technologies is necessary to bring this system in practical use. 9 refs., 5 figs., 1 tab.

    Equisetum was noted as a plant adaptable to stringent environment referred to as the water level varying part of a reservoir, and was used for afforestation trials. The afforestation trials were performed at the reservoir of Uryuu Dam No. 1 and the regulating reservoir of Moiwa Dam of Hokkaido Electric Power Company. Although the rate of water level variation is small at Uryuu Dam No. 1, it is necessary for Equisetum to withstand submergence and drought for an extended period of time. Moiwa Dam has high water level variation rate, but its water depth is small, and the reservoir is free of long-term submergence and drought. As a result of long-term observation from 1993 through 1997, Equisetum was found having grown well at lower altitude part with higher submergence frequency. It has grown favorably even in parts where submergence rate reaches about 80%. However, at higher altitude with submergence rate of 10% or lower, decrement trend was seen. At Moiwa Dam, Equisetum was all buried in accumulated sand and earth, revealing that such an environment is unsuitable for Equisetum as the one subject to effect of sand and earth that flow in during freshet.

    In order to identify the actual status of geothermal reservoirs, development is made on a technology to detect cracks in a geothermal reservoir. This fiscal year has launched development of a PS sonic logging device of well wall compression type, which is considered most effective in crack detection. This device has a number of new development elements such as a mechanism to have a transmitter and a receiver compressed on a geologic stratum to send sonic energy directly into the stratum, simultaneous use of S-wave having excellent characteristics in evaluating crack faces quantitatively and calculating porosities, and a cooling mechanism for electronics installed in the wells. Combining this with a micro seismogram log scheduled to be fabricated in fiscal 1976 will form the mainstream of crack face detection. A continual flow meter measures behavior of steam and hot water to identify flow-out or flow-in patterns and depths of fluid in wells under flowing condition. Adding this meter to temperature and pressure elements scheduled to be developed in fiscal 1976 will provide data to give an important guideline in underground heat production. This meter was attempted with enhancement in heat and pressure resistant characteristics and stabilization of operation for design and fabrication, which were carried out using the spinner flow meter as the base.

    For development of production technologies suitable for environment, safety and advanced information-oriented society by improving the flexibility of production lines, some new measurement technologies were researched. Problem solution was attempted by combining the in-situ multi-dimensional measurement technology capable of easily obtaining various 3-D information with the non-contact photon measurement technology superior in operability and sensitivity under any environment conditions. This solution requires a compact radiation source with higher brightness and wider spectral range, and a high-sensitive detector. The technology concentrating photon onto minute regions, high-efficiency transmission, and control technology of photon wave front are also necessary. Development and international standardization of a common interface is unavoidable. In addition, its network is essential for advanced use of multimedia,. In the future, the comfortable life surrounded by advanced products and multimedia, comfortable social environment, safety and resource saving will be achieved by this technology. 94 refs., 75 figs., 15 tabs.

    Demands for constellation satellites were surveyed and satellite systems were studied for extracting basic technical tasks relative to constellation satellite systems and for drafting space verification plans. For a constellation satellite system to accomplish its missions, two or more satellites have to be simultaneously navigated. It is assumed that its field of application will cover earth observation, information communication, risk management, disaster prevention, and the like. With such applications taken into consideration, surveys and studies were conducted about the need and marketability of constellation satellites, need of state-level involvement, and requests for missions to be imposed on a constellation system. For plural satellites to satisfy mission requests by coordinating with each other, it will be necessary to develop basic technologies, such as navigational guidance, communications control, system autonomous management, and operation on the ground. Functions and performance that a constellation satellite system are requested to have and basic technologies to be studied and developed were extracted, and space verification plans were drafted.

    The paper reported on the research, design, and evaluation on a system to recover by sedimentation magnesium from the brine in the salt manufacture by solar evaporation in Mexico, and a system to recover by adsorbent lithium, boron, etc. from the brine of the solar pond salt field in China. In the case of Mexico, an overall recovery system was developed, but in the evaluation of economy of the system, it cannot be said that the system is feasible even if assuming that the required fresh water can be secured. It was found out that the economical efficiency largely depends upon the cost of hydrated lime and the selling price of magnesia clinker. In the case of China, a plant for production of 500 tons/year of lithium carbonate was conceptually designed to evaluate the economical efficiency. As a result, the internal profitability of the plant is not so high, approximately 6%, though continuously profitable during the operation of 15 years. It was indicated that the project was not economically very efficient. 164 figs., 44 tabs.

    This paper describes a prospect of French industrial technology research and development under President Chirac`s political power. The research and development in France is characterized by the national leadership. It depends greatly on the system and organization as well as the economical factors. The policy concentrates on the reformation of development organization rather than the research and development itself. It is required to provide the cultural and social tradition and environment that can bring up people bearing it, the system that can supply the methods of research and development, and the force of technology and market development that can industrialize and commercialize its results. The national leadership in France basically relates to all of these three factors. The actors of framework for the financing and enforcement of research and development are illustrated in a scheme by dividing them into government and companies. The actors for the enforcement of research and development are also divided into governmental public organizations and companies. This paper also provides the defense development in the private companies having a large finance of research and development from the government. The finance of research and development for public welfare from the government is roughly divided into the large-scale projects with determined usage by the government, and the supports for proposals by the companies. 13 refs., 4 figs., 40 tabs.

    The purposes of this research are to establish large-scale reforestation techniques, and to transfer these techniques into Indonesia for contributing to the preservation of tropical rain forests and the protection of global warming. Lauan trees provide disease and drying resistance properties by inoculating their roots with mycorrhizal fungi, to promote their growth. This is due to the symbiotic relationship between them, in which mycelia of mycorrhizal fungi collect and bring water and nutritive substances in the soil to the roots of lauan trees and intake sugars from the roots as nutrition. Since lauan trees are local variety, they are suitable for the preservation of biosystem. Since their growth life is long, they are suitable for the fixation of CO2. However, the reforestation techniques have not yet been established. Between FY 1992 and 1997, a high survival rate about 60% was obtained through a method in which natural seedlings in mountains were implanted and a method in which seeds were planted in the nursery. About 34000 lauan trees have been planted for the reforestation tests. An inoculation method was established for the accelerated growth of seedlings with mycorrhizal fungi. Through the inoculation, the growth rate was increased up to three times of that without inoculation. The lauan trees grew up to 5 m, and the survival rate was also increased up to twice. 11 figs., 3 tabs.

    The paper studied the solar energy use methanol synthesis using CO2 as raw material in the natural gas field with which a large quantity of CO2 is associated. This is a report on the FY 1999 survey. It was found that comparatively many natural gas fields containing CO2 exist also in Asia/Oceania regions. It was also found that when considering the climate and the transportation to Japan, Australia has more advantages in terms of the effective desert area, etc. and is the best site for solar system construction. Various solar concentrating/collecting methods now under development are roughly viewed to extract characteristics and developmental conditions. As to the reforming reaction furnace, it is necessary not only to absorb the world technology, but to develop Japan's original one. The conceptual design and assessment of the system were conducted. About the associated CO2, a limit of the concentration for use was estimated at 25%. In the study of elements of system structure, examined was the thermally combined simulation of heat flow and chemical reaction in the solar heat reaction furnace, and simple models were calculated and subjects were extracted. In a comparison with the conventional methanol synthesis method, this system was found to be excellent in conservation of fossil fuel resources and reduction in CO2 emissions. (NEDO)

    2014-01-01

    In order to clarify the heterogeneous nucleation potential of α-Ni grains on Ni 3 Si particles in Ni-Ni 3 Si eutectic alloy, the work of adhesion (W ad ), fracture toughness (G), interfacial energy (γ i ), and electronic structure of the index (0 0 1), (1 1 0) and (1 1 1) Ni/Ni 3 Si interfaces with two different cohesive manners are investigated using first-principles method based on density functional theory. Results indicate that the center site stacking sequence (OM) is preferable to continue the natural stacking sequence of bulk Ni and Ni 3 Si. Since OM stacking interfaces have larger W ad , G and γ i than that of the top site stacking (OT) interfaces. The Ni/Ni 3 Si (1 1 0) interface with OM stacking has the best mechanical properties. Therefore, the formation of this interface can improve the stability, ductility and fracture toughness of Ni-Ni 3 Si eutectic alloy. The calculated interfacial energy of Ni/Ni 3 Si (0 0 1), (1 1 0) and (1 1 1) interfaces with OM stacking proves the excellent nucleation potency of Ni 3 Si particles for α-Ni phase from thermodynamic considerations. Besides, the electronic structure and chemical bonding of (1 1 0) interface with OM stacking are also discussed.

