DOWNLOAD EBOOKA concise introduction to modern crystal structure determination, emphasizing both the crystallographic background and the successive practical steps. In the theoretical sections, more importance is attached to a good understanding, than to a rigorous mathematical treatment. The most important measuring techniques, including the use of modern area detectors, and the methods of data reduction, structure solution and refinement are discussed from a practical point of view. Special emphasis is put on the ability to recognize and avoid possible errors and traps, and to judge the quality of results.

DOWNLOAD EBOOKThis volume is devoted to the electron and phonon energy states of inorganic layered crystals. The distinctive feature of these low-dimensional materials is their easy mechanical cleavage along planes parallel to the layers. This feature implies that the chemical binding within each layer is much stronger than the binding between layers and that some, but not necessarily all, physical properties of layered crystals have two-dimensional character. In Wyckoff's Crystal Structures, SiC and related com pounds are regarded as layered structures, because their atomic layers are alternately stacked according to the requirements of cubic and hexagonal close-packing. How ever, the uniform (tetrahedral) coordination of the atoms in these compounds excludes the kind of structural anisotropy that is fundamental to the materials dis cussed in this volume. An individual layer of a layered crystal may be composed of either a single sheet of atoms, as in graphite, or a set of up to five atomic sheets, as in Bi2 Te3' A layer may also have more complicated arrangements of the atoms, as we find for example in Sb S . But the unique feature common to all these materials is 2 3 the structural anisotropy, which directly affects their electronic and vibrational properties. The nature of the weak interlayer coupling is not very well understood, despite the frequent attribution of the coupling in the literature to van der Waals forces. Two main facts, however, have emerged from all studies.

DOWNLOAD EBOOKFor many years, evidence suggested that all solid materials either possessed a periodic crystal structure as proposed by the Braggs or they were amorphous glasses with no long-range order. In the 1970s, Roger Penrose hypothesized structures (Penrose tilings) with long-range order which were not periodic. The existence of a solid phase, known as a quasicrystal, that possessed the structure of a three dimensional Penrose tiling, was demonstrated experimentally in 1984 by Dan Shechtman and colleagues. Shechtman received the 2011 Nobel Prize in Chemistry for his discovery. The discovery and description of quasicrystalline materials provided the first concrete evidence that traditional crystals could be viewed as a subset of a more general category of ordered materials. This book introduces the diversity of structures that are now known to exist in solids through a consideration of quasicrystals (Part I) and the various structures of elemental carbon (Part II) and through an analysis of their relationship to conventional crystal structures. Both quasicrystals and the various allotropes of carbon are excellent examples of how our understanding of the microstructure of solids has progressed over the years beyond the concepts of traditional crystallography.

DOWNLOAD EBOOKThe progress of civilization can be, in part, attributed to their ability to employ metallurgy. This book is an introduction to multiple facets of physical metallurgy, materials science, and engineering. As all metals are crystalline in structure, it focuses attention on these structures and how the formation of these crystals are responsible for certain aspects of the material's chemical and physical behaviour. Concepts in Physical Metallurgy also discusses the mechanical properties of metals, the theory of alloys, and physical metallurgy of ferrous and non-ferrous alloys.

DOWNLOAD EBOOKThis survey of the important types of inorganic and organic crystal structures treats its subject thoroughly and in sufficient depth for undergraduate modules in chemistry courses. Features of this book are the instructions for 3D stereoviewing which is central to a full appreciation of the presentation. Clear directions for making your own stereo have been provided in the book, which enables readers to examine the plentiful stereo of lattices and crystal structures which are illustrated. The introductory chapter explains point-group and space-group symmetry insofar as required to understand lattices and crystal structures. Crystal structures are sub-divided according to the atomic force mainly responsible for cohesion in the solid state, The descriptions of the structures are gi in crystallographic terms, including data on the space group, molecular symmetry and molecular geometry. Discussions of bonding theory for each sub-division of the structures enhance and strengthen the author’s presentation. The book stems from the author’s successful lecture courses, tested and refined in class teaching. It draws as necessary on equilibrium thermodynamics and other chemical topics, with avoidance of advanced mathematics, A level being the prerequisite. Examines the important types of inorganic and organic crystal structures Includes instructions for making simple stereoviewers and computer programs Draws, as necessary, on equilibrium thermodynamics and other chemical topics, with avoidance of advanced mathematics

DOWNLOAD EBOOKThis concise text describes the basic principles of crystal structure determination by X-ray diffraction and the application of these principles in practice. The technique is presented step-by-step and illustrated with a wide range of case studies, including the use of the most up-to-date equipment. Crystal Structure Determination explains how X-ray crystallography fits in with modern chemistry, why it is important, and what it can do, with the aim of enabling the reader to understand and assess structural results in books and research journals. There is additional coverage of related topics such as neutron diffraction and the application of computer databases. Mathematical treatment is kept at a relatively low level and is complemented by extensive illustrations and worked examples. This clear introduction to the topic will be an essential text for chemistry undergraduates. Other related science undergraduates (biochemists, environmental scientists, etc.) and postgraduate chemists will also find this book useful.
