This book was released on 2012-12-06 with total page 647 pages. Available in PDF, EPUB and Kindle. Book excerpt: The papers in this book were presented at the Third International Symposium on Redox Mechanisms and Interfacial Properties of Molecules of Biological Importance held in Honolulu, Hawaii between October 19-23, 1987. This Symposium was held as part of the 172nd Meeting of The Electrochemical Society which was cosponsored by The Electrochemical Society of Japan with the cooperation of The Japan Society of Applied Physics. The aim of the Symposium was to bring together a group of electrochemists and bio-medical scientists with interests in electrochemistry from around the world to present their most current research results and/or to present up-to-date reviews of current areas of research activity. It is quite clear from the diversity of topics covered in the various papers that electrochemistry and electrochemical techniques and principles have much to contribute to our under standing of many important biochemical phenomena. For example, electrochemical studies are providing important insights into the redox properties of biomolecules ranging from relatively small organic molecules such as indoleamine neurotransmitters to very large organic/organometallic molecules which include various redox enzymes or model enzyme systems. Many of the most powerful analytical techniques are now being coupled to electrodes to monitor potential-controlled behaviors of bio logical molecules at charged interfaces. Electrochemical techniques are now being developed which permit extraordinarily small electrodes to be inserted into single cells to monitor electroactive biomolecules. Other microelectrodes are being employed to control cell growth and to manipulate single cells.

Available in PDF, EPUB and Kindle. Book excerpt: There is no doubt that the field of artificial membrane transport using synthetic ionophores has advanced remarkably in the past 15 years due primarily to the synthesis of new ionophores. Even though the theoretical framework substantially predated this activity, the merging of theory with transport experiment has often been sketchy. The purpose of this outline has been to examine key examples to illustrate the underlying principles and to suggest how experimental variables dominate the results obtained. To a very good approximation the assumption of a "diffusion" regime is often justified, is easily confirmed experimentally and provides a clear framework for exploitation of the inherent selectivity of a given ionophore. Thus for synthetic chemists who wish a "quick and nasty" experiment to examine the question of selectivity, the recipe is clear: a mixture containing all ions of interest in a standard experiment for each ligand of interest using a moderately stirred (100-200 rpm) cell and analysis of the mixture produced on the OUT side of the cell at a fixed, small extent of transport. Together with duplicates and controls, this modest set of experiments will place the results on an unambiguous footing from which clear conclusions about each ionophore's characteristics are readily obtained. For those with more detailed interests in the transport process the demands are correspondingly higher.
Download or read book Handbook of Chemical and Biological Sensors written by R.F Taylor and published by CRC Press. This book was released on 1996-01-01 with total page 1248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Chemical and Biological Sensors focuses on the development of sensors to recognize substances rather than physical quantities. This fully inclusive book examines devices that use a biological sensing element to detect and measure chemical and biological species as well as those that use a synthetic element to achieve a similar result. A first port of call for anyone with a specific interest, question, or problem relating to this area, this comprehensive source of reference serves as a guide for practicing scientists and as a text for many graduate courses. It presents relevant physics to chemists, chemistry to materials scientists, materials science to electronic engineers, and fabrication technology to all of the above. In addition, the handbook is useful both to newcomers and to experienced researchers who wish to broaden their knowledge of the constituent disciplines of this wide-ranging field.

Download or read book Photochemical Conversion and Storage of Solar Energy written by E. PELIZZETTI and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 652 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book collects the lectures and the status reports delivered during the "Eighth International Conference on Photochemical Conversion and Storage of Solar Energy", IPS-8, held in Palermo (Italy) from 15th to 20th of July 1990. As usual, the main theme of the Conference was that of making the point about the trends and the developments of the studies related to the photochemical exploitation of solar energy and also to report the main lines of potential applications. Therefore the contributions reflect this point; they vary from those reporting basic and fundamental theories to those reporting cases of possible applications. For the sake of following the logical line which links each other the various contributions, we report the six areas in which the main theme of the conference was devided: (a) Electron and energy transfer in homogeneous and heterogeneous systems; (b) Photosynthesis: organized assemblies and biomimetic systems; (c) Photoelectrochemistry; (d) Photocatalysis: homogeneous and heterogeneous regime; (e) Environment: photochemical and photocatalytic processes; (f) Solar energy materials and photochemical engineering. It remains now to thank persons and institutions which made possible the organization of the Conference. The persons to thank are all the members of the International and National Organizing Committees and in particular Prof. A.Sclafani and Dr. L.Palmisano whose efforts were essential for the success of the Conference.

