Prerequisites
To have studied and passed the 3rd year course "Material Science"
Objectives and Contextualisation
"Solid State Chemistry" aims to expand the knowledge acquired with the obligatory subject of the third year "Material Science" by introducing significant concepts such as methods of preparation of materials and the physical properties of materials. Thus, at the beginning, the basic aspects of the synthesis of solid materials will be described, following with the study of their electrical, magnetic and optical properties. These properties will be related to their structural characteristics.

Methodology
The subject is given in the form of lectures and classroom practices. In addition, the students will have to do a bibliographical work and solve the questions posed by the teacher.
1) Lectures
Through the presentations of the teacher 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 bibliography recommended The lectures will be open to the participation of the students, who will be able to ask the professor the questions and clarifications they need. The teacher can assign specific exercises or questions to the students to solve them (at home or in the classroom) and discuss them in the classroom. The presentations of the bibliographical works of the students will also be done in these classes and the participation of all the students will be invoked in the sessions of questions and discussions regarding the works.
2) Bibliographical work.
Students must prepare a bibliographical work on a topic proposed by the teacher and they will have to defend it in public. They will also have to solve the exercises or questions raised by the teacher at home or in the classroom.
The objective of activity 2) is to work the subject autonomously and / or in group, deepening in specific subjects and solving issues raised by the teacher. The aim is to stimulate the participation of the students in the discussion of the subjects and in the approach of alternatives to solve certain problems.

Assessment
Assessment of the subject:
Class attendance is mandatory. Non-justified absences of up to 15% of the presential activities will be accepted and attendance at the presentation sessions of the works is required for all students. Failure to comply with this standard of assistance will make the student non-evaluable.
Exams
For evaluation purposes, the subject can be considered divided into two parts. During the semester there will be two midterms examinations, one from each part (ExP1 and ExP2), and a final makeup exam (ExF), all with a note between 0 and 10.
Bibliographic work and follow-up work
At the beginning of the course, a bibliographical work will be assigned to each student. This work will be done throughout the semester. The characteristics and the presentation of the work will be specified by the teacher at the time of the assignment. In addition, the teacher can assign other follow-up assignments (individual or group exercises) during the course.
The assessment of the bibliographic work and the follow-up work will give a score between 0 and 10 for each student (Treb)
Qualifications:
There will be two midterms whose notes will be ExP1 and ExP2.
To pass the course subject, the following three conditions must be met:
1) The final grade of the subject NF = [0.70 x (ExP1 + ExP2) / 2] + (0.30 x Treb) must be ≥ 5
2) ExP1 and ExP2 must be ≥ 4
3) Treb must be ≥ 4
To pass the subject by midterms, the following two conditions must be met:
1) The final grade of the subject (NF) must be 5
2) To be able to make the average, ExP1, ExP2 and Treb must be greater than or equal to 4
If the previous requirement is not fulfilled, the student must submit to the global makeup exam (ExF), where one or both midterms can be recovered.
The attendance to the ExP1 and ExP2 as well as the accomplishment of the bibliographical work is compulsory. Otherwise the student will be considered as non-evaluable.
The NF will be calculated in the manner explained above but replacing the values of ExP1 and ExP2 for those obtained in the ExF and will have to be greater than or equal to 5 to pass the subject.
The students who pass the course by midterms but want to improve their qualification, can go to the ExF but they will have to do it complete; that is, the two parts corresponding to each midterm. The final grade will be that obtained in the ExF.
