Supercool Liquids Stay Liquid Below Freezing

Aug-13-18 Keeping liquids liquid at below freezing temperatures could offer a way to extend the preservation times of organs and tissues.

Developed by a team at Massachusetts General Hospital, the novel method is intriguing in its simplicity. Building on the knowledge that freezing begins at the liquid’s surface, the team kept the air and water separate by covering the surface of the water with a hydrocarbon-based oil. The process, which the team calls ‘deep supercooling,’ blocks the interaction between the water and air and keeps crystallization from forming.

According to O. Berk Usta, co-corresponding author of the study, "This surprisingly simple, practical and low-cost approach to supercooling solutions for extended periods can enable many medical and food preservation methods, as well as fundamental experiments that were not previously possible."
