Ahem –

Early the next morning, Pang Xuelin was kicked out of bed by two daughters before waking up.

Then Yao Bingxia and Qi Xin gave Pang Xuelin a big look, wrapped up their clothes and quietly went back to their respective rooms.

Fortunately, the three of them were arranged to live in the bedroom on the third floor, which was more private, so they didn't find out about last night's absurdity by Mei Yuqing.

Pang Xuelin was in a very comfortable mood, and he couldn't help grinning when he ate breakfast.

Mother Mei Yuqing couldn't help but say: "Xiaolin, what's so happy, silly and happy?" ”

As soon as these words came out, the two murderous eyes at the table instantly focused on Pang Xuelin.

Pang Xuelin hurriedly said: "It's nothing, I just received news from the Carbon Nano Center, there is a project that has been studied for a year, and a breakthrough has just been made, I will go over later." ”

Mei Yuqing said: "You have been lying in bed for so long, you just came out of the hospital, and you are going to start busy again?" ”

Pang Xuelin said: "Mom, don't worry, I'm in good health, besides, didn't the country arrange a medical team for me?" Oh, by the way, Mom, I want to move back to the Jiangbin villa, otherwise it will be inconvenient to go to the Qiantang laboratory construction site......"

Mei Yuqing said: "Hmph, stinky boy, are you tired of living with us?" ”

At this time, Yao Bingxia, who was sitting opposite Pang Xuelin and was drinking porridge, said: "Aunt Mei, I'll accompany you here, let Brother Xiaolin go to Jiangbin to live alone." ”

Qi Xin also followed the mending knife and said: "Yes, Aunt Mei, Xiao Xia and I are here to accompany you......"

As she spoke, the two girls winked at Pang Xuelin proudly.

Pang Xuelin couldn't help but feel a little helpless, these two girls were obviously not their opponents last night, but now they are pretending to be tigers, taking advantage of their mother's momentum to squeeze themselves, but there is nothing they can do about them.

Mei Yuqing said with a smile: "This is not necessary, Xiao Xia Xiaoqi, you should also follow Xuelin to live on the riverside." This kid doesn't know how to take care of himself when he works, so you stay with him and help me supervise him. Usually whether you eat or sleep, you must be on time. ”

"Huh?"

Qi Xin and Yao Bingxia both had a hint of blush on their faces.

"What's wrong?"

Mei Yuqing said a little strangely.

"Oh, nothing, nothing......"

Yao Bingxia hurriedly shook his head and said.

Qi Xin also shook his head.

Pang Xuelin drank porridge while trying to hold back his laughter.

Soon, his face changed, for he felt his left and right insteps being stepped on several times.

Pang Xuelin could only grin his teeth and endure the destruction of these two girls.

After eating breakfast, Pang Xuelin put down the dishes and chopsticks and said, "Mom, Zhou Chen and Zuo Yiqiu are already waiting outside, I'll go first." ”

Pang Xuelin was in a hurry to rush to the Carbon Nano Research Center on the Yuquan Road Campus of Jiangda University, Qi Xin and Yao Bingxia naturally wouldn't follow, they would have to pack up their things and go to Binjiang later.

Coming out of the villa, Pang Xuelin saw Zhou Chen and Zuo Yiqiu waiting at the door, there were three Hongqi cars parked on the side of the road, two of which were Hongqi N501, and the one in the middle turned out to be Hongqi L5, but both the appearance and interior have changed from the original L5, giving people a younger feeling.

Pang Xuelin was curious: "Is this a change of car for me?" ”

Zhou Chen said with a smile: "Professor Pang, these three cars are specially built for you by Hongqi Company, using the all-electric power of the Golden Dragon battery, with a range of more than 5,000 kilometers, and this should be the only three electric vehicles in the world that use the Golden Dragon battery." ”

Pang Xuelin couldn't help crying and laughing, he didn't expect that Hongqi Company would do this.

However, it is understandable to think about it, since the official launch of King Long battery, in just one month, domestic car sales have dropped by ten percentage points, and electric vehicle brands such as Tesla have been cut in half.

Many people who are ready to buy a car are waiting to see when the King Long battery car appears, and they can start it as soon as possible.

Therefore, major car companies are trying their best to establish a good relationship with King Long Group, hoping to become one of the first manufacturers to launch King Long battery cars.

