Researchers improve the stability of perovskite solar cells      (via sciencedaily.com)     Original source 

Perovskite solar cells are considered the strongest contender to replace silicon solar cells. While they achieve high power conversion energy, they also suffer from lead leakage and perovskite degradation due to moisture. Now scientists leverage the technique of interfacial passivation, where lead ions are bound by crown ether B18C6, obtaining 21.7% power conversion energy. The crown ether also resists degradation due to moisture for 300 hours at room temperature and 85% humidity.

A bright idea for recycling rare-earth phosphors from used fluorescent bulbs      (via sciencedaily.com)     Original source 

Recycling facilities collect glass and mercury from thrown away fluorescent bulbs, but discarded lighting could also supply rare-earth metals for reuse. The 17 metals referred to as rare earths aren't all widely available and aren't easily extracted with existing recycling methods. Now, researchers have found a simpler way to collect slightly magnetic particles that contain rare-earth metals from spent fluorescent bulbs.

Black carbon sensor could fill massive monitoring gaps      (via sciencedaily.com)     Original source 

Black carbon is up to 25 times more hazardous to human health than other airborne particles of a similar size. Standard sensors are expensive and burdensome, resulting in sparse coverage in regions infamous for poor air quality, such as the greater Salt Lake City area. A University of Utah-led study found that a portable, more affordable sensor recorded black carbon concentrations as accurately as the most widely used instrument for monitoring black carbon in real time. The portable sensor could help expand an accurate observation network to establish disease risk and create effective public health policies.

Scientists assemble a richer picture of the plight and resilience of the foothill yellow-legged frog      (via sciencedaily.com)     Original source 

Up to only a few inches in length, with a lemon-hued belly, the foothill yellow-legged frog may seem unassuming. But its range once stretched from central Oregon to Baja California. In 2023, it was listed under the federal Endangered Species Act. Its rapidly decreasing range is due in part to a fungal pathogen called Batrachochytrium dendrobatidis, or Bd, that has devastated amphibians around the world.

Reforestation schemes are not enough to recover the carbon created by harvesting wood      (via sciencedaily.com)     Original source 

Forests have a critical role to play in capturing and storing carbon from the Earth's atmosphere -- but some models exaggerate their carbon removal potential by almost three-fold, according to a leading professor of forest economics.
