The long-time self-diffusivity in concentrated colloidal dispersions [PDF]

open access: yes, 1994
The long-time self-diffusivity in concentrated colloidal dispersions is determined from a consideration of the temporal decay of density fluctuations. For hydrodynamically interacting Brownian particles the long-time self-diffusivity, D^s_∞, is shown to ...
