Charge neutrality breakdown in confined aqueous electrolytes : theory and simulation
(2016) [Artigo de periódico]We study, using Density Functional theory (DFT) and Monte Carlo simulations, aqueous electrolyte solutions between charged infinite planar surfaces, in contact with a bulk salt reservoir. In agreement with recent experimental ... -
Equation of state of charged colloidal suspensions and its dependence on the thermodynamic route
(2012) [Artigo de periódico]The thermodynamic properties of highly charged colloidal suspensions in contact with a salt reservoir are investigated in the framework of the renormalized Jellium model (RJM). It is found that the equation of state is ... -
Equilibrium properties of charged microgels : a Poisson-Boltzmann-Flory approach
(2014) [Artigo de periódico]The equilibrium properties of ionic microgels are investigated using a combination of the Poisson-Boltzmann and Flory theories. Swelling behavior, density profiles, and effective charges are all calculated in a self-consistent ... -
Ionic size effects on the Poisson-Boltzmann theory
(2017) [Artigo de periódico]In this paper, we develop a simple theory to study the effects of ionic size on ionic distributions around a charged spherical particle. We include a correction to the regular Poisson-Boltzmann equation in order to take ... -
A self-consistent renormalized jellium approach for calculating structural and thermodynamic properties of charge stabilized colloidal suspensions
(2009) [Artigo de periódico]An approach is proposed which allows to self-consistently calculate the structural and the thermodynamic properties of highly charged aqueous colloidal suspensions. The method is based on the renormalized jellium model ... -
Structural anomalies for a three dimensional isotropic core-softned potential
(2006) [Artigo de periódico]Using molecular dynamics simulations we investigate the structure of a system of particles interacting through a continuous core-softened interparticle potential. We found for the translational order parameter t a local ... -
The renormalized Jellium model of colloidal suspensions with multivalent counterions
(2010) [Artigo de periódico]An extension of the renormalized Jellium model which allows to study colloidal suspensions containing trivalent counterions is proposed. The theory is based on a modified Poisson–Boltzmann equation which incorporates the ... -
Thermodynamic and dynamic anomalies for a three-dimensional isotropic core-softened potential
(2006) [Artigo de periódico]Using molecular-dynamics simulations and integral equations (Rogers-Young, Percus-Yevick, and hypernetted chain closures) we investigate the thermodynamics of particles interacting with continuous core-softened intermolecular ... -
Yukawa particles in a confining potential
(2014) [Artigo de periódico]We study the density distribution of repulsive Yukawa particles confined by an external potential. In the weak coupling limit, we show that the mean-field theory is able to accurately account for the particle distribution. ...
