One stone stirred up a thousand waves, and Xu Chuan's answer in class was quickly passed on to the Internet.

Of course, along with it, uploaded the results of his simulation calculations of the KL-66 material.

His judgment of KL-66 material, at this node of the explosion of flow in the field of room temperature superconductivity, can be said to have caused a heated discussion among melon-eating netizens in an instant.

[KL-66 material, Chuanshen came forward to deny it, it is not a room-temperature superconducting material, but a strong magnetic material! ] 】

[Hey, empty joy, if it's really cool, with controllable nuclear fusion technology, I have no doubt that the electricity bill can be reduced to a dime a kilowatt. 】

[It's just a simulation calculation, it can't be true.] Before the results of the reproduction are out, in the absence of a conclusive conclusion, it is impossible for anyone or any organization to stop, after all, the stakes are high, and arrogance means defeat. 】

[Indeed, this wave of Kawajin is a bit reckless. It's okay to wait for the results of the replication experiment to come out before expressing your opinion. 】

【？？？ Kawajin can't express his opinion, so you are labeled as arrogant? He didn't say a certain result, just a preliminary judgment based on calculation and analysis, and the results will be uploaded to arxiv. 】

[Outrageous, arrogant, I'm afraid you can't even understand the paper uploaded by Chuanshen, so you can understand the big truth. 】

[I don't understand superconducting materials, but I understand the country of South Korea, and I hope that South Korea, a country addicted to counterfeiting, loves to make superconducting materials, and it is better to count on a small life to be more reliable. 】

[Hahahaha, 6, lore!] 】

Compared with the heated discussion on the Internet, the material industry's opinion on this matter is much calmer, but many people are very surprised.

No one expected that the famous Professor Xu would stand up and express his opinion.

Although researchers in the materials industry hope that this KL-66 material is a room-temperature superconductor than those who eat melons, the spirit of scientific research allows them to maintain the necessary calmness in the face of this kind of thing.

Of course, this also has something to do with the fact that the fork experiment is still basically ongoing.

According to the steps of the paper on arxiv, the steps of replicating the experiment are actually quite simple, but it is more time-consuming.

Even if the replication experiment was carried out at the first time, just like the Chuanhai Materials Research Institute, the results would have to wait another day or two before they came out.

Before the results of the reproduction are out, few researchers in the field of materials have come forward to express their opinions and opinions.

After all, if you get slapped in the face, it's still a shame.

Of course, there is no problem at all for someone like Professor Xu, who has already done simulation calculations and then expressed his opinions and opinions.

Even if there is a gap between the final replication experiments and these simulations, there is nothing to say.

After all, theories are theories, and experiments are experiments.

It's just that many researchers in the field of materials are surprised that he moves so fast.

It seems that it has not been three days since the publication of the paper related to the KL-66 material on arxiv, and the results of the targeted formation energy calculation, phonon spectrum, and tightly bound model have been made.

This speed is inevitably a bit exaggerated.

Institute of Materials Research, Polytechnic University, California.

Two middle-aged men in white lab coats are leisurely sipping coffee in the laboratory, waiting for the copper and phosphorus mixture to be calcined in a high-temperature furnace.

According to the Arxiv paper, this step requires calcination at a temperature of 550 degrees Celsius for 48 hours to allow the mixture to react and form cuprous phosphide crystals.

In the process, it is only necessary to stabilize the temperature of the vacuum furnace, and no other operation is required.

This is easy for today's various computer-controlled material equipment. As a result, they had plenty of time to chat and relax during the experiment.

"I heard that Professor Xu of Huaguo has completed the simulation calculation of KL-66 materials? Indicates that it is just a strong magnetic material? ”

Drinking coffee, Hornby Eden looked at his colleague and asked.

Speaking of this, my colleague nodded and said, "Well, the relevant paper has been uploaded to arxiv, judging from the data of Professor Xu's simulation calculation paper, I am afraid that this time the KL-66 material is a room-temperature superconductor There is little hope." ”

"If I'm not mistaken, that Professor Xu seems to be a mathematician, right?" Hornby Eden asked after a moment's thought.

