An hour later, Zheng Jianguo even operated the spectrometer and microscope three times, Brady was still pinching the graphite sheet and punching the grinder, not to mention him at this time, even Celia felt a little wrong, and looked at him with a pair of curious blue eyes, and Ulrika also came to the grinder: "Is the grinding done?"

"Ahem—"

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 and suddenly said: "I'm sorry, I got you the wrong graphite sheet, this is high-density graphite, I'll get you a piece of natural graphite, oh, that's it, you try?"

"Ahh

Brady almost didn't squirt out a mouthful of old blood, looked at Ulrika's innocent cheeks like a little girl, turned his head and looked at Zheng Jianguo, who was talking to Celia with his back to the microscope, and after turning around, he put on goggles and a mask and took the graphite sheet, blinked and said, "This, it won't be high-density, right?"

"This won't be, I just watched, it must have been misplaced in the box from the last wave of experiments, you see that the luster of this graphite is a little different from the previous one-"

Forced to the cheerfulness of his throat to explain, Ulrika finished speaking with an innocent face, Brady swallowed his saliva, pinched the graphite sheet and rushed to the grinder, but soon with the contact with the abrasive belt on the grinder, his choice of heart was also put down, the previous piece of grinding for a long time did not move, this piece of this piece grinded out a large piece of graphite powder as soon as it was touched, and the hanging heart was relaxed a little, and it didn't take long to see Ullica holding a thin blade next to him: "Cut as thin as possible-"

Turning his head to look at Ulrika, Brady picked up the tape next to him and pulled a piece of it and glued it to the graphite sheet, and threw it into the trash can next to him, and then tore off a piece of tape and glued it off, and threw it into the trash can under Zheng Jianguo's gaze, the latter raised his eyebrows, full of incredulity: "This MIT doctor of physics doesn't look at what is stuck on the tape? This is dark under the lamp?"

Not long after Zheng Jianguo's thoughts flashed, with the help of Ulrika, who obviously didn't do an experiment, the three of them got nine hundred and eighty-three emittries of graphite carbon film before lunch, and this experimental class was also completed, as for the results of this semester's basic physics class, it still needs to wait for the score given by Thomas to determine, but what Zheng Jianguo can be sure of is that the graphene that everyone is looking for is stuck to the tape that was thrown into the trash-

Looking at Zheng Jianguo driving away from MIT from afar, Ulrika's brown eyes did not fluctuate at all, until she didn't know what to remember, turned around and nodded at Celia and said goodbye: "Then I'll go back to the professor, and your results will be notified to you by the school then." ”

"Okay, you go slowly. ”

Celia nodded and said, Ulrica turned and left, but when she returned to the college office to find Professor Thomas, she looked back and forth vigilantly, and opened her mouth to say not grades: "Thank you, Professor Thomas, for your support of the FBI-"

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

With a typical Mediterranean hairstyle and his bare head getting brighter and brighter under the fluorescent lamp, Ullica immediately smiled and said, "As you said, he is very smart, so he needs to pay attention to his studies at MIT to avoid causing unnecessary trouble—"

"My basic physics classes were all the most basic things, and no one told me that he wasn't allowed to take them. ”

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

"That's right, then let's meet again, I should go back. ”

Ulrika's brown eyes flashed with a smile, and after saying goodbye, she turned to leave, returned to the unit and filled out the detailed report and handed it in, but she didn't expect that just a few months after she was about to forget about it, her boss Charlie found her: "Zheng Jianguo has discovered an atomic-level graphite layer——"

"How is this possible?!"

Ullica blurted out with a shocked face, and then picked up what Charlie had turned in front of her, her brown eyes shrinking instantly: "Boston Area Newspaper?

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

Charlie's face was a little dark, he had only recovered from the effects of Kashana's suicide for a long time, he originally thought that Ullica had already dealt with this matter, but he didn't expect that Zheng Jianguo, who had lowered his suspicion, found him such a mess again: "Does this possibility exist?"

"Tear the tape, well, if it's symmetrical, a million layers can be torn 20 times, Fack, this guy is so smart-"

Brown eyes swept over the report, Ulrica's shocked eyes lit up, but when she raised her head and saw Charlie's black face, she said: "We used to do experiments to glue off graphite dust with tape, and then throw it into the trash, never thought that the thickness of what we were looking for was thinner or smaller than graphite dust, and 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, he studied financial management before entering the FBI, and he can't get along with basic physics, and now he learns that the target is just a basic physics experiment and has a new discovery, his intuition tells him that this is not good news: "What can be done?"

"Well, I don't know, it's something no one has ever found before, no one knows what to do, and everyone is looking for it because it's just basic research, and if I go, I can help him confirm what this thing can do—"

Ulrica thought for a moment with a dull face and said quickly, Charlie looked at this doctor who is said to be solid state physics, and nodded: "Okay, I hope you will devote all your energy to this matter this time, I don't want to see reports like this after getting your report, you know?"

"This- I see. ”

Thinking of the content of the report she handed in, Ullica swallowed back the justification that reached her throat, this kind of thing is still a little too simple for herself in the end, of course, if she is really as simple as Zheng Jianguo in the newspaper thinks, it would be fine.

Thinking so, Ulrika, who left the office, also understood why Zheng Jianguo posted the news to the daily newspaper, and at this time he was afraid that he had not yet fully understood that the appearance of this material broke the theoretical understanding of physicists about this material, and it was very likely to break the law of thermodynamic fluctuations - this subverted the theory of solid state physics (condensed matter physics)!

