Two transmission electron microscopes (JEOL 2100F, Topcon 002B) are in operation with a periphery comprising specimen stages for in-situ electron microscopy and electron tomography as well as a specimen preparation facility. The standard techniques of nanocharacterization are available such as high-resolution imaging, electron diffraction, electron energy-loss spectroscopy, and electron tomography. The expertise is focused on in-situ electron microscopy and electron tomography where the group\’s own research projects are carried out.
