Surprisingly, the typical drivers of ozone formation—sunlight and warmth—played minimal roles. Instead, chemical reactions involving alkenes—particularly their ozonolysis—emerged as the ...

Specifically, the findings support the hypothesis that supernovae could have triggered two of the so-called "big five" mass ...

The ozone layer is on the mend, and it's thanks to human action. A new MIT-led study confirms - with 95% confidence - that global efforts to phase out ozone-depleting chemicals are paying off. This is ...

Often seen as destructive, supermassive black holes could help sustain life under specific conditions, scientists have found.

Fragranced products and cooking generate harmful nanoscale pollutants indoors, posing potential health risks. Purdue ...

This is due to the presence of colder temperatures, which facilitate the formation of polar stratospheric clouds. These clouds accelerate chemical reactions that break down ozone molecules.

At this scale, we can observe the earliest stages of new particle formation, where fragrances react with ozone to form tiny molecular clusters. These clusters then rapidly evolve, growing and ...

Rainfall triggers bursts of natural nanoparticles, which contribute to cloud formation and additional precipitation over the ...

In densely populated coastal areas, reactions of polluted air with sea salt aerosol from the ocean can lead to high surface ozone levels that affect air quality. Chlorine has become infamous for ...

Delhi experiences high levels of pollution throughout the year, not just in winter. Primary pollutants include dust and ozone ...
