Book Description
The material in this book is based on invited and contributed pa pers presented at the NATO Advanced Research Workshop on INon-stoichio l metric Compounds held in Ringberg Castle, Rottach-Egern (Bavarian Alps), Germany, July 3-9, 1988. The workshop followed previous meetings held in Mogilany, Poland (1980), Alenya, France (1982), Penn State, USA (1984) and Keele University, UK (1986). The aim of these workshops is to present and discuss up-to-date knowledge in the study of non-stoichiometry and its effect on materials properties as well as to indicate the most urgent research pathways required in this field. Since the subject of non-stoichiometry is interdisciplinary, the workshops bring together solid state physicists and chemists, surface scientists, materials scientists, ceramists and metallurgists. The present workshop, which gathered 42 scientists of an inter national reputation, mainly considered the effect of surfaces, grain boundaries and structural defects on materials properties. From discus sions during this meeting it emerged that correct understanding of properties of ceramic materials requires urgent studies on the defect structure of the interface region. Progress in this direction requires the development of the interface defect chemistry. This is the task for materials scientists in the near future. The present proceedings includes both theoretical and experimen tal work on general aspects of non-stoichiometry, defect structure and diffusion in relation to the bulk and to the interface region of such materials as high tech ceramics, solid electrolytes, electronic cera mics, nuclear materials and high Tc oxide superconductors.

Book Description
Nonstoichiometric Oxides discusses the thermodynamic and structural studies of nonstoichiometric oxides. This eight-chapter text also covers the defect-defect interactions in these compounds. The introductory chapters describe the thermodynamic properties of nonstoichiometric oxides in terms of defect complexes using the classical thermodynamic principles and from a statistical thermodynamics point of view. These chapters also include statistical thermodynamic models that indicate the ordered nonstoichiometric phase range in these oxides. The subsequent chapters examine the transport properties, such as diffusion and electrical conductivity. Diffusion theories and experimental diffusion coefficients for several systems, as well as the electrical properties of the highly defective ionic and mixed oxide conductor, are specifically tackled in these chapters. The concluding chapters present the pertinent results obtained in nonstoichiometric oxide structural studies using high-resolution electron microscopy and X-ray and neutron diffraction. Inorganic chemists and inorganic chemistry teachers and students will greatly appreciate this book.

Book Description
Non-Stoichiometric Compounds: Tungsten Bronzes, Vanadium Bronzes and Related Compounds deals with the chemistry of non-stoichiometric compounds such as tungsten bronzes and vanadium bronzes. Topics covered include the thermodynamic basis for lattice defects and non-stoichiometry; thermodynamics of binary crystals; non-stoichiometry in ionic crystals; and interaction of defects. A structural view of non-stoichiometric compounds is also presented. Comprised of two parts, this volume begins with a historical account of developments in non-stoichiometry, focusing on the thermodynamic treatments and structural descriptions of non-stoichiometric compounds. The discussion then turns to the thermodynamic basis for lattice defects and non-stoichiometry, along with the thermodynamics of binary crystals and electronic defects in ionic crystals. Classical defect models are also described, and defect interactions in non-stoichiometric compounds are considered, together with the thermodynamics and crystallography in such compounds. The last section is devoted to tungsten bronzes, vanadium bronzes, and related compounds including bronzes of molybdenum, rhenium, niobium, tantalum, titanium, manganese, platinum, and palladium. This book is intended for inorganic chemists.

Book Description
This book is written for scientists who require information on organobismuth chemistry, either by specific topic or by compound. "Organobismuth Chemistry" covers, through early 1999, stoichiometric compounds that contain the Bi-C bond; not included, with the exception of a few examples, are inorganic compounds, minerals, metal alloys, and non-stoichiometric materials.Organobismuth chemistry is covered in a comprehensive, self-contained manner. The book focuses on the academic aspects of the field; therefore, references to patents are made only when pertinent. Chapter 1 serves as an introduction to bismuth as the element. In chapters 2 to 4, organobismuth compounds are classified according to the types of compounds and dealt in detail. Chapter 5 is devoted to the use of bismuth and derivatives in organic transformations. In the first four chapters, brief to moderate descriptions for selected experimental procedures are included; they are intended to inform the readers of relevant protocols and should serve in preparative studies which are based on analogies. In the final chapter the X-ray data of fundamental and/or structurally interesting organobismuth (III) and (V) compounds are collected. At the beginning of each chapter, the text is preceded by detailed table of contents of the subject dealt in it. By inspection of the table, it should be possible to locate quickly information on a specific organobismuth compound.Definite efforts have been made to include all factual data pertinent to an understanding of each class of organobismuth compounds. The main attention is paid to the methods of synthesis, molecular structure, and chemical behaviours of organobismuth compounds, although some knowledge of spectroscopy and other physical properties are also included. The format for presenting information has both descriptive information and numerical data. Numerical data are mostly presented in tabular form. Tables of known compounds in each chapter are organized so as to enable the readers to make easy access to the most relevant data source of a compound. The nomenclature does not follow strictly the recommendations of IUPAC, but usage is mostly consistent with common practice in the current literature. In order to help the readers to save time in looking for appropriate spectral data, an effort has also been made to provide the IR, MS, NMR and UV spectral data sources in tabular form. All references for chapters are collected together in a list at the end of the book. In the list, references are given chronologically both in code and in full form, with authors names.This book will appeal to academic and industrial researchers alike, and will be particularly useful to chemists engaged in bench work. In addition it is hoped that this book will provide a stimulus as the basis for further development of organobismuth chemistry.

Book Description
Problem solving is central to the teaching and learning of chemistry at secondary, tertiary and post-tertiary levels of education, opening to students and professional chemists alike a whole new world for analysing data, looking for patterns and making deductions. As an important higher-order thinking skill, problem solving also constitutes a major research field in science education. Relevant education research is an ongoing process, with recent developments occurring not only in the area of quantitative/computational problems, but also in qualitative problem solving. The following situations are considered, some general, others with a focus on specific areas of chemistry: quantitative problems, qualitative reasoning, metacognition and resource activation, deconstructing the problem-solving process, an overview of the working memory hypothesis, reasoning with the electron-pushing formalism, scaffolding organic synthesis skills, spectroscopy for structural characterization in organic chemistry, enzyme kinetics, problem solving in the academic chemistry laboratory, chemistry problem-solving in context, team-based/active learning, technology for molecular representations, IR spectra simulation, and computational quantum chemistry tools. The book concludes with methodological and epistemological issues in problem solving research and other perspectives in problem solving in chemistry. With a foreword by George Bodner.
