Highly oxygenated organic molecules are a key component of atmospheric secondary organic aerosol. However, the origin and formation mechanism of highly oxygenated organic molecules with high ...

Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a ...

For decades, scientists have known that soot particles play a pivotal role in forming contrails. When the atmospheric ...

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 ...

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 ...

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 ...

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 ...
