Teaching language

Suitable for English-speaking students

Objectives

Obtain advanced training in modern concepts involving Materials Science namely in the new trends and research of materials and their functionalities.

Master techniques of analysis of the internal structure of materials.

To know methods of determining the distribution of atomic and molecular units of materials and their interaction.

Knowing in detail the physical properties of materials

Understand the role of shape and dimensions in changing the physical properties of materials

Know the relevant aspects of multifunctionality

Acquire advanced training in the control of the functionality of the materials considering the interdependence of their physical properties with the aim of their application in advanced technology.

Learning outcomes and competences

Provide advanced training in the field of multifunctional nanostructured materials to enable students learning key concepts in this area and apply them in this area of knowledge, but also in advanced technological applications. The program includes an introduction to the properties and advantages regarding the use of a wide range of materials in applications, where functionality has major technological impact. In the following chapters are dealt in detail various families of materials with high potential for multifunctionality purposes. It is expected that students become familiar with the methodology that allows improving the response of materials to stimuli by interacting processing, structure and properties. At the closing of the UC will be presented various principles of operation of devices, technologies and/or sensors in order to consolidate the acquired knowledge.

Teaching methods and learning activities

The multifunctionality of materials is an interdisciplinary interface that covers various topics related to our day to day, with sensors, transducers, electronic motors, hard disks, aerospace coating, batteries, smart textiles, biomaterials coating for latest electrical services. In this way, this curricular unit was supported by the development of competences of analysis of problems of the concept, passing through the understanding of the physical phenomena and ending in the applications. The methodology of clinical teaching has relied on a strong interaction between the child-teacher through continuous evaluation with lectures and written assignments. The fields of research and research on their areas of training are more difficult to detect. Such methodology has as main advantages the transmission of knowledge through the contact with the different perspectives, allowing students to learn some methodologies of problem solving and different perspectives, be a level scientist or a technological level, thus enriching the experience of students in practical situations. On the other hand, the application of the knowledge acquired in real cases is proven more effective and more solved than the learning objectives of the curricular unit. Scheduled visits to existing research laboratories in the management of materials and production applications and their applications. In this way, it is expected that students have not acquired the tools and concepts of training of a teaching system. In this UC, we also focus on the aspects directed to the industrial and European market in order to adapt the students to the labor market.
