Recently a new paper titled “Effect of Aerosol-Phase State on Secondary Organic Aerosol Formation from the Reactive Uptake of Isoprene-Derived Epoxydiols (IEPOX)” by Dr. Jason Surratt’s group and Dr. Ault’s group has been accepted in Environmental Science and Technology Letters Check it out!
This study investigated how aerosol-phase state plays an important role in reactive uptake processes by quantify uptake coefficient of IEPOX on acidic ammonium sulfate particles coated with secondary organic aerosol (SOA) derived from α-pinene ozonolysis. The Ault lab used atomic force microscopy (AFM) and scanning electron microscopy (SEM) to study the morphology of α-pinene SOA particles, and confirmed phase separation.
