Small-angle X-ray scattering (SAXS) and Nuclear Magnetic Resonance (NMR) are established methods to analyze the structure and structural transitions of biological macromolecules in solution. Both methods are directly applicable to near-native macromolecular solutions and allow one to study structural responses to physical and chemical changes or ligand additions. Whereas SAXS is applied to eluc...

Solution structures of nucleosomes containing a human histone variant, H2A.Z.1, were measured by small-angle X-ray and neutron scatterings (SAXS and SANS). SAXS revealed that the outer shape, reflecting the DNA shape, of the H2A.Z.1 nucleosome is almost the same as that of the canonical H2A nucleosome. In contrast, SANS employing a contrast variation technique revealed that the histone octamer ...

MCC was made from cotton linter using mild acid hydrolysis in 2.5 M solution of HCl at 105° for 1 hour. For the SAXS experiments, MCC powder was immersed in distilled water, ethanol, and acetone about 3 weeks prior to the measurements. Also, dry MCC powder was measured using SAXS to be able to compare the MCC-solvents with the dry state. The previously done wide-angle x-ray scattering (WAXS) st...

X-ray crystallography and small-angle X-ray scattering (SAXS) in solution have been used to show that a mutant aspartate transcarbamoylase exists in an intermediate quaternary structure between the canonical T and R structures. Additionally, the SAXS data indicate a pH-dependent structural alteration consistent with either a pH-induced conformational change or a pH-induced alteration in the T t...

Structural characterisations using the SAXS technique in a number of nanoheterogeneous materials and liquid solutions are reviewed. The studied systems are protein (lysozyme)/water solutions, colloidal ZnO particles/water sols, nanoporous NiO-based xerogels, hybrid organic-inorganic siloxane-PEG and PPG nanocomposites and PbTe semiconductor nanocrystals embedded in a glass matrix. These investi...

Carbonisation is one of the important methods to improve utilisation coal. The structural composition coal plays an role in carbonisation. This work used small-angle X-ray scattering (SAXS) investigate pore structure three kinds raw coals with different carbon content derived from Xingtai City, Hebei Province, China. structures corresponding cokes obtained through carbonisation at 1200°C were i...
