Chapter 433 Emphasis on scientific research and light application
Walking with Ning Jing in the corridor of the Superconducting Research Center, Qin Hai felt as if he was walking into a safari park alone. Behind every door, there was a bunch or several bunches of hateful eyes piercing him. If eyes could kill,
, Qin Hai was already riddled with holes at this time. Through the crack in the door, he seemed to be able to faintly hear a suppressed dialogue:
"Hey...who is this person? How come Jingjing is so familiar with him?"
"It's not just familiar, you didn't notice Jingjing's hand and she was still holding his!"
"It's so painful, how can I sleep tonight?"
"It's a good time that I can't sleep. My stove needs to be kept at a constant temperature for 16 hours. You can help me keep it..."
"..."
"Xiao Jing, you didn't do this on purpose, did you?" Qin Hai patted Jing Jing's hand holding his arm with a bitter face and asked her.
"What's intentional?" Jing Jing didn't react, she looked up at Qin Hai and asked.
Qin Hai whispered: "Why do I feel like there is murderous intent everywhere?"
"Huh?" Jing Jing turned his head and looked around in surprise. For a while, he only heard a series of bang bang bang bang sounds, and the doors of each experimental room were closed one after another. Jing Jing suddenly understood what Qin Hai was referring to, and couldn't help but giggle.
He laughed: "Are you talking about the senior brothers in our laboratory? That's right, I just did it for them to see. I told them to give up a long time ago, but they didn't listen."
"Oh, I accidentally became your shield." Qin Hai said, pretending to be regretful.
Jing Jing's pretty face was stunned, and she asked in a low voice: "Why, you still don't want to?"
Qin Hai could only express his position quickly: "Yes, yes."
"Well, that's pretty much it." Jing Jing nodded with satisfaction, then stretched the hand holding Qin Hai's arm forward, truly changing into a posture of holding Qin Hai's arm. If someone walked by them, they would notice that
.The faces of these two people turned red at this moment.
Fortunately, the corridor of the research center was not too long, and the two of them quickly reached the door of the laboratory where Chen Zongze was. Jing Jing let go of Qin Hai's hand, walked forward, and knocked on the door.
"Come in." A voice came from inside the room.
Jing Jing opened the door and led Qin Hai into the room.
"Ouch. Isn't this Mr. Qin? Why did you come without notifying me in advance?" Chen Zongze, who was wearing a white lab coat for experiments, saw Qin Hai coming in. He quickly stood up and greeted him with a smile.
.
Qin Hai also had a smile on his face. He shook hands with Chen Zongze and said, "I know Teacher Chen is very busy, so I didn't notify you in advance. I am here to visit you unexpectedly, so you won't disturb Teacher Chen, right?"
"How could it be? We have all been looking forward to your coming." Chen Zongze said enthusiastically. He explained a few words to the two assistants around him and asked them to continue completing the experiment at hand. Then he said: "Mr. Qin,
The smell in the laboratory is too strong, let’s go to my office to talk.”
Qin Hai agreed with a smile, and took Ning Jing with him to his office with Chen Zongze. After the guests and hosts sat down on the sofa respectively, Chen Zong pointed at Ning Jing and said, "Mr. Qin, last time Xiao Ning came from Anhe
I came back and brought some of your instructions. We studied it and found it very enlightening."
Qin Hai quickly waved his hand and said: "Teacher Chen is serious. That is not an instruction, it is just some random thoughts of mine. In addition, please don't call me Mr. Qin all the time. Xiaojing and I are the same generation, so just call me
Xiao Qin is fine."
"How inappropriate is this?" Chen Zongze said politely, then changed his words and said, "Okay, since Mr. Qin insists, I'll just call you Xiao Qin. This will make you look closer. Yes.
Okay, where did we just talk about..."
"Teacher Chen, you said that the ideas put forward by Qin Hai are very inspiring to us." Jing Jing reminded from the side.
"Yes, that's very inspiring." Chen Zongze said, "You suggested that we consider using light rare earth elements to replace yttrium elements based on yttrium barium copper oxide high-temperature superconducting materials. We have arranged students to conduct experiments separately. Preliminary
It shows that after using neodymium, samarium, europium, gadolinium and other elements to replace yttrium element, the copper oxide-based compound formed has stronger magnetic flux pinning force than yttrium barium copper oxide, and is expected to become a new group of new high-temperature ultrasonic materials with more development prospects.
guide material.”
Yttrium barium copper oxide high-temperature superconducting material is the first superconducting material in the liquid nitrogen temperature region independently developed in 1987 by the Chinese-American scientist Zhu Jingwu and the Chinese scientist Zhao Zhongxian. Its critical temperature has reached 90k. This material has
The birth of superconducting materials has greatly reduced the application cost of superconducting materials, and the commercial application of superconducting has emerged.
Before the emergence of yttrium barium copper oxide, all superconducting materials had to be at a temperature below 77K to have superconducting properties, so liquid helium with a boiling point of 4K was needed for cooling. Helium is a rare gas, and liquid helium is prepared
It generally needs to be extracted from some type of natural gas, so the cost is very expensive, which also limits the application of superconducting materials.
