prof. Ing. Martin Trunec, Dr.

Institute of Materials Science and Engineering

Knowledge of material sciences and engineering at Masters level.

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.

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

The course will provide students with the advanced physico-chemical knowledge required for experimental study in the field of structure and properties of ceramic materials and composites.
Graduate of the course will be able to apply the acquired knowledge in doctoral study of material engineering and in particular in solving dissertation work connected with research in the field of advanced structural, electroceramic and bioceramic materials.
