The bond valence model, a description of acid-base bonding, is
widely used for analysing and modelling the structures and
properties of solids and liquids. Unlike other models of inorganic
chemical bonding, the bond valence model is simple, intuitive, and
predictive, and is accessible to anyone with a pocket calculator
and a secondary school command of chemistry and physics. This new
edition of 'The Chemical Bond in Inorganic Chemistry: The Bond
Valence Model' shows how chemical properties arise naturally from
the conflict between the constraints of chemistry and those of
three-dimensional space. The book derives the rules of the bond
valence model, as well as those of the traditional covalent, ionic
and popular VSEPR models, by identifying the chemical bond with the
electrostatic flux linking the bonded atoms. Most of the new
edition is devoted to showing how to apply these ideas to real
materials including crystals, liquids, glasses and surfaces. The
work includes detailed examples of applications, and the final
chapter explores the relationship between the flux and quantum
theories of the bond.
Crystallography is an interdisciplinary science covering a wide
area, from biology to earth sciences, mathematics and materials
science. Its role is growing, owing to the contribution
crystallography can offer to the understanding of such diverse
fields as biological structures, high-temperature superconductors,
mineral properties, and phase transitions. The book describes both
the theoretical bases and applications of different areas
interacting with crystallography. As with the first and second
editions, it is organized as a collection of chapters written by
recognized specialists, with all contributions being harmonized
into a unified whole. The main text is devoted to the presentation
of basics; the appendices deal with specialist aspects. In this
third edition topics have been updated so as to document the
present state of the art: emphasis is placed upon areas of current
research.
To facilitate learning and make teaching more effective, new
illustrations have been introduced. As with the second edition, a
software package is included via the book's OUP web site: modern
graphics will help users to better understand the basics of this
science via three-dimensional images, simulation of experiments,
and exercises.
In recent years, it has become apparent that knowing the average
atomic structure of materials is insufficient to understand their
properties. Diffuse scattering in addition to the Bragg scattering
holds the key to learning about defects in materials, the topic of
many recent books. What has been missing is a detailed step-by-step
guide on how to simulate disordered materials. The DISCUS cook book
fills this need covering simple topics such as building a computer
crystal to complex topics such as domain structures, stacking
faults or using advanced refinement techniques to adjust parameters
on a disordered model. The book contains a CD-ROM with all files
needed to recreate every example given using the program DISCUS.
The reader is free to follow the principles behind simulating
disordered materials or to get down into the details and run or
modify the given examples.
Handbook on the Physics and Chemistry of Rare Earths: Including
Actinides, Volume 61 presents the latest release in this continuous
series that covers all aspects of rare earth science, including
chemistry, life sciences, materials science and physics.
This book provides a comprehensive study of the symmetry and
geometry of crystals and molecules, starting from first principles.
The pre-knowledge assumed is mathematics and physical science to
about A-level; additional mathematical topics are discussed in
appendices. It is copiously illustrated, including many
stereoviews, with instructions both for stereoviewing and for
constructing a stereoviewer. Problems for each chapter are
provided, with fully worked tutorial solutions. A suite of
associated computer programs has been devised and placed on-line,
for assisting both the study of the text and the solutions of the
problems. The programs are easily executed, and instructions are
provided in the text and on the monitor screen. The applicability
of symmetry in everyday life as well as in science is stressed.
Point groups and space groups are first discussed and derived in a
semi-analytical manner, and later by use of group theory. The basic
principles of group theory are discussed, together with
applications to symmetry, chemical bonding and aspects of
vibrations of molecules and crystals. The book is addressed to
those studying the physical sciences and meeting the subject for
the first time, and it brings the reader to a level of appreciation
for the definitive works produced by the International Union of
Crystallography, such as the International Tables for X-ray
Crystallography, Vol 1 (1965) and the International Tables for
Crystallography, Vol A (2006).
Written by an experienced university teacher, this textbook is
based on the author's lectures, and is designed to answer students'
questions rather than delving into obscure details. The
well-balanced approach gives precedence to a visual, intuitive
understanding, with only as much math as is necessary. The author
covers the topic of symmetry in crystals from basic elements to
physical properties, backed by numerous clear-cut illustrations and
easy-to-read crystallographic tables.
