    1992-03-01

    The Ceramic Technology Project was developed by the USDOE Office of Transportation Systems (OTS) in Conservation and Renewable Energy. This project, part of the OTS's Materials Development Program, was developed to meet the ceramic technology requirements of the OTS's automotive technology programs. Significant accomplishments in fabricating ceramic components for the USDOE and NASA advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. These programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. A five-year project plan was developed with extensive input from private industry. In July 1990 the original plan was updated through the estimated completion of development in 1993. The objective is to develop the industrial technology base required for reliable ceramics for application in advanced automotive heat engines. The project approach includes determining the mechanisms controlling reliability, improving processes for fabricating existing ceramics, developing new materials with increased reliability, and testing these materials in simulated engine environments to confirm reliability. Although this is a generic materials project, the focus is on the structural ceramics for advanced gas turbine and diesel engines, ceramic bearings and attachments, and ceramic coatings for thermal barrier and wear applications in these engines. To facilitate the rapid transfer of this technology to US industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities.

    1994-03-01

    The Ceramic Technology [for Advanced Heat Engines] Project was begun in 1983 to meet the ceramic materials needs of the companion DOE automotive engine program, the Advanced Gas Turbine (AGT) project, and the Heavy Duty Transport (low-heat-rejection, heavy-duty diesel) project. Goal is to develop an industry technology base for reliable and cost effective ceramics for applications in advanced automotive gas turbine and diesel engines. Research areas were identified following extensive input from industry and academia. Majority of research is done by industry (60%); work is also done at colleges and universities, in-house, and at other national laboratories and government agencies. In the beginning, reliability of ceramic components was the key issue. The reliability issues have largely been met and, at the present time, cost is the driving issue, especially in light of the highly cost-sensitive automotive market. Emphasis of the program has now been shifted toward developing cost-effective ceramic components for high-performance engines in the near-term. This bibliography is a compilation of publications done in conjunction with the Ceramic Technology Project since its beginning. Citations were obtained from reports done by participants in the project. We have tried to limit citations to those published and easily located. The end date of 1992 was selected.

    Strongly adherent coatings were deposited on reaction bonded Si{sub 3}N{sub 4} (RBSN), sintered SiC (SSC), and HIP`ed Si{sub 3}N{sub 4} (HSN) and using a newly developed chemical vapor deposition (CVD) process. Performance of the coating was assessed by oxidation, strength and contact stress testing. A new method was developed to experimentally determine the strength and Weibull modulus of thin brittle films on ceramic substrates. A significant portion of the study was devoted to numerical modeling of the coatings in order to understand the contributions of residual stress as different coating materials and thicknesses were combined. Coating designs were further analyzed by simulating the crack growth behavior in multilayer films while accounting for the interface fracture mechanics. This work has shown that the Al{sub 2}0{sub 3+}ZrO{sub 2} composite coating developed in this program can provide resistance to oxidation and contact stress. Commercial application of the composite coating has been successfully demonstrated by useof the Al{sub 2}0{sub 3+}ZrO{sub 2} composite as a protective coating on a Si{sub 3}N{sub 4} cutting tool.

    A short term study has been carried out to evaluate the suitability as cam roller followers of three ceria zirconia toughened aluminas and two yttria stabilized tetragonal zirconias (YTZPs) previously enhanced in programs supported by ORNL. Norton Si{sub 3}N{sub 4} (NBD-100) was also included in this study as a reference material, because it was known from work at Northwestern University that Si{sub 3}N{sub 4} to experienced little or no wear in this application, and NBD-100 is currently a successful commercial bearing material. The tribological studies were subcontracted to the Torrington Company. They found that in cam roller follower simulated tests that there was essentially no wear after 1 hour and 5 hours of testing detectable by weighing and concluded that all of these ceramics are, therefore, candidate materials. Because of the minute amounts of wear it was not possible to identify the wear mechanism or to make any correlations with the other physical properties which were evaluated such as MOR, K{sub IC} hardness, density and grain size. Phase transformation during rolling has been of interest in the tribology of zirconia contain materials. The least stable of the ceria zirconia toughened aluminas resulted in as much as 33% monoclinic phase after testing whereas the yttria stabilized (TTZ) contained very little of this transformed phase. The results of this study show that oxide materials can now be considered as candidates for cam roller followers in heat engines.

    1996-06-01

    Fibrous filters have been used for centuries to protect individuals from dust, disease, smoke, and other gases or particulates. In the 1970s and 1980s ceramic filters were developed for filtration of hot exhaust gases from diesel engines. Tubular, or candle, filters have been made to remove particles from gases in pressurized fluidized-bed combustion and gasification-combined-cycle power plants. Very efficient filtration is necessary in power plants to protect the turbine blades. The limited lifespan of ceramic candle filters has been a major obstacle in their development. The present work is focused on forming fibrous ceramic filters using a papermaking technique. These filters are highly porous and therefore very lightweight. The papermaking process consists of filtering a slurry of ceramic fibers through a steel screen to form paper. Papermaking and the selection of materials will be discussed, as well as preliminary results describing the geometry of papers and relative strengths.

    The goal of the project was to develop the ceramic based materials, technology, and necessary engineering packages to retrofit existing aluminum reduction cells in order to reduce energy consumption required for making primary aluminum. The ceramic materials would be used in a drained cathode configuration which would provide a stable, molten aluminum wetted cathode surface, allowing the reduction of the anode-cathode distance, thereby reducing the energy consumption. This multi-tasked project was divided into three major tasks: (1) Manufacturing and laboratory scale testing/evaluation of the ceramic materials, (2) Pilot scale testing of qualified compositions from the first task, and (3) Designing, retrofitting, and testing the ceramic materials in industrial cells at Kaiser Mead plant in Spokane, Washington. Specific description of these major tasks can be found in Appendix A - Project Scope. Due to the power situation in the northwest, the Mead facility was closed, thus preventing the industrial cell testing.

    1992-06-01

    The tribological properties of a variety of advanced coating materials have been evaluated under conditions which simulate the piston ring -- cylinder liner environment near top ring reversal in a heavy duty diesel engine. Coated ``ring`` samples were tested against a conventional pearlitic grey cast iron liner material using a high temperature reciprocating wear test rig. Tests were run with a fresh CE/SF 15W40lubricant at 200 and 350{degrees}C, with a high-soot, engine-tested oil at 200{degrees}C and with no lubrication at 200{degrees}C. For lowest wear under boundary lubricated conditions, the most promising candidates to emerge from this study were high velocity oxy-fuel (HVOF) Cr{sub 3} C{sub 2} - 20% NiCr and WC - 12% Co cermets, low temperature arc vapor deposited (LTAVD) CrN and plasma sprayed chromium oxides. Also,plasma sprayed Cr{sub 2}O{sub 3} and A1{sub 2}O{sub 3}-ZrO{sub 2} materials were found to give excellent wear resistance in unlubricated tests and at extremely high temperatures (450{degrees}C) with a syntheticoil. All of these materials would offer substantial wear reductions compared to the conventional electroplated hard chromium ring facing and thermally sprayed metallic coatings, especially at high temperatures and with high-soot oils subjected to degradation in diesel environments. The LTAVD CrN coating provided the lowest lubricated wear rates of all the materials evaluated, but may be too thin (4 {mu}m) for use as a top ring facing. Most of the coatings evaluated showed higher wear rates with high-soot, engine-tested oil than with fresh oil, with increases of more than a factor of ten in some cases. Generally, metallic materials were found to be much more sensitive to soot/oil degradation than ceramic and cermet coatings. Thus, decreased ``soot sensitivity`` is a significant driving force for utilizing ceramic or cermet coatings in diesel engine wear applications.

  4. Development of Advanced Ceramic Manufacturing Technology

    Pujari, V.K.

    2001-04-05

    Advanced structural ceramics are enabling materials for new transportation engine systems that have the potential for significantly reducing energy consumption and pollution in automobiles and heavy vehicles. Ceramic component reliability and performance have been demonstrated in previous U.S. DOE initiatives, but high manufacturing cost was recognized as a major barrier to commercialization. Norton Advanced Ceramics (NAC), a division of Saint-Gobain Industrial Ceramics, Inc. (SGIC), was selected to perform a major Advanced Ceramics Manufacturing Technology (ACMT) Program. The overall objectives of NAC's program were to design, develop, and demonstrate advanced manufacturing technology for the production of ceramic exhaust valves for diesel engines. The specific objectives were (1) to reduce the manufacturing cost by an order of magnitude, (2) to develop and demonstrate process capability and reproducibility, and (3) to validate ceramic valve performance, durability, and reliability. The program was divided into four major tasks: Component Design and Specification, Component Manufacturing Technology Development, Inspection and Testing, and Process Demonstration. A high-power diesel engine valve for the DDC Series 149 engine was chosen as the demonstration part for this program. This was determined to be an ideal component type to demonstrate cost-effective process enhancements, the beneficial impact of advanced ceramics on transportation systems, and near-term commercialization potential. The baseline valve material was NAC's NT451 SiAION. It was replaced, later in the program, by an alternate silicon nitride composition (NT551), which utilized a lower cost raw material and a simplified powder-processing approach. The material specifications were defined based on DDC's engine requirements, and the initial and final component design tasks were completed.

    1997-10-01

    This ceramic component design manual was an element of the Advanced Turbine Technology Applications Project (ATTAP). The ATTAP was intended to advance the technological readiness of the ceramic automotive gas turbine engine as a primary power plant. Of the several technologies requiring development before such an engine could become a commercial reality, structural ceramic components represented the greatest technical challenge, and was the prime focus of the program. HVTE-TS, which was created to support the Hybrid Electric Vehicle (HEV) program, continued the efforts begun in ATTAP to develop ceramic components for an automotive gas turbine engine. In HVTE-TS, the program focus was extended to make this technology applicable to the automotive gas turbine engines that form the basis of hybrid automotive propulsion systems consisting of combined batteries, electric drives, and on-board power generators as well as a primary power source. The purpose of the ceramic design manual is to document the process by which ceramic components are designed, analyzed, fabricated, assembled, and tested in a gas turbine engine. Interaction with ceramic component vendors is also emphasized. The main elements of the ceramic design manual are: an overview of design methodology; design process for the AGT-5 ceramic gasifier turbine rotor; and references. Some reference also is made to the design of turbine static structure components to show methods of attaching static hot section ceramic components to supporting metallic structures.

  7. Enabling Technologies for Ceramic Hot Section Components

    Venkat Vedula; Tania Bhatia

    2009-04-30

    Silicon-based ceramics are attractive materials for use in gas turbine engine hot sections due to their high temperature mechanical and physical properties as well as lower density than metals. The advantages of utilizing ceramic hot section components include weight reduction, and improved efficiency as well as enhanced power output and lower emissions as a result of reducing or eliminating cooling. Potential gas turbine ceramic components for industrial, commercial and/or military high temperature turbine applications include combustor liners, vanes, rotors, and shrouds. These components require materials that can withstand high temperatures and pressures for long duration under steam-rich environments. For Navy applications, ceramic hot section components have the potential to increase the operation range. The amount of weight reduced by utilizing a lighter gas turbine can be used to increase fuel storage capacity while a more efficient gas turbine consumes less fuel. Both improvements enable a longer operation range for Navy ships and aircraft. Ceramic hot section components will also be beneficial to the Navy's Growth Joint Strike Fighter (JSF) and VAATE (Versatile Affordable Advanced Turbine Engines) initiatives in terms of reduced weight, cooling air savings, and capability/cost index (CCI). For DOE applications, ceramic hot section components provide an avenue to achieve low emissions while improving efficiency. Combustors made of ceramic material can withstand higher wall temperatures and require less cooling air. Ability of the ceramics to withstand high temperatures enables novel combustor designs that have reduced NO{sub x}, smoke and CO levels. In the turbine section, ceramic vanes and blades do not require sophisticated cooling schemes currently used for metal components. The saved cooling air could be used to further improve efficiency and power output. The objectives of this contract were to develop technologies critical for ceramic hot section

    1990-07-01

    The purpose of the Ceramic Technology for Advanced Heat Engines (CTAHE) Project is the development of an industrial technology base capable of providing reliable and cost-effective high temperature ceramic components for application in advanced heat engines. There is a deliberate emphasis on industrial'' in the purpose statement. The project is intended to support the US ceramic and engine industries by providing the needed ceramic materials technology. The heat engine programs have goals of component development and proof-of-concept.

    Meadow River Enterprises, Inc. (MRE) and the New York State College of Ceramics at Alfred University (NYSCC) received a DOE cooperative agreement award in September 1999 to develop an energy-efficient Solid-State Ceramic Lamp (SSCL). The program spanned a nominal two(2) year period ending in February of 2002. The federal contribution to the program totaled $1.6 million supporting approximately 78% of the program costs. The SSCL is a rugged electroluminescent lamp designed for outdoor applications. MRE has filed a provisional patent for this ''second generation'' technology and currently produces and markets blue-green phosphor SSCL devices. White phosphor SSCL devices are also available in prototype quantities. In addition to reducing energy consumption, the ceramic EL lamp offers several economic and societal advantages including lower lifecycle costs and reduced ''light pollution''. Significant further performance improvements are possible but will require a dramatic change in device physical construction related to the use of micro-powder materials and processes. The subject ''second-generation'' program spans a 27 month period and combines the materials and processing expertise of NYSCC, the manufacturing expertise of Meadow River Enterprises, and the phosphor development expertise of OSRAM Sylvania to develop an improved SSCL system. The development plan also includes important contributions by Marshall University (a part of the West Virginia University system). All primary development objectives have been achieved with the exception of improved phosphor powders. The performance characteristics of the first generation SSCL devices were carefully analyzed in year 1 and a second generation lamp was defined and optimized in year 2. The provisional patent was ''perfected'' through a comprehensive patent application filed in November 2002. Lamp efficiency was improved more than 2:1.

    The Ceramic Technology Project was originally developed by the Department of Energy`s Office of Transportation Systems (OTS) in Energy Efficiency and Renewable Energy. This project, part of the OTS`s Materials Development Program, was developed to meet the ceramic technology requirements of the OTS`s automotive technology programs. Significant accomplishments in fabricating ceramic components for the Department of Energy (DOE), National Aeronautics and Space Administration (NASA), and Department of Defense (DoD) advanced heat engine programs have provided evidence that the operation of ceramic parts in high-temperature engine environments is feasible. However, these programs have also demonstrated that additional research is needed in materials and processing development, design methodology, and data base and life prediction before industry will have a sufficient technology base from which to produce reliable cost-effective ceramic engine components commercially. In response to extensive input from industry, the plan is to extend the engine types which were previously supported (advanced gas turbine and low-heat-rejection diesel engines) to include near-term (5-10 years) applications in conventional automobile and diesel truck engines. To facilitate the rapid transfer of this technology to U.S. industry, the major portion of the work is being done in the ceramic industry, with technological support from government laboratories, other industrial laboratories, and universities. A systematic approach to reducing the cost of components is envisioned. The work elements are as follows: economic cost modeling, ceramic machining, powder synthesis, alternative forming and densification processes, yield improvement, system design studies, standards development, low-expansion ceramics, and testing and data base development.

    The role of ceramic components in fission and fusion reactors is described. Almost all of the functions normally performed by ceramics, except mechanical, are required of nuclear ceramics. The oxides of uranium and plutonium are of predominant importance in nuclear applications, but a number of other ceramics play peripheral roles. The unique service conditions under which nuclear ceramics must operate include intense radiation fields, high temperatures and large temperature gradients, and aggressive chemical environments. Examples of laboratory research designed to broaden understanding of the behavior of uranium dioxide in such conditions are given. The programs described include high temperature vaporization, diffusional processes, and interaction with hydrogen.

    Ceramic membranes have high chemical and thermal stability coupled with mechanical strength and are therefore used in a range of microfiltration, ultrafiltration and nanofiltration applications. This article described a new technology that involves the use of ceramic membranes in the treatment of produced water in thermal heavy oil recovery operations. The efficacy of advanced ceramic nano-membrane technology (CMT) is being examined in bench-scale experiments at the Southern Alberta Institute of Technology (SAIT) in collaboration with the department of chemical and petroleum engineering at the University of Calgary. In one project, next-generation ceramic membrane technology is being used as part of the overall treatment process of produced water. The project is funded through a Canadian Association of Petroleum Producers fund and the Alberta Department of Energy. It is facilitated by the Petroleum Technology Alliance Canada in an effort to find cost-effective treatment solutions for recycling produced water for the conventional oil and gas industry. The key objective is to increase the amount of produced water that can be reused rather than disposed into deep saline aquifers. The research focuses on the pre-treatment of produced water and related salt impacted water by using ceramic membranes for the removal of organic compounds for beneficial reuse downstream. Ceramic membranes consist of a multilayer system and their performance depends on the separation and permeation properties of the membrane as well as its mechanical integrity. It was concluded that the CMT findings will be beneficial to the oil and gas industry in providing practical solutions for the challenging issues associated with de-oiling and produced water treatment. 2 figs.