This book was released on 2013-06-29 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present volume presents six chapters, two of them fairly brief, covering both fundamental and applied electrochemistry. The latter aspect has, of course, historical significance in the subject as well as a major technological profile in recent decades, while intimate connections between these complementary facets of the subject have always been a driving force for its earlier and continu ing development. In the Modern Aspects of Electrochemistry series we have periodically included contributions from the several schools of Russi~n electrochemistry. This approach is continued in the present volume by inclusion of the chapter by Benderskii, Brodskii, Daikhin, and Velichko from the Frumkin Institute, Moscow, on phase transitions among molecules adsorbed in the double-layer interphase at electrodes. This topic has attracted attention for some years through the works of the Russian school and of Gierst and Buess-Herman. Such behavior is also related to the important phenomenon of self-assembly of molecules in films at interfaces. In Chapter 1, these authors give an account of the factors associated with two-dimensional phase transitions and associated orientation effects with polar adsorbates at electrode interfaces. The theoretical interpretation of these effects are also treated in some detail. Chapter 2, by Rusling, deals with electrochemistry and electro catalysis in microemulsions, thus connecting aspects of electrode kinetics, adsorption at electrode interfaces, and colloid chemistry.

Available in PDF, EPUB and Kindle. Book excerpt: The dream of developing a biocomputer should not be dismissed as a sheer fantasy. Although there is naturally some doubt as to whether it is possible to design a computer using carbon-based components as in living organisms, instead of silicon-based components as in existing computers, the fact that an average brain often outperforms the most sophisticated computer in terms of the complexity of tasks, if not in terms of speed, is a living testimony to this possibility. The remaining question is to what extent a biocomputer can mimic a living organism and whether it is possible to design and fabri cate such a biocomputer within the foreseeable future. This volume does not attempt to provide immediate and exact answers to these questions but instead attempts to provide a vision and a progress report of the initial efforts. This volume is mainly a collection of papers presented at the Symposium on Molecular Electronics - Biosensors and Biocomputers, sponsored by the Divi sion of Biotechnology, Health and Environment of the Fine Particle Society, held from July 19-22, 1989 at the Society's 19th Annual Meeting in Santa Clara, California. Also included are articles contributed by those who planned to attend the conference but were unable to do so. The emergence of the field of molecular electronics is largely the consequence of one person's crusade, that of Forrest L. Carter.

Download or read book Bioelectrochemistry of Biomacromolecules written by Giorgio Lenaz and published by Birkhäuser. This book was released on 2012-12-06 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioelectrochemistry: Principles and Practice provides a comprehensive compilation of all the physicochemical aspects of the different biochemical and physiological processes. Macromolecules, essentially nucleic acids, proteins and complex carbohydrates, are the building blocks of cell structure and function. This fifth volume in the "Bioelectrochemistry" series deals essentially with water-soluble biomacromolecules, since the properties of membrane-bound proteins are considered in other volumes of this series. The first chapter provides an extensive review of the structure, chemical reactivity and electromagnetic properties of nucleic acids. The following five chapters concentrate on proteins, their structure, folding and function, the electrochemistry of redox proteins and voltammetric methods. Special attention is devoted to the field of thiol/disulfide exchange as well as to one particular class of proteins, the iron-sulfur proteins. The last chapter considers the chemistry and properties of glycosaminoglycans, the complex charged polysaccharides of the cell surface and extracellular matrix. This series is intended as a set of source books for graduate and postgraduate students as well as research workers at all levels in bioelectrochemistry.
