Abstract:The oxidation of alkyl-substituted aromatic molecules produces oxygenated volatile organic compounds (OVOCs) and secondary organic aerosols (SOA) that are major components of ambient urban air. Despite their ubiquity, the impacts of variable ambient conditions, such as relative humidity (RH) and actinic exposure, on the physicochemical processes that contribute to SOA formation are still the subject of ongoing research and refinement. In this work, we perform laboratory environmental chamber experiments and us… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
