Chapter 162

Ulrika looked at the figure in the laboratory again, but now the people inside were doing experiments in dust-proof clothes. When she couldn't find out which one was Zheng Jianguo for a while, she heard the man say with surprise: "the recommendation letters of the three professors? And Professor Philip? "

As the world's top engineering college, MIT recruits a lot of graduate students every year, but compared with that huge base, the admission rate is only about 2%. If you want to enter this school for graduate students, super-high academic performance is only the basic condition. In addition, you are also required to have certain academic achievements, Then the most important thing is to get a letter of recommendation from the three professors.

It's funny that Professor Thomas wrote a letter of recommendation to himself, but Philip is a Nobel Prize winner. In the eyes of the school board, his letter of recommendation is enough to open the door to any student, not to mention that Zheng has become a "special assistant" of Harvard Medical School by relying on the discovery of Helicobacter pylori - this product is still holding the title of a possible Nobel Prize candidate!

No school would dislike the large number of such Nobel Prize candidates, especially when he was still a "learning bully" under the age of 18. Therefore, after a simple discussion, the school board of directors of MIT opened the door for Zheng Jianguo to graduate students.

Of course, Zheng Jianguo also knows that the reason why the famous MIT is so generous is the purple area surrounded by bright colors on the substrate under the optical microscope in his pupil: "this substrate should show two to three layers of graphite - layers."

"OK, let me observe?"

Thomas, who was wrapped tightly with a mask and Headcover, said that when he saw Zheng Jianguo get out of the way, he came to the microscope, stared at the bright color inside and said, "the bright color is the organic matter on the tape?"

"Yes, the higher the color, the more organic matter."

Zheng Jianguo opened his mouth and saw that other people in the laboratory were looking at them. The masks and headgear made people unable to see their expressions, but the eyes with different colors but the same light emerged with incomparable eagerness, Of course, whether these people can go under the microscope is not his decision: "then, based on the analysis of the significant characteristics of graphite materials, rahan spectrometer is used to detect the subject matter on the substrate.

It can be confirmed that there is a low defect D peak at about 1300cm-1, while the G peak at 1600cm-1 is generated by the in-plane vibration of carbon atom SP2 network, and the 2D peak at 2700cm-1 comes from the resonance scattering process of two phonons.

I think the greater the ratio of the height of 2D peak to the height of G peak, the thinner the number of layers of graphite, and the thinner the number of layers of graphite, the sharper the shape of 2D peak, and the height of 2D peak of single layer is about 1-2 times that of G peak, and the 2D peak is sharper. "

"Well, IKA, you guys go and have a look. After that, repeat the rahan spectrum test."

Thomas turned his head and said to several people who tore the tape. He turned his head and looked at Ulrika outside the laboratory, and then said to Zheng Jianguo, "Zheng, you guide them to repeat the test."

"All right, Professor Thomas."

Zheng Jianguo glanced at Ulrika at the door of the laboratory, turned to the "strong men" who silently looked at the microscope, and heard someone say, "Zheng, how did you find this way to find the graphite layer?"

"There was a place in my term work that needed to be modified. There was no correction liquid. I picked up the tape and pasted the handwriting on it. When I wanted to throw it away after I pasted it, well, I thought of the last experiment. When I saw someone throw the tape with graphite powder into the trash can, I asked myself what I was doing in that experiment, Is what you're looking for only in the graphite in your hand? "

Zheng Jianguo is talking about what most students in this family have done. If you want to modify it, you can't paint it or cross it out. So what you can do now is to find a way to remove the wrong part, which immediately aroused the resonance of others: "your idea is really, great -"

"We have more or less ground graphite flakes, but the adhesive tape is thrown away -"

"Zheng, your focus is really different. Well, that's how you found Helicobacter -"

"Zheng, let's have a lunch together at noon to celebrate your today - no, celebrate your amazing discovery!"

"Zheng, I think you'd better write your paper now. This is what you should do at present. We can help you."

