Li Zheng already had a good foundation. After more than ten minutes (hours) of special study, he stepped into the laboratory and felt as stable as a rock.

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

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

Seeing that the teacher was about to get angry, Shen Yiyun quickly put down what he was doing and stopped him: "Stop making trouble, Li Zheng... Why don't you leave first..."

"No..." Li Zheng explained, "After all, I have studied under Teacher Hu before. I happened to read the papers of Teacher Hu's research group in recent years, and I know a little bit about photovoltaic research. You just showed it to me. I understand most of the contents, I just need to confirm the progress of the experiment."

When Hu Zengwu heard this, his expressionless face suddenly trembled: "You? Read our group's papers? When you were studying under me?"

"Yes." Li Zheng nodded steadily.

Unknowingly, Li Zheng's lying skills have improved dramatically with age and experience.

Hu Zengwu blushed a little.

After all, he never taught Li Zheng anything.

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

This is more like...

Studying opponents in all aspects makes it easy to find faults, right?

However, Li Zheng was already standing with his hands behind his back, talking eloquently: "I found out at first glance 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 area. The team, from the initial fluorination route to the current chlorination route, can develop a more optimized design almost every few months. It is an honor for me to have the opportunity to participate in it."

These words made Hu Zengwu frightened.

Is this really Li Zheng?

Transitioned?

Even Shen Yiyun didn't know what to say.

Li Zheng looked at Shen Yiyun with some dissatisfaction and said: "Senior sister, you are the same. You are lucky enough to join such a dynamic research group and have made outstanding contributions to my country's solar power generation industry during your graduate period. How can you still have time to take a vacation?"

"Ah..." Shen Yiyun finally understood.

You are such a thin-browed and sharp-faced person. To retaliate with tooth, this is double repayment.

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

Li Zheng replied without hesitation: "Well, we optimize the receptor molecule y6 through chlorination, try various new receptors, and compare their electro-nuclear transmission efficiency."

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

"It's not hard, it's not hard."

Li Zheng and Shen Yiyun then came to the experimental table and rubbed their hands impatiently.

Finally, I can touch top-notch equipment.

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

Take liquid processing as an example. During competitions, droppers and measuring cups are used for processing. The most advanced ones are water bath distillation or something like that.

But here, if you're adventurous enough, you can use a magical pipette to measure liquids.

This thing looks like a handheld 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, so you can operate multiple tubes at the same time.

It is both trouble-free and accurate. You no longer need to be afraid of the monster like Shibao'er who takes the liquid "accurately with just a pinch".

The bad news is that this gadget with the thermofisher stific printed on it costs more than 30,000 yuan each.

Forget it, let’s continue using rubber test tubes...

During the preparation process in collaboration with Shen Yiyun, Li Zheng also got his first glimpse of scientific research.

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

To be precise, they are organic photovoltaic cells, the kind used in solar power stations.

Even laymen know that the difficulty in 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 are efficient but expensive.

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

Therefore, Hu Zengwu's research team 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 that of inorganic cells. By the way, Another 40% cost reduction was achieved.

Today, our country has reached the international leading level in this field, and organic batteries are only one step away from commercial use.

These are scientific researchers. They are just ordinary uncles with thin hair walking on the street.

Only in areas that most people don't understand at all, and in places that they don't know anything about, can they truly shine.

Until their results are delivered to people in a convenient and cheap way, people may not be aware of 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 at the edge of the y-receptor, just to enhance its "conductivity" by a few thousandths.

To put it more bluntly.

The y receptor is probably a ghost thing made up of the 10 large rings in the ring question.

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

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

It is impossible to know how many times Hu Zengwu did it.

And experiments like this are only one of more than a dozen experimental projects of the entire research group.

…

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

She gritted her teeth and glanced at Hu Zengwu, who was immersed in front of the optoelectronic experimental bench, and silently turned off the alarm clock.

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

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

"Well... the closing ceremony will begin soon." Hu Zengwu waved his hand without raising his head, "You go ahead and help me see if I can win the team championship this year."

"Thank you, Teacher Hu!" Shen Yiyun was delighted and quickly pushed Li Zheng and said, "Hurry up, hurry up and clean up..."

"Let's do another set..." Li Zheng wiped his sweat with a flushed face, "I feel btp-ec9 is very promising, I'll work on it more."

"!!!" Shen Yiyun gritted his teeth.

You are jumping to hell!

"Okay, that's it for today. Make the experimental records. I'll test the photovoltaic efficiency of btp-ec9 later." Hu Zengwu was in a rare good mood. He looked up at Li Zheng and smiled, "I've learned about scientific research today, right? ?”

"It's still early to understand. It doesn't even count as a beginner..." Li Zheng scratched his head and said, "I was only excited the first day. I have been doing it for many years. Even if I do it for half a year, I may not be able to improve by one thousandth. I guess I will also suffer. Can’t live.”

"There's no way, that's what real scientific research is." Hu Zengwu shook his head and sighed, "That's why people who are semi-informed prefer physics and mathematics. They always think that they can become Newton or Einstein with a slap on the head, but they don't know the real results. , it’s all worked out bit by bit.”

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

"Okay, pack up and leave." Hu Zengwu turned his head again, waved his hand, and said hesitantly, "Well... my research group... is actually recruiting people recently... although the applicants are graduate students and above... ...But occasionally there are outstanding undergraduate students, and it is not impossible to consider..."

Li Zheng was stunned for a moment, but before he could reply, he first felt Shen Yiyun's burning eyes.

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

No, no, no...this is the call of hell.

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

The two of them changed their clothes in embarrassment, drank two bottles of Nutritional Express, and escaped from the laboratory building. Shen Yiyun gasped and said: "He...he lied...he didn't recruit at all...he just wants your skills." .”

"I think too..." Li Zheng looked at his hands and said, "Then I can't expose myself casually anymore..."

"Anyway... just like a perverted man will covet a girl with a good figure, an old professor will covet a student's skills." Shen Yiyun looked at Li Zheng and said solemnly, "You and Shi Yang are basically the same in our circle. Just like Diao Chan and Xi Shi, they must be careful not to be targeted by professors with evil intentions."

Li Zheng tried hard to imagine, and then...

"vomit……"

"What's wrong?"

"Imagine Shi Baoer wearing Diao Chan clothes and dancing."

"vomit……"

…

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

It was said to be a live broadcast, but it was actually not official. It was live broadcasted by a teacher who was with the team on his mobile phone. Li Zheng also conveniently sent the link to the Dragon Ball group for everyone to spread the word.

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

"Brother, let's never touch chemistry."

"The four major sinkholes of biochemical environmental materials! Really, don't touch any of them."

"Hey, I just didn't accept it back then... It's better now. I've spent three and a half years in college trying to figure out how to change departments."
