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 ...

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 ...

For nearly two centuries, textbooks blamed icy spills on pressure and friction, but new simulations tell another story. The ...

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 ...

Friction is responsible for about twenty percent of the world energy consumption. The main reason for this is that frictional forces slow down the motion of surfaces in contact: think of the moving ...

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 ...

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 ...
