چکیده

A pinhole-type two-dimensional ultra-small-angle X-ray scattering set-up at a so-called medium-length beamline at SPring-8 is reported. A long sample-to-detector distance, 160.5 m, can be used at this beamline and a small-angle resolution of 0.25 µm(-1) was thereby achieved at an X-ray energy of 8 keV.

Multi-speckle X-ray photon correlation spectroscopy in the ultra-small-angle X-ray scattering range

Multi-speckle X-ray photon correlation spectroscopy (XPCS) measurements in the ultra-small-angle range are performed using a long pinhole collimation instrument in combination with two-dimensional photon-counting and high-sensitivity imaging detectors. The feasibility of the presented setup to measure dynamics on different time and length scales pertinent to colloidal systems is shown. This set...

Ultra-small-angle neutron scattering with azimuthal asymmetry

Small-angle neutron scattering (SANS) measurements from thin sections of rock samples such as shales demand as great a scattering vector range as possible because the pores cover a wide range of sizes. The limitation of the scattering vector range for pinhole SANS requires slit-smeared ultra-SANS (USANS) measurements that need to be converted to pinhole geometry. The desmearing algorithm is onl...

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....

Ultra-small-angle x-ray-scattering study: preliminary experiments in colloidal suspensions.

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...

Study on Mechanical and microcrystalline on hybrid nanocomposites by WAXS

The aim of this work is to probe the influence of nanoclay and turmeric spends content on microcrystalline of vinyl ester hybrid nanocomposites. A series of vinyl ester hybrid nanocomposites have been fabricated with varying amounts of TS viz., 0, 2.5, 5, 7.5 and 10 % w/w along with 2% nanoclay. The microcrystalline parameters such as crystallite size and lattice strain of vinyl ester hybrid na...
