Type of article: Article

Summary

Pure water emulsions or water emulsions inseminated with ice nucleating particles were cooled and the velocity of an ultrasound wave passing through the sample recorded as a function of temperature. The proportion of ice was determined from the ultrasound velocity measurement. The results demonstrate the utility of ultrasound velocity measurements in monitoring ice nucleation in aqueous emulsions. Stirring the sample makes a significant difference to the ice nucleation rate.
