On the other side, looking at the engineers who were excited and cheering and hugging each other, looking at the temperature-time function curve that had no egg regularity, Yang Xu's mouth slowly opened and closed again.

Is this what a Fields Medal winner is capable of?

No wonder the Nobel Prize committee was impressed by his abilities......

It's no wonder that the entire computational materials science community is crazy about his theory......

Once upon a time, Yang Xu believed that he was very close to the Nobel Prize, especially after winning the "Citation Laureate Award", which is known as the vane of the Nobel Prize, with lithium-sulfur battery cathode materials and SG-1 superconducting materials, he firmly believed in this.

The reason why the Nobel Prize Committee did not consider him was mainly because the name of the collaborator of the paper was too dazzling, and sooner or later he would be able to come up with his own results and complete the qualitative change through the accumulation of quantity!

Now, however, he felt a deep sense of powerlessness.

Looking at himself reflected in the floor-to-ceiling window, Yang Xu shook his head with a headache with a smile.

Those who can win the Nobel Prize are monsters......

Sure enough, I'm still far behind......

At that moment, his distant thoughts were interrupted.

Seeing walking through the crowd, Academician Yuan grabbed his shoulder and asked eagerly.

"What about Professor Lu? Where is he now? ”

Looking at Academician Yuan with an eager face, Yang Xu was slightly stunned and spoke.

Professor Lu ...... Already went back. ”

Director Zhang, who was following behind Academician Yuan, hurriedly asked.

"Where have you been?"

"Of course, it's back to the hotel......"

Otherwise, where else can I go, is it difficult to go back to Jinling?

Yang Xu looked at the relieved two with a strange expression, not quite understanding what they were worried about.

After settling down, Academician Yuan looked at the assistant who was following him and spoke.

"Immediately go get the car ready, we'll go to the hotel now."

Hearing that Academician Yuan was planning to leave, Director Zhang hurriedly asked, "What about the experiment?" ”

Academician Yuan pondered for a while and continued.

"Let's finish it for twenty-four hours."

Although he already knew it in his heart, the experiments had already begun, and the process was still complete.

After explaining the next experimental arrangements, Academician Yuan did not stay, and walked out of the factory with Vice President Zheng, who followed closely behind.

……

Mathematics is the language of the Creator.

And the question of mathematics is a riddle left by the Creator.

Many things don't necessarily have to be seen with your own eyes, and many times pure numbers are more intuitive than what you see.

As for that seemingly irregular, temperature-time function......

It may seem strange to others to solve it, but for him, it is not even a challenge.

After leaving the Space City, Lu Zhou, who was in a good mood, got on the white Volkswagen that Wang Peng borrowed from the local Guoan and asked him to drive directly back to the hotel.

Noticing through the rearview mirror, the expression on Lu Zhou's face was quite pleasant, and Wang Peng asked with a smile.

"Did anything good happen?"

"Sort of," Lu Zhou said in a relaxed tone, "After solving this matter, the Moon Palace will finally be able to get on the road safely." ”

Wang Peng didn't ask how it was solved, after all, he knew that he wouldn't understand even if he asked.

Glancing out the window, he asked.

"What about Professor Yang?"

Lu Zhou smiled and waved his hand: "Don't wait for him, he doesn't believe me, I have to wait there to see the results, and I will take the car from the Hangke Group back later." ”

Wang Peng: "You made a bet with him again?" ”

Lu Zhou glanced at him unexpectedly.

"How do you know?"

"You can guess it!"

Wang Peng shook his head with a smile, started the car, and after driving on the highway, he followed the navigation and drove in the direction of the hotel......

……

When he arrived at the hotel, Lu Zhou returned to his room and packed his luggage, called his assistant Zhao Huan, and asked her to help book two high-speed rail tickets for himself and Yang Xu for the return trip.

After hanging up the phone, I saw that it was almost dinner time, so I went downstairs to the cafeteria on the first floor.

The elevator door opened, and just when Lu Zhou arrived at the lobby on the first floor, a series of dense footsteps came from the direction of the door.

Lu Zhou raised his eyes and saw Academician Yuan walking in with a large group of people.

Including, Yang Xu, who did not come back with him before, as well as Academician Yang Zhongquan from Shen Ji, and Vice President Zheng, the person in charge of the space station project, are all inside.

Only Director Zhang was not there at that time, so I guess he was still in the laboratory.

Looking at the people who came and smiled, Lu Zhou was about to step forward to say hello to Mr. Yuan, but saw that Academician Yuan had already walked quickly in front of him, and hurriedly said without saying a word.

"What the hell did you get in there?"

Lu Zhou: "It doesn't work to answer me first." ”

"It works!" Academician Yuan nodded vigorously, and said excitedly, "It's not for ordinary droppers!" ”

Lu Zhou smiled and said, "Actually, it's not a mysterious thing, it's just that by plating copper on N-1 carbon nanotubes to improve their affinity at the interface of aluminum-copper alloys, and then cold-welding the material to the contact point between the heating part and the capillary structure of the loop heat pipe, the problem is basically ......solved."

