The Small angle X-ray scattering (SAXS) is a small-angle scattering (SAS) technique where the elastic scattering of X-rays by a sample which has inhomogeneity in the nm-range. SAXS is capable of delivering structural information of polymers between 1 and 25 nm, of repeat distances in partially ordered systems of up to 250 nm. Moreover, it is capable of examining materials with short measuring time and various in-situ condition, enabling researchers to understand morphology in real time and under realistic sample environments. For these reasons, the SAXS technique have offered great opportunities to study the nanostructure and dynamic process in various materials science, such as polymer, biomolecules, liquid crystals, steels and lithium ion battery. Here, we will briefly introduce the TR-SAXS and GI-SAXS, which are common SAXS techniques available in PAL, and show practical examples of various scientific applications including various in-situ or in-operando measuring system. |
