Chapter 433: Emphasis on scientific research but not on application

Walking in the hallway of the Superconducting Research Center with Tranquility, Qin Hai felt a kind of walking into the safari park alone. Behind each 'door', there were a bunch or bunch of hate eyes stabbing at him. If his gaze could kill people, Qin Hai would already be in trouble. He seemed to be able to hear a suppressed voice across the 'door' gap:
"Well ... who is this man, why is Tranquility so familiar with him?"
"It's more than familiar, you haven't watched Jingjing's hand holding him!"
"Special meow, painful, how can I fall asleep tonight!"
"I can't sleep well. I need to keep the stove at a constant temperature for 16 hours. You just help me keep it ..."
"..."
"Xiao Jing, aren't you doing this on purpose?" Qin Hai patted his hand holding his arm with a pained face, and asked her.
"What's intentional?" Tranquility didn't respond, and looked up at Qin Hai and asked.
Qin Hai whispered, "Why do I feel murderous everywhere."
"Huh?" Quietly, he turned his head and looked to the left and right, and for a while, he heard only a ‘chaotic’ sound, and the ‘doors’ of each experimental room were closed. Serenity suddenly understood what Qin Hai was referring to, and couldn't help giggling: "You mean these brothers in our laboratory? Yeah, I just showed them to them, and they let them die, they didn't listen. . "
"Well, take care not to be your shield." Qin Hai pretended to repent.
Quiet and cheeky, he whispered and asked, "Why, you don't want to?"
Qin Hai can only hurry and say: "I'm willing, willing."
"Well, that's pretty much the same." Quiet and nodded with satisfaction, he grasped Qin Hai's arm and stretched his hand forward, which really turned into a posture holding Qin Hai. If someone walks past them, they will find it. The faces of both men turned red at this moment.
Fortunately, the corridor of the research center was not too long, and the two of them quickly walked to the entrance of Chen Zongze's laboratory. Tranquil released Qin Hai's hand, walked forward, and knocked on the door of the room.
"Come in." A voice came from the room.
Tranquilly opened the 'door' and led Qin Hai into the room.
"Ah, this isn't President Qin? Why did you come without notice?" Chen Zong, wearing a lab coat for the experiment, saw Qin Hai coming in, and stood up quickly, laughing 'groan' Yin 'ground greeted.
Qin Hai also smiled. He shook hands with Chen Zong and said, "I know that Mr. Chen is very busy, so I didn't notify you in advance. Sudden visit, didn't bother Mr. Chen?"
"How is that? We have been looking forward to you," Chen Zong said enthusiastically. He confessed a few words to the two assistants around him and let them continue to complete the experiment at hand. Then he said, "General Qin, the lab smells too much, let's talk to my office."
Qin Hai agreed with a smile, and came with serenity to Chen Zong's office. After the guests and the host sat down on the sofas, Chen Zong pointed at Tranquility and said, "General Manager Qin, Xiao Ning returned from Anhe last time and brought you some instructions. We studied it and found it very enlightening."
Qin Hai quickly waved his hand and said, "Ms. Chen talked a lot. That was not an instruction, it was just some of my" thinking "thoughts. In addition, please don't call me a single Qin general, Xiaojing and I are ordinary , Just call me Xiao Qin. "
"How inappropriate is this?" Chen Zong said politely, and then changed his mouth. Said: "Okay, since President Qin insists, I'll call you Xiao Qin, so it seems closer. By the way, what did we just say ..."
"Mr. Chen. You said that the ideas proposed by Qin Hai were very enlightening to us." Tranquility reminded.
"Yes, it is very enlightening." Chen Zongze said, "You suggest that we consider using light rare earth elements instead of yttrium based on yttrium barium copper-oxygen high temperature superconducting materials. We have arranged students to conduct experiments separately. Preliminary It is shown that after replacing the yttrium element with neodymium, praseodymium, praseodymium, praseodymium and other elements, the copper-oxygen compound formed has stronger magnetic flux pinning force than yttrium-barium-copper-oxygen, which is expected to become a new type of high-temperature Guide material. "
Yttrium barium copper-oxygen high-temperature superconducting material is the first liquid-nitrogen temperature zone superconducting material independently developed by Chinese American scientist Zhu Jingwu and Chinese scientist Zhao Zhongxian in 1987. Its critical temperature reached 90k. The birth of this material has greatly reduced the application cost of superconducting materials, and the commercial application of superconductivity has dawned.
Before the appearance of yttrium barium copper oxide, all superconducting materials must have a temperature of 77k or less to have superconducting 'property' performance, so liquid helium with a boiling point of 4k needs to be used for cooling. Helium is a rare gas with a concentration of only 52,000ths in the atmosphere. The preparation of liquid helium generally requires extraction from some type of natural gas, so the cost is very expensive, which also limits the application of superconducting materials.
