- Contents
- This course deals with the topic of energy from the point of view of Physics. It is organised in three main sections: I Fundamental principles: from classical thermodynamics to non-equilibrium statistical mechanics, with specific reference to processes at micro and nanoscale. II Thermodynamics of information: we study the way in which energy is dissipated in information and communication devices with special reference to the fundamental physical limits. III Energy Harvesting: we study the way energy is collected from ambient sources and transformed in order to be used by mobile electronic devices in the "internet of things perspective".
