Advanced course on electrochemistry with an emphasis on the principles of electrochemical measurements at the electrode-electrolyte interface. Thermodynamics, kinetics and mechanistic issues are being discussed. Course presents the electrochemical response of real systems emphasizing the effects of adsorption and heterogeneous processes on the measured quantities. Course is focused on the admittance and impedance measurements in addition to basic electrochemical methods, electrochemical instrumentation and mathematical simulation of the electron transfer processes. Finally, spectroelectrochemical techniques, electrochemical atomic force microscopy and scanning tunneling microscopy techniques are presented. Prerequisites include physical chemistry course and knowledge of theories of electrolytes.
