Although there was some doubt whether these two very young female assistants could do the job well, they had already been selected and brought over, and Xu Chuan could not tell him face to face that they should be replaced by men.
No matter how you use it, let's use it for a while and then see.
After thinking for a while, Xu Chuan decided to get a private email address, phone number, etc. in the future.
Having an assistant is a good thing, but sometimes it is not very convenient in some aspects, especially in some aspects of personal communication.
For some projects or public matters, it is okay for an assistant to handle the preliminary processing.
But when it comes to some personal matters, it would be better for him to do it in person.
Thinking of this, Xu Chuan suddenly remembered another thing.
When he was in Beijing before, he accidentally met Lu Tianrui, an old friend from Xingcheng No. 1 Middle School, at Peking University. He agreed to send him some previous study books when he came back, but he forgot about it when he got busy later.
Fortunately, two new assistants have been recruited, and they can go to the villa to get all the books he had at Princeton.
On the one hand, I organized it, copied some of the books and sent them to Lu Tianrui.
On the other hand, they can be used as learning materials for novice students according to 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 out of scope can help your brain think.
.......
After arranging the work, Xu Chuan checked the homework of the two students and then set off for the Sichuan-Hai Materials Research Institute.
Applying the strong diamagnetic mechanism of KL-66 material to other superconducting materials requires his perfect mathematical methods, but it also requires the computational mathematical model in the Chuanhai Institute of Materials.
Besides, he hasn't been to the institute for a while.
Although someone is managing it for him, as the boss, he still needs to know about the work and progress of the institute.
Arriving all the way to the research institute at the foot of Purple Mountain, Xu Chuan successfully contacted Fan Pengyue in advance.
At this moment, Master Xiong is busy in the laboratory.
Seeing this scene, Xu Chuan became a little curious and asked with a smile: "Why did you suddenly go to the laboratory in person?"
Although this master Xiong himself came from the laboratory and did many experiments with Chen Zhengping, since he took charge of the Sichuan-Hai Institute of Materials Research, he has rarely had the opportunity to go to the laboratory and be an experimental ape himself.
"Graphene!" Wearing a white coat, Fan Pengyue replied excitedly: "We have found a way to synthesize high-quality graphene in batches! We are doing the final experiments. If feasible, this will be the biggest change in the materials world!"
Hearing this, Xu Chuan was stunned for a moment, walked forward quickly, and asked: "When did it happen? Why didn't I listen to your report?"
"Wait a moment, I'll finish this step." Fan Pengyue stared at the device and said without looking back.
Hearing this, Xu Chuan waited patiently.
If high-quality graphene materials can be synthesized in batches and achieved industrial production, it will be one of the biggest changes in the materials industry, as the master Xiong said.
That's right, it's one of them, not the only one.
In fact, compared to other researchers or scholars in the field of materials, his attitude towards graphene is not so enthusiastic.
Although he is also very optimistic about this new material and believes that it has huge potential in the future, he has even used graphene when studying high-temperature copper-carbon-silver composite superconducting materials in the past.
But compared to others, he is still calmer.
Graphene has always been hailed as the "King of New Materials" by the materials community.
Extremely high strength, extremely high electrical conductivity, extremely high thermal conductivity, ultra-thin, high transparency, high flexibility, high chemical stability, magnetic...and other excellent physical properties in all aspects
, giving it wide adaptability.
From basic raw materials to new nanomaterials, high-performance electronic devices, energy storage and conversion, medical biology and other cutting-edge fields, graphene is suitable for all.
But it is not without its shortcomings.
For example, it is often said that high-quality production is difficult, it is easy to oxidize in the air, and the use environment requires special packaging, etc.
In addition to these general shortcomings, the biggest problem with graphene is not actually here.
The biggest problem with graphene is that its paper performance is extremely good, but its application performance is actually very average.
Yes, extremely high strength, extremely high electrical conductivity, extremely high thermal conductivity... are all the advantages of graphene, but no one has ever told the world that these advantages almost only exist in experiments.
chamber or microscopic level.
