Superconductivity, the mysterious property that allows some elements to conduct electricity with zero resistance, remains largely confined to the lab because it usually happens at extremely low temperatures. At the low temperature levels at which superconductivity is possible, practical applications exploit a magnetic property called the Meissner effect. “When squeezed at enough pressure, using a diamond anvil, using methodologies that do not require super-cool temperatures, this material achieves superconductivity. He noted that the new paper shows data for magnetic properties, which is the accepted yardstick for establishing superconductivity, given that zero resistance is difficult measure with instruments. The earlier paper too had such data, he noted, but it later transpired that “they had used data processing methods that were not scientifically acceptable”.
