Sandia National Laboratories researchers Lisa Deibler and Arthur Brown had a ready-made problem for their computer modeling work when they partnered with the National Nuclear Security Administration´s Kansas City Plant to improve stainless steel tubing that was too hard to meet nuclear weapon requirements. When steel is too hard it becomes brittle, so the plant ended up getting new tubing. However, Deibler said KCP needed a backup in case it couldn´t find replacements in time to...

If you thought antifreeze was only something that was necessary to keep your car from freezing up in the winter, think again. Plants and animals living in cold climates have natural antifreeze proteins (AFPs) which prevent ice growth and crystallization of organic fluid matter. Without such antifreeze, living matter would suffer from frost damage and even death. Production of such antifreeze proteins is one of the major evolutionary routes taken by a variety of organisms, including fish,...

KINGSTON, ON "“ The same antifreeze proteins that keep organisms from freezing in cold environments can also prevent ice from melting at warmer temperatures, according to a new Queen's University study. The study presents the first direct measurements of the superheating of ice crystals in antifreeze protein solutions. Superheated ice crystals can be stabilized above the melting point for hours, at a maximum temperature of about +0.5 degree Celsius. "You can hold the ice crystal at...

Scientists publish first direct measurements of 'superheating' phenomenon The same antifreeze proteins that keep organisms from freezing in cold environments also can prevent ice from melting at warmer temperatures, according to a new Ohio University and Queen's University study published today in the Early Edition of the journal Proceedings of the National Academy of Sciences. Antifreeze proteins are found in insects, fish, bacteria and other organisms that need to survive in cold...
