摘要: This thesis concerns studies of aqueous soft matter systems, especially surfactant micelle systems.The aim has been to study the molecular arrangement and electronic structure constituents of, as well transport properties in such a system. The studied by means X-ray absorption spectroscopy (XAS) resonant inelastic (RIXS). have investigated low-frequency dielectric (LFDS) small angle scattering (SAXS) theoretical modelling. latter was based on Fick’s laws release from binary system validated experiments.The RIXS XAS measurements show bulk water influence chemical surrounding molecule molecules confined lattice. spectra are highly dependent systems. For glycine sodium polyacrylate features which unique for carboxyl carboxylate groups can thus be used fingerprinting.The LFDS SAXS strong correlation between surfactant/poly-ion apparent mobility surfactants. conclusion is line with earlier observations.By modelling predictive model obtained importance different factors further clarified.
