Chapter 137 New iron-based superconductivity record!
“Have you entered the superconducting transition temperature zone?”
In fact, as long as the material Ning Chen synthesized this time is still a superconductor, the entire experiment will be successful in general. .
As for the true superconducting critical temperature of matter, it is definitely not easy to accurately predict because there are so many influencing factors.
But after Ning Chen carefully looked at the data on the screen, Ning Chen discovered a new key point.
"No...it is not just entering the superconducting transition temperature, but...directly becoming a superconductor!"
Judging from the data obtained from the resistance measuring instrument, the resistance of this substance at this time is, It has dropped to 10^(-25)Ω.
Soon, Ning Chen figured out the reason.
“Not all superconductors will enter the superconducting transition temperature zone before reaching the superconducting critical temperature. For example, this kind of material can directly reach the superconducting state almost instantly . ”
If classified from the transition temperature range, superconductors can be divided into those with a wide transition temperature range and those with a very narrow transition temperature range.
For the former, there will be nodes with multiple temperatures including superconducting initial transition temperature, intermediate transition temperature, and zero resistance temperature.
But for the latter, there will only be one superconducting critical temperature.
After thinking clearly about the reasons, Ning Chen immediately refocused his energy on his experiment.
Although the superconducting critical temperature of this material has just been measured, Ning Chen still needs to conduct more experiments to avoid experimental accidents.
Finally, after some detailed measurements, Ning Chen came to the final conclusion.
The superconducting critical temperature of this material is indeed around 55K, and it also meets the properties required by various other superconductors.
At this moment, Ning Chen was certain that he had discovered a brand new iron-based superconductor and set a superconducting critical temperature record for iron-based superconductors!
Ning Chen couldn't help but feel excited, but it was not as exciting as he imagined.
Perhaps because Ning Chen has made too many valuable achievements before, Ning Chen can accept success and failure relatively calmly.
As Fan Zhongyan said in "Yueyang Tower", don't be happy with things and don't be sad with yourself.
Whether facing success or failure, you can maintain a calm and constant attitude.
Being too obsessed with success or being too afraid of failure will have a considerable impact on scientific research work.
Of course, Ning Chen was always happy after the experiment was successful.
Ning Chen returned to the laboratory. Xu Zhou saw Ning Chen’s expression and knew that Ning Chen’s experiment was probably successful.
"How about, what is the critical temperature of superconducting this time?"
"55K." Ning Chen said calmly.
“55K? This should set a new superconducting critical temperature record for iron-based superconductors, right?”
“Well, according to the information that can be found so far, it is indeed true. Of course, is there? If it is not published publicly, it cannot be determined.”
“Hey, this kind of thing is not considered a confidential scientific research project, it is just at the level of academic research. No matter who discovers it first, it must be. You will rush to publish a paper. Of course, if you really discover a high-temperature superconductor with special application value, you cannot easily publish it publicly."
Ning Chen naturally knows this. At this stage, Ning Chen. Chen Chen doesn't care too much about publishing papers or anything like that.
Based on Ning Chen's current achievements, there is no problem in graduating with a doctorate or even staying in school, but there are still some other processes that need to be met.
Continuing to stay in the laboratory to conduct research is more of Ning Chen's heartfelt behavior, and he will not deliberately pursue the fame and fortune that these studies will bring to him.
Of course, since this topic has produced results and meets the conditions for public publication, the paper will definitely be compiled into a paper and continue to be submitted to appropriate academic journals.
……
Ning Chen spent several days to complete the writing and proofreading of this paper, and submitted the paper to Nature magazine again.
This time, Ning Chen didn't even show Xu Zhou the paper. He just told Xu Zhou that he was submitting the paper to "Nature" again.
Xu Zhou was already used to these things. It seemed quite appropriate that Ning Chen was called an "essay madman" by the media.
After completing the submission of this paper, Ning Chen continued to devote his time to Piati's horizontal subject.
This project has entered an advanced stage and is expected to be completed soon.
