The course highlights the analytical application of powder diffraction and thermal analysis in material chemistry and furnishes the basic notions of Mass Spectrometry and Nuclear Magnetic Resonance spectroscopy for the structural elucidation of organic compounds.
Expected learning outcomes
At the end of the course the student will be able to: -interpret thermal events in DSC and TGA analyses -interpret powder diffraction patterns, use the crystallographic databases and perform simple quantitative and qualitative analyses on polycrystalline mixtures. - interpret the result of a multivariate analysis - interpret spectra and to identify the structure of simple organic compounds from 1H and 13C NMR and MS spectra.
Principles of diffraction analysis, practice of diffraction analysis, qualitative and quantitative phase analysis, ICDD Powder diffractions files, NIST standard reference materials, microstructure characterization. Examples of industrial applications of powder diffraction in the field of pharmaceuticals and materials. Thermal analysis: principles. Thermogravimetry and differential scanning calorimetry. Principles of multivariate analysis.
Principles of Mass Spectrometry (MS), structural determination of organic compounds, applications of HPLC-MS. Fundamentals of 1H and 13C NMR spectroscopy. Chemical shift and spin coupling.

Assessment methods and Criteria
Verification of learning by written exam: the exam is organized in a written test with a maximum value of 30/30 (thirty). The test will be divided into two parts, one part will concern the program carried out on diffraction and one part will concern MS and NMR. Each part will consist of questions on theory and exercises and will award 15 (fifteen) points.
