    Berkov, D. V.; Gorn, N. L.

    2002-04-01

    We demonstrate that the Ito and the Stratonovich stochastic calculus lead to identical results when applied to the stochastic dynamics study of magnetic systems consisting of dipoles with the constant magnitude, despite the multiplicative noise appearing in the corresponding Langevin equations. The immediate consequence of this statement is that any numerical method used for the solution of these equations will lead to the physically correct results.

    Both crystallization and molecular density are significant to achieve high electrical conductivity of transparent electrodes. Herein, we investigated the embedding effects of indium tin oxide (ITO) nanoparticles (NPs) into ITO nanofibers (NFs) synthesized by utilizing an electrospinning technique from ITO precursor solutions. We found that the ITO NPs might act as nucleation seeds that initiate crystallization of ITO, evidenced by flake-like morphologies which cannot be observed without ITO NPs. XRD measurements reveal that the ITO is crystalline with a higher degree and the size of ITO crystallites increases in the presence of ITO NPs embedded into NFs. Embedding ITO NPs leads to the formation of short fibers, but there is still large space between fibers as they are vertically stacked in the films, resulting in low electrical conductivity. Interestingly, a high ratio of ITO NPs enhances the electrical conductivity, as compared to a low ratio, which we attribute to the high fiber density on substrates due to the formation of shorter ITO NFs. Our results highlight that the ITO NPs influence not only the ITO crystallization but also the lengths of NFs. High electrical conductivity of NF films can be obtained by a high degree of crystallization and the optimum NF length that reduces spaces between NFs in the films.

  8. Imaging the Rural: Modernity and Agrarianism in Hiroshi Hamaya’s ‘Snow Land’ Photographs

    Directory of Open Access Journals (Sweden)

    Ross Tunney

    2015-06-01

    Full Text Available This article analyses the Snow Land photographic series by Japanese photographer Hiroshi Hamaya [1915–1999] in relation to issues of modernity, nostalgia and discourses of agrarianism in 1940s and 1950s Japan. Hamaya is one of Japan’s most celebrated and influential documentary photographers at both a national and international level. His Snow Land series presents an idyllic view of life in the small mountain villages of Japan’s Niigata Prefecture, emphasising a sense of community and spiritual meaning that Hamaya perceived to be lacking in modern society. In this sense, Snow Land constituted a critique of modernity. Through engagement with theorists such as Heidegger, Foucault and Barthes, as well as critical writings on agrarian ideology, this article investigates the underlying assumptions that govern Hamaya’s depiction of snow country, demonstrating that the series is shaped by a modern worldview and is tied to ideological discourses of agrarianism.

    Full Text Available CORPUS studies have increasingly been of interest to music theorists, musicologists, and music psychology researchers, as is evident in the sheer number of excellent submissions to this special issue. The breadth and depth of these articles, as well as the insightful commentaries, make it seem only fitting to publish over two issues. The current issue contains five articles, eight commentaries, and one research report, and covers folk music, post-tonal music, jazz, Western art music, and the popular music found on Youtube. Eerola presents a model of melodic entropy that provides a nice framework for future information-theoretic work, while Roger Dean and Marcus Pearce present a new approach to modelling pitch-structure in post-tonal music. Frieler, Pfleiderer, Abeßer, and Zaddach give an analysis of jazz solos that demonstrates the role of a narrative arcs in improvisation. White and Quinn present a new corpus that makes use of vast compilations of web-based MIDI data, and demonstrates how such a corpus might be facilitate future musicological and music-theoretic research. Plazak focuses on Youtube as a corpus, and argues that the mutability of such a corpus facilitates our understanding of musical communication, as well as the important role of the listener in defining and re-defining such a dataset. It's encouraging to me both as an editor and practitioner of corpus methods that so many of those heavily involved with the field contributed to these two issues as either an author or a commentator. This issue also brings a number of changes on other fronts. Firstly, Nicola Dibben and Renee Timmers, who served as the journal's editors since Volume 7, have completed their editorial terms. They oversaw the transformation of the journal into a new Open Journal Systems platform, and were able to consistently produce issues that set a very high standard. Under their leadership, the journal both increased its accessibility (we now average more than 1

    Full Text Available Roger M PinderEditor-In-Chief, Neuropsychiatric Disease and TreatmentSchizophrenia remains one of the most debilitating and intractable illnesses in psychiatry. Despite the availability of effective drug treatment since the beginning of the psychopharmacological era in the early 1960s with the introduction of the first antipsychotic chlorpromazine, the subsequent development of second generation or atypical antipsychotics, and the effectiveness of certain types of psychotherapy, many patients are unresponsive and remain unwell for several years or relapse after apparent response. Only clozapine has proven efficacy in treatment-resistant schizophrenia, but many patients still do not respond. Polypharmacy is common, with many physicians choosing to augment rather than switch medications. Schizophrenia may be in part a neurodevelopmental disorder and involve changes in brain structure, and credence has been given to the idea that the prodromal phase, before overt symptoms have appeared, should already have been addressed with aggressive treatment. Various aspects of schizophrenia and its treatment, as well as the associated use of antipsychotic drugs in the treatment of the manic phase of bipolar disorder and Tourette syndrome, have been covered in the pages of Neuropsychiatric Disease and Treatment during the first half of 2012.

Reviews Last year I announced a revival of Nuclear Fusion Reviews, following a decision by the Board of Editors. 'A review of zonal flow experiments', by Akihide Fujisawa was the first fruit of this. In 2010, we are expecting to publish further review articles, the first of which is entitled 'Gyrokinetic simulations of turbulent transport' by Xavier Garbet, Yasuhiro Idomura, Laurent Villard and Tomo-Hiko Watanabe. Letters At the 2009 Board of Editors Meeting in Atlanta, the current letters procedure was summarized and it was noted that the peer review time for Letters is quite variable. Some are accepted within a month of submission, others take longer. Since the purpose of Letters is to provide a route for rapid communication, this is quite an important matter. It was agreed that the Board of Editors would play a more active role in the Letter approval process. If a reviewer asks for a second revision the Editor or a Board of Editors member will be queried as to whether the submission should still be treated as a Letter rather than a regular Paper. The Board of Editors The following Board of Editors members reached the end of their term in 2009: Amanda Hubbard, Yaroslav Kolesnichenko, Kunioki Mima, Boris Sharkov and Michael Ulrickson. On behalf of the Nuclear Fusion Office and the Chairman of the Board of Editors, Mitsuru Kikuchi, I would like to thank them for their efforts in support of the journal. At the same time, we welcomed: Hiroshi Azechi, Xuru Duan, Richard Hawryluk, Sergey Konovalov, Bruce Lipschultz, Peter Norreys, Francesco Romanelli, Tony Taylor and Hartmut Zohm. I am sure that such an illustrious group does not need any introduction to the readers of Nuclear Fusion and I am confident that the new members can only further the success of the journal.

Because universities are slow to change due to maintaining a balance of tradition and change successful implementation of change will continue to be a challenge both now and in the future. The challenge of change is real but the task is not impossible. Historically, universities have met the challenges that faced them, they must be prepared to confront this challenge too.

Their paper provides an overview in general education, in particular foreign language education, can be acknowledged as a lifelong learning process which can be transformed beyond the borders in global sense. Learning a foreign language requires proficiency in four basic skills which are reading, writing, speaking, and listening. Of these skills, speaking and listening are the most daunting tasks for learners and create obstacles when learners of target language do not get the chance of meeting native speakers. Such obstacles can be overwhelmed by integrating certain applications into education process. Service-learning through the internet as a teaching method can be considered one of the most striking one of those applications for foreign language learners. Paper focuses on the benefits of service-learning are discussed and some suggestions are offered for introducing this method in foreign language settings. The second notes for editor is titled as Students’ Opinions On Blended Learning which is written by Meric BALCI and Haluk SORAN from Hacettepe University, Education Faculty, Ankara,Turkey. They mentioned that E-learning was acknowledged by most educators and researchers as a savior, even an only alternative in education field, especially in

Article is entitled as “Globalization, Distance Education And Hegemonic Futures” and written by Dr. Glenn RUSSELL. He says in his paper that “Available options for distance educators can be understood in terms of instrumental and interpersonal axes that can potentially indicate the relative consideration that can be given to these factors. This approach is suggested as one way to understand available options at a time when there has been an apparent increase in instrumental approaches to distance education at the expense of interpersonal approaches and issues of social justice. While this problem is of concern, it is more appropriate to reflect on the unintended consequences of distance education for society and identify them than it is to uncritically oppose globalisation

    Transparent and conducting ITO/Au/ITO multilayered films were deposited without intentional substrate heating on polycarbonate (PC) substrate using a magnetron sputtering process. The thickness of ITO, Au and ITO metal films in the multilayered structure was constant at 50, 10 and 40 nm, respectively. Although the substrate temperature was kept constant at 70 deg. C, ITO/Au/ITO films were polycrystalline with an (1 1 0) X-ray diffraction peak, while single ITO films were amorphous. Surface roughness analysis indicated ITO films had a higher average roughness of 1.76 nm, than the ITO/Au/ITO film roughness of 0.51 nm. The optoelectrical properties of the ITO/Au/ITO films were dependent on the Au thin film, which affected the ITO film crystallinity. ITO/Au/ITO films on PC substrates were developed with a resistivity as low as 5.6 x 10{sup -5} {omega} cm and a high optical transmittance of 71.7%.

    Incorporation of nanomaterials with controlled molecular architecture shows great promise in improving electronic communication between biomolecules and the electrode substrate. In electrochemical applications metal nanoparticles (NPs) modified electrodes have been widely used and are emerging as candidates to develop highly sensitive electrochemical sensors. There has been a growing technological interest in modified indium tin oxide (ITO) electrodes due to their prominent optoelectronic properties and their wide use as a transducing platform. The introduction of NPs into the transducing platform is commonly achieved by their adsorption onto conventional electrode surfaces in various forms, including that of a composite. The aim of this review is to discuss the role of metallic NPs for surface fabrication of ITO thin films leading to detection of specific biomolecules and applications as a biosensor platform.

    Indium tin oxide (ITO) is the material-of-choice for transparent conductors in any optoelectronic application. However, scarce resources of indium and high market demand of ITO have created large price fluctuations and future supply concerns. In polymer solar cells (PSCs), ITO is the single......-cost alternatives to ITO suitable for use in PSCs. These alternatives belong to four material groups: polymers; metal and polymer composites; metal nanowires and ultra-thin metal films; and carbon nanotubes and graphene. We further present the progress of employing these alternatives in PSCs and identify future...

    2015-10-01

    Full Text Available The characteristics of transparent ITO/Ag-Pd-Cu (APC/ITO multilayer cathodes were investigated for use in inverted organic solar cells (IOSCs. The insertion of an APC interlayer into the ITO film effectively led to crystallization of the top ITO layer, unlike that in the Ag interlayer, and resulted in a low sheet resistance of 6.55 Ohm/square and a high optical transmittance of 84.14% without post annealing. In addition, the alloying of the Pd and Cu elements into Ag prevented agglomeration and oxidization of the metal interlayer and led to more stable ITO/APC/ITO films under ambient conditions. The microstructure and interfacial structure of the transparent ITO/APC/ITO cathode in the IOSCs were examined in detail by synchrotron X-ray scattering and high resolution transmission electron microscopy. Furthermore, we suggested a possible mechanism to explain the lower PCE of the IOSCs with an ITO/APC/ITO cathode than that of a reference IOSC with a crystalline ITO cathode using the external quantum efficiency of the IOSCs.

    ITO single-layer and ITO/Ni/ITO (INI) multilayer films were deposited by reactive magnetron sputtering on unheated polycarbonate (PC) substrates. The influence of the Ni interlayer on the structural and optoelectrical properties of the film composite was investigated by keeping the thickness of ITO and INI films at 100 and 50/5/45 nm, respectively. Deposited ITO and INI films had an optical transmittance at a wavelength of 550 nm of 84% and 73% by discounting the PC substrate, respectively, while INI films exhibited a resistivity 10 times lower than that of ITO films (3.2 x 10{sup -4} {omega} cm vs. 3.0 x 10{sup -3} {omega} cm, respectively). XRD diffraction patterns demonstrated that the deposited ITO films had In{sub 2}O{sub 3} diffraction peaks at (1 0 0) and (2 2 2). In contrast, INI films did not have any diffraction peaks. Surface morphology also appeared to influence the Ni interlayer. Specifically, INI films exhibited a lower root mean square (RMS) roughness of 0.5 nm compared with ITO films, which had RMS roughness of 2.1 nm. The figure of merit reached a maximum of 1.3 x 10{sup -3} {omega}{sup -1} for INI films which is greater than that of ITO films (0.5 x 10{sup -3} {omega}{sup -1})

    Transparent conducting indium tin oxide/Au/indium tin oxide (ITO) multilayered films were deposited on unheated polycarbonate substrates by magnetron sputtering. The thickness of the Au intermediated film varied from 5 to 20 nm. Changes in the microstructure, surface roughness and optoelectrical properties of the ITO/Au/ITO films were investigated with respect to the thickness of the Au intermediated layer. X-ray diffraction measurements of ITO single layer films did not show characteristic diffraction peaks, while ITO/Au/ITO films showed an In{sub 2}O{sub 3} (2 2 2) characteristic diffraction peak. The optoelectrical properties of the films were also dependent on the presence and thickness of the Au thin film. The ITO 50 nm/Au 10 nm/ITO 40 nm films had a sheet resistance of 5.6 {Omega}/{open_square} and an average optical transmittance of 72% in the visible wavelength range of 400-700 nm. Consequently, the crystallinity, which affects the optoelectrical properties of ITO films, can be enhanced with Au intermediated films.

    Tuning the localized surface plasmon resonance (LSPR) in doped semiconductor nanoparticles (NPs), which represents an important characteristic in LSPR sensor applications, still remains a challenge. Here, indium tin oxide/indium tin alloy (ITO/In-Sn) bilayer films were deposited by electron beam evaporation and the properties, such as the LSPR and surface morphology, were investigated by UV–VIS–NIR double beam spectrophotometer and atomic force microscopy (AFM), respectively. By simply engineering the thickness of ITO/In-Sn NPs without any microstructure fabrications, the LSPR wavelength of ITO NPs can be tuned by a large amount from 858 to 1758 nm. AFM images show that the strong LSPR of ITO NPs is closely related to the enhanced coupling between ITO and In-Sn NPs. Blue shifts of ITO LSPR from 1256 to 1104 nm are also observed in the as-annealed samples due to the higher free carrier concentration. Meanwhile, we also demonstrated that the ITO LSPR in ITO/In-Sn NPs structures has good sensitivity to the surrounding media and stability after 30 d exposure in air, enabling its application prospects in many biosensing devices.

    It has been nearly a year since Ronald Cummings took over as policy sciences editor of Water Resources Research (WRR), and in that time he has worked to make the journal live up to its role as “an interdisciplinary journal integrating research in the social and natural sciences of water.” Cummings takes the “interdisciplinary” part seriously. “I'd like to see a much broader range of policy issues presented to readers,” he says. “I would hope it would then stimulate interchange between our colleagues concerning evolving issues of the '80s and '90s.”Cummings brings a solid background as a resource economist to his 4-year term as editor, which began last January and runs until December 1987. Cummings succeeds Jared Cohon as policy sciences editor. Stephen J. Burges is the WRR editor for hydrological, physical, chemical, and biological sciences. Now a Professor of Economics and Director of the Program in Natural Resources Economics at the University of New Mexico, Cummings is a past president of the Association of Environmental and Resource Economists. He has been a consultant in matters of water resources management, forestry management, and energy policy for more than a decade, working on projects in both the United States and Latin America. Since joining the faculty at New Mexico in 1975, he has, among other things, worked with engineers at the Los Alamos National Laboratory in developing operation'management models for hot, dry rock geothermal systems.

    Full Text Available El intelectual abre ideas, el editor las cierra. El escritor produce textos, el editor impresos. El intelectualescribe pero es el editor quien publica. No por nada, afirman algunos psicólogos, el pensamientoculmina con su publicación. Entre el escritor y el editor se moviliza una energía simbólica y socialsublimada bajo las líneas impresas que llegan al lector. Ese entre-lugar de producción de sentidos, decosmologías, de sociedad que marcó la formación de gran parte de las culturas desde la aparición de laexpresión gráfica de las ideas, permanece como un problema esquivo para la investigación, al menospara la antropología practicada en estas latitudes. Parece una cuestión obturada por el dominanteacúmulo de historias de las ideas, de la literatura, del pensamiento que reactualizan la oposición entreespíritu y materia, estética y sociedad, texto y contexto. Evidencia de ello es la clausura sufrida por lasociología de la literatura, una sub-disciplina tan incómoda para los guardianes del aura del genioliterario nacional.Este dossier busca iluminar esa relación con la certeza de que modela uno de los terrenos másfértiles para repensar el legado de la historia de la cultura en occidente y para generar un basto programade problemas de investigación escasamente explorados por las ciencias sociales y humanas en AméricaLatina, y aplicables al estudio de toda cultura, con o sin escritura.

    In this paper, a ITO algorithm inspired by ITO stochastic process is proposed for Traveling Salesmen Problems (TSP), so far, many meta-heuristic methods have been successfully applied to TSP, however, as a member of them, ITO needs further demonstration for TSP. So starting from designing the key operators, which include the move operator, wave operator, etc, the method based on ITO for TSP is presented, and moreover, the ITO algorithm performance under different parameter sets and the maintenance of population diversity information are also studied.

    Directory of Open Access Journals (Sweden)

    Ningyu Ren

    2017-05-01

    Full Text Available ITO/Ag/ITO (IAI trilayer films were deposited on glass substrate by radio frequency magnetron sputtering at room temperature. A high optical transmittance over 94.25% at the wavelength of 550 nm and an average transmittance over the visual region of 88.04% were achieved. The calculated value of figure of merit (FOM reaches 80.9 10-3 Ω-1 for IAI films with 15-nm-thick Ag interlayer. From the morphology and structural characterization, IAI films could show an excellent correlated electric and optical performance if Ag grains interconnect with each other on the bottom ITO layer. These results indicate that IAI trilayer films, which also exhibit low surface roughness, will be well used in optoelectronic devices.

The title of the first report is “Roma Health in Edirne: Social Determinants of Health and Health Status”. In their report, Eskiocak et al. investigate the social determinants of health and their health related outcomes among the Roma communities living in Edirne. The second report deals with gender related issues. Doğan et al. investigate the effects of gender inequality on women's lives through a comparison of countries that do and do not implement policies based on gender equality.Original articles in this issue cover many important public health issues. The first, conducted by Koçak et al., investigates the type 2 diabetes risk of primary school teachers and their lifestyle behaviors. Results of the study show that 5.7% out of 975 primary school teachers have a high risk of type 2 diabetes.The second original article entitled “Unintended pregnancies, induced abortions and risk factors in women admitted to hospitals due to birth or abortion in Hatay” was based on a study of 635 women. The results of this study, done by Savaş et al., show an unintended pregnancy rate of 15%. It is further estimated that almost half of all induced abortions are reported as spontaneous abortions. The third article, which was written by Çam et al., is about the frequency of eating disorders in adolescents. This descriptive study, with the participation of 338 high school students, found the frequency of eating disorder attitudes to be 18.3% among the participants. In a descriptive study conducted by Emerce et al., the knowledge and practice of laboratory safety by laboratory analysts and technicians was investigated.

    Full Text Available Teaching about globalizations and our interconnectedness with people and places around the world is an essential component of K-12 and higher education, but knowledge about global issues and news is not enough. Increased mobility, digital communication, and cultural hybridity, along with oppression and social injustice require that educators and students not only be able to communicate and collaborate with people different from them, but regularly engage in critical self-reflection around perceived norms and values. In January 2016, the editors of this special issue distributed a call for theoretical, research-based, and practitioner oriented manuscripts on teaching and learning that bring social studies and global citizenship education together. Evidence by the transnational contributions published within this issue of the Journal of Social Studies Education Research, the place of global citizenship education within the social studies is evolving, multifaceted, and not without complications.

    Since its first issue in 1965 Metrologia has had just three editors, a history of tenure which suggests that those who hold the post find in it sufficient to interest, occupy, challenge and amuse them. I see no reason to doubt that this happy circumstance will continue and look forward to my own period as editor with the intention of retaining, insofar as I am able to interpret them, the best traditions the journal has established so far. As I take up my editorial duties I have become aware that surrounding Metrologia there is a small community of authors, reviewers and readers on whose support the success of the journal entirely depends. It is a community in which the roles change daily with some of its members engaged, even simultaneously, as reader, reviewer and author. I am well aware that the goodwill extended to me as I enter this community is in no small part due the efforts of the outgoing editor, Dr Ralph Hudson, whose easy, engaging and courteous, yet firm, relationship with authors and reviewers emerges clearly from editorial correspondence. I thank him for that he has done and wish him an active and happy retirement. A short foray into the records of Metrologia shows - in the first editorial - that four main kinds of article were originally envisaged: research articles likely to contribute to progress in fundamental scientific measurements, reports of experiments or techniques of particular importance or originality in the area of secondary measurement, articles concerning the decisions of the Comité International des Poids et Mesures, and review articles. No balance was specified but a priority was assigned to articles dealing with fundamental metrology. Of the four categories, the first two represent the core of Metrologia's activity and largely determine its reputation as a publication. For this reason, editorial implementation of the policy set by the CIPM is mainly exercised through the operation of a reviewing system which is intentionally strict

    In this study, ITO nanoparticles (ITO-NPs) were reused from ITO target scraps to synthesize low cost ITO-NPs and to apply to make sputtering target for transparent conductive electrodes (TCEs). By controlling heat-treatment temperature as 980 °C, we achieved reused ITO-NPs having Brunauer, Emmett and Teller specific surface area (BET SSA) and average particle size 8.05 m2/g and 103.8 nm, respectively. The BET SSA decreases along with increasing heat-treatment temperature. The ITO-NPs were grown as round mound shape, and highly crystallized to (222) preferred orientations. Also, applying the reused ITO-NPs, we achieved an ITO target of which density was 99.6%. Using the ITO target, we achieved high quality TCE layer of which sheet resistance and optical transmittance at 550 nm were 29.5 Ω/sq. and 82.3%. Thus, it was confirmed that the reused ITO-NPs was feasible to sputtering target for TCEs layer.

Of particular interest is reported experience with a dynamic QoS adaptation protocol implemented in the network and based on video scaling techniques and filtering. In summary, this special issue provides an up to date review of approaches to QoS management and their practical realization. Of course, no claim is made as to comprehensiveness, but the chosen papers do serve as a highly representative sample of current directions in QoS research. The editors are very much obliged to all authors, reviewers and publishers. Without their excellent work, and the contribution of their valuable time this special issue would not have been possible.

Microstructures, surface morphology, crystallite size of the nanoparticles were studied using X-ray diffractometer (XRD), field emission scanning electron microscope (FE-SEM). From these methods it was found that the particles were about 45 nm. Chemical composition and valence states of the nanoparticles were studied using energy dispersive analysis of X-rays (EDAX) and X-ray photoelectron spectroscopy (XPS). From these techniques it was observed that the elements of indium, tin, chromium and oxygen were present in the system in appropriate ratios and they were in +3, +4, +3 and −2 oxidation states. Raman studies confirmed that the nanoparticle were free from unintentional impurities. Two broad emission peaks were observed at 330 nm and 460 nm when excited wavelength of 300 nm. Magnetic studies were carried out at 300 K and 100 K using vibrating sample magnetometer (VSM) and found that the ITO nanoparticles were ferromagnetic at 100 K and 300 K. Where-as the room temperature ferromagnetism completely disappeared in Cr doped ITO nanoparticles at 100 K and 300 K.

    It is hard to believe but Clinical and Investigative Medicine (CIM), the official journal of Canadian Society for Clinical Investigation (CSCI), will soon celebrate its 40th birthday!  Over these past four decades, CIM has been the premier journal for Canadian clinician scientists; publishing over 1,000 articles on breakthroughs and major advances from Canada and around the world.  We are listed on Medline, PubMed and the Library of Science. We have been, and will continue to be, an independent journal. To celebrate this auspicious occasion, we have plans to become an even bigger showpiece for national and international clinical advances. We want to connect more closely with Canadian clinician scientists and trainees and we particularly want to encourage more Canadian publications. Changes will soon be coming to CIM with several new features: Newsletter with announcements and news on activities of interest to clinician scientists and trainees; Focused Reviews on specific areas of research; Reflections on work and life experiences of trainees and senior clinician scientists; Methods Papers describing novel methods anticipated to be useful for others; and  Guidelines or Recommendations on clinical care that are endorsed by a Canadian Medical or Surgical Society. Starting in 2018, we will be publishing on a quarterly basis. This will help to ensure we will focus on important breakthroughs and commentaries. However, we are also planning a special edition in the autumn to commemorate the 40th birthday. Stay tuned! Of course CIM will continue to publish original papers on discoveries in pathophysiology, prevention, management, treatment and outcome of clinical problems confronting clinicians in Canada and around the world.  Please join us as we embark on these changes and a new era for CIM, Robert Bortolussi Clinical and Investigative Medicine (CIM) Editor in Chief.

Whereas, on one hand, this problem presents a formidablechallenge to any scientist dealing with it, its solution, especially in case it should turn out tobe a positive one considering that current technology tends to evolve in a practicaldirection and its overall functioning is conducted implicitly under the assumption of anegative solution would have a major impact on the development of informationtechnology as well as the wider context of human society as a whole.

    The electroactivity of nanostructured indium tin oxide (ITO) has been investigated for its further use in applications such as sensing biological compounds by the analysis of redox active molecules. ITO films were fabricated by using electron beam evaporation at different substrate temperatures and subsequently annealed for promoting their crystallization. The morphology of the deposited material was monitored by scanning electron microscopy, confirming the deposition of either thin films or nanowires, depending on the substrate temperature. Electrochemical surface characterization revealed a 45 % increase in the electroactive surface area of nanostructured ITO with respect to thin films, one third lower than the geometrical surface area variation determined by atomic force microscopy. ITO surfaces were functionalized with a model organic molecule known as 6-(ferrocenyl)hexanethiol. The chemical attachment was done by means of a glycidoxy compound containing a reactive epoxy group, the so-called 3-glycidoxypropyltrimethoxy-silane. ITO functionalization was useful for determining the benefits of nanostructuration on the surface coverage of active molecules. Compared to ITO thin films, an increase in the total peak height of 140 % was observed for as-deposited nanostructured electrodes, whereas the same measurement for annealed electrodes resulted in an increase of more than 400 %. These preliminary results demonstrate the ability of nanostructured ITO to increase the surface-to-volume ratio, conductivity and surface area functionalization, features that highly benefit the performance of biosensors.

