Qin Hai finished explaining his thoughts to Nie Sen and left, leaving Nie Sen alone in the room, sometimes frowning, sometimes ecstatic, and not being able to sleep soundly for a whole night.

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

Nie Sen naturally understands the difficulty of scientific research, and in his mind, he feels that if he can complete the task delivered by Qin Hai in 10 years, it will already be considered a complete merit. What does it matter if such a scientific achievement, which is enough to write a strong mark in the history of materials science, even if it costs him a lifetime?

With such a goal of graphene, Nie Sen has little interest in the speech he is about to make at the annual meeting of materials, in his opinion, the research he has done in the past is simply pediatrics, not worth mentioning, only the big topic of graphene is the stage that can prove his strength.

On the second day, the International Materials Annual Conference was grandly opened in the academic hall of the École Normale Supérieure in Paris, where materials science experts from dozens of countries around the world gathered to exchange important achievements in the field of materials science in the past year.

At this annual meeting, the most eye-catching thing was the keynote speech made by Jing Jing, a graduate student of the Department of Physics of Beijing University, who introduced the discovery of iron-based superconducting materials and the analysis of superconducting mechanisms.

Due to Qin Hai's guidance, Tranquility did not hesitate in the study of the superconducting characteristics of iron-based materials, and after hundreds of attempts, he finally found the correct formula and discovered the superconducting properties of lanthanum-iron-arsenic oxide materials. Subsequently. With the help of her mentor Chen Zongze and other classmates, she continued to improve the formula, so that the superconducting critical temperature of iron-based materials was raised to the level of 50K.

As soon as this result was released, it immediately set off an uproar in the superconducting materials community, and superconducting laboratories around the world have joined the research, and more than a dozen different iron-based superconducting materials have been proposed. The corresponding theoretical research has also achieved remarkable results.

Because of the great promise of iron-based superconductivity, it was promoted as an important part of this year's Materials Annual Conference. As the first scholar to discover the superconductivity characteristics of iron-based materials, Tranquility was honored to give a keynote speech on this issue. She is said to be the youngest keynote speaker since the inception of the Annual Meeting of Materials.

When she first received the invitation to the annual meeting, Tranquility was terrified and tried her best to ask Chen Zongze to give this speech. After a little thought, Chen Zong rejected Tranquility's kindness and encouraged Tranquility to accept the arrangement of the Materials Society. Chen Zong naturally knows what an honor it is to be able to give a keynote speech at the Materials Society. This honor is also unattainable 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 had different thoughts. He felt that Chen Zong did this not only because of his high spirits, but also because of his fear of Qin Hai. Everyone can see the discovery of iron-based superconductivity. It was a generous gift from Qin Hai to Tranquility, and its purpose was to make Tranquility famous all over the world because of this discovery. There is no Qin Hai's instructions and financial support regardless of the cost of work. How could Serenity persist in such a study without warning and finally make a breakthrough.

Tranquility is Chen Zongze's student, if there is no such relationship as Qin Hai, it is reasonable for Chen Zongze to assign Tranquility's achievements to his name, and no one can say any gossip. However, there is Qin Hai behind the tranquility. Chen Zong wants to snatch this honor again, he will be a little weak-hearted, it is better to be more generous and generous, and let all the honors that belong to Tranquility be returned to her.

Tranquility couldn't have imagined so many twists and turns, as a student who had just stepped into the field of scientific research. She still can't really appreciate how important a keynote speech qualification is. In this circle, how many recognized academic bulls have never been able to get the opportunity to give a keynote speech once in their lives, and she is just a 24-year-old graduate student who can walk on this red carpet.

"We found that the most straightforward and easiest way to obtain a higher transition temperature is to synthesize a single cell containing multiple layers of iron and arsenic, which is similar to the superconducting mechanism in copper oxide superconductors. In both systems, the upper critical field is very high, resulting in a strong pairing potential, while the superflow density is very low......"

Tranquility pointed at the slides on the big screen with a laser whip and talked eloquently.

