Crystallography Made Crystal Clear makes crystallography accessible to readers who have no prior knowledge of the field or its mathematical basis. This is the most comprehensive and concise reference for beginning Macromolecular crystallographers, written by a leading expert in the field. Rhodes' uses visual and geometric models to help readers understand the mathematics that form the basis of x-ray crystallography. He has invested a great deal of time and effort on World Wide Web tools for users of models, including beginning-level tutorials in molecular modeling on personal computers. Rhodes' personal CMCC Home Page also provides access to tools and links to resources discussed in the text. Most significantly, the final chapter introduces the reader to macromolecular modeling on personal computers-featuring SwissPdbViewer, a free, powerful modeling program now available for PC, Power Macintosh, and Unix computers. This updated and expanded new edition uses attractive four-color art, web tool access for further study, and concise language to explain the basis of X-ray crystallography, increasingly vital in today's research labs.
* Helps readers to understand where models come from, so they don't use them blindly and
inappropriately
* Provides many visual and geometric models for understanding a largely mathematical method
* Allows readers to judge whether recently published models are of sufficiently high quality and detail to be useful in their own work
* Allows readers to study macromolecular structure independently and in an open-ended fashion on their own computers, without being limited to textbook or journals illustrations
* Provides access to web tools in a format that will not go out of date. Links will be updated and added as existing resources change location or are added

There is no question that the field of solid state electronics, which essentially began with work at Bell laboratories just after World War II, has had a profound impact on today's Society. What is not nearly so widely known is that advances in the art and science of crystal growth underpin this technology. Single crystals, once valued only for their beauty, are now found, in one form or another in most electronic, optoelectronic and numerous optical devices. These devices, in turn, have permeated almost every home and village throughout the world. In fact it is hard to imagine what our electronics industry, much less our entire civilization, would have been like if crystal growth scientists and engineers were unable to produce the large, defect free crystals required by device designers.
This book brings together two sets of related articles describing advances made in crystal growth science and technology since World War II. One set is from the proceedings of a Symposium held in August 2002 to celebrate 50 years of progress in the field of crystal growth. The second contains articles previously published in the newsletter of the American Association for Crystal Growth in a series called "Milestones in Crystal Growth."
The first section of this book contains several articles which describe some of the early history of crystal growth prior to the electronics revolution, and upon which modern crystal growth science and technology is based. This is followed by a special article by Prof. Sunagawa which provides some insight into how the successful Japanese crystal growth industry developed. The next section deals with crystal growth fundamentals including concepts of solute distribution, interface kinetics, constitutional supercooling, morphological stability and the growth of dendrites. The following section describes the growth of crystals from melts and solutions, while the final part involves thin film growth by MBE and OMVPE.
These articles were written by some of the most famous theorists and crystal growers working in the field. They will provide future research workers with valuable insight into how these pioneering discoveries were made, and show how their own research and future devices will be based upon these developments.

Crystals are the unacknowledged pillars of modern technology. The modern technological developments depend greatly on the availability of suitable single crystals, whether it is for lasers, semiconductors, magnetic devices, optical devices, superconductors, telecommunication, etc. In spite of great technological advancements in the recent years, we are still in the early stage with respect to the growth of several important crystals such as diamond, silicon carbide, PZT, gallium nitride, and so on. Unless the science of growing these crystals is understood precisely, it is impossible to grow them as large single crystals to be applied in modern industry.
This book deals with almost all the modern crystal growth techniques that have been adopted, including appropriate case studies. Since there has been no other book published to cover the subject after the Handbook of Crystal Growth, Eds. DTJ Hurle, published during 1993-1995, this book will fill the existing gap for its readers.
The book begins with ""Growth Histories of Mineral Crystals"" by the most senior expert in this field, Professor Ichiro Sunagawa. The next chapter reviews recent developments in the theory of crystal growth, which is equally important before moving on to actual techniques. After the first two fundamental chapters, the book covers other topics like the recent progress in quartz growth, diamond growth, silicon carbide single crystals, PZT crystals, nonlinear optical crystals, solid state laser crystals, gemstones, high melting oxides like lithium niobates, hydroxyapatite, GaAs by molecular beam epitaxy, superconducting crystals, morphology control, and more. For the first time, the crystal growth modeling has been discussed in detail with reference to PZT and SiC crystals.

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.

