[Webinar] Thermodynamics of interfaces

In this lecture, I will first introduce some concepts related to the definition of an interface, long range surface forces, disjoining pressure and adsorption. In the second part, I will discuss some aspects of the physics of wetting. Energetics of: a) liquid drops on solid substrates and b) solid particles at liquid interfaces, will be described in different length scales: from the macroscopic down to the nanoscale. Finally, I will describe the stability of a liquid foam, considered as an interfacial material rather than a gas in liquid dispersion.
