Material Empire

After Qin Hai explained his thoughts to Nie Sen, he left, leaving Nie Sen alone in the room, sometimes frowning and sometimes ecstatic, and couldn't sleep well all night.

It is easy to come up with the concept of graphene, but there is still a lot of arduous work to be done to prepare graphene samples that exist stably, and it will take several years of hard work. Qin Hai himself is not an expert in graphene research. He cannot explain all the technical details to Nie Sen. He can only point out one direction, and then give Nie Sen enough authorization to fully mobilize manpower and material resources to complete this task. A cross-century scientific research work.

Nie Sen naturally understands the difficulty of scientific research. In his mind, he feels that if he can complete the task assigned by Qin Hai in 10 years, it will be considered a consummation of merit. Such a scientific research achievement that is enough to write a strong stroke in the history of materials science, even if it takes him to devote his whole life, what's the problem?

With the goal of graphene, Nie Sen is not interested in the speech he is about to give at the annual meeting of materials. In his opinion, the research he has done before is simply trivial, not worth mentioning. Only graphene is so big. The subject is the stage where he can prove his strength.

On the second day, the International Materials Annual Conference was grandly opened in the academic hall of the Ecole Normale Supérieure in Paris. Materials science experts from dozens of countries around the world gathered together and exchanged major achievements in the field of materials science in the past year.

At this annual meeting, the most eye-catching one was the keynote speech given by Jing Jing, a graduate student in the Department of Physics of Jingcheng University. She introduced the discovery of iron-based superconducting materials and the analysis of superconducting mechanism.

Thanks to Qin Hai's guidance, Ning Jing did not hesitate to study the superconducting characteristics of iron-based materials. After hundreds of attempts, she finally found the correct formula and discovered the superconductivity of lanthanum-iron-arsenic-oxygen materials. characteristic. Later, with the help of her supervisor Chen Zongze and other students, she continued to improve the formula, raising the superconducting critical temperature of iron-based materials to 50K.

Once this achievement was released, it immediately caused an uproar in the field of superconducting materials. Superconducting laboratories all over the world joined in this research, and successively proposed more than a dozen different iron-based superconducting materials. The corresponding theoretical research is also Great results.

Due to the great prospects shown by iron-based superconductivity, this year's material annual meeting will promote it as an important content. As the first scholar to discover the superconductivity of iron-based materials, Ning Jing won the honor of giving a keynote speech on this issue. She is said to be the youngest keynote speaker since the inception of the Materials Annual Conference.

When she first got the invitation to the Material Annual Conference, Tranquility was panicked and tried her best to ask Chen Zongze to give this speech. Chen Zong, after a little thought, rejected Tranquility's kindness and encouraged Tranquility to accept the arrangement of the Materials Society. Chen Zong naturally knew what an honor it was to be able to give a keynote speech at the Society for Materials Science and Technology, and this honor was beyond reach for him. However, in the face of temptation, Chen Zong still chose to give up and did not compete with his students.

Regarding Chen Zongze's humility, Qin Hai has different ideas. He felt that Chen Zong did this not only because of his integrity, but also because he feared Qin Hai. Everyone can see that the discovery of iron-based superconductivity is a generous gift from Qin Hai to Ning Jing, whose purpose is to make Ning Jing famous all over the world because of this discovery. Without Qin Hai's instructions and financial support regardless of cost, how could Tranquility persist in such a research without warning and finally achieve a breakthrough.

Tranquility is Chen Zongze's student, if there is no such a relationship as Qin Hai, it is reasonable for Chen Zong to assign Tranquility's achievements to his own name, and no one can say anything gossip. However, with Qin Hai backing Tranquility, Chen Zong would feel a little guilty if he wanted to grab this honor again, so he might as well be more magnanimous and let Tranquility's honor be returned to her.

Tranquility did not expect so many twists and turns. As a student who has just stepped into the field of scientific research, she has not yet fully realized how important a qualification for a keynote speech is. In this circle, how many recognized academic experts have never had the opportunity to give a keynote speech in their entire lives, but she is just a 24-year-old graduate student, and she was able to walk on this red carpet.

"We found that the most direct and easiest way to achieve higher transition temperatures is to synthesize a unit cell containing multiple layers of iron-arsenic, which is similar to the superconducting mechanism in cuprate superconductors. In both systems, the upper critical field is very high, resulting in a strong pairing potential, while the superfluid density is very low..."

Tranquility pointed at the slides on the big screen with a laser pointer, talking eloquently.

