The fingernail-sized piece of material obtained now can be said to be the hope of the entire project team. As Xu Yuan made the decision to conduct superconducting tests, the process was watched by everyone on the scene.

soon.

One of the professors of materials science at Yanda University carefully placed the gray material on the test bench.

Everyone couldn't help but hold their breath, looking forward to what would happen next.

Before officially starting the test, the professor did not forget to look up at Xu Yuan next to him again.

"Xu Yuan."

"The Meiners Effect experiment is ready."

"Let's start." Xu Yuan nodded and said, his calm face showing full confidence.

The so-called Midas effect is that when a superconducting material is placed in a magnetic field, it can be observed that the magnetic field lines cannot invade.

This phenomenon of excluding magnetic lines of force is also called magnetoresistance effect.

Placing superconducting materials on top of magnets can cause them to levitate, an experiment that confirms the Meissner effect.

When the professor who was conducting the experiment heard Xu Yuan's words, he naturally did not waste any more time.

First, lower the temperature using liquid nitrogen, then turn on the magnetic field.

At this moment, the temperature around the material is at absolute zero, which is more than 270 degrees below zero. However, under everyone's close attention, it can be seen that the gray material in the magnetic field does not show the so-called Meiners effect. It is completely static and no suspension can be seen.

However, everyone's expressions were extremely calm, and there was not even a perceptible change in facial expression.

Obviously this situation was expected.

They did not disband the project team and continued their research to overcome room-temperature superconducting materials.

The critical temperature of superconductivity must be around 300K.

Therefore, it is completely normal that materials do not have superconductivity at absolute zero.

in contrast.

If the material really experiences the Meiners effect at this time, it will disappoint everyone.

Because this only means that they have discovered a new low-temperature superconducting material.

Compared with room-temperature superconductors, its value and gold content are so low that people are not interested in it.

Although this discovery would be considered a relatively significant scientific research achievement if it were made in other materials laboratories overseas.

Xu Yuan was also looking at the superconducting material in the magnetic field. Faced with this situation, he just uttered a few words calmly and continued to carry out the subsequent experiments.

“Raise the temperature.”

"It's Dean Xu." The professor responded immediately after hearing this.

And in the next second, the device was controlled again, causing the temperature in the magnetic field to begin to show signs of rising.

It didn't take long for the temperature to rise from absolute zero to more than one hundred degrees below zero.

That is 140k.

Within this temperature range, everyone's nerves are once again aroused.

Compared to the adjustment process, I should look forward to it more.

no way.

In previous experiments, the best performance was that of high-temperature superconducting materials with a critical temperature recorded at 140K.

Even if this experiment still cannot reach the level of room-temperature superconducting materials, if this number can be increased further, it will be considered a new development in the research of superconducting materials.

At least all the hard work everyone has put in during this period will not be in vain.

And it seemed that the situation was developing as everyone expected. When the temperature of the magnetic field reached more than 140 degrees below zero, the fingernail-sized piece of material still did not float.

There wasn't even any sign of movement.

This means that perhaps a higher temperature is needed before this material can show its superconductivity.

This situation has also begun to make some people unable to help but discuss it, and the expectations are growing.

"The magnetic field temperature has exceeded 140K, and there is still no sign of the Meiners effect appearing. Perhaps we have discovered a new superconducting material with a higher critical temperature."

“It really brought us a surprise.”

"As expected of a superconducting material synthesized by Professor Xu himself, this performance is truly amazing!"

"Guess what the critical temperature of this material will be?"

"I believe in Dean Xu. The temperature can at least be above -100 degrees."

"Is it not possible to directly reach the room temperature superconducting level?"

“It’s so exciting!”

But there are also many people who are worried that the Meiners effect may not occur because the current material is not a superconducting material at all.

However, this thought did not remain in my mind for long before it was forcibly driven out of my mind.

Who made Xu Yuan create so many miracles?

Let everyone believe that as long as Xu Yuan is involved in and is responsible for a project, it will never fail in the end.

Perhaps the results of this experiment are still far from the room-temperature superconducting materials that everyone wants, but it is definitely not even a superconducting material. You know, before this Meiners effect experiment, they had already discovered several new superconducting materials.

But as time went by, everyone began to feel a little unsure.

Under the action of the temperature control equipment, the temperature in the magnetic field is rising at a rapid rate.

Soon the temperature passed minus 100 degrees and headed towards minus 90 degrees and minus 50 degrees.

It is about to reach room temperature.