Hearing this, my colleague Berne Jones smiled and said, "It's true that he is a mathematician, but he is also a top physicist, a top astronomer, a top materials scientist, and even a top engineer, designer, and so on." ”

"Don't forget, the high-temperature copper-carbon-silver composite superconducting material was developed by him. I heard that the purpose of his original development of high-temperature superconducting materials was to control nuclear fusion technology. ”

"Incredible, mathematics, physics, astronomy, materials, and also solved the technology of controlled nuclear fusion, has the cross-domain effect lost its effect on him?" Hornby Eden shook his head exaggeratedly and sighed.

"Who knows, this is probably another Newtonian Gauss-level demon." Byrne Jones said with a smile.

Shrugging his shoulders, he continued: "To be honest, even without Professor Xu's calculations, I am actually not very optimistic about this KL-66 material. ”

"Not to mention whether room-temperature superconductivity can be achieved so easily, the 'fake news' released on room-temperature superconductivity alone occurs almost every year, and then the stock market cuts a wave of leeks, and slowly there is no news, which can neither be confirmed nor denied."

"But the difference this year is that the stock market hasn't taken off yet, and it was slapped by Professor Xu."

There's nothing wrong with what Byrne Jones said.

If we look at the events of superconducting materials at room temperature that occur every year in history, the relevant heat will last for at least ten days and a half months.

Then, during this period, the stock market for superconducting materials will rise sharply and then slide again.

Capital will cut a wave of leeks in it, and even cooperate with it in person when necessary, such as making a replica of experimental data, confirming that this material is very likely to have room temperature superconductivity or something, and harvesting it again and again.

However, this year, before they could act, they were slapped and killed.

Even if the replication experiment is still ongoing, no one can be sure whether this KL-66 superconducting material has superconducting properties, but the stock market has not risen at all.

No way, the reputation of the name 'Xu Chuan' is too big.

Although it is only some speculative calculations, judging by the mathematical ability of this big guy, it is basically impossible for his calculations to have any problems.

After all, this is a Fields Medal winner, a super fierce man who has solved two millennial problems by himself.

This has also led to the superconducting materials sector, which should have been extremely hot, is now as calm as a pool of stagnant water, and even fell slightly.

Xu Chuan didn't pay much attention to this.

He didn't even know that because of the opinions he expressed in class, the dreams of some capitalists to cut leeks were shattered.

He was in the laboratory, conducting superconductivity tests on the replica KL-66 material.

Although the probability that KL-66 is a room-temperature superconductor is already very small from a material calculation point of view, Xu Chuan still hopes that it may be true.

After all, for a scholar in the field of materials, it is undoubtedly quite exciting and exciting to see a way to break the existing materials research and development system.

Three sets of replication experiments resulted in three copies of KL-66 material according to the paper.

Three materials, one of which Xu Chuan personally verified, and the other two were handed over to two researchers in the field of superconducting materials.

Superconducting tests on superconducting materials are familiar to him.

To see whether a material is a superconducting material, the core indicator is whether it has the 'Meissner effect', and the first thing he did was naturally this.

However, unfortunately, after tossing back and forth several times, Xu Chuan was convinced that the reproduced KL-66 material he was assigned did not have the Meissner effect.

There is no doubt that the first forking experiment was a failure.

Of course, he did not give up and deny it directly, and in the following time, he successively tested the magnetic field, resistance, critical temperature and other aspects of the synthesized material.

In the end, it was confirmed that the material in his hand had a certain degree of diamagnetism, but it was quite weak.

As for the resistance, when I tested it several times before and after lowering the temperature, it was found that the resistivity dropped sharply at 250 K (about -23 °C), but the decrease was less than zero.

At 7.1 K, the resistance of the material drops sharply again, and the wireless resistance is close to zero.

This result is basically consistent with the test of KL-66 in the computational material model.

At room temperature, it does not exhibit superconductivity, and only exhibits superconducting properties when the temperature is reduced to 7.1 K.

However, this is meaningless, and at a temperature of 7.1 K, there are many, many materials that can achieve superconducting properties. And in this material, the superconducting critical temperature of lead is -265.95 °C (7.2 K)

In this case, it's hard not to wonder if this critical temperature transition is the material itself, or the lead inside.

After completing all the tests according to the standards, Xu Chuan took off the experimental gloves on his hands.

Judging from the material in his hand alone, the hope that KL-66 material is a room-temperature superconductor has been dashed, and it also makes him sigh.

However, verifying a material is not something that can be done with a single replication experiment.

There are many accidental factors, and if you need to ensure that there are no errors in the replication experiment, you should do at least three sets of controls.

