Interfaces: Thermodynamics and Applications

This lecture delves into the thermodynamics of interfaces, focusing on the energy required to form and maintain surfaces, as well as the concept of work of addition. The discussion extends to multiple surface interfaces, Young's theorem, and the implications of contact angles in various materials. The instructor emphasizes the importance of understanding these concepts in material science, showcasing applications such as capillarity, composite material fabrication, and self-cleaning surfaces based on surface energy principles.
