The first International Conference on Nanoenergy will be held in Perugia , Italy during July 10-13 2013. The aim of Nanoenergy2013 is to bring together researchers, engineers, academicians as well as industrial professionals from all over the world and from different disciplines interested in the subject of micro and nanoscale energies. Energy at small scales is a cross-disciplinary field that covers both theoretical and experimental aspects of fundamental and applied sciences ranging from nanotechnology to statistical physics, from computer science to biomedicine. This conference, supported by the European Commission through the “Toward zero power” initiative, provides opportunities for the delegates to exchange new ideas and application experiences face to face, to establish business or research relations and to find global partners for future collaboration.
