Learning Demon Cultivation System

"Hey, it doesn't matter, anyway, it's impossible to read it in one day." Shen Yiyun said and opened the filing cabinet in the corner, "Just pretend to look at it twice, and then say hello that you don't understand, you can just withdraw Already, I will give you the contact information of the senior brother, you go to him, and we will watch the closing ceremony together then."

She spoke casually, but Li Zheng had already put down his schoolbag, pulled out a set of stationery that he had prepared for the physical training camp, and placed them squarely on the table.

After the preparations were complete, Li Zheng sat at the table, moved his fingers and said, "I remember, the core is to enhance the charge transfer effect within the molecule by introducing dichlorocyanindanedione as the end group, right?"

Shen Yiyun flipped through the files and sighed blankly: "Ah... yes... your memory is really good..."

"I haven't read chemistry in the past few months, and it's far behind." Li Zheng intertwined his hands, thrust forward with his backhand, stretched his tendons and sneered, "It's just to make up for the regret of IChO. Today, Shi Yang and I exist."

"Damn..." Shen Yiyun cursed, "Because of no reason, he became serious."

At the same time, Hu Zengwu's serious voice came from the laboratory: "Yiyun?"

"Come on, come on."

"Let Li Zheng go if he doesn't understand. Don't waste everyone's time."

"Ah, Li Zheng looks very serious, why don't you let him try?"

"Let him go."

……

Not long after, Shen Yiyun opened three super long papers on the computer, and sent a stack of paper materials related to the experiment.

"These are the principles and applications." Shen Yiyun patted the materials on the table after pointing to the computer screen, "These are the operating specifications, workflow, and recording specifications of the relevant instruments. If you master them all, they can basically be regarded as scientific research. assistant."

"I don't care about anything else." Li Zheng rolled up his sleeves, "Shi Yang has everything under control, right?"

"Able to enter Zhou Yi's laboratory...it should be..."

"As long as I'm no worse than him, you can do your work." Li Zheng waved his hand in disgust.

"Oh... If you can't bear it, just say it when you leave..."

Shen Yiyun then entered the laboratory, came to the familiar experimental bench, and silently prepared the experiment that had been performed thousands of times.

This is the case with scientific research experiments. In order to find out a principle and optimize a process, it usually takes tens of millions of repetitions, and then changes a variable or condition, and then repeats it tens of millions of times.

It took a long time and it was exhausting, but it had to be done.

During the preparation, Hu Zengwu asked indifferently: "I heard you just said that he originally came to Wujing for training, but then he felt bored and left?"

"Seems to be."

"It muddied the chemistry training, and messed up the physics again." Hu Zengwu pursed his lips and said, "It must be difficult for the training teacher."

"Hmm... I don't know why this training camp was taken away... He seems quite happy to hear that Li Zheng is gone."

"Oh, okay, the flies looked at the mung bean, and they met eyes." Hu Zengwu rarely laughed, "A person who is unruly and eager for success, no matter how good his brain is, he can only achieve nothing..."

"This... Teacher Hu, Li Zheng is actually quite down-to-earth."

"It's not something you can see, it's made." Hu Zengwu pouted outside the laboratory, "If he can sit until we get off work today, and study hard for seven or eight hours, he can be regarded as steadfast. There is room for redemption."

Hu Zengwu's voice just fell.

The stern, handsome man in a white coat has stepped into the laboratory with his hands raised.

"I'm ready."

He nodded.

Chapter 241 Youth belongs to blue and white

Li Zheng already had a solid foundation. After more than ten minutes (hours) of special study, he stepped into the laboratory, and he was naturally as stable as Mount Tai.

But in Hu Zengwu's eyes, it is completely different.

This is not only despising chemistry, but also despising scientific research itself.

Seeing that the teacher was going to get angry, Shen Yiyun quickly put down what he was doing and stopped him: "Stop making trouble, Li Zheng...how about you go first..."

"No..." Li Zheng explained, "After all, I studied under Mr. Hu before, and I just read the papers of Mr. Hu's research group in recent years, so I know a thing or two about photovoltaic research. Just now you showed me I understand most of the contents, just confirm the progress of the experiment."

