X-ray techniques comprise a range of experimental methods that exploit the interaction of X-ray photons with matter to probe structural, electronic, and compositional properties across length scales from atomic to macroscopic. Major classes include X-ray diffraction (single-crystal, powder, and small- or wide-angle scattering) for determining crystallographic and nanoscale structure; X-ray spectroscopy (XANES, EXAFS, XPS) for probing oxidation states, local coordination, and electronic structure; and X-ray imaging and tomography for spatially resolved density and phase-contrast mapping. These techniques rely on well-characterized X-ray sources, monochromators, detectors, and often synchrotron or free-electron laser facilities to achieve high brilliance, energy tunability, temporal resolution, and quantitative analysis.
Using small angle neutron and X-ray scattering, researchers from the European Spallation Source and RWTH Aachen University have compared the nanostructure of gluten-free and normal spaghetti, finding that the kind with gluten ...
