ScienceDaily: New 'Metal Sandwich' May Break Superconductor Record, Theory Suggests:

"'To the best of our knowledge, this alloy structure had not been considered before,' said Stefano Curtarolo, professor of mechanical engineering and materials sciences at Duke's Pratt School. 'We have been able to identify synthesis conditions under which the LiB compound should form. And we believe that if the material can be synthesized, it should superconduct at a higher temperature, perhaps more than 10 percent greater, than any other binary alloy superconductor.'"
