Attractive osmotic pressure in an electric double layer with grafted polyelectrolytes
Article Abstract:
A model of the double-layer interaction between two walls neutralized by grafted polyelectrolytes and mobile counterions and another neutralized solely by mobile counterions is examined. The grafted ions interconnect with the grafting wall through a one-dimensional potential. The model is qualitatively similar to other systems where the structures of the polyelectrolyte chains are intentionally included. Without the polyelectrolytes, the osmotic pressure is repulsive at long-range but can be attractive at medium-range depending on the configuration of the grafted ions and grafting potential.

Electrostatic models for calcium binding proteins
Article Abstract:
The binding of calcium ions to biomolecules has been studied with three continuum models based on Coulombic interactions. The refined model uses an inhomogeneous static dielectric constant but can only utilized in approximate analysis within the mean field ansatz. The primitive model generates exact solutions of the statistical mechanical problem by Monte Carlo simulations. The elementary model considers the linear thermal response and disregards steric constraints.

Ion transport in glassy polymer electrolytes
Article Abstract:
A study was conducted on ion transport in polymer electrolytes and in inorganic systems. The experiment synthesized a new family of side-group liquid crystal polymer electrolytes where mesogenic side groups impose a characteristic ultrastructure on both the polymeric molecule and, to a lesser degree, on the polyether backbone. The study presents clear evidence for the existence of decoupled ion transport in solvent-free glassy polymer electrolytes.
