This book discusses current techniques and instrumentation for cluster chemistry. It addresses both the experimental and theoretical aspects of gas-phase metal cluster reactivities, especially those pertaining to pollution removal, energetic reactions and corrosion and anticorrosion. These metal cluster systems have attracted enormous interest as they display a completely new class of physical, chemical, electronic, magnetic and catalytic properties. As these properties change with size and composition, it can thus be understood how their nature evolves from atoms to bulk solids. The book offers readers a basic understanding of the structural chemistry and reactivity of metal clusters in both gas-phase and wet chemistry. Further, the lessons they learn here regarding metal cluster chemistry will prepare researchers for the study of condensed phase dynamics that pertain to wet chemical synthesis, soft-landing deposition and cluster assembly.

This volume highlights recent progress on the fundamental chemistry and mechanistic understanding of metallocofactors, with an emphasis on the major development in these areas from the perspective of bioinorganic chemistry. Metallocofactors are essential for all forms of life and include a variety of metals, such as iron, molybdenum, vanadium, and nickel. Structurally fascinating metallocofactors featuring these metals are present in many bacteria and mediate remarkable metabolic redox chemistry with small molecule substrates, including N2, CO, H2, and CO2. Current interest in understanding how these metallocofactors function at the atomic level is enormous, especially in the context of sustainably feeding and fueling our planet; if we can understand how these cofactors work, then there is the possibility to design synthetic catalysts that function similarly.

This book provides comprehensive coverage of nanocomposite materials obtained by the sol-gel method, from synthesis to applications and including design tools for combining different properties. Sol-gel nanocomposites are of great interest in meeting processing and application requirements for the development of multifunctional materials. These materials are already commercialized for a number of applications from scratch-resistant and anti-adhesive coatings to optical materials with active and passive properties. Biomedical applications, holographic recordings, fuel cells and hydrogen storage, resists and catalysts are among the potential uses. The novel mechanical, optical and electronic properties of nanocomposite materials depend not only on the individual component materials, but also on their morphology and nanoscale interfacial characteristics. Sol-gel is a highly versatile method for obtaining both the matrix and the filler of the nanocomposite and for chemically adjusting the interface to optimize structure and properties. Although nanocomposites are widely discussed in the literature, the focus has been mainly on polymer nanocomposites. This book addresses nanocomposites based on inorganic or hybrid organic-inorganic matrices, with an emphasis on the scientific principles which are the basis for nanocomposite sol-gel synthesis and applications. A didactic approach is followed, with different topics developed from a fundamental point of view together with key examples and case studies. First comprehensive treatment of nanocomposites obtained by sol-gel methods Focuses on nanocomposites with inorganic and hybrid organic-inorganic matrices Describes design tools to optimize structure and properties for various applications Covers synthesis, processing, characterization, and modeling Uses first principles to describe the influence of interfacial characteristics on materials properties Presents case studies for both films and bulk applications Provides examples of products on the market, with descriptions of the scientific principles at the base of their success Includes contributions from recognized leaders in this multidisciplinary area.

This volume provides the reader with the most up-to-date and relevant knowledge on the reactivity of metals located in zeolite materials, either in framework or extra-framework positions, and the way it is connected with the nature of the chemical environment provided by the host. Since the first report of the isomorphous substitution of titanium in the framework of zeolites giving rise to materials with unusual catalytic properties, the incorporation of many other metals have been investigated with the aim for developing catalysts with improved performance in different reactions. The continuous expansion of the field, both in the variety of metals and zeolite structures, has been accompanied by an increasing focus on the relationship between the reactivity of metal centers and their unique chemical environment. The concepts covered in this volume are of interest to people working in the field of inorganic and physical chemistry, catalysis and chemical engineering, but also for those more interested in theoretical approaches to chemical reactivity. In particular the volume is useful to postgraduate students conducting research in the design, synthesis and catalytic performance of metal-containing zeolites in both academic and application contexts.

Zaozao Qiu shows in this thesis that transition metals can mediate or catalyze the cycloaddition or coupling reactions of carboryne with alkynes or alkenes to afford benzocarboranes, alkenylcarboranes or dihydrobenzocarboranes. These results represent powerful strategies to assemble useful complex molecules from very simple precursors in a single operation. Carboranes have many applications in medicine. However, their unique structures make derivatization difficult and the limited efficient synthetic methods to obtain functional carborane materials have restricted applications of carboranes within a narrow scope. This work breaks a new ground in metal-carboryne chemistry and will have a significant impact on synthetic, cluster and materials chemistry.

Carola Vogel's PhD thesis focuses on the synthesis, and structural and spectroscopic characterization of the first high valent iron nitride complexes. In her interdisciplinary and collaborative research Carola also describes the reactivity studies of a unique iron (V) nitride complex with water. These studies show that quantitative yields of ammonia are given at ambient conditions. High valent iron nitride and oxo species have been proposed as key intermediates in many bio-catalytic transformations, but until now these species have proven exceedingly challenging to isolate and study. Iron complexes in high oxidation states can thus serve as models for iron-containing enzymes to help us understand biological systems or aid our development of more efficient industrial catalysts.

The Landolt-Boernstein Volume 27 deals with the magnetic properties of non-metallic inorganic compounds based on transition elements, such as there are pnictides, chalcogenides, oxides, halides, borates, and finally phosphates and silicates, the latter presented in this subvolume I. A preliminary survey of the contents of all subvolumes that have already appeared or have been planned to appear is printed on the inside of the front cover. The silicates are very complex systems, intensively studied in literature. They cover large classes of minerals as well as synthetic samples. In analyzing their magnetic and magnetically related properties we essentially followed the classification given by the Mineral Reference Manual (E. H. Nickel, N. C. Nickols, Van Nostrand Reinhold, 1991). Individual chapters are dedicated to orthosilicates, sorosilicates, cyclosilicates, inosilicate, phyllosilicates and tectosilicates. Due to the huge amount of data these chapters had to be spread over several subvolumes I1, I2, etc. . - In each chapter the different groups of minerals and synthetic silicates were distinctly analyzed in various sections. For each group, additional silicate minerals, more recently reported, as well as synthetic samples having related compositions and/or crystal structures were also considered. The silicates included in each section were firstly tabulated, mentioning their compositions. The solid solutions between the end member compounds were also described. The space groups and lattice parameters for most silicates were tabulated. Crystal structures of representative silicates were discussed in more detail and the atomic positions were given.
