Proceedings of the Workshop on Force Fields: From atoms to materials, which was held from November 3-5, 2014, at Forschungszentrum Jülich are now published at

Lubrication of biological systems often involves the presence of polymers that are end-anchored to rubbing surfaces. The polymers swell in a solvent to form brushes, which then act as low-viscosity bearings when surfaces slide against a counter face.
In a recent article, featured on the cover of Soft Matter and picked as one of July’s hot papers by RSC, we investigated a commonly assumed hypothesis: Friction between rubbing surfaces is predominantly induced by the mutual penetration of opposing polymer brushes. (more…)
