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.

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.
Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.
Assessment

|---|---|---|---|---|
| Bibliographic work and exercises | 30 | 3 | 0.12 | 1, 8, 3, 16, 17, 4, 5, 6, 9, 10, 7, 13, 2, 18, 11, 12, 14, 15, 20, 19 |
| Written exams | 70 | 4 | 0.16 | 1, 8, 16, 17, 4, 5, 6, 7, 2, 18, 12, 14 |
Subject evaluation:
Class attendance is mandatory. Unjustified absences of a maximum of 15% of the supervised activities will be admitted and attendance at the presentation sessions is mandatory for all students. Failure to comply with this attendance policy will result in the student being unassessed.
Exams
For assessment purposes, the subject can be considered divided into two parts. Two will be held throughout the semester
partial exams, one for each part (ExP1 and ExP2), and a final recovery exam (ExF), all with a grade between
0 and 10.
Bibliographic work and follow-up work
At the beginning of the course, each student will be assigned to carry out a bibliographic work that will be carried out throughout the semester. The characteristics and presentation of the work will be specified by the teacher at the time of assignment. In addition, teachers can assign other follow-up assignments (individual or group exercises) during the course.
The evaluation of the bibliographic work and of the follow-up works will give rise to a note between 0 and 10 for each student (Treb)
Qualifications:
There will be two partial exams whose grades will be ExP1 and ExP2.
To pass the subject per course (by part) the following conditions must be met:
1) Attendance at ExP1 and ExP2 as well as the completion of bibliographic work is mandatory; otherwise the student will be considered non-assessable.
2) ExP1 and laExP2 must be ≥ 4
3) The Treb grade must be ≥ 4
4) The final grade of the subject NF = [0.70 x (ExP1 + ExP2) / 2] + (0.30 x Treb) must be ≥ 5
In the event that the above requirement is not met, the student must do the recovery exam (ExRx), where he / she will be able to retake one or both of the exams (ExR1 and ExR2).
The NF will be calculated as explained above, but replacing the values of ExP1and ExP2 with those obtained in ExR1 and / or ExR2, which must also be equal to or greater than 4. In any case, NF must be greater than or equal to 5 to pass the subject.
Students who pass the course but want to improve their grade, may take the global exam but must complete it; that is, (ExR1 + ExR2) and their final grade will be exclusively the sum obtained in these exams.
Single Evaluation
Students who have taken the single evaluation modality will have to take a final test which will consist of an examination of the entire syllabus to be carried out on the day when the students of the continuous evaluation take the second part exam. The exam will consist of two parts ExP1 and ExP2 and the grade of ExP1 and ExP2 must be ≥ 4 in order to pass the subject. On the same day, they must deliver a PowerPoint presentation of the topic assigned at the beginning of the cours at the Virtual Campus, in the task enabled for the purpose. The presentation must contain the text of the presentation associated with the images. In order to pass the subject, the grade of the work must be equal to or higher than 4. If recovery is required, it will be done on the same date and under the same conditions as students evaluated continuously.
