Everybody knows how friction works, right? Rub two things against each other, and they stick together a little, depending on the material. It's why you don't slip around on the sidewalk, unless it's ...

MIT scientists have coaxed atoms into an exotic “edge state” for the first time, allowing them to flow completely friction-free. The breakthrough could lead to better superconductor materials. As ...

If you want to reduce the friction between tiny objects, just increase the mass of the atoms at one surface, say researchers in the US. Heavier atoms vibrate at lower frequencies than their lighter ...

PHILADELPHIA –- A research team led by a University of Pennsylvania mechanical engineer has discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by ...

Researchers at TU Wien have discovered a quantum system where energy and mass move with perfect efficiency. In an ultracold ...

The familiar heat, wear and general grinding to a halt of friction are all caused by what's going on at the microscopic level when two things rub. And down there, even the smoothest surfaces usually ...

Using advanced microscopic techniques, researchers from labs around the world have shed light on the molecular basis of friction. Friction is a force that opposes motion when two materials slide over ...

PROVIDENCE, R.I. -- Dump baking soda into a glass of vinegar and a chemical reaction occurs. Molecules start a chaotic dance, bouncing and bumping into each other. Friction, which primes molecules for ...

It’s a moonless night. The wind howls outside. A door opens slowly, as if pushed by an invisible hand. “Cre-e-e-a-k.” That sound — a horror movie cliché — is the result of friction. A stealthier ...

Mechanical engineers have discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by changing the mass of the atoms at the surface. 'Heavier' atoms ...

(Nanowerk News) A research team led by a University of Pennsylvania mechanical engineer has discovered that friction between two sliding bodies can be reduced at the molecular, or nanoscale, level by ...
