Sustainable Development Goals
Learning Goals
Students should acquire fundamental knowledge on methodologies and analytical techniques involved in
characterizing materials. Their knowledge should encompass the range of structural and chemical characterization techniques most commonly used nowadays, both in research and industry. They should be able not only to understand the theoretical background of the different techniques but also to identify advantages, disadvantages and limitations of each.
Additionally, the students should understand the theory and methodology underlying ancillary systems with emphasis on vacuum systems, and they should understand the importance of the accuracy and be able to find, evaluate and apply standards of ASTM and ISO.

Teaching Methods
The teaching is carried out in theoretical lectures, which operate in a modular regime, and laboratory classes. The process of teaching/learning is based on students work, supported by bibliography and notes taken during lectures and individual research, and based on interactive methodologies, seeking the active participation of students in the classes, particularly in the discussion of issues and resolution of problems. The practical component works in coordination and complementarity with the theoretical, using the planning and execution of laboratory work. Group work is incentivated in addition to individual work.
The evaluation is accomplished through an individual written test (E) and evaluation of effort and performance in the laboratory classes and of the report (P). The report should be developed and encompasses a range of materials and techniques covered in the lectures. The final grade is given by NF= 0.4E +0.6P.
