Abstract

As a research scientist at the Institute of Chemistry Technology at the University of Leipzig I am currently mainly involved in research and teaching. The main focus of my scientific work in the last years and also my PhD was mainly the electron microscopic characterization of semiconducting materials and technologies, as well as porous materials and heterogeneous catalysts. I was able to gain experience in working and supervising industrial projects as well as research projects.

Materials characterization by the power of electron microscopes to image nanometer-sized objects, even down to the atomic scale, opening up the world of nanoscale materials and enabling characterization of their unique properties. Transmission electron microscopy (TEM) provides advanced analytical and high-resolution imaging techniques to support the development of innovative technologies. By means of chemical analysis utilizing energy-dispersive X-ray spectroscopy (EDS), the possibility of tomography experiments and performing in-situ heating experiments in the TEM enables remarkable developments in the field of heterogeneous catalysis. This permits investigations of the relationship between the atomic scale microstructure and electrochemical properties of, e.g., nanoparticle catalysts.
