Scholar’s Advanced Technological System

It was obviously not just Professor Stanley who was shocked.

When Director Li returned to Shanghai with the sample and helped Lu Zhou take the fast track to register the ownership of the patent, the trustee then sent it to the Hangke Group.

Almost the next morning, the sample was delivered to the Hangke Group. Academician Yuan Huanmin rushed to the Bureau of Science and Industry, and found Director Li's office non-stop.

"That sf-1 super fiber! Which unit made it out ?!"

Staring blankly at Academician Yuan who was standing at the door, Director Li's face was filled with surprise that was not inferior to him.

If he remembered correctly.

That bag of samples should have been delivered to the old academician yesterday afternoon ...

"Cough, calm down with drool first," said Chief Li, looking at the secretary who was standing in the office with the same expression, and said, "Little Li, go and give Yuan Yuan a cup of tea. "

"Okay, okay."

Mumu nodded, and the secretary named Xiao Li quickly walked to the side of the cupboard with the electric kettle, and took two cups of tea on the coffee table in the office before long.

Standing up from the desk, Director Li took Academician Yuan to sit down on the sofa in front of the coffee table and explained.

"Some time ago you asked me to ask Academician Lu if he could get this thing out? I went to Jinling this time and asked casually, and then he gave me this thing."

It was okay to hear the previous part, but when I heard the latter part, Academician Yuan Huanmin, who was drinking tea, almost did not spit out the water he just drank.

"Then he gave you this thing?" Forcing a sip of tea, Academician Yuan's old face turned red, and his excited tone was full of aggressiveness and incredible, "What the hell?"

Looking at his aggressive expression, Director Li was probably able to appreciate his mood, so he couldn't help smiling a bit.

"I know you're surprised, in fact I'm even more surprised than you. From the time I asked him if he was sure, and he threw the finished product in front of me, there were still five minutes before and after, you can imagine my face His expression ... probably more exaggerated than you are now. "

Looking at Director Li, who was sitting opposite him, Academician Yuan nodded his head first, then shook his head again.

If this is the case, he can really imagine the surprise in Director Li's mind at the time, but what he couldn't imagine is how exactly Lu Zhou got this thing out in five minutes? !

"But how is he--"

"I know what you want to ask, but I don't know, I just heard that it is the method of computational materials science to build a model, and then the laboratory quickly verifies what ... Don't worry about it first, you tell me first, this thing Is it easy to use? "

"Just easy to use?" Faced with that earnest look, Academician Yuan shook his head with a smile and sighed softly, "Have you ever seen a nylon rope?"

"Of course I have seen this, eh?"

"Change the polyamide fiber twisted into a nylon rope to the super fiber you gave me yesterday," looking at Director Li, Academician Yuan said in a serious tone, "the tensile strength can be turned up at least a thousand times."

"A thousand times ?!"

Frightened by this number, Director Li's expression could not help but move slightly, and could not help asking.

"Yes, is there such an exaggeration?"

Looking at the expression on the face of Director Li, Academician Yuan Huanmin shook his head.

"No exaggeration at all."

The Young's modulus of the nylon rope is about 1.4 gpa, and the unit of the Young's modulus of this sf-1 super fiber has changed from gpa to tpa, even if a series of factors such as process may be taken into consideration, this This statement is not exaggerated at all.

"It's no exaggeration to say that using this thing to make cloth or clothes is a bulletproof jacket without ceramic lining. Using this thing to make a rope is that the aircraft carrier blocks the cable-level tensile force. We also have other physical properties No test, but in terms of tensile strength, I can't imagine a material stronger than it! "

"Is it so awesome ..."

"It's more than that," Academician Yuan sighed. "It's only our imagination that limits its use, maybe ..."

"not sure?"

After pondering for a while in the imagination, it seemed that he felt that his thoughts were too exaggerated, and Academician Yuan quickly shook his head and denied his thoughts.

"No, that ... is still a bit exaggerated."

Tickled by Guan Zi, who was sold by this guy, Director Li was anxious and asked.

"What an exaggeration are you talking about?"

Speaking in half, is this a human thing?

It seemed to feel that his approach was a bit immoral. Academician Yuan Huanmin hesitated a moment and finally said it.

"I want to say, maybe even a space elevator ..."

"It is also possible!"

......

As the saying goes, the more you know, the less your imagination will be.

After all, scholars like Dyson are a minority, and most people gradually lose their seemingly unrealistic illusions about science as their knowledge reserves increase.

Hearing the word "space elevator" from the mouth of Yuan Huanmin, an old academician who has studied in the aerospace field for decades, is quite a rare thing for Director Li.

However, compared to the space station at Lagrange and the scientific station on Mars, this stuff is still a bit beyond his imagination.

No matter how surprised he is now.

When Academician Yuan found his office, the entire material science community was shaken by a thesis!

Mizuki Forum.

"Have you read that paper? That's the one that Lu Shen uploaded to arxiv recently!"

"Don't pay attention. We are engaged in materials engineering. The research direction is not mathematics and physics. Pay attention to what his thesis is doing."

"He sent a paper on material direction!"

"Crouch ?! Really? How long hasn't he studied materials? Didn't he study physics later?"

"He resigned from the post of chairman of imcrc some time ago ... don't talk about it, please go and have a look. When our professor just saw the paper, his jaw was surprised!"

The title of the thesis is short, and can be read in as little as two seconds.

However, the amount of information in it is not ordinary!

Since the birth of the discipline of computational materials science, theoretical calculations of complex systems have faced two major challenges. One is how to translate the accurate theoretical treatment at the micro level into a direct description of mesoscopic and macro-level phenomena, and the other is how to further improve the accuracy of the density functional methods that are the basis of existing large-scale calculations.

The limitations of implicit functional density in describing Van der Waals forces, metal bonds, and other issues have always been a major headache for researchers in the field of computational materials.

However, this problem is actually solved by a paper on arxiv so easily?

Everyone was shocked by the unexpected news.

And not only that!

Even more surprising is that the name hanging on this paper is actually Lu Zhou!

How long has he not been engaged in the research of materials science since the last achievement, many people have not remembered it well.

No one expected that he resigned from the board of directors of imcrc, in order to pave the way for the return to the material science community.

What is even more unexpected is that as soon as he came back, he did such a big thing ...

It's so scary!
