We follow the nucleation of n-alcohols, n-propanol through n-pentanol, in two sets of supersonic nozzles having differing linear expansion rates. Combining the data from static pressure trace measurements with small-angle X-ray scattering we report t

We make direct measurements of stationary, homogeneous nucleation rates, J = N/Δt, in supersonic Laval nozzles. We determine the number densities, N, of droplets formed from small-angle neutron scattering (SANS) experiments and the time intervals du

Small angle neutron scattering (SANS) experiments were used to characterize binary nanodroplets composed of D2O and H2O. The droplets were formed by expanding dilute mixtures of condensible vapor in a N2 carrier gas through a supersonic nozzle, while

We examined the condensation of H2O, D2O, and four intermediate mixtures (20, 40, 60, and 80 mol % D2O) in a supersonic nozzle. Because the physical and chemical properties of protonated and deuterated water are so similar, this system is ideal for s

Very recently, Wolk and Strey [J. Phys. Chem. B 105, 11683 (2001)] presented empirical temperature correction functions for calculating homogeneous nucleation rates J of H2O and D2O (1

Nucleation rates of n-propanol were investigated in the Laminar Flow Diffusion Chamber. Nucleation temperatures between 270 and 300 K and rates between 10(0) and 10(6) cm(-3) s(-1) were achieved. Since earlier measurements of n-butanol and n‑pentan

In the past century, the homogeneous nucleation of light water (H2O) has repeatedly been studied using various experimental techniques. Generally, the onset of nucleation was recorded, while less f...

We study the co-condensation of nonane and D2O in a supersonic flow, using small angle X-ray scattering to characterize the size and number density of the aerosol and Fourier Transform Infrared Spectroscopy to determine the composition. Under our exp

New measurements of homogeneous nucleation onset data for argon and nitrogen from the cryogenic nucleation pulse chamber have been performed. By reducing the amount of carrier gas in the gas mixture, higher onset pressures and temperatures could be r

We provide a brief overview of the extensive scientific research that has been conducted to determine the degree to which pure water can be supercooled and the rates at which the relevant phase transitions occur. Beginning with condensation, we prese
