Prerequisites
Students should have taken and passed the 2nd year subjects "Chemistry of the Elements" and "Organic Chemistry", and have taken the 1st semester subject of the 3rd year "Supramolecular Chemistry and Molecular Recognition". Many concepts from these subjects will be used without prior explanation.
Objectives
The aim of this course is for students to acquire knowledge about the most common methods used for the synthesis of nanomaterials, which will allow them to interpret and propose processes for the preparation and functionalisation of these types of materials. In addition, the course will also provide knowledge about the structure and properties of nanomaterials.

Learning activities and methodology
| Title | Hours | ECTS | Learning outcomes |
|---|---|---|---|
| Theory lectures | 40 | 1.6 | CM25, CM26, KM44 |
| Tutoring | 4 | 0.16 | CM25, CM26, KM44 |
| Autonomous study | 76 | 3.04 | CM25, CM26, CM27, KM44 |
| Lab practices | 12 | 0.48 | CM27, SM37, SM40 |
Students will have to develop various types of activities throughout the subject:
a) Directed activities: In the classroom, theory lectures will be held on the contents of the subject. On the other hand, the students will also carry out practices in the chemistry laboratory consisting of the synthesis of nanomaterials.
b) Autonomous activities: Independently, students must study the contents of the subject, solve problems, prepare laboratory practices and write reports for these practices.
c) Supervised activities: The student may request support tutorials from the teaching staff of the course for the assimilation of the subject presented in the theory classes, and for the resolution of follow-up work.
Note: 15 minutes of a class will be reserved within the calendar established by the centre or by the degree for students to fill in the surveys for the evaluation of the teaching staff's performance and the evaluation of the subject or module.
Assessment
Continuous assessment activities
| Title | Weight | Hours | ECTS | Learning outcomes |
|---|---|---|---|---|
| Short exercises | 10% | 2 | 0.08 | CM25, CM26, CM27, KM44 |
| Written exams | 75% | 6 | 0.24 | CM25, CM26, KM44 |
| Lab reports | 15% | 10 | 0.4 | CM27, SM37, SM40 |
The evaluation can be carried out in two modalities:
A) Continuous evaluation
Written theory exams: Two midterm exams will be held throughout the course, one in the middle and the other at the end of the semester. Each of these exams will have a weight of 37.5% on the final grade.
- First midterm: The contents of Lessons 1 to 3 will be evaluated (37.5% of the final grade).
- Second midterm: The contents of Lessons 4 to 5 will be evaluated (37.5% of the final grade).
Exercises: Throughout the course, 4-6 exercises will be carried out in person in the classroom, whose average grade will contribute 10% to the final grade.
Laboratory practices: Laboratory practices will be evaluated by correcting reports, whose grade will be equivalent to 15% of the final grade of the subject.
The final grade will be obtained as: Final grade = Written exam grade (75%) + Evidence grade (10%) + Practice grade (15%).
In order to pass the subject, the grades obtained for each of these sections must meet the following conditions:
1) The grade of each of the written theory exams must be equal or higher than 4.0.
2) The average grade of the two written theory exams must be equal or higher than 5.0.
3) The weighted average grade for all the assessment activities of the subject must be equal or higher than 5.0.
4) Have attended the 3 sessions of laboratory practice.
Students who do not meet conditions 1 and/or 2 must take a retake exam at the end of the semester, which will be independent for each of the two parts of the course. The grade obtained in this retake exam will replace that of the corresponding previous written exams. In order to take the final exam, students must have participated in assessment activities throughout the course that are equivalent to 2/3 of the grade of the subject. Otherwise, the grade will be "Not assessed".
If after the retake exam, the student does not meet conditions 1 and/or 2, the maximum grade they can obtain will be 4.8.
B) One-step evaluation: Within a single activity at the end of the semester, the following activities will be carried out:
Written theory exam: A single theory exam will be carried out that will have a weight of 85% on the final grade. That final exam will be divided into two parts, each of which will be evaluated separately with a weight of 42.5%.
Laboratory practices: The report of the laboratory practices will be delivered, whose grade will be equivalent to 15% of the final grade of the subject.
The final grade will be obtained as: Final grade = Written exam grade (85%) + Practice grade (15%).
In order to pass the subject, the grades obtained for each of these sections must meet the following conditions:
1) The grade of each of the two independent parts of the written theory exam must be equal or higher than 4.0.
2) The grade of the written theory exam must be equal or higher than 5.0.
3) The weighted average grade for all the assessment activities of the subject must be equal or higher than 5.0.
4) Have attended the 3 sessions of laboratory practice.
Students who do not meet conditions 1 and/or 2 must take a retake exam later, which will be independent for each of the two parts of the course. The grade obtained in that retake exam will replace that of the parts of the previous written exam that were to be retaken. In order to take the retake exam, students must have previously participated in the activities of the single assessment. Otherwise, the grade will be "Not assessed".
If after the retake exam, the student does not meet conditions 1 and/or 2, the maximum grade they can obtain will be 4.8.
Laboratory safety warning: Students who are involved in an incident that may have serious safety consequences may be expelled from the laboratory and fail the subject, regardless of the assessment modality selected.
Both for the continuous assessment modality and the single assessment modality, the procedure for reviewing the final grade will be equivalent.
Use of artificial intelligence: Restricted use – In this course, the use of Artificial Intelligence (AI) technologies is permitted exclusively for support tasks, such as bibliographic or information searches, or translations. The student must clearly identify which parts have been generated using this technology, specify the tools used, and include a critical reflection on how these have influenced the process and the final outcome of the activity. Lack of transparency in the use of AI in this assessable activity will be considered a breach of academic integrity and may result in a partial or total penalty in the activity grade, or more severe sanctions in serious cases.
Academic fraud: In the event that a student commits any irregularity that may lead to a significant variation in the grade of an assessment activity, that activity will be graded with 0, regardless of any disciplinary proceedings that may be initiated. In the event that multiple irregularities occur in the assessment activities of the same course, the final grade for that course will be 0.

Software
In this subject, the use of Artificial Intelligence (AI) technologies is allowed as an integral part of the development of the work, provided that the final result reflects a significant contribution of the student in the analysis and personal reflection. The student will have to clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how they have influenced the process and the final result of the activity. Lack of transparency in the use of AI will be considered a lack of academic honesty and may lead to a penalty in the grade of the activity, or greater penalties in cases of seriousness.
