In situ SAXS analysis of the water effects on the thickness evolution of nanocellulose within bamboo fiber

In this study, in situ synchrotron X-ray experiments with wide-angle X-ray scattering (WAXS) and small-angle X-ray scattering (SAXS) detectors were performed on two pure magnesium materials produced by powder metallurgy. According to SAXS analysis, each of the two materials has a porosity of less than 0.5%. Line broadening analysis was performed on diffraction patterns collected by WAXS to analyze the dislocation evolution during material deformation. In both materials, <a>-type dislocation activities dominate the tensile deformation. The influence of grain size and texture on the different tensile behaviors of these two materials is also discussed.

Saxs Analysis

Superhydrophobic surfaces were fabricated through a nanoparticle sol-gel process in the presence of a mono-disperse latex particle. By varying precursor nanoparticle size, surfaces of varying degrees of nanoroughness but controlled macro-roughness were produced, all of which exhibited superhydrophobic properties (θwater >160°, sliding angle <10°). These were immersed in water and studied in situ using synchrotron small angle X-ray scattering where the percentage interface under wetting (in contact with liquid) was directly quantified and found to agree well with traditional Cassie equations. Wetting studies in sodium dodecyl sulphate solutions of decreasing surface tension highlighting surfaces of increased hierarchical roughness (pseudo-fractal dimension ~2.5) contained significant quantity of entrapped air even at fluid surface tensions down to 37 mN m–1.