    Kimura, Takashi; Itagaki, Yoshio; Wakaya, Fujio; Gamo, Kenji

    2001-01-01

    The dipole interaction between a NiFe layer pinned by a NiO and a free NiFe layer in a micron-wide NiFe/Cu/NiFe/NiO wire was studied by changing the direction of the exchange bias from the NiO layer. The effect of the dipole interaction when the exchange bias was perpendicular to the wire axis was larger than that when the exchange bias was parallel to the wire axis, and was consistently explained by the stray field caused by the magnetic charges of the pinned layer. It was demonstrated that this method, using exchange anisotropy, is useful for investigating the dipole interaction between ferromagnetic materials separated by a nonmagnetic material in small-scale magnetic multilayers.

    Electrochemical reaction of Ni particle, one of active cathode materials in the Na/NiCl2 battery, occurs on the particle surface. The NiCl2 layer formed on the Ni particle surface during charging can disconnect the electron conduction path through Ni particles because the NiCl2 layer has very low conductivity. The morphology and size of Ni particles, therefore, need to be controlled to obtain high charge capacity and excellent cyclic retention. Effects of the Ni particle size on the cell performance were investigated using spherical Ni particles with diameters of 0.5 μm, 6 μm, and 50 μm. The charge capacities of the cells with spherical Ni particles increased when the Ni particle size becomes smaller because of their higher surface area but their charge capacities were significantly decreased with increasing cyclic tests owing to the disconnection of electron conduction path. The inferior cyclic retention of charge capacity was improved using reticular Ni particles which maintained the reliable connection for the electron conduction in the Na/NiCl2 battery. The charge capacity of the cell with the reticular Ni particles was higher than the cell with the small-sized spherical Ni particles approximately by 26% at 30th cycle.

Museums for survey were the following ten: Chiba Museum of Science and Industry; Garasu no Sato (Glass Village); Maizuru World Brick Museum; Museum of Industrial Technology; Numata Memorial Hall/Mitsutoyo Museum of Dimensional Metrology; Omachi Energy Museum; Sake Museum; Saint Juan Bautista Museum; Subway Museum; Textile Museum Yukari. One of the points of this survey was to survey the actual state of the experimental type exhibition. The experimental type exhibition, which is wide in sphere, seems to be effective since visitors can operate it, simulate it, feel its size and make scientific experiments. However, the museums are not necessarily satisfied with the present situation. (NEDO)

    The paper described the results of the survey of the formed raw material field in relation to the FY 1999 long-term energy technology strategy. In the advancing international specialization, efforts are being made for the secure basic base technology force and cost reduction required for competition, and at the same time the aim is not to retain/improve all the formed raw material technologies, but to discriminate the materials in the aspects except the cost. By promoting the reformation into the proposed type industry, it is necessary to work out the bold strategy including the review of the system/structure for promoting the strategic technology innovation by aiming at the important formed raw material technology which can be a life line for the assembly industry, in particular. Concretely, the comprehensive technology system which concentrated a variety of engineering knowledge/information was constructed. The system is shifted to the one that adopted information/communication technology. The conversion in the early time to the proposed type industry is attempted. Japan acquires capability for heightening the level of technology, by which Japan will continue leading the formed raw material technology to the world's top level. Japan realizes the network consisting of the industry, university and government. The environment is realized where new personnel will naturally enter the formed raw material industry and bottom up the total technology force. (NEDO)

    This report summarizes the fiscal 1999 basic research result on industrial technology strategy of a machine tool field. Corresponding to construction of an environment-friendly recycling economic society and economic growth as estimated change in social and industrial structure during 2010-2025, major themes are reuse of machine tools, energy saving, environment design, chip treatment and resource recovery. With preparation of information infrastructures in an advanced information society, major issues are 3D-CAD, remote diagnosis, remote control and self-restoration. Because of decline of the birth rate, positive employment of aged persons and women is desirable. New machining technology for new materials, and fusion of various machining technologies are important. For micro-technology, study should be made on the concept and effect of micro-factory (energy saving, space saving, cost reduction, higher accuracy and higher speed). For higher-accuracy machine tool, static, dynamic, thermal and movement characteristics are the key for improving the proper technology. For faster machining. fine basic structural element, faster main spindle and faster feed are important. (NEDO)

    Described herein are the FY 2000 results of the survey on the technological trends of utilizing the reactions with metals in a living body, noting the bio-processes effectively coping with the environmental problems. The effects of heavy metals on microorganisms have been investigated on the molecular biology level, but are not fully elucidated. Recently, the microorganisms capable of converting inorganic metal ions in water into the insoluble compounds have been known, leading to possibility of bioremediation to solve pollution by heavy metals, which have detrimental effects on human health. Heavy metals must be recovered, because they are not extinct by decomposition. The plant aided purification has been attracting attention to cope with heavy metals accumulated in soil. Application of bacteria-aided leaching, which is adopted as one ore smelting process, to the technologies for utilizing metals in a living body has been expected, because diversified activities of inanimate matters in extreme environments have been known. Recently, bio-machining of metals aided by Thiobacillus ferrooxidans, one species of independent nutrient bacteria capable of eating metals, has been developed to a potentially viable stage. (NEDO)

    One dimensional (1-D) motion of interstitial clusters is important for the microstructural evolution in metals. In this paper, the effect of 2 at.% alloying with elements Si (volume size factor to Ni: -5.81%), Cu (7.18%), Ge (14.76%) and Sn (74.08%) in Ni on 1-D motion of interstitial clusters and void growth was studied. In neutron irradiated pure Ni, Ni-Cu and Ni-Ge, well developed dislocation networks and voids in the matrix, and no defects near grain boundaries were observed at 573 K to a dose of 0.4 dpa by transmission electron microscopy. No voids were formed and only interstitial type dislocation loops were observed near grain boundaries in Ni-Si and Ni-Sn. The reaction kinetics analysis which included the point defect flow into planar sink revealed the existence of 1-D motion of interstitial clusters in Ni, Ni-Cu and Ni-Ge, and lack of such motion in Ni-Si and Ni-Sn. In Ni-Sn and Ni-Si, the alloying elements will trap interstitial clusters and thereby reduce the cluster mobility, which lead to the reduction in void growth.

