Great Country Academician

Although he had some doubts about whether these two very young female assistants could do a good job in this job, they were all selected and brought here, and it was not easy for Xu Chuan to tell him in person that he should be replaced with a male one.

No matter how you use it, let's use it for a while and then look at it.

After thinking for a while, Xu Chuan decided to get a private email or phone number in the future.

Having an assistant is a good thing, but sometimes it is not very convenient in some ways, especially in some personal communication and so on.

For some project or public matters, it is no problem for the assistant to take the place of preliminary processing.

But when it comes to some personal matters, it is better for him to come in person.

Thinking of this, Xu Chuan suddenly remembered another thing.

When he was in Beijing before, he met Lu Tianrui, an old friend of Xingcheng No. 1 Middle School by chance at Peking University, and agreed to send him some previous study books when he came back, but he forgot about it when he got busy later.

Coincidentally, two new assistants have been recruited now, and they can go to the villa to get all the books he had in Princeton.

On the one hand, it is sorting out, copying some books and sending them to Lu Tianrui.

On the other hand, it can be used as learning materials for these novice students according to the classification. Although for graduate students and doctoral students, those books are slightly beyond the scope, but it does not matter, as long as they are useful.

After all, reading some books that are slightly beyond the scope can help the brain to think.

After arranging the work, Xu Chuan checked the homework of the two students, and then set off for Chuanhai Materials Research Institute.

Applying the strong diamagnetic mechanism of KL-66 material to other superconducting materials requires his perfect mathematical method, but also requires the computational mathematical model in the Chuanhai Institute of Materials.

In addition, he hasn't been to the research institute for a while.

Although someone is managing it for him, as the boss, he still needs to know about the work situation and progress of the institute.

All the way to the research institute at the foot of Zijin Mountain, Xu Chuan successfully contacted Fan Pengyue in advance.

Now the master bear is busy in the laboratory.

Seeing this scene, Xu Chuan became a little curious, and asked with a smile: "By the way, why did you suddenly go to the laboratory in person?"

Although the master Xiong himself came from the laboratory and did many experiments with Chen Zhengping, since he managed the Chuanhai Materials Research Institute, he rarely had the opportunity to be an experimental ape in the laboratory.

"Graphene!" Wearing a white coat, Fan Pengyue replied excitedly: "We have found a method to synthesize high-quality graphene in batches! We are doing the final experiment. If it is feasible, this will be the biggest revolution in the material industry!"

Hearing this, Xu Chuan was stunned for a moment, walked forward quickly, and asked, "When did it happen, why didn't you hear the report?"

"Wait a minute, I'll finish this step." Fan Pengyue said without turning his head, staring at the equipment.

Hearing this, Xu Chuan waited patiently.

If high-quality graphene materials can be synthesized in batches to achieve industrial production, it will be one of the biggest changes in the material industry, as the master Xiong said.

Yes, one of them, not the only one.

In fact, compared with other researchers or scholars in the field of materials, his attitude towards graphene is not so fanatical.

Although he is also very optimistic about this new type of material, he believes that it has great potential in the future, and even used graphene when studying high-temperature copper-carbon-silver composite superconducting materials before.

But compared to others, he is calmer.

Graphene has been hailed as the "king of new materials" by the materials science community.

Extremely high strength, high electrical conductivity, high thermal conductivity, ultra-thin, high transparency, high flexibility, high chemical stability, magnetic... and other excellent physical properties in various aspects, endowing it with a wide range of adaptability.

From various basic raw materials to cutting-edge fields such as new nanomaterials, high-performance electronic devices, energy storage conversion, medical biology, etc., graphene is suitable for all.

But it's not without its drawbacks.

For example, it is often said that high-quality products are difficult to produce, easy to oxidize in the air, and special packaging is required for the use environment.

Apart from these general shortcomings, graphene's biggest problem is actually not here.

The biggest problem with graphene is that its performance on paper is extremely good, but its application performance is actually very average.

Yes, extremely high strength, extremely high electrical conductivity, extremely high thermal conductivity, etc. are the advantages of graphene, but what no one has ever told the world is that these advantages almost only exist in the laboratory or microcosm level.

Those extremely excellent properties either only exist on PPT paper, or only exist in the laboratory, or can only be possessed by very perfect graphene.

For example, the mechanical properties, the excellent mechanical properties of graphene must have been heard by everyone, surpassing steel.