    ısı” (Social Studies Teachers’ Perceptions of Tolerance and Feryal Çubukçu “Values Education Through Literary Texts”. These valuable papers have potential to contribute the literature on social studies education. One of the main aims of ASSE was to establish a regular scientific event through which social studies educators from Turkey and abroad get together to share their academic works and ideas. In conjunction with the Faculty of Education of Bolu Abant Izzet Baysal University we are organizing the Fourth International Symposium on Social Studies Education (ISSE in April 2015. The main theme of ISSE the 4th is “Peace Education”. The preference of this theme emphasizes on our hopes and determination for our envision for peace in the late Ottoman geography, in which guns have still been on fire and people have still been shedding tears. And this could be regarded as something similar to the action of Mustafa Kemal Pasha who thought of about the reconstruction of the country after the war and assembled an “Educational Congress” in Ankara to discuss educational issues, during the most difficult days of the War of Independence in 1921. Adopting this approach, we have been considering putting effort to institutionalize the values of democracy, human rights, justice, freedom of thought and freedom of conscience. As a final remark, I would like to thank everyone who contributed to the production of this issue and special thanks to Assoc. Prof. Dr. Erkan Dinç who acted as issue editor. Best regards and hope to meet you in ISSE the 4th…

D. (chief and executive editor of the journal Thermal Science and professor Milan Radovanović, Ph. D. (president of the Society of Thermal Engineers of Serbia. Gratitude that we have is not only for their effort as researchers and creative and challenging education, but also for the founding and guidance of Thermal Science, today internationally known and appreciated science journal. This long term editing work that professor Oka and professor Radovanović nurse within the Society of Thermal Engineers of Serbia became window to world for Serbian researchers. Publishing the scientific article in the journal Thermal Science today is not only the major research event for domestic scientists but for the researchers all over the world. About excellent science and nurture characters of professor Oka and professor Radovanović is saying a lot the decision to dedicate this special issue of the journal Thermal Science to fifty anniversary of Faculty of Mechanical Engineering in Kragujevac. This decision was greeted by the employees of MFKG as a special and dear acknowledgment for their effort during fifty years long research work.

In their notes they mentioned that Students register the device on the company Web site, and the instructor synchronizes the database in order to know which students have registered devices, thus creating accountability for “quizzes” in class. During the lecture, students “vote” for multiple choice answers on screen, and real-time results are displayed (anonymously after the polling is finished, providing instant formative feedback. Another model is for a department or institution to purchase clickers and make available in the classroom. Students pick up the clicker as they enter the room each day and replace when exiting. Using this approach does not allow for direct accountability, unless students are registered to a specific number on the clicker, which is documented and tracked.

    The purpose of this experiment was to determine the modulus of elasticity (E) and thermal expansion coefficient (α) of RF sputtered Indium Tin Oxide (ITO) as a function of temperature (T), and to collect ITO film stress data. In order to accomplish that goal, the Toho FLX-2320-S thin film stress measurement machine was used to collect both single stress and stress-temperature data for ITO coated fused silica and sapphire substrates. The stress measurement function of the FLX-2320-S cannot be used to calculate the elastic modulus of the film because the Stoney formula incorporates the elastic modulus of the substrate, rather than of the film itself.

    We demonstrate a facile approach to designing transparent electron-collecting electrodes by depositing thin layers of medium and low work function metals on top of transparent conductive metal oxides (TCOs) such as ITO and FTO. The modified electrodes were fairly stable for months under ambient conditions and maintained their electrical characteristics. XPS spectroscopy data strongly suggested integration of the deposited metal in the TCO structure resulting in additional doping of the conducting oxide at the interface. Kelvin probe microscopy measurements revealed a significant decrease in the ITO work function after modification. Organic solar cells based on three different conjugated polymers have demonstrated state of the art performances in inverted device geometry using Mg- or Yb-modified ITO as electron collecting electrode. The simplicity of the proposed approach and the excellent ambient stability of the modified ITO electrodes allows one to expect their wide utilization in research laboratories and electronic industry.

The x-ray photoelectron spectroscopy was used to obtain the chemical nature from the NWs surface, investigating the oxygen vacancy state. A stable switching voltages and a clear memory window were observed in needle-shaped NWs. The ITO-NW networks can be used as a new two-dimensional metal oxide material for the fabrication of high-density memory devices.

    the role of universities as content producers for credentialed learning to be questioned, prompting many educators to explore new ways of supporting online learning. The sixth article from Palitha Edirisingha (UK, Chiara Rizzi (Italy, Ming Nie (UK and Libby Rothwell (UK report on a study involving the use of podcasting (Curry, 2004 to provide teaching and learning support for an undergraduate module on English Language and Communication. The findings led to development of a model for integrating podcasts in on-campus blended learning, and which can have potential applications in distance learning contexts. The model is based on three main features of podcasts identified as facilitating student learning: learner choice and flexibility offered by podcasts; tacit knowledge and experience of peers conveyed in discussions; and a sense of informality brought into formal learning. Also from the implementation perspective, Penny de Byl and Janet Taylor (Australia describe a Web 2.0/Web3D hybrid e-learning platform, called the AliveX3D platform, which involves the application of the Web 2.0 ethos to an online 3D virtual environment. The platform and accompanying tools are designed to enable the creation of authentic learning experiences with a large degree of learner control, and to promote collaborative dialogue between learners. The immersion in the 3D worlds enables learners to negotiate meaning based on their own personal cognitive, affective and kinaesthetic experiences rather than relying merely on descriptions of others’ experiences. Last but not least, the “Notes to the Editor” section contains a contribution from Yavuz Akbulut and Mübin Kiyici (Turkey, on the instructional uses of blogs. And two book reviews from the field. We hope you enjoy reading this contributions, and welcome your feedback, rejoinders and reflections on the various articles contained within this special issue. Mark J. W. LEE and Hakan G.

    Full Text Available Greetings Dear readers of TOJDE,TOJDE is appeared on your screen now as Volume 13 Number: 1 In this issue it is published 5 notes for Editor, 16articles, 2 books reviews a nd this time, 53 authors from 12 different countries are placed. These published articles are from Azerbaijan, Bangladesh, Greece, Iran, Malaysia, Morocco, Nigeria, Pakistan, Turkey, UAE and USA.The first Notes for editor arrived from USA, written by Kevin YEE and Jace HARGIS. They focused on Simply including a narrative component may provide enough creative ammunition for students to feel that a particular assignment can be more interesting (Clark 2010, if their work is to be wrapped around a narrative format, such as a short story in favor of an essay or formal writing. But there are numerous free technology tools available today that take the process one step further, by injecting different editing options and high-end production values. Students do not merely assemble a story in words. They can now do it primarily with images, and many of the slideshow services online allow for text captions, dynamic transitions, special effects, and relevant animations. Students become videographers and directors as much as they function as storytellers. The slideshow builders thus do a better job than “old fashioned” essay/short story assignments at meeting the need of 21st century students, many of whom arrive at institutions of higher learning with at least an already-ingrained interest in such tools, if not explicit experience.The following note is that a review of existing literature pertaining to servant leadership and faculty development. Specifically, this work discussed delivering servant leadership to online faculty through the utilization of a faculty development program. The idea for this literature review stemmed from the author asking how an online academic administrator could utilize the practice of servant leadership in order to improve the overall online academic

Therefore, more research on gender, attitude, and experience in such programs is needed to understand how students work with mathematical software programs and use them as learning tool in the class environment. Next article is from Bangladesh Open University, BANGALDESH, which written by Md. Tofazzal ISLAM from School of Agriculture and Rural Development, Morshedur RAHMAN and K. M. Rezanur RAHMAN from School of Science and Technology, Bangladesh Open University, which is titled as Quality And Processes Of Bangladesh Open University Course Materials Development“. Their paper, attempt to describe the processes and quality of BOU course materials development taking into account the strengths and weaknesses as well as possible ways of improvement. It is mentioned in their article that as a new member of the mega-Universities, Bangladesh Open University (BOU introduced with an example a course team approach for developing effective course materials for distance students. BOU teaching media includes such as printed course books, study guides, radio and television broadcasts, audiocassettes and occasional face-to-face tutorials. Each course team comprises specialist course writer(s, editor, trained style editor, graphic designer, illustrator, audio-visual producer and anonymous referees. An editorial board or preview committee is responsible for the final approval for publishing or broadcasting materials for learners. This approach has been proved to be effective, but appeared to be complicated and time-consuming. This report focuses on the quality and processes of BOU course materials development taking into account the strengths and weaknesses of the current approach.

    Full Text Available Dear TOJDE Readers, Welcome to the Volume 14 Number: 1 of TOJDE! In this issue, 31 articles of 65 authors from 12 different countries around the world have been published. These published articles are arrived to the TOJDE from Australia, Guyana, India, Indonesia, Iran, Malaysia, Nigeria, Russia, Taiwan, Turkey, USA and Zimba bwe. First all, you should know that if a submission picks up from three TOJDE editors between 4.5 and 9 over all 9 credits, it means that this submission can be published in TOJDE in the coming issue. However, since the publishing priority of the accepted papers belongs to the highest scored ones, submissions which receive a score between 4.5 and 5 or 6 may wait and be archived for publishing later on. TOJDE administration respected this publishing rule up to now. Therefore, some accepted submissions which obtained over 4.5 have not been published up to now. Some of these submissions were waiting for publishing in TOJDE in the future sice 2011. In this issue, we decided to give them a chance to be published. For this reason that becoming end of the year of 2012, more papers for this issue included me than the previous issues. The 1st article arrived from Nigeria and written by Sunday O. ADEGBESAN, from Training and Research Fellow, National Institute for Educational Planning and Administration (NIEPA, on “Effect Of Principals’ Leadership Style On Teachers’ Attitude To Work In Ogun State Secondary Schools, Nigeria ". The purpose of this study was to investigate why some principals prefer to embrace certain leadership styles and the effect of such styles on the teachers’ attitude to work. In the 2nd article is mentioned in their context, especially web-based learning comes forward. Web-based learning can be defined as an information technology-enabled and supported form of distance learning in which the traditional restrictions of classroom learning have disappeared. The Internet can be a useful aid in teaching

    The effects of proton damage on transparent conducting indium tin oxide (ITO) layers were investigated by electrical and optical techniques. ITO layers were found to be highly resistant to proton damage for fluences up to 10{sup 16} ions cm{sup -2}. For fluences greater than 10{sup 16} cm{sup -2} the resistivity rises rapidly with a corresponding degradation of the transmittance. ((orig.))

    In this study, we show that discrete Ito equations with short-tail Gaussian marginal distribution function generate multifractal time series. The multifractality is due to the nonlinear correlations, which are hidden in Markov processes and are generated by the interrelation between the drift and the multiplicative stochastic forces in the Ito equation. A link between the range of the generalized Hurst exponents and the mean of the squares of all averaged net forces is suggested.

    , Bogazici University, Istanbul,TURKEY. This paper examines the emerging ideas to implement the usage of Second Life as an educational tool in a wide range of subject areas. The majority of the information used to create these 10 pedagogical approaches was derived from a series of participative inquiries, personal observations, formal and informal interviews, and documenting the perceptions of teachers and students using (and trying to use Second Life as an educational tool. Ten pedagogical approaches have emerged thus far. Each section briefing explains the concept, illustrates the idea with examples, and provides implementation suggestions. The sixth article from USA on “USE OF SECOND LIFE IN K-12 AND HIGHER EDUCATION: A Review of Research”, written by Chris INMAN, Vivian H. WRIGHT & Julia A. HARTMAN, from The University of Alabama, USA. This artile is published in Journal of Interactive Online Learning, Volume 9, Number 1, Spring, 2010 and republished by official permission of JIOL Editor-in-Chief’. This study reviewed empirical research conducted in Second Life by educators since Second Life’s launch in 2003. The study’s purpose was to identify how Second Life is being used in both K-12 and higher education. The methodology, findings, and recommendations of 27 research studies were analyzed. Researchers identified potential problems when using Second Life in education, including issues with the Second Life software and hardware requirements, a steep learning curve, and the possibility of students becoming exposed to distractions or inappropriate content.

Dr. Mehmet KURT from Ankara University, Department of Educational Sciences Program of Curriculum and Instruction TURKEY. This summary is his doctorate thesis which is completed on March 2006 at Ankara University. He emphasizes that while in the teaching process they use both synchronous and asynchronous presentation technologies; in order to support course content they use e-mail, web, cd, and course book technologies to provide basic learning environment function; they prefer different environments to cover face to face education needs; they take self learning and collaboration as basis and they take projects and term paper evaluations serious; they mostly prefer multiple choice tests and they usually make virtual courses exams through the internet. Regarding the characteristics of their institutions’ applications, the study group have agreed on mostly to connection and being dependent on connection opportunities. A significant difference between their institutions’ characteristics and the model for developing computer labs, when they had started to provide virtual lessons and presentation technologies used has been found.The first article of this issue is coming from Hellenic Open University, GREECE which is written by Paraskevi VASSALA.

  4. Incontinentia pigmenti and hypomelanosis of Ito.

    2013-01-01

    Incontinentia pigmenti (IP) is a rare X-linked dominant neurocutaneous disorder affecting ectodermal tissue: skin, eyes, central nervous system, hair, nails, and teeth. It is usually lethal for males in utero. The involved gene is NEMO, an essential component of the nuclear factor-kappa B (NF-κB) signaling pathway. Skin lesions are highly diagnostic, occurring in neonates, with a particular distribution on Blaschko lines. The severity of the disease is related to ocular and neurological impairment. The hallmark of ocular IP is retinal vasculopathy including peripheral retinal vascular nonperfusion, macular infarction and neovascularization, and preretinal neovascularization. CNS involvement consists of seizures, mental retardation, hemiparesis, spasticity, microcephaly, cerebellar ataxia, and coma. It often occurs in neonates. Some patients have persistent pharmacoresistant seizures throughout life. MRI findings consist essentially in: white-matter lesions; scattered cortical neuronal necrosis; multiple cerebral infarctions; cerebral atrophy, hypoplasia of the corpus callosum, encephalomalacia and neuronal heterotopia. A predominant role of vascular occlusive phenomena in small vessels is highly suspected. In fact several intricate mechanisms could be discussed: vascular, inflammatory, developmental mechanisms. Their role and predictive factors of IP CNS involvement in neonatal IP need to be better understood to identify effective innovative therapies. Hypomelanosis of Ito can occur in the neonate, infancy, or childhood, be isolated or diffuse, often following the Blaschko lines, and can fade in childhood or adulthood. It is due to reduced melanin in the epidermis. Eye, central nervous (mental retardation, epilepsy, language disabilities, motor system dysfunction, psychiatric symptoms including autism - with frequent cortical malformations including hemimegalencephaly and white matter involvement), and musculoskeletal systems can also be affected.

    Forming-free bipolar resistive switching behavior in an ITO/V2O5/ITO structure is observed. While the bottom ITO layer functions as a common ground electrode, the top ITO layer is an active element and used as an oxygen reservoir, with an additional metal electrode patterned on its top for making contact. In contrast to typical metal/transition metal oxide/metal based resistive memories, our device exhibits a low resistance state in its virgin state and is switched to a high resistance state when a forward bias of ˜+2.5 V is applied. The device can be reset to its original state at a reverse bias of ˜-1.5 V. A noticeable decrease in switching voltage with a reduced top contact area is observed, indicating a strong electric field enhanced switching mechanism. Different from the widely seen conductive filament mechanism in bipolar switching, we explain the switching behavior by the migration of oxygen ions at the top ITO/V2O5 interface. When oxygen ions are extracted to the ITO side, an interfacial layer with reduced oxidation states is formed and acts as a Schottky barrier that suppresses the current through the whole device. The results suggest future applications in low power, high speed integrated non-volatile memories.

    Research highlights: > We study photoinduced absorption for two Ag NP deposited on the ITO. > The higher resistance eof the NP favors larger photoinduced changes. > Principal role is played by nanointerfaces. - Abstract: Substantial changes of absorption after illumination by 300 mW continuous wave green laser at 532 nm were observed. The effect of indium tin oxide (ITO) substrate was explored versus Ag nanoparticles (AgNPs) size, their regularity and surface plasmon resonance. The ITO substrate features play a crucial role for the formation of homogenous AgNPs. The attachments of AgNPs on ITO surface as well as their homogeneity are significantly changed under the influence of the laser treatment. We study the Ag NP deposited on the two different substrates which play a crucial role in the photoinduced absorption. The dependence of the photoinduced absorption versus the time of optical treatment is explained within a framework of the photopolarization of the particular trapping levels on the borders between the ITO substrate and the Ag NP.

    The valence band offsets in rf-sputtered Indium Tin Oxide (ITO)/single crystal β-Ga2O3 (ITO/Ga2O3) heterostructures were measured with X-Ray Photoelectron Spectroscopy using the Kraut method. The bandgaps of the component materials in the heterostructure were determined by Reflection Electron Energy Loss Spectroscopy as 4.6 eV for Ga2O3 and 3.5 eV for ITO. The valence band offset was determined to be -0.78 ± 0.30 eV, while the conduction band offset was determined to be -0.32 ± 0.13 eV. The ITO/Ga2O3 system has a nested gap (type I) alignment. The use of a thin layer of ITO between a metal and the Ga2O3 is an attractive approach for reducing contact resistance on Ga2O3-based power electronic devices and solar-blind photodetectors.

    Full Text Available Polymer solar cells have shown good prospect for development due to their advantages of low-cost, light-weight, solution processable fabrication, and mechanical flexibility. Their compatibility with the industrial roll-to-roll manufacturing process makes it superior to other kind of solar cells. Normally, indium tin oxide (ITO is adopted as the transparent electrode in polymer solar cells, which combines good conductivity and transparency. However, some intrinsic weaknesses of ITO restrict its large scale applications in the future, including a high fabrication price using high temperature vacuum deposition method, scarcity of indium, brittleness and scaling up of resistance with the increase of area. Some substitutes to ITO have emerged in recent years, which can be used in flexible polymer solar cells. This article provides the review on recent progress using other transparent electrodes, including carbon nanotubes, graphene, metal nanowires and nanogrids, conductive polymer, and some other electrodes. Device stability is also discussed briefly.

    Full Text Available EDITORIALPoblación y Salud en Mesoamérica se complace en entregar a nuestros lectores y público en general el Volumen 7, número 1, correspondiente a julio-diciembre del 2009. En esta oportunidad se disponen 8 artículos divididos en 5 nuevos artículos científicos y 3 artículos en cada una de las secciones de Revisión bibliográfica, Ensayo y de Documentos históricos.La edición recoge dos trabajos elaborados a partir de los datos de la primera Encuesta Nacional de Salud de Costa Rica (ENSA 2006. En el primero, Morera y otros estudian los determinantes de la salud autopercibida en un análisis comparativo entre regiones geográficas, en el que después de controlar por una serie de variables sociodemográficas y socioeconómicas, les permite concluir que existen diferencias significativas a nivel regional para fundamentar una estrategia diferenciada de salud pública. En el segundo, Herring y Bonilla trabajan una submuestra de la ENSA con cerca de 200 inmigrantes de origen nicaragüense, y comparando con el resto de la población costarricense encuestada, utilizando distintos indicadores de salud autopercibida, llegan a concluir que el estado general de salud de los inmigrantes es igual y hasta mejor que la de los locales, producto de una selectividad de la migración, aunque los primeros acusan mayores conductas de riesgo como el fumado y sedentarismo en la actualidad, pero que evidencia que los nicaragüenses no están siendo una sobrecarga en cuanto al uso de los servicios de salud pública en Costa Rica.También a nivel regional pero con diferentes fuentes de información, el artículo de Santamaría aborda el tema de la incidencia del cáncer de mama, entre la población de las áreas de influencia de o exposición al uso de plaguicidas, en un interesante estudio de carácter también ecológico que al combinar análisis estadísticos y espaciales, encuentra una asociación directa y significativa entre la exposición a plaguicidas y los casos de cáncer de mama en mujeres mayores de 45 años residentes en las áreas rurales de los distritos de mayor exposición.Otro artículo ligado al ámbito de la salud reproductiva de la región es el de Remez y otros, quienes analizan datos de las Encuestas de Demografía y Salud (DHS por sus siglas en ingles, para comparar los cambios en la fecundidad adolescente entre los países centroamericanos de menor nivel socioeconómico (Guatemala, Honduras, Nicaragua y El Salvador. Comparando los comportamientos en la nupcialidad y fecundidad de dos cohortes de mujeres separadas por 20 años, encuentran que las uniones consensuales a edades tempranas han disminuido, sin embargo la incidencia en los primeros nacimientos a edad adolescente no muestras claros signos de disminución (excepto en Nicaragua, sobre todo por el efecto de factores como la baja escolaridad y la pobreza, a lo que sugieren reforzar y focalizar las estrategias para ayudar a las jóvenes a utilizar más los anticonceptivos antes y no después del primer nacimiento.El último artículo científico de este número (Cañedo, difiere de los temas anteriores pues aborda el fenómeno de la calidad del empleo entre los profesionales salidos de la Universidad Autónoma de Guerrero, Méjico, mediante un riguroso análisis de ecuaciones estructurales, para así poner a prueba supuestos de las teorías de capital humano, mercados segmentados y capital cultural, y concluye entre otras cosas que dicha calidad en aspectos no formales del capital humano como la experiencia laboral y el desempeño personal, junto al capital cultural familiar, se vuelven más significativos y relevantes que los aspectos formales del capital humano medidos por la formación académica obtenida.En las secciones de Revisión bibliográfica y Ensayo, se presentan dos artículos que abordan un tema de suma actualidad y pertinencia a futuro, como lo es el tema de los modelos de salud pública que tanto los nuevos paradigmas como las condiciones socio históricas actuales, perfilan para el siglo XXI. Por una parte, Chamizo realiza una exhaustiva revisión y análisis bibliográfico para dar cuenta de los modelos de salud pública y saneamiento ambiental en asentamientos humanos, que las comunidades epistémicas y organismos internacionales han hecho prevalecer históricamente en Latinoamérica, tanto en la discusión como en la práctica a partir de modelos sobre la relación Estado-Sociedad, prevaleciendo en la actualidad los denominados modelos neoinstitucionales en sus distintas variantes.

    Full Text Available Transparent ITO/ZnO and ITO/SnO2 complex conductive layers were prepared by DC- and RF-magnetron sputtering. Their structure and optical and electronic performances were studied by XRD, UV/Vis Spectroscopy, and four-probe technology. The interface characteristic and band offset of the ITO/ZnO, ITO/SnO2, and ITO/CdS were investigated by Ultraviolet Photoelectron Spectroscopy (UPS and X-ray Photoelectron Spectroscopy (XPS, and the energy band diagrams have also been determined. The results show that ITO/ZnO and ITO/SnO2 films have good optical and electrical properties. The energy barrier those at the interface of ITO/ZnO and ITO/SnO2 layers are almost 0.4 and 0.44 eV, which are lower than in ITO/CdS heterojunctions (0.9 eV, which is beneficial for the transfer and collection of electrons in CdTe solar cells and reduces the minority carrier recombination at the interface, compared to CdS/ITO. The effects of their use in CdTe solar cells were studied by AMPS-1D software simulation using experiment values obtained from ZnO, ITO, and SnO2. From the simulation, we confirmed the increase of Eff, FF, Voc, and Isc by the introduction of ITO/ZnO and ITO/SnO2 layers in CdTe solar cells.

    There's nothing that hard-core Unix and Linux users are more fanatical about than their text editor. Editors are the subject of adoration and worship, or of scorn and ridicule, depending upon whether the topic of discussion is your editor or someone else's. vi has been the standard editor for close to 30 years. Popular on Unix and Linux, it has a growing following on Windows systems, too. Most experienced system administrators cite vi as their tool of choice. And since 1986, this book has been the guide for vi. However, Unix systems are not what they were 30 years ago, and neither is this

    2001-06-01

    Ito cells are liver-specific pericytes which were first described as Fett Speicherung Zellen, the fat-storing cells encircling outside sinusoidal endothelial cells, in 1951 by the late professor Toshio Ito. His pioneering approaches for morphological characterization of the cells stimulate investigators to further examine their functional roles in liver homeostasis: a body of evidence has been accumulated in recent years showing that the cells play a crucial role in storage and delivery of vitamin A, regulation of sinusoidal tone and local blood supply, and tissue repair and fibrosis. It is now widely accepted that microvascular pericytes including Ito cells serve as a key player that controls angiogenesis. Furthermore, recent studies support a concept that Ito cells constitutes a bridging apparatus mediating bidirectional metabolic interactions between sinusoids and hepatocytes, utilizing prostanoids and/or gaseous mediators such as nitric oxide and carbon monoxide as signaling molecules. This article reviews researches on this liver-specific pericyte and its leading roles in recent development of pericyte biology.

  20. NonMarkov Ito Processes with 1- state memory

    Science.gov (United States)

    McCauley, Joseph L.

    2010-08-01

    A Markov process, by definition, cannot depend on any previous state other than the last observed state. An Ito process implies the Fokker-Planck and Kolmogorov backward time partial differential eqns. for transition densities, which in turn imply the Chapman-Kolmogorov eqn., but without requiring the Markov condition. We present a class of Ito process superficially resembling Markov processes, but with 1-state memory. In finance, such processes would obey the efficient market hypothesis up through the level of pair correlations. These stochastic processes have been mislabeled in recent literature as 'nonlinear Markov processes'. Inspired by Doob and Feller, who pointed out that the ChapmanKolmogorov eqn. is not restricted to Markov processes, we exhibit a Gaussian Ito transition density with 1-state memory in the drift coefficient that satisfies both of Kolmogorov's partial differential eqns. and also the Chapman-Kolmogorov eqn. In addition, we show that three of the examples from McKean's seminal 1966 paper are also nonMarkov Ito processes. Last, we show that the transition density of the generalized Black-Scholes type partial differential eqn. describes a martingale, and satisfies the ChapmanKolmogorov eqn. This leads to the shortest-known proof that the Green function of the Black-Scholes eqn. with variable diffusion coefficient provides the so-called martingale measure of option pricing.

    As usual, being an even year, the 23rd IAEA Fusion Energy Conference took place at Daejeon, Korea. The event was notable not just for the quality of the presentations but also for the spectacular opening ceremony, in the presence of the Prime Minister, Kim Hwang-sik. The Prime Minister affirmed the importance of research into fusion energy research and pledged support for ITER. Such political visibility is good news, of course, but it brings with it the obligation to perform. Fortunately, good performance was much in evidence in the papers presented at the conference, of which a significant proportion contain 'ITER' in the title. Given this importance of ITER and the undertaking by the Nuclear Fusion journal to publish papers associated with Fusion Energy Conference presentations, the Nuclear Fusion Editorial Board has decided to adopt a simplified journal scope that encompasses technology papers more naturally. The scope is available from http://iopscience.iop.org/0029-5515/page/Journal%20information but is reproduced here for clarity: Nuclear Fusion publishes articles making significant advances to the field of controlled thermonuclear fusion. The journal scope includes: the production, heating and confinement of high temperature plasmas; the physical properties of such plasmas; the experimental or theoretical methods of exploring or explaining them; fusion reactor physics; reactor concepts; fusion technologies. The key to scope acceptability is now '....significant advances....' rather than any particular area of controlled thermonuclear fusion research. It is hoped that this will make scope decisions easier for the Nuclear Fusion office, the referees and the Editor.The Nuclear Fusion journal has continued to make an important contribution to the research programme and has maintained its position as the leading journal in the field. This is underlined by the fact that Nuclear Fusion has received an impact factor of 4.270, as listed in ISI's 2009 Science Citation

The awards were presented by the IAEA Deputy Director General, Werner Burkart, and the Chairman of the Board of Editors, Mitsuru Kikuchi, on 16 October 2008 at the 22nd IAEA Fusion Energy Conference in Geneva, Switzerland. Given the topicality of these papers for the ITER design, it is a matter of pride to the journal that the work should be published in Nuclear Fusion. Reviews Like many who have worked for a long time in the field, I still make use of Nuclear Fusion Reviews that go back 20 or 30 years. It is particularly useful, therefore, that the Board of Editors has been working to re-activate the review programme. The first fruits will appear in this issue, in the form of `A review of zonal flow experiments', by Akihide Fujisawa. The special procedures for Reviews should be noted: most specifically that they should normally be commissioned by the Board of Editors. However, not only is the Board of Editors working on a programme but I am sure that they would be pleased to consider suggestions for review subjects. Letters The reputation of Nuclear

    Full Text Available The Ito cell (fat-storing cell is a cell lying in perisinusoidal space of liver. The function of Ito cell is expanding from a site of fat-storing site to a center of extracellular matrix metabolism and mediator production in the liver. This study was performed in order to evaluate the Ito cells in cholestatic condition. The artificial cholestatic was conducted by ligation of extrahepatic bile ducts (bile duct ligation = BDL in broilers. The results showed that BDL induced bile congestion, fibrosis, proliferation of Ito cells and intrahepatic bile ductules. Immunohistochemistry demonstrated that Ito cells were scattered throughout the fibrotic areas, and larger in size with more extensive immunoreactivity than those in normal livers. Ultrastructural study demonstrated that Ito cells were closely associated with the production of extracellular collagen fibers. Ito cells actively react against hepatocytic injuries, especially in fibrogenesis of cholestatic livers.

