Objectives
THE COURSE AIMS TO PROVIDE THEORETICAL AND PRACTICAL KNOWLEDGE OF THE STRUCTURAL CHARACTERISTICS OF MATERIALS AND THEIR PHYSICAL PROPERTIES.
IN DETAIL, IN PART 1 THE STRUCTURES OF METALS, ALLOYS, CERAMIC MATERIALS, POLYMERIC MATERIALS AND COMPOSITE MATERIALS WILL BE DESCRIBED. TOPICS SUCH AS: DISORDER IN SOLID PHASES, POINT DEFECTS AND DISLOCATIONS WILL BE ILLUSTRATED; PHASE EQUILIBRIA, PHASE DIAGRAMS; SPEED OF TRANSITIONS; MICROSTRUCTURES; DEFORMATION AND FRACTURE; REINFORCEMENT, TOUGHENING; CORROSION REACTIONS; CORROSION CONTROL; FATIGUE.
THE PHYSICAL PROPERTIES OF MATERIALS WILL BE DESCRIBED AND KNOWLEDGE OF ADVANCED MATERIALS SUCH AS SMART MATERIALS AND NANOMATERIALS WILL BE PROVIDED.
THE MAIN MATERIALS CHARACTERIZATION TECHNIQUES WILL BE DESCRIBED AND EXERCISES WILL BE CARRIED OUT ON TOPICS SUCH AS PHASE DIAGRAMS OF ALLOYS AND CERAMIC MATERIALS.
FINALLY, THE COURSE WILL PROVIDE THEORETICAL AND PRACTICAL KNOWLEDGE ON PATENT RESEARCH.
A FURTHER OBJECTIVE OF THE COURSE IS TO PROVIDE THEORETICAL AND PRACTICAL KNOWLEDGE OF THE MAIN POLYMERIZATION TECHNIQUES APPLIED TO THE SYNTHESIS OF TRADITIONAL POLYMERS OF INDUSTRIAL INTEREST AND INNOVATIVE ONES IN THE FIELD OF BIODEGRADABLE POLYMERS.
IN DETAIL, IN PART 2, THE ORGANIC CHEMISTRY AND PHYSICAL CHEMISTRY OF THE REACTIONS THROUGH WHICH MACROMOLECULES ARE SYNTHESIZED WILL BE DESCRIBED. POLYMERIZATION REACTIONS ARE CHARACTERIZED IN THEIR KINETIC AND THERMODYNAMIC ASPECTS. THEIR PURPOSE AND USEFULNESS FOR THE SYNTHESIS OF DIFFERENT TYPES OF POLYMERIC STRUCTURES AND THE PROCESS CONDITIONS USED FOR THEIR REALIZATION ARE DISCUSSED. THE INDUSTRIAL SYNTHESIS OF THE MAIN POLYMERIC MATERIALS AND NEW POLYMERIC MATERIALS THAT ARE BIODEGRADABLE AND/OR OBTAINED FROM RENEWABLE SOURCES WILL BE DESCRIBED. THE PROBLEM OF RECOVERY AND RECYCLING OF PLASTIC MATERIALS WILL BE ADDRESSED, FIRST IN GENERAL AND THEN IN DETAIL FOR EACH POLYMERIC MATERIAL STUDIED.



THE STUDENT WILL KNOW AND HAVE DEVELOPED AN UNDERSTANDING OF THE STRUCTURAL CHARACTERISTICS OF METALS, ALLOYS, CERAMIC MATERIALS, POLYMERIC MATERIALS, COMPOSITES AS WELL AS THE PHYSICAL PROPERTIES OF THESE MATERIALS, UNDERSTANDING THE CLOSE RELATIONSHIP BETWEEN THE PROPERTIES AND STRUCTURE OF THE MATERIALS THEMSELVES. IN THE CASE OF POLYMERIC MATERIALS, THE STUDENT WILL HAVE DEVELOPED AN UNDERSTANDING OF HOW SYNTHESIS PROCESSES AND TECHNIQUES ARE CRUCIAL FOR OBTAINING A MATERIAL WITH DEFINED PROPERTIES.
THE STUDENT WILL HAVE DEVELOPED AN UNDERSTANDING OF THE RELATIONSHIP BETWEEN THE CHEMICAL NATURE OF THE MATERIAL, THE CHEMICAL-PHYSICAL AND MECHANICAL PROPERTIES AND HOW TO ADDRESS THE PROBLEM OF RECOVERY AND RECYCLING.
THE STUDENT WILL HAVE DEVELOPED AN UNDERSTANDING OF THE MOST COMMONLY USED PHASE DIAGRAMS OF ALLOYS AND CERAMIC MATERIALS
THE STUDENT WILL HAVE LEARNED THE BASIC KNOWLEDGE FOR PATENT SEARCH
THE STUDENT WILL BE ABLE TO:
- DESCRIBE THE STRUCTURAL CHARACTERISTICS OF THE DIFFERENT TYPES OF MATERIALS - INDICATE THE PROPERTIES OF THE DIFFERENT TYPES OF MATERIALS
-INDICATE THE MOST SUITABLE TECHNIQUES FOR THE CHARACTERIZATION OF MATERIALS
- IDENTIFY THE SYNTHESIS TECHNIQUE TO OBTAIN THE DESIRED POLYMER
- CONNECT THE CHOICE OF POLYMERIZATION TECHNIQUE WITH THE PROCESS CONDITIONS REQUIRED ALSO IN THE INDUSTRIAL SECTOR
-CONNECT THE STRUCTURE OF THE POLYMER TO THE RECOVERY AND RECYCLING TECHNIQUES OF THE ASSOCIATED PLASTIC MATERIAL
THE STUDENT, ON THE BASIS OF THE KNOWLEDGE ACQUIRED IN THE FIELD OF MATERIALS AND THEIR PROPERTIES, WILL BE ABLE TO DISCRIMINATE BETWEEN THEM AND IDENTIFY THE MOST SUITABLE MATERIAL TO USE TO CREATE AN ARTEFACT CHARACTERIZED BY A SPECIFIC REQUIRED PROPERTY.
