Material Empire

"Quiet, how is your dissertation doing?"

Outside the gate of the Superconducting Research Center of Jingcheng University, Tranquility met her classmate Yan Jiamin, who greeted her with a smile. ()

"Quickly, the experiments are all done, just wait to analyze the results." Tranquil also said to Yan Jiamin with a smile.

Yan Jiamin said with envy: "You are really good, our classmates, are you the first to complete your graduation thesis? And I guess, no, I can be sure, your thesis will definitely be able to get this year's Ministry of Education. Excellent doctoral dissertation, think about it. Nature was published at the doctoral level. How many of us can we have in the country? "

"My blind cat has run into a dead mouse," said quietly and modestly. She knew in her heart that she could make so many achievements in iron-based superconductivity, but it was definitely not as simple as a blind cat touching a mouse. This direction of iron-based superconductivity was chosen by Qin Hai for her. Qin Hai's amazing ability to foresee is beyond the reach of many old cats.

Superconducting doctors are not easy to do, because there are countless masters in the world in this direction. It is not easy for a doctoral student to make something different and able to withstand scrutiny. What Yan Jiamin is doing is the theoretical research of copper-based superconducting materials. This field has been cultivated several times, and further work can only be done to fill in the gaps. It is not necessary to produce a paper or two. Difficult, but to support a doctoral dissertation, it is not enough. Because of this, Yan Jiamin was suffering all day long, dreaming that he could suddenly find a problem that his predecessors hadn't paid attention to, and quickly completed his doctoral dissertation.

In contrast, tranquility is much easier. She is the first researcher in the world to discover iron-based superconducting materials. She has a lot of directions in her hands, and can make very beautiful papers in each direction. After several selections, she determined to use the magnetic flux vortex states of iron-based superconducting materials as her doctoral thesis topic. After a period of arduous experimentation and analysis, she has set up a perfect model, and now she can only formally submit it after waiting for the text to be organized.

Among PhD students at the same level as Serenity. Several people have switched their research direction from copper-based superconductors to iron-based superconductors, and have achieved very good results quickly. Yan Jiamin belongs to the part that is still making copper-based materials. Over the years, the road has narrowed. Going on like this, she might even have problems graduating. Fiction/

"Jiamin, it's really impossible. You can also turn to iron-based materials? Teacher Chen has a lot of research topics. You can just follow a topic. You can finish your doctoral thesis in one or two years." Quietly enthusiastically Suggested.

A haze flashed on Yan Jiamin's face, she shook her head and said, "I told my mentor about this idea, and she resolutely disagreed with me as the iron-based material, saying that copper-based materials are the right way. Iron-based materials so far The critical temperature is still much lower than copper-based materials, which is unlikely to be promising. "

"This isn't ..." Tranquil almost wanted to say the word "nonsense." Finally, she thought that Yan Jiamin's mentor Zhang Shengying was also her own teacher. As a student, she couldn't blame the teacher, so she had to swallow the following words.

"Theoretical research of copper-based materials has now entered a dead end. If you want to obtain copper-based superconducting materials with higher critical temperatures through theoretical research. There is almost no possibility. The theory of iron-based materials is now very clear, and at high temperatures There are many things to do in the superconducting micro-mechanism. How can Teacher Zhang confuse right and wrong like this? "Said Tranquility. At the end, she used a weaker word to express her dissatisfaction with Zhang Shengying.

The copper-based material is a material with superconducting characteristics, which is formed mainly by copper oxide and doped with other elements. This material is a ceramic material in nature, and the research on the conductive properties of ceramic materials has always been difficult. Therefore, the theoretical research of copper-based superconductors has been in a state of divergence for a long time. Tranquility research has entered a dead end. That's what I mean.

If Yan Jiamin is not a doctoral student facing the pressure of graduation. So devoted to the research of copper-based materials, there is nothing wrong with it. After all, sharpening a sword in ten years, eventually it may be able to grind something interesting. But reality and ideal are in conflict. Yan Jiamin didn't have so much time to wait for a result that has not been seen yet. Zhang Shengying did not let her do iron-based superconductivity, but left her on copper-based superconductor, which was a little unfriendly.

Yan Jiamin himself was dumb to eat Coptis chinensis, and couldn't say it. She is already a 28-year-old young woman, and she also has a favorite boyfriend. Obstacles now facing her and her boyfriend. That is, she has not graduated, regardless of her future work unit. The young people of this era are very pragmatic. If she can't graduate as scheduled, the future will be unpredictable.