    An indium tin oxide (ITO)-coated vertically aligned nanowire array is fabricated, and the field emission characteristics of the nanowire array are investigated. An array of vertically aligned nanowires is considered an ideal structure for a field emitter because of its parallel orientation to the applied electric field. In this letter, a vertically aligned nanowire array is fabricated by modified conventional UV lithography and coated with 0.1-μm-thick ITO. The turn-on electric field intensity is about 2.0 V/μm, and the field enhancement factor, β, is approximately 3,078 when the gap for field emission is 0.6 μm, as measured with a nanomanipulator in a scanning electron microscope.

    Thermal and fast neutrons were measured inside the West Zone II building on Ito Campus for the assessment of terrestrial neutrons in a stand alone concrete building. Ratios of count rate of thermal neutrons to that of fast neutrons were almost constant inside the building. The contribution of fast neutrons across outside wall has been discussed. A simple method to estimate the neutron flux near the outside wall has been proposed.

    The authors investigated the atmospheric tree pollen dispersion in Ito City, Shizuoka Prefecture for 12 years for the purpose of the prophylaxis and treatment of pollinosis. We set up a Durham sampler on the rooftop of the three-story building in Ito City, and counted atmospheric pollen grouping first, Taxodiaceae and Cupressaceae; second, Pinaceae and Podocarpaceae; third, Betulaceae and Ulmaceae; last, Fagaceae. The counts of atmospheric tree pollen on season and the weather from January to June were treated statistically and analyzed on the computer program Microsoft Excel. Each average and SD of total pollen count was, in order, 7079±6503 count/cm(2), 502±146 count/cm(2), 891±480 count/cm(2), 906±481 count/cm(2). The last summer weather correlates to the atmospheric pollen count of Taxodiaceae, Cupressaceae, Betulaceace and Ulmaceae. The atmospheric pollen count of Taxodiaceae and Cupressaceae in spring is influenced by the weather; their atmospheric pollen count is reduced by a heavy rain or a heavy snow out of season. The atmospheric pollen count of Pinaceae, Podocarpaceae and Fagaceae does not relate to the weather. As a result of having examined the relations between the count of the atmospheric pollen and the weather in Ito City, I recognized relations in Taxodiaceae, Cupressaceae, Pinaceae and Podocarpaceae, but there were not the relations of intentionality in Betulaceae, Ulmaceae and Fagaceae.

    Full Text Available This time our focus section features work from the first conference hosted by IJCV. In 2011 Donatella della Porta and Gary LaFree, both members of the journal’s advisory board, brought together in Bielefeld experts from around the world to thoroughly debate the question of radicalization and de-radicalization. In contrast to prior approaches that mostly focused on the context of terrorism, the aim of this focus section is to present work employing new theoretical and methodological approaches to generate findings that go well beyond terrorism and related phenomena and thus contribute to a more comprehensive understanding of the processes, dynamics, and mechanisms of radicalization and de-radicalization. Our heartfelt thanks go to the two guest editors – as well as the entire conference team – for realising this ambitious project and for putting together this collection of papers.The open section contains two articles of additional interest. Rafi Nets-Zehngut uses the example of the 1948 Palestinian exodus to describe the characteristics of internal and external collective memories in Israeli society. The section closes with a contribution by Claudia Diehl and Jan-Philipp Steinmann who explore the impact of the release and public discussion of Thilo Sarrazin’s book Deutschland schafft sich ab (Germany abolishes itself on public perception of immigrants in Germany.

  16. Rectified photocurrent in a planar ITO/graphene/ITO photodetector on SiC by local irradiation of ultraviolet light

    A rectified photocurrent behaviour is demonstrated in a simple planar structure of ITO-graphene-ITO formed on a SiC substrate when an ultraviolet (UV) light is locally incident on one of the edges between the graphene and ITO electrode. The photocurrent has similar characteristics as those of a vertical structure graphene/semiconductor junction photodiode, but is clearly different from those found in a planar structure metal-graphene-metal device. Furthermore, the device behaves multi-functionally as a photodiode with sensitive UV photodetection capability (responsivity of 11.7 mA W-1 at 0.3 V) and a self-powered UV photodetector (responsivity of 4.4 mA W-1 at zero bias). Both features are operative in a wide dynamic range and with a fast speed of response in about gigahertz. The linear I-V behaviour with laser power at forward bias and cutoff at reverse bias leads to a conceptual photodiode, which is compatible with modern semiconductor planar device architecture. This paves a potential way to realize ultrafast graphene planar photodiodes for monolithic integration of graphene-based devices on the same SiC substrate.

    Highlights: • Polymeric PET fibers were conductive modified by ITO and the subsequent Ag coating. The conductive PET-ITO-Ag fiber has the surface resistivity as low as 0.23 mΩ cm. The PET-ITO-Ag fiber was used as a basal material to plant vertical ZnO nanorods. - Abstract: We studied the vertical ZnO nanorods grown on conductive conventional polyethylene terephthalate (PET) fibers which are prepared by electroless silver depositing on tin-doped indium oxide (ITO) coated PET fibers through an efficient and low-cost green approach. The PET fibers were firstly functionalized with a layer of ITO gel synthesized through a sol–gel process at rather low temperature, simply by immersing the fibers into ITO sol for several minutes followed by gelation at 120 °C. Once the ITO gel layer surface was activated by SnCl{sub 2}, a continuous, uniform, and compact layer of silver was carried out on the surface of the PET-ITO fibers through electroless plating operation at room temperature. The as-prepared PET-ITO-Ag fibers had good electrical conductivity, with surface resistivity as low as 0.23 mΩ cm. The overall procedure is simple, efficient, nontoxic, and controllable. The conductive PET-ITO-Ag fiber was used successfully as a flexible basal material to plant vertical ZnO nanorods through controlling the seeding and growth processes. The morphology of the PET-ITO, PET-ITO-Ag, and PET-ITO-Ag-ZnO fibers were observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Undergone the whole process, although the tensile strength of the fiber decreased slightly, they may still exert their applications in flexible electronic such as photovoltaic and piezoelectric devices.

    Full Text Available Abstract Background Biological Computer Aided Design (bioCAD assists the de novo design and selection of existing genetic components to achieve a desired biological activity, as part of an integrated design-build-test cycle. To meet the emerging needs of Synthetic Biology, bioCAD tools must address the increasing prevalence of combinatorial library design, design rule specification, and scar-less multi-part DNA assembly. Results We report the development and deployment of web-based bioCAD software, DeviceEditor, which provides a graphical design environment that mimics the intuitive visual whiteboard design process practiced in biological laboratories. The key innovations of DeviceEditor include visual combinatorial library design, direct integration with scar-less multi-part DNA assembly design automation, and a graphical user interface for the creation and modification of design specification rules. We demonstrate how biological designs are rendered on the DeviceEditor canvas, and we present effective visualizations of genetic component ordering and combinatorial variations within complex designs. Conclusions DeviceEditor liberates researchers from DNA base-pair manipulation, and enables users to create successful prototypes using standardized, functional, and visual abstractions. Open and documented software interfaces support further integration of DeviceEditor with other bioCAD tools and software platforms. DeviceEditor saves researcher time and institutional resources through correct-by-construction design, the automation of tedious tasks, design reuse, and the minimization of DNA assembly costs.

The acceptance rate of the 404 manuscripts whose editorial process has been concluded was 32.3% (originals, 22.4%). We asked for 315 revisions to 240 reviewers and we received 53.3% revisions in less than two weeks (10.4 days). The mean time to adopt an editorial decision for all manuscripts («accepted»/«rejected») has been 18,3 (less than half than in 2009). For «originals» this figure has dropped from 56,6 days in 2009 to 26.6 days in 2014. The mean time elapsed from manuscript reception to its on-line publication was 103 days. In 2014 the collaboration with the working groups from the Internal Medicine Spanish Foundation (FEMI) has reported 11 published manuscripts. In July 2014 we were informed that the Journal Citation Reports gave Rev Clin Esp an Impact Factor of 1,314 (year 2013). This Impact Factor without self-citations would have been 0.705 (in 2009 the global impact factor was 0,584). With the Editorial Committee farewell we welcome the new editorial team and we sincerely thank the SEMI Steering Committee, our colleagues, journal officers, reviewers, readers and authors that since 2009 have trusted on our editorial work.

    The editors of Revista Clínica Española(Rev Clin Esp) inform on their editorial activity during the last 12 months: (a) objectives and attainments, (b) editorial activity, and (c) objectives for 2014. In 2013 the most relevant modification concerning the editorial activity has been the translation into English of the 5 manuscripts with abstract contained in each issue (http://www.revclinesp.es/). From the first January to the 30th September 2013 we received 458 manuscripts (50.9 manuscripts per month), a similar figure to that obtained in 2012 (51.1 manuscripts per month). The acceptance rate of the 443 manuscripts whose editorial process has been concluded was 23.7% (originals, 11.8%). We asked for 253 revisions to 186 reviewers and we received 74.4% revisions in less than 2 weeks (10.9 days). The mean time to adopt an editorial decision for all manuscripts («accepted»/«rejected») has been 20,3 (half than in 2009). For «originals» this figure has dropped from 56.6 days in 2009 to 22.5 days in 2013. The mean time elapsed from manuscript reception to its on-line publication was 94.8 days in 2013 (110.5 in 2012 and 155.8 in 2011). In 2013 the collaboration with the working groups from the Internal Medicine Spanish Foundation has reported 17 published manuscripts. In 2013 we were informed that the Journal Citation Reports excluded Rev Clin Esp from its impact factor journal list due to its elevated self-citations. We have taken a number of actions to reduce self-citations and we expect to be a minority in 2014. Some other data concerning the editorial policy are encouraging. In this sense, manuscript citation to Rev Clin Esp published articles has seen a substantial increase from 19% in 2008 to 29% in 2012. We work to achieve the digitalization of Rev Clin Esp from 1940 to 1999 (the journal is already digitalized since 2000). The continuous renewal of the journal sections and the working groups collaboration are necessary elements to make our journal, each day

    We present two strategies to minimize laser damage in transparent conductive films. The first consists of improving heat dissipation by selection of substrates with high thermal diffusivity or by addition of capping layer heatsinks. The second is reduction of bulk energy absorption by lowering free carrier density and increasing mobility, while maintaining film conductance with thicker films. Multi-pulse laser damage tests were performed on tin-doped indium oxide (ITO) films configured to improve optical lifetime damage performance. Conditions where improvements were not observed are also described. When bulk heating is not the dominant damage process, discrete defect-induced damage limits damage behavior.

    Dear authors and reviewers of articles for Measurement Science and Technology, I would like to thank all those who have published papers with us in 2010, and special thanks go to those of you who have kindly reviewed articles for the journal. I would also like to take this opportunity to update you on some of the developments on the journal and look ahead to 2011. As many of you are no doubt aware, our impact factor (a measure of the average number of times recent papers are referred to by others) is currently 1.317. This is often taken as an indication of the quality and relevance of recently published research, and although as readers we develop our own instinct for journals of high quality, it is gratifying as an Editor to see the data from an independent organization (Thomson ISI) agreeing with my own assessment. Measurement Science and Technology is a journal with a broad scope covering new measurement techniques in all fields of science and engineering. I therefore find it particularly enjoyable to read summaries of recent research in our strong topical review programme as these cover many varied topics of interest. In 2010 several interesting articles by international leaders in their field were published, for example: Single-photon generation and detection, by G S Buller and R J Collins of Heriot-Watt University [1]. Fluorescence lifetime imaging microscopy in life sciences, by Jan Willem Borst and Antonie J W G Visser, from the Microspectroscopy Centre of Wageningen University [2]. Biological and chemical sensors for cancer diagnosis, by Elfriede Simon of Siemens AG [3]. I hope that these articles, and the others published in 2010 and now in 2011, will provide a useful overview for our readers, and be helpful to new researchers. When speaking to young researchers I am particularly aware that having their articles published in a timely fashion is important, and I am pleased that our publication times are highly competitive, with most authors receiving a

  9. Optimizing ITO for incorporation into multilayer thin film stacks for visible and NIR applications

    Indium Tin Oxide, ITO, is the industry standard for transparent conductive coatings. As such, the common metrics for characterizing ITO performance are its transmission and conductivity/resistivity (or sheet resistance). In spite of its recurrent use in a broad range of technological applications, the performance of ITO itself is highly variable, depending on the method of deposition and chamber conditions, and a single well defined set of properties does not exist. This poses particular challenges for the incorporation of ITO in complex optical multilayer stacks while trying to maintain electronic performance. Complicating matters further, ITO suffers increased absorption losses in the NIR - making the ability to incorporate ITO into anti-reflective stacks crucial to optimizing overall optical performance when ITO is used in real world applications. In this work, we discuss the use of ITO in multilayer thin film stacks for applications from the visible to the NIR. In the NIR, we discuss methods to analyze and fine tune the film properties to account for, and minimize, losses due to absorption and to optimize the overall transmission of the multilayer stacks. The ability to obtain high transmission while maintaining good electrical properties, specifically low resistivity, is demonstrated. Trade-offs between transmission and conductivity with variation of process parameters are discussed in light of optimizing the performance of the final optical stack and not just with consideration to the ITO film itself.

    Monodisperse 11 nm indium tin oxide (ITO) nanocrystals (NCs) were synthesized by thermal decomposition of indium acetylacetonate, In(acac)(3), and tin bis(acetylacetonate)dichloride, Sn(acac)(2)Cl(2), at 270 °C in 1-octadecene with oleylamine and oleic acid as surfactants. Dispersed in hexane, these ITO NCs were spin-cast on centimeter-wide glass substrates, forming uniform ITO NC assemblies with root-mean-square roughness of 2.9 nm. The assembly thickness was controlled by ITO NC concentrations in hexane and rotation speeds of the spin coater. Via controlled thermal annealing at 300 °C for 6 h under Ar and 5% H(2), the ITO NC assemblies became conductive and transparent with the 146 nm-thick assembly showing 5.2 × 10(-3) Ω·cm (R(s) = 356 Ω/sq) resistivity and 93% transparency in the visible spectral range--the best values ever reported for ITO NC assemblies prepared from solution phase processes. The stable hexane dispersion of ITO NCs was also readily spin-cast on polyimide (T(g) ~360 °C), and the resultant ITO assembly exhibited a comparable conductivity and transparency to the assembly on a glass substrate. The reported synthesis and assembly provide a promising solution to the fabrication of transparent and conducting ITO NCs on flexible substrates for optoelectronic applications.

    The last few decades have seen a significant improvement in organic semiconductor technology related to solar cell, light emitting diode and display panels. The material and structure of the transparent electrode is one of the major concerns for superior performance of devices such as OPV, OLED, touch screen and LCD display. Commonly used ITO is now restricted due to scarcity of indium, its poor mechanical properties and rigidity, and mismatch of energy levels with the active layer. Nowadays DMD (dielectric-metal-dielectric) structure is one of the prominent candidates as alternatives to ITO based electrode. We have used solution based spin coated polymer layer as the dielectric layer with silver thin film embedded in between to make a polymer-metal-polymer (PMP) structure for TCE applications. The PMP structure shows low resistivity (2.3 x 10-4Ω-cm), high carrier concentration (2.9 x 1021 cm-3) and moderate transparency. The multilayer PMP structure is characterized with XRD, AFM and Hall measurement to prove its suitability for opto-electronic device applications.

    Hybrid organic-inorganic heterojunction between polyaniline and ITO film coated on flexible polyethylene terephthalate (PET) substrate has been prepared through vapor phase polymerization process. Polaron and bipolaron like defect states induced hole transport and exceptional mobility makes polyaniline a noble hole transport layer. Thus a p-n junction has been obtained between the hole transport layer of polyaniline and highly conductive n-type layer of ITO film. The synthesis process was carried out using FeCl3 as polymerizing agent in the oxidative chemical polymerization process. The prepared polyaniline has been found to be crystalline on characterization through X-ray diffraction measurement. X-ray photoelectron spectroscopic measurements were done for compositional analysis of the prepared film. The UV-vis-NIR absorbance spectra obtained for polyaniline shows the characteristics absorbance as observed for highly conductive polyaniline and confirms the occurrence of partially oxidized emeraldine form of polyaniline. The energy band gap of the polyaniline has been obtained as 2.52 eV, by analyzing the optical transmittance spectra. A rectifying behavior has been observed in the electrical J-V plot, which is of great significance in designing polymer based flexible electronic devices.

    Full Text Available The present work proposes a method to fabricate indium tin oxide (ITO particles using precursor particles synthesized with a combination of a homogeneous precipitation method and a seeding technique, and it also describes their electronic conductivity properties. Seed nanoparticles were produced using a co-precipitation method with aqueous solutions of indium (III chloride, tin (IV chloride aqueous solution and sodium hydroxide. Three types of ITO nanoparticles were fabricated. The first type was fabricated using the co-precipitation method (c-ITO. The second and third types were fabricated using a homogeneous precipitation method with the seed nanoparticles (s-ITO and without seeds (n-ITO. The as-prepared precursor particles were annealed in air at 500 °C, and their crystal structures were cubic ITO. The c-ITO nanoparticles formed irregular-shaped agglomerates of nanoparticles. The n-ITO nanoparticles had a rectangular-parallelepiped or quasi-cubic structure. Most s-ITO nanoparticles had a quasi-cubic structure, and their size was larger than the n-ITO particles. The volume resistivities of the c-ITO, n-ITO and s-ITO powders decreased in that order because the regular-shaped particles were made to strongly contact with each other.

    ITO/CdS/ZnO interface composite films were successfully prepared by subsequent electrodeposition of CdS and ZnO onto indium tin oxide (ITO) glass substrates. The obtained ITO/CdS/ZnO composite films were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-Vis spectroscopy. The photocatalytic activity of ITO/CdS/ZnO composite films were investigated using methyl orange (MO) as a model organic compound under UV light irradiation. The influence of operating parameters on MO degradation including initial concentration of MO, pH value of solution, and inorganic anion species over the composite films were examined. A blue shift of absorption threshold was observed for the ITO/CdS/ZnO film in comparison with ITO/ZnO film. ITO/CdS/ZnO composite films prepared under specific conditions showed a higher photocatalytic activity than that of ITO/ZnO films. It was also found that the photocatalytic degradation of MO on the composite films followed pseudo-first order kinetics.

    Sn doped indium oxide (ITO) single layer films and ITO/Copper (Cu) bi-layer films were prepared on polycarbonate substrates by DC and RF magnetron sputtering without intentional substrate heating. In order to consider the influence of the Cu underlayer on the optoelectrical properties and microstructures of the films, the thickness of the Cu bottom layer in the ITO/Cu films was varied from 5 to 20 nm. Conventional ITO films had a constant optical transmittance of 74% and an electrical resistivity of 3.1 x 10{sup -3} {omega} cm, while ITO/Cu films had different optoelectrical properties that were influenced by the thickness of the Cu bottom layer. The lowest electrical resistivity, 5.7 x 10{sup -5} {omega} cm, was obtained from ITO 80 nm/Cu 20 nm films and the highest optical transmittance of 72%, was obtained from the ITO 95 nm/Cu 5 nm films. From the figure of merit ({phi}{sub TC}) which is defined by {phi}{sub TC} = T{sup 10}/R{sub s}, where T is the optical transmittance at 550 nm and R{sub s} is the sheet resistance, it can be concluded that the most effective Cu thickness in the ITO/Cu films on the optoelectrical properties was 5 nm.

  10. The Influence of Laser Induced Consolidation on the Ablation Threshold of Nanoparticulate ITO-layers

    Science.gov (United States)

    Mikschl, Florian; Baum, Marcus; Heberle, Johannes; Alexeev, Ilya; Schmidt, Michael

    Indium tin oxide (ITO) is one of the few materials, which combines optical transparency in the wavelength range of visible light and electrical conductivity. It offers a wide range of applications in the field of optoelectronic devices such as solar cells or displays. To the present day, ITO is commonly deposited in a vacuum environment. Deposition under vacuum atmosphere is a cost-intensive process and not compatible with modern manufacturing techniques, like roll-to-roll processing. To overcome this limitation we propose the generation of ITO layers by deposition of ITO nanoparticles under atmospheric conditions.For the generation of functional devices structured layers are required. The exact damage threshold of nanoparticulate ITO layers is essential to minimize influence of the structuring process on the substrate.In our measurements we used three different substrates, spin coated layers, annealed layers and consolidated layers.

    Graphical abstract: We report a simple and controllable synthesis of CuO-nanoparticle-modified ITO by employing a combination of ion-implantation and annealing methods for the first time. The optimum CuO/ITO electrode shows uniform morphology, highly accessible surface area, long-term stability and excellent electrochemical performance towards biomolecules such as glucose in alkaline solution. - Highlights: • Controllably annealed CuO/ITO electrode was synthesized for the first time. • The generation mechanism of CuO nanoparticles is revealed. • The optimum CuO/ITO electrode shows excellent electrochemical performance. • A reference for the controllable preparation of other metal oxide nanoparticles. - Abstract: In this paper, we report a facile and controllable two-step approach to produce indium tin oxide electrodes modified by copper(II) oxide nanoparticles (CuO/ITO) through ion implantation and annealing methods. After annealing treatment, the surface morphology of the CuO/ITO substrate changed remarkably and exhibited highly electroactive sites and a high specific surface area. The effects of annealing treatment on the synthesis of CuO/ITO were discussed based on various instruments’ characterisations, and the possible mechanism by which CuO nanoparticles were generated was also proposed in this work. Cyclic voltammetric results indicated that CuO/ITO electrodes exhibited effective catalytic responses toward glucose in alkaline solution. Under optimal experimental conditions, the proposed CuO/ITO electrode showed sensitivity of 450.2 μA cm{sup −2} mM{sup −1} with a linear range of up to ∼4.4 mM and a detection limit of 0.7 μM (S/N = 3). Moreover, CuO/ITO exhibited good poison resistance, reproducibility, and stability properties.

    Airborne pollen was examined in Ito City, Shizuoka for the purpose of treatment and prophylaxis pollen allergies because the patients with pollen allergy to herbaceous plants have recently increased. Setting up a Durham's sampler, we measured airborne pollen identified and classified: Poaceae, Polygonaceae, Amaranthaceae, Urticaceae, Cannabaceae, Ambrosia and Artemisia indica.We studied whether each airborne pollen count has something to do with weather condition (2004-2015). Average total airborne Poaceae pollen count and standard deviation from January to June was 19.4±5.5 cells/cm(2), average total airborne Polygonaceae pollen count and standard deviation from April to September was 11.6±13.4 cells/cm(2). Airborne Poaceae, Amaranthaceae, Cannabaceae, Uriticaceae. Ambrosia and Artamisia indica pollen count from July to Deccember in order: 34.0±15.5 cells/cm(2), 1.3±1.1 cells/cm(2), 8.7±6.4cells/cm(2), 4.9±6.4 cells/cm(2), 10.5±7.8 cells/cm(2), and 13.6±16.3 cells/cm(2).Cannabaceae admitted that its airborne pollen count has negative correlation to the rainfall.Artemisia indica admitted that its airborne pollen count has negative correlation to the average temperature. Herbaceous plants pollen doesn't cause allergies because it is much less than tree pollen in ItoCity.It is thought that the diversity of the plants keep the people from having a serious allergy to pollen with awarm weather in this area.

  7. Graphical Editor of the DDS Topology Configuration

    CERN Document Server

    Rusinov, Aleksandar

    2015-01-01

    An editor for the DDS topology configuration is created to allow the viewing of an existing topology, the editing of a topology, the creation of a new topology and the saving of a topology as a topology language XML file to be run directly on DDS or to be reloaded again for further editing. The development of the editor was started at GSI Darmstadt at the end of last year. The editor is designed as a web application that works on the client side. Recent and powerful JavaScript libraries were used – ReactJS and JointJS. It has two menus for editing – one for the declarative part and another for the executable part. A graph visualisation of the topology has also been developed and implemented fully to the editor. The output files have been tested and fully verified on the DDS. Future work will involve representation of the pipeline process and investigation on behavior when larger and more sophisticated topologies are used.

    Stansifer, Ryan

    2000-01-01

    In this project we continued the development of a visual editor in the Java programming language to create screens on which to display real-time data. The data comes from the numerous systems monitoring the operation of the space shuttle while on the ground and in space, and from the many tests of subsystems. The data can be displayed on any computer platform running a Java-enabled World Wide Web (WWW) browser and connected to the Internet. Previously a special-purpose program bad been written to display data on emulations of character-based display screens used for many years at NASA. The goal now is to display bit-mapped screens created by a visual editor. We report here on the visual editor that creates the display screens. This project continues the work we bad done previously. Previously we had followed the design of the 'beanbox,' a prototype visual editor created by Sun Microsystems. We abandoned this approach and implemented a prototype using a more direct approach. In addition, our prototype is based on newly released Java 2 graphical user interface (GUI) libraries. The result has been a visually more appealing appearance and a more robust application.

    Chen, I-Min A.; Markowitz, V.M.; Pang, F.; Ben-Shachar, O.

    1993-07-01

    This document describes an X-window based Schema Editor for the Object-Protocol Model (OPM). OPM is a data model that supports the specification of complex object and protocol classes. objects and protocols are qualified in OPM by attributes that are defined over (associated with) value classes. Connections of object and protocol classes are expressed in OPM via attributes. OPM supports the specification (expansion) of protocols in terms of alternative and sequences of component (sub) protocols. The OPM Schema Editor allows specifying, displaying, modifying, and browsing through OPM schemas. The OPM Schema Editor generates an output file that can be used as input to an OPM schema translation tool that maps OPM schemas into definitions for relational database management systems. The OPM Schema Editor was implemented using C++ and the X11 based Motif toolkit, on Sun SPARCstation under Sun Unix OS 4.1. This document consists of the following parts: (1) A tutorial consisting of seven introductory lessons for the OPM Schema Editor. (2) A reference manual describing all the windows and functions of the OPM Schema Editor. (3) An appendix with an overview of OPM.

    2015-01-01

    Full Text Available Indium tin oxide (ITO thin films were grown on glass substrates by direct current (DC reactive magnetron sputtering at room temperature. Annealing at the optimal temperature can considerably improve the composition, structure, optical properties, and electrical properties of the ITO film. An ITO sample with a favorable crystalline structure was obtained by annealing in fixed oxygen/argon ratio of 0.03 at 400°C for 30 min. The carrier concentration, mobility, resistivity, band gap, transmission in the visible-light region, and transmission in the near-IR regions of the ITO sample were -1.6E+20 cm−3, 2.7E+01 cm2/Vs, 1.4E-03 Ohm-cm, 3.2 eV, 89.1%, and 94.7%, respectively. Thus, annealing improved the average transmissions (400–1200 nm of the ITO film by 16.36%. Moreover, annealing a copper-indium-gallium-diselenide (CIGS solar cell at 400°C for 30 min in air improved its efficiency by 18.75%. The characteristics of annealing ITO films importantly affect the structural, morphological, electrical, and optical properties of ITO films that are used in solar cells.

