## Electrochemical methods: fundamentals and applicationsTakes the student from the most basic chemical and physical principles through fundamentals of thermodynamics, kinetics, and mass transfer, to a thorough treatment of all important experimental methods. Treats application of electrochemical methods to elucidation of reaction mechanisms; double layer structure and surface processes, and their effects on electrode processes are developed from first principles; other key features include a chapter on operational amplifier circuits and electrochemical instrumentation, unique coverage of spectrometric and photochemical experiments, and Laplace transform and digital simulation techniques. Contains numerous examples, illustrations, end-of-chapter problems, references, uniform mathematical notation, and an extensive list of symbols, abbreviations, definitions, and dimensions. |