    A model system consisting of Ni[001](100)/Ni 3 Al[001](100) multi-layers are studied using the density functional theory in order to explore the elastic properties of single crystal Ni-based superalloys. Simulation results are consistent with the experimental observation that rafted Ni-base superalloys virtually possess a cubic symmetry. The convergence of the elastic properties with respect to the thickness of the multilayers are tested by a series of multilayers from 2γ'+2γ to 10γ'+10γ atomic layers. The elastic properties are found to vary little with the increase of the multilayer's thickness. A Ni/Ni 3 Al multilayer with 10γ'+10γ atomic layers (3.54 nm) can be used to simulate the mechanical properties of Ni-base model superalloys. Our calculated elastic constants, bulk modulus, orientation-dependent shear modulus and Young's modulus, as well as the Zener anisotropy factor are all compatible with the measured results of Ni-base model superalloys R1 and the advanced commercial superalloys TMS-26, CMSX-4 at a low temperature. The mechanical properties as a function of the γ' phase volume fraction are calculated by varying the proportion of the γ and γ' phase in the multilayers. Besides, the mechanical properties of two-phase Ni/Ni 3 Al multilayer can be well predicted by the Voigt–Reuss–Hill rule of mixtures. (classical areas of phenomenology)

    The production of large quantities of high specific activity 63 Ni (>10Ci/g) requires both a highly enriched 62 Ni target and a long irradiation period at high neutron flux. Trace impurities in the nickel and associated target materials are also activated and account for a significant fraction of the discharged activity and essentially all of the gamma activity. While most of these undesirable activation products (mainly transition metals) can be easily removed as chloride complexes during anion exchange, chromium, present as 51 Cr, and manganese, present as 54 Mn, are exceptions and require solvent extraction of the in-cell product to achieve the desired purity. In addition to summarizing the current development and production experience, optimized flowsheets are discussed

    The INDRA multidetector allowed us to study the Ni+Ni collisions at 32A MeV and the Ni+Au collisions at 52,4 MeV. Central collisions leading to 'quasi-fused' systems were isolated using multidimensional analysis techniques: the Discriminant Analysis and the Principal Component Analysis. Comparison with a statistical model shows that the selected events are compatible with thermodynamical equilibrium. The average thermal excitation energy is 5A MeV for both systems. Calculations of heat capacities show that the deexcitation of the hot sources are akin to a liquid-gas phase transition of nuclear matter. Indeed heat capacities exhibit a negative branch as expected for a phase transition of a finite system. The dynamics of this phase transition has been investigated by applying the charge correlation method. An enhanced production of events with equal-sized fragments has been evidenced for Ni+Au at 52A MeV. No signal was found for Ni+Ni at 32A MeV. Finally this method was improved by taking into account the total charge conservation. The signal is seen more clearly for Ni+Au at 52A MeV, but is ambiguous for Ni+Ni at 32A MeV. The path followed in the state diagram, or the involved time scales, seem to be different for these systems. (authors)

    In a series of experiments, we have reinvestigated the decay of the doubly magic nucleus 56 Ni, which is believed to be copiously produced in supernovae. We have confirmed its previously known decay scheme and half-life, and have searched for several rare decay modes. We establish an upper limit of 5.8x10 -7 for the branching ratio of the second forbidden unique β + decay to the 158-keV level in 56 Co, leading to a lower limit of 2.9x10 4 yr for the half-life of fully ionized 56 Ni nuclei in cosmic rays. We also establish an upper limit of 5.0x10 -3 for the branching ratio of the isospin forbidden Fermi electron capture transition to the 1451-keV level in 56 Co, which in turn leads to an upper limit of 124 keV for the isospin mixing Coulomb matrix element of the 56 Ni ground state

    A new dinuclear complex (NiC(5)H(4)SiMe(2)CHCH(2))(2) (2) was prepared by reacting nickelocene derivative [(C(5)H(4)SiMe(2)CH=CH(2))(2)Ni] (1) with methyllithium (MeLi). Good quality crystals were subjected to a high-resolution X-ray measurement. Subsequent multipole refinement yielded accurate description of electron density distribution. Detailed inspection of experimental electron density in Ni···Ni contact revealed that the nickel atoms are bonded and significant deformation of the metal valence shell is related to different populations of the d-orbitals. The existence of the Ni···Ni bond path explains the lack of unpaired electrons in the complex due to a possible exchange channel.

Ni nanoparticles with an average size of 8 nm were prepared by dc - arc discharge in argon atmosphere. A current of 130 A and 300 milli bar pressure of argon have been applied. The produced Ni nanoparticles were annealed for oxidizing in air at 350 for six hours to produce antiferromagnetic NiO particles. The structure of Ni and NiO nanoparticles and size estimation of them studied by means of X-ray diffraction. The size and morphology of the particles were also characterized by high resolution transmission microscopy (TEM). The Ni core NiO shell structure, resulting from the oxidation process, were studied by magnetic properties measurements. A quantum design squid magnetometer, model MPMS5S was used for measuring saturation magnetization of both nanoparticles of Ni with and without NiO layer. By knowing the density of Ni and NiO, we were able to deduce the thickness of the Ni core and NiO outer layer. They are around 3 and 5 nanometers respectively. (authors)

    As to long-term energy technology strategy, the paper described the results of the FY 1999 survey of chemical/process technology. The future chemical technology should be transformed from the material production technology in which priority used to be given to convenience to new chemical technology in which the functions needed are to be created. The shortage of the developmental period and minimization of the waste are also desired by the use of new methods. For it, the industry/government/university should gather wisdom together and fulfil the requests from other industries of the country under the circumstances of the society which is aging, is decreasing in birthrate, and is being highly information-oriented. At the same time, the technology should be contributional to constructing the circulating type society which has environmental harmony. If not, it cannot be the technology which is recognized by the society. Efforts should be made for the fundamental technology development, technology to create the materials needed in the society, and development of new process technology to be recognized in the society. Further, the development of technology to meet the needs/restraints from the society should be promoted as seen in the environmental hormone. At the same time, the intellectual base should be prepared such as arrangement of the technology database for advancing smooth technology development. (NEDO)

    The R and D were carried out on a system by which the long life of coolant of machine tools can be achieved and a system to process waste efficiently, economically and with less environmental loads, and the FY 2000 results were summed up. In the R and D of a system to prevent degradation of low energy coolant, measurement was made of effects of the degradation prevention system at a laboratory level, and it was found out that propagation of bacteria causing the degradation can be prevented with pH kept high. Further, it was admitted that the alkali effect on metal formability was not very much. As to the coolant processing, in the present situation, most of the coolant is taken back by industrial waste processing dealers. So, the development of the low energy waste liquid processing system is earnestly desired. In the R and D of the low energy waste liquid processing system, test on characteristics evaluation was conducted about each method of systems. Subjects to be improved/solved were extracted such as the point that volatile organic matters are included in condensed water after evaporation of waste liquid and there seems to be a possibility of needing the secondary processing.

  7. Exclusive study of Ni+Ni and Ni+Au central collisions: phase coexistence and spinodal decomposition

    The INDRA multidetector allowed us to study the Ni+Ni collisions at 32A MeV and the Ni+Au collisions at 52,4 MeV. Central collisions leading to 'quasi-fused' systems were isolated using multidimensional analysis techniques: the Discriminant Analysis and the Principal Component Analysis. Comparison with a statistical model shows that the selected events are compatible with thermodynamical equilibrium. The average thermal excitation energy is 5A MeV for both systems. Calculations of heat capacities show that the deexcitation of the hot sources are akin to a liquid-gas phase transition of nuclear matter. Indeed heat capacities exhibit a negative branch as expected for a phase transition of a finite system. The dynamics of this phase transition has been investigated by applying the charge correlation method. An enhanced production of events with equal-sized fragments has been evidenced for Ni+Au at 52A MeV. No signal was found for Ni+Ni at 32A MeV. Finally this method was improved by taking into account the total charge conservation. The signal is seen more clearly for Ni+Au at 52A MeV, but is ambiguous for Ni+Ni at 32A MeV. The path followed in the state diagram, or the involved time scales, seem to be different for these systems. (authors)

    Embedded Atom Method (EAM) potentials have been developed for the Ni/Al/H system. The potentials have been fit to numerous properties of this system. For example, these potentials represent the structural and elastic properties of bulk Ni, Al, Ni 3 Al, and NiAl quite well. In addition the potentials describe the solution and migration behavior of hydrogen in both nickel and aluminum. A number of calculations using these potentials have been performed. It is found that hydrogen strongly prefers sites in Ni 3 Al that are surrounded by 6 Ni atoms. Calculations of the trapping of hydrogen to a number of grain boundaries in Ni 3 Al have been performed as a function of hydrogen chemical potential at room temperature. The failure of these bicrystals under tensile stress has been examined and will be compared to the failure of pure Ni 3 Al boundaries. Boundaries containing a preponderance of nickel are severely weakened by hydrogen. In order to investigate the potential embrittlement of γ/γ' alloys, trapping of hydrogen to a spherical Ni 3 Al precipate in nickel as a function of chemical potential at room temperature has been calculated. It appears that the boundary is not a strong trap for hydrogen, hence embrittlement in these alloys is not primarily due to interactions of hydrogen with the γ/γ interface

