Single GIS (Gas Injection System): Pt (Platinum).
Omniprobe Nanomanipulator.
Zeiss NanoPattering Engine ATLAS.
EDS-EBSD-System EDAX PEGASUS TEAM with Hikari-EBSD-Camera and Octane Super EDS-Detector (60mm²), 2D and 3D.
Samples/limitations:
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).
