In-situ characterization of nucleation, growth, crystallization and dissolution of nanoscaled iron oxides (A02)

项目A02利用先进的光谱和衍射技术阐明了具有明确纳米结构的金属氧化物(胶体颗粒、纳米结构薄膜)的形成、结晶和溶解的机制和动力学，以及水在这些过程中的作用。这些技术在实际实验条件下探测原子和分子的局域配位(拉曼)、它们的氧化态(XANES)、大小和形状(SAXS)、晶相(X射线衍射)和电子结构(PES)。结合儿童权利委员会其他成员的理论和实验投入，将得出有关各个过程的全面机制图景。

Project A02 elucidates the mechanisms and kinetics of formation, crystallisation and dissolution of metal oxides with well-defined nanostructure (colloidal particles, nanostructured films) and the role of water in these processes employing advanced spectroscopic and diffraction techniques. The techniques probe time-resolved under realistic experimental conditions the local coordination of atoms and molecules (Raman), their oxidation state (XANES), size and shape (SAXS), crystalline phases (XRD) and electronic structure (PES). In combination with theoretical and experimental input from other CRC members, a comprehensive mechanistic picture of the respective processes will be derived.