    Experiments were conducted on laser-aided decomposition and removal of chemical substances in liquid phase systems on the assumption that there existed chemical pollutants in wastewater or water after washing burned ash. The aim of the research was to split carbon-chlorine bonds and break benzene rings, the two being the cause of harmfulness, and experiments were conducted using chlorophenol. The photolytic lasers were ArF excimer laser and KrF excimer laser. It was found that the reduction rate of chlorophenol in a water solution under excimer laser irradiation was 1.7 times higher under KrF laser than under ArF laser. For mediums other than water, isopropanol was used, more convenient than chlorophenol in separating organic pollutants from burned ash and the like. In this case, organochlorine compounds were generated at the beginning, but they disappeared when irradiation was prolonged. It was demonstrated that the laser-aided environmental cleaning technology would find a very wide scope of application as an effective photolytic means. (NEDO)

    A survey is conducted about highly automated machines such as industrial robots. The task to be subjected to development as derived from a survey conducted about needs is the construction of a dangerous work robot. It is pointed out that work in coal mines, tall buildings, industrial complexes, or nuclear power plants may encounter large-scale accidents, and the task is how to perform such work in an automated way. The tasks concluded to be subjected to development after a seed survey analysis are categorized into three groups of element technologies, namely, sensors and recognition function, mechanism and materials, and control and data processing. These element technologies are to be ultimately integrated into a robot, for critical work which is a combination of a highly intelligent robot main body and an integrated management system. Since it will happen that humans have to directly operate such a robot under delicate conditions and share the burden of judgement and thinking, it is also necessary to develop technologies to solve problems of man-to-robot engineering. It is proposed that a dangerous work robot research and development program be established before development is started. (NEDO)

    This paper describes the achievement in relation with the mine waste water treatment technology utilizing biomass, from among the promotion projects for research cooperation with China. Waste water is converted into ferric iron (Fe{sup 3+}), which precipitates at low pH, by utilizing iron oxidizing bacteria which use ferrous iron (Fe{sup 2+}) in the waste water as the energy source, and is precipitated and removed by using low-cost calcium carbonate as a neutralizing agent. Fiscal 1998 has performed eight site surveys with 47 persons in total. The main survey items are the study and guidance of pilot plant operation and the survey on measures to prevent occurrence of contamination by heavy metals in Wushan Mine. Additional site surveys were made at Dexing Mine and Yinshan Lead/Zinc Mine. Continued from fiscal 1997, consumables required for the pilot plant were purchased, and items of the bench-scale testing equipment used by Japan for domestic researches (an oxidation and neutralization testing equipment and a copper recovering and testing equipment) were transported to China. The operation research data of the pilot plant were put in order and analyzed. This paper summarizes the concept design of the shaft waste water treatment facilities for the north mine in Wushan Mine, and the surveys on measures for heavy metal contamination sources. (NEDO)

    The purpose of this research is to clarify the application condition and effectiveness of high-temperature CO2 fixation and utilization technology. To evaluate the present process, it was compared with others, such as separation using a polymer membrane, physico-chemical absorption process, adsorption process, hydrogen contact reduction process, and biological fixation. The development trends of absorption, membrane, adsorption, and cryogenic separation were investigated. The questionnaire was carried out about the separation technologies which are in the stage of performance test using actual gas, to arrange and compare the data and information. The current trends of chemical and biological CO2 fixation and utilization technology were also investigated for arranging the subjects. High-temperature CO2 disposal by the carbonation in concrete waste has been studied, to clarify its application conditions and effectiveness. In order to compare the separation technologies, treatment processes of CO2 in the exhaust gas from boilers of LNG power generation and coal fired power generation were simulated. These processes were simulated by ASPEN PLUS for the modeling. Trends of application of ASPEN PLUS and collection of information were surveyed by participating in the ASPEN WORLD. 103 refs., 51 figs., 55 tabs.

    In this study, samples were surveyed and collected of the present regulations and standard, disaster accident, basic literature, etc. concerning the safety of hydrogen in Japan and abroad. Further, according to the necessity, these collected data were translated. The data to be examined/collected are those in and after 1950, and the data except the above-mentioned are collected if those are thought to be important. As to the condition of hydrogen to be examined/surveyed, those under all conditions from gas (normal pressure) to liquid and solidified hydrogen. The data for survey were classified into law/standard, corporate standard, samples of disaster accident, and general literature. The general literature was classified into general physical property, material relation, fire/explosion, and harmfulness/environment. The number of the disasters collected is 81, from which 3 in relation to suffocation and handicap were excluded. The rest is related to fire/explosion and burst. Most accidents occurred at plant or on corporate side, however, it is worthy of note that accidents occurred during the charge of buttery and with advertising balloon or balloon. (NEDO)

    The Japanese government is conducting the training on the CCT downstream field for the persons concerned in the CCT utilization field in the APEC region, especially in nations as new comer into the CCT utilization field where the coal consumption is expected to rapidly increase (China, Indonesia, Thailand, and the Philippines). The demand for CCT diffusion/education to the persons concerned in coal utilization in the APEC region is increasing from each country, and the CCT diffusion/education is becoming a more and more important issue. Accordingly, for the purpose of increasing the understanding of CCT and improving the ability of the persons concerned in APEC countries, the paper surveyed and arranged the environmental protection technology out of the CCT technical information of Japan, and inputted the results into CD-ROM. The results are planned to be used for the understanding of Japan`s advanced CCT and ability improvement in the CCT training course to be planned for managers and engineers from APEC countries. The CD-ROM includes the coal combustion flue gas related technologies such as desulfurization technology, denitrification technology and dust collecting technology which are the environmental protection technology out of the coal utilization technologies in Japan

    The research cooperation project on a technology to treat well waste water by utilizing biomass has used as the object the well waste water from the north mine in the Wu Shan mine in Jiangxi Province. The research included surveys on properties of the well waste water from the subject mine by means of the site survey, discussions on treatment conditions based on studies in Japan, and discussions on factors for designing a full size facility as a result of pilot plant operation research. The Japanese side has transported to Beijing the bench-scale testing equipment used for the studies in Japan (an oxidation and neutralization testing equipment and a copper recovery testing equipment). In the present follow-up project, supports were provided to the research and development activities performed voluntarily by the Chinese side by using the above bench-scale testing equipment through guiding the tests at the site and supplying consumables. Certain bacteria have capability to oxidize ferrous ions in the mine well waste water into ferric ions. Utilizing these bacteria results in sedimentation of iron oxides in lower pH zones than in the conventional method, making removal of heavy metals from the well waste water possible. As a result, such effects may be expected as reduction in chemical cost, and reduction of quantity of the produced sediments. (NEDO)

    In order to decide measures for introducing new energy to the society, the work starts from the investigation of the present state of energy demand, examining feasibility of introducing new energy into the state, and then assuming concretely the circumstances in which new energy is brought into the society to some extent. In the subject research, with 1990 set as a target year, the following examinations are carried out for the purpose of estimating the state of introducing new energy to the Japanese society at such point in time. (a) Feasibility is studied of substituting with new energy on oil users' part at present, with an estimate made on the state of new energy introduction in fiscal 1990. (b) An energy flow analysis is made for the purpose of checking interrelation between the total energy demand structure in Japan and the quantity of introducing new energy as of 1990. (c) On the basis of these results, current various energy-related laws and regulations are reviewed, with policies examined for introducing and promoting new energy. (d) On-site investigation is conducted on relationship with the energy policy of coal producing countries, in the case where a coal liquefaction plant is constructed in such countries and where overseas operations and imports of liquefied oil production are implemented.