    1998-12-01

    This final technical report was prepared by Rolls-Royce Allison summarizing the multiyear activities of the Advanced Turbine Technology Applications Project (ATTAP) and the Hybrid Vehicle Turbine Engine Technology Support (HVTE-TS) project. The ATTAP program was initiated in October 1987 and continued through 1993 under sponsorship of the US Department of Energy (DOE), Energy Conservation and Renewable Energy, Office of Transportation Technologies, Propulsion Systems, Advanced Propulsion Division. ATTAP was intended to advance the technological readiness of the automotive ceramic gas turbine engine. The target application was the prime power unit coupled to conventional transmissions and powertrains. During the early 1990s, hybrid electric powered automotive propulsion systems became the focus of development and demonstration efforts by the US auto industry and the Department of energy. Thus in 1994, the original ATTAP technology focus was redirected to meet the needs of advanced gas turbine electric generator sets. As a result, the program was restructured to provide the required hybrid vehicle turbine engine technology support and the project renamed HVTE-TS. The overall objective of the combined ATTAP and HVTE-TS projects was to develop and demonstrate structural ceramic components that have the potential for competitive automotive engine life cycle cost and for operating 3,500 hr in an advanced high temperature turbine engine environment. This report describes materials characterization and ceramic component development, ceramic components, hot gasifier rig testing, test-bed engine testing, combustion development, insulation development, and regenerator system development. 130 figs., 12 tabs.

    Besides a continuous increase of the worldwide use of electricity, the electric energy storage technology market is a growing sector. At the latest since the German energy transition ("Energiewende") was announced, technological solutions for the storage of renewable energy have been intensively studied. Storage technologies in various forms are commercially available. A widespread technology is the electrochemical cell. Here the cost per kWh, e. g. determined by energy density, production process and cycle life, is of main interest. Commonly, an electrochemical cell consists of an anode and a cathode that are separated by an ion permeable or ion conductive membrane - the separator - as one of the main components. Many applications use polymeric separators whose pores are filled with liquid electrolyte, providing high power densities. However, problems arise from different failure mechanisms during cell operation, which can affect the integrity and functionality of these separators. In the case of excessive heating or mechanical damage, the polymeric separators become an incalculable security risk. Furthermore, the growth of metallic dendrites between the electrodes leads to unwanted short circuits. In order to minimize these risks, temperature stable and non-flammable ceramic particles can be added, forming so-called composite separators. Full ceramic separators, in turn, are currently commercially used only for high-temperature operation systems, due to their comparably low ion conductivity at room temperature. However, as security and lifetime demands increase, these materials turn into focus also for future room temperature applications. Hence, growing research effort is being spent on the improvement of the ion conductivity of these ceramic solid electrolyte materials, acting as separator and electrolyte at the same time. Starting with a short overview of available separator technologies and the separator market, this review focuses on ceramic-based separators

    This final report summarizes work accomplished in the program from October 1, 1999 through December 31,2004. While many of the key technical objectives for this program were achieved, after a thorough economic and OTM (Oxygen Transport Membrane) reliability analysis were completed, a decision was made to terminate the project prior to construction of a second pilot reactor. In the program, oxygen with purity greater than 99% was produced in both single tube tests and multi-tube pilot plant tests for over 1000 hours. This demonstrated the technical viability of using ceramic OTM devices for producing oxygen from a high pressure air stream. The oxygen fluxes that were achieved in single tube tests exceeded the original target flux for commercial operation. However, extended testing showed that the mean time to failure of the ceramics was insufficient to enable a commercially viable system. In addition, manufacturing and material strength constraints led to size limitations of the OTM tubes that could be tested. This has a severe impact on the cost of both the ceramic devices, but also the cost of assembling the OTM tubes in a large reactor. As such and combined with significant progress in cost reduction of large cryogenic oxygen separation devices, an economic gain that justifies continued development could not be derived.

    Ceramic integration technologies enable hierarchical design and manufacturing of intricate ceramic and composite parts starting with geometrically simpler units that are subsequently joined to themselves and/or to metals to create components with progressively higher levels of complexity and functionality. However, for the development of robust and reliable integrated systems with optimum performance for high temperature applications, detailed understanding of various thermochemical and thermomechanical factors is critical. Different technical approaches are required for the integration of ceramic to ceramic and ceramic to metal systems. Active metal brazing, in particular, is a simple and cost-effective method to integrate ceramic to metallic components. Active braze alloys usually contain a reactive filler metal (e.g., Ti, Cr, V, Hf etc) that promotes wettability and spreading by inducing chemical reactions with the ceramics and composites. In this presentation, various examples of brazing of silicon nitride to themselves and to metallic systems are presented. Other examples of joining of ceramic composites (C/SiC and SiC/SiC) using ceramic interlayers and the resulting microstructures are also presented. Thermomechanical characterization of joints is presented for both types of systems. In addition, various challenges and opportunities in design, fabrication, and testing of integrated similar (ceramic-ceramic) and dissimilar (ceramic-metal) material systems will be discussed. Potential opportunities and need for the development of innovative design philosophies, approaches, and integrated system testing under simulated application conditions will also be presented.

    Al2O3 ceramic-reinforced photopolymer samples for SLA 3D printing technology were prepared using a silane coupling agent (VTES, vinyltriethoxysilane). Depending on the method used to coat the VTES onto the ceramic surface, the dispersion of ceramic particles in the photopolymer solution was remarkably improved. SEM, TEM and element mapping images showed Al2O3 particles well wrapped with VTES along with well-distributed Al2O3 particles overall on the cross-sectional surfaces of 3D-printed objects. The tensile properties (stress-strain curves) of 3D-printed objects of the ceramic-reinforced photopolymer were investigated as a function of the Al2O3 ceramic content when it ranged from 0 to 20 wt%. The results demonstrate that an Al2O3 ceramic content of 15 wt% resulted in enhanced tensile characteristics.

    ETDP Final Forms was an attempt to demonstrate the fabrication and performance of a ceramic waste form immobilizing the hazardous and radioactive elements of the MSO/SR mineral residues. The ceramic material had been developed previously. The fabrication system was constructed and functioned as designed except for the granulator. Fabrication of our particular ceramic, however, proved unsatisfactory. The ceramic material design was therefore changed toward the end of the project, replacing nepheline with zircon as the sink for silica. Preliminary results were encouraging, but more development is needed. Fabrication of the new ceramic requires major changes in the processing: Calcination and granulation would be replaced by spray drying; and sintering would be at higher temperature. The main goal of the project--demonstrating the fabrication and performance of the waste form--was not achieved. This report summarizes Final Forms' activities. The problem of immobilizing the MSO/SR mineral residues is discussed.

    Near infrared wavelength region between 0.8 and 2 μm is an attractive region for biomedical imaging due to the low loss in biomedical objects in the region. Rare-earth doped ceramic phosphors are known to emit efficient fluorescence in the same wavelength region. The authors have developed micro fluorescence bioimaging system for cellular or tissue imaging and macro one for in vivo imaging. This paper will review the materials synthesis for the near infrared fluorescence probes as well as the system development and demonstrative works. Er-doped or Yb/Er-doped ceramic phosphors were synthesized with required particle size. The phosphors were partly modified with polyethylene glycol to give dispersion and controlled interaction with the biological objects. By using the micro imaging system, nematodes, mouse tissue and M1 cells were observed by detecting 1.5 μm emission from Er doped in the ceramic phosphor. in vivo imaging with the same fluorescence scheme was also performed for the digestive organs of live mouse.

    The goal of this NEUP-IRP project is to develop a fuel concept based on an advanced ceramic coating for Zr-alloy cladding. The coated cladding must exhibit demonstrably improved performance compared to conventional Zr-alloy clad in the following respects: During normal service, the ceramic coating should decrease cladding oxidation and hydrogen pickup (the latter leads to hydriding and embrittlement). During a reactor transient (e.g., a loss of coolant accident), the ceramic coating must minimize or at least significantly delay oxidation of the Zr-alloy cladding, thus reducing the amount of hydrogen generated and the oxygen ingress into the cladding. The specific objectives of this project are as follows: To produce durable ceramic coatings on Zr-alloy clad using two possible routes: (i) MAX phase ceramic coatings or similar nitride or carbide coatings; and (ii) graded interface architecture (multilayer) ceramic coatings, using, for instance, an oxide such as yttria-stabilized zirconia (YSZ) as the outer protective layer. To characterize the structural and physical properties of the coated clad samples produced in 1. above, especially the corrosion properties under simulated normal and transient reactor operating conditions. To perform computational analyses to assess the effects of such coatings on fuel performance and reactor neutronics, and to perform fuel cycle analyses to assess the economic viability of modifying conventional Zr-alloy cladding with ceramic coatings. This project meets a number of the goals outlined in the NEUP-IRP call for proposals, including: Improve the fuel/cladding system through innovative designs (e.g. coatings/liners for zirconium-based cladding) Reduce or eliminate hydrogen generation Increase resistance to bulk steam oxidation Achievement of our goals and objectives, as defined above, will lead to safer light-water reactor (LWR) nuclear fuel assemblies, due to improved cladding properties and built-in accident resistance, as well as

    This paper explains a laboratory process for ceramics crushing. Crushing is performed to obtain powder particles having desired size, shape and grain size distribution for the purpose of improving their formability and sinterability. Crushing devices and methods may vary according to these requirements. A ball mill is suitable for obtaining wide grain size distribution, and a vibration mill and a media stirring mill for obtaining narrow grain size distribution. However, an easily cleanable and inexpensive device suits better in a study stage because what is require for a study is mainly property experiments. Calcinated BaTiO3, for example, is first crushed to several mm or smaller with the dry method by using a mortar and a pestle. Then, it is pulverized to sub-microns with the wet method by using a ball mill, a vibration mill or a media stirring mill. Particle size and its distribution may be measured to evaluate particles before and after the crushing. A sieve can classify particles relatively easily if their size is 50 {mu} m or larger. A particle size distribution measuring device can measure sizes ranging from sub-microns to several hundred {mu}m continuously in a short time. Specific surface area is measured generally by using the nitrogen gas adsorption BET method. 8 refs., 4 figs., 3 tabs.

    2004-01-01

    Affordable fiber-reinforced ceramic matrix composites with multifunctional properties are critically needed for high-temperature aerospace and space transportation applications. These materials have various applications in advanced high-efficiency and high-performance engines, airframe and propulsion components for next-generation launch vehicles, and components for land-based systems. A number of these applications require materials with specific functional characteristics: for example, thick component, hybrid layups for environmental durability and stress management, and self-healing and smart composite matrices. At present, with limited success and very high cost, traditional composite fabrication technologies have been utilized to manufacture some large, complex-shape components of these materials. However, many challenges still remain in developing affordable, robust, and flexible manufacturing technologies for large, complex-shape components with multifunctional properties. The prepreg and melt infiltration (PREMI) technology provides an affordable and robust manufacturing route for low-cost, large-scale production of multifunctional ceramic composite components.

    Sandia National Laboratories Environmental Restoration Technologies Department is developing environmental restoration technologies through funding form the US Department of Energy`s (DOE`s) Office of Science and Technology. Initially, this technology development has been through the Mixed Waste Landfill Integrated Demonstration (MWLID). It is currently being developed through the Contaminant Plume containment and Remediation Focus Area, the Landfill Stabilization Focus Area, and the Characterization, Monitoring, and Sensor Cross-Cutting Program. This Technology Integration Project (TIP) was responsible for transferring MWLID-developed technologies for routine use by environmental restoration groups throughout the DOE complex and commercializing these technologies to the private sector. The MWLID`s technology transfer/commercialization successes were achieved by involving private industry in development, demonstration, and technology transfer/commercialization activities; gathering and disseminating information about MWLID activities and technologies; and promoting stakeholder and regulatory involvement. From FY91 through FY95, 30 Technical Task Plans (TTPs) were funded. From these TTPs, the MWLID can claim 15 technology transfer/commercialization successes. Another seven technology transfer/commercialization successes are expected. With the changeover to the focus areas, the TIP continued the technology transfer/commercialization efforts begun under the MWLID.

    Appropriate technologies able to be easily and economically constructed from readily available materials by local craftspeople have a central role in the alleviation of poverty in the developing world. However, research and development of these technologies are generally apportioned relatively modest support by the developed world's institutions, in part because the operation of many of these appropriate technologies is dependent on relatively well-understood science accessible even to introductory college physics students. This paper describes a project-based assignment used to capitalize on this opportunity to motivate students to learn physics by offering them a chance to make concrete contributions to the optimization of appropriate technologies for sustainable development.

    2014-10-13

    The article presents the interdisciplinary research among organic synthesis, chemistry of polymers and ceramic technology. It presents the synthesis of monoacryloyl esters of fructose and glucose that is 1-O-acryloyl-D-fructose and 3-O-acryloyl-D-glucose, conditions of their polymerization and application in shaping of advanced ceramic powders by the so called gelcasting method. The paper presents the influence of carbohydrate esters on the viscosity of Al2O3 suspensions and microstructure of final ceramic samples. The results showed that synthesized esters of saccharides can play the role of organic monomers able to polymerize in situ and self-cross-linking compounds in gelcasting. The paper presents the proposed structure of polymeric network which is formed from acryloyl ester of glucose during gelcasting process. The paper describes rheological behaviour of slurries composed of synthesized substances and A2O3 powders, wetting angles of alumina substrate by synthesized compounds, differences in glass transition temperatures of polymers and the microstructure of obtained final ceramic samples.

    Effects of processing technology on the properties such as relative density, flexural strength, fracture toughness, hardness, etc. and the microstructure of rare earth yttrium containing Al2O3/(W, Ti)C ceramic composite were experimentally investigated. It suggests that different processing parameters can undoubtedly result in different microstructures and different mechanical properties of the material. Under the experimental conditions, the suitable hot pressing temperature is 1720 ~ 1780 ℃, the time duration is 10 ~ 30 min and the hot pressing pressure is 30 ~ 35 MPa. The corresponding relative density can even be higher than 98 %. With SEM and TEM observation, each phases in the ceramic material is found to be in fine grains and distribute homogeneously. Typical fracture feature of the material is the mixture of both intergranular and introgranular fracture. Additionally, the existence of rare earth yttrium containing nanometer or sub-micron meter sized ceramic grains, dislocations and spontaneous microcracks can also contribute to the further improvement of the mechanical properties of the ceramic composite.

    2008-01-01

    The Cryogenic Fluid Management (CFM) Project's primary objective is to develop storage, transfer, and handling technologies for cryogens that will support the enabling of high performance cryogenic propulsion systems, lunar surface systems and economical ground operations. Such technologies can significantly reduce propellant launch mass and required on-orbit margins, reduce or even eliminate propellant tank fluid boil-off losses for long term missions, and simplify vehicle operations. This paper will present the status of the specific technologies that the CFM Project is developing. The two main areas of concentration are analysis models development and CFM hardware development. The project develops analysis tools and models based on thermodynamics, hydrodynamics, and existing flight/test data. These tools assist in the development of pressure/thermal control devices (such as the Thermodynamic Vent System (TVS), and Multi-layer insulation); with the ultimate goal being to develop a mature set of tools and models that can characterize the performance of the pressure/thermal control devices incorporated in the design of an entire CFM system with minimal cryogen loss. The project does hardware development and testing to verify our understanding of the physical principles involved, and to validate the performance of CFM components, subsystems and systems. This database provides information to anchor our analytical models. This paper describes some of the current activities of the NASA's Cryogenic Fluid Management Project.

    For centuries, biology has provided fertile ground for hypothesis, discovery, and inspiration. Time-tested methods used in nature are being used as a basis for several research studies conducted at the NASA Langley Research Center as a part of Morphing Project, which develops and assesses breakthrough vehicle technologies. These studies range from low drag airfoil design guided by marine and avian morphologies to soaring techniques inspired by birds and the study of small flexible wing vehicles. Biology often suggests unconventional yet effective approaches such as non-planar wings, dynamic soaring, exploiting aeroelastic effects, collaborative control, flapping, and fibrous active materials. These approaches and other novel technologies for future flight vehicles are being studied in NASA's Morphing Project. This paper will discuss recent findings in the aeronautics-based, biologically-inspired research in the project.

    2009-07-01

    In this paper a novel micromachined contactless conductivity CE device produced in low temperature co-fired ceramics (LTCC) is introduced. The application of LTCC multilayer technology provides a promising method for the contactless detection of conductive compounds because of its increased dielectric constant compared with glass or plastics. The capacitive coupling of the excitation signal into the microchannel across the LTCC substrate is improved, resulting in better detection sensitivity. Two silver electrodes located externally at opposite sides at the end of the separation channel act as detector. Impedance variations in the channel are measured without galvanic contact between electrodes and fluid. Inorganic ions are separated in less than 1 min with this novel ceramic device. The limit of detection is 10 microM for potassium.

    2011-07-06

    We present results of X-ray fluorescence (XRF) microprobe analyses of ancient ceramic cross-sections aiming at deciphering the different firing protocols used for their production. Micro-focused XRF elemental mapping, Fe chemical mapping and Fe K-edge X-ray absorption near edge structure spectroscopy were performed on pre-sigillata ceramics from southern Gaul, and terra Sigillata vessels from Italy and southern Gaul. Pieces from the different workshops and regions showed significant difference in the starting clay material, clay conditioning and kiln firing condition. By contrast, sherds from the same workshop exhibited more subtle differences and possible misfirings. Understanding the precise firing conditions and protocols would allow recreation of kilns for various productions. Furthermore, evolution and modification of kiln design would shed some light on how ancient potters devised solutions to diverse technological problems they encountered.