When Hu Zengwu heard the words, his expressionless old face suddenly trembled: "You? Read the papers of our group? When I was studying under my staff?"

"Yes." Li Zheng nodded steadily.

Unknowingly, Li Zheng's lying skills have also improved a lot with age and experience.

Hu Zengwu blushed a little.

After all, he had never taught Li Zheng before.

Moreover, would a person like Li Zheng really be modest enough to study the papers of this research group?

It's more like...

It's easy to find faults by studying opponents in all aspects, right?

However, Li Zheng stood with his hands behind his back and talked eloquently: "I just found out that Mr. Hu has been immersed in the photovoltaic field for more than ten years. He has researched and iterated more than 30 versions of photovoltaic materials and led the country's scientific research in this field. The team, from the initial fluorination route, all the way to the current chlorination route, can research a more optimized design almost every few months. It is my honor to have the opportunity to participate in it occasionally."

Hu Zengwu was frightened by what he said.

Is this really Li Zheng?

Transsexual?

Even Shen Yiyun didn't know what to say.

However, Li Zheng looked at Shen Yiyun with some dissatisfaction and said, "Sister, you are too. You are lucky enough to join such a dynamic research group and have made outstanding contributions to my country's solar power generation at the graduate level. How can you still have time off?"

"Ah..." Shen Yiyun finally understood.

Well, you slender brow and pointed face, if you retaliate with an eye, this is double repayment.

On the other side, Hu Zengwu turned his head and said unwillingly: "Then you should be very clear about Yiyun's specific work now?"

Li Zheng replied without hesitation: "Well, optimize the receptor molecule Y6 by chlorination, try various new receptors, and compare their electronuclear transfer efficiencies."

"Hmm..." Hu Zengwu scratched his burning face, "Then you...help Yiyun do it first, pay attention to the safety of the experiment, thank you."

"Not hard, not hard."

Only then did Li Zheng and Shen Yiyun come to the experimental platform and rubbed their hands impatiently.

Finally, you can touch the top equipment.

He has used many things before, but he didn't expect that the scientific research laboratory can be more advanced.

Take liquid processing as an example, droppers and measuring cups are used during competitions, and the highest end is water bath distillation or something.

But here, if you are pushy enough, you can use the magic pipette to measure the liquid.

This thing 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 also a row of droppers below, which can operate multiple tubes at the same time.

It is easy and accurate, and you don’t have to be afraid of monsters like Shi Bao’er who take the liquid in one pinch.

The bad news is that this gadget with ThermoFisher Scientific printed on it costs more than 3 yuan.

Forget it, let's continue to use rubber test tubes...

In the process of co-preparing with Shen Yiyun, Li Zheng also got a glimpse of scientific research for the first time.

What he said before was not beeping. Hu Zengwu's team has indeed been engaged in photovoltaic research for ten years.

Organic photovoltaic cells, the kind used in solar power plants, to be precise.

Even a layman knows that the difficulty of solar power generation is not "taking", but "saving".

In other words, battery efficiency and cost are the top priorities.

For a long time, the mainstream of the market has been inorganic batteries based on silicon-based batteries, which have acceptable efficiency but are expensive.

Organic batteries only exist in laboratories, and their cost is 10% to 20% of inorganic batteries, but the photoelectric conversion efficiency is also pitifully low.

Therefore, Hu Zengwu's research group locked in the direction of "organic photovoltaic cells" ten years ago, and cooperated with many universities and science centers. It took 10 years to increase the efficiency of organic cells to 70% of inorganic cells. By the way Another 40% cost reduction.

Today, my country is already an international leader in this field, and organic batteries are only one step away from commercial use.

This is the scientific research personnel, they are just an ordinary uncle with thinning hair walking on the street.

They really shine only in areas and places that most people don't understand at all.

Until their results are delivered to people in a convenient and cheap way, people may not realize their existence.

If solar power generation can be understood to some extent, it is impossible to understand the experiment that Li Zheng is going to do now——

He and Shen Yiyun are changing the length of the alkyl group on the edge of the Y receptor, just to increase its "conductivity" by a few thousandths.