When Ulrika took the bus to Thomas's office at MIT, she received a reply that she expected: "Professor Thomas is leading the lab to study Zheng's discovery, and they are all in the lab now, and if you want to go, you need to get approval from the school board—"

"Okay, I see—"

Her fair face changed slightly, and Ulrica remembered that she could realize the impact of this discovery on solid state physics, so how could MIT, as the world's highest engineering university, not understand the significance of this discovery, I am afraid that at this time, the physicists of the whole school will run to this laboratory: "Zheng, is it also in there? It's Zheng Jianguo, Harvard Medical School-"

"Yes, he's there, too. ”

The assistant teacher in the office nodded quickly, and Ulrica scolded in her heart that she knew that her level was not enough, and now it was the right thing to find someone to authorize: "That, can I use the phone?"

The call was quickly connected, Ulrika said the problem encountered, and Charlie's voice was silent and would ring: "You stand by now." ”

"Okay!"

Ullica silently put down the microphone, originally thinking that there would be news soon, but she didn't expect to come over until half an hour later, but the phone next to the office rang and was answered by the teaching assistant, looked up at her and said, "Okay, you can go over, the laboratory on the 5th floor of Building 35." ”

"Thank you!"

Remembering that the last time it seemed to be an experiment in Building 36, Ulrica did not hesitate to leave the office building and go straight to No. 36, and when she was far away, she saw that there were already six or seven professors with shiny brains gathered at the entrance, and when she got closer, she heard a discussion among these people: "The nature of the momentum and energy relationship between single-atom graphite determines the mass effect between electrons and holes——"

“？？？”

Rao is Ulrika got a doctorate in solid state physics, and after hearing this sentence, she found that she would also understand it, but fortunately, she knew that there were likely to be academic bigwigs among these unattractive people, so she directly entered the building as a deaf ear, but she didn't expect that there were more people with bright brains inside: "Not to mention that carbon atoms have 4 valence electrons, 3 of which form sp2 bonds, that is, each carbon atom contributes an unbonded electron located in the pz orbital——"

"--The coordination number of the carbon atom is not determined, and the bond length between each two adjacent carbon atoms has to be measured, and the angle between the bonds is these -- "

"—Theoretical Young's modulus——"

"—Carrier migration at room temperature—"

"—Electron carriers and hole carriers—"

"-I don't know what happened to its conduction and valence band in Dirac-"

"-Biological and oxidative-"

"—Electrons at high magnetic field strengths—"

Listening to all kinds of words and spellings coming from near and far, Ullica tried her best to get to the elevator without making any sound and pressed the button, and soon the elevator car came down from the stairs and opened, and the whole noise disappeared after a clanging sound.

Inexplicably, everyone's eyes fell on the back of the swallow and spitted into the elevator car, Ulrika turned around and found that everyone was looking at her with different expressions on their faces, so she quickly pressed the button on the fifth floor, and only then did she breathe a sigh of relief after the elevator door closed: "Nobel laureates Philip and Mr. Akon are also here-"

"Ding—"

As the elevator door opened, Ullica went out, and saw someone in the transparent laboratory bending over with adhesive tape to stick it back, and someone leaned over to the door of the laboratory: "Hello, this laboratory is not open to the public today-"

"Well, I'm authorized, Ulrika. ”

Glancing at the seven or eight people in the laboratory, more than half of them were tearing the tape, Ullica vaguely identified herself to the person who came, and the latter swept over the small notebook in her hand, and then retreated to the door of the laboratory and muttered a few words to the man next to her, and saw that this person nodded: "What do you need our cooperation?"

"No, I'm here to make sure Zheng doesn't come into contact with too cutting-edge experiments. ”

Ulrika spoke, a pair of brown eyes swept over the tightly wrapped experimenters in the laboratory, but the latter blinked and said: "This, this atomic-level graphite layer was discovered by Zheng, if you want to say that he will not be exposed to too advanced experiments-you plan to let him return to the Republic to carry out research in this field?"

And as far as I know, the last time he and others carried out the experiment was at his own expense, I later 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 possibility is that I think he will receive national funding when he goes back, which should not be good news for you. ”

"It's a repeat test in there?"

Ignoring the contempt for the department she represented, Ulrika looked at the actions of the people inside, and the person who spoke before continued to speak: "Yes, reproducible experiments are the basis of all scientific research, and 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 means that people in the Boston area who have subscribed to the Boston area newspaper and still see it-"

"That means you can't limit Zheng's participation in cutting-edge research at MIT?"

Ulrica swallowed, the purpose of her coming was to confirm the degree of Zheng Jianguo's involvement in the atomic-layer graphite structure, and secondly, to limit the content of Zheng Jianguo's research without attracting more people's attention.

"This news has been in the Boston Area Newspaper—"

The man shrugged his shoulders and said, seeing that Ullica was still looking at him, he smiled and said, "Then it's not just the academic community that will pay attention to his discovery, I'm afraid the whole world will notice what you are doing—"

"You're protecting him?"

Ulrika quickly turned her head to look at the man and said with a suspicious face, but she didn't expect a bright smile to appear on the latter's face: "Zheng thinks that he can complete his master's degree in basic physics at MIT while studying for his M.D. at Harvard, and Professor Thomas and the secretary of the Aurora school department and Mr. Philip, who left earlier, expressed their approval, so it is normal for me to protect Zheng- He now has letters of recommendation from three professors and will be studying with Professor Thomas and other master's students in September. ”
