South Korea has recently brought to the attention of the global scientific community with two high-profile papers on room temperature superconductivity that detail a synthesis method for a room-temperature superconducting material called LK-99. This breakthrough meant that LK-99 was relatively easy to prepare, the raw materials needed were widely available, and the synthesis time took only three days. As a result of this momentous discovery, scientists from around the world rushed to replicate the material in hopes of revealing its potential scientific value.
However, the preparation of room-temperature superconducting materials is not trivial. Small changes in the synthesis process can have a significant impact on the final crystal growth. Some scientific teams may need years of effort to stabilize a parameter, but fortunately, the raw material for LK-99 is quite common, and there are feasible synthesis methods, making the preparation process relatively simple.
Choi Dong-sik, a founder of ISB superconductivity theory, has been proposing related theories for nearly 30 years. However, although he first synthesized LK-99 in 1999, it was not studied in depth at the time, and the study was shelved. Later, before Choi Dong-sik's death, he entrusted the task of continuing his research to two students. It wasn't until 2017 that they revived the study, and in the last three months they made a major breakthrough, followed by the release of a sensational paper, although some key information was hidden in the paper. However, the South Korean research team has promised to revise the paper and is willing to personally guide the synthesis of LK-99.
The research of LK-99 is not limited to South Korea, the Chinese Academy of Sciences and Huake teams in China have also actively participated in the replication work, and successfully prepared the finished LK-99. Although the Chinese Academy of Sciences has not yet released detailed data, according to the data shared by the Huake team, one of the samples significantly showed magnetic transitions from 0 to negative values, similar to the results observed by Korean scientists in 1999, indicating the potential feasibility of this research direction.
Encouragingly, there are some disagreements within the Korean research team, so they released two papers so that more research teams can join the research. This move is equivalent to pointing out a way for other scientists to prepare anti-magnetic jump materials, which seems to be only one step away from the realization of room-temperature superconducting materials.
However, it is regrettable that the two LK-99 samples previously prepared by the South Korean research team have allegedly been obtained by the United States. This could mean that subsequent findings won't be publicly available, as the Nobel Prize seems only a matter of time before a major breakthrough in room-temperature superconductivity occurs.
Science is a process that requires constant experimentation and failure, and neither Korean scientists nor researchers in other countries can spend a lifetime failing to make a breakthrough. The theory of superconductivity has been proposed for 30 years, and LK-99 was discovered in 1999, but only now has it been possible to achieve room-temperature superconductivity. I look forward to the successful replication of LK-99, and also hope that China can catch up in this field and contribute more possibilities to the scientific community.
