Volume 29 gives an account of new techniques for the study of electrodes and their reactions. It extends and complements Volumes 26 and 27 of the series which provide an introductory treatment of modern electrochemical methodology and reactions. This volume covers the various branches of spectroelectrochemistry and also some recent purely electrochemical advances. In-situ spectroelectrochemical techniques are covered by chapters on infrared, Raman, EPR, ellipsometry, electroreflectance, and photocurrent spectroscopy. Ex-situ UHV experiments are treated in a separate chapter. New electrochemical directions are described in chapters on hydrodynamic methods, channel electrodes, and microelectrodes. A final chapter covers computing strategies for the on-line accumulation and processing of electrochemical data.

Every day in our life is larded with a huge number of chemical reactions on surfaces. Some reactions occur immediately, for others an activation energy has to be supplied. Thus it happens that though a reaction should thermodynamically run off, it is kinetically hindered. Meaning the partners react only to the thermodynamically more stable product state within a mentionable time if the activation energy of the reaction is supplied. With the help of catalysts the activation energy of a reaction can be lowered. Such catalytic processes on surfaces are widely used in industry. Around 90% of chemicals are produced via a heterogeneously catalyzed process where a reaction occurs on the surface of a catalyst. However, why is it generally possible that such reactions run off with the help of heterogeneous catalysis, meaning with lower activation energy than without presence of a catalyst? What happens with the energy which is released during a reaction of gas particles on surfaces? How is this energy released, when some part of the energy is transferred to the reactant and some to the chemically active surface? Which physical mechanisms play a key role in the energy transfer? These questions are summarized in the concept of the energy dissipation. To observe this energy dissipation phenomenon, we use a new method, the chemoelectronics. With this method we try to detect the released energy, induced by reactions on surfaces, via thin-layered electronic device elements. An aim of this work is to build up very sensitive chemoelectronic sensors to measure electronic excitations released during such simple reactions of molecules as adsorption and desorption and more complicated reactions as the water formation reaction. Therefore a new line of chemoelectronic sensors is developed and characterized in terms of internal photoemission and stability. Meaning the previously used aluminum (Al-AlOx-Ag) and tantalum based (Ta-TaOx-Au) metal-insulator-metal sensors (MIM) are tested and new titanium based (Ti-TiOx-Au) MIMs are developed. Additionally silicon based stepped-metal-insulator-semiconductor sensors (stepped-MIS, Si-SiOx-Au, Si-SiOx-Pt) are set up and characterized. For the characterization of the chemoelectronic sensors the process of internal photoemission is used. Both, chemical- and photoexcitation release hot charge carriers (electrons and holes). Due to the existence of excited carriers in the sensor, a current can be measured without applying a bias voltage. It will be shown that the chemo- and the photosensitivity are strongly related to each other. As a first experiment for the chemical selectivity of the detectors, a stream of excited hydrogen molecules and hydrogen atoms is used. The excitation and radical formation is produced by the interaction of ground state molecules with a hot tungsten surface according to the pioneering experiments of Irving Langmuir. Additionally, excited oxygen beams are studied in this work.

The Chemistry of Electrode Processes discusses "electrodics" or the science dealing with the transfer of an electric charge between a solid and liquid phase. This book reviews the applications of electrodics, the history of electrochemistry, and the basic definitions and concepts of the galvanic cell. This text also deals with the rate expressions associated with the different types of electrode reaction mechanism including the passing of Faradaic current, the current-voltage curve, mass transport overpotential, and the influence of surface structure on electrode processes. This book describes the electrode-solution interphase at equilibrium, the properties of such interphase, and the ways it can influence electrode kinetics. Any electrode reaction involves several steps and can be influenced by diffusion, adsorption and other parameters. The techniques to study electrode reactions and the electrode-solution interphase consists of equilibrium measurements, steady state measurement, and transient measurement. This text also describes the significant and potential uses of electrodics in technology which need less expensive equipment compared to using spectrophotometric techniques. This book is suitable chemists, for advanced students in analytical chemistry, physics, thermodynamics, and related subjects.

The mechanism of an elementary act is undoubtedly one of the most fundamental problems of chemical and, in particular, electro chemical kinetics. Although this problem has fascinated scientists for quite a long time, it was only in the late fifties and early sixties that it began to be actively investigated for charge transfer reactions. Owing to the development of new methods in the analysis of this problem, significant advancements were made in theoretical as well as experimental studies. These investigations showed that the physical mechanism of charge transfer in all processes including heterogeneous electrochemical and homogeneous chemical and bio chemical processes is basically the same. Hence, the results ob tained in the field of electrochemical kinetics are relevant to the understanding of homogeneous chemical reactions as well. This book endeavors to summarize the results of investigations carried out during the last two decades. It is based on the author's monograph "Electrode Reactions: The Mechanism of an Elementary Act" (Nauka, 1979). As compared to the first version, the book has been considerably revised and enlarged not only to include a large body of data published between 1978 and 1982, but also to analyze in detail the links between electrochemical and homogeneous, in particular enzymatic, kinetics. As a result, a new chapter has been added to the book. The change in the title reflects the fact that the material contained in the book is not restricted to an investigation of purely electrochemical problems.

Electrochemistry of Biological Molecules presents a fairly complete summary of the electrochemistry of the more important groups of nitrogen heterocyclic molecules including purines and pyrimidines and their nucleosides and nucleotides, polynucleotides and nucleic acids, pteridines, flavins, pyrroles, porphyrins, and pyridines. Topics covered range from the theory and instrumentation of electrochemistry to various biological molecules, including pteridines, isoalloxazines, flavins, and flavin nucleotides. Comprised of nine chapters, this book begins with an overview of electrochemical techniques and their use to study biological materials, followed by a discussion on the theory and instrumentation of electrochemistry, with emphasis on their significance and utility as well aa their principles and circuits. Subsequent chapters explore nitrogen heterocyclic molecules such as purines and pyrimidines and their nucleosides and nucleotides, polynucleotides and nucleic acids, pteridines, flavins, pyrroles, porphyrins, and pyridines. The electrochemistry of biologically important pyridines is considered. This monograph should be of value to electrochemists, biochemists, and biologists.
