Electrochemistry is a well established discipline that has encompassed both applied and fundamental aspects of chemistry courses for nearly a century. In recent years, however, it has become obvious that even broader applications of this valuable technique are now available to advance knowledge and solve problems in organic, inorganic and biological chemistry. In this book, it is shown how a range of limitations that historically have restricted the use of voltammetric and related electrochemical techniques have been removed or minimised so that it is now possible to work in the gas and solid phases as well as the traditional liquid phase. Significant advances in theory, instrumentation and electrode design have also made the technique more user-friendly. The initial chapters of this book describe the basic theory and philosophy behind the modern, widespread use of voltammetric techniques. The later chapters provide examples of new areas of application and predict future possibilities for this exciting area.
