STATIC AND DYNAMIC SCATTERING BY CONCENTRATED SYSTEMS - THEORY

Significant progress has been made concerning the understanding of sev eral aspects of microstructure and dynamics of concentrated suspension s. Among these aspects are the proper description of the small-angle p eak 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 effect s of hydrodynamic interaction on the short dynamics of charge-stabiliz ed colloids. There have been several theoretical and experimental inve stigations on possible generalizations of the Stokes Einstein relation to concentrated suspensions. Mode-coupling theory for the glass trans ition describes nearly monodisperse hard-sphere systems well, but is f ound to fail partially for other systems.
