If you've ever waited on an airport runway for your plane to be de-iced, had to remove all your food so the freezer could defrost, or arrived late to work because you had to scrape the sheet of ice off your car windshield then you know that ice can cause major headaches. Researchers have created a surface that can significantly delay frost formation, even at temperatures as low as 6 degrees Celsius below freezing.
The surface is biphilic, meaning it repels water in some areas and attracts it in others.Image credit: Dr. Amy Betz, Mechanical and Nuclear Engineering, Kansas State University
