Their research on "bismuth islands" moving on the surface of graphite confirmed the existence of a totally new form of ...

The amount of friction depends on the fluid viscosity and the velocity gradient (that is, the relative velocity between fluid layers). The velocity gradients are set up by the no-slip condition at the ...

If you take two objects with fairly smooth surfaces, and put these together, you would not expect them to stick together. At ...

Picture yourself at a busy pedestrian crossing. When the light is red, everyone waits -- until one person starts to cross. Soon, others follow, and eventually everyone follows the crowd and crosses.

Research conducted at CSET encompasses areas such as fundamental theories of friction,adhesion, wear, contact, and lubrication, lubricant and tribochemistry development, contact fatigue testing and ...

Now we call these contact forces ... Friction is a force that is created when one surface slides over another. Friction works in the opposite direction to the direction of the moving object.

The reasons for this 'renaissance of friction' are the development of highly sensitive experimental tools, such as friction force microscopes, surface ... of individual contacts and macroscopic ...

All you need is a rotary tool. “Friction welding” is the process of rubbing two surfaces together until the friction alone has created enough heat to join them. Industrially, the method is ...

Does it get harder to slide the two surfaces along ... that the amount of friction depends on a very interesting underlying process. At low applied force, only one tiny contact point—a so ...
