But the newest—and most perplexing—candidate comes from a team of South Korean researchers, who in two separate papers detail the properties of a material they call “LK-99”, a lab-made material containing lead, oxygen, phosphorus, and sulfur. According to the paper, LK-99 showcases tell-tale signs of the Meissner effect (it levitates) and it is supposedly a superconductor with a Tc of 260 degrees Fahrenheit at ambient pressure, meaning it can basically operate in any environment on Earth.
