Metodi di valutazione

Modalita' di verifica dell'apprendimento: 

The exam can be taken at the choice of the student in Italian or English and consists of two tests.

The first test consists of an oral presentation, in front of the whole group of students, of a selected topic among those proposed concerning the use of nanotechnologies in the field of sustainable energy production, new innovative materials, telecommunications systems and quantum computing, sensorial and environmental applications, etc.

The second test consists of an oral presentation, with the same characteristics as the previous one, on topics related to nanoparticles for diagnostic and therapeutic use, biomaterials for tissue engineering applications, biomaterials for prothesis and biomaterials for the development of advanced in vitro cell models.

Individual oral presentations are the subject of open discussion, with questions and contradictions, and the level of knowledge acquired, the autonomy of analysis and judgment, the student's presentation skills, the ability to identify particularly promising advances in a given nanotechnology sector will be checked.

The final grade, expressed in thirtieths with possible “laude”, is the average of the grades two tests.
