Bioelectrochemistry of Biomembranes and Biomimetic Membranes
John Wiley & Sons Inc (Verlag)
978-1-119-27105-5 (ISBN)
• Describes the essential electrochemical basics required to understand why and how electrochemical and electrophysiological tools are fundamental in elucidating the mode of ion transport across biomembranes
• Requires only basic physical chemistry and mathematics to be understood, without intermediate stumbling blocks that would discourage the reader from proceeding further
• Develops contents in a step-by-step approach that encourages students and researchers to read from beginning to end
Rolando Guidelli obtained his degree in Chemistry at Florence University, Italy, and was appointed by Florence University as a lecturer in Electrochemistry. He was then promoted to full professor of Electrochemistry in the Faculty of Science of Florence University. His scientific interests have been focused on electrode kinetics, structure of the metal/water interface and bioelectrochemistry. He has won several distinguished prizes in the field of electrochemistry and is the author and editor of several book chapters on the topic. Further, he has served as the organizer of several conferences in the field.
