Superlubricity graphite research from Tsinghua University has overturned a 30-year rule: a perfectly ordered graphite ...

Friction is hard to predict and control, especially since surfaces that come in contact are rarely perfectly flat. New experiments demonstrate that the amount of friction between two silicon surfaces, ...

Conservation laws are central to our understanding of the universe, and now scientists have expanded our understanding of these laws in quantum mechanics. A conservation law in physics describes the ...

An interdisciplinary research team of the Institutes of Physical Chemistry and Physics of the University of Freiburg and the Max Planck Institute of Biophysics in Frankfurt-am-Main has discovered a ...

A new experimental method based on atomic force microscopy allows the investigation of friction at the scale of individual atoms. A directional dependence of friction, also known as friction ...

A suspended apparatus used to minimize friction during the experiment. The heavier brass cylinder and lighter ping-pong ball collide repeatedly against the transparent wall, reproducing 31 collisions ...

Experiments suggest that hydrogen bonding explains why a wet surface can have nearly twice as much friction as a dry surface. Record bonding. Experiments have probed the friction between a silicon ...

The measuring tip of an atomic force microscope with a specially designed holder in which a spherical particle is “trapped”. The rights to the images always remain with the person referred to as the ...
