LK-99’s creators claim it is a superconductor at room temperature and pressure Rokas Tenys/Alamy
Recent claims that a material called LK-99 conducts electricity perfectly at room temperature and pressure have kicked off an incredible flurry of experimental activity. There are several ways to test if something is such a superconductor, however the flurry has yet to find much scientific consensus. Creating pure samples of LK-99 in the lab and determining their quality is also proving difficult.
Unlike conventional conductors such as metal wires, superconductors allow electricity to pass through them without any resistance, which means that no energy…

We have corrected the conditions under which signs of zero resistivity have been found.