Those extremely excellent properties either only exist on PPT paper, or only exist in the laboratory, or they can only be possessed by very perfect graphene.
For example, everyone must have heard of the excellent mechanical properties of graphene, which surpass steel.
But what no one tells you is that the purity of graphene is extremely high and requires a special assembly process.
In conventional manufacturing, the mechanical properties of stacked graphene become almost the same as those of graphite. In this regard, carbon fiber materials are currently stronger and can even be said to kill graphene.
There is no way, the current graphene simply cannot achieve the mechanical properties of PPT.
Or let’s talk about batteries. The capacity of graphene batteries has been very loud 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 losing stability during electrochemical reactions, which will lead to problems such as a decrease in the capacity of the electrode material and a 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, we still need to see development in the future.
However, for Xu Chuan, if Chuanhai Materials Laboratory can find a way to mass-produce high-quality graphene, it would be quite impressive.
At least, there is currently no way to industrially produce graphene in the world, and the gap is huge.
This chapter is not over yet, please click on the next page to continue reading! If it can be marketed in batches, graphene can bring him at least several billion meters of gold market every year.
The global production of graphene in 2019 was only 1,200 tons in all countries combined.
Compared with the global market demand for graphene, this number is not even a drop in the bucket.
Moreover, he can also seize the opportunity in the research of graphene.
After all, when the cost comes down, people will naturally be willing to continue investing in it.
.......
After waiting for a short while, Fan Pengyue completed the steps in his hands and handed over the subsequent experiments to his assistant.
"What happened? Why did you suddenly break through?" Xu Chuan asked curiously as he looked at Master Xiong who took off his experimental gloves and came over.
Fan Pengyue smiled and replied mysteriously: "I have to thank one person for this!"
"who?"
"That little girl of yours."
"Liu Jiaxin?" Xu Chuan was stunned for a moment and asked with some surprise: "How does the breakthrough of graphene have anything to do with her?"
Fan Pengyue said with a smile: "After she came back last year, didn't you ask her to help build a safety protection platform for the Sichuan-Hai Materials Institute? Because she needs to communicate with the institute, she often comes here to discuss it."
"In the second half of this year, when studying the rapid synthesis of graphene circuit discovered in 2019, the institute encountered some difficulties. She helped to re-optimize and design the material model for this aspect."
"Then through the model, we have recently found a feasible path, which has been verified through supercomputing and computing models, and is feasible for production."
"So currently the entire graphene department is working overtime to do experiments, and I don't have the time to integrate the materials and report to you."
"But if you don't come, I should contact you in the next two days."
Xu Chuan suddenly nodded and said: "So that's it."
Fan Pengyue asked curiously: "Speaking of which, what is your relationship with that junior girl? Can you ask her to do a favor?"
"What can I help you with?" Xu Chuan asked curiously.
"Ask her to help optimize the material calculation model." Fan Pengyue said: "You know, as more and more mechanical data of materials are added, the volume of the model you made before will become larger and larger."
"In fact, it is already quite large now, and each calculation requires a huge amount of computing power. If it were not for the huge computing power provided by the newly built supercomputer at NTU, the institute would not be able to carry it.
of."
"The computing power of NTU's supercomputer 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'm afraid we will have to build our own supercomputer."
"Although the institute has been 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 junior high school girl is really good at mathematical modeling. I feel like you can't even compare to her in this aspect."
"The graphene computing simulation module we are using now is the architecture she helped redesign. Its computing performance is about 170% higher than the one we wrote before."
"That's why I wanted to ask her to help re-optimize the overall structure."
Xu Chuan nodded and said: "I will ask this later. It is indeed time to optimize the architecture."
After a pause, he continued: "But now let's talk about graphene. How do you mass produce it?"
Compared with optimizing the computational material model, Xu Chuan would be more curious about how high-quality graphene is mass-produced.
You must know that this thing had not been fully industrialized before he was reborn and came back. The difficulty is obvious, it is quite high.
