WebThe SAXS curve of LAFs is typical for the form factor of an elongated particle, exhibiting a power-law decay at smaller angles, and shows some characteristic modulation at q = 0.9 nm −1. In addition, the corresponding pair–distance distribution function p ( r ) of the pure LAFs (presented in Figure 8 b) was determined using the GNOM program ... WebMar 29, 2024 · Small-Angle X-ray Scattering (SAXS) The small-angle scattering technique can be used to study the structure and interactions of colloidal solutions. Particularly the properties of biological macromolecules such as DNA and proteins, which may be regarded as (charged) colloids, can be determined by SAXS measurements.

Webradius of gyration is the only precise parameter which can be determined by SAXS without invoking supplementary hypotheses. 4) Shape evaluation For a monodisperse system in SAXS, the form factor f of the scatterer is defined as the value of the scatterer volume V P divided by the spherical scatterer volume V S having the same radius of gyration R G WebApr 1, 2024 · To explore dense packings of soft colloids, scattering experiments are ideal to access the structure factor. However, for soft microgels, determination of the structure factor is difficult because of the low contrast of the polymer network and potential microgel interpenetration and deformation that change the form factor contribution. Here, we … for x in array bash
