The polydisperse cell model: Non-linear screening and charge renormalization in colloidal mixtures
Aldemar Torres, Gabriel Tellez, Rene van Roij
We propose a model for the calculation of renormalized charges and osmotic properties of mixtures of highly charged colloidal particles. The model is a generalization of the cell m…
Preferential interaction coefficient for nucleic acids and other cylindrical poly-ions
E. Trizac, G. Tellez
The thermodynamics of nucleic acid processes is heavily affected by the electric double-layer of micro-ions around the polyions. We focus here on the Coulombic contribution to the…
Renormalized charge in a two-dimensional model of colloidal suspension from hypernetted chain approach
Manuel Camargo, Gabriel Tellez
The renormalized charge of a simple two-dimensional model of colloidal suspension was determined by solving the hypernetted chain approximation and Ornstein-Zernike equations. At t…
Exact asymptotic expansions for the cylindrical Poisson-Boltzmann equation
G. Tellez, E. Trizac
The mathematical theory of integrable Painleve/Toda type systems sheds new light on the behavior of solutions to the Poisson-Boltzmann equation for the potential due to a long rod-…
Finite-Thickness and Charge Relaxation in Double-Layer Interactions
Aldemar Torres, Rene van Roij, Gabriel Tellez
We extend the classical Gouy-Chapman model of two planar parallel interacting double-layers, which is used as a first approximation to describe the force between colloidal particle…
Onsager-Manning-Oosawa condensation phenomenon and the effect of salt
Emmanuel Trizac, Gabriel Tellez
Making use of results pertaining to Painleve III type equations, we revisit the celebrated Onsager-Manning-Oosawa condensation phenomenon for charged stiff linear polymers, in the…
