Counterion density profiles at charged flexible membranes.
نویسندگان
چکیده
Counterion distributions at charged flexible membranes are studied using analytical and simulation methods in both Poisson-Boltzmann and strong-coupling limits. The softer the membrane, the more smeared out the counterion-density profile becomes and counterions penetrate through the mean-membrane surface location, in agreement with anomalous scattering results. Repulsion between membrane charges enhances protrusions and induces short-scale membrane roughening.

Modes of counterion density fluctuations and counterion-mediated attractions between like-charged fluid membranes.
Counterion-mediated attractions between like-charged fluid membranes are long ranged and nonpairwise additive at high temperatures. At low temperatures, however, they are pairwise additive, and decay exponentially with the membrane separation. Using a simple model for the electrostatic attraction between like-charged surfaces, we show that the nature of these attractions is determined by the do...
متن کاملElasticity and mechanical instability of charged lipid bilayers in ionic solutions.
We use coarse-grained Monte Carlo simulations to study the elastic properties of charged membranes in solutions of monovalent and pentavalent counterions. The simulation results of the two cases reveal trends opposite to each other. The bending rigidity and projected area increase with the membrane charge density for monovalent counterions, while they decrease for the pentavalent ions. These ob...
متن کاملManning-Oosawa counterion condensation.
Counterion condensation is a basic feature of 2D electrostatics exhibited by highly charged rodlike polymers such as DNA. In the framework of the Poisson Boltzmann equation with salt, we show that such a polymer of radius a attracts a condensate of thickness RM=A(axi)1/2 where xi is the Debye length and A depends weakly on the polymer charge density q0. To leading order in 1/ln(xi/a), we derive...
متن کاملColloidal charge renormalization in suspensions containing multivalent electrolyte.
A theory is proposed which allows us to self-consistently calculate the effective colloidal charge and the counterion and coion density profiles in suspensions containing both multivalent and monovalent electrolytes. The formation of counterion-coion clusters is explicitly taken into account. The theory predicts that sufficiently strongly charged colloidal particles will become overcharged. The...
متن کاملEffects of pore size and surface charge on Na ion storage in carbon nanopores.
Na ion batteries (NIBs) are considered as a promising low cost and sustainable energy storage technology. To better design nanoporous carbons as anode materials for NIBs, molecular dynamics simulations have been employed to study the behavior of Na+ ions (as well as PF6- ions) confined within carbon nanopores, in the presence of non-aqueous (organic) solvent. The effects of pore size and surfac...
