TL;DR: It is shown that NOx suppresses particle growth in general, but the suppression is rather nonuniform and size dependent, which can be quantitatively explained by the shifted HOM volatility after adding NOx.

TL;DR: In this paper, a part of this oxidation can proceed through an autoxidation process, which is an important source of secondary organic aerosol (SOA) in the atmosphere.

TL;DR: In this article, the authors present a characterization of the hygroscopic growth behavior and effects of different inorganic seed particles on the formation of secondary organic aerosols (SOA) from the dark ozone-initiated oxidation of isoprene at low NOx conditions.
