Charged colloidal solutions with short flexible counterions

Article Abstract:

Micellar-like solutions consisting of macroions with 60 negative elementary charges with short flexible counterions were studied by Monte Carlo simulations. The result reveals that the separation between the charges in a flexible dimer increases and the reduced stability is induced by counterions bridging pairs of macrions.

Monte Carlo simulation of defect-free cross-linked polyelectrolyte gels

Article Abstract:

Monte Carlo simulations were used to investigate model systems of cross-linked polyelectrolyte gels. The properties of the polyelectrolyte gels were also investigated, which revealed an increase in the gel volume for increasing charge density, decreasing cross-linking density, and increasing chain stiffness.

One-dimensional cluster growth and branching gels in colloidal system with short-range depletion attraction and screened electrostatic repulsion

Article Abstract:

Extensive numerical simulations of a simple model for charged colloidal particles in suspension with small nonadsorbing polymers are reported. The chosen effective one-component interaction potential is composed of a short-range attractive part complemented by a Yukawa repulsive tail.
