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 Electro chemistry 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 Ralph E. White Preface to VoluIJJe 8 The past
three decades have seen the rapid evolution of the transport
aspects of electrochemical engineering into a formal part of
electrochemistry as well as chemical engineering. With minor
exceptions, however, this subject has not been systematically
covered in any treatise or recent electrochemical text. The editors
believe that the treatment in this volume will serve the function.
In Number 20 of Modern Aspects of Electrochemistry, we present
chapters whose organization is typical for the series: They start
with the most fundamental aspects and then work to the more
complex. Thus, Jerry Goodisman gives us an interesting contribution
on a subject in which he is one of the pioneers, the electron
overlap contribution to the double layer potential difference.
Closely related to this theme, but not always imbued with knowledge
ofit, is the electron transfertheory, treated in this volume by the
experienced author A. M. Kuznetsov ofthe Frumkin Institute. H. P.
Agarwal is a well-known figure in the field of faradaic
rectification, which he originated, and he now teils us about the
more recent thinking in the field. On the other hand, Hector D.
Abruna comes relatively new to us, and his field, that of X-ray
interactions with electrodes, is new, too, but probably augers the
trend for the future. The photoelectrochemical reduction of CO2 ,
described here by Isao Taniguchi from Kumamoto University, is a
subject which will have much practical importance as the greenhouse
effect continues. Finally, alu mi nu m in aqueous solutions and the
physics of its anodic oxide is a subject which seems ever with us,
and is described in its latest guise by Aleksandar Despie and
Vitaly P. Parkhutik.

have affected progress in the field of electrochemistry, the
decision of NASA to use electrochemical auxiliary power in space
vehicles was one of the more important. Another important decision
was Ford's announcement of their sodium-sulfur cell for vehicular
use in 1969.
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.
Integrating both theoretical and applied aspects of
electrochemistry, this acclaimed monograph series presents a review
of the latest advances in the field. The current volume includes
chapters on the mechanism of nerve excitation from an
electrochemical standpoint, the electronic factor in the kinetics
of charge-transfer reaction, and five other subjects.
Covering both the theoretical and applied aspects of
electrochemistry, this well-known monograph series presents a
review of the latest advances in the field.
The present volume is comprised of six chapters covering topics
having both fundamental and substantial applied significance in
electrochemistry: ion-exchange membrane behavior, corrosion and
metal deposition, semiconductor charge injection, and the electro-
catalytic properties of carbon. In the first chapter, Verbrugge and
Pintauro examine transport models for ion-exchange membranes using
approaches from the direction of electrochemical thermodynamics of
irreversible proces- ses and others. The properties ofth~ models
are examined quantita- tively in some mathematical detail. Drazic,
in Chapter 2, gives an up-to-date account of advances in our
knowledge of the "active" dissolution of iron in corrosion
processes and the accompanying processes of H2 evolution and H
sorption. The important process of O reduction in iron corrosion 2
is also considered, together with the more controllable aspect of
anodic dissolution and cathodic deposition, as well as the
influence of anions on the dissolution kinetics of iron in aqueous
medium. An important aspect of metal plating technology is the use
of a modulated or pulsed-current regime to provide better control
over deposit morphology. In two chapters, one by Popov and Mak-
simovic and the other by Pesco and Cheh, complementary aspects of
this important technique are examined in detail: from the theo-
retical electrode-kinetic direction, taking into account the
important nonsteady diffusion situation, and from the practical
direction of examining the morphologies of electrodeposits
generated under various AC modulated or pulsed-current regimes.
This book originated out of the papers presented at the special
symposium, "Electrochemistry in Transition-From the 20th to the
21st Century," scheduled by the Division of Colloid and Surface
Science during the American Chemical Society meeting in Toronto.
The symposium was in honor of Professor J. O'M. Bockris, who
received the ACS award on "The Chemistry of Contemporary
Technological Problems" (sponsored by Mobay Corporation) during
this meeting and who also reached his 65th birthday in the same
year. The symposium was of a multidisciplinary nature and
encompassed the fields of theoretical and experimental elec
trochemistry, surface science, spectroscopy, and electrochemical
technology. The symposium also had an international flavor in that
the participants represented several countries Australia, Belgium,
Canada, Chile, England, Japan, Korea, the Netherlands, Poland,
Switzer land, Venezuela, Yugoslavia, and the United States. The
symposium was graciously sponsored by the ACS (Petroleum Research
Fund and Division of Colloid and Surface Science), Alcan
International, Dow Chemical Company, EG&G, Electrolyzer
Corporation, Exxon, General Electric Company, IBM, Institute of Gas
Technology, International Association of Hydrogen Energy, Johnson
Matthey, Inc., Kerr-McGee Corporation, Medtronics, and Texas
A&M University (Center for Electrochemical Systems and Hydrogen
Research and the Hampton Robinson Fund). The "theme" of the papers
presented at the symposium covered not only significant
contributions made to electrochemistry in the twentieth century,
but also "New Horizons in Electrochemistry" for the twenty-first
century. Thus, the scientists who presented papers were invited to
contribute chapters to this book, having the same titles as the
symposium."

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 of Electrochemistry contains six
chapters. The first four chapters are about phenomena of interest
at the microscopic level and the last two are on phenomena at the
macroscopic level. In the first chapter, Uosaki and Kita review
various theoretical models that have been presented to describe the
phenomena that occur at an electrolyte/ semiconductor interface
under illumination. In the second chapter, Orazem and Newman
discuss the same phenomena from a different point of view. In
Chapter 3, Bogus lavsky presents state-of-the-art considerations of
transmembrane potentials and other aspects of active transport in
biological systems. Next, Burke and Lyons present a survey of both
the theoretical and the experimental work that has been done on
hydrous oxide films on several metals. The last two chapters cover
the topics of the production of chlorine and caustic and the
phenomena of electrolytic gas evol ution. In Chapter 5, Hine et al.
describe the engineering aspects of the three processes used in the
chi or-alkali industry, and in Chapter 6, Sides reviews the
macroscopic phenomena of nucleation, growth, and detachment of
bubbles, and the effect of bubbles on the conduc tivity of and mass
transfer in electrolytes.
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."
No. 29 offers new insights into the energies of activation of
electrode reactions and the interfacial behavior of proteins.
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."
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.

Integrating both theoretical and applied aspects of
electrochemistry, this acclaimed monograph series presents a review
of the latest advances in the field. The current volume covers ion
and electron transfer across monolayers of organic surfactants,
determination of current distributions governed by Laplace's
equation, and three other subjects.
This volume of Modern Aspects contains a remarkable spread of
topics covered in an authoritative manner by some internationally
renowned specialists. In a seminal chapter Drs. Babu, Oldfield and
Wieckowski demonstrate eloquently the strength of electrochemical
nuclear magnetic resonance (EC-NMR) to study in situ both sides of
the electrochemical interface via the simultaneous use of and This
powerful non-invasive technique brings new insights to both
fundamental and practical key aspects of electrocatalysis,
including the design of better anodes for PEM fuel cells. The
recent impressive advances in the use of rigorous ab initio quantum
chemical calculations in electrochemistry are described in a
remarkable chapter by Marc Koper, one of the leading protagonists
in this fascinating area. This lucid chapter is 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 most important macroscopic and statistical
thermodynamic models developed to describe adsorption phenomena on
electrodes are presented critically in a concise and authoritative

contributions of Frumkin, Butler, Bockris, Guidelli and others, to
the current state of the art adsorption isotherms, which are both
rigorous, and in good agreement with experiment.