    Graphical abstract: The effect of O{sub 2} plasma treatment on the surface and the work function of ITO films. - Highlights: • ITO films were prepared on the glass substrate by RF magnetron sputtering method. • Effects of O{sub 2} plasma treatment on the properties of ITO films were investigated. • The work function of ITO film was changed from 4.67 to 5.66 eV by plasma treatment. - Abstract: The influence of oxygen plasma treatment on the electro-optical and structural properties of indium-tin-oxide films deposited by radio frequency magnetron sputtering method were investigated. The films were exposed at different O{sub 2} plasma powers and for various durations by using the plasma enhanced chemical vapor deposition (PECVD) system. The resistivity of the ITO films was almost constant, regardless of the plasma treatment conditions. Although the optical transmittance of ITO films was little changed by the plasma power, the prolonged treatment slightly increased the transmittance. The work function of ITO film was changed from 4.67 eV to 5.66 eV at the plasma treatment conditions of 300 W and 60 min.

    Highlights: • PBTh–MnO{sub 2} composites are prepared by electro-polymerization of bithiophene on ITO. • Photocurrent of ITO/PBTh–MnO{sub 2} films is three times higher than that of ITO/PBTh substrate. • Electrochemical gap, HOMO and LUMO potentials are determined. • ITO/PBTh–MnO{sub 2} films can be used as a new active material in solar cells. - Abstract: Manganese dioxide is synthesized by reduction reaction of potassium permanganate with hydrogen peroxide. The as-synthesized α-MnO{sub 2} is characterized by powder X-ray diffraction and infrared spectroscopy. The MnO{sub 2} particles are used to prepare composite films containing polybithophene (PBTh) on indium tin oxide (ITO) glass substrates. The composite films ITO/PBTh–MnO{sub 2} are obtained by electro-polymerization of bithiophene in the presence the α-MnO{sub 2} particles dispersed in the electrolytic solution. The XRD and SEM analyses show that the α-MnO{sub 2} particles of size in the range 100–300 nm are incorporated in the polymer. The films are characterized by cyclic voltammetry impedance spectroscopy, UV–vis spectroscopy and scanning electron microscopy. As a result, the electrochemical gap and the optical gap are shifted by the incorporation of MnO{sub 2} from 2.15 eV for ITO/PBTh to 1.88 eV for ITO/PBTh–MnO{sub 2}, while the electrical conductivity decreases from 195.35 S/cm for ITO/PBTh down to 0.047 S/cm for ITO/PBTh–MnO{sub 2} at the highest MnO{sub 2} investigated. The photo-electrochemical measurements also indicate that the ITO/PBTh–MnO{sub 2} films show a photocurrent that is three times higher than that of ITO/PBTh substrate to reach 20.6 μA cm{sup −2}, so that such a composite can be used as a new active material in solar cells.

  17. Evolutionary theory in letters to the editor.

    Science.gov (United States)

    Silva, Eric Orion; Lowe, Clayton Cory

    2015-05-01

    This research note presents the results of a content analysis of 234 letters to the editors that discuss evolutionary theory and were published in American newspapers. We find that letters to the editor both support and hinder the cause of teaching evolutionary theory in American secondary schools. On the one hand, anti-evolutionary theory messages are marginalized in the letters section. This marginalization signals a low level of legitimacy for creationism. It might also contribute to the sense of tension that sustains creationist identities. On the other hand, relatively few letters explicitly note the fact that scientists or the scientific community accept evolution. Interestingly, the obscuration of the scientific community's support for evolutionary theory occurs both in letters supporting and opposing evolutionary theory. © The Author(s) 2014.

    2016-11-01

    Highlights: • The work function of ITO was reduced by plasma treatment. • The reduction of the work function was attributed to the variation in chemical component of ITO surface. • The inverted solar cell without electron transport layer was fabricated using plasma-treated ITO. • Optimal power conversion efficiency of 3.22% was achieved. - Abstract: In this paper, we investigated the performance of inverted organic solar cells (OSCs) with plasma-treated indium tin oxide (ITO) as the cathode for omitting an electron transport layer. The Ar plasma was produced by capcitively coupled plasma setup under 20 Pa chamber pressure. For the device with the structure of plasma-treated ITO/P3HT:PCBM/MoO{sub 3}/Ag, a power conversion efficiency (PCE) of 3.22% was achieved, whereas PCE of 1.13% was recorded from the device fabricated with the pristine ITO. The photovoltaic performance was found to be dependent on the applied power of plasma. After analyzing by atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS), we concluded that the chemical component variation of ITOs surface resulted in the decrease of ITO work function, which meant that the ITO Fermi level became shallow relative to the vacuum level. The low work function of ITO should be responsible for the improvement of inverted OSCs because of the better energy level alignment between ITO and the photoactive layer.

  2. Resonances and permittivity dispersion effects in ITO nanorod arrays

    CERN Document Server

    Li, Shi-Qiang; Ketterson, John B; Chang, Robert P H

    2014-01-01

    In the nanophotonics community, there is an active discussion regarding the origin of the selective absorption/scattering of light by the resonances with nanorod arrays. Here we report a study of the resonances in ordered indium-tin-oxide (ITO) nanorod arrays from the perspective of waveguides. We discover that with only 2.4% geometrical coverage, the micron-length nanorod arrays strongly interact with light across an extra-wide band from visible to mid-infrared resulting in less than 10% transmission at the first order destructive interference. Simulations show excellent agreement with our experimental observation. Near-field profile obtained from simulation reveals the electric field is mainly localized on the surfaces of the nanorods at all the resonances. Theoretical analysis is then applied to explain the resonances and it was found that the resonances in the visible are different from those in the infrared. The former resonances are the result of the interference between guided wave and wave propagated ...

    Efficient inverted polymer solar cells (PSCs) were constructed by utilizing a conjugated polyelectrolyte PF{sub EO}SO{sub 3}Na and zinc oxide to modify the indium tin oxide (ITO) electrode. The ITO electrode modified by PF{sub EO}SO{sub 3}Na and zinc oxide possesses high transparency, increased electron mobility, smoothened surface, and lower work function. PTB7:PC{sub 71}BM inverted PSCs containing the modified ITO electrode achieved a high power conversion efficiency (PCE) of 8.49%, exceeding that of the control device containing a ZnO modified ITO electrode (7.48%). Especially, PCE-10:PC{sub 71}BM inverted polymer solar cells achieved a high PCE up to 9.4%. These results demonstrate a useful approach to improve the performance of inverted polymer solar cells.

    Metamaterials that have broadband absorption at MIR frequencies, and yet, are transmitive at visible frequencies are fabricated using a semi-conducting Indium Tin Oxide (ITO) film as ground plane. The metamaterial absorber consists of an array of uniform aluminum disks separated by a Zinc Sulphide (ZnS) dielectric spacer layer from the ITO ground plane. The metamaterial was fabricated by a simple, cost-effective vapor deposition through a shadow mask. Compared with the usual metal/dielectric/metal tri-layer absorbers, the metal/dielectric/ITO absorber shows a peak absorbance of 98% and >70% over the mid-infrared regime from 4 to 7 μm. The broadband nature arises due to smaller dispersion in the dielectric permittivity of ITO compared to that of plasmonic metals at mid-infrared frequencies.

    A monolayer graphene coated glass slide and an indium tin oxide (ITO) coated glass slide with a planar-aligning polyimide layer were placed together to make a planar hybrid liquid crystal (LC) cell. The free-ion concentration in the LC was found to be significantly reduced in the graphene-ITO hybrid cell compared to that in a conventional ITO-ITO cell. The free-ion concentration was suppressed in the hybrid cell due to the graphene-electrode's ion trapping process. The dielectric anisotropy of the LC was found to increase in the hybrid cell, indicating an increase in the nematic order parameter of the LC due to the reduction of ionic impurities.

    and the ITO substrate was found to shift the work function of the electrode, and so modify the barrier to hole injection. Scanning Kelvin probe measurements show that the ITO work function is increased by 0.25 eV with a film of TNAP, while a C sub 6 sub 0 film is found to reduce the work function by a comparable amount. The former has been attributed to a charge-transfer effect resulting in Fermi level alignment between the ITO and the TNAP layer, however the latter is believed to result from both charge transfer and a covalent interaction between C sub 6 sub 0 and ITO. The performance of devices incorporating these modified ITO electrode are rationalised in terms of the work function modification, film thicknesses and the hole transport properties of the two films. Competition between the induced work function change and the increasingly significant tunnelling barrier with thickness means that device performance is not as good as that provided by the SAMs. Direct processing of the ITO substrate has also been...

    In this paper, we report a facile and controllable two-step approach to produce indium tin oxide electrodes modified by copper(II) oxide nanoparticles (CuO/ITO) through ion implantation and annealing methods. After annealing treatment, the surface morphology of the CuO/ITO substrate changed remarkably and exhibited highly electroactive sites and a high specific surface area. The effects of annealing treatment on the synthesis of CuO/ITO were discussed based on various instruments' characterisations, and the possible mechanism by which CuO nanoparticles were generated was also proposed in this work. Cyclic voltammetric results indicated that CuO/ITO electrodes exhibited effective catalytic responses toward glucose in alkaline solution. Under optimal experimental conditions, the proposed CuO/ITO electrode showed sensitivity of 450.2 μA cm-2 mM-1 with a linear range of up to ∼4.4 mM and a detection limit of 0.7 μM (S/N = 3). Moreover, CuO/ITO exhibited good poison resistance, reproducibility, and stability properties.

    The combination of graphene with conductive nanoparticles, forming graphene-nanoparticle hybrid materials, offers a number of excellent properties for advanced engineering applications. A novel and simple method was developed to deposit 10 wt% tin-doped indium tin oxide (ITO) nanoparticles on graphene. The method involved a combination of a solution-based environmentally friendly electroless deposition approach and subsequent vacuum annealing. A stable organic-free solution of ITO was prepared from economical salts of In(NO3) 3 · H2O and SnCl4. The obtained ITO nanostructure exhibited a unique architecture, with uniformly dispersed 25-35 nm size ITO nanoparticles, containing only the crystallized In2O3 phase. The synthesized ITO nanoparticles-graphene hybrid exhibited very good and reproducible optical transparency in the visible range (more than 85%) and a 28.2% improvement in electrical conductivity relative to graphene synthesized by chemical vapor deposition. It was observed that the ITO nanoparticles affect the position of the Raman signal of graphene, in which the D, G, and 2D peaks were redshifted by 5.65, 5.69, and 9.74 cm-1, respectively, and the annealing conditions had no significant effect on the Raman signatures of graphene.

    In this work, we report the morphological and electrochromic properties of electrochemically synthesized polyaniline (PANI) thin films on bare and modified indium-tin oxide (ITO) glass substrates. In the last case, the surface of ITO glass was covered by a self-assembled monolayer of N-phenyl-{gamma}-aminopropyl-trimethoxysilane (PAPTS). Atomic force microscopy images and perfilometry show that smoother and thinner PANI films were grown on PAPTS-modified ITO substrates. PANI-based electrochromic devices (ECDs) were assembled by using a viscous polymeric electrolyte (PE) of LiClO{sub 4} and polymethyl methacrylate (PMMA) co-dissolved in a mixture of propylene and ethylene carbonate. The architectural design of the devices was glass/ITO/PANI/PE/ITO/glass. A dual ECD was also prepared by collocating a poly(3-methylthiophene) (P3MT) thin film as a complementary electrochromic element. The effect of the PAPTS-modified ITO substrate is reflected in a higher optical transmittance at bleach state and a little less color change at 550 nm of PANI-based ECDs. (author)

    Surface roughness of indium-tin-oxide (ITO) film plays a crucial role on the performance of organic lighting emitting devices (OLEDs). A set of polishing apparatus with carbon dioxide snow jet as an actuating medium is established, and the surface polishing of ITO glass are carried out by this equipment. The surface morphology of ITO film is measured by using an atomic force microscope (AFM) before and after polishing treatment. The results show that before polishing, the mean values of Ra, Rpv and the RMS of the ITO surface are 1.463, 46.87 and 2.726 nm, respectively. After polishing, the value decreases to 0.773 nm, 19.51 and 1.078nm. It indicates that the polishing method is effective to reduce the ITO surface roughness. Another merit of this polishing method is that the polishing process has a cleaning effect to the ITO glass surface The performance of OLED can be enhanced and the production cost of device can be reduced.

    Transparent conductive Ga₂O₃/Cu/ITO films were prepared on the polyethylene terephthalate (PET) substrates using radio frequency (RF) and direct current (DC) magnetron sputtering without substrates heating. The effects of Ga₂O₃ layer thickness and Cu layer thickness on the optical and electrical properties of the Ga₂O₃/Cu/ITO films were studied. Changes in the optoelectrical properties of Ga₂O₃/Cu (4.2 nm)/ITO (30 nm) films were investigated with respect to the Ga₂O₃ layer thickness. The maximum transmission of 86%, the sheet resistance of 45 Ω/sq and the figure of merit of 8.89 × 10⁻²Ω⁻¹ were achieved for Ga₂O₃ (15 nm)/Cu (4.2 nm)/ITO (30 nm) films. The optoelectrical properties of the Ga₂O₃/Cu/ITO films were also significantly influenced by the thickness of the Cu layer. When the thickness of Cu layer was 3.7 nm, the maximum transmission of 87.6%, the sheet resistance of 50 Ω/sq and the figure of merit of 9.26 × 10⁻²Ω⁻¹ were obtained for the Ga₂O₃ (15 nm)/Cu/ITO (30 nm) films.

  16. Electro-Mechanical Coupling of Indium Tin Oxide Coated Polyethylene Terephthalate ITO/PET for Flexible Solar Cells

    Indium tin oxide (ITO) is the most widely used transparent electrode in flexible solar cells because of its high transparency and conductivity. But still, cracking of ITO on PET substrates due to tensile loading is not fully understood and it affects the functionality of the solar cell tremendously as ITO loses its conductivity. Here, we investigate the cracking evolution in ITO/PET exposed to two categories of tests. Monotonous tensile testing is done in order to trace the crack propagation in ITO coating as well as determining a loading range to focus on during our study. Five cycles test is also conducted to check the crack closure effect on the resistance variation of ITO. Analytical model for the damage in ITO layer is implemented using the homogenization concept as in laminated composites for transverse cracking. The homogenization technique is done twice on COMSOL to determine the mechanical and electrical degradation of ITO due to applied loading. Finally, this damage evolution is used for a simulation to predict the degradation of ITO as function in the applied load and correlate this degradation with the resistance variation. Experimental results showed that during unloading, crack closure results in recovery of conductivity and decrease in the overall resistance of the cracked ITO. Also, statistics about the crack spacing showed that the cracking pattern is not perfectly periodical however it has a positively skewed distribution. The higher the applied load, the less the discrepancy in the crack spacing data. It was found that the cracking mechanism of ITO starts with transverse cracking with local delamination at the crack tip unlike the mechanism proposed in the literature of having only cracking pattern without any local delamination. This is the actual mechanism that leads to the high increase in ITO resistance. The analytical code simulates the damage evolution in the ITO layer as function in the applied strain. This will be extended further to

    Full Text Available ITO-free semitransparent organic solar cells (OSCs based on MoO3/Ag anodes with poly(3-hexylthiophene and [6,6]-phenyl-C61-butyric acid methyl ester films as the active layer are investigated in this work. To obtain the optimal transparent (MoO3/Ag anode, ITO-free reference OSCs are firstly fabricated. The power conversion efficiency (PCE of 2.71% is obtained for OSCs based on the optimal MoO3 (2 nm/Ag (9 nm anode, comparable to that of ITO-based reference OSCs (PCE of 2.85%. Then based on MoO3 (2 nm/Ag (9 nm anode, ITO-free semitransparent OSCs with different thickness combination of Ca and Ag as the cathodes are investigated. It is observed from our results that OSCs with Ca (15 nm/Ag (15 nm cathode have the optimal transparency. Meanwhile, the PCE of 1.79% and 0.67% is obtained for illumination from the anode and cathode side, respectively, comparable to that of similar ITO-based semitransparent OSCs (PCE of 1.59% and 0.75% for illumination from the anode and cathode side, resp. (Sol. Energy Mater. Sol. Cells, 95, pp. 877–880, 2011. The transparency and PCE of ITO-free semitransparent OSCs can be further improved by introducing a light couple layer. The developed method is compatible with various substrates, which is instructive for further research of ITO-free semitransparent OSCs.

    Highlights: Black-Right-Pointing-Pointer Transparent conductive nanostructured ITO films. Black-Right-Pointing-Pointer Synthesis of ITO nanoparticles with corundum structure phase by the hydrothermal process. Black-Right-Pointing-Pointer Deposition of nanoparticulate ITO films by spin coating technique. Black-Right-Pointing-Pointer Curing of ITO films using UV irradiation at low temperatures. - Abstract: Corundum (hexagonal) structure indium tin oxide (h-ITO) nanocrystals have been synthesized by subjecting an aqueous solution of In and Sn chlorides (Sn/In 8 wt.%) to a hydrothermal process followed by annealing at 450 Degree-Sign C in forming gas for 1 h. The annealing temperature was selected based on thermo-gravimetric analysis (TGA) and differential thermal analysis (DTA) of the dried precipitated powder, which showed a stable weight and phase at temperatures above 420 Degree-Sign C. X-ray diffraction (XRD) patterns showed the formation of orthorhombic InOOH precipitates that is transformed, after annealing, into h-ITO nanocrystals with 32 nm average crystal size. For nanostructure film deposition, dispersed sols of the prepared nanocrystals were spun coated on glass substrates. The films were densified by UV irradiation, whilst four-probe method was used to measure its sheet resistance. A sheet resistance as low as 10.6 k{Omega} {open_square} have been reached. Scanning electron microscope (SEM) and high resolution transmission electron microscope (HRTEM) showed that the films have high surface roughness and nanopores. The transmittance spectra of the nanostructure films were measured in the UV-vis-NIR wavelength range. In addition to its low resistivity, nanostructure h-ITO films showed a wide range of transparency.

    Transparent thin-film Indium Tin Oxides (ITO) were prepared on 0.7 mm thick glass substrates using a pulsed laser deposition (PLD) process with average thickness of 150 nm. The samples were then exposed to high gamma γ radiation doses by {sup 60}Co radioisotope. The films have been irradiated by performing exposure cycles up to 250 kGy total doses at room temperature. The surface structures before and after irradiation were analysed by x-ray diffraction. Atomic Force Microscopy (AFM) was performed on all samples before and after irradiation to investigate any change in the grain sizes, and also in the roughness of the ITO surface. We investigated the influence of γ irradiation on the spectra of transmittance T, in the ultraviolet-visible-near infrared spectrum using spectrophotometer measurements. Energy band gap E{sub g} was then calculated from the optical spectra for all ITO films. It was found that the optical band gap values decreased as the radiation dose was increased. To compare the effect of the irradiation on refractive index n and extinction coefficient k properties, additional measurements were done on the ITO samples before and after gamma irradiation using an ellipsometer. The optical constants n and k increased by increasing the irradiation doses. Electrical properties such as resistivity and sheet resistance were measured using the four-point probe method. The good optical, electrical and morphological properties maintained by the ITO films even after being exposed to high gamma irradiation doses, made them very favourable to be used as anodes for solar cells and as protective coatings in space windows. - Highlights: • Indium Tin Oxide (ITO) thin films were deposited by pulsed laser deposition. • Effects of Gamma irradiation were investigated. • Changes of optical transmission and electrical properties of ITO films were studied. • Intensity of the diffraction peaks and the film's structure changed with increasing irradiation doses.

  4. From the Board of Editors: on Plagiarism

    Science.gov (United States)

    2005-05-01

    Dear Colleagues: There has been a significant increase in the number of duplicate submissions and plagiarism cases reported in all major journals, including the journals of the Optical Society of America. Duplicate submissions and plagiarism can take many forms, and all of them are violations of professional ethics, the copyright agreement that an author signs along with the submission of a paper, and OSA's published Author Guidelines. There must be a significant component of new science for a paper to be publishable. The copying of large segments of text from previously published or in-press papers with only minor cosmetic changes is not acceptable and can lead to the rejection of papers. Duplicate submission: Duplicate submission is the most common ethics violation encountered. Duplicate submission is the submission of substantially similar papers to more than one journal. There is a misperception in a small fraction of the scientific community that duplicate submission is acceptable because it sometimes takes a long time to get a paper reviewed and because one of the papers can be withdrawn at any time. This is a clear violation of professional ethics and of the copyright agreement that is signed on submission. Duplicate submission harms the whole community because editors and reviewers waste their time and in the process compound the time it takes to get a paper reviewed for all authors. In cases of duplicate submission, the Editor of the affected OSA journal will consult with the Editor of the other journal involved to determine the proper course of action. Often that action will be the rejection of both papers. Plagiarism: Plagiarism is a serious breach of ethics and is defined as the substantial replication, without attribution, of significant elements of another document already published by the same or other authors. Two types of plagiarism can occur-self-plagiarism and plagiarism from others' works. Self-plagiarism is the publication of substantially

    This work presents an optical fiber sensors based on lossy-mode resonance (LMR) phenomenon supported by indium tin oxide (ITO) thin overlay for investigation of electro-polymerization effect on ITO's surface. The ITO overlays were deposited on core of polymer-clad silica (PCS) fibers using reactive magnetron sputtering (RMS) method. Since ITO is electrically conductive and electrochemically active it can be used as a working electrode in 3-electrode cyclic voltammetry setup. For fixed potential applied to the electrode current flow decrease with time what corresponds to polymer layer formation on the ITO surface. Since LMR phenomenon depends on optical properties in proximity of the ITO surface, polymer layer formation can be monitored optically in real time. The electrodeposition process has been performed with Isatin which is a strong endogenous neurochemical regulator in humans as it is a metabolic derivative of adrenaline. It was found that optical detection of Isatin is possible in the proposed configuration.

    When Professor Anders Bárány took over as the Executive Editor of Physica Scripta, in 1986, he talked of his trepidation at having to 'dress himself' in his predecessor's 'editorial coveralls'. At that time, they had been worn by Professor Nils Robert Nilsson, a major figure in the physics community, for almost 20 years. Just one year prior to this, Professor Roger Wäppling had been recruited to the position of Subeditor in conjunction with a decision to expand the number of contributions in the field of condensed matter physics, to turn it into one of the dominant subjects in the broad-based journal. Physica Scripta had already gained a reputation for being a high quality journal with wide coverage of both experimental and theoretical physics. Interestingly, in the mid 1980s, the number of papers submitted had been growing and an impressive 250 submissions per year had been attained, with all of the manuscripts being handled in-house. Not many miles away in the town of Uppsala, a group of English students was stepping off a train on a magnificent snowy day in January to embark on their final year projects. A couple of us enjoyed ourselves so much that we stayed on afterwards as PhD students, thereby encountering the mixed pleasure of studying physics in a second language for the first time. I used to copy the notes down meticulously in Swedish, then try to work backwards with a textbook to improve my language skills. One day, returning from a particularly incomprehensible lecture on solid state physics, I showed my roommates my notes and asked if they could please explain what the lecture had been about: 'I don't know', they replied, 'but this bit is about sheep!' Meanwhile, back at Physica Scripta, the journal continued to flourish: 400 submissions were received in 1996, and the march of progress was well underway. Manuscripts could now be sent in on disks and Physica Scripta was available on the World Wide Web. Roger was appointed to manage the journal and

    The surface of Indium tin oxide (ITO) used as an electrode in organic light emitting diodes (OLEDs) and organic thin film transistors (OTFTs) was modified by a self-assembled monolayer (SAM). In order to increase the work function of the electrode, we modified the surface of the ITO by immersion in solutions including various SAM materials, such as 4-chlorophenhyl trichlorosilane (4-CPTS), chloromethyl trichlorosilane (CMTS), 4-chlorophenyl phosphonic acid (4-CPPA), 3-nitrophenyl phosphonic acid (3-NPPA) and 2-chloroethyl phosphonic acid (2-CEPA), at room temperature. The work function changes of the ITO with a SAM were measured by using a Kelvin probe. A work function increase of 1.09 eV was observed in the ITO with CMTS. In addition, it was found by using X-ray photoelectron spectroscopy that an increase in oxygen bonding energy contributed to the work function increase of the ITO. Through a SAM process, the transmittance of the ITO with a SAM was not changed. Therefore, some possibility of ohmic contact was shown because the energy barrier was removed in an interface between the ITO and an organic layer (pentacene or TPD) in the OTFT or the OLED. The origin of the work function increase of the ITO with a SAM was analyzed by X-ray photoelectron spectroscopy. These results suggest that ITO with a SAM greatly increases the probability for high-performance OLEDs and OTFTs.

    We have investigated the hybrid system constituted by the redox copper protein Azurin integrated with the semiconductor indium tin oxide (ITO) coated on quartz substrate. The system appears to be a good candidate for bio-sensing and bio-optoelectronics applications, especially due to the coupling between the optical and electron transfer features of Azurin with the conductive properties and optical transparency of ITO. The optical, morphological and electrical properties of the system have been investigated by combining optical absorption and transmission, steady-state fluorescence, resonance Raman spectroscopy and scanning probe microscopies. We found that Azurin molecules are firmly anchored on ITO and retain their structural and optical features underlying the physiological electron transfer activity. Scanning tunnelling spectroscopy evidenced a good electric coupling between the protein molecules and the substrate and a concomitant modulation of the ITO semiconductor properties upon deposition of Azurin. Some interplay between the conduction and valence bands of ITO and the electronic levels of Azurin is therefore suggested. These results are of a significant relevance in the perspective of developing bio-nanodevices able to process both optical and electrical signals, in conjugation also with the biorecognition capability of the protein molecules.

    Full Text Available A thin buffer layer of cadmium oxide (CdO was used to enhance the optical and electrical properties of indium tin oxide (ITO films prepared by an electron-beam evaporation technique. The effects of the thickness and heat treatment of the CdO layer on the structural, optical and electrical properties of ITO films were carried out. It was found that the CdO layer with a thickness of 25 nm results in an optimum transmittance of 70% in the visible region and an optimum resistivity of 5.1×10−3 Ω cm at room temperature. The effect of heat treatment on the CdO buffer layer with a thickness of 25 nm was considered to improve the optoelectronic properties of the formed ITO films. With increasing annealing temperature, the crystallinity of ITO films seemed to improve, enhancing some physical properties, such as film transmittance and conductivity. ITO films deposited onto a CdO buffer layer heated at 450 °C showed a maximum transmittance of 91% in the visible and near-infrared regions of the spectrum associated with the highest optical energy gap of 3.61 eV and electrical resistivity of 4.45×10−4 Ω cm at room temperature. Other optical parameters, such as refractive index, extinction coefficient, dielectric constant, dispersion energy, single effective oscillator energy, packing density and free carrier concentration, were also studied.

  11. Improved ITOS attitude control system with Hall generator brushless motor and earth-splitting technique

    The ITOS with an improved attitude control system is described. A Hall generator brushless dc torque motor will replace the brush dc torque motor on ITOS-I and ITOS-A (NOAA-1). The four attitude horizon sensors will be replaced with two CO2 sensors for better horizon definition. An earth horizon splitting technique will be used to keep the earth facing side of the satellite toward earth even if the desired circular orbit is not achieved. The external appearance of the pitch control subsystem differs from TIROS-M (ITOS-1) and ITOS-A (NOAA-1) in that two instead of one pitch control electronics (PCE) boxes are used. Two instead of four horizon sensors will be used and one instead of two mirrors will be used for sensor scanning. The brushless motor will eliminate the requirement for brushes, strain gages and the telemetry for the brush wear. A single rotating flywheel, supported by a single bearing provides the gyroscopic stability and the required momentum interchange to keep one side of the satellite facing the earth. Magnetic torquing against the earth's magnetic field eliminates the requirement for expendable propellants which would limit satellite life in orbit.

