Ice nucleation rates near ∼225 K.

摘要: We have measured the ice nucleation rates, Jice, in supercooled nano-droplets with radii ranging from 6.6 nm to 10 and droplet temperatures, Td, 225 K 204 K. The initial temperature of water droplets is ∼250 K, i.e., well above homogeneous for micron sized droplets, TH ∼235 rates increase systematically ∼1021 cm−3 s−1 ∼1022 this range, overlap Manka et al. [Phys. Chem. Phys. 14, 4505 (2012)], suggest that experiments larger would extrapolate smoothly Hagen [J. Atmos. Sci. 38, 1236 (1981)]. sharp corner rate data as drops is, however, difficult match available theory even if we correct classical physical properties high internal pressure nanodroplets.
