A review of nucleation models in various systems

Popis výsledku v původním jazyce

We summarize thermodynamic and kinetic aspects of homogeneous and heterogeneous nucleation in vapor-liquid, vapor-solid, and liquid-solid phase transitions. Cluster formation plays an important role in phase transition process and is pivotal in the formation of new substances. Nuclei of a new phase (supercritical clusters) form after overcoming the nucleation barrier W∗ at the criticalsize i∗. Even though the various systems are considered, some general features are common. The probability of nucleation is exponentially proportional to the nucleation barrier [i.e. P ∝ exp(−W∗)], so the probability of heterogeneous nucleation is higher than that of homogeneous nucleation under the same conditions because the heterogeneous nucleation barrier is often lower than the homogeneous nucleation barrier. However, the formation of nuclei also depends on nucleation kinetics. In some cases, homogeneous nuclei can form preferentially over heterogeneous nuclei, even though homogeneous nucleation has a higher nucleation barrier. In small, encapsulated systems, the formation of nuclei reduces the number of atoms or molecules (the building blocks of the newly forming phase) in the parent phase. This results in a decrease in supersaturation, which influences the nucleation process. Thus, the nucleation barrier changes over time so, predictions based on the classical nucleation theory are inappropriate in these cases. All of these aspects must be considered.
