A new report from the Hong Kong Polytechnic University showed that alkene pollution from local petrochemical industries in China is causing higher than usual levels of ozone pollution. This has ...

Ozone pollution isn’t just a summer story anymore. In parts of northern China, high ozone levels are now appearing during winter—an alarming twist that defies decades of air quality science. This ...

Researchers have identified a surprising phenomenon: severe winter ozone (O₃) pollution in Lanzhou, China, primarily caused by alkene emissions from local petrochemical industries. Typically linked to ...

Measurements in a forest reveal a previously unknown atmospheric oxidant that acts as a source of sulphuric acid — one of the main precursors for the formation and growth of aerosol particles and ...

Chemical groups containing oxygen, nitrogen, silicon, and other heteroatoms often react during alkene coupling reactions, generating undesirable product mixtures. But a new, iron-catalyzed radical ...

A dilute solution of bromine is added to samples of heptane and cyclohexene. The bromination reactions and mechanisms are compared. UV light splits the bromine molecule into two reactive radicals, ...
