In the office, Pang Xuelin closed the notebook and bowed his head in contemplation.

Half a month has passed since he returned to the real world, and more than a week has been since the start of school.

The Ponzi Workshop is progressing well.

During this time, in addition to brushing up on quantum computer papers, Pang Xuelin either gave lectures to undergraduates or participated in seminars to explain Ponzi geometry theory to young scholars.

The title of the inheritor of civilization rewarded by the system is very effective, and when taking abstract algebra, those undergraduates obviously feel that Professor Pang's lectures have become more interesting and more in-depth.

Even some people who didn't pay much attention to the lecture in class, when they listened to Pang Xuelin's lecture, they couldn't help but be attracted by Pang Xuelin's lecture process, so they followed his train of thought.

As for those in the seminar, it was even more exaggerated.

Ponzi geometry was developed on the basis of far-abelian geometry, although Pang Xuelin has tried to make the theory as obscure as possible.

But there are always places that require a strong abstract mind to understand.

Some people get stuck in these places when they are self-taught.

However, after Pang Xuelin's explanation, they not only had a feeling of sudden enlightenment, but even their understanding of Ponzi geometry was much deeper than the original.

Liu Tingbo ran over to listen to Pang Xuelin's lecture once, and simply asked the young teachers of the mathematics department of the whole school to come over to listen.

In this regard, Pang Xuelin could only shake his head and express helplessness.

Pang Xuelin was thinking about something, when his mobile phone rang suddenly.

The caller ID is Li Changqing from the School of Materials Engineering.

Pang Xuelin pressed the answer button, and soon, Li Changqing's excited voice came from the other end of the phone: "Professor Pang, we succeeded!" High-purity single-walled carbon nanotubes, we have grown electronic-grade single-walled carbon nanotubes with a purity of 99.99999% according to the method you provided, and the characterization work has been completed. ”

Pang Xuelin frowned slightly, and then recalled that "ten years ago", he seemed to have a cooperative research project with the School of Materials Engineering on high-purity carbon nanotubes.

I didn't expect it to succeed so quickly.

However, Pang Xuelin was not too surprised.

The preparation method given by myself is a classic scheme summarized in the wandering earth world, as long as it can be done according to this method, it will definitely produce results.

Pang Xuelin looked at the time on his wrist and said with a smile: "Professor Changqing, it's almost twelve o'clock now, I'll go to the cafeteria to eat first, and I'll go to you after eating." ”

"Okay, I'll see you in the afternoon!"

"Well, see you that afternoon!"

Pang Xuelin thought about it, got up and took out a material from the bookcase behind him and put it in his briefcase, then picked up his mobile phone, put on a long windbreaker and went out.

Jiangcheng at the end of February is still cold in spring.

Pang Xuelin walked out of the office and saw Qi Xin in the suite outside, sitting there in a daze with his chin down.

"Senior sister, what are you thinking, it's been more than half an hour since you got off work, why haven't you gone to eat yet?"

Pang Xuelin said.

"Ah, I didn't think about anything! Professor Pang, are you done? ”

Qi Xin blinked, since she was transferred to work next to Pang Xuelin, when she was at work or when other people were present, she generally called Pang Xuelin Professor Pang, and only when the two of them were together in private, she would call Pang Xuelin a junior.

For this reason, Pang Xuelin corrected it several times, but she always insisted on doing so, and Pang Xuelin went with her.

Pang Xuelin smiled: "I'm done, by the way, do I have any work schedule for the afternoon?" ”

Qi Xin said: "No! ”

Pang Xuelin said: "That's good, I have something to do with going to the Yuquan campus in the afternoon, if there is anything urgent here, you can call me directly." ”

"Oh, good!"

Qi Xin hurriedly nodded and wrote it down.

Pang Xuelin smiled: "Okay, it's not too early now, let's go to dinner together!" ”

"Wait a minute!"

Qi Xin hurriedly cleaned up the desk, then put on a navy blue tweed jacket and followed with some excitement.

The two went out together.

Walking on the road, although Qi Xin's height is only one meter and his sixties, he stepped on high-heeled boots, just to the root of Pang Xuelin's ears.

The combination of handsome men and beautiful women, coupled with Pang Xuelin's own popularity, has an almost 100% return rate on the road.

The two walked and talked.

Qi Xin said: "By the way, junior brother, the World Conference of Chinese Mathematicians is about to open in three days, the organizer has already booked a ticket for us, we will fly to Beijing the morning after tomorrow, don't forget it then." ”

Pang Xuelin was slightly stunned, and asked suspiciously: "You also want to go together?" ”

"Of course, I'm your work secretary, where you go, I'm definitely going to follow!"

