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 ...

(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 ...

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 ...

You know that two surfaces mate, but what is a friction clutch or brake? Using friction has been the most popular way to engage and stop loads since the 1800s. Surfaces interact with ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...
