Participation in winter school at ETH Zürich with IRTG mobility grant

From Jan. 22nd to Jan. 27th 2023 a joint group from ETH Zürich and University of Zürich held the 15th winter school on light- and electron-microscopy. Awarded with a mobility grant from the IRTG, PhD candidate Niklas Wehmann was able to participate in a one-week intensive training to study the state of the art 2D and 3D electron imaging techniques. The program consisted of daily theoretical and practical units.

From the initial choosing of what sample to analyze, through the entire (complex) preparation for the various techniques, the imaging itself and lastly (3D) processing, the course covered the entire process of obtaining high quality 2D/3D image data.

With networks built and tool kits enhanced, Niklas is now eagerly looking forward to applying the new knowledge to his research within the CRC 1211. With the studied techniques he is now able to investigate the intricacies of mineralogical nanostructures even deeper, revealing some clues of how large landscapes are shaped.

The teaching staff included member of both universities as well as from the industry, while participants flew in from all of Europe or even further away.
