    Ice formation occurs at higher temperatures when an ice-nucleating particle is at the water surface compared to when it is inside. This surface nucleation is significantly faster than bulk nucleation, supporting new theories of ice crystallization.

    Area of Science:

    • Atmospheric chemistry
    • Physical chemistry
    • Materials science

    Background:

    • Investigating the influence of substrate proximity on ice nucleation in undercooled water.
    • Understanding the role of interfaces in phase transitions.

    Discussion:

    • Laboratory observations show higher freezing temperatures when ice-forming nuclei are near the water surface versus immersed.
    • Nucleation rate at the water surface is 10^10 times greater than in bulk water.
    • This supports homogeneous surface crystallization theories.

    Key Insights:

    • Classical nucleation theory analysis reveals a ~2-fold decrease in the free energy of critical ice germ formation at the interface.
    • The jump frequency of molecules from liquid to solid phases is significantly enhanced at the air-water interface.
