Irregularities present on a surface are often described as surface roughness or texture. These surface textures such as grooves and dimples impart friction, which is the force between two sliding ...

Scientists led by the University of Leicester have made an insight into superlubricity, where surfaces experience extremely low levels of friction While many of us are treading carefully to avoid a ...

When you step onto an icy sidewalk or push off on skis, the surface can seem to vanish beneath you. For more than a century, ...

Surface roughness influences many mechanical properties, including friction and adhesion, surface reactivity, semiconductor substrate quality, and surface interaction with electromagnetic waves, ...

The lotus plant, otherwise known as the water lily, has been a source of inspiration for centuries. But this time, people are mostly interested in the bumps on the surface of its leaves. Researchers ...

Researchers have discovered for the first time, through theoretical calculation and experiment that macroscopic frictions occurring between clay mineral surfaces originate from interatomic ...

In November 2008, the space shuttle Endeavor visited the International Space Station to do some important repair work. A critical part of the mission was to service the station’s two rotary joints, ...

Michael Kanellos is editor at large at CNET News.com, where he covers hardware, research and development, start-ups and the tech industry overseas. Researchers at Ohio State University have created ...
