S-centered Radicals Edited by Ben Gurion University of the Negev, Israel Sulfur containing radicals, formed from sulfur emissions from natural sources (e.g. volcanoes), power plants and from car exhausts, play an important role in our atmosphere. In the living cell, sulfur constitutes an essential part of the defence against oxidative damage and in the course of this mechanism is transformed into a variety of sulfur free radical species. S-centered Radicals deals with the organic radicals containing sulfur atoms, RS*, RSO*, RSO_2* and R_3S and the inorganic radicals, *SH and SO_x*. This is the book to bring together all the recent developments of S-centered radical chemistry. This area is extremely important to organic synthetic chemists and environmentalists. S-centered radicals are of increasing interest in biochemistry and medicine due to S-containing amino-acids and S-S bonds in proteins. Sulfur radicals are also involved in polymer chemistry and photonic materials as well as in radiation protection and nutrition. This title is the essential volume for anyone working in sulfur chemistry.

Free radicals are used as reactive intermediates in a wide range of organic syntheses as well as playing an important role in biological systems and industrial processes. Free radical chemistry is a rapidly developing area, with applications not only in chemistry but also in processes related to the environment, biology, drug research and medicine. General Aspects of the Chemistry of Radicals is an introductory book, discussing methods of formation and detection of free radicals, the rate of their reactions and their thermochemistry. The book closely examines the reactivity of free radical reactions, rate constants and temperature dependence, important in predicting the behaviour of yet unstudied systems and validating reaction mechanisms. General Aspects of the Chemistry of Radicals is written for researchers working in environmental and material sciences, organic, inorganic and physical organic chemistry. It will also be of interest to biochemists and molecular biologists working with the effects of free radicals on living systems.

Radicals play a major role as intermediates in many chemical reactions. They contribute to transformations in the atmosphere, living organisms, chemical synthesis, combustion and detonation amongst others. This comprehensive and conclusive book discusses all these aspects. N-centered Radicals deals with NOx and NCO, relatively stable radicals whose presence in the atmosphere influences the metabolism of living organisms. Also included are NHx, NCH and N3, important in radical studies, chemical synthesis, detonation and metabolism. Until now there has been no single volume bringing together all aspects of N-centered radical chemistry, from formation, to their chemistry in aqueous environments, biological systems and the atmosphere. N-centered Radicals is essential reading for researchers in organic, physical and environmental chemistry, biology and all others examining the effects of N-centered radicals.

Statistical techniques have assumed an integral role in both the interpretation and quality assessment of analytical results. In this book the range of statistical methods available for such tasks are described in detail, with the advantages and disadvantages of each technique clarified by use of examples. With a focus on the essential practical application of these techniques the book also includes sufficient theory to facilitate understanding of the statistical principles involved.

"Statistical Treatment of Analytical Data" is written for professional analytical chemists in industry, government and research institutions who require a practical understanding of the application of statistics in day to day activities in the analytical laboratory. It is also for students who require further and detailed information that may not be available directly in a typical undergraduate course.

The analysis of materials containing several elements used to be a difficult problem for analytical chemists, so a well established sequence of wet chemical qualitative tests were performed to ensure each element was detected. Quantitative tests could then be carried out on the sample, according to the range of elements present. Most analytical chemists were very familiar with these techniques, having been taugth them from a very early stage in their education and careers. The analytical chemist can now call on a range of specialist instrumental techniques which can detect the presence of many elements, often simultaneously, and often quantitatively, providing rapid results on samples which, in the past, could take days. The drawback is that the instruments tend to be expensive, suited to particular sample types or matrices and complex in both setting up and in the interpretation of results. Furthermore the general analytical chemist may have access and familiarity with only one or two methods. Written by an international team of contributors, each experts in their particular fields, this book familiarizes analytical chemists with the range of elemental analysis techniquers, to enable them to specify the most appropriate test for any given sample. In addition, it contains important chapters on sample preparation and quality control, essential elements in obtaining accurate and reliable analytical results. As such, this book will be essential reading for all analytical chemists. The techniques of elemental analysis are important in many other disciplines, so the book will be of particular interest to those commissioning a wide range of analytical measurements, such as chemists, geologists, environmental scientists and biologists. The breadth and depth of coverage will also make the book very useful for advanced students.

Peroxyl radicals are formed in biological systems, the atmosphere and aqueous waste and are important intermediates in the breakdown both of organic molecules and several inorganic species. As peroxyl radicals react with CFCs and HFCs in the atmosphere resulting in the further destruction of the ozone layer, there has been a great deal of progress towards understanding peroxyl radicals and their reactions in both the gas and liquid phase. Until now there has been no one volume which brings together all aspects of peroxyl radical chemistry — from their formation, to their wide and varied chemistry in the aqueous environment, biological systems, solid matrices, polymeric systems and the atmosphere. Peroxyl Radicals is essential reading for organic and physical organic chemists, biochemists and environmental technologists.

A comprehensive, five-book set on the chemistry of radicals This Radical Chemistry five-volume set is an essential one for students and researchers. It includes: Organosilanes in Radical Chemistry, The Chemistry of Free Radicals: Peroxyl Radicals, The Chemistry of Free Radicals: N-Centered Radicals, S-Centered Radicals, and General Aspects of the Chemistry of Radicals. Readers of the set will find a description of silyl radicals within an interdisciplinary context and learn about methods of formation and detection of free radicals. They will better understand the implications of the chemistry of peroxyl radicals, the developments of S-centered radical chemistry, and all aspects of N-centered radical chemistry.
