Scholar’s Advanced Technological System

Nanjing Institute of Advanced Studies, Material Science Laboratory.

Standing next to an optical microscope, Lu Zhou slightly 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 toward 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, the longer one can reach 2mm, but the number can be counted on one’s fingers.

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…

Touch the chin meditation for a while, 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 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.

Expression Intricately staring at the picks on the microscope, Lu Zhou still asks some unwillingness: “Is there a little idea?”

“That’s not the case. There is still a little bit of thinking.” A report was pulled from the side of the experimental table. Yang Xu handed it to Lu Zhou’s hand. “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 terms of this property, this 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 said: “… then do it according to the ideas you said. If the funds are not enough, just tell me.”

“You can rest assured that I will not be polite with you when I am short of funds,” Yang Xu laughed, paused continued. “Yes, I have to ask you something, now the problem of laboratory preparation has been solved. … need to register a patent?”

Lu Zhou thought for a while and said, “First register the carbon nanotube sample, prepare the catalyst, and so on.”

Yang Xu: “What about thesis?”

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

Keeping the synthesis process secret, simply using a sample with a nitrogen-containing group as a meaningful carbon nanotube submission will work well 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 world. It’s the same in any field of academia. The higher the heat of a problem, the more research institutions are interested and the faster the results.

Just relying on a research institute to build a car behind closed doors. If you don’t exchange ideas with other Scholars or research teams, you can’t see the results for a decade or so.

“That’s what you said,” Yang Xu nodded, 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, I was embarrassed to smile, seriously thinking for a while, and 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 the 1 number. If you later research a newer type of similar material, you can just analogize it according to the 1234 rule.

Although he also considered what is similar to the “super-stranded carbon nanotubes” or “carbon nanotubes that are 100 times stronger than steel”, the material is more appropriate, but because it is too much space to write, so This thought was dispelled.

Satisfied with the ability to name himself, Lu Zhou turned his attention to Yang Xu, originally intended to ask his opinion, and he saw that he had not responded for a long time, so 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 Lu Zhou’s mobile phone.

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

“Hey?”

“it’s me.”

Listening to Li’s tone is not quite right, Lu Zhou has no chills and asks straight into the subject.

“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.

For the most recent particle, the GOES-17 satellite in the United States 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 blind, 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.

At first, it was a problem with heat dissipation. Lu Zhou immediately asked: “Can’t it be solved 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 was on the loop heat pipe, Lu Zhou suddenly stunned and immediately realized that the problem is 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 this fuck and the removal of the entire core compartment shell to the furnace?
