prof. Ing. Martin Trunec, Dr.

Institute of Materials Science and Engineering

The examination of the theoretical knowledge assessment and its practical application will take the form of a 30-minute presentation with a discussion on advaced ceramic topics close to the doctoral dissertation's goals.

Programme D-MAT-P: Materials Sciences, Doctoral
branch ---: no specialisation, 0 credits, recommended course

20 hours, optionally

Depending on the number of participants, the course will take the form of lectures (more than five students) or consultations.  At the end of the course the doctoral student will prepare a thematic presentation in the field of advanced ceramic materials.
