Great Power

Ulrika glanced at the figures in the laboratory again, but the people inside were all wearing dust-proof suits during the experiment. When they didn’t find out which was Zheng Jianguo for a while, they heard this person say. A face full of surprise: "Recommendations from three professors? And Professor Philip?"

As the world’s top engineering college, MIT recruits a lot of graduate students every year, but the acceptance rate is only about 2% compared with the huge base. If you want to enter this school for graduate studies, it’s super high Academic performance is only a basic requirement. In addition to this, it is also required to have certain academic results, and the most important thing is to obtain letters of recommendation from three professors.

It is funny that Professor Thomas wrote himself a letter of recommendation. However, Philip is the Nobel Prize winner. In the eyes of the school board, his letter of recommendation is enough to open the school’s doors to any student, let alone Zheng Huan. Relying on the discovery of Helicobacter he became a "special teaching assistant" at Harvard Medical School-this guy still holds the title of a possible Nobel candidate!

No school will dislike this kind of Nobel Prize candidates, especially when this "student bull" is still less than 18 years old, so after a simple discussion as the school board of the Massachusetts Institute of Technology, it gave Zheng Jianguo Opened the door to graduate students.

Of course, Zheng Jianguo also knows that the reason why the famous Massachusetts Institute of Technology is so generous is the part of 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. --Floor."

"OK, let me observe?"

Thomas, who was wearing a mask and headgear and wrapped his whole body tightly, said that when he saw Zheng Jianguo step away, he went to the microscope. His wide-eyed blue eyes looked at the bright part inside and said, "The bright colors are the organic matter on the tape?"

"Yes, the higher the color, the more organics."

Zheng Jianguo took it, and saw other people in the laboratory who were tearing tape looking together. The masks and headgear made people unable to see the expressions of these people. It was just a pair of eyes with different colors but the same light. Very eager, of course, whether these people can go to the microscope to see it is not his decision: "Then, based on the analysis of the salient characteristics of the graphite material, the Rahan spectrometer is used to detect the target on the substrate.

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

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

"Well, Ica, a few of you go and have a look, and repeat the Raham spectroscopy after reading."

Thomas turned his head and said to some of the tape-tearers. He turned his head and glanced at Ulrika outside the laboratory, and said to Zheng Jianguo: "Zheng, you can instruct them to repeat the experiment."

"Okay, Professor Thomas."

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

"There was an area in my semester homework that needed to be revised. It happened that there was no correction fluid. I picked up the tape and stuck the handwriting on it. Just when I wanted to throw it away, I remembered the last time I did it. During the experiment, I saw someone throw the tape with graphite powder into the trash can. I asked myself what the experiment was doing. Is the only thing I was looking for in the graphite on my hand?"

Zheng Jianguo is talking about what most of the students in this household have done. If the correction fluid is gone, if you want to modify it, you can’t erase or cross it off. So what you can do now is to find a way to remove the wrong part. It instantly resonated with other people: "This idea of ​​you is so, amazing—"

"We have more or less polished the graphite flakes, but the sticky tape was just thrown away—"

"Zheng, your focus is really different. Well, your Helicobacter was also discovered in this way—"

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

"Zheng, I feel that you'd better write the paper now. This is what you should do the most. We can help you."

"Yes, you did this experiment yourself. Although you have been mentored by others before, you did the experiment the day before yesterday by yourself—"

"After you do experiments with the professor in the future, you won't necessarily have the opportunity to write a pen—"

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

After repeated reminders, Zheng Jianguo did not expect that these "strong men" would be so passionate. The cheeks of Shen Yunhui and Tao Ye appeared in his mind, and he immediately smiled and said, "Okay, then you continue to be busy. I will start to write and finish writing. I invite everyone to dinner—"

"Ah, this, how embarrassed--"

"Zheng, this is so embarrassing——"

"Zheng, you should write it first--"

"Yes, you can eat anytime you eat—"

There were repeated urges, Zheng Jianguo also found the notebook and opened it on the small table next to him, took out the pen and began to draft drafts on it, and the few people behind him in front of the microscope looked at the tear test. , With the help of the experience of having written a lot of papers, I quickly finished it, and the remaining data needs to be repeated after the test is out before filling in. Turning to look at Thomas who came in, "Professor Thomas, I plan to Repeat the experiment and publish it, but some photos need to be taken—"

"Wait, I'll call the photographer over."

Thomas, who had just entered the laboratory, immediately picked up the pen and paper next to him and wrote. When he reached the glass beside the door, he pressed the paper on it, knocked on the glass to attract the attention of outsiders, and pointed at the words on the note. Pointed.

Seeing people outside nodded and left, Thomas turned back to Zheng Jianguo and looked at the manuscript that he had copied again. He smiled and said: "Yes, not bad, very standard way of writing papers, but there are some things inside. Words can be replaced with Jianpin, such as this—"

Compared with ordinary graduate students, Zheng Jianguo has not written many papers, including "A Preliminary Study of Helicobacter", which became famous and published in Chinese on "The Lancet". By now, he had only published three papers in half a year. These three papers, without exception, are all posted on The Lancet. I won’t say anything about the quality. Any one pulled out is enough for ordinary doctors to eat for a lifetime.

It’s just that everyone who understands Zheng Jianguo’s research understands that he is eating his own money. Since he came to the United States, he has never entered the laboratory of the gastroenterology department, and this is also the main reason for his donation to build a laboratory at Qi Provincial Medical College The reason is that you didn't let me in, so I just built one myself until I got the elective basic physics experiment course.