    This research cooperation promotion project was implemented to develop techniques for preventing water pollution by waste water from pits in mines in China and thereby contributing to environmental preservation by studying to select optimum bacteria, culture the bacteria for high-efficient oxidation of iron, efficiently remove heavy metals from waste water, develop waste water treatment techniques with the aid of the iron-oxidizing bacteria, suitable for the mines in China, and develop techniques for recovering useful resources. The bio-aided waste water treatment process is a suitable method for treating waste water discharged from mining pits, in which ferrous iron present in waste water is oxidized with the aid of iron-oxidizing bacteria growing with ferrous ion as the energy source into ferric iron, which is precipitated at a low pH and removed in the presence of inexpensive calcium carbonate as the neutralizer. The pilot plant has been operating smoothly in a mode to treat waste water discharged from mining pits in Wushan Mine, almost satisfying the targets of treated water properties, i.e., pH: 0.5 or less, Cu: less than 0.5, Zn: less than 2.0, Pb: less than 1.0, Cd: less than 0.1, As: less than 0.5, Mn: less than 2.0, and SS: less than 70, all in mg/L except for pH.

    With an objective to select a promising process by comparing application environments and effectiveness of a high-temperature carbon dioxide separation, recovery and re-utilization technology with other methods, investigations were performed on reducible amount of carbon dioxide discharge by using material balance and system introduction. A large number of chemical and physical technologies are being developed for the separation and refining methods. This paper discusses the technologies for their application to iron and steel making, oil refining, and petrochemical industries, the so-called heavy and large product industries. As a possibility of utilizing the high-temperature separated CO2 in iron and steel making, an investigation was given on the direct iron ore smelting reduction process. It would be unreasonable to use CO2 in oil refining as a substitute to air to regenerate a catalytic decomposition and reformation catalyst because of decline in the catalytic activity. A discussion was given on a case to replace steam with CO2 in steam reformation and pyrolysis of hydrocarbons. The discussion requires the objective to be focused on such items as C/H ratio at a reformer outlet and relationship of balance in decomposition products. The C1 chemical and others were reviewed to search possibilities for their use as raw materials of chemicals used in chemical industries. Possibilities were discussed to fix high-temperature CO2 into peridotite and serpentine. 42 refs., 32 figs., 11 tabs.

    In order to discuss the ways the Japanese universities should be in venture incubation and for IT industries, and taking measures thereon, surveys have been performed on the current status of the roles played by universities for the information industries in the U.S. as well as trends and measures taken therein. The problem that the U.S. universities are facing is that the superiority of learning in business schools has become more indistinct than in experiencing and learning the business in venture companies. As a result, the number of people who want to enter business schools is decreasing. Therefore, universities are executing audacious innovations including reorganization of the curriculums. Representative examples are the UCLA's entrepreneurship program combining the electric engineering department and the business school, and the Stamford University's marketing skill development course for engineers.

    A field survey was conducted with the aim of commercializing innovative energy technology in the Tibet district. The survey included the energy supply/demand situation and supply plan and the situation of new energy utilization in the Tibet district. And, based on the concrete circumstances in the Tibet district, a realistic plan was presented for solution to the energy supply/demand problem. To carry out the project, used are a lot of solar energy and wind power energy resources which are abundant in Tibet. In about 5 years, 100 sets of village use system and 80,000 sets of household use system are to be installed, which solves the problem on electric power demand in a part of the non-electrified houses. Accordingly, farmers/stockbreeders living in the non-electrified region will alter their life patterns which are closed and behind other countries, get out of the poverty, basically enhance the quality of life, promote the communication of various knowledge/information of scientific technology, renew their life/production concepts, and heighten the production efficiency for the wealthy society. The project itself belongs to the construction for protection of ecological environment. It produces no exhaust gas/solid waste which do harm to the environment. The ecological environment efficiency is very high. (NEDO)

    Effects of Ni vacancy, Ni antisite in Al sublattice, Cr in Al sublattice, Pt in Ni sublattice on the second-order elastic constants (SOECs) and third-order elastic constants (TOECs) of the B2 NiAl have been investigated using the first-principles methods. Lattice constant and the SOECs of NiAl are in good agreement with the previous results. The brittle/ductile transition map based on Pugh ratio G/B and Cauchy pressure Pc shows that Ni antisite, Cr, Pt and pressure can improve the ductility of NiAl, respectively. Ni vacancy and lower pressure can enhance the Vickers hardness Hv of NiAl. The density of states (DOS) and the charge density difference are also used to analysis the effects of vacancy, Ni antisite, Cr and Pt on the mechanical properties of NiAl, and the results are in consistent with the transition map. © 2014 Elsevier Ltd.

    To avoid some of the errors inherent in a quantitative interpretation of shrinkage of powder compacts as Mo-Ni, other experiments were looked for, where the influence of Ni on the material transport properties of Mo could be measured semi-quantitatively during heating up to temperature and subsequent isothermal annealing. The bending of thin Mo foils under small loads was found to be an experimental arrangement, where variations in stress, in Ni-concentration and in intrinsic material properties could be realized. The results of these creep experiments will be compared in a qualitative sense with sintering experiments in Mo-Ni done under similar conditions as the creep experiments

    The Ni-P/Zn-Ni compositionally modulated multilayer coatings CMMCs were electrodeposited from a single bath by switching the deposition current density. The corrosion resistance of the deposits was studied and compared with that of monolayers of Ni-P and Zn-Ni alloys via Tafel polarization, EIS and salt spray tests. Characterization of corrosion products by means of EDS and XRD revealed more details from the corrosion mechanism of the monolayers and multilayers. The corrosion current density of Ni-P/Zn-Ni CMMCs were around one tenth of Zn-Ni monolayer. The CMMC with incomplete layers performed lower polarization resistance and higher corrosion current density compared to the CMMC with complete layers. The electrical circuit that was proposed for modeling the corrosion process based on the EIS spectrum, proved that layering reduces the porosity and consequently improves the barrier properties. Although, layering of Zn-Ni layers with Ni-P deposits increased the time to red rust in salt spray test, the time for white rust formation decreased. The corrosion mechanism of both Zn-Ni and Ni-P (containing small amount of Zn) was preferential dissolution of Zn and the corrosion products were comprised of mainly Zn hydroxychloride and Zn hydroxycarbonate. Also, Ni and P did not take part in the corrosion products. Based on the electrochemical character of the layers and the morphology of the corroded surface, the corrosion mechanism of multilayers was discussed.

    2008-01-01

    A centrifugal combustion synthesis (CCS) process has been investigated to join a Ni-Al intermetallic compound and a Ni-TiC cermet. The cermet, a tubular graphite mold, and a green compact of reactants consisting of Al, Ni and NiO were set in a centrifugal caster. When the combustion synthesis reaction was induced in the centrifugal force field, a synthesized molten Ni-Al alloy flowed into the graphite mold and joined to the cermet. The soundness of the joint interface depended on the volume percentage of TiC phase in the cermet. A lot of defects were formed near the interface between the Ni-TiC cermet and the cast Ni-Al alloy when the volume percentage of TiC was 50% or higher. For this kind of cermet system, using a functionally graded cermet such as Ni-10 vol.%TiC/Ni-25 vol.%TiC/Ni-50 vol.%TiC overcame this difficulty. The four-point bending strength of the joined specimen consisting of the three-layered FGM cermet and cast Ni-29 mol%Al alloy was 1010 MPa which is close to the result for a Ni-29 mol%Al alloy specimen

    The constant flow stress reached during uniaxial deformation of electrodeposited nanocrystalline Ni reflects a quasi-stationary balance between dislocation slip and grain boundary (GB) accommodation mechanisms. Stress reduction tests allow to suppress dislocation slip and bring recovery mechanisms into the foreground. When combined with in situ X-ray diffraction it can be shown that grain boundary recovery mechanisms play an important role in producing plastic strain while hardening the microstructure. This result has a significant consequence for the parameters of thermally activated glide of dislocations, such as athermal stress and activation volume, which are traditionally derived from stress/strain rate change tests

    Chemical synthesis coupled with a microwave irradiation process allowed for the control of size (6-40 nm), shape, and shell thickness of Ni/NiO core/shell nanoparticles. In this unique synthetic route, the size of Ni nanoparticles (NiNPs) was strongly influenced by the nickel salt-to-stabilizer ratio and the amount of the stabilizer. Interestingly, it was observed that the shape of the nanoparticles was altered by varying the reaction time, where longer reaction times resulted in annealing effects and rupture of the stabilizer micelle leading to distinct shapes of Ni/NiO core/shell nanostructures. Product cooling rate was another important parameter identified in this study that not only affected the shape, but also the crystal structure of the core/shell nanoparticles. In addition, a simple and cost-effective method of microwave irradiation of NiNPs led to the formation of distinctly shaped hollow NiO nanoparticles. These high surface area core/shell nanoparticles with well-controlled morphologies are important and can lead to significant advancement in the design of improved fuel cells, electrochromic display devices, and catalysis systems.

