Small-Angle X-Ray Scattering from Semidilute Polymer Solutions. Deuterated Polystyrene–Deuterated Cyclohexane System

Small Angle X-ray Scattering from Macromolecular Solutions and Nanoparticles

Small-angle X-ray scattering (SAXS) experiences a renaissance in the studies of macromolecular solutions allowing one to study the structure of native particles and to rapidly analyze structural changes in response to variations in external conditions [1]. Novel data analysis methods significantly enhanced resolution and reliability of structural models provided by the technique. Emerging autom...

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....

Scattering from small colloidal particles in a semidilute polymer solution

The correlations between the segments of a semidilute polymer solution are found to induce correlations in the positions of small particles added to the solution. Small means a diameter much less than the polymer’s correlation length. In the presence of polymer the particles behave as if they attracted each other. It is shown how the polymer’s correlation length may be determined from a scatter...

Ultra-small-angle X-ray Scattering

Magnetic Small Angle X-Ray Scattering

We present first experimental results of the extension of X-ray Magnetic Circular Dichroism (X-MCD) to Small Angle X-ray Scattering (SAXS). The purpose of this study is to determine size distributions and correlations lengths in the nanometer range of magnetic precipitates in granular systems. Magnetic scattering curves obtained with a GdFe system at the Gd La edge are compared with reference m...
