Annotation -
Lectures are focused on basic understanding and description of selected experimental techniques. The individual experimental methods and their principles are discussed with respect to the application in laboratory practise. Students are expected to have solid background in physical chemistry basics including thermodynamics and kinetics of electrode processes.
