In X-ray crystallography, wide-angle X-ray scattering (WAXS) or wide-angle X-ray diffraction (WAXD) is the analysis of Bragg peaks scattered to wide angles, which (by Bragg's law) are caused by sub-nanometer-sized structures. It is an X-ray-diffraction method
Wide-angle X-ray scattering (WAXS) or WAXD is the most widely used method to provide information on the crystallographic structure, atomic positions, and sizes in a unit cell, and, to some extent, chemical composition as well as chemical stoichiometry.
Emanating in 3D, the X-ray diffraction signals scattered by the sample are incident on the flat X-ray detector as a function of the in-plane exit angle (α f) and out-of-plane angle (ψ), with the scattering plane being defined here by the incident and secularly reflected X-rays.
1 de ene. de 2016 · Wide-Angle X-ray Scattering (WAXS) or Wide-Angle X-ray Diffraction (WAXD) is an x-ray-diffraction technique that is often used to determine the crystalline structure of inorganic and organic polymeric membranes.

15 de jul. de 2020 · Along with other characterization techniques, grazing incidence small- and wide-angle X-ray scattering (GISAXS and GIWAXS) have played significant role in deeper understanding of film morphology. Herein, the importance of these techniques is explained with examples from various aspects of OSCs.
WAXS (Wide-angle X ray scattering): In X-ray crystallography, is the analysis of Bragg peaks scattered to wide angles, which are caused by sub-nanometer sized structure. It is used to determine the crystalline structure of the polymers.
1 de oct. de 2013 · Wide angle X-ray scattering patterns (q > 0.5 Å −1) are collected, as the name suggests, at higher angles, typically by placing a detector closer to the sample. The WAXS region contains information about the secondary structures and their rearrangements.
