Hydrophilic and Hydrophobic Colloids and the Influence of Electrolytes on Membrane Potentials and Cataphoretic

I t has been recognized for some time that it is necessary to subdivide colloids into two groups, the hydrop~lic and the hydrophobic colloids, according to the influence of electrolytes on their precipitation. To the hydrophilic colloids belong among others proteins and soaps, and to the hydrophobic colloids, collodion, mastic, graphite, metal oxides, etc. The hydrophobic colloids (such as mast...

Forces between aqueous nonuniformly charged colloids from molecular simulation

NVT Monte Carlo simulation results are presented for the forces between charged colloids within the primitive model for electrolytes. The calculations show that when charged colloids have a net dipole moment, a strong attraction can arise at short separations. The attractive force is not purely electrostatic; significant contributions follow from hard-sphere collisions between the electrolyte i...

Effect of three-body forces on the phase behavior of charged colloids

Statistical-thermodynamic theory for predicting the phase behavior of a colloidal solution requires the pair interaction potential between colloidal particles in solution. In practice, it is necessary to assume pairwise additivity for the potential of mean force between colloidal particles, but little is known concerning the validity of this assumption. This paper concerns interaction between s...

Modified Mason number for charged paramagnetic colloidal suspensions.

The dynamics of magnetorheological fluids have typically been described by the Mason number, a governing parameter defined as the ratio between viscous and magnetic forces in the fluid. For most experimental suspensions of magnetic particles, surface forces, such as steric and electrostatic interactions, can significantly influence the dynamics. Here we propose a theory of a modified Mason numb...
