'Unconventional' Nickel Superconductor Excites Physicists
A new family of superconductors is exciting physicists. Compounds containing nickel have been shown to carry electricity without resistance at the relatively high temperature of 45 kelvin (-228C) -- and without being squeezed under pressure.

Nature: Physicists at the Southern University of Science and Technology (Sustech) in Shenzhen, China, observed the major hallmarks of superconductivity in a thin film of crystals of nickel oxide, which they grew in the laboratory. "There's a huge hope that we could eventually raise the critical temperature and make [such materials] more useful for applications," says Dafeng Li, a physicist at the City University of Hong Kong. The ability of the Sustech researchers to precisely engineer the material's properties is huge boon in trying to use nickelates to unravel the theory behind unconventional superconductivity, says Lilia Boeri, a physicist at the Sapienza University of Rome.