    The prime driving force for using microsystem and micromachine technologies in transport vehicles, such as spacecraft, aircraft, and automobiles, is to reduce the weight, power consumption, and volume of components and systems to lower costs and increase affordability and reliability. However, a number of specific issues need to be addressed with respect to using microsystems and micromachines in aerospace applications--such as the lack of understanding of material characteristics; methods for producing and testing the materials in small batches; the limited proven durability and lifetime of current microcomponents, packaging, and interconnections; a cultural change with respect to system designs; and the use of embedded software, which will require new product assurance guidelines. In regards to material characteristics, there are significant adhesion, friction, and wear issues in using microdevices. Because these issues are directly related to surface phenomena, they cannot be scaled down linearly and they become increasingly important as the devices become smaller. When microsystems have contacting surfaces in relative motion, the adhesion and friction affect performance, energy consumption, wear damage, maintenance, lifetime and catastrophic failure, and reliability. Ceramics, for the most part, do not have inherently good friction and wear properties. For example, coefficients of friction in excess of 0.7 have been reported for ceramics and ceramic composite materials. Under Alternate Fuels Foundation Technologies funding, two-phase oxide ceramics developed for superior high-temperature wear resistance in NASA's High Operating Temperature Propulsion Components (HOTPC) project and new two-layered carbon nanotube (CNT) coatings (CNT topcoat/iron bondcoat/quartz substrate) developed in NASA's Revolutionary Aeropropulsion Concepts (RAC) project have been chosen as a materials couple for aerospace applications, including micromachines, in the nanotechnology

    Alternative technological approach is proposed enabling utilization of raw materials from an oil refinery, such as waste guard layers from reactors. Reagent grade and purified MgO, Cr{sub 2}O{sub 3}, Fe{sub 2}O{sub 3}, and nitric acid (HNO{sub 3}), were used as additional precursors. The homogeneous mixtures obtained were formed into pellets and sintered at different temperatures. The main phase was proved by X-ray phase analysis (XRD) and compared to ICPDS database. The main phase in the ceramics synthesized was solid solution of spinel MgAl{sub 2}O{sub 4} and magnesiochromite. These minerals are classified as chromspinelide MgCr{sub 1}.2Al{sub 0}.4Fe{sub 0}.4O{sub 4} and alumochromite MgCr{sub 1}.6Al{sub 0}.4O{sub 4}. Additional SEM observations, combined with EDX analysis were performed, evincing agglomeration at lower temperatures, followed by agglomerate crumbling, at elevated calcination temperature. The complete transformation of initial precursors into the final ceramic compounds was found to occur at 800 degree centigrade 1 h. The ceramic samples synthesized had high density of 1.72-1.93 g/cm{sup 3} and large absorption area - 32.93% which is probably due to the high porosity of the sample. (Author)

    2012-09-30

    A technology maturation plan (TMP) was developed for immobilization of high-level waste (HLW) raffinate in a glass ceramics waste form using a cold-crucible induction melter (CCIM). The TMP was prepared by the following process: 1) define the reference process and boundaries of the technology being matured, 2) evaluate the technology elements and identify the critical technology elements (CTE), 3) identify the technology readiness level (TRL) of each of the CTE’s using the DOE G 413.3-4, 4) describe the development and demonstration activities required to advance the TRLs to 4 and 6 in order, and 5) prepare a preliminary plan to conduct the development and demonstration. Results of the technology readiness assessment identified five CTE’s and found relatively low TRL’s for each of them: • Mixing, sampling, and analysis of waste slurry and melter feed: TRL-1 • Feeding, melting, and pouring: TRL-1 • Glass ceramic formulation: TRL-1 • Canister cooling and crystallization: TRL-1 • Canister decontamination: TRL-4 Although the TRL’s are low for most of these CTE’s (TRL-1), the effort required to advance them to higher values. The activities required to advance the TRL’s are listed below: • Complete this TMP • Perform a preliminary engineering study • Characterize, estimate, and simulate waste to be treated • Laboratory scale glass ceramic testing • Melter and off-gas testing with simulants • Test the mixing, sampling, and analyses • Canister testing • Decontamination system testing • Issue a requirements document • Issue a risk management document • Complete preliminary design • Integrated pilot testing • Issue a waste compliance plan A preliminary schedule and budget were developed to complete these activities as summarized in the following table (assuming 2012 dollars).

    A multi-phase ceramic waste form is being developed at the Savannah River National Laboratory (SRNL) for treatment of secondary waste streams generated by reprocessing commercial spent nuclear. The envisioned waste stream contains a mixture of transition, alkali, alkaline earth, and lanthanide metals. Ceramic waste forms are tailored (engineered) to incorporate waste components as part of their crystal structure based on knowledge from naturally found minerals containing radioactive and non-radioactive species similar to the radionuclides of concern in wastes from fuel reprocessing. The ability to tailor ceramics to mimic naturally occurring crystals substantiates the long term stability of such crystals (ceramics) over geologic timescales of interest for nuclear waste immobilization [1]. A durable multi-phase ceramic waste form tailored to incorporate all the waste components has the potential to broaden the available disposal options and thus minimize the storage and disposal costs associated with aqueous reprocessing. This report summarizes results from three years of work on the IAEA Coordinated Research Project on “Processing technologies for high level waste, formulation of matrices and characterization of waste forms” (T21027), and specific task “Melt Processed Crystalline Ceramic Waste Forms for Advanced Nuclear Fuel Cycles” (17208).

    The objective of this work was to investigate, develop, and validate the next generation of small hydroturbine generator designs that maximize the energy transfer from flowing water to electrical power generation. What resulted from this effort was the design of a new technology hydroturbine that Near Space Systems (NSS) has named the Star*Stream© Hydroturbine. Using a design that eliminates nearly all of the shortfalls of conventional hydroturbines, the Star*Stream© Hydroturbine employs a new mechanical-to-electrical energy transfer hydro design that operates without lubrication of any kind, and does not introduce foreign chemicals or particulate matter from oil or drive shaft seal degradation into the hydro ecology. In its unique configuration, the Star*Stream© Hydroturbine is nearly environmentally inert, without the negative aspects caused by interrupting the ecological continuity, i.e., disruptions to sedimentation, water quality, habitat changes, human displacement, fish migration, etc., - while it ensures dramatically reduced timeframes to project completion. While a remarkable reduction in LCOE resulting from application of the Star*Stream© Hydroturbine technology has been the core achievement of the this effort, there have been numerous technological breakthroughs from the development effort.

    2000-04-01

    The UCSD led I-5/Gilman Advanced Technology Bridge Project will design and construct a fully functional traffic bridge of advanced composite materials across Interstate 5 in La Jolla, California. Its objective is to demonstrate the use of advanced composite technologies developed by the aerospace industry in commercial applications to increase the life expectancy of new structures and for the rehabilitation of aging infrastructure components. The structure will be a 450 ft long, 60 ft wide cable-stayed bridge supported by a 150 ft A-frame pylon with two vehicular lanes, two bicycle lanes, pedestrian walkways and utility tunnels. The longitudinal girders and pylon will be carbon fiber shells filled with concrete. The transverse deck system will consist of hollow glass/carbon hybrid tubes and a polypropylene fiber reinforced concrete deck with an arch action. Selected cables will be composite. The bridge's structural behavior will be monitored to determine how advanced composite materials perform in civil infrastructure applications. The bridge will be instrumented to obtain performance and structural health data in real time and, where possible, in a remote fashion. The sensors applied to the bridge will include electrical resistance strain gages, fiberoptic Bragg gratings and accelerometers.

    2014-01-01

    In this paper, a novel capacitance pressure sensor based on Low-Temperature Co-Fired Ceramic (LTCC) technology is proposed for pressure measurement. This approach differs from the traditional fabrication process for a LTCC pressure sensor because a 4J33 iron-nickel-cobalt alloy is applied to avoid the collapse of the cavity and to improve the performance of the sensor. Unlike the traditional LTCC sensor, the sensitive membrane of the proposed sensor is very flat, and the deformation of the se...

    2006-06-01

    In an attempt to prevent diarrhoea in a rural community in central Bolivia, an international non-governmental organization implemented a pilot project to improve drinking water quality using gravity-fed, household-based, ceramic water filters. We assessed the performance of the filters by conducting a five-month randomized controlled trial among all 60 households in the pilot community. Water filters eliminated thermotolerant (faecal) coliforms from almost all intervention households and significantly reduced turbidity, thereby improving water aesthetics. Most importantly, the filters were associated with a 45.3% reduction in prevalence of diarrhoea among the study population (p = 0.02). After adjustment for household clustering and repeated episodes in individuals and controlling for age and baseline diarrhoea, prevalence of diarrhoea among the intervention group was 51% lower than controls, though the protective effect was only borderline significant (OR 0.49, 95% CI: 0.24, 1.01; p = 0.05). A follow-up survey conducted approximately 9 months after deployment of the filters found 67% being used regularly, 13% being used intermittently, and 21% not in use. Water samples from all regularly used filters were free of thermotolerant coliforms.

    The New York State Electric & Gas Corporation (NYSEG) demonstrated a combination of technologies at its Milliken Station in Lansing, New York, designed to: (1) achieve high sulfur dioxide (SO2) capture efficiency, (2) bring nitrogen oxide (NOx) emissions into compliance with Clean Air Act Amendments of 1990 (CAAA), (3) maintain high station efficiency, and (4) eliminate waste water discharge. This project is part of the U.S. Department of Energy's (DOE) Clean Coal Technology Demonstration Program (CCTDP) established to address energy and environmental concerns related to coal use. DOE sought cost-shared partnerships with industry through five nationally competed solicitations to accelerate commercialization of the most promising advance coal-based power generation and pollution control technologies. The CCTDP, valued at over five billion dollars, has significantly leveraged federal funding by forging effective partnerships founded on sound principles. For every federal dollar invested, CCTDP participants have invested two dollars. These participants include utilities, technology developers, state governments, and research organizations. The project presented here was one of nine selected in January 1991 from 33 proposals submitted in response to the program's fourth solicitation.

  18. Ceramics and ceramic matrix composites - Aerospace potential and status

    Science.gov (United States)

    Levine, Stanley R.

    1992-01-01

    Thermostructural ceramics and ceramic-matrix composites are attractive in numerous aerospace applications; the noncatastrophic fracture behavior and flaw-insensitivity of continuous fiber-reinforced CMCs renders them especially desirable. The present development status evaluation notes that, for most highly-loaded high-temperature applications, the requisite fiber-technology base is at present insufficient. In addition to materials processing techniques, the life prediction and NDE methods are immature and require a projection of 15-20 years for the maturity of CMC turbine rotors. More lightly loaded, moderate temperature aircraft engine applications are approaching maturity.

    Digital impressions were introduced to overcome some of the obstacles due to traditional impression materials and techniques. The aim of this in vitro study is to compare the accuracy of all ceramic crowns obtained with digital impression and CAD-CAM technology with the accuracy of those obtained with conventional impression techniques. Two groups of 10 crowns each have been considered. The digital data obtained from Group 1 have been processed and the all-ceramic crowns were milled with a CAD/CAM technology (CEREC MCX, Sirona). The all ceramic crowns in Group 2 were obtained with the classical technique of pressing (emax, Ivoclar, Vivadent). The evaluation of the marginal adaptation was performed with Time Domain Optical Coherence Tomography (TD OCT), working at a wavelength of 1300 nm. Tri-dimensional (3D) reconstructions of the selected areas were obtained. Based on the findings in this study, one may conclude that the marginal accuracy of all ceramic crowns fabricated with digital impression and the CAD/CAM technique is superior to the conventional impression technique.

    Technology of water-stabilized plasma torch was recently substantially updated through introduction of a so-called hybrid concept that combines benefits of water stabilization and gas stabilization principles. The high-enthalpy plasma provided by the WSP-H ("hybrid") torch may be used for thermal spraying of powders as well as liquid feedstocks with high feed rates. In this study, results from three selected experiments with suspension plasma spraying with WSP-H technology are presented. Possibility of deposition of coatings with controlled microstructures was demonstrated for three different ceramics (YSZ—yttria-stabilized zirconia, YAG—yttrium aluminum garnet and Al2O3) introduced into ethanol-based suspensions. Shadowgraphy was used for optimization of suspension injection and visualization of the liquid fragmentation in the plasma jet. Coatings were deposited onto substrates attached to the rotating carousel with integrated temperature monitoring and air cooling, which provided an excellent reproducibility of the deposition process. Deposition of columnar-like YSZ and dense YAG and Al2O3 coatings was successfully achieved. Deposition efficiency reached more than 50%, as evaluated according to EN ISO 17 836 standard.

    The goals of the NASA Environmentally Responsible Aviation (ERA) Project are to reduce the NO(x) emissions, fuel burn, and noise from turbine engines. In order to help meet these goals, commercially-produced ceramic matrix composite (CMC) components and environmental barrier coatings (EBCs) are being evaluated as parts and panels. The components include a CMC combustor liner, a CMC high pressure turbine vane, and a CMC exhaust nozzle as well as advanced EBCs that are tailored to the operating conditions of the CMC combustor and vane. The CMC combustor (w/EBC) could provide 2700 F temperature capability with less component cooling requirements to allow for more efficient combustion and reductions in NOx emissions. The CMC vane (w/EBC) will also have temperature capability up to 2700 F and allow for reduced fuel burn. The CMC mixer nozzle will offer reduced weight and improved mixing efficiency to provide reduced fuel burn. The main objectives are to evaluate the manufacturability of the complex-shaped components and to evaluate their performance under simulated engine operating conditions. Progress in CMC component fabrication, evaluation, and testing is presented in which the goal is to advance from the proof of concept validation (TRL 3) to a system/subsystem or prototype demonstration in a relevant environment (TRL 6).

    Microstructure of vitreous ceramic samples manufactured from kaolinitic-clay and feldspars raw materials from Cameroon was investigated in the range 1150-1250 deg. C by X-ray diffraction and scanning electron microscopy and by measuring some technological properties. Moreover, the simultaneous influence of feldspars content, heating temperature and soaking time on water absorption and firing shrinkage was evaluated by adopting the response surface methodology (Doehlert matrix), using the New Efficient Methodology for Research using Optimal Design (NEMROD) software. The results show that a spinel phase, mullite, glassy phase and some amount of hematite were formed. However, the spinel phase and potassic feldspar, as compared to the sodic one, disappeared at moderate firing temperature and soaking time. Apparently, mullite developed from spinel phase, which is formed from the demixion of metakaolin. On the other hand, it is found that the effects of fluxing content and firing temperature on the measured properties were almost similar and more influent than soaking time. Antagonistic and synergetic interactions existed between the considered parameters, and their importance differed for the considered properties. By using this mathematical tool, suitable operating conditions for manufacturing vitreous bodies were determined.

    1993-11-01

    The BMDO-New Mexico Technology Transfer Demonstration Project(BMDO-NM) was a collaborative effort among the national laboratories to identify and evaluate the commercial potential of selected SDI-funded technologies. The project was funded by BMDO (formerly known as the Strategic Defense Initiative Office or SDIO), the Technology Enterprise Division (NM-TED) of the NM Economic Development Division, and the three National Laboratories. The project was managed and supervised by SAGE Management Partners of Albuquerque, and project funding was administered through the University of New Mexico. The BMDO-NM Demonstration Project focused on the development of a process to assist technology developers in the evaluation of selected BMDO technology programs so that commercialization decisions can be made in an accelerated manner. The project brought together BMDO, the NM-TED, the University of New Mexico, and three New Mexico Federal laboratories -- Los Alamos (DOE), Phillips (DOD) and Sandia (DOE). Each national laboratory actively participated throughout the project through its technology transfer offices. New Mexico was selected as the site for the Demonstration Program because of its three national and federal research laboratories engaged in BMDO programs, and the existing relationship among state govemment, the labs, universities and local economic development and business assistance organizations. Subsequent Commercialization and Implementation phases for the selected technologies from LANL and SNL were completed by SAGE and the Project Team. Funding for those phases was provided by the individual labs as well as BMDO and NM-TED in kind services. NM-TED played a proactive role in this New Mexico partnership. Its mandate is to promote technology-based economic development, with a commitment to facilitate the use of technology by industry and business statewide. TED assumed the role of program manager and executing agent for BMDO in this demonstration project.

    The generally acknowledged sources of renewable energy are wind, geothermal, biomass, solar, hydropower, and hydrogen. Renewable energy technologies are crucial to the production and utilization of energy from these regenerative and virtually inexhaustible sources. Furthermore, renewable energy technologies provide benefits beyond the establishment of sustainable energy resources. For example, these technologies produce negligible amounts of greenhouse gases and other pollutants in providing energy, and they exploit domestically available energy sources, thereby reducing our dependence on both the importation of fossil fuels and the use of nuclear fuels. The market price of renewable energy technologies does not reflect the economic value of these added benefits.

This approach differs from the traditional fabrication process for a LTCC pressure sensor because a 4J33 iron-nickel-cobalt alloy is applied to avoid the collapse of the cavity and to improve the performance of the sensor. Unlike the traditional LTCC sensor, the sensitive membrane of the proposed sensor is very flat, and the deformation of the sensitivity membrane is smaller. The proposed sensor also demonstrates a greater responsivity, which reaches as high as 13 kHz/kPa in range of 0–100 kPa. During experiments, the newly fabricated sensor, which is only about 6.5 cm2, demonstrated very good performance: the repeatability error, hysteresis error, and nonlinearity of the sensor are about 4.25%, 2.13%, and 1.77%, respectively.

  12. Success in large high-technology projects: What really works?

    Science.gov (United States)

    Crosby, P.

