Scientists have explored friction at the microscopic level. They discovered that the force generating friction is much stronger than previously thought. The discovery is an important step toward ...

Step inside the strange world of a superfluid, a liquid that can flow endlessly without friction, defying the common-sense rules we experience every day, where water pours, syrup sticks and coffee ...

A microscopic model describing frictional forces between a tip and a surface near its melting point predicts different behaviour for grazing friction compared with ploughing friction On a macroscopic ...

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 ...

The friction between a silicon ball and silicon wafer was measured in the experimental set-up shown on the left. The new research demonstrates that there is a direct relation between two effects: the ...

Nanomachines will depend on our knowledge of friction, heat transfer and energy dissipation at the atomic level for their very survival. In the scramble to revolutionize the world with nanotechnology ...

On a macroscopic scale, the physics of friction is well understood: skiers do their utmost to minimize it whereas racecar drivers hang on to it desperately during high-speed cornering. Yet, the ...

Nanoscale knowledge of the relationships between water, friction and mineral chemistry could lead to a better understanding of earthquake dynamics, researchers said in a new study. Engineers used ...

At a busy street crossing, people wait for the signal to change. When one person steps out first, others soon follow. Scientists in Amsterdam have found that this same kind of behavior happens at a ...

Friction has been an ever-lasting research problem, ever since the fundamental experimental observations of Leonardo Da Vinci, through the empirical laws postulated by Amontons and Couloumb and until ...
