Scholar’s Advanced Technological System

Jinling Institute of Advanced Studies, Materials Science Laboratory.

Standing beside an optical microscope, the boat slowly rotated the fine-focus spiral and observed the carbon nanotube fibers on the slide.

About four or five minutes later, Lu Zhou’s eyes left the eyepiece and looked at Yang Xu standing next to him.

"Can't you do it longer?"

Yang Xu shook his head.

"It can only be done at most."

According to the data observed under the microscope, the shortest sample is only 5-10μm, and the longer one can reach 2mm, but the number is very few.

Desperate is even a sample of carbon nanotubes grown to 2mm. The sample lying on this slide is like a pile of beard, or a jagged one, compared to the one on the piece of cloth that is as smooth and smooth as the hairline. Kind...

I felt meditation for a moment, Lu Zhou said.

"...the directional growth technology used on sg-1 superconducting materials? Have you tried it yet?"

"I have tried all the methods you can think of," Yang Xu shook his head. "The pore size of this high tensile strength carbon nanotube is much smaller than that of the sg-1 material. It is difficult to synthesize by directional growth... ...and retreat 10,000 steps, even if it can be done in this way, it is difficult to accept in terms of cost?"

If it is a superconducting material, it is used in high-end fields. If it is used in a small amount, it is acceptable. But if it is just a kind of tensile material, it will be a little unnecessary.

The look of the complex look at the picks on the microscope, Lu Zhou still asked some unwillingly: "Is there any idea?"

"That's not the case. There is still a little bit of thinking." A report was pulled out from the side of the experimental table. Yang Xu handed it to the hands of Lu Zhou. "Based on the information from several sets of experimental data, the catalyst was improved. The type is that it can effectively improve the proportion of long carbon nanotube molecules in the product. In view of this property, the surface is modified with carbon nanotube molecules containing nitrogen groups, and some samples I have done before are Very similar."

“So we only need to constantly improve the catalyst so that the catalyst remains active during the high temperature growth of the carbon nanotubes, theoretically it can increase its length.”

For the growth of carbon nanotubes, the deactivation of the catalyst during high temperature growth is an irreversible law and one of the main reasons for limiting the length of carbon nanotubes.

Therefore, by improving the catalyst and prolonging its deactivation time, it is indeed a technically feasible and cost-controllable research idea.

After listening to Yang Xu’s words, Lu Zhou nodded and said, “...I will do it according to the ideas you said. If the funds are not enough, just tell me.”

"You can rest assured that when I am short of funds, I will definitely not be polite with you," Yang Xu smiled and paused. "Yes, I have to ask you something, now lab preparation." The problem has been solved... need to register a patent?"

Lu Zhou thought for a while and said: "First register a sample of carbon nanotubes, prepare a catalyst for use, and so on."

Yang Xu: "What about the paper?"

Lu Zhou: "After the patent registration, you can consider sorting out the contents of the preparation process and investing in a district."

Keeping the synthesis process secret, simply using a sample with a nitrogen-containing group on the surface as an interesting carbon nanotube submission is also feasible in the material science community.

If you can attract more research institutions to participate, it is also a good thing for him.

It's not just the material science community, it's the same in any field of academia. The higher the heat of a problem, the more research institutions of interest, the faster the results will be.

Just relying on a research institute to build a car behind closed doors. If you don’t exchange opinions with other scholars or research teams, you may not see the results when you think about it for more than a decade.

"That's what you said," Yang Xu nodded and continued. "...Yes, what is the name we give it?"

Did not think much, Yang Xu subconsciously asked this sentence.

However, when this sentence was just exported, he regretted it.

Just ask and ask, and even if you want to repent, it’s too late.

I saw Lu Zhou embarrassed to smile, seriously thinking for a while, said.

"It's called n-1."

There is nothing special about the naming principle. It is purely considering that the nitrogen-containing modifying group on the surface of the carbon nanotube is too characteristic compared to other carbon nanotube materials, so the letter n is simply used to name the series of materials. It is.

As for n-1, it is natural because it is No. 1. If you later research a newer type of similar material, you can just analogize it according to the law of 1234.

Although he also considered what is similar to the "super-stranded carbon nanotubes" or "carbon nanotubes that are 100 times stronger than steel," which describes the material's performance, but because it is too much space to write, so This thought was dispelled.

He was quite satisfied with his own name. Lu Zhou turned his attention to Yang Xu. He originally intended to ask his opinion. As a result, he saw that he had not responded for a long time, so he hesitated to ask.

"……what happened?"

"Nothing..." Yang Xuyi said with a polite smile. "Just think, it has your style."

Lu Zhou: "...?"

What do you mean?

Sorry for the taste of my name?

At this time, a phone suddenly hit the phone on Lu Zhou.

I took out my mobile phone and glanced at it. I saw that Secretary Li called. Lu Zhou and Yang Xu greeted each other, then they pressed the button and walked to the corridor outside the lab.

"Hey?"

"it's me."

Listening to Director Li’s tone is not quite right, Lu Zhou will not have a cold, asked straight into the topic.

"What happened?"

Sure enough, Secretary Li’s next sentence confirmed his bad premonition.

"... There was something wrong with the Hangke Group. The heat dissipation system of the core cabin was not enough." After a pause of about two or three seconds, Director Li said with a heavy tone. "The launch plan may have been postponed."

For spacecraft, heat dissipation is a serious problem and a problem that is difficult to find during the design phase. Although the current technology has been able to simulate the total heat production and heat dissipation, this simulation may eventually deviate from the actual situation for various reasons.

Taking a recent particle, the US goal-17 satellite is due to design flaws in the cooling system, which makes it vulnerable to solar radiation and overheating, making it impossible to obtain infrared clouds in a timely and efficient manner. Once in the evening, like the scorpion, hundreds of millions of dollars The investment is almost sloppy.

In a sense, it is quite lucky to be able to find problems on the ground. After all, after the spacecraft has been in the sky, it is almost impossible to overhaul.

When I heard that there was a problem with heat dissipation, Lu Zhou immediately asked: "Can't you solve it by installing a heat sink?"

Director Li’s tone is heavy: “...the problem is not on the heat sink, it is said to be in the loop heat pipe.”

When I heard the problem, it was on the loop heat pipe. Lu Zhou’s heart suddenly stunned and immediately realized that the problem was not simple.

"...What do you mean, the entire loop heat pipe has to be redesigned?"

The voice from the other end of the phone brought a bit of bitterness.

"I am afraid this is the case."

Lu Zhou: "..."

Mom, yeah...

Redo the loop heat pipe!

What is the difference between Nima and the removal of the entire core compartment shell to the furnace?
