Li Zheng already had a foundation, and 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 was a completely different look.

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

Shen Yiyun saw that the teacher was about to get angry, so he hurriedly put down what he was doing and stopped: "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, and I just happened to read the papers of Mr. Hu's research group in recent years, and I know a little bit about photovoltaic research. ”

When Hu Zengwu heard this, his expressionless old face suddenly trembled: "You read the papers of our group while studying under me?"

"Yes. Li Zheng nodded steadily.

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

Hu Zengwu blushed a little.

After all, he didn't teach Li Zheng.

Moreover, will people like Li Zheng really be humble enough to study the papers of this research group?

It's more like ......

Research opponents in all aspects, so it's easy to find faults, right?

However, Li Zheng has already stood up and talked eloquently: "I found out that Mr. Hu has been immersed in the photovoltaic field for more than ten years, researched and iterated more than 30 versions of photovoltaic materials, and led the national scientific research team in this area, from the initial fluorination route, all the way to the current chlorination route, almost every few months can study more optimized designs." It's an honor to have the occasional opportunity to be a part of it. ”

This seat said Hu Zengwu, which made a frightened person.

Is this really Li Zheng?

Transsexualized?

Even Shen Yiyun didn't know what to say.

Li Zheng looked at Shen Yiyun with some dissatisfaction and said: "Senior sister, you too, can be fortunate to join such a dynamic research group, and make outstanding contributions to China's solar power generation industry at the graduate level, how can you still have time to take a vacation?"

"Ah......" Shen Yiyun understood this time.

Good for you, a thin eyebrow and a sharp face, a tooth for a tooth, this is double the reward.

On the other side, Hu Zengwu turned his head sideways and said unwillingly: "Then you should know very well what Yiyun is doing now?"

Li Zheng replied without hesitation: "Well, optimize the receptor molecule Y6 by chlorination, try a variety of different new receptors, and compare their electronuclear transport efficiency. ”

"Hmm......" Hu Zengwu scratched his somewhat burning face, "Then you...... Let's help Yiyun do it together, pay attention to the safety of the experiment, it's hard work. ”

"It's not hard, it's not hard. ”

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

Finally, I was able to touch the top-of-the-line equipment.

He had used a lot of things before, but he didn't expect the scientific research lab to be more advanced.

Take liquid handling as an example, when you compete, you use a dropper and a measuring cup to deal with it, and the highest end is water bath distillation or something.

But here, if you're pressed enough, you can measure liquids with a magic pipette.

It looks like a handheld barcode scanner, and you can adjust how much liquid it takes and how much liquid it puts on the panel, and there is a row of droppers underneath that allows you to operate multiple tubes at the same time.

It's both trouble-free and accurate, and you don't have to be afraid of monsters like Bao'er who take the liquid "accurately".

The bad news is that this gadget with ThermoFisher Scientific on it costs more than 30,000 yuan each.

Forget it, let's continue with rubber test tubes......

In the process of collaborative preparation with Shen Yiyun, Li Zheng can be regarded as the first glimpse of scientific research.

His previous words were not blind beeps, Hu Zengwu's team has indeed engaged in photovoltaic research for ten years.

To be exact, it is organic photovoltaic cells, the kind used in solar power plants.

Even the layman knows 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 priorities.

For a long time, the mainstream of the market has been inorganic cells based on silicon-based cells, which are efficient but expensive.

Organic batteries, on the other hand, only exist in the laboratory, and 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 group locked in the direction of "organic photovoltaic cells" ten years ago, cooperated with many universities and science centers, and spent 10 years to increase the efficiency of organic cells to 70% of inorganic, and by the way, reduce the cost by 40%.

Today, China has been at the international leading level in this field, and organic batteries are only one step away from commercialization.

This is the scientific researchers, they walk on the street, just an ordinary uncle with sparse hair.

It is only in areas that most people do not understand at all, in places that they do not know at all, that they really shine.

Until their results are delivered to people in a convenient and cheap way, people may not even be aware of their existence.

If solar power generation can be understood somewhat, 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 that puts together the big rings in the title of 10 circumferential rings.

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

Experiments like this are only one of a dozen or so experimental projects in the entire research group.

......

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

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

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

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

"Hmm...... The closing ceremony is about to begin. Hu Zengwu didn't raise his head, but waved his hand, "Go ahead, 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 and said, "Quickly clean up, quickly clean up ......"

"Let's make another group...... Li Zheng wiped his sweat with a flushed face, "I feel that the BTP-eC9 is very promising, a little more." ”

"!!" Shen Yiyun gritted his teeth.

