The purpose of the research was to check dynamic correlations under magnetic field in the composite type magnetorheological material consisting of polyurethane gel with embedded carbonyl-iron (CI) micrometric spheres. The onion-like sphere structure

Organogels, formed of polar and apolar glucose-based gelators with organic solvents, were studied using USAXS. The polarity was introduced by attaching the NO2 group to the gelator molecule. The USAXS data were processed using fractal analysis, pair

The results of SAXS studies are compared for two groups of samples: (i) obtained by in situ process of gelation of α-galactose-based gel with benzene as solvent, (ii) gels of various concentrations prepared from glucofuranose-based gelator with tolu

Glucofuranose-derivative based gels with various gelator concentration were studied using ultra-small angle X-ray scattering (USAXS) in the scattering vector range 0.0028–0.25 nm−1. A complex method of data processing was applied to extract the s

The process of gelation of one of the monosaccharides, α-galactose-based gelator, with benzene as a solvent, has been studied. Small-angle X-ray scattering (SAXS) synchrotron time-resolved measurements were performed throughout the gelation process.

A set of segmented polyurethanes (PU) differing in the hard-segment structure was saturated with solvents and after the equilibrium saturation was reached, put to temperature-dependent SAXS investigations. The time-resolved mode of SAXS measurements

The state of solvent in a membrane and the membrane mesostructure are of prime importance for the understanding of membrane transport phenomena. In our last SAXS (small angle X-ray scattering) study we have given evidence that the model of permeation

The main goal of the work was to examine the structural changes induced by water (D 2 O and H 2 O) in the dense cellulose film, Tomophan I, using temperature time-resolved SAXS and WAX measurements. We found that dry cellulose and water-saturated cel
