    Notes: We present measurements of binary homogeneous nucleation of sulfuric acid and water vapors at 298 K at two different relative humidities (38.2% and 52.3%), H2SO4 vapor concentrations ranging from about 1⋅1010 to 3⋅1010 molecules/cc. The experimental setup consisted of a turbulent mixing unit combined with a flow chamber where the nucleation took place. Particular attention was paid to the generation of sulfuric acid vapor. The measured nucleation rates vary between about 2 and 3000 cm−3 s−1. The results are compared with other measurements found in the literature. Our experimental rates are in agreement with predictions of the revised classical nucleation theory incorporating the hydration effect. © 1997 American Institute of Physics.

    Homogeneous nucleation of n-pentanol in a laminar flow diffusion chamber (2001)

    Notes: Nucleation rate isotherms of n-pentanol were measured in laminar flow diffusion chamber. n-pentanol was chosen for nucleating vapor and helium for carrier gas as a part of a world wide joint experiment on homogeneous nucleation. Experimental temperature range was from 260 to 290 K. Experimental nucleation rate range was from 103 to 107 cm−3 s−1. The results were compared to the classical nucleation theory and experimental data found in literature. Experimental results were three orders of magnitude higher than predicted by the theory. The difference was constant over the whole experimental range. The saturation ratio dependency of nucleation rate was well predicted by the theory. The number of molecules in the critical clusters was quite consistent with the theory. The results were in reasonable agreement with data found in literature. © 2001 American Institute of Physics.
