Chapter 38 The experiment is completed (seeking for further reading)
The autistic man has finally completed the parameter settings, adjusted the lens and light source, and can start the experiment.
Zhang Wei put the graphene sample he had made into the sample box, and then quietly waited for the machine to give out the data.
After a while, a photo of the structure of a hexagonal honeycomb lattice appeared on the monitor, which is exactly what graphene looks like.
Looking at this photo, the autistic man initially thought his face was expressionless, but when he saw the thickness shown, his expression suddenly changed.
"Thickness less than one nanometer, two-dimensional structure! What is this thing?" the autistic man asked fiercely.
“This is the first time I have seen an autistic person with such a strong desire for knowledge!”
Zhang Wei feels there is no need to hide it from an autistic person. After all, he is willing to take the risk of being expelled. Come and help yourself with the experiment, these are real brothers, the kind where you have to pay extra when you kill.
So Zhang Wei then introduced: "Didn't Professor Wu ask you to use a polishing machine to grind graphite as thin as you can? This is the final sample he wants, a single-layer graphite film, that is, Graphene!”
“This thing is graphene!” The autistic man looked at the photos on the monitor carefully, as if he were an artist admiring a great work of art.
Zhang Wei could feel that in the eyes of the autistic person, there was only the novelty of a child discovering a new toy, but there was no trace of greed.
“This guy will definitely become a pure scientist in the future!” Zhang Wei sighed in his heart.
The high-end transmission electron microscope is indeed several floors behind the basic scanning electron microscope Zhang Wei bought himself.
Not only is the magnification larger, the displayed pictures are clearer, but also some data that was not available before are also displayed.
Zhang Wei took out two USB flash drives and handed them to the autistic man.
"Help me copy all the data to these two USB flash drives! One copy of each USB flash drive."
"How much memory is there? There are pictures of these data." The autistic man asked.
“Don’t worry, 64 MB is definitely enough!” Zhang Wei replied.
You read that right, it is 64 MB, not 64G, but even this 64 MB USB flash drive cost more than 200 yuan at the time.
With the nanoscale transmission electron microscope, the progress of the experiment was much faster. By dawn, Zhang Wei had already obtained enough data.
If data analysis still needs to be done, there is a high probability that it will not be so fast, but Zhang Wei only needs to do data recording and does not need to do data analysis.
Because in the paper "Electric Field Effect of Atomicly Thin Carbon Films", the conclusion has been written, and this conclusion must be correct, otherwise it would not have been published.
So Zhang Wei only needs to fill in his own data, which greatly speeds up the progress of the experiment.
In the early morning, the two of them stretched at the same time and then turned off the device.
“I’m exhausted, let’s go back to the dormitory first! Take a nap first, and then go drink beer when you wake up!” Zhang Wei said with a smile.
When he heard about drinking beer, a gleam of light suddenly appeared in the tired eyes of the autistic man.
"By the way, have you deleted the experimental data on the computer?" Zhang Wei asked.
"Deleted, but only superficially. It is very simple to recover the data, unless the hard drive is smashed." The autistic man replied.
"That's not necessary. You can't damage public property. As long as you don't leave any traces, so as not to be discovered. I don't think anyone will restore the hard drive if they have nothing to do." Zhang Wei said.
Using this kind of high-end equipment to conduct experiments will inevitably leave relevant records and a series of experimental data.
If the seniors come back after the Spring Festival and open the equipment and see a bunch of unfamiliar data, even an idiot can guess that someone has used this electron microscope.
Looking at the time when the above data was generated, we immediately knew that someone secretly conducted experiments during the holidays. If you are a senior brother with a higher level, you might be able to guess what Zhang Wei is doing if you look at the experimental data carefully.
So the experimental data must be deleted to avoid leaving traces and being discovered by others.
But this kind of deletion is at best an operation similar to emptying the Recycle Bin. Any graduate student from the computer department can easily recover the data.
Unless you smash and burn the hard drive in your computer, it's really a one-and-done solution.
Zhang Wei obviously cannot do this. If you sneak in secretly to do experiments, it is just a violation of school rules, and at most you will be expelled from Tsinghua University.
But if you smash the hard drive, it is intentional vandalism. The price of this transmission electron microscope starts at tens of millions. According to the value of the case, it can be punished!
The autistic man hesitated for a moment, then said; "It should still be discovered."
"Why do you say that?" Zhang Wei asked.
"Because of the parameters, the machine has just been maintained and there are no parameters. The parameters I reset must be different from the original ones. I don't know what parameters the person who originally used this equipment set, so they can only follow mine."
“Can it be restored to the initialized parameters?” Zhang Wei asked immediately.
The autistic man shook his head: "Then the manufacturer will send technicians, but I can't do it!"
"This is a troublesome thing!" Zhang Wei frowned slightly.
When using this high-end experimental equipment, you must adjust the corresponding parameters. Parameters are not fixed. The new parameters set by autistic people are definitely different from the parameters that Senior Brother Yang and the others usually use.
So when Senior Brother Yang comes back from winter vacation, once he uses this transmission electron microscope, he will immediately find that the parameters are different, and the secret will most likely be exposed by then.
"It's okay. Anyway, this machine has just been maintained and the parameters don't exist. After school starts, the parameters will have to be reset. Maybe it won't arouse others' suspicion." Zhang Wei comforted.
The autistic person responded: "Science is very rigorous!"
Zhang Wei instantly understood what the autistic person meant. Science is very rigorous. In scientific research, one is one, and two That’s two. There is no word “maybe” in the dictionary of scientists!
"In other words, just because of this parameter, we will be discovered sooner or later?" Zhang Wei took a deep breath, calmed down, and then said: "It doesn't matter, you will blame the matter on me when the time comes. It’s the same old saying, I got you drunk and tricked you.”
"It's not necessary, I don't have to speak." The autistic man said.
"That's right. Anyway, you have autism. When the time comes, you don't have to find a reason at all, just say nothing."
Zhang Wei once again envied autistic people. When encountering difficulties, he can just pretend to be mute, and others really can't do anything to him. Even if you are Guo Degang and you are full of mouths, you can't argue with an autistic person!
At this moment, Zhang Wei suddenly discovered that autistic people know how to use their own advantages. It turns out that he is the real sober person in the world!
The autistic person then reminded: "Actually, you can say that this is burned white phosphorus. The burned white phosphorus has a six-membered ring structure, which is very similar to graphene."
< br>
"Six-membered ring, it's really possible to get through it!" Zhang Wei nodded with sudden realization.
Graphene is a hexagonal honeycomb structure. The biggest thing in common between the hexagonal honeycomb and the six-membered ring structure is that each atom is connected to three other atoms.
"Chen Ming, you have helped me a lot again!"
"Add a bottle of beer?" the autistic man asked tentatively.
“Buy you a box!”
I still have to ask you to continue to help me catch up on the reading. If you plan to keep reading, please find the latest chapter and click on it to scroll to the last page. With Qidian’s mechanism, whether you can get recommendations before it is put on the shelves depends on whether you follow it up. In order to get the next round of recommendations, I have changed the title of the book. I hope all the book friends will support me. Thank you all.
