Overall objectives:

1 - The main objectives of this course include: i) Properly identify the principles of operation and layout of nanomaterials characterization systems and instruments, identifying the state of the art of the different target study techniques, namely spectroscopic - IR, Raman, UV-Vis, NMR, and chromatographic - LC-MS and MALDI-TOFMS, their potential use and application limits; - Página 42 de 46 ii) Identify complementarity relationships between the characterization techniques; - Analyze and justify the characterization techniques chosen for a given nanomaterial; iii) Draw conclusions on the techniques and adequately support the data analytically using error bars and demonstrating the statistical validity of the conclusions. iv) The laboratory work led to the deepening of the domain of safety procedures and sufficient understanding of the complexity of the techniques will be carried out within the scope of UC Laboratories in Nanochemistry and Nanomaterials II.

Syllabus:

0 - The program consists of:
1 - Introduction to Spectroscopy Applied to Nanomaterials
1.1 - Optical Spectroscopy - Infrared (IR) and Raman, Ultraviolet-visible, fluorescence, chirality, optical rotation, circular dichroism (CD);
1.2 - Liquid and solid-state nuclear magnetic resonance (NMR) and electronic paramagnetic resonance (EPR);
2 - Mass spectrometry - main configurations and techniques, types of ionization (atmospheric pressure chemical ionization (APCI), electrospray ionization (ESI), laser assisted matrix desorption ionization (MALDI), induction coupled plasma ( ICP)), traps (eg quadrupole, ion trap, orbitrap) and detectors;
3 - Liquid (e.g. HPLC including molecular exclusion (SEC)) and gas (GC) chromatography techniques. Hyphenated GC and HPLC techniques to mass spectrometry - main configurations and techniques;
4 - Rheological techniques (e.g. intrinsic viscosity, differential scanning calorimetry (DSC))

Evaluation Methodology:
The theoretical classes are used for the contextual exposition of the major topics stated in the program. The syllabus contents are exposed and illustrated with examples, and whenever appropriate, the discussion with students on the subjects under study and problem solving will be privileged. The evaluation of the discipline of Analysis and Characterization of Nanomaterials II will be continuous, being subdivided into two written tests, during the academic period corresponding to each 40% for the final evaluation (80% of the final grade) and for the presentation and discussion of one. research work on the state of the art of nanomaterials characterization techniques based on scientific articles, and which will support the PL classes to be developed at UC Laboratories on Nanochemistry and Nanomaterials II The final evaluation will be: AF = 80% written tests + 20% article discussion Passing the course requires a grade ≥9.5 points in each of the written tests to be performed.