After waiting for a while, the results of the other two sets of tests also came out.

Judging from the results, all observations of the Meissner effect have failed.

The three copies of KL-66 material that were reproduced according to the standard process did not have the Meissner effect.

However, to Xu Chuan's surprise, the material numbered 'No. 2' showed a semi-magnetic semi-suspension effect similar to the diamagnetic semi-suspension effect of the video sent by South Korea.

Although subsequent testing confirmed that it was only a diamagnetic, it still caught his attention.

If we can find the mechanism of this diamagnetism, there may be some other discoveries.

On the other side, in the laboratory, looking at the test report in his hand, Fan Pengyue said with a smile: "It seems that this time I can slap a wave of South Korean netizens in the face." ”

The Meissner effect was not detected in all three groups of materials made by different people, and it can be said that the probability that this KL-66 material is a room-temperature superconductor has been reduced to the extreme.

"A slap in the face? What's going on? In the laboratory, Chai Su, another researcher who does superconductivity testing, asked with some curiosity.

Fan Pengyue smiled and said, "Didn't our boss disclose the results of the simulation calculation before, indicating that this KL-66 material is more likely to be a strong magnetic material than a superconductor." ”

"Then the people on the South Korean side were not convinced, and all kinds of expressions were not convinced."

"If they scold on the Internet in their own country, forget it, and they have chased it to our country, I don't believe you open the scarf, β the software to take a look, and now the online bar has become an article."

"There are those who stand on our boss, and there are those who stand on each other, and there are many people who eat melons."

"Anyway, there is a topic of room-temperature superconducting materials now, and it's quite lively."

Hearing this, Chai Su couldn't help frowning and asked, "No, I just want to know, judging by the results made by the calculation, what is there to disagree with?" Still swearing? ”

Fan Pengyue smiled and said: "Normal, the old tradition over there in South Korea is also an old habit over there." ”

"After all, our relationship with South Korea is relatively 'delicate', and we look down on each other. In addition, there are some extremist groups over there who are more crazy, and they can't tolerate sand in their eyes, and they like to chase and bite people. ”

Hearing this, Xu Chuan, who was reading the test report, took a curious look, then took out his mobile phone from his pocket, silently opened the scarf, and searched for KL-66-related topics.

[Assi, what is this cub! 】

[It must be envying our room-temperature superconducting materials, so you slander it? 】

[The results of a simulation calculation, we have actually carried out a superconductivity test, and the magnet can be stably suspended on the KL-66 superconducting material, which is not much more powerful than the so-called calculation?] 】

[I doubt that Professor Xu did this to slander him in order to preserve the status of high-temperature superconducting materials in his hands.] After all, as soon as our KL-66 comes out, I'm afraid that no one will buy his materials in the future. 】

Under some of the popular videos of the scarf, you can indeed see some 'familiar' words.

However, these words were basically sprayed into a sieve by the Chinese people.

In terms of spraying people, there is probably no netizen in that country whose combat effectiveness can compare to that of the Chinese people.

"Send me the electronic copies of the reports of these three replica experiments."

After sweeping the hot search on the scarf, Xu Chuan raised his head and said to Fan Pengyue.

On the other side, Senior Brother Fan Pengyue smiled and nodded in response.

It's going to be a good show this time.

Although these South Korean netizens who chased and sprayed have been sprayed into a sieve by Chinese netizens, I have to say that this kind of behavior is indeed quite disgusting.

Because of a different opinion, chasing to other countries to scold, probably only people from that country can make it.

If it were any other scholar, they would probably not have paid attention to these messages.

But if he didn't see it, it would be fine, and now that he sees it, it won't be his character if he doesn't respond after the results come out.

Now the results of the replication experiment have come out, which is completely consistent with the results of the simulation calculations.

He couldn't help but feel happy when he thought about the faces of the South Koreans who were spraying the Mikoto on the Internet after seeing the three replica test reports.

Who do you think is bad for you to spray? Let's spray this.

The most important thing is how many times have you cheated in the field of science, and you don't have a pen in your heart?

In '05, the 'research results of embryonic stem cells', which was known as one of the world's three major academic frauds, were purely deliberately fabricated.

Fifteen years later, the 'biggest fraud case' in academia also occurred in South Korea, when nearly 200 professors were brought to court.

Why, how long has it been? It's okay, do you forget the pain of the scar?
