Objectives

This course is divided into two parts. The first part studies chemical equilibria and mechanisms governing the chemical transformations in terms of atomic and molecular structure. The systematic analysis of chemical reactivity is restricted to a few specific classes of chemical compounds and transformations of general interest and technological potential. Fundamental notions regarding the structure of matter and the basic principles governing the physico-chemical transformation processes (phase transitions, chemical reactions, etc.) are required.
The second part studies the most fundamental issues concerning Materials Science, in particular for building materials. Ceramics, metals and natural materials are considered focusing on their microstructural and macrostructural properties. The relationships between structure, processing and properties of materials will be illustrated with examples of both idealized and technological materials. Numerical exercises illustrate the main points of the lesson course.
Knowledge and understanding. At the end of this course, the student will achieve a sufficient knowledge of chemistry and materials science and of aspects which control chemical and physical phenomena of different materials.
Applying knowledge and understanding. The student will develop skills in the use of instruments relating to chemistry and materials science, which will allow him to understand the relation between structure and properties.
Making judgements. The student will develop self-evaluation capacity regarding chemistry and engineering materials, models and limits of knowledge.
Communication skills. Students will acquire basic and essential knowledge useful for his professional education for future practice as architects. chemistry and materials science studies will allow to make appropriate design choices.

Verification of learning

The evaluation will be performed in two different steps: chemistry and materials science.
Chemistry: a written part at the end of the course (or two intermediate tests during the course) and oral part.

Materials science: a written part at the end of the course (or two intermediate tests during the course) and oral part.

Final evaluation will take into account the results obtained by first and second part.

Part A- Chemistry

Written part will highlight the acquired knowledge by students on:
- the matter, its structure, its transformations and the principles which govern them;
- the elements and their chemical properties;
- the chemical bond, the secondary interactions and the relationship between the structure of a substance and its properties;
- chemical equilibrium;
- the principles of electrochemistry.

Oral part will allow to confirm or verify the knowledge level.


Part B- Engineering Materials

Written part will highlight the acquired knowledge by students on:
- materials structure;
- materials properties;
- formation process of materials;
- applications;
- perspective and future of materials science.

Oral part will allow to confirm or verify the knowledge level.
