With the thought of distant people, Zheng Jianguo read all the remaining letters and replied, confirming that Blanco's Rockefeller Fund did not know when there would be news, so the most involved energy was the laboratory of Qi Provincial Medical College, fortunately, there was Serena on Hong Kong Island at this time to help share this part, and the rest of his energy was devoted to graphene research and tutoring in basic physics.

I don't know whether it was because Thomas taught Zheng Jianguo according to his aptitude, or because Kou Yang's murmuring letter touched the IQ switch, and then after many months of research and study, just before Harvard Medical School and MIT entered the opening season in August 1979, the experimental team headed by Professor Thomas and supplemented by Zheng Jianguo finally came up with results.

It is found that the theoretical Young's modulus of graphene is 1.0TPa, and the inherent tensile strength is 130GPa, even if the reduced graphene modified by hydrogen plasma also has very good strength, with an average modulus of 0.25TPa, and the graphite paper made from this will be extremely strong and strong.

Just as Zheng Jianguo was applauding happily with the others, Thomas, who had reconfirmed the results of the repeated test, pointed to him and said: "Zheng, since you have more experience in writing high-end papers, this paper on the mechanical properties of graphene is written by you, and if you don't understand, you can ask others in the laboratory——"

"Thank you, Professor Thomas. ”

Zheng Jianguo's face showed joy after he was slightly stunned, a pair of dark eyes swept the professor's glowing head, and suddenly seemed to be back in front of Ye Minde when he was in Qi Provincial Medical College, only thinking that Thomas was looking at the many papers he sent to the "Lancet" when he arranged for him to write, a figure suddenly ran in outside the transparent glass window of the laboratory, and his dark face was full of excitement with both hands holding the magazine and slapping it on the glass, Lawrence, who was not far away, widened his eyes and looked at it, and then turned around with a face full of surprise: "Zheng, it's " Science》！”

"It's on the cover!"The miracle of tape tearing out, the discovery of atomic-scale graphite layer"!zhengjianguo!!"

When Wallace on the other side called out, Zheng Jianguo suddenly turned his head to look at Professor Thomas with a surprised face, and the latter said with a gentle smile on his face: "Congratulations, Zheng, presumably other professors in the Department of Physics will no longer prevent you from obtaining a master's degree with this thesis, of course, you are not the first seventeen-year-old master's degree in the academy——"

"Whoa—"

Bursting applause, Zheng Jianguo found that his eyes were hot, his vision was blurred, and he said with a gaffe: "This, this, this is a master's degree?"

"Congratulations, Zheng!"

"Congratulations, Zheng Jianguo!"

"Congratulations—"

Seeing that the others surrounded Zheng Jianguo and began to say hello, the gentle smile on Thomas's face turned into a bright one, and he said: "This is already a bit of a low salary, and it is not too much to give a Ph.D. to a cover paper of Science in other schools, but who made us MIT, well, Professor Fisher should know what you found——"

"Professor Fisher—"

Zheng Jianguo had a wry smile on his face, he had also inquired when he was taking a major in basic physics, after all, as a medical student at Harvard Medical School, it was impossible for him not to know that Harvard University also had a physics department and basic physics electives.

It's just that the address of Harvard University is a little far enough to pass by MIT twice as far as medical school, so it will be out of Boston to Cambridge, the exact location is in the suburbs of Cambridge, and he didn't have a car at that time.

Professor Fisher is a full professor of solid-state physics at Harvard University and a teacher of Zheng Jianguo's elective basic physics course.

"Don't think about it now, do you want to get a Ph.D.? Then let's write our research into a thesis - the mechanical properties of atomic-scale graphite layers!"

The smile on Thomas's face became brighter and brighter, and after finishing speaking, he turned around and changed his clothes and left, Zheng Jianguo also understood why he was able to enter the school so quickly at that time, Harvard University is one of the Ivies, and MIT is not famous for the development of the World Wide Web and computers at this time, and the major is still centered on engineering, thinking about the scenery of graphene in forty years, it also understands that a master's degree certificate is too small-

"We should buy some sticky tape—"

When Zheng Jianguo picked up the pen and was about to start writing, Lawrence's voice came from next to him, followed by Ulrika's: "Yes, although this is simple, but the scrap rate is too high, Zheng, do you have any good suggestions?"

