　　The myth of "room temperature superconductivity", which shocked the world's scientific and technological circles and even stirred up the global capital market rapidly, seems to be shattered "super fast" after a "viral spread"-

　　On July 26th, the South Korean research team announced the discovery of "room temperature superconductivity", which attracted a lot of attention and related disputes followed. At the same time, countries quickly repeated experiments, including some universities in China and related companies and laboratories in the United States, but the results were not consistent.

　　On August 2nd, Korea Superconducting Cryogenic Society announced the establishment of "LK-99 Verification Committee" to verify this. On August 3rd, the expert committee publicly stated that "LK-99" is not a room temperature superconductor.

　　According to the report of Yonhap News Agency quoted by the World Wide Web on August 3rd, after the research team of Korea Quantum Energy Research Institute published the paper on manufacturing superconducting substance LK-99 at normal temperature and pressure, the South Korean Superconducting Cryogenic Society, after scientific judgment, concluded that LK-99 was not a room temperature superconductor, because the experimental materials did not fully show the "meissner phenomenon", and the members of the Korean research team refused to submit samples for testing.

　　As we all know, if room temperature superconductivity can be realized, subversive breakthroughs will occur in important fields such as energy transmission and transportation. Therefore, although the research on room temperature superconductivity has been staged many times, it still deserves more expectation and unremitting efforts, and scientists around the world are bound to advance wave after wave.

　　South Korea's scientific research team has always been "infighting"

　　The "room temperature superconductivity", dubbed "viral propagation", began with a paper published by a Korean research team. This paper demonstrates that a substance named "LK-99", which is synthesized by ordinary copper silicate and copper phosphide by a simple method, has superconducting properties at room temperature and pressure.

　　Li Shuopei, Jin Zhixun, scientists from Korean Quantum Energy Research Center, and Quan Yongwan from KU-KIST Graduate School of Fusion Science and Technology are co-authors of this paper, among which Li Shuopei is the chief signatory.

　　In fact, there were two papers on the same subject published on the same day, and the other one was more similar to the one published in the Korean Journal of Crystal Growth and Crystal Technology in April and accepted peer review in a more formal format.

　　Its signers, besides Li Shuopei and Jin Zhixun, include American Korean expert Jin Xuande, and Lin Chengyan, An Xiumin and Ou Genhao, both of whom belong to the Korean Quantum Energy Research Center. However, they lost the right of Yong Wan, who was dismissed from the Quantum Energy Research Center in April.

　　The article published in April, with the same signature of six people, has the right to be forever without Eugen Hao. This arrangement and combination of signatures like playing a Rubik's cube is really incompatible with scientific papers that require rigorous style of study. Now, the Korean research team has started "infighting" again.

　　On July 28th, Jin Xuande, who was excluded from the "online celebrity Edition", that is, the most widely circulated and influential three-person signature edition, said that both papers were published without permission and had many defects, but they did not attract much attention.

　　But just after August, Li Shuopei, the chief signer of "online celebrity Edition", suddenly confirmed through authoritative media such as Yonhap News Agency that the publication of the paper was "without the permission of other authors" and was "published without authorization" by Quan Yongwan, who was expelled from the Korean Quantum Energy Research Center.

　　As Li Shuopei is not only the chief signer of related papers in various editions, but also the name of the LK-99 material that was accidentally generated as early as 24 years ago, his words stirred up a thousand waves, and for a time, rumors such as "the author withdrew the manuscript" were rampant.

　　In fact, this is probably a misunderstanding of the "infighting" of the Korean research team. Li Shuopei neither retracted the manuscript nor changed his mind, but still insisted on his "great discovery" and "scientific conclusion". Therefore, its statement not only has the meaning of eliminating the right of eternal power from the "group that grabs merits", but also has the function of "crisis public relations" for the discovery of room temperature superconductivity, which has aroused widespread doubts in the professional field.

　　I hope that the research is no longer just "the wolf is coming"

　　Why did Li Shuopei engage in "crisis public relations"? Because, as the skeptics have pointed out, there are too many "unreasonable" places in this "viral spread".

　　First of all, two non-peer-reviewed papers with similar contents were published on the same unorthodox platform on the same day, and their arguments were widely spread as "scientific conclusions", "unlike the means of scientists".

　　The two arguments in his thesis are also "non-compliant"-one of the grounds for demonstrating the existence of superconductivity is "no resistance", which can only be effective if it is completed in the pure sample test, and the research team has actually not synthesized the pure sample of "LK-99" so far, let alone used it for the resistance-free test.

　　As for the "meissner phenomenon" based on the second part, that is, the effect that superconductors can levitate on magnets, the uploaded video is not only vague but also full of doubts.

　　Moreover, as Clark, a professor of chemistry at Oxford University, said, even if the suspension is completely established, it can only prove that the material has diamagnetism, which is only a necessary condition for superconducting materials, far from a necessary and sufficient condition. Because there are many materials in nature that are not superconductors, but they also have diamagnetism.

　　In fact, since the publication of this paper, due to its "viral spread" influence, many large and small laboratories and teams around the world are scrambling to put into repetitive testing, but so far there is no clear result.

　　Obviously, no matter what kind of test results, LK-99 can't be completely proved to be a low-cost superconducting material at room temperature and pressure that meets the standard of "argument"-and the basis of this "viral transmission" is the so-called "three constants". Even, the paper itself has been pointed out that there are many "fatal injuries".

　　Therefore, Li Shuo Peicai tried to carry out "crisis public relations", kicked out the signers who had been fired, and emphasized "going through the process to seek peer review" in an attempt to make up for the "procedural irregularities".

　　The most interesting thing about this matter is that the madness of global superconducting concept stocks, the most direct effect of "viral spread", continues regardless.

　　In South Korea, some superconducting concept stocks rose by 260% and 170% respectively in six trading days, and hit the daily limit for three consecutive days; In the United States, US stocks rose by more than 100% before superconducting trading. Despite warnings from many securities analysts, the madness of leverage continues.

　　On August 2, the United States reported that "the global superconducting market will be US$ 6,772.09 million in 2022, and it is expected to reach US$ 1,736.731 million in 2032, with a compound annual growth rate of 9.97% from 2023 to 2032". This obviously reflects the attachment and urgency of the investment leverage sector to this "super heat conduction".

　　As far as investment leverage is concerned, they won't wait for the conclusion that "this is really normal temperature and pressure superconductivity". They just need to know the word "now or never, and they can make a lot of money.

　　Of course, from another perspective, the crazy pursuit of the concept of room temperature superconductivity in the capital market actually shows that people are full of expectations for this difficult but possibly world-changing scientific research. We also hope that with the unremitting efforts of scientists, the research field of room temperature superconductivity is no longer just "wolf coming", and it can really benefit human society as soon as possible.
