Chapter 419 Leave a Name in the History of Human Civilization!

But Yuan Shuai, who was very familiar with Ning Chen, knew that Ning Chen would not do such boring things. Ning Chen specially asked Yuan Shuai and others to participate in the experiment, so that everyone could enjoy the sense of accomplishment brought by the success of the experiment.

Moreover, the former commander guessed that Ning Chen should be sure that the experiment was successful by now, so he would let everyone go with confidence.

A few minutes later, the former commander brought the members of his experimental team to Ning Chen's experimental team, preparing to help Ning Chen and the others complete the experiment.

Seeing everyone's excitement, Commander Yuan knew that everyone must be looking forward to the final experimental results.

"The next experiment we need to do is to test the complete conductivity and superconducting properties of the product we just created. The expected superconducting critical temperature of this material may be relatively high, so please first prepare in advance……"

As everyone knows, the subject of Ning Chen's research this time is the preparation of a room temperature superconductor. Even if the product actually does not have such ideal properties, at least the superconducting critical temperature will definitely not be too low.

After listening to the experimental precautions explained by Ning Chen, everyone started to prepare to start the experiment.

In fact, the difficulty of this experiment itself is not that great. Many people are already very familiar with the measurement of complete conductivity of matter. Many people in the laboratory have already done hundreds or more experiments. , can complete the entire testing work very skillfully.

As for Ning Chen's original intention, he definitely didn't need so many people to do this experiment together. He just wanted more people to have the opportunity to participate.

With the completion of the preparation work, the entire superconducting circuit has been set up. Ning Chen led everyone to record the data on the measuring instruments.

Of course, the phenomenon that everyone expected for a substance to directly reach a superconducting state has not occurred. After all, the temperature in the laboratory has reached 26 degrees Celsius. If superconductivity can be achieved at such a temperature, it will indeed be possible. Somewhat beyond normal people's cognition.

"Okay, now we are ready to cool down. We must adjust the cooling speed to the slowest from the beginning, and we must focus on measuring changes in the resistance value of the material."

Cooling down at the slowest speed from the beginning is something that has never been seen in previous complete conductivity measurement experiments.

After all, in conventional complete conductivity measurement experiments, the superconducting critical temperature of materials is often very low, and many are even only slightly higher than absolute zero.

Under such a superconducting critical temperature range, it is obviously unnecessary to cool down very slowly from the beginning. This will cause the experiment to progress very slowly. Ning Chen usually adopts the method of cooling down first. Cool down quickly, wait until the ambient temperature is close to the expected superconducting critical temperature of the material, and then slow down the cooling rate.

The fact that Ning Chen was able to arrange this this time is enough to show that Ning Chen has very high confidence in the superconducting critical temperature of this material.

As the temperature in the measuring circuit decreases little by little, everyone is also paying close attention to the data in the measuring instrument.

I don’t know how much time passed, but the data on the instrument finally began to change significantly.

I saw that the resistance value displayed on the electrical measuring instrument suddenly fell off a cliff.

Even though this resistance value is far from zero resistance, such a change is enough to show that this material is about to enter the superconducting range.

"The current test environment temperature...hasn't dropped below 20 degrees Celsius? Oh my God, this substance is really terrifying!"

Everyone knows what such a superconducting critical temperature means. If this material can really be processed into strips used for superconducting circuits, then in many parts of the world, this material will not even need to be cooled at low temperatures. This directly realizes power transmission without resistance!

Of course, even if the superconducting critical temperature is as high as more than 20 degrees Celsius, some thermal insulation treatment will definitely be needed in some higher-temperature locations, but such insulation treatment will also have a very low cost, which is far lower than before. The so-called "high-temperature superconductors" have higher practicality.

Compared to everyone's shocked looks, Ning Chen was not shocked by this situation, and still had a confident expression on his face.

Since he dared to call everyone to the laboratory to witness such a historical moment, Ning Chen must have been prepared for it and was sure that this experiment would be successful.

The current experimental phenomenon is just an "appetizer". Next, is the moment to truly witness the miracle.

As the resistance of this substance began to drop rapidly, its resistance value soon approached the zero resistance range, and finally reached the zero resistance range prescribed by humans.

At this moment, the instrument also accurately recorded the exact temperature value when this substance reached the zero resistance state.

"290.08K! This is the first time we have measured the superconducting critical temperature of this material!"

This temperature value is unusually shocking, because no material has been able to reach such a high superconducting critical temperature before, even under ultra-high pressure.

But this experiment was conducted under standard atmospheric pressure, which means there will be no additional increase in the superconducting critical temperature of the material.

At this moment, people in the entire laboratory couldn't help but celebrate, feeling excited for this historic moment.

"This is a true room-temperature superconductor. With this material, we can directly realize zero-loss power transportation in many cases without imposing any additional conditions."

"Even if cooling is required, the cost is very low and can basically be ignored. Combined with our controllable nuclear fusion technology, we no longer need to worry about energy issues."

"I don't know what kind of shocking reaction the world will have after this result is publicly announced. This powerful technology that was once only in people's imagination has now really become a reality."

Compared to the excitement of others, Ning Chen wanted to appear relatively calm, because Ning Chen knew in his heart that according to the normal experimental process, the current experiment was far from over, and more detailed and complete measurements were needed.

"Don't rush to celebrate yet, we still have many sets of experiments to conduct."

