A suspended apparatus used to minimize friction during the experiment. The heavier brass cylinder and lighter ping-pong ball collide repeatedly against the transparent wall, reproducing 31 collisions ...

Whenever you get around to doing dishes, how easily water slides down a dirty plate depends on how uneven and crusty the plate’s surface is. At the nanoscale, however, where surface features can be ...

The best part about living in Vermont is that we get to experience all of the seasons. Sometimes cool weather appears out of nowhere and we don’t have the proper attire so we rub our hands together to ...

Nanotribology is the study of friction, wear, and lubrication at the nanoscale. It focuses on understanding and controlling the interactions between surfaces in relative motion when the contact area ...

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 ...

Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists have begun investigating how they react to friction. Their ...
