"I need the cooperation of two real rooms. ”

Hu Wenhai's sudden appearance surprised Director Song. However, he was followed by Ni Guangnan and Ling Xiao, and he could still do it when he walked into the office of the director of the Science and Technology Commission.

Unlike Hu Wenhai, who is lazy in brushing his face in the academic world, Ni Guangnan is like a new student in the domestic semiconductor industry with his achievements in Lenovo Hanka and the achievements he has made in the past two years.

As for Ling Xiao, although his age is not too old, his reputation abroad is not small. Hu Wenhai published the principle of three generations of water lithium battery in his name, which made him have a lot of prestige in the international electrochemical community.

With these two King Kong protectors, Hu Wenhai is not like entering a no-man's land in the Science and Technology Commission, at least he can do it with a light car.

Director Song frowned and looked at the young Hu Wenhai, who was a little excessive: "Comrade Xiao Hu, the problem between us was a misunderstanding before, and I already know this situation." ”

Although Xiao Yeqin was squeezed enough on the phone, Director Song was not very angry or resentful.

On the one hand, Xiao Yeqin, as a former front-line researcher, has this position to accuse the higher-ups of not doing a good job - other researchers may not have these ideas, but they still have to mingle in this circle and eat this mouthful, so they can't speak too casually.

Since Xiao Yeqin doesn't serve your job, she naturally has the capital to speak according to her mood.

In the second aspect, what Xiao Yeqin said is also true. Although some problems do not have the root cause of the Science and Technology Commission, the scope of solving some problems exceeds the power of the Science and Technology Commission, and some problems are easier said than done. But if there is a problem with today's scientific research system, even Director Song himself does not deny this.

It's just that the current status quo of the country is like this, and it is not possible for Director Song or even the Science and Technology Commission to change the general trend.

Director Song's self-cultivation is still very good, and some of Xiao Yeqin's accusations are explained as much as he can, while others can only be silent. But to say that he has resentment or hostility towards Xiao Yeqin or Hu Wenhai because of this, it would be too underestimated to underestimate him.

Since the current situation was created by Xiao Yeqin, Director Song naturally wouldn't mind the little unpleasantness before.

"Sit down, all three of you. Director Song greeted Hu Wenhai, Ni Guangnan and Ling Xiao, and smiled: "Let's not talk about the previous unhappiness, Comrade Xiaohu's level is very rare in my opinion." Do you want to borrow two real yàn rooms? What do you want to do? What kind of real yàn rooms do you need?"

Hu Wenhai said simply: "The materials science project, the solid state physics room, must have the ability to study microstructure. ”

"Oh?" Director Song looked a little curious: "What kind of research is it, can you tell me about it?" ”

Hu Wenhai groaned slightly, nodded and said, "There is nothing to hide from Director Song, I plan to make two real things." One is that the resistivity of magnetic materials may change dramatically when there is an external magnetic field compared with that without an external magnetic field. ”

Director Song couldn't help but sit up straight, looked at Hu Wenhai and frowned: "Is there such a material in the world now?"

Hu Wenhai stretched out his hands: "If there is such a material, I don't need to be real." ”

"Is it possible to realize this material?" Director Song frowned, as if he was trying to think: "If there is really such a material, it means ......"

This means that the capacity of computer hard disks can be greatly expanded, from the current unit of m, to the unit of g or even t. The capacity of computer hard disks will increase by thousands of times. ”

Hu Wenhai's expression was indifferent, as if he was saying the most clear facts.

Of course, this is also true.

The technology that Hu Wenhai said was used by any hard disk in later generations. This technology, called the "giant magnetostrictive head", was the basis for the computer hard disk to be able to go from a room full of cabinets in the 80s to the hard drive that people held in their hands. The principle of the giant magnetoresistance effect won the Nobel Prize in Physics in 2007.

Director Song was able to become the director of the Science and Technology Commission, and naturally he had an extremely keen sense of smell for the development of science and technology. Hu Wenhai's speculation, after a short period of thinking, he immediately realized the value and significance of the benefits of giant magnetoresistance.

Hu Wenhai glanced at Ni Guangnan and nodded slightly.

