(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 ...

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

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 ...

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 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 ...

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 ...

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 ...

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 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 ...

Finding the right lubricant for the right purpose is a task that is often extremely important in industry. Not only to reduce friction, overheating and wear, but also to save energy. At TU Wien, the ...
