Learning outcomes
|
Introducing of students to the physico-chemical background of electrical phenomena and related processes at phase interfaces, with an emphasis on analytical use in currentless measurements and with the current flow. The subject reflects all modern trends, such as biosensors, environmental, eco- and green analysis, as well as food and pharmaceutical analysis.
Graduates of the course will gain an overview about modern electroanalytical chemistry, including information on the latest research results achieved by the electroanalytical group of the Department of Analytical Chemistry as a part of specialized teaching or when solving research projects.
