An excellent book for professional crystallographers! In 2012 the crystallographic community celebrated 100 years of X-ray diffraction in honour of the pioneering experiment in 1912 by Max von Laue, Friedrich and Knipping. Experimental developments e.g. brilliant X-ray sources, area detection, and developments in computer hardware and software have led to increasing applications in X-ray analysis. This completely revised edition is a guide for practical work in X-ray analysis. An introduction to basic crystallography moves quickly to a practical and experimental treatment of structure analysis. Emphasis is placed on understanding results and avoiding pitfalls. Essential reading for researchers from the student to the professional level interested in understanding the structure of molecules.

The study of solids is one of the richest, most exciting, and most successful branches of physics. While the subject of solid state physics is often viewed as dry and tedious this new book presents the topic instead as an exciting exposition of fundamental principles and great intellectual breakthroughs. Beginning with a discussion of how the study of heat capacity of solids ushered in the quantum revolution, the author presents the key ideas of the field while emphasizing the deep underlying concepts. The book begins with a discussion of the Einstein/Debye model of specific heat, and the Drude/Sommerfeld theories of electrons in solids, which can all be understood without reference to any underlying crystal structure. The failures of these theories force a more serious investigation of microscopics. Many of the key ideas about waves in solids are then introduced using one dimensional models in order to convey concepts without getting bogged down with details. Only then does the book turn to consider real materials. Chemical bonding is introduced and then atoms can be bonded together to crystal structures and reciprocal space results. Diffraction experiments, as the central application of these ideas, are discussed in great detail. From there, the connection is made to electron wave diffraction in solids and how it results in electronic band structure. The natural culmination of this thread is the triumph of semiconductor physics and devices. The final section of the book considers magnetism in order to discuss a range of deeper concepts. The failures of band theory due to electron interaction, spontaneous magnetic orders, and mean field theories are presented well. Finally, the book gives a brief exposition of the Hubbard model that undergraduates can understand. The book presents all of this material in a clear fashion, dense with explanatory or just plain entertaining footnotes. This may be the best introductory book for learning solid state physics. It is certainly the most fun to read.

Plasticity of crystals in a microscopic viewpoint, especially on the basis of dislocation (linear defects in crystal) motion, is detailed from the data obtained mainly by the strain-rate cycling tests associated with ultrasonic oscillation for several kinds of alkali-halide single crystals at low temperatures. Topics discussed include process for thermal activated overcoming of the short-range obstacle by a dislocation; strain-rate cycling tests associated with ultrasonic oscillation; influence of state of impurities on the effective stress due to the impurities; effective stress and critical temperature of KCl doped with various divalent cations; and the Friedel relation and thermally activated flow parameters of KCl doped with various divalent cations.

Neutron scattering is arguably the most powerful technique available for looking inside materials and seeing what the atoms are doing. This textbook provides a comprehensive and up-to-date account of the many different ways neutrons are being used to investigate the behaviour of atoms and molecules in bulk matter. It is written in a pedagogical style, and includes many examples and exercises. Every year, thousands of experiments are performed at neutron scattering facilities around the world, exploring phenomena in physics, chemistry, materials science, as well as in interdisciplinary areas such as biology, materials engineering, and cultural heritage. This book fulfils a need for a modern and pedagogical treatment of the principles behind the various different neutron techniques, in order to provide scientists with the essential formal tools to design their experiments and interpret the results. The book will be of particular interest to researchers using neutrons to study the atomic-scale structure and dynamics in crystalline solids, simple liquids and molecular fluids by diffraction techniques, including small-angle scattering and reflectometry, and by spectroscopic methods, ranging from conventional techniques for inelastic and quasielastic scattering to neutron spin-echo and Compton scattering. A comprehensive treatment of magnetic neutron scattering is given, including the many and diverse applications of polarized neutrons.

