Available in PDF, EPUB and Kindle. Book excerpt: Crystals of high chemical and mechanical perfection are required for research in electronic devices. The purpose of the research reported here was to produce diamonds for use in the fabrication of semiconducting devices. This was one portion of a laboratory-wide program investigating the utilization of diamond as a high temperature semiconductor. Diamond synthesis is explained in terms of crystallization from a super-saturated liquid. The major driving force is thermodynamic. The primary condition for synthesis is a stable diamond-liquid equilibrium in which the liquid is composed of carbon and certain metal solvents. Thermodynamic expressions are developed for describing the pertinent portions of the nickel-, cobalt-, manganese-, and iron-carbon binary systems. Temperature-composition diagrams at high pressures are drawn to show stability relationships and the allowed limits for synthesis. The theoretical model is verified by an extensive ultrah-high pressure-temperature experimental investigation. Theoretical and empirical results are employed in predicting conditions for producing high quality single crystals. (Author).

Download or read book Fluorescent Nanodiamonds written by Huan-Cheng Chang and published by John Wiley & Sons. This book was released on 2018-11-12 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most comprehensive reference on fluorescent nanodiamond physical and chemical properties and contemporary applications Fluorescent nanodiamonds (FNDs) have drawn a great deal of attention over the past several years, and their applications and development potential are proving to be manifold and vast. The first and only book of its kind, Fluorescent Nanodiamonds is a comprehensive guide to the basic science and technical information needed to fully understand the fundamentals of FNDs and their potential applications across an array of domains. In demonstrating the importance of FNDs in biological applications, the authors bring together all relevant chemistry, physics, materials science and biology. Nanodiamonds are produced by powerful cataclysmic events such as explosions, volcanic eruptions and meteorite impacts. They also can be created in the lab by high-pressure high-temperature treatment of graphite or detonating an explosive in a reactor vessel. A single imperfection can give a nanodiamond a specific, isolated color center which allows it to function as a single, trapped atom. Much smaller than the thickness of a human hair, a nanodiamond can have a huge surface area that allows it to bond with a variety of other materials. Because of their non-toxicity, nanodiamonds may be useful in biomedical applications, such as drug delivery and gene therapy. The most comprehensive reference on a topic of rapidly increasing interest among academic and industrial researchers across an array of fields Includes numerous case studies and practical examples from many areas of research and industrial applications, as well as fascinating and instructive historical perspectives Each chapter addresses, in-depth, a single integral topic including the fundamental properties, synthesis, mechanisms and functionalisation of FNDs The first book published by the key patent holder with his research group in the field of FNDs Fluorescent Nanodiamonds is an important working resource for a broad range of scientists and engineers in industry and academia. It will also be a welcome reference for instructors in chemistry, physics, materials science, biology and related fields.

Download or read book Synthesis Properties and Applications of Ultrananocrystalline Diamond written by Dieter M. Gruen and published by Springer Science & Business Media. This book was released on 2005-04-13 with total page 420 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrananocrystalline diamond (UNCD) is one of the important members of the triad of nanostructured carbons, which includes fullerenes and nanotubes. UNCD with characteristic sizes of primary particles less than 10 nm occurs in two forms: as a dispersed powder made by detonation techniques and as a chemical vapor deposited film. This book for the first time combines results of research pursued by the two communities of scientists, which up to now, have been working rather independently and largely unaware of the vast synergistic relationships existing between them. It is particularly noteworthy that much of the Russian work on disperse UNCD is available here in English for the first time. The outstanding experts in the two fields are represented in this volume discussing the basic theoretical concepts underlying the synthesis and characterization of these nanomaterials and describing progress that has been made in several areas of applications such as nanocomposites, selective adsorbents, colloidal suspensions, microabrasives, lubricants, quantum dots, cold-cathodes for UNCD particles and MEMS, biosensors, electrochemical, and nerve prostheses, high temperature, highly rectifying diodes, FET’s, thermoelectrics for UNCD films. This Proceedings volume will be of interest to a wide audience of scientists and engineers and serve as an introduction to an important and rapidly evolving field of nanoscience and nanomaterials; as a text for a special topics graduate course; or as a starting point for those interested in the development of new approaches to problems that have hitherto defied solution for lack of suitable materials.