At present, Hongqi Automobile has been designated as the first batch of King Long battery car manufacturers, and will be built into a brand of official cars and high-end luxury electric vehicles in the future.

As for the other manufacturers that are also shortlisted, they are mainly domestic brands, such as Geely, Roewe, BYD, NIO, etc.

Tesla, Volkswagen, Toyota, Mercedes-Benz, BMW and other brands, due to export controls, can only wait for China to complete negotiations with other countries and reach an export agreement on King Long batteries before they can enter the second batch of authorized lists.

From this point of view, it doesn't seem like a big deal for Hongqi to order a car specifically for him.

After getting into the car, the engine started silently, and soon, the Hongqi L5, escorted by two other Hongqi N501s, went out of the villa area.

Then outside the villa area, two more police cars followed.

Pang Xuelin was a little helpless, and his security level seemed to have been improved again.

However, this is also understandable, the strategic significance of the Golden Dragon battery is too great, and he has just woken up from a coma, and the country's attention to his personal safety can be imagined.

When I arrived at the Carbon Nano Research Center, it was already 10 a.m.

Xu Xincheng, President of Jiang University, Xu Xingguo, Dean of the School of Materials Engineering, Li Changqing, Deputy Director of the Carbon Nano Research Center, and Wan Yi, Deputy Leader of the High-performance Carbon Nanotube Fiber Materials (Flying Edge Materials) Project Team, have been waiting for a long time.

"Academician Pang, I heard Lao Xu say that your high-performance carbon nanotube fiber material project team is ready to officially start the feeding experiment today, don't mind if I come over and have a look."

Xu Xincheng said with a smile.

For Pang Xuelin, Xu Xincheng is now full of confidence, and he can make such a big move in the lithium-air battery project that no one is optimistic about before, so what about the high-performance carbon nanotube fiber material project that has been prepared for a year?

You must know that Jiang Da has also invested a lot of money in this project.

If he can really come up with a high-performance carbon nanotube fiber in theory, even a layman will understand what this means.

This will be the strongest supermaterial in the world.

This kind of carbon nanotube, which is hundreds of times stronger than steel, has excellent mechanical and thermal properties, and has a wide range of application prospects in aerospace and other fields.

What's more, according to Wanyi, what they want to do is to do high-density macro preparation.

In other words, it has the ability to quasi-industrial mass production.

Even if the production is not high, it can play a crucial role in some key areas, such as hypersonic vehicles, rockets, heavy satellites, space stations, and manned lunar landings.

And to a certain extent, if this material is successful again, then in the field of carbon nanomaterials, Jiang University has another discipline that sits in the first position in the world.

You must know that in the past two years, with Pang Xuelin's great success in Jiang University, a large number of talents have been cultivated and attracted to join.

At present, Jiang University has gradually stood out from the competition with the top universities in the south, such as Fudan, Shanghai Jiaotong, Nanjing University, and University of Science and Technology of China.

Now in China, it has the reputation of North Qing North and Nanjiang University.

As long as Pang Xuelin stays at Jiang University, this momentum continues, and Xu Xincheng is fully confident that Jiang University will develop Jiang University into China's version of MIT.

Pang Xuelin naturally didn't know what Xu Xincheng was thinking, and smiled when he heard this: "Of course I don't mind." ”

Then, he exchanged a few words with Xu Xingguo, Li Changqing, and Wan Yi, and then went directly to the experimental center where the flying blade material project team was located, which was a five-story building covering an area of 500 square meters.

This experimental center is located in the west of the School of Materials Engineering, which used to be the location of the Institute of Nanomaterials of the School of Materials Engineering.

Entering the experimental hall, the first thing that catches everyone's eyes is a huge annular structure reaction black box, the diameter of this ring structure is more than 20 meters, the diameter of the reaction black box is also more than one meter, and the discharge port is a thin mouth only the size of a hair.

"Academician Pang, is this the discharge port of the flying blade material you said?"

Pang Xuelin nodded with a smile and said: "The diameter of the meter-level length single-walled carbon nanotubes is only about 10 nanometers, and the single-walled carbon nanotube fibers we are going to prepare today will be composed of five hundred meter-level length single-walled carbon nanotubes, and the diameter is expected to reach 4-5 microns, which is equivalent to a human hair." If all goes well, we will also prepare kilometer-long flying blade materials in the future. It is even possible to weave carbon nanotubes to create carbon nanotube structures with super toughness and stiffness. ”

Xu Xincheng smiled: "Okay, then we won't waste time, why don't we start now?" ”

"Good!"

