Triboelectrification excited by breathing continuously replenishes electrostatic charges, endowing the self-charging face mask with an ultralong service lifespan
Isotopic constraints reveal the significant contributions of combustion-related sources to ammonia emissions
By integrating nitrogen isotope systematics of ammonia emissions and transformations in the atmosphere, this study quantified the combustion-related ammonia emission and uncovered its importance for mitigating strategies of ammonia pollution.
Reactive Metal Boride Nanoparticles Trap Lipopolysaccharide and Peptidoglycan for Bacteria-Infected Wound Healing
Antibacterial wound healing approaches often target bacteria but overlook the inflammation response caused by products released by dead bacteria. The authors develop MB nanoparticles to prevent both infection and excessive inflammation by trapping the key component of bacteria, LPS/PGN.
We found that the risks of outcomes indicating severe disease were lower or similar for those infected with BA.2 sub-lineage of Omicron, compared to BA.1, after controlling for confounding factors.
An innovative framework is developed to infer rainfall interception loss (Ei) from flux tower measurements and upscale to the globe. Globally, ~8.5% of land rainfall is recycled to the atmosphere as Ei, and this ratio is decreasing because rainfall is getting more intense and less frequent.
