Electric Fields Near Undulating Dielectric Membranes
Nicholas Pogharian, Alexandre P. dos Santos, Ali Ehlen +1
Dielectric interfaces are crucial to the behavior of charged membranes, from graphene to synthetic and biological lipid bilayers. Understanding electrolyte behavior near these inte…
Modulation of ionic conduction using polarizable surfaces
Alexandre Pereira dos Santos, Felipe Jiménez-Ángeles, Ali Ehlen +1
Hybrid ionic-electronic conductors have the potential to generate memory effects and neuronal behavior. The functionality of these mixed materials depends on ion motion through thi…
Mean-field beyond mean-field: the single particle view for moderately to strongly coupled charged fluids
L. Samaj, A. P. dos Santos, Y. Levin +1
In a counter-ion only charged fluid, Coulomb coupling is quantified by a single dimensionless parameter. Yet, the theoretical treatment of moderately to strongly coupled charged fl…
Charge neutrality breakdown in confined aqueous electrolytes: theory and simulation
Thiago Colla, Matheus Girotto, Alexandre P. dos Santos +1
We study, using Density Functional theory and Monte Carlo simulations, aqueous electrolyte solutions between charged infinite planar surfaces, in a contact with a bulk salt reservo…
Interaction between random heterogeneously charged surfaces in an electrolyte solution
Amin Bakhshandeh, Alexandre P. dos Santos, Alexandre Diehl +1
We study, using Monte Carlo simulations, the interaction between infinite heterogeneously charged surfaces inside an electrolyte solution. The surfaces are overall neutral with que…
Electrolytes between dielectric charged surfaces: Simulations and theory
Alexandre P. dos Santos, Yan Levin
We present a simulation method to study electrolyte solutions in a dielectric slab geometry using a modified 3D Ewald summation. The method is fast and easy to implement, allowing…
Adsorption of cationic polyions to a hydrophobic surface in the presence of Hofmeister salts
Alexandre P. dos Santos, Yan Levin
We study, using extensive Monte Carlos simulations, the behavior of cationic polyelectrolytes near hydrophobic surfaces in solutions containing Hofmeister salts. The Hofmeister ani…
Equation of state of charged colloidal suspensions and its dependence on the thermodynamic route
Thiago E. Colla, Alexandre P. dos Santos, Yan Levin
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…
Weak and Strong Coupling Theories for Polarizable Colloids and Nano-Particles
Amin Bakhshandeh, Alexandre Pereira dos Santos, Yan Levin
A theory is presented which allows us to accurately calculate the density profile of monovalent and multivalent counterions in suspensions of polarizable colloids or nano-particles…
Surface tensions, surface potentials and the Hofmeister series of electrolyte solutions
Alexandre P. dos Santos, Alexandre Diehl, Yan Levin
A theory is presented which allows us to accurately calculate the surface tensions and the surface potentials of electrolyte solutions. Both the ionic hydration and the polarizabil…
Ions at the air-water interface: An end to one hundred year old mystery?
Yan Levin, Alexandre P. dos Santos, Alexandre Diehl
Availability of highly reactive halogen ions at the surface of aerosols has tremendous implications for the atmospheric chemistry. Yet neither simulations, experiments, nor existin…
