In the subject, the mechanical, thermodynamic and microscopic properties of the systems dominated by interfacial effects are studied from an applied chemical-physical point of view. The following interfaces are studied: gas-liquid, liquid-liquid, gas-solid and solid-liquid, and the importance of each of them in chemical systems will be evaluated. Thus, issues of such practical importance as detergency, the formation of foams, aerosols, the types of colloidal systems and their formation and stability mechanisms will be addressed in order to determine their applicability in fields such as food, cosmetics, industry of oil, etc. Finally, the main types and characteristics of nanostructures and nanomaterials are also shown. The theoretical contents are complemented by simple laboratory practices.

It will be based on master classes, accompanied by problem classes in which the proposed exercises will be discussed together. Works related to the science of colloids and surfaces will be proposed, in which it is intended to get deeper insight in aspects not addressed in the master classes. These works may be done individually or in pairs. Likewise, the practical aspects of this subject will be addressed in laboratory sessions, in which, detailed written reports will be required for the interpretation and treatment of the obtained results.

Laboratory practices will be mandatory.

A minimum score of three points out of ten will be required in each of the types of evaluation activities indicated above in order to access the average and pass the course.

In accordance with the regulations governing the evaluation of students in official degrees, the evaluation tests must be kept by the department at least until the end of the following course. Likewise, not submitting to the final test will be graded as “not presented”.

Nevertheless, students may be evaluated by a final evaluation system, regardless they have participated in the continuous evaluation system. To do this, students must submit (writing) to the faculty responsible for the subject the waiver of the continuous evaluation, in a period of 9 weeks from the beginning of the semester according to the academic calendar of the Faculty. This final evaluation test will consist of evaluation activities comparable to those used in the continuous evaluation system.

The use of books, notes, as well as telephone, electronic, computer, or other devices or devices by students will be forbidden, unless otherwise indicated by the faculty.

In accordance with the regulations governing the evaluation of students in official degrees, the evaluation in the extraordinary call will be carried out exclusively through the final evaluation system. The positive results obtained by the students during the course will be kept, in the case of having obtained negative results through continuous evaluation, these results will not be maintained for the extraordinary call, in which the student will be able to obtain 100% of the grade. Extraordinary evaluation test will consisted of evaluation activities comparable to those used in the ordinary call.

The use of books, notes, as well as telephone, electronic, computer, or other devices or devices by students will be forbidden, unless otherwise indicated by the faculty.



In case on-line assesment is required:

Resources (if online): The tools to be used will be those available in eGela. It will be possible to have notes.

Note: When a student has connection problems at the time of completing any of the questionnaires, they must notify the teacher by email or in the BBC session during the test, in order to offer you an alternative way of communication.



If the teachers consider it appropriate, they can carry out an oral ratification of what has been done in the case of an online test. In all cases, the evaluation will be carried out following the Protocol on academic ethics and the prevention of dishonest or fraudulent practices in the evaluation tests and in academic work at the UPV / EHU. In particular, the guidelines for action in the event of possible fraud, copying or plagiarism will be followed (Article 4).
