A physical model, which regards a colloidal dispersion as a single fluid continuum, is used to investigate cellular convection accompanying gravitational sedimentation in a hemispherical bowl with a thin cylindrical shaft along its vertical axis of symmetry. We have adapted the stream-function-vorti

A theory of sedimentation in a concentrated suspension of spherical colloidal particles proposed by Levine et al. (J. Colloid Interface Sci. 57, 424 (1976)) is further developed to derive a simple convenient expression for the sedimentation potential applicable for low zeta potentials and nonoverlap
## Abstract The simulation method presented in the previous papers is related to the concentrationโdependent sedimentationโdiffusion. It can be shown that the efficiency of the program described previously is maintained. A simulation of a system exhibiting the JohnstonโOgston effect is presented.
Photon correlation (PCS) experiments on interacting PMHA (polymethylmethacrylate) latexes show the existence of static (thermodynamic) and hydrodynamic interactions. The interactions are observed through the measurement of an effective diffusion coefficient as a function of concentration and scatter
