Materials for Energy Technology (MET)


This topic has as main objectives the acquisition of knowledge in the field of technology associated to most important materials used in power energy systems, in order to become able to select and/or design the most adequate systems and materials for a specific electric application. The students should acquire scientific knowledge in electric, magnetic and superconductor materials and associated common corrosion processes. In the end, they should be able to understand manufacturer’s technical information, to select adequate materials for a specific application and to design more efficient and reliable power systems. Students should also develop soft skills such as: ability to categorize priorities during the analysis of a technical problem, ability to make choices and take decisions and improvement of written and oral communication skills. The final objective is to contribute to a more interdisciplinary profile, in order to improve employability.

Teaching method

This subject will be presented in theoretical and theoretical-pratical classes. The participation of experts in a specific topic could also happen.

Evaluation method

This subject will be evaluated according to one of the following methods:

 a) 2 Tests (MT) + Research Work (RW)

 Final Classification (FC)  = 0,70*MT Average + 0,30*TP

 com MT  Average = (0,5*MT1+0,5*MT2) >= 9,5 val   and    RW >= 9,5 val.

  b) Final Exam (Ex) + Research Work (RW)

   Final Classification (FC) = 0,70*Ex + 0,30*RW

 with Final Exam >= 9,5 val.   and    RW >= 9,5 val.

 In both cases, the student will be approved only if his/her final mark will be equal or higher 9,5 values (in a 0-20 scale).

 If necessary, the teacher responsible for the subject can require an oral exam to evaluate (or, re-evaluate) the theoretical and/or the practical component of the subject.
