Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The first reference of its kind in the rapidly emerging field of computational approachs to materials research, this is a compendium of perspective-providing and topical articles written to inform students and non-specialists of the current status and capabilities of modelling and simulation.

Download or read book Charge and Energy Transfer Dynamics in Molecular Systems written by Volkhard May and published by John Wiley & Sons. This book was released on 2011-04-27 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 3rd edition has been expanded and updated to account for recent developments, while new illustrative examples as well as an enlarged reference list have also been added. It naturally retains the successful concept of its predecessors in presenting a unified perspective on molecular charge and energy transfer processes, thus bridging the regimes of coherent and dissipative dynamics, and establishing a connection between classic rate theories and modern treatments of ultrafast phenomena. Among the new topics are: - Time-dependent density functional theory - Heterogeneous electron transfer, e.g. between molecules and metal or semiconductor surfaces - Current flows through a single molecule. While serving as an introduction for graduate students and researchers, this is equally must-have reading for theoreticians and experimentalists, as well as an aid to interpreting experimental data and accessing the original literature.

Examples taken from nonlinear optics, viscosity and polarity sensors, and organic electronics testify to the vast range of applications. The result is a unique information source for experimentalists as well as theoreticians, from postgraduate students to researchers.
Download or read book Biological Electron Transfer Chains Genetics Composition and Mode of Operation written by G.W. Canters and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: From May 3-7,1997, the NATO Advanced Research Workshop on 'Biological Electron Transfer Chains' was organized in Tomar, Portugal. In the application for support the choice of the topic was justified as follows: "[Until recently efforts] have concentrated on the study of the structure and function of individual redox enzymes and proteins. Enough information is now available to make a start with the study of biological electron transfer (E1) at the next higher level of organization, that of the complete ET chain." The interest in the workshop was high: the majority of participants had registered before the workshop was formally announced, which illustrates the popularity of the topic within the biochemical and biophysical communities. The present volume contains a number of reports based on the lectures presented by the key speakers during the meeting. The workshop dealt with the following three themes: a) Electron transfer, which is the subject of Chapter 1. The analysis of ET at the molecular level is still fundamental for an understanding of how ET chains operate in vivo. After 40 years of research the contours of the subject are becoming clear now. b) Bacterial redox chains. This is the subject of Chapter 2. Its contents show how complicated these chains can be, often involving a number of gene clusters. Our understanding of the regulatory aspects and control mechanisms of these chains is only in its beginning.

Download or read book Electrified Interfaces in Physics Chemistry and Biology written by R Guidelli and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrified interfaces span from metaVsemiconductor and metaVelectrolyte interfaces to disperse systems and biological membranes, and are notably important in so many physical, chemical and biological systems that their study has been tackled by researchers with different scientific backgrounds using different methodological approaches. The various electrified interfaces have several common features. The equilibrium distribution of positive and negative ions in an electrolytic solution is governed by the same Poisson-Boltzmann equation independent of whether the solution comes into contact with a metal, a colloidal particle or a biomembrane, and the same is true for the equilibrium distribution of free electrons and holes of a semiconductor in contact with a different conducting phase. Evaluation of electric potential differences across biomembranes is based on the same identity of electrochemical potentials which holds for a glass electrode and which yields the Nernst equation when applied to a metal/solution interface. The theory of thermally activated electron tunneling, which was developed by Marcus, Levich, Dogonadze and others to account for electron transfer across metaVelectrolyte interfaces, is also applied to light induced charge separation and proton translocation reactions across intercellular membranes. From an experimental viewpoint, the same electrochemical and in situ spectroscopic techniques can equally well be employed for the study of apparently quite different electrified interfaces.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains important contributions from top international scientists on the-state-of-the-art of femtochemistry and femtobiology at the beginning of the new millennium. It consists of reviews and papers on ultrafast dynamics in molecular science.The coverage of topics highlights several important features of molecular science from the viewpoint of structure (space domain) and dynamics (time domain). First of all, the book presents the latest developments, such as experimental techniques for understanding ultrafast processes in gas, condensed and complex systems, including biological molecules, surfaces and nanostructures. At the same time it stresses the different ways to control the rates and pathways of reactive events in chemistry and biology. Particular emphasis is given to biological processes as an area where femtodynamics is becoming very useful for resolving the structural dynamics from techniques such as electron diffraction, and X-ray and IR spectroscopy. Finally, the latest developments in quantum control (in both theory and experiment) and the experimental pulse-shaping techniques are described.
