Feasibility Study on Anomalous Small-Angle X-ray Scattering near Sulphur K-edge

Anomalous small-angle X-ray scattering (ASAXS) is expected to be a powerful and vital tool for the structural study of soft matter. We investigated feasibility of ASAXS near sulphur K absorption edge at SPring-8. Scattering pattern was successfully obtained and the dependence of scattering intensity on the energy of X-ray well agreed with the calculated one. This study can be the basis of struc...

Small angle x-ray scattering with edge-illumination

Sensitivity to sub-pixel sample features has been demonstrated as a valuable capability of phase contrast x-ray imaging. Here, we report on a method to obtain angular-resolved small angle x-ray scattering distributions with edge-illumination- based imaging utilizing incoherent illumination from an x-ray tube. Our approach provides both the three established image modalities (absorption, differe...

Application of small angle X-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues

ABSTRACT Background: Coherent scattering leads to diffraction effects and especially constructive interferences. Theseinterferences carry some information about the molecular structure of the tissue. As breast cancer isthe most widespread cancer in women, this project evaluated the application of small angleX-ray scattering (SAXS) for differentiation between normal and cancerous breast tissues....

Small angle X-ray scattering study on Lingula unguis shell.

Lingula unguis shell yields a diffuse small angle X-ray scattering which is caused mainly by the scattering from particles of apatite. In this study, the distribution of particles smaller than 500A was analyzed using the small angle X-ray scattering technique. The non-linear Guinier plot indicates that the shell contains various sizes of apatite particles ranging about 20-460A. The small granul...
