Torrent frog has advantage attaching to rough, wet surfaces

Torrent frogs use their toes, belly, and thighs to attach to rough, wet, and steep surfaces, according to results published September 25 in the open access journal PLOS ONE by Thomas Endlein from the Centre for Cell Engineering ...

Researchers create solar cells with record energy performance

Researchers at the Department of Electronic Engineering of the Universitat Politècnica de Catalunya (UPC) have obtained a record efficiency of 22% with silicon solar cells that incorporate a surface treatment called black ...

Researchers identify cause of LED 'efficiency droop'

(Phys.org) —Rensselaer Polytechnic Institute researchers have identified the mechanism behind a plague of LED light bulbs: a flaw called "efficiency droop" that causes LEDs to lose up to 20 percent of their efficiency as ...

Bubbles are the new lenses for nanoscale light beams

Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for next-generation, ...

Study reveals origin of superconductivity in nickelates

Nickelates are a material class that has excited scientists because of its recently discovered superconducting ability, and now a new study led by Cornell has changed where scientists thought this ability might originate, ...
