Book Description
The history of the rare earths has entered its third century; trans uranium elements are now a half century old. Both the lanthanide and actinide ele­ ments, 30 elements altogether, are f elements, meaninj that their metallic 2 1 1 electronic configurations are typically 6s 5d 4f" and 7s 6d 5f" respectively. To an elementary approximation as summarized in the 'average inorganic chemistry textbook, these configurations cause their chemistry to be described by the trivalent state accompanied by less interesting effects such as the lanthanide contraction. However, the discovery of divalent and tetravalent lanthanides and di- to seven-valent actinides hinted at the existence of more interesting although still classic solid-state and coor­ dination chemistry. Metallic halides and chalcogenides and electron-poor cluster compounds have been the outgrowth of many synthetic efforts during the past 25 years or so. These days, one can say that the lan­ thanides and actinides are not at all boring; the fascination arises from every element being an individual, having its own chemistry.

Book Description
The fourth edition of "The Chemistry of the Actinide and Transactinide Elements" comprises all chapters in volumes 1 through 5 of the third edition (published in 2006) plus a new volume 6. To remain consistent with the plan of the first edition, “ ... to provide a comprehensive and uniform treatment of the chemistry of the actinide [and transactinide] elements for both the nuclear technologist and the inorganic and physical chemist,” and to be consistent with the maturity of the field, the fourth edition is organized in three parts. The first group of chapters follows the format of the first and second editions with chapters on individual elements or groups of elements that describe and interpret their chemical properties. A chapter on the chemical properties of the transactinide elements follows. The second group, chapters 15-26, summarizes and correlates physical and chemical properties that are in general unique to the actinide elements, because most of these elements contain partially-filled shells of 5f electrons whether present as isolated atoms or ions, as metals, as compounds, or as ions in solution. The third group, chapters 27-39, focuses on specialized topics that encompass contemporary fields related to actinides in the environment, in the human body, and in storage or wastes. Two appendices at the end of volume 5 tabulate important nuclear properties of all actinide and transactinide isotopes. Volume 6 (Chapters 32 through 39) consists of new chapters that focus on actinide species in the environment, actinide waste forms, nuclear fuels, analytical chemistry of plutonium, actinide chalcogenide and hydrothermal synthesis of actinide compounds. The subject and author indices and list of contributors encompass all six volumes.

Book Description
Solid state chemistry is a multidisciplinary field that deals with the synthesis, structural characterization and properties of various solids, and it has been playing a more and more important role in the design and preparation of advanced materials. This book includes the excellent research results recently obtained by a wide spectrum of solid state chemists both from China and from abroad. Among the distinguished contributors are C N R Rao, M Greenblatt and Y T Qian, to name a few. A variety of subjects representing the frontiers of solid state chemistry — which are categorized into solids with electrical, optical and magnetic properties; porous solids and catalysts; hybrid inorganic-organic solids; solid nanomaterials; and new synthetic methods and theory — are presented. This book will benefit readers who are interested in the chemistry and physics of solids, as well as materials scientists and engineers.The proceedings have been selected for coverage in:• Chemistry Citation IndexTM• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)

Book Description
The search for alternative nuclear fuels, materials suitable for nuclear waste repositories, and new superconducting materials has been underway for decades. We have explored metal flux and mixed-metal flux synthesis and supercritical hydrothermal synthesis to grow bulk crystals of compounds with potential for such applications. Metal and mixed-metal flux synthesis uses an excess of a low-melting metal or metal mixture as a solvent for crystal growth. Reactants are able to dissolve in the flux and create chemical bonds with one another as well as with the flux itself. A new arc melter has been built to premelt some of the starting materials. In this work, six new compounds have been grown from metal fluxes: two borides with Al substitution on the V sites (UV0.43Al0.57B4), and four structurally related stuffed superstructures: U8Al19Si6 (cubic), U8Al19Si6 (tetragonal), Np8Al19Si6 (tetragonal), and Pu8Al19Si6 (tetragonal). Supercritical hydrothermal reactions were carried out in a high pressure/high temperature superalloy autoclave. The supercritical water provides counterpressure on the thermally expanding sealed reaction ampules within. UO2 crystals approaching 2 mm in diameter have been grown from the supercritical reactions. These crystals have been sent to universities and national laboratories for further chemical and physical analyses.

Book Description
Chemical structure and bonding. The scope of the series spans the entire Periodic Table and addresses structure and bonding issues associated with all of the elements. It also focuses attention on new and developing areas of modern structural and theoretical chemistry such as nanostructures, molecular electronics, designed molecular solids, surfaces, metal clusters and supramolecular structures. Physical and spectroscopic techniques used to determine, examine and model structures fall within the purview of Structure and Bonding to the extent that the focus is on the scientific results obtained and not on specialist information concerning the techniques themselves. Issues associated with the development of bonding models and generalizations that illuminate the reactivity pathways and rates of chemical processes are also relevant. The individual volumes in the series are thematic. The goal of each volume is to give the reader, whether at a university or in industry, a comprehensive overview of an area where new insights are emerging that are of interest to a larger scientific audience.
