che411 - Physical Chemistry of Surfaces and Interfaces (Complete module description)

Students familiarize themselves with complex research-related general concepts of interfacial and surface chemistry, their application in specialized experimental techniques as well as selected examples of their technical application with an emphasis on nanoscale systems.

Master of Science
On the basis of the general knowledge from the BSc. course (chemical thermodynamics, chemical kinetics, electrochemistry, basics of spectroscopy), students select 3 advanced lectures from the catalogue of physical chemistry. According to the research focus on interfacial chemistry, this subject should be represented by a minimum of 2 lectures.

PhD program Interface Science
Students select 1 to 3 lectures (3 KP each) according to interest and need and attend a colloquium (30 min pass/fail) at the end of the semester. PhD students can only select lectures that have not been part of their MSc. curriculum.

These lectures are:
