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 ...

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 ...

Chemists and physicists shed light on a crucial aspect of friction: how things begin to slide. Using fluorescence microscopy and dedicated fluorescent molecules, they are able to pinpoint how and when ...

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 ...

For machines with mechanical elements, friction is an unavoidable enemy. It is a major source of service failure and can reduce the lifespan of any machinery, from bicycles and cars to airplanes and ...

For the first time, ETH Zurich Materials Scientists have measured the rolling friction of microscopic, micrometer-sized particles. These measures allow them to better understand common items like ...
