Phase Behavior of Dispersions of Hard Spherical Particles

Rheology of Dispersions of Swollen Gel Particles *

A centrifugal technique wa.'l used to determine the swelling, Q (g swollen gel/g dry polymer), of crosslinked polyacrylate gel particles in water. Both centrifultal force aRd time of centrifugation affected the magnitude of Q but under constant centrifuge conditions it was found that Q-l 'I\'as proportional to 1'0 ' /:, 1'0 being the ionic strength. The viscoelastic properties of water dispersi...

Approximate Solutions for Galvanostatic Discharge of Spherical Particles I. Constant Diffusion Coefficient

Approximate models are developed, based on second, fourth, and sixth order polynomials, that describe the concentration profile of an electrochemically active species in a spherical electrode particle. Analytical expressions are obtained that describe the way the concentration profiles, surface concentrations, and electrode utilization change during the galvanostatic discharge of an electrode p...

Dynamic electrophoretic mobility of concentrated dispersions of spherical colloidal particles. On the consistent use of the cell model.

This paper outlines a complete and self-consistent cell model theory of the electrokinetics of dense spherical colloidal suspensions for general electrolyte composition, frequency of applied field, zeta potential, and particle size. The standard electrokinetic equations, first introduced for any given particle configuration, are made tractable to computation by averaging over particle configura...

Dispersions of ellipsoidal particles in a nematic liquid crystal.

Colloidal particles dispersed in a partially ordered medium, such as a liquid crystal (LC) phase, disturb its alignment and are subject to elastic forces. These forces are long-ranged, anisotropic and tunable through temperature or external fields, making them a valuable asset to control colloidal assembly. The latter is very sensitive to the particle geometry since it alters the interactions b...