The emergence of yttrium barium copper oxide allows people to obtain the superconducting properties of materials at 77k, which is the boiling point of liquid nitrogen. The proportion of nitrogen in the atmosphere has reached 78%, making it an easy-to-obtain gas. The cost of liquid nitrogen
Less than 1/50 of liquid helium, the use of liquid nitrogen can significantly reduce the cost of superconducting materials, making the application of superconducting materials cheaper and more convenient.
In this era, the research on yttrium barium copper oxide superconducting materials is the hottest direction in the entire field of superconducting. The suggestions Qin Hai brought to Chen Zongze through Ning Jing were exactly the new developments in this field a few years later.
.In fact, even if Qin Hai didn't say anything, Chen Zongze might still try in this direction. What Qin Hai did was just give Chen Zongze a push.
According to the research and development of new materials introduced by Chen Zongze, Qin Hai added some opinions based on his own understanding, such as suggesting that Chen Zongze and the others pay attention to the relationship between the oxygen content in the material, the crystal structure of the material, and the lattice parameters, etc.
. He himself was not an expert in superconducting materials, and the opinions he put forward were only general remarks, but Chen Zongze could hear some forward-looking thoughts from them, so he quickly recorded them one by one and prepared to discuss them with his assistants in the future.
discuss in depth.
After talking about these academic issues, Qin Hai changed the subject and said, "Teacher Chen, in addition to visiting the research center, I am here at Peking University. There are other things I want to discuss with you."
"You tell me." Chen Zongze sat upright and said seriously.
Qin Haidao: "When we first established the research center, we discussed the operation model of the research center. The principle we set is to integrate industry, academia and research, to promote production through research, and to support research through production. I wonder if Mr. Chen still remembers it?
"
"Of course I remember." Chen Zongze said, "Xiao Qin, if you don't mention it, I plan to find time to ask you. The cost of our research center is huge. Those rare earth elements are more expensive than gold. We do experiments every day.
It's a waste of money. You don't feel bad, but we all do. I've always wanted to ask, what exactly do you plan to do when you talk about promoting labor through research? How can our research center turn into a female that can lay eggs?
chicken."
Qin Hai smiled and said: "This is what I want to talk about next. My idea is that on the one hand, the research on new superconducting materials cannot be stopped, and we must always be at the forefront of the world. On the other hand, like yttrium barium copper
Oxygen is a mature material, and we must complete process development as soon as possible to turn it into a final product."
"Process development..." Chen Zongze scratched his head and said depressedly, "We have actually been considering this issue, but we lack manpower. The research center now has more than 20 researchers and more than 50 PhDs.
The number of master's students is not small. But each person is in a pit, and no one can spare time to engage in craftsmanship. I am also very anxious."
"In the final analysis, we still don't pay enough attention to technology development, right?" Qin Hai said with a smile, "To put it bluntly, you can't produce high-level papers in technology, so everyone is not willing to do it. This is the most critical issue, right?
?”
"This..." Chen Zongze's face turned red. He had to admit that Qin Hai's words were indeed to the point.
Like all materials science research, the discovery of new materials and theoretical research are both work that can produce high-level papers. However, although the research on materials technology also has academic value, it is often difficult to get into the elegant hall. For Chen Zongze
For his assistants and students, high-level papers are a stepping stone for them to evaluate professional titles and find jobs. This is something that they absolutely cannot relax. Especially when superconducting theoretical research is in a state of blowout, who is willing to give up on academic research?
If you have the opportunity to become famous in the world, what kind of technological research will you turn to?
Qin Hai was a scientist in his previous life, and he is very aware of the phenomenon of "emphasis on scientific research and neglect of application" in academic circles. He also knows that the reason why China's materials industry lags behind Western countries is not because of the lack of ability of scientific researchers, but because of the lack of scientific research personnel.
It is because a large number of scientific research results cannot be transformed into actual products. In the previous life, faced with such a phenomenon, he could only sigh and be helpless. But in this life, he holds the research center's money bag in his hand and cannot tolerate this.
This phenomenon continues to exist.
"Teacher Chen, you just said that superconducting experiments are a waste of money. Even if I, Qin Hai, are a rich man, I cannot afford such consumption. If the research center cannot provide practical technology, then after the initial investment is used up,
, I’m afraid there will be no follow-up funds.” Qin Hai said to Chen Zongze in a threatening tone.
"Yes, yes, Xiao Qin, you are right." Chen Zongze lost his previous boldness and pointed out the country, and replied calmly. There is no way, Qin Hai is the financial backer of the research center, and Chen Zongze does not dare to do it casually
I really offended him. Besides, they had invested so much money in the early stage, and they promised to transform the research results into practical technology, but I couldn't do it, so I can't blame the other party for being aggressive.
"So, Xiao Qin, can you give us clear instructions on what you want us to do?" Chen Zongze asked Qin Hai. (To be continued, please search Piao Tian Literature, the novel is better and updated faster!
