Thisvolumereportsthemajorpartofthescientificcontributionsofthefirstinternational workshoponSuperconductingNano-ElectronicsDevices(SNED)heldinNapoli,Italy,at theendofMay2001. Theaimoftheworkshopwastofocusonrecentexperimentalandtheoreticalresultsin thefieldofsuperconductingnano-electronicsdevices. Itcombinedphysicswithpresent andfuturetechnologicalapplications:bothfundamentalandappliedaspectswerecovered.
