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 ...

Through a multi-university collaboration, researchers at Virginia Tech have discovered a new, solid lubricating mechanism that can reduce friction in machinery at extremely high temperatures. It works ...

Solid lubricants can be utilized as free-flowing powders, as additives in some oils and greases, and as key ingredients in high-performance anti-friction coatings and anti-seize pastes. These special ...

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 ...

Low-friction coatings are used on bearings for two reasons. The first is as a backup lubricant if the primary (fluid) lubricant fails or is insufficient to prevent surface-to-surface contact.

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 ...

OAK RIDGE, Tenn. Jan 27, 2015 - Friction impacts motion, hence the need to control friction forces. Currently, this is accomplished by mechanistic means or lubrication, but experiments conducted by ...
