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 ...

(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 ...

Interactions between molecules and electrons in carbon nanotube walls can cause 'quantum friction'. (Courtesy: Geoffrey Monet, ENS) When water moves through nano-sized channels made of carbon, its ...

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 ...

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 ...

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 ...
