This paper reports the performance of an ultra-small-angle X-ray scattering facility on beamline X23A3 at the National Synchrotron Light Source. Based on a Bonse-Hart double-crystal design, the instrument combines: continuously tunable optics with asymmetric first monochromator crystal, high-flux ...
Ultra-small-angle X-ray scattering (USAXS) is capable of probing structural inhomogeneities in the size range of 1 to 1000 nm. Recent developments of X-ray sources and optics make USAXS increasingly relevant to polymer research. In this review, we examine the current technical state of USAXS ...
The ultra-small-angle X-ray scattering (USAXS) technique has been used to investigate and to quantify the morphology and size distribution of second-phase particles in Zircaloy-4 under various heat-treatment conditions. The alloy samples were solutionized in the β phase field at 1293K for 15mi...

We have performed a systematic investigation of the colloidal crystal formation wit the ultra-small-angle X-ray scattering (USAXS) technique. We estimated the distribution of poly(methylmethacrylate) (PMMA) latex particles i the binary colloidal dispersion of PMMA latex and polystyrene (PS) latex di...
Rice, wheat, and potato starches were investigated using ultra-small angle X-Ray diffraction (USXRD) in the range of 100–58,000 . The results showed trends consistent with the known sizes of starches. However, the observed Rg values for the scattering substances lie in the 100–300 nm ran...
