CC, the fastest update material empire!

Chen Zongzhi is currently studying the cerium copper oxygen superconducting material, known as copper-based super material.

The basic design ideas of such materials are through doped other elements, such as yttrium, ,, and so on.

The copper-based superconducting material has been in the world, and it has quickly broken through the 77K liquid nitrogen boots, which caused the boom of superconducting applications in liquid nitrogen.

However, the fatal weakness of copper-based superconducting is that the copper oxide is essentially a ceramic material, lacks toughness and ductility, and the mechanical properties are extremely poor.

This weakness has a considerable difficulty of preparing the copper-based superconducting material, especially when making a linear or strip-shaped material, must be used as a substrate by means of other tough materials.

Further, although the maximum critical temperature of the copper-based superconducting material has reached 135K under normal pressure, 164K under high pressure conditions, but the distance between 300K is much farther than the difference.

The most important thing is that scientists believe that 164K may be close to the highest theoretical upper limit of copper-based superconducting materials.

In other words, don't look at the development of copper-based superconducting, but if the final goal is to be superconducting room temperature, the copper-based material can be considered to wash sleep.

In addition to copper-based materials, scientists have also studied boride magnesium and organic superconducting materials, but progress is also very slow, especially in theory.

In the past few years in the 21st century, superconducting research seems to have entered a dead end, it is difficult to find new directions.

At the beginning of 2008, Japan Xiye Xixiong Research Group reported that 26K superconductivity was observed in fluorine-doped lanthanoxic compound, and China scientists who have explored new superconductors in a similar structural system have been quickly used. , Ruthenium, ,,,

Thereby, the gate of the iron-based superconducting material is pushed.

The discovery of iron-based superconducting materials is another ** discovery of superconducting research.

Although the iron-based superconducting material has not broken through the 77K liquid nitrogen temperature zone, the scientists believe that the scientists believe that the future room temperature superconducting material is very likely to be superchard. Birth of the material.

Qin Hai is very familiar with this scientific history. Since there is a chance to come, he will not refuse to give the honor of the discovery of iron-based superconducting materials to their own people.

Moreover, he hopes to increase the critical temperature of the iron-based superconducting in his own hand to room temperature, thus finalizing a hundred years of room temperature superconducting problems.

I heard the four words of the iron-based superconducting, quietly frowned, said: "Qin Hai, you are a big mistake, according to BCS superconducting theory, it is impossible to have magnetic substances Have high temperature superconductive.

Iron is a typical magnetic element. When we design superconducting materials, we will try to avoid the existence of iron elements.

Qin Hai smiled: "Who tells you that the BCS superconducting theory must be correct? Or, who tells you that there is only one superconducting mechanism? I don't tell you how I consider this principle, but I can suggest that you try to use different elements to dopate arsenic compounds, I guess you can observe the superconducting properties in it.

Within a few years, scientists have found hundreds of iron-based superconductors, more people estimated that the number of members of the iron-based superconducting family can reach more than 3,000.

In this case, Qinhai does not have to directly tell the future of the Japanese experimental ideas. He just pointed out this direction, it will be a misunderstanding that it will hit it.

"It's strange, brother, how do you confuse this?"

Qin Shan turned his head and looked at my brother. I asked curiously.

When reading in secondary school, she only knew that although this brother did not have high school, she was familiar with high school knowledge, she could give her and many precise guidance.

After the university, she found that her brother was so simple that his homework is so simple. He is almost as directed by the development trend of material technology. If you give you a thinking, you can make a very good article.

If the guidance of high school can also use learning to conscientiously explain, now these guidance on scientific research can only be described with ghosts.

Fortunately, whether Qin Shan is still quiet, under the influence of the subtletime of Qinhai, there are some numbers in this kind of miracle.

Occasionally, it will also be born with nature because it is used to it.

For Qinhai's guidance, the two now the same reaction is to quickly record, and then work in the direction of Qinhai, they know that there will be big fish in this direction.

"Iron Base Superconductance ..."

Quiet patted his forehead, said: "Is this related to the electronic scattering of the hole and electronic Fei rice? Chen Teacher said that in an academic report, he told such a conjecture, but did not have time to do experiment.

