Limits of small angle scattering theory
Applied Optics, 1987On decrit les resultats d'une comparaison de la theorie avec les simulations de Monte Carlo. En utilisant des profils d'attenuation identiques et des fonctions de diffusion volumiques, la validite de la theorie des petits angles peut etre directement ...

1994
Small-angle X-ray scattering (SAXS) was discovered in 1938 by A. Guinier.(1) It is now a powerful method for characterizing catalysts (particle size, surface area) and disordered materials such as gels, sols, defective alloys, porous oxides or carbons, polymers.

Protein Amyloidogenesis Investigated by Small Angle Scattering
Current Pharmaceutical Design, 2016In the last decades, the study of the mechanisms inducing amyloid fibril formation has involved several experimental and theoretical biophysical approaches. Many efforts have been made by scientist at the borderline between biology, chemistry, biochemistry and physics in order to understand why and in which way a protein starts its amyloidogenic ...

Small-Angle Scattering Technique
2019This chapter provides a basic overview of SAXS and SANS techniques, which includes definitions of the basic notions, description of main properties of x-rays and neutrons, a general mathematical background which describes the physical processes in a scattering experiment, and main procedures in experimental data analysis and extraction of structural ...

Small Angle X-Ray Scattering Spectroscopy
2011Conformational changes imposed upon the Fe protein during binding and hydrolysis of Mg·ATP are key to initiating the cycle of interactions within the nitrogenase complex that result in gated electron transfer and the eventual multiple electron reduction of dinitrogen to ammonia.

Small-angle neutron scattering in lysozyme solutions
Physical Review A, 1991Small-angle neutron scattering has been performed on lysozyme solutions at different concentrations, both at the Intense Spallation Impulsed Source (ISIS), Rutherford-Appleton Laboratory) and at Orph\'ee (Laboratoire Leon Brillouin). The results show that, in addition to the large-scale structural properties revealed by light-scattering experiments ...

Small-Angle Scattering of Heterogeneous Catalysts
Journal of Applied Crystallography, 1997A heterogeneously catalyzed reaction involves the adsorption of the reactants on the surface of the catalyst. Consequently, catalytic activity is usually strongly related to the microstructural features of the catalyst. Small-angle scattering (SAS) has been extensively used to study heterogeneous catalysts and it has been shown to provide useful ...
