‘Superconductors are materials which, when cooled below a certain temperature, become perfect conduc-tors, i.e., they present zero resistance to the passage of electric current which consequently passes through them without any loss of energy. The exhibition, com-posed of panels, photos, videos, industrial prototypes and working models, has been visited in Bologna by students and professors from the scientific departments of the University, as well as by school groups from secondary schools and Technical Institutes. At the Meeting, the exhibition will be renewed and enlarged with particular focus on the applications of superconductors in high energy physics, in the magneto-hydrodynamic production of energy, in the construction of nuclear fusion reactors, in medical diagnosis and in many other leadingedge technology sectors. Superconductivity is one of the most extraordinary di-scoveries of this century. Superconductor materials also allow the levitation of magnetic objects. Prototypes of trains capable of speeds of up to 500 km\/h without touching the rails on which they run, and of magneto-hydrodynamic propelled ships are already a reality, while in the near future it should be possible to produce, transport and store large quantities of energy without dissipation. Until only a few years ago, superconductivity took place only at extremely low temperatures, just above absolute zero. The recent di-scovery (1987) of super-conductive ceramics at temperatures above that of liquid nitrogen (-196\u00b0C) has further renewed the fascinating prospects of super-conductive technology.’<\/p>\n","protected":false},"excerpt":{"rendered":"
