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 ...

But scientists have struggled for decades to accurately calculate the value of friction, which is part of the data used when running coarse-grained simulations, Guenza said. As molecules move through ...

RALEIGH, N.C. — North Carolina State University professor Jan Genzer has hit on a method for creating the ultimate nonstick surface. Potential applications include covering adjacent disk-drive ...

A custom line of low-friction compounds for single and dual-layer tube extrusion, injection molding, and blow molding applications has been introduced by Peak Performance Compounding. Described as a ...

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 ...

In a Columbia University laboratory in New York, physicist Sebastian Will and his team have reached one of ultracold physics’ ...

For nearly two centuries, textbooks blamed icy spills on pressure and friction, but new simulations tell another story. The team shows that ice can remain slippery near minus 40 degrees Fahrenheit ...

Computer simulations help materials scientists and biochemists study the motion of macromolecules, advancing the development of new drugs and sustainable materials. However, these simulations pose a ...

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 ...
