Thermodynamics: Surface Energy

This lecture covers the concept of surface energy in thermodynamics, focusing on the Gibbs free energy and its relation to surface tension. It explains how the surface energy contributes to the overall Gibbs free energy and discusses the implications of surface tension on material properties. The lecture also delves into classical and non-classical nucleation theories, highlighting the differences between them and their impact on crystallization processes. Additionally, it explores the thermodynamic model of precipitation using the example of calcium carbonate, discussing equilibrium constants, activity coefficients, and hydrated ionic diameters. The lecture concludes with a discussion on Brownian motion, diffusion coefficients, and the importance of precipitation processes in ceramic production.
