Kristallogrpahie & Geomaterialforschung
.
We
investigate the atomic structure of crystalline materials. The
combination of experimental methods and simulation-based analysis
approaches helps us to understand complex materials. We are
inspired by naturally occurring atomic structures in geomaterials
to un-derstand the relationship between short- and long-range
ordering phenomena, structure-property relationships, host-guest
interactions, and formation pro-cesses of distinct materials. We
are part of the Resarch Faculty MARUM
and the MAPEX
Center for Materials and Processes.
Studied Materials:
We are interested in crystalline materials with complex local atomic structures. This includes minerals occurring in the earth’s crust as well as synthetically produced compounds, especially microporous mate-rials (zeolites and metal-organic frame-works) and mullite¬type compounds.