But what no one told you is that the purity of graphene is extremely high and requires a special assembly process.

With conventional manufacturing, the mechanical properties of superimposed graphene become almost the same as that of graphite. In this respect, carbon fiber materials are currently stronger, and it can even be said to kill graphene.

No way, the current graphene simply cannot achieve the mechanical properties on the PPT.

Or in terms of batteries, the capacity of graphene batteries has been blown loudly in the past, comparable to lithium air and stronger than lithium sulfur.

However, in fact, graphene materials have high chemical reactivity and are prone to lose stability in electrochemical reactions, which will lead to problems such as decreased capacity of electrode materials and shortened battery life.

Of course, if these problems can be solved in the future, graphene can indeed be called the "king of new materials".

As for now, the future still needs to see development.

However, for Xu Chuan, if the Chuanhai Materials Laboratory can find a way to mass-produce high-quality graphene, it will be quite impressive.

At least, there is currently no way to industrially produce graphene in the world, and the gap is huge.

If it can be marketed in batches, graphene can bring him a market of at least billions of meters of gold every year.

In 2019, the global output of graphene was only 1,200 tons in all countries.

Compared with the demand for graphene in the global market, this figure is not even a drop in the bucket.

And in terms of graphene research, he can also seize the opportunity.

After all, the cost has come down, and naturally some people are willing to continue investing in it.

After waiting for a while, Fan Pengyue finished manipulating the steps in his hands, and handed over the follow-up experiments to his assistant.

"What's the situation? Why did you suddenly break through?" Looking at Master Xiong who took off his experimental gloves and came over, Xu Chuan asked curiously.

Fan Pengyue smiled, and replied mysteriously: "I have to thank one person!"

"who?"

"Your primary school sister."

"Liu Jiaxin?" Xu Chuan was stunned for a moment, and asked in surprise, "How did the graphene breakthrough have anything to do with her?"

Fan Pengyue smiled and said: "After she came back last year, didn't you ask her to help build a safety protection platform for Chuanhai Materials Institute. Because of the need to communicate with the institute, she often comes here to discuss."

"In the second half of this year, when studying the rapid synthesis graphene circuit discovered in 2019, the institute encountered some difficulties. She helped to re-optimize and design the material model for this piece."

"Then through the model, we have recently found a feasible path, which has been verified by supercomputing and computing models, and production is feasible."

"So the entire graphene department is currently working overtime to do experiments, and I have no time to integrate materials and report to you."

"But if you don't come, it's almost time for me to contact you in the next two days."

Xu Chuan suddenly nodded and said, "So that's the case."

Fan Pengyue asked curiously: "Speaking of which, what is your relationship with that primary school girl? Can you ask her to help you?"

"What help?" Xu Chuan asked curiously.

"Ask her to help optimize the material calculation model." Fan Pengyue said: "You know, as more and more material mechanism data are added, the volume of the model you made before will become larger and bloated."

"In fact, it is quite huge now, and every calculation requires a huge amount of computing power. If it weren't for the huge computing power provided by the newly built supercomputer at Nantah University, the institute would not be able to support it. of."

"And the computing power of Nantah University's supercomputing is also limited, and it is impossible for the school to allocate all the computing power to us. If we continue to expand like this, I am afraid that we will only have to build our own supercomputing path."

"Although the research institute is already trying its best to optimize it, its capabilities are limited after all. Coupled with the complexity and high confidentiality of this thing, it is difficult for us to recruit suitable personnel to optimize it."

"Speaking of which, your elementary school sister is really strong in mathematical modeling. I feel that you are afraid that you will not be able to compare with her in this regard."

"The graphene computing simulation module we are using now is the architecture she helped to reset, which is about 170% higher in computing performance than the one we wrote before."

"That's why I want to ask her to help re-optimize the overall structure."

Xu Chuan nodded, and said, "I'll ask about this later, and we should indeed do something about optimizing the architecture."

After a pause, he continued: "But now you and I will talk about graphene first. How did you mass-produce it?"

Compared with optimizing the computational material model, Xu Chuan is more curious about how the mass production of high-quality graphene is achieved.

You must know that this thing hadn't been fully industrialized before he came back from rebirth. The difficulty can be seen, which is quite large.

PS: Yesterday's second update was a little late, sorry, today is also at least the second update! Ask for a monthly pass, it’s the end of the month, let’s vote for the monthly pass in the hands of the bosses, thank you Yao (●''●)