    The purpose of this study was to develop novel methods for attachment and cultivation of specifically positioned single yeast cells on a microelectrode surface with the application of a weak electrical potential. Saccharomyces cerevisiae diploid strains attached to an indium tin oxide/glass (ITO) electrode to which a negative potential between -0.2 and -0.4 V vs. Ag/AgCl was applied, while they did not adhere to a gallium-doped zinc oxide/glass electrode surface. The yeast cells attached to the negative potential-applied ITO electrodes showed normal cell proliferation. We found that the flocculin FLO10 gene-disrupted diploid BY4743 mutant strain (flo10Δ /flo10Δ) almost completely lost the ability to adhere to the negative potential-applied ITO electrode. Our results indicate that the mechanisms of diploid BY4743 S. cerevisiae adhesion involve interaction between the negative potential-applied ITO electrode and the Flo10 protein on the cell wall surface. A combination of micropatterning techniques of living single yeast cell on the ITO electrode and omics technologies holds potential of novel, highly parallelized, microchip-based single-cell analysis that will contribute to new screening concepts and applications. © FEMS 2015.

    Tin doped Indium Oxide (ITO) is a wide band gap semiconductor with high conductivity and transparency in the visible region of the solar spectrum. One of the most popular and exploited applications of ITO is the realization of the transparent conductive layers needed for the electrodes of light sensitive devices, such as photovoltaic cells. The thermal energy for the crystallization of ITO films is very low (150°C). The crystallization can be achieved by the continuous energetic bombardment of the ions in the sputtering chamber without annealing or substrate heating. The accumulated energy will ensure the thermal energy necessary for the crystallization. With the help of sufficiently high sputtering power and sufficient duration, crystallized ITO films can be produced without annealing. In this report, a comparison of the conductivity and transparency of ITO films under two crystallization conditions ((1) crystallization of the sputtered films by annealing; (2) in situ crystallization of the films by providing high sputtering power and long sputtering duration) will be presented.

    In this work, development of semi-transparent electrodes for efficient large area organic solar cells (OSCs) has been demonstrated. Electron beam evaporated silver grids were embedded in commercially available ITO coatings on glass, through a standard negative photolithography process, in order to improve the conductivity of planar ITO substrates. The fabricated electrodes with embedded line and square patterned Ag grids reduced the sheet resistance of ITO by 25% and 40%, respectively, showing optical transmittance drops of less than 6% within the complete visible light spectrum for both patterns. Solution processed bulk heterojunction OSCs based on PTB7:[70]PCBM were fabricated on top of these electrodes with cell areas of 4.38 cm2, and the performance of these OSCs was compared to reference cells fabricated on pure ITO electrodes. The Fill Factor (FF) of the large-scale OSCs fabricated on ITO with embedded Ag grids was enhanced by 18% for the line grids pattern and 30% for the square grids pattern compared to that of the reference OSCs. The increase in the FF was directly correlated to the decrease in the series resistance of the OSCs. The maximum power conversion efficiency (PCE) of the OSCs was measured to be 4.34%, which is 23% higher than the PCE of the reference OSCs. As the presented method does not involve high temperature processing, it could be considered a general approach for development of large area organic electronics on solvent resistant, flexible substrates.

    ‘I want the journal to acquire a reputation for very rapid, fair, and accurate reviewing,’ asserted John F. Dewey, editor-in-chief of AGU's newest journal, Tectonics. Dewey said that he will rule the bimonthly, which will begin publication in February, ‘with a bit of a rod of iron’ to ensure that Tectonics is ‘where only original and important papers are published.’‘I'm going to be very strict with reviewers,’ Dewey explained in his quick British clip. ‘If the review does not come back to me within 10 days to 2 weeks, I'll review the paper myself. I'm also going to have a system whereby, if a paper needs major surgery after being refereed, it will be rejected. Papers will have to be in virtually publishable condition before they are first submitted,’ he said.

    Full Text Available The Editorial Board of the journal Thermal Science is continuing to pay great attention to the processes in internal combustion engines, both due to their environmental impact and ability to use renewable energy sources i. e. different types of biofuels. Concerning that motor vehicles contribute about 14% of the global CO2 emission, it is understandable that many research efforts are devoted to processes in internal combustion engines and use of biofuels. The number of submitted papers dealing with processes in internal combustion engines is growing from months to months, so in the journal Thermal Science also will published in 2011 one issue devoted to the same topics. Papers submitted are already in the reviewing process. Professor Dragoslava Stojiljkovi} and Professor Stojan Petrovi} as Guest editors, had again a difficult task to make appropriate choice of the papers, covering wide range of topics. I am very grateful to Guest editors for their extremely competent choice of the topics and papers. Reviewers of the papers made, also, tremendous contributions to the quality of the papers published. This time, also, as in No. 3, 2009, we asked experts in traffic engineering to give their contribution. They pointed out importance of the internal combustion engine energy efficiency, vehicle fleet operation management and logistic efficiency, and painted large scale picture of the environmental problems caused by large density traffic. We hope that this point of view will make new impulse for many new joint projects with the aim to investigate impact of the processes in internal combustion engines and logistic of motor fleet management, and organization of traffic flows, especially in large towns, on environment. Papers devoted to the thermal processes in internal combustion engines are grouped in Part one of this issue. Due to large number of papers accepted for publication, we have been forced to introduce Part two, in which are grouped selected

    2017-09-01

    Transparent Conductive Oxide (TCO) layers due to transparency, high conductivity and hole injection capability have attracted a lot of attention. One of these layers is Indium Tin Oxide (ITO). ITO due to low resistance, transparency in the visible spectrum and its proper work function is widely used in the manufacture of organic light emitting diodes and solar cells. One way for improving the ITO surface is plasma treatment. In this paper, changes in surface morphology, by applying argon atmospheric pressure cold plasma, was studied through Atomic Force Microscopic (AFM) image analysis and Fourier Transform Infrared Spectroscopy (FTIR) analysis. FTIR analysis showed functional groups were not added or removed, but chemical bond angle and bonds strength on the surface were changed and also AFM images showed that surface roughness was increased. These factors lead to the production of diodes with enhanced Ohmic contact and injection mechanism which are more appropriate in industrial applications.

    We demonstrate a highly sensitive and flexible bending strain sensor using tin-doped indium oxide (ITO) nanoparticles (NPs) assembled in line patterns on flexible substrates. By utilizing transparent ITO NPs without any surface modifications, we could produce strain sensors with adjustable gauge factors and optical transparency. We were able to control the dimensional and electrical properties of the sensors, such as channel height and resistance, by controlling the NP assembly speed. Furthermore, we were able to generate controlled gauge factor with values ranging from 18 to 157, which are higher than previous cases using metallic Cr NPs and Au NPs. The alignment of the ITO NPs in parallel lines resulted in low crosstalk between the transverse and longitudinal bending directions. Finally, our sensor showed high optical transmittance, up to ∼93% at 500 nm wavelength, which is desirable for flexible electronic applications.

    There is considerable gender disparity in editorial boards of medical journals. Being an editor in a Cochrane review group (CRG), like being an editor in a medical journal, is an indirect representation of one's reputation and leadership abilities in a particular specialty. The aim of the study was to analyze the representation of women editors on the editorial teams of CRG's and the Central Editorial Unit (CEU) of the Cochrane Collaboration. Information about editorial team members of CRGs and the CEU was extracted from respective websites. Gender of the individual was determined by inspection of names, individual profile description or photographs in the CRG or institutional webpage, social networking sites and internet search. Data was validated by two authors independently and differences sorted by consensus. A total of 788 editors across all CRGs and the CEU with an overall 371 females (47.1%) and 417 (52.9%) males were identified. of the CEU editors, 62.5% were females. There were 68 coordinating editors (35.3% females), and 62 managing editors (56% females), who provided leadership to the CRGs. Eighty-four percent of trial search coordinators were found to be females. Ten CRGs had 75% or more of its editors as females while 7 CRGs had less than or equal to 25% female editors. The representation of women editors in the Cochrane Collaboration was found to be better than in editorial boards of medical journals. There is still scope for improvement to ensure better gender diversity across all roles and in all CRG's. © 2014 Chinese Cochrane Center, West China Hospital of Sichuan University and Wiley Publishing Asia Pty Ltd.

  13. JSME: a free molecule editor in JavaScript.

    2013-01-01

    A molecule editor, i.e. a program facilitating graphical input and interactive editing of molecules, is an indispensable part of every cheminformatics or molecular processing system. Today, when a web browser has become the universal scientific user interface, a tool to edit molecules directly within the web browser is essential. One of the most popular tools for molecular structure input on the web is the JME applet. Since its release nearly 15 years ago, however the web environment has changed and Java applets are facing increasing implementation hurdles due to their maintenance and support requirements, as well as security issues. This prompted us to update the JME editor and port it to a modern Internet programming language - JavaScript. The actual molecule editing Java code of the JME editor was translated into JavaScript with help of the Google Web Toolkit compiler and a custom library that emulates a subset of the GUI features of the Java runtime environment. In this process, the editor was enhanced by additional functionalities including a substituent menu, copy/paste, drag and drop and undo/redo capabilities and an integrated help. In addition to desktop computers, the editor supports molecule editing on touch devices, including iPhone, iPad and Android phones and tablets. In analogy to JME the new editor is named JSME. This new molecule editor is compact, easy to use and easy to incorporate into web pages. A free molecule editor written in JavaScript was developed and is released under the terms of permissive BSD license. The editor is compatible with JME, has practically the same user interface as well as the web application programming interface. The JSME editor is available for download from the project web page http://peter-ertl.com/jsme/

    Full Text Available Indium tin oxide (ITO thin films have been prepared using the reactive evaporation technique on glass substrates in an oxygen atmosphere. It is found that the deposition rate plays prominent role in controlling the electrical and optical properties of the ITO thin films. Resistivity, electrical conductivity, activation energy, optical transmission and band gap energy were investigated. A transmittance value of more than 90% in the visible region of the spectrum and an electrical conductivity of 3x10–6 Ωm has been obtained with a deposition rate of 2 nm/min. XRD studies showed that the films are polycrystalline.

    In this paper, an indium-tin oxide (ITO) thin-film patterning method for higher pattern quality and productivity compared to the short-pulsed laser direct writing method is presented. We sputtered a thin ITO layer on a glass substrate, and then, plated a thin gold layer onto the ITO layer. The combined structure of the three layers (glass-ITO-gold) was patterned using laser-induced plasma generated by an ytterbium pulsed fiber laser (λ = 1064 nm). The results showed that the process parameters of 50 mm/s in scanning speed, 14 ns pulse duration, and a repetition rate of 7.5 kHz represented optimum conditions for the fabrication of ITO channels. Under these conditions, a channel 23.4 μm wide and 20 nm deep was obtained. However, built-up spikes (∼15 nm in height) resulted in a decrease in channel quality, and consequently, short circuit occurred at some patterned positions. These built-up spikes were completely removed by dipping the ITO layer into an etchant (18 wt.% HCl). A gold masking layer on the ITO surface was found to increase the channel surface quality without any decrease in ITO thickness. Moreover, the effects of repetition rate, scanning speed, and etching characteristics on surface quality were investigated.

    Indium is a scarce and expensive material that has been identified as a bottleneck for future organic electronics deployment in large scale. Indium is the main constituent of Indium Tin Oxide (ITO), which is the most successful transparent electrode in organic photovoltaics (OPV) so far. A new...... process, termed Hiflex, allows for manufacture of flexible OPV modules where the ITO electrode has been replaced by a sputtered Al/Cr electrode in an inverted device architecture with front illumination. This work presents a life cycle assessment of the Hiflex process, in order to compare...... the environmental impact of avoiding ITO as electrode. The new ITO-free process reduces some of the processing steps, leading to important reductions of the energy input during OPV module manufacturing in comparison to ITO-based modules. The environmental analysis reveals an Energy Pay-Back time (EPBT) of 10 years...

  20. Towards the implementation of a system for manuscript editor certification

    Full Text Available Style and format are important criteria for evaluating a journal and indexing it in major databases. In Korean science, technology, and medical journals, interest in manuscript editing has increased over the past seven to eight years, and the responsibilities of manuscript editors have expanded as well. However, since no clear standards for the roles and qualifications for manuscript editors are yet available, a formal certification system is needed to establish appropriate standards and to provide professional training. To identify ways of developing a manuscript editor certification program in Korea, this study investigated similar certification programs in and outside the country and surveyed 195 Korean editors, manuscript editors, publishers, and medical librarians. The survey revealed that manuscript editors were necessary (mean score of 4.38 on a five-point Likert scale, with a score of 5 indicating strong agreement, and that their main contributions were efficiently managing the editorial board, improving the accuracy of references, and accelerating the editing process. The respondents were also positive about the possibility of implementing a manuscript editor certification; 45.1% showed interest in becoming certified, and 47.1% reported interest in hiring a certified manuscript editor. Regarding the system for issuing certification, respondents favored a professional training course (53.1%, validation of work experience (27.1%, or an examination (16.8%. This study concludes that it is essential to establish a formal certification program to train manuscript editors properly, and an examination system is the most efficient and suitable method for managing the certification process.

    The effect of thermal annealing on the electrical and optical characteristics of ITO films prepared by reactive sputtering and thermal evaporation have been studied. The effect of the thermal annealing is to improve the conductivity and the optical transmission in the shorter wavelength region. The conductivity of the films increases with annealing temperature, this behaviour is associated with grain growth in the film. (author)

    Highlights: • The localized surface plasmon resonance of silver thin film was generated by ITO buffer layer. • The tunability of surface plasmon resonance wavelength was realized by varying silver thin film thickness. • Raman scattering intensity varies with silver layer thickness. • FDTD calculation results of electronic field distribution are consistent with those of experiments. - Abstract: A series of silver films with various thicknesses were deposited on ITO covered silica substrates by magnetron sputtering at room temperature. The tunability of the surface plasmon resonance wavelength was realized by varying the thickness of silver thin film. By adjusting the silver layer thickness from 5 to 40 nm, the resonance wavelength shows a blueshift, which is due to a change in the electromagnetic field coupling strength from the localized surface plasmons excited between the silver thin film and ITO layer. In contrast, when the ITO layer is absent from the system, no noticeable shift in the resonance wavelength is observed upon varying the silver thin film thickness.

  10. 3D Si/ITO/WO3 photoelectrode with a micropost array structure for photocatalysis enhancement

    In this paper, a three-dimensional (3D) tandem Si/ITO/WO3 photoelectrode system with a high-aspect-ratio (HAR) micropost array structure based on a ‘Z-scheme’ is designed to enhance photocatalytic performance. To produce such a photoelectrode system, microposts were first fabricated on a Si substrate by deep reactive ion etching (DRIE), followed by deposition of an indium tin oxide (ITO) layer and tungsten trioxide (WO3) layer on microposts. The photocatalytic performance was verified by the degradation of methylene blue (MB, C16H18ClN3S) under visible light conditions. In the photocatalytic test, photoelectrode samples of a 0.5 cm2 footprint were used to degrade 15 ml MB (10 mg l‑1). Experimental results indicate that the 3D micropost WO3/ITO/Si structure has a higher efficiency compared with the 2D planar WO3/ITO/Si structure. A decrease of 83.6% in MB concentration within 30 min is observed in the preliminary degradation test. The HAR photoelectrode configuration can dramatically increase the surface-to-volume ratio, not only increasing the total incident light absorption efficiency, but also facilitating the oxidation–reduction reaction in the semiconductor-liquid interface.

    ESDAPT is a graphical programming environment for developing APT (Automatically Programmed Tool) programs for controlling numerically controlled machine tools. ESDAPT has a graphical user interface that provides the user with an APT syntax sensitive text editor and windows for displaying geometry and tool paths. APT geometry statement can also be created using menus and screen picks. ESDAPT interprets APT geometry statements and displays the results in its view windows. Tool paths are generated by batching the APT source to an APT processor (COSMIC P-APT recommended). The tool paths are then displayed in the view windows. Hardcopy output of the view windows is in color PostScript format. ESDAPT is written in C-language, yacc, lex, and XView for use on Sun4 series computers running SunOS. ESDAPT requires 4Mb of disk space, 7Mb of RAM, and MIT's X Window System, Version 11 Release 4, or OpenWindows version 3 for execution. Program documentation in PostScript format and an executable for OpenWindows version 3 are provided on the distribution media. The standard distribution medium for ESDAPT is a .25 inch streaming magnetic tape cartridge (Sun QIC-24) in UNIX tar format. This program was developed in 1992.

    Full Text Available Calvino editor. Reflections on Calvino’s paratextsSeveral Italian writers and men of letters have contributed directly to the organization of publishing companies during the twentieth century. To this group belongs Italo Calvino, who entertained a long working relationship with the publishing house Einaudi, lasting nearly forty years. This professional experience, strictly interwoven with Calvino’s activity as a novelist, gave the writer the opportunity to promote his idea of literature, the same idea that permeates his fiction. Calvino was not only engaged in the choice of the books to be published, but also in the writing of the introductions and back covers that often took, because of their complexity, the character of short critical essays. Through his prefaces the writer established a long-distance dialogue with readers, tendering them not solely promotional reviews, but rather his own narratological reflections. Multiple levels of discourse − analytical, critical, and narrative − converge therefore in the introductory writings of Calvino, unused to the impersonal language or blandishments of the traditional publishing. Furthermore, compared to the books of other writers, the forewords prepared for his own books are more complex and frequently subject to constant changes of mind, hesitations and vacillations. In any case Calvino’s paratexts constitute an important key to approach his poetics and, more generally, large areas of the Italian literature after the Second World War.

  18. EDITORIAL: Incoming Editor-in-Chief

    Science.gov (United States)

    2006-01-01

    Physics in Medicine and Biology (PMB) is a journal that originated in the UK but is now rightly regarded as one of the pre-eminent international journals for the publication of material coming within its remit. It is 50 years old and its maturity is an outcome of the consistent support of high performing authors, a supportive and professional publishing house, dedicated referees, many vigorous and conscientious editorial boards and the collective input of the 10 previous Editors as listed in his incoming editorial (January 2000 issue) by the retiring Editor, Professor Alun Beddoe. The scientific climate and it associated publication modus operandi in the 1950s was very different from that at the current time and the journal has evolved to reflect this. Hence today the scope of content is somewhat broader, the size of the journal is vastly greater, the whole publication process is slicker and more efficient and a paper in PMB is highly prized by its authors and those who look to quality factors and impact. The quality of the journal still relies on the voluntary labour and expertise of its busy international referees and Board members. For many years I have tried to place my own research material in PMB and encourage my teams to do likewise, not only acknowledging the prestige of the journal but also because of the extraordinarily fast turnaround time of all the processes without any loss of quality. This serves us very well and the publishing team are to be congratulated. Some things seem to change more slowly or not at all, however. The prediction, when I started my research career, that books and journals would be dinosaurs by now has manifestly not come true and, whilst most of us are addicted (and why not?) to the electronic ways of doing things that can be done by more traditional ways, PMB and a packet of reprints from time to time arriving by post still has a reassuring feel despite the fact that the papers have been `on-line' for a while before.

    With greater optical penetration depth and lower ablation threshold fluence, it is difficult to directly fabricate large scales of laser-induced periodic surface structures (LIPSSs) on indium-tin-oxide (ITO) films. This study proposed an approach to obtain optimized LIPSSs by sputtering an Au thin film on the ITO film surface. The concept behind the proposal is that the upper layer of the thin Au film can cause surface energy aggregation, inducing the initial ripple structures. The ripples deepened and become clear with lower energy due to optical trapping. The effective mechanism of Au film was analyzed and verified by a series of experiments. Linear sweep, parallel to the laser polarization direction, was performed using a Nd:VAN laser system with 10-ps Q-switched pulse, at a central wavelength of 532 nm, with a repetition rate of 1 kHz. The complete and clear features of the nanostructures, obtained with the periods of approximately 320 nm, were observed on ITO films with proper laser fluence and scanning speed. The depth of ripples was varying in the range of 15-65 nm with clear and coherent ITO films. The preferred efficiency of fabricating nanostructures and the excellent results were obtained at a scanning speed of 2.5 mm/s and a fluence of 0.189 J/cm2. In this way, the ablation and shedding of ITO films was successfully avoided. Thus, the proposed technique can be considered to be a promising method for the laser machining of special nonmetal films.

    The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship - emphasizing the importance of responsibility and accountability - have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors' Network of the European Society of Cardiology.

    The collection, management and visualisation of clinical pedigree (family history) data is a core activity in clinical genetics centres. However, clinical pedigree datasets can be difficult to manage, as they are time consuming to capture, and can be difficult to build, manipulate and visualise graphically. Several standalone graphical pedigree editors and drawing applications exist but there are no freely available lightweight graphical pedigree editors that can be easily configured and incorporated into web applications. We developed 'pedigreejs', an interactive graphical pedigree editor written in JavaScript, which uses standard pedigree nomenclature. Pedigreejs provides an easily configurable, extensible and lightweight pedigree editor. It makes use of an open-source Javascript library to define a hierarchical layout and to produce images in scalable vector graphics (SVG) format that can be viewed and edited in web browsers. The software is freely available under GPL licence (https://ccge-boadicea.github.io/pedigreejs/). tjc29@cam.ac.uk.

    The American Psychologist is the official journal of the American Psychological Association. As such, it is a valued outlet for articles dealing with reviews of current topics in psychology, policy issues, and critiques of current research. S. O. Lilienfeld submitted a manuscript to the journal that was accepted by the ad hoc action editor; however, the action editor's decision was later overruled by the editor, and additional changes to the manuscript were requested. Because of this editorial decision, a controversy arose that played out on various Internet discussion groups. The author presents his perspective as the editor in this controversy. Points of emphasis include the need to protect the integrity and the confidentiality of the peer review process for scientific journals.

    This document is composed of a poster and its abstract. The long Wendelstein 7-X experiment programs will be segmented into arbitrary time slices. For each of these segments the planned behaviour is stored in a configuration database - and that for every component within the W7X hierarchical layout. Up to now we have an editor to set up these segments for each single component. But generating the compound program description out of the components' segments is still time-consuming experts' hand work. It is planned to implement a top-down program editor which is able to break down a high level physics program proposal to component segments while observing all the physical and technical constraints - a quite ambitious intention. This poster describes the first step to an experiment program editor: The 'express program editor' will be able to modify parameters of a single, a subset, or all segments within a given program, thus adapting its behaviour in an easy way. A graphical program structure overview has been implemented giving fast access to program parameters for comparison and editing. Appropriate parameter editors regard type and constraints as known from the single-segment editor. In a single transaction all changes are saved, the resulting experiment program is re-generated and the involved components are triggered to reload the changed program. Even though changing the program's structure is not supported in this version, the express program editor will serve as a tool for quick program adaptations in the daily experiment routine. Furthermore this implementation will be used as a design and usage study for the later high-end W7-X program editor. (authors)

    1994-01-01

    The ZED editor for the DEC VAX is a simple, yet powerful line editor for text, program source code, and non-binary data. Line editors can be superior to screen editors in some cases, such as executing complex multiple or conditional commands, or editing via slow modem lines. ZED excels in the area of text processing by using procedure files. For example, such procedures can reformat a file of addresses or remove all comment lines from a FORTRAN program. In addition to command files, ZED also features versatile search qualifiers, global changes, conditionals, on-line help, hexadecimal mode, space compression, looping, logical combinations of search strings, journaling, visible control characters, and automatic detabbing. The ZED editor was originally developed at Cambridge University in London and has been continuously enhanced since 1976. Users of the Cambridge implementation have devised such elaborate ZED procedures as chess games, calculators, and programs for evaluating Pi. This implementation of ZED strives to maintain the characteristics of the Cambridge editor. A complete ZED manual is included on the tape. ZED is written entirely in C for either batch or interactive execution on the DEC VAX under VMS 4.X and requires 80,896 bytes of memory. This program was released in 1988 and updated in 1989.

    2017-01-01

    Tin doped indium oxide (ITO) thin films are being used extensively as transparent conductors in several applications. In the present communication, we report the electrical transport in DC magnetron sputtered ITO thin films (prepared at 300 K and subsequently annealed at 673 K in vacuum for 60 minutes) in low temperatures (25-300 K). The low temperature Hall effect and resistivity measurements reveal that the ITO thin films are moderately dis-ordered (kFl˜1; kF is the Fermi wave vector and l is the electron mean free path) and degenerate semiconductors. The transport of charge carriers (electrons) in these disordered ITO thin films takes place via the de-localized states. The disorder effects lead to the well-known `metal-insulator transition' (MIT) which is observed at 110 K in these ITO thin films. The MIT in ITO thin films is explained by the quantum correction to the conductivity (QCC); this approach is based on the inclusion of quantum-mechanical interference effects in Boltzmann's expression of the conductivity of the disordered systems. The insulating behaviour observed in ITO thin films below the MIT temperature is attributed to the combined effect of the weak localization and the electron-electron interactions.

The dependence of cathode performance and durability on the ITO content and the diameter of the CNTs were investigated by electrochemical techniques. The cathode with 30 wt% ITO and CNTs with diameters 10–20 nm in the composite offered preferred locations for Pt stabilization and was very resistant to carbon corrosion (i.e., 82.7% ESA retention and 105.7% mass activity retention after an accelerated stress test for 400 h).

MST is well known across research communities worldwide as a leading journal in which to publish new techniques and instrumentation. It has gained this enviable position largely because of the excellent guidance of its Editorial Board and dedicated staff at Institute of Physics Publishing over many years. I want to highlight in particular the contribution of the outgoing Editor Peter Hauptmann, and other Editors before him, in making the journal truly international. We thank Peter immensely for all his hard work in leading the journal, having exceptionally served two terms, each of five years. I come into the post of Editor at a very interesting and challenging time for research. The global recession is leading to cuts in research funding in many countries, researchers and their outputs are coming under closer scrutiny than ever before, and more is being expected of them. Journals play a critical role in monitoring and maintaining research standards, but we should be careful not to assume that journal Impact Factor is the sole measure of research quality. Although expediency may sometimes demand it, Impact Factor, as practitioners know, is subject dependent. One of the great things about science and technology for me is its level playing field. The key point is still innovation no matter where the work is done or where it is published. MST has a long pedigree of being the natural home of the highest quality papers from leading researchers wishing to report novel instrumentation and techniques. 2013 will mark the 90th anniversary of MST and we look forward to celebrating in style its sustained success. I recall with pride the first paper I published in Journal of Physics E: Scientific Instruments (as MST was previously titled) back in 1977. The paper reported the design and application of an early fluorescence lifetime spectrometer that I had constructed

    We report reversible bipolar resistance switching behaviors in transparent indium-tin oxide (ITO)/LaAlO3/SrTiO3 memristors at room temperature. The memristors exhibit high optical transparency, long retention, and excellent antifatigue characteristics. The high performances are promising for employing ITO/LaAlO3/SrTiO3 memristors in nonvolatile transparent memory and logic devices. The nonvolatile resistance switching behaviors could be attributed to the migration of positively charged oxygen vacancies from the SrTiO3 substrate to the LaAlO3 film, resulting in Poole-Frenkel emission for the low resistance state and thermionic emission for the high resistance state.

