Small-angle x-ray diffraction
Webb1 jan. 2016 · Wide-Angle X-ray Scattering is the same technique as Small-Angle X-ray Scattering (SAXS): only the distance from sample to the detector is shorter and thus diffraction maxima at larger angles are observed. Depending on the measurement instrument used, it is possible to do WAXS and SAXS in a single run (Small- and Wide … Webb1 apr. 2016 · The chapter describes two X-ray diffraction (XRD) techniques that are commonly used in the characterization of the structure and morphology in polymers and polymer composites. The first is wide-angle X-ray scattering (WAXS) methods for determining crystal structure, disorder, and orientation. The second is small-angle X-ray …
