Great Power

An hour later, Zheng Jianguo even operated the spectrometer with the microscope three times. Brady was still holding the graphite sheet and punching the grinder. Not to mention him now, even Celia felt something was wrong, holding it. Curious blue eyes looked at him, Ulrika also went to the sanding machine: "Have you finished it?"

"cough--"

Taking off the goggles and mask, Brady saw that his hand holding the graphite sheet was trembling slightly. Ulrika’s brown eyes fell on his hand, and his face flashed in a daze, “Sorry, I got you the wrong piece of graphite. This is high-density graphite. I will get you a piece of natural graphite. Here, this is it. You try?"

"what--"

Brady almost didn’t squirt out a mouthful of old blood. He looked at Ulrika’s innocent cheeks like a little girl, turned and looked at Zheng Jianguo, who was facing away from him and Celia and said something under the microscope. Putting on the goggles and mask, he took the graphite sheet, blinked and said, "This, isn't it high-density?"

"This won't be true. I just watched it. It must have been put in the wrong box in the last wave of experiments. You see that the luster of this piece of graphite is a little different from the previous piece—"

Suffocating her throat to explain happily, Ulrika finished speaking innocently, and Brady swallowed and swallowed, pinching the graphite sheet and rushing to the sander, but soon followed When he touched the sanding belt on the sanding machine, the heart he chose was also let go. The previous piece of grinding did not move for a long time. When this piece was touched, a large piece of graphite powder was grinded, and the hanging heart relaxed a little, which was useless. The meeting saw Ulrika holding a thin blade next to him: "Cut as thin as possible—"

Turning his head to look at Ulrika, Brady picked up a piece of adhesive tape next to him and tugged it on the graphite sheet. Then he threw it into the trash can next to him. Then he tore a piece of tape and stuck it off. Throwing it into the trash can while watching, the latter raised his eyebrows, his brain full of incredible: "This MIT PhD in Physics doesn't even look at what is stuck on the tape? Is this black under the lamp?"

Not long after Zheng Jianguo’s thoughts flashed, with the help of Ulrika, who had obviously not done an experiment, the three of them got 983 angstroms of graphitic carbon film before lunch. The experimental class is considered complete. , As for the basic physics class scores this semester, you still need to wait for Thomas’s score to determine, but Zheng Jianguo can be sure that the graphene that everyone is looking for is stuck on the tape that was thrown into the trash can——

Looking at Zheng Jianguo driving away from MIT from a distance, Ulrika’s brown eyes did not see the slightest fluctuation, until she did not remember what she thought of, turned around and nodded at Celia, “Then I’ll go back to the professor, you guys. Your results will be notified by the school."

"Okay, go slowly."

Celia nodded and said, Ulrika turned and left, but when she returned to the college office to find Professor Thomas, she looked vigilantly back and forth, and she opened her mouth and said, "Thank you Professor Thomas, thank you Your support for the FBI—"

"Zheng is a good student and very smart, although he is a little taciturn, he should not be the kind of person you are looking for."

Thomas wore a typical Mediterranean hairstyle, and his bald forehead became brighter and brighter under the light of fluorescent lamps. Ulrika immediately smiled and said, "As you said, he is very smart, so I need to pay attention to him. MIT’s learning situation to avoid unnecessary trouble—"

"My basic physics courses are the most basic things, and no one told me that he was not allowed to take elective courses."

Thomas shook his head and said that he had a good impression of Zheng Jianguo during this period of time: "It seems a bit weird now, after all, he is the only Harvard medical student who has taken basic physics in these two years—"

"That's the case, let's meet again, I should go back."

Ulrika’s brown eyes flashed with a smile, and after leaving, she turned and left, and returned to the unit to fill out a detailed report and hand it in. Unexpectedly, more than a month after she was about to forget about it, her boss Charlie I found her: "Zheng Jianguo discovered the atomic-grade graphite layer—"

"How can this be?!"

