Great Country Academician

Shaking his head, Song Wenbai put aside the distracting thoughts in his mind, and began to use the equipment in the laboratory to test the silver-gray copper-carbon-silver composite material in the vessel.

On the side, Xu Chuan also walked over after resting for a while and recovering some energy.

Testing superconducting materials is tedious, but not complicated.

After all, all kinds of experimental equipment are basically fully automatic or semi-automatic nowadays.

For example, Chuanhai Materials Laboratory has a complete set of superconducting electromagnetic testing system in the laboratory.

This system is composed of instruments for measuring Tc critical temperature and resistance value, Midas effect measuring equipment, computer, CASSY sensor and other equipment. It can test superconducting materials and can reduce the experimental temperature to about 10K.

Of course, it is only able to test some basic key data of superconducting materials, such as resistance value, magnetic flux and so on. As for the analysis of the fine structure, crystal structure, and characterization structure of superconducting materials, additional equipment is needed.

Under the control of Song Wenbai, the various equipment of the superconducting electromagnetic testing system began to operate, and the computer connected to these equipment projected the relevant data in real time.

The huge display screen is divided into four parts according to the XY axis, each displaying different data.

The data for testing the main properties of superconducting materials, such as resistance information value, temperature control system value, magnetic field index value, and AC magnetic susceptibility, are all displayed.

As the prepared copper-carbon-silver composite material was put into the superconducting electromagnetic testing equipment, the program set on the computer began to run.

Liquid nitrogen as low as minus 196°C began to be slowly injected into the cooling equipment, rapidly reducing the temperature of the measurement space.

0℃, -50℃, -100℃.

Soon, the temperature in the measurement space dropped to below minus one hundred degrees.

As the temperature dropped, the parameter curves of resistance, temperature control, and magnetic field indicators on the computer's display screen also began to fluctuate.

The resistance curve began to decline slowly, from 1.95x10^(-8)Ω·m all the way down.

Looking at the slowly decreasing resistance value in front of him, Song Wenbo couldn't help swallowing.

What Xu Chuan just said resurfaced in his mind involuntarily.

The critical Tc is reached around 152K.

Is this really possible?

Looking at the temperature control data on the display, under the rapid freezing of liquid nitrogen, the temperature in the superconducting electromagnetic test space has dropped to minus 110°C.

This temperature, converted into K degrees, has reached 163.15K. As long as it drops by 10K, it can be delivered to 152K.

Is it really possible? Inexplicably, a glimmer of anticipation rose in his heart.

Involuntarily, Song Wenbai held his breath and stared at the screen tightly.

The temperature drop from 163.15K to 152K does not take long for a superconducting electromagnetic test system that uses liquid nitrogen as a refrigerant.

After all, the temperature of liquid nitrogen itself has reached -196 degrees Celsius, which is almost 77K, which is still a long way from the limit it can cool.

On the display screen, the temperature control data decreased bit by bit, and Xu Chuan also looked at the data with bated breath.

152K is the critical Tc data he calculated. If it can be successful, it can really be said that it will open up a whole new world for high-temperature superconducting materials.

But whether he can succeed, to be honest, he doesn't have enough confidence in his heart.

After all, this kind of breakthrough can be said to have broken the way of material research in the past. The structure of superconducting materials is simulated through superconducting mechanism data, and then prepared through experiments.

This is a route that can be said to be almost completely different from traditional materials research.

As the temperature control data decreases, when the data on the display jumps to 155K, the resistance curve still does not change much, and the resistance curve still maintains a steady decrease.

However, in the next second.

A miracle happened!

When the data on the display jumps to 153K, it maintains a steady downward curve, and hits the bottom directly at an angle of nearly 90 degrees as if jumping off a cliff.

Crouching in front of the monitor, Song Wenbai, who was concentrating and holding his breath tightly, saw this scene, his pupils suddenly shrank.

"Resistance, is it really zero?"

Looking at the curve like a broken line in the electrocardiogram, his heartbeat seemed to stop at this moment.

