It is highly recommended that in order to study this subject, the students have passed “Quimica dels Elements”, “Química Orgànica” and “Laboratori de Microscòpies i Tècniques de Caracterització de Materials” from the 2nd year of the degree of Nanoscience and Nanotechnology, as many concepts of the 2nd year subjects will be used in the subject Synthesis and Structure of Crystalline and Amorphous Materials without previous explanation.
Synthesis and Structure of Crystalline and Amorphous Materials aims to provide a basic knowledge of materials and nanomaterials from their synthesis, structure and properties (mainly mechanical and chemical) point of view. Its content is based on aspects previously presented in subjects of the second year of the degree. In the part corresponding to the structure of the materials, it is based on the contents of the Chemistry of the Elements and the Microscopy Laboratory and Materials Characterization subjects, while the part of the polymeric materials is based on the contents of Organic Chemistry subject. This is a subject of Material Science in which an emphasis is placed on the structural and synthetic part, which is why Chemistry Bases subject for Nanoscience and Nanotechnology is in the field. Synthesis and Structure of Crystalline and Amorphous Materials is followed by a Solid State course where the Material Science topic is concentrated in its physical properties.
In a unified way the subject provides knowledge about the structure of crystalline materials, from the perfect crystals (reticular theory and crystalline lattices, infinite symmetry and X-ray diffraction) and following by real crystals (crystalline defects ). The study of crystalline materials is then completed with a presentation of the basics of the mechanical properties of the solids, of the phase transformation of metals and the most important ceramic structures. The synthesis of materials and nanomaterials is explained in two different topics where the different synthetic methodologies are exposed. The subject finishes with the study of the most important characteristics of polymeric materials. The subject consists of theory classes, exercises solving classes, classroom practices and laboratory practices.

Methodology:
The student will carry out three types of activities: directed, autonomous and supervised.
1.- Guided activities: Attendance is compulsory and carried out in the presence of a teacher.
1. Theoretical classes: The teacher exposes the contents of the subject and answer to the possible doubts that the student has.
2. Solving of problems classes: The knowledge acquired in the master classes and in the autonomous activities of the student, mainly through the study, are applied to the resolution of problems and exercises related to the contents of the subject.
3. Classroom practices / Laboratory practices: By carrying out of practical work related to the contents of the subject (work with PC programs and synthesis work in the laboratory).
2.- Autonomous activities: With these activities, the student alone, or in group, must achieve the competencies of the subject. Within these activities, we have studying, problems resolution, documents writing, texts reading and bibliographic research.
3.- Supervised activities: The student may ask the teachers of the subject supported tutorials for the assimilation of the subjects exposed in theory and problem solving classes, and for the solving of follow-up work.
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.

Evaluation
Assessment of the subject:
The subject will be evaluated continuously and will consist of the following evaluation activities:
Theoretical part
Represents 70% of the final mark. The student can chose for two ways of evaluating this part:
1) The continuous evaluation in which 2 mid-term tests will be carried out, and
2) The final evaluation where a final test will be carried out.
Continous evaluation:
First mid-term text: The contents of chapters 1 to 5 will be evaluated (35% of the final grade)
Part Two: The contents of chapters 6 to 10 will be evaluated (35% of the final grade)
If these tests are successfully passed with an average grade higher than 5.0 (provided that the mark of one of the partials is not less than 4), the final test will not be required.
If the average is less than 5, or any of the mid-term marks is less than 4, the student must pass the second-chance recovery test to pass the subject.
Final test:
The students will do a final test that will be divided into two exams corresponding to each part of the subject. Each exam will have a weight of 35% of the overall grade. Students may attend one or both parts of the final exam. To pass the subject, the average mark of the two parts (mid-term or final exam) must be equal to or greater than 5.0 (each part mark must be greater than 4).
Delivered exercises:
It will represent 15% of the final mark.
First mid-term exam: Students will have to resolve autonomously problems related to the contents of the subject that will be delivered in class.
Second mid-term exam: Class attendance is mandatory. Therefore, when the teacher considers it appropriate, and without prior notice, it will be able to collect exercises of the continuous work: problems solved in class or at home, tests written in class, or online questionnaires. In the case of justified absence in the day when the exercise is delivered, this exercise will not be considered in the calculation of the final mark. The justification will require the presentation of medical justification (it is not valid overlapping with other subjects, trips, work ...).
Classroom practices and laboratory practices:
They represent 15% of the final mark. The mark will be the average between the evaluation of the work done by the student in the classroom practices (50%) and in the laboratory practices (50%).
Attendance at laboratory practical sessions is mandatory
Improve mark in the final exam
The students who have passed the subject by mid-term exams but wish to improve the mark of one or both partial exams, they may attend the final exam under the following conditions:
1) If the student improves the mark, the best mark will be used.
2) If the student does not improve the mark, the average of the two marks will be made.
Unique assessment
In the case of students who take the unique assessment:
The grade will be = Exam grade (70%) + Evidence grade (15%) + Practices grade (15%)
If the final grade does not reach 5 and/or the exam grade does not reach 4, the student has another opportunity to pass the subject by means of the recovery exam, which will coincide with the recovery exam of continuous assessment students. The grade of the recovery exam replaces the grade of the previous exam only, not the evidences or practical works.
Others
Any copy action or ethically reprehensible actions in the assessment activities will suppose a zero mark in the subject, regardless of other disciplinary implications.
