South Korea Superconducting Material Breakthrough？ A global verification competition opens.

　　From the evening of August 2nd to the early morning of August 3rd, Beijing time, Shanghai Key Laboratory of High Temperature Superconductivity of Shanghai University, Professor Liu Xiaobing from the School of Physical Engineering of Qufu Normal University, and Professor Sun Yue from the School of Physics of Southeast University successively released the experimental results of reproducing "LK-99" materials by their respective teams, further pushing the keyword "room temperature superconductivity" to a climax on social networks. So far, a large number of well-known institutes at home and abroad, including Shanghai University, Qufu Normal University and Southeast University, have participated in this competition on the reappearance of superconducting properties of superconducting substance "LK-99", and a global verification competition has started.

　　The experiment of superconductivity reappearance in bilibili University is very hot.

　　What is "LK-99"? "LK-99" is a new achievement recently published by the research team of Korea Quantum Energy Research Institute on the professional paper preprint collection website arXiv. The research team claims that this is a kind of copper-doped lead apatite material with room temperature superconductivity, which can realize superconductivity under normal pressure and room temperature, and its superconducting critical temperature even exceeds the boiling point of water, up to 127℃. Superconductivity describes a material or state that exhibits superconductivity, and its full name is superconductivity. At a certain temperature, the resistance of superconducting materials will suddenly disappear and the current can flow without loss. However, at present, all superconducting materials need to be superconducting in a harsh environment.

　　Therefore, compared with the materials that need to be superconducting in high-pressure and low-temperature environments in the past, the materials of the Korean research team will have subversive significance to all walks of life if they are proved to be true. As South Korea's "Central Daily News" said: "If superconductivity at normal temperature and pressure is proved to be true, it will be enough to win the Nobel Prize". However, the reappearance results of other laboratories in the world cast doubt on this new material.
