Learning Objectives
Knowledge acquired:
Methods for nanoparticles synthesis. Physico chemical characterization of soft matter systems used in restoration. Thermodynamics of degradation processes of natural and synthetic materials., Spettrofotometry analysis: theoretical principles, techniques description, and application in the field of cultural heritage materials.
Competence acquired Competence in setting up of restoration protocol and critical analysis of technologies to be used in restoration. Competence in experimental analysis of materials and interpretation of data. Competence in diagnostics and interpretation of degradation processes; both in setting up of experiments and in description of reactions and mechanisms involved in material weathering.
Skills acquired (at the end of the course):
Skills in: (i) application of physicochemical techniques about which students have acquired knowledge of their theoretical principles and resolution of simple problems in diagnostics in the field of cultural heritage, (ii) correct interpretation of all the experimental data, (iii) working in a chemical laboratory, (iv) working in team, (v) presentation of the results of the experiment, (vi) presentation of the knowledge and competences acquired.
