Clay minerals are typically formed over long periods of time by the gradual chemical weathering of rocks, usually silicate-bearing, by low concentrations of carbonic acid and other diluted solvents. Since ancient times, clay minerals have been investigated because of their importance in agriculture, ceramics, building and other uses. In this book, the authors present current research in the study of the types, properties and uses of clay. Topics discussed include clay mineral application in electrochemistry and wastewater treatment; organoclay/polymer nanocomposites; use of clays to manufacture honeycomb monoliths for pollution control applications; clays for the removal of dyes from aqueous solutions and structural modification of montmorillonite clays by the pillaring process.

This book presents current research in the field of electrochemistry. Topics discussed include advanced materials for wet electrochemical detection of organic impurities; electrochemical applications of modified electrodes in waste water treatment and energy conversion systems; electrochemical hydrogen storage; application of high temperature electrolysis for large-scale hydrogen production; electrolysis of nitrate aqueous solution; electrocoagulation and electroflotation; and, voltage stabilisation using a storage capacitor and physical and electrochemical properties of quaternary ammonium salts.

This book includes a detailed study on the electrochemical oxidation and corrosion of metals (silver, copper and their alloys) in concentrated aqueous electrolytes solutions. The properties of the electronic subsystem of the solid electrolyte and their effect on the electrode process are discussed as well. In addition, natural and synthesised porous materials are deemed as one of the most important object of study in major contemporary technologies. The authors of this book analyse results of experimental researches revealing the regularities of high-voltage electric discharges influence in solutions of surface-active substances on the absorption processes. Moreover, reaction dynamics at the passive film/solution interface is an important subject from a theoretical and practical point-of-view. In this book, the relative importance of isovalent and oxidative dissolution is estimated, as well as anion-assisted solubilisation during oxidation of stainless alloys. Other chapters discuss non-crystalline semiconductors, crucial to a number of major technological notably in domains of electronic devices energy storage, and converters and environmental monitoring such as batteries, fuel cells and sensor technology. The structure, optical properties, electronic and ionic conduction mechanisms of non-crystalline semi-conductors are explored as well.

This book gathers the latest research from around the globe in the study in the dynamic field of electrochemistry and highlights such topics as: electrochemical applications of modified electrodes in wastewater treatment, corrosion and protection of magnesium and its alloys as a biomaterial, electrochemical hydrogen storage, analysis of electrochemical reactor performance and others.

Superconductivity is the ability of certain materials to conduct electrical current with no resistance and extremely low losses. High temperature superconductors, such as La2-xSrxCuOx (Tc=40K) and YBa2Cu3O7-x (Tc=90K), were discovered in 1987 and have been actively studied since. In spite of an intense, world-wide, research effort during this time, a complete understanding of the copper oxide (cuprate) materials is still lacking. Many fundamental questions are unanswered, particularly the mechanism by which high-Tc superconductivity occurs. More broadly, the cuprates are in a class of solids with strong electron-electron interactions. An understanding of such "strongly correlated" solids is perhaps the major unsolved problem of condensed matter physics with over ten thousand researchers working on this topic. High-Tc superconductors also have significant potential for applications in technologies ranging from electric power generation and transmission to digital electronics. This ability to carry large amounts of current can be applied to electric power devices such as motors and generators, and to electricity transmission in power lines. For example, superconductors can carry as much as 100 times the amount of electricity of ordinary copper or aluminium wires of the same size. Many universities, research institutes and companies are working to develop high-Tc superconductivity applications and considerable progress has been made. This volume brings together new leading-edge research in the field.

Over the past 25 years, the molecular electrostatic potential has become firmly established as an effective guide to molecular interactions. With the recent advances in computational technology, it is currently being applied to a variety of important chemical and biological systems. Its range of applicability has expanded from primarily a focus on sites for electrophilic and nucleophilic attack to now include solvent effects, studies of zeolite, molecular cluster and crystal behavior, and the correlation and prediction of a wide range of macroscopic properties. Moreover, the increasing prominence of density functional theory has raised the molecular electrostatic potential to a new stature on a more fundamental conceptual level. It is rigorously defined in terms of the electron density, and has very interesting topological characteristics since it explicitly reflects opposing contributions from the nuclei and the electrons.

