The first comprehensive resource on the chemistry of vanadium, Vanadium: Chemistry, Biochemistry, Pharmacology, and Practical Applications has evolved from over a quarter century of research that concentrated on delineating the aqueous coordination reactions that characterize the vanadium(V) oxidation state. The authors distill information on biological processes needed to understand vanadium effects in biological systems and make this information accessible to a wide range of readers, including chemists without extensive biological training. Building a hierarchy of complexity, the book provides a discussion of some basic principles of 51V NMR spectroscopy followed by a description of the self-condensation reactions of vanadate itself. The authors delineate reactions with simple monodentate ligands and then proceed to more complicated systems such as diols, a-hydroxy acids, amino acids, peptides, to name just a few. They revisit aspects of this sequence later, but first highlight the influence the electronic properties of ligands have on coordination and reactivity. They then compare and contrast the influences of ligands, particularly those of hydrogen peroxide and hydroxylamine, on heteroligand reactivity. The book includes coverage of vanadium-dependent haloperoxidases and model systems, vanadium in the environment, and technological applications. It also briefly covers the catalytic reactions of peroxovanadate and haloperoxidase model compounds. It contains a discussion of the vanadium haloperoxidases and the biological and biochemical activities of vanadium(V) including potential pharmacological applications. The last chapters step outside these boundaries by introducing some aspects of the future of vanadium in nanotechnology, the recyclable redox battery, and the lithium/silver vanadium oxide battery. Primary sources documented after each chapter minimize the need to search the literature, 80 illustrations provide structural information, reaction schemes, spectra, speciation diagrams, and biochemical schemes, and 22 tables present detailed information with references to primary sources. Packed with current and authoritative information, the book covers chemistry and bioinorganic vanadium chemistry in a broad and systematic manner that engenders comprehensive understanding.

Vanadium is named after Vanadis, the most aristocratic of Norse goddesses, who symbolises beauty and fertility - essential features of vanadium chemistry. It is a ubiquitous trace element, with a surprising range of biological functions. In Bioinorganic Vanadium Chemistry, Dieter Rehder addresses the major aspects of vanadium chemistry related to living organisms and the mutual impact between biological and inorganic vanadium chemistry. Topics covered include: the history, natural occurrence, distribution and impact of vanadium inorganic aspects of the function of vanadium in biological systems interaction of aqueous vanadate and vanadyl with biogenic ligands vanadium coordination compounds the vanadium-carbon bond methods of characterisation of biogenic and model vanadium systems (EPR and ENDOR for oxovanadium(IV); 51V NMR for vanadium(V); XAS) vanadium in ascidians and polychaeta worms the concentration of vanadium in the form of amavadin by Amanita mushrooms vanadate-dependent haloperoxidases vanadium and the nitrogen cycle vanadate as energiser for bacteria, and vanadophores medicinal aspectsm including the anti-diabetic potential of vanadium compounds interaction of vanadium with proteins and protein substrates vanadium and phosphate-metabolising enzymes Bioinorganic Vanadium Chemistry conveys the essential aspects of vanadium bioinorganic chemistry, making this book a valuable complement to more general bioinorganic chemistry texts and more specialized topical reviews for researchers and students alike.

Metal nanoclusters, which bridge metal atoms and nanocrystals, are gaining attention due to their unique chemical and physical properties which differ greatly from their corresponding large nanoparticles and molecular compounds. Their electronic and optical properties are of particular interest for their use in sensing, optoelectronics, photovoltaics and catalysis. The book highlights recent progress and challenges in size-controlled synthesis, size-dependent properties, characterization and applications of metal nanoclusters. Specific topics include organochalcogenolate-stabilized metal nanoparticles, water-soluble fluorescent silver nanoclusters, thiolate-protected Au and Ag nanoclusters, DNA-templated metal nanoclusters, fluorescent platinum nanoclusters and janus nanoparticles by interfacial engineering. Edited by active researchers in the area, the book provides a valuable reference for researchers in the area of functional nanomaterials. It also provides a guide for graduate students, academic and industrial researchers interested in the fundamentals of the materials or their applications.

Metal ions play key roles in biology. Many are essential for catalysis, for electron transfer and for the fixation, sensing, and metabolism of gases. Others compete with those essential metal ions or have toxic or pharmacological effects. This book is structured around the periodic table and focuses on the control of metal ions in cells. It addresses the molecular aspects of binding, transport and storage that ensure balanced levels of the essential elements. Organisms have also developed mechanisms to deal with the non-essential metal ions. However, through new uses and manufacturing processes, organisms are increasingly exposed to changing levels of both essential and non-essential ions in new chemical forms. They may not have developed defenses against some of these forms (such as nanoparticles). Many diseases such as cancer, diabetes and neurodegeneration are associated with metal ion imbalance. There may be a deficiency of the essential metals, overload of either essential or non-essential metals or perturbation of the overall natural balance. This book is the first to comprehensively survey the molecular nature of the overall natural balance of metal ions in nutrition, toxicology and pharmacology. It is written as an introduction to research for students and researchers in academia and industry and begins with a chapter by Professor R J P Williams FRS.

The chemistry of vanadium has expanded considerably in the last decade. The element is a main consitutent and focus of research on orally administered anti-diabetes therapies, catalysts for bulk preparation of organic feedstock, and primary metallic component of certain haloperoxidases and tunicate blood cells. No less important is vanadium's function in human, animal and plant nutrition, as aw contaminant of coal and petroleum, and as an often toxic pollutant in air, soil and water. This book describes several recent developments in experimental techniques for studying vanadium, new vanadium compounds and new advances in fundamental inorganic, organic and biochemical studies of vanadium, and includes applications to the enzymology, toxicology and anitcarcinogenic and insulin-enhancing abilities of vanadium compounds.

Vanadium is now known to be one of the more biologically important transition elements. This volume focuses on vanadium chemistry and biochemistry and summarizes the role of vanadium in treating diabetes, concluding with a discussion of a recent human trial study. The volume looks in particular at model compounds that mimic the chemistry of nitrogenases as haloperoxidases. It also uncovers evolutionary aspects of haloperoxidases while examining structural and sequence relationships between these compounds and acid phosphatases. Aspects of the essentiality, toxicology, and pharmacology are discussed along with insulin-mimetic compounds and their influences in cell cultures.