The result is a compact and self-contained treatment suitable for
crystallography courses in physics, chemistry, materials science
and biology - irrespective of the academic background.
For many years it was believed that translational symmetry would be
the fundamental property of crystal structures of natural and
synthetic compounds. It is now recognised that many compounds
crystallise without translational symmetry of their atomic
structures. "Incommensurate Crystallography" gives a comprehensive
account of the superspace theory for the description of crystal
structures and symmetries of these incommensurately modulated
crystals and incommensurate composite crystals. It thus provides
the necessary background for quantitative analysis of
incommensurate crystals by methods in Solid State Chemistry and
Solid State Physics. The second half of "Incommensurate
Crystallography" is devoted to crystallographic methods of
structural analysis of incommensurate compounds. Thorough accounts
are given of the diffraction by incommensurate crystals, the choice
of parameters in structure refinements, and the use of superspace
in analysing crystal structures. The presentation of methods of
structure determination includes modern methods like the Maximum
Entropy Method and Charge Flipping.
"This book presents the reader with a fresh and unconventional
approach to teaching crystallographic symmetry. Whereas traditional
crystallography textbooks make a heavy use of algebra and rapidly
become very technical, this book adopts in the first few chapters a
'pictorial' approach based on the symmetry diagrams of the
International Tables for Crystallography. Readers are led
step-by-step through simple 'frieze' and 'wallpaper' patterns, with
many examples from the visual arts. At the end of chapter 3 they
should be able to identify and analyse all these simple symmetries
and apply to them the nomenclature and symbols of the International
Tables. Mathematical formalism is introduced later on in the book,
and by that time the reader will have gained a solid intuitive
grasp of the subject matter. This book will provide graduate
students, advanced undergraduate students and practitioners in
physics, chemistry, earth sciences and structural biology with a
solid foundation to master the International Tables of
Crystallography, and to understand the relevant literature"--
This book shows how the fundamentals of electron paramagnetic
resonance (EPR) spectroscopy are practically implemented and
illustrates the diversity of current applications. The technique is
used at various levels, and applications are presented in order of
increasing difficulty, with reference to theoretically obtained
results. This book features a diverse array of application
examples, from fields such as ionizing radiation dosimetry,
neurodegenerative diseases, structural transitions in proteins, and
the origins of terrestrial life. The final chapter of this book
highlights the principles and applications of the technique of
ferromagnetic resonance spectroscopy, followed by a brief
introduction to advanced EPR techniques such as electron spin echo
envelope modulation (ESEEM), hyperfine sub-level correlation
(HYSCORE), pulsed electron-electron double resonance (PELDOR), and
continuous wave electron nuclear double resonance (ENDOR)
experiments.
Understanding the mechanisms of crystallization processes on the
molecular level is an essential step in the control of the
formation of crystals. These crystals may be a desirable solid
product or an undesirable precipitate. Crystallization Processes
- covers the theory, research, applications and control of
crystallization processes from a homogeneous liquid to a solid
phase.
- considers the behaviour of ions and molecules in homogeneous
supersaturated solutions and also in liquid metals and ionic
melts.
- discusses recent work on ionic solvation desolvation phenomena,
association of ions and molecules in solution and precipitation and
dissolution of crystals.
- includes the mechanism of crystallization of calcium carbonate
and other simple inorganic electrolytes, amino acids, lipids and
proteins.
Crystallization Processes is a valuable source of information for
all who are interested in the behaviour of solutions especially the
theoretical and practical aspects of crystallization phenomena.
These include physical, inorganic and organic chemists, materials
scientists and chemical engineers who wish to optimize industrial
processes. The Wiley Series in Solution Chemistry fills the
increasing need to present authoritative, comprehensive and fully
up-to-date accounts of the many aspects of solution chemistry.
Internationally recognized experts from research or teaching
institutions in various countries are invited to contribute to the
series.