    The operation of a 1t/d PSU (process support unit) was studied for the NEDOL coal liquefaction process. In the modification of facilities, equipment and devices were procured for the product oil reforming facilities and their installation was partly accomplished. In the coal injection operation, a 60-day slurry operation was conducted, using coal types of the upper limit and lower limit qualities, for expanding the scope of coal types applicable to the NEDOL process and for exploring optimum conditions, and another operation of 37 days was conducted using Chinese coal and Chinese-prepared liquefaction catalysts, and the two operations were studied for difference in yields and in operationality. Characteristics of the liquefaction reactors were investigated and basic studies were made relative to the physical property of the yielded coal oil. In the operation for maintenance, the 1st liquefaction reactor was singly operated for an 8-day slurry operation, which was to check the progress of liquefaction in a 1-reactor setup. Concerning the reforming of the product oil, the hydrogenation reactors were checked for their response to temperature control. Moreover, hydrogenation solvents were produced for the PSU and for China. (NEDO)

    This project is aimed at surveys on the elementary and peripheral techniques necessary to construct the systems, with the objective to draw the conceptual designs of the total system for co-production of a substance and electric power. In a general reaction process, substances are produced under an advantageous condition that is dependent on reaction rate and equilibrium, where most of the energy is dissipated in the form of sensible and latent heat without being used for the chemical reaction. The co-production system under consideration uses high temperature of 500 degrees C or higher exhausted from a power station or industrial unit to produce macromolecules or synthesis gases, wherein the exothermic reaction increases temperature of the heat source, which is recovered in the form of steam for driving the steam turbine to produce electric power. On the other hand, low-temperature waste heat of around 150 degrees C is converted into a liquid fuel or other value-added products by the liquid phase pressurized system. The elementary techniques to construct these processes are surveyed, and the thermal processes are analyzed. The investigated items include substance production processes, electric power production processes and total systems. (NEDO)

    An investigational study was conducted of applicability/viability of the technology to recycle as resource the organic waste and CO2 discharged from the chemical industry, etc., and the FY 1999 results were summarized. As to the production of hydrogen from the organic waste, a bioreactor was developed which enables the production of hydrogen of 58 mmol/L/hr using Enterobactor aerogenes by the isolation bacteria method, and it successfully enabled the production of hydrogen from biomass resource. Further, the micro-flora method can be responded to a variety of substrates, but in this method the hydrogen production rate is not as high as in the isolation bacteria method at the present time. Concerning the method to convert CO2 to useful organic resource by the hydrogen produced, an experimental value of the maximum production rate of 149g/L/d which is high was obtained in case of acetic acid. Moreover, the paper described an outline and the basic concept of the recycle system of energy and carbon resource which integrates the production of energy from organic waste being considered at the present time and the production of useful matters from CO2.

    As for the collection of sensible heat, 1/3 of blast-furnace slag is treated to the purpose at the Teesside Technology Centre, Britain, but none is collected in the latter half of tapping in case there is so much slag that cooling cannot be done in time. In the case of a large blast furnace, some measures have to be contrived because molten iron comes out of the furnace intermittently. In Germany, the heat collection rate is as low as 3%, with no effort made at heat collection. In North America, desire to develop such a technology is not strong. A visit was made to the Institute of Ocean Sciences, Canada, in relation to the concept of using steel slag as a eutrophic source for marine photo-plankton. A large-scale long-term test is under way for examining the relationship between global warming and ocean current circulation. There are possibilities that Japan will enter into the project for a joint study, for example, of heavy metal elution from slag though the test fails to name slag as the direct object of study. Not only for Canada but also for any other country who faces the sea, it may be a meaningful national policy to inject some active ingredients into the sea for an increase in living marine resources. Greece is engaged in the ocean dumping of nickel slag on an experimental basis but, in view of the purpose of the experiment, Japan will not be a participant in the project. (NEDO)

    This paper describes research on peripheral technologies for hydrogen. For the cost of manufacturing hydrogen from different primary energies, coal gasification could be the lowest at the present time. In the nuclear power field, the thermo-chemical method and the water electrolysing method may be assumed, but they depend greatly on future technological development. Particularly the water electrolysing method is dependent on electric power cost. In the hybrid method, hydrogen is obtained from electrolysing reaction with water of sulfur dioxide derived by paralyzing sulfuric acid (oxygen is also generated). The method requires two forms of energies, heat and electric power, whereas combination with a very high temperature reactor (VHTR) is being discussed as a heat source. This method may not be said greatly more advantageous than the direct water electrolysis, but may have future possibility. Hydrogen manufacturing utilizing living organisms is an interesting matter in terms of science and engineering, with a large number of research achievements beginning to appear. Expectation is drawn on the mechanism based on co-work of photosynthesis and a hydrogen generation system, alga and bacterium strain search, separation, cultivation, and applied research and development. Research is also under way to obtain hydrogen by converting photo-energy by using an electrochemical photo-cell utilizing semiconductor electrode to electrolyse water (color sensitizing) (NEDO)

  11. Water dissociation on Ni(100) and Ni(111): Effect of surface temperature on reactivity

    International Nuclear Information System (INIS)

    Seenivasan, H.; Tiwari, Ashwani K.

    2013-01-01

    Water adsorption and dissociation on Ni(100) and Ni(111) surfaces are studied using density functional theory calculations. Water adsorbs on top site on both the surfaces, while H and OH adsorb on four fold hollow and three fold hollow (fcc) sites on Ni(100) and Ni(111), respectively. Transition states (TS) on both surfaces are identified using climbing image-nudged elastic band method. It is found that the barrier to dissociation on Ni(100) surface is slightly lower than that on Ni(111) surface. Dissociation on both the surfaces is exothermic, while the exothermicity on Ni(100) is large. To study the effect of lattice motion on the energy barrier, TS calculations are performed for various values of Q (lattice atom coordinate along the surface normal) and the change in the barrier height and position is determined. Calculations show that the energy barrier to reaction decreases with increasing Q and increases with decreasing Q on both the surfaces. Dissociation probability values at different surface temperatures are computed using semi-classical approximation. Results show that the influence of surface temperature on dissociation probability on the Ni(100) is significantly larger compared to that of Ni(111). Moreover, on Ni(100), a dramatic shift in energy barrier to lower incident energy values is observed with increasing surface temperature, while the shift is smaller in the case of Ni(111)

    This work deals with the synthesis, processing and characterization of NiO/Ni- CGO composite materials as potential solid oxide fuel cell (SOFC) anodes. The particulate materials were obtained by a one-step synthesis method and characterized by thermal analysis (prior to calcination) and X-ray diffraction (calcined powder). The ceramic processing of samples containing from 30 to 70 wt.% NiO was carried out by factorial design. Besides the NiO content controlled during the chemical synthesis, the impacts of the pore-former content (citric acid, used in proportions of 0, 7.5 and 15 wt.%) and the sintering temperature (1300, 1350 and 1400 °C) were also investigated. The open porosity of NiO-CGO composites and reduced Ni-CGO cermets was modeled as a function of factors (NiO content, citric acid content and sintering temperature) and interaction of factors.

