(Nanowerk News) Researchers at UCL in a collaboration study with Laurent Joly, from the University of Lyon, have investigated the friction properties of liquid water at the interface with graphene and ...

Protein dynamics are essential for their functions. Protein nanomachines made of multiple protein molecules are highly dynamics during their actions on their functional targets, sometime called ...

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 ...

In November 2008, the space shuttle Endeavor visited the International Space Station to do some important repair work. A critical part of the mission was to service the station’s two rotary joints, ...

• Excessive seal friction wastes energy, accelerates wear, and can lead to premature failure. • Too little friction makes a seal prone to leak. • Pressure-activated hydraulic seals minimize both ...
