Friction usually announces itself through contact. A chair scraping across a floor, a tire gripping asphalt, a hand sliding ...

A new analysis of the 2018 collapse of Kilauea volcano's caldera helps to confirm the reigning scientific paradigm for how friction works on earthquake faults. The model quantifies the conditions ...

(Nanowerk News) 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 ...

On April 30, 2018, on the eastern flank of Hawaii’s Kīlauea volcano, lava suddenly drained from a crater that had been spewing lava for more than three decades. Then the floor of the crater, named ...

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 ...

Memory fault: friction study could provide new insights into why earthquakes happen. (Courtesy: iStock/allanswort) Experiments by Sam Dillavou and Shmuel Rubinstein at Harvard University have, for the ...

Whenever you get around to doing dishes, how easily water slides down a dirty plate depends on how uneven and crusty the plate’s surface is. At the nanoscale, however, where surface features can be ...

Winter sports such as skiing, speed skating, figure skating, and curling require the slippery surfaces of ice and snow. While the fact that the ice surface is slippery is widely acknowledged, it is ...
