Scanning WAXS data of peptide-based fiber. (a) View of the multi-sample holder utilized for the analysis of the fibrous specimens; the inset provides a close-up of a single fiber mounted for measurement. (b) Representative 2D WAXS pattern showing the characteristic scattering rings used for phase identification and structural analysis. (c) Detail of the central SAXS region and the corresponding 1D SAXS profile (intensity versus q), illustrating the scattering features at low angles. (d) Scanning microscopy results: the WAXS composite map and the corresponding WAXS scattering mesh, obtained after an interpolation procedure (Siliqi et al., 2016View full citation), demonstrate the spatial distribution and intensity variations of the crystalline signal across the sample surface (dimensions in mm). (e) Representative 1D WAXS profile integrated from the 2D data, showing the meridional and equatorial peaks used for the structural fingerprinting of the fiber. (f) Structural representation of (F-Dopa)3 peptide.
