New Research Group MNM @ LEM

Prof. Dr.-Ing. Yolita Maria Eggeler

The new research group MNM (Microscopy of Nanoscale Structures & Mechanism (MNM)) belongs to the central laboratory for electron microscopy (LEM) at KIT. MNM uses analytical high resolution scanning and transmission electron microscopy methods, to identify the structures of new functional and structural materials. The objectives are to reveal unknown processes which govern the evolution and deformation of micro- and nanostructures and to discover relations between nano- and microstructures and functional properties. Within the excellence cluster 3D Matter Made to Order (3DMM2O) MNM works on new materials, which are engineered and printed from the nano and micro scales. MNM collaborates close with material researchers from KIT and with universities and research institutes from all over the world.
