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 ...

(Nanowerk News) For 15 years, scientists have been baffled by the mysterious way water flows through the tiny passages of carbon nanotubes — pipes with walls that can be just one atom thick. The ...

Scientists have now uncovered new velocity and temperature-dependent properties of rubber friction on asphalt -- bolstering the idea that an important component of friction originates when chains of ...

Chemists and physicists at the University of Amsterdam shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they ...

Physicists have developed an experimental technique to simulate friction at the nanoscale. Using their technique, the researchers are able to directly observe individual atoms at the interface of two ...

The Saarland researchers reveal that the slipperiness of ice is driven by electrostatic forces, not melting. Water molecules in ice are arranged in a rigid crystal lattice. Each molecule has a ...

The concepts of friction and wear are easy to understand, yet they can interrelate in complex ways within a tribological system (science concerned with interacting surfaces in relative motion ...