There have been several recent breakthroughs in the supramolecular domain: larger molecular components are being synthesized; 2D layers involving multiple recognition sites; crystals with intricate building blocks are being designed; more components are being used in assembly and self-assembly "algorithms" (some having molecular weights as high as 15,000); and there is an increasing versatility in applications. The difficulty in characterizing and obtaining structural information on such large assemblies has increased to such a level that no single technique is now adequate. Various methods have now been upgraded and are being combined: X-ray diffraction (structures with hundreds of independent atoms), NMR, AFM/STM (manipulation of a single molecule), FAB/MS, time-resolved techniques up to the picosecond range, new computational approaches, and others. The present book aims to shed light on the most recent developments in both the synthesis of novel assemblies and on current methods for their characterization.

This book is by far the most comprehensive treatment of point and space groups, and their meaning and applications. Its completeness makes it especially useful as a text, since it gives the instructor the flexibility to best fit the class and goals. The instructor, not the author, decides what is in the course. And it is the prime book for reference, as material is much more likely to be found in it than in any other book; it also provides detailed guides to other sources.Much of what is taught is folklore, things everyone knows are true, but (almost?) no one knows why, or has seen proofs, justifications, rationales or explanations. (Why are there 14 Bravais lattices, and why these? Are the reasons geometrical, conventional or both? What determines the Wigner-Seitz cells? How do they affect the number of Bravais lattices? Why are symmetry groups relevant to molecules whose vibrations make them unsymmetrical? And so on). Here these analyses are given, interrelated, and in-depth. The understanding so obtained gives a strong foundation for application and extension. Assumptions and restrictions are not merely made explicit, but also emphasized.In order to provide so much information, details and examples, and ways of helping readers learn and understand, the book contains many topics found nowhere else, or only in obscure articles from the distant past. The treatment is (often completely) different from those elsewhere. At least in the explanations, and usually in many other ways, the book is completely new and fresh. It is designed to inform, educate and make the reader think. It strongly emphasizes understanding.The book can be used at many levels, by many different classes of readers - from those who merely want brief explanations (perhaps just of terminology), who just want to skim, to those who wish the most thorough understanding. remove remove

Hardbound. The apatites and related calcium phosphates have been of considerable interest to biologists, mineralogists, and inorganic and industrial chemists for many years. This book contains a detailed description of the structures and structural interrelationships of the calcium orthophosphates, including the apatites. Their preparation, crystal growth and dissolution, chemical reactions including thermal decomposition, IR, Raman and NMR spectra and various physical properties are discussed. Apatites other than those containing calcium and phosphorus are included. Synthetic, mineral and biological carbonate apatites are also considered. A wide, but critical coverage of the literature is given, which includes a substantial amount not written in English. Research from many disciplines is included which results in a comprehensive compilation of recent work.

This book contains the contributions of 13 well known specialists in the field of solid state chemistry who had been invited as lecturers at a 1992 NATO Advanced Study Institute in Erice, Sicily. The chapters of a more general character concern the use of the space group - subgroup relationships for the recognition of structure families, the crystal chemical formulae (which is a way of denoting simple crystal chemical information in a condensed form), the concepts of atom co-ordination, atom volume and charge transfer and the physicist's view of the bond strength in the solid which is measured by the crystal orbital overlap population. It is demonstrated for the case of ionic compounds that the bond valence method is superior to the old sum-of-radii method for the prediction of interatomic distances. Simple valence electron rules can be applied fto compounds with tetrahedral anion complexes. These rules allow one not only to make predictions on expected structural features of unknown compounds, but also to point out inconsistencies between the reported structure and composition of known compounds. Detailed accounts are presented on the crystal chemistry of the superconducting copper oxides, the sulfosalts, the metal cluster compounds, the silicates and the transition metal borides and related compounds. In the case of intermetalic compounds the intergrowth concept is found to be very useful for an "understanding" of complicated atom arrangements. At the end of each chapter there can be found problems and their solutions. This makes it possible for (advanced) undergraduates in chemistry, physics, metallurgy, materials science and mineralogy to be able to profit from a study of this book.

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.

