Objectives

Objectives 

One intends to focus the fundamental concepts of Condensed Matter, emphasizing the applications to engineering and life problem systematization and solving. Fundamental proprieties of Condensed Matter will be verified in experimental laboratory sessions, involving the comprehension of experimental setups, data collecting and treatment systematization and elaboration of scientific reports.

Teaching method

Theoretical lectures, once a week. 

Practical sessions in the laboratory every week, and problem resolution sessions.

Evaluation method

Assessment

Theory:  2 tests and / or final exam 

Theory grade: simple average of the grades of the tests or the exam grade

A successful  result in the theory assessment is required  - minimum grade: 10 in 20

Frequency

Frequency is mandatory. Obtained with the laboratory sessions and with minimum 2/3 assistance to the theoretical lectures and the problem resolution sessions.

A successful  result in the laboratory assessment is required  - minimum grade: 10 in 20

Final grade

The final grade is the average of 60% of the theory grade and 40% of the laboratory grade.

 Sudents with a previous year(s) successeful assessment in the laboratory component are only assessed relative to the theory and the final grade is given by the theory grade
