"Classical nucleation theory (CNT) is the most common theoretical model used to quantitatively study the kinetics of nucleation. Nucleation is the first step in the spontaneous formation of a new thermodynamic phase or a new structure, starting from a state of metastability. The kinetics of formation of the new phase is frequently dominated by nucleation, such that the time to nucleate determines how long it will ta… " - Nucleation thermodynamics
