This volume deals with the technologies of crystal fabrication, of crystal machining, and of epilayer production and is the first book on industrial and scientific aspects of crystal and layer production. The major industrial crystals are treated: Si, GaAs, GaP, InP, CdTe, sapphire, oxide and halide scintillator crystals, crystals for optical, piezoelectric and microwave applications and more. Contains 29 contributions from leading crystal technologists covering the following topics: * General aspects of crystal growth technology * Silicon * Compound semiconductors * Oxides and halides * Crystal machining * Epitaxy and layer deposition Scientific and technological problems of production and machining of industrial crystals are discussed by top experts, most of them from the major growth industries and crystal growth centers. In addition, it will be useful for the users of crystals, for teachers and graduate students in materials sciences, in electronic and other functional materials, chemical and metallurgical engineering, micro-and optoelectronics including nanotechnology, mechanical engineering and precision-machining, microtechnology, and in solid-state sciences.
Recently, there has been a major shift in the focus of historical research on World War II towards the study of the involvements of scholars and academic institutions in the crimes of the Third Reich. The roots of this involvement go back to the 1920s. At that time right-wing scholars participated in the movement to revise the Versailles Treaty and to create a new German national identity. The contribution of geopolitics to this development is notorious. But there were also the disciplines of history, geography, ethnography, art history, archeology, sociology, and demography that devised a new nationalist ideology and propaganda. Its scholars established an extensive network of personal and ...
Over recent years there has been marked growth in interest in the study of techniques of cosmic ray physics by astrophysicists and particle physicists. Cosmic radiation is important for the astrophysicist because in the farther reaches of the universe. For particle physicists, it provides the opportunity to study neutrinos and very high energy particles of galactic origin. More importantly, cosmic rays constitue the background, and in some cases possibly the signal, for the more exotic unconfirmed hypothesized particles such as monopoles and sparticles. Concentrating on the highest energy cosmic rays, this book describes where they originate, acquire energy, and interact, in accreting neutron stars, supernova remnants, in large-scale shock waves. It also describes their interactions in the atmosphere and in the earth, how they are studied in surface and very large underground detectors, and what they tell us.
Overall recent research on TLRs has led to tremendous increase in our understanding of early steps in pathogen recognition and will presumably lead to potent TLR targeting therapeutics in the future. This book reviews and highlights our recent understanding on the function and ligands of TLRs as well as their role in autoimmunity, dendritic cell activation and target structures for therapeutic intervention.

Dusty Plasmas Physics, Chemistry and Technological Impacts in Plasma Processing Edited by André Bouchoule Université d'Orléans, France Dusty Plasmas gives the reader a thorough overview of current knowledge on many aspects of the subject, from the basic science to technological implications. The basic physics and chemistry of dusty plasmas developed in the first two chapters are complemented by the more practical considerations of diagnostics and technological implications in the two final chapters. The book will be of interest to those already involved in or just discovering dusty plasmas in their research and/or industrial activity. * Physics and Modelling of Dusty Plasmas * Sources and Growth of Particles * Diagnostics of a Dusty Plasma * Technological Impacts of Dusty Plasmas
There are only few discoveries and new technologies in physical sciences that have the potential to dramatically alter and revolutionize our electronic world. Topological insulators are one of them. The present book for the first time provides a full overview and in-depth knowledge about this hot topic in materials science and condensed matter physics. Techniques such as angle-resolved photoemission spectrometry (ARPES), advanced solid-state Nuclear Magnetic Resonance (NMR) or scanning-tunnel microscopy (STM) together with key principles of topological insulators such as spin-locked electronic states, the Dirac point, quantum Hall effects and Majorana fermions are illuminated in individual chapters and are described in a clear and logical form. Written by an international team of experts, many of them directly involved in the very first discovery of topological insulators, the book provides the readers with the knowledge they need to understand the electronic behavior of these unique materials. Being more than a reference work, this book is essential for newcomers and advanced researchers working in the field of topological insulators.
This is a story of the unexpected.In Destined to Witness, Hans Massaquoi has crafted a beautifully rendered memoir -- an astonishing true tale of how he came of age as a black child in Nazi Germany. The son of a prominent African and a German nurse, Hans remained behind with his mother when Hitler came to power, due to concerns about his fragile health, after his father returned to Liberia. Like other German boys, Hans went to school; like other German boys, he swiftly fell under the Fuhrer's spell. So he was crushed to learn that, as a black child, he was ineligible for the Hitler Youth. His path to a secondary education and an eventual profession was blocked. He now lived in fear that, at any moment, he might hear the Gestapo banging on the door -- or Allied bombs falling on his home. Ironic, moving, and deeply human, Massaquoi's account of this lonely struggle for survival brims with courage and intelligence.