The science of the arrangement of atoms in solids is known as crystallography. In single crystals, the effects of the crystalline arrangement of atoms is often easy to see macroscopically, because the natural shapes of crystals reflect the atomic structure. In addition, physical properties are often controlled by crystalline defects. The understanding of crystal structures is an important prerequisite for understanding crystallographic defects. Topics discussed in this new book include in situ protein crystal diffraction screening; structures and properties of 3D-4F and 3D chiral Schiff base complexes; crystal dehydration techniques; case studies on crystal structure determination involving H atoms; and cleavage fracture crystallography.

Discrete Element Methods (DEM) is a numerical technique for analysing the mechanics and physics of particulate systems. Originated in the late seventies for analysing geotechnical problems, it has seen significant development and is now employed extensively across disciplines. Produced in celebration of the 70th Birthday of Colin Thornton, this book contains a selection of papers concerning advances in discrete element modelling which were presented at the International Symposium on Discrete Element Modelling of Particulate Media held at Birmingham, UK on 28-30th March, 2012. The book showcases the wide application of discrete element modelling in gas-solid fluidisation, particulate flows, liquid-solid systems and quasi-static behaviour. It also reports the recent advancement in coupled DEM with computational fluid dynamics, Lattice Boltzmann Methods for multiphase systems and the novel application of DEM in contact electrification and fracture of granular systems. Aimed at research communities dealing with this technique in the powder handling and formulation industries, this will be a welcomed addition to the literature in this area.

This book is important because it is the first textbook in an area that has become very popular in recent times. There are around 250 research groups in crystal engineering worldwide today. The subject has been researched for around 40 years but there is still no textbook at the level of senior undergraduates and beginning PhD students. This book is expected to fill this gap.

The writing style is simple, with an adequate number of exercises and problems, and the diagrams are easy to understand. This book consists major areas of the subject, including organic crystals and co-ordination polymers, and can easily form the basis of a 30 to 40 lecture course for senior undergraduates.

The International Edition of Introduction to Optical Mineralogy provides comprehensive coverage of the optical properties of minerals. It describes in detail more than 125 common rock-forming minerals and a selection of ore minerals. Revised chapters on optical theory discuss the petrographic microscope, the nature and properties of light, the behaviour of light in isotropic and anisotropic materials, and uniaxial and biaxial anisotropic optics.

Protein crystallography has become vital to further understanding the structure and function of many complex biological systems. In recent years, structure determination has progressed tremendously however the quality of crystals and data sets can prevent the best results from being obtained. With contributions from world leading researchers whose software are used worldwide, this book provides a coherent approach on how to handle difficult crystallographic data and how to assess its quality. The chapters will cover all key aspects of protein crystallography, from instrumentation and data processing through to model building. This book also addresses challenges that protein crystallographers will face such as dealing with data from microcrystals and multi protein complexes. This book is ideal for both academics and researchers in industry looking for a comprehensive guide to protein crystallography.

Crystallography can be studied from two different view-points: one as a mathematical science with its applications both in the instrumental determination of crystal angles and in their mapping or projection; the other chiefly as an observational study with the application of some simple rules that will enable the student to determine the crystalline form with sufficient accuracy for practical purposes in the field or the laboratory. This book concerns itself with the latter, author presenting his notes in the form of lectures given in the Pennsylvania State College for the use of students. A fascinating and comprehensive treatise on the subject, this rare book will greatly appeal to those with a serious interest in Crystallography. This book has been elected for modern republication due to its immense educational value, and is proudly republished here with a new introduction to the subject.

Plaiting and braiding have a long history. They encompass decorating hair, weaving and basket-making as well as making knots. So it is surprising that John Gorham seems to have been the first person to have looked at the subject systematically. The main part of this book is a reprint of his 1888 work on plaiting crystal models has been an inspiration to many others working in this field, notably Robert Pargeter and Jean Pedersen. Along with Robert Pargeter and James Brunton's articles in the Mathematical Gazette Gorham's work is here reproduced. The ideas were extensively covered in Mathematical Models by Cundy and Rollett, also reprinted by Tarquin. It is through this book and Pargeter's article that Gorham's techniques have been kept alive. The book itself has been rare and most references to it are only as a result of Pargeter having quoted it as his source. Through this reprint the work can be more widely read and admired by mathematicians, plaiters and crystallographers, as well as historians of science and mathematics.

