Aims
At the end of this learning unit, the student is able to : | |
| 1 |
At the end of the course, the student will be able to: - Rephrase the concepts which allow understanding physico-chemical phenomena involving dispersed systems and interfaces (surfaces, colloids, nanometer-scale and supramolecular systems), and their impact on the behavior of such systems at the macroscale; - Evaluate the consequences of these phenomena, based on realistic numerical values; - Establish links between phenomena occurring at different scales (nano, micro, macro); - Explain phenomena observed in daily life or in typical bioengineering applications (materials, food, living systems, soils and environment, chemical industries, biotechnology) on the basis of concepts developed in the course; - Predict the behavior of simple systems. |
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.
Adsorption from solution: properties of monolayers, adsorption, Gibbs equation, Langmuir isotherm, illustrations.
Properties of charged surfaces: origin of charge, physical and chemical models of the double layer, interactions between particles and stability of colloidal systems.

Teaching methods
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
Lectures illustrated by experimental observations and mixed with the resolution of numerical exercises.In reason of the limited number of places in classrooms this year (COVID-19 crisis), some of the lectures may be given remotely.
Evaluation methods
Due to the COVID-19 crisis, the information in this section is particularly likely to change.
During the semester: tests on limited parts of the course (25% of final grade). At the end of the semester: written exam, including an open book question (75% of final grade).
