Chapter 345 Did you already know this?
It was in this unrestrained state that Ning Chen finally designed the ideal new superconducting material.
“If I have to classify this material as a superconducting system... I will temporarily call it a 'metal alloy composite superconductor'. Of course, I don't like to forcefully classify materials now. The classification is just for the convenience of distinction, so I have to divide it first..."
At this moment, other people in the laboratory have different ideas in their hearts.
Although Xu Zhou could not fully understand Ning Chen's thinking, he only felt that Ning Chen was really a genius for being able to design such incredible superconducting materials.
The former commander was thinking hard about Ning Chen's thoughts in order to try his best to understand Ning Chen's thoughts.
Pierce has understood a lot of Ning Chen’s thoughts and understood why Ning Chen designed such a substance.
"Teacher Ning, do you hope to use this new type of superconducting material in the aerospace field?"
Ning Chen was a little surprised when he heard Pierce's words, because this is exactly what he said true thoughts.
In fact, Pierce originally wanted to say directly that this would be a superconducting material used in rockets, but to be conservative, Pierce did not say it in such detail all at once.
Ning Chen did not immediately answer Pierce's guess, but asked:
"Kim, why do you think so?"
"It's actually very simple, because Teacher Ning, you are designing When it comes to this kind of superconducting material, great emphasis is placed on the comprehensive properties of the material. If it is only used to transmit electric current, other properties are actually relatively minor except for complete conductivity and superconducting critical temperature.”
Pierce's answer has a very sufficient theoretical basis. This does not mean that the strength and lightness of matter are unimportant, but in comparison, these properties will appear relatively minor.
But in Ning Chen’s design, these properties were considered almost equally, which allowed Pierce to come to this conclusion.
"Yes, I do hope that this material can be used in the aerospace field, and in rocket systems. Of course, we must keep this matter strictly confidential. Well, here is the confidentiality agreement, we will do it now Let’s sign it first.”
Ning Chen took out the prepared confidentiality agreement and distributed it to everyone in the laboratory. After everyone read the confidentiality agreement, they all completed the signing process one by one.
In fact, Ning Chen still trusts his lab partners very much, but Ning Chen will not cancel such a process because of trust. After all, this matter is very important, and such a sense of ritual is still necessary. some.
After collecting everyone’s confidentiality agreement, Ning Chen directly explained the next work without any hesitation.
"Okay, now this project has officially started. Let's study the synthesis method of this material now, and strive to achieve a technological breakthrough as soon as possible..."
In the following time, everyone discussed the possible synthesis methods of this material based on its various characteristics.
We proposed methods including electrophoretic deposition, in-situ chemical reduction, layer-by-layer deposition, direct dispersion, and in-situ polymerization. Ning Chen also recognized these methods.
“These methods all have their own advantages. The electrophoretic deposition method has better preparation effects. The in-situ chemical reduction method is very suitable for processing composite materials containing graphene and carbon nanotubes. The layer-by-layer deposition method is suitable for forming structurally complete materials. , materials with stable performance, the direct dispersion method is suitable for synthesizing polymer composite materials. Of course, we need to use these methods more flexibly in actual work, and do not stick to any one method. ”
< br>Ning Chen and others are heading towards a brand new path. Naturally, they cannot mechanically apply the original method, but need to develop a new method of their own.
……
In this way, Ning Chen, together with others in the laboratory, began research on the synthesis of this new type of superconducting material.
This is the first time for Ning Chen and others to study such a complex superconducting material, and the difficulties they face are unprecedented.
Fortunately, Ning Chen has enough trustworthy partners, so that Ning Chen does not have to do everything by himself and can focus on the main core work.
In addition to the powerful scientific research ability itself, Ning Chen can also use Xiaozhi's information notification ability and the ability gains he obtains after using evolution points to help him analyze experimental phenomena faster.
During the contact during the experiment, Pierce gradually noticed the changes in Ning Chen.
"It's strange... Teacher Ning seems to be much more powerful than before. This change is really incredible."
Although Pierce had admired and admired Ning Chen's ability before, Pierce It can still be clearly felt that Ning Chen's ability in materials science has been significantly improved.
Such a speed of progress is definitely not something ordinary humans can easily achieve.
However, Pierce did not attribute this to something incomprehensible. He only felt that it was due to Ning Chen's talent and hard work.
The first stage of experiments is over. Although Ning Chen and others have not yet successfully prepared the ideal new superconducting material, Ning Chen is quite satisfied with some of the results achieved in this stage.
Ning Chen called everyone together to summarize the experimental results at this stage.
“In these days of experiments, we have solved many problems that have not been solved before and filled many gaps in human research on superconductors. We have completed almost half of the work to successfully synthesize this material. ..."
Ning Chen's words were not exaggerated. In Ning Chen's own opinion, they were indeed very close to the success of the experiment.
In real scientific research, whether it is one percent or ninety-nine percent of the experimental progress, it is a relatively vague concept.
Sometimes, it seems that the experiment is almost complete, but in fact, if you continue in this direction, it is actually a dead end.
But sometimes, it seems that the experiment does not have any clues, but if you break an inch further, the most difficult problem can be easily solved.
Ning Chen feels that this experiment is moving in the right direction, and as long as given time, the ideal product will be obtained.
In this way, Ning Chen and others started a new stage of experiment.
Time passes day by day, no matter whether the daily experiment is a success or a failure, Ning Chen maintains a very peaceful attitude and constantly adjusts the future experimental plan.
Finally, after several months of experiments, Ning Chen and others successfully produced the ideal product.
