Coverage For some time, we have contemplated a comprehensive review of the structures and force fields of the binary fluorides. This bibliography of 1498 references marks the first step of that effort. We are pub lishing this material now rather than waiting until the review is complete some two years hence because we believe that the information already accumulated will be of immediate use to a broad spectrum of researchers. Anyone ambitious enough to read through all the articles on binary fluorides will find that the struc tures and force fields of many of these molecules are at present unknown. For example, it has not been clearly established to which point group(s) the lanthanide trifluorides should be assigned. There remain interesting problems relating to the role of Jahn-Teller and pseudo-Jahn-Teller distortions in some of the transition metal fluorides such as VF , MoF , ReF , and ReF , to name only a few. One s s 6 7 also finds fascinating examples of large-amplitude motions, or pseudorotations, as they are often called, in such molecules as XeF 6, I F 7, and PF 5' For those binary fluorides whose equilibrium geometries are precisely known, there still exists the problem of accurately determining the harmonic force field. In a few cases, most notably the Group VA trifluorides, there has been some attempt made at extracting the cubic and quartic contributions to the force field.
Progress in the Science and Technology of the Rare Earths, Volume 2 is a collection of papers that details the advancement in various areas of rare earth technology. The coverage of the text includes the practical applications and methods of preparation of rare earth materials. The selection also covers topics about the various properties of rare earths, such as the molecular field model of exchange coupling in rare earth materials; thermodynamic and magnetic properties of the rare earth chalcogenides and pnictides; and structural and solid state chemistry of pure rare earth oxides. The book will be of great use to individuals involved in the research and development of technologies that utilize rare earth materials.
This book summarizes recent progresses in inorganic fluorine chemistry. Highlights include new aspects of inorganic fluorine chemistry, such as new synthetic methods, structures of new fluorides and oxide fluorides, their physical and chemical properties, fluoride catalysts, surface modifications of inorganic materials by fluorination process, new energy conversion materials and industrial applications. Fluorine has quite unique properties (highest electronegativity; very small polarizability). In fact, fluorine is so reactive that it forms fluorides with all elements except with the lightest noble gases helium, neon and argon. Originally, due to its high reactivity, fluoride chemistry faced many technical difficulties and remained undeveloped for many years. Now, however, a large number of fluorine-containing materials are currently produced for practical uses on an industrial scale and their applications are rapidly extending to many fields. Syntheses and structure analyses of thermodynamically unstable high-oxidation-state fluorides have greatly contributed to inorganic chemistry in this decade. Fluoride catalysts and surface modifications using fluorine are developing a new field of fluorine chemistry and will enable new syntheses of various compounds. The research on inorganic fluorides is now contributing to many chemical energy conversion processes such as lithium batteries. Furthermore, new theoretical approaches to determining the electronic structures of fluorine compounds are also progressing. On the industrial front, the use of inorganic fluorine compounds is constantly increasing, for example, in semi-conductor industry. "Advanced Inorganic Fluorides: Synthesis, Characterization and Applications" focuses on these new features in inorganic fluorine chemistry and its industrial applications. The authors are outstanding experts in their fields, and the contents of the book should prove to be of valuable assistance to all chemists, graduates, students and researchers in the field of fluorine chemistry.
The 21st conference proceedings continue the tradition of the ICPS series. The proceedings cover all aspects of semiconductor physics, including those related to materials, processing and devices. Plenary and invited speakers address areas of major interest.
Fluorine Chemistry, Volume V focuses on the compositions, reactions, properties, and functions of fluorine compounds. The book first discusses the general chemistry of fluorine compounds and the physical chemistry of fluorocarbons. Vapor pressures; details of interaction of polyatomic molecules; coefficients and equations of state for gases; liquid compressibility; and compressibilities of liquid mixtures are discussed. The text looks at the radiochemistry and radiation chemistry of fluorine. Isotopes of fluorine; useful methods for producing F18 and F20; radiochemical properties and counting of F20; fluorine activities in nuclear reactors; and analytical determinations are described. The selection also provides numerical analysis and tabulated representations. The book also focuses on the industrial and utilitarian features of fluorine chemistry. Historical and economic factors; properties of fluorocarbons; refrigerants and propellants; gaseous dielectrics; fire extinguishing agents; and fluorocarbon surfactants are discussed. The text is a vital source of data for readers wanting to study fluorine compounds.
Photonic and Electronic Properties of Fluoride Materials: Progress in Fluorine Science, the first volume in this new Elsevier series, provides an overview of the important optical, magnetic, and non-linear properties of fluoride materials. Beginning with a brief review of relevant synthesis methods from single crystals to nanopowders, this volume offers valuable insight for inorganic chemistry and materials science researchers. Edited and written by leaders in the field, this book explores the practical aspects of working with these materials, presenting a large number of examples from inorganic fluorides in which the type of bonding occurring between fluorine and transition metals (either d- or 4f-series) give rise to peculiar properties in many fundamental and applicative domains. This one-of-a-kind resource also includes several chapters covering functional organic fluorides used in nano-electronics, in particular in liquid crystal devices, in organic light-emitting diodes, or in organic dyes for sensitized solar cells. The book describes major advances and breakthroughs achieved by the use of fluoride materials in important domains such as superconductivity, luminescence, laser properties, multiferroism, transport properties, and more recently, in fluoro-perovskite for dye-sensitized solar cells and inorganic fluoride materials for NLO, and supports future development in these varied and key areas. The book is edited by Alain Tressaud, past chair and founder of the CNRS French Fluorine Network. Each book in the collection includes the work of highly-respected volume editors and contributors from both academia and industry to bring valuable and varied content to this active field.
