"Tranquility, how is your paper doing?"

Outside the building door of the Superconductivity Research Center of Jingcheng University, Tranquility meets her classmate Yan Jiamin, who greets her with a smile.

"Soon, the real yàn has already been done, just wait for the results to be analyzed." Tranquility also said to Yan Jiamin with a smile.

Yan Jiamin said enviously: "You are really good, classmates in our class, you are probably the first to complete your graduation thesis, right?" And I estimate, no, I can be sure that your dissertation will definitely be able to win this year's excellent doctoral dissertation of the Ministry of Education, think about it, how many of them can we have in the country that have been published in Nature at the doctoral stage? ”

"I'm a blind cat and a dead mouse." Tranquility said modestly. She knew in her heart that she was able to make so many achievements in iron-based superconductivity, but it was definitely not as simple as a blind cat touching a dead mouse. The direction of iron-based superconductivity was chosen by Qin Hai for her, and Qin Hai's amazing foresight ability is beyond the reach of many "old cats" in the rivers and lakes.

It is not easy to do a PhD in superconductivity, because there are countless masters in the world doing this direction, and it is not easy for a doctoral student to make something different and able to withstand scrutiny. Yan Jiamin is doing theoretical research on copper-based superconducting materials, this field has been cultivated several times, and then to do it, can only do some work to fill in the gaps, it is not difficult to produce one or two SCI level papers, but to support a doctoral dissertation, there is something insufficient. Because of this, Yan Jiamin was in pain all day long, dreaming that he could suddenly discover a problem that no one had paid attention to before, and quickly make his doctoral dissertation.

Serenity, by contrast, is much more relaxed. She was the first researcher in the world to discover iron-based superconducting materials, and she has a lot of directions to do, each of which is capable of making very beautiful papers. Several choices. She decided to use the magnetic flux vortex state of iron-based superconducting materials as the topic of her doctoral dissertation. After a period of painstaking work and analysis, she has built a perfect model and is now just waiting for the text to be organized and ready to be officially submitted.

Among the Ph.D. students at the same level as Tranquility, several have shifted their research direction from copper-based superconductivity to iron-based superconductivity, and have quickly achieved very good results. Yan Jiamin belongs to the part that is still making copper-based materials. Over the past few years, the road has become narrower and narrower, and if it continues like this, it may be a problem for her to even graduate.

"Jiamin, it's really not good, you also turn around to make iron-based materials, right? Mr. Chen's research topics here are very large, and if you follow a random topic, you can make a doctoral dissertation in one or two years. "Tranquil and enthusiastic to build yì road.

A haze flashed across Yan Jiamin's face, and she shook her head and said, "I told my mentor about this idea. She resolutely disagreed with me to make iron-based materials, saying that copper-based materials are the right way, and the critical temperature of iron-based materials is still far lower than that of copper-based materials, which is impossible to have a future for development. ”

"This is not ......" Ning Ning almost wanted to say the word "nonsense", but finally remembered that Yan Jiamin's tutor Zhang Shengying was also her own teacher, and she couldn't accuse the teacher like this as a student, so she could only swallow the latter words back.

"The theoretical research of copper-based materials has now reached a dead end, and it is necessary to obtain copper-based superconducting materials with higher critical temperatures through guò theoretical research. There are almost no possibilities. The theory of iron-based materials is now very clear, and there is much to be done in terms of the microscopic mechanism of high-temperature superconductivity. How can Mr. Zhang confuse right and wrong like this? Tranquility said, in the end, she still used a relatively weak word to express her dissatisfaction with Zhang Shengying.

Copper-based materials are formed by doping copper oxide with other elements as the main body and forming a material with superconducting properties. This material is essentially a ceramic material, and the study of the conductive properties of ceramic materials has always been difficult, so the theoretical research of copper-based superconductivity has been in a state of divergent opinions for a long time. Tranquility said that this research has reached a dead end, and this is what it means.

If Yan Jiamin is not a doctoral student facing the pressure of graduation, then it is understandable to devote himself to the research of copper-based materials, after all, ten years of sharpening a sword. Maybe you can end up grinding something interesting. But there is a conflict between reality and ideals, Yan Jiamin does not have so much time to wait for a result that cannot be seen at present, Zhang Shengying does not let her do iron-based superconductivity, but leaves her on copper-based superconductivity, which is a little unkind.

Yan Jiamin himself is also a dumb eater of Coptis chinensis, and he can't tell if he suffers. She is already a 28-year-old young woman, and she already has a boyfriend she likes. The obstacle that now faces her and her boyfriend is that she has not yet graduated, regardless of the future workplace. Young people in this generation are very pragmatic, and if she can't graduate on time, then what will happen later is unpredictable.

