We present a theoretical study on the effect of refractive index variations on static and dynamic light scattering in size-polydisperse suspensions of sterically and charge-stabilized colloidal particles with an internal optical structure (core-shell model) and size-dependent refractive indices.

From the scattered intensity as a function of scattering wave number, local ordering in concentrated latex dispersions in benzene is found. Fmm the combination of intensity and photon correlation experiments follows the existence of strong hydrodynamic interactions between the dispersed particles.
Hydrodynamic and colloidal interactions are explored in concentrated, charge-stabilized colloidal dispersions by measuring the dependence of rheology (e.g., low and high-shear viscosity, high-frequency viscosity, and modulus) and self-diffusivity on salt content, particle size, and concentration.
