Small-angle x-ray scattering study of ionomer deformation

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 of insect lipophorin.

The structure of lipophorin in insect blood (hemolymph) was investigated by a small-angle x-ray scattering method over the temperature range 0-45 degrees C. The small-angle x-ray scattering profile of lipophorin exhibited a symmetrical sphere with heterogeneous internal electron density. Cockroach and locust lipophorins, which contain hydrocarbons, demonstrated centrosymmetrical distribution of...

Ultra-small-angle X-ray Scattering

Interpretation of the Small-Angle X-ray Scattering from Swollen and Oriented Perfluorinated Ionomer Membranes

Small-angle X-ray scattering (SAXS) and bulk volumetric measurements were performed on the perfluorinated ionomer membrane “Nafion”. The swelling experiments were conducted using controlled environments of different relative humidities. The membranes were oriented using uniaxial draw, both before and after conversion of the precursor material, as well as both sequential and simultaneous biaxial...
