Physical chemistry of dispersed systems
The course is an introduction to the physical chemistry of finely dispersed systems. These systems are largely adopted in process engineering (environmental remediation, formulation chemistry, synthesis of pigments and catalysts) as well as in the production of different kinds of materials (biomaterials, ceramics, polymers and soft matter). The transformations in the dispersed state are strongly influenced by the high surface energy of the system and their study needs a peculiar approach, capable of linking information from the microscopic structure of the interface and the macroscopic global properties of the dispersion. The course begins with the macroscopic description of the interface provided by surface mechanics and thermodynamics, and subsequently moves towards the aspects related to the smallest scales: surface forces, charge separation and structure of interfaces. Finally, the modes of evolution of a disperse phase are examined and the population balance method is introduced, as a tool to predict the dynamics of a disperse system.
Statistical mechanics for chemical engineering
This course is an engineering introduction to statistical mechanics. After a recap on the Hamiltonian and Lagrangian formalism and on wave mechanics some basic elements of quantum mechanics will be discussed. Simple examples, such as the particle-in-a-box model and the quantum harmonic oscillator, will be presented. Then the concepts of canonical ensemble and partition function will be introduced, together with the relationship with the most important thermodynamic quantities: internal energy, entropy, pressure, Helmholtz and Gibbs free energies and chemical potential. The course will conclude with the microscopic interpretation of thermodynamic principles and of chemical equilibrium. Practical hands-on sessions with a molecular dynamics code are also planned.

Physical chemistry of dispersed systems
The aim of the course is to provide students with the basic knowledge necessary to understand the main phenomena occurring in heterogeneous finely dispersed systems, and to quantitatively predict and control their dynamics. At the end of the course the student should know the main mechanisms of evolution of a dispersion and be able to select proper methods to control or modify the size distribution and the morphology of a disperse phase.
Statistical mechanics for chemical engineering
At the end of the course the students will master basic concepts of quantum and statistical mechanics, will be able to understand the true molecular nature of chemical phenomena, described by the principle of thermodynamics. Students will also be able to apply these concepts to the practical atomistic and molecular simulations for the predictions of transport and equilibrium properties.

Physical chemistry of dispersed systems
The exam is aimed at ascertaining the knowledge of the subjects listed in the course syllabus and the ability to apply the theory and related calculation methods to practical applications. During the course, students must submit three calculation reports, which cover the main applications of the course. The submission of these reports within the prescribed deadlines is mandatory to access the written exam. The written part of the test contains short theoretical questions to ascertain the knowledge of the basic aspects of the subject, and simple numerical problems to verify the ability to quantitatively predict the response of a system. No notes, handouts or books may be kept or consulted during the test. The result of the exam is communicated on the teaching portal, together with the date on which the students can view the test and give the optional oral exam. After the written test, the exam can be concluded (in this case the maximum grade is 27/30) or can be continued with an additional oral exam, which aims at evaluating in depth the comprehension of the subject and the ability to apply the theoretical results.
