But when Dogic’s team dragged two actin filaments against each other, they observed frictional forces nearly 1,000 times greater than expected — closer to the solid friction created by, say, pushing ...
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 ...

Ranch dressing is actually a fifth state of matter known as soft matter. Soft matter can have properties of both liquids and solids, so materials scientists say it is viscoelastic – a combination of ...
Probably the heat generated by the friction of the solid parts of the pump was also communicated to the water, and tended to elevate its temperature. Count Rumford, by boring a cylinder of cast ...
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.
Not only to reduce friction, overheating and wear ... The lubricant COK-47 is not liquid like lubricating oil, but a powdery solid substance. On a nanoscale, it consists of stacks of atomically ...
which ensures extremely low friction. This makes COK-47 a highly interesting lubricant in humid conditions. The findings have been published in Advanced Science ("Advanced Solid Lubrication with ...
