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 ...

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 ...

Billions upon billions of soot particles enter Earth’s atmosphere each second, totaling about 5.8 million metric tons a year — posing a climate-warming impact previously estimated at almost one-third ...

A better understanding of how hydrocarbons burn is an important topic in environmental science, with nanoparticles of unburnt soot being active agents in climate change and detrimental to human health ...
