Micro- & Nanoanalytics Group

We explore and engineer materials across length scales by combining advanced electron, ion and X-ray microscopy with innovative preparation and in situ methods.

Our research focuses on understanding structure–property relationships in complex, reactive and application-relevant materials and devices, enabling the development of more reliable, efficient and sustainable technologies.

Our Research Profile

Our aim is to contribute to the development of novel materials with tailored properties as well as to the understanding and optimization of applied materials and devices. Therefore, we apply advanced and in situ light, electron and ion microscopy (TEM, SEM, FIB/SEM) in conjunction with complementary X-ray techniques in order to gain insight in the complex relationship between the material's properties on the one hand and its (local) microstructure, crystal structure and chemistry on the other.

Moreover, we utilize and develop cryo and in situ EM techniques to understand materials under application-relevant conditions as well as to measure material properties down to the nm-scale. Such materials characterization we also offer to other university groups and external collaborators.

In addition, we conduct independent materials research (deposition, synthesis, testing, operation) on novel mesoporous metal foams, 2D semiconductors as well as energy materials and devices (batteries and fuel cells).

Our research areas:

  • Scale-bridging characterization of complex, reactive and sensitive devices & sensors
  • Structure formation, phase transformations, ion transport
  • Defects and interfaces
  • Advanced methods development

The Fascination of the Microcosm: From the Light Microscope to the Scanning Electron Microscope

What appears unremarkable to the naked eye often reveals surprising details under a microscope. About a dozen 7th- and 8th-grade students from the Gesamtschule am Schießberg were able to experience this for themselves during the two-day workshop “The Fascination of the Microcosm.”
