Nanofriction on the tip of the microscope
Rome, Italy (SPX) Dec 20, 2013
Atomic force microscopes are able to reproduce spectacular images, at the scale of single atoms. This is made possible by the oscillation of a very sharp probe tip over the surface being observed. The tip never touches the surface but gets so close to it, at distances in the order of one billionth of a metre, that it "feels" the force due to the interaction with the atoms making up the material being observed. These are tiny forces, in the order of nanonewtons (meaning one billion times smaller th ... read more
