Everybody knows that sliding on ice or snow, is much easier than sliding on most other surfaces. But why is the ice surface slippery? Researchers have now shown that the slipperiness of ice is a ...

For more than 200 years, scientists have argued about a deceptively simple question: why does a sheet of frozen water let us glide, skid and fall so easily. Now a new generation of simulations and ...

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 ...

(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 ...

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 ...

1.1 What is friction? Take this everyday example: when a coffee mug rests on a flat table, the kinetic frictional force is zero. There is no force trying to move the mug across the table, so there is ...

The study of tribology, the science of friction, wear and lubrication, has increasingly benefitted from advances in molecular dynamics simulations, providing detailed atomistic insights into the ...

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 ...

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 streams have ...
