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.

Yolita Eggeler and her research at LEM

In this interview, Yolita talks about her research of the nano cosmos of materials utilizing electron microscopy to gain a better understanding of the materials. This increased understanding allows researchers to design new materials for topics like energy, environment, mobility or health. In addition, she talks about how she benefits from being part of the Cluster of Excellence 3DMM2O and what her work means for young women who also want to go in the scientific direction.