Staring blankly at the screen, Song Wenbo felt that he could not breathe.

"How can it be?"

"How can this be!"

"At a temperature of 152K, does it really transform into a superconducting state?"

After muttering a few words to himself, he suddenly realized something, and suddenly turned his head to look at the figure standing behind him.

At this moment, Xu Chuan also had a smile on his face and eyes.

Yes, he succeeded!

In the first second, the copper-carbon-silver composite thin film material in the superconducting electromagnetic test system was just a normal conductive material, but in the second second, it has completed the transformation.

At a low temperature of 152K, it successfully achieved the transformation of zero-resistance superconducting state.

Looking at the data on the display screen, Xu Chuan's eyes were deep and far away, as if he wanted to directly see the copper-carbon-silver composite film material in the superconducting electromagnetic test space through the void.

There, under the stimulation of a temperature of 152K, the atoms in that small thin film quickly rearranged the array as if the army had received an order, forming a brand new crystal structure.

At this moment, with the current passing through it, nothing is lost.

Clearly, this is what he's been looking for!

Although the temperature of 152K is not a high temperature, it can even be said to be extremely low.

But in the history of the development of superconducting materials, relatively speaking, this is undoubtedly an amazing achievement!

In the laboratory, Song Wenbo didn't care about the surprise that the resistance of the copper-carbon-silver high-temperature superconducting material was zero. He looked at Xu Chuan in horror, as if he was looking at a monster.

After a while, he slowed down and asked with difficulty: "How did you do it?"

The 152K high-temperature superconducting material itself is already an amazing achievement.

Since scientists discovered the characteristic of superconductivity in the last century, the research on superconductors in the material world has never stopped.

But until now, I have never heard of any country, any laboratory or research institute that can achieve 152K high-temperature and atmospheric-pressure superconductivity.

It itself has broken the historical record of high-temperature overpressure superconducting materials.

As for the iron-based high-temperature superconducting material studied by the Max Planck Institute of Chemistry in Germany, which can superconduct at minus 23 degrees Celsius, it is not maintained at normal pressure.

It is under the ultra-high pressure of 170Gpa to maintain superconductivity at minus 23 degrees Celsius.

Such harsh conditions can be said to make this material have no practical value other than research value.

Even the pressure at the bottom of the Mariana Trench is only 1100 atmospheres, and 170Gpa is 1.7 million standard atmospheres.

Such a high pressure has almost no practical value except for the laboratory.

But in contrast, the material he is currently experimenting with is under standard atmospheric pressure.

Atmospheric pressure 152K superconductivity, the announcement of this parameter will definitely set off a huge wave in the field of superconducting materials.

What shocked him even more was that this man accurately predicted the critical Tc temperature of the copper-carbon-silver composite material before starting the test.

This means that this person has clearly grasped the data of this superconducting material.

If he hadn't personally worked in the laboratory and watched the material being made bit by bit, he would definitely feel that the material was taken from other places and had already been tested.

Otherwise, how is it possible to know the superconducting critical Tc without testing?

Hearing Song Wenbai's question, Xu Chuan withdrew his gaze from the computer screen, glanced at him, and said with a smile:

"It's not very difficult, and if you know the superconducting mechanism of high-temperature superconducting materials, plus a little bit of mathematical ability and understanding of the materials themselves, it can also be done."

Hearing this, Song Wenbai froze for a moment, then his pupils condensed into one point again, what did he hear? Superconducting mechanism of high temperature superconducting materials?

Unable to swallow the air, he asked dryly, "Have you found the superconducting mechanism of high-temperature superconductors?"

Xu Chuan smiled and said, "I have to thank you. The low-temperature copper-carbon-silver composite material you researched before gave me some inspiration and ideas."

"On those experimental data, I expanded some ideas and theories, and used the laboratory model to optimize the copper-carbon-silver composite material."

"Anyway, you've been a great help."

Hearing this, Song Wenbai's heart skipped a beat, and he quickly asked, "You mean, the superconducting mechanism of high-temperature superconductors was researched by geniuses like you?"