However, during this process, the superconducting material in the magnetic field still did not show any changes.

Not to mention the Meiners effect, the material is suspended in the magnetic field.

There was hardly any movement.

No matter how you look at it, it looks like an ordinary material and does not have any superconducting properties at all.

But the experiment has already proceeded to this point, and no matter what the result is, we have no choice but to continue.

However, it is worth mentioning that the temperature in the magnetic field is increasing at a slightly slower rate than before. It seems that they are worried that the temperature in the magnetic field will change too quickly, which may make the Meiners effect less obvious.

After all, for some superconducting materials, the critical temperature value may be accurate to a certain degree.

If the temperature in the magnetic field changes too quickly, the Meiners effect of the material may disappear directly due to the temperature change before it has time to occur.

In the blink of an eye, several minutes passed.

Under everyone's gaze, it can be seen that the Kelvin has reached 273k.

It means the temperature has reached 0 degrees Celsius.

You have to know that a zero-degree environment is already considered room temperature for human living space.

But this piece of material the size of a fingernail still showed no signs of suspension.

The experiment has been carried out to this point, which is enough to illustrate some problems.

That is, this piece of material most likely does not have superconducting properties at all.

If someone looked at the professors present at this time, they would find that there was a hint of regret on their faces. It was obvious that they had never expected such an outcome.

Even the professor in charge of the experiment had no choice but to look at Xu Yuan again and ask:
"Xu Yuan."

"Do you want to continue the experiment?"

After these words were spoken, everyone else at the scene fell silent.

Based on the experience of superconducting material research, the Meiners experiment has indeed lost its meaning at this stage.

Continuing to increase the temperature would just be a waste of time.

Although everyone is reluctant to accept this fact, the reality is that instead of wasting time on failed materials, it is better to convert all of it into motivation to immediately conduct research on new materials.

It can only be said that although Xu Yuan has created many miracles in scientific research, he is not omnipotent after all.

Sometimes there will be failures.

But among those present, if we ask who trusts Xu Yuan the most, Zhang Jin's name will definitely be mentioned.

After all, the two of them had collaborated on projects in the field of materials a long time ago.

Xu Yuan’s performance at that time gave him too much shock.

It can even be said that it is beyond cognition.

In addition to the things that Xu Yuan participated in later, in his heart, Xu Yuan was the kind of talented scientist who was favored by everyone. No matter what kind of problem he encountered, he would turn decay into magic and give everyone a miracle.

He believes that the superconducting material this time is also not surprising.

Let’s not talk about the experimental situation for now, but just talk about the new superconducting materials discovered in previous experiments.

This proves that the research direction given by Xu Yuan is correct, otherwise there would not be so many results.

The material that is currently experiencing the Meiners effect is one of Xu Yuan's most important research directions. The experimental results should be even higher, and it should not be considered a superconducting material in any way.

Especially when I think about the efforts I have put into this during this period, I am even more reluctant to believe it.

So when the thought stayed here, when everyone was silent, Zhang Jin next to him suddenly spoke.

"Maybe there are some problems in the steps of the material synthesis process."

"So the structure of the synthesized material has changed."

"So the Meiners effect cannot occur, and the original superconducting properties are lost?"

From common sense analysis, Zhang Jin's guess is not groundless.

For special materials like superconducting materials, every step or small operation in the synthesis process is very important, otherwise any even small deviation will change the structure of the material itself, and its own characteristics will naturally no longer exist.

Perhaps the material developed by Xu Yuan is indeed a superconducting material, but its structure changed during the synthesis process.

This results in the inability to generate the Meiners effect.

If this is true, then the situation is not that complicated. It is nothing more than re-synthesizing the materials.

It just takes two more days to wait.

After listening to Zhang Jin's question, Xu Yuan of course understood that the other party was also considering himself and the materials.

But she made her own decision.

That is to maintain trust and continue to experiment with this material.

Almost the next second after Zhang Jin finished speaking, Xu Yuan opened his mouth and gave instructions to the professor again.

"Keep raising the temperature."

Although his expression didn't change much when he said this, his look still revealed a strong sense of confidence.

There is almost no change from before.

If someone else was responsible for the synthesis of this material, it might be possible that the material structure would change and lose its superconducting properties due to operational errors during the process. But it should be noted that the synthesis of the material placed in the magnetic field was completed by him and Zhang Jin.

There is no way I would make such a low-level mistake.

Therefore, Zhang Jin's speculation was completely untenable. Although the others around him expressed some regret, they would not question Xu Yuan's decision.

