A Laminar Flow Tube Reactor (LFTR) has been used as a quantitative tool for nucleation measurements. It has been specially designed and constructed in order to minimize the potential experimental inaccuracies. Careful attention has been paid to the temperature conditions inside the LFTR. Other sources of experimental uncertainties, such as initial vapor concentration conditions, calculations of the parameters of the nucleation zone, and particle concentration measurements have been thoroughly analyzed as well. The nucleation rate dependence as a function of supersaturation and temperature has been measured for the dibutyl phthalate, ethylene glycol, and glycerol. The experimental results have been compared with the other experimental data and with the theoretical predictions.

Then we induce the phase transition by a rapid pressure quench under simultaneous detection of pressure and scattered light. To this...

    The formation of ice particles from liquid aqueous aerosols is of central importance for the physics and chemistry of high altitude clouds. In this paper experimental measurements and theoretical models of ice nucleation from concentrated aqueous solutions are reviewed. Both homogeneous as well...

    Airborne measurements in clouds at -10 to -30°C often show concentrations of ice crystals much greater than would be predicted from ice nuclei (IN) measurements made at or below 2% supersaturation with respect to liquid water (SSw). There may be small regions of such clouds where cloud...
