The friction between a silicon ball and silicon wafer was measured in the experimental set-up shown on the left. The new research demonstrates that there is a direct relation between two effects: the ...

Managing friction at the wheel-rail interface is one of the top priorities for railway operators. An effective friction management system can reduce noise and vibration while simaltaneously improving ...

Electrically tunable ionic hydrogels use small voltages to switch friction at metal contacts between high-friction and ultra-low-friction states, enabling voltage-programmed grip, release and motion ...
