Chapter 442 No Meissner Effect

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

Of course, uploaded together with it are his simulation calculation results of KL-66 materials.

His judgment on the KL-66 material, at this point in the field of room temperature superconducting where traffic is exploding, can be said to have instantly aroused heated discussions among netizens.

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

[Hey, it’s just a joy. It would be great if it really happened. With the controllable nuclear fusion technology, I have no doubt that the electricity bill can be reduced to a dime per degree. 】

[It’s just a simulation calculation, it should not be taken seriously. Before the results of the re-enactment come out, and without a final conclusion, no one or any organization can stop. After all, the stakes are high, and arrogance means defeat. 】

[Indeed, Sichuan God is a bit reckless this time. It’s okay to wait for the results of the replica experiment to come out before expressing your opinion. 】

【? ? ? Sichuan God can't even express his opinion, so he is labeled as arrogant by you? He didn't say a certain result, it was just a preliminary judgment based on calculation and analysis, and the results will be uploaded to arxiv. 】

[Outrageous, to say arrogant, you may not even be able to understand the paper uploaded by Sichuan God, but you already know the truth. 】

[I don’t understand superconducting materials, but I understand the country of South Korea. It’s better to hope that South Korea, a country addicted to counterfeiting, will love to produce superconducting materials, is more reliable. 】

[Hahahaha, 6, a sure kill! 】

Compared with the heated discussion on the Internet, the materials community has a much calmer view on this matter, but many people are surprised.

No one expected that the famous Professor Xu would stand up and express his views at this moment.

Although scientific researchers in the materials field prefer that this KL-66 material is a room-temperature superconductor than the general public, the scientific research spirit allows them to maintain the necessary calmness when facing such things.

Of course, this is also related to the fact that the replica experiments are basically still in progress.

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

Even if the replica experiment is carried out immediately like the Chuanhai Materials Research Institute, the results will not come out for another day or two.

Before the reproduction results came out, few researchers in the materials field came forward to express their opinions and views.

After all, it would be quite embarrassing to be slapped in the face.

Of course, there is absolutely nothing wrong with someone like Professor Xu who has done simulation calculations and then expresses his own opinions and views.

Even if there is a gap between the final reproduction experiment and these simulation calculations, there is nothing to say.

After all, theory is theory and experiment is experiment.

What surprised many researchers in the materials field was that he moved so fast.

It seems that within three days of the KL-66 material-related papers being posted on arxiv, targeted formation energy calculations, phonon spectra, and tight-binding model results have been produced.

This speed is a bit too exaggerated.

Materials Research Institute, Polytechnic University, California.

Two middle-aged men in white coats were drinking coffee leisurely in the laboratory, waiting for the mixed powder of copper and phosphorus to be calcined in the high-temperature furnace.

According to the paper on arxiv, this step requires calcination at 550 degrees Celsius for 48 hours to allow the mixture to react and form copper phosphide crystals.

During the process, you only need to stabilize the temperature of the vacuum furnace, and no other operations are required.

This is simply a piece of cake for today’s materials and equipment that are already controlled by various computers. Therefore, they had plenty of time to chat and relax during the experiment.

"I heard that Professor Xu from China has completed the simulation calculation of KL-66 material? Does it mean that it is just a strong magnetic material?"

While drinking coffee, Hornby Eden looked at his colleagues and asked.

Speaking of this, the colleague nodded and said: "Well, the relevant papers have 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 at room temperature. There’s little hope for superconductors.”

"If I remember correctly, Professor Xu seems to be a mathematician, right?" Hornby Eden asked after thinking for a moment.

Hearing this, colleague Burne 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. Design Master, wait.”

"Don't forget, he personally developed the high-temperature copper-carbon-silver composite superconducting material. I heard that his original purpose of developing high-temperature superconducting materials was for controllable nuclear fusion technology."

"It's incredible. Mathematics, physics, astronomy, materials, and controllable nuclear fusion technology have also been solved. Has the cross-field effect lost its effect on him?" Hornby Eden exclaimed, shaking his head exaggeratedly.

"Who knows, this is probably another Newton-Gauss level monster." Burne Jones said with a smile.

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

"Let alone whether room temperature superconductivity can be achieved so easily, there are "false news" about room temperature superconductivity 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 has not taken off yet, and it was slapped away by Professor Xu."

There is nothing wrong with what Burne Jones said.

If it is based on the events of room temperature superconducting materials that have appeared every year in history, the related heat will at least last for at least ten days and a half months.

Then during this period, the stock market related to superconducting materials will surge and then slide.

Capital will cut a wave of leeks, and even cooperate personally when necessary, such as getting a replica experimental data to prove that this material is very likely to have room temperature superconductivity, and harvesting repeatedly.

However, this year, before they could take action, they were slapped away.

Even if the replica experiment is still in progress, no one can be sure whether this KL-66 superconducting material has superconducting properties, but the stock market has not risen as much as before.

There is no way, the name "Xu Chuan" is too famous.

Although it is just some speculative calculations, judging from the mathematical ability of this big man, there is basically no problem with his calculations.

