PROFESSOR BIO INFORMATION
Dr. María José Esplandiu received her Ph.D. in Chemistry at the National University of Córdoba, Argentina in 1995. She did postdoctoral studies at the Technical University of Dresden and Ulm in Germany, at the University of California at Los Angeles and at the California Institute of Technology in USA. In 2004 she obtained a Ramón y Cajal position in Spain, at the Autonomous University of Barcelona. Since 2009, she is a CSIC tenured Scientist at the Catalan Institute of Nanoscience and Nanotechnology and associate professor at UAB. Her research focuses on surface (electro)chemistry, surface nanoengineering, and interfacial phenomena for applications in carbon based nanoelectronics, sensors, and micro/nanomotors.
Dr. Xavier Borrisé is the responsible for the Nanolithography Laboratory of the Largest Clean-Room in Spain (IMB-CNM), with users from different institutions working in Electron Beam Lithography, Focused Ion Beam or NanoImprint technologies, among others. He is collaborating with researchers in topics as Nanofabrication of Nanoelectromechanical, Nanoelectrodes and Nanoelectronics Devices, as well as lithography developments with other Clean-Room Facilities.
Nanotechnology is emerging as a very powerful tool capable of revolutionizing and changing our way of life. Nano-objects and nanostructures exhibit new phenomena and properties that are unthinkable in the macroscopic world. Such new phenomena and properties can be exploited to provide solutions for the great social challenges in medicine, energy and the environment. The student is invited to embark on a fascinating journey to discover the great power of the small.
The objective of the subject is to familiarize the student with the concept of nanoscience and nanotechnology and to provide a thorough grounding of the scientific reasons behind the different behaviour that materials exhibit when they are miniaturized and how the nanomaterials can be observed, manipulated or synthesized in the nanoscale. On the other hand, it is intended to explain and raise awareness of the use of these nanomaterials for innovative technological developments in areas such as health, environmental remediation, information / communication, energy production / storage, synthesis and manufacturing of new materials, etc.
It is also expected that the student becomes aware of the multidisciplinary training that must be acquired to work in this field and the ethical, social and risk implications that these new disciplines may entail. The course will be complemented by some demonstrative practices in the classroom that will help to understand the fascinating world of materials at the nanoscale level.