    The structural implications of excess Ni in the TiNiSn half-Heusler compound are examined through a combination of synchrotron x-ray and neutron scattering studies, in conjunction with first principles density functional theory calculations on supercells. Despite the phase diagram suggesting that TiNiSn is a line compound with no solid solution, for small x in TiNi 1+x Sn there is indeed an appearance—from careful analysis of the scattering—of some solubility, with the excess Ni occupying the interstitial tetrahedral site in the half-Heusler structure. The analysis performed here would point to the excess Ni not being statistically distributed, but rather occurring as coherent nanoclusters. First principles calculations of energetics, carried out using supercells, support a scenario of Ni interstitials clustering, rather than a statistical distribution.

    The microstructural change of Ni 40 Zr 60 alloy during mechanical alloying of mixtures of the intermetallic compounds NiZr 2 and Ni 11 Zr 9 has been studied by transmission electron microscopy. A specific ''cauliflower'' phase was formed during early stage of mechanical alloying process. It is suggested that the solid state reaction between intermetallic compounds NiZr 2 and Ni 11 Zr 9 is not the only origin for the formation of the ''cauliflower'' phase. ((orig.))

    Research highlights: → Wear resistant NiMo/Mo 2 Ni 3 Si intermetallic 'in-situ' composites was fabricated successfully with Mo-Ni-Si powder blends as the starting materials. Microstructure of the NiMo/Mo 2 Ni 3 Si composites consists of Mo 2 Ni 3 Si primary dendrites, binary intermetallic phase NiMo and small amount of Ni/NiMo eutectics structure. The NiMo/Mo 2 Ni 3 Si composites exhibited high hardness and outstanding tribological properties under room-temperature dry-sliding wear test conditions which were attributed to the covalent-dominant strong atomic bonds and excellent combination of strength and ductility and toughness. - Abstract: Wear resistant NiMo/Mo 2 Ni 3 Si intermetallic 'in-situ' composites with a microstructure of ternary metal silicide Mo 2 Ni 3 Si primary dendritic, the long strip-like NiMo intermetallic phase, and a small amount of Ni/NiMo eutectics structure were designed and fabricated using molybdenum, nickel and silicon elemental powders. Friction and wear properties of NiMo/Mo 2 Ni 3 Si composites were evaluated under different contact load at room-temperature dry-sliding wear test conditions. Microstructure, worn surface morphologies and subsurface microstructure were characterized by OM, XRD, SEM and EDS. Results indicate that NiMo/Mo 2 Ni 3 Si composites have low fiction coefficient, excellent wear resistance and sluggish wear-load dependence. The dominant wear mechanisms of NiMo/Mo 2 Ni 3 Si composites are soft abrasion and slightly superficial oxidative wear.

    Full Text Available Ni/NiO nanoflower modified reduced graphene oxide (rGO nanocomposite (Ni/NiO-rGO was introduced to screen printed electrode (SPE for the construction of a nonenzymatic electrochemical glucose biosensor. The Ni/NiO-rGO nanocomposite was synthesized by an in situ reduction process. Graphene oxide (GO hybrid Nafion sheets first chemical adsorbed Ni ions and assembled on the SPE. Subsequently, GO and Ni ions were reduced by hydrazine hydrate. The electrochemical properties of such a Ni/NiO-rGO modified SPE were carefully investigated.

    Since the Al-Cu-Ni-Zr system is a basis for the production of bulk amorphous materials by rapid solidification techniques from the liquid state, it is of great scientific interest to determine the partial and the integral thermodynamic functions of liquid and undercooled liquid alloys. Such data, as was pointed out previously, are important in order to understand their extremely good glass-forming ability in multicomponent metallic systems as well as for processing improvements. In order to measure the thermodynamic properties of the Al-Cu-Ni-Zr quaternary, it is necessary to have reliable thermochemical data for its constituent canaries and ternaries first. In a series of articles, the authors have reported in detail the thermodynamic properties of liquid Al-Cu, Al-Ni, Cu-Ni, Cu-Zr, Al-Zr, Al-Cu-Ni, and Al-Cu-Zr alloys. This article deals with the direct calorimetric measurements of the partial and the integral enthalpies of mixing of liquid Ni-Zr and Cu-Ni-Zr alloys and the heat capacity of liquid Ni 26 Zr 74 . In a subsequent article, the authors will present similar data for the liquid ternary Al-Ni-Zr and for the liquid quaternary Al-Cu-Ni-Zr alloys

    The work is in characterisation of mechanisms in the energy range of onset of multifragmentation (excitation energy of composed nucleus around 4 - 5 AMeV). This work focused on an experiment performed at the SARA facility, in Grenoble, using the AMPHORA multi detection array. I have been particularly interested in central collisions in the Ni + Al and Ni + Ni systems. The possibility to detect complete events for Ni + Al, and quasi-complete events for the Ni + Ni case, is the reason of this choice. Furthermore Ni + Ni presents the interest of a symmetrical system, for which the excitation energy per nucleon is maximum. The study of these reactions has been focused on the quasi-complete events (events for which at least 80 % of the total charge has been detected). Heavy ions produced in peripheral collisions are very likely emitted along the beam line or stopped in the plastic detectors, energy thresholds are too high for the quasi-target products detection, consequently by requiring complete or quasi-complete measurement of the total charge, we are able to detect mostly central events. The knowledge of informations like charge, energy or detection angles allows to isolate the source(s) and to reconstruct the size and the excitation energy of the source(s). Comparisons with simulations like sequential emission (GEMINI code), very deep inelastic collision or instantaneous emission (Berliner code) allows to characterise the first stage of the collision (binary collisions or central collisions) and the type of deexcitation of the source(s). Some calculations was also performed with the statistical model code MODGAN. Indeed azimuthal correlations seem to be a good tool in getting more information about involved reaction mechanisms. Comparisons with MODGAN provide information about angular momentum of the source and time delay between emissions of the two particles (separation between sequential or instantaneous process).

    Electrocatalytic activity for the hydrogen evolution reaction on Ni-Co-LaNi{sub 5} composite electrodes prepared by electrochemical codeposition technique was evaluated. The relationship between the current density for hydrogen evolution reaction and the amount of LaNi{sub 5} particles in Ni-Co baths is like the well-known 'volcano plot'. The Surface morphology and microstructure of Ni-Co-LaNi{sub 5} coatings were determined by means of scanning electron microscopy (SEM) and X-ray diffraction (XRD). The kinetic parameters were determined from electrochemical steady-state Tafel polarization and electrochemical impedance spectroscopy technology in 1 M NaOH solution. The values obtained for the apparent energies of activation are 32.48, 46.29 and 57.03 kJ mol{sup -1} for the Ni-Co-LaNi{sub 5}, Ni-Co and Ni electrodes, respectively. The hydrogen evolution reaction on Ni-Co-LaNi{sub 5} proceeds via Volmer-Tafel reaction route with the mixed rate determining characteristics. The composite coating Ni-Co-LaNi{sub 5} is catalytically more active than Ni and Ni-Co electrodes due to the increase in its real surface areas and the decrease in the apparent free energy of activation caused by the electrocatalytic synergistic effect of the Ni-Co alloys and the hydrogen storage intermetallic particles on the electrode surface.

    Numbers of W whiskers were obtained by reducing Ni, Ni-Fe, and Ni-Co doped tungsten oxide in a mixed atmosphere of humid H 2 and N 2 . The phases and morphologies of the reduction products were characterized by XRD and SEM. Intensive TEM and EDS analyses showed that the obtained whiskers were W single crystals which typical have alloyed particles (Ni-W, Fe-Ni, or Co-Ni-W) at the growth tips. The formed W whiskers were presumed to be induced by the alloyed particles. Our experimental results revealed that, during the reduction process of tungsten oxide, the pre-reduced Ni, Fe-Ni, or Co-Ni particles not only served as nucleation aids for the initial growth of W phase from W oxide but also played the roles of catalysts during the reductive decomposition of gaseous WO 2 (OH) 2 .

