Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by researchers at the Department of ...

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, ...

WEST LAFAYETTE, Ind. – Researchers have created a new type of non-liquid lubricant that has been shown to reduce friction and wear significantly under the extreme conditions found in various ...

There is a very peculiar dynamics of granular matter, such as dry sand or grains of wheat. When these granular particles are left on a vibrating solid surface, they are not only subject to random ...

Friction is a key phenomenon in applied physics, whose origin has been studied for centuries. Until now, it has been understood that mechanical wear-resistance and fluid lubrication affect friction, ...

(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 ...

(Nanowerk News) 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.

It has been known for more than 200 years that the maximum static friction force between two solid surfaces is usually greater than the kinetic friction force—the force that is required to maintain ...

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 ...

The process by which sheared suspensions go through a dramatic change in viscosity is known as discontinuous shear thickening. Although well-characterized on the macroscale, the microscopic mechanisms ...
