Digital simulation in electrochemistry

This book is an extensive revision of the earlier 2nd Edition with the same title, of 1988. The book has been rewritten in, I hope, a much more didactic manner. Subjects such as discretisations or methods for solving ordinary differential equations are prepared carefully in early chapters, and assumed in later chapters, so that there is clearer focus on the methods for partial differential equations. There are many new examples, and all programs are in Fortran 90/95, which allows a much clearer programming style than earlier Fortran versions.In the years since the 2nd Edition, much has happened in electrochemical digital simulation. Problems that ten years ago seemed insurmountable have been solved, such as the thin reaction layer formed by very fast homogeneous reactions, or sets of coupled reactions. Two-dimensional simulations are now commonplace, and with the help of unequal intervals, conformal maps and sparse matrix methods, these too can be solved within a reasonable time. Techniques have been developed that make simulation much more ancient, so that accurate results can be achieved in a short computing time.

Electrochemistry in nonaqueous solutions

A majority of chemical reactions are carried out in solution. The use of a solvent as reaction medium makes it easy to control reaction conditions such as temperature, pressure, pH, rate of mass transfer, and concentration of reactant. Water is the most popular solvent. However, by using appropriate non-aqueous solvents, substances that are insoluble in water can be dissolved, substances that are unstable in water remain stable, and chemical reactions that are impossible in water become possible. The reaction environments are markedly wider in non-aqueous solvents than in water. Most chemists are familiar with chemistry in aqueous solutions. However, the common sense in aqueous solutions is not always valid in non-aqueous solutions. This is also true for electrochemical measurements. Thus, in this book, special emphasis is placed on showing which aspects of chemistry in non-aqueous solutions are different from chemistry in aqueous solutions. Emphasis is also placed on showing the differences between electrochemical measurements in non-aqueous systems and those in aqueous systems. The importance of electrochemistry in non-aqueous solutions is now widely recognized by non-electrochemical scientists – for example, organic and inorganic chemists often use cyclic voltammetry in aprotic solvents in order to determine redox properties, electronic states, and reactivities of electroactive species, including unstable intermediates. This book will therefore also be of use to such non-electrochemical scientists.

Modern Electrochemistry Vol.1

The textbook Modern Electrochemistry by Bockris and Reddy originated in the needs of students at the Energy Conversion Institute of the University of Pennsylvania in the late 1960s. People trained in variousdisciplines from mathematics to biology wanted to understand the new high-energy-density storage batteries and the doubling of the efficiency of energy conversion offered by fuel cells over heat engines. The task was to take a group that seemed to be above average in initiative and present electrochem istry well enough to meet their needs. The book turned out to be a great success. Its most marked characteristic was—is—lucidity. The method used was to start off at low level and then move up in a series of very small steps. Repetition is part of the technique and does not offend, for the lesson given each time is the same but is taught differently.

Modern Electrochemistry Vol. 2A

Bockris and Reddy is a well-known text in the electrochemical field. Originally published in 1970, it has had a very long life as an introduction to a vast interdisciplinary area. The updating of the book should have been carried out long ago, but this task had to compete with other needs, for example, preparation of an advanced graduate text (Bockris and Khan, Surface Electrochemistry, Plenum, 1993), and while the sales of the first edition continued to be significant, the inevitable second edition remained a future project. Its time has come. It may first be restated for whom this book is intended. Its obvious home is in the chemistry and chemical engineering departments of universities. Electrochemistry is also often the basis of fields treated in departments of engineering, materials, science, and biology. However, the total sales of the first edition far exceeded the number of electrochemists in the Electrochemical Society—evidence that the book is used by scientists who may have backgrounds in quite other subjects, but find that their disciplines involve the properties of interfaces and thus, in practice, the interfacial part of electrochemistry (for the ionics part, see Vol. 1).

The CRC Handbook of Solid State Electrochemistry

The idea for this book arose out of the realization that, although excellent surveys and handbooks of electrochemistry and of solid state chemistry are available, there is no single source covering the field of solid state electrochemistry. Moreover, as this field gets only limited attention in most general books on electrochemistry and solid state chemistry, there’s a clear need for a handbook in which attention is specifically directed toward this rapidly growing field and its many applications. This handbook is meant to provide guidance through the multidisciplinary field of solid state electrochemistry for scientists and engineers from universities, research organizations, and industries. In order to make it useful for a wide audience, both fundamentals and applications are discussed, together with a state-of-the-art review of selected applications. As is true for nearly all fields of modern science and technology, it is impossible to treat all subjects related to solid state electrochemistry in a single textbook, and choices therefore had to be made. In the present case, the solids considered are mainly confined to inorganic compounds, giving only limited attention to fields like polymer electrolytes and organic sensors.
