Research Abstract

Ice nucleation over nanosized TiO2 fine particles was studied as a model of aerosol which contributes artificial cloud formation at high temperature, especially over superhydrophobic surfaces of TiO2 under UV light irradiation. A home-made instrument was used for examining initial temperature of ice nucleation, providing a surprising result that the temperature of ice nucleation over TiO2 fine particles was lowered by UV light irradiation.
