TL;DR: In this article, the compositions of small NH3-H2SO4 clusters over a wide range of atmospherically relevant environmental conditions were mapped out, supporting previous evidence for acidbase reactions being the essential mechanism behind the formation of these clusters under atmospheric conditions and up to sizes of at least 2 nm.

TL;DR: In this article, the authors presented the first experimental survey of new particle formation (NPF) rates spanning free tropospheric conditions, and compared these experimental data with calculated cluster formation rates from the Atmospheric Cluster Dynamics Code with cluster evaporation rates obtained from quantum chemistry using data obtained in the European Organization for Nuclear Research CLOUD (Cosmics Leaving OUtdoor Droplets) chamber.

TL;DR: In this paper, the authors performed chamber experiments designed to study the contributions of sulfuric acid and organic vapors to the formation and early growth of nucleated particles and found that both condensation of oxidized organic compounds and reactive uptake contribute to particle growth.

TL;DR: In this paper, two continuous-flow condensation particle counters (CPCs) using diethylene glycol (DEG) as the working fluid were developed for particle detection.

TL;DR: It appeared that, after the formation of the clusters containing three molecules of sulfuric acid, the clusters grow at a similar speed, independent of their charge, and the growth rate is then probably limited by the arrival rate of sulfurIC acid or cluster-cluster collision.
