Chinese entertainment for engineering students

Wang Xu's appointment was originally scheduled for a few days later, but something went wrong in preparing the reservation materials today, so Wang Xu's appointment was moved forward. As a result, Professor Duan and Senior Brother Zhang stayed up all night yesterday to determine the experimental procedures.

Professor Duan went back to sleep for a while in the middle of the night. Senior Brother Zhang didn't sleep at all. Wang Xu didn't say anything. After all, this project was no longer just his own. Both Professor Duan and Senior Brother Zhang would gain huge benefits from it. Absolutely no loss in accommodation.

But he was sure, Professor Duan and the others didn't know. They stay up late just because of responsibility and habit. It can be seen that their academic attitude is quite serious.

Scanning and observation of an electron microscope is not complicated. Just turn on the computer, fix the sample, fix the point, light, take pictures, computer process, harvest the pictures, analyze the pictures, that's it.

Later generations of electron microscopes can directly produce pictures in real time, but the current ones are not able to do so. They need to wait for a short period of time, and it also takes some time to adjust the electronic brightness and so on. It is quite troublesome to adjust various parameters, so it can only be done within a day. Make enough points quickly.

As for the analysis, I will analyze it slowly after I get it back. Professor Duan handed over this work directly to Senior Brother Zhang. The signature of the second work requires contribution. Wang Xu has already taken the lead. It is better to let Senior Brother Zhang do the chores.

Wang Xu had no objection and was happy to be at ease. There are hundreds of pictures, and I can only observe, analyze, and calculate the data bit by bit on a small monitor. I feel tired just thinking about it. This can't be done in a day or two. If you have a professional to help you, why not do it.

As for sharing the honors with others, Wang Xu disagreed. What's the big deal? After traveling through so many worlds, apart from your own abilities, what else can you take away?

Having more people to share the burden will only add more help to your own path, rather than hinder it. Eating alone is the easiest thing to hate. If others don't know this kind of distributed credit, how can insiders not know it? It's clear who is leading the matter.

As for Professor Duan, I still count on him for various subsequent studies on graphene. Could it be that Wang Xu just stuck in this field and failed to develop. Wang Xu is responsible for breaking the stick, and there must be a few people behind him to clean it up. Well, Professor Duan, the corn picking tool man is online.

After studying scanning electron microscopy for a day, Wang Xu left early because he had to go to work. I lost points for a month when I went to Xiangjiang, so I have to make up for them slowly. So after returning to the imperial capital, he started going to the market every day regardless of rain or shine.

"102 Wang Xu phone number"

Just on the afternoon of the third day, Wang Xu, who was preparing to go back to the courtyard to clean up the house and welcome Wang Fei's arrival, was yelled by the dormitory uncle to answer the phone.

"Wang Xu, you found it, we really found it, you are right." The call was from Professor Duan. His voice was trembling, and you could tell that he was very excited.

"Well, it's good that I found it. I was thinking about it." Wang Xu's voice was also a little excited. After all, he was not sure whether it could really be done. The high probability does not mean that it will be found. There are still 10 heads left after tossing a coin. Time.

"Why are you so calm? You don't know what this discovery means." Professor Duan seemed to be shocked by Wang Xu's dull tone.

"Two-dimensional materials have been confirmed for the first time in the world. It's a great achievement. I'm very excited." Wang Xu said flatly.

"You are so excited." Professor Duan complained unbearably.

"Are you from Yizhou?" Wang Xu felt that he must also be from Yizhou, as Hammer is their dialect there.

"I am, how do you know?" Professor Duan's excitement was completely interrupted, and even the topic was distorted.

"Only Yizhou people like to use hammers." Wang Xu explained calmly. In fact, he was also very excited. After all, there is a big difference between being able to find it and finding it. But after all, it's not as exciting as the kind of miracle that happens when you don't know and discover.

"Why is your focus so strange?" Professor Duan also calmed down. He couldn't understand this student. He was full of passion at one moment and as calm as water at another.

"Well, is it strange? My courtyard has hosted a band from Yizhou for a long time." Wang Xu explained.

"Yizhou band, rock band?" Professor Duan was unknowingly led to a completely distorted topic, and he didn't know where it went.

"Well, rock band, I can invite you to see them when they perform." Wang Xu invited enthusiastically.

"Okay, okay, eh, no, what did I want to inform you just now, Hammer." Professor Duan was completely led astray, suddenly woke up, and cursed Wang Xu angrily.

"Haha, I'm just teasing you. Whenever big things happen and you need to be calm, you still need to practice your calm skills." Wang Xu deliberately said it in an old-fashioned way.

"You're right, I'm too excited. Isn't it just a No. 1 achievement in the world? Isn't it a Nobel Prize-level achievement? Why don't you come over and take a look and confirm it?" Professor Duan yelled angrily.

"It's coming, it's coming, Professor Duan calm down, we'll be here soon." Wang Xu stopped interrupting and quickly responded. He was actually excited and couldn't help but start teasing Menzi.

Wang Xu got on the big motorcycle and drove towards the office building of the Department of Materials at lightning speed. He generally doesn't like riding motorcycles on campus. There are too many bicycles and it's easy to get scratched. In the current imperial capital, it's hard to touch up the paint.

But today, he was really excited and wanted to see the results quickly, so he just rode a big motorcycle and went over there in a hurry.

When Wang Xu arrived, Professor Duan and Senior Zhang were still observing the pictures on the screen. Seeing Wang Xu's arrival, Senior Zhang quickly greeted him, asked him to come over and take a look, and then opened a specific photo.

"Look at this, it should be the two-dimensional material we are looking for. I just calculated that the thickness is about 0.35 nanometers, which is equivalent to the height of two carbon atoms. Considering the existence of carbon bonds, this height cannot be two layers of carbon atoms.

Teacher Duan and I have discussed it, and we can confirm that this is a single-layer carbon structure. The specific structure still needs to be analyzed, but the existence of a single-layer graphite can definitely be confirmed. "

The black and white grayscale image shows many large and small mottled black blocks, but there is a transparent square with obvious borders and a small trace of a corner.

It seems, Wang Xu secretly sighed, this is really similar to the pictures he saw on the Internet later. Of course, he also knows that it is easy to calculate the thickness if there are folded corners. It is really difficult to judge a flat square, so All the pictures confirming the existence of graphene are similar.

Then naturally there was a professional discussion, and several people unanimously came to the conclusion that the material with a single layer of carbon atoms was definitely confirmed to exist. The next step is to divide it into two pieces.

The first step is to continue searching to see if there are any other example pictures. After all, only less than one-fifth of the pictures have been analyzed.

The second step is to analyze the structure and physical characteristics of this material and verify the atomic arrangement.

These two issues are beyond what Wang Xu, a second-hand man, can handle. Professor Duan will take over the full responsibility. He will conduct further research and report his findings to the department. It depends on whether to publish a paper on the discovery first, or to do some other research first.

Wang Xu is all-powerful. The discovery of this thing in history was ten years later. If there are no surprises, anything will work.

Anyway, nothing happened to him, so he could go on vacation with his woman without any worries.