Under Ning Chen's call, everyone calmed down again and continued to repeat the complete conductivity measurement experiment on this substance.

After several repeated tests, the superconducting critical temperature of this material was finally determined, and it was indeed 290.08K.

This proves that the data measurement of the experimental group is very accurate. Even if it is measured multiple times, the temperature error does not exceed one hundred K. This is an incredible accuracy in the industry.

After completing the measurement experiment of the complete conductivity of the material, Ning Chen and others successively conducted other measurement experiments on the superconducting properties of the material. To everyone's surprise, this material did meet the properties that all superconductors should have.

These experiments rigorously proved that Ning Chen and his laboratory team members discovered a true room temperature superconductor!

This time, Ning Chen was not in a hurry to publicly publish this result immediately, because even Ning Chen himself did not dare to say that he knew this new substance very well.

After briefly celebrating the results of the experiment with everyone, Ning Chen quickly returned to the laboratory and prepared for the next experiment with everyone.

Although the laboratory preparation of this material has been successful, and this material has been confirmed to be a room temperature superconductor in the strict sense, there is still a lot of work that needs to be done by Ning Chen and others.

First of all, the existing synthesis process of this substance is not easy. Not only does it require a lot of processes, but the cost is also very huge.

If you only synthesize a small amount of sample materials, this is not a difficult task, but if you synthesize them in batches to achieve the purpose of building large-scale superconducting circuits, this is something that is simply impossible to do now.

On the other hand, if you want to realize the application of superconducting power transmission, the preparation of wire strips of superconducting materials is also a task that must be broken through, because if superconducting wire strip materials cannot be synthesized, no matter how high the material is, The critical temperature of superconducting cannot be prepared into wires, which will greatly reduce the application value of the material.

In addition, the stability of this material, the density of wire strips and other properties are also related to its future application space. This is what Ning Chen and others need to deal with.

After Ning Chen told everyone about the follow-up work arrangements, everyone realized that this research topic was indeed far from over, which made everyone quickly readjust to their work status.

In order to better help the project team complete these tasks, Ning Chen decided not only to let members of his own experimental team carry out these tasks this time, but to find some experts from the Chinese Academy of Sciences.

Dozens of experts, including Yue Jiafeng, who is responsible for scientific research review work at the Chinese Academy of Sciences, and Academician Tao Wei, a famous superconducting material expert, were invited by Ning Chen to Shengzhou University. This situation has never been seen before.

Veteran experts like Academician Tao Wei have long passed the retirement age, but they still have not completely withdrawn from Xia Guo's scientific research community.

After learning about Ning Chen's invitation to him, Tao Wei was very excited and said that he would definitely come to Shengzhou University to help Ning Chen contribute a small part of his research.

It was rare for Yue Jiafeng to leave his job at the Chinese Academy of Sciences. After all, compared to other scientific research projects, Ning Chen's scientific research project was so important that he could temporarily leave his work to others.

Everyone came to Ning Chen’s materials science laboratory at Shengzhou University. After seeing Ning Chen, they all asked Ning Chen excitedly:

"Academician Ning, where is the room-temperature superconductor you discovered? Can we take a look now?"

"Have you really discovered a room-temperature superconductor with a superconducting critical temperature of 290K? Until now, I still can't believe this fact."

"Do we not have any energy problems now? In the future, the electricity bill will be cheaper than cabbage, and there may even be free electricity!"

The excitement of these experts is somewhat inconsistent with their current status, but regarding room temperature superconductivity, their emotions are indeed as exciting as ordinary people chatting about gossip.

Ning Chen was not offended by everyone's excessive reaction. As a scientific researcher, Ning Chen naturally understood their current excitement.

"Don't worry, I will answer these questions one by one with the experts. First of all, thank you very much for coming. You will definitely be of great help to our research. As you said, we have indeed discovered A strict room-temperature superconductor has not only completed its preparation, but also confirmed the measurement of all its superconductor-related properties. Of course, so far, we still have many problems that need to be solved..."

Listening to Ning Chen's explanation, everyone gradually realized some of the current problems related to 290K superconducting materials, and frowned and started thinking.

"Now it seems that these problems are indeed very difficult, and the workload required is also very huge. But don't worry, Academician Ning, we will definitely do our best to help you complete this work."

"Yes, Academician Ning, this is a major event that affects all mankind. Even if we pause other work at hand, there will definitely be someone who can help you solve these problems first."

"Room temperature superconductivity is a major technology that will be written in the history of human civilization. If we participate in the research of this project, we may be remembered in history. We don't think we are helping you, but we should Thank you Academician Ning for giving us the opportunity to participate.”

Seeing everyone's attitude, Ning Chen was very moved. He realized that he was not the only one fighting at the forefront of scientific research. There were many people who were as sincere about scientific research as he was.

This gave Ning Chen greater confidence in this scientific research project, and his sense of responsibility and belief became stronger.

"Okay! Then let us work together to overcome these difficulties one by one and leave our names in the history of human civilization together!"

…………

In the following days, under the leadership of Ning Chen, everyone continued the research on 290K room temperature superconducting materials.

After making a detailed plan and completing the assignment of tasks, Ning Chen was finally able to free up time to prepare a paper on 290K room temperature superconducting materials.

Naturally, Ning Chen will not spend too much energy on this matter. What Ning Chen only hopes is to let everyone know what work he and other team members have completed recently, and what are the latest developments in Blue Star's scientific research community. news.
