TL;DR: In this article, the authors used PTR-MS to monitor the time evolution and yields of SOA and gas-phase oxidation products using HC:NO_x ratios to detect terpene photooxidation.

TL;DR: As the seed particle acidity increases, larger oligomers are formed more abundantly in the SOA; consequently, the overall SOA yield also increases, and this explicit effect of particle phase acidity on the composition and yield of SOA may have important climatic consequences and need to be considered in relevant models.

TL;DR: In this paper, the authors present laboratory chamber studies of the reactive uptake of simple carbonyl species (formaldehyde, octanal, trans,trans-2,4-hexadienal, glyoxal, methylglyoxal and 2,3-butanedione) onto inorganic aerosol.

TL;DR: This study studies the general mechanisms of SOA formation by comparing aerosol growth and gas-phase concentrations and finds that all the hydrocarbons studied can be classified into two groups based entirely on the number of double bonds of the hydrocarbon, regardless of the reaction systems (ozonolysis or photooxidation).

TL;DR: In this article, a proton transfer reaction mass spectrometer (PTR-MS) was used to monitor the evolution of gas-phase products, identified by their mass to charge ratio (m/z).
