Overview
Thermodynamic properties of fluid-fluid and fluid-solid interfaces; adsorption at interfaces, capillarity, Laplace equation, Ostwald ripening, contact angles, interfacial instabilities.
Surfactant and polymer solution thermodynamics, molecular structure and phase diagrams/mesophases.
Mechanical and transport properties of interfaces and mesophases.
Behaviour of complex systems involving interfaces and adsorbed surfactant layers: emulsions and microemulsions.
Mechanism of crystallization, kinetics and process design of crystallization.
Applications to industrial processes.
Aims
The unit aims to:
- Introduce the science underlying colloidal and interfacial phenomena;
- Show how interfaces in heterogeneous mixtures are of importance in the understanding of structure, stability and transfer processes.
