Crystallography and Laboratory
A.Y. 2018/2019
Learning objectives
Knowledge and understanding, built also on the basis-level three-year degree, to achieve the ability to describe crystalline matter and undertake its study by diffraction techniques, enabling to identify, describe and perform research on the crystalline state of geological materials.
Applying knowledge and understanding The course provides the ability to properly recognize and describe periodicity and symmetry and to identify it through diffraction analysis, thus providing support to Earth Sciences disciplines, that require knowledge of the properties of the crystalline nature of geomaterials.

Expected learning outcomes
Making judgements The course delivers ability to face crystallographic problems through analysis and management of the complexity of processes underlying radiation-matter interaction. The student will be proficient on understanding and critically analysing the experimental results obtained through diffraction experiments, as well as the assessment of accuracy/reliability of experimental data.
Communication skills The course will deliver the knowledge of international terminology, including symbolism and English jargon, enabling universal communication of problems and phenomena related to the symmetry of materials and its study by diffraction techniques. The student will be qualified to propagate the crystallographic knowledge outreach in a wide range of contexts.
Learning skills The student will be able to outspread the acquired knowledge allowing him to cope independently in crystallographic research, both in geological contexts and with synthetic inorganic materials (mineralogical proxies).
