Abstract
AbstractThe structure and dynamics of silica hard spheres and charged colloidal systems has been investigated at high concentrations by means of light scattering. The index of refraction at these high volume fractions was matched using a mixture of water/isopropanol for the Yukawa particles and toluene/ethanol for the hard spheres. By simultaneously measuring the dynamic and static properties of the colloidal systems we were able to extract the hydrodynamic function H(Q) at different concentrations. Our results are in good agreement with theoretical calculations over a large concentration range.
