Place: Building J
Bellaterra Campus, 08193 Bellaterra
Teaching Period: 26 June to 14 July
The aim of the subject is to provide a general and broad introduction to the multi-disciplinary field of nanoscience and nanotechnology. During the course the students will acquire the basic knowledge of why and how the physicochemical properties change at the nanoscale. The students will become familiar with the more important materials that have boosted the field of nanotechnology and with the typical techniques that allow the observation, characterization and manipulation of matter at the atomic, molecular and supramolecular level. The subject also aims at acquiring basic knowledge of the nanofabrication tools from the top-down approach widely used in microelectronics and micromechanics to the bottom-up approach of chemistry/biochemistry. The recent scientific and technology work in the nano world will be presented to demonstrate the potential of nanoscience and nanotechnology in diverse areas such as medicine, biotechnology, chemical industry, information and communication technology, production and storage of energy, synthesis and manufacture of new materials, etc. It is also expected that the student becomes aware of the ethical, social and economic implications of this new discipline.
