Rebirth 2002: Nano Life

"You are Chen Yizhe?" Although Fu Weiqiang had already learned in the letter that the other party was a high school student, he was still surprised when they met. How can a high school student become interested in graphite, and how can he think of using tape to peel off graphite? Even if he peels off graphite, there is no hardware condition to detect whether its thickness is a single layer. There are too many doubts.

Chen Yizhe met Fu Weiqiang in the teacher's office. The first meeting left a deep impression on Chen Yizhe: he is tall, at least 185cm, and in his fifties. Maybe because he stayed in the laboratory all the year round, he looked at him. His face is a little pale, with thick lips, high cheekbones, deep eyes, and a serious expression, which puts a lot of pressure on others.

Chen Yizhe nodded and asked, "Who are you?"

"I'm a professor at the School of Materials Science and Engineering, Beijing UCAS. My name is Fu Weiqiang." Fu Weiqiang paused and continued, "Did you write a letter to our laboratory before?"

Fu Weiqiang's voice was strong and strong, and it gave people a sense of solidity.

Chen Yizhe nodded again and said with a smile, "I didn't just send it to the National University of Science and Technology. I sent letters to several top universities in materials science in China, but you are the only one who came here in person."

Hearing the young man say that several colleges and universities have sent letters, Fu Weiqiang smiled and said, "Then it seems that I have come right. It should be class time now, why don't we find another place to talk after you finish class?"

Chen Yizhe shook his head and said, "No need, I just dropped out of school, and the time is still free now."

Principal Lin and the others, who were standing on the side with these words, were all embarrassed. They didn't know what to say. They still didn't know why the people from the National University of Science and Technology came here, and what was the graphene discovered by Chen Yizhe? Moreover, the words of Principal Lin have already been said, and Director Huang is still in school. Even if he wants to go back, he has to consider the consequences.

"Mr. Li Li, what's going on?" At this time, the teachers in the office were a little confused when they heard the news that Chen Yizhe would suddenly drop out of school. With a city champion, why did the school let him drop out?

Li Li shook her head, and didn't know how to explain it. A seed that had the opportunity to grow into the top student in the college entrance examination was suddenly gone. She was extremely unwilling, but what could she do if the principal said it? In a high school like a small county town, the principal's authority is still extremely high.

"What's the matter?" Fu Weiqiang had a chat with the teacher in the office when he was waiting. Basically, the teacher said that Chen Yizhe was very smart, and his grades were also the top in the school. Why did he suddenly drop out of school?

"It's a long story." After Chen Yizhe finished checking the time on his phone, he said to Fu Weiqiang, "It's almost noon now, why don't we go out to find a place to eat and then talk slowly?"

Before leaving, Chen Yizhe walked up to Li Li and several teachers who taught him, and said thank you for his understanding and care for him over the past few months.

When passing by Huang Shaoyang, Chen Yizhe smiled strangely at him. That smile made Huang Shaoyang feel a little gloomy. After a night of pain last night, Huang Shaoyang felt that Chen Yizhe might have poisoned him. He had a few guesses. The points were right, but he didn't know that Chen Yizhe had given him another poison, a poison that could never be hardened in this life.

Chen Yizhe called a taxi at the school gate and was going to take Fu Weiqiang to the Renmin Building for dinner. People's Building should be one of the most high-end restaurants in Fengba County. Many middle and high-level officials and businessmen in Fengba will come to eat here, especially when officials eat public funds here, it is already known to the whole county.

Although he has always responded to the above, Chen Yizhe remembers that the corruption in the People's Building was not published until a few years later in 2007. The "Xinhua Viewpoint" column reported the headline "Who is eating the people in the "People's Building"? " was adopted by hundreds of media and websites across the country, and set off a wave of discussion in the online media.

The fifth and sixth floors of the building are ultra-luxury restaurants. Although there are only two people, Chen Yizhe still booked a private room.

Chen Yizhe ordered five or six dishes first, and then handed the menu to Fu Weiqiang. Fu Weiqiang shook his head and said that was enough, Chen Yizhe smiled and ordered two more.

