Friction exists because most surfaces really look like this under a microscope. Note the hills, the crests and the valleys. These are called asperities, or material deformations. They occur on rough ...

Water flows more easily through narrower carbon nanotubes than larger ones and we have struggled to explain why. Now, one team has an answer: it may all be due to quantum friction. Friction in its ...