When she first stepped onto the podium, seeing so many gray-haired university students in the audience, she really felt a bit of stage fright. But then she saw Qin Hai who was sitting in the front row, and saw the look of encouragement in Qin Hai's eyes. She tried her best to calm herself down, and began to tell the story according to the content that had been rehearsed many times in advance. As the content of the narration gradually unfolded, she gradually forgot her fear and began to enter the academic space she was familiar with. In this space, she has wandered for several years, enough to control everything in it.

"Wow, boom!"

The applause rang out like thunder, and the tranquility immersed in academics suddenly returned to reality. Only then did she realize that she had unknowingly finished the entire speech, and the scholars were applauding her enthusiastically.

"Very good, Ms. Ning, your presentation is perfect, and the theoretical model you put forward is as beautiful as your own." The host of the meeting stepped forward, extended his hand to Tranquility, and expressed his congratulations.

"Thank you, Professor Germer, thank you." Tranquility said excitedly while shaking hands with the host in a panic. This Professor Gemmer is a leading figure in the academic world that she has admired for a long time. To be able to meet him on such an occasion today, and to be able to shake hands with him and accept his congratulations to her, Tranquility really feels flattered.

"Miss Ning, I really want to know, how did you come up with the idea of ​​researching the superconducting characteristics of iron-based materials? To be honest, my assistant and I have also tried to study iron-based materials, but no progress has been made, so we are very excited. You almost gave up. But you can persist in this direction until you pick this pearl, what kind of belief is it based on?" Professor Gemmer asked Tranquility with a smile.

"My supervisor, Professor Chen Zongze, has been doing research on quasi-two-dimensional materials with a hierarchical tetragonal structure, and speculates that there may be a superconducting property that we don't understand in this structure. What we proposed this time Lanthanum Fe Arsenic Oxygen is exactly such a structure. The discovery of this material has verified Professor Chen’s conjectures for many years. Of course, I was able to persevere in the research of iron-based materials despite repeated experimental failures. Thanks to my friend Mr. Qin Hai’s support for me, he encouraged me to continue in this direction, not to give up halfway.” Tranquility said this, and cast her eyes on Qin Hai.

Gemo followed his tranquil gaze and saw Qin Hai. He pretended to be surprised and asked, "Miss Ning, are you talking about this young man? God, I don't think he's old enough." Da, what makes him have such wise eyes?"

Qin Hai had already stood up at this moment, smiling slightly at Germer. In the previous life, he had known this professor Gummer who had a sense of humor. At that time, he was used to calling him "Old Man Gummer", and Gummer accepted it with pleasure. However, in this life, Gemo didn't know who Qin Hai was, but he was somewhat interested in him because he supported Tranquility's research.

"Young man, would you like to come to the stage and introduce your thoughts to everyone?" Gemo asked Qin Hai. In fact, he didn't expect Qin Hai to make some academic explanations, he just regarded this interaction as a small tidbit in the meeting.

"Very willing." Qin Hai readily agreed without any shyness. He walked up the steps to the podium, took the microphone handed to him by Gummer, and said loudly to the audience in fluent English: "Dear ladies and gentlemen, hello everyone, I am very glad to have this An opportunity to meet everyone. My name is Qin Hai, and I am the chairman of China Daqin Industrial Group. Simply put, I am a businessman. Of course, I have another identity, which may be related to this material annual meeting, that is ..."

Speaking of this, he smiled secretly, then pulled Ning Jing who was standing beside him, put one arm around her shoulder, and proudly said to the audience: "I am Miss Ning Jing's fiance!"

"Aw!"

The whole meeting place immediately boiled up, everyone laughed and clapped desperately, expressing their congratulations to the young couple. Most of the participants were Western scholars, and Westerners have always been very open to this kind of public display of affection, and they are also very keen on booing.

"Miss Tranquility, please allow me to congratulate you again. I have to say that your fiancé is a very handsome and charismatic young man. You are really an enviable couple." Germer walked up Go ahead, said enthusiastically.

"Thank you, Old Man Gemo." Qin Hai said to Gemo with a smile.

"What did you call me?" Germer asked in surprise. The name Old Man Gemmer is only used in a very small circle, and people outside the circle have never mentioned it. He doesn't know how this young man from China knows his nickname.

"You are old man Gemmer, aren't you?" Qin Hai repeated with a smile, while looking at Gemmer with mocking eyes. He's not afraid that Germer will check his old background. If you have the ability, you can go to the Space-Time Administration?
