Physicists have developed an experimental technique to simulate friction at the nanoscale. Using their technique, the researchers are able to directly observe individual atoms at the interface of two surfaces and manipulate their arrangement, tuning the amount of friction between the surfaces. By changing the spacing of atoms on one surface, they observed a point at which friction disappears.
Inspired by octopuses and chameleons, researchers have developed technique for using a metallic nanostructure to create the first full-color, flexible display so thin it could be used to create color-changing clothing.
Physicists have developed a new ultrafast light source for observing electron motion in molecules -- made up of nuclei and electrons -- at the point before the nuclei start to move. By being able to observe what actually happens, sc...
Physicists have built a microscope that is able to see up to 1,000 individual fermionic atoms. The researchers devised a laser-based technique to trap and freeze fermions in place, and image the particles simultaneously.
New experiments have uncovered a way of controlling friction on ionic surfaces at the nanoscale using electrical stimulation and ambient water vapor.
