Book Description
Various aspects of electron and proton transfer in chemistry and biology are described in this volume. The joint presentation was chosen for two reasons. Rapid electron and proton transfer govern cellular energetics in both the most primitive and higher organisms with photosynthetic and heterotrophic lifestyles. Further, biology has become the area where the various disciplines of science, which were previously diversified, are once again converging. The book begins with a survey of physicochemical principles of electron transfer in the gas and solid phase, with thermodynamic and photochemical driving force. Inner and outer sphere mechanisms and the coupling of electron transfer to nuclear rearrangements are reviewed. These principles are applied to construct artificial photosynthesis, leading to biological electron transfer involving proteins with transition metal and/or organic redox centres. The tuning of the free energy profile on the reaction trajectory through the protein by single amino acids or by the larger ensemble that determines the electrostatic properties of the reaction path is one major issue.Another one is the transformation of one-electron to paired-electron steps with protection against hazardous radical intermediates. The diversity of electron transport systems is represented in various chapters with emphasis on photosynthesis, respiration and nitrogenases. The book will be of interest to scientists in chemistry, physics and the life sciences.

Book Description
Electron Transfer in Chemistry and Biology An Introduction to the Theory Alexander M. Kuznetsov Russian Academy of Sciences, Moscow, Russia Jens Ulstrup Technical University of Denmark, Lyngby, Denmark Electron transfer is perhaps the single most important physical event in chemical, electrochemical, photochemical, biochemical, and biophysical processes. The focus and ubiquity of electron transfer is intriguing and exciting but a coherent and comprehensive approach to this topic is at the same time a challenge. Electron Transfer in Chemistry and Biology provides a thorough and didactic approach to the theoretical basis of electron transfer phenomena. Not only does it offer a full introduction to this area and a discussion of its historical development, it also gives detailed explanations of difficult issues, for example, long-range electron transfers, stochastic and dynamic processes, and biological features. A wide variety of readers will find this volume of great interest, ranging from final year undergraduate students, postgraduate students and university lecturers, to research staff in numerous fields including medical companies, electronics industry, catalysis research and development, chemical industry and some hospitals.

Book Description
This book describes the events of primary energy transduction in life processes. Life as we know it depends on pumping protons across membranes. New tools to study the protein complexes involved has led to recent intensified progress in the field. Primary Energy Transduction in Biology focusses on recent structural results and new biophysical insights. These have been made possible by recent advances in high-resolution protein structures, in physical techniques to study reactions in real time, and in computational methods to study and refine both structures and their dynamics. Written and edited by leading experts, chapters discuss the latest key questions in cell respiration, photosynthesis, bioenergetics, proton transfer, electron transfer and membrane transport. Biochemists, biophysicists and chemical biologists will find this book an essential resource for a complete understanding of the molecular machines of bioenergetics.

Book Description
Electron transfer is the most important process to take place in natural and artificial chemical systems, playing a fundamental role, for example, in photosynthesis as well as in photography. Electron transfer reactions - oxidations and reductions - are involved in, among others, a variety of energy conversion processes, analytical methods, synthetic strategies, and information processing systems. This five-volume work is the only comprehensive yet up-to-date reference on electron transfer processes. Following a foreword by Nobel prize-winner R. A. Marcus, renowned experts from all over the world provide an interdisciplinary overview of every aspect of electron transfer including theoretical-physicochemical backgrounds, latest analytical techniques to identify, monitor and measure the rate of electron transfer, utilizing electron transfer reactions in organic synthesis and catalysis, electron transfer in the gas phase or in special heterogeneous systems such as zeolites or sensitized electrodes. Other central issues are the study of biological systems and the biomimetic electron transfer processes in artificial supramolecular systems. Finally, a complete volume is dedicated to the application of electron transfer in molecular-level electronics, imaging processes and energy conversion. Each chapter is complemented by numerous tables, formulae and illustrations providing an indispensable wealth of information. All references are cross-indexed throughout the work for easy access to this highly complex topic. Whether for quickly looking-up a keyword or as a thorough introduction to a special aspect, this is an essential handbook for everyone working in the field, from experts to postgraduates, from synthetic chemists, physicochemists or biochemists to research groups in material sciences.