The question of what is matter has fascinated the human race for thousands of years, and continues to fascinate us today: what is it made of, and how does it behave? Early in our history, the character of natural materials was of critical importance to us, and it is no accident that we date the prehistory of humanity by the materials with which our predecessors made their tools. Tools are one of the more enduring creations of our prehistoric ancestors, and are of particular historical significance as they document the increasing technological sophistication of the human race. From the Stone Age to the Bronze Age to the Iron Age, there was an increasing awareness of the diversity of natural materials, how they could be used, and eventually, how they could be processed in order to provide even more technologically effective materials for our use. This increasing reliance on rocks and minerals required that more and more people be conversant with these materials and their properties. The atomistic theory of the Greeks was a solely philosophical construct, and further development had to await a more sophisticated approach to Science. The first steps in this direction were taken by who else but Isaac Newton (1643-1727 AD). Although his ideas on action at a distance initially referred to planets, he also considered them as applying to atoms, and concluded from physical evidence involving surface tension and viscosity that there must be strong attractions between atoms. In what must be considered as insight of legendary proportions, Roger Joseph Boscovich (1711-1787), a Jesuit mathematician from Croatia, proposed that at very short distances, atoms repulse each other, the repulsion increasing indefinitely as the particles become closer together, whereas at longer distances apart, atoms oscillate between attraction and repulsion. Frank Hawthorne uses the republication of this set of landmark papers as a vehicle to focus on the development of key issues concerning structural connectivity in inorganic solids, of which minerals are a key component, and to look at where we are today in our understanding of crystal structure.

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. Highest-quality crystals and epitaxical layers form the base for many of industries technological advances, including telecommunication, computer and electric energy technology, and those technologies based on lasers and nonlinear-optic crystals. Furthermore, automobile electronics, audiovisual equipment and infrared night-vision all depend on high-quality crystals and epilayers, as do novel technologies currently in development and planned for the future.

This book contains 29 contributions of 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 the m from the major growth industries and crystal growth centres.

It is anticipated that this volume will serve all scientists and engineers involved in crystal and epilayer fabrication. 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. Also consultants and specialists will profit from this book, as will those interested in crystals, epilayers, and their productionfor saving energy (GaN- and SiC-based high-power electronics and light-emitting diodes for illumination) and for renewable energy sources (economic high-efficiency solar cells and forthcoming laser-fusion energy).

This book is designed to help those with little or no background in the field of defect chemistry to apply its principles and to interpret the related behaviour of materials. It is the product of a course for advanced undergraduates and graduate students that the author taught at Lehigh University for over twenty years. The course is highly interdisciplinary and has been attended by students from the departments of chemical engineering, chemistry, electrical engineering, computer science, geology, materials science and engineering, and physics. The book is intended for use either as a text on such a course, or as a reference work that covers the major principles of defect chemistry.

This classic text of elementary dislocation theory has been reprinted to fulfil persistent demand. Yet because it approaches elementary dislocation theory from its most basic level, the material contained in the volume is as up-to-date as when first published. The text addresses topics which are fundamental to the theory of dislocation behaviour, such as Burgers vectors and internal stresses of dislocations.

Concise, logical, and mathematically rigorous, this introduction to the theory of dislocations is addressed primarily to students and researchers in the general areas of mechanics and applied mathematics. Its scope encompasses those aspects of dislocation theory which are closely related to the theories of elasticity and macroscopic plasticity, to modern continuum mechanics, and to the theory of cracks and fracture. The volume incorporates several new and original pieces of work, including a development of the theory of dislocation motion and plastic strain for non-linear materials, a new discussion of the line tension model, revised calculations of the Peierls resistance, and a new development of the van der Merwe theory of crystal interfaces.

