Scholar’s Advanced Technological System

Jinling Institute of Advanced Studies, Materials Laboratory.

Standing next to an optical microscope, the ark turned slightly to look at the carbon nanotube fibers on the glass.

About four or five minutes later, Ark's eyes left his glasses and looked at Yang Xu standing next to him.

“Can't you do it longer? ”

Yang Xu shook his head.

“That's the best we can do. ”

According to the data observed under the microscope, the shortest samples were only 5-10 μm, and the longer ones were up to 2 mm, but the number was extremely high.

Desperately, even carbon nanotube samples grown to 2mm. The sample lying on this glass is like a pile of mustache, or the kind that shaves unevenly, compared to the one on that fabric that is as smooth and shiny as hair...

Touched his chin and pondered for a while, the ark said.

“… what about the directional growth technology used on SG-1 superconducting materials? Have you tried? ”

“I've tried everything you can think of." Yang Xu shook his head. "This high-tensile strength carbon nanotube has a much smaller pore size than the pore size of the SG-1 material. It's difficult to synthesize it by directional growth... and you can take 10,000 steps back. Even if you can do it this way, it's hard to accept it in terms of cost? ”

If the superconducting material is okay, it is itself used in high-tech fields, and it is acceptable if not expensive. But if it's just a tensile material that costs so much blood, it's a little unnecessary.

The divine color stared at the microscope diaphragm, and the ark was still somewhat immortal and asked: “No thought at all? ”

“That's not true, there is still a bit of thinking,” from the side of the experimental table turned out a report, Yang Xu passed into the hands of the ark, “According to the information feedback from several sets of experimental data, improving the type of catalyst can effectively improve the proportion of long-carbon nanotube molecules in the product. In terms of this property, this surface modifies carbon nanotube molecules with nitrogen groups, similar to some samples I've done before. ”

“So we just need to constantly improve the catalyst so that it stays active as the carbon nanotube grows at high temperatures, theoretically increasing its length. ”

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

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

After listening to Yang Xu, Ark nodded and said: "... then do as you say, if you don't have enough money, just tell me. ”

“You can rest assured, I will definitely not be polite with you when there is a lack of funds," Yang Xu smiled and continued, “By the way, I have to ask you something, now that the lab preparation problem has been solved... do you need to register a patent? ”

The ark thought for a while and said, "Register a sample of carbon nanotubes, make a catalyst, and so on. ”

Yang Xu: “What about the paper? ”

Ark: “When the patent is registered, you can consider organizing the content other than the preparation process and putting it into a zone. ”

Confidential to the synthesis process, simply posting a sample with nitrogen-containing groups on the surface as an interesting carbon nanotube can also work in the material sciences.

It would also be beneficial for him to attract more research institutions.

This is true not only of the material academia, but of any field of academia, where the higher the heat of a problem, the more interested research institutions are, the faster the results are produced.

Without an exchange of opinions with other scholars or research teams, a problem that comes down for more than a decade will not necessarily see results.

“Then do as you say,” Yang Xu nodded and continued, “... by the way, what name shall we give it? ”

I didn't really think about it. Yang Xu subconsciously asked.

However, he regretted it as soon as it was said.

Just ask, even if you want to regret it again, it's too late.

I was just embarrassed to see the ark and laughed. I thought about it for a while and said.

“Just call it N-1. ”

The naming principle is nothing special, purely considering that the nitrogen-containing modifying group on the surface of this carbon nanotube is too distinctive for other carbon nanotube materials, so simply use the letter N to name the series of these materials.

As for N-1, naturally because it is No. 1, if an updated similar material is developed at a later stage, it is sufficient to follow the 1234 pattern directly to the rear analogy.

Although he had also considered names similar to “super tensile carbon nanotubes” or “100 times more tensile carbon nanotubes than steel” describing material performance, the idea was dispelled by the fact that it took too much space to write.

He was quite satisfied with his ability to name himself, and Ark Boat threw his gaze at Yang Xu. He was going to ask his opinion, but he didn't respond for half a day, so he hesitated to ask.

“… what is it? ”

“Nothing...” Yang Xu smiled embarrassingly and politely, “I just thought it was quite your style. ”

Ark: “…? ”

What's that supposed to mean?

Look down on the taste of my name?

At this point, a telephone call suddenly reached the phone of the ark.

He took out his phone and looked at it. He saw that it was Director Li. Ark Zhou and Yang Xu said hello. Then he pressed the connection button and walked to the hallway outside the lab.

“Hello?”

“It's me.”

If you listen to Director Li's tone is not right, the ark will not be cold, and ask straight to the point.

“What's going on? ”

Indeed, Director Li's next sentence confirms his bad hunch.

“… something went wrong on the Aeronautics Group's side, the heat dissipation system in the core compartment did not have enough heat dissipation power," he paused for about two or three seconds and said heavily, "the launch plan may have to be postponed. ”

Heat dissipation is a serious problem for spacecraft and is difficult to detect at the design stage. While current technology is already capable of simulating total heat production and heat dissipation, this simulation may eventually deviate from the actual situation for a variety of reasons.

To name just a few recent particles, the GOES-17 satellite in the United States was exposed to solar radiation and overheating due to design flaws in its cooling system, preventing it from gaining effective and timely access to infrared cloud maps, and at night, like blind people, hundreds of millions of dollars were invested in water drifting.

In a sense, we are already quite fortunate to be able to spot problems on the ground. After all, it's almost impossible to think about overhauling a spacecraft after it's been in the sky.

As soon as it heard there was a heat dissipation problem, the ark immediately asked: "Can't it be solved by adding a heat dissipation plate? ”

Director Li said in a heavy tone: "... the problem is not the heat sink, it is said to be the loop heat pipe. ”

As soon as I heard the problem was on the loop heat pipe, the heart of the ark snapped and immediately realized that the problem was probably not simple.

“… you mean the whole loop heat pipe has to be redesigned? ”

The sound coming from the other end of the phone brought a little bitterness.

“I'm afraid so. ”

Ark: “…”

Mother...

Redo the loop heat pipe!

What difference does this Nima make to removing the shell of the entire core compartment and sending it back to the furnace?
