Explore the fascinating world of inhomogeneous fluids in this comprehensive lecture on non-equilibrium dynamics. Delve into the unique phenomena arising from interfaces in confined liquids, examining how surface presence affects both static properties and dynamics compared to bulk fluids. Learn about molecular dynamics simulations and numerical calculations for colloidal particles in binary solvents. Cover topics such as phase transitions, critical points, hot colloids in near-critical solvents, and experimental-theoretical analogies. Investigate models, results, and experimental findings for colloids in confinement. Discuss binary liquid mixtures in slits, interdiffusivity, coalescence preference dynamics, nucleation, droplet motion and growth, and aging phenomena. Gain valuable insights into the complex behavior of inhomogeneous fluids through this in-depth exploration of their non-equilibrium dynamics.