    2014-08-01

    Despite a plethora of tools, technologies and management systems, successful execution of big science and engineering projects remains problematic. The sheer scale of globally funded projects such as the Large Hadron Collider and the Square Kilometre Array telescope means that lack of project success can impact both on national budgets, and collaborative reputations. In this paper, I explore data from contemporary literature alongside field research from several current high-technology projects in Europe and Australia, and reveal common `pressure points' that are shown to be key influencers of project control and success. I discuss the how mega-science projects sit between being merely complicated, and chaotic, and explain the importance of understanding multiple dimensions of project complexity. Project manager/leader traits are briefly discussed, including capability to govern and control such enterprises. Project structures are examined, including the challenge of collaborations. I show that early attention to building project resilience, curbing optimism, and risk alertness can help prepare large high-tech projects against threats, and why project managers need to understand aspects of `the silent power of time'. Mission assurance is advanced as a critical success function, alongside the deployment of task forces and new combinations of contingency plans. I argue for increased project control through industrial-style project reviews, and show how post-project reviews are an under-used, yet invaluable avenue of personal and organisational improvement. Lastly, I discuss the avoidance of project amnesia through effective capture of project knowledge, and transfer of lessons-learned to subsequent programs and projects.

    1989-03-01

    Intensive and continuous tactical training during the last 35 years at the Hohenfels Training Area in West Germany has caused the loss of vegetative ground cover and has accelerated soil erosion rates, resulting in extensive environmental damage, safety hazards, and unrealistic training habitats. The objectives of this project are to develop and evaluate revegetation procedures for establishing adequate vegetative cover to control erosion at minimal costs and disruption to training activities. This project involved the development and installation of 12 revegetation procedures that combined four seedbed preparation methods and seeding options with three site-closure periods. In March 1987, the four seedbed preparation/seeding options and closure periods were selected, a study site design and location chosen, and specifications for the revegetation procedures developed. A German rehabilitation contractor attempted the specified seedbed preparation and seeding on the 13.5-ha site in June, but abnormally high rainfall, usually wet site conditions, and lack of adequate equipment prevented the contractor from completing six of the 12 planned procedures. Planning and execution of the project has nonetheless provided valuable information on the importance and use of soil analytical results, seed availability and cost data, contractor equipment requirements, and time required for planning future revegetation efforts. Continued monitoring of vegetative ground cover at the site for the next two years, combined with cost information, will provide necessary data to determine which of the six revegetation procedures is the most effective. These data will be used in planning future rehabilitation efforts on tactical training areas.

    The main objectives of this project are to establish the international collaboration basis of optical technologies between Korea and China. The combination of the Chinese advanced fundamental technologies with the Korean industrialization and commercialization infrastructures is realized, by ways of exchanging scientists and informations, holding joint seminars, cooperative utilization of research resources. On the ground of this establishment, the optical technologies of Korea are supposed to be leveled up to those of the world-most advanced. At the same time, for the improvement of mutual benefit and financial profit of both countries, providing technical advice and suggestions to the optical industries in the two countries is an another goal of this project. The state-of-the-arts of the Chinese technologies such as aerospace engineering, military defence technology, medical technology, laser fusion research, and so on, are known to be far above those of Korean and up to one of the most advanced in the world. Thus it is thought to be necessary that the acquisition of these technologies, implementation of joint research projects for technology development as well as the balanced opportunities for commercial product/sales and cooperation should be actively pursued in order to enhance the levels of Korean technologies in these fields.

    Advancements in bio-ceramic technology has revolutionised endodontic material science by enhancing the treatment outcome for patients. This class of dental materials conciliates excellent biocompatibility with high osseoconductivity that render them ideal for endodontic care. Few recently introduced bio-ceramic materials have shown considerable clinical success over their early generations in terms of good handling characteristics. Calcium enriched mixture (CEM) cement, Endosequence sealer, and root repair materials, Biodentine and BioAggregate are the new classes of bio-ceramic materials. The aim of this literature review is to present investigations regarding properties and applications of CEM cement in endodontics. A review of the existing literature was performed by using electronic and hand searching methods for CEM cement from January 2006 to December 2013. CEM cement has a different chemical composition from that of mineral trioxide aggregate (MTA) but has similar clinical applications. It combines the biocompatibility of MTA with more efficient characteristics, such as significantly shorter setting time, good handling characteristics, no staining of tooth and effective seal against bacterial leakage.

    2012-05-01

    Full Text Available This study evaluates the concept of success in project management that is applicable to the IT universe, from the classical theory associated with the techniques of project management. Therefore, it applies the theoretical analysis associated to the context of information technology in enterprises as well as the classic literature of traditional project management, focusing on its application in business information technology. From the literature developed in the first part of the study, four propositions were prepared for study which formed the basis for the development of the field research with three large companies that develop projects of Information Technology. The methodology used in the study predicted the development of the multiple case study. Empirical evidence suggests that the concept of success found in the classical literature in project management adjusts to the environment management of IT projects. Showed that it is possible to create the model of standard IT projects in order to replicate it in future derivatives projects, which depends on the learning acquired at the end of a long and continuous process and sponsorship of senior management, which ultimately results in its merger into the company culture.

    Roode, M. van [Solar Turbines Inc., San Diego, CA (United States)

    1995-10-01

    The performance of current industrial gas turbines is limited by the temperature and strength capabilities of the metallic structural materials in the engine hot section. Because of their superior high-temperature strength and durability, ceramics can be used as structural materials for hot section components (blades, nozzles, combustor liners) in innovative designs at increased turbine firing temperatures. The benefits include the ability to increase the turbine inlet temperature (TIT) to about 1200{degrees}C ({approx}2200{degrees}F) or more with uncooled ceramics. It has been projected that fully optimized stationary gas turbines would have a {approx}20 percent gain in thermal efficiency and {approx}40 percent gain in output power in simple cycle compared to all metal-engines with air-cooled components. Annual fuel savings in cogeneration in the U.S. would be on the order of 0.2 Quad by 2010. Emissions reductions to under 10 ppmv NO{sub x} are also forecast. This paper describes the progress on a three-phase, 6-year program sponsored by the U.S. Department of Energy, Office of Industrial Technologies, to achieve significant performance improvements and emissions reductions in stationary gas turbines by replacing metallic hot section components with ceramic parts. Progress is being reported for the period September 1, 1994, through September 30, 1995.

    Ali Mehrabian

    2008-06-01

    Full Text Available Present technology and the accessibility of internet have made distance learning easier, more efficient, and more convenient for students. This technology allows instructors and students to communicate asynchronously, at times and locations of their own choosing, by exchanging printed or electronic information. The use of project-based approach is being recognized in the literature as a potential component of courses in the faculties of engineering, science, and technology. Instructors may have to restructure their course differently to accommodate and facilitate the effectiveness of distance learning. A project-based engineering course, traditionally taught in a classroom settings using live mode at the College of Engineering and Computer Sciences at the University of Central Florida (UCF has been transformed to a distance course taught using distance modes. In this case, pedagogical transitions and adjustments are required, in particular for obtaining an optimal balance between the course material and the project work. Project collaboration in groups requires communication, which is possible with extensive utilization of new information and communication technology, such as virtual meetings. This paper discusses the course transition from live to distance modes and touches on some issues as they relate to the effectiveness of this methodology and the lessons learned from its application within different context. More specifically, this discussion includes the benefit of implementing project-based work in the domain of the distance learning courses.

    2005-07-01

    Pipelines are regarded by many as passive structures with the technology involved in their construction and operation being viewed as relatively simple and stable. If such is the case how can there be much room for cost improvement? In reality, there have been many technological and regulatory innovations required within the pipeline industry to meet the challenges posed by ever increasing consumer demand for hydrocarbons, the effects of aging infrastructure and a need to control operating and maintenance expenditures. The importance of technology management, as a subset of overall project management, is a key element of life cycle cost control. Assurance of public safety and the integrity of the system are other key elements in ensuring a successful pipeline project. The essentials of best practise project management from an owner/ operator's perspective are set out in the paper. Particular attention is paid to the appropriate introduction of new technology, strategic procurement practice and material selection, indicating that capital cost savings of up to 15% are achievable without harming life cycle cost. The value of partnering leading to technical innovation, cost savings and improved profitability for all the participants is described. Partnering also helps avoid duplicated effort through the use of common tools for design, planning schedule tracking and reporting. Investing in appropriate technology development has been a major source of cost reduction in recent years and the impact of a number of these recently introduced technologies in the areas of materials, construction processes and operation and maintenance are discussed in the paper.

    Space-related educational activities is a very inspiring and attractive way to involve students into science courses, present them the variety of STEM careers that they can follow, while giving them at the same time the opportunity to develop various practical and communication skills necessary for their future professional development. As part of a large scale extracurricular course in Space Science, Space Technology and Robotics that has been introduced in our school, our students, divided in smaller groups of 3-4 students in each, try to understand the challenges that current and future space exploration is facing. Following a mixture of an inquiry-based learning methodology and hands-on practical activities related with constructions and experiments, students get a glimpse of the pre-mentioned fields. Our main goal is to gain practical knowledge and inspiration from the exciting field of Space, to attain an adequate level of team spirit and effective cooperation, while developing technical and research data-mining skills. We use the following two approaches: 1. Constructive (Technical) approach Designing and constructing various customized robotic machines, that will simulate the future space exploration vehicles and satellites needed to study the atmosphere, surface and subsurface of planets, moons or other planetary bodies of our solar system that have shown some promising indications for the existence of life, taking seriously into account their special characteristics and known existing conditions (like Mars, Titan, Europa & Enceladus). The STEM tools we use are the following: - LEGO Mindstorms: to construct rovers for surface exploration. - Hydrobots: an MIT's SeaPerch program for the construction of submarine semi-autonomous robots. - CanSats: Arduino-based microsatellites able to receive, record & transmit data. - Space balloons: appropriate for high altitude atmospheric measurements & photography. 2.

    The World Health Organization (WHO) recognizes point-of-use water treatment (PoUWT) technologies as effective means to improve water quality. This paper investigates long-term performance and social acceptance of a novel PoUWT technology, a silver-infused ceramic tablet, in Limpopo Province, South Africa. When placed in a water storage container, the silver-embedded ceramic tablet releases silver ions into water, thereby disinfecting microbial pathogens and leaving the water safe for human consumption. As a result of its simplicity and efficiency, the silver-embedded ceramic tablet can serve as a stand-alone PoUWT method and as a secondary PoUWT to improve exisitng PoUWT methods, such as ceramic water filters. In this paper, three PoUWT interventions were conducted to evaluate the silver-embedded ceramic tablet: (1) the silver-embedded ceramic tablet as a stand-alone PoUWT method, (2) ceramic water filters stand-alone, and (3) a filter-tablet combination. The filter-tablet combination evaluates the silver-embedded ceramic tablet as a secondary PoUWT method when placed in the lower reservoir of the ceramic water filter system to provide residual disinfection post-filtration. Samples were collected from 79 households over one year and analyzed for turbidity, total silver levels and coliform bacteria. Results show that the silver-embedded ceramic tablet effectively reduced total coliform bacteria (TC) and E. coli when used as a stand-alone PoUWT method and when used in combination with ceramic water filters. The silver-embedded ceramic tablet's performance as a stand-alone PoUWT method was comparable to current inexpensive, single-use PoUWT methods, demonstrating 100% and 75% median reduction in E. coli and TC, respectively, after two months of use. Overall, the the filter-tablet combination performed the best of the three interventions, providing a 100% average percent reduction in E. coli over one year. User surveys were also conducted and indicated that the silver

    The area of Space Health and Medicine is one of the NASA's Space Technology Grand Challenges. Space is an extreme environment which is not conducive to human life. The extraterrestrial environment can result in the deconditioning of various human physiological systems and thus require easy to use physiological monitoring technologies in order to better monitor space crews for appropriate health management and successful space missions and space operations. Furthermore, the Space Technology Roadmap's Technology Area Breakdown Structure calls for improvements in research to support human health and performance (Technology Area 06). To address these needs, this project investigated a potential noncontact and noninvasive radio frequency-based technique of monitoring central hemodynamic function in human research subjects in response to orthostatic stress.

    Full Text Available Technologically modified spinel ceramics are prepared from Al2O3 and 4MgCO3×Mg(OH2×5H2O powders at 1200, 1300 and 1400 oC. The influence of sintering temperature on porous structure and exploitation properties of obtained humidity-sensitive MgO-Al2O3 ceramics are studied. It is shown that increasing of preparing temperature from 1200 to 1400 oC result in transformation of pore size distribution in ceramics from tri- to bi-modal including the open macro- and mesopores with sizes from tem to hundreds nm and nanopores until to a few nm. The studied ceramic elements with electrical resistances ~ 10-2-102 MОhm are high humidity sensitive in the region of 30-95 % with minimal hysteresis in adsorption-desorption cycles. It is established that increasing of humidity sensitivity in ceramics are related to achievement near to optimum pore size distribution and quantity of pores in the all regions. Prolonged degradation transformation in ceramics at higher temperature and relative humidity result in lose sensitivity up to 40-50 %.DOI: http://dx.doi.org/10.5755/j01.ms.21.1.5189

    Piezoelectric ceramic wafers are applied for the excitation and detection of ultrasonic guided waves to determine the health state of plate-like structures. Two PZT wafers, whose diameter is 11mm and thickness is 0.4mm respectively, are bonded permanently on the surface of a 1mm thick aluminum plate. One of these wafers is actuated by sinusoidal tone burst at various frequencies ranging from 100kHz to 500kHz, the other one is used as a receiver for acquiring ultrasonic guided wave signals. According to the amplitudes and shapes of these received signals, guided wave modes and their proper frequency range by using these wafers are determined. For the improvement of the signal-to-noise ratio, the Daubechies wavelet of order 40 is used for signal denoising as the mother wavelet. Furthermore, the detection of an artificial cylindrical through-hole defect is achieved by using S0 at 300kHz. Experimental results show that it is feasible and effective to detect defects in plate-like structures based on ultrasonic guided wave technology by using bonded piezoelectric ceramic wafers.

    2008-12-01

    The word 'ceramics' is derived from the Greek keramos, meaning pottery and porcelain. The opaque and translucent cement and clay often used in tableware are not appropriate for optical applications because of the high content of optical scattering sources, that is, defects. Recently, scientists have shown that by eliminating the defects, a new, refined ceramic material - polycrystalline ceramic - can be produced. This advanced ceramic material offers practical laser generation and is anticipated to be a highly attractive alternative to conventional glass and single-crystal laser technologies in the future. Here we review the history of the development of ceramic lasers, the principle of laser generation based on this material, some typical results achieved with ceramic lasers so far, and discuss the potential future outlook for the field.

    While the emergence of pottery manufacturing is a wide-spread historical occurrence, and one that has garnered the attention of archaeologists for decades, we know very little about how these ancient vessels were created. Through the application of radiographic scanning and computed tomography this paper provides insights into the manufacturing techniques used by the earliest potters in North America. While x-rays have been used to investigate ceramic manufacturing techniques for decades, this paper provides a reassessment of radiography in light of advances in both computed tomography and reconstructive software.

    Full Text Available Transferring inventions of academic scientists to private enterprises for the purpose of commercialization is long known as University-Industry (firm Technology Transfer While the importance of this phenomenon is simultaneously raising in public and private sector, only a part of patented academic inventions succeed in passing the process of commercialization. Despite the fact that formal Technology Transfer process and licencing of patented innovations to third party is the main legal tool for safeguarding rights of academic inventors in commercialization of their inventions, it is not sufficient for transmitting tacit knowledge which is necessary in exploitation of transferred technology. Existence of reciprocal and complementary relations between formal and informal technology transfer process has resulted in formation of different models for university-industry organizational collaboration or even integration where licensee firms keep contact with academic inventors after gaining legal right for commercialization of their patented invention. Current paper argues that despite necessity for patents to legally pass the right of commercialization of an invention, they are not sufficient for complete knowledge transmission in the process of technology transfer. Lack of efficiency of formal mechanism to end the Technology Transfer loop makes an opportunity to create innovative interpersonal and organizational connections among patentee and licensee company. With emphasize on need for further elaboration of informal mechanisms as critical and underappreciated aspect of technology transfer process, article will try to answer the questions of how to optimize knowledge transmission process in the framework of University-Industry Technology Transfer Projects? What is the theoretical basis for university-industry technology transfer process? What are organization collaborative models which can enhance overall performance by improving transmission of

The Project's technical activities were organized into three work elements: (1) The Molecular Modeling and Applied Genetics work element includes research on modeling of biological systems, developing rigorous methods for the prediction of three-dimensional (tertiary) protein structure from the amino acid sequence (primary structure) for designing new biocatalysis, defining kinetic models of biocatalyst reactivity, and developing genetically engineered solutions to the generic technical barriers that preclude widespread application of biocatalysis. (2) The Bioprocess Engineering work element supports efforts in novel bioreactor concepts that are likely to lead to substantially higher levels of reactor productivity, product yields and lower separation energetics. Results of work within this work element will be used to establish the technical feasibility of critical bioprocess monitoring and control subsystems. (3) The Bioprocess Design and Assessment work element attempts to develop procedures (via user-friendly computer software) for assessing the energy-economics of biocatalyzed chemical production processes, and initiation of technology transfer for advanced bioprocesses.