    This study discusses the influence of working pressure on the surface energy of the ITO thin films produced by radio frequency magnetron sputtering method. Optical tensiometer (Attension Theta Lite) is used for evaluating wetting behavior of the water droplet on the film surface and Equation of State method was selected to determine surface free energy for this study. Equation of state method does not divide the surface tension into different components such as polar, dispersive, acid-base. It is calculated the surfaces’ free energy measuring the contact angle with a single liquid. The surface free energy value was in the range of 15-31 mN/m. Also, the transmittances were determined in the wavelength range between 200 and 1000 nm using the UNICO 4802 UV-Vis double beam spectrophotometer. Transmittances of the produced ITO thin films are greater than %70 in the visible range.

    Thin films of aluminium-doped zinc oxide (AZO) and indium tin oxide (ITO) were deposited on glass substrates by laser ablation in an oxygen environment. The electrical and optical properties of films grown at various oxygen pressures were compared. With no substrate heating, highly transparent...... and conducting films were obtained with oxygen pressures between 15 and 23 mTorr for both materials. We obtained a specific resistivity of 1.8 x 10(-3) Omega cm for AZO and 1.1 x 10(-3) Omega cm for ITO. By heating the substrate to 160 degrees C or 200 degrees C, the resistivity was further reduced to 1.1 x 10...

    We develop a calculus for functionals of integer-valued measures, which extends the Functional It\\^o calculus to functionals of Poisson random measures in a pathwise sense. We show that smooth functionals in the sense of this pathwise calculus are dense in the space of square-integrable (compensated) integrals with respect to a large class of integer-valued random measures. As a consequence, we obtain an explicit martingale representation formula for all square-integrable martingales with res...

  20. Understanding the mechanisms that change the conductivity of damaged ITO-coated polymeric films: A micro-mechanical investigation

    KAUST Repository

    Nasr Saleh, Mohamed

    2014-11-01

    Degradation from mechanical loading of transparent electrodes made of indium tin oxide (ITO) endangers the integrity of any material based on these electrodes, including flexible organic solar cells. However, how different schemes of degradation change the conductivity of ITO devices remains unclear. We propose a systematic micro-mechanics-based approach to clarify the relationship between degradation and changes in electrical resistance. By comparing experimentally measured channel crack densities to changes in electrical resistance returned by the different micro-mechanical schemes, we highlight the key role played by the residual conductivity in the interface between the ITO electrode and its substrate after delamination. We demonstrate that channel cracking alone does not explain the experimental observations. Our results indicate that delamination has to take place between the ITO electrode and the substrate layers and that the residual conductivity of this delaminated interface plays a major role in changes in electrical resistance of the degraded device. © 2014 Elsevier B.V.

    This investigation reports on the characteristics of MAPbI3 perovskite films on obliquely sputtered ITO/glass substrates that are fabricated with various sputtering times and sputtering angles. The grain size of a MAPbI3 perovskite film increases with the oblique sputtering angle of ITO thin films from 0° to 80°, indicating that the surface properties of the ITO affect the wettability of the PEDOT:PSS thin film and thereby dominates the number of perovskite nucleation sites. The optimal power conversion efficiency (Eff) is achieved 11.3% in a cell with an oblique ITO layer that was prepared using a sputtering angle of 30° for a sputtering time of 15 min.

  3. In Situ Synthesis and Deposition of Gold Nanoparticles with Different Morphologies on Glass and ITO Substrate by Ultrasonic Spray Pyrolysis

    Full Text Available Gold nanoparticles were synthesized and deposited in situ by ultrasonic spray pyrolysis on glass and indium tin oxide (ITO substrates. This technique led to the formation of gold nanoparticles with different morphologies without the use of any capping agent. The gold nanoparticles deposited on glass substrate were obtained as nanospheres with an average particle size of 30 nm with some agglomerates; however, the nanoparticles deposited on ITO substrate were obtained with different morphologies, such as triangular nanoprisms, nanorods, nanocubes, and nanorhombus, with particle sizes between 40 and 100 nm. The ITO substrate influenced the morphology of the gold nanoparticles obtained due to changes in the deposition temperature, which also change the crystalline structure of the ITO film on the substrate.

    Transparent and conductive Zn-In-Sn-O (ZITO) amorphous thin films have been deposited at room temperature by the rf magnetron co-sputtering of ITO and ZnO targets. Co-sputtering gives the possibility to deposit multicomponent oxide thin films with different compositions by varying the power to one of the targets. In order to make ZITO films with different Zn content, a constant rf power of 50 W was used for the ITO target, where as the rf power to ZnO target was varied from 25 W to 150 W. The as deposited films showed an increase in Zn content ratio from 17 to 67% as the power to ZnO target was increased from 25 to 150 W. The structural, electrical and optical properties of the as deposited films are reported. The films showed an average transmittance over 80% in the visible wavelength range. The electrical resistivity and optical band gap of the ZITO films were found to depend on the Zn content in the film. The ZITO films deposited at room temperature with lower Zn content ratios showed better optical transmission and electrical properties compared to ITO film.

    Radio frequency (RF) biasing induced by a second plasma source at the substrate is applied to low-temperature sputtering processes for indium tin oxide (ITO) and titanium nitride (TiN) thin films. Investigations on crystal structure and surface morphology show that RF-biased substrate plasma processes result in a changed growth regime with different grain sizes and orientations than those produced by processes without a substrate bias. The influence of the RF bias is shown comparatively for reactive RF-sputtered ITO and reactive direct-current-sputtered TiN. The ITO layers exhibit an improved electrical resistivity of 0.5 mΩ cm and an optical absorption coefficient of 0.5 × 10{sup 4 }cm{sup −1} without substrate heating. Room-temperature sputtered TiN layers are deposited that possess a resistivity (0.1 mΩ cm) of 3 orders of magnitude lower than, and a density (5.4 g/cm{sup 3}) up to 45% greater than, those obtained from layers grown using the standard process without a substrate plasma.

Silver nanoparticles with an average diameter of {approx}40 nm supported on indium tin oxide (ITO) were irradiated with a tightly focused pulsed laser (doubled frequency beam) at 532 nm. The size transformation of silver nanoparticles induced by a single pulse of Nd:YAG laser ({lambda} = 532 nm, pulse width = 30 ps) was directly observed by an electron scanning microscopy (FE-SEM) on indium tin oxide surface. Simultaneously the change in the absorption and the corresponding derivatives are also presented. These morphological changes are accompanied by a significant change in the optical absorption properties of the array. This study demonstrates that picosecond laser irradiation is an excellent technique to operate and control the properties of nanostructured materials on solid supports.

    For more than 130 years, the hepatic stellate cells (also known as Ito cells) have been the object of numerous studies that aimed at their characterization both in normal and postlesional status, where they play a key role in fibrosis progression specific for chronic hepatic pathology. Converged studies on their histophysiology have revealed other functions, namely the involvement in liver embryological development and regeneration, metabolisms regulation, modulation of local inflammatory and immune reactions. Ito cells plasticity is surprising, as they are able to provide the connection between the complex sinusoidal and parenchymal microenvironment, influencing by autocrine and paracrine mechanisms the extracellular matrix content in tight correlation to growth and repair necessities. Last but not least, Ito cells take an active part in systemic homeostasis maintenance by their capacity to store and mobilize vitamin A, respectively. The evolving interest in their research will be undoubtedly followed by a better knowledge of the physiopathological sequences responsible for liver diseases, as new targets for the development of new therapeutic approaches directed toward improvement of prognosis and patients' quality of life.

    In this study, indium-tin-oxide (ITO) nanoparticles were simply recovered from the thin film transistor-liquid crystal display (TFT-LCD) panel scraps by means of lift-off method. This can be done by dissolving color filter (CF) layer which is located between ITO layer and glass substrate. In this way the ITO layer was easily lifted off the glass substrate of the panel scrap without panel crushing. Over 90% of the ITO on the TFT-LCD panel was recovered by using this method. After separating, the ITO was obtained as particle form and their characteristics were investigated. The recovered product appeared as aggregates of particles less than 100 nm in size. The weight ratio of In/Sn is very close to 91/9. XRD analysis showed that the ITO nanoparticles have well crystallized structures with (222) preferred orientation even after recovery. The method described in this paper could be applied to the industrial recovery business for large size LCD scraps from TV easily without crushing the glass substrate.

    Conductive and highly transparent indium tin oxide (ITO) thin films were prepared on photosensitive glass substrates by the combination of sol-gel and spin-coating techniques. First, the substrates were coated with amorphous Sn-doped indium hydroxide, and these amorphous films were then calcined at 550 {sup circle} C to produce crystalline and electrically conductive ITO layers. The resulting thin films were characterized by means of scanning electron microscopy, UV-Vis spectroscopy, X-ray photoelectron spectroscopy and spectroscopic ellipsometry. The measurements revealed that the ITO films were composed of spherical crystallites around 20 nm in size with mainly cubic crystal structure. The ITO films acted as antireflection coatings increasing the transparency of the coated substrates compared to that of the bare supports. The developed ITO films with a thickness of {proportional_to}170-330 nm were highly transparent in the visible spectrum with sheet resistances of 4.0-13.7 k{omega}/sq. By coating photosensitive glass with ITO films, our results open up new perspectives in micro- and nano-technology, for example in fabricating conductive and highly transparent 3D microreactors.

    Full Text Available The behavior of bi- and trilayer coating systems for flexible a-Si:H based solar cells consisting of a barrier, an electrode, and an absorption layer is studied under mechanical load. First, the film morphology, stress, Young’s modulus, and crack onset strain (COS were analyzed for single film coatings of various thickness on polyethylene terephthalate (PET substrates. In order to demonstrate the role of the microstructure of a single film on the mechanical behavior of the whole multilayer coating, two sets of InSnOx (indium tin oxide, ITO conductive coatings were prepared. Whereas a characteristic grain–subgrain structure was observed in ITO-1 films, grain growth was suppressed in ITO-2 films. ITO-1 bilayer coatings showed two-step failure under tensile load with cracks propagating along the ITO-1/a-Si:H-interface, whereas channeling cracks in comparable bi- and trilayers based on amorphous ITO-2 run through all constituent layers. A two-step failure is preferable from an application point of view, as it may lead to only a degradation of the performance instead of the ultimate failure of the device. Hence, the results demonstrate the importance of a fine-tuning of film microstructure not only for excellent electrical properties, but also for a high mechanical performance of flexible devices (e.g., a-Si:H based solar cells during fabrication in a roll-to-roll process or under service.

    Sn-doped In{sub 2}O{sub 3} (ITO) thin films were deposited on a glass substrate with reactive RF magnetron sputtering and then post-deposition electro-annealed. The electron accelerating voltage was varied from 300 to 900 V, and the substrate temperature was increased to 250 C with an electron accelerating voltage of 900 V for 20 min in a 4 x 10{sup -1} Pa vacuum. As-deposited and ITO films electro-annealed at low energy ({<=}600 eV) were found to be in the amorphous phase, while ITO films electro-annealed at 900 eV showed diffraction peaks of the ITO (222) and (400) planes. As the electron accelerating voltage increased, the electrical resistivity decreased to as low as 6 x 10{sup -4} {omega}cm, and the mean optical transmittance also increased from 79 to 82% in the visible wavelengths. The electro-annealed films showed a higher figure of merit (1.8 x 10{sup -3} {omega}{sup -1}) than the as-deposited ITO films (6.7 x 10{sup -3} {omega}{sup -1}), indicating that electro-annealed ITO films have better optoelectrical performance than as-deposited films.

    Scientific editors are responsible for deciding which articles to publish in their journals. However, we have not found documentation of their required knowledge, skills, and characteristics, or the existence of any formal core competencies for this role. We describe the development of a minimum set of core competencies for scientific editors of biomedical journals. The 14 key core competencies are divided into three major areas, and each competency has a list of associated elements or descriptions of more specific knowledge, skills, and characteristics that contribute to its fulfillment. We believe that these core competencies are a baseline of the knowledge, skills, and characteristics needed to perform competently the duties of a scientific editor at a biomedical journal.

  20. Junction characteristics of ITO/PANI-ZnS/Ag and ITO/PANI-CdS/Ag Schottky diodes: a comparative study

    Science.gov (United States)

    Dey, S. K.; Baglari, S.; Sarkar, D.

    2016-01-01

    Schottky junctions are constructed by depositing PANI-ZnS and PANI-CdS nanocomposite thin films on ITO electrodes. Current-voltage ( I- V) measurements of these systems are performed as a function of temperature in the range of 313-363 K. These junctions show Schottky diode nature. Various parameters, such as saturation current ( I 0), ideality factor ( n), barrier height ( ∅ 0) and series resistance ( R S), are calculated from diode characteristics relations. These parameters show strong temperature dependence. The values of I 0 and ∅ increase with increasing temperature, whereas the values of n and R S show decreasing trend. A Richardson plot of the data shows nonlinear behaviour with Richardson constant 76 and 45 A cm-2 K-2 for PANI-ZnS and PANI-CdS nanocomposite thin films, respectively.

  2. Martin Stutzmann: Editor, Teacher, Scientist and Friend

    Cardona, Manuel

    2005-03-01

    On 2 January 1995 Martin Stutzmann became Editor-in-Chief of physica status solidi, replacing Professor E. Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality

    The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship - emphasizing the importance of responsibility and accountability -, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors' Network of the European Society of Cardiology.

  17. Personal reflections from the fifth editor of Human Factors.

    Science.gov (United States)

    Williges, Robert C

    2008-06-01

    The fifth editor of Human Factors provides reflections on journal publication spanning four volumes printed from 1976 to 1980. During that period, most of the publication and management activities were handled by volunteer efforts of the editor, the editorial board, and the editor's organization. Electronic word processing was not readily available, and most publication tasks required laborious clerical support, resulting in long publication lags. The editor provides reflection on the steps taken by the Human Factors and Ergonomics Society to separate editorial and production activities during that period to provide more support for the journal editorial duties. This resulted in the Society becoming its own publisher, building the beginning of a publication staff in the central office, and increasing the published page count. Rigorous editorial reviews were used to improve the scientific quality of the journal. The publication emphasis was on empirical research, but theoretical articles and research reviews were also considered for publication. Regular journal articles, short research notes, and special topics were published as ways to broaden the scientific coverage and shorten the publication lag.

    Tin doped indium oxide films are widely used in transparent conducting coatings such as flat panel displays, crystal displays and in optical devices such as solar cells and organic light emitting diodes due to the high electrical resistivity and optical transparency in the visible region of solar spectrum. The deposition parameters have a commendable influence on the optical and electrical properties of the thin films. In this study, ITO thin films were prepared by RF magnetron sputtering. The properties of the films prepared under varying sputtering power were compared using UV- visible spectrophotometry. Effect of sputtering power on the energy band gap, absorption coefficient and refractive index are investigated.

    I am very pleased to announce that Professor Paul Corkum will be taking on the position of Editor-in-Chief at Journal of Physics B: Atomic, Molecular and Optical Physics (J. Phys. B) from the beginning of January 2011. During my term as Editor-in-Chief atomic, molecular and optical science has continued to change rapidly: we have seen ultracold physics widening its original emphasis on Bose-Einstein condensates to the entanglement of light and matter in the most general sense towards a science of information. At the same time attosecond science and interaction of matter with short x-ray pulses develops rapidly. I am very happy that J. Phys. B with Paul Corkum as Editor-in-Chief will play a central role in publishing exciting results from this field. I would like to thank the publishing team at J. Phys. B for their fantastic job, in particular for the quality of the refereeing system the team has been able to maintain while at the same time bringing down the publication times considerably. I thank them all for the help and support they have given me in the role of Editor-in-Chief and wish them the very best for the future. Last and certainly not least I would like to thank you, the authors, referees and readers, for the support of J. Phys. B.

    I started in 2002 as Editor-in-Chief of a well established journal—MST (Measurement Science and Technology). It was a time when modern means of communication offered new opportunities for the scientific community—for all scientists and engineers whether at universities, in industry or at other institutions—to access better quality information in a shorter time. This development helped us to be more efficient in our daily scientific work and to anticipate new trends faster than before. A flood of information was created by different search engines. A few online journals or journals published in emerging countries with a similar profile to MST appeared on the market. MST had to provide new answers in response to these developments. In 2002 I postulated two requirements to the journal. Firstly, the publisher has to be up to date. My impression over the years has been that IOPP is excellently organized. That has made it easier for the board members and all our reviewers to concentrate on the scientific aspects of our input to the journal. During all my visits to Bristol or my contacts with the IOPP staff I always met very professional and enthusiastic staff members. They have not only supported and encouraged the ideas and initiatives of the Editorial Board members, but they have also worked hard on establishing one of the most effective journal operations in the field of measurement science and technology. Many authors are well aware of this. Thus I am able to declare that the first requirement for a successful journal has been met. Secondly, the scientific level has to be high and the journal should attract readers from all over the world. This task was the responsibility of the Editorial Board members and of myself. Our strategy was on the one hand to ensure continuity in MST but on the other hand to be open to new trends and developments. Examples of these new aspects of the journal are fields like micro- and nanometrology, measurement techniques for

    Full Text Available Tin-doped Indium oxide (ITO thin films were prepared by sol-gel dip-coating technique using low-cost metal salts and organic solvents. The coated films were treated without annealing or annealed at 400°C and 600°C in 3% H2/97% N2 mixtures atmosphere. Microstructure, optical, and electrical properties of the prepared ITO films were investigated in detail. The maximum transmittance in the visible range (380–780 nm is 85.6%, and the best resistivity is 5×10−2 Ω-cm when annealed at 600°C in 3% H2/97% N2 mixtures atmosphere. It is found that the optical and electrical properties of the prepared ITO films are strongly related to the microstructure variation. The organic compounds could not be removed completely, and the prepared ITO thin films were not dense when the prepared ITO film was annealed at 600°C in 3% H2/97% N2 mixtures atmosphere, causing the poor conductivity.

    Indium tin oxide (ITO) is the most common transparent electrode used in organic photovoltaics (OPVs), yet limited indium reserves and poor mechanical properties make it non-ideal for large-scale OPV production. To replace ITO, we designed, fabricated, and deployed plasmonic nanostructured electrodes in inverted OPV devices. We found that active layer absorption is significantly impacted by ZnO thickness which affects the optical field distribution inside the resonant cavity formed between the plasmonic nanostructured electrode and top electrode. High quality Cr/Au nanostructured electrodes were fabricated by nanoimprint lithography and deployed in ITO-free inverted devices on glass. Devices with thinner ZnO showed a PCE as high as 5.70% and higher J SC’s than devices on thicker ZnO, in agreement with finite-difference time-domain simulations. In addition, as the active layer was made optically thin, ITO-based devices showed diminished J SC while the resonant cavity effect from plasmonic nanostructured electrodes retained J SC. Preliminary ITO-free, flexible devices on PET showed a PCE of 1.82% and those fabricated on ultrathin and conformable Parylene substrates yielded an initial PCE over 1%. The plasmonic electrodes and device designs in this work show promise for developing highly functioning conformable devices that can be applied to numerous needs for lightweight, ubiquitous power generation.

    The thesis deals with a reactive sputter process for the deposition of ITO- films. In contrast to the usual technique, the sputter targets consists of indium-tin-alloy instead of ceramic ITO. All experiments were conducted on an inline coater with 600 mm target-width. The process is stabilized by a control loop based on optical emission detection. The experiments prove, that this control loop guarantees a long term stability of the outcomes of the coating process.Process parameters, that are crucial for the optical and electrical properties of the deposited thin films are identified and studied. Among them are the flow of oxygen and the substrate temperature but also less obvious parameters such as the distance between target and substrate.Througout the work the focus is on the film deposition with pulsed plasmas. Novel bipolar DC pulse- and pulse package generators are employed for the deposition.In order to shed some light onto the influence of certain pulse parameters on the outcome of a particular coating process, a Monte-Carlo-Simulation of the particle flow in pulsed plasmas is developed. This simulation yields the distribution of particles and their respective energies on deliberately placed planes in the process chamber. Particles under investigation are both sputtered species and neutral sputter gas atoms reflected at the target. The results of this simulation provide an explanation for the influence of certain pulse parameters on the outcome of the coating process. The further investigations deal with the influence of the construction of the process chamber on the coating process. For this purpose, locally resolved optical spectra are recorded. In order to analyse these spectra, a novel connected fit algorithm is developed.This algorithm yields the distribution of certain fitparameters on the substrate. Provided the most complex of the discussed parametrizations of the dielectric function are used, these can be crucial properties such as the carrier

    In this paper, n-ZnO single microwire/p{sup +}-Si heterojunction LEDs are fabricated using the transparent conductive ITO film as an electrode. A distinct UV emission resulting from free exciton recombination in a ZnO single microwire is observed in the electroluminescence. Size difference of ZnO single microwire shows significant influence on emission efficiency. The EL spectra of n-ZnO single microwire/p-Si heterostructure exhibited relatively stronger UV emission which was compared with the EL spectra of n-ZnO single nanowire/p-Si heterostructure and n-ZnO film/p-Si heterostructure, respectively. - Highlights: • The ZnO microwires were synthesized with a vapor phase transport method. • ZnO single microwire/Si LEDs were fabricated using the ITO film as an electrode. • The EL spectra had been compared with n-ZnO film/p-Si heterostructure. • The EL spectra had been compared with n-ZnO single nanowire/p-Si heterostructure.

    Layered double hydroxide (LDH) thin films with different chemical compositions (MgZnAl, MgZnGa, MgGaAl) and varying thicknesses were easily prepared by sol–gel method followed by dip-coating. Films were chemically uniform, transparent and well adhered to a conductive indium tin oxide (ITO) substrate. Structure, chemical composition and morphology of the thin films were characterized by XRD-GADDS, SEM-EDS and AFM. Additionally, the semiconducting properties of all the prepared films were studied through the Mott–Schottky relationship; such properties were closely related to the chemical compositions of the film. The films were characterized after electrochemical treatment and important modifications regarding surface morphology, particle and crystal sizes were observed. An in-depth study was conducted in order to investigate the effect of several different electrochemical treatments on the morphology, particle size distribution and crystal size of LDH thin films. Upon electrochemical treatment, the films' surface became smooth and the particles forming the films were transformed from flaky open LDH platelets to uniformly distributed close-packed LDH nanoparticles. - Highlights: • Semiconducting Mg(Zn)Al(Ga)–LDH/ITO thin films prepared by sol–gel. • LDH thin films show a turbostratic morphology made up of porous flakes. • Electrochemical treatments change the flaky structure into a nanoparticle array.

    The DC electric-field effect on the crystaity of II-VI semiconductor in composite systems has been investigated for CdS-ITO films fabricated via alternative pulsed laser deposition (PLD) of CdS and indium tin oxide (ITO) on electric-field-applied substrates. The alternative laser ablation was performed under irradiation of ArF excimer laser in mixture gas of helium and oxygen. The application of electric-field facilitated the preferential crystal-growth of CdS in nanometer scale at low pressure, whereas all the films grown without the field were amorphous. There is a large difference in the crystallization between the films grown on field-applied and heated substrates; the latter showed the crystal-growth with random orientations. This difference indicates that the existence of electric-field has an influence on the transformation from amorphous to crystalline phase of CdS. The driving force for the field-induced crystallization is also discussed in the light of the Joule heat.

    For a period of 10 years, ending in 2010, the authors investigated atmospheric pollen dispersion of Cryptomeria japonica and Cupressaceae in Ito City. We expect this investigation useful in treating patients with pollen allergy. We set up a Durham sampler on a rooftop of the three-story building in Ito City and counted atmospheric pollen day by day. The results and the local weather conditions were treated statistically on the computer program Microsoft Excel. During the 10 years, in average, initial pollen was observed at January 3; pollen began to release was observed at February 6; final pollen was observed at May 12. The spring seasonal total pollen counts was 5683 grain/cm2. This pollen counts and the previous early winter seasonal pollen counts were correlated statistically. The pollen counts were related with the local weather conditions significantly. The investigations of the atmospheric pollen dispersion of Cryptomeria japonica and Cupressaceae and the weather conditions in the local area are useful to treat patients with the pollen allergy.

    Background Workers manufacturing indium-tin oxide (ITO) are at risk of elevated indium concentration in blood and indium lung disease, but relationships between respirable indium exposures and biomarkers of exposure and disease are unknown. Methods For 87 (93%) current ITO workers, we determined correlations between respirable and plasma indium and evaluated associations between exposures and health outcomes. Results Current respirable indium exposure ranged from 0.4 to 108 μg/m3 and cumulative respirable indium exposure from 0.4 to 923 μg-yr/m3. Plasma indium better correlated with cumulative (rs = 0.77) than current exposure (rs = 0.54) overall and with tenure ≥1.9 years. Higher cumulative respirable indium exposures were associated with more dyspnea, lower spirometric parameters, and higher serum biomarkers of lung disease (KL-6 and SP-D), with significant effects starting at 22 μg-yr/m3, reached by 46% of participants. Conclusions Plasma indium concentration reflected cumulative respirable indium exposure, which was associated with clinical, functional, and serum biomarkers of lung disease. PMID:27219296

    This paper investigates the effects of indium tin oxide (ITO) powders on the driving voltage of polymer-dispersed liquid crystal (PDLC). The threshold voltage (V th ) and driving voltage (V d ) can be reduced through doping the ITO powders; in particular, the V d is 5.8 V when the weight ratio of ITO is 1.5 wt. %. The relationship between the applied voltage and off-time of PDLC has been investigated; the lower the applied voltage, the shorter the off-time. On this basis, the reverse voltage pulse driving method was proposed; this driving method uses the driving signal to reduce the off-time of PDLC.

    Full Text Available Semiconducting single-wall carbon nanotubes (SWCNTs were selecively interacted with tetrathiafulvalene (TTF moiety self-assembled on indium tin oxide (ITO substrate by charge-transfer interaction. The charge-transfer phenomena between two molecules were elucidated by cyclic voltammetry (CV and Raman spectroscopy. CV measurement of TTF-modified ITO substrate as a working electrode presented the difference between heat-treated system and untreated one. The two redox potentials, which are typically related to redox behavior of TTF, were shown in the unheated system during both oxidation and reduction cycles, while the two oxidation peaks were disappeared in the heated system. Raman spectra indicated that the intensities of RBM originated from metallic SWCNTs were much reduced in the heat-treated system, while there were little change in the unheated one. These results revealed that only semiconducting SWNTs were selectively adsorbed on the TTF moiety self-assembled on ITO when the system with heat treatment.

We thank both the authors and the referees for working with us on the rather tight schedule necessary to release the issue within one year of the date of the conference. We also thank the invited speakers, B Eckhardt, L Tuckerman, and J M Vega, for contributing keynote papers to this special issue. The series of BIFD symposia started as a small workshop in Madeira, Portugal, in 2004 with no more than 20 participants. This number increased rapidly during the second and third symposia held in 2006 (Denmark) and 2009 (United Kingdom), with 40 and 110 participants, respectively. The 4th BIFD symposium has consolidated this event as one of the leading conferences in hydrodynamic stability, with nearly 200 participants from around the world. The main goal of this conference is to bring together scientists and engineers from different disciplines directly or indirectly related to fluid dynamics, bifurcation theory and hydrodynamic stability theory. The conference covered many research areas within the aforementioned fields, ranging from thermal, shear and centrifugal flows to biofluids, films, drops, viscoelastic flows and magnetohydrodynamics. The structure of the conference, with invited plenary talks and focused sessions, helped the participants find their home in the conference and share state-of-the-art knowledge within the field of hydrodynamic instabilities. The financial support from MICINN (Spanish Ministry of Science and Innovation, Grant no FIS2009-08065-E) and UPC (Universitat Politècnica de Catalunya) is greatly appreciated.

