X-ray scattering
Using advanced X-ray scattering techniques, we study a long range of functional and structural materials. The laboratory consists of two setups for X-ray scattering and diffraction, and one for X-ray imaging.
Research activities
- Structure-properties relations in soft-condensed matter, mainly conjugated polymers and liquid crystals for organic electronics.
- Raster scanning WAXS and SAXS measurements of thin films and fibres.
- Studies of catalytic nanoparticles ex situ and under working conditions by incoherent and coherent X-ray scattering.
- Modeling of grazing-incidence small and wide angle X-ray scattering (GISAXS/GIWAXS).
- Micro- and mesoscale transport during unconstrained dendritic growth.
- Pattern selection and interfacial instabilities in regular eutectic solidification microstructures.
- Microstructure formation and chemical modification in irregular eutectic systems.
- Convective-diffusive interaction during nonequilibrium transport in metal solidification processes.
- Recrystallisation kinetics in ultrafine grained metals.
Experimental setups
- GAXS "General Angle X-ray Scattering" dual-source micro-focus setup
- High flux X-ray source; rotating anode
- Reflectometer w/1D-collimating multilayer mirror from Xenocs.
- 4-circle diffractometer, for studies of multilayer films using grazing incidence. Can also be used for powder and fibre diffraction in non-standard geometries.
- Ultra-fine-focus X-ray imaging
- Primarily for radiographic microimaging.
The group is actively participating in national and European research projects, such as FME Solar Cell, ColdWear, SUP Improvement, Nasjonal Forskerskole (Nanoteknologi for Mikrosystem), NFR 3D X-ray Coherent Diffraction Imaging of Working Catalyst Nanoparticles, ESA MAP XRMON and FP7 MIntWeld.
