Download or read book Vanadium Catalysis written by Manas Sutradhar and published by Royal Society of Chemistry. This book was released on 2020-11-05 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vanadium is one of the more abundant elements in the Earth’s crust and exhibits a wide range of oxidation states in its compounds making it potentially a more sustainable and more economical choice as a catalyst than the noble metals. A wide variety of reactions have been found to be catalysed by homogeneous, supported and heterogeneous vanadium complexes and the number of applications is growing fast. Bringing together the research on the catalytic uses of this element into one essential resource, including theoretical perspectives on proposed mechanisms for vanadium catalysis and an overview of its relevance in biological processes, this book is a useful reference for industrial and academic chemists alike.

Available in PDF, EPUB and Kindle. Book excerpt: "Vanadium has, in the last two years, developed new uses, particularly in the field of redox batteries. The expanded use of vanadium reflects the complex redox-related chemistry of the element that allows it to form several oxidation states and to stabilise various chemical compounds. From the initial discovery in Mexico through to the modern day, vanadium has presented a challenge and opportunity for chemists. This volume summarises research and industrial development in understanding the chemistry of vanadium and its presence in natural and synthetic materials. This includes a review of vanadium mineralogy and occurrence in nature. The interaction with biomolecules and environmental dispersion is also discussed. Following on from this section the book delves into the application of vanadium in medical use and in power supply as well as issues related to the extraction of vanadium from its primary ores. The book has been developed by an international team of scientists and engineers with specialist interest in vanadium chemistry and use"--
Download or read book Vanadium in Biological Systems written by N.D. Chasteen and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past several decades, vanadium has increasingly attracted the interest of biologists and chemists. The discovery by Henze in 1911 that certain marine ascidians accumulate the metal in their blood cells in unusually large quantities has done much to stimulate research on the role of vanadium in biology. In the intervening years, a large number of studies have been carried out to investigate the toxicity of vanadium in higher animals and to determine whether it is an essential trace element. That vanadium is a required element for a few selected organisms is now well established. Whether vanadium is essential for humans remains unclear although evidence increasingly suggests that it probably is. The discovery by Cantley in 1977 that vanadate is a potent inhibitor of ATPases lead to numerous studies of the inhibitory and stimulatory effects of vanadium on phosphate metabolizing enzymes. As a consequence vanadates are now routinely used as probes to investigate the mechanisms of such enzymes. Our understanding of vanadium in these systems has been further enhanced by the work of Tracy and Gresser which has shown striking parallels between the chemistry of vanadates and phosphates and their biological compounds. The observation by Shechter and Karlish, and Dubyak and Kleinzeller in 1980 that vanadate is an insulin mimetic agent has opened a new area of research dealing with the hormonal effects of vanadium. The first vanadium containing enzyme, a bromoperoxidase from the marine alga Ascophyllum nodosum, was isolated in 1984 by Viltner.

Download or read book Encyclopedia of Geochemistry written by William M. White and published by Springer. This book was released on 2018-07-24 with total page 1680 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia is a complete and authoritative reference work for this rapidly evolving field. Over 200 international scientists, each experts in their specialties, have written over 330 separate topics on different aspects of geochemistry including geochemical thermodynamics and kinetics, isotope and organic geochemistry, meteorites and cosmochemistry, the carbon cycle and climate, trace elements, geochemistry of high and low temperature processes, and ore deposition, to name just a few. The geochemical behavior of the elements is described as is the state of the art in analytical geochemistry. Each topic incorporates cross-referencing to related articles, and also has its own reference list to lead the reader to the essential articles within the published literature. The entries are arranged alphabetically, for easy access, and the subject and citation indices are comprehensive and extensive. Geochemistry applies chemical techniques and approaches to understanding the Earth and how it works. It touches upon almost every aspect of earth science, ranging from applied topics such as the search for energy and mineral resources, environmental pollution, and climate change to more basic questions such as the Earth’s origin and composition, the origin and evolution of life, rock weathering and metamorphism, and the pattern of ocean and mantle circulation. Geochemistry allows us to assign absolute ages to events in Earth’s history, to trace the flow of ocean water both now and in the past, trace sediments into subduction zones and arc volcanoes, and trace petroleum to its source rock and ultimately the environment in which it formed. The earliest of evidence of life is chemical and isotopic traces, not fossils, preserved in rocks. Geochemistry has allowed us to unravel the history of the ice ages and thereby deduce their cause. Geochemistry allows us to determine the swings in Earth’s surface temperatures during the ice ages, determine the temperatures and pressures at which rocks have been metamorphosed, and the rates at which ancient magma chambers cooled and crystallized. The field has grown rapidly more sophisticated, in both analytical techniques that can determine elemental concentrations or isotope ratios with exquisite precision and in computational modeling on scales ranging from atomic to planetary.

Available in PDF, EPUB and Kindle. Book excerpt: The publication of Vanadium: Biochemical and Molecular Biological Approaches is particularly timely as it exactly coincides with the centennial anniversary of the discovery of vanadium by Professor Henze, in the blood cells of an ascidian (tunicate) collected in Gulf of Naples in 1911. Vanadium, atomic number 23, covers a wide range of oxidation states (from -2 to +5) and has unpaired electrons. Depending on these properties, a wide variety of enzymes and compounds containing vanadium have been found and the biochemical behaviour of vanadium has been investigated extensively. This monograph provides not only the basic properties and recent advances of vanadium chemistry but also presents recent topics on hyper-accumulators of vanadium, enzymatic roles of vanadium, biochemical functions of vanadium and medicinal functions of vanadium, which have been discovered by Biochemical and Molecular Biological Approaches. Vanadium: Biochemical and Molecular Biological Approaches is aimed at pure and applied chemists, biochemists, pharmaceutical and medical scientists.

This book was released on 2000-10-18 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spectrophotometry enables one to determine, with good precision and sensitivity, almost all the elements present in small and trace quantities of any material. The method is particularly useful in the determination of non-metals and allows the determination elements in a large range of concentrations (from single % to low ppm levels) in various materials.In Separation, Preconcentration and Spectrophotometry in Inorganic Analysis, much attention has been paid to separation and preconcentration methods, since they play an essential role in increasing the selectivity and sensitivity of spectrophotometric methods. Separation and preconcentration methods have also been utilised in other determination techniques.Spectrophotometric methods which are widely used for the determination of the elements in a large variety of inorganic materials are presented in the book whilst separation and preconcentration procedures combined with spectrophotometry are also described. This book contains recent advances in spectrophotometry, detailed discussion of the instrumentation, and the techniques and reagents used for spectrophotometric determination of elements in a wide range of materials as well as a detailed discussion of separation and preconcentration procedures that precede the spectrophotometric detection.
