OVERVIEW

Aim of this class is to provide the basic knowledge of in-line control techniques based on spectroscopical methods for the assessment of quality both for goods and for industrial processes.

AIMS AND CONTENT

LEARNING OUTCOMES

Aim of the class is to provide fundamental knowledge on the use of non-destructive optical methods for the investigation of polymer properties, catalysis, and of industrial processes. Remote detection techniques in the UV-Vis, NIR and MIR spectral ranges will be described.

AIMS AND LEARNING OUTCOMES

Fundamentals of UV-Vis-NIR-MIR and raman spectroscopies

Fundamentals on the use non destructive optical methods (light source, spectrometers, optical fibers, filters,monochromator and gratings) for the investigation of polymer properties, catalysis, and chemical processes both on lab and industrial scale.

In-line optical detection techniques in the UV-Vis, NIR and MIR spectral ranges.

PREREQUISITES

Basic knowledge on Chemical Sciences and spectroscopy

TEACHING METHODS

Class lecture, demo-software, lab work. Powerpoint presentation of teacher and lab notes available from the University Web Site (AulaWEB). Lab simple experiments of spectroscopy on quality of materials

SYLLABUS/CONTENT

 

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.

EXAMS

EXAM DESCRIPTION

Oral exam held by two professors, one of them being D. Comoretto.

The duration of the exam is no shorter than 30 minutes.

The student discusses an original power-point presentation or written relation on an item related to the class or the laboratory activities.

The student selects 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 has to be suitable for understanding by students of the same level.

The student must show to understand main physical/chemical/technological fundamentals related to the topics and to report the results with a suitable technical vocabulary answering questions in a critical and professional way (up to 15/30).

Moreover, He/She must show to have understood experimental features of the techniques described (up to 10/30).

Finally, the clarity of presentation will be also evaluated (up to 5/30).

ASSESSMENT METHODS

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 the teacher for additional explanations before 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 students with specific unparities, the assessment method will comply with the UNIGE rules summarized in https://unige.it/disabilita-dsa.
