Research:

The research of Andreas Schiener focusses on the very early stages of formation and growth of both quantum dots and noble metal nanoparticles in solution. To get an insight into these early stages (10µs- 20ms) a free liquid jet setup suitable to access both SAXS and WAXS pattern was developed. This setup converts the length scale into a time scale and allows the acquisition of high quality scattering data due to the decoupling of the exposure times and the time resolution.

The goal of this project is to get a fundamental understanding of the mechanisms of nanoparticle formation and growth both for the development of the particle morphology (SAXS) and the crystalline structure (WAXS)
