Chapter 241 (1/2)
Li Zheng had a solid foundation. After more than ten minutes (hours) of special study, he stepped into the laboratory and was naturally as stable as Mount Tai.
But in Hu Zengwu's eyes, it's totally different.
This is not only in contempt of chemistry, but also in contempt of scientific research itself.
Seeing that the teacher was going to get angry, Shen Yiyun quickly put down the matter in his hand and stopped him: ”don't make trouble, Li Zheng Why don't you go first... ”
”No...” Li Zheng explained, ”after all, I have studied under Mr. Hu before. I just read the papers written by Mr. Hu's research group in recent years, and I know a little about photovoltaic research. I know most of the contents you just showed me. Just confirm the progress of the experiment.”
Hu Zengwu heard the speech, and his expressionless old face suddenly trembled: ”you? Look at our group's papers? When I was studying under me? ”
”Yes.” Li Zheng nodded steadily.
Unknowingly, Li Zheng's lying skills also increased with age and experience.
Hu Zengwu blushed a little.
After all, he never taught Li Zheng.
What's more, will Li Zheng really study the thesis of this research group with an open mind?
It's more like
A full range of research opponents, so convenient to find fault?
However, Li Zheng has already been in charge of his work and said: ”I found that Mr. Hu has been immersed in the photovoltaic field for more than 10 years. He has studied and iterated over 30 versions of photovoltaic materials. He has led the national scientific research team in this field, from the initial fluorination route to the present chlorination route, and can work out a more optimized design almost every few months. It's an honor for me to have the chance to be part of it. ”
Hu Zengwu said this, which called a panic.
Is this really Li Zheng?
Sex change?
Even Shen Yiyun doesn't know what to say.
Li Zheng looked at Shen Yiyun with some dissatisfaction and said, ”you, too, have the honor to join such a dynamic research group and make outstanding contributions to China's solar power industry at the graduate stage. How can you still have time to take a vacation?”
”Ah...” Shen Yiyun understood this.
Good, you fine eyebrow sharp face, tooth for tooth, this is double repay.
On the other side, Hu Zengwu turned his head and said reluctantly, ”then you should be very clear about the specific work of Yiyun now?”
Li Zheng replied without hesitation: ”well, through chlorination to optimize the receptor molecule y6, try various new receptors, and compare their electronuclear transmission efficiency.”
”Well...” Hu Zengwu scratched his burning face First help Yiyun to do it together. Pay attention to the safety of the experiment. It's hard. ”
”No hard work, no hard work.”
Li Zheng and Shen Yiyun came to the experimental platform and could not wait to rub their hands.
Finally, we can touch the top equipment.
He used many things before, but he didn't expect that the scientific research laboratory could be more advanced.
Take liquid treatment, for example, the competition is treated with a dropper and a measuring cup, the highest end of which is water bath distillation.
But here, if you have enough pressure, you can use the magic pipette to measure the liquid.
It looks like a hand-held code scanner. You can adjust how much liquid it takes and how much liquid it puts on the panel. There is a row of droppers under it, which can operate in multiple tubes at the same time.
It's easy and accurate, and you don't have to worry about Shibao's ”one pinch” monster.
The bad news is that this gadget with Thermo Fisher Scientific will cost more than 30000.
Forget it, let's continue to use the rubber tube
In the process of preparation in collaboration with Shen Yiyun, Li Zheng is also a part of scientific research.
What he said before was not blind. Hu Zengwu's team has been doing photovoltaic research for ten years.
To be sure, it's organic photovoltaic cells, the kind used in solar power plants.
Even laymen also know that the difficulty of solar power generation is not ”taking”, but ”saving”.
In other words, the efficiency and cost of the battery are the top priority.
For a long time, the mainstream of the market has been the inorganic battery based on silicon. The efficiency is fair, but the cost is high.
Organic batteries only exist in the laboratory, and the cost is 10% to 20% of the cost of inorganic batteries, but the photoelectric conversion efficiency is also poor.
Therefore, Hu Zengwu's research group locked in the direction of ”organic photovoltaic cells” ten years ago, cooperating with a number of universities and science centers. In 10 years, it has improved the efficiency of organic cells to 70% of inorganic ones and reduced the cost by 40%.
Up to now, China has become the international leading level in this field, and the organic battery is only one step away from commercial use.
This is the researcher. They are just an ordinary uncle with thin hair on the street.
Only in areas that most people don't understand, where they don't know, can they really shine.Until their results are delivered to people in a convenient and inexpensive way, people may not be aware of their existence.
If solar power generation can be understood to some extent, it is impossible to understand Li Zheng's experiment now.
he and Shen Yiyun are changing the length of alkyl groups at the edge of Y receptor to enhance its ”conductivity” by a few thousandths.
To put it more bluntly.
Y receptor is about a ghost thing that puts together the big rings in the 10 circle topics.
There will be many tentacles on the edge of this ghost. Li Zheng needs to stretch them again and again, cut them short, and record the changes of a series of ”conductive” parameters.
Shen Yiyun has done this kind of work thousands of times.
As for how many times Hu Zengwu has done, it is impossible to know.
And the experiment like this is only one of more than ten experimental projects of the whole research group.
……
In the afternoon, the alarm clock of Shen Yiyun's mobile phone suddenly rings.
She gritted her teeth and glanced at Hu Zengwu, who was immersed in the photoelectric experimental platform, and turned off the alarm clock in silence.
