Chapter 343: What is it like to have a perverted boss?
Shaking his head, Song Wenbo 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 rested for a while and regained some energy before walking over.
Although testing superconducting materials is tedious, it is not very complicated.
After all, all kinds of experimental equipment are now fully automated or semi-automated.
For example, here at the Chuanhai Materials Laboratory, there is a complete superconducting electromagnetic testing system in the laboratory.
This system consists of instruments for measuring TC critical temperature and resistance value, Midas effect measurement equipment, computers, cay sensors and other equipment. It can test superconducting materials and reduce the experimental temperature to about 10K.
Of course, it can only test some basic key data of superconducting materials, such as resistance value, magnetic flux, etc. As for analyzing the fine structure, crystal structure, characterization structure, etc. of superconducting materials, additional equipment is needed.
Under the control of Song Wenbo, various equipment of the superconducting electromagnetic testing system began to operate, and the computers connected to these equipment projected the relevant data in real time.
The huge display screen is divided into four parts according to the y-axis, each showing different data.
Resistance information values, temperature control system values, magnetic field index values, AC magnetic susceptibility and other data for testing the main properties of superconducting materials are displayed.
As the prepared copper-carbon-silver composite material is placed into the superconducting electromagnetic testing equipment, the program set on the computer begins to run.
Liquid nitrogen as low as minus 196c began to be slowly injected into the cooling equipment, rapidly reducing the temperature of the measurement space.
0c,-0c,-100c.
Soon, the temperature in the measurement space quickly dropped to below minus one hundred degrees.
As the temperature decreases, the parameter curves such as resistance, temperature control, and magnetic field indicators also begin to fluctuate on the computer's display screen.
The resistance curve begins to slowly decline, all the way down from 1.910^-8Ω·m.
Looking at the slowly decreasing resistance value in front of him, Song Wenbai couldn't help but swallow.
The words Xu Chuan just said reappeared in his mind uncontrollably.
The critical tc is reached around 1k.
Is this really possible?
Looking at the temperature control data on the display screen, under the rapid freezing of liquid nitrogen, the temperature in the superconducting electromagnetic testing space has dropped to minus 110 degrees Celsius.
This temperature, converted into K degrees, has reached 163.1k. As long as it drops by another 10k, it can reach 1k.
Is it really possible? Inexplicably, a glimmer of expectation arose in his heart.
Involuntarily, Song Wenbai held his breath and stared at the screen.
The temperature drop from 163.1k to 1k does not take long for a superconducting electromagnetic testing system that uses liquid nitrogen as the refrigerant.
After all, the temperature of liquid nitrogen itself reaches -196 degrees Celsius, which is almost 77k, which is still a long way from the limit of its cooling.
On the display screen, the temperature control data decreased bit by bit, and Xu Chuan also looked at the data with bated breath.
1k is the critical TC data he calculated. If it can be successful, it can really be said to open up a whole new world for high-temperature superconducting materials.
But whether he can succeed, to be honest, he is not very confident in his heart.
After all, this breakthrough can be said to break the previous way of material research, which uses superconducting mechanism data to simulate the structure of superconducting materials and then prepares them 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 1k, the resistance curve still does not change much, and the resistance curve still maintains a steady decrease.
However, just the next second.
A miracle happened!
When the data on the display jumped to 13k, it originally maintained a smooth downward curve, and it hit the bottom at an angle of nearly 90 degrees as if jumping off a cliff.
Song Wenbai, who was squatting in front of the screen and concentrating on holding his breath tightly, saw this scene and his pupils suddenly shrank.
"The resistance is really zero?"
Looking at the curve that looked like a disconnected electrocardiogram, his heartbeat seemed to have stopped at this moment.
Staring at the screen blankly, Song Wenbo felt like he couldn't breathe at this moment.
"How can it be?"
"How can this be!"
"At a temperature of 1k, 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 film material in the superconducting electromagnetic testing system was just a normally conductive material, but in the next second, it had completed its transformation.
At a low temperature of 1K, it successfully achieved the transition to a zero-resistance superconducting state.
Looking at the data on the display screen, Xu Chuan's eyes were deep and distant, as if he wanted to see directly through the void the copper-carbon-silver composite film material in the superconducting electromagnetic testing space.
There, under the stimulation of a temperature of 1K, the small thin film atoms quickly reorganized the array and formed a new crystal structure as if the army had received instructions.
At this moment, nothing is lost in the current passing through it.
Clearly, this is what he's been looking for!
Although the temperature of 1k is not considered a high temperature, it can even be said to be extremely low.
But in the history of the development of superconducting materials, relatively speaking, there is no doubt that this is an amazing achievement!
In the laboratory, Song Wenbo couldn't care less 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 recovered and asked with difficulty: "How on earth did you do that?"
1k high-temperature superconducting material is already an amazing achievement in itself.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! Since scientists discovered the property of superconductivity in the last century, the research on superconductors in the materials world has never stopped.
But to this day, I have never heard of any country, laboratory or research institute that can achieve 1k high-temperature and normal-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 German Max Planck Institute of Chemistry, which can superconduct at minus 23 degrees Celsius, it cannot be maintained under normal pressure.
It can maintain superconducting at minus 23 degrees Celsius under an ultra-high pressure of 170 gpa.
