Papers
A self-consistent mean-field model for polyelectrolyte gels
Oleg Rud,Oleg Rud,Tobias Richter,Oleg V. Borisov,Oleg V. Borisov,Christian Holm,Peter Košovan +6 more
TL;DR: It is demonstrated that the local density gradients are important and that the ionization of the weak polyelectrolyte gel is significantly suppressed, under the studied conditions the effective pKA is about one unit higher than that of the free monomer.
Overcharging: The crucial role of excluded volume
René Messina,Enrique González-Tovar,Enrique González-Tovar,Enrique González-Tovar,Marcelo Lozada-Cassou,Marcelo Lozada-Cassou,Christian Holm +6 more
TL;DR: In this paper, the authors investigated the mechanism for the overcharging of a single spherical colloid in the presence of aqueous salts within the framework of the primitive model by molecular dynamics (MD) simulations as well as integral-equation theory.
Modeling multibody effects in ionic solutions with a concentration dependent dielectric permittivity
TL;DR: A new strategy to parametrize effective ion-ion potentials for implicit solvent simulations of charged systems by means of a concentration dependent dielectric permittivity takes into account multibody effects is reported.
Ground state structures in ferrofluid monolayers
TL;DR: In this paper, a combination of analytical calculations and Monte Carlo simulations is used to find the ground state structures in monodisperse ferrofluid monolayers, and the most energetically favored structures are rings, embedded rings, and rings side by side.
Polyelectrolyte multilayering on a charged sphere
TL;DR: In this article, the adsorption of highly oppositely charged flexible polyelectrolytes on a charged sphere is investigated by means of Monte Carlo simulations in a fashion which resembles the layer-by-layer deposition technique introduced by Decher.
