This class answer to the request for in-line control technique assessing the quality of products and processes. In particular, fiber optical spectroscopic techniques are demonstrated to be suitable for.
At the end of this course, the student will possess basic know-how to use non-destructive optical methods to probe properties of polymers, catalysis, and industrial processes.
Particular emphasis will be devoted to remote sensing techniques in the UV-Vis, NIR e MIR spectral range.
Basic knowledge of polymer properties and thermodynamics of industrial processes
Lectures delivered by Power Point presentations available to students on AulaWeb. Laboratory experiments in-line and off-line on MIR-NIR and UV-Vis spectroscopy to understand main properties of polymer materials.
Programme/Contents (synopsis):
The electromagnetic spectrum and fundamental quantities, basic optics (refraction, reflection, transmission, polarization, interference, diffraction, gratings, optical fibers). Fundamentals light-matter interaction (UV-Vis absorption, NIR, MIR, photoluminescence, Raman). Basic information obtained in different spectral ranges with particular emphasis for the comparison between MIR and NIR. Principles of common spectrometers in particular compact and transportable systems allowing collection and detection of signals by optical fibers. Use of the spectroscopic techniques (in particular those based on remote sensing) to probe the quality of industrial processes.
Lab: Examples of main sampling collection techniques (transmission, reflection, ATR, DRIFT, PAS, Raman) for on-line process control. Interpretation of spectroscopic data.

The student discusses an original power-point presentation or written relation on an item related to the course. The student select the item more suitable to his/her aptitudes/needs with the help of the teacher among those reported in the scientific literature and/or provided on aula-web (usually one or two papers). The presentation have to be suitable for understanding by students of the same level.
The student must show to have understood fundamentals related to the topics and to use the suitable technical vocabulary (up to 15/30). Moreover, he/she must show understanding of the investigation technique reported (up to 10/30). The quality of presentation/relation will be evaluated up to 5/30.
Goal of the exam is to verify the achievement of the class aims. If aims are not achieved, the student is invited to make a deeper study and to ask for additional explanation by the teacher bepore repeating the exam. In order to guarantee the correspondence between aims and exam topics, the detailed program is uploaded to AulaWeb and described at the beginning of the course.
For any further information, students are kindly invited to directly contact the teacher by email (davide.comoretto@unige.it), telephone (0103538736/8744) or visiting him in his office/lab.