”What time is it?” Hu Zengwu asked, operating the electronic screen.
”It's more than four o'clock, Miss Hu...” Shen Yiyun carefully said, ”we just made two groups...”
”Well The closing ceremony is about to start. ” Hu Zengwu did not raise his head, waved his hand, ”you go, also help me to see if this year there is a team champion.”
”Thank you, Miss Hu!” Shen Yiyun was happy, and quickly pushed Li Zheng to say, ”clean up quickly, clear up quickly...”
”Make another group...” Li Zheng flushed his face and wiped his sweat, ”btp-ec9, I feel very promising, more whole point.”
“！！！” Shen Yiyun gritted his teeth.
You are jumping into hell!
”Well, let's call it a day. Make a good record of the experiment. Btp-ec9 and I'll test the photovoltaic efficiency.” Hu Zengwu is rarely in a good mood. He looks up at Li Zheng and laughs, ”today is to understand scientific research?”
”It's too early to understand. It's not even an introduction...” Li Zheng scratched his head and said, ”I'm excited on the first day. I've been doing it for years. It's not sure that half a year's work can improve one thousandth of the total. I'm not sure that I can't stand it.”
”No way. That's what real research is like.” Hu Zengwu shook his head and sighed, ”so those who don't know much prefer physics and mathematics. They always think that they will become Newton and Einstein by patting their heads, but they don't know that the real achievements are all made little by little.”
”I really benefited a lot today. Thank you, Mr. Hu.” Li Zheng nodded respectfully.
”Well, pack up and go.” Hu Zengwu turned his head again, waved his hand, hesitated and said, ”well My research group In fact, some people are recruiting recently Although it is written above graduate students However, it is not impossible to consider the occasional excellent undergraduate students... ”
Li Zheng was stunned and didn't reply. He first felt Shen Yiyun's burning eyes.
Looking around, Shen Yiyun is shaking his head with the smallest amplitude and the highest frequency.
No, no, No This is the call of hell.
Li Zheng coughed and said thanks again. Then he slipped out with Shen Yiyun.
They changed their clothes, took two bottles of nutrition express, and escaped from the experimental building all the way. Shen Yiyun gasped and said, ”he He lied No recruitment at all He is your craft. ”
”I also feel that...” Li Zheng looked at his hands and said, ”then I can't expose myself any more...”
”Anyway Just as a sex man would crave a girl with good figure, an old professor would also like to have a good student's craft. ” Shen Yiyun looked at Li Zheng and solemnly said, ”you and Shi Yang are basically equal to Diao Chan and Xi Shi in our circle, but you must be careful not to be watched by a professor with a bad heart.”
Li Zheng tried to imagine for a moment, and then
”Ouch...”
”What's the matter?”
”Imagine shiper dancing in a mink cicada dress.”
”Ouch...”
……
In the corner of a water bar on Jida campus, Shen Yiyun leads Li Zheng to get together with two brothers who have experienced the competition.
It's not official. It's a live broadcast by a teacher with the team. Li Zheng also conveniently sent the link to Longzhu group for dissemination.
After everyone got to know each other, the two big brothers could not wait to start persuading them to quit.
”Brother bang, we must not touch chemistry.”
”Four tiankengs of biochemical ring material! Really, don't touch any of them. ”
”Well, I didn't accept Now, after three years of college, two and a half years, I've been trying to find a way to transfer departments. ”
”Can you imagine When you were in school, you were in the lab every day, pouring those liquids You're retired, you're still in the lab, you're still dumping the liquid”Some of the tumultuous is good, do you know how many people have no qualification to pour liquid?”
”Ah, sister may also be a little cheaper. Many teachers like to accept sister, but not for experiments. It is mainly for encouraging the men in the laboratory. Each can improve the efficiency of 15%, and the sister will not accept it in vain. No, no, no Nothing else, sister Shen Xuejie, you are level It's not a tool buff. ”
Li Zheng deeply accepted their advice and retreated. Seeing that the closing ceremony on pad screen was almost started, Li asked, ”have you ever participated in IChO?”
”No.” ”It's just national silver,” the graduate guy said
”I'm saving one.” ”Hunan Province 1,” the bachelor big guy laughs
Graduate big man busy arch hand: ”originally you are Hunan, that is more than our country silver cow force.”
”Ah...” ”It's too hard, it's really hard in southern Hunan, and it's hard to come out with a god of joy, and last year it was that result Everybody scolded us for being in southern Hunan Alas! ”
”No panic, I'll get it back this year.” After the graduate students took the photos of undergraduates, he rushed to Li Zheng, ”in fact, we also feel that there are problems. I have suffered losses last year. How can we save one person this year. Li Zheng, your level is here, and go with Shiyang. The champion can run? ”
”Hi, no, no more.” Li Zheng chuckled, ”it was a little noisy at that time, very immature.”
”It's going to change sooner or later. You just missed the good time, brother.” The undergraduate also looked at Li Zheng with great regret, ”anyway, I don't plan to do chemistry, so don't think more about it.”
”Don't think much, don't think much, just think about the group champion.” Li Zheng replied with a smile.
Not long ago, the closing ceremony officially began, the big guys of the international chemical association began to give a speech on the stage. In fact, several people sitting in the room were able to understand their efforts, but they were not in any mood to listen to it, only thinking about the results.
live broadcast bullet screen comments are awesome.
I will translate. 】It is very happy that after 50 years, IChO has returned to Prague again 】But no one is watching his translation.
