Superconducting hydrogen? Researchers model three hydrogen-dense metal alloys

Physicists have long wondered whether hydrogen could be transformed into a metal or a superconductor -- the elusive state in which electrons can flow without resistance. They have speculated that certain pressure and temperature conditions could achieve these goals. Now high-pressure researchers have modeled three hydrogen-dense metal alloys and found pressure and temperature trends associated with the superconducting state -- a huge boost in understanding how this abundant material could be harnessed.[...]
