โฆ Synopsis
Time-dependent measurements of the velocity of ultrasound at constant temperature in hydrocarbon-in-water emulsions containing a mixture of solid and liquid droplets show that crystallization is induced in liquid droplets when solid droplets are present. We suggest that this may be caused by the solid droplets colliding with liquid droplets and initiating crystallization within them.

## Abstract The mass transfer of hydrocarbons within an emulsion drop has been modeled. The selective behavior of the process is attributed to the controlling effect of the aqueous phase; calculations show that the presence of a very thin membrane of water separating the inner core of the hydrocarb
Droplet collision is shown to be important in the propagation of nucleation through supercooled oil-in-water emulsions by the use of a novel membrane technique. On the other hand, nucleation mediated by Tween 20 micelles is shown to be of relatively much less importance in both n-hexadecane and coco
