Ulrika glanced at the figure in the laboratory again, but at this time, the people inside were all wearing dustproof suits and doing experiments, and when she didn't find out which one was Zheng Jianguo for a while, she heard this person say with a face full of surprise: "The recommendation letters of the three professors? and Professor Philip?"

As the world's top engineering college, MIT recruits many graduate students every year, but the acceptance rate is only about 2% compared to the huge base.

It's hilarious that Professor Thomas himself wrote a letter of recommendation to himself, but Philip is a Nobel laureate, and in the eyes of the school board, his letter of recommendation is enough to open the doors of the school to any student, not to mention that Zheng also relied on the discovery of Helicobacter to become a "special teaching assistant" at Harvard Medical School - this thing is still holding the title of a possible Nobel Prize candidate!

No school will dislike this kind of Nobel Prize candidates, especially when this is still a "scholar" who is less than 18 years old, so as the school board of MIT, after a simple discussion, Zheng Jianguo opened the door to graduate school.

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

"OK, I'll take a look?"

Thomas, who was wearing a mask and hood, was tightly wrapped all over his body, and when he saw Zheng Jianguo get out of the way, he went to the microscope, stared at the bright part of the light inside with wide blue eyes, 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 to take it, and saw that the other people in the laboratory who were tearing the tape looked at each other, the masks and hoods made it impossible to see the expressions of these people, but a pair of eyes of different colors but emitting the same light emerged with great eagerness, of course, whether these people could go under the microscope to see was not up to him: "Then based on the analysis of the saliency characteristics of the graphite material, the subject matter on the substrate was detected by the Lahan spectrometer."

It can be confirmed that there is a lower defect D peak at around 1300 cm-1, while the G peak at 1600 cm-1 is generated by the in-plane vibration of the sp2 network of carbon atoms, and the 2D peak at 2700 cm-1 is due to the resonance scattering process of the two phonons.

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

"Well, Ika, a few of you go and take a look, and after looking at it, repeat the Rahan spectrum test. ”

Thomas turned his head to a few people who were tearing the tape, turned his head to look at Ulrika outside the laboratory, and said to Zheng Jianguo: "Zheng, you guide them to repeat the test." ”

"Yes, Professor Thomas. ”

Zheng Jianguo's gaze swept over Ulrika at the door of the laboratory, turned to the "strong men" who had silently watched the microscope, and heard someone say: "Zheng, how did you find out that you used this method to find the graphite layer?"

"There was a place in my semester assignment that needed to be corrected, and there was no correction fluid, so I picked up the tape and glued off the handwriting on it, and just when I wanted to throw it away after I glued it, well, I remembered the last time I did the experiment, I saw someone throw the tape with graphite powder stuck in the trash, and I asked myself what the experiment was doing, and what I was looking for was only in the graphite on my hands?"

Zheng Jianguo is talking about things that most of the students in this family have done, and they can't be erased or crossed out if they want to modify it when the correction fluid is gone, so what they can do at this time is to find a way to remove the wrong part, which instantly resonated with others: "Your idea is so great, it's amazing-"

"We've more or less grinded graphite sheets, but the tape that sticks off is just thrown away—"

"Zheng, your focus is really different, well, that's how you discovered Helicobacter—"

"Zheng, let's have a meal together at noon to celebrate your today—no, to celebrate this amazing discovery of yours!"

"Zheng, I feel that you had better write your paper now, this is what you should do at the moment, and we can help you get started. ”

"Yes, you did this test yourself, although you have been instructed by others before, but the test the day before yesterday was done by you alone-"

"In the future, after you follow the professor to do experiments, then there may not be a chance for you to write-"

"Zheng, after writing, I can ask Professor Thomas to help revise it and then vote—"

After a series of reminders, Zheng Jianguo didn't expect these "strong men" to be so enthusiastic, and the cheeks of Shen Yunhui and Tao Ye flashed in his mind, and he immediately smiled: "Okay, then you guys continue to be busy, I'll start writing now, and I'll invite everyone to dinner when I'm done——"

"Ah, this, what's embarrassing—"

"Zheng, I'm so embarrassed about this-"

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

"Yes, you can eat at any time—"

There were bursts of admonitions one after another, Zheng Jianguo also found the notebook and opened it on the small table next to him, took out a pen and began to draft on it, and a few people in front of the microscope behind him looked at the tearing and tearing test, with the help of the experience of writing a lot of papers, it was quickly finished, and the remaining data needed to be filled in after the repeated test came out, turned to look at Thomas who came in and said: "Professor Thomas, I plan to publish today's repeated test, 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, went to the glass next to the door, pressed the paper on it, knocked on the glass to attract the attention of people outside, and pointed to the words on the note.

Seeing that the people outside nodded and left, Thomas turned around to Zheng Jianguo and looked at the manuscript he had copied again, and said with a smile: "Yes, yes, it's a very standard way of writing papers, but some of the words in this can be replaced by simple spelling, such as this——"

Compared with ordinary graduate students, Zheng Jianguo did not write many papers, including "A Preliminary Study of Helicobacter" that made a name for himself and sent Chinese to the "Lancet", and only three papers were published in half a year to this time, but these three articles were all published on the "Lancet" without exception, not to mention the quality, and pulling out one article at random is enough for ordinary doctors to eat for a lifetime.

It's just that all those who know Zheng Jianguo's research understand that he is eating his old book, since he came to the United States, he has never entered the laboratory of the Department of Gastroenterology, and this is the main reason why he donated to build a laboratory in Qi Provincial Medical College.