After all, this is a Fields Medal winner, a super-powerful man who has solved two millennium problems.

This also caused the superconducting material sector, which should have been extremely hot, to be as calm as a pool of stagnant water, and even fell slightly.

Xu Chuan didn't care too much about these.

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

At this time, he was in the laboratory, personally conducting superconductivity tests on the reproduced KL-66 material.

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

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

Three sets of reproduction experiments, three copies of KL-66 materials were completely reproduced according to the paper.

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

For him, superconducting testing of superconducting materials is a familiar field.

The most important indicator to see whether a material is a superconducting material is whether it has the "Meissner effect", and the first thing he did was naturally this.

Unfortunately, after several attempts, Xu Chuan was convinced that the KL-66 material he was assigned did not have the Meissner effect.

There is no doubt that the first replication experiment failed.

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

Finally, it was confirmed that the material in his hand had a certain degree of anti-magnetism, but it was quite weak.

As for resistance, when the temperature was lowered several times for testing, it was found that when it was 250K (about -23℃), the resistivity dropped sharply, but it did not drop to zero.

At 7.1K, the resistance of the material will drop rapidly again, approaching zero resistance.

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

At room temperature, it cannot show superconductivity. Only when the temperature drops to 7.1K, it will show superconducting properties.

However, this is meaningless. There are many materials that can achieve superconductivity at 7.1K. And in this material, the superconducting critical temperature of lead is -265.95℃ (7.2K)

In this case, it is hard not to doubt whether 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.

If we only look at the material in his hand, the hope that KL-66 material is a room temperature superconductor has been shattered, which also made him sigh.

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

There are many accidental factors. If you need to ensure that there is no error in the replication experiment, at least three or more groups of controls should be done.

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

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

The three KL-66 materials reproduced according to the standard process all do not have the Meissner effect.

However, what surprised Xu Chuan was that the material numbered "No. 2" showed a similar anti-magnetic semi-suspension effect as the video released by South Korea.

Although subsequent tests confirmed that this was just a kind of anti-magnetism, it still attracted his attention.

If the mechanism of this anti-magnetism can be found, there may be some other discoveries.

On the other side, in the laboratory, looking at the test report in his hand, Fan Pengyue smiled and said: "It seems that this time I can give those South Korean netizens a good slap in the face."

The three groups of materials made by different people did not detect the Meissner effect. It can be said that the possibility of this KL-66 material being a room-temperature superconductor has been reduced to the extreme.

"Slap in the face? What's going on?" Chai Su, another researcher doing superconducting testing in the laboratory, asked curiously.

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

"Then the people in South Korea became dissatisfied, expressing their dissatisfaction and swearing at others."

"It's okay if they curse on the Internet in their own country, and they come to our country. If you don't believe it, open your scarf and use beta software to take a look. Now it's become an online controversy."

"Some people support our boss, and some people support the other party. There are even more people who want to win."

"Anyway, the topic of room-temperature superconducting materials is quite lively now."

Hearing this, Chai Su couldn't help but frown and asked: "No, I just want to know, judging from the calculated results, what's wrong with this? Are you still swearing?"

Fan Pengyue said with a smile: "It's normal. The old traditions in South Korea are also the old habits over there."

"After all, our relationship with South Korea is more 'delicate', and we look down on each other. In addition, some extreme groups there are crazy, can't tolerate sand in their eyes, and 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 his scarf, and searched for topics related to KL-66.

[Axi, what are you talking about? 】

[You must be envious of our room-temperature superconducting materials, so you are jealous and slandering them? 】

[It’s just a simulation calculation result. We have actually conducted superconducting tests. The magnet can be stably suspended on the KL-66 superconducting material. Isn’t this much more powerful than the so-called calculation? 】

[I very much doubt that Professor Xu did this to preserve the status of high-temperature superconducting materials in his hands. After all, once our KL-66 comes out, no one will buy its materials in the future. 】

You can indeed see some ‘familiar’ words under some popular videos of scarves.

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

When it comes to trolling, there is probably no other country where netizens are as capable as the Chinese.

"Send me the electronic versions of these three replica experiment reports."

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

Opposite him, Senior Brother Fan Pengyue smiled and nodded in response.

There's something good to watch again this time.

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

Going to other countries to rant about a different opinion is probably something only people from that country can do.

If it were other scholars, they would probably ignore this news.

But if it were his boss, it would be fine if he didn't see it. Now that he has seen it, it would be out of character for him not to respond after the results come out.

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

He couldn't help but feel happy thinking about the expressions on the faces of those South Koreans who trolled the Communist Party of China online after seeing these three replica experimental reports.

Who do you think it is bad for you to spray? Come and spray this guy.

The most important thing is how many times have you falsified your knowledge in the scientific field? Don’t you have any idea?

In 2005, the "research results of embryonic stem cells", known as one of the three major academic frauds in the world, were purely intentional fabrications.

In 2015, the "biggest fraud case" in academia also occurred in South Korea. At that time, nearly two hundred professors were brought to court.

What, how long has it been? Will the scar be healed and the pain forgotten?