Ning Chen also hopes to complete this project quickly so that he and Xu Zhou can have time to start new topics earlier.
Although horizontal projects are easier to make money, their role in evaluating professional titles is far less important than vertical projects. A balance should be found between the two. In the morning, Ning Chen saw the message Zhou Li sent to him.
Zhou Li: "Teacher Ning, I'm sorry to bother you. I would like to ask if you know any better tutors. Yangyang is now in his third year of high school. I want to improve his math scores. Rush upward."
After Ning Chen saw the news, he felt a little sorry for Zhou Li and Xu Yang.
Ning Chen also told Zhou Li before that as long as he had time, he was very willing to take Xu Yang to the college entrance examination.
But as Ning Chen had more and more things to do, it was indeed difficult for Ning Chen to find time to be a tutor.
And now that Ning Chen already has a lot of wealth, he will no longer value the little money he can earn from being a tutor.
After thinking about it, Ning Chen replied:
"Sister Zhou, I have a few classmates who are also tutors. Let me ask them. What are your requirements for tutors? , how to calculate the class fee? "
"Teacher Ning, you must know your classmates better than me, just help me find them. The fee is still the same as before, three hundred yuan for one and a half hours."
"Okay, Sister Zhou, let me ask and then get back to you."
The first thing Ning Chen thought of was his roommates Yang Yan and Yuan Shuai.
The two of them have also been working part-time as tutors, and they can teach mathematics, physics and chemistry. With their abilities, teaching Xu Yang should not be a big problem.
If we look at teaching ability alone, Ning Chen thinks that Yang Yan may be slightly stronger.
Yang Yan has always been ranked second in the materials major in each semester, second only to Ning Chen, and this is achieved even when he does not study so seriously.
In addition, because of participating in the student union, Yang Yan will have stronger expressive skills, which is also an advantage in teaching.
However, Ning Chen still hopes to let Yuan Shuai give it a try first, because Yuan Shuai's family conditions are not good and he needs some part-time income more than Yang Yan.
According to Ning Chen’s understanding, there are five brothers and sisters in Yuan Shuai’s family, and Yuan Shuai’s father cannot do heavy work due to physical reasons, so the family’s annual income is very limited.
Even Yuan Shuai’s college tuition and living expenses depended on the school’s grants and student loans.
Thinking of this, Ning Chen sent a message to Yuan Shuai on QQ.
"Commander Yuan, do you have time at noon? Please go out for a meal. Don't tell others about this yet."
After a while, Ning Chen received a reply from Commander Yuan.
"If you have time, Ning Chen, why don't I treat you? You have treated me too many times before."
"No, no, I still owe you several meals before. Well, let’s meet at the south gate at noon.”
After finishing the morning experiment, Ning Chen came out of the laboratory and came to the south gate of Shengzhou University.
The former commander had already arrived at the south gate in advance. When he saw Ning Chen, he smiled and said:
“Ning Chen, it’s been a long time no see.”
“Yes, we have indeed not seen each other for a while. Handsome, what do you want to eat?”
“I can do it, it’s up to you.”
“How about going to eat grilled fish?”
"No problem."
The grilled fish restaurant is very close to the south gate, so you can go back earlier.
At the grilled fish restaurant, Ning Chen ordered a grilled fish set meal for two people. While waiting for the food to be served, the two chatted about their current situation.
"Commander Yuan, are you busy every day now?"
"Yes, you are still quite busy. In addition to studying, you also have to find time to participate in Daiso's experiments."
< br>
"Commander Yuan, have you signed up for Daiso?"
The so-called Daiso, also known as the "College Student Innovation and Entrepreneurship Training Program", allows undergraduates to participate in some experimental projects in advance, especially for those who want to study There are still great benefits for graduate students.
"Yes, didn't you suggest that we should enter the laboratory as soon as possible, so Yang Yan and I signed up together. Now that we are in the same experimental group, the progress of the project is relatively smooth."< br>
Learning that Marshal Yuan and Yang Yan had entered the laboratory in advance, Ning Chen was also very happy for them.
