Inactive and abandoned oil and gas wells in Canada are a much bigger climate problem than previously thought, emitting seven ...

Emissions of hydrogen sulfide raise health concerns in communities near California's largest lake, researchers say.

A study measured methane flow from more than 450 nonproducing wells across Canada, but thousands more remain unevaluated.

Virtually all light-emitting diodes used today require phosphors based on so-called rare-earth elements, which are expensive ...

The beleaguered California lake is running low and might be poisoning nearby communities with toxic hydrogen sulfide gas.

New research has found that the shrinking lake is emitting the foul-smelling gas hydrogen sulfide more frequently and at higher levels than previously measured.

Colloidal halide perovskite nanocrystals have emerged as strong candidates for light-emitting diodes and solar applications ...

Quantum dots with precise crystal growth and advanced processing enable compact, energy-efficient, and cost-effective light ...

In addition, we also present an overview of key areas of future research that have the potential to enable the next generation of UV-emitting devices. The electromagnetic spectrum is divided into ...

An international team reported Wednesday that this celestial object — perhaps a star, pair of stars or something else entirely — is emitting X-rays around the same time it's shooting out radio ...
