Abstract:

The theoretical study of condensation nuclei has been hampered by the fact that one must know the vant Hoff i-factors for a particular nucleus at different concentrations as a result, only sodium chloride has been studied extensively. In this report, a generalized expression for the solution effect on droplet growth is used, thus simplifying the study of the growth behaviors of a large number of promising condensation nuclei under equilibrium conditions. Tables are compiled to present their equilibrium growths and their physical properties, and a few graphs comparing these properties are included to illustrate how the data in these tables may be used. It is believed that the information presented herein will facilitate an intelligent selection of the proper artificial nuclei for the modification of warm fogs and clouds, when combined with adequate measurements of the pertinent environmental parameters.
