Controlling friction by tuning van der Waals forces

Posted: 19 Jul 2013 05:39 AM PDT

For a car to accelerate there has to be friction between the tire and the surface of the road. The amount of friction generated depends on numerous factors, including the minute intermolecular forces acting between the two surfaces in contact – so-called van der Waals forces. The importance of these intermolecular interactions in generating friction has long been known, but has now been demonstrated experimentally for the first time.
