Chapter 444 I Don’t Understand Superconductivity, but I Understand South Korea
While Xu Chuan was busy verifying the strong anti-magnetism of KL-66 material, the first batch of materials industry paid attention to KL-66 material and conducted the results of the replication experiment on it, which had already 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 its replication experiment results on the Internet.
Like the Chuanhai Materials Research Institute, the materials professor of the School of Materials at the University of Rochester also failed to detect the Meissner effect on the replicated KL-66.
Not only that, in the case of only one set of replication experiments, the research team of the University of Rochester failed to even replicate the strong anti-magnetic effect.
At the same time, on the other side of China, the research team of the Huazhong University of Science and Technology also published the results of the replication experiment on arxiv.
Unfortunately, the research team of the Huazhong University of Science and Technology also failed to observe the Meissner effect on the replicated KL-66.
However, unlike the research team of the University of Rochester, because of the relationship of conducting multiple sets of replication experiments, the Huazhong University of Science and Technology successfully observed the suspension phenomenon, indicating the potential of superconducting properties that this new material may have.
Of course, it is only possible.
After all, in this replication experiment, in addition to the failure to observe the Meissner effect, the resistance of the replicated KL-66 material itself is not zero, and it can even be said to be quite high.
However, the research team of the Huazhong University of Science and Technology said that this may be due to the insufficient purity of the material they synthesized. In the future, they will further conduct replication experiments to obtain more data.
The two replication results have caused heated discussions on the Internet.
Some people believe that KL-66 is not a room-temperature superconducting material. After all, whether it is Xu Chuan's simulation calculation results or the replication results of the United States and China, it shows that it is not a superconducting material, and it is more likely to be a strong magnetic material.
Some people think that KL-66 still has potential. After all, the research team of the Huazhong University of Science and Technology has successfully replicated the magnetic levitation effect. If the purity of the KL-66 material is further purified, the resistance may go down.
In addition, there are also people asking when the replication results of the Chuanhai Materials Research 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 are looking forward to the results of this big guy.
While these netizens were happily discussing, someone on the arxiv website paid attention to the paper uploaded by Xu Chuan at the first time.
[arxiv! Professor Xu uploaded the paper, and the replication results are out! ]
[What do you say? What does Chuan Shen say? ]
[The Chuanhai Materials Research Institute conducted three sets of replication experiments, and none of them observed the Mai effect, but one set had a strong antimagnetic effect and observed the suspension effect. According to the paper uploaded by Chuan Shen, South Korea's KL-66 is basically dead. ]
[The magnetic levitation effect was observed. According to the statement of the Huazhong University of Science and Technology, doesn't this just show the possibility of superconductivity? Maybe the purity of the replicated material is not enough? ]
[Indeed, maybe the Koreans kept a trick and did not give all the replication steps. After all, this is room temperature superconductivity. If you develop it, will you announce it all? It's impossible to think about it. 】
【Heh, stop struggling. This time, Chuan Shen uploaded not only the results of the replica experiment, but also the principle of the strong magnetism of the KL-66 magnetic levitation effect. I don't understand the principle, but from the results, it is not a superconductor at all, but the material has the same magnetism as a magnet. 】
【KLyl semi-metallic material, the spin-orbit coupling of Cu atoms has an impact on the material. What the hell is this talking about? 】
【Worship, you are worthy of being a real boss. 】
【(▽｀) This is probably the fastest end of room temperature superconductivity, right? Chuan Shen's move is a killer. 】
【Disperse, if room temperature superconductivity can be rubbed out like this, humans 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 South Korea. 】
【Laughing to death, where are those Koreans 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 materials science community have been waiting for his replica experiment results.
As soon as the relevant replica experiment results were uploaded, they were downloaded by countless people.
At the University of Rochester in the United States, Professor Schmuel Heath, a top expert in the field of superconducting materials, held a newly printed document that still exuded the smell of ink and read it carefully.
In the field of superconductivity, he has full say.
The barium-yttrium-copper oxide high-temperature superconducting material, which is famous in the United States and even the world, was discovered by him.
In addition, the first batch of replica experiments on KL-66 uploaded to the Internet were done by him.
After flipping through the paper in his hand, Professor Schmuel Heath 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 still hope for KL-66?"
Sighing, Professor Schmuel Heath replied: "From the paper, I'm afraid there is little hope, or even almost no hope."
After a slight pause, he then said with emotion: "As expected of the famous Professor Xu, he found the mechanism behind the magnetic levitation of KL66 material in such a short time. If it was done by others, even if I did it myself, it might not be possible to get results in one or two months."
Although I really hope that 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 unfortunately, judging from the latest paper, the hope has been shattered.
Although it is only a paper on arxiv, who in the academic world does not know the habit of Professor Xu?
If he is not absolutely sure, he will not easily draw conclusions about something and make it public.
And 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 are theoretically flawless.
After hearing the answer, the assistant and student beside him was silent for a while, and then said: "This is probably the fastest time for news in the field of room temperature superconductivity to end, right?"
It's not that there has been news about room temperature superconducting materials in the past.
The room temperature superconductivity in the fields of ternary hydrides and hydrogen sulfide has been a big deal, and it will basically last for several months in the materials industry before it ends.
After all, it takes time to replicate and verify.
And this time, from the time the KL-66 paper was uploaded from South Korea to now, has it been ten days? The conclusion has almost been decided.
Hearing the students' sigh, Professor Schmuel Heath smiled and said: "Actually, this is good, so that everyone's time will not be wasted."
"After all, academic disputes, especially in the extremely important field of room temperature superconducting materials, often require a lot of time for many scientific researchers to verify."
"And now, I believe that after this paper comes out, I'm 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 a basic norm.
On this basis, some academic disputes or academic frauds will mislead the judgment of the academic community, lead to wrong conclusions, and undermine the normativeness of academic research.
For example, in 2014, the academic fraud case of "universal cells" STAP cells by Haruko Obokata, who was called "national treasure" and "Island Country Marie Curie" by the small island country, shocked the world.
Because of the importance of universal cells, many researchers in the biomedical field of various countries have paid attention to it, and they have invested personnel to replicate and verify it.
However, after wasting a lot of time, manpower and material resources of many scholars, it was found that this was just a fraudulent scientific research.
There is no doubt that this is an extremely bad behavior.
And this time, after Professor Xu's move, KL-66 will probably end soon, and the stock market will be gone before it has time to cut a wave of leeks.
However, what makes Shmuel Heath feel a little strange is that after reading Professor Xu's research paper on the magnetic levitation mechanism of KL-66, he always feels that the paper is missing something.
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 from 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 magnetic levitation effect of KL-66 material.
But as a top material personnel, when he read the paper, he always felt that something was missing from the paper, incomplete, and seemed to be deliberately hidden.
However, he was not very proficient in computational materials science, so he couldn't find out where the problem was, nor could he figure out what the hidden thing was.