Download or read book The Diamond Makers written by Robert M. Hazen and published by Cambridge University Press. This book was released on 1999-07-22 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Humans have treasured diamonds for their exquisite beauty and unrivaled hardness for thousands of years. Deep within the earth, diamonds grow. Diamonds the size of footballs, the size of watermelons - billions of tons of diamonds wait for eternity a hundred miles beyond our reach. Spanning centuries of ground-breaking science, bitter rivalry, outright fraud, and self-delusion, The Diamond Makers is a compelling narrative centered around the brilliant, often eccentric, and controversial pioneers of high pressure research. This vivid blend of dramatic personal stories and extraordinary scientific advances - and devastating failures - brings alive the quest to create diamond. Scientists have harnessed crushing pressures and scorching temperatures to transform almost any carbon-rich material, from road tar to peanut butter, into the most prized of gems. The book reveals the human dimensions of research - the competition, bravery, jealousy, teamwork, and greed that ultimately led to today's billion-dollar diamond synthesis industry.
Download or read book Genuine Fakes written by Lydia Pyne and published by Bloomsbury Publishing. This book was released on 2019-08-08 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Lively, thought-provoking and consistently surprising. Lydia Pyne is the real deal.' Ed Yong, author of New York Times bestseller I Contain Multitudes Does an authentic Andy Warhol painting need to be painted by Andy Warhol? Why do audiences feel outraged when they find out that scenes from their beloved blockbuster documentaries are staged? Can people move past assuming that a diamond grown in a lab is a fake? What happens when a forged painting or manuscript becomes more valuable than its original? This is a book about genuine fakes – the curious and complex objects that provoke these very sorts of questions. Genuine fakes fall into the space between things that are real and things that are not; whether or not we think that those things are authentic is a matter of perspective. Unsurprisingly, the world is full of genuine fakes – full of things that defy simple categorisation. From stories of audacious forgeries to feats of technological innovation, historian Lydia Pyne explores how the authenticity of eight genuine fakes depends on their unique combinations of history, science and culture. The stories of art forgeries, fake fossils, nature documentaries, synthetic flavours, museum exhibits, Maya codices and Palaeolithic replicas show that genuine fakes are both complicated and change over time. Drawing from historical archives, interviews, museum exhibits and science fiction as well as her own research, Pyne brings each genuine fake to life through unexpected and often outrageous stories. Genuine Fakes will make readers think about all the unreal things they encounter in their daily lives, and why they invoke the reactions – surprise, wonder, understanding or annoyance – that they do.
Download or read book Genesis of Diamonds and Associated Phases written by Yuriy A. Litvin and published by Springer. This book was released on 2017-05-17 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an overview of recent advances in our understanding of the genesis of diamonds and the associated phases. It is divided into three main parts, starting with an introduction to the analysis of diamond inclusions to infer the formation processes. In turn, the second part of the book presents high-pressure experimental studies in mantle diamond-parental mineral systems with representative multicomponent boundary compositions. The experimental syngenesis phase diagrams provided reveal the physicochemical mechanisms of diamond nucleation and substantiate the mantle-carbonatite concept of the genesis of diamonds and associated phases. Lastly, the book describes the genetic classification of diamond-hosted mineral inclusions and experimentally determined RE “mineral-parental melt” partition coefficients. The physicochemical experimental evidence presented shows the driving forces behind the fractional evolution of the mantle magmas and diamond-parental melts. Given the depth and breadth of its coverage, the book offers researchers essential new insights into the ways diamonds and associated minerals and rocks are naturally created.
Download or read book Diamond Electronic Properties and Applications written by Lawrence S. Pan and published by Springer Science & Business Media. This book was released on 1994-12-31 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of diamond for electronic applications is not a new idea. As early as the 1920's diamonds were considered for their use as photoconductive detectors. However limitations in size and control of properties naturally limited the use of diamond to a few specialty applications. With the development of diamond synthesis from the vapor phase has come a more serious interest in developing diamond-based electronic devices. A unique combination of extreme properties makes diamond partiCularly well suited for high speed, high power, and high temperature applications. Vapor phase deposition of diamond allows large area films to be deposited, whose properties can potentially be controlled. Since the process of diamond synthesis was first realized, great progress have been made in understanding the issues important for growing diamond and fabricating electronic devices. The quality of both intrinsic and doped diamond has improved greatly to the point that viable applications are being developed. Our understanding of the properties and limitations has also improved greatly. While a number of excellent references review the general properties of diamond, this volume summarizes the great deal of literature related only to electronic properties and applications of diamond. We concentrate only on diamond; related materials such as diamond-like carbon (DLC) and other wide bandgap semiconductors are not treated here. In the first chapter Profs. C. Y. Fong and B. M. Klein discuss the band structure of single-crystal diamond and its relation to electronic properties.