    Commercial aviation relies almost entirely on subsonic fixed wing aircraft to constantly move people and goods from one place to another across the globe. While air travel is an effective means of transportation providing an unmatched combination of speed and range, future subsonic aircraft must improve substantially to meet efficiency and environmental targets.The NASA Fundamental Aeronautics Fixed Wing (FW) Project addresses the comprehensive challenge of enabling revolutionary energy efficiency improvements in subsonic transport aircraft combined with dramatic reductions in harmful emissions and perceived noise to facilitate sustained growth of the air transportation system. Advanced technologies and the development of unconventional aircraft systems offer the potential to achieve these improvements. Multidisciplinary advances are required in aerodynamic efficiency to reduce drag, structural efficiency to reduce aircraft empty weight, and propulsive and thermal efficiency to reduce thrust-specific energy consumption (TSEC) for overall system benefit. Additionally, advances are required to reduce perceived noise without adversely affecting drag, weight, or TSEC, and to reduce harmful emissions without adversely affecting energy efficiency or noise.The paper will highlight the Fixed Wing project vision of revolutionary systems and technologies needed to achieve these challenging goals. Specifically, the primary focus of the FW Project is on the N+3 generation; that is, vehicles that are three generations beyond the current state of the art, requiring mature technology solutions in the 2025-30 timeframe

    The Garrett/Ford Advanced Gas Turbine (AGT101) technology project has made significant progress in the areas of ceramic component design, analysis, and test evaluation using an iterative approach. Design stress limits are being defined for state-of-the-art fine ceramics with good correlation between analytical predictions and empirical results. Recent tests in both rigs and engines are demonstrating the feasibility of high temperature/strength ceramic materials in the gas turbine environment. Component transient stress fields are being defined providing the data base for lower stress/longer life component design. Thermally induced transient stresses to 220 MPa (32 ksi) in reaction bonded silicon nitride (RBSN), 310 Mpa (45 ksi) in sintered alpha silicon carbide (SASC), and 345 MPa (50 ksi) in sintered silicon nitride (SSN) have been successfully demonstrated in AGT101 component screening and qualification test rigs.

    1997-01-09

    This report summarizes the task conducted to examine various activities on interface development for ceramic-matrix composites (CMCs) intended for high-temperature applications. While several articles have been published on the subject of CMC interfaces, the purpose of this report is to describe the various ongoing efforts on interface concepts, material selection, and issues related to processing methods employed for developing interface coatings. The most exciting and new development in the field is the discovery of monazite as a potential interface material for mullite- and alumina-based composites. Monazite offers two critical properties to the CMC system; a weakly bonded layer due to its non-wetting behavior and chemical compatibility with both alumina and mullite up to very high temperatures (> 1,600 C). A description of the Department of Energy-related activities and some thoughts on processing issues, interface testing, and effects of processing on fiber strength are given.

    Performance advantages of the new pilot project technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities. The decision to move forward with funding usually hinges on demonstrating actual cost reductions that can be credited to budgets and thereby truly reduce O&M or capital costs. Technology enhancements, while enhancing work methods and making work more efficient, often fail to eliminate workload such that it changes overall staffing and material cost requirements. It is critical to demonstrate cost reductions or impacts on non-cost performance objectives in order for the business case to justify investment by nuclear operators. The Business Case Methodology (BCM) was developed in September of 2015 to frame the benefit side of II&C technologies to address the “benefit” side of the analysis—as opposed to the cost side—and how the organization evaluates discretionary projects (net present value (NPV), accounting effects of taxes, discount rates, etc.). The cost and analysis side is not particularly difficult for the organization and can usually be determined with a fair amount of precision (not withstanding implementation project cost overruns). It is in determining the “benefits” side of the analysis that utilities have more difficulty in technology projects and that is the focus of this methodology. The methodology is presented in the context of the entire process, but the tool provided is limited to determining the organizational benefits only. This report describes a the use of the BCM in building a business case for mobile work packages, which includes computer-based procedures and other automated elements of a work package. Key to those impacts will be identifying where the savings are

    2008-09-15

    Many components of pump impeller of nuclear power plants is generally made of stainless steel and Al-bronze with superior corrosion resistance to sea water. However, they should be replaced by one- to five-year period because of material damage by a very big cavitation impact load, even though their designed durability is twenty years. Especially, in case of Young-Gwang nuclear power plant located at the west sea, damage of components of pump impeller is so critical due to the additional damage by solid particle erosion and hence their replacement period is very short as several months compared to other nuclear power plants. In addition, it is very difficult to maintain and repair the components of pump impeller since there is no database on the exact durability and damage mechanism. Therefore, in this study, fabrication technology of new advanced materials modified by dispersion of nano-carbide and -oxide ceramics into the matrix is developed first. Secondly, technology to estimate the dynamic damage by solid particle erosion is established and hence applied to the prediction of the service life of the components of pump impeller.

    2004-01-01

    Combustion reaction welding, one promising method to weld ceramics and metals, was used to weld TiB2 and Mo. The results showed that the reacted products through combustion reaction were TiB2 and MoB when the Mo contents in reactants were 20 wt pct and 40 wt pct while there was Mo besides MoB and TiB2 when there were 60 wt pct and 80 wt pct Mo in reactants. Diffusion of elements occurred at the interfaces of the two substrates. The interfaces between the reacted and the two substrates were indistinct after being welded. The welding temperature strongly affected properties of the samples. The value of bending strength of the sample with 80 wt pct Mo in reactant welded at 1500℃ was the highest, 368.52 MPa. The highest value of shear strength among all the samples was that of the one with 40 wt pct Mo in reactant welded at 1500℃, 50.97 MPa.

    2008-04-01

    The Advanced Linked Extended Reconnaissance & Targeting (ALERT) Technology Demonstration (TD) project is addressing many operational needs of the future Canadian Army's Surveillance and Reconnaissance forces. Using the surveillance system of the Coyote reconnaissance vehicle as an experimental platform, the ALERT TD project aims to significantly enhance situational awareness by fusing multi-sensor and tactical data, developing automated processes, and integrating beyond line-of-sight sensing. The project is exploiting important advances made in computer processing capability, displays technology, digital communications, and sensor technology since the design of the original surveillance system. As the major research area within the project, concepts are discussed for displaying and fusing multi-sensor and tactical data within an Enhanced Operator Control Station (EOCS). The sensor data can originate from the Coyote's own visible-band and IR cameras, laser rangefinder, and ground-surveillance radar, as well as from beyond line-of-sight systems such as mini-UAVs and unattended ground sensors. Video-rate image processing has been developed to assist the operator to detect poorly visible targets. As a second major area of research, automatic target cueing capabilities have been added to the system. These include scene change detection, automatic target detection and aided target recognition algorithms processing both IR and visible-band images to draw the operator's attention to possible targets. The merits of incorporating scene change detection algorithms are also discussed. In the area of multi-sensor data fusion, up to Joint Defence Labs level 2 has been demonstrated. The human factors engineering aspects of the user interface in this complex environment are presented, drawing upon multiple user group sessions with military surveillance system operators. The paper concludes with Lessons Learned from the project. The ALERT system has been used in a number of C4ISR

    This paper examines the goals of the Photovoltaic Manufacturing Technology (PVMaT) project and its achievements in recapturing the investment by the photovoltaic (PV) industry and the public in this research. The PVMaT project was initiated in 1990 with the goal of enhancing the world-wide competitiveness of the U.S. PV industry. Based on the authors analysis, PVMaT has contributed to PV module manufacturing process improvements, increased product value, and reductions in the price of today`s PV products. An evaluation of success in this project was conducted using data collected from 10 of the PVMaT industrial participants in late fiscal year (FY) 1995. These data indicate a reduction of 56% in the weighted average module manufacturing costs from 1992 to 1996. During this same period, U.S. module manufacturing capacity has increased by more than a factor of 6. Finally, the analysis indicates that both the public and the manufacturers will recapture the funds expended in R&D manufacturing improvements well before the year 2000.

    Full Text Available Children suffering a serious illness, experience enormous changes in their daily lives. Not only does the direct consequences of the disease affect the child, but also the fact of being at a hospital, or at home and not being allowed to go to school. Frequently, connections with classmates, neighbors, and sometimes even some with his relatives are lost. Furthermore, the responsibility of the state, to continue his schooling process is much harder, since different communities (family, school teachers, hospital teachers, medical doctors, psychologists… have to be coordinated. Last but not least, entertainment and enjoyment should be provided to avoid boredom and to improve their affective state. At the same time, with the development of Information and Communication Technologies, a large number of solutions have arisen that allow people to enhance their communication, education and entertainment possibilities. These technologies seem perfectly suitable to be used to tackle the problems described above. In this article, some of the special necessities of children suffering from a serious illness are pointed out, technologies available to be facilitated are described and some initiatives taking place in Spain mentioned. The SAVEH project will be described in detail.

    Boyle, Timothy J.; Ottley, Leigh Anna M.; Yang, Pin; Chen, Ching-Fong; Sanchez, Margaret R.; Bell, Nelson Simmons

    2008-10-01

    This project uses advanced ceramic processes to fabricate large, optical-quality, polycrystalline lanthanum halide scintillators to replace small single crystals produced by the conventional Bridgman growth method. The new approach not only removes the size constraint imposed by the growth method, but also offers the potential advantages of both reducing manufacturing cost and increasing production rate. The project goal is to fabricate dense lanthanum halide ceramics with a preferred crystal orientation by applying texture engineering and solid-state conversion to reduce the thermal mechanical stress in the ceramic and minimize scintillation light scattering at grain boundaries. Ultimately, this method could deliver the sought-after high sensitivity and <3% energy resolution at 662 keV of lanthanum halide scintillators and unleash their full potential for advanced gamma ray detection, enabling rapid identification of radioactive materials in a variety of practical applications. This report documents processing details from powder synthesis, seed particle growth, to final densification and texture development of cerium doped lanthanum bromide (LaBr{sub 3}:Ce{sup +3}) ceramics. This investigation demonstrated that: (1) A rapid, flexible, cost efficient synthesis method of anhydrous lanthanum halides and their solid solutions was developed. Several batches of ultrafine LaBr{sub 3}:Ce{sup +3} powder, free of oxyhalide, were produced by a rigorously controlled process. (2) Micron size ({approx} 5 {micro}m), platelet shape LaBr{sub 3} seed particles of high purity can be synthesized by a vapor phase transport process. (3) High aspect-ratio seed particles can be effectively aligned in the shear direction in the ceramic matrix, using a rotational shear-forming process. (4) Small size, highly translucent LaBr{sub 3} (0.25-inch diameter, 0.08-inch thick) samples were successfully fabricated by the equal channel angular consolidation process. (5) Large size, high density

    The standard practice for protecting metallic substrates in atmospheric environments is the use of an applied coating system. Current coating systems used across AFSPC and NASA contain volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). These coatings are sUbject to environmental regulations at the Federal and State levels that limit their usage. In addition, these coatings often cannot withstand the high temperatures and exhaust that may be experienced by Air Force Space Command (AFSPC) and NASA structures. In response to these concerns, AFSPC and NASA have approved the use of thermal spray coatings (TSCs). Thermal spray coatings are extremely durable and environmentally friendly coating alternatives, but utilize large cumbersome equipment for application that make the coatings difficult and time consuming to repair. Other concerns include difficulties coating complex geometries and the cost of equipment, training, and materials. Gas Dynamic Spray (GOS) technology (also known as Cold Spray) was evaluated as a smaller, more maneuverable repair method as well as for areas where thermal spray techniques are not as effective. The technology can result in reduced maintenance and thus reduced hazardous materials/wastes associated with current processes. Thermal spray and GOS coatings also have no VOCs and are environmentally preferable coatings. The primary objective of this effort was to demonstrate GDS technology as a repair method for TSCs. The aim was that successful completion of this project would result in approval of GDS technology as a repair method for TSCs at AFSPC and NASA installations to improve corrosion protection at critical systems, facilitate easier maintenance activity, extend maintenance cycles, eliminate flight hardware contamination, and reduce the amount of hazardous waste generated.

    The aim is to create inorganic materials with their functions well harmonized and with their reliability remarkably improved, and efforts are made to establish basic technologies with which structural control may be carried out simultaneously for multiple layers in in-process products through positive utilization of various chemical reactions in the materials synthesizing process. This fiscal year's achievements are stated below. A low-temperature pressure nitriding method is developed in which nitriding reaction directly involves the metal aluminum compact for conversion into ceramics, and an aluminum sintered body is produced capable of high thermal conduction of not less than 170w/mk with the original compact shape retained. By a heat treatment in a high-temperature pressure nitriding atmosphere, a success is attained in producing a silicon nitride ceramic body enhanced (150w/mk) in thermal conduction. It is clarified that the microwave-aided selective heating technology works effectively in enhancing the particle growth rate in a liquid-phase sinter system, and a success is won in increasing strength by virtue of the formation of particle-growing particles.

    In this paper, volcanic-rich ceramic remains from the archaeological sites of Francavilla, Naxos and Taormina (Province of Messina, North-eastern Sicily) were studied by using inclusions as main provenance marker. Technological features, such as temper choice, vitrification degree and firing temperatures, were investigated by polarizing microscopy, X-ray diffractometry (XRD) and scanning electron microscopy (SEM). Information on the production centres was obtained through the identification of the source area of raw materials used as temper. Indeed, petrochemical analysis of the volcanic inclusions within the examined ceramics displayed strong affinities with structures/textures and compositions of the locally outcropping mugearitic products, probably ascribed to the eruptive activity of an eccentric vent of Mt. Etna (Mt. Mojo). A local production for the studied pottery samples has been therefore advanced, assuming that the used volcanic temper was easily available from the alluvial deposits along the Alcantara River stream, which is connected to the lava flow of Mt. Mojo.

    The National Renewable Energy Laboratory (NREL) has a major responsibility in the implementation of the U.S. Department of Energy's (DOE's) Solar Energy Technologies Program. Sandia National Laboratories (SNL) has a major role in supporting inverter development, characterization, standards, certifications, and verifications. The Solar Energy Technologies Program recently published a Multiyear Technical Plan, which establishes a goal of reducing the Levelized Energy Cost (LEC) for photovoltaic (PV) systems to $0.06/kWh by 2020. The Multiyear Technical Plan estimates that, in order to meet the PV system goal, PV inverter prices will need to decline to $0.25-0.30 Wp by 2020. DOE determined the need to conduct a rigorous review of the PV Program's technical and economic targets, including the target set for PV inverters. NREL requested that Navigant Consulting Inc.(NCI) conduct a review of historical and projected cost and performance improvements for PV inverters, including identification of critical barriers identified and the approaches government might use to address them.

    Full Text Available This work aims to evaluate through technological tests the use of quartzite residues as component at the the production of porcelain stoneware. Were collected five samples of quartzites called of green quartzite, black quartzite, pink quartzite, goldy quartzite, white quartzite. After, the raw materials were milled, passed by a sieve with a Mesh of 200# (Mesh and characterized by chemical analysis in fluorescence of x-rays and also analysis of the crystalline phases by diffraction of x-rays. The porcelain tiles mass is composed of five formulations containing 57% of feldspar, 37% of clay and 6% of residues of quartzite with different coloration. For the preparation of the specimens, it was used uniaxial pressing, which afterwards were synthesized at 1150°C, 1200°C and 1250°C. After the sintering, the specimens were submit for tests of technological characterization like: water absorption, linear shrinkage, apparently porosity, density and flexural strain at three points. The results presented in the fluorescence of x-rays showed a high-content of iron oxide on black quartzite that is why it was discarded the utilization of it in porcelain stoneware. All quartzite formulations had low water absorption achieved when synthesized at 1200°C, getting 0.1 to 0.36% without having gone through the atomization process. At the tests of flexural strain, all the quartzite had in acceptance limits, according to the European norm EN 100, overcoming 27 MPA at 1200°C

  9. Proposed Project Selection Method for Human Support Research and Technology Development (HSR&TD)

    Science.gov (United States)

    Jones, Harry

    2005-01-01

    The purpose of HSR&TD is to deliver human support technologies to the Exploration Systems Mission Directorate (ESMD) that will be selected for future missions. This requires identifying promising candidate technologies and advancing them in technology readiness until they are acceptable. HSR&TD must select an may of technology development projects, guide them, and either terminate or continue them, so as to maximize the resulting number of usable advanced human support technologies. This paper proposes an effective project scoring methodology to support managing the HSR&TD project portfolio. Researchers strongly disagree as to what are the best technology project selection methods, or even if there are any proven ones. Technology development is risky and outstanding achievements are rare and unpredictable. There is no simple formula for success. Organizations that are satisfied with their project selection approach typically use a mix of financial, strategic, and scoring methods in an open, established, explicit, formal process. This approach helps to build consensus and develop management insight. It encourages better project proposals by clarifying the desired project attributes. We propose a project scoring technique based on a method previously used in a federal laboratory and supported by recent research. Projects are ranked by their perceived relevance, risk, and return - a new 3 R's. Relevance is the degree to which the project objective supports the HSR&TD goal of developing usable advanced human support technologies. Risk is the estimated probability that the project will achieve its specific objective. Return is the reduction in mission life cycle cost obtained if the project is successful. If the project objective technology performs a new function with no current cost, its return is the estimated cash value of performing the new function. The proposed project selection scoring method includes definitions of the criteria, a project evaluation

    In the framework of a Fusion for Energy (F4E) grant, a test campaign started in 2012 in order to assess the performance of the in-vessel viewing system (IVVS) probe concept and to verify its compatibility when exposed to ITER typical working conditions. ENEA laboratories went through with several tests simulating high magnetic fields, high temperature, high vacuum, gamma radiation and neutron radiation. A customized motor has been adopted to study the performances of ultrasonic piezo motors technology in high magnetic field conditions. This paper reports on the testing activity performed on the motor in a multi Tesla magnetic field. The job was carried out in a test facility of ENEA laboratories able to achieve 14 T. A maximum field of 10 T, fully compliant with ITER requirements (8 T), was applied. A specific mechanical assembly has been designed and manufactured to hold the motor in the region with high homogeneity of the field. Results obtained so far indicate that the motor is compatible with high magnetic fields, and are presented in the paper.

