New ‘metal sandwich’ may break superconductor record, theory suggests< /a>. ‘After an exhaustive data search for new compounds, researchers at Duke University’s Pratt School of Engineering have discovered a theoretical “metal sandwich” that is expected to be a good superconductor. Superconductive materials have no resistance to the flow of electric current. The new lithium monoboride (LiB) compound is a “binary alloy” consisting of two layers of boron – the “bread” of the atomic sandwich – with lithium metal “filling” in between, the researchers said. Once the material is synthesized, it should be superconductive at a higher temperature than other superconductors in its class, according to their results.’
