Local order of solvent molecules at solid-liquid interfaces in colloidal dispersions (C07*)

• Subject Area: Analytical Chemistry ; Solid State and Surface Chemistry, Material Synthesis
• Term: from 2017 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 79971943

In this project, the X-ray pair distribution function (PDF) shall be established and a guideline be developed to detect structural changes in liquids and derive the number and extent of restructured layers of solvent molecules at colloidal interfaces. The understanding of the structure of liquids at colloidal interfaces is of particular importance for different projects of the SFB, amongst others in solid-liquid catalysis or the delamination of layered silicates. The experimental PDF data shall be combined with molecular dynamics simulations, and complemented with results from surface-sensitive NMR spectroscopy.