    Three copper systems with relevance to materials technology are discussed. In the first, a CuS precursor, Cu4S1O (4-methylpyridine)(sub 4)- (4-MePy), was prepared by three routes: reaction of Cu2S, reaction of CuBr-SMe2, and oxidation of copper powder with excess sulfur in 4-methylpyridine by sulfur. In the second, copper powder was found to react with excess thiourea (H2NC(S)NH2) in 4-methylpyridine to produce thiocyanate (NCS(-)) complexes. Three isolated and characterized compounds are: Cu(NCS)(4-MePy)(sub 2), a polymer, (4-MePy-H)(Cu(NCS)(sub 3)(4-MePy)(sub 2)), a salt, and t-Cu(NCS)(sub 2)(4-MePy)(sub 4). Finally, an attempt to produce a mixed-metal sulfide precursor of Cu and Ga in N-methylimidazole (N-MeIm) resulted in the synthesis of a Cu-containing polymer, Cu(SO4)(N-MeIm). The structures are presented; the chemistry will be briefly discussed in the context of preparation and processing of copper-containing materials for aerospace applications.

  15. Projects to improve mathematics performance at a university of technology

    2009-09-01

    Full Text Available Lecturers at tertiary institutions have been expressing concern about the quality of students in mathematics for a long time now. Blame is usually placed at the door of secondary schools, but through put figures are still determining state subsidies and as such necessitate institutions to constantly revisit their efforts in terms of improving performance in mathematics. In this article, the results of two studies to improve the mathematics performance at a technical university are reported. The first study took place at the former Technikon Northern Gauteng and was an action research project with an experimental design. The study entailed the implementation of tutorial sessions and it revealed certain traits of tertiary mathematics education. Data were collected through structured observation, questionnaires and focus group interviews. A standardized questionnaire, Study Orientation Questionnaire in Maths (SOM, was introduced and “study habits” was the field in the test that featured most significantly in both the experimental and the control groups. The results revealed, inter alia, that timely assessment is needed to detect and correct misconceptions as soon as possible. It also pointed out that attendance of lectures (and tutorials impacted strongly on performance. Lastly, it was found that students preferred communicating mathematics through the medium of English and not by using their mother tongue. The second project was conducted at the Tshwane University of Technology (TUT and consisted of an investigation into assessment practices in first year mathematics.

    2012-12-31

    Separation of hydrogen from coal gas represents one of the most promising ways to produce alternative sources of fuel. Ceramatec, teamed with CoorsTek and Sandia National Laboratories has developed materials technology for a pressure driven, high temperature proton-electron mixed conducting membrane system to remove hydrogen from the syngas. This system separates high purity hydrogen and isolates high pressure CO{sub 2} as the retentate, which is amenable to low cost capture and transport to storage sites. The team demonstrated a highly efficient, pressure-driven hydrogen separation membrane to generate high purity hydrogen from syngas using a novel ceramic-ceramic composite membrane. Recognizing the benefits and limitations of present membrane systems, the all-ceramic system has been developed to address the key technical challenges related to materials performance under actual operating conditions, while retaining the advantages of thermal and process compatibility offered by the ceramic membranes. The feasibility of the concept has already been demonstrated at Ceramatec. This project developed advanced materials composition for potential integration with water gas shift rectors to maximize the hydrogenproduction.

    Full Text Available Results of research in the mode of preparing molding compositions as one of technological stages in Bulgar pottery production are presented in the article. The subject of study was the common Bulgar ceramics from the Bulgar settlement site of the Golden Horde period (2011-2012 excavations. Four basic functional groups of ceramics were selected: kitchen, transportation, tableware, technical items. The study was conducted with the aim of identifying the dependence of pottery technology on the pottery functional purpose. While analyzing the materials, a complex methodology has been applied: a synthesis of traditional archaeological and natural science methods (A.A. Bobrinsky’s technical and technological method, petrography, X-ray phase analysis. The studies have shown that different functional forms of pottery had generated a variety of approaches to their manufacture. In most cases, special recipes were absent, but a certain differentiation could be traced in the choice of raw materials for the manufacture of vessels for different functional purposes. A further detailed study of the stages associated with raw materials selection and extraction, as well as that of the vessel hollow body design, and the methods of vessel strengthening (drying and firing are in prospect.

    2008-06-01

    The current study aimed at examining the efficacy of technological projects as learning tools by exploring the following questions: the extent to which projects in technology develop students as independent learners; the types of knowledge the students deal with in working on their projects; the role of problem-solving in technological projects; and how projects integrate into traditional schooling. The subjects were 53 high school (12th grade) students who prepared graduating projects in technology under the supervision of nine teachers. Data were collected by observing the students in the laboratory, administrating two questionnaires to both the students and the teachers, and analyzing 25 portfolios prepared by the students of their projects. The findings indicate that projects in technology provide a good opportunity to engage students in challenging tasks that enhance their learning skills. To maximize this potential, it is necessary to employ the project method from the early stages of learning technology. It is especially important that teachers having a strong engineering orientation also acquire pedagogical knowledge on issues such as fostering independent learning, creativity, peer learning and reflective practice in the technological classroom.

  11. Ceramic Processing

    Energy Technology Data Exchange (ETDEWEB)

    EWSUK,KEVIN G.

    1999-11-24

    Ceramics represent a unique class of materials that are distinguished from common metals and plastics by their: (1) high hardness, stiffness, and good wear properties (i.e., abrasion resistance); (2) ability to withstand high temperatures (i.e., refractoriness); (3) chemical durability; and (4) electrical properties that allow them to be electrical insulators, semiconductors, or ionic conductors. Ceramics can be broken down into two general categories, traditional and advanced ceramics. Traditional ceramics include common household products such as clay pots, tiles, pipe, and bricks, porcelain china, sinks, and electrical insulators, and thermally insulating refractory bricks for ovens and fireplaces. Advanced ceramics, also referred to as ''high-tech'' ceramics, include products such as spark plug bodies, piston rings, catalyst supports, and water pump seals for automobiles, thermally insulating tiles for the space shuttle, sodium vapor lamp tubes in streetlights, and the capacitors, resistors, transducers, and varistors in the solid-state electronics we use daily. The major differences between traditional and advanced ceramics are in the processing tolerances and cost. Traditional ceramics are manufactured with inexpensive raw materials, are relatively tolerant of minor process deviations, and are relatively inexpensive. Advanced ceramics are typically made with more refined raw materials and processing to optimize a given property or combination of properties (e.g., mechanical, electrical, dielectric, optical, thermal, physical, and/or magnetic) for a given application. Advanced ceramics generally have improved performance and reliability over traditional ceramics, but are typically more expensive. Additionally, advanced ceramics are typically more sensitive to the chemical and physical defects present in the starting raw materials, or those that are introduced during manufacturing.

    Energy Technology Data Exchange (ETDEWEB)

    Kormanyos, K.R.

    1978-02-01

    Oxide glass--ceramic recuperators for application to automotive gas turbine engines were investigated. Design data and fabrication feasibility were established. Evaluation of glass--ceramic recuperator structures was carried out on a series of experimental test specimens. Parametric design data for plate--fin type glass--ceramic recuperator configurations was developed over a range of engine operating conditions. Recuperator sizing procedures were developed to fit four conceptual recuperator designs to the DOE/Chrysler Baseline regenerated gas turbine engine. Assumed pressure drop and effectiveness value constraints on sizing yielded two design packages with acceptable dimensions to fit an automobile engine compartment. Four conceptual recuperator designs were fabricated as demonstration samples using CER-VIT C-132 glass--ceramic material. Single-pass cross-flow cores were fabricated using CER-VIT C-126 material for laboratory scale tests of cross-circuit leakage and hot-gas flow thermal cycling effects. The laboratory tests precipitated the development effect of a modified material system for test core fabrication. The modified material system proved successful in initial studies on small core sections; however, upon scale up to test core size unacceptably high cross-leakage resulted.

    Full Text Available Since 2009 of global financial crisis, shipbuilding industry has undergone hard times seriously. After such a long depression, the latest global shipping market index shows that the economic recovery of global shipbuilding market is underway. Especially, nations with enormous resources are going to increase their productivity or expanding their shipyards to accommodate a large amount of orders expected in the near future. However, few commercial projects have been carried out for the practical shipyard layout designs even though those can be good commercial opportunities for shipbuilding engineers. Shipbuilding starts with a shipyard construction with a large scale investment initially. Shipyard design and the equipment layout problem, which is directly linked to the productivity of ship production, is an important issue in the production planning of mass production of ships. In many cases, shipbuilding yard design has relied on the experience of the internal engineer, resulting in sporadic and poorly organized processes. Consequently, economic losses and the trial and error involved in such a design process are inevitable problems. The starting point of shipyard construction is to design a shipyard layout. Four kinds of engineering parts required for the shipyard layout design and construction. Those are civil engineering, building engineering, utility engineering and production layout engineering. Among these parts, production layout engineering is most important because its result is used as a foundation of the other engineering parts, and also, determines the shipyard capacity in the shipyard lifecycle. In this paper, the background of shipbuilding industry is explained in terms of engineering works for the recognition of the macro trend.

    2014-10-01

    Full Text Available In face of strong competition, companies in Brazil have increased their financial investments in automation, offering new products and services and reducing operating costs. These companies are focusing their efforts on core competencies and, therefore, they often lack the internal expertise to implement new projects, especially those that bring technological innovation. For this reason, we use the processes of outsourcing or subcontracting to help implement such projects. The unit of analysis in this study is the project and the object of the study to analyze the process of knowledge transfer from a provider to a customer during the duration of the project, which involves new technologies. The main motivation of this work is to address the acquisition and retention of new knowledge related to projects designed for business customers. We have developed a study of three cases of multiple financial firms that buy new technologies and two suppliers of information technology. As a practical result, a management model of knowledge transfer and retention of knowledge in client companies is proposed and incorporated into project management.

This technology enables not only the fabrication of complex three-dimensional structures rapidly and at a realistic cost but also the integration of the elements needed to carry out a whole analytical process, such as pretreatment steps, mixers, and detection systems. In this work, a simple and general procedure for the integration of ion-selective electrodes based on liquid ion exchanger is proposed and illustrated by using ammonium- and nitrate-selective membranes. Additionally, a screen-printed reference electrode was easily incorporated into the microfluidic LTCC structure allowing a complete on-chip integration of the potentiometric detection. Analytical features of the proposed systems are presented.

    Lawrence Berkeley National Laboratory (LBNL) and the Demand Response Research Center (DRRC) performed a technology demonstration and evaluation for Bonneville Power Administration (BPA) in Seattle City Light's (SCL) service territory. This report summarizes the process and results of deploying open automated demand response (OpenADR) in Seattle area with winter morning peaking commercial buildings. The field tests were designed to evaluate the feasibility of deploying fully automated demand response (DR) in four to six sites in the winter and the savings from various building systems. The project started in November of 2008 and lasted 6 months. The methodology for the study included site recruitment, control strategy development, automation system deployment and enhancements, and evaluation of sites participation in DR test events. LBNL subcontracted McKinstry and Akuacom for this project. McKinstry assisted with recruitment, site survey collection, strategy development and overall participant and control vendor management. Akuacom established a new server and enhanced its operations to allow for scheduling winter morning day-of and day-ahead events. Each site signed a Memorandum of Agreement with SCL. SCL offered each site $3,000 for agreeing to participate in the study and an additional $1,000 for each event they participated. Each facility and their control vendor worked with LBNL and McKinstry to select and implement control strategies for DR and developed their automation based on the existing Internet connectivity and building control system. Once the DR strategies were programmed, McKinstry commissioned them before actual test events. McKinstry worked with LBNL to identify control points that can be archived at each facility. For each site LBNL collected meter data and trend logs from the energy management and control system. The communication system allowed the sites to receive day-ahead as well as day-of DR test event signals. Measurement of DR was

  11. A Proposal to Manage Lessons Learned in Projects: Web 2.0 Technologies to Promote Innovation

    2014-06-01

    Full Text Available The web 2.0 is transforming the project management in organizations by improving communication and collaboration. The new generation of web-based collaborative tools provides much better experience than the traditional software package allowing document sharing, integrated task tracking, enforcing team processes and agile planning. Despite of the indubitable benefits brought by web 2.0, the use of these technologies to promote knowledge management remains unexplored. For many project managers to obtain and integrate information from different tools of previous similar projects in global organizations remains a challenge. This theoretical paper presents a proposal that suggests an innovation in the knowledge management area applying web 2.0 technologies. The main goal is to provide an integrated vision of a set of technologies that could be used by organizations in order to promote better management of lessons learned. The proposal includes the lessons learned processes (e.g. capture, share and dissemination, the process-based (e.g. project review and after action review and documentation-based (e.g. micro article and learning histories methods. Results show how web 2.0 technologies can help project managers and team project to cope with the main lessons learned processes and methods to learn from experience. Moreover, recommendations are made for the effective use of web 2.0 components promoting innovation and supporting lessons learned management in projects.Keywords: Project management; Lessons learned processes; lessons learned methods; project learning; web 2.0 technologies; innovation.

  12. Locomotive Emission and Engine Idle Reduction Technology Demonstration Project

    2005-03-14

    In response to a United States Department of Energy (DOE) solicitation, the Maryland Energy Administration (MEA), in partnership with CSX Transportation, Inc. (CSXT), submitted a proposal to DOE to support the demonstration of Auxiliary Power Unit (APU) technology on fifty-six CSXT locomotives. The project purpose was to demonstrate the idle fuel savings, the Nitrous Oxide (NOX) emissions reduction and the noise reduction capabilities of the APU. Fifty-six CSXT Baltimore Division locomotives were equipped with APUs, Engine Run Managers (ERM) and communications equipment to permit GPS tracking and data collection from the locomotives. Throughout the report there is mention of the percent time spent in the State of Maryland. The fifty-six locomotives spent most of their time inside the borders of Maryland and some spent all their time inside the state borders. Usually when a locomotive traveled beyond the Maryland State border it was into an adjoining state. They were divided into four groups according to assignment: (1) Power Unit/Switcher Mate units, (2) Remote Control units, (3) SD50 Pusher units and (4) Other units. The primary data of interest were idle data plus the status of the locomotive--stationary or moving. Also collected were main engine off, idling or working. Idle data were collected by county location, by locomotive status (stationary or moving) and type of idle (Idle 1, main engine idling, APU off; Idle 2, main engine off, APU on; Idle 3, main engine off, APU off; Idle 4, main engine idle, APU on). Desirable main engine idle states are main engine off and APU off or main engine off and APU on. Measuring the time the main engine spends in these desirable states versus the total time it could spend in an engine idling state allows the calculation of Percent Idle Management Effectiveness (%IME). IME is the result of the operation of the APU plus the implementation of CSXT's Warm Weather Shutdown Policy. It is difficult to separate the two. The

    2002-02-26

    This paper describes the organization, planning and initial implementation of a DOE OST program to deploy proven, cost effective technologies into D&D programs throughout the complex. The primary intent is to accelerate closure of the projects thereby saving considerable funds and at the same time being protective of worker health and the environment. Most of the technologies in the ''toolkit'' for this program have been demonstrated at a DOE site as part of a Large Scale Demonstration and Deployment Project (LSDDP). The Mound Tritium D&D LSDDP served as the base program for the technologies being deployed in this project but other LSDDP demonstrated technologies or ready-for-use commercial technologies will also be considered. The project team will evaluate needs provided by site D&D project managers, match technologies against those needs and rank deployments using a criteria listing. After selecting deployments the project will purchase the equipment and provide a deployment engineer to facilitate the technology implementation. Other cost associated with the use of the technology will be borne by the site including operating staff, safety and health reviews etc. A cost and performance report will be prepared following the deployment to document the results.

    The metal oxide polymeric methyltrioxorhenium [(CH3)xReO3] is an unique epresentative of a layered inherent conducting organometallic polymer which adopts the structural motifs of classical perovskites in two dimensions (2D) in form of methyl-deficient, corner-sharing ReO5(CH3) octahedra. In order to improve the characteristics of polymeric methyltrioxorhenium with respect to its physical properties and potential usage as an inherentconducting polymer we tried to optimise the synthetic routes of polymeric modifications of 1 to obtain a sintered ceramic material, denoted ceramic MTO. Ceramic MTO formed in a solvent-free synthesis via auto-polymerisation and subsequent sintering processing displays clearly different mechanical and physical properties from polymeric MTO synthesised in aqueous solution. Ceramic MTO is shown to display activated Re-C and Re=O bonds relative to MTO. These electronic and structural characteristics of ceramic MTO are also reflected by a different chemical reactivity compared with its...

    Ceramic microspheres were prepared by using Chinese bauxite as raw materials through the centrifugal spray drying method. The control technology of microsphere size, degree of sphericity was researched. The ceramic microspheres were sintered by a double sintering process. The microstructure and composition of ceramic microsphere were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray energy spectroscopy. The results show that the degree of sphericity of the ceramic microsphere was good and the particle size was 10-100 μm. The XRD analysis reveals that the main crystalline phase of the ceramic microsphere was α- Al2O3 and mullite (3Al2O3·2SiO2). The product can be used as reinforced material for composite material, especially for antiskid and hard wearing aluminum alloy coating.