"Yes, you completed the experiment yourself. Although you were instructed by others before, you completed the experiment the day before yesterday -"

"After you do experiments with the professor, you won't have the chance to write -"

"Zheng, after writing, you can ask Professor Thomas to help revise it before you vote -"

After repeated reminders, Zheng Jianguo didn't expect these "strong men" to be so enthusiastic. Shen Yunhui and Tao Ye's cheeks flashed in his mind and immediately said with a smile: "OK, keep busy. I'll start writing now. After writing, I'll invite you to dinner -"

"Ah, this, how nice --"

"Zheng, I'm so sorry --"

"Zheng, you'd better write it first -"

"Yes, you can eat at any time -"

After repeated exhortations, Zheng Jianguo found his notebook and opened it on the small table next to him. He took out his pen and began to write a draft on it. Several people in front of the microscope behind him looked at it and measured it. With the help of the experience of writing many papers, he quickly closed the end, and the remaining data needed to be filled in after repeated experiments, Turning to Thomas who came in, he said, "Professor Thomas, I'm going to publish today's repeated experiment, but I need to take some photos -"

"Wait a minute. I'll call the photographer."

Thomas, who had just entered the laboratory, immediately picked up the pen and paper next to him and wrote it. He went to the glass next to the door, pressed the paper on it, knocked on the glass, attracted the attention of outsiders and pointed at the words on the note.

Seeing that the people outside nodded and left, Thomas turned back to Zheng Jianguo, looked at the paper he transcribed again, and said with a smile: "yes, yes, it's a standard way of writing the paper, but some words in it can be replaced by simplified spelling, such as this -"

Compared with ordinary graduate students, Zheng Jianguo has not written many papers, including a preliminary study of Helicobacter, which is famous for sending Chinese to the lancet. Up to now, only three papers have been published in half a year, but these three papers are all published in the lancet without exception, not in terms of quality, Just pull out one article is enough for ordinary doctors to eat for a lifetime.

However, all those who know about Zheng Jianguo's research understand that he is eating his old money. Since he came to the United States, he has never entered the laboratory of Gastroenterology, which is the main reason why he donated to build the laboratory in Qi provincial medical college. If you don't let me in, I'll build one myself until I get together with the elective basic physics experiment course.

Once, Zheng Jianguo thought about when to release the discovery of graphene, a nuclear bomb. This was the shortcut he thought of when he had not found Helicobacter in China. He just seemed to be able to achieve what he wanted after going to medical school.

Considering that the journalists who came to him recently were more and more inclined to the silver crisis, the rise of gold and Camille silk and games, Zheng Jianguo knew that he could not wait any longer, so he threw out the graphene discovery after considering it for a month, which was completely under the magnifying glass of the FBI.

Yes, Zheng Jianguo believes that if graphene is released, the legendary FBI will come to the door at the fastest speed, and even check his research from beginning to end. Therefore, in all links from elective courses to revealing the existence of graphene, only basic physics courses and pointing out that graphene is on the tape are the results of his initiative, Other graphite materials, including experimental materials, were selected by Celia. The degree of cooperation even made him think that this sister was a rebirth like herself?

Until the end of the research, Brady stuck the graphite powder tape and threw it into the dustbin. Zheng Jianguo didn't immediately uncover the heavy mystery under the light. Until he went back and waited for more than a month to make sure that there would be no big problems in his "discovery process" from beginning to end, he decided to take this step.

In the original history, the research of graphene was based on the integer quantum Hall effect and the fractional quantum Hall effect at room temperature. However, it is unknown that although the Hall effect was born 100 years ago and discovered by hall in 1879, it will not be discovered by German von klitsing until 1980, that is, next year, Five years later, he won the Nobel Prize in 1985.

The fractional quantum Hall effect was discovered by Chinese physicists Cui Qi and steimer in 1982 and supplemented by a new theory proposed by Laughlin the following year. Finally, it formed the fractional quantum Hall effect, which is often called the quantum Hall effect, and won the Nobel Prize in physics in 1998, In addition, the graphene appearing behind the torn tape fully verified the Nobel prizes won by the first two theoretical studies. A total of three Nobel prizes opened a new door to condensed matter physics.

