X-ray scattering

X-ray scattering techniques are used for the structural characterization of hard and soft materials. Structural dimensions range from a few angstroms over molecular length scales to about 100 nm for supramolecular structures. Materials investigated include amorphous and crystalline solids, liquids, suspensions, gels, supramolecular assemblies and liquid crystals. A powder diffractometer in Bragg-Brentano Geometry (Bruker D8), Guinier Camera (Huber), 2-circle diffractometer (Rigaku SmartLab), a home-build instrument for small angle X-ray scattering (SAXS) and a 6-circle diffractometer for experiments on surfaces and thin films are available for the measurements. Temperature dependent measurements allow to study phase transitions and relaxation processes into thermodynamic equilibrium.
