Living bacteria embedded in silicone can absorb green LED light and re-emit it as red, offering a potential sustainable ...

(Nanowerk News) Researchers at the University of Ottawa have made a discovery that changes what we know about light and materials. They found that engineered achiral (symmetric) materials, called ...

Wildfire smoke is no longer just a short‑lived air quality problem drifting over cities for a few hazy days. New research shows that when these plumes rise high into the atmosphere, they can spawn ...

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 ...

For a long time, it was thought that amorphous solids do not selectively absorb light because of their disordered atomic structure. A new study disproves this theory and shows that amorphous solids ...

Researchers at the University of Ottawa have found that engineered achiral (symmetric) materials, called achiral plasmonic metasurfaces, can absorb light differently depending on the handedness of the ...

Figure 1: An atomically thin flake of tungsten diselenide acts as a reservoir for excitons, which are made up of electrons (red) and holes (blue). These excitons ...

Bobbing along on the research vessel Western Flyer just outside California’s Monterey Bay, marine biologist Karen Osborn and her colleagues were hauling deep-sea fish to the surface for cataloging and ...

In a development that could lead to cheaper lasers, researchers have discovered that perovskite solar cells can emit as well as absorb light. By sandwiching a thin layer of lead halide perovskite ...

Some of the bacteria that live in ponds grow faster during the day, even if they don't take in sunlight as an energy source, suggesting the existence of special genes that absorb light. Some of the ...

Colour is all around us, but almost all pure compounds are white. That's not surprising when you know what it takes to make a thing coloured, writes Theodore Gray. Only a few natural substances have ...
