How true or false is the dream paper 'realizing superconductivity at normal temperature and pressure'?
by
The state in which the electrical resistance becomes zero and the Meissner effect is observed is called superconductivity . Superconductivity was thought to be a phenomenon that occurs below a certain temperature, but a paper has been published stating that ``a substance that becomes superconducting at room temperature and normal pressure'' has been published and is attracting a great deal of attention. Quite skeptical voices have been raised about this paper, and the opinions of each research institution and experts on the same paper are summarized in the Internet forum SpaceBattles .

On July 22, 2023, a paper was published stating that ``a substance that becomes superconducting at room temperature and normal pressure'' has been developed. The paper was published by the research team of the Quantum Energy Research Center, a research institute in South Korea, and the team succeeded in making the copper-added lead material 'LK-99' superconducting at room temperature and normal pressure. .

Superconductivity was basically thought to be realized by lowering the temperature to minus 200 degrees, but the LK-99 developed by the research team at the Quantum Energy Research Center realizes a superconducting state even in an environment of up to 127 degrees. is possible. Science, a scientific journal, explains in detail about LK-99, a superconducting material that overturns the common sense developed by the research team, so if you want to know about its characteristics, please refer to the following article. please give me.

If it is possible to create superconducting materials at room temperature and pressure, 'the problem of heat generation that hinders efficient operation in electronic devices will be resolved, and CPUs, GPUs, and memories will become faster and more efficient than before.' and that maglev trains such as maglev trains could be the lowest cost means of travel.
However, since this paper was published on the preprint server arXiv, there was a need for verification. Users of the Internet forum SpaceBattles summarize science-related articles and papers in which research institutions and experts have commented on the paper.
From the left, the organization, country, credibility of the claim, progress, results, notes, and references are summarized, and 'N/A' means not applicable. The references on the right end have links to articles and papers that summarize the opinions of research institutions and experts, and you can check the citations of the original paper by clicking the memo part.
There are 6 cases where the credibility of the claims is 'high' (4 cases by research institutes, 2 cases by amateur experts), and cases where the credibility of the claims is 'slightly high'. 3 cases (3 opinions by amateur experts), 2 cases where the credibility of the claim is 'slightly low' (1 opinion by a research institution, 1 opinion by an amateur expert), claims 3 cases (2 opinions from research institutes, 1 opinion from amateur experts).
For example, the credibility of the Beijing Aerospace University Department of Materials Science and Engineering claims is 'high', the progress is 'completed', the result is 'failed, paramagnetic semiconductor is produced', and the reference is dated 2023. The paper published on July 31 is linked . In this paper, magnetic levitation cannot be confirmed even if a superconductor is placed on a magnet.
In addition, the National Institute of Physics of India has verified the content of the paper several times, but it has all 'failed'.
Even comments from other research institutes ``They (Quantum Energy Research Center) look like real amateurs'' ``It seems they don't have much knowledge about superconductivity'' ``We judge that it is probably an illusion'' Denial Although there are many similarities, Huazhong University of Science and Technology and Iris Alexandra have partially succeeded in verification.
