Speaker: Debasish Saha, Juelich centre for Neutron Science (JCNS), Forschungszentrum Juelich GmbH, Germany Small-Angle Scattering (SAS) is a powerful technique that provides information about the structural organization of matter and intra- and or intermolecular interactions in the system at different external conditions. The length scales obtained from the analysis of SAS data are within the limit of a few nanometers to a few hundred nanometers. Among different SAS techniques, Small-Angle X-ray Scattering (SAXS) provides excellent resolution and shorter measurement time, enable us to study different in situ formation of nanomaterials. However, such benefits are mostly limited to high atomic number (Z) materials, whereas provides poor contrast for low-Z materials, especially for biological systems. On the other hand, the isotope labelling and solvent-contrast variation in Small-Angle Neutron Scattering (SANS) gives an excellent opportunity to extract unique information of individual components in multi-component heterogenous complexes. In addition, the magnetic moment of neutrons allows to study magnetism and magnetic materials at the nanoscale using the magnetic-SANS technique. In this talk, the basics of small-angle scattering and its applications in bio and nanomaterials will be discussed. Learn more about the RIANA project: https://riana-project.eu/
