Chapter 161 (1/2)
An hour later, Zheng Jianguo even operated the spectrometer and microscope three times. Brady was still holding the graphite sheet to punch the grinder. At this time, let alone him, even Celia felt something was wrong. She looked at him with curious blue eyes, and Ulrika came to the grinder: ”have you finished grinding?”
”Cough -”
Taking off his goggles and mask, Brady saw his hand holding the graphite sheet trembling slightly. Ulrika's brown eyes fell on his hand, flashed on her face and suddenly said, ”sorry, I got you the wrong graphite sheet. This is high-density graphite. I'll get you a piece of natural graphite. Here, that's it. You try?”
”Ah --”
Brady almost didn't spit out his old blood. He looked at Ulrika's innocent cheek like a little girl, turned his head and looked at Zheng Jianguo, who was talking to himself and Celia about the microscope. After turning back, he put on his goggles and mask, took the graphite sheet, blinked and said, ”this can't be high-density?”
”No, I just saw it. It must have been the wrong box for the last wave of experiments. You see, the luster of this piece of graphite is somewhat different from that of the previous one -”
When Ulrika finished the explanation with innocence on her face, Brady gulped down his saliva and pressed the graphite sheet against the grinder to make him work. But soon, with contact with the sand belt on the grinder, his heart of choice was put down. The previous piece had been polished for a long time without moving, and a large piece of graphite powder was grinded out as soon as it touched, The hanging heart relaxed a little. It didn't use much. The meeting saw Ulrika holding a thin blade next to him: ”cut it as thin as possible -”
Turning to look at Ulrika, Brady picked up a piece of tape next to her, pulled it and stuck it on the graphite sheet, threw it into the nearby trash can, then tore off a piece of tape and stuck it, and threw it into the trash can under Zheng Jianguo's gaze. The latter picked his eyebrows and was full of strange thoughts: ”the doctor of physics at MIT doesn't even see what's stuck on the tape? Is it black under the light? ”
Zheng Jianguo's idea flashed. With the help of Ulrika, who obviously didn't do an experiment, the three got 983 Amy of graphite carbon film before lunch. This experimental class was also completed. As for the score of basic physics this semester, it still needs to be determined by the score given by Thomas, but what Zheng Jianguo can be sure is, The graphene we were looking for was stuck to the tape thrown into the trash can——
Looking at Zheng Jianguo driving away from MIT from a distance, there was no fluctuation in Ulrika's brown eyes until she didn't know what to think of. She turned and nodded to Celia and said goodbye: ”then I'll go back to the professor. Your grades will be notified by the school at that time.”
”OK, you go slowly.”
Celia nodded and said that Ulrika turned and left, but when she returned to the college office to find Professor Thomas, she looked around with vigilance and opened her mouth. What she said was not the result: ”thank you, Professor Thomas, for your support to the FBI --”
”Zheng is a good student and very smart. Although he is a little silent, he should not be the kind of person you are looking for.”
Thomas wore a typical Mediterranean hairstyle, and his bare forehead became brighter and brighter under the sunlight. Ulrika immediately smiled and said, ”as you said, he is very smart, so we need to pay attention to his study at MIT to avoid unnecessary trouble --”
”My basic physics courses are the most basic things. No one told me that he was not allowed to take them.”
Thomas shook his head and said that he had a good impression of Zheng Jianguo during this period: ”it seems strange now. After all, he is the only Harvard Medical student who has taken basic physics in the past two years.”
”That's right. Let's see you again. I should go back.”
Ulrika's brown eyes flashed with a smile. After leaving, she turned away and returned to the unit to fill in the detailed report. Unexpectedly, more than months after she wanted to forget it, her immediate boss Charlie found her: ”Zheng Jianguo found the atomic graphite layer -”
”How is this possible?!”
Ulrika blurted out with a shocked face, then picked up what Charlie turned to in front of her, and her brown eyes narrowed in an instant: ”Boston Regional? He posted the discovery in the daily newspaper - torn with tape? ”
”Yes, what I want to ask you is that you can use the tape pasted with graphite to fold and tear it in half, and you can get two-dimensional materials that scientists all over the world can't get?”
Charlie's face was a little black. He didn't recover from cassana's suicide. He thought Ulrika had handled the matter, but he didn't expect Zheng Jianguo, who had reduced his suspicion, to find him such a stall: ”does this possibility exist?”
”Tear the tape, well, if it's symmetrical, it only takes 20 times to tear a million layers, Falk, this guy is too smart -”
Her brown eyes swept through the report at a glance. Ulrika's shocked eyes lit up. She just looked up and saw Charlie's black face. She said, ”we used to do experiments with tape to stick off the graphite dust, and then threw it into the trash can. We never thought that the thickness of what we were looking for was thinner than the graphite dust, He is now preparing to test this two-dimensional material. I want to go -- ”
”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. He can't get along with basic physics. Now he knows that the goal is to make a basic physics experiment and make a new discovery. His intuition tells him that this is not good news: ”what can we do?”
”Well, I don't know. This is something that no one has ever found before. No one knows what to do. Everyone is looking for it because of simple basic research. If I go, I can help him confirm what this thing can do -”
Ulrika thought for a while and said quickly. Charlie looked at the doctor's hand who was said to be in solid state physics and nodded and said, ”well, I hope you will spend all your energy on this matter this time. I don't want to see reports like this after I get your report, okay?”
”This -- I see.”
Thinking of the content of the report she handed in, Ulrika swallowed her explanation to her throat. In the final analysis, she thought it was a little too simple. Of course, if she was really as simple as Zheng Jianguo thought in the newspaper, it would be good.
With this in mind, Ulrika, who left the office, understood why Zheng Jianguo sent the news to the daily newspaper. At present, he may not fully understand that the emergence of this material has broken physicists' theoretical cognition of this material, and it is likely to break the law of thermodynamic fluctuation - which has subverted the theory of solid physics (Condensed Matter Physics)!
When Ulrika took a bus to Thomas' office at MIT, she got her expected reply: ”Professor Thomas is leading the laboratory to study Zheng's discovery. They are all in the laboratory now. If you want to go in the past, you need to get the approval of the school board -”
”Well, I see -”
Her white complexion changed slightly. Ulrika remembered that she could realize the impact of this discovery on solid-state physics. How could MIT, the world's highest Engineering University, not understand the significance of this discovery? I'm afraid that physicists all over the school ran to this laboratory now: ”Zheng, is it also in there? Zheng Jianguo, Harvard Medical School -- ”
