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 ...

The speed of water flow is a limiting factor in many membrane-based industrial processes, including desalination, molecular separation and osmotic power generation. Researchers have revealed a ...

The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers. The friction on a graphene surface can be dynamically tuned using external ...

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 ...

The question is not how to eliminate friction. The question is how to manage it so it becomes traction and traction becomes forward motion.

The speed of water flow is a limiting factor in many membrane-based industrial processes, including desalination, molecular separation and osmotic power generation. Researchers at The University of ...

(Nanowerk News) The friction on a graphene surface can be dynamically tuned using external electric fields, according to researchers at the University of Illinois Urbana-Champaign led by Professor ...
