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

在本项目中，将建立X射线对分布函数（PDF），并制定一项指南，以检测液体中的结构变化，并推导出胶体界面处溶剂分子重组层的数量和程度。胶体界面处液体结构的理解对于SFB的不同项目特别重要，其中包括固液催化或层状硅酸盐的分层。实验PDF数据应与分子动力学模拟相结合，并与表面敏感NMR光谱的结果相补充。

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.
