Raman spectroscopy for investigating mass transport and concentration gradients in mixtures (A07)

• Subject Area: Synthesis and Properties of Functional Materials ; Physical Chemistry of Molecules, Liquids and Interfaces, Biophysical Chemistry
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 265191195

The project aims to resolve concentration gradients using Raman spectroscopy in order to better understand mixture-specific processes during wetting and dewetting and to provide corresponding data for modeling and simulation. In funding period 3, the investigation of transport processes in liquid mixtures will be continued in order to better understand the (de)mixing behavior of the fluid components. Various parameters (e.g. substrates, vapor pressure, temperature) will be varied. In addition, the influence of functional surfaces (e.g. structured, swellable, mesoporous) on the evaporation and transport processes will be investigated.
