The National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded Virginia Polytechnic Institute & State University $445,401 on August 15, 2026, under the Engineering program (CFDA 47.041) to conduct collaborative research on thermal transport in supercooled droplet freezing on superhydrophobic and ultrasonically vibrating surfaces for de-icing applications. The project will analyze freezing processes when supercooled water droplets—which remain liquid below 0°C, staying liquid to as low as -40°C in laboratory conditions—impact cold surfaces, and will explore mechanisms to prevent or delay ice accumulation on aircraft and wind turbines. The research will employ ultra-fast X-ray and high-speed optical imaging to understand the physics of freezing nucleation when supercooled droplets impact various solid surfaces and will investigate how travelling ultrasonic structural waves interact with nucleation on superhydrophobic surfaces. The work addresses a gap in prior studies by examining both the fast transition to thermodynamic equilibrium in the first freezing stage and the slower solidification stage, as well as interactions between ultrasonic waves, superhydrophobic surfaces, and droplet impact that previous research did not investigate. The project will develop theory, methodology, and new experimental techniques for understanding nucleation and solidification of supercooled water droplets. The award includes educational components mentoring high school and college students in real-world engineering problem-solving using analytical laboratory tools. Performance occurs in Blacksburg, Virginia, with a period of performance through July 31, 2029.
