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.
