Xueba's Sea of ​​Stars

Chapter 285 The joy of success...?
In the laboratory, Wu Bin first thermally reduced graphene oxide into graphene nanosheets under the protection of nitrogen, and then ultrasonically oxidized the graphene nanosheets in a mixed acid with a volume ratio of VH2304/VHNO31 of 1:3.

Wu Bin did a series of operations very seriously, and he kept improving the details. He would record every reaction one by one and make a series of associations, so during the experiment, he never had anything to do with boredom.

At this time, Wu Bin is using the most common hydrothermal method to prepare graphene quantum dots. The cost of this preparation method is relatively low, and Wu Bin can obtain a little more information when making it.

"Snapped!"

After closing the densely packed notebook, Wu Bin placed the oxidized graphene nanosheets in the high-pressure reactor.

'Tsk, I really want to try YZUR300. '

For a high-pressure reactor, a machine that needs to meet high temperature and high pressure in scientific research, the ultrasonic probe can be said to be the most important component.

But there are very few types of broken heads in the laboratory. Although Wu Bin reported this last year, it has not been implemented yet. This makes all kinds of tricks pop up in his mind every time he does the experiment, but he is limited by the lack of tools. Yes, he is very uncomfortable.

And the YUZR300 he is thinking about also has an ultrasonic generator with timing and program programming functions.

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 started using the reactor to thermally cut the graphene nanosheets at 200°C.

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

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

Some time ago, Wu Bin decided to use the liquid phase method to synthesize calcium hydroxide and graphene quantum after various brainstorming, but the process was extremely unsmooth because the component content could not always reach a balance.

But this time, Wu Bin had another very novel idea.

"Huh..." After taking a long breath, the data formula in Wu Bin's mind went into carnival again.

……

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

"Otherwise?" Xie Hui, who was not far away, turned around his chair and responded.

"I'm ashamed that he is so hardworking. His attendance rate in these two weeks is probably higher than ours combined." Tang Fang laughed at himself while chewing on a hot dog.

After hearing this, Xie Hui couldn't help giving him a blank look: "Then you should be more diligent. You only come to the laboratory at this hour. You really can indulge yourself when the boss is not around?"

"I'm wronged, I just checked the materials from the library, okay?"

"I believe it." Xie Hui said "haha"

And just when Tang Fang wanted to argue a few more sentences, he suddenly heard the sound of the door being opened.

The two turned around and saw that it was Wu Bin standing at the door holding a large file bag.

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

"The boss is going to a meeting. If you have anything to do, tell me directly. Is it a problem with the equipment?" Xie Hui stood up and said to Wu Bin with a smile.

"Oh no, my experiment has been initially 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 bite of the hot dog into his mouth, didn't finish his mouth for a long time. He just looked at Wu Bin with a dazed expression, his eyes full of horror.

"Wait a minute...wait a minute first," Xie Hui raised his hand and patted his forehead, "My mind is a little confused. What preliminary method are you talking about?"

"Oh, I have successfully used the confinement effect of graphene quantum dot surfactants to effectively regulate the nucleation and growth kinetics of calcium hydroxide, allowing the controllable synthesis of calcium hydroxide nanomaterials, but there are many other aspects of synthesis. There is room for improvement, so I want to talk to Professor Zhang."

"You...you have succeeded!?" Xie Hui exclaimed, "You have successfully introduced graphene quantum dots into inorganic materials!!?"

"Well, the synthesized material is 80 nanometers, uniform in size, and has UV resistance. It should be very suitable for protecting murals."

"Damn... Fuck! Fuck!?" At this moment, Tang Fangmeng, who finally swallowed the hot dog, was in a daze. He only hated himself for not learning Chinese well. words to express your feelings.

"I...you...well, I'm going to call Professor Zhang right now." Xie Hui on the side didn't feel any better, and after dancing for a while, he ran out of the laboratory with his mobile phone.

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

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

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

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

"It shouldn't be you who pushed open the door hard, and then shouted at us out of breath, 'I succeeded! I finally succeeded!', and then we first looked dumbfounded, and then hugged you in ecstasy after reacting, and finally Do the three of you hug each other and cry?"

"???"

Seeing Wu Bin tilting his head with a "WTF" expression on his face, Tang Fang grabbed his shoulder and said, "Scream! Release the joy in your heart, we can totally understand it!"

"Okay, okay, don't play tricks on you." When Wu Bin was confused again, Xie Hui came over and pulled Tang Fang away, and said to Wu Bin with a smile: "Don't pay attention to him, he is so happy."

"Oh, I'm very happy too." Wu Bin nodded with a smile.

"Really, I really can't see it." Xie Hui said, looking at the key technology research of field emission cold cathode opened by Wu Bin, he couldn't help asking: "Are you... are you going to start the next project immediately?"

"Oh, no." Wu Bin shook his head, "I just saw it when I browsed the magazine's website two days ago. I thought it was very interesting, so I put it in the computer. I happen to be free right now, so I took a look."

"Hahaha, you really don't leave us any way to survive." Xie Hui was really convinced this time, it was really the first time he saw someone would continue to work hard at such a peak moment in life. Read the literature.

"Oh, so I said it, geniuses have already worked hard like this, so what's the use of our efforts?" Tang Fang, who looked extremely frustrated, said in a helpless tone.

"Okay, okay, I know that your mentality is broken and you are going to die in despair, but I also want to gain a little more success." Xie Hui made a driving gesture to Tang Fang and said.

"How could it be possible for you to enjoy it exclusively, the VIP seat on the thigh is reserved for me!"
