Controlled Synthesis of Nanoparticles in Microheterogeneous Systems

Because of their structural and dynamical properties, microheterogeneous systems have been employed as solvent and reaction media both to synthesize and stabilize nanoparticles. Following this route, inside their nanometer-sized heterogeneities the nanoparticles of many different substances have been incorporated. The book shows the distinct advantages of this synthetic strategy over that of many other methods. Moreover, it furnishes to the reader a collection of theoretical and experimental facts allowing him to reduce the number of trial and errors necessary to arrive at an optimal synthetic protocol.

Synthesis, Properties and Applications of Ultrananocrystalline Diamond: Proceedings of the NATO ARW on Synthesis, Properties and Applications of Ultrananocrystalline … Petersburg, Russia, from 7 to 10 June 2004.

Ultrananocrystalline diamond (UNCD) is one of the important triad of nanostructured carbons which includes fullerenes and nanotubes. This new kind of diamond composed of 3–5 nm crystallites is an exemplar par excellence of the profound changes in properties that can accompany the reduction in size of a material to low single digit nanometer dimensions. UNCD occurs in two forms: as a dispersed powder made by detonation techniques and as a chemical vapor deposited film. Two communities of scientists, each focused on one of these fields, had up to now, been working independently of each other largely unaware of the vast synergistic relationships existing between them. The NATO Advanced Research Workshop (ARW), the basis for the Proceedings, was held June 7–10 in St. Petersburg, Russia to bring the two communities closer together. Fostering collaborations between them, to hasten the exploitation of the scientific and technological treasure trove awaiting imaginative explorers to reveal the still largely untapped potential hidden in these materials.

This Proceedings volume will be of interest to a wide audience of scientists and engineers – indeed all those who wish to become familiar with the unique properties of UNCD particles and films that make them potentially very useful for a wide variety of applications. 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 on the one hand and describing progress that has been made in several areas of applications. For UNCD particles, applications include their use in nanocomposites, selective adsorbents, colloidal suspensions, microabrasives, lubricants, quantum dots, cold-cathodes and many others. For UNCD films, their smooth, highly dense, pin-hole free characteristics lead to conformal coatings of very high aspect ratio structures and applications in MEMS, biosensors, as well as electrochemical, and nerve prostheses. The films can be made both n- and p-type conducting thus enabling many potential electronic applications such as high temperature, highly rectifying diodes, FET’s, thermoelectrics, etc.

The Proceedings will be very useful 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. It is to be hoped that the wider scientific community will be as intrigued and challenged by these presentations as were the participants of the NATO ARW.

Carbon Nanotubes: Advanced Topics in the Synthesis, Structure, Properties and Applications (Topics in Applied Physics)

The carbon nanotubes field has evolved substantially since the publication of the bestseller Carbon Nanotubes: Synthesis, Structure, Properties and Applications . The present volume builds on the generic aspects of the aforementioned book, which emphasizes the fundamentals, with the new volume emphasizing areas that have grown rapidly since the first volume, guiding future directions where research is needed and highlighting applications. The volume also includes an emphasis on areas like graphene, other carbon-like and other tube-like materials because these fields are likely to affect and influence developments in nanotubes in the next 5 years.
