Learning Objectives

Knowledge of the design, synthetic and characterization methods of inorganic materials. For this reason, a wide scenario of synthetic methods of polycrystalline and single crystals inorganic materials is presented to the students. A special focus is devoted to advanced methodologies for the functionalization of inorganic substrates and to their characterization techniques

Course Structure

This course is organized through lectures(5 CFU) and lab practice (2CFU) in order to give the oppurtunity to apply theoretical knowledge on practical simple cases.
