Learning outcomes of the course unit

The Course of "Chimica Fisica dei Materiali Molecolari" is intended to provide
the fundamental elements of the chemistry-physics of molecular materials,
based on the basic concepts of solid state physics.

 D1 - Knowledge and ability to understand:
At the end of the course the student is expected to be able to
know the main intermolecular interactions in condensed matter,
know the basic concepts of crystalline solid state physics,
know the most recent research topics related to the research of molecular materials;
understand the mathematical language necessary for the description of physical and chemical phenomena
in crystalline systems.

 D2 - Ability to apply knowledge and understanding
The student will have the ability to
understand the relevant scientific literature,
understand the relationships between molecular structure, crystal packing and material properties,
analyze and classify the best experimental techniques for the characterization of materials,
with particular attention to spectroscopic techniques.

 D3 - Autonomy of judgment
The student will be able to analyze and evaluate independently
properties of molecular materials based on their molecular composition and on the
their crystalline arrangement.
He will be able to evaluate and choose the best experimental and theoretical techniques for
the study and characterization of materials.
 
D4 - Communication skills
The student will be able to communicate and comment on issues related to
properties and applications of molecular materials with physicists,
material scientists and engineers.

D5 -
The student will be able to deepen and extend their knowledge
using bibliographic resources, scientific articles and reviews on more specialized subjects.

Extended written notes are provided for the first part of the course.
Selected scientific review papers will be indicated regarding the topics of the second part of the course.

Teaching methods

The course of 48 CFU will mainly use lectures and heuristic lessons to stimulate students following day by day the topics discussed.
In the second part of the course we will also use workshop lessons.

Assessment methods and criteria

Oral exam to evaluate knowledge, comprehension skills and critical understanding, The exam is divided into two questions, one on a specific topic chosen by the student that must be deepened and organized by the student himself and a second one on a more general topic concerning the basics of solid state physics.
