$American Superconductor(AMSC)$ Today, according to one report, a team of scientists from the Physics Department of Southeast University in Nanjing, China, have measured 0 resistance in a sample of LK-99 they synthesized from scratch. They claim to have observed superconductivity up to a temperature of 110 kelvin (-163°C) and an abrupt drop in resistance between ~300K and 220K, which is consistent with the Korean team’s results. Previous day, the team from the Huazhong University of Science and Technology in Wuhan has posted a video on social media showing that they have successfully verified the synthesis of LK-99 crystal that can be magnetically levitated for the first time, with larger levitated angle than that of the previous sample obtained by the South Korean team . They say that their sample shows the levitation phenomenon as Meissner effect of a superconductor at room temperature and atmospheric pressure below its critical temperature, Tc, which is above 126.85°C (400K). They also say that their sample shows zero resistance and diamagnetic properties, which are characteristic of superconductors. Even though the South Korean team was requested to withdraw their paper, more evidence is emerging that supports their claim. The day of a complete revolution might be closer than anticipated.
