We propose that the photochemical smog mechanism produced substantial ozone (O3) in the troposphere during the Proterozoic, which contributed to ultraviolet (UV) radiation shielding hence favoured the ...

Theoretical treatment of ozone forming reaction is developed within the framework of mixed quantum/classical dynamics. Formation and stabilization steps of the energy transfer mechanism are both ...

This week, NASA and NOAA announced that 2017’s ozone hole, at 7.6 million square miles, was the smallest since 1988. Ozone is a molecule made of three oxygen atoms bonded together.

Carbonyl compounds are a class of oxygen-containing volatile organic compounds that are important precursors of the formation of O 3 and secondary organic aerosols (SOAs), these compounds can ...

The sea surface microlayer (SSML) is often present at the ocean interface and provides a unique environment for chemical reactions to occur. One such reaction is the heterogeneous oxidation of the ...

An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and ...

Bracing seaside air may not be so healthy after all. The mix of sea salt, ship fumes and city smoke leads to a chemical reaction that encourages the formation of ozone smog. A team led by James ...
