Chapter 444 I don't understand superconductivity, but I understand South Korea

When Xu Chuan was busy verifying the strong diamagnetism of the KL-66 material, the first batch of material circles paid attention to the KL-66 material, and the results of the replica experiment on it have come out.

The first to speak out was the School of Materials under the name of the University of Rochester in the United States, which announced the results of its own replica experiment on the Internet.

Like the Chuanhai Institute of Materials, the professor of materials science at the School of Materials at the University of Rochester also failed to detect the Meissner effect on the replica KL-66.

Not only that, the research team at the University of Rochester even failed to reproduce the strong diamagnetic effect when only one set of replica experiments was done.

At the same time, on the other side of Huaguo, the research team of the Chinese Academy of Sciences also published the results of the replica experiment on arxiv.

Unfortunately, the research team of the Chinese Academy of Sciences also failed to observe the Meissner effect on the reproduced KL-66.

However, unlike the research team at the University of Rochester, the Chinese Academy of Sciences successfully observed the levitation phenomenon due to multiple sets of replica experiments, indicating that this new material may have the potential of superconducting properties .

Of course, it's just possible.

After all, in this replica experiment, except that the Meissner effect was not observed, the resistance of the replica 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 insufficient purity of the materials they synthesized, and they will do further replica experiments in the future to obtain more data.

The results of the two replicas aroused heated discussions on the Internet.

Some people believe that KL-66 is not a room temperature superconducting material. After all, whether it is the simulation calculation results of Xu Chuan, or the replica results of the United States and Huaguo, it shows that it is not a superconducting material, and it is more likely to be a superconducting material. Strong magnetic material.

I 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. If the purity of the KL-66 material is further purified, the resistance may drop.

In addition, some people are also asking when the results of the reproduction of the Chuanhai Materials Research Laboratory will come out.

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

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

[arxiv! That Professor Xu uploaded the paper, and the result of the reprint came out! 】

【How to say? What did God Kawa say? 】

[Chuanhai Materials Research Institute has done three sets of replica experiments, none of which have observed the effect, but one set has a strong diamagnetic effect, and the levitation effect has been observed. According to the paper uploaded by Chuan Shen, the KL-66 in South Korea is basically cool. 】

[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 material is not enough? 】

[Indeed, maybe Bangzi saved a lot of money, and the re-engraving steps were not given. After all, this is room temperature superconductivity. If you develop it, will you announce it all? Impossible if you think about it. 】

[Oh, don’t struggle, what Chuanshen uploaded this time is not only the results of the re-engraving experiment, but also the strong magnetic principle of the KL-66 magnetic levitation effect. Conduction is just that the material has the same magnetic properties as a magnet. 】

[KL-66 is an inversion asymmetric Weyl semimetal material. The spin-orbit coupling of Cu atoms has an impact on the material. What are you talking about? 】

[Worship, you are indeed a real boss. 】

【(▽`) Is this the fastest time for room-temperature superconductivity to end? Chuan Shen's shot is lore. 】

[Let’s go, if room temperature superconductivity can be rubbed out by hand like this, human beings would have stepped out of the Milky Way long ago. 】

[Le, I still have the same opinion. Although I don’t understand superconducting materials, I understand the country of South Korea. 】

[Laughing, where are those sticks from 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, countless people in the material science community are already waiting for the results of his replica experiment.

As soon as the relevant re-engraving experiment results were uploaded, they were downloaded by countless people.

In the United States, at the University of Rochester, Professor Schmuel Heath, a top expert in the field of superconducting materials, held a document that had just been printed and still smelled of ink, and read it carefully.

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

He discovered the barium-yttrium-copper oxide high-temperature superconducting material that is famous in the United States and even in the world.

In addition, the first batch of KL-66 replica experiments uploaded on the Internet was led 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, what's the result? Is there any hope for KL-66?"

Sighing, Professor Schmuel Hiss replied: "From the perspective of the paper, I'm afraid there is little hope, and it can even be said that there is almost no hope."

After a slight pause, he then said with emotion: "As expected of the famous Professor Xu, in such a short period of time, he has found the mechanism behind the magnetic levitation of KL66 material. If it is for others, even if I do it myself, a There may not be any results in two months."

Although it is hoped that the KL-66 material is a room temperature superconductor, after all, if this is true, it means that materials science will usher in a major change and leap.

But sadly, judging by the latest paper, that hope has been dashed.

Although it's just a paper on arxiv, who in the academic world doesn't know the habits of that Professor Xu?

If he is not fully sure, he will not easily draw a conclusion on a certain matter and make it public.

And judging from the papers uploaded on arxiv, whether it is the replica experiment of KL-66 material, or the mechanism behind the magnetic levitation phenomenon of KL-66 material, that Professor Xu has made a fairly complete explanation. Those data In theory, there is nothing wrong with it.

Hearing the answer, the assistant and student beside him was silent for a while, and then said: "This is probably the fastest time for the news in the field of room temperature superconductivity to end, right?"

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

The previous room-temperature superconductivity in the fields of ternary hydrides and hydrogen sulfide, whichever was not a big hit, at least basically lasted for a few months in the material industry before it came to an end.

After all, it takes time to reproduce and prove.

And this time, from the uploading of KL-66 papers in South Korea to the present, is there ten days? The conclusion is almost reached.

Hearing the student's exclamation, Professor Schmuel Hiss smiled and said, "Actually, this is quite good, so that we won't waste everyone's time."

"After all, such things as academic disputes, especially in the extremely important field of room temperature superconducting materials, often require a lot of time for many researchers to verify."

"But now, I believe that after this paper comes out, I am afraid that not many research institutions will focus on this, and everyone can continue to do their own things."

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

On this basis, some academic controversies, or academic fraud and other incidents will mislead the judgment of the academic community, lead to the emergence of wrong conclusions, and undermine the normative nature of academic research.

For example, in 2014, Haruko Obokata, known as the "National Treasure" and "Madame Curie of the Island Country" by the small island country, caused a sensation in the world with the "universal cell" STAP cell academic fraud case.

Because of the importance of pluripotent cells, many researchers in the field of biomedicine from various countries have paid attention to it, and have invested personnel to carry out replica verification.

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

There is no doubt that this is extremely bad behavior.

And this time KL-66, after the shot of Professor Xu, will probably come to an end soon, and it will be gone before the stock market has time to cut a wave of leeks.

However, what made Schmuel Hiss feel a little strange was that after reading Professor Xu's research paper on the mechanism of KL-66 magnetic levitation, he always felt that there was something missing in the paper.

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

If it is simply to prove the source of the magnetic levitation mechanism, this paper is definitely enough. The paper clearly explains the source of the mechanism of the magnetic levitation effect of the KL-66 material.

But as a top-level material engineer, when he read the paper, he always felt that there was something missing in the paper, incomplete, and it seemed to be deliberately hidden.

However, he is not very proficient in computational materials science, but he can't find out where the problem is, and he can't figure out what the hidden thing is.
