Material Empire

Qin Hai left to Nie Sen after explaining the relevant thoughts, leaving Nie Sen alone in the room, frowning, sometimes ecstatic, and couldn't sleep well all night.

It is easy to put forward the concept of graphene, but to prepare a stable graphene sample, there is still a lot of arduous work to be done, which requires several years of hard work. Qin Hai himself is not an expert in graphene. He cannot explain all the technical details to Nie Sen, but can only point out one direction, and then give Nie Sen sufficient authority so that he can fully mobilize manpower and material resources to accomplish this. Cross-century research work.

Nie Sen naturally understands the difficulty of scientific research. In his mind, he feels that if he can complete the tasks delivered by Qin Hai within 10 years, he will be regarded as having achieved merits. Such a scientific research result that is enough to write down a rich and colorful one in the history of materials science, even if it takes him a lifetime of energy, why not?

With the goal of graphene, Nie Sen has no interest in the speech he will give at the annual material conference. In his opinion, the research he has done before is just pediatrics, not to mention, only graphene is a big one. The subject is the stage that can prove his strength.

On the second day, the International Material Conference was grandly opened in the academic hall of the Paris Normal University. Materials experts from dozens of countries gathered together to exchange important achievements in the field of materials science in the past year.

At this annual conference, the most noticeable one was the keynote speech made by the quiet graduate student of the Department of Physics of Jingcheng University. She introduced the discovery of iron-based superconducting materials and the analysis of superconducting mechanisms.

Thanks to Qin Hai's guidance, Tranquility did not hesitate to study the superconducting characteristics of iron-based materials, after hundreds of attempts. Finally found the right formula, discovered the superconducting properties of lanthanum iron arsenic oxygen material. Subsequently, with the help of her mentor Chen Zongze and other classmates, she continued to improve the formula to increase the superconducting critical temperature of iron-based materials to a level of 50k.

Once this result was released, it immediately caused a stir in the superconducting materials industry, and superconducting laboratories around the world joined this research one after another. More than a dozen different iron-based superconducting materials have been proposed successively, and the corresponding theoretical research has also yielded fruitful results.

Because of the great prospects shown by iron-based superconductors. This year's material year will introduce it as an important content. Tranquility, as the first scholar to discover the superconducting characteristics of iron-based materials, won the honor of giving a keynote speech on this issue. She is said to be the youngest keynote speaker since the founding of the annual material conference.

When initially invited to the Annual Materials Meeting, Tranquility panicked. He urged Chen Zong to make this speech. After a few thoughts, Chen Zong rejected the kindness of serenity and encouraged serenity to accept the arrangement of the material society. Chen Zong naturally knows what kind of honor it is to be able to make a keynote speech at the Institute of Materials, which is also beyond his reach. However, in the face of temptation, Chen Zong chose to give up instead of competing with his students.

For Chen Zongze's modesty, Qin Hai had different ideas. he thinks. Chen Zong did so not only because of his high winds and bright festivals, but also because of his fear of Qin Hai. Everyone can see the discovery of iron-based superconductors. It is a great gift from Qin Hai to Tranquility, whose purpose is to make Tranquility famous for this discovery. Without Qin Hai's instructions and no capital support, how could Tranquility persist in such a study without warning and eventually make a breakthrough.

Tranquility is a student of Chen Zongze. If there is no such relationship as Qin Hai, it would be reasonable for Chen Zong to assign the fruits of tranquility to his own name. No one can tell any gossip. However, there is Qin Hai backing behind the tranquility. Chen Zong was going to grab this honor again, and she was a little guilty. She might as well be more generous and let all the honors that belong to the serenity be returned to her.

Tranquility couldn't think of so many twists and turns. As a student who has just stepped into the field of scientific research, she still can't deeply understand how important a qualification for a keynote speech is. In this circle, how many recognized academic bulls have never been given a chance to give a keynote speech in her lifetime, and she is just a graduate student who has just turned 24 and is actually able to embark on this red carpet.

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

Serenity pointed at the slide on the big screen with a laser pointer and talked.

