Aims

Knowledge concerning the properties of matter and their understanding from the corpuscular/molecular scale.
Know-how in physical chemistry: quantification, conceptualisation, modelling.
Development of an adequate attitude towards the understanding of the properties of matter and their command.

Main themes

Implementation of two complementary physico-chemical approaches for the forecast and the command of properties of matter

Macroscopic properties and molecular interpretation
- Kinetics: Knowledge of fundamental laws regulating the progress of chemical reactions// Interpretation of kinetics experimental data to deduce reaction mechanisms.
- Phase equilibria: Study of phase equilibria of condensed systems (liquid/liquid; liquid/solid) and of liquid/vapor systems with several constituents: interpretation and use of phase equilibrium diagrams // Thermodynamic study of nonideal systems with several constituents (solutions): use of thermodynamic tools for solving phase equilibrium problems.
Properties of particles and forecast of macroscopic properties - Statistical mechanics.
Basic concepts // Application to gaseous systems // a priori calculations of thermodynamic quantities // Application to chemical free energy // Notions of non-equilibrium thermodynamics.