To put it more bluntly.

The Y receptor is probably a ghost thing that put together the big rings in 10 Zhou Chenghuan's questions.

There will be many tentacles on the edge of this ghost thing. Li Zheng needs to stretch them, cut them short, and record the changes in a series of "conductive" parameters time and time again.

Shen Yiyun has done this kind of work thousands of times.

As for how many times Hu Zengwu did it, there is no way of knowing.

An experiment like this is only one of the dozen or so experimental projects of the entire research group.

……

At four o'clock in the afternoon, the alarm clock on Shen Yiyun's phone suddenly rang.

She gritted her teeth and glanced at Hu Zengwu, who was immersed in the photoelectric experiment bench, and silently turned off the alarm clock.

"What time is it?" Hu Zengwu asked while operating the electronic screen.

"It's past four o'clock, Mr. Hu..." Shen Yiyun said cautiously, "We just did two sets..."

"Well... the closing ceremony is about to begin." Hu Zengwu waved his hands without raising his head, "You guys go, and help me see if I have won the team championship this year."

"Thank you, Mr. Hu!" Shen Yiyun was overjoyed, and hurriedly pushed Li Zheng, "Clean it up, clean it up..."

"Let's do another set..." Li Zheng wiped off his sweat with a flushed face, "I think BTP-eC9 has a bright future, let's do more."

"!!!" Shen Yiyun gritted his teeth.

You are jumping into hell!

"Okay, let's stop here today, make good experimental records, I'll test the photovoltaic efficiency of BTP-eC9 later." Hu Zengwu was in a rare good mood, looked up at Li Zheng and smiled, "Today is considered to be an understanding of scientific research. ?”

"It's still early to understand, and it's not even a beginner..." Li Zheng scratched his head and said, "I was excited the first day. It really made me do it for years and months. Even half a year may not improve by a thousandth. I guess I will also suffer. Can't live."

"No way, that's what real scientific research is like." Hu Zengwu shook his head and sighed, "So people who don't know much prefer physics and mathematics. They always think that they can become Newton and Einstein with a slap in the head, but they don't know the real results. , It’s all boiled out bit by bit.”

"I really benefited a lot today, thank you Teacher Hu." Li Zheng nodded respectfully.

"Okay, pack up and go." Hu Zengwu turned his head again, waved his hands, and said hesitantly, "Well...my research group...has actually been recruiting people recently...although the writing is for graduate students and above... ...But occasionally there are outstanding undergraduates, it is not impossible to consider..."

Li Zheng was taken aback for a moment, before he could reply, he first felt Shen Yiyun's burning gaze.

Turning his head to look, Shen Yiyun was shaking his head desperately with the smallest amplitude and the highest frequency.

Don't, don't...it's a call from hell.

Li Zheng coughed, thanked him again, and then slipped out with Shen Yiyun.

The two changed their clothes in embarrassment, smoked two bottles of Nutrition Express, and escaped from the laboratory building all the way, before Shen Yiyun gasped and said: "He...he lied to people...he didn't recruit at all...he is just greedy for your craft."

"I also think..." Li Zheng looked at his hands and said, "Then I can't expose myself any more..."

"Anyway... Just like a perverted man will be greedy for a girl with a good figure, the old professor will also be greedy for a student's craftsmanship." Shen Yiyun looked at Li Zheng and said solemnly, "You and Shi Yang are basically the same in our circle. Diao Chan and Xi Shi, please be careful not to be targeted by professors with malicious intentions."

Li Zheng tried his best to imagine, and then...

"vomit……"

"What's wrong?"

"Imagine Shi Baoer dancing in Diao Chan's clothes."

"vomit……"

……

On the campus of Ji University, in a corner of a water bar, Shen Yiyun led Li Zheng, and got together with two brothers who had experience in chemical competition.

It is said to be a live broadcast, but it is not an official one, but a certain team teacher used his mobile phone to broadcast the live broadcast. Li Zheng also sent the link to the Dragon Ball group so that everyone can spread it.

After everyone got to know each other, the two big brothers couldn't wait to persuade them to leave before the awards ceremony started.