The appearance of yttrium barium copper oxide allows people to obtain the material's superconducting 'performance' at 77k, which is the boiling point of liquid nitrogen. Nitrogen in the atmosphere reaches 78% and is an easily accessible gas. The cost of liquid nitrogen is less than one-fifth of that of liquid helium. The use of liquid nitrogen can greatly reduce the cost of superconducting materials, making the application of superconducting materials cheaper and more convenient.
In this era, the research of yttrium-barium-copper-oxygen superconducting materials is the hottest direction in the entire superconducting field. The suggestions Qin Hai brought to Chen Zong through tranquility are just a few years later. . In fact, even if Qin Hai didn't say it, Chen Zong would probably try in this direction. What Qin Hai did was just to give Chen Zong a thrust.
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 should pay attention to the relationship between the oxygen content in the material and the crystal structure of the material, the lattice parameters, etc. . He is not a superconducting material expert himself, and his opinions are only general, but Chen Zong was able to hear some forward-looking 'sexual' thoughts, so he quickly recorded them one by one, ready to discuss this with his assistants in the future. Go deeper.
After talking about these academic questions, Qin Haihuan turned around and said, "Mr. Chen, this time I came to Beijing University, besides visiting the research center, there are other things that I want to discuss with you."
"You speak." Chen Zong was sitting critically and said earnestly.
Qin Haidao: "At the beginning of the establishment of the research center, we discussed the operation mode of the research center. The principle we set is the integration of production, teaching and research, promoting research with production, and supporting research with production. Do n’t you remember what Chen remembered? "
"Of course I remember." Chen Zongze said, "You do n’t mention it, Xiao Qin, I'm going to find time to ask you about it. The cost of the" flower "in our research center is incredible. Those rare earth elements are more expensive than gold. We do it every day. The experiments are all burning money, you do n’t feel bad, we all feel bad. I ’ve always wanted to ask, what you said is to promote research and production, what are you going to do, how can this research center become a Laying hens. "
Qin Hai laughed: "The next thing I want to talk about is this issue. My idea is that on the one hand, research on new superconducting materials cannot be suspended, we must always stay at the forefront of the world. On the other hand, like yttrium barium copper Oxygen is a mature material, and we need to complete the process development as soon as possible to make it the final product. "
"Technology development ..." Chen Zong scratched his head and said, depressed, "We have been thinking about this problem, but we lack manpower. The research center now has more than 20 researchers, and more than 50 doctors, The number of master's degree students is not small. But there is a pit one by one, and no one can afford to do craftsmanship, and I'm too anxious. "
"In the final analysis, do we not pay enough attention to process development?" Qin Hai said with a grin. "To put it bluntly, craftsmanship cannot produce high-level papers, so everyone is not willing to do it. This is the most critical issue. ? "
"This ..." Chen Zongze's face was a little red, and he had to admit that Qin Hai's remarks were indeed sharp and he had an idea.
As with all materials science research, the discovery and rationale of new materials are jobs that can produce high-level dissertations, and the research on materials technology, although also of academic value, is often difficult to enter the hall of elegance. For Chen Zongze and his assistants and students, high-level dissertation is their job title and the ‘door 'for finding a job. This is absolutely something we ca n’t relax. Especially when the superconducting theory is in a state of blowout, who is willing to give up the opportunity to become famous in academia and go to what kind of craft research?
Qin Hai was a scientist in his previous life, and he was very clear about the phenomenon of "emphasizing scientific research and neglecting applications" in the academic circle. He also knows that ~ EbookFREE.me ~ China's material industry is lagging behind Western countries. It is not because of insufficient scientific research personnel's ability, but because a large number of scientific research results cannot be converted into actual products. In the previous life, in the face of such a phenomenon, he could only be amazed and powerless. In this life, he was carrying the research center's money bag in his hand, but this phenomenon could not be tolerated.
"Mr. Chen, you said just now that the superconducting experiment is burning money. Even if Qin Hai is a local tyrant, I can't afford such consumption. If the research center cannot provide practical technology, then after the initial investment has been completed, I am afraid there will be no follow-up funding. "Qin Hai said to Chen Zong in a threatening 'kiss'.
"Yes, yes, Xiao Qin, you are right." Chen Zong replied without the boldness and kindness that had pointed the rivers and mountains before. No way, Qin Hai is the gold master of the research center, but Chen Zong dare not offend him casually. Besides, people have already invested so much money in the early stage, and they said that if they want to turn the research results into practical technology, they ca n’t blame the other party if they fail to do so.
"So, Xiao Qin, can you tell us clearly what we want to do?" Chen Zong asked Qin Hai.
ps: Checking the information is going to be crazy, maybe there is something wrong, please forgive me. Superconductivity is too complicated. . --615aahhh + 24348493->
