Soft effective interactions between weakly charged polyelectrolyte chains
Martin Konieczny, Christos N. Likos, Hartmut Löwen
We apply extensive Molecular Dynamics simulations and analytical considerations in order to study the conformations and the effective interactions between weakly charged, flexible…
Homogeneous nucleation of colloidal melts under the influence of shearing fields
Ronald Blaak, Stefan Auer, Daan Frenkel +1
We study the effect of shear flow on homogeneous crystal nucleation, using Brownian Dynamics simulations in combination with an umbrella sampling like technique. The symmetry break…
Crystal Nucleation of Colloidal Suspensions under Shear
Ronald Blaak, Stefan Auer, Daan Frenkel +1
We use Brownian Dynamics simulations in combination with the umbrella sampling technique to study the effect of shear flow on homogeneous crystal nucleation. We find that a homogen…
Effect of Image Forces on Polyelectrolyte Adsorption at a Charged Surface
Rene Messina
The adsorption of flexible and highly charged polyelectrolytes onto oppositely charged planar surfaces is investigated by means of Monte Carlo simulations. The effect of image forc…
Contact Angle of the Colloidal Liquid-Gas Interface and a Hard Wall
Paul P. F. Wessels, Matthias Schmidt, Hartmut Lowen
We consider the Asakura-Oosawa-Vrij model of hard sphere colloids and ideal polymer coils in contact with a planar hard wall at (colloidal) liquid-gas coexistence. Using extensive…
DNA-condensation, redissolution and mesocrystals induced by tetravalent counterions
E. Allahyarov, H. Löwen, G. Gompper
The distance-resolved effective interaction potential between two parallel DNA molecules is calculated by computer simulations with explicit tetravalent counterions and monovalent…