When she first stepped onto the podium, she really felt a little stage fright when she saw so many gray-haired university scholars in the audience. But then she saw Qin Hai sitting in the front row, and saw the look of encouragement in Qin Hai's eyes. She tried to calm herself down and began to tell the story as she had rehearsed many times beforehand. As the narration unfolded, she slowly forgot about her fears and began to enter the academic space she was familiar with. In this space, she has been wandering for several years, enough to control one of them.

"Whoa!"

The applause rang out like thunder, and the tranquility immersed in academics suddenly returned to reality. Only then did she realize that she had unconsciously finished the entire lecture, and the scholars were encouraging her with enthusiastic applause.

"Very good, Miss Ning, your presentation is perfect, and the theoretical model you have proposed is as beautiful as your own." The moderator stepped forward and extended his hand to Tranquility in congratulations.

"Thank you, Professor Gemmer, thank you." Tranquility said excitedly while shaking hands with the host in a panic. This Professor Gemmer was an academic champion she had admired for a long time, and it was really flattering to be able to meet him on such an occasion today, and to be able to shake hands with him and accept his congratulations on her.

"Miss Ning, I'm curious to know, how did you come up with the idea of studying the superconductivity characteristics of iron-based materials? Truth be told, my assistant and I tried to work on iron-based materials, but we didn't make any progress, so we quickly gave up. And you can continue to do it in this direction until you pick this pearl, what kind of belief is this? Professor Gemmer asked Serenity with a smile.

"My supervisor, Professor Chen Zongze, has been studying quasi-two-dimensional materials with hierarchical tetragonal structures, and speculated that there may be a superconducting property in this structure that we do not understand. The lanthanum iron arsenic oxygen we proposed this time is just such a structure, and the discovery of this material has verified Professor Chen's conjecture for many years. Of course, I was able to persevere in my research on iron-based materials despite many failed failures, thanks to the support of my friend Mr. Qin Hai, who encouraged me to continue in this direction and not give up halfway. Speaking of this, Tranquility set his eyes on Qin Hai.

Following Tranquility's gaze, Ge Mo saw Qin Hai, he pretended to be surprised, and asked, "Miss Ning, are you talking about this young man?" Oh my God, I don't think he's very old, what makes him have such a wise eye? ”

Qin Hai had already stood up at this time, smiling slightly at Xiang Gemo. In his previous life, he had known Professor Gemmer, who had a bit of a sense of humor, and at that time he was accustomed to calling him "Old Man Germer", and Gemer was happy to accept it. However, in this life, Gemo didn't know who Qin Hai was, but he was only interested in him because he supported Tranquility's research.

"Would you like to come up to the stage and tell everyone what you think?" Gemo asked Qin Hai. In fact, he did not expect Qin Hai to be able to make some academic explanations, he just regarded this interaction as a small tidbit at the meeting.

"Very willingly." Qin Hai was not hesitant and readily agreed. He walked up the steps to the podium, took the microphone handed to him by Germer, and said loudly to the audience in fluent English: "Ladies and gentlemen, dear ladies and gentlemen, it is a pleasure to have such an opportunity to meet you. My name is Qin Hai, and I am the chairman of China Daqin Industrial Group, and to put it simply, I am a businessman. Of course, I also have another identity, perhaps related to this annual meeting of materials, and that is ......"

Speaking of this, he smiled secretly, then pulled Tranquility who was standing next to him, put one hand around her shoulder, and said proudly to the audience: "I am Miss Tranquility's fiancé!" ”

"Whew!"

The whole venue immediately boiled over, and everyone laughed and applauded desperately, congratulating the young couple. Most of the participants were Western scholars, and Westerners have always been very open to this kind of public show of affection, and they are also very keen to coax.

"Miss Tranquility, 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." Gemmer stepped forward and said enthusiastically.

"Thank you, old man Gemmer." Qin Hai said with a smile to Ge Mo.

"What do you call me?" Gemmer asked, surprised. The title Old Man Gemer was used only in a very small circle, and no one outside the circle had ever mentioned it, and he did not know how this young man from China knew his nickname.

"You're Old Man Gemmer, aren't you?" Qin Hai repeated with a smile while looking at Gemo with a mocking gaze. He's not afraid that Gemer will check on his old bottom, if you have the ability, you can go to the Time and Space Administration? (To be continued......)
