When Xu Chuan was busy verifying the strong diamagnetism of KL-66 material, the results of the first batch of experiments in the materials industry that paid attention to KL-66 material and reproduced it have come out.

The first to speak out was the School of Materials at the University of Rochester in the United States, which published the results of its own replication experiments on the Internet.

Like the Kawakai Materials Research Institute, a professor of materials science at the University of Rochester's School of Materials Science also failed to detect the Meissner effect in a replica of the KL-66.

Not only that, but the research team at the University of Rochester was not even able to replicate the strong diamagnetic effect after only one set of replication experiments.

At the same time, on the other side of the Chinese Academy of Sciences, the research team of the Chinese Academy of Sciences also announced the results of the replication experiment on ARXIV.

Unfortunately, the research team of the Chinese Academy of Sciences was also unable to observe the Meissner effect on the replica KL-66.

However, unlike the research team at the University of Rochester, due to the relationship of multiple sets of replication experiments, the Chinese Academy of Sciences successfully observed the levitation phenomenon, indicating the potential of this new material for superconductivity.

Of course, it's just a possibility.

After all, in this replica experiment, except for the Meissner effect, the resistance of the reproduced KL-66 material itself is not zero, and it can even be said to be quite high.

However, the research team of the Chinese Academy of Sciences said that this may be caused by the lack of purity of the materials they synthesize, and they will do further replication experiments in the future to obtain more data.

The results of the two reproductions have caused heated discussions on the Internet.

It has been determined that KL-66 is not a room-temperature superconducting material, after all, whether it is the simulation results of Xu Chuan, or the replication results of the United States and Huaguo, it shows that it is not a superconducting material, and it is more likely to be a strong magnetic material.

Some people feel that KL-66 still has potential, after all, the research team of the Chinese Academy of Sciences has successfully reproduced the magnetic levitation effect, and if the purity of KL-66 material is purified, maybe the resistance will go down.

In addition, there are also inquiries about when the results of the replica of the Kawakai Materials Laboratory will come out.

After all, as early as a few days ago, Xu Chuan publicly stated that the Chuanhai Materials Research Institute was already doing replication experiments, and many people were looking forward to the results of this big bull.

When these melon-eating netizens were discussing happily, on the arxiv website, someone paid attention to the paper uploaded by Xu Chuan for the first time.

【arxiv！ That Professor Xu uploaded the paper, and the reproduction results came out! 】

[How do you say?] What does Kawajin say? 】

[The Chuanhai Institute of Materials has done three sets of replication experiments, none of which have observed the Mai effect, but one group has a strong diamagnetic effect, and the levitation effect has been observed. Judging by the paper uploaded by Kawajin, this KL-66 in South Korea is basically cold. 】

[There is an observation of the magnetic levitation effect, according to the Chinese Academy of Sciences, doesn't this just indicate the possibility of superconductivity?] Maybe it's because the purity of the reproduced material is not enough? 】

[Indeed, maybe the stick left a hand, and the reproduction steps were not given all.] After all, this is room temperature superconductivity, if you develop it, will you publish it all? It's impossible to think about. 】

[Oh, don't struggle, Chuanshen uploaded this time not only to reproduce the experimental results, but also the KL-66 magnetic levitation effect strong magnetic principle, I don't understand that principle, but judging from the results, it is not superconducting at all, but the material has magnetism-like magnetism. 】

[KL-66 is a reversed asymmetric Weyl semimetallic material, and the spin-orbit coupling of Cu atoms has an effect on the material. 】

[Worship, worthy of being a real boss. 】

[(▽')This is the fastest end of room temperature superconductivity, right? Kawajin's shot is a lore. 】

[Disperse, if room-temperature superconductivity could be rubbed out like this, human beings would have stepped out of the galaxy a long time ago.] 】

[Le, I still have that opinion, although I don't understand superconducting materials, but I understand the country of South Korea. 】

[Laughing to death, what about those sticks before? ] Jump, jump again? 】

After figuring out the mechanism of KL-66's strong magnetism, Xu Chuan sorted out the relevant information and uploaded it to arxiv.

As expected, there are countless people in the materials science community who have been waiting for the results of his replication experiments for a long time.

