ANALYTICAL CHEMISTRY OF MATERIALS
Basic analytical chemistry and instrumental; knowledge about the structure of matter at the atomic and molecular level; spectroscopy of knowledge.
Written test on theory and solution of a real problem taken from the scientific literature.
The course's main objective is to provide students with the information needed to plan and deal with the analysis of materials, from the point of view of the characterization and chemical composition. The presented case studies, the result of multidisciplinary approach of "problem solving," are examples of how to implement these findings in order to develop personal understanding and skills in solving real problems.
The course will offer an overview of the main analytical techniques used in the analysis and characterization of materials.
