SOA from biomass burning emissions

Ali published his work on modeling secondary organic aerosol (SOA) formation from biomass burning emissions in Environmental Science and Technology. He found that oxgyenated aromatics – and to a certain degree heterocyclics – contribute substantially to SOA! Fun fact – guaiacol, an important SOA precursor, is also responsible for the aroma in whisky or scotch.

SOA from biofuels

Charles published his work on chamber measurements and modeling in Environmental Sciences: Processes and Impacts to understand secondary organic aerosol production from evaporated biofuels. He found some proposed fuel molecules/mixtures to produce more SOA than regular gasoline. Co-Optima, take notice!

In two separate studies, we reported on properties and impacts of aerosol emissions from two different sources: diesel engines and residential cookstoves. In the work published in Atmospheric Environment, we determined the volatility of primary organic aerosol from a modern-day, non-road diesel engine. In the work published in Aerosol Science and Technology, we measured the emissions and radiative impacts of sub-10 nm particles from a range of dirty-to-clean cookstoves.
