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).

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.

'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.
