Book Description
Diamond-based composites, with their advantages of hardness, high Young's modulus and the like, have demonstrated new and unusual features, such as stability to high temperatures and pressure shocks and a large internal surface that can be controlled to offer customised electrical, magnetic and optical properties, leading to efficient filters, absorbents, sensors and other tools for environmental control and monitoring. The current book covers the synthesis of materials, their characterization and properties, trends in high pressure and high temperature technologies, low pressure technologies, basic principles of DBC material science, and future developments in electronics, optics, industrial tools and components, biotechnology, and medicine. Wide band-gap materials are considered, ranging from molecular clusters, nanophase materials, growth, processing and synthesis. The processing of composite based materials can be classified into six basic methods: in situ growth, high pressure/high temperature catalytic conversion; mix and sinter (c-BN plus metal-ceramic polymer mix); direct sintering; direct polymorphic conversion; shock detonation; and SHS sintering.

Book Description
Nanodiamonds offer a potential novel template for drug delivery and targeting, because of their small primary particle size, purity, excellent properties, facile surface functionalization, high biocompatibility, and inexpensive large-scale synthesis. However, nanodiamond properties such as aggregation state, surface chemistry, and presence of impurities, as well as the localization and accumulation behavior at the organism level, must be controlled to maintain safety and retain efficacy of conjugated therapeutic agents. A clinically applicable approach requires investigation of biocompatibility, biodistribution, and biological fate of the nanodiamond as well as its conjugates.

Book Description
Diamond films have been considered as ideal candidates for protective coatings on bioimplants, as bioimplants themselves or as a guide for neural differentiation, because of their excellent mechanical properties, functional amenability, biocompatibility, and unique nanostructures. We separate nanocrystalline diamond films into two categories based on growth chemistries, nanostructure, and properties: nanocrystalline diamond (NCD) and ultrananocrystalline diamond (UNCD). UNCD is suitable for application as a hermetic coating for protection of implantable artificial retina medical devices, and also contributes to improvement of neural stem cell (NSC)-based cell transplantation, tissue engineering for neural tissue repair and regeneration and study of neural cell differentiation.

Book Description
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.

Book Description
The growth of nanocrystalline diamond (NCD) thin films has become routine in labs and companies globally. This has been enabled by the fast progress of diamond nucleation and seeding in science and technology during the past decade, as a result of chemical vapour deposition (CVD) of NCD films requiring that a non-diamond substrate is treated by nucleation or seeding process prior to diamond growth. However, growth of ultrathin continuous NCD films (thickness

Book Description
With increasing numbers of orthopaedic devices being implanted, greater emphasis is being placed on ceramic coating technology to reduce friction and wear in mating total joint replacement components, in order to improve implant function and increase device lifespan. In this chapter, we consider ultra-hard carbon coatings, with emphasis on nanostructured diamond, as alternative bearing surfaces for metallic components. Such coatings have great potential for use in biomedical implants as a result of their extreme hardness, wear resistance, low friction and biocompatibility. These ultra-hard carbon coatings can be deposited by several techniques resulting in a wide variety of structures and properties.