Coming out of school, Fu Weiqiang has been observing Chen Yizhe. The first impression is that he is a handsome young man. The first contact gives people a feeling of informality, free speech and behavior, and freedom. And a high school voice brought him to this kind of place, which also showed that the other party's family environment must be very good.

Chen Yizhe first poured a cup of Pu'er tea for Fu Weiqiang.

Fu Weiqiang found the tea cup, took a sip, and said with a smile, "I flew to Pengcheng last night, and I took the bus to Fengba early this morning, but I didn't drink a sip of water."

"Professor Fu, didn't I leave an email address on the letter? You can email me directly. It's a long journey from Kyoto to Fengba, a small county," Chen Yizhe said.

"Conversations without meeting will always feel empty. Besides, I'm also very interested in you, so I thought I'd come over when I have time in the next few days." Fu Weiqiang said in a low voice, "But why did you suddenly drop out of school?"

Chen Yizhe briefly explained the reason, "Although it is the school's decision to drop out, I have been thinking about dropping out in the past few months. The school's decision is just to let me go with the flow."

Fu Weiqiang frowned, "Why don't you choose to stay in school at your age?"

In particular, Fu Weiqiang dislikes the view that reading is useless by some Chinese people. In his era, because of the Cultural Revolution, knowledge became an original sin, and intellectuals were "stinking old nine"; People's congresses are ignorant, which is why it is said that it is better to sell tea eggs than to build atomic bombs; and in this era, due to the contradiction between the high expenditure on higher education and the increasingly weak return on education, the theory that reading is useless has once again risen. . As a scholar, Fu Weiqiang firmly believes that only reading can change your destiny, and only knowledge can give you a deeper understanding of the world.

"Professor Fu, what do you think the purpose of reading is?" Chen Yizhe asked suddenly, he answered without waiting for Fu Weiqiang to answer, "In my opinion, I think this question and the meaning of life have the same effect, the meaning of life. It is about survival and living, survival is for exploration, life is for feeling, and the purpose of reading is the same, for a better life in the future, and then a better feeling and understanding of the world.”

Chen Yizhe paused and continued to talk about Yabu, "I don't know if Professor Fu usually surfs the Internet, and has he heard of Soxia Engine and Yiyi Dongting Music website, these are two products of the company I founded last year, and the current prospects are Not bad. I don't mean to brag, I just want to make a point that even if I don't go to school, I can survive better than most people. Also, I always think that going to school It’s just one of the ways to read. It doesn’t necessarily mean that you can’t go to school, so you don’t go to study to learn new knowledge. The ancients all said that you can’t travel thousands of miles, and you don’t read thousands of books. !"

"What you said is reasonable, but after all, students are still immature. Taking the risk of leaving the school will only help them grow. The risk is still too great." Fu Weiqiang shook his head. As a scholar in the research room, His eloquence is only average.

"Then Professor Fu, do you think my mind is still mature?" Chen Yizhe laughed.

"You!" Fu Weiqiang glanced at Chen Yizhe and suddenly smiled, "I think you are a big kid! You said in your letter that graphite can be peeled off with adhesive tape. We tried many adhesive tapes according to your method. I only found a few of the 3m adhesive tapes, which can indeed peel off graphite, but the larger area is tens of microns, which is pitifully small compared to the area you sent."

Chen Yizhe wrote down the detailed steps in the letter. Fu Weiqiang followed his steps step by step, first placed the graphite crystal on the tape and folded the tape in half, pressed it, and then tore it apart. A layer of two-dimensional material fragments is naturally adhered to the torn tape, and then continue to tear 3-4 times on the surface of the fresh tape. Finally, place the silicon wafer on the two-dimensional material fragments, press hard for 60 s, and then remove the silicon wafer. So far, a layer of graphene two-dimensional material appeared on the surface of the silicon wafer. However, Fu Weiqiang found that no matter how the previous operation was improved, the final graphene area was still too far away from the one sent by Chen Yizhe.

Therefore, Fu Weiqiang believes that Chen Yizhe must have reservations, which is one of the reasons why Fu Weiqiang came to Chen Yizhe personally.
