The dynamics of how liquids behave when confined in a nanoscale-sized space such as nanochannels, nanotubes or nanopores, is key to understanding a wealth of processes including lubrication, ...

Finding the right lubricant for the right purpose is a task that is often extremely important in industry. Not only to reduce friction, overheating and wear, but also to save energy. At TU Wien, the ...

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 ...
