Description

The particular innovative potential of the SFB 986 is its ability to develop macroscopic materials – structured in a multi-scale way, designed “on the drawing board”. Scattering techniques are a powerful tool to investigate these materials on several length scales.
Due to their different sensitivity to the included phases, SAXS (P07 at PETRA III, Hamburg) and SANS (SANS-1 at FRM II, Garching) were used to characterize the structure of organically linked iron oxide nanoparticle supercrystals. In addition, the self-assembling process of the coated nanoparticles and the materials behaviour during a heat treatment were studied in situ.
The results of these experiments were used to optimize the production process of the hierarchical materials system.