Qin Hai, you won't listen to Mr. Chen's report like this? "

"There are people who have this kind of conjecture, I am afraid it is not only one.

Qin Hai smiled and said that there is such a hole, Fei Mi, and other cavities, Qin Hai only knows it, but I don't know how it happened.

He put his hand: "This kind of theoretical issue, you don't have difficulty for my technical school.

You have taken time to do experiments. If there is any problem in theory, I will find Mr. Chen.

However, this idea can be confidential first, in case leak, be known by others, you can't grab the originality.

"You don't ask us to do apply research? How can I have time to do these experiments?"

Quiet, smiling, will have the Qinhai First Army.

Qin Hai Zhengqi: "Doing application research, it is something else.

Hello, is also a major shareholder of the research center, but also doing this unknown thing? "

If you let Zhang Shengying heard this, it is estimated that it is far away from the old blood.

She is a major professor, being forced to do application research, otherwise don't want to lead the experimental material.

Tranquility is such a first grade of Zhibo, actually can enjoy the application, concentrate on the treatment of theory, is there anything that is natural? Sentiants also thought of this, she said: "I don't dare, I will talk to my classmates.

Qin Haidao: "This is not difficult, I told Mr. Chen, let him arrange you to do this new direction.

After the article wrote, let Mr. Chen hang the first author. You hang the author, the interests, and he will not agree.

"If this experiment can really be made, it will completely subvert the traditional superconducting theory, and the Nature on this article really has hope.

If you tell Mr. Chen, he will definitely agree, and even make the strongest human hand to engage in this direction.

Say quiet.

Qin Haidao: "This can't, discovering that Iron-based superconducting this honor, must be yours, can't let others take away.

You can rest assured, others are not easy, the preparation of iron-based materials is much rare than copper-based materials, the cost is much larger, I don't point, others can't get so much funds to engage in sample preparation, so you will go boldly Do it, glory is quiet, I am optimistic about you.

Since you are sure, why don't you do it yourself? Give me such a good idea, are you not a loss? "

Qin Shan smiled and said: "Xiao Jing, you don't leave, my brother is not yours, still in front of me.

"Xiaoshan, isn't you want to eat apple?"

It's peaceful to cut half of the apple threat, but the eyes are secretly went to the Qin Haimen.

Relationship between her and Qinhai, whether it is Qin Shan, Qin Ling, or her own brother Ningn, has been half-joke, half-truth, and there is countless back, but the big wood in Qinhai has never loose I don't know what he thinks.

In fact, when Qin Hai, when I saw the quiet, I was attracted by this beautiful and cheerful girl, otherwise he would not stick to it in those years. Not Chu.

The key is that Qin Hai is a traveler, the previous world has been nearly 30 years old. When I saw quiet, I was 16 years old, and I was a typical green apple, so that Qin Hai how to get a mouth.

It is such a psychological barrier, accompanied by Qinhai for many years.

In order to now, quietly graduated from college, Apple has already attracted the tempting red, and Qin Hai feels that he can accept this temptation.

A few days ago, I went to the superconducting research center. What Hou brother said that many of the cars have been harassed every day, which makes the Qinhai have some crisis, flowers, is it to go to it? When is the serest white? "Xiao Jing, Xiaoshan does not say, I have forgotten it.

Listening to your Hou brother said, this time, there are many people who have opened a luxury car to the research center to find you. What is this? "

Qin Haiyou asked.

The quiet face is red, and it is gently and said: "It is not all some of them to have money, so many brothers who have graduated from our school, and I don't know how to hear my name, just drive the car. Come to make friends with me.

It is said that I have to take me to eat, I have to ask me to watch movies, some are already a uncle in her 30s, and I don't want to be cold.

Yes, there is a person who can laugh at me. He is more fat than my brother. He also told me: Ningshi, like a young man in a jade tree, you have to find it? "

When I said this, she stood up and showed the waist circumference of the person, and then with Qin Shan, laughed to cross.

"The noble is true ..."

Qin Hai also commented on a sentence, then asked: "There is no one you can see."

"What do you say?"

Quiet, staring at the eyes, staring at Qinhai: "Do you especially hope that I can see it in them?"
