University of Rochester researchers who demonstrated superconducting materials at room temperatures last fall, now report a new technique in the quest to also create the materials at lower pressures.

In a paper published in Physical Review Letters, the lab of Ranga Dias, assistant professor of mechanical engineering and of physics and astronomy, describes separating hydrogen atoms from yttrium with a thin film of palladium.

"This is a completely new technique that nobody has used before for high pressure superhydride synthesis," Dias says.