"Oh, that's fine."

Pang Xuelin smiled a little embarrassedly, and it seemed that he had asked Yao Bingxia to climb the Great Wall together.

After this topic diverged, the two talked and laughed, and after eating together in the cafeteria, Pang Xuelin said goodbye to Qi Xin and drove to the Yuquan campus.

……

As soon as he came to the door of the laboratory building of the School of Materials Engineering, Pang Xuelin saw that Xu Xingguo and Li Changqing had been waiting at the door of the laboratory building for a long time.

"Professor Pang, long time no see!"

"Dean Xu, Professor Changqing, long time no see!"

Pang Xuelin, Xu Xingguo, and Li Changqing shook hands respectively, and the three of them exchanged pleasantries for a while, and then went directly to Li Changqing's carbon materials laboratory.

In the laboratory, Li Changqing was showing Pang Xuelin the characterization report of high-purity carbon nanotubes.

"Professor Pang, you see, this is the characteristic peak of the carbon nanotube measured by Raman spectroscopy, because of the radial respiration vibration mode unique to the single-walled carbon nanotube, its characteristic peak appears in the range of 100 cm^-1 to 400 cm^-1, and its diameter is inversely proportional to the wavenumber of the characteristic peak...... Figure 1 shows the topography of carbon nanotubes with a diameter of 10 nanometers and a length of 5 microns...... Figure 2 is a transmission electron microscope photograph of the adhesion of RuO2·xH2O to carbon nanotubes, according to the analysis, the RuO2·xH2O obtained by continuous stirring during the reaction precipitation process and drying annealing at about 150e is amorphous. In our experiments, a mixture of amorphous RuO2·xH2O and nanocrystals was formed because the surface of the carbon nanotubes provided a substrate for RuO2·xH2O nucleation during the reaction precipitation. With the addition of RuO2·xH2O, RuO2·xH2O began to transform into amorphous. Fig. 3 shows the X-ray diffraction patterns of two different amounts of RuO2·xH2O......"

Li Changqing explained for a long time before he sighed: "Professor Pang, I really didn't expect that according to your experimental method, the results obtained would be so good, and there is no problem with this paper being directly published in the main journal Nature." ”

Xu Xingguo, the dean of the School of Materials Engineering on the side, also smiled and said: "Yes, Professor Pang, you are the first time that our School of Materials Engineering has been established for so many years, and your doctoral dissertation has reached the CNS level. ”

Pang Xuelin smiled and said: "Thanks to everyone's help, this project will be so smooth, so let's celebrate the success of the project, I will invite everyone to have a big dinner outside the building in the evening!" ”

"Long live Professor Pang!"

In the laboratory, the young experimental dogs who were pulled into the project team immediately cheered.

After a few months of busyness, changing a paper in the main journal of Nature, even if it is only two or three works, is also a strong stroke in their personal resume.

After reading the characterization report of high-purity single-walled carbon nanotubes, Pang Xuelin glanced at Li Changqing and Xu Xingguo, and the three of them came out of the laboratory together.

Xu Xingguo said a little strangely: "Professor Pang, is there anything else?" ”

Pang Xuelin took out a document from his briefcase, handed it to Li Changqing and said, "Professor Changqing, you take a look at it first." ”

Li Changqing looked at it for a while, and soon let out a sigh of surprise.

Xu Xingguo was a little curious: "Changqing, what is this?" ”

Li Changqing handed the document to Xu Xingguo and said, "Dean Xu, you can also take a look!" ”

Xu Xingguo took the document, and when he looked at the title, he couldn't help but be taken aback: "Carbon nanotube composites, carbon-based chips, high-purity graphene projects? ”

Pang Xuelin nodded and said, "Dean Xu, after you finish reading it first, we'll talk later." ”

Half an hour later, Xu Xingguo, Li Changqing, and Pang Xuelin gathered in a conference room in the experimental building.

