Schematic illustration of Friction Force Microscopy (FFM). The AFM cantilever, a small diving board-like structure about 200 micrometers long, 50 micrometers wide, and 1 micrometer thick, has a sharp ...

Experiments suggest that hydrogen bonding explains why a wet surface can have nearly twice as much friction as a dry surface. Record bonding. Experiments have probed the friction between a silicon ...

Scientists have made an insight into superlubricity, where surfaces experience extremely low levels of friction. This could benefit future technologies by reducing energy lost to friction by moving ...