Ning Chen immediately tested the structure of the product and confirmed that the substance was exactly the same as the one he designed. After getting such a result, Ning Chen couldn't suppress his emotions for a while. His heartbeat suddenly became faster and his face became a little rosy.
Because at this moment, Ning Chen was finally convinced that the substance he designed out of thin air actually existed and could be synthesized through experiments.
This further proves the feasibility of Ning Chen in material design. He can confirm the possible properties of the material before synthesizing it, and speculate on the possible synthesis method of the material through the structure of the material.
At this moment, others don’t know what this product is like, and are just waiting for Ning Chen to lead everyone to test the properties of the product.
But at this time, everyone heard Ning Chen say:
"The next testing work will be carried out by you."
Hearing Ning Chen's words, everyone felt a little surprised. But he had no choice but to hear Ning Chen's arrangement.
Everyone felt that perhaps due to long hours of high-intensity work, Ning Chen's body could not bear the fatigue, so he handed over such an important experiment to others.
But in fact, Ning Chen had been tense for too long just because of this experiment. Once he relaxed, it would be difficult to return to his previous state immediately.
Ning Chen had to calm down his emotions before proceeding with the follow-up work.
Fortunately, based on Ning Chen's analysis just now, he has confirmed that this material is the material in his mind, and others are fully capable of completing the rest of the work smoothly.
As the test experiment progressed, everyone immediately came to preliminary experimental conclusions.
"Teacher Ning! The microstructure of this material is exactly the same as what we originally designed! We actually created this substance!"
"Yeah, I thought There will be some deviations this time, but I didn’t expect there to be any difference at all. The accuracy of this synthesis is really incredible.”
Compared to the excitement of others, Ning Chen seemed much calmer and did not have much emotional fluctuations because of these new conclusions.
Ning Chen must work hard to calm down. After all, this project is far from over. Only by maintaining a good attitude can he devote himself to the work in the final state.
At this time, Xu Zhou came to Ning Chen and whispered:
"Teacher Ning, looking at your appearance just now, it seems that you are not surprised by the results of this experiment. Could it be that you have seen it a long time ago? "Excuse me, is this the material you want?"
Xu Zhou has always been very good at observing Ning Chen's micro-expressions. Seeing Xu Zhou say this, Ning Chen smiled and said:
"Actually, I was also very excited, but I got excited earlier than you. When the experiment was just finished, I was already excited."
"Teacher Ning...you mean , when the experimental product was just made, you knew that this was our ideal product?”
“Yes, so at that moment, I couldn’t suppress my inner emotions, and I couldn’t even control it. The subsequent experiments cannot be completed well."
"But... Teacher Ning, are you really so good now that you can see the microscopic properties of matter without even using a scanning electron microscope?"
"Well...that's not to say, it's more of an intuition from scientific research. After seeing the product this time, I was very confident that this must be my ideal product. The superconductor in ”
Naturally, Ning Chen would not tell Xu Zhou everything, but after listening to Ning Chen's explanation, Xu Zhou did not have too many doubts. After all, Ning Chen would always do something incomprehensible.
When the measurement experiment was carried out for a period of time, Ning Chen felt that he could completely control his emotions, so he said to others:
"Okay, I should also participate. Some experiments. Leave it to me to measure the superconducting critical temperature of this material."
Ning Chen took out some experimental samples and came to the superconducting laboratory to prepare for measurements. The superconducting critical temperature of this substance.
This is one of the experiments that Ning Chen is most familiar with. However, when conducting this experiment, Ning Chen still maintained a cautious attitude and did not dare to make any oversights.
Ning Chen predicted that the superconducting critical temperature of this material is around 210K to 230K. If the final experimental conclusion confirms Ning Chen’s prediction, this will be one of the superconductors with the highest superconducting critical temperature known in the world. .
Of course, those substances that exhibit superconducting properties under ultra-high pressure conditions are not included in this discussion.
Because the predicted superconducting critical temperature of this material is very high, Ning Chen carefully paid attention to measuring the temperature changes in the circuit and the resistance value in the line after cooling down briefly.
At the same time, Ning Chen is also using Xiaozhi's information sensing function to understand more detailed internal data.
I don’t know how long it took, but Ning Chen’s eyes suddenly changed.
Because judging from the data transmitted from Xiaozhi, the microscopic particles of this substance have changed.
Soon, the line resistance data measured by the instrument began to drop sharply.
“At a temperature of 240K, it has already begun to enter the superconducting temperature range... It seems that it will not be long before this material can achieve complete conductivity.”
When this material enters the superconducting temperature region, the decreasing trend of resistance approaches linearity, which is rare among other superconductors.
When the temperature of the test circuit dropped to about 220K, Ning Chen finally saw the complete conductivity he had dreamed of.
"220K... is probably the superconductor with the highest superconducting critical temperature under normal pressure that is known now..."
The measurement results were just within Ning Chen's prediction range, which made Ning Chen a little surprised. I felt a lot more relieved.
When the other members of the laboratory learned the news, they were too excited to carry out the experiments at hand, and came to Ning Chen to discuss excitedly.
"Teacher Ning! It turns out to be a 220K superconductor! The application space of this superconductor will be very wide, and it is also very suitable as a wire for transmitting current."
"Yes, even if The other properties of this material are not outstanding, but this is a new achievement that is enough to shock the world. I am afraid that the popularization of superconducting power transmission will not be too far away. ”
Ning Chen could understand the excitement of others. After all, after so many days of experiments, he finally got the results that everyone expected.
