We report here a multiple-reflection type ultra-small-angle x-ray-scattering apparatus constructed according to the principle proposed by Bonse and Hart. The ultra-small-angle x-ray scattering technique enables us to investigate the distribution of solutes or particles in turbid systems, which could not be studied by the conventional light-scattering and microscopic methods. By this method, the...

The small-angle X-ray and neutron scattering, time resolved X-ray small-angle and wide-angle diffraction coupled with differential scanning calorimetry have been applied to the investigation of unilamellar and multilamellar dimyristoylphosphatidylcholine (DMPC) vesicles in sucrose buffers with sucrose concentrations from 0 to 60%. Sucrose buffer decreased vesicle size and polydispersity and inc...

The certification of a new standard reference material for small-angle scattering [NIST Standard Reference Material (SRM) 3600: Absolute Intensity Calibration Standard for Small-Angle X-ray Scattering (SAXS)], based on glassy carbon, is presented. Creation of this SRM relies on the intrinsic primary calibration capabilities of the ultra-small-angle X-ray scattering technique. This article descr...

This article briefly introduces the fundamental principles of nanoparticle size distribution measurements using Small Angle X-ray Scattering, as well as data processing using the dividing distribution function. The study also investigates the existing methods of data processing. This article also discusses the testing of 2D, 3D nanostructure and Small Angle X-ray Scattering testing used in cosm...
