Abstract Details

2010, PHD, Kent State University, College of Arts and Sciences / Department of Chemistry.
Ternary homogenous nucleation (THN) involving NH3, H2SO4, and H2O is suspected to play an important role in our atmosphere. Theoretical studies on THN involving NH3 predict much different results with respect to what the particle formation rates should be. Also, only a few laboratory experiments probing THN with NH3 have been performed, and these experiments have not fully characterized the THN nucleation process. The purpose of this study is to look at THN involving NH3 with a more in depth analysis. This proposed research will include: (1) characterization of the nucleation flow reactor; (2) determination of the wall loss for the gas phase species of NH3 and H2SO4; (3) describing the enhancement of nucleation rates when using THN with ammonia as compared to just binary homogenous nucleation (BHN) with just H2SO4 and H2O; (4) determining the number of NH3, H2SO4, and H2O molecules in the critical cluster; (5) determining the [H2SO4] required using THN to see particle formation.
