Physical Chemistry of Disperse Systems and of Interfaces
A.Y. 2019/2020
Learning objectives
The goal of the course is to provide a general frame-work of the different physico-chemical aspects of surfaces and interfaces also with reference to the numerous experimental applications of these systems.
Expected learning outcomes
The student becomes familiar with the general principles ruling the interfacial reactivity in the different systems. He further learns by which kind of experimental measurements he might obtain a complete characterization of such systems, also on the grounds of experiments performed personally in the laboratory.
