The scientific community is still scrambling to confirm the recent revolutionary claim by Chinese scientists that they have created a room-temperature, ambient-pressure superconductor. But with enough brainpower looking into the subject of the LK-99 material, it's bound to be a matter of time before the superconductivity claims are fully confirmed or denied.
Once again, researchers in China seem to be at the forefront: today, scientists with the Physics Department of Southeast University, a top university in Nanjing, China, have reported measuring zero electrical resistance, a key requirement for superconductivity, in a sample of LK-99 they produced from scratch. However, that comes with the caveat that they could only achieve the properties at -163C, not at the room temperature touted by the original paper. As with other efforts from other teams, two of which claim to have confirmed certain other aspects of the claimed superconducting breakthrough, the new results from the Southeast University team are preliminary — the team is still studying different methods of fabricating the material, with plans to provide more results in the future. Other research teams are also still working to replicate the initial claims.
