Bibliography 1974–75 Organic and Organometallic Crystal Structures


Book Description

This volume is the seventh classified bibliography of organic and organometallic crystal structures prepared by the Crystallographic Data Centre, University Chemical Laboratory, Cambridge, and published jointly with the International Union of Crystallography. The first six volumes covered the years 1935-1974. The present volume provides references principally to compounds whose struc tures were reported in the literature during 1974-1975. A few structures published prior to 1974 and omitted from the previous volumes are also included. There are three cumulative indexes in the present volume: formula, transition metal and author indexes. All three cover the period 1935- 1975 and give references to entries in Vols. 1-7. The bibliography and indexes were prepared, checked and printed by computer techniques described in the previous volumes. Magnetic tapes of the seven volumes are available and anyone interested should contact the Centre for further details. In the present volume we have continued the special arrangement for literature search with the Centre National de Ia Recherche Scientifique, Paris, France. Under this arrangement reprints of papers containing crystallographic data are sent directly to the Crystal lographic Data Centre, Cambridge, at the same time as they are sent out to abstractors preparing material for the Bulletin Signaletique.







Bibliography 1975–76 Organic and Organometallic Crystal Structures


Book Description

This volume is the eighth classified bibliography of organic and organometallic crystal structures prepared by the Crystallographic Data Centre, University Chemical Laboratory, Cambridge, and published jointly with the International Union of Crystallography. The first seven volumes covered the years 1935-1975. The present volume provides references principally to compounds whose struc tures were reported in the literature during 1975-1976. A few structures published prior to 1975 and omitted from the previous volumes are also included. This volume incorporates some major changes in methods of preparation, indexing, and literature coverage. These changes are designed to give a later cut-off date for the literature coverage, and to make the main classified listing more accessible to the reader through improved indexing. The major technical change was the use of the FR80 microfilm recorder at the Science Research Council Rutherford Laboratory, instead of the Linotron 505 filmsetter, to prepare the master copy of the book. The change necessitated the development of a new set of prQgrams, a project carried out in collaboration with the Atlas Computing Division of the Rutherford Laboratory. The reader may also notice the use of a new type font, developed by Dr A. V. Hershey and made available by Mrs Carla Messina, Dr N. M. Wolcott and Mr J. Hilsenrath of the USA National Bureau of Standards.




Crystallography and Crystal Defects


Book Description

Crystallography and Crystal Defects Revised Edition A. Kelly, Churchill College, Cambridge, UK G. W. Groves, Exeter College, Oxford, UK and P. Kidd, Queen Mary and Westfield College, University of London, UK The concepts of crystallography are introduced here in such a way that the physical properties of crystals, including their mechanical behaviour, can be better understood and quantified. A unique approach to the treatment of crystals and their defects is taken in that the often separate disciplines of crystallography, tensor analysis, elasticity and dislocation theory are combined in such a way as to equip materials scientists with knowledge of all the basic principles required to interpret data from their experiments. This is a revised and updated version of the widely acclaimed book by Kelly and Groves that was first published nearly thirty years ago. The material remains timely and relevant and the first edition still holds an unrivalled position at the core of the teaching of crystallography and crystal defects today. Undergraduate readers will acquire a rigorous grounding, from first principles, in the crystal classes and the concept of a lattice and its defects and their descriptions using vectors. Researchers will find here all the theorems of crystal structure upon which to base their work and the equations necessary for calculating interplanar spacings, transformation of indices and manipulations involving the stereographic projection and transformations of tensors and matrices.




Bibliography 1971–72 Organic and Organometallic Crystal Structures


Book Description

This volume is the fourth c1assified bibliography of organic and organometallic crystal structures prepared by the Crystallographic Data Centre, University Chemical Laboratory, Cambridge, and published jointly with the International Union of Crystallography. The first three volumes covered the years 1935-1971. The present volume provides references principally to compounds whose struc tures were reported in the literature during 1971-1972. A few structures published prior to 1971 and omitted from the previous volumes are also inc1uded. The arrangement of entries in the 86 chemical c1asses is identical with the previous volumes and the reader is referred to the Introduction in Vol. 1 or Vol. 2 for a description of the practical use of the bibliography. There are three cumulative indexes in the present volume: formula, transition metal and author indexes. All three cover the period 1935- 1972 and give references to entries in Vols. 1-4. The bibliography and indexes were prepared, checked and printed by computer techniques described in the previous volumes. Magnetic tapes of the four volumes are available and anyone interested should contact the Centre for further details. In the present volume we have attempted to improve the cut-off date by special arrangement with the Centre National de la Recherche Scientifique, Paris, France. Und er this arrangement reprints ofpapers containing crystallographic data are now sent directly to the Crystal lographic Data Centre, Cambridge, at the same time as they are sent out to abstractors preparing material for the Bulletin Signaletique.




Structure and Bonding in Crystalline Materials


Book Description

One of the motivating questions in materials research today is, how can elements be combined to produce a solid with specified properties? This book is intended to acquaint the reader with established principles of crystallography and cohesive forces that are needed to address the fundamental relationship between the composition, structure and bonding. Starting with an introduction to periodic trends, the book discusses crystal structures and the various primary and secondary bonding types, and finishes by describing a number of models for predicting phase stability and structure. Containing a large number of worked examples, exercises, and detailed descriptions of numerous crystal structures, this book is primarily intended as an advanced undergraduate or graduate level textbook for students of materials science. It will also be useful to scientists and engineers who work with solid materials.




Elements of Structures and Defects of Crystalline Materials


Book Description

Elements of Structures and Defects of Crystalline Materials has been written to cover not only the fundamental principles behind structures and defects, but also to provide deep insights into understanding the relationships of properties, defect chemistry and processing of the concerned materials. Part One deals with structures, while Part Two covers defects. Since the knowledge of the electron configuration of elements is necessary for understanding the nature of chemical bonding, it is discussed in the opening chapter. Chapter Two then describes the bonding formation within the crystal structures of varied materials, with Chapter Three delving into how a material's structure is formed. In view of the importance of the effects of the structure distortion on the material properties due to the fields, the related topics have been included in section 3.4. Moreover, several materials still under intensive investigation have been illustrated to provide deep insights into understanding the effects of the relationships of processing, structures and defects on the material properties. The defects of materials are explored in Part II. Chapter 4 deals with the point defects of metal and ceramics. Chapter 5 covers the fundamentals of the characteristics of dislocations, wherein physics and the atomic mechanics of several issues have been described in detail. In view of the significant influence of the morphologies including size, shape and distribution of grains, phases on the microstructure evolution, and, in turn, the properties of materials, the final chapter focuses on the fundamentals of interface energies, including single phase (grain) boundary and interphase boundary. - Discusses the relationship between properties, defect chemistry and the processing of materials - Presents coverage of the fundamental principles behind structures and defects - Includes information on two-dimensional and three-dimensional imperfections in solids
