| Aims |
Knowledge of:
- Concepts allowing the understanding of physico-chemical phenomena typical of dispersed systems (surfaces, colloids, nanometer-scale and supramolecular systems).
- Incidence of such concepts on the behaviour of systems at the macroscopic scale.
Know-how:
- Ability to establish relationships between phenomena occurring at different scales (nano, micro, macro)
- Developing curiosity towards the understanding of matter and the link with applications (materials, food, living organisms, soils, environment, chemical industry
).

| Content |
Introduction: overview of colloidal systems and interfaces. Kinetic theory of colloidal systems: sedimentation, centrifugation, diffusion, Brownian movement. Surface energy: surface tension, Laplace equation, wetting - capillarity - adhesion - cohesion - dispersion, porosimetry, illustrations. Thermodynamics in solution: Gibbs-Duhem equation, osmotic pressure. Adsorption from solution: properties of monolayers, adsorption, Gibbs equation, Langmuir isotherm, illustrations. Donnan equilibrium: ion distribution, osmotic pressure, potential, relationship with classical electrochemistry, illustrations. Properties of charged surfaces: origin of charge, physical and chemical models of the double layer, interactions between particles and stability of colloidal systems.