As soon as the results of the relevant replication experiments were uploaded, they were downloaded by countless people.

At the University of Rochester, Professor Schmuel Heath, a top expert in the field of superconducting materials, held a copy of the newly printed materials and exuded the scent of ink in his hand, and read them carefully.

In the field of superconductivity, he has a full voice.

The barium-yttrium-copper oxide high-temperature superconducting material that is famous in China and even in the world was discovered by him.

In addition, the first batch of replica experiments for the KL-66 uploaded to the Internet was done by him.

After flipping through the paper in his hand, Professor Schmuel Hiss took off his glasses and rubbed his eyes.

On the side, his assistant and student couldn't wait to ask, "Professor, how is the result?" Is there any hope for the KL-66? ”

Sighing, Professor Schmuel Heath replied: "Judging from the paper, I am afraid that there is little hope, and even almost no hope. ”

After a slight pause, he then sighed: "The well-known Professor Xu, in such a short period of time, he has found the mechanism behind the magnetic levitation of KL66 material. If it is done for other people, even if I do it myself, it may not be fruitful for a month or two. ”

Although it is very desirable that KL-66 is a room-temperature superconductor, after all, if this is true, it means that materials science will usher in a major revolution and leap.

But sadly, judging by the latest papers, hopes have been dashed.

Even though it's only an ARXIV paper, who in the academic world doesn't know that Professor Xu's habits?

If he is not completely sure, he will not easily draw conclusions about a matter and make it public.

Moreover, judging from the papers uploaded to arxiv, whether it is the replication experiment of KL-66 material, or the mechanism behind the magnetic levitation phenomenon of KL-66 material, Professor Xu has made a very complete explanation, and those data can not find any fault in theory.

Hearing the answer, the assistant and student next to him was silent for a moment, and then spoke: "This is probably the fastest news in the field of room temperature superconductivity, right?" ”

The news of room-temperature superconducting materials is not unheard of in the past.

In the past, room-temperature superconductivity in the fields of ternary hydride and hydrogen sulfide was not vigorous, and at least it would last for a few months in the materials industry before it ended.

After all, it takes time to reproduce and prove.

And this time, is there any 10 days from the South Korean side to upload the KL-66 paper to now? The conclusion has almost been decided.

Hearing the student's exclamation, Professor Schmuel Heath smiled and said, "Actually, it's good, so that you don't waste everyone's time." ”

"After all, academic controversy, especially in the important field of room-temperature superconducting materials, often takes a lot of time from many researchers to verify."

"And now, I believe that this paper is out, and I am afraid that not many research institutions will focus on this in the future, and everyone can continue to do their own things."

For academics, maintaining a rigorous and realistic academic style is the basic norm.

On this basis, some academic controversies or academic fraud will mislead the judgment of the academic community, lead to the emergence of erroneous conclusions, and undermine the standardization of academic research.

For example, in 14 years, Haruko Kobokata, who was called a "national treasure" and "Marie Curie of the island country", caused a sensation in the world's "universal cell" STAP cell academic fraud case.

Because of the importance of pluripotent cells, many scientific researchers in the biomedical field in various countries have paid attention to it, and they have invested in personnel to reproduce and verify.

However, after wasting a lot of time, manpower, and material resources of many scholars, it was found that this was just a fake scientific research.

There is no doubt that this is extremely egregious behavior.

And this time, the KL-66, after having this Professor Xu's shot, will probably end soon, so fast that the stock market will not have time to cut a wave of leeks and it will be gone.

It's just that what makes Schmuel Heath feel a little strange is that after reading Professor Xu's research paper on the mechanism of KL-66 magnetic levitation, he always feels that something is missing from the paper.

It's not that this paper can't be used to prove that the magnetic levitation effect of KL-66 material does not come from the superconductivity mechanism, but something else.

If it is a simple source to prove the magnetic levitation mechanism, this paper is certainly sufficient, and the paper clearly expounds the mechanism source of the magnetic levitation effect of KL-66 material.

But as a top-level material person, when he watched the paper, he always felt that something was missing from the paper, and the incomplete appearance seemed to be deliberately hidden.

However, he is not very proficient in computational materials, but he can't find the problem, and he can't think of what is hidden.

PS: The second is to ask for a monthly pass
