WebbWAXS (wide-angle X-ray scattering) Based on the scattering pattern measured at the higher angles one can identify and quantify crystalline phases that are present in a given sample, as well as estimate the size of nanocrystallites. The orientation of the crystal lattice in anisotropic structures, e.g. in polymers, can be deduced from 2D WAXS ... WebbOne of the most well-known elastic scattering techniques is x-ray diffraction/crystallography, these techniques are both subsets of x-ray scattering that …

Webb1 jan. 2024 · Introduction. Small angle x-ray scattering (SAXS) is a well-established technique to investigate structural properties of materials at the nanoscale. One of the first textbooks on SAXS was already published in the 1950s [1] and another general description in the early 1980s [2]. However, due to the limited intensity of x-rays produced by ... Webb6 mars 2024 · An X-ray small-angle scattering instrument is described which is used for recording X-ray diffraction patterns or small-angle X-ray scattering curves in an angular region very close to the direct beam. ...