Once, Zheng Jianguo thought about when to release the discovery of the nuclear bomb level of graphene. This is the shortcut he thought of when he had not found out the Helicobacter bacteria in China, but he seemed to be able to take it after he went to medical school. I have come all the way to this time.

Considering that the reporters who came to him recently are increasingly inclined to the silver crisis and the rise in gold, as well as Camille and the game, Zheng Jianguo knew that he could not wait any longer, so he found out the graphene after thinking about it for a month. Throw it out, and put yourself completely under the FBI's magnifying glass.

Yes, Zheng Jianguo thinks that if 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 he is in the process from elective courses to disclosure. Among all the links in the existence of graphene, only taking the basic physics course and pointing out that graphene is on the tape are two key points that belong to his initiative. The other graphite, including the test material, is selected by Celia, and the degree of coordination Once made him think that this sister is also a rebirth like himself?

Until the end of the study, Brady put the graphite powder tape into the trash can, Zheng Jianguo did not immediately reveal the heavy black under the lamp, until he went back and waited more than a month to determine his "discovery process" "There will be no major problems from beginning to end, so I decided to take this step.

In the original history, the study of graphene was based on the integer quantum Hall effect and the fractional quantum Hall effect under normal temperature conditions as an entry point, but it is unknown that the Hall effect was discovered by Hall in 1879, a hundred years ago. However, it was not until 1980 that is next year that German von Klitzing discovered the integer quantum Hall effect, and he won the Nobel Prize in 1985 five years later.

The fractional quantum Hall effect was discovered in 1982 by Chinese physicists Cui Qi and Stermore, and was supplemented by a new theory proposed by Laughlin the following year, which eventually formed the fractional quantum Hall effect. Said quantum Hall effect, and won the Nobel Prize in Physics in 1998 for it, and the graphene that appeared after the tear tape fully verified the Nobel Prizes obtained by the theoretical research of the first two, a total of three Nobel Prizes It can be regarded as opening a new door to condensed matter physics.

Based on this, due to Zheng Jianguo’s subjective ignorance of the operation that only knows the truth and does not know the reason, it led to a series of shocking results. Of course, he revised the paper according to Professor Thomas at this time, and he still doubts this ability Can’t post: "This article can be posted to the college newspaper, right?"

"I'll let someone vote for you."

Thomas showed a gentle smile and carried the paper into his arms, then looked at the "strong guys" who were tearing the tape next to him, and said, "Did the spectrometer results come out?"

"Still waiting to take pictures, after another half an hour should be fine."

One of them said, Thomas turned his face to look at Zheng Jianguo, and said: "Then you can just stare here, even if you are studying, I will go back to the office first, and you will send me the results."

"Okay, teach you to walk slowly."

Zheng Jianguo went to the door to escort Thomas away. He found that he didn't say anything until he changed his clothes and went out. Someone hurried up outside, with a weird camera hanging around his neck. He was ready early. He had snapped shots in front of the microscope, and he had learned a lot by the side.

The paper was taken away a long time ago. When the results of the spectrometer came out, Zheng Jianguo and these people who only saw faces became familiar: "Zheng, the peak of these 20 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 by now he has made preliminary gains: "You have worked hard—"

"It's not hard work, but hard work is hard work. Let's send the results to the professor and eat. I know that a Chinese restaurant is good. What is yunnanmixian?"

The speaker's actions were a bit exaggerated, but Zheng Jianguo was already familiar with the exaggeration of some Americans expressing feelings, and then remembered that the place he was going was a Chinese restaurant, so he said: "Go to Chinatown? That's a bit far away—"

"No, it's north of the school. It only takes a few minutes to drive-let's clean up the laboratory, it's almost time."

Following this person’s suggestion, someone has dragged a big guy next to plug in the power and turned on the whirring vacuum cleaner. The six people did not take much time to clean up, and they changed their clothes. Even if I knew it: "I’m Lawrence Boyce, he’s Wallace Beams, this is Bodie Charinault, Colwyn Kirkby, Lancelot Arman, we They are all juniors in the physics department. They should be seniors now. I am glad to meet you, Zheng—

Lawrence Boyce is relatively short, with thick eyebrows and big eyes: "We've heard of you a long time ago—"

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

Bodie Charinault had golden curly hair: "I didn't expect your observation to be so sharp—"

Colwyn Kirkby’s freckles on his face: "We have also been to the laboratory to beat people, and we have also seen tape that others throw away—"

Lancelot Arman was the tallest. He was 1.9 meters tall and looked down at Zheng Jianguo Road: "But no one noticed what was thrown away. They-including us, seemed to think that those things were not important."

"Thinking about it now, this should be the herd effect, obeying authority without having your own thinking--"

Lawrence Boyce slapped his hand and snapped his fingers and said, turning around and looking 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 and go. Come back soon."

"Yes, a Plymouth car—"

Zheng Jianguo shrugged and said that he hasn’t eaten in a Chinese restaurant for half a year since he came here. There was any resistance to the Chinese restaurant. At this moment, he heard Lawrence talk about crossing bridge rice noodles, and he was moved.

It was just that the six people drove three cars to the Chinese restaurant that Lawrence called and sat down. It didn’t take long for Zheng Jianguo to know what was going on in his heart. The boss who spoke blunt Mandarin obviously recognized him: "Zheng Jianguo , Did you know that studying abroad means staying after studying? Will you stay?"
