Elusive compounds of greenhouse gas isolated

19-Sep-2019

Nitrous oxide (N2O) is a potent atmospheric pollutant. Although naturally occurring, anthropogenic N2O emissions from intensive agricultural fertilisation, industrial processes, and combustion of fossil fuels and biomass are a major cause for concern. Researchers at the University of Warwick have ...
