This lecture covers the fundamental concepts of dispersion forces, including Van der Waals forces, electrostatic interactions, and steric repulsion. It explains the total interaction energy between particles, the influence of dispersion interactions on material properties, and the interaction between instantaneous and induced dipoles. The lecture also discusses the dispersion interaction between particles, semi-infinite plates, and curved surfaces, as well as the measurement of interparticle forces using AFM. Additionally, it explores the attractive magnetic forces in ceramics and the role of superparamagnetism in biomedical applications.
