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 the KL-66 material.
His judgment on the KL-66 material, at this point where the flow of room-temperature superconductors 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 such 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 as real. Before the reproduction results come out, and under the current situation where there is no 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. There is no problem in expressing his views after the results of the replica experiment come out. ]
【???The God of Sichuan can't even express his opinions, 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
on arxiv.]
[Outrageous, to be arrogant, I’m afraid you can’t even understand the paper uploaded by Sichuan God, but you already know a lot of 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, loves 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 also very 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 re-engraving results come out, few researchers in the materials field come forward to express their opinions and views.
After all, it would be quite embarrassing to be slapped in the face.
Of course, for someone like Professor Xu who has done simulation calculations and then expresses his own opinions and opinions, there is no problem at all.
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 field of materials was that he moved so fast.
It seems that within three days of the KL-66 material-related papers being posted on arxiv, the targeted formation energy calculations, phonon spectra, and tight-binding model results were 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 various materials and equipment controlled by computer intelligence. Therefore, they have 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.
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-Gaussian 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."
"Not to mention whether room temperature superconductivity can be realized so easily, there are 'false news' released about room temperature superconductivity almost every year, and then the stock market cuts off a wave of leeks, and slowly the news disappears.
It cannot be proven or disproven.”
"But the difference this year is that before the stock market took off, it was slapped down by Professor Xu."
There is nothing wrong with what Burne-Jones said.
If we look at the normal-temperature superconducting material events that have occurred every year in history, the related heat will last for at least ten days and a half.
This chapter is not over yet, please click on the next page to continue reading! During this period, the stock market related to superconducting materials will surge and then fall.
Capital is cutting a wave of leeks in it, and will even personally cooperate when necessary, such as obtaining replica experimental data to prove that this material is likely to have room temperature superconductivity, and harvesting it over and over again.
However, before they could take action this year, they were slapped and killed.
Even though the re-engraving 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 experienced any growth as in the past.
There is no way, the reputation of the name 'Xuchuan' is too great.
Although they are just some speculative calculations, judging from the mathematical ability of this big man, it is basically impossible for there to be any problems with his calculations.
After all, this is a Fields Medal winner, a super-powerful man who has personally solved two millennium problems.
This has also resulted in the superconducting material sector, which was originally supposed to be extremely hot, now as calm as a pool of stagnant water, and even falling slightly.
Xu Chuan didn't pay much attention to this.
He didn't even know that some capitalists' dreams of cutting leeks were shattered because of his opinions in class.
At this moment, he is in the laboratory, personally conducting superconducting tests on the replica KL-66 material.
Although from the perspective of material calculations, the probability that KL-66 is a room temperature superconductor is already very small, 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 stimulating to see a way to break the existing materials research and development system.
.......
Three sets of reproduction experiments were carried out, and three copies of KL-66 material were reproduced completely according to the paper.
Among the three materials, Xu Chuan personally verified one, and the other two were handed over to two researchers in the field of superconducting materials.
Conducting superconducting tests on superconducting materials is a familiar and unfamiliar field for him.
When looking at whether a material is a superconducting material, the core indicator is whether it has the 'Meissner effect'. The first thing he did was naturally this.
Unfortunately, after going back and forth several times, Xu Chuan was convinced that the KL-66 material he was assigned to reproduce did not have the Meissner effect.
There is no doubt that the first reproduction experiment was a failure.
Of course, he did not just give up and deny it. In the following time, he successively conducted tests on the synthesized material in terms of magnetic field, resistance, critical temperature and other aspects.
It was finally confirmed that the material in his hand had certain diamagnetic properties, but it was quite weak.
As for the resistance, when the temperature was lowered several times for testing, it was found that at 250K (about -23°C), the resistivity dropped sharply, but the drop was less than zero.
At 7.1K, the resistance of the material will drop rapidly again, reaching almost zero resistance.
This result is basically consistent with the test of KL-66 conducted by the computational material model.
At room temperature, it cannot show superconductivity. It will only show superconducting properties when the temperature drops to 7.1K.
However, this is meaningless. There are many materials that can achieve superconducting properties at a temperature of 7.1K. And in this material, the superconducting critical temperature of lead is -265.95℃ (7.2K)
In this case, it is difficult not to wonder whether this critical temperature transition is caused by 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 hands alone, the hope that the KL-66 material could be a room-temperature superconductor had been shattered, which also made him sigh.
However, verifying a material cannot be completed in one replicate experiment.
There are many accidental factors. If you need to ensure that there is no error in the replica experiment, at least three or more sets of controls must be done.
After waiting for a while, the other two sets of test results also came out.
Judging from the test results, all observations of the Meissner effect have failed.
None of the three KL-66 materials reproduced according to the standard process have the Meissner effect.
However, what surprised Xu Chuan was that the material numbered 'No. 2' showed a diamagnetic semi-levitation effect similar to the video from South Korea.
Although subsequent tests confirmed that this was just a form of diamagnetism, it still caught his attention.
If the mechanism of this diamagnetism can be found, perhaps there will 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 those South Korean netizens in the face."
In three groups of materials made by different people, the Meissner effect was not detected in any of them. 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 were dissatisfied, and they expressed their dissatisfaction and cursed people."
"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 the scarf and use beta software to take a look. Now it has 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."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "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 and have ugly eyes.
It doesn't like sand and likes to chase and bite people."
Hearing this, Xu Chuan, who was reading the test report, took a curious look, then took out his cell 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 are 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 his materials in the future.]
You can indeed see some "familiar" words under some popular videos of scarves.
However, these words were basically sprayed down 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 me, Senior Brother Fan Pengyue smiled and nodded in response.
There's another good show to watch 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, if he doesn't respond after the results come out, it's not his character.
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 on the Internet after seeing these three replica experimental reports.
Who do you think is bad for you to troll? Come and troll this person.
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 'embryonic stem cell research results', known as one of the world's three major academic frauds, was purely intentionally fabricated.
In 2015, the "biggest fraud case" in academia also occurred in South Korea, and nearly two hundred professors were brought to court at that time.
Why, how long has it been since? Has the scar healed and the pain forgotten?
