More than a tool box:

We work together to push materials analytics beyond the state of the art in five investigation areas, coupling experimental characterization with materials modelling and simulation.

3D Materials Analytics

We use X-rays to non-destructively inspect the three-dimensional distribution of matter inside the object of investigation.

Electron Microscopy

We investigate our samples using high-energy electron beams to obtain images with resolution down to the atom scale.

Surface Analytics

We combine microscopic and spectroscopic techniques to monitor processes at materials surfaces.

Spectroscopy

We perform in-situ and real-time chemical, electronic and optical characterization of materials under different conditions, e.g. to identify and map different phases.