When she first stepped onto the podium, she looked at so many white-haired college students in the audience, and she really felt a bit of a stage fright. But then she saw Qin Hai sitting in the front row and saw the encouraging look passed from Qin Hai's eyes. She worked hard to calm herself down and started to tell the story based on many rehearsals. As the content of the story unfolded, she slowly forgot her fear and began to enter the academic space she was familiar with. She has been in this space for several years, enough to control everything.

"Boom!"

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

"Very good, Ms. Ning, your story is perfect. The theoretical model you proposed is as beautiful as you personally." The conference host stepped forward and extended his hand to Serenity, congratulating.

"Thank you Professor Gemmer, thank you." Tranquility said excitedly, shaking hands with the host. This Professor Gemmer, who she admired for a long time in academic circles, was able to meet on such an occasion today, and was able to shake hands with him and accept his congratulations, which really made tranquility feel flattered.

"Ms. Ning, I would like to know, how did you come up with the research on the superconducting characteristics of iron-based materials? It's true. I also tried to study iron-based materials with my assistants, but no progress was made. You will soon give up. But you can continue in this direction until you pick up this pearl. What kind of conviction is this? "Professor Gemmer asked quietly with a smile.

"My mentor, Professor Chen Zongze, has always studied quasi-two-dimensional materials with hierarchical tetragonal structures, and speculates that there may be a superconducting property in this structure that we do not understand. We proposed this time The lanthanum iron arsenic oxygen is such a structure. The discovery of this material has verified Professor Chen's conjecture for many years. Of course, I can persistently research iron-based materials in the case of failure of many experiments. Thanks to my friend Mr. Qin Hai's support for me, he encouraged me to continue in this direction, not to stop halfway. "Serenity said here, and set his sights on Qin Hai.

Ge Mo followed the quiet eyes and saw Qin Hai, he pretended to be in shock, and asked, "Ms. Ning, are you talking about this young guy? Oh my god, I don't think his age is Great, what made him so savvy? "

Qin Hai stood up at this time and smiled slightly to Ge. In the previous life, he knew this somewhat humorous Professor Germer, at that time he was used to calling it "old Germer", and Germer was also glad to accept it. However, in this life, Gemme didn't know who Qin Hai was, just because he supported the study of tranquility, and was interested in him.

"Young man, would you like to come to the stage and introduce your ideas to everyone?" Ge Mo asked Qin Hai. In fact, he did not expect whether Qin Hai could make some academic explanations. He just regarded this interaction as a trivia of the conference.

"Very willing." Qin Hai did not hesitate and agreed quickly. He walked down the steps to the podium, took the microphone handed to him by Gomer, and spoke loudly to the audience in fluent English: "Dear ladies and gentlemen, hello everyone, it is a pleasure to have this A chance to meet everyone. My name is Qin Hai and I am the chairman of China Daqin Industrial Group. In short, I am a businessman. Of course, I have another identity, maybe related to this material conference, that is ... "

Having said that, he smiled mysteriously, and then pulled the tranquility standing next to him, and wrapped her shoulders with one hand ~ www.readwn.com ~ said proudly to the audience: "I am Miss Peace fiancé!"

"Oh!"

The whole venue suddenly boiled, everyone laughed, applauded desperately, and congratulated the young people. Most of the attendees were Western scholars. Westerners have always been very open-minded about this kind of show and love, and they are also very keen to coax.

"Miss Tranquility, please allow me to congratulate you again. I have to say that your fiance is a very handsome and charismatic young man. You are an enviable pair." Go forward and say enthusiastically.

"Thank you, old Germer." Qin Hai said to Germer with a smile.

"What do you call me?" Gomer asked in amazement. The name Old Man Gemmer was used in a very small circle. People outside the circle never mentioned it. He didn't know how this young man from China knew his nickname.

"You are the old man of Gemmo, aren't you?" Qin Hai repeated with a smile, while looking at Gemme with ridiculous eyes. Isn't he afraid that Gemmer will check his boss, you can go to the Space and Time Administration if you have the ability? (To be continued)
