In the laboratory, Wu Bin first thermally reduced graphene oxide to graphene nanosheets under nitrogen protection, and then ultrasonically oxidized graphene nanosheets into mixed acid with a volume ratio of VH2304/VHNO31 of 1:3.

A series of operations Wu Bin did very seriously, and he kept improving in details, he would record every reaction one by one, and make a series of associations, so in the experiment, he never felt bored.

At this time, Wu Bin was using the most common hydrothermal method to prepare graphene quantum dots.

The cost of this method is relatively low, and Wu Bin can obtain more information during production.

"Smack!"

Closing the dense notebook, Wu Bin placed the graphene nanosheets that had been successfully oxidized in the high-pressure reactor.

'Tsk, I'd like to try YZUR300. ’

For high-pressure reactors, which need to meet the high temperature and high pressure in scientific research, the ultrasonic probe can be said to be the most important part.

However, there are very few types of broken heads in the laboratory here, although Wu Bin has reported this last year, but it has not yet been implemented, which makes him very uncomfortable when he has all kinds of commotions in his mind every time he experiments.

And the YUZR300 he had in mind also had an ultrasound generator that could be timed and programmed.

With controllable amplitude and frequency, it ensures that Wu Bin can produce the best ultrasonic cavitation effect when working at any power.

After sighing, Wu Bin began to use the reactor to start thermal cutting of graphene nanosheets at 200 °C.

The diameter of graphene nanosheets prepared by hydrothermal method is mainly distributed between 5 and 14 nm, and the quantum dots have strong optical absorption in the ultraviolet region, and when the excitation wavelength is 60 nm, the quantum dots will emit bright blue light.

This property allows graphene quantum dots to effectively mediate the photoluminescence properties of graphene quantum dots through the migration effect of functionalized substances.

Some time ago, after various brainstorming, Wu Bin decided to use the liquid phase method to synthesize calcium hydroxide and graphene quantum default chaptering [12] points, but the process was unusually smooth, and the balance in the component content could not be reached.

"Breathe ......" Wu Bin, who breathed a sigh of relief, the data formula in his brain carnival again.

……

"Wu Bin is doing a test again?" Tang Fang, who came to the laboratory with a hot dog, looked at Wu Bin's empty seat and asked casually.

"Or else?" Not far away, Xie Hui turned his chair and answered.

"I'm embarrassed that he's so hardworking, I'm afraid the attendance rate in these two weeks is higher than ours combined." Xie Hui chewed on the hot dog and laughed at himself.

Xie Hui couldn't help but glance at him after hearing this: "Then you should be diligent, you only came to the laboratory at this point, can you really indulge in fooling around when the boss is not there?" ”

"Wronged, I just came from the library to check the materials, okay."

"I believe it." Xie Hui looked "hehe"

And just when Tang Fang was about to argue, the office door was suddenly opened.

The two turned around and found that it was Wu Bin who walked in with a large file bag.

"Is Professor Zhang here today?" Wu Bin looked at Xie Hui and asked.

"The boss went to a meeting, what do you have to tell me directly, or is it a problem with equipment?" Xie Hui stood up and said with a smile.

"Oh no, my experiment has been preliminarily successful, so I want to bring my research report to Professor Zhang."

“……”

After listening to Wu Bin's words, Tang Fang, who stuffed the last hot dog in his mouth, didn't put his mouth down for a long time, and just looked at Wu Bin with a confused face, his eyes full of horror.

"Wait a minute......" Xie Hui raised his hand and patted his head, "My brain is a little messy, what kind of preliminary are you talking about?" ”

"Oh, I have successfully used the confinement effect of graphene quantum dot surfactant to effectively regulate the nucleation growth kinetic rate of calcium hydroxide, so that calcium hydroxide nanomaterials can be synthesized in a controlled manner, but there are still many things that can be improved in terms of fusion, so I want to talk to Professor Zhang."

"You...... Aren't you a success!? Xie Hui exclaimed, "You have successfully introduced graphene quantum dots into inorganic materials!? ”

"Well, the synthetic material is 80 nanometers, uniform in size, and has UV resistance, which should be very suitable for the protection of murals."

"it...... it! it!? At this time, Tang Fangmeng, who finally swallowed the hot dog, was a stunned three-in-a-row, only hating himself for not learning the language well, and at this moment he could only think of using the word "slot" to express his feelings.

"I ...... You...... That, I'm going to call Professor Zhang right now. Xie Hui on the side was not much better, and ran out of the laboratory with his mobile phone after dancing for a while.

After a while, Xie Hui ran back to the office with his mobile phone and said, "Professor Zhang said he will be back soon." ”

"Okay." Wu Bin nodded, then sat in his seat, turned on the computer, and began to read the literature.

At this time, Tang Fang, who had recovered a little, trotted all the way to Wu Bin, looked at him and asked, "Wait, this plot is completely wrong!" ”

"What's the plot?" Wu Bin, who was opening the materials science folder, turned his head and asked.

"It wasn't like you pushing the door open and panting and shouting at us, 'I made it!' I finally made it! Then we first looked confused, and after reacting, we hugged you in ecstasy, and finally the three of us hugged and cried together? ”

“？？？”

Seeing Wu Bin tilting his head with a "TF" expression, Tang Fang grabbed his shoulder and said, "Scream!" Unleash the joy in your heart, we can understand it! ”

"Okay, okay, don't play tricks on you," when Wu Bin looked confused again, the association came over and pulled Tang Fang away, and said to Wu Bin with a smile: "Don't pay attention to him, he is too happy." ”

"Oh, I'm so happy." Wu Bin smiled and nodded.

"yes, I really can't see it." Xie Hui said and glanced at the key technology research of field launch cold cathode that Wu Bin clicked on, and couldn't help asking: "What are you...... Ready to start the next topic? ”

"Oh no." Wu Bin shook his head, "I saw it when I visited the magazine website two days ago, and I thought it was quite interesting and put it in the computer. ”

"Hahaha, you really don't leave us with any way to live." Xie Hui was really convinced this time, he really saw someone who would continue to read literature carefully at such a peak moment in his life.

"Alas, so having said that, geniuses have already worked hard to become like this, so what's the use of us working hard?" Tang Fang's expression, which was extremely depressed, was full of helplessness.

"Okay, okay, I know that your mentality has collapsed, and you are going to mourn to the side, and I want to rub more halo of success." Xie Hui made a gesture to Tang Fang and said.

"How can you let it be exclusive, the VIP seat on the thigh is reserved for me!"
