Technology of Nanomaterials
Knowing different production, deposition and processing techniques of nanomaterials in different forms; nanoparticles, thin films and fibers. Identifying advantages and limitations of the different techniques depending not only on the type of material to obtain but also on the processing technique itself. Knowing the importance of process parameters and how to select the most suitable process parameters to process a given material. Knowing how to select the suitable technologies according to the type of material to be obtained. Planning the processing steps according to the characteristics of the material and the desired application.

The lectures will be supported by powerpoint slides. The objectives of each lesson and reading support are explained on the slides.
The practical classes will be conducted in the laboratory, where students perform exploratory experimental activities of the topics covered in the lectures. Additionally, some practical classes will be devoted to the elaboration of the practical report.
Evaluation shall consider a theoretical component (50 %) and a practical component (50%), distributed by 5 elements of assessment:
3 theoretical tests (20%+20%+10%);
Evaluation of lab activities will be done by:
A project report (45 %);
Evaluation of Lab class development (5 %).
Presence to all lab classes and its evaluation are mandatory for students to be approved in the course. Final grade will be obtained by the weighted average of all the above cited elements. Approval in the course also requires a minimum grade of 9.5 in the average of the grades of the 3 theoretical tests.
Students will be excluded from the course if one of the above conditions is not satisfied.