    This work describes the incorporation of SiNWs/AuNPs composite as a sensing material for DNA detection on indium tin-oxide (ITO) coated glass slide. The morphology of SiNWs/AuNPs composite as the modifier layer on ITO was studied by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). The morphological studies clearly showed that SiNWs were successfully decorated with 20 nm-AuNPs using self-assembly monolayer (SAM) technique. The effective surface area for SiNWs/AuNPs-modified ITO enhanced about 10 times compared with bare ITO electrode. SiNWs/AuNPs nanocomposite was further explored as a matrix for DNA probe immobilization in detection of dengue virus as a bio-sensing model to evaluate its performance in electrochemical sensors. The hybridization of complementary DNA was monitored by differential pulse voltammetry (DPV) using methylene blue (MB) as the redox indicator. The fabricated biosensor was able to discriminate significantly complementary, non-complementary and single-base mismatch oligonucleotides. The electrochemical biosensor was sensitive to target DNA related to dengue virus in the range of 9.0–178.0 ng/ml with detection limit of 3.5 ng/ml. In addition, SiNWs/AuNPs-modified ITO, regenerated up to 8 times and its stability was up to 10 weeks at 4 °C in silica gel. - Highlights: • A sensitive biosensor is presented for detection of dengue virus. • SiNWs and AuNPs used as nanocomposite layers on ITO for construction of biosensor • The detection mechanism is based on the interaction of MB with DNA bonded on AuNPs. • The reduction signal of MB decreases upon complementary hybridization.

    2010-10-01

    This article is part of an occasional series profiling editors of the American Journal of Clinical Hypnosis (AJCH). William E. Edmonston was the second editor, succeeding Milton H. Erickson. His research focused on the use of conditioning paradigms and psychophysiological measures to explore a wide variety of hypnotic phenomena, leading to a "neo-Pavlovian" theory of neutral hypnosis as physiological relaxation (anesis). A longtime professor of psychology at Colgate University, he created an interdisciplinary undergraduate major in neuroscience, and was named New York State College Professor of the Year in 1988. He gave the Journal a new look, and a greater balance of clinical and experimental papers. The article also provides background on George Barton Cutten, George H. Estabrooks, and Frank A. Pattie, pioneers of hypnosis who were linked to Edmonston.

    In a recent Letter to the Editor, Armstrong raises concern that the design of the study reported by Six et al. was not consistent with the product label for treatment of Amblyomma americanum, since fluralaner was not re-administered 56 days after the initial treatment. The Authors disagree with this assessment and confirm that the design was appropriate, and therefore the results and conclusions for the entire study period are valid.

    Plagiarism and inadequate citing appear to have reached epidemic proportions in research publication. This article discusses how plagiarism is defined and suggests some possible causes for the increase in the plagiarism disease. Most editors do not have much tolerance for text re-use with inadequate citation regardless of reasons why words are copied from other sources without correct attribution. However, there is now some awareness that re-use of words in research articles to improve the writing or “the English” (which has become a common practice) should be distinguished from intentional deceit for the purpose of stealing other authors’ ideas (which appears to remain a very rare practice). Although it has become almost as easy for editors to detect duplicate text as it is for authors to re-use text from other sources, editors often fail to consider the reasons why researchers resort to this strategy, and tend to consider any text duplication as a symptom of serious misconduct. As a result, some authors may be stigmatized unfairly by being labeled as plagiarists. The article concludes with practical advice for researchers on how to improve their writing and citing skills and thus avoid accusations of plagiarism. PMID:21957412

  1. A perspective on computer documentation: System developer vs. technical editor

    1995-12-31

    Between the computer-knowledgeable {open_quotes}techie{close_quotes} and the technical writer is a chasm created by differences in knowledge bases and skills. Although this gap is widened by misunderstandings and misconceptions of system development roles, it is bridged by mutual need and dual appreciation. Often the editor/writer is {open_quotes}behind{close_quotes} from beginning to end. The writer normally joins the team after the programmers are well into system development and do not want to {open_quotes}waste time{close_quotes} discussing fundamentals. The writer is usually excluded from technical discussions because it is assumed that he/she would not understand anyway. Later in the system development cycle, the writer has no time to polish the documentation before a new version of the software is issued which implies that the documentation must be revised. Nevertheless, the editor/writer`s product is critical for the end-user`s appreciation of the software, a fact which promotes unity to complete the comprehensive package of software and documentation. This paper explores the planks in the bridge that spans the chasm between developers and their fundamental PR agents, the technical editors/writers. This paper defines approaches (e.g., The Circling Theory) and techniques (Bold Thrust!) employed for effective communication -- between software developer and technical writer as well as between the software and the end-user.

    Full Text Available This paper reports impressive improvements in the optical and electrical performance of metal-oxide-semiconductor (MOS-structure silicon solar cells through the incorporation of plasmonic indium nanoparticles (In-NPs and an indium-tin-oxide (ITO electrode with periodic holes (perforations under applied bias voltage. Samples were prepared using a plain ITO electrode or perforated ITO electrode with and without In-NPs. The samples were characterized according to optical reflectance, dark current voltage, induced capacitance voltage, external quantum efficiency, and photovoltaic current voltage. Our results indicate that induced capacitance voltage and photovoltaic current voltage both depend on bias voltage, regardless of the type of ITO electrode. Under a bias voltage of 4.0 V, MOS cells with perforated ITO and plain ITO, respectively, presented conversion efficiencies of 17.53% and 15.80%. Under a bias voltage of 4.0 V, the inclusion of In-NPs increased the efficiency of cells with perforated ITO and plain ITO to 17.80% and 16.87%, respectively.

    We have investigated the photovoltaic properties of an inverted bulk heterojunction (BHJ) cell in a device with an indium-tin-oxide (ITO)/electron selective layer (ESL)/P3HT:PCBM active layer/MoOx/Ag multilayered structure. The insertion of only single layer of poly(diallyl-dimethyl-ammonium chloride) (PDDA) cationic polymer film (or poly(ethyleneimine) (PEI) polymeric interfacial dipole layer) and titanium oxide nanosheet (TN) films as an ESL effectively improved cell performance. Abnormal S-shaped curves were observed in the inverted BHJ cells owing to the contact resistance across the ITO/active layer interface and the ITO/PDDA/TN/active layer interface. The series resistance across the ITO/ESL interface in the inverted BHJ cell was successfully reduced using an interfacial layer with a positively charged surface potential with respect to ITO base electrode. The positive dipole in PEI and the electronic charge phenomena at the electrophoretic deposited TN (ED-TN) films on ITO contributed to the reduction of the contact resistance at the electrode interface. The surface potential measurement revealed that the energy alignment by the transfer of electronic charges from the ED-TN to the base electrodes. The insertion of the ESL with a large positive surface potential reduced the potential barrier for the electron injection at ITO/TN interface and it improved the photovoltaic properties of the inverted cell with an ITO/TN/active layer/MoOx/Ag structure.

    Following the FAIR data principles, research data should be Findable, Accessible, Interoperable and Reuseable. Publishing data under these principles requires to assign persistent identifiers to the data and to generate rich machine-actionable metadata. To increase the interoperability, metadata should include shared vocabularies and crosslink the newly published (meta)data and related material. However, structured metadata formats tend to be complex and are not intended to be generated by individual scientists. Software solutions are needed that support scientists in providing metadata describing their data. To facilitate data publication activities of 'GFZ Data Services', we programmed an XML metadata editor that assists scientists to create metadata in different schemata popular in the earth sciences (ISO19115, DIF, DataCite), while being at the same time usable by and understandable for scientists. Emphasis is placed on removing barriers, in particular the editor is publicly available on the internet without registration [1] and the scientists are not requested to provide information that may be generated automatically (e.g. the URL of a specific licence or the contact information of the metadata distributor). Metadata are stored in browser cookies and a copy can be saved to the local hard disk. To improve usability, form fields are translated into the scientific language, e.g. 'creators' of the DataCite schema are called 'authors'. To assist filling in the form, we make use of drop down menus for small vocabulary lists and offer a search facility for large thesauri. Explanations to form fields and definitions of vocabulary terms are provided in pop-up windows and a full documentation is available for download via the help menu. In addition, multiple geospatial references can be entered via an interactive mapping tool, which helps to minimize problems with different conventions to provide latitudes and longitudes. Currently, we are extending the metadata editor

    Fast selective pattering with high precession on 175 nm ITO thin film with IR ps lasers is investigated. Ablation parameters are optimized with detailed studies on the scribed depth, topography, and particle generation using AFM and SEM. A comparison of 10 and 150 ps laser revealed that the shorter pulse (10 ps) laser is more appropriate in selective and partial ablation; up to 20 nm resolution for controlled depth with multipulses having energy below the damage threshold is demonstrated. The experimental results are interpreted to involve stress assisted ablation mechanism for the 10 ps laser while thermal ablation along with intense melting occurs for 150 ps laser. The transition between these regimes is estimated to occur at approximately 30 ps.

    In this paper, the fabrication and characterization of a heterojunction solar cell based on p-Cu2O/n-ZnO nanowires on ITO glass are presented. ZnO aligned nanocrystal seed layer is firstly prepared by RF magnetron sputtering technique, and then vertical ZnO nanowire arrays with an acicular crystal structure are obtained by using a chemical bath deposition processing. The results indicate that the ZnO nanowires with a diameter of about 50 nm and 500 nm in length can be easily obtained. The absorption and transmittance of the ZnO nanowires are studied. It is also noted that the Cu2O can fill well into the space between ZnO nanowires by an electrodeposition process. Furthermore, the effect of the Cu2O orientation on the cell performance is also presented.

    ITO/Y₂O₃/Ag devices were fabricated using Y₂O₃ films as insulator. Four intense and sharp lines with half-peak width of 4 nm were observed for the 293.78 nm InI, 316.10 nm InI, 444.82 nm InII and 403.07 nm InIII transitions. Luminescence mechanism was illustrated by cross-section of the devices based on the analysis of surface morphology. Under the action of strong electric field, the loss of K-shell electrons led to the occurrence of characteristic radiation of indium ions. In addition, the device with turn-on voltage of 10V demonstrates typical I-V diode characteristics. Moreover, Y₂O₃/In₂O₃ multiple films as the insulation layer instead of single Y₂O₃ films was found to improve the device performance with excellent CIE (x, y) coordinates (0.16, 0.03).

    2017-10-01

    Absorption of an photonic configuration with 2D accumulation electron gas is theoretically investigated in the first optical window of biological tissue. The configuration consists of a Bragg mirror, an ITO-dielectric heterostructure and a metal film. Our results show that the configuration can realize perfect absorption (reaches 99.98%) of specific wavelength light at matched electron density of the accumulation electron gas. Moreover, the influences of different parameters on the perfect absorption are investigated, which allows us accurately tune the absorption spectrum of the configuration. In addition, manufacture discrepancies of film thicknesses are simulated through introducing random thickness errors in the configuration. It is found that the discrepancies of film thicknesses dramatically affect the absorption spectrum of the configuration. Fortunately, this manufacture impact can be perfectly remedied by changing the electron density of the accumulation electron gas and the incident angle of light.

    Directory of Open Access Journals (Sweden)

    Hongfeng Wang

    2016-04-01

    Full Text Available This article reports giant magnetic field effects on the Seebeck coefficient by exerting a Lorentz force on charge diffusion based on vertical multi-layer ITO/PEDOT:PSS/Au thin-film devices. The Lorentz force, induced by an external magnetic field, changes the charge transport and consequently generates angular dependent magnetoresistance. The proposed mechanism of the magneto-Seebeck effect is proved by measuring the magnetoresistance at a parallel, 45o and perpendicular angle to the temperature gradient. The gradual change of the magnetoresistance from a parallel to perpendicular angle indicates that the Lorentz force is a key driving force to develop the magneto-Seebeck effect. Therefore, our experimental results demonstrate a magnetic approach to control the thermoelectric properties in organic materials.

    Directory of Open Access Journals (Sweden)

    2013-01-01

    Full Text Available Described here is fabrication of a pH-sensitive, optically transparent transducer composed of a planar indium-tin oxide (ITO electrode overcoated with a poly(aniline (PANI thin film and a porous sol-gel layer. Adsorption of the PANI film renders the ITO electrode sensitive to pH, whereas the sol-gel spin-coated layer makes the upper surface compatible with fusion of phospholipid vesicles to form a planar supported lipid bilayer (PSLB. The response to changes in the pH of the buffer contacting the sol-gel/PANI/ITO electrode is pseudo-Nernstian with a slope of 52 mV/pH over a pH range of 4–9. Vesicle fusion forms a laterally continuous PSLB on the upper sol-gel surface that is fluid with a lateral lipid diffusion coefficient of 2.2 μm2/s measured by fluorescence recovery after photobleaching. Due to its lateral continuity and lack of defects, the PSLB blocks the pH response of the underlying electrode to changes in the pH of the overlying buffer. This architecture is simpler to fabricate than previously reported ITO electrodes derivatized for PSLB formation and should be useful for optical monitoring of proton transport across supported membranes derivatized with ionophores and ion channels.

    2017-09-05

    To provide orthogonal solvent processable surface modification and improve the device stability of bulk-heterojunction polymer solar cells (PSCs), n-type semiconducting material naphthalene diimide (NDI) was chemically introduced onto the ITO surface as a cathode interlayer (CIL) using 3-bromopropyltrimethoxysilane (BrTMS) as a coupling agent. After modification, the work function of ITO can be decreased from 4.70 to 4.23 eV. The modified ITO cathode was applied in inverted PSCs based on PTB7-Th:PC71BM. With the CIL modification, a champion power conversion efficiency (PCE) of 5.87% was achieved, showing a dramatic improvement compared to that of devices (PCE = 3.58%) without CIL. More importantly, with these chemical bonded interlayers, the stability of inverted PSCs was greatly enhanced. The improved PCE and stability can be attributed to the increased open-circuit voltage and the formation of robust chemical bonds in NDI-TMS films, respectively. This study demonstrated that chemical modification of ITO with n-type semiconducting materials provides an avenue for not only solving the solvent orthogonal problem but also improving the device performance in terms of the PCE and the stability.

    The structural and optical properties of multilayer ITO/SiO{sub 2}/Ag composites are studied. In these composites, the ITO (indium-tin oxide) layer is produced by two different methods: electron-beam evaporation and a combined method including electron-beam evaporation and subsequent magnetron sputtering. It is shown that the reflectance of the composite based on the ITO film produced by electron-beam evaporation is substantially lower. This can be attributed to the strong absorption of light at both boundaries of the SiO{sub 2} layer, which results from the complex surface profile of ITO films deposited by electron-beam evaporation. Samples with a film deposited by the combined method have a reflectance of about 90% at normal light incidence, which, combined with their higher electrical conductivity, makes these samples advantageous for use as reflective contacts to the p-type region of AlInGaN light-emitting diodes of the flip-chip design.

    The variation of oxygen concentration in the Indium Tin Oxide (ITO) structure highly impacts its electrical and optical characteristics. In this work, we investigated the effect of oxygen partial flow (O2/O2+Ar) and deposition pressure (p) on the refractive index (n) of reactive sputtered ITO thin films. A statistical study with a Genetic Algorithm (GA) optimization was implemented to find optimal deposition conditions for obtaining particular refractive indices. Several samples of ITO thin films with refractive indices ranging from 1.69 - 2.1 were deposited by DC sputtering technique at various oxygen concentrations and deposition pressures, in order to develop the statistical database. A linear polynomial surface was locally fitted to the data of O2/O2+Ar, p, and n of deposited films. This surface was then used as the fitness function of the GA. By defining the desired n as the objective value of the GA, the optimized deposition conditions can be found. Two cases were experimentally demonstrated, with the GA determining the needed process parameters to deposit ITO with n=2.2 and n=1.6. Measured results were very close to desired values, with n=2.25 and n=1.62, demonstrating the effectiveness of this method for predicting needed reactive sputtering conditions to enable arbitrary refractive indices.

  1. Influence of ITO-Silver Wire Electrode Structure on the Performance of Single-Crystal Silicon Solar Cells

    Full Text Available This study aimed to explore the effect of various electrode forms on single-crystal silicon solar cells by changing their front and back electrode structures. The high light penetration depth of the Indium Tin Oxide (ITO and the high conductivity of the silver wire that were coated on the single crystal silicon solar cells increased photoelectron export, thus increasing the efficiency of the solar cell. The experiment utilized a sol-gel solution containing phosphorus that was spin coated on single-crystal silicon wafers; this phosphorus also served as a phosphorus diffusion source. A p-n junction was formed after annealing at high temperature, and the substrate was coated with silver wires and ITO films of various structures to produce the electrodes. This study proposed that applying a heat treatment to the aluminum of back electrodes would result in a higher efficiency for single-crystal silicon solar cells, whereas single-crystal silicon solar cells containing front electrodes with ITO film coated with silver wires would result in efficiencies that are higher than those achieved using pure ITO thin-film electrodes.

    I am very pleased to join the outstanding leadership team for the journal Nuclear Fusion as Scientific Editor. The journal's high position in the field of fusion energy research derives in no small measure from the efforts of the IAEA team in Vienna, the production and marketing of IOP Publishing, the Board of Editors led by its chairman Mitsuru Kikuchi, the Associate Editor for Inertial Confinement Max Tabak and the outgoing Scientific Editor, Paul Thomas. During Paul's five year tenure submissions have grown by over 40%. The usage of the electronic journal has grown year by year with about 300 000 full text downloads of Nuclear Fusion articles in 2011, an impressive figure due in part to the launch of the full 50 year archive. High quality has been maintained while times for peer review and publishing have been reduced and the journal achieved some of the highest impact factors ever (as high as 4.27). The journal has contributed greatly to building the international scientific basis for fusion. I was privileged to serve from 2003 to 2010 as chairman of the Coordinating Committee for the International Tokamak Physics Activity (ITPA) which published in Nuclear Fusion the first ITER Physics Basis (1999) and its later update (2007). The scientific basis that has been developed to date for fusion has led to the construction of major facilities to demonstrate the production of power-plant relevant levels of fusion reactions. We look forward to the journal continuing to play a key role in the international effort toward fusion energy as these exciting major facilities and the various approaches to fusion continue to be developed. It is clear that Nuclear Fusion maintains its position in the field because of the perceived high quality of the submissions, the refereeing and the editorial processes, and the availability and utility of the online journal. The creation of the Nuclear Fusion Prize, led by the Board of Editors chairman Mitsuru Kikuchi, for the most outstanding

    We report on the lasing of III-nitride nonpolar, violet, vertical-cavity surface-emitting lasers (VCSELs) with III-nitride tunnel-junction (TJ) intracavity contacts and ion implanted apertures (IIAs). The TJ VCSELs are compared to similar VCSELs with tin-doped indium oxide (ITO) intracavity contacts. Prior to analyzing device results, we consider the relative advantages of III-nitride TJs for blue and green emitting VCSELs. The TJs are shown to be most advantageous for violet and UV VCSELs, operating near or above the absorption edge for ITO, as they significantly reduce the total internal loss in the cavity. However, for longer wavelength III-nitride VCSELs, TJs primarily offer the advantage of improved cavity design flexibility, allowing one to make the p-side thicker using a thick n-type III-nitride TJ intracavity contact. This offers improved lateral current spreading and lower loss, compare to using ITO and p-GaN, respectively. These aspects are particularly important for achieving high-power CW VCSELs, making TJs the ideal intracavity contact for any III-nitride VCSEL. A brief overview of III-nitride TJ growth methods is also given, highlighting the molecular-beam epitaxy (MBE) technique used here. Following this overview, we compare 12 mu m aperture diameter, violet emitting, TJ and ITO VCSEL experimental results, which demonstrate the significant improvement in differential efficiency and peak power resulting from the reduced loss in the TJ design. Specifically, the TJ VCSEL shows a peak power of similar to 550 mu W with a threshold current density of similar to 3.5 kA/cm(2), while the ITO VCSELs show peak powers of similar to 80 mu W and threshold current densities of similar to 7 kA/cm

    professionals to demonstrate that value in action. Other advantages include the perspectives provided by such special-section authors, editors, and reviewers that draw in a diverse suite of geoscientists and engineers that truly represent the interpretation community. Where there are advantages, there are also disadvantages. First, the vast majority of special-section editors are “new to the job,” never having served on an editorial board of a peer-reviewed scientific journal. The primary objective of this “From the Editor” note is to clarify the roles and responsibilities of this task. Second, many of the selected reviewers may never have had the opportunity to review a paper for publication. They too are new to the job. The August issue of the From the Editor column (Bui et al., 2017) titled “Qualities of a good reviewer” directly addresses this challenge. In this article, we encourage the reviewers to help the authors to construct a quality, well-referenced paper because many of them, too, are new to the job. The third disadvantage is that the special-section format skews the citation-index metrics. Obviously, if the special-section editors identify a good oral presentation and request the author to develop a full-length paper, the chances of acceptance are higher, thus lowering the citation index score. More on this conundrum will be found in the From the Editor column in the February 2018 issue of Interpretation. The remainder of this short article addresses the issues specific to the special-section editors.

    On 1 January, 2004, I assumed the position of Editor-in-Chief of Journal of Physics D: Applied Physics. I will start by saying that I will do my best to justify the confidence of the journal management and publishing staff in my abilities. I was fortunate to have been able to work, as an Editorial Board member, with my predecessor, the previous Editor-in-Chief, Professor Allister Ferguson. Allister has provided a high degree of intellectual stewardship for the journal in the last five years. He has made the job appear a worthy challenge for me. I therefore take this opportunity to thank Allister on behalf of the Editorial Board and publishing staff of the journal. Several other factors contributed to my decision to accept this position. The first is the group of people who actually go about the business of publishing. The Senior Publisher, Nicola Gulley (and her predecessor Sophy Le Masurier); the Managing Editor, Jill Membrey; the Publishing Administrators, Nina Blakesley and Sarah Towell; the Production Editor, Katie Gerrard and their office staff form an amazing group and have managed to make the operation of the journal incredibly efficient. An index of this is the speed with which incoming manuscripts are processed. The average time between the receipt of a manuscript and its web publication, if accepted, is 130 days. This is three to five times shorter than for most other journals. A factor that contributes to this success is a responsive pool of referees that the publishing staff have as a valuable resource. Ultimately, the standard bearers of any journal are the referees. Therefore, a grateful `thank you' is due from all of us at J. Phys. D to all our referees, who diligently perform this honourable task. The Associate Editors of the journal, Professors Lawler, Margaritondo and O'Grady, also provide immense scientific leadership. They help in defining new directions for the journal and in the publishing process. Last, but not least, a remarkable asset of

    On 1 January 2012 I will be assuming the position of Editor-in-Chief of the journal Semiconductor Science and Technology (SST). I am flattered by the confidence expressed in my ability to carry out this challenging job and I will try hard to justify this confidence. The previous Editor-in-Chief, Laurens Molenkamp, University of Würzburg, Germany, has worked tirelessly for the last ten years and has done an excellent job for the journal. Everyone at the journal is profoundly grateful for his leadership and for his achievements In 2012 several new members will join the Editorial Board: Professor Deli Wang (University of California, San Diego) with considerable expertise in semiconductor nanowires, Professor Saskia Fischer (Humboldt University, Berlin, Germany) with a background in semiconductor quantum devices, and Professor Erwin Kessels (Eindhoven University of Technology, Netherlands) with extensive experience in plasma processing of thin films and gate oxides. In particular, I want to express my gratitude to Professor Israel Bar-Joseph (Weizmann Institute of Science, Israel) and Professor Maria Tamargo (The City College of New York, USA), who will leave next year and who have vigorously served the Editorial Board for years. The journal has recently introduced a fast-track option for manuscripts. This option is a high-quality, high-profile outlet for new and important research across all areas of semiconductor research. Authors can expect to receive referee reports in less than 20 days from submission. Once accepted, you can expect the articles to be online within two or three weeks from acceptance and to be published in print in less than a month. Furthermore, all fast-track communications published in 2011 will be free to read for ten years. More detailed information on fast-track publication can be found on the following webpage: http://iopscience.iop.org/0268-1242/page/Fast track communications It is encouraging to see that since the journal introduced pre

    While they have different electronic properties n-type MoO{sub 3} and p-type NiO are very efficient as buffer layers between the ITO anode and the organic electron donor in organic photovoltaic cells. While it is admitted that MoO{sub 3} is n-type, its band structure is still under study. Here, the band alignment at the interface of an ITO/MoO{sub 3} heterojunction is studied by X-ray photoelectron spectroscopy (XPS). The same study is realized on the structure ITO/NiO, NiO being a p-type semiconductor. The measurements have been performed on samples obtained under the same experimental conditions as those used to achieve organic photovoltaic cells. The MoO{sub 3} (NiO) upper layer was 3 nm thick. The semidirect XPS technique used to measure the band offsets allows us to estimate the band discontinuities at the interface ITO/MoO{sub 3}: {Delta}E{sub v} = 0.50 eV and {Delta}E{sub c} = 0.90 eV, while at the interface ITO/NiO we have {Delta}E{sub v} = -2.10 eV and {Delta}E{sub c} = -1.90 eV. Therefore, n-type MoO{sub 3} and p-type NiO, which are both very efficient anode buffer layers (ABLs), exhibit different band structure at the contact with ITO. However, the measurement, by means of a Kelvin probe, of the work functions of the structures ITO/NiO and ITO/MoO{sub 3}, shows that they are close and significantly higher than that of ITO alone.

  16. Comments on ``Anonymous Reviews'' An Editor's View of Anonymous Reviews

    Science.gov (United States)

    Goff, John A.

    I have read with great interest the recent Forum commentaries in Eos by Myrl Beck, Charles Robinove, Robert Criss, and Anne Hofmeister regarding anonymous reviews. I heartily support their position that anonymous reviews should be avoided. I have not written an anonymous review in ages (and regret the few that I did), and have always appreciated and respected greatly anyone who signs a critical review of one of my own papers. However, I would like to add some perspective from the editorial standpoint. I have served as JGR associate editor for 3 years (never anonymously!), and as Eos editor for seismology and tectonophysics for 4. Over the years, I have rejected a fair number of papers, most of those based on anonymous reviews (fortunately, none of the above commentators was one of them). The vast majority of anonymous reviews I received were well considered. While I would wish that all reviews were signed, I don't think we can summarily dismiss the fear that many would have of enmity and reprisal over a critical review. Some of these fears are likely justified. On more than one occasion, have I witnessed overly aggressive responses on the part of authors to anonymous reviews that I considered to be entirely fair and constructive in their criticisms. I do think we need to do all we can to discourage anonymous reviews, but it will be difficult to completely remove that choice from the process.

  18. Can editors save peer review from peer reviewers?

    Directory of Open Access Journals (Sweden)

    Rafael D'Andrea

    Full Text Available Peer review is the gold standard for scientific communication, but its ability to guarantee the quality of published research remains difficult to verify. Recent modeling studies suggest that peer review is sensitive to reviewer misbehavior, and it has been claimed that referees who sabotage work they perceive as competition may severely undermine the quality of publications. Here we examine which aspects of suboptimal reviewing practices most strongly impact quality, and test different mitigating strategies that editors may employ to counter them. We find that the biggest hazard to the quality of published literature is not selfish rejection of high-quality manuscripts but indifferent acceptance of low-quality ones. Bypassing or blacklisting bad reviewers and consulting additional reviewers to settle disagreements can reduce but not eliminate the impact. The other editorial strategies we tested do not significantly improve quality, but pairing manuscripts to reviewers unlikely to selfishly reject them and allowing revision of rejected manuscripts minimize rejection of above-average manuscripts.

