Topic

Students learn the theoretical background and the related application of several spectroscopic and microscopic methods including e.g. ESR, Raman, AFM, STM, SERS, TERS, SEM, etc. Several examples from the related recent research are presented in details. Students will have ability for successful application of the related measuring and data-evaluating methods too. The curse gives considerable support to earn the characterization and designer attitudes of students which then can be applied during their career in biotechnology.

Conditions for acceptance of the semester

Written tests in the practice classes should pass the criteria.

Mid-term exams

Written test covering the topics of the lectures and the seminars. The result of the first part of the written exam (Minimum Written Test) should be at least 80%. In the case of the third exam the written exam is evaluated regardless the result of the Minimum Written Test. The list of the possible questions of the Minimum Written Test is announced on the Neptun system. The result of the written exam must be above 60%. The final grade is based on results of the midterm tests and the written exam. Maximum contribution of the results of the midterm tests to the total score of the written exam is 25%. Participation on the first exam is compulsory. The result of the written test must be above 60%. The final grade is based on results of the midterm tests and the written test.