Ulrika blurted out with a shocked face, then picked up what Charlie had turned to her, her brown eyes shrunk instantly: "Boston Regional? He posted the discovery to the daily newspaper-torn with tape?"

"Yes, what I want to ask you is, just use graphite tape to fold it in half and tear it a few times to get a two-dimensional material that scientists all over the world can't get?"

Charlie’s face was a bit dark, and it didn’t take long for him to recover from the effects of Katsana’s suicide. He thought that Ulrika had already dealt with this matter, but he did not expect that Zheng Jianguo, who had lowered his suspicion, would give him Looking for such a stall: "Does this possibility exist?"

"Tear the tape, um, if it is a symmetrical tear, you only need to tear one million layers 20 times, Fack, this guy is too smart—"

The brown eyes swept across the report, Ulrika’s shocked eyes gleamed, but when she looked up, she saw Charlie’s dark face, and she said, “We used to do experiments to tape off. The graphite dust was then thrown into the trash can. I never thought that the thickness of what I was looking for was thinner and smaller than graphite dust. He is now preparing to test this two-dimensional material. I want to go over—"

"What's the use of this two-dimensional material?"

Charlie’s black face has recovered a lot. Before entering the FBI, he studied financial management, and he couldn’t get along with basic physics. Now knowing that the goal is just to do a basic physics experiment, he has made new discoveries. His instinct tells him that this is not good news: "What can be done?"

"This, I don’t know, this is something that has never been discovered before. No one knows what can be done. Everyone is looking for it because of pure basic research. If I go there, it can help him confirm that this thing can doing what--"

Ulrika thought about it with a dull face, and then quickly said that Charlie looked at this doctor who is said to be a doctor of solid state physics, and nodded and said: "Well, I hope you will take out all this time. Focus on this matter. I don’t want to see reports like this after I get your report, know?"

"This—I see."

Thinking of the content of the report she submitted, Ulrika swallowed back with her throaty excuse. After all, she thought it was a bit too simple. Of course, if she was really like Zheng Jianguo in the newspaper. It's as simple as that.

Thinking of this, Ulrika, who left the office, understood why Zheng Jianguo would post this news in the daily newspaper. At this moment, he was afraid that he hadn't fully understood that the appearance of this material broke the physicists’ perception of this The theoretical cognition of materials is very likely to break the laws of thermodynamics-this subverts the theory of solid state physics (condensed matter physics)!

When Ulrika took the bus to Thomas' office at MIT, she got an expected answer: "Professor Thomas is leading the laboratory to study Zheng’s findings. They are now in the laboratory. , You need to get the approval of the school board if you want to go—"

"ok, I get it--"

Her pale complexion changed slightly, Ulrika remembered that she could recognize the impact of this discovery on solid-state physics, so how could MIT, the world's highest engineering institution, fail to understand the significance of this discovery? I am afraid that all the physicists from the school have run into this laboratory at this moment: "Zheng, are there too? It is Zheng Jianguo, Harvard Medical School——"

"Yes, he is also."

The assistant teacher in the office quickly nodded and said that Ulrika knew that she was not at a level enough when she cursed Syntactic in her heart. Now it is the right thing to find someone to authorize: "Well, can I use the phone?"

The call was quickly connected. Ulrika said about the problem encountered. Charlie's voice will ring when he is silent: "You are on standby."

"Ok!"

Ulrika quietly put down the microphone, originally thinking that there would be news soon, but didn't think about it until half an hour later, but the phone next to the office rang and was picked up by the assistant teacher, looked up at her and said: "Okay, you can pass, the laboratory on the 5th floor of Building 35."

"Thank you!"

Thinking of the experiment that seemed to be done in Building 36 last time, Ulrika did not hesitate to leave the office building and head straight for No. 36. When I was far away, I saw six or seven bright-headed professors gathered at the entrance. After she got closer, she heard a comment among these people: "The relationship between momentum and energy of single-atom layer graphite determines the mass effect of electrons and holes—"

"???"