Small-angle scattering of X-rays (SAXS) and neutrons (SANS) is an established method for the structural characterization of biological objects in a broad size range from individual macromolecules (proteins, nucleic acids, lipids) to large macromolecular complexes. SAXS/SANS is complementary to the high resolution methods of X-ray crystallography and nuclear magnetic resonance, allowing for hybrid modeling and also accounting for available biophysical and biochemical data. Quantitative characterization of flexible macromolecular systems and mixtures has recently become possible. SAXS/SANS measurements can be easily performed in different conditions by adding ligands or binding partners, and by changing physical and/or chemical characteristics of the solvent to provide information on the structural responses. The technique provides kinetic information about processes like folding and assembly and also allows one to analyze macromolecular interactions. The major factors promoting the increasingly active use of SAXS/SANS are modern high brilliance X-ray and neutron sources, novel data analysis methods, and automation of the experiment, data processing and interpretation. In this book, following the presentation of the basics of scattering from isotropic macromolecular solutions, modern instrumentation, experimental practice and advanced analysis techniques are explained. Advantages of X-rays (rapid data collection, small sample volumes) and of neutrons (contrast variation by hydrogen/deuterium exchange) are specifically highlighted. Examples of applications of the technique to different macromolecular systems are considered with specific emphasis on the synergistic use of SAXS/SANS with other structural, biophysical and computational techniques.

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.

Self-sufficient and user-friendly, this book provides a complete introduction to the anisotropic elasticity theory necessary to model a wide range of crystal defects. Assuming little prior knowledge of the subject, the reader is first walked through the required basic mathematical techniques and methods. This is followed by treatments of point, line, planar and volume type defects such as vacancies, dislocations, grain boundaries, inhomogeneities and inclusions. Included are analyses of their elastic fields, interactions with imposed stresses and image stresses, and interactions with other defects, all employing the basic methods introduced earlier. This step by step approach, aided by numerous exercises with solutions provided, strengthens the reader's understanding of the principles involved, extending it well beyond the immediate scope of the book. As the first comprehensive review of anisotropic elasticity theory for crystal defects, this text is ideal for both graduate students and professional researchers.

Crystal structures and their associated electronic features play an enormous role in chemistry, constituting the most fundamental basis for analyzing and predicting properties of solid-state materials. In Crystal Structure: Properties, Characterization and Determination, the authors begin by discussing some of the refining models and X-ray data treatments for single-crystals containing heavy atoms, such as transition metals or lanthanides.Valuable information on crystal structures and microstructures may be obtained from the observation of high-resolution images if conditions associated iwth crystal thickness and defocus values are satisfied. These images include information not only on accurate atomic coordinates of cations but also on the ordered arrangements of oxygen atoms and oxygen vacancies.In the concluding study, measurements of the heat capacity of Y3-xErxAl5O12 (x=0,0.6,1.1,3), and mixed Er3-xTmx Al5O12, (x=0,1,2,3) and Er2HoAl5O12 solid solutions were carried out in the temperature range of 1.9 to 220 K in magnetic fields up to 9T. The findings suggest that heat capacity variations at low temperatures were impacted by Schottky anomalies.

Die modernen Konzepte der physikalischen Metallkunde sind gleichermassen grundlegend fur das Verstandnis auch aller nichtmetallischen Werkstoffe. Deswegen liegt es nahe, die klassisch nach den Werkstoffen Metall, Keramik, Glas und Kunststoff differenzierten Wissensgebiete unter der verbindenden Bezeichnung Materialwissenschaft und Werkstofftechnik gemeinsam abzuhandeln. Von dieser Feststellung ausgehend fuhrt dieses Lehrbuch zwar zunachst in die Allgemeine Metallkunde ein, daruber hinaus legt es aber auch die Grundlagen fur die gesamte Materialwissenschaft und Werkstofftechnik. Im Mittelpunkt steht dabei der naturwissenschaftliche Aspekt der Materialkunde, ohne dass ihr ingenieurwissenschaftlicher Anteil vernachlassigt wurde.

Dieses Konzept wird auch in der aktuellen4. Auflage erfolgreich umgesetzt. Modernen Entwicklungen wurde vor allem durch Erweiterungen uber neue Werkstoffe, wie z.B. dunne Filme, metallische Glaser oder Nanorohrchen Rechnung getragen. Ausserdem wurde jedes Kapitel durch Ubungsaufgaben mit Losungen erweitert."

The pharmaceutical industry has become acutely aware of the importance of the solid state, but pharmaceutical scientists often lack specific training in topics related to solid-state structure and crystallography. This book provides needed support in this topical area. Taking an intuitive and informal approach to solid-state structure and crystallographic concepts, this book is written for anyone who needs a clear understanding of modern crystallography, with specific reference to small-molecule pharmaceutical solids. The author describes molecular crystals and crystal structures, symmetry, space groups, single-crystal and powder X-ray diffraction techniques and the analysis and interpretation of crystallographic data. Useful technical details are presented where necessary and case studies from the pharmaceutical literature put theory into a practical context. Written by an internationally leading figure and with its focus on molecular crystals, this book is equally applicable to chemists with a need to understand and apply X-ray crystal-structure determination.

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.
