Coupling effect of solvent–colloid interaction on diffusivity and viscosity of colloidal hard-sphere suspensions: Statistical mechanical free-volume approach

Brownian Dynamics Simulations on Hard-Sphere Colloidal Suspensions

Melting and crystallization of colloidal hard-sphere suspensions under shear.

Shear-induced melting and crystallization were investigated by confocal microscopy in concentrated colloidal suspensions of hard-sphere-like particles. Both silica and polymethylmethacrylate suspensions were sheared with a constant rate in either a countertranslating parallel plate shear cell or a counterrotating cone-plate shear cell. These instruments make it possible to track particles under...

Direct observation of dynamical heterogeneities in colloidal hard-sphere suspensions

The real-space dynamics in a model system of colloidal hard spheres was studied by means of time-resolved fluorescence confocal scanning microscopy. Direct experimental evidence for the presence of dynamical heterogeneities in a dense liquid was obtained from an analysis of particle trajectories in two-dimensional slices of the bulk sample. These heterogeneities manifest themselves as a non-Gau...
