PRINCIPI DI CHIMICA DEI MATERIALI

The course aims to deepen the knowledge and basic methodologies for the study and analysis of the main characteristics of innovative materials used in agriculture, in the chemical-pharmaceutical and bio-medical fields, with particular regard to the applications of biomaterials. for prosthetic implants and / or tissue growth for a better quality of life. Furthermore, the knowledge and skills useful for designing the chemical-physical properties of these materials are part of the objectives of the course, starting from the knowledge of the atomic and molecular structures that compose them.
