Nanocrystalline materials are three-dimensional ultrafine, polycrystalline microstructures. They give rise to interesting and useful chemical and physical-size effects. This book describes the development of a method of synthesizing chemical vapor for the production of nanocrystalline ceramic powders. The development of the microstructure during sintering is studied and the influence of the synthesis parameters on the structure and properties of the nanocrystalline ceramics from the atomic to the microstructural level is investigated. The emerging unified view, from powder synthesis and ceramic processing to structural characterization and determination of properties, provides a detailed understanding of the materials and enables better quality control of the end products.
Gasphase synthesis of nanoparticles and nanostructured materials offers high chemical purity and crystalline quality as well as scalability up to industrial quantities. It is therefore highly attractive for both basic and applied science. This book gives a broad and coherent overview of the complete production and value chain from nanoparticle formation to integration into products and devices. Written by experts in the field – with backgrounds in electrical engineering, experimental and theoretical physics, materials science, and chemical engineering – the book offers a deep insight into the fabrication, characterization and application of nanoparticles from the gasphase. The first part...
Timely information on scientific and engineering developments occurring in laboratories around the world provides critical input to maintaining the economic and technological strength of the United States. Moreover, sharing this information quickly with other countries can greatly enhance the productivity of scientists and engineers. These are some of the reasons why the National Science Foundation (NSF) has been involved in funding science and technology assessments comparing the United States and foreign countries since the early 1980s. A substantial number of these studies have been conducted by the World Technology Evaluation Center (WTEC) managed by Loyola College through a cooperative ...
This volume entitled Advanced Science and Technology of Sintering, contains the edited Proceedings of the Ninth World Round Table Conference on Sintering (IX WRTCS), held in Belgrade, Yugoslavia, September 1-4 1998. The gathering was one in a series of World Round Table Conferences on Sintering organised every four years by the Serbian Academy of Sciences and Arts (SASA) and the International Institute for the Science of Sintering (IISS). The World Round Table Conferences on Sintering have been traditionally held in Yugoslavia. The first meeting was organised in Herceg Novi in 1969 and since then they have regularly gathered the scientific elite in the science of sintering. It is not by chan...
X-ray absorption spectroscopy and X-ray emission spectroscopy are complementary to crystallographic methods, particularly for materials science and the study of nanostructure and systems with partial disorder and partial local order, including solutions, gases, liquids, glasses and powders. This new volume of International Tables for Crystallography has nine parts and over 150 chapters contributed by a wide range of international experts. Part 1 provides a brief overview and introduction to the background of X-ray absorption spectroscopy (XAS) and experimental facilities. Part 2 discusses the quantum theory of XAS and related approaches. Part 3 describes both standard and advanced experiment...
The production of nanopowders, and their applications in industrial and technological innovation, is an important and growing area of interest in the world of nanotechnology. It is widely recognized that the basic properties of nanopowders are strongly influenced by their shape, size, distribution and surface chemistry.
