OVERVIEW

The term "soft matter" refers to those systems characterized by binding energies comparable to thermal energy and by the tendency of the constituents to spontaneously form mesoscopic structures. The course deals with the study of these systems, including colloids, polymers and liquid crystals, with particular attention to applications in biophysics and nanotechnology.

 

AIMS AND CONTENT

LEARNING OUTCOMES

The course is aimed to provide an introduction to the study of soft matter, which is characterized by weak interactions between nano-sized building blocks and important effects of thermal fluctuations. Students will acquire knowledge on the characteristic features of soft materials, the forces acting in these systems, the physical models which describe their behavior.

AIMS AND LEARNING OUTCOMES

At the end of the course, the student will be able to: understand the origin of the interactions that take place in soft matter and know their properties; recognize the different types of soft systems (colloidal suspensions, gels, liquid crystals ...); describe the behavior of polymeric molecules using models based on general physical properties; apply the concept of critical packing parameter in self-assembly processes; describe the conformational transitions occurring at the molecular level in a liquid crystal display; understand how the knowledge of the general properties of soft matter opens the way to the design of nanomaterials with specific desired properties.

The course can also be chosen by students of the Master Degree in Materials Science and Technology. In this context, the training activities and acquired skills are particularly suitable for the "Materials Scientist: Research Specialist" profile

PREREQUISITES

To effectively address the contents of the course, knowledge of the basic concepts of electromagnetism and statistical mechanics provided in the three-year degree course is advisable.

TEACHING METHODS

The course is based on traditional lectures (48 h).

EXAMS

EXAM DESCRIPTION

The exam consists of an oral test on the topics covered by the course. The detailed program of the topics is available on Aulaweb

ASSESSMENT METHODS

The oral exam is always conducted by the professor who is responsible for the course and by another expert in the subject (usually another professor). The oral exam takes about 50 minutes and consists of a fixed number of questions (the same for all students) on the course topics. It allows the commission to assess the student's level of understanding of the course topics and the student's ability to discern the validity limits of the models used. The assessment will take into account the quality of the presentation, the correct use of the specialist vocabulary, the ability to critical reasoning.
