Course objectives

Energy production, harvesting, storage, use and saving represent crucial issues for the development of sustainable  economies and societies. The development of advanced materials along with their relevant technologies plays an important role in implementing effective solutions for these challenges. The present course is intended to face these problems by presenting the properties of a few classes of materials that are playing  an increasing role in the life cycle of energy. Among them, metallic low temperature superconductors as well as high-temperature superconducting oxides will be discussed from the point of view of their structure, properties, governing physics, main applications, economical opportunities and limits of their performances.   

Moreover, materials for energy storage,  energy harvesting and batteries will be discussed with special attention to hydrogen storage materials and thermoelectric materials. Principles for energy storage, energy harvesting and batteries will be described together with the strategies for the development of materials suitable for the applications.

Learning assessment methods

The exams will be in person.

Remote examinations can be requested by students, provided that they are in one of the conditions specified by the University rules: a) health problems, b) living out of the Piedmont region, and c) in quarantine.

Examinations will be oral only and split into 2 sets of questions to be taken in series in the same session, each of them concerning the topics dealt with during each course module: i) superconductors, and ii) H storage and batteries.

Assessment criteria will be:

  • Ability to coherently and extensively organize a speech to introduce one of the topics of the course;
  • Critical thinking and capability to correlate different aspects of the course and to compare them with more general scientific knowledge;
  • Correct use of technical language;
  • Fluence in topic discussion;
  • Ability to discuss and prove mathematical formulae when requested.

Each of the 2 series of questions will results in independent marks expressed out of 30. 30 cum laude represents the maximum possibile outcome.

These 2 marks will be averaged after discussion beween the teachers in a non-deterministic way, where the mathematical average will represent the guideline, but the final outcome could also be slightly different follwing the contents of teachers' disussion.
