Course Overview

Module objectives

The objective of this course is to give the students skills in advanced methods for materials characterization in order that they can select the most suitable one for a specific property as, for example, the in depth characterization of a material at a nanometric level. For that, the students have access to the available testing equipments in UC, to perform several practical and laboratorial works which will be presented as scientific and technical reports. The experimental skills of the students in performing research work are also goals to be achieved in this course.
