Surface Tension: Fundamentals and Applications

This lecture covers the fundamentals of surface tension, including the wettability of surfaces, vapor pressure, contact angles, and engineered hydrophobic surfaces. It also delves into adhesion forces, models of adhesion, and the impact of contact angles on vapor pressure. The lecture explores the Laplace-Young equation, capillary forces, electrostatic forces, Van der Waals forces, and their integrated forms for various geometries. Additionally, it discusses the adhesion force comparison, laser micromachining, and the role of surfaces in affecting physical properties of objects. The lecture concludes with a discussion on laser manufacturing technologies, including cutting, additive manufacturing, and laser eye surgery.
