A South Korean research team recently released a paper saying that it has achieved room temperature superconductivity, which has attracted widespread attention around the world, but has also been questioned.。And members of the research team said the paper was flawed and that a member of the department's team had released it without authorization, and that the team had now asked to take the paper off the shelves。A superconductor is a material that can conduct current with zero loss, but it is extremely difficult to use in practice because it usually needs to be cooled to an extremely low temperature of around -196 degrees Celsius and requires extremely high pressure to become superconducting.。Therefore, if superconductivity can be achieved at room temperature and pressure, it will be of great significance to the development of human science and technology.。In recent years, several research teams have claimed to have achieved room temperature superconductivity, but they have all been proven to be fake.。
