Applied physical chemistry (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 population balance method is introduced, as a tool to predict the dynamics of a disperse system.

Finally, the modes of evolution of a disperse phase are examined and population balance method is introduced, as a tool to predict the dynamics of a disperse system. The second part of the 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 of 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 commercial (molecular dynamics) simulation suite are also foreseen.

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. In particular, at the end of the course the student should know the main evolution mechanisms of a dispersion and be able to select proper methods to control or modify the size distribution and the morphology of a disperse phase.

As far as the second part of the course is concerned, 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.

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 six 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 lasts approximately two hours. It 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.

In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