Based on this, Zheng Jianguo's subjective ignorant operation of only knowing what he is and not knowing why has led to a series of startling results. Of course, at present, he still doubts whether this article can be sent to the college newspaper according to Professor Thomas's revised paper

"I'll have someone throw it for you."

Thomas showed a gentle smile, put the paper in his arms, then looked at the "strong men" who tore the tape next to him, and said, "did the spectrometer result come out?"

"I'm still waiting for photos. It should be OK in another half an hour."

One of them said that Thomas turned his face and looked at Zheng Jianguo and said, "if you stare here, it's even learning. I'll go back to the office first and send me the results."

"OK, Professor, take your time."

Zheng Jianguo bumped to the door to see Thomas off. He found that he didn't say anything until he changed his clothes and went out of the door. Instead, there was a man running outside with a strange camera hanging around his neck. He took pictures in front of the microscope he had already prepared, and he learned a lot of things nearby.

The paper was taken away long ago. When the results of the spectrometer came out, Zheng Jianguo and those who only saw faces became familiar: "Zheng, the peak value of these 20 groups of results is similar to what you said. How many groups did you do yesterday?"

"Fifty."

Zheng Jianguo thought of his busy work yesterday. By now, he had a preliminary harvest: "you've worked hard -"

"This is not hard work, but hard work without harvest. Let's send the results to the professor and go to dinner. I know there is a good Chinese restaurant. What's its name?"

The speaker's action was a little pompous, but Zheng Jianguo was familiar with the pompous expression of feelings of some Americans. Then he remembered that the place he was going to was a Chinese restaurant, so he said, "go to Chinatown? That's a little far -- "

"No, it's north of the school. It's only a few minutes if you drive - let's clean up the laboratory. It's almost the same."

With this man's suggestion, someone has dragged a group to the side, connected the power and turned on, and the whistling vacuum cleaner began to clean up. The six people didn't spend much time cleaning up. After changing their clothes, they even knew each other: "I'm Lawrence Boyce, he's Wallace beems, this is body chalino, Corwin Kirkby, Lancelot Aerman, we are all junior students in the Department of physics. Now we should be senior students. Nice to meet you, Zheng -- "

Lawrence Boyce was short, but with a thick face and big eyes: "we've heard of you for a long time --"

Wallace beames twisted his hands at a starting point and said, "yes, the smallest medical student at Harvard Medical School --"

Boddy chalino had blond curly hair: "I didn't expect your observation to be so sharp -"

Colvin Kirkby's freckles: "we've been to the laboratory to fight people, and we've seen tape thrown away by others -"

Lancelot Aerman, the tallest one meter nine, looked down at Zheng Jianguo and said, "but no one noticed what was thrown away. They, including us, seemed to think those things were unimportant at that time."

"Now think about it, this should be herding, obedience to authority without having your own thinking -"

Lawrence Boyce slapped his hands up and snapped his fingers. He turned and looked at the empty corridor. When he reached the elevator entrance and pressed the button, he said again: "Zheng, do you have a car? Let's drive. Go and get back. "

"Yes, a Plymouth car -"

Zheng Jianguo shrugged and said that he had not eaten in a Chinese restaurant for half a year since he came here. Most of them were either in school or in their residence. Occasionally, they looked at the Chinese restaurant as if they were watching flowers. It seemed that there was any resistance to the Chinese restaurant in his heart. At this moment, he was moved to hear Laurence talking about the rice noodles across the bridge.

But soon, with the six people driving three cars to the Chinese restaurant in Lawrence's mouth, Zheng Jianguo knew what the conflict was in his heart. The boss who spoke stiff Mandarin obviously recognized him: "Zheng Jianguo, do you know that studying abroad is to stay after studying?"? Will you stay? "
