Insight into our work in the KIT Excellence Cluster 3DMM2O

The video shows the printing of microstructures and the examination of the samples in the scanning electron microscope (SEM). 3D microstructures are printed on a silicon chip by means of 2 photon polymerization. The further processing of the sample is done by drying by means of critical point drying. Subsequently, the sample can be attached to a SEM suitable sample holder and examined in the electron microscope. Three different printed structures are shown in the video, which will be examined in the future with regard to influencing factors such as pressure and temperature, after a pyrolysis process. Finally, the sample is prepared for the transmission electron microscope (TEM), inserted into the sample holder and introduced into the TEM.

 

Research areas

We are curios to understand how nano- and microstructures of materials form during processing and service and how they affect structural and functional properties. We presently work on single crystal superalloys (SX), high entropy alloys (HEA), functional magnetic Heusler and half Heusler (H/hH) compounds and new small-scale nano and micro engineered systems (excellence cluster 3DMM2O) on the atomic (crystals) respectively molecular (soft matter) scale.

Electron microscopy enables us to dive in into the nano-cosmos of materials and to discover yet unknown fundamental processes and materials phenomena.

Thus, we are fascinated

  • to see how plastic deformation unfolds in microstructures of high-performance metallic materials, where we aim at understanding the role of dislocations, planar faults and solute segregation to these crystal defects.
  • to directly observe solid state reactions like phase decompositions and coarsening processes in multiphase materials on the nanoscale and to explore how these processes affect functional and structural properties.
  • to explore which nano- and microstructural configurations rationalize magnetic properties and how these can be optimized.
  • to characterize Metal Organic Frameworks (MOF), to study their synthesis and to explore possible nanoscale applications.

Our group closely collaborates with national and international research partners.

Please contact us in case you are interested to collaborate. We always welcome suggestions for collaborations and our group represents a fruitful scientific environment for postdoctoral researchers from all over the world. (applications welcome)

We are looking forward to hearing from you.