Anyway, continuing to increase the temperature in the magnetic field will only take more time to observe.

"It's Dean Xu."

The professor nodded upon hearing this, and immediately controlled the equipment to continue rising the temperature from zero degrees.

The Kelvin number keeps increasing.

274k.

278k.

……

292k.

As the Calvin number on the instrument continues to change, the material in the magnetic field remains motionless.

The Meiners effect never occurred.

This made everyone around feel increasingly depressed. Although they were very reluctant to see this happen, they had no choice but to accept the reality.

Even Zhang Jin, who had always believed in Xu Yuan, couldn't help but ask himself this question in his mind.

I can't believe that failure would happen in Xu Yuan's hands.

But because everyone's attention was on this material at the moment, no one noticed the change in Xu Yuan's expression next to him.

If you observe carefully, you will clearly find that the smile and confidence on his face have not decreased because of the current situation, but have increased a lot.

Even his lips moved slightly, and he suddenly muttered something to himself.

He uttered two words with some excitement in his heart.

"It's done."

Because at this moment, he suddenly noticed the progress bar on the panel that appeared in front of him.

Still reached 100 percent.

Such a substantial increase, especially at a time like this, can only mean one thing.

He successfully conquered room-temperature superconducting materials.

really.

Just when others wanted to give up, the Kelvin number displayed on the instrument just reached 300k.

And this temperature is exactly around 26 degrees, which is quite suitable.

The gray material that was originally in the magnetic field successfully floated above the magnetic field at this temperature. At this moment, the Meiners effect was fully presented in the sight of every professor present.

The spirit and emotions that were about to dissipate suddenly grew back again.

Many people even widened their eyes.

This caused shocked voices to be heard throughout the laboratory.

"Look, the material is really suspended, and the Meiners effect really appears."

"Oh my god, this is incredible."

"The Meiners effect really occurs, and the critical temperature is 300K. This is a true room-temperature superconducting material."

"We succeeded."

After absorbing the surprised sounds around him, Zhang Jin finally reacted soon.

He immediately turned his head to look at Xu Yuan beside him, and forced himself to suppress the joy and excitement in his heart, and there was even a tremor in his voice when he spoke.

"You must have known the result a long time ago, no wonder you insisted on continuing the experiment just now."

"I said that it's impossible for a project you're involved in to fail."

"Dean Zhang, what you said really puts me under a lot of pressure." Xu Yuan responded with a smile.

It is worth mentioning that all the project members present were professors of materials selected from Yanda and Qinghua. Naturally, they would not get carried away by the joy at the moment. Everyone was able to control their emotions well, calm themselves down quickly, and continue to devote themselves to their work.

After all, the current material has successfully produced the Meiners effect at a critical temperature of 300K.

However, to thoroughly prove that this is a room-temperature superconducting material, it is necessary to conduct Josephson effect and magnetic flux quantization experiments.

Everyone knows the value and significance of room-temperature superconducting materials, especially when the critical temperature is still 300K.

It is imperative to obtain all the data on this structural material as soon as possible.

At this point, Xu Yuan no longer needed to arrange anything, as the others would naturally complete the task with great care.

All that's left is to wait patiently.

Compared with the previous Meiners effect experiment, the next two experiments took significantly less time, because the critical temperature was already known, and the materials could be tested directly at room temperature.

There is no need to use temperature control equipment as before, just let the temperature in the magnetic field drop first.

By the way, if we knew that the critical temperature of this material is 300K, we wouldn't have needed liquid nitrogen just now.

The actual situation was basically as Xu Yuan had expected. Before long, the complete data report on this superconducting material was placed in front of Xu Yuan.

Xu Yuan naturally did not keep the secret and immediately picked up the report and opened it to read it carefully.

During this process, Zhang Jin couldn't help but stand nearby and report on the material situation at the same time.

"Based on the results of the Meiners effect experiment, the Josephson effect experiment and the magnetic flux quantization experiment, we can now determine that the superconducting properties of our material are most obvious at a critical temperature of 300K."

“And it’s not going to just disappear as temperatures rise.”

"This is the first room-temperature superconducting material discovered in my country and even in the world."

“It will be the most glorious day in the field of materials.”

As Zhang Jin finished speaking, thunderous applause suddenly broke out at the scene.

Everyone's face was filled with joy and excitement.

Looking back on the day when we decided to study room-temperature superconducting materials, many people thought that this was an impossible task.

