(Phys.org)—A small team of researchers at IBM Research–Zürich, has found a new way to measure the friction involved when two planes of highly ordered pyrolytic graphite (HOPG) are moved against one another. In their ...
Technological limitations have made studying friction on the atomic scale difficult, but researchers at the University of Pennsylvania and the University of California, Merced, have now made advances in that quest on two ...

(Phys.org)—When nanosized pieces of graphite slide against each other, there can be virtually no friction between them. For many years, superlow friction, or "superlubricity," was known to exist only on the nanoscale. Then ...
Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at the Department of Energy's Oak Ridge National ...
