Materials Science in Bioengineering

Not applicable.

The lectures are aimed at the presentation and development of materials that constitute the core of the CU. Lectures are following a script based on slides, frequent use of the backboard and dialogue with the students. In the problem solving classes, practical examples are presented aiming at an improved understanding of the lectures and the students are helped to solve them on their own. In these classes, some subjects concerning the application of different classes of materials are proposed to the students to be developed and presented orally. The execution of laboratory works will focus on the use of techniques for materials mechanical properties determination and for polymeric materials preparation, complementing the proposed learning outcomes. The final evaluation includes a “continuous” component which grades the oral presentations. The final grade is obtained with 40% (8 points) for the above mentioned component and 60% (12 points) for the final exam.

With this curricular unit is intended to provide students with concepts about the structure, properties and applications of plastics, ceramics and composites materials, metals and alloys. The students should be able to: i) At instrumental level: carry out analysis and synthesis in the organization and management of information necessary for planning, in the context of specification and choice of the most suitable materials for a given application. ii )At personal level: be competent in critical thinking and having the ability to communicate. iii) At systemic level: be competent for autonomous learning starting from a given set of knowledge; adaptability to new situations, along with the ability to apply theoretical knowledge obtained. The CU introduces and critically analyses relevant aspects of Biomaterials, with particular attention to their use in pharmaceutical and medical applications. These issues are focused on the mutual relations structure-property-application of biomaterials.