Although it is possible to increase the temperature of high-temperature superconducting materials, it is simply a pipe dream to achieve room temperature.

The gap in between is really too big.

The reason why I am willing to stay in this project team and make my greatest contribution to it is not only because I believe in and admire Xu Yuan, but also because I want to take advantage of the opportunity to improve my own level.

After all, they had successfully developed new aerospace materials in just a few months.

This kind of opportunity is not available in other projects.

But no one expected that a few months later, room-temperature superconducting materials would appear so suddenly.

It's surprising and exciting, yet also caught off guard, and you even feel like you're dreaming.

After turning around and discovering that all this was real, a vision of the future large-scale application of room-temperature superconducting materials began to emerge in my mind.

First of all, relying on the zero resistance characteristics of room-temperature superconducting materials, it can effectively reduce losses in the process of power transportation, allowing society to better use clean energy.

In addition, room-temperature superconducting materials can also play a very important role in transportation and medical care.

There is also the research on quantum computers, which cannot be separated from superconducting materials.

Of course, the most critical thing is the controlled nuclear fusion device. The emergence of room-temperature superconducting materials can effectively accelerate the research on controlled nuclear fusion devices. You must know that this can change the entire world pattern.

Thinking of this, a new question arises.

In the end, Zhang Jin took the lead in proposing it.

"What should we do next? Should we announce to the outside world that we have successfully developed room-temperature superconducting materials?"

As soon as the words fell, the eyes of other people at the scene lit up, and they realized that this was something that needed to be discussed and decided.

As the world's first project team to conquer room-temperature superconducting materials, everyone knows what a huge impact and sensation it will cause if this news is announced to the outside world.

Not to mention the people's carnival and excitement, I'm afraid even other countries will be unable to sit still.

Because everyone knows that conquering room-temperature superconducting materials represents the rapid development of advanced science and technology.

This is definitely something that some people don't want to see.

Therefore, the decision on whether to announce the news still needs careful discussion and research.

Xu Yuan naturally understood the interests involved. After a little thought, he replied in a deep voice:
"Let's report this news to the headquarters first."

He did not forget that when he went to Bai Xinzhou to get the data, he said he would tell the other party as soon as possible.

At this moment, the other project members in the laboratory naturally had no objection to Xu Yuan's decision. After all, given the value of room-temperature superconducting materials, the final direction is no longer something they can decide.

……

Bai Xinzhou was supposed to go to the branch in Luyang to attend a meeting today, but just as he got in the car to go to the airport, he suddenly received a call from the Yanda Superconducting Materials Laboratory.

I learned last night that the Superconducting Materials Laboratory successfully developed room-temperature superconducting materials.

Faced with this news, the whole person was stunned for a moment.

The hand holding the phone froze in mid-air, obviously not expecting the news to come so quickly.

When he was looking for data for Xu Yuan before, he believed that Xu Yuan would definitely be able to research room-temperature superconducting materials. After all, with Xu Yuan's talent and strength, he had the best chance of success.

But he guessed that it might take several years.

Because everyone knows that the difficulty of researching and developing room-temperature superconducting materials is not something that new aerospace materials can match.

As a result, he heard something now. It turned out that room-temperature superconducting materials have been successfully conquered and have also undergone various superconducting experiments.

As various thoughts began to emerge in his mind, Bai Xinzhou found it difficult to control his inner joy and excitement.

So after hanging up the phone, he explained directly to the driver and assistant without any hesitation.

"Cancel all your schedule today and go to Yanda immediately."

"Okay, Dean." The assistant in the co-pilot seat nodded immediately after hearing this.

At the same time, the driver did not waste any time. He turned around at the intersection and drove towards Yanda.

After about half an hour's journey, Bai Xinzhou successfully arrived at Yanda School of Materials Science and Engineering.

And accompanied by Zhang Jin, he entered the superconducting materials laboratory.

As soon as he entered the laboratory, his eyes were attracted by a piece of gray fingernail-sized material floating not far away.

Mysterious and sci-fi, it makes people's eyes deeply drawn into it.

Xu Yuan, who came over at this time, was not surprised at Bai Xinzhou's performance. After all, that was a room-temperature superconducting material, which was enough to drive any country in the world crazy.

"Dean Bai."

"It is the latest research result of our laboratory, a superconducting material that can still have superconducting properties at room temperature."

"very nice."

Bai Xinzhou listened to Xu Yuan's words, uttered two words excitedly, then turned around to meet Xu Yuan's gaze and said, "The surprise you gave me this time really gave me a shock!"