This volume opens with a survey chapter by one of the original pioneers of the use of the electrostatic potential in studies of chemical reactivity, Jacopo Tomasi. Though the flow of the succeeding chapters is not stringently defined, the overall trend is that the emphasis changes gradually from methodology to applications. Chapters discussing more theoretical topics are placed near the end. Readers will find the wide variety of topics provided by an international group of authors both convincing and useful.

This book describes the details of the research and development of nickel-saving high nitrogen austenitic stainless steel and high nitrogen steel (HNS) with excellent corrosion resistance in the sea. This resistance was realized by using nitrogen (N), one of the ubiquitous elements, as an alloying element. By using N it is possible to save nickel (Ni), a national strategic substance in Japan, to be partially reduced or to be totally free. Not only basic information about low nickel HNS but also its promising application to bipolar plates of solid polymer fuel cells are provided. Reduction of Ni ions in the cell environment can be expected to extend the life of the fuel cell. Furthermore, there is discussion of the serendipitous application and impact of nickel-free HNS in the field of biomaterials as an anti-nickel allergy material, leading to its development for coronary stents. The book includes an explanation of how to develop extremely high corrosion-resistance steel by controlling its level of oxygen. For researchers and engineers involved in the development and evaluation of corrosion-resistant materials in particular, this book is extremely helpful for understanding the details of the development of those materials.

There is great interest in converting electricity overcapacity e.g. from renewables; from fuels such as hydrogen and synthetic gasoline; or for the conversion of nitrogen to ammonia. Solid oxide electrolysis offers a high efficiency route to these conversions utilising technology similar to solid oxide fuel cells. However, there are significant differences between electrolysis and fuel cell operation, and the fundamental aspects of electrolysis have received little attention. This Faraday Discussion brings together the research of leading scientists to address the fundamental aspects of solid oxide electrolysis. Research in this field could yield a new clean chemical industry, potentially allowing greater harvesting of renewables by storing excess energy in a more useful and higher energy density form than electricity.

This monograph will clearly depict much of the current, leading research into the reactions and properties of organic and bioorganic materials in which electron transfer plays an important role. Organic electrochemistry is increasingly expanding to various interdisciplinary fields and is of major interest to a growing number of researchers and engineers.
The contents of this book emphasize the scope of the reaction field at the electrode interface, specifically, electrogenerated active species, new mediatory reactions, and new trends in organic electrochemistry. Many of the results demonstrated in these reports may have broad applications to the development of science and new technologies.

Laser photoelectron emission not only allows investigation of interfaces between electrodes and solution, but also provides a method for fast generation of intermediate species in the vicinity of the interface and so permits study of their electrode reactions. Laser Electrochemistry of Intermediates presents the first-ever comprehensive review of this important phenomenon and its electrochemical applications.
The book explores how the innovative method of laser electron emission from metal electrodes resolves two fundamental problems inherent in current methods of intermediate species (IS) generation and detection: difficulty generating IS quickly in the vicinity of the electrode surface and low IS surface concentration. In addition, for the first time, quasi-free and solvated electrons, hydrogen atoms, simple organic and inorganic radicals, and ions with anomalous valence are systematically studied.
Laser Electrochemistry of Intermediates incorporates a unique, two-pronged analytical approach. First, the authors consider the kinetics and thermodynamics of the processes based on the participation of IS in its one-electron stages, thus allowing the assignment of real physical meaning to the electrochemical measurables. Second, they consider electrode reactions side by side with homogeneous reactions of electron transfer, facilitating understanding of the universal theory of electron transfer reactions in polar media as well as the peculiarities of these reactions occurring in the interface between electrode and solution.

Chemists increasingly apply electrochemical methods to the investigation of their systems, in particular towards a better understanding of molecular properties, the exploration of chemical reactions involving electron-transfer (ET), the initiation of further reactions by ET, the kinetic measurements, and the establishment of the reaction mechanisms, as well as the synthesis (electrosynthesis) of desired products. Trends in Molecular Electrochemistry presents recent research on procedures in molecular electroactivation and electrocatalysis, bioelectrochemistry, spectroelectrochemistry, and unconventional electrochemistry. The book highlights the state-of-the-art in the application of electrochemistry by taking an interdisciplinary approach to the study of both static and dynamic molecular properties of coordination compounds as well as inorganic, bioinorganic, and organometallic complexes, supramolecular systems, and metalloenzymes. The principles and approaches are often also valid for organic systems, which are illustrated in various contexts.
