TL;DR: Three separate size regimes below 2-nm diameter are identified that build up a physically, chemically, and dynamically consistent framework on atmospheric nucleation—more specifically, aerosol formation via neutral pathways.
Journal ArticleDOI
Formation of oligomers in secondary organic aerosol.
Michael P. Tolocka,Myoseon Jang,Joy M. Ginter,Frederick J. Cox,Richard M. Kamens,Murray V. Johnston +5 more
TL;DR: Chemical reactions leading to oligomer formation provide a reasonable answer to a difficult problem associated with secondary organic aerosol production in the atmosphere as Polymerization provides a mechanism by which partitioning to the particle phase becomes favored.
Journal ArticleDOI
Measurement and numerical simulation of soot particle size distribution functions in a laminar premixed ethylene-oxygen-argon flame
Bin Zhao,Zhiwei Yang,Murray V. Johnston,Hai Wang,Anthony S. Wexler,Michael Balthasar,Markus Kraft +6 more
TL;DR: In this article, the soot particle size distribution function (PSDF) was measured in a laminar premixed ethylene-argon-oxygen flame (φ = 2.07) using a scanning mobility particle sizer.
Journal ArticleDOI
Analysis of Soot Nanoparticles in a Laminar Premixed Ethylene Flame by Scanning Mobility Particle Sizer
TL;DR: In this article, the authors developed an in situ sampling technique to follow the evolution of nanoparticles formed in flames in a spatially resolved manner, and the effect of dilution on particle losses in the sample probe was systematically studied.
Journal ArticleDOI
Chemical species associated with the early stage of soot growth in a laminar premixed ethylene–oxygen–argon flame
TL;DR: In this paper, the roles of aliphatic and aromatic chemical species in soot mass growth were studied in a burner-stabilized premixed ethylene-oxygen-argon flame.
