Transparent window coatings that keep buildings and cars cool on sunny days. Devices that could more than triple solar cell efficiencies. Thin, lightweight shields that block thermal detection. These ...
Recently, researchers have looked beyond traditional semiconductor materials to create devices using a promising class of ...
Researchers have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called achiral plasmonic metasurfaces, can absorb light ...
About 2.5 billion years ago, a pigment called chlorophyll appeared in single-celled organisms, allowing them to capture energy in the form of light and convert it into sugars. This biochemical trick, ...
Imagine a car so black it behaves like a sort of black hole on wheels. Instead of bouncing back sunlight toward your eyes, almost every ray is swallowed, giving the vehicle an unusually flat and ...
A group of physicists from Russia, Sweden, and the U.S. has demonstrated a highly unusual optical effect: They managed to "virtually" absorb light using a material that has no light-absorbing capacity ...
