The course “Characterization of solids and surfaces” belongs to the Process and Product Engineering module of the Master in Chemical Engineering. The course is elective, and it is taught during the second semester of the first year. It is taught by members of the Department of Chemical and Environmental Engineering and by instructors external to Universidad de Oviedo.

The main objective of this course is instructing the student on the fundamentals and applications of the most important instrumental techniques for characterization of solids and surfaces of interest in Chemical and Environmental Engineering, such as metals, polymers, catalysts, membranes, adsorbents, etc.

Although there are no compulsory requirements, apart from those obligatory to comply with the Master, students are recommended to have knowledge on Physical Chemistry, Thermodynamics, and Transport Phenomena.

This course aims to develop the following skills:

General skills:

CG1

Be able to apply the scientific method and the principles of engineering and economy to formulate and solve complex problems of processes, operations, systems and services where matter changes in composition, state, or energy content, characteristic of the chemical industry and other related sectors, such as pharmaceutical, biotechnological, material, energy, food, or environmental.

CG4

Be able to do the appropriate research, undertake the design and manage the development of engineering solutions, in new or partially known environments, relating creativity, originality, innovation and technology transfer.

CG6

Be able to analyse the continuous development of product and processes, taking into consideration technical, health, safety and environmental aspects, as well as economic and quality reliance concerns.

The specific skills are:

All materials will be available via the Virtual Campus, including the lectures presentations and the problems and practical examples to be solved.

Lectures on theoretical or practical subjects will be given by the instructors, helped by the corresponding graphic materials.

Laboratory and field practice sessions will take place in the labs of the Departamento de Ingeniería Química y Tecnología del Medio Ambiente, Universidad de Oviedo, other labs in Universidad de Oviedo, or external. Their aim is the knowledge by the students of the apparatuses and methods of the characterization techniques studied.

In Group Tutorials the students will present orally short works, prepared in small groups, which will be discussed.

The evaluation of the students will be carried by evaluation of the work and reports of the lab/field practice, a written exam, and the team work presented orally.

Attendance to the lab/field work sessions is compulsory; in duly justified cases, an attendance higher than 80% will be accepted. Active participation in all of them will also be taken into account.

In order to pass the course, the qualification obtained in lab/field practice and in the team work cannot be less than 50% of its maximum value. Likewise, the final written exam cannot be less than 40% of its maximum value. If these minimum qualifications are not met, the course is not passed.

To obtain a minimum of 5 points out of 10 in the evaluation of lab/field practice, it is essential to have obtained a minimum of 4 points in each and every one of the individual reports of each practice. This implies having performed all the required simulations and tasks.

Final written exam. At the end of the course, there will be a written exam, consisting of 5 theoretical or theoretical/practical questions (50% of the exam grade), and 2 problems (50% of the exam grade). In order to pass the course, the grade in the theoretical part should be at least 30% of the assigned 5 points, and the grade in the problems part should be at least 30% of the assigned 5 points. The grade of the written exam corresponds to 70 % of the course final grade.

The value of each of the evaluation systems, both in the ordinary and extraordinary calls, expressed as a percentage, will be as follows:

If these conditions are met, the final mark is calculated using the abovementioned percentages.

The qualification of the Lab/field practice and Group work will be maintained in all the course calls of the corresponding academic year.

In the following calls within the same academic year, the students will present themselves to the aspects not surpassed in the first call of the course, and the evaluation will be made according to the criteria of the first call.

Resources:

Audiovisual media will be used which, as indicated previously, will be available to students in advance. The use of specialized bibliography available through the library network of the Universidad de Oviedo (BUO), located especially in the Faculty of Chemistry, as well as networked resources (electronic publications and databases) will be promoted.

The Department of Chemical and Environmental Engineering has different characterization techniques that will be used in the course: optical microscopy, nitrogen adsorption porosimetry, scanning differential calorimetry, temperature programmed techniques (TPR, TPO). The Scientific-Technical Services of Universidad de Oviedo have the following techniques: TEM, SEM, EDX, thermogravimetry, XRD, XPS, IR-FT. It is possible to visit other institutions where other techniques (mercury porosimetry, scanning tunnelling microscopy) are available.
