Particle phase photochemical oxidation of polycyclic aromatic hydrocarbons on soot can produce substantial amount of highly unsaturated and oxygenated organic aerosol. That changes soot to better ...

New study challenges current understanding of the formation mechanism of atmospheric secondary organic aerosol – Particle chemistry appears to have a strong influence on the climate impact of soot and ...

Haze is formed when a cocktail of various gaseous pollutants is oxidized and forms particulate matter diffusing sunlight. This process is mainly mediated by hydroxyl radicals (OH), and researchers ...

Analysis of in-flight emissions from an Airbus A350-900 using 100% sustainable aviation fuel indicates a reduction of 35% in soot particle numbers, and a halving of contrail ice-crystal formation per ...
