Integrating both theoretical and applied aspects of electrochemistry, this acclaimed monograph series presents a review of the latest advances in the field.

Number 25 of this acclaimed series breaks new ground with articles on charge transfer across liquid-liquid interfaces, electrochemical techniques to study hydrogen ingress in metals, and electrical breakdown of liquids. Also included are articles on the measurement of corrosion and ellipsometry, bringing these older subjects up to date.

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.

No. 28 of this highly regarded series explores the fundamental and applied aspects of electrochemical science. This volume features two detailed studies on the rapidly developing field of electrochemical surface science.

Volume 30 of this authoritative series provides detailed information about current advances in both fundamental and applied electrochemical research.

Prof. Jerzy Sobkowski starts off this 31st volume of Modern Aspects of Electrochemistry with a far-ranging discussion of experimental results from the past 10 years of interfacial studies. It forms a good background for the two succeeding chapters. The second chapter is by S. U. M. Khan on quantum mechanical treatment of electrode processes. Dr. Khan’s experience in this area is a good basis for this chapter, the contents of which will surprise some, but which as been well refereed. Molecular dynamic simulation is now a much-used technique in physical electrochemistry and in the third chapter Ilan Benjamin has written an account that brings together information from many recent publications, sometimes confirming earlier modeling approaches and sometimes breaking new territory. In Chapter 4, Akiko Aramata’s experience in researching single crystals is put to good advantage in her authoritative article on under- tential deposition. Finally, in Chapter 5, the applied side of electrochemistry is served by Bech-Neilsen et al. in the review of recent techniques for automated measurement of corrosion. J. O’M.

This text explores several aspects of electrochemistry. It includes a chapter on electrochemical nuclear magnetic resonance (EC-NMR) - a powerful non-invasive technique which brings insights to both fundamental and practical key aspects of electrocatalysis, including the design of better anodes for PEM fuel cells. There is also a chapter devoted to advances in the use of rigorous ab initio quantum chemical calculations in electrochemistry, addressed to all electrochemists, including those with very little prior exposure to quantum chemistry, and demonstrates the usefulness of ab initio calculations, including density functional theory (DFT) methods, to understand several key aspects of fuel cell electrocatalysis at the molecular level.The text also discusses the most important macroscopic and statistical thermodynamic models developed to describe adsorption phenomena on electrodes, including the state of the art adsorption isotherms, which are both rigorous, and in good agreement with experiment, as well as electrochemical promotion - the use of electrochemistry to activate and in situ tune the catalytic activity and selectivity of metal and metal oxide catalysts interfaced with solid electrolytes.

Topics discussed include: Solid State Electrochemistry, Kinetics of Electrochemical Hydrogen Entry into Metals and Alloys, Electrochemistry of Titanium, Electrochemical Oxidation of Organics on Synthetic Diamond-based Electrodes, Fuel Cells, Trace-Anion Catalysis of Outer-Sphere Heterogeneous Charge-Transfer Reactions, Thermodynamic and Transport Properties of Bridging Electrolyte - Water Systems Hydrogen, diamond electrodes, and fuel cells were all topics of intense interest at the 2003 ECS meeting in Paris.

It gives us pleasure in writing the Preface to this volume, in which we tried to bring together a number of stimulating and interesting people discussing physical electrochemistry. The first chapter, by Ashok Vijh, gives a remarkable account of electrochemistry as looked at from a physicist's point of view. Among the revelations of the chapter is that in a recent survey of leading areas in Science, two out of fifteen areas chosen were electrochemical and these two were the only chemical subjects chosen. In Mikhail Vorotyntsev's chapter, one finds a very modern study of the double layer, but tenuously connected with the simpler studies made in the safe harbor of mercury. In the pioneering chapter by Pons et al., one is looking at a cutting edge of electrochemistry at this time-the use of IR spectros­ copy in modes which allow the first practical determinations of the spectra of adsorbed species at the interface-an area pioneered by Pons himself. In Chapter 4, we have reached photoelectrochemistry once more, but now Tributsch speaks about what has rapidly become the major area of that topic, photoelectrocatalysis. Close to this chapter, and indeed intellectually connected with it, is that by Schmickler and Schultze about electron transfer reac­ tions at oxide-covered metal electrodes in which theories which are still relatively dubious for metal-solution surfaces are applied to complex systems involving oxides.

1.1. Definition of Terms-Thrombosis, Thromboembolic Disease, Atherosclerosis, and Blood Clotting The terms heart attack or myocardial infarction are more commonly used than thrombosis. The infarct-muscle destruction is simply the end result and thrombosis is the real cause of the heart attack. Thrombosis may be defined as the process of formation of a coalescent or agglutinated solid mass of blood components in the blood stream. Thrombi formed in either arteries or veins often cause occlusion in the vascular system and prevent blood flow. Obstruc­ to the blood vessel usually occurs at the site where the thrombi deposit. tion Furthermore, thrombi may break loose, travel through the circulating blood stream, and cause obstruction at some distal point of narrowing elsewhere. The mass or thrombus that moves is referred to as an "embolus." The two phenomena are lumped together under the term thromboembolic disease. Thrombosis that reduces blood supply to the heart is the primary factor in heart attacks.

It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M. Bockris University of Ottawa B. E. Conway Case Western Reserve University Ernest Yeager Texas A & M University Ralph E. White Preface to Volume 8 Experimental methods in electrochemistry are becoming more diverse. This volume describes many of the new techniques that are being used as well as some of the well-established techniques. It begins with two chapters (1 and 2) on electronic instrumentation and methods for utilization of microcomputers for experimental data acquisition and reduction. Next, two chapters (3 and 4) on classical methods of electrochemical analysis are presented: ion selective electrodes and polarography.

This volume of Modern Aspects contains seven chapters. The major topics covered in the first six chapters of this volume include fundamentals of solid state electrochemistry; kinetics of electrochemical hydrogen entry into metals and alloys; oxidation of organics; fuel cells; electrode kinetics of trace-anion catalysis; nano structural analysis. The last chapter is a corrected version of chapter four from Volume 35. Faisal M. AI-faqeer and Howard W. Pickering begin the first chapter by going back to 1864 and Cailletet who found that some hydrogen evolved and was absorbed by iron when it was immersed in dilute sulfuric acid. The absorption of hydrogen into metals and alloys can lead to catastrophic failures of structures. They discuss the kinetics of electrochemical hydrogen entry into metals and alloys. In chapter three, Clyde L. Briant reviews the electrochemistry, corrosion and hydrogen embrittlement of unalloyed titanium. He begins by reviewing the basic electrochemistry and general corrosion of titanium. He also discusses pitting and galvanostatic corrosion followed by a review of hydrogen embrittlement emphasizing the formation of hydrides and the effect of these on titanium's mechanical properties. Christos Comninellis and Gy6rgy F6ti discuss the oxidative electrochemical processes of organics in chapter three. They begin by defining direct and indirect electrochemical oxidation of organics. They introduce a model that allows them to distinguish between active (strong) and non-active (weak) anodes. Different classes of organic compounds are used for kinetic models of organic oxidation at active and non-active type anodes.

Number 25 of this acclaimed series breaks new ground with articles on charge transfer across liquid-liquid interfaces, electrochemical techniques to study hydrogen ingress in metals, and electrical breakdown of liquids. Also included are articles on the measurement of corrosion and ellipsometry, bringing these older subjects up to date.
