Automatic sample changers not only improve the efficiency in the usage of measurement slots, they also widen the scope of scientific applications. In particular, robotic systems enable to measure large series of samples prepared by different processing routes or by varying the chemical composition. Exemplary small series of such measurements on Li-ion batteries, solar-cell or engineering ...
At the instrument BIODIFF, the incident wavelength can be freely selected between 2.7 Å and 5.6 Å. This is an essential unique feature of BIODIFF and allows it to adapt the wavelength to the unit cell size of the sample crystals. At a wavelength of 4.7 Å, unit cells with lattice constants up to 200 Å can be measured at BIODIFF. Up to now, only one other instrument in the world, MaNDi at ORNL,...
PND has proved to be particularly suitable for the study of magnetic molecular compounds and the determination of the spin density. This provides unique information on the paths of magnetic interactions and the nature of magnetic intra-or intermolecular coupling [1]. In this talk, we show on several examples how we can go beyond the spin density reconstruction and use the local susceptibility...
Using the hot source of FRM II the single crystal diffractometer (SCD) offers a high flux of unpolarized neutrons down to short wavelengths well below 1 Å, for instance at 0.55 Å. Shorter wavelengths give access to a large Q ranges, which provide very detailed/precise information, for instance, about partially disordered compounds like new materials for energy storage [e.g. G. Redhammer et...
Galectin-3 is an important protein in molecular signalling events involving carbohydrate recognition, and an understanding of the hydrogen-bonding patterns in the carbohydrate binding site of its C-terminal domain (galectin-3C) is important for the development of potent new inhibitors. I will present neutron crystal structures of galectin-3C in three states: apo, in complex with the natural...
Structural investigations on functional ceramics is an important tool for material characterisation and tailoring of properties for specialised applications. This frequently requires high angular resolu-tion to resolve highly correlated phase coexistences or subtle structural features. The most com-mon tool is high resolution X-ray or synchrotron radiation. Especially for in situ...
Historically high-resolution neutron diffractometers create the large portion of scientific output at large scale facilities. This holds true for both steady-state and pulsed neutron sources, as reflected in the publication statistics arising from monochromatic (D2B, BT1, ECHIDNA) and time-of-flight (POWGEN, HRPD, S-HRPD) high-resolution machines. Instrument SPODI fits well into the selection...
Polarized neutron single-crystal diffraction is known for studying the magnetic properties of materials. However, it is limited by the availability of intense polarized neutron resources and large crystals. New detector technologies have made high-resolution and high-efficiency large area detectors possible, which can speed up the data collection and enable more capabilities. We will report...
