B1779 - MICROSCOPIA CON LABORATORIO

Learning outcomes

Al termine del corso lo studente consoce le basi delle principali tecniche di caraterizzazione di proprietà meccaniche, ottiche, elettriche e strutturali per le principali classi di materiali (metallici, polimerici, ceramici). Lo studente acquisisce anche conoscenze nel settore della caratterizzazione microscopica dei materiali. Lo studente ottiene competenze di base per condurre esperimenti di laboratorio e ha imparato ad analizzare, interpretare e presentare risultati sperimentali relativi a proprietà e struttura di materiali.

Course contents

Measurement of mechanical, optical and electrical properties.
Revelation of the microstructure of materials via X-ray diffraction and light or electron microscopy techniques.
Scanning probe microscopy
Main characterization techniques for different classes of materials (metallic, ceramic and polymeric)
Laboratory management and maintenance techniques

Teaching methods

Five laboratory tests will be carried out during which students, in groups of 2 or at most 3 students, conduct material characterization experiments.

- Observation of a metal alloy via optical microscopy
- Characterization of the dielectric properties of polymers
- Bandgap measurement of semiconductor materials
- Determination of the elastic modulus of metals
- Determination of the lattice constant of a crystalline material

For each experiment, a written report is required according to a standard format, which must be submitted by each student
Laboratory tests are introduced in a series of classical lessons with traditional methodology. Group work exercises lead to learning to apply the concepts of material characterization.

Assessment methods

The exam of the integrated Materials Characterization course will focus on the topics covered in the "Microscopy with Laboratory" and "Materials Spectroscopy" modules.

As regards the topics covered in the "Microscopy with Laboratory" module, the exam includes laboratory tests and an oral exam at the end of the course. For the laboratory tests, the student must write a report, following a template provided by the teacher, in which the methodology, experimental results and their analysis are reported. The reports must be delivered in PDF format at the end of the tests. The oral exam at the end of the course consists of three questions on topics covered during the course. The final score is assessed based on the knowledge of the course topics in the exam and the evaluation of the laboratory reports.

The final grade of the integrated course will be calculated via the arithmetic average of the grades obtained in the two modules. To pass the integrated course it is necessary to pass 18/30 in both modules.

Teaching tools

Material physics laboratory with instrumentation for the characterization of materials.