Once, Zheng Jianguo thought about when to release the discovery of graphene, a nuclear bomb, which was a shortcut he thought of when he hadn't found out Helicobacter in China, but after going to medical school, he seemed to be able to make his wishes come true all the way to this time.

Considering that the reporters who have come to him recently are more and more inclined to the silver crisis and the rise in gold, as well as Camille Silk and games, Zheng Jianguo also knew that he couldn't wait any longer, so he threw out the graphene discovery after thinking about it for a month, which was completely put under the magnifying glass of the FBI.

Yes, Zheng Jianguo thinks that if the graphene is released, then the legendary FBI will come to the door as quickly as possible, and even check his research from beginning to end, so in all the links from elective courses to exposing the existence of graphene, only the elective basic physics course and pointing out the graphene are the results of his initiative at the two key points on the tape, and the other graphite, including the test material, was selected by Celia, and the degree of cooperation even made him think that this sister was the same as himself, belonging to the reborn?

Until the end of the research, Brady glued the tape of graphite powder and threw it into the trash, Zheng Jianguo did not immediately uncover the mystery of the darkness under the lamp, until he went back and waited for more than a month, and made sure that there would be no major problems in his "discovery process" from beginning to end, so he decided to take this step.

Originally, the study of graphene was based on the integer quantum Hall effect and the fractional quantum Hall effect at room temperature as the starting point, but I did not know that although the Hall effect was discovered by Hall in 1879 a hundred years ago, it was not until 1980, that is, next year, that the German von Klitzing discovered the whole quantum Hall effect, and won the Nobel Prize five years later in 1985.

The fractional quantum Hall effect was discovered by Chinese physicists Cui Qi and Sttmore in 1982, and supplemented by a new theory proposed by Lauvrin the following year, and finally formed the fractional quantum Hall effect, which is often called the quantum Hall effect, and won the Nobel Prize in physics in 1998.

Based on this, due to Zheng Jianguo's subjective ignorance of the operation that only knows what it is, it has led to a series of jaw-dropping results, of course, at this time, according to Professor Thomas, he has revised the paper, and he is still doubting whether this can be published: "This article can be sent to the college newspaper, right?"

"I'll have someone cast it for you. ”

Thomas smiled mildly and took the paper into his arms, then looked at the "strong men" who were tearing the tape next to him, and said, "Are the spectrometer results out?"

"I'm still waiting to take pictures, and it should be okay for another half an hour. ”

One of them spoke, Thomas turned his face to look at Zheng Jianguo, and said: "Then you stare at the point here even if you study, I'll go back to the office first, and you will send me the results when you have them." ”

"Okay, teach you to walk slowly. ”

Zheng Jianguo went to the door to see Thomas away, and found that he didn't say anything until he changed his clothes and went out, but someone came from outside, and there was a strange camera hanging around his neck.

The paper was taken away a long time ago, and when the results of the spectrometer came out, Zheng Jianguo and these people who only saw their faces became familiar: "Zheng, the peak of these twenty sets of results is similar to what you said, how many sets did you do yesterday??"

"Fifty. ”

Zheng Jianguo remembered his busy work yesterday, and at this point he had a preliminary harvest: "You have worked hard-"

"This is not called hard work, the effort without harvest is called hard work, let's send the results to the professor and go to dinner, I know that it is good to have a Chinese restaurant, what is it called yunnanmixian?"

The person who spoke was a little pompous, but Zheng Jianguo was already familiar with the pompousness of some Americans expressing their feelings, and then remembered that the place he was going to was a Chinese restaurant, so he said, "Go to Chinatown? That's a bit far-"

"No, it's just north of the school, and it's only a few minutes by car - let's pack up the lab, it's pretty much there. ”

With this person's suggestion, someone had already dragged a big guy to the side to connect the power and turn it on, and the whining vacuum cleaner began to clean up, and the six of them didn't take much time to clean up, and after changing their respective clothes, they knew each other: "I'm Lawrence Beuys, he's Wallace Beams, this is Bodie Chalino, Colwin Kirkby, Lancelot Arman, we're all juniors in the physics department, it's time to be a senior, it's nice to meet you, Zheng-"

Lawrence Boyce was shorter, but his face was thick and wide-eyed: "We've heard of you for a long time—"

Wallace Beams folded his hands together and nodded, "Yes, the youngest medical student at Harvard Medical School—"

Bodie Chalino with golden curls: "I didn't expect your observation to be so keen—"

Colwin Kirkby's face was full of freckles: "We've been to the lab to beat people, and we've seen the tape that others threw away—"

Lancelot Arman was the tallest, and at 1.9 meters, he looked down at Zheng Jianguo and said, "But no one noticed what was thrown away, and they, including us, seemed to think that those things were not important." ”

"Now that I think about it, it's supposed to be the herd effect, subservient to authority and not having a mind of one's own—"

Lawrence Boyce snapped his hand and snapped his fingers, turned to look at the empty corridor and pressed the button at the elevator entrance, and then he spoke again: "Zheng, you have a car, right? Let's drive, go back quickly." ”

"Yes, a Plymouth sedan—"

Zheng Jianguo shrugged his shoulders and said that he hadn't eaten in a Chinese restaurant since he came here for half a year, and most of them were either in school or in his residence, and occasionally he looked at the street as if he was looking at the flowers, as if he had some resistance to the Chinese restaurant in his heart.

It didn't take long for Zheng Jianguo to know what the resistance in his heart was, and the boss who spoke in stiff Mandarin obviously recognized him: "Zheng Jianguo, do you know that studying abroad is to stay after studying?
