Electrochemistry can be broadly defined as the study of charge-transfer phenomena. As such, the field of electrochemistry includes a wide range of different chemical and physical phenomena. These areas include (but are not limited to): battery chemistry, photosynthesis, ion-selective electrodes, coulometry, and many biochemical processes. Although wide ranging, electrochemistry has found many practical applications in analytical measurements. The field of electroanalytical chemistry is the field of electrochemistry that utilises the relationship between chemical phenomena which involve charge transfer (eg: redox reactions, ion separation, etc.) and the electrical properties that accompany these phenomena for some analytical determination. This book presents the latest research in this field.