    Chemical restraints for use in macromolecular structure refinement are produced by a variety of methods, including a number of programs that use chemical information to generate the required bond, angle, dihedral, chiral and planar restraints. These programs help to automate the process and therefore minimize the errors that could otherwise occur if it were performed manually. Furthermore, restraint-dictionary generation programs can incorporate chemical and other prior knowledge to provide reasonable choices of types and values. However, the use of restraints to define the geometry of a molecule is an approximation introduced with efficiency in mind. The representation of a bond as a parabolic function is a convenience and does not reflect the true variability in even the simplest of molecules. Another complicating factor is the interplay of the molecule with other parts of the macromolecular model. Finally, difficult situations arise from molecules with rare or unusual moieties that may not have their conformational space fully explored. These factors give rise to the need for an interactive editor for WYSIWYG interactions with the restraints and molecule. Restraints Editor, Especially Ligands (REEL) is a graphical user interface for simple and error-free editing along with additional features to provide greater control of the restraint dictionaries in macromolecular refinement.

    Metadata handling is a key factor in preserving and reusing scientific data. In recent years, standardized structural metadata has become widely used in Geoscience communities. However, there exist many different standards in Geosciences, such as the current version of the Federal Geographic Data Committee's Content Standard for Digital Geospatial Metadata (FGDC CSDGM), the Ecological Markup Language (EML), the Geography Markup Language (GML), and the emerging ISO 19115 and related standards. In addition, there are many different subsets within the Geoscience subdomain such as the Biological Profile of the FGDC (CSDGM), or for geopolitical regions, such as the European Profile or the North American Profile in the ISO standards. It is therefore desirable to have a software foundation to support metadata creation and editing for multiple standards and profiles, without re-inventing the wheels. We have developed a software module as a generic, flexible software system to do just that: to facilitate the support for multiple metadata standards and profiles. The software consists of a set of modules for the Drupal Content Management System (CMS), with minimal inter-dependencies to other Drupal modules. There are two steps in using the system's metadata functions. First, an administrator can use the system to design a user form, based on an XML schema and its instances. The form definition is named and stored in the Drupal database as a XML blob content. Second, users in an editor role can then use the persisted XML definition to render an actual metadata entry form, for creating or editing a metadata record. Behind the scenes, the form definition XML is transformed into a PHP array, which is then rendered via Drupal Form API. When the form is submitted the posted values are used to modify a metadata record. Drupal hooks can be used to perform custom processing on metadata record before and after submission. It is trivial to store the metadata record as an actual XML file

    The indium tin oxide (ITO/N-Si) solar cells have been fabricated by spray pyrolysis technique. The silicon wafers are heated at 500 Celsius degrees with different oxidation time (2-20 min). The best values obtained for ITO/Si solar cell output parameters; open circuit voltage V{sub o}c, short circuit current density J{sub s}c, fill factor FF and efficiency {eta} are 0.48 V, 15 mA/cm{sup 2}, 0.7 and 10.1% respectively. The preceding results were obtained under conditions of 5 minutes oxidation time and the surface area equal to 8 mm{sup 2} when the light intensity is 50 MW/ cm{sup 2}.

    The development of a practical alternative to indium tin oxide (ITO) is one of the most important issues in flexible optoelectronics. In spite of recent progress in this field, existing approaches to prepare transparent electrodes do not satisfy all of their essential requirements. Here, we present a new substrate-embedded tall (~350 nm) and thin (~30 nm) three-dimensional (3D) metal grid mesh structure with a large area, which is prepared via secondary sputtering. This structure satisfies most of the essential requirements of transparent electrodes for practical applications in future opto-electronics: excellent optoelectronic performance (a sheet resistance of 9.8 Ω □-1 with a transmittance of 85.2%), high stretchability (no significant change in resistance for applied strains strong adhesion to polymer substrates (it survives attempted detachment with 3M Scotch tape). Such outstanding properties are attributed to the unique substrate-embedded 3D structure of the electrode, which can be obtained with a high aspect ratio and in high resolution over large areas with a simple process. As a demonstration of its suitability for practical applications, our transparent electrode was successfully tested in a flexible touch screen panel. We believe that our approach opens up new practical applications in wearable electronics.The development of a practical alternative to indium tin oxide (ITO) is one of the most important issues in flexible optoelectronics.

    Progressive smart photovoltaic technologies including heterostructures a-SiC/c-Si with ITO antireflection film are one of the prospective replacements of conventional photovoltaic silicon technology. Our paper is focused on the investigation of heterostructures a-SiC/c-Si provided with a layer of ITO (indium oxide/tin oxide 90/10 wt.%) which acts as a passivating and antireflection coating. Prepared photovoltaic cell structure was investigated at various temperatures and the influence of temperature on its operation was searched. The investigation of the dynamic properties of heterojunction PV cells was carried out using impedance spectroscopy. The equivalent AC circuit which approximates the measured impedance data was proposed. Assessment of the influence of the temperature on the operation of prepared heterostructure was carried out by analysis of the temperature dependence of AC equivalent circuit elements.

    This paper reports an abnormal coexistence of different resistive switching behaviors including unipolar (URS), bipolar (BRS), and threshold switching (TRS) in an Al/NiO/indium tin oxide (ITO) structure fabricated by chemical solution deposition. The switching behaviors have been strongly dependent on compliance current (CC) and switching processes. It shows reproducible URS and BRS after electroforming with low and high CC of 1 and 3 mA, respectively, which is contrary to previous reports. Furthermore, in the case of high-forming CC, TRS is observed after several switching cycles with a low-switching CC. Analysis of current-voltage relationship demonstrates that Poole-Frenkel conduction controlled by localized traps should be responsible for the resistance switching. The unique behaviors can be dominated by Joule heating filament mechanism in the dual-oxygen reservoir structure composed of Al/NiO interfacial layer and ITO. The tunable switching properties can render it flexible for device applications.

    2009-01-01

    Full Text Available In this paper we investigate charge carrier recombination processes in polymer based photodetector ITO/PEDOT:PSS/MEH-PPV/Al. The major carriers are the hole polarons created by the photoexcitation in the active MEH-PPV film. The model used in this paper is based on the continuity equation and drift-diffusion equation for hole polarons. We assume the Poole-Frenkel expression for field dependence of the hole polaron mobility. The internal quantum efficiency dependence on incident photon flux density, incident light wavelength and applied electric field is included in the model. The simulated photocurrent density spectra for two different, assumed, recombination mechanisms, linear (monomolecular and square (bimolecular is compared with our experimental results. The bimolecular recombination mechanism applied in our model is assumed to be of Langevin type. The agreement between the measured and the calculated data unambiguously indicate that the hole polaron recombination mechanism in the MEH-PPV film is bimolecular with bimolecular rate constant depending on the external electric field. For the established recombination mechanism the theoretical prediction of the photocurrent density spectra shows excellent agreement with the measured spectra in wide range of inverse bias voltages (from 0 to -8 V.

    This paper reports on electrical characterization of ITO/PEDOT:PSS/PTCDA/Ca/Ag device based on 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) and calcium (Ca) buffer layer with improved junction properties. The I–V characteristics have been utilized to extract various electrical parameters such as ideality factor (n), barrier height (ϕ{sub B}) and series resistance R{sub s}, which are found to be 1.9, 0.79 eV and 2.5 kΩ, respectively. The device shows good rectifying behavior, with a rectification ratio of 528, and also field-lowering mechanism with a linear dependence of log I on V{sup 1/2}. The device reported in the present work shows 50% improvement in the rectification ratio and ideality factor as compared to our previously fabricated device. It appears from the experimental data that the transport mechanism in the PTCDA thin film is dominated by the Poole–Frenkel model of thermionic emission, which may be associated with high density of structural defects or traps present in the film.

    Full Text Available We have demonstrated hydrothermal synthesis of rectangular pillar-like CuO nanostructures at low temperature (~60°C by selective growth on top of NiO porous structures film deposited using chemical bath deposition method at room temperature using indium tin oxide (ITO coated glass plate as a substrate. The growth of CuO not only filled the NiO porous structures but also formed the big nanopillars/nanowalls on top of NiO surface. These nanopillars could have significant use in nanoelectronics devices or can also be used as p-type conducting wires. The present study is limited to the surface morphology studies of the thin nanostructured layers of NiO/CuO composite materials. Structural, morphological, and absorption measurement of the CuO/NiO heterojunction were studied using state-of-the-art techniques like X-ray diffraction (XRD, transmission electron microscopy (SEM, atomic force microscopy (AFM, and UV spectroscopy. The CuO nanopillars/nanowalls have the structure in order of (5 ± 1.0 μm × (2.0 ± 0.3 μm; this will help to provide efficient charge transport in between the different semiconducting layers. The energy band gap of NiO and CuO was also calculated based on UV measurements and discussed.

    The identical modulating ability between transverse electric, TE, and transverse magnetic, TM, modes is stringent condition while realizing polarization insensitive optical modulators. This in turn incorporates significant compromise in polarization sensitive loss, PSL. In this work, we propose the concept of fiber-optic polarization-insensitive optical modulator architecture that is attributed with a microscale length and low PSL. This is achieved by transferring Al/HfO2/ITO/HfO2 stack around the core region of half polished fiber that imposes equal influence on the horizontal and vertical components of propagating optical modes. Moreover, the majority of propagating optical modes is concentrated around active material region that results in compact, enhanced modulator design. The modulator is capable of offering extinction ratio as high as 23.71 dB and insertion loss as low as 1.01 dB for the TE mode. Concurrently, for TM mode are 23.93 dB and 1.07 dB. The PSL at ON-State of ∼0.056 dB ensures similar modulating ability for both TE and TM modes. The 3 dB modulating bandwidth of 45.85 GHz is realized with active length of 10 μm at the expense of 0.39 pJ/bit. The operating wavelength ranges between ∼1475 nm and ∼1625 nm with optical bandwidth excess of 150 nm.

    A metamaterial consisting of an array of gold micro-disks, separated from a ground plane of indium tin oxide (ITO) by a thin film of vanadium dioxide (VO2), behaves as a perfect absorber at infrared (IR) frequencies at room temperature. This metamaterial, which is transparent to visible light, can be switched to a highly reflecting state for IR light by heating the metamaterial to temperatures larger than the metal-insulator phase transition temperature 68°C of VO2. For a disk diameter of 1.5 μm and VO2 film thickness of 320 nm, two absorption bands are obtained: one, that arises from the metamaterial resonance; and a second peak that arises principally from a Fabry-Pérot resonance. A large change (>78%) occurs in the reflectivity between the low and high temperature phases. IR emittance of the metamaterial was measured with IR cameras and shown to be switchable to result in low emittance at high temperature. Optical readout of the state of VO2 within the metamaterial is demonstrated.

    Gallium arsenide (GaAs) thin films have been deposited on ITO-coated glass substrates from acid aqueous solution by electrodeposition technique. The structure and the morphology of the samples were analyzed by X-ray diffraction (XRD) and atomic force microscope (AFM). The optical characteristics were investigated at room temperature using a UV-Vis spectrometer. At lower deposition time, the XRD patterns exhibit a mixture of both cubic and orthorhombic GaAs phases. With further increase of the film thickness, only orthorhombic structure was observed with a preferred (100) orientation. By applying the Debye-Scherrer method, the estimated crystallite size for the (200) orientation ranged from 30 to 50 nm, whereas for the (022) orientation was found to be 13-22 nm. From the AFM measurements, the rms surface roughness ranged between 11.4 and 18.4 nm. The analysis of the optical absorption data of the annealed GaAs film deposited at different times revealed direct band gap energy in the range of 1.60-1.85 eV. The large blueshifts observed in this study can be fully explained by the Burstein-Moss effect.

    The dry etching of indium tin oxide (ITO) layers deposited on glass substrates was investigated in a high density inductively coupled plasma (ICP) source. This innovative low pressure plasma source uses a magnetic core in order to concentrate the electromagnetic energy on the plasma and thus provides for higher plasma density and better uniformity. Different gas mixtures were tested containing mainly hydrogen, argon and methane. In Ar/H{sub 2} mixtures and at constant bias voltage (-100 V), the etch rate shows a linear dependence with input power varying the same way as the ion density, which confirms the hypothesis that the etching process is mainly physical. In CH{sub 4}/H{sub 2} mixtures, the etch rate goes through a maximum for 10% CH{sub 4} indicating a participation of the radicals to the etching process. However, the etch rate remains quite low with this type of gas mixture (around 10 nm/min) because the etching mechanism appears to be competing with a deposition process. With CH{sub 4}/Ar mixtures, a similar feature appeared but the etch rate was much higher, reaching 130 nm/min at 10% of CH{sub 4} in Ar. The increase in etch rate with the addition of a small quantity of methane indicates that the physical etching process is enhanced by a chemical mechanism. The etching process was monitored by optical emission spectroscopy that appeared to be a valuable tool for endpoint detection.

    Full Text Available Nanoporous and nanostructured films, assemblies and arrangements are important from an applied point of view in microelectronics, photonics and optical materials. The ability to minimize reflection, control light output and use contrast and variation of the refractive index to modify photonic characteristics can provide routes to enhanced photonic crystal devices, omnidirectional reflectors, antireflection coatings and broadband absorbing materials. This work shows how multiscale branching of defect-free ITO NWs grown as a layer with a graded refractive index improves antireflection properties and shifts the transparency window into the near-infrared (NIR. The measurements confirm the structural quality and growth mechanism of the NW layer without any heterogeneous seeding for NW growth. Optical reflectance measurements confirm broadband antireflection down to <5% between 1.3-1.6 um which is tunable with the NW density. The work also outlines how the suppression of the Burstein-Moss shifts using refractive index variation allows transparency in a conductive NW layer into NIR range.

    The fabrication and characterization of a surface plasmon resonance based pH sensor using coatings of silver, ITO (In2O3:SnO2), aluminium and smart hydrogel layers over an unclad core of an optical fiber have been reported. The silver, aluminium and ITO layers were coated using a thermal evaporation technique, while the hydrogel layer was prepared using a dip-coating method. The sensor works on the principle of detecting changes in the refractive index of the hydrogel layer due to its swelling and shrinkage caused by changes in the pH of the fluid surrounding the hydrogel layer. The sensor utilizes a wavelength interrogation technique and operates in a particular window of low and high pH values. Increasing the pH value of the fluid causes swelling of the hydrogel layer, which decreases its refractive index and results in a shift of the resonance wavelength towards blue in the transmitted spectra. The thicknesses of the ITO and aluminium layers have been optimized to achieve the best performance of the sensor. The ITO layer increases the sensitivity while the aluminium layer increases the detection accuracy of the sensor. The proposed sensor possesses maximum sensitivity in comparison to the sensors reported in the literature. A negligible effect of ambient temperature in the range 25 °C to 45 °C on the performance of the sensor has been observed. The additional advantages of the sensor are short response time, low cost, probe miniaturization, probe re-usability and the capability of remote sensing.

    Well-aligned, high-resolution (10 nm), three-dimensional (3D) hybrid nanostructures consisting of patterned cylinders and Au islands were fabricated on ITO substrates using an ion bombardment process and a tilted deposition process. The fabricated 3D hybrid nanostructure-embedded ITO maintained its excellent electrical and optical properties after applying a surface-structuring process. The solution processable organic photovoltaic device (SP-OPV) employing a 3D hybrid nanostructure-embedded ITO as the anode displayed a 10% enhancement in the photovoltaic performance compared to the photovoltaic device prepared using a flat ITO electrode, due to the improved charge collection (extraction and transport) efficiency as well as light absorbance by the photo-active layer.

The efficiency of the solar cells significantly increases when thermal treatments are applied just after the ITO deposition. The efficiency is also dependent on the characteristics of the pyramidal relief of the silicon surface previously obtained by immersion of the Si wafers in a sodium carbonate/bicarbonate solution. An efficiency of 15.5% has been obtained with an optimized texturization of the silicon substrates and an annealing treatment of the solar cells at 400 deg. C just after the ITO deposition.

    In the present research, we propose a novel approach for the detection of hydrogen gas using Mn implanted ZnO nanowires fabricated onto ITO coated glass substrate by chemical spray pyrolysis deposition. The effect of Mn concentration on the structural, optical and morphological properties of ZnO films were investigated. X-ray diffraction studies showed that the Mn implanted ZnO films were grown as a polycrystalline hexagonal wurtzite phase without any impurities. The (101) peak position of ZnO-Mn films was shifted towards a lower angle with increasing Mn concentration. The optical band gap decreased from 3.45eV to 3.23eV with increasing Mn content. PL spectra, revealed sharp and strong near band edge emission which suggests that ZnO nanowires exhibit high crystalline quality. FE-SEM images of Mn implanted ZnO show perfectly aligned nanowires for all the films fabricated on ITO. The material (Zn, O, Mn) was confirmed by EDX spectra. The hydrogen sensing mechanism of the Mn implanted ZnO nanowire sensor was also discussed. It was found that H2 response was significantly enhanced by more than one order of magnitude with increasing Mn doping concentrations. The studied ZnO-Mn films coated on ITO substrate can be used as a low cost and easy-fabrication hydrogen sensing material. Copyright © 2017 Elsevier B.V. All rights reserved.

    The fabrication of ITO-capped WO3 nanowires associated with their bio-sensing properties in field-effect transistor diagnostics basis as a biosensor has been reported. The bio-sensing property for manipulated nanowires elucidated that the grown nanostructures were very sensitive to protein. The ITO-capped WO3 nanowires biosensor showed an intensive bio-sensing activity against reliable protein. Polylysine strongly charged bio-molecule was applied as model system to demonstrate the implementation of materialized biosensor. The employed sensing mechanism was `label-free' and depended on bio-molecule's intrinsic charge. For nanowires synthesis, the vapor-liquid-solid mechanism was used. Nanowires were beyond a few hundred nanometers in lengths and around 15-20 nm in diameter, while the globe cap's size on the nanowires was around 15-25 nm. The indium tin oxide (ITO) played as catalyst in nanofabrication for WO3 nanowires growth and had outstanding role in bio-sensing especially for bio-molecule adherence. In applied electric field presence, the fabricated device showed the great potential to enhance medical diagnostics.

    A label free, amperometric uric acid biosensor is described by immobilizing enzyme uricase through a self assembled monolayer (SAM) of 3-aminopropyltriethoxysilane (APTES) using a crosslinker, Bis[sulfosuccinimidyl]suberate (BS{sup 3}) on an indium-tin-oxide (ITO) coated glass plate. The biosensor (uricase/BS{sup 3}/APTES/ITO) was characterized by, scanning electron microscopy (SEM), atomic force microscopy (AFM) and electrochemical techniques. Chronoamperometric response was measured as a function of uric acid concentration in aqueous solution (pH 7.4). The biosensor shows a linear response over a concentration range of 0.05 to 0.58 mM with a sensitivity of 39.35 {mu}A mM{sup -1}. The response time is 50 s reaching to a 95% steady state current value and about 90% of enzyme activity is retained for about 7 weeks. These results indicate an efficient binding of enzyme with the crosslinker over the surface of APTES modified ITO glass plates, which leads to an improved sensitivity and shelf life of the biosensor.

    Full Text Available Deoxyribonucleic acid or DNA molecules expressed as double-stranded (DSS negatively charged polymer plays a significant role in electronic states of metal/silicon semiconductor structures. Electrical parameters of an Au/DNA/ITO device prepared using self-assembly method was studied by using current-voltage (I-V characteristic measurements under alpha bombardment at room temperature. The results were analyzed using conventional thermionic emission model, Cheung and Cheung's method and Norde's technique to estimate the barrier height, ideality factor, series resistance and Richardson constant of the Au/DNA/ITO structure. Besides demonstrating a strongly rectifying (diode characteristic, it was also observed that orderly fluctuations occur in various electrical parameters of the Schottky structure. Increasing alpha radiation effectively influences the series resistance, while the barrier height, ideality factor and interface state density parameters respond linearly. Barrier height determined from I-V measurements were calculated at 0.7284 eV for non-radiated, increasing to about 0.7883 eV in 0.036 Gy showing an increase for all doses. We also demonstrate the hypersensitivity phenomena effect by studying the relationship between the series resistance for the three methods, the ideality factor and low-dose radiation. Based on the results, sensitive alpha particle detectors can be realized using Au/DNA/ITO Schottky junction sensor.

    A method for obtaining transparent conductive ITO (indium-tin oxide) films aimed for use in light emitting diodes of the blue spectral range is developed. The peak external quantum efficiency of light-emitting diodes with a p-contact based on the obtained films reaches 25%, while for similar light-emitting diodes with a standard semitransparent metal contact, it is <10%. An observed increase in the direct voltage drop from 3.15 to 3.37 V does not significantly affect the possibility of applying these films in light-emitting diodes since the optical power of light-emitting diodes with a transparent p-contact based on ITO films exceeds that of chips with metal semitransparent p-contacts with a working current of 20 mA by a factor of almost 2.5. Light-emitting diodes with p-contacts based on ITO films successfully withstand a pumping current that exceeds their calculated working current by a factor of 5 without the appearance of any signs of degradation.

    The effect of a transparent ITO current spreading layer on electrical and light output properties of blue InGaN/GaN light emitting diodes (LEDs) is discussed. When finite conductivity of ITO is taken into account, unlike in previous models, the topology of LED die and contacts are shown to significantly affect current spreading and light output characteristics in top emitting devices. We propose an approach for calculating the current transfer length describing current spreading. We show that an inter-digitated electrode configuration with distance between the contact pad and the edge of p-n junction equal to transfer length in the current spreading ITO layer allows one to increase the optical area of LED chip, as compared to the physical area of the die, light output power, and therefore, the LED efficiency for a given current density. A detailed study of unpassivated LEDs also shows that current transfer lengths longer than the distance between the contact pad and the edge of p-n junction leads to increasing surface leakage that can only be remedied with proper passivation.

    A computer aid is proposed in this paper for planning paths for redundant robots. The aid, called a Path Planning Editor (PPE), allows a user to specify the complete configuration for a redundant robot over a desired path. Powerful visualization features in the PPE help the user make decisions on configuration selection for the robot. Visualization is offered not only of the robot motion but also of the optimization criterion function plotted over the redundant space. A demonstration of these ideas has been implemented using two graphic workstations for 3-D visualization and a third computer for the user interface designed using the X Window system. The robot chosen for the application is the 8 degrees of freedom AAI robot used in the Advanced Teleoperation Laboratory of JPL. Details of the implementation are described and suggestions are made for improvement of the PPE in this paper.

    I will summarize the community services provided by the AAS Journals' Data Editors to support authors’ when citing and preserving the software and data used in the published literature. In addition I will describe the life of a piece of code as it passes through the current workflows for software citation in astronomy. Using this “lifecycle” I will detail the ongoing work funded by a grant from the Alfred P. Sloan Foundation to the American Astronomical Society to improve the citation of software in the literature. The funded development team and advisory boards, made up of non-profit publishers, literature indexers, and preservation archives, is implementing the Force11 Software citation principles for astronomy Journals. The outcome of this work will be new workflows for authors and developers that fit in their current practices while enabling versioned citation of software and granular credit for its creators.

    The PEDITOR image processing system was created to be readily transferable from one type of computer system to another. While nearly identical in function and operation to its predecessor, EDITOR, PEDITOR employs additional techniques which greatly enhance its portability. These cover system structure and processing. In order to confirm the portability of the software system, two different types of computer systems running greatly differing operating systems were used as target machines. A DEC-20 computer running the TOPS-20 operating system and using a Pascal Compiler was utilized for initial code development. The remaining programmers used a Motorola Corporation 68000-based Forward Technology FT-3000 supermicrocomputer running the UNIX-based XENIX operating system and using the Silicon Valley Software Pascal compiler and the XENIX C compiler for their initial code development.

    1992-01-01

    Software development is widely considered to be a bottleneck in the development of complex systems, both in terms of development and in terms of maintenance of deployed systems. Cost of software development and maintenance can also be very high. One approach to reducing costs and relieving this bottleneck is increasing the reuse of software designs and software components. A method for achieving such reuse is a software parts composition system. Such a system consists of a language for modeling software parts and their interfaces, a catalog of existing parts, an editor for combining parts, and a code generator that takes a specification and generates code for that application in the target language. The Advanced Software Development Workstation is intended to be an expert system shell designed to provide the capabilities of a software part composition system.

    2011-01-01

    TIn the autumn of 2010 I became the Editor-in Chief of European Journal of Physics (EJP). EJP is a place for teachers, instructors and professors to exchange their views on teaching physics at university level and share their experience. It is general opinion that no good research is possible without connection with good, high-quality teaching, at the university level in particular. Therefore excellence in physics teaching is important to the physics community. European Journal of Physics is proud of its contribution to achieving this goal. As Editor-in-Chief, I will continue to work to this general objective of the journal. We will publish articles on specific topics in physics, stressing originality of presentation and suitability for use in students'laboratories, lectures and physics teaching in general. We will also publish more pedagogical papers presenting the achievements of particular teaching methods. In addition, we will continue to publish special sections on particular areas of physics, as well as the annual special section on physics competitions. European Journal of Physics is in good shape. Due to the work of the previous editors and the publisher, the readership is high and growing steadily, and many excellent papers are being submitted and published. I hope that this positive trend for the journal will continue, and I will do my best to keep to this high standard. A few words about myself. I work in the Institute of Physics in Warsaw, Poland. My main research interests are in theoretical quantum optics and I have published about 80 research papers on this topic. For many years I was involved in teaching physics at university and in high school. I am a co-author of a textbook on physics for high-school students and of a problem book in quantum mechanics. For the last ten years, I have been involved in the International Physics Olympiad and over the last few years I have been a member of the Editorial Board of European Journal of Physics.

Multi-electrode arrays (MEA) for electrical and optical characterization of biological cells were fabricated using standard MEMS technologies. Optimal sputter parameters concerning oxygen flow, sputter power and ambient pressure for ITO layers with both good optical and electrical properties were determined. Afterwards, coherent sub-20 nm wide and 150 nm deep nanocuts of many micrometers in length were generated within the ITO electrodes by a sub-15 femtosecond (fs) pulsed laser. The influence of laser processing on the electrical and optical properties of electrodes was investigated. The electrochemical impedance of the manufactured electrodes was measured before and after laser modification using electrochemical impedance spectroscopy. A small reduction in electrode impedance was observed. These nanostructured electrodes show also polarizing effects by the visible spectrum.

    Graphical abstract: - Highlights: • We report that the performance of OLED consist of aromatic small molecules with double bond carboxylic acid groups on ITO surface. • The OLED devices were tested in terms of electrical and optical characteristics. • The I–V results show that OLEDs with SAM-modified ITO surface have lower turn on voltages than OLED configurations without SAMs. - Abstract: 5-[(3-Methylphenyl)(phenyl)amino]isophthalic acid (5-MePIFA) and 5-(diphenyl)amino]isophthalic acid (5-DPIFA) organic molecules were synthesized to form self-assembled monolayer on indium tin oxide (ITO) anode to enhance hole transport from ITO to organic hole transport layers such as TPD. The modified surface was characterized by scanning tunneling microscopy (STM). The change in the surface potential was measured by Kelvin probe force microscopy (KPFM). Our Kelvin probe force microscopy (KPFM) measurements showed that the surface potentials increased more than 100 mV with reference to bare indium tin-oxide. The results show that the threshold voltage on OLEDs with modified ITO is lowered significantly compared to OLEDs with unmodified ITO. The hole mobility of TPD has been estimated using space–charge-limited current measurements (SCLC)
