Target-preparation or preparation at materials, where electropolishing does not work: for example Lithium batteries, Fe-Cr alloys, W alloys, Hydrogen containing materials.
Examples of typicaly analytical questions:
Studying material structure and corrosion processes on Lithium batteries. Investigating micro- and nanostructure and grain orientations of alloys. Characterization of precipitate or particle distribution in those materials.
Fields of research:
Primarily, materials for programs to Renewable energy and its energy storage facilities (e.g. Lithium batteries).