Ni Guangnan then stood up and said: "Old Song, if the benefits of giant magnetoresistance do exist, and China can develop a new generation of computer hard disks based on this, then it will have an immeasurable effect on the development of China's computer industry." With this as a springboard, perhaps China's computer industry will be able to seize the opportunity and strive to enter the international arena. We should establish our own standards and use various means of technology exchange to extricate China's computer industry from the situation of being controlled by others, or at least break the current international embargo on high-performance computers. ”

The miniaturization and high density of storage devices mean that the cost of social information storage is reduced, and it is an indispensable piece of the technical puzzle to promote the information society. Of course, although China does not have the foundation of information technology at present, the United States, Japan, Europe, and other developed countries are quietly prevailing in the international community to refer to the information industry and information society.

Information is no longer just a description of the real world, but a kind of knowledge that can create value and exchange. Information and knowledge will become the decisive factors affecting productivity, competitiveness and social economy, in other words, information creates value in the exchange of information society.

A device capable of storing a large amount of information is equivalent to a vault, and giant magnetoresistance technology is undoubtedly the key to this vault. One can imagine how attractive this technology will be to those computer companies.

"Oh, Comrade Xiao Hu has confidence in this truth?" asked Director Song as he cheered up and straightened his back.

"Of course, if I didn't have confidence, I wouldn't have come to Director Song for help. Hu Wenhai smiled and nodded confidently.

"Okay, let me think about it!"

Director Song closed his eyes and pondered for a long time, then opened his eyes and said: "The Institute of Metal Materials of the Chinese Academy of Sciences is in Shengjing, and they have a solid atomic image research institute, which is very good in the microscopic research of metal materials. Since it is a magnetic and non-magnetic metal material with a thin film structure, the level of this research institute can still be trusted. ”

"Okay, that's this institute!" Hu Wenhai immediately nodded and agreed without saying a word.

Director Song looked at Hu Wenhai with great interest, and asked with a smile: "Then what about the second item?

"The second item is still in materials science. Hu Wenhai did not sell it, and said directly: "I plan to realize the two-dimensional crystal of carbon at room temperature." ”

"Huh?!"

Director Song snorted and stood up directly. He looked at Hu Wenhai, frowned and subconsciously retorted: "The two-dimensional crystal of carbon? The two-dimensional crystal is thermodynamically unstable, and the thermal disturbance at a finite temperature will destroy its long-range order, so that the perfect two-dimensional crystal will follow the fluctuation and the area is proportional to the area under the thermodynamic fluctuation. Once the Chiral symmetry break occurs in the vicinity of the bandgap node, the Dirac fermions will gain an effective mass and produce a non-zero bandgap, so that the Co dew MB force cannot bind the atom ......"

Hu Wenhai simply raised his hand, nodded and said, "Director Song, I also understand what you said, but you forgot one thing." Science is used to explain reality, not that reality should conform to scientific theories. The existence of two-dimensional carbon crystals is easy to verify, and if it turns out that I am wrong, I would love to hear you explain the truth in this. But now, I hope to ask Director Song to help me verify whether I am whimsical and whether this new material I call graphene can really exist. ”

Director Song was condescending and stared at Hu Wenhai for a long time. Hu Wenhai looked at Director Song generously, and he didn't have a weak heart at all.

"Director Song, I want to say something. ”

Ling Xiao raised a finger: "The Battery Research Institute of the New Academy of Sciences is developing a lithium iron phosphate lithium-ion battery, and the performance of this battery can even greatly surpass the first and second generation of lithium water batteries in all aspects." Its energy density, charging speed and safety are all revolutionary improvements compared with lithium metal batteries. However, although the charging time has also been improved, it still requires a relatively short process. If graphene materials can really be realized, the new rechargeable batteries produced with lithium-ion battery technology will not even charge much faster than the time it takes to add gasoline to the car. If this technology can be realized, I don't need to explain how much it means, right?"

After listening to Ling Xiao's words, Director Song sat back on the sofa like a deflated ball.

"Okay, let's try it. He nodded, thought for a long time, and then continued: "The newly established Institute of Solid State Physics of the Chinese Academy of Sciences is considered to be the top level in China in terms of nanomaterials, and this real thing can be handed over to them." ”

"Okay!" Hu Wenhai stroked his palms and smiled, nodding at Ni Guangnan and Ling Xiao.

The two took out two copies of the actual plan and put them in front of Director Song.

"Director Song, if it's okay, I'll leave first. If there is a result, please do your best to inform me. Hu Wenhai clapped his hands, stood up, said goodbye to Director Song, and walked out of his office.

Director Song looked at the three of them, and his eyes fell on the two practical plans on the table.

It occurred to him that if both of these realities could succeed--

This Hu Wenhai, uh, shouldn't have come up with these two real plans just to support his mother, right?
