CHIMICA FISICA DEI SISTEMI COMPLESSI
Oral exam. No partial tests are planned. The student my opt to give the exam either in Italian or in English.
Students shall demonstrate to have learned the fundamentals of formulation physical chemistry and of its relevant models.
Class will provide an introduction to formulation chemistry. The aim will be of overcoming the empirical approach to formulations, thinking them as actual instantiations of complex systems.
Definition of formulation.
Fundamentals of surface thermodynamics.
Physical chemistry of surfactants.
Static and dynamic properties of formulations.
Examples of formulations in chemistry.
What is the formulation chemistry and why it matters. Conceptual ingredients of formulations. Formulations as instances of complex chemical systems. Interplay among additives. Surfactants as key players in formulation chemistry. Statement of the formulation problem and of its modelling needs. Thermodynamics of small systems: interfaces and micelles as dimensionally constrained systems; wettability and adsorption. Stability and response of dimensionally-constrained open systems to perturbations: application to interfaces and micelles. Effective medium theories: static and dynamic (transport) properties. Elements of additive chemistry: surfactant types, their chemical structure and physical properties. Examples of formulations. Non-detergency-related formulations. Manufacturing and economic issues.
