Temporal evolution of charged and neutral nanoparticle concentrations during atmospheric new particle

E. Rohan Jayaratne, Buddhi Pushpawela, Lidia Morawska

Frontiers of Environmental Science & Engineering 2016, Volume 10, Issue 5, doi: 10.1007/s11783-016-0862-x

Abstract: In 50 events, charged and neutral particles were not formed at the same time.In 42 of these events the charged particles formed before the neutral particles.particles often occurred before that of neutral particles.While the charged particles were more likely to form before the neutral particles, once formed, the growthrate of the particles did not depend on their charge.
