Vsebina:
Content (Syllabus outline):

Slušatelji se podrobneje seznanijo s posameznimi rentgenskimi absorpcijskimi spektroskopskimi metodami (npr. rentgenske absorpcijske in emisijske spektroskopije, EXAFS, (mikro)XANES, mikroXRF), ki se najpogosteje uporabljajo pri karakterizaciji sodobnih funkcionalnih materialov (v kristaliničnih, nanostrukturnih ali amorfnih oblikah in v obliki tekočih sol-gelov), kot so katalizatorji, Li-ionske baterije in podobni. Predstavljene so lastnosti najpomembnejših, predvsem sinhrotronskih virov svetlobe in žarkovnih linij, ki jih posamezne spektroskopske metode izkoriščajo. Poudarek je na uporabnosti posameznih spektroskopskih metod in njihovem medsebojnem dopolnjevanju ter uporabi v in-situ ali in-operando načinu. Študentje se na realnih primerih naučijo osnov analize strukturnih lastnosti materiala.

Students are acquainted in detail with individual spectroscopic methods (e.g. X-ray absorption and emission spectroscopy EXAFS, (micro)XANES, microXRF), which are most frequently used in the characterization of materials (in crystalline, nanostructured or amorphous state, or liquids and sol-gels), as for example catalysts or Li-Ion batteries. The course presents the properties of the most important, particularly synchrotron radiation sources and experimental stations used by individual spectroscopic methods. Emphasis is placed on the applicability of individual spectroscopic methods and their complementarities and the use of these spectroscopies in-situ and in-operando. Students use real cases to learn basics of the analysis of specific material structural properties.