"Hmm-"

Before writing the beginning, Zheng Jianguo turned his head to look at this sister, shook his head and said: "I feel that it is better to let the Department of Chemistry study how to increase the viscosity of the tape, so that they can also apply for a patent for this tape, what do you think?"

"That's—that's all. ”

Ulrika's brown eyes blinked, and two crow's feet appeared at the corners of her eyes, "Everyone, then let's celebrate at noon?"

"Yes, to celebrate, Zheng, we're not going to the Chinese restaurant this time — oh, you're only 17. ”

After Lawrence asked himself excitedly, he remembered that he was not old enough to enter the bar, and Ulrika next to him said, "We can buy some, but who has their own place to live?"

Lawrence looked at Wallace, shook his head, and said, "We're all in the dorm—"

Lanstrow and Colwyn opened their mouths together, "As if we weren't-"

"Why don't you go to my place. ”

Zheng Jianguo turned his head and looked at a few poor students, so he smiled and said: "But it's a classroom dormitory over there, you can bring wine and buy some wine, but I can't drink it, and don't bring prohibited things over, Da Ma and Hi Luo Yin can't do it, I will call the police when I see it——"

"Zheng, none of us are going to touch those things, you know, we don't even have enough for our own living expenses. ”

Lanstrours's height of 1.9 meters is the most obvious among several people, unlike others who only show their eyes after changing into experimental clothes, and when they heard that they could go to Zheng Jianguo's residence, they were obviously happy: "I heard that you still have games that have not been released there." ”

"Alright, you guys, um, to celebrate the results of our experiments, and to celebrate that I also have a Science paper, I'm going to invite you to play with me today, but you'll need to run your own errands for the things you buy. ”

Zheng Jianguo saw that everyone was so excited, and he also knew that the experiment during this time was too boring, and several people began to tear the tape and stick graphite since they entered the laboratory, and this sticking was more than a month, and he naturally didn't know that in the original history, the big guy who tore the tape relied on the tape he invented.

And Zheng Jianguo's previous repeated experiments wasted so much energy is also the reason, the lack of adhesive tape will cause the peeling effect to deteriorate, fortunately, it is only worse than nothing, and fortunately, his goal is only less than ten layers of graphene, not the original history of single-layer graphene, so the graduate students led by Ullica tore for a month and a half.

"I'm sorry about that—"

Ullica still maintained her previous attitude as a teaching assistant, but she was deflated by the excitement of the few people next to her, but Zheng Jianguo didn't take it to heart, and said with a smile on his face: "I should thank everyone for helping me during this time, without your response, my grades would not have improved so quickly——"

"Alright then, Zheng, thank you. ”

Ullica agreed on behalf of everyone, and Lanstrlo next to him immediately raised his big hand: "Yay~"

"Zheng, if you come out with a Ph.D. in solid-state physics, then you will be a double Ph.D. ”

Lawrence came to Zheng Jianguo's side with a happy expression, looked at the paper he wrote and said with a smile, and the latter smiled: "This can't be achieved in the short term, according to my study plan for medical school, it will take at least 3 years to pass the USMLE STPE1 and USMLE STEP2 and CSA exams for physician qualifications, but it is better than physics needs to be derived, and you can memorize by rote——"

"Medical school graduates are all doctors, and there is no master's degree, but Zheng, you can now say that you have a master's degree in physics-"

Wallace leaned against the table next to him as he spoke, but Ulrica said, "Okay, let's be quiet and let Zheng write the paper, don't you two do a repeat experiment?"

