OVERVIEW

Soft materials are systems whose bond energies between constituents are comparable to thermal energy. They include colloids, polymers and liquid crystals.

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.

AIMS AND LEARNING OUTCOMES

Acquiring knowledge on the characteristic features of soft materials, the forces acting in these systems, the physical models which describe their behavior.

Exam description

Oral exam

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 it 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 understanding of the course topics and the student's ability to discern the validity limits of the models used.
