New type of friction discovered in ligand-protein systems

An interdisciplinary research team of the Institutes of Physical Chemistry and Physics of the University of Freiburg and the Max Planck Institute of Biophysics in Frankfurt-am-Main has discovered a new, direction-dependent ...

At the nanoscale, graphite can turn friction upside down

(Phys.org)—If you ease up on a pencil, does it slide more easily? Sure. But maybe not if the tip is sharpened down to nanoscale dimensions. A team of researchers at the National Institute of Standards and Technology (NIST) ...

How to control friction in topological insulators

Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating ...

The limits of friction

Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic processes. However, to ...

Study of friction reveals clues about arthritis

(Phys.org)—A new, noninvasive, and low-cost method for the early detection and monitoring of osteoarthritis (arthritis caused by wear and tear) may be on its way, thanks to research by UC Santa Barbara scientists from the ...

Unexpected speed-dependent friction in graphene

Due to their low-friction properties, materials consisting of single atomic layers are of great interest for applications where the aim is to reduce friction—such as hard disks or moving components for satellites or space ...
