Abstract: A simple, rapid test is described that measures contact nucleation of supercooled water. Application of this contact-nucleation test at ?3C to over 1000 organic compounds resulted in only 47 that could be considered as ...

Abstract: Only an extremely small fraction of the surface area of nucleants is effective in freezing supercooled water. The number of active sites per unit area for a specific nucleant material is shown to increase by a constant ...