    1998-12-31

    This is the final report of a two-year, Laboratory Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL). Functionally graded material is an enabling technology for lightweight body armor improvements. The objective was to demonstrate the ability to produce functionally graded ceramic-polymer and ceramic-metal lightweight armor materials. This objective involved two aspects. The first and key aspect was the development of graded-porosity boron-carbide ceramic microstructures. The second aspect was the development of techniques for liquid infiltration of lightweight metals and polymers into the graded-porosity ceramic. The authors were successful in synthesizing boron-carbide ceramic microstructures with graded porosity. These graded-porosity boron-carbide hot-pressed pieces were then successfully liquid-infiltrated in vacuum with molten aluminum at 1,300 C, and with liquid polymers at room temperature. Thus, they were able to demonstrate the feasibility of producing boron carbide-aluminum and boron carbide-polymer functionally graded materials.

    In the state of Para, the red ceramic industry has several segments highly generators of jobs and a strong social appeal. With so many companies focused on this productive sector emerge, but many without any administration quality. Therefore, this study focused the technological and mineralogical characterization of the raw material used in the manufacture of ceramic blocks, by Ceramica Vermelha Company, located in the district of Inhangapi-PA. The raw material was obtained by the techniques of X-ray diffraction (XRD) to determine the present crystalline phases through an accurate and efficient procedure, where it was possible to identify the peaks relating to montmorillonite, illite and kaolinite clay in the sample, and kaolinite and quartz in the sample laterite. Another important result was the absorption of water, with average satisfactory according to the standards. According to a sieve analysis, the laterite the sand fraction showed a greater extent compared to the other, while the clay silt exceeding 80% was found to be too plastic material. The resistance to compression, the results were below the required by the standard, suggesting more accurate test methods. (author)

    Full Text Available Purpose: Development of a practitioner oriented diagnostic framework and health check tool to support the robust assessment of engineering and technology projects.Design/methodology/approach: The research is based on a literature review that draws together insights on project assessment and critical success factors to establish an integrated systems view of projects. This is extended to allow a comprehensive diagnostic framework to be developed along with a high-level health check tool that can be readily deployed on projects. The utility of the diagnostic framework and health check tool are explored through three illustrative case studies, with two from Canada and one from the United Kingdom. Findings andOriginality/value: The performance of engineering and technology projects can be viewed through a systems perspective and being a function of six sub-systems that are: process, technology, resources, impact, knowledge and culture. The diagnostic framework that is developed through this research integrates these sub-systems to provide a comprehensive assessment methodology for projects, which is linked to existing best practice for project reviews, performance management and maturity models. The case studies provide managerial insights that are related to the diagnostic framework but crucially also position the approach in the context of industrial applications for construction engineering and technology management.Research limitations/implications: The case study approach includes two case studies from the construction and facilities development sector with the third case study from the research and technology sector. Further work is required to investigate the use of the diagnostic framework and health check tool in other sectors.Practical implications: The health check tool will be of practical benefit to new projects managers that require access to a robust and convenient project review methodology for assessing the status and health of a

    This paper carries out a questionnaire survey of persons in charge of the agricultural project in the " Eleventh Five-Year National Support Program" on the level of innovation in projects and the factors influencing innovation. After the linear regression analysis of the survey data,it is found that the factors influencing the innovation in agricultural science and technology projects include the level of innovation in scientific achievements,efficiency of research methods and creation of innovation environment. Through the variance analysis of the level of innovation and its influencing factors related to different innovators,it is found that there are differences in the statistical significance of level of innovation in projects among universities,research institutes,research and extension departments directly under the government,and enterprises; there are no significant differences in the understanding of factors influencing innovation,that is,different innovators basically have the same understanding of factors influencing innovation,but the assessment on level of innovation in projects completed is different to some extent.On this basis,this paper proposes the recommendations for further strengthening the level of innovation in agricultural science and technology projects in order to provide a theoretical reference and practical basis for the project managers to effectively improve the level of agricultural science and technology project management,and enhance the level of innovation in projects.

    This paper describes development of synergy ceramics. In developing a technology to design property fusion processes, studies were made on control of nano-structures by using a high-order nano-structure process, and on evaluation of micro region properties. Such nanocomposite bodies were selected for the object as piezoelectric ceramics PZT group (which increases mechanical characteristics and durability without impeding electric characteristics) and alumina-group YAG (which enhances high-temperature strength). Three-dimensional analyses were performed on particle morphology and crack structures by using focusing ion beams as a study on destruction behavior by means of microscopic and macroscopic particle morphology control. This paper reports the achievements of research and development on control of continuous small pore morphology (uni-directionally pierced pores on a new-type low expansion material used as matrix), intra-particle interface (discusses methods to micronize silicon nitride ceramics tissues), intra-layer interface (oxide-based ceramics are laminated on surface to improve oxidation and heat resistance without impeding high-temperature mechanical properties of non-oxide-based ceramics), intra-layer boundary (Pb-based double composition piezoelectric body having stable layer interface), and boundaries between inorganic and organic matters.

    1991-12-01

    At the US Army Hohenfels Training Area in Germany, more than 30 years of continuous and intensive tactical training has caused extensive environmental damage because of the loss of vegetative cover and accelerated soil erosion. A project was conducted to evaluate the cost-effectiveness and relative benefits of various revegetation procedures. These procedures involved amendment and seedbed preparation options that were combined with three different durations of site closure. The point-intercept method was used to measure the types and amounts of vegetation established and changes in the vegetative community. Over three growing seasons, applications of fertilizer and seed increased the percent grass, legume, and total vegetative cover. The duration of site closure had no influence on the types or amounts of ground cover established. Materials made up only 10% of the total cost of the fertilization and seeding operations. The results of the research indicate that less expensive methods of amendment application should be evaluated. The data also show that site closure is not practical, economical, or necessary. The results of this project suggest that a regular maintenance program consisting of seeding and fertilization is required to maintain adequate vegetative cover and control erosion on tactical training areas.

Each new technology is heralded as the one that will finally take us to the fully electronic Utopia. However, the use of computers as document preparation tools has actually increased the number of paper documents. The latest mass-market development, the Internet, is unlikely to buck this trend even though the tools used seem to encourage on-screen browsing. The problems inherent with screen presentation have not gone away, while the amount of information available to the average computer user is increasing all the time.

  7. LNG - Status in Denmark. Technology and potential. Project report

    2012-05-15

    The interest for LNG both on a small and a large scale is increasing worldwide. The experiences and knowledge on LNG is limited in Denmark. The Danish gas companies' Technical Management Group (TCG) has asked for a status report including a technology description and an evaluation of the potential in Denmark. A survey of primarily small-scale LNG technology is done in the report. The focus is motivated by the new areas of gas utilisation that become possible with small-scale LNG. Small-scale LNG in this study is defined as LNG stored and used at the application or in an isolated gas grid. The small-scale use of LNG has today an almost negligible share of the total LNG trade but offers interesting new applications for gas utilisation. LNG on a small scale can be used primarily as: 1) Ship fuel. 2) Truck fuel (heavy duty long distance). 3) Individual users not connected to the natural gas grid. 4) Backup for upgraded biogas to individual users and vehicle fleets. 5) Security of supply or supply enhancement of heavily loaded parts of the gas grid. 6) Small-scale storage and/or peak shaving. All but the first topics are natural uses for the current Danish gas distributors. LNG as ship fuel may engage other specialized LNG companies. The report contains a technical description of the parts in primarily small-scale LNG handling and operation. Liquefaction, transport, storage, engine technologies, gas quality and safety aspects related to LNG are covered. There seem to be two more or less separate paths for LNG in Denmark, onshore and off-shore use. These are not, apparently, sharing their experiences and knowledge. Rules and regulations are also different which may create some problems in the interface, for example ship bunkering. Further studies are suggested in the area of gas quality and engine technologies and adaptation of foreign guidelines for small-scale installations to Danish conditions. These guidelines ought to be based on international standards and

    The Lawrence Berkeley National Laboratory (LBNL) Demand Response Research Center (DRRC) demonstrated and evaluated open automated demand response (OpenADR) communication infrastructure to reduce winter morning and summer afternoon peak electricity demand in commercial buildings the Seattle area. LBNL performed this demonstration for the Bonneville Power Administration (BPA) in the Seattle City Light (SCL) service territory at five sites: Seattle Municipal Tower, Seattle University, McKinstry, and two Target stores. This report describes the process and results of the demonstration. OpenADR is an information exchange model that uses a client-server architecture to automate demand-response (DR) programs. These field tests evaluated the feasibility of deploying fully automated DR during both winter and summer peak periods. DR savings were evaluated for several building systems and control strategies. This project studied DR during hot summer afternoons and cold winter mornings, both periods when electricity demand is typically high. This is the DRRC project team's first experience using automation for year-round DR resources and evaluating the flexibility of commercial buildings end-use loads to participate in DR in dual-peaking climates. The lessons learned contribute to understanding end-use loads that are suitable for dispatch at different times of the year. The project was funded by BPA and SCL. BPA is a U.S. Department of Energy agency headquartered in Portland, Oregon and serving the Pacific Northwest. BPA operates an electricity transmission system and markets wholesale electrical power at cost from federal dams, one non-federal nuclear plant, and other non-federal hydroelectric and wind energy generation facilities.

    Since April 2001, the Oklahoma City National Memorial Institute for the Prevention of Terrorism has funded an effort by Hicks &Associates, Inc. and the Terrorism Research Center, Inc., aimed ultimately at improving local, state, and federal emergency responders" capabilities for mitigating the effects of chemical, biological, radiological, nuclear or explosive/ incendiary (CBRNE) terrorism. This effort, titled "Project Responder," began by developing an understanding of how state and local responders view their current capabilities, shortfalls, and needs. This paper discusses some of the results of this first phase of the effort that has resulted in a comprehensive report titled "Emergency Responders" Needs, Goals, and Priorities." This paper addresses two of the capabilities from that report which we believe are of most interest to this conference. There are ten other capabilities discussed in the report, which may also be of interest.

  12. A framework for identifying the applicability of heating or cooling technologies based on initial project information

    Science.gov (United States)

    Cacace, Katie Meng

    In order to fully achieve the energy savings and human comfort benefits of many alternative heating and cooling technologies, design considerations for these technologies must be made during the conceptual design stage. However, at this stage architects are often faced with challenges that inhibit the integration of such technologies. At the early stages of design, architects have limited time and technical knowledge to research alternative technologies and mechanical engineers are typically not yet part of the design team to offer their expertise. To address these problems, this research developed a framework for a Technology Identifier that would inform an architect about alternative heating and cooling technologies that are applicable to their specific project at the conceptual design stage. The framework is based on the premise that a quantitative relationship between the initial project information and a technology's critical output variable(s) for heat transfer to the space can be established. Therefore, to be included in the framework a technology must possess a component that provides direct heat transfer to the space for the framework to determine if the technology can maintain the desired space temperature. The climatic influences on a technology's performance and the effect of changing a technology's input variables on the heat transfer output variable(s) were also quantified. Existing building energy simulation programs were used in these analyses. The framework develops simulation input files for multiple technologies, utilizes existing simulation programs to predict the performance of these technologies, and then displays the output results along with other information that is useful to designers at the conceptual stage. Each simulation input file is compiled from a template that queries databases and requires minimal user input. The output display includes the space temperature, energy consumption, and design considerations of each technology. A

  13. Decontamination Technologies, Task 3, Urban Remediation and Response Project

    Energy Technology Data Exchange (ETDEWEB)

    Heiser,J.; Sullivan, T.

    2009-06-30

    In the aftermath of a Radiological Dispersal Device (RDD, also known as a dirty bomb) it will be necessary to remediate the site including building exteriors and interiors, equipment, pavement, vehicles, personal items etc. Remediation will remove or reduce radioactive contamination from the area using a combination of removing and disposing of many assets (including possible demolition of buildings), decontaminating and returning to service other assets, and fixing in place or leaving in place contamination that is deemed 'acceptable'. The later will require setting acceptable dose standards, which will require negotiation with all involved parties and a balance of risk and cost to benefit. To accomplish the first two, disposal or decontamination, a combination of technologies will be deployed that can be loosely classified as: Decontamination; Equipment removal and size reduction; and Demolition. This report will deal only with the decontamination technologies that will be used to return assets to service or to reduce waste disposal. It will not discuss demolition, size reduction or removal technologies or equipment (e.g., backhoe mounted rams, rock splitter, paving breakers and chipping hammers, etc.). As defined by the DOE (1994), decontamination is removal of radiological contamination from the surfaces of facilities and equipment. Expertise in this field comes primarily from the operation and decommissioning of DOE and commercial nuclear facilities as well as a small amount of ongoing research and development closely related to RDD decontamination. Information related to decontamination of fields, buildings, and public spaces resulting from the Goiania and Chernobyl incidents were also reviewed and provide some meaningful insight into decontamination at major urban areas. In order to proceed with decontamination, the item being processed needs to have an intrinsic value that exceeds the cost of the cleaning and justifies the exposure of any workers

  14. Microwave sintering of ceramic materials

    Karayannis, V. G.

    2016-11-01

    In the present study, the potential of microwave irradiation as an innovative energy- efficient alternative to conventional heating technologies in ceramic manufacturing is reviewed, addressing the advantages/disadvantages, while also commenting on future applications of possible commercial interest. Ceramic materials have been extensively studied and used due to several advantages they exhibit. Sintering ceramics using microwave radiation, a novel technology widely employed in various fields, can be an efficient, economic and environmentally-friendlier approach, to improve the consolidation efficiency and reduce the processing cycle-time, in order to attain substantial energy and cost savings. Microwave sintering provides efficient internal heating, as energy is supplied directly and penetrates the material. Since energy transfer occurs at a molecular level, heat is generated throughout the material, thus avoiding significant temperature gradients between the surface and the interior, which are frequently encountered at high heating rates upon conventional sintering. Thus, rapid, volumetric and uniform heating of various raw materials and secondary resources for ceramic production is possible, with limited grain coarsening, leading to accelerated densification, and uniform and fine-grained microstructures, with enhanced mechanical performance. This is particularly important for manufacturing large-size ceramic products of quality, and also for specialty ceramic materials such as bioceramics and electroceramics. Critical parameters for the process optimization, including the electromagnetic field distribution, microwave-material interaction, heat transfer mechanisms and material transformations, should be taken into consideration.

    The safeguards implemented by the International Atomic Energy Agency (IAEA) are of major importance to the non-proliferation objectives of the United States of America and other nations of the world. Assurance of safeguards effectiveness is mandatory to continued peaceful use of nuclear power. To enhance the ability of the IAEA to apply safeguards effectively, and to ensure that the IAEA does not lack technical assistance in critical areas, the US Congress has made available a special authorization for a Program for Technical Assistance to IAEA Safeguards (POTAS). This substantial program of technology transfer was initiated in 1976. The United States Departments of State and Energy, the Arms control and Disarmament Agency and the Nuclear Regulatory Commission have each accepted responsibility for parts of the Program for Technical Assistance to IAEA Safeguards. Funding is provided by state through the Foreign Assistance Act. This report provides a discussion of this program.

    Full Text Available Problem statement: Achieving projects is primordial in the process of teaching in several disciplines, particularly software engineering courses. However, proposing this learning activity in a context of e-learning is not automatically guaranteed by the current platforms, even unsupported by the existing standards for creating educational content. Approach: Through this study, starting from the model developed in the “XESOP-Jaxe” project to represent the contents of an e-learning course, we tried to propose an improvement in order to formalize a project for learners as a learning object. Results: We grafted our model, formalized in XML Schema, to the “XESOP-Jaxe” schema of the course. Thus, to the elements that could constitute a course, comes a new element called “projet” (project. Conclusion: This model was built and tested within the “XESOP-Jaxe” platform whose goal is to provide an effective solution for creating educational content in compliance with existing standards.