    Development of exchange bias at the seed and top NiFe layers in the NiFe (t nm)/FeMn(10 nm)/NiFe(5 nm) trilayer structure is investigated as a function of seed layer thickness, in the range of 2-20 nm. The seed NiFe layer shows maximum exchange bias at 4 nm seed layer thickness. The bias shows inverse thickness dependence with increasing thickness. The top NiFe layer on the other hand shows only half the bias of the seed layer which is retained even after the sharp fall in seed layer bias. The much smaller bias for the top NiFe layer is related to the difference in crystalline texture and spin orientations at the top FeMn/NiFe interface, in comparison to the bottom NiFe/FeMn interface which grows on a saturated NiFe layer with (1 1 1) orientation

    Currently, the main bottleneck for the widespread application of Ni-Zn batteries is their poor cycling stability as a result of the irreversibility of the Ni-based cathode and dendrite formation of the Zn anode during the charging-discharging processes. Herein, a highly rechargeable, flexible, fiber-shaped Ni-Zn battery with impressive electrochemical performance is rationally demonstrated by employing Ni-NiO heterostructured nanosheets as the cathode. Benefiting from the improved conductivity and enhanced electroactivity of the Ni-NiO heterojunction nanosheet cathode, the as-fabricated fiber-shaped Ni-NiO//Zn battery displays high capacity and admirable rate capability. More importantly, this Ni-NiO//Zn battery shows unprecedented cyclic durability both in aqueous (96.6% capacity retention after 10 000 cycles) and polymer (almost no capacity attenuation after 10 000 cycles at 22.2 A g -1 ) electrolytes. Moreover, a peak energy density of 6.6 µWh cm -2 , together with a remarkable power density of 20.2 mW cm -2 , is achieved by the flexible quasi-solid-state fiber-shaped Ni-NiO//Zn battery, outperforming most reported fiber-shaped energy-storage devices. Such a novel concept of a fiber-shaped Ni-Zn battery with impressive stability will greatly enrich the flexible energy-storage technologies for future portable/wearable electronic applications. © 2017 WILEY-VCH Verlag GmbH & Co.

    A nonenzymatic glucose electrochemical sensor was constructed based on Au nanoparticles (AuNPs) decorated Ni metal-organic-framework (MOF)/Ni/NiO nanocomposite. Ni-MOF/Ni/NiO nanocomposite was synthesized by one-step calcination of Ni-MOF. Then AuNPs were loaded onto the Ni-based nanocomposites' surface through electrostatic adsorption. Through characterization by transmission electron microscopy (TEM), high resolution TEM (HRTEM) and energy disperse spectroscopy (EDS) mapping, it is found that the AuNPs were well distributed on the surface of Ni-based nanocomposite. Cyclic voltammetric (CV) study showed the electrocatalytic activity of Au-Ni nanocomposite was highly improved after loading AuNPs onto it. Amperometric study demonstrated that the Au-Ni nanocomposites modified glassy carbon electrode (GCE) exhibited a high sensitivity of 2133.5 mA M -1 cm -2 and a wide linear range (0.4-900 μM) toward the oxidation of glucose with a detection limit as low as 0.1 μM. Moreover, the reproducibility, selectivity and stability of the sensor all exhibited outstanding performance. We applied the as-fabricated high performance sensor to measure the glucose levels in human serum and obtained satisfactory results. It is believed that AuNPs decorated Ni MOF/Ni/NiO nanocomposite provides a new platform for developing highly performance electrochemical sensors in practical applications.

    It is now 20 years since super-mirrors were first used as a neutron optical element. Since then the field of multilayer neutron-optics has matured with multilayers finding their way to application in many neutron scattering instruments. However, there is still room for progress in terms of multilayer quality, performance and application. Along with work on multilayers for neutron polarisation Ni/Ti super-mirrors have been optimised. The state-of-the-art Ni/Ti super-mirror performance and the results obtained in two neutron-optics applications of Ni/Ti multilayers are presented. (author).

    Using intrinsic solute segregation in alloys, the compressive stress in a series of Cu(Ni) thin films has been studied. The highest compressive stress was noted in the 5 at.% Ni alloy, with increasing Ni concentration resulting in a subsequent reduction of stress. Atom probe tomography quantified Ni's Gibbsian interfacial excess in the grain boundaries and confirmed that once grain boundary saturation is achieved, the compressive stress was reduced. This letter provides experimental support in elucidating how interfacial segregation of excess adatoms contributes to the post-coalescence compressive stress generation mechanism in thin films. - Graphical abstract: Cu(Ni) film stress relationship with Ni additions. Atom probe characterization confirms solute enrichment in the boundaries, which was linked to stress response.

    The NiCo layers with various Ni/Co atomic ratio have been successfully electroless deposited on PZT layers by varying the bath composition. As the cobalt atomic ratio in the deposited layer increases from 17.2 to 54.8 wt%, the magnetostrictive coefficient decreases. The magnetoelectric effect depends strongly on the magnetostrictive properties of magnetostrictive phase. The magnetoelectric coefficient of NiCo/PZT/NiCo trilayers increases with Ni/Co atomic ratio of the deposited NiCo layers increasing from 45:55 to 83:17. A maximum ME voltage coefficient of α E,31 = 2.8 V ⋅ cm −1 ⋅ Oe −1 is obtained at a frequency of about 88 kHz, which makes these trilayers suitable for applications in actuators, transducers and sensors

    2011-01-01

    Experimental data on phase equilibria have been used for thermodynamic analysis of the iron solubility of the nickel sulfides Ni 7 S 6 and Ni 9 S 8 . For both compounds, a two-sublattice approach within the framework of the compound energy formalism has been applied to perform Gibbs free energy modelling at 0.1 MPa total pressure consistently embedded in recent thermodynamic assessment studies of other iron-nickel-sulfides. The predicted maxima of iron solubility around 3 at% of Ni 7 S 6 and 5.5 at% of Ni 9 S 8 are confirmed by experimental data. The calculations of complex ternary phase relations with Fe-bearing Ni 7 S 6 and Ni 9 S 8 gain further improvement. The first internally consistent description of all thermodynamically stable phases known in the literature for the iron-nickel-sulfur system is completed.

    We show that the differences in stability of 3d-5d NiPt and 3d-4d NiPd alloys arise mainly due to relativistic corrections. The magnetic properties of disordered NiPd and NiPt alloys also differ due to these corrections, which lead to increase in the separation between the s-d bands of 5d elements in these alloys. For the magnetic case we also analyse the results in terms of splitting of majority and minority spin d band centres of the 3d elements. We further examine the effect of relativistic corrections to the pair energies and order-disorder transition temperatures in these alloys. The magnetic moments and Curie temperatures have also been studied along with the short range ordering/segregation effects in NiPt/NiPd alloys

    An experimental study of the graphene, synthesized by propylene cracking on Ni surfaces with different orientation: (100) and (111), using angle-resolved photoemission, has been performed. It has been shown that graphene on Ni(111) had a perfect lateral structure due to consistency of their lattices, whereas graphene/Ni(100) consisted of a lot of domains. For both systems electronic structure was quite similar and demonstrated a strong bonding of graphene to the underlying Ni surface. After Au intercalation the electronic structure of graphene in both systems was shifted to the Fermi level and became linear in the vicinity of the K point of the Brillouin zone. - Highlights: • Graphene on Ni(111) is well-ordered, whereas on Ni(100) – multi-domain. • Graphene on Ni(111) and Ni(100) is strongly bonded with substrate. • Intercalation of Au atoms restores the linearity in dispersion and makes graphene quasi-free on both Ni(100) and Ni(111).
