Examination dates Schedule

Annotation -

The target of this subject is to make students familiar with modern approach to the description and optimisation of the electrochemical processes. The subject is based on the knowledge gained in the basic course of chemical engineering and physical chemistry. This knowledge is applied to the problems of technical electrochemistry.
