Research

Our research interest focusses on the local structure of colloidal particles, solvents and their interfaces. Dissolved clusters and dispersed particles interact with the surrounding solvent molecules. This can impact both, the internal structure of the particle and the molecular arrangement of the solvent molecules. In our workgroup, we look at those interfaces and local structures to understand how the local structures and the restructuring is related to macroscopic system properties.

Solvent restructuring at colloidal interfaces

Bulk solvents possess an internal structure, which changes at interfaces. We investigate the structure of solvent molecules around nanoparticles and at surfaces of mesostructured systems to understand the interaction of colloids with their environment ...more

Evolution of crystallinity in nanoparticles

The internal particle structure determines the physico-chemical particle properties, e.g. the photoluminescence. Nevertheless during nanoparticle formation, the atomic structure is not as frequently studied as the particle size itself. We run in-situ X-ray scattering experiments to get atomic insight into molecular precursors and the evolution of crystallinity during particle formation ...more

Pair Distribution Function

The pair distribution function (PDF) is a histogram of interatomic distances of the sample. It allows us to study the local and short-range order of materials, whose structures are hard to access by classical X-ray diffraction, i.e. disordered nanoparticles, glasses and liquids ...more

Experiments at synchrotron and neutron scattering facilities

High-quality PDF data is collected during beamtimes at large-scale research facilities, i.e. most frequently synchrotron radiation facilities all around the globe ...more