THE STUDENT WILL BE ABLE TO COMMUNICATE THE KNOWLEDGE ACQUIRED DURING THE COURSE, BOTH ORALLY AND THROUGH TEXTS OR VIRTUAL TOOLS, RESEARCH RESULTS OR OWN ELABORATIONS USING APPROPRIATE SCIENTIFIC TERMINOLOGY.
THE STUDENT WILL BE ABLE TO:
- UNDERSTAND AND INTERPRET BIBLIOGRAPHIC TEXTS ON DIFFERENT TYPES OF MATERIALS
- UNDERSTAND AND INTERPRET PATENT LITERATURE
- PROCEED WITH THE CONTINUOUS UPDATING OF ONE'S KNOWLEDGE OF MATERIALS, USING TECHNICAL AND SCIENTIFIC LITERATURE
Prerequisites
NECESSARY KNOWLEDGE OF PHYSICS AND CHEMISTRY, AS WELL AS THOSE OF POLYMER CHEMISTRY
Contents
PART 1 :
STRUCTURAL CHARACTERISTICS OF MATERIALS AND RELATED PHYSICAL PROPERTIES. CRYSTALLINE STRUCTURES OF METALS, ALLOYS, CERAMIC MATERIALS, COMPOSITE MATERIALS AND POLYMER MATERIALS. (1 CFU - 8 HOURS + 1CFU-12 HOURS EXERCITATIONS).
IMPERFECTIONS PRESENT IN THE SOLIDS, PUNCTUAL DEFECTS AND DISLOCATIONS HIGHLIGHTING HOW THEIR PRESENCE ALTERES THE PROPERTIES OF THE MATERIALS THEMSELVES, FOR EXAMPLE INCREASING THEIR RESISTANCE. (0,5 CFU / 4 HOURS ).
MAIN TECHNIQUES FOR THE CHARACTERIZATION OF MATERIALS: TECHNIQUES FOR THE DETERMINATION OF THE CRYSTALLINE STRUCTURES OF SOLIDS AND THE MICROSCOPIC STRUCTURES AIMED AT THE DETERMINATION OF GRAIN SIZES (TEM, SEM). (0,5 CFU / 4 HOURS).
PHASE DIAGRAMS.TRANSFORMATION OF THE MICROSTRUCTURE AND THEN OF THE PROPERTIES OF THE MATERIALS (1 CFU - 8 HOURS +1 CFU - 12 HOURS EXERCITATIONS) .

Teaching Methods
THE COURSE IS ESSENTIALLY CONSTITUTED FROM FRONT LESSONS. VISITS TO MATERIAL CHARACTERIZATION LABORATORIES ARE ALSO PLANNED, DURING WHICH THE MAIN INSTRUMENTS USED IN THIS FIELD WILL BE DESCRIBED.
Verification of learning
THE ACHIEVEMENT OF THE TEACHING OBJECTIVES IS VERIFIED BY PASSING AN EXAM WITH A RATING OUT OF THIRTY. THE TEST IS CONSIDERED PASSED WITH A MINIMUM MARK OF 18/30.
THE EXAM INCLUDES TWO ORAL TESTS, ONE AT THE END OF EACH MODULE. BOTH SINGLE ORAL TESTS WILL LAST 30 MINUTES. THE STUDENT WILL HAVE TO ANSWER A SERIES OF QUESTIONS THAT COVER ABOUT 75% OF THE TOPICS COVERED IN THE RELEVANT MODULE. THE FINAL RATING IS CALCULATED AS THE AVERAGE OF THE SCORES OF THE TWO TEST
IN DETAIL, FOR THE FIRST MODULE THE EXAM TOPICS WILL BE THE STRUCTURAL CHARACTERISTICS AND PHYSICAL PROPERTIES OF MATERIALS, WHILE FOR THE SECOND MODULE TOPICS TAKEN FROM THE ENTIRE PROGRAM COMPLETED.
THE SCORE OF THE ORAL EXAM WILL DEPEND ON THE DEGREE OF IN-DEPTH, THE STUDENT'S ABILITY TO PRESENT THE TOPICS EXPLAINED IN THE CONTENTS SECTION EFFECTIVELY AND WITH RIGOROUS SCIENTIFIC LANGUAGE, AND THE MATURITY EXPRESSED BY THE STUDENT IN CRITICALLY DISCUSSING THE TOPICS ALSO BY PROPOSING CONNECTIONS WITH THE CONTENTS OF OTHER TEACHINGS.
THE STUDENT REACHES THE LEVEL OF EXCELLENCE IF THEY DEAL WITH UNUSUAL PROBLEMS (OR NOT EXPRESSLY ADDRESSED IN LESSONS) AMONG THOSE PROPOSED IN THE ORAL.