"I really regret it now, and I shouldn't follow Boss Zhang." Yan Jiamin lowered his voice and said in a complaining tone. I do n’t know since when graduate students in universities have unified their mentors as bosses. Not only do they say it behind the scenes, sometimes they also call the boss in front of the mentor, and the mentor generally smiles at this title. of.

"Now it's too late to change mentors." Tranquil said, "Since your boss insists that you make copper-based materials, I'm afraid you can only do it. Copper-based materials are not absolutely impossible, but you may need to transfer Some ways of thinking. "

"I know, what my boss is doing is a bit out of date ... Serenity, what else do you say, it's not all your boyfriend's harm!" Yan Jiamin said here, glaring at Serenity deliberately, but with a faint face With a trace of bitter smile.

Yan Jiamin's mentor Zhang Shengying was originally one of the superconducting authorities of Jingcheng University, but now it seems very lonely. The reason for this is that Zhang Shengying did not want to submit to Qin Hai's requirements, was unwilling to devote some time and energy to the industrialization research of superconducting materials, and therefore had a dispute with Qin Hai.

Qin Hai is the funder of the Superconducting Research Center. Naturally, people who are unwilling to cooperate with themselves will not be polite. As soon as a notice is published, Zhang Shengying is entered into a separate volume. In terms of experimental conditions, funding, etc. control. Everyone knows that superconductivity is a direction of burning money. Without money, it is difficult to achieve success based on theoretical research alone. Compared with Chen Zongze, Du Xiangwang, Cao Guolin, etc. of the same teaching and research department, Zhang Shengying's experimental funding was 108,000 miles away. Over the next few years, his academic ability and academic status have dropped significantly.

Zhang Shengying did not want Yan Jiamin to turn to the direction of iron-based materials, so he may not have the mentality of fighting with Qin Hai. Iron-based superconductivity is a direction of serene creation, and it is also a direction supported by Qin Hai. Zhang Shengying couldn't get used to Qin Hai, hated Wu Wuwu, and even hated tranquility and iron-based superconductivity. So when I heard the words of iron-based superconductor, the nose was not nose, and the eyes were not eyes. Don't call one place.

Students do not necessarily know much about the academic achievements of their mentors, but they will definitely not miss the gossip about their mentors. Yan Jiamin witnessed Zhang Shengying and Qin Hai quarreling, and naturally knew why. Thinking of following such a mentor, the benefits did not fall away, and she would delay her graduation and all her future. She only felt sad.

Tranquil also knows these things. As a person who stands firmly on the side of Qin Hai, she doesn't have a good opinion of Zhang Shengying, and feels that it is reasonable and reasonable for Qin Hai to use a big stick of money to deal with the other party. However, because of the sanctions against Zhang Shengying, which caused Yan Jiamin to suffer, Tranquility was a little uneasy.

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

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

In Yan Jiamin's opinion, what quiet thought said was meaningless to her. Men are afraid of entering the wrong line and women are afraid of marrying the wrong man. The doctor is most afraid of following the wrong mentor. Yan Jiamin now has a resentment mentality, but this kind of resentment can't change much.

Tranquility said, "Jia Min, you know, I have gone to several academic conferences abroad, and my friend Qin Hai and some authorities in the international materials community have some contacts. If you don't mind, I can contact you Some scholars who are more authoritative in the field of steel-based materials, such as Mueller, Bernards, etc. You go to them as exchange students for a year, and do a doctoral dissertation there. I do n’t think Teacher Zhang has What does Fa say? "

"How could exchange students be so easy to contact," Yan Jiamin said doubtfully.

Tranquil laughed: "Qin Hai still has some face ~ www.novelmtl.com ~ If you let him say a word, chances are good. Jiamin, if you have such an idea, I will talk to Qin immediately Hai said. "

"Of course I have this idea." Yan Jiamin anxiously confirmed. Tranquility's plan was actually what she considered, but she couldn't find a chance to communicate. Now listening to Serenity being so sure, her heart could not help slamming and jumping. One year of overseas exchange students, and to exchange masters with world group masters such as Mueller, Bernoz, this is a once-in-a-lifetime opportunity. With this opportunity, she can not only make an excellent doctoral dissertation, but also benefit countless developments in the future.

"All right, let me talk to him." Serenity nodded and said that she was doing this purely because of her apologies to Yan Jiamin, but this layer is inconvenient to say.

"Thank you, Tranquility, you are really my best sister." Yan Jiamin said with a hand around his neck and exaggerated.

Without waiting for Quiet to say anything, Yan Jiamin suddenly seemed to remember something, his face suddenly changed. When she saw that there was no one left or right, she put her mouth to the quiet ears and said in an obscure voice: "Yes, quiet, I forgot one thing. My boss ... seems to be going to take you for graduation Do something. "(To be continued.)
