Ultrasoft primitive model of polyionic solutions: structure, aggregation, and dynamics
Daniele Coslovich, Jean-Pierre Hansen, Gerhard Kahl
We introduce an ultrasoft core model of interpenetrating polycations and polyanions with continuous Gaussian charge distributions, to investigate polyelectrolyte aggregation in dil…
Identification of rolling resistance as a shape parameter in sheared granular media
Nicolas Estrada, Émilien Azema, Farhang Radjaï +1
Using contact dynamics simulations, we compare the effect of rolling resistance at the contacts in granular systems composed of disks with the effect of angularity in granular syst…
Superstructures par agrégation contrôlée de nanocolloïdes: caractérisation structurale par diffusion de neutrons aux petits angles et simulation numérique
Jean-Francois Berret, Julian Oberdisse
The complexation of micelles or charged nanoparticles with neutral-charged block copolymers in aqueous solutions leads to the formation of colloidal superstructures also termed 'co…
Une brève introduction à la matière molle
Fabrice Cousin, Isabelle Grillo, Jacques Jestin +1
A short introduction to soft condensed matter (polymers, colloids, surfactants) is presented, with particular emphasis to recent progres and applications of small angle scattering.…
Clustering, conductor-insulator transition and phase separation of an ultrasoft model of electrolytes
Daniele Coslovich, Jean-Pierre Hansen, Gerhard Kahl
We investigate the clustering and phase separation of a model of ultrasoft, oppositely charged macroions by a combination of Monte Carlo and Molecular Dynamics simulations. Static…
