"Transparent gel...cloth?" Gu Xiguo widened his eyes and asked in surprise.

"Yes, it's the one with office stationery." Zhou Shuo gestured and gave a specific indication of his request.

"Does anyone have transparent tape?" Gu Xiguo secretly regretted that Zhou Shuo was really unreliable. I asked you what equipment you use for scientific experiments? Why do you want tape? Do you stick the two devices together?

"Puff-hahahaha, this is the first time I heard of using tape to do material experiments!" Finally, someone couldn't help but laughed.

After the first person was present, everyone in the laboratory laughed.

"Principal, where did you find the weird guy? You actually want to use tape to do experiments! It's just an insult to the civil sciences!" Although Professor Huang was a little awe of Gu Xigua, he was also angry in the face of Zhou Shuo's request.

Laboratory No. 1 is the best in the materials laboratory. Being able to be responsible for this laboratory can also show Professor Huang's academic level, and he is definitely not an ordinary person. However, such a very sacred place for him, now a person who wants to do experiments with tape is simply an insult.

"A laboratory of such a big one won't even have tape, right?" Zhou Shuo spread his hands and said helplessly.

"Give it!" A graduate student took a roll of transparent tape from the side and threw it to Zhou Shuo and shouted: "This is 3m tape, don't say that things are not good enough. I see how you use it to break through the world problems in the physics world!"

I have worked hard to study physics for more than ten years but can't do anything I have been studying for physics for decades. Could it be solved by a bundle of transparent tape? What a joke? This is a provocation to their professional ability! Everyone looked at Zhou Shuo angrily, waiting to see how he made a fool of himself, and then he must throw him out of the materials laboratory!

Gu Xigua also hesitated a little. Although Liu Haipeng was not a disciple who was particularly proud of, he was also a good person. He didn't think much about the person recommended by the director of the Provincial Science and Technology Commission. After all, he had been teaching for decades and had never seen any kind of genius students, and it was not impossible to solve world problems in his twenties.

But who knew that Zhou Shuo was so untuned that he actually said that he would use a transparent tape to test the two-dimensional material graphene. If this fails, where can he put his old face? Others would not make fun of Liu Haipeng and introduce Zhou Shuo to him. He would only say that he was not aware of people. People in their sixties care about this reputation?

"Graphite slices, you have to give me graphite slices, right?" Zhou Shuo didn't care about the eyes of these people. The invention of graphene was originally a very mythological thing.

Before graphene was successfully separated and prepared by Andrei Heim and Konstantin Novosholov in 2004, graphene was even considered to be just a non-existent idea. To say that these professors directly bombarded him without hearing about graphene. It was already very well-educated.

Before graphene was really successfully separated, who could think that the answer was really so simple. Just a bundle of glue can solve this seemingly unsolvable problem in the physics world?

Under Gu Xigua's urging, a graduate student reluctantly made a graphite slice. There was ready-made slice equipment in the laboratory, which was not troublesome to make.

Twenty years later, someone wrote a joke about graphene invention to pour dirty water on Chinese creativity. It is said that before Andrei Heim and Konstantin Novosholov invented the separation of graphene with tape, they asked a Chinese student to try to isolate the "thinest graphite flakes". This Chinese doctor worked with the most advanced polishing machine for three weeks before he got a ten-micron thick graphite spot. When he stared at his red eyes and made the result, Andrei Heim was still not satisfied.

As a result, the two of them were still not satisfied with the thinness of the graphite slices, so they had a sudden idea and had the idea of ​​using tape to reduce the thickness of the graphite slices.

In the joke, this has become evidence that Chinese people only follow the rules and have no creativity. Not to mention whether there are Chinese people in the invention of graphene, isn’t science a way to go all possible paths?

It's like a person only has enough to eat the tenth bun. Is it useful to say that only the tenth bun is useful? It doesn't matter whether the first nine eats or not? It is precisely because a research assistant has tried all the ways that the two scientists have been named.

In the development of science and technology, failure and success play an equally important role.

"For you." The graduate student placed the graphite slices in front of Zhou Shuo and looked at him coldly.

Zhou Shuo shrugged his shoulders, pulled the tape to stick it on the surface of the graphite slices, and then took the tape off the graphite slices, so he got a transparent tape with a layer of graphite sticking.

