| Prerequisites |
Precursory courses : General physics, General chemistry, Introduction to thermodynamics (concept of free enthalpy)
|
| Main themes |
- Overview of colloidal systems and interfaces - Kinetic theory of colloidal systems: concepts, applications - Surface energy: concepts, applications - Adsorption: concepts, applications - Membrane-related phenomena: concepts, applications - Charged interfaces: physico-chemical models - Interactions between surfaces: concepts, applications
|
| 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.
