It is recommended that for the subject "Materials Science", all first year subjects and the "Chemistry of the Elements" and the "Structure and Reactivity of Organic Compounds" of the second year of the Chemistry degree have been passed.
"Material Science" is a compulsory subject of the Chemistry degree third year. It includes knowledge of a general and transversal nature, as it combines scientific areas such as applied physics, chemistry and geology, along with areas of engineering, such as selection, testing and behavior of materials.
Its contents are based on the competences achieved in the subjects of the first year and those of "Chemistry of the Elements", "Structure and Reactivity of Organic Compounds" and "Chemistry of Coordination and Organometallic". With this subject, the student will complete a basic training cycle in the field of the structure, properties and applications of the different solids, classified according to their atomic structure and chemical bond.
Its objective is to establish the relationship existing between the structure of matter at the atomic or molecular level and its macroscopic properties. This allows to explain and predict the characteristics and behaviors of macroscopic and nanomaterial dimensions. Within this context, mechanical properties are highlighted, which once linked to the defects and the multifacic nature of the solids, allow the understanding of the mechanical behavior of materials as important as metals and alloys, ceramics and polymers. This knowledge is basic to establish methodologies for the selection of the most suitable material for each application based on the specific requirements demanded. In the case of practical classes, the objective is to start the student in the techniques of preparation and characterization of solids, which have characteristic features different from those used in molecular chemistry.
1.- Study of the perfect crystal. Crystalline and non-crystalline materials Structure of crystalline solids.
2.- The real crystal. Imperfections in solids and microscopic observation. Uni, bi and three-dimensional defects. Diffusion in solids.
3.- Mechanical properties of solids. Deformation and hardness. Mechanisms of hardening. Recovery, recrystallization and growth of grain.
4.- Metallic materials. Diagrams of phase equilibrium and phase transformations. Thermal treatments of metals and alloys.
5.- Ceramic materials. Structure and mechanical properties of ceramics. Applications, forming and processing of ceramics.
6.- Polymeric materials. Polymeric compounds; Synthesis, structure and mechanical and thermomechanical characteristics. Applications and forming of polymers.
The subject consists of two types of supervised activities; the lectures and the problems classes, that are given in a concerted manner and are distributed throughout the course in an approximate 3 to 1 ratio.
Lectures
Through the teacher's explanations the student must acquire the own knowledge of this subject and complement them with the study of each subject treated with the help of the material that the professor provides through the Virtual Campus and the Recommended bibliography. The lectures will be open to the students participation, who will be able to raise to the professor any questions and clarifications needed.
Problems classes
The objective of this supervised activity is to solve problems and questions that have been previously raised to the students through the Virtual Campus and that have had to be resolved previously, in group or in person. Due to the smaller number of students in this type of classes, it is intended to stimulate participation in the discussion of the alternatives to solve the problems, taking advantage of it to consolidate the knowledge acquired in theory classes and through the personal study.

Exams
For evaluation purposes, the subject can be considered divided into two parts.
Throughout the semester two midterm exams will be carried out, one from each part (ExP1 and ExP2), and a global second-chance exam (ExG), all of them with a grade between 0 and 10.
Follow-up work
Throughout the semester a certain number of tests of student follow-up will be collected (for example, problems solved individually or in groups, short classroom tests, reading of scientific texts, questionnaires, online activities, etc.). For each part of the subject, each student will have a minimum of two grades of these follow-up tests. Each student will obtain, therefore, two follow-up notes (S1 and S2), which will be the averages of the grades obtained in the follow-up tests of each part of the subject.
Ratings:
Each part of the subject will have a grade (Not1 and Not2) that will be:
Not1 = 0.85 x ExP1 + 0.15 x S1
Not2 = 0.85 x ExP2 + 0.15 x S2
The final grade (NF) will be obtained in the following way:
NF = (Not1 + Not2) / 2
In case the distribution of teaching hours destined to each part was very unbalanced, a different weighting will be used other that the 50% for Not1 and Not2 in the calculation of NF
To pass the subject, the following two conditions must be met:
1) The final grade for the subject (NF) must be ≥ 5.0
2) To be able to do media, ExP1 and ExP2 must be ≥ 4.0
In case the above requirements are not met, the student must go to the second-chance exam, where he / she will be able to recover one or both parts, since the subjects of each part will be separated and identified as it (NR1 and NR2). The NF will be calculated by replacing the Not1 and / or Not2 values obtained in the NR1 and / or NR2 second chance exam.In case that the grade obtained in one or both NRX notes (x = 1, 2) is less than 4, the final grade (NF) will be obtained by the average of NRX, but it never will exceed 4.
In order to pass the subject in the second chance exam, the following two conditions must be met:
1) The final grade of the subject must be ≥ 5.0
2) To be able to do media, Not1 and Not2 (NR1 and NR2 in case of recovery) must be ≥ 4.0
Students who pass the course by midterm evaluation but want to improve their qualification, they have the option to do the second chance exam but must do it fulfilled; that is, the two subtests corresponding to each part. In this case the final grade (NF) will be the average of the grades obtained in the second chance examinations.
In order to be considered as assessable, it is necessary to:
- Attend at least 80% of the classes
- Deliver complete, with all the exercises solved, at least 75% of the requested evidences
- Present at the two midterm exams
If one of the three previous requirements is not met, the student will be considered not assessable.
