Learning Goals
In this curricular unit it is intended that the students acquire fundamental knowledge on techniques and methods for materials analysis and characterisation, with special focus on those commonly used, both in research and industry. At the end of the course the students should be able to: understand the theoretical foundations of the different techniques and methods; select appropriate technique(s) and method(s) with a view on the domain to study and required information for specific applications, recognizing the complementarity and identifying advantages, disadvantages and limitations; correctly interpret results on the basis of the underlying theoretical principles; know and apply standards of the different techniques and methodologies in order to validate the results. It is also intended to develop the students capacity for autonomy in the planning and execution of laboratory tasks, in the organisation and presentation of the information, as well as their integration into research.

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 component. Group work is encouraged in addition to individual work.
The continuous evaluation is accomplished through an individual written exam (NE) and evaluation of effort and performance in the laboratory classes and of the developed report (NP). The final grade is given by: NF=0.4NE+0.6NP. If the student chooses final evaluation scheme, the final mark will be the one obtained in the exam.
