Indigenous alchemy subverts science？ Koreans really cut a dash this time!

　　The indigenous alchemy was originally the specialty of South China, but it was unexpectedly used by South Koreans this time to synthesize LK-99, a superconducting material at room temperature under normal pressure. Although it has not been fully disclosed at present, it is proved by domestic verification that the high probability is reliable.

　　As more information surfaced, the line was basically clear. In the next few years, the global alchemy era is expected to officially open, and high-temperature furnaces in laboratories around the world are running around the clock. It is said that many material suppliers have been sold out.

　　In fact, as early as the 1950s in the former Soviet Union and Eastern Europe, some scientists had put forward some theories of room-temperature superconductivity. In the 1980s, a Rhodian scientist claimed to have made lead-based room-temperature superconductors, but there was no news since the war.

　　According to the screenshots of some articles posted by netizens, there are also people involved in the field of room temperature superconductivity in China. In 1987, there was an article on the transition from semiconductor to superconductor in the journal of low temperature, and in 1988, there was an article in the journal of Zhejiang University that the resistance of the sample suddenly dropped by more than one order of magnitude at room temperature, and it was thought that there might be room temperature superconductivity in the sample.

　　It is quite similar to the latest LK-99 crystal prepared today, which is sintered and doped with copper. Finally, it is pointed out that the gas phase environment and annealing temperature are very important in the process. Unfortunately, the research failed to continue.

　　It was not until 1994 that Cui Dongzhi, a professor at Korea University, put forward his own theory of superconducting bands between atoms on the basis of predecessors, and thought that one-dimensional inorganic polymer chains could be superconducting, and he took his students Li Shipei and Jin Zhixun to look for such substances.

　　In 1999, Jin Zhixun finally discovered the anomaly of the data through copper-doped apatite, but it was very difficult to reproduce it, because it could not be reproduced all the time, and finally it went away, and Li Shipei and Jin Zhixun gradually withdrew from the research field.

　　In 2017, Professor Cui Dongzhi was seriously ill, and the students went to visit him. Before his death, Professor Cui Dongzhi specially asked Li Shipei and Jin Zhixun to repeat the strange phenomena that had not been studied in those years, hoping to find room temperature superconductors.

　　So the research was restarted, new partners were introduced, and in an accidental attempt, the data of that year were reproduced, and the key to synthesis was also found. Now it seems to be very similar to the conclusion of the paper in the Journal of Low Temperature in 1987, that is, oxygen was introduced during the final annealing and the annealing temperature was critical.

　　After finding the key to synthesis, it was much faster. LK-99 crystal was not only confirmed, but also showed in diamagnetism and zero resistance tests. However, the preparation process was difficult to stabilize, and even Jin Zhixun could only do it himself, which was not necessarily successful.

　　In this case, there is a contradiction within the Korean research team, and some people have sent out papers with preparation methods. Unexpectedly, it has aroused great interest from domestic research teams. After all, alchemy is an ancestral craft, and it is indeed highly accepted, and the preparation method is simple, so many teams began to copy it.

　　Up to now, a number of teams such as Huake, Chinese Academy of Sciences, Southeast University and Qufu Normal University have completed trial production, and they have performed well in diamagnetism, at least confirming that Koreans are not lying. The team of Southeast University even measured that there was a zero resistance state at 110K under normal pressure.

　　At present, it is not completely confirmed that LK-99 can be used as a room-temperature superconductor, but there is great hope. The theoretical calculation by the National Laboratory of the United States and Shenyang Institute of Chinese Academy of Sciences also thinks that LK-99 may be a room-temperature superconductor. Next, more teams will intervene and constantly explore how to improve the purification method to see if we can really master the room-temperature superconductor technology.

　　After all, room temperature superconductivity can bring about great changes, which has attracted many laboratories in the world to participate in it. Moreover, through the continuous update of social media, South Korea has also set up an expert group to prepare for a formal test of LK-99 finished products.

　　It is also right for South Korea to make a big splash this time. After all, at least they have spent decades researching and looking for LK-99, which is commendable and has found a more feasible way for scientists.

　　At present, there are theories, as well as specific room temperature superconducting material LK-99. At least, it will continue in this direction, and the direction is correct. Moreover, China is also moving quickly, hoping to make a more perfect material as soon as possible.

　　The era of global alchemy is coming soon, and room temperature superconductivity is a technology that can really change the times.
