Crystals and Crystal Structures

Informationen zum Autor RICHARD J. D. TILLEY D. Sc, Ph. D, is Emeritus Professor in the School of Engineering at the University of Cardiff, Wales, U.K. He has published extensively in the area of solid-state materials science, including nine textbooks (translated into multiple languages), 23 chapters and encyclopedia entries and more than 200 journal papers. Klappentext An authoritative, updated text that offers an introduction to crystals and crystal structure with coverage of crystallography, and microscopy of materialsWritten in a friendly, non-mathematical style, the updated second edition of Crystals and Crystal Structures offers a comprehensive exploration of the key elements of crystals and crystal structures. Starting with the basics, it includes information on multiple areas of crystallography, including modulated structures, quasicrystals and protein crystallography, and interdisciplinary applications as diverse as the relationship between physical properties and symmetry.To enhance comprehension of the material presented, the book contains a variety of problems and exercises. The revised second edition offers new material and updates in the field including:* An introduction to the use of high intensity X-ray analysis of protein structures* Advances in imaging, scanning electron microscopy, and cryo-electron microscopy* The relationship between symmetry and physical properties highlighting new findings and an introduction to tensor notation in describing these relationships in a concise fashion* Nanoparticles as well as crystallographic aspects, defects, surface defects and the impact of these crystallographic features on properties* Perovskite structures and their variations and the inclusion of their wide-ranging propertiesWritten for students ofcrystallography, chemistry, physics, materials science, biosciences and geology, Crystals and Crystal Structures, Second Edition provides an understanding of the subject and enables students to read scientific papers and articles describing a crystal structure or use crystallographic databases.
