Academician Lin nodded, stood up with a smile, and said to Cheng Hao in front of him: "Classmate Cheng Hao, welcome to join our research group!"
As he spoke, Academician Lin stretched out his hand towards Cheng Hao in front of him.
Cheng Hao quickly reached out and shook Academician Lin's hand.
At this time, Academician Lin said to Cheng Hao in front of him with a smile on his face: "Cheng Hao, come on!"
"Okay professor!"
Cheng Hao nodded.
"You go to the laboratory first. If you have any questions, just ask your seniors. You have just come to the laboratory. Do not touch the instruments or anything. You must use them under the guidance of the seniors. Do you hear me?
"
Academician Lin looked at Cheng Hao in front of him seriously and said.
"This is no joke! These instruments are often dangerous!"
"Okay professor!"
Cheng Hao nodded.
"Okay! You go!"
Academician Lin said to Cheng Hao in front of him.
Cheng Hao nodded and walked out of the office.
He had been to the laboratory once, when he and Dean Liu came to see Academician Lin last time, and it was Academician Lin who he found outside the laboratory.
With Cheng Hao's memory, he naturally remembered how to go. Soon, Cheng Hao walked to the laboratory.
At this time, in the laboratory, several senior students were operating an instrument to produce graphene.
Then mix the prepared graphene with some other substances nearby, and then use another instrument next to it to observe the scene in front of you.
The three people worked together, constantly testing and observing, and then moved on to the next goal.
Cheng Hao looked at the scene in front of him with some curiosity.
Not long after, a group of experiments was completed and the three of them stopped. At this time, Cheng Hao walked to Senior Zhou Ming's side out of curiosity.
"Senior, what are we doing?"
"Our current main experiments are to explore the composite materials of graphene materials and the specific applications of this material. At present, we all agree that this material should be feasible in the field of carbon nanotubes!"
Zhou Ming looked at Cheng Hao with some regret and said.
"But there have always been problems with the large-scale production of this material. We are currently also studying how to produce graphene on a large scale. Of course, there are also things about the specific application and material properties of this material. We
It is still in the process of exploration.
After all, it is a new material, and at this stage, there are many people at home and abroad studying this material."
Hearing Zhou Ming's words, Cheng Hao nodded, with a thoughtful look in his eyes.
At this time, Zheng Sen suddenly raised his head, looked at Cheng Hao in front of him and said with a smile: "The biggest trouble we encountered before was the problem of experimental data processing. We are all born in physics and majored in mathematics.
In general, we really don’t know these mathematical models about changes in material properties.
I didn’t expect you to come this time! My junior is really good at math! I guess there shouldn’t be any problem in processing some data, right??”
"Well! As long as I can help everyone, I will try my best!"
"Haha! Junior, you can definitely do it!"
Zheng Sen adjusted his glasses, looked at Cheng Hao in front of him with a smile in his eyes and said: "Your number theory ability can solve conjecture-level problems, and you must have made some achievements in the field of functional analysis!
Isn’t that right! Junior?”
"It's okay!"
Cheng Hao shrugged.
He is telling the truth. He has dabbled in most fields of mathematics, but number theory is the one he studies the most.
When he wanted to study physics, he definitely couldn't miss the field of functional analysis, which was of great help to physics.
Therefore, in addition to the field of number theory, Cheng Hao also knows the most about the field of functional analysis!
"That's ok!"
Zhou Ming smiled slightly.
"In terms of physics, the mathematical category of functional analysis is extremely important, but unfortunately, what we learn is just mediocre."
After saying that, Zhou Ming smiled bitterly and shook his head.
"Forget it, let's not talk about this anymore. Let me explain the instruments in front of me to my junior fellow students! And by the way, I'll teach you how to use them."
Zhou Ming said enthusiastically to Cheng Hao in front of him.
"This tensor-ii research-grade Fourier transform infrared spectrometer is one of the best instruments in our laboratory. It has a built-in gold mirror, and the reflectivity is 6.5% higher than that of aluminum mirrors. It has strong oxidation resistance and optical
The performance is more stable. Dual-channel digital acquisition, four external output optical path expansion, the price is very expensive.
Be careful when you use it!"
Zhou Ming roughly explained to Cheng Hao how to use this instrument, and then talked about the data printing on the instrument.
Then he continued to introduce the second large instrument to Cheng Hao.
"This vacuum ultraviolet laser angle-resolved photoelectron spectrometer is the second most expensive instrument in our laboratory. This thing was developed by China Scientific Research and other foreign places. We also spent a lot of money to purchase it!
"
Zhou Ming sighed slightly and said to Cheng Hao in front of him.
With that said, Zhou Ming introduced several other items in the laboratory, such as centrifuges, some special refrigerators, and several cabinets for various materials.
I probably introduced it to Cheng Hao.
There are many kinds of things that dazzle Cheng Hao, which means that Cheng Hao's brain rotates faster than ordinary people. Otherwise, ordinary people would have fainted by now.
Cheng Hao's eyes lit up the more he listened.
"Okay! Let's start the second set of experiments!"
Zheng Sen on the side said to Zhou Ming in front of him.
Zhou Ming nodded, and he said to Cheng Hao in front of him: "Brother Cheng Hao, first take a look at how we did the experiment, and then you can record the process. After we produce the data later, we will ask you to record it.
one time!"
"clear!"
Cheng Hao nodded.
At this time, Zhou Ming hurriedly started to walk over.
Zhou Ming began to produce graphene.
Cheng Hao looked at Zhou Ming's movements with some curiosity.
Zhou Ming skillfully introduced n2 and ar gas into the graphite, and then heated it.
Soon, the graphite oxide expanded rapidly and peeled off, causing part of the oxygen-containing groups to pyrolyze to generate CO2. Soon, Zhou Ming obtained some graphene.
After successfully manufacturing graphene, it is not finished.
Zhou Ming started electrolysis, put it together with the silver that had been prepared nearby, mixed it in equal proportions, and heated it. The electro-optical lens next to him kept observing the scene in front of him.
Silver and graphene were fused at high temperatures, and the three people on the side looked at the scene in front of them with serious expressions.