After he finished this step, the laboratory almost suddenly became quiet and immediately. The worst part of the audience was graduate students, doctoral students, and professors. You may not know much about graphene, but you are familiar with the characteristics of graphite. One of the characteristics of graphite is the layered structure, which once had a very weak connection with each other. This is also the reason why pencils can write. It is just the force of friction between graphite and paper, so many layers of graphite can be peeled off from the stone mill.

So if you use transparent tape to continuously peel off the number of layers of graphite slices, can you finally get a thin enough graphite material?

Thinking of this, everyone became eager to see. Even if they couldn’t get real graphene, being able to make a thin enough graphite layer is a very impressive result!

"Can you do me a favor?" Zhou Shuo was a little busy tearing the transparent tape, and accidentally couldn't find the beginning of the tape.

"I'll do it!"

"No, I'll do it."

"Ahem - I'll do it." Professor Huang glanced around and glared back at the doctoral students who were eager to try.

Just kidding, if there is any result, even if you stand next to tear the tape, you can fill in your name in the paper. Where is such a good job, what's the turn to do?

Tear-

Professor Huang squinted his eyes and touched it for a long time, finally found the beginning of the tape, and then teared it down quickly. Judging from the results, this may be the most educated tape in similar experiments. Serious experiments are all about the instructors who move their mouths and students break their legs, especially materials science experiments are often full of magnificent. How could the instructors tear the tape personally for the experiment?

The two of them just tore the tape and the tape. The transparent tape that was originally stained with a layer of graphite quickly became thinner under constant peeling conditions at a speed visible to the naked eye.

"Are you okay?" The graduate student behind him asked anxiously when he saw the graphite layer gradually becoming transparent.

"It's much worse." Zhou Shuo said calmly with his eyes fixed on the tape.

The simple repetitive labor made Professor Zhou Shuo and Professor Huang sweat. However, they were pretty good, and the people watching around were more anxious than them.

At this time, Gu Xigua could not tell that he was in his sixties at all. Just looking at his red face, it was believed that he was a middle-aged man in his forties. The professors, doctoral students around him were similar, and his heads filled Zhou Shuo's surroundings like sunflowers. Their eyes were as big as they were about to stand out, just to be closer to the experiment.

"Is it done?" Professor Huang asked nervously with his hands trembling.

His hand shaking was not related to his nervousness. If anyone had been tearing the tape for more than an hour on his hand, he would probably have to shake it even if he stopped. There was someone in the middle who wanted to replace him, but he didn't know that Professor Huang, who was usually a good-tempered person, was so excited that he wanted to scold him, as if he was not trying to help him, but rob his wife.

"It's almost done!" Zhou Shuo touched the sweat on his head. At this time, the shadow of graphite was almost no longer visible on the tape. The absorption rate of graphene to light was only 2.3%. If it was just a single layer or several layers of graphene, the human eye could not see it at all.

"Hurry, use the electron microscope to scan!" Gu Xiguo stared at his eyes and shouted at the top of his lungs.

The so-called scanning electron microscope is the abbreviation of scanning electron microscope. It can bombard the surface of a substance with a beam of high-energy incident electrons. Using the interaction between electrons and matter, it can obtain various physical and chemical properties of the sample being tested.

To detect the morphology, composition, crystal structure, electronic structure and other attributes of the substance, select different information detectors to obtain the microscopic content of the substance.

Of course, it was not Zhou Shuo's turn to do the operation of the electron microscope. A group of people installed the equipment in a slight manner and started the electron microscope. The results of the electron scanning soon appeared on the monitor.

"This is..." Gu Xigua looked at the monitor, pondered for a moment, turned around and looked at Professor Huang and said, "Old Huang, you are the authoritative authority in materials science at our Bohai University. You can draw a conclusion."

Professor Huang swallowed, came to the front of the monitor, and carefully observed the image obtained after the electronic scan.

"Hexagon, sp2 hybrid orbit. Oh my God, this is really graphene, only one layer of two-dimensional material!" Professor Huang shouted excitedly. The neatly honeycomb-like arrangement was like the most beautiful painting in his eyes, so beautiful that it makes people intoxicated.

"It's true, graphene actually exists!" Everyone surrounded the monitor and was amazed when they saw the scanned image.

"But this is unscientific. The existence of graphene conflicts with existing scientific theories!"