    Wolverine Power Supply Cooperative Inc, a member owned cooperative utility based in Cadillac Michigan, proposes to demonstrate the capture, beneficial utilization and storage of CO{sub 2} in the expansion of existing Enhanced Oil Recovery operations. This project is being proposed in response to the US Department of Energy Solicitation DE-FOA-0000015 Section III D, 'Large Scale Industrial CCS projects from Industrial Sources' Technology Area 1. The project will remove 1,000 metric tons per day of CO{sub 2} from the Wolverine Clean Energy Venture 600 MW CFB power plant owned and operated by WPC. CO{sub 2} from the flue gas will be captured using Hitachi's CO{sub 2} capture system and advanced amine technology. The capture system with the advanced amine-based solvent supplied by Hitachi is expected to significantly reduce the cost and energy requirements of CO{sub 2} capture compared to current technologies. The captured CO{sub 2} will be compressed and transported for Enhanced Oil Recovery and CO{sub 2} storage purposes. Enhanced Oil Recovery is a proven concept, widely used to recover otherwise inaccessible petroleum reserves. While post-combustion CO{sub 2} capture technologies have been tested at the pilot scale on coal power plant flue gas, they have not yet been demonstrated at a commercial scale and integrated with EOR and storage operations. Amine-based CO{sub 2} capture is the leading technology expected to be available commercially within this decade to enable CCS for utility and industrial facilities firing coal and waste fuels such as petroleum coke. However, traditional CO{sub 2} capture process utilizing commercial amine solvents is very energy intensive for regeneration and is also susceptible to solvent degradation by oxygen as well as SOx and NO{sub 2} in the flue gas, resulting in large operating costs. The large volume of combustion flue gas with its low CO{sub 2} concentration requires large equipment sizes, which together with the

    1996-06-01

    A transport combustor is being commissioned at the Southern Services facility in Wilsonville, Alabama to provide a gaseous product for the assessment of hot-gas filtering systems. One of the barrier filters incorporates a ceramic tubesheet to support candle filters. The ceramic tubesheet, designed and manufactured by Industrial Filter and Pump Manufacturing Company (EF&PM), is unique and offers distinct advantages over metallic systems in terms of density, resistance to corrosion, and resistance to creep at operating temperatures above 815{degrees}C (1500{degrees}F). Nevertheless, the operational requirements of the ceramic tubesheet are severe. The tubesheet is almost 1.5 m in (55 in.) in diameter, has many penetrations, and must support the weight of the ceramic filters, coal ash accumulation, and a pressure drop (one atmosphere). Further, thermal stresses related to steady state and transient conditions will occur. To gain a better understanding of the structural performance limitations, a contract was placed with Mallett Technology, Inc. to perform a thermal and structural analysis of the tubesheet design. The design analysis specification and a preliminary design analysis were completed in the early part of 1995. The analyses indicated that modifications to the design were necessary to reduce thermal stress, and it was necessary to complete the redesign before the final thermal/mechanical analysis could be undertaken. The preliminary analysis identified the need to confirm that the physical and mechanical properties data used in the design were representative of the material in the tubesheet. Subsequently, few exploratory tests were performed at ORNL to evaluate the ceramic structural material.

    The current emphasis on computer technology integration and narrowing of the curriculum has displaced arts and crafts. However, the hands-on, concrete nature of craft work in science modeling enables students to understand difficult concepts and to be engaged and motivated while learning spatial, logical, and sequential thinking skills. Analogy use is also helpful in understanding unfamiliar, complex science concepts. This study of 28 academically advanced elementary to middle-school students examined student work and perceptions during a science unit focused on four fossil organisms: crinoid, brachiopod, horn coral and trilobite. The study compared: (1) analogy-focused instruction to independent Internet research and (2) computer technology-rich products to crafts-based products. Findings indicate student products were more creative after analogy-based instruction and when made using technology. However, students expressed a strong desire to engage in additional craft work after making craft products and enjoyed making crafts more after analogy-focused instruction. Additionally, more science content was found in the craft products than the technology-rich products. Students expressed a particular liking for two of the fossil organisms because they had been modeled with crafts. The authors recommend that room should be retained for crafts in the science curriculum to model science concepts.

    This project has been oriented toward the development of a commercially viable ceramic membrane for high temperature gas separations. A technically and commercially viable high temperature gas separation membrane and process has been developed under this project. The lab and field tests have demonstrated the operational stability, both performance and material, of the gas separation thin film, deposited upon the ceramic membrane developed. This performance reliability is built upon the ceramic membrane developed under this project as a substrate for elevated temperature operation. A comprehensive product development approach has been taken to produce an economically viable ceramic substrate, gas selective thin film and the module required to house the innovative membranes for the elevated temperature operation. Field tests have been performed to demonstrate the technical and commercial viability for (i) energy and water recovery from boiler flue gases, and (ii) hydrogen recovery from refinery waste streams using the membrane/module product developed under this project. Active commercializations effort teaming with key industrial OEMs and end users is currently underway for these applications. In addition, the gas separation membrane developed under this project has demonstrated its economical viability for the CO2 removal from subquality natural gas and landfill gas, although performance stability at the elevated temperature remains to be confirmed in the field.

    This paper summarizes the general survey mainly conducted by FCRA (Fine Ceramics Research Association) in fiscal 1996, and the joint research results with some universities, from some R and D on synergy ceramics. Silicon nitride based ceramics expressed the same high thermal conductivity as metal by seed crystal addition, grain growth control and orientation control of sheet lamination. For its practical use, study was made on control factors of material, formation and sintering. Ca2Y2Si2O9 single crystal was prepared by float-zone method to determine its crystal structure. No volume change due to high-temperature phase transition as thermal expansion was found. In carbothermal reduction- nitridation of SiO2, addition of Si3N4 seed powder increased a reaction rate and formed uniform particles with an isotropic shape. An average particle size was dependent on the size and number of fine particles in seed powder. Addition of both Si3N4 and Fe compound could change a particle shape from a spherical grain to an elongated grain. A spherical Fe-Si metal grain was found on the tip of an elongated grain. 66 refs., 73 figs., 13 tabs.

    , sulfates/sulfides, chlorides, fluorides, volatile radionuclides or other aqueous components. The FBSR technology can process these wastes into a crystalline ceramic (mineral) waste form. The mineral waste form that is produced by co-processing waste with kaolin clay in an FBSR process has been shown to be as durable as LAW glass. Monolithing of the granular FBSR product, which is one of the objectives of this current study, is being investigated to prevent dispersion during transport or burial/storage but is not necessary for performance. FBSR testing of a Hanford LAW simulant and a WTP-SW simulant at the pilot scale was performed by THOR Treatment Technologies, LLC at Hazen Research Inc. in April/May 2008. The Hanford LAW simulant was the Rassat 68 tank blend and the target concentrations for the LAW was increased by a factor of 10 for Sb, As, Ag, Cd, and Tl; 100 for Ba and Re (Tc surrogate); 1,000 for I; and 254,902 for Cs based on discussions with the DOE field office and the environmental regulators and an evaluation of the Hanford Tank Waste Envelopes A, B, and C. It was determined through the evaluation of the actual tank waste metals concentrations that some metal levels were not sufficient to achieve reliable detection in the off-gas sampling. Therefore, the identified metals concentrations were increased in the Rassat simulant processed by TTT at HRI to ensure detection and enable calculation of system removal efficiencies, product retention efficiencies, and mass balance closure without regard to potential results of those determinations or impacts on product durability response such as Toxicity Characteristic Leach Procedure (TCLP). A WTP-SW simulant based on melter off-gas analyses from Vitreous State Laboratory (VSL) was also tested at HRI in the 15-inch diameter Engineering Scale Test Demonstration (ESTD) dual reformer at HRI in 2008.

    Full Text Available Many sources such as the immaturity, complexity and unpredictable evolution of the technologies themselves, and the difficulty of predicting the market demand generally cause uncertainty in the Information Technology (IT projects. Managerial flexibility has value in the context of uncertain IT projects, as management can continuously gather information about uncertain project and market characteristics and, based on this information, change its course of action. As traditional capital budgeting (or project appraisal approaches fail to consider embedded managerial flexibility in projects, the new investment evaluation approach called “real options” has come on the scene recently. “Options thinking,” an emerging investment management philosophy based on the theory of financial options can provide a promising foundation for hedging the risks under uncertainty. This paper aims at analyzing a real IT investment having growth opportunities by using real options approach. Specifically, the value of investing in a software project as well as embedded flexibility in this opportunity is modeled as an option contract. The expected costs required for completing the project and thereafter the resulting asset value are considered as the base-case parameters of this contract. Option values derived from Binomial method are used for evaluating the project and the optimal investment policy is determined based on these values. As a result, it is shown that the value of an IT project having flexibility can differ from one obtained with traditional capital budgeting methods and a rejected project which was seen as unprofitable before can turn a profitable one through embedded flexibilities.

    1995-10-20

    The Spent Nuclear Fuel Project (SNFP) has undertaken technology acquisition activities focused on supporting the technical basis for the removal of the N Reactor fuel from the K Basins to an interim storage facility. The purpose of these technology acquisition activities has been to identify technology issues impacting design or safety approval, to establish the strategy for obtaining the necessary information through either existing project activities, or the assignment of new work. A set of specific path options has been identified for each major action proposed for placing the N Reactor fuel into a ``stabilized`` form for interim storage as part of this refined technical basis. This report summarizes the status of technology information acquisition as it relates to key decisions impacting the selection of specific path options. The following specific categories were chosen to characterize and partition the technology information status: hydride issues and ignition, corrosion, hydrogen generation, drying and conditioning, thermal performance, criticality and materials accountability, canister/fuel particulate behavior, and MCO integrity. This report represents a preliminary assessment of the technology information supporting the SNFP. As our understanding of the N Reactor fuel performance develops the technology information supporting the SNFP will be updated and documented in later revisions to this report. Revision 1 represents the incorporation of peer review comments into the original document. The substantive evolution in our understanding of the technical status for the SNFP (except section 3) since July 1995 have not been incorporated into this revision.

    We report the qualitative and quantitative results of incorporating interdisciplinary application projects and increasing the use of teaching with technology into Calculus I, II and III at the University of Colorado Denver. Minimal changes were made to the curriculum and minimal time was required of instructors to make the changes. Instructors were given one 3-hour introduction to teaching with technology, a 3-hour introduction to one or two interdisciplinary problems to be used in the class, and course instructors met with each other no more than 1 hour per week. To evaluate the effectiveness of these modifications, 24 students were interviewed four times during a 2 year time span, student comments from student evaluations regarding the application projects were recorded, and the grade-point averages (GPAs) of four groups of 40 students for the year following their completion of Calculus III were analysed. The results show that students' enthusiasm and interest in interdisciplinary application projects were greater when the projects were enthusiastically endorsed by the instructor, but even with mixed instructor enthusiasm, incorporating application projects and increasing the use of technology in the classroom increase the well-roundedness of students' education and increase their performance in more advanced courses as measured by their overall GPA for the year following their Calculus III math class.

    Full text: It is widely acknowledged that the use of renewable energy may assist developing countries as a whole and Small Island States in particular, in addressing their energy needs and at the same time reducing their dependence on fossil fuels. In order to support these efforts, the project Small Developing Island Renewable Energy Knowledge and Technology Transfer Network (DIREKT) is being undertaken. DIREKT is a cooperation scheme involving universities from Germany, Fiji, Mauritius and Trinidad et Tobago with the aim of strengthening their science and technology capacity in the field of renewable energy, by means of technology transfer, information exchange and networking. Developing countries are especially vulnerable to problems associated with climate change and much can be gained by raising their capacity in the field of renewable energy, which is a key area. This paper introduces the project DIREKT, its aims and the partnership. It will also show how sustainable cooperation between the science and technology communities of ACP and EU institutions in the key area of Renewable Energy may be achieved, which is of great relevance for the socio-economic development of small island developing states. One of features of the project, namely the establishment of Research and Technology Transfer Centres within each of the partner countries, will be presented. (Author)

    Full Text Available The necessity to form and develop future technology teachers’ creative abilities has been stressed in the article. The psychologic-pedagogical researches of the leading specialists from Europe, the USA and Japan in the field of creative work and creativity have been analyzed. The main problems of the creative artistic-projective abilities development have been determined based on the analysis and synthesis of foreign and native philosophic, pedagogical and psychological literature dedicated to characteristics of such notions as “creative work” and “creativity”. Approaches and conceptions providing students – future technology teachers – with creative activities have been singled out. The gist of psychological mechanism for forming teachers’ creative personality has been established and its basic features have been determined as a result of the world experience of the theory and methods of creative abilities development generalization. The main features are as follows: an independence and an inclination towards divergent behavior; flexibility of thinking and readiness for everything new; motivation for self-actualization; striving for self-expressing and ability to creative work; ability to find out how to set and solve the problems. It has been mentioned that the technology teachers’ artistic-projective activity requires their creative abilities development, which, in their turn, are formed on the ground of well-developed general and special (art, projective, technological, pedagogical potencies. Therefore, the effectiveness of the students’ art-projective knowledge and skills forming depends upon the extent their general, special and creative abilities have been developed. That is why skillful and pedagogically correct organization of future technology teachers’ artistic-projective activities will inevitably provide the higher qualitatively new level of their creative abilities and creativity.

    1. Present status: Ceramic matrix composites (CMCs: C/SiC and SiC/SiC) do not have sufficient life time above 500 C in power production (turbines, heat exchangers) due to the oxygen sensible C- and SiC-fibres used in such ceramics. 2. Reasoning and goals: SiBNC-fibre have, produced on lab scale, shown excellent stability against oxygen up to temperatures of about 1400 C. The project had the goal to use these fibres for the manufacturing of high temperature resistant CMC and to develop, together with applicants, prototype components (turbine combustion chamber shindles, heat exchanger tubes). 3. Method: Phase 1: Proof of high temperature capabilities of CMC samples manufactured by CVI- and LPI-techniques (CVI=Chemical vapour infiltration, LPI=Liquid polymer infiltration). Phase 2: Development of prototype components together with applicants. 4. Results and Conclusions: The development of fibre manufacturing in technical quantities to be performed in a programme running parallel to this one did not succeed in the quality wanted and necessary. The CMC samples did not show sufficient improvements of high temperature properties. Further fundamental research is necessary before an application with long time high temperature loads can be considered. (orig.) [German] 1.

    This project has successfully developed a practical and reliable method for fabricating SiC ceramic-ceramic joints. This joining method will permit the use of SiC-based ceramics in a variety of elevated temperature fossil energy applications. The technique is based on a reaction bonding approach that provides joint interlayers compatible with SiC, and excellent joint mechanical properties at temperatures exceeding 1000{degrees}C. Recent emphasis has been given to technology transfer activities, and several collaborative research efforts are in progress. Investigations are focusing on applying the joining method to sintered {alpha}-SiC and fiber-reinforced SiC/SiC composites for use in applications such as heat exchangers, radiant burners and gas turbine components.

    The Fire Prevention, Detection, and Suppression (FPDS) project is a technology development effort within the Exploration Technology Development Program of the Exploration System Missions Directorate (ESMD) that addresses all aspects of fire safety aboard manned exploration systems. The overarching goal for work in the FPDS area is to develop technologies that will ensure crew health and safety on exploration missions by reducing the likelihood of a fire, or, if one does occur, minimizing the risk to the crew, mission, or system. This is accomplished by addressing the areas of (1) fire prevention and material flammability, (2) fire signatures and detection, and (3) fire suppression and response. This report describes the outcomes of this project from the formation of the Exploration Technology Development Program (ETDP) in October 2005 to September 31, 2010 when the Exploration Technology Development Program was replaced by the Enabling Technology Development and Demonstration Program. NASA s fire safety work will continue under this new program and will build upon the accomplishments described herein.

    In this paper, we report on the major accomplishments of the U.S. Department of Energy's (DOE) Solar Energy Technologies Program (SETP) Photovoltaic (PV) Technology Incubator project. The Incubator project facilitates a company's transition from developing a solar cell or PV module prototype to pilot- and large-scale U.S. manufacturing. The project targets small businesses that have demonstrated proof-of-concept devices or processes in the laboratory. Their success supports U.S. Secretary of Energy Steven Chu's SunShot Initiative, which seeks to achieve PV technologies that are cost-competitive without subsidies at large scale with fossil-based energy sources by the end of this decade. The Incubator Project has enhanced U.S. PV manufacturing capacity and created more than 1200 clean energy jobs, resulting in an increase in American economic competitiveness. The investment raised to date by these PV Incubator companies as a result of DOE's $ 59 million investment totals nearly $ 1.3 billion.

    A return to the Moon to extend human presence, pursue scientific activities, use the Moon to prepare for future human missions to Mars, and expand Earth?s economic sphere, will require investment in developing new technologies and capabilities to achieve affordable and sustainable human exploration. From the operational experience gained and lessons learned during the Apollo missions, conducting long-term operations in the lunar environment will be a particular challenge, given the difficulties presented by the unique physical properties and other characteristics of lunar regolith, including dust. The Apollo missions and other lunar explorations have identified significant lunar dust-related problems that will challenge future mission success. Comprised of regolith particles ranging in size from tens of nanometers to microns, lunar dust is a manifestation of the complex interaction of the lunar soil with multiple mechanical, electrical, and gravitational effects. The environmental and anthropogenic factors effecting the perturbation, transport, and deposition of lunar dust must be studied in order to mitigate it?s potentially harmful effects on exploration systems and human explorers. The Dust Management Project (DMP) is tasked with the evaluation of lunar dust effects, assessment of the resulting risks, and development of mitigation and management strategies and technologies related to Exploration Systems architectures. To this end, the DMP supports the overall goal of the Exploration Technology Development Program (ETDP) of addressing the relevant high priority technology needs of multiple elements within the Constellation Program (CxP) and sister ETDP projects. Project scope, plans, and accomplishments will be presented.

    Dynamic interceptive actions, such as catching or hitting a ball, are important task vehicles for investigating the complex relationship between cognition, perception, and action in performance environments. Representative experimental designs have become more important recently, highlighting the need for research methods to ensure that the coupling of information and movement is faithfully maintained. However, retaining representative design while ensuring systematic control of experimental variables is challenging, due to the traditional tendency to employ methods that typically involve use of reductionist motor responses such as buttonpressing or micromovements. Here, we outline the methodology behind a custom-built, integrated ball projection technology that allows images of advanced visual information to be synchronized with ball projection. This integrated technology supports the controlled presentation of visual information to participants while they perform dynamic interceptive actions. We discuss theoretical ideas behind the integration of hardware and software, along with practical issues resolved in technological design, and emphasize how the system can be integrated with emerging developments such as mixed reality environments. We conclude by considering future developments and applications of the integrated projection technology for research in human movement behaviors.
