Team develops a flexible and stretchable device capable of omnidirectional color wavelength control. A team at Pohang University of Science and Technology (POSTECH), spearheaded by Professor Su Seok ...

a) Illustration of the omnidirectional wavelength-tunable color device featuring a mechanochromic chiral liquid crystal elastomer (CLCE) and an electrically deformable dielectric elastomer actuator ...

To overcome the lack of wavelength-selective extraction in existing on-chip metasurfaces, Chinese scientists developed a novel approach by leveraging a nonlocal on-chip design based on symmetry-broken ...

Physicists and vision scientists are lining up behind a provocative claim: the rich color we call purple is not a property of light at all, but a story the brain tells itself. Light in the real world ...

The color purple is, in a way, invented by our brains. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The world is awash with the color purple — ...

The technology, based on Fano resonance, results in a coating that fully reflects only a very narrow wavelength. The technology could improve the effectiveness of devices that use hybrid ...

Is purple a real color? Scientists think everything we've ever believed about the color purple may not be true due to the ...
