内容説明
An authoritative, updated text that offers an introduction to crystals and crystal structure with coverage of crystallography, and microscopy of materials
Written 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 properties
Written 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.