Rao Ulrika got a PhD in solid-state physics. After hearing this sentence, she also found out that she would not understand it. Fortunately, she knew that some of these shameless people were probably academic leaders. Just as the wind came into the building, I didn’t expect that there were more people with bright foreheads: "Not to mention that carbon atoms have 4 valence electrons, and 3 of them form sp2 bonds, that is, each carbon atom contributes one in pz. Unbonded electrons on the orbit--"

"——The coordination number of carbon atoms has not been determined. The bond length between every two adjacent carbon atoms has to be measured, and the angle between the bond and the bond—"

"——Theoretical Young's Modulus——"

"——Carrier migration at room temperature——"

"——The electron carrier and the hole carrier——"

"——I don’t know how its conduction and valence band are in Dirac——"

"——Biological and oxidizing——"

"——Electrons under high magnetic field strength——"

Listening to all kinds of words and short spells coming from near or far, Ulrika tried to make herself silent and pressed the button at the elevator entrance. Soon the elevator car came down from the upper floor and opened. After a ding sound, the entire noise disappeared.

Feeling inexplicably, everyone’s eyes fell on the back and swallowed and entered the elevator car. Ulrika turned around and found that everyone looked at her with different expressions, and quickly pressed down on the fifth floor. Push the button and the elevator door closed and he breathed a sigh of relief: "Nobel Laureate Philip and Mr. Aken are here too—"

"Ding--"

As the elevator door opened, Ulrika went out. Someone in the transparent laboratory was bent over holding tape to stick it back and forth, and someone approached the laboratory door: "Hello, this laboratory today Not open to the outside world—"

"Well, I have authorization, Ulrika."

Glancing at more than half of the seven or eight people in the laboratory who were tearing tape, Ulrika veiled her identity to the visitor. The latter swept through the notebook in her hand and then retreated to the laboratory. At the door, he whispered to the man next to him, and he nodded his head: "What needs our cooperation?"

"No, I will make sure that Zheng will not be exposed to too sophisticated experiments."

Ulrika’s mouth said, a pair of brown eyes swept across the tightly wrapped experimenter in the laboratory, but the latter blinked and said, “Well, this time the atomic-grade graphite layer was discovered by Zheng. Said that he should not be exposed to too sophisticated experiments-do you intend to send him back to the Republic to carry out research in this field?

And as far as I know, the experiment he conducted with others last time was at his own expense. Later I learned that Zheng made a lot of money in the futures market, which is enough for him to complete basic research in any field, of course the biggest Maybe I think he will receive state-level funding when he returns. This should not be good news for you."

"Is it doing repeated tests inside?"

Ignoring the other party’s contempt for the department she represents, Ulrika looked at the actions of the people inside and said, the person who had spoken before continued to speak: "Yes, repeatable experiments are all scientific research. Basically, although his statement in the regional newspaper is very constructive and scientific, I feel that all physicists and scholars who read this report should be doing this repeated experiment. Of course, this refers to the Boston area. People who read the Boston Regional News and saw it--"

"That means that Zheng cannot be restricted from participating in cutting-edge experimental research at MIT?"

Ulrika swallowed her saliva. The purpose of her visit was to confirm Zheng Jianguo’s involvement in the atomic layer graphite structure, and to limit Zheng Jianguo’s research without attracting more attention. I heard this person who clearly understands research and her requirements said, I knew that this matter could not be solved by myself: "If you control him now—"

"This news has appeared in the Boston Regional News--"

The man shrugged and said that when he found Ulrika still looking at him, he smiled and said: "Then not only academia will value his discovery, but the whole world will notice your hands and feet— —"

"Are you kidding him?"

Ulrika quickly turned her head and looked at the man with a suspicious face. She said that she did not expect the latter to have a bright smile: "Zheng thinks he can finish MIT while studying at Harvard. Before you came, Professor Thomas and the Secretary of the Aurora School Department and Mr. Philip, who had left before, expressed their recognition of the study of the master's degree in basic physics. Therefore, it is normal for me to protect Zheng-he has now received letters of recommendation from three professors. , Will study with Professor Thomas with other master students in September."
