The National Science Foundation (NSF) Division of Chemistry awarded a $647,623 Project Grant to The Pennsylvania State University (Penn State) under the Mathematical and Physical Sciences program (CFDA 47.049) to study the surface characteristics that drive heterogeneous ice nucleation. Over the 3-year award period from September 1, 2023 to August 31, 2026, Professor Miriam Freedman and her graduate and undergraduate students will investigate how atmospheric particles catalyze cloud formation and the molecular-level processes behind ice nucleation. The research will examine the role of surface features, composition, and hydrogen bonding in inorganic, organic, and biological ice nucleating particles using techniques like immersion freezing. The project aims to provide a framework for understanding critical surface factors that promote ice nucleation, which is important for improving atmospheric models. The work will provide valuable research experiences for undergraduate students and incorporate findings into course lectures, while also engaging the wider community through public outreach activities.
