Aanbieding 1 met studiegidsnummer 4023294ENR voor alle studenten in het 2e semester met een verdiepend master niveau.
Structure determination by X-ray diffraction and structure solving/refining is the main goal of this course. A practical oriented course will be provided in which students learn how to understand, evaluate and extract all possible structural information from a diffraction pattern. Indexation, crystal parameters, powder diffraction, quantitative analysis, single crystal X-ray diffraction and texture analysis of thin films will be covered.