"I really regret it now, I shouldn't have followed Boss Zhang." Yan Jiamin lowered his voice and said in a complaining tone. I don't know when the graduate students in colleges and universities have changed their words to call their supervisors bosses, not only behind their backs, but sometimes in front of their supervisors, they will also call themselves bosses, and the tutors generally laugh at this title.

"It's too late to change mentors now." Tranquility said, "Since your boss insists on letting you make copper-based materials, I'm afraid you can only do it." It's not that copper-based materials can't make anything, it's just that you may need to shift some of your mindset. ”

"I know my boss is getting a bit outdated...... Tranquility, you still say, it's not all your boyfriend's fault! When Yan Jiamin said this, he pretended to glare at Ningning, but there was a wry smile on his face.

Yan Jiamin's mentor Zhang Shengying was originally one of the authorities on superconductivity at Beijing University, but now he seems very lonely. The reason for this is that Zhang Shengying does not want to succumb to Qin Hai's requirements and is unwilling to devote some time and energy to the industrialization of superconducting materials, and therefore has a dispute with Qin Hai.

Qin Hai is the funder of the Superconductivity Research Center, and he will naturally not be polite to those who are unwilling to cooperate with him. Everyone knows that superconductivity is a direction that burns money, and without money, it is difficult to achieve success based on theoretical research alone. Compared with Chen Zongze, Du Xiangwang, Cao Guolin and others in the same teaching and research department, Zhang Shengying's actual funding gap is 108,000 miles, and in the past few years, his academic ability and academic status have dropped significantly.

Zhang Shengying is reluctant to Yan Jiamin to switch to the direction of iron-based materials, and he may not have the mentality of fighting with Qin Hai. Iron-based superconductivity is a direction pioneered by Tranquility, and it is also a direction that Qinhai focuses on supporting. Zhang Shengying can't get used to Qin Hai, hates Wujiwu, and hates tranquility and iron-based superconductivity together, so whenever she hears the words iron-based superconductivity, her nose is not a nose, her eyes are not eyes, and she is not angry.

Students may not know much about the academic achievements of their mentors, but they will never miss the gossip about their mentors. Yan Jiamin witnessed Zhang Shengying and Qin Hai bickering, so he naturally knew the reason. Thinking that she had followed such a mentor, how much benefit had not fallen, and she would have to delay her graduation and even all her future, she only felt so sad.

Tranquility also knew these things, as a person who stood firmly on Qin Hai's side, she didn't have a good impression of Zhang Shengying, and felt that it was reasonable for Qin Hai to wield a money stick against the other party. However, because of the sanctions against Zhang Shengying, Yan Jiamin was affected, and Tranquility felt a little uneasy.

"Jiamin, I have an idea, I don't know if it's suitable or not." Tranquility said.

Yan Jiamin said: "If you have any ideas, just say it, I don't mind." ”

In Yan Jiamin's opinion, what Ning Jing said was meaningless to her. Men are afraid of getting into the wrong business, women are afraid of marrying the wrong man, and what doctors are most afraid of is following the wrong mentor. Yan Jiamin has a bit of a complaining mentality now, but no matter how strong this resentment is, it can't change anything.

Ning Jing said: "Jiamin, you also know that I have gone abroad to attend several academic conferences, and my friend Qin Hai has also had some contacts with some authorities in the international materials community. If you don't mind, I can help you contact some scholars who are more authoritative in making steel-based materials in the world, such as Müller, Bernorz and others. If you go to them as an exchange student for a year, and do your doctoral dissertation there, I don't think Mr. Zhang can say anything, right? ”

"It's not so easy for exchange students to get in touch with each other." Yan Jiamin said suspiciously.

Ning Ning smiled: "Qin Hai still has some face, if he is allowed to say a word, there is a chance that he can do it." Jia Min, if you have such an idea, I will tell Qin Hai right away. ”

"Of course I have that idea." Yan Jiamin confirmed anxiously. The plan that Ning Jing said was actually something she had considered, but she couldn't find an opportunity to communicate. Hearing Tranquility say so sure now, her heart couldn't help but beat. A one-year overseas exchange student, and an exchange student to a world group master such as Müller and Bernorz, is a once-in-a-lifetime opportunity. With this opportunity, she will not only be able to produce an excellent doctoral dissertation, but will also benefit from her future development.

"Okay, I'll tell him." Tranquility nodded and said, she did this purely out of apology to Yan Jiamin, but it was inconvenient to say it at this level.

"Thank you, Tranquility, you are truly my best sister." Yan Jiamin put his arm around Ningning's neck and said exaggeratedly.

Without waiting for Ning Jing to say anything, Yan Jiamin's face suddenly changed as if he remembered something. Seeing that there was no one on the left and right, she brought her mouth to Tranquility's ear and said in an inaudible voice, "By the way, Tranquility, I forgot one thing. My boss...... It seems that I am going to make some articles about your graduation. (To be continued......)
