Chemistry and Materials Science Carlos Alemán Universitat Politècnica de Catalunya Universitat Politécnica de Catalunya - Spain Carlos Alemán Chemistry and Materials Science Materials science is an applied science concerned with the relationship between the structure and properties of materials. Chemistry provides information about the structure and composition of materials as well as the processes to apply and synthesize them. Chemists play a predominant role in materials science.