Xu Chuan nodded and said, "Theoretically, yes, but I have also studied superconducting materials before. Is there any problem?"

Hearing this, Song Wenbai swallowed again.

What is the problem?

Big problem, okay!

If he remembers correctly, it should not have been more than fifteen days since this man obtained the data of his previous low-temperature copper-carbon-silver superconducting material.

In other words, in less than half a month, he figured out the superconducting mechanism that the superconducting material field has not studied clearly for half a century!

More importantly, he also used this mechanism + the mathematical model of Chuanhai Materials Laboratory to re-complete the design of high-temperature copper-carbon-silver high-temperature superconducting materials!

And it's done!

What kind of pervert is this?

Will the Nobel Prize + Fields will be able to do whatever they want to solve problems that others have been unable to solve for half a century?

Or is this the world of geniuses?

Playing and researching casually is the key point that others can't look up to?

Thousands of thoughts flashed through his mind, and Song Wenbo came back to his senses, took a deep breath, and couldn't help but ask, "Can I read the superconducting theory paper on high-temperature superconductors?"

Regarding the superconducting mechanism of high-temperature superconducting materials, it can be said that no researcher or scholar who studies superconducting materials, or even any researcher or scholar in the material industry, can resist rejection. He is also included.

Xu Chuan said with a smile: "The core point of the superconducting mechanism of high-temperature superconducting materials lies in the 'strong electron correlation' effect, but I didn't bring the paper. If you want to read it, I can send you a copy tomorrow."

After a pause, he continued: "It's getting late today, let's go back to rest after tidying up the laboratory. Tomorrow you will take someone to complete the performance test of the copper-carbon-silver composite high-temperature superconducting material."

"I still need to go back and organize some things, and I will leave it to you here."

Hearing this, Song Wenbai looked at Xu Chuan excitedly, nodded vigorously, and said, "Don't worry, boss, I will definitely handle this matter well."

Xu Chuan smiled, turned and left the laboratory.

In the middle of the night, in the small red flag car, Zheng Hai looked at Xu Chuan who got into the car with a smile, and asked, "I thought you would live here today as you did yesterday."

Xu Chuan smiled and said: "The experiment is over, and it's over for now. There's no need to live here anymore. It's still comfortable to live at home."

Hearing this, Zheng Hai also smiled, he didn't ask any more questions, and started the car to drive away.

He didn't ask if the experiment was successful, nor did he ask what Xu Chuan was doing.

He only needs to do his own thing well, as for the others, those are beyond his control.

After returning to the villa smoothly, Xu Chuan took a hot bath first, then wiped his hair and sat down in front of the computer.

Although it was late at night and early in the morning, he still had more important things to do than sleep.

After opening the superconducting machine theory paper completed two days ago, Xu Chuan began to make some modifications on it.

Complete an experiment by yourself, and you will gain far more than looking at other people's experimental data.

Sometimes, theoretical research and applied experiments do not conflict, and even complement each other.

The 152K copper-carbon-silver high-temperature superconductor contains the superconducting mechanism of high-temperature superconducting materials. Although he already knows the basic principle, behind this principle, there are more and more profound theoretical work waiting for him to complete.

For example, why in the past, it was generally believed that excessive doping would lead to a decrease in the critical Tc of high-temperature superconductors, but today, he discovered that excessively doped copper-carbon-silver high-temperature superconductors have achieved high-temperature superconductivity at 152K.

Although 152K is not considered a high temperature, and although he can use the model to calculate the function between the doping data and the superconducting energy gap, the effect of doping on superconductors, what kind of theory should be used to explain it, he has not yet figure out.

Or, the strong electron correlation effect in the high-temperature superconductor is how to feel the effect of the external electromagnetic field in the way of De Broglie wave in unison, just like the Aharonov-Bohm effect of charged particles, so that the negligible wave-particle duality of a single electron magnified to a macroscopic scale.

These are deeper questions that need to be studied by him, as well as by other researchers.

Of course, this is not a one-time achievement. It will take a long time, countless experiments, and countless theoretical revisions to complete.
