Friction is a force resisting relative motion and it occurs at the interface between the bodies, but also within the bodies, like in case of fluids. The concept of friction coefficient was first formulated by […]

Tribology to analyze wine mouthfeel

13.12.2018

Researchers at the University of California, Davis, are investigating whether an analytical technique to measure friction between two surfaces can provide better understanding of wine sensory perception related to astringency and mouthfeel. Mouthfeel is an [...]
Ice crystals formation is controlled by the surface texture - new study shows

18.05.2017

WASHINGTON (May 17, 2017)—A new study examining how ice forms from pure water found that the geometry of the surface that water is on can have an effect on whether or not it freezes, suggesting [...]
Atomic scale deformation responsible for surface roughness

04.05.2020

Most of the natural or engineered surfaces are not perfect, meaning they are rough. The surface roughness was found across many scales: from atomic to tectonic. The earth looks smooth from space, but someone standing [...]
Metallic Glass Gears for NASA Robots

07.08.2017

Throw a baseball, and you might say it’s all in the wrist. For robots, it’s all in the gears. Gears are essential for precision robotics. They allow limbs to turn smoothly and stop on command; [...]
Origins of Sliding Friction

08.06.2020

Origin of sliding friction: role of lattice trapping The friction force acting on a block sliding on a substrate is usually nearly velocity independent unless the sliding speed is so low that thermal activation is [...]