Pang Xuelin nodded and led everyone to the control center.

The control center was already crowded with members of the project team, Pang Xuelin shook hands with these people one by one, and after saying hard work, it was announced that the first preparation of the flying blade material project had officially begun.

With the start of the machine, even in the hall of the control center, a buzzing roar can be felt.

However, although the reaction black box is huge, it is only in the experimental stage now, and considering various factors, the reaction speed is controlled quite slowly.

According to the calculation of the project team, only about one centimeter of fiber can be grown per hour, and it will take at least four to five days to complete the preparation of meter-sized carbon nanotube fibers.

Pang Xuelin: What they have to do today is just an experimental run, and they only need to prepare a sample of some centimeter-level length, and after testing, it is determined that there is no problem, and then the reaction black box will enter the large-scale full-power preparation stage.

It was announced that the preparation had started just in time for lunch, but no one wanted to leave the control center, and lunch was brought by the canteen staff and dealt with casually.

At two o'clock in the afternoon, the first 2.8 cm long carbon nanofiber sample rolled off the production line, and then the project team members directly sent it to the electron microscopy center for testing.

At 5 p.m., the first scanning electron microscope photos with a resolution of 3.5 nanometers and the analysis report of the sample appeared in front of Pang Xuelin.

Wan Yi, Li Changqing, Xu Xingguo, and Xu Xincheng also came over one by one.

What appeared in front of Pang Xuelin and them was a collection of tubes arranged as a whole.

[Fig. 1 shows the neat arrangement of the tubes under the graphite substrate, showing that the growth direction of the single-walled carbon nanotubes is unidirectional, which is consistent with the expected results.] Figure 2 shows the electron diffraction spectrum of a single-walled carbon nanotube, in which the 000L-type diffraction point is strong, because the planar family on the two walls parallel to the incident electron beam in positive space satisfies the band axis law. Conversely, the HK0 type point such as the 1010 type point in the figure is much weaker. In addition, the spots except for the 000L type have obvious stripes, the direction is perpendicular to the tube axis, and the intensity decreases outward from the circumference of HK0. Moreover, these spots are arranged in a hexagonal shape, which can be attributed to the planar hexagonal structure of the carbon ring. A closer look shows that there are also symmetrical satellite points on either side of these points, which are located on a circle with the sum of the length of the inverted vector. The spiral structure of such satellite points in real space and the resulting top-bottom effect ......】

[The projections on the left and right sides of Figure 3 are not completely symmetrical, indicating that the spacing between the layers of some layers is not the same.] The asymmetry of the projection surface reflects that the body of the carbon nanotube is not a standard round tube structure, and its cross-section may be a polygonal sectional structure. The asymmetry in Figure 3 can be explained in Figure 4B. The left d d and right h values are not the same. When Figure 4 is rotated by 90 degrees, symmetrical stripes will appear on the left and right sides.

……

After reading the scanning electron microscope report, Pang Xuelin handed it to Wanyi next to him, and after Wanyi finished reading it, he handed it to Li Changqing.

Then this report was passed through one by one among the members of the project team, and finally passed to Xu Xincheng.

"Academician Pang, how is it?"

Xu Xincheng is not an expert in the field of carbon nanotubes, so he can only look at a rough idea, but judging from the expressions on everyone's faces, he can feel that the performance of this sample is very good.

Pang Xuelin smiled: "If we usually prepare large amounts of large-size single-walled carbon nanotubes, their orientations are generally chaotic, and these single-walled carbon nanotubes with consistent orientation have already shown that our experiment is half successful." The next thing to look at is the performance of this equipment when it is running at full power, if it is running at full power, we can prepare more than 10 centimeters of carbon nanotube fibers per hour, except for four hours of shutdown and maintenance every day, and the rest of the time will be kept running, and it can reach one meter in five days. Let's see how long the single-walled carbon nanotubes can be prepared in the end. ”。

Wan Yi on the side also nodded and smiled: "Anyway, I am very confident, as long as this equipment can continue to operate stably for more than a month, it means that Professor Pang's overall plan is completely feasible, and then we can upgrade and transform on the basis of this device to speed up the synthesis of single-walled carbon nanotube fibers." ”

Xu Xincheng said with a satisfied smile on his face: "Professor Pang, Professor Wan, then I will work hard for you next." ”
