Static and dynamic scattering by concentrated systems: theory

Significant progress has been made concerning the understanding of several aspects of microstructure and dynamics of concentrated suspensions. Among these aspects are the proper description of the small-angle peak observed in scattering from aggregating colloids, the theories for the phase behaviour of colloid-polymer mixtures as well as of binary hard-sphere suspensions and the quantitative calculation of the effects of hydrodynamic interaction on the short dynamics of charge-stabilized colloids. There have been several theoretical and experimental investigations on possible generalizations of the Stokes Einstein relation to concentrated suspensions. Mode-coupling theory for the glass transition describes nearly monodisperse hard-sphere systems well, but is found to fail partially for other systems.
