Interfacial Phenomena: Nucleation and Growth

This lecture covers the interfacial phenomena related to nucleation and growth in materials science and engineering, focusing on the nucleation energy barrier, cluster size, and melting point depression. The instructor explains the concepts using equations and diagrams, illustrating the process of cluster formation and growth. Different approaches to understanding nucleation and growth are discussed, highlighting the importance of surface energy and cluster stability. The lecture concludes with a detailed explanation of the nucleation process and its impact on material properties.
