COURSE DESCRIPTION

Course objectives

Acquisition of theoretical knowledge about different techniques and methods for characterization of materials, and practical knowledge about the preparation of samples and the application of simple and advanced instrumental techniques and methods.

Course enrolment requirements and entry competences required for the course

 

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam, student is expected to be able to:
- optimally use numerous possibilities of individual instruments
- conclude which instrumental technique and method can be applied to determine predicted properties of materials
- properly prepare samples and adjust a instrument for a particular measurement, i.e. to calibrate the instrument
- independently carry out measurements and determine basic parameters of the measured data