Such harsh conditions can be said to make this material without any other practical value apart from its research value.
Even the pressure at the bottom of the Mariana Trench is only 1,100 atmospheres, and 170gpa is 1.7 million standard atmospheres.
Such high pressure has almost no practical value except in the laboratory.
But in contrast, the material he is now testing with his own hands is under standard atmospheric pressure.
Normal pressure 1k superconductivity, once this parameter is announced, will definitely set off huge waves in the world of superconducting materials.
What shocked him even more was that this person accurately predicted the critical TC temperature of this copper-carbon-silver composite material before starting the test.
This means that this person has clearly mastered the data of this superconducting material.
If he hadn't personally worked on the material in the laboratory and watched it being made bit by bit, he would have felt that the material had been taken from somewhere else and had 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:
"This is not very difficult. If you can understand the superconducting mechanism of high-temperature superconducting materials, plus a little mathematical ability and understanding of the material itself, you can also do it."
Hearing this, Song Wenbo was stunned for a moment, and then his pupils condensed to a point again. What did he hear? The superconducting mechanism of high-temperature superconducting materials?
Unable to help but swallow the air, he asked with a dry mouth: "Have you found the superconducting mechanism of high-temperature superconductors?"
Xu Chuan smiled and said: "I have to thank you for this. The low-temperature copper-carbon-silver composite material you previously developed provided me with some inspiration and ideas."
"Based on those experimental data, I expanded some ideas and theories, and used the laboratory model to make some optimizations for copper-carbon-silver composite materials."
"Anyway, you were of great help."
Hearing this, Song Wenbo's heartbeat stopped. He quickly asked: "Are you saying that the superconducting mechanism of high-temperature superconductors was developed by geniuses like you?"
Xu Chuan nodded and said: "Theoretically, yes, but I have also studied superconducting materials before. Are there any problems?"
Hearing this, Song Wenbai swallowed air again.
What is the problem?
The problem is big, okay!
If he remembered correctly, it should not have been more than fifteen days since this person obtained his previous data on low-temperature copper-carbon-silver superconducting materials.
In other words, in less than half a month, he figured out the superconducting mechanism that had not been clearly studied in the superconducting material community for half a century!
More importantly, he also used this mechanism and the mathematical model of the Chuanhai Materials Laboratory to re-complete the design of high-temperature copper-carbon-silver high-temperature superconducting materials!
And it’s even made!
What kind of perversion is this?
Nobel Prize Will Fields be able to solve problems that others have been unable to solve for half a century?
Or is this the world of genius?
Casual performance and research are the key points that others cannot look up to?
Thousands of thoughts went through his mind in an instant. Song Wenbo came back to his senses, took a deep breath, and couldn't help but ask: "Can I read the paper on the superconducting mechanism of high-temperature superconductors?"
Regarding the superconducting mechanism of high-temperature superconducting materials, it can be said that no one who studies superconducting materials, or even any researcher or scholar in the materials industry, can resist rejecting it. He is no exception.
Xu Chuan smiled and said: "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 with me. 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 and rest after tidying up the laboratory. Tomorrow you will lead people to continue to complete the performance testing of copper-carbon-silver composite high-temperature superconducting materials."
"I still need to go back and sort out some things, so I'll leave this to you."
Hearing this, Song Wenbai looked at Xu Chuan excitedly, nodded vigorously, and said: "Don't worry, boss, I will definitely handle this matter."
Xu Chuan smiled, turned and left the laboratory.
Late at night, in the small Hongqi car, Zheng Hai looked at Xu Chuan who got into the car with a smile, and asked: "I thought you would live here today like yesterday."
Xu Chuan smiled and said: "The experiment is over and it's over for now. There is no need to live here anymore. You still have to be comfortable at home."
Hearing this, Zheng Hai also smiled. He didn't ask any more questions, started the car and drove into the distance.
He did not ask whether the experiment was successful or what Xu Chuan was doing.
He only needs to do his own thing well, and as for other things, those are beyond his control.
After returning to the villa smoothly, Xu Chuan first took a hot bath, then wiped his hair and sat in front of the computer.
Although it was already late at night and early in the morning, he still had more important things to do than sleep.
After opening the superconducting mechanism theory paper he had completed two days ago, Xu Chuan began to make some modifications on it.
By completing an experiment with your own hands, you will gain far more than by looking at other people's experimental data.
Sometimes, theoretical research and applied experiments do not conflict, and even complement each other.
The 1k 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, in the past, it was generally believed that excessive doping would cause the critical tc of high-temperature superconductors to decrease. However, today, he discovered that excessively doped copper-carbon-silver high-temperature superconductors achieved high-temperature superconductivity of 1k.
Although 1k is not considered a high temperature, and although he can calculate the function between doping data and superconducting energy gap through models, he has not yet used a theory to explain the impact of doping on superconductors.
figure out.
Or how the strong electron correlation effect in high-temperature superconductors can sense the effect of external electromagnetic fields in a coordinated manner in the manner of de Broglie waves, just like the aharonov-bohm effect of charged particles, thereby transforming the insignificant wave-particle duality of a single electron into
magnified to the macro scale.
These are in-depth questions that need to be studied by him and other researchers.
Of course, this is not a temporary achievement, it will take a long time, countless experiments, and countless theoretical revisions to complete.