Pang Xuelin said: "Dean Xu, Professor Changqing, I think so, since the high-purity electronic-grade single-walled carbon nanotubes have been made by us, then we can consider continuing on this road, I hope that the School of Materials Engineering can set up three project teams, the first project is to prepare carbon nanotube CMOS on the basis of high-purity carbon nanotubes, and then research in the direction of carbon-based chips, and the second project is to prepare high-strength carbon nanotube fiber materials, this material, Theoretically, it is more than ten times higher than the world's highest strength material, and has important uses in the aerospace and defense industries. The third, the high-purity graphene project, not to mention, I think everyone understands the meaning. ”

Xu Xingguo nodded, and then frowned: "Professor Pang, your idea is very good, but the scientific research funds required for these projects are astronomical, and I am afraid that we can't get so much by relying on our school alone, right?" ”

Pang Xuelin smiled slightly and said: "I can pull 100 million scientific research funds from the enterprise, in addition, I will go to Beijing in two days, and I will find a way to find the Ministry of Science and Technology and the Ministry of Industry and Information Technology to ask for funds!" ”

Xu Xingguo and Li Changqing glanced at each other, Xu Xingguo pondered for a moment, nodded and said: "Professor Pang, as long as you can get the 100 million funds you said, I will take over the carbon nanotube CMOS project, and here in the school, I can find a way to get another 20 million!" As for carbon nanotube fibers and graphene materials, it's still up to Professor Changqing! ”

Pang Xuelin smiled: "Okay, then wait for my news!" ”

That night, Pang Xuelin directly hosted a banquet for Xu Xingguo, Li Changqing and all the members of the project team in the outer building, and after eating, Pang Xuelin drove directly to the villa where his parents lived.

As soon as I entered the door, my mother Mei Yuqing was doing yoga in the living room following the teaching content on TV, and my father Pang Yongnian was nowhere to be seen.

Mei Yuqing said a little strangely: "Xiaolin, why are you here?" ”

His son's temperament is clear to him, Pang Xuelin rarely goes home, especially after school classes, he basically lives in the school, and he goes home like a guest on weekdays.

Pang Xuelin has experienced so many worlds, and his personality is relatively mature, and he smiled when he heard this: "Mom, I live at home at night, what about my dad?" ”

Mei Yuqing said: "Your dad is upstairs in the study." ”

"I'll talk to my dad about something!"

With that, Pang Xuelin went upstairs directly.

Mei Yuqing said below: "Xiaolin, have you eaten, do you want to get you something to eat?" ”

"No need, my colleague and I came back from dinner!"

"This stinky boy!"

Mei Yuqing shook her head when she heard this, and continued to shift her attention to the yoga teaching content on the TV.

In the study, Pang Yongnian was sitting in front of the computer and surfing the Internet.

Seeing Pang Xuelin coming in, Pang Yongnian was slightly stunned, and said with some doubts: "Xiaolin, why are you back?" ”

Pang Xuelin sat down directly on the chair opposite the desk and said, "Dad, I want to borrow some money from you." ”

"Oh, borrow money, how much?"

Pang Yongnian is a little strange, since he was a child, his son almost never took the initiative to ask him for money, which is the first time in the world.

He glanced at Pang Xuelin, then picked up the teacup on the table and took a sip gently.

Pang Xuelin said: "One hundred million! ”

When Pang Yongnian heard this, he almost squirted out the tea in his mouth, raised his head and said, "What? ”

Pang Xuelin smiled slightly and said, "I want 100 million!" ”

Pang Yongnian frowned, he knew that Pang Xuelin was not a targeted person, so he couldn't help but be a little puzzled: "Xiaolin, what do you want so much money for?" ”

Pang Xuelin said: "Do an experiment!" ”

Then, Pang Xuelin introduced the high-purity carbon nanotube project and the graphene project to Pang Yongnian.

Pang Yongnian: "......"

"Xiaolin, are you sure these two things can make money? Don't bully your dad for not knowing how to do it, even if your lab really makes it, there must be a long way to go before the real product happens, and if you have to wait for ten or eight years to blossom and bear fruit, then the money is no different from playing in the water. ”

Pang Xuelin smiled and said, "Dad, I understand what you say, but I can tell you for sure that I won't cheat my own family." Carbon-based chips and graphene materials aside, let's take high-strength carbon nanotubes as an example, as long as you are willing to invest, I guarantee that within three months, high-strength carbon nanotubes will be mass-produced, and as long as you invest this money, the patent will be in our own hands at that time. It's the only deal in the world, and I think you know better than I know how much value it has. ”

Pang Yongnian frowned and said, "That's right, but can you guarantee that it will be done within three months?" ”

Pang Xuelin smiled slightly and said: "Dad, I haven't said anything big since I was a child, not to mention high-strength carbon nanotubes, even if it is graphene and carbon nanotube CMOS, I can guarantee that it will be made within a year." We are our own family, so I will give you this investment opportunity, if you don't invest, I think I can also convince other people to get this money! ”

Pang Yongnian pondered for a moment and said, "Okay, I'll vote!" ”
