Zhang Ming on the side calmly controlled the tensor-ii research-grade Fourier transform infrared spectrometer in his hand, and the spectrum above was analyzing the changes in the material in front of him.
"Keep heating."
Zhang Ming said to Zhou Sen who was operating at the side. The curve on the spectrometer next to him was constantly fluctuating.
Zheng Sen next to him was responsible for adding some catalysts to the materials in front of him and recording some experimental data.
The three of them worked together, and soon, the graphene in front of them was coated on the silver sheet.
"Check out the effect of silver plating on this graphene."
Zhou Ming said to Zhang Ming who was standing aside.
Zhang Ming nodded, carefully picked up the graphene-coated silver piece with tweezers, and placed it on the glass slide aside.
Start continuing to experiment.
Soon, the physical properties of the silver plate coated with graphene were detected, and everyone frowned and shook their heads.
"Clean up and continue with the second experiment later!"
Zhou Ming said to Zhang Ming and Zheng Sen beside him.
Several people stopped. Zhang Ming and Zheng Sen checked the experimental data and instruments. At this time, Zhou Ming looked at Cheng Hao who was observing curiously and said with a smile: "How is it? Do you think it is very interesting to do the experiment?"
boring?"
Cheng Hao pondered for a moment and shook his head towards Zhou Ming in front of him.
"I think it's okay. After all, the constant repetition of experiments is actually just to find a better possibility. I'm just curious, how does the funding for our laboratory come from??"
Cheng Hao looked at Zhou Ming in front of him curiously and asked.
"We are a laboratory for academicians."
Zhou Ming paused. He looked at Cheng Hao in front of him and said with a smile: "Our laboratory is not short of funds. Not only is it allocated by the state, but there are also state-owned enterprises behind it that send a large amount of funds to our laboratory every year. So,
Our laboratory is not short of funds!”
Hearing Zhou Ming's words, Cheng Hao nodded thoughtfully. At this moment, he suddenly thought of something, and asked Zhou Ming curiously: "By the way, who does the product produced by our laboratory belong to? The country's
?Or corporate?”
"It depends."
Zhou Ming paused.
"Generally speaking, the intellectual property rights of our laboratories are shared by three parties. The laboratory has a part, the state has a part, and the funding company has a part."
"oh!"
Cheng Hao nodded.
At this time, Zhou Ming looked at Cheng Hao with a hint of emotion in his eyes and said: "Actually, doing our kind of experiment is more physical work, especially this new material. Although we understand its physical properties,
However, we still don’t know much about its properties with other materials, and we don’t know much about the effects it produces when mixed with other materials.
It is even more unclear what kind of combination can make this material achieve the best effect, and what is the best effect? In fact, it is difficult to say! This requires testing one material at a time, and then these materials and graphite
What kind of sparks will be produced when ene collides? In fact, it is almost like a lottery.
But the lottery doesn’t need to control the ingredients, we do!”
As he spoke, Zhou Ming smiled bitterly and shook his head.
"Senior, have you achieved anything?"
Cheng Hao looked at Zhou Ming in front of him curiously and asked curiously.
"Yes! Why not?"
Zhou Ming smiled, looked at Cheng Hao in front of him and said.
"We first started studying composite materials of polyvinyl alcohol (PVA) and graphene, and found that the physical and mechanical properties of the two materials were really good when combined. After some experiments, we came up with a composite material with a graphene content of 1.8
vol% polyvinyl alcohol (PVA) composite material, studied its mechanical properties, and found that the tensile strength of the composite material increased by 150%, and the Young's modulus increased by about 10 times!"
"ten times!"
Hearing Zhou Ming's words, Cheng Hao looked surprised in his eyes.
"Um!"
Zhou Ming nodded.
"This material is pretty good, and all three of us got a bonus of 10,000 yuan!"
As he spoke, Zhou Ming showed a smile in his eyes.
"Okay! Let's continue the experiment! Junior brother, you can just watch from the side."
Zhou Ming said to the three people around him.
"Oh! Okay!"
Cheng Hao nodded. Of course he wouldn't have any objections. After all, it was his first time coming to the laboratory, and he still had to listen to his seniors for everything.
Cheng Hao spent the whole day in the laboratory, watching several of his seniors constantly experimenting with different materials, coating or mixing graphene with graphene in different proportions.
Experiment to varying degrees.
At first, Cheng Hao watched with great interest, but by the end, Cheng Hao was numb.
After lunch, I didn’t take much of a lunch break, and the experiment started again in the afternoon.
At this time, Cheng Hao finally couldn't help it. He asked Zhou Ming on the side: "Senior Zhou Ming, what kind of material are we trying to find in this experiment? Or is there no purpose?"
"Of course not!"
Zhou Ming smiled, looked at Cheng Hao and said: "The purpose of our recent experiments is to find a graphene composite material that can be used in space. It needs to have sufficient tensile strength and sufficient Young's
Modulus, the most important thing is the super conductivity of graphene itself, as well as the hardness, which must also be taken into consideration, and it is best to be able to shield the strong radiation from space..."
Hear Zhou Ming's words.
Cheng Hao: "…………"
It sounds very difficult.
"Okay, no more talking! Let's continue processing!"
For one afternoon, Zhou Ming and the other three were doing material experiments, which was boring.
Until the end of the afternoon.
Zhou Ming found Cheng Hao.
"Can you use b?"
b means matrix factory. The software is mainly used in high-tech computing environments for scientific computing, visualization and interactive programming. It has many powerful functions such as numerical analysis, matrix calculation, scientific data visualization, and modeling and simulation of nonlinear dynamic systems.
Integrated into an easy-to-use Windows environment, it provides a comprehensive solution for scientific research, engineering design and many scientific fields where efficient numerical calculations must be performed.
It is a very powerful app. People who do scientific research like this app very much.
Cheng Hao has used it before.
He nodded and said to Zhou Ming in front of him: "Yes!"
week
We still have the test data from many days, so why don’t you take a look at it for us?”
"Can!"
Cheng Hao nodded and agreed.
"Zhang Ming."
Zhou Ming shouted to Zhang Ming who was standing aside.
Zhang Ming took out a USB flash drive from the side, walked to Zhou Ming's side, glanced at Cheng Hao, pondered for a moment, and handed the USB flash drive to Cheng Hao.
"The data here is confidential to a certain extent, please do not disclose it!"
"good!"
After Cheng Hao took the USB flash drive, he quickly said to Zhang Ming.