Dieses Buch fuhrt in die Mathematik der Kristallographie ein. Reihenfolge und Inhalte entsprechen dabei den ublichen Basiskursen in systematischer Mineralogie bzw. Kristallographie - im Gegensatz zu diesen Kursen legt das Buch den Fokus aber konsequent auf die mathematische Betrachtung, Erklarung und Begrundung. Das Buch bildet somit eine Brucke zwischen rein kristallographischer und rein mathematischer Literatur: Mathematiker finden hier wirklichkeitsnahe Anwendungen von analytischer Geometrie und linearer Algebra, Gruppentheorie und Projektionen. Kristallographen, Chemiker, Geologen, Mineralogen und Physiker erhalten mathematische Hintergrundinformationen und Erklarungen zu den bekannten Regeln aus der Kristallographie und Mineralogie. Alle Prinzipien werden durch konkrete Beispiele illustriert und das Gelernte kann durch UEbungsaufgaben gefestigt werden. Die Inhalte sind Studierenden schon in den ersten Studienjahren zuganglich. Der Inhalt Geometrische Darstellung (spharische, stereografische, gnomonische Projektion) Analytische Geometrie von Kristallstrukturen (etwa direktes und reziprokes Gitter) Kristallographische Gruppentheorie (etwa Punkt- und Raumgruppen)

Peter Gross stellt die Synthesen und Kristallzucht der ersten teils protonierten Alkalimetall-Borosulfate sowie Erdalkalimetall-Borosulfate beispielhaft fur Kalium- und Bariumverbindungen vor. Er erlautert praktische Aspekte der anspruchsvollen Probenpraparation, Strukturaufklarung und Bestimmung der Reinheit. Der Autor diskutiert anschliessend die Ergebnisse, systematisiert und ordnet die Verbindungen in die Systematik silicatanaloger Verbindungen ein, um die einzigartige Stellung dieser neuen Materialklasse zu illustrieren. Eine Machbarkeitsstudie zeigt als eine der vielfaltigen Anwendungsfelder den Einsatz von Borosulfaten als Wirtsstruktur fur Leuchtstoffe.

Liquid crystals (LCs) were discovered over a century ago, but their profound impact was in the past four decades through their successful implementation into electronic devices that we are using every day. The research on liquid crystals actively continues in the 21st century and offers unlimited potential in various display or non-display applications. This book covers novel topics related to LCs and is intended for a wide range of researchers in both, academia and industry, from beginners to advanced level professionals in many scientific areas, viz. materials science and engineering, chemistry, physics, optics, photonics, nanotechnology, electrical engineering, and so on. The book contains topics on nematic and cholesteric LCs, in the form of films or particles, as well as modified LC behaviour with variety of dopants, micron and nano-sized particles, microencapsulation of LC particles and modelling of their behaviour under an externally applied field. Topics related to the effect on nanomaterials on LC behaviour, as well as structural and magnetic properties of different types of iron-containing liquid crystals (metallo-mesogens) are covered, as well. Finally, an overview of different alignment technologies for nematic liquid crystals such as mechanical rubbing of polymer films, obliquely-deposited inorganic films, photo-irradiated, IB-bombarded and patterned surfaces, are briefly reviewed along with several novel alignment concepts. The state of the art in respective fields related to LCs in each chapter is given by leading experts.

Since the discovery of the first liquid crystal in 1888 by the Austrian biologist Friedrich Reinitzer with the considerable assistance of the German physicist Otto Lehman, who in that time had been universally recognised authority in the field of microscope technique, thousands and thousands of liquid crystals have been synthesised among them nematics, short-pitch cholesterics and various kinds of smectics such as smectic-A and smectic-C. The smectic-A or smectic-C phases grow from a nematic or unwinded large-pitch cholesteric oriented in the middle part of the cells and from strongly-deformed nematic or unwinded large-pitch cholesteric layer in the boundary regions of the liquid crystal cells.