Wallace and Lawrence lowered their voices in unison, Zheng Jianguo could concentrate on writing, the book next to him recorded the data obtained in a month and a half, and the test process was written and added in accordance with the paper's formula, and it was written in less than half an hour, but when he wanted to record the first author after writing, he stopped his pen, and Ullika's voice came from the side: "Zheng, the rest can be considered by Professor Thomas-"

This time, Zheng Jianguo participated in the whole experiment for a month and a half, and the participants also included the laboratory at this time, as well as other people who began to gather to increase the number of graphene samples, so even if there was no Ulrika's advice, he would not list people in a big way: "Okay, let's pack up and go." ”

The use and cleaning of the laboratory belongs to who is responsible for it, on the one hand, it helps to develop good habits among students, and on the other hand, it deepens the implementation of management regulations, Zheng Jianguo put away his things after speaking, and he was not idle to the front of the cleaning table, the used substrate in front was still washing in the humming ultrasonic machine, and Ulrika picked up the vacuum cleaner and began to clean: "Zheng, I heard that minors in your family can drink?"

"Yes, some boys in the 14th Five-Year Plan will be asked by their fathers and grandfathers to taste it, of course, only to taste, and there are restrictions on what they can actually drink. ”

Zheng Jianguo didn't expect her to talk about this issue, of course, for the United States' blanket ban on alcohol, he also had a personal understanding after such a long time, and said with a smile: "But I won't have so many guns and vehicles at home, alcohol will promote people's blood circulation and speed up people's spirits, and it is easy to play a catalytic role in some things, such as the use of guns in quarrels-

And if there is no gun, the two of them will at most greet each other with their fists, so that there will be no too serious consequences, of course, we all know that fists can also kill people, such as through the skull, neck and heart, so for this requirement I am not because of the law to obey it, but because I think so, alcohol should be in moderation. ”

Ulrika obviously didn't expect Zheng Jianguo to say such a thing, her brown eyes looked at him with surprise, and she nodded slowly and said, "Maybe this is the cultural difference-"

After taking out the substrates in the ultrasound machine and putting them away, Zheng Jianguo looked at everyone and went to the door to change their clothes, and greeted the tall Lanstrow who came out and said, "Big man, please go and run down to see if you buy something to go to me-"

Seeing Zheng Jianguo take out two green knives from his wallet, Lanstrow turned his head to look at Wallace and raised his eyebrows: "yes, Zheng is going to invite us to a big dinner, then you go over first, Wallace Lawrence and I will go and buy it-"

"This money is not enough for a big meal, and when this paper is published, I will invite you to a big meal~"

Seeing that Lanstelo took the money, Zheng Jianguo smiled and said his address again and stuffed the wallet into his pocket, he now has no more money and no less, there are two hundred and forty-nine dollars and ninety-nine cents, in order to avoid being robbed and the family will not be able to rob it.

"Then let's go first~"

Lanstrow raised his chin at Lawrence and Wallace, and the three of them left with a smile, and as Ulrika changed her clothes and came out, Zheng Jianguo said, "I still have to send a paper to the professor, you wait for me next to the car first." ”

After more than a month of getting along, Ullika's small team of graduate students is familiar with each other, of course, as the only one in the small team to participate as a teaching assistant, she is also the only woman, turned her head to look at Colwin and Bodie who changed their clothes and locked the door, and nodded in response.

Thomas's office was on the third floor, and Zheng Jianguo didn't see him open his mouth after delivering the paper, so he said goodbye and left to drive Ullica and the three back to the dormitory.

Zheng Jianguo's eyes shrank and turned his head to look at the three of them, made a silent gesture and lay on the door, Ulrika next to him took a step back with a slightly changed face, and his right hand drooped and opened, Zheng Jianguo had already inserted the key and clicked it open, and when he saw that the room was empty, Colwin next to him said, "What, there are other people in this room?"

"No, I'm living here by myself. ”

Zheng Jianguo looked left and right at the situation in the room, and said to the three people with suspicious faces: "When I left, I made a mark on the crack of the door, that is, the position of the hinge, and the previous mark was gone——"

"Do you want to call the police?"

The brown eyes swept the hinge on the door in a miniature, and Ulrica asked with curiosity on her face, and saw Zheng Jianguo enter the house and said, "No, except for a valuable body armor at home, everything else is worthless-"