To put it simply, it is equivalent to coating several parts with high heat generation in the core cabin with a layer of "heat dissipation silicone", which increases the heat exchange rate between the heating parts and the capillary structure of the loop heat pipe, so that the heat sink as a "fan" can radiate excess heat more efficiently.

Of course, this is just an inappropriate analogy, after all, there is a big difference between the way a spacecraft dissipates heat and the electronic components dissipate heat.

Academician Yuan was going to ask something, but this time it was Academician Yang Zhongquan who spoke first.

"Your N-1 material is interesting...... Are copper-plated carbon nanotubes? ”

Lu Zhou: "To put it simply. ”

"What about thermal conductivity?"

"About 2000w/(m·k)."

In fact, this number can still be improved, but with the current laboratory preparation method, the length of the N-1 carbon nanotube material produced is quite unstable, the short can reach the μm level, and the long can be mm, which is difficult to control.

However, even so, the thermal conductivity of 2000w/(m·k) is quite terrifying.

After hearing the number 2000, Yang Zhongquan gasped, looked at Lu Zhou with disbelief, and said in a tone full of disbelief.

"Your material is a little scary, 2000w/(m·k)...... That's several times more than pure copper! ”

Among the more common metals, silver has the best thermal conductivity, but it is too expensive and rarely used. Copper has the second thermal conductivity, but it is too heavy, and it is generally made into an aluminum-copper alloy with aluminum, which is a common material for loop heat pipes in spacecraft.

At present, the best high thermal conductivity graphite film, the thickness of about 10-20mm, the in-plane thermal conductivity can only achieve 1400w/(m·k). However, even so, it has made the major mobile phone manufacturers high. It's tidal.

2000w/(m·k) thermal conductive powder ......

Speaking of thermal conductivity alone, Nima is about to catch up with diamonds!

Not to mention electronic equipment manufacturers, even the industry is afraid that they will have to follow Gao Chao......

Lu Zhou didn't know much about what the market of thermal conductive materials was in the industrial world, so when he heard Yang Zhongquan's emotion, he just replied with a smile.

"It's okay, right? It just works anyway. ”

Looking at Lu Zhou a little embarrassed, Yang Zhongquan hesitated for a while, and finally as if he had made up his mind, he reached out and touched the back of his head, and asked with a smile.

"By the way, your N-1 carbon nanotube powder...... How do you sell it? Is it expensive? ”

Lu Zhou glanced at him unexpectedly.

"You're interested, too?"

Yang Zhongquan couldn't help but say: "Nonsense, you don't know what high thermal conductivity materials mean in the industrial field!" Take the linear grating ruler on our recent high-precision industrial machine tools, the thermal expansion problem directly affects the accuracy of the side alignment! In the end, the problem will be presented in the form of errors on the workpiece! ”

Although he doesn't understand the specific production problems very well, seeing the appearance of Academician Yang Zhongquan spitting stars flying sideways, Lu Zhou can probably guess that the heat dissipation function of N-1 carbon nanomaterials in the industrial field is probably not small.

It's amazing.

Originally, he positioned N-1 material as a plastic material with high tensile strength, but he didn't expect that because he could not prepare a complete and long small-aperture carbon nanotube, it finally made it shine in the field of heat dissipation.

Quietly waiting for the old gentleman to finish speaking, Lu Zhou coughed lightly and said.

"Let's talk about the question of whether it's expensive or not, now this material is still in the experimental stage, and if it's not that there is such a big problem with the core cabin, I don't plan to take it out. and other methods of mass production to solve the ...... Let's talk about the price again. ”

Academician Yang Zhongquan hurriedly smiled and said, "Success!" Then I'll wait for your good news! Come on! ”

Originally, I came to repay the favor, but I didn't expect to have this harvest.

Just to hear this good news, he made a special trip from Fengtian to come here without a loss!

There was no chance to speak, and seeing that Academician Yang Zhongquan finally stopped his mouth, Vice President Zheng hurriedly stepped forward and asked, "Professor Lu!" There's something else I need to ask you. You welded all the parts in the core cabin, so what should you do when you have to disassemble it? ”

As soon as he heard this question, Lu Zhou suddenly smiled and asked jokingly.

"You're going to go up and tear it down?"

Zheng Xiangdong was stunned, and he didn't react at first.

It wasn't until he noticed Academician Yuan's disgusted eyes that he realized something, and then he smiled and stopped talking.

Indeed, the spacecraft are sent to the sky, unless they reach the end of their useful life and are actively discarded, who will run up to dismantle the installed parts.

Even if it's an overhaul, it doesn't take such a repair......
