Modeling structures that trap air under water and could one day lead to more energy-efficient ships described in the journal 'Physics of Fluids' From the sleek hulls of racing yachts to Michael Phelps' shaved legs, most objects that move through the water quickly are also smooth. But researchers from UCLA have found that bumpiness can sometimes be better. "A properly designed rough surface, contrary to our intuition, can reduce skin-friction drag," said John Kim, a professor in the...

Researchers Observe High Energy Losses In Vicinity Of Charge Density Waves
2013-12-16 07:29:11

University of Basel In collaboration with the University of Basel, an international team of researchers has observed a strong energy loss caused by frictional effects in the vicinity of charge density waves. This may have practical significance in the control of nanoscale friction. The results have been published in the scientific journal Nature Materials. Friction is often seen as an adverse phenomenon that leads to wear and causes energy loss. Conversely, however, too little friction...

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 by a research team led by Physics...

Physicists Discover New Kind Of Friction

Technische Universitaet Muenchen Whether in vehicle transmissions, hip replacements, or tiny sensors for triggering airbags: The respective components must slide against each other with minimum friction to prevent loss of energy and material wear. Investigating the friction behavior of nanosystems, scientists from the Technische Universitaet Muenchen (TUM) have discovered a previously unknown type of friction that sheds new light on some previously unexplainable phenomena. Friction is...