You're jumping into hell!

"Okay, that's all for today, do a good job of recording the experiment, BTP-eC9 I'll wait to test the photovoltaic efficiency. 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, right?"

"It's still early to understand, it's not a ...... to get started," Li Zheng scratched his head and said, "I'm excited for the first day, I really want to do it for many months as an adult, and I may not be able to improve by one thousandth for half a year, and I guess I can't stand it." ”

"No way, that's what real scientific research is. Hu Zengwu shook his head and sighed, "So people who don't understand it prefer physics and mathematics, and always think that they will become Newton and Einstein with a pat on their heads, but they don't know that the real results are boiled out bit by bit." ”

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

"Alright, pack up and go. Hu Zengwu turned his head sideways again, waved his hand, and said hesitantly, "Hmm...... My research group...... Recently, there have been recruitment...... Although it is written about graduate students and above...... However, there are occasional outstanding undergraduates, and it is not impossible to consider ......"

Li Zheng was stunned for a moment, and before he could reply, he first felt Shen Yiyun's scorching gaze.

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

Don't, don't...... This is the call of hell.

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

The two of them changed their clothes in embarrassment, smoked two bottles of nutrition express, and escaped all the way out of the experimental building, before Shen Yiyun panted and said, "He...... He lied...... There is no recruitment at all...... He's the one who covets your craft. ”

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

"Anyway...... Just as a man will be hungry for a girl with a good figure, an old professor will also be hungry for the student's craft. Shen Yiyun looked at Li Zheng and said solemnly, "You and Shi Yang are basically equal to Diao Chan and Xi Shi in our circle, but you must be careful not to be targeted by ill-intentioned professors." ”

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

"Vomit ......"

"What's wrong?"

"Imagine Spoll dancing in a sable outfit. ”

"Vomit ......"

......

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

said that it was a live broadcast, but it was not official, but a certain teacher with the team himself used his mobile phone to broadcast live, and Li Zheng also sent the link to the Dragon Ball group for everyone to spread it.

After everyone got to know each other, before the awards began, the two eldest brothers couldn't wait to start persuading them to quit.

"Brother, let's not touch chemistry. ”

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

"Hey, I just didn't accept it back then...... Well, now I've been in college for three years, and I've been trying to change departments for two and a half years. ”

"Can you imagine...... When you were in school, you were pouring those liquids in the lab every day...... You're retired, you're still in the lab, you're still pouring those liquids!"

"Some pouring is a good thing, do you know how many people are not even qualified to pour liquid?"

"Alas, the girl may still take advantage of it, many teachers like to accept girls, not for experiments, but mainly to motivate the men in the laboratory, each person can increase the efficiency by 15%, this girl is not in vain. No, no...... It doesn't mean anything else, Senior Sister Shen, you have a level...... NOT A TOOL BUFF. ”

After Li Zheng deeply accepted their persuasion, he saw that the closing ceremony on the Pad screen was about to start, so he casually asked, "Have the two senior brothers also participated in ICHO?"

"Nope. The graduate student boss waved his hand and said, "It's just a national bank." ”

"I'm a province one. The undergraduate boss smiled, "Shonan Province one." ”

The graduate student boss hurriedly gave up his hand: "It turns out that you are from Shonan, that is better than my country's silver." ”

"Hey......" the undergraduate guy sighed, "It's too difficult, Shonan is really too difficult, and it was hard to come out with a pleasing god, but it turned out to be that kind of result last year...... Everyone scolded us for Shonan...... Alas!"

"Don't panic, I will be able to take it back this year. After patting the undergraduates, the graduate student said to Li Zheng, "Actually, we also think there is a problem, obviously we all suffered losses last year, how can we pay one province and one person this year." Li Zheng, your level is here, go with Shi Yang, can this champion still run?"

"Hey, don't mention it, don't mention it. Li Zheng pursed his lips and smiled, "At that time, it was considered a bit of a fuss, it was very immature." ”

"Sooner or later, you're just not in time for the good times, brother. The undergraduate student also looked at Li Zheng with great regret, "Anyway, I don't plan to do chemistry, so don't think about it." ”

"I don't think about it, I don't think about it, I just think about the team championship. Li Zheng replied with a smile.

After a while, the closing ceremony officially began, and the bigwigs of the Institute of Internationalization began to give speeches, and a few people sitting there could actually understand the hard work, but they were not in the mood to listen, only thinking about the results.

The live barrage is very powerful.

[Zhuo: I'll translate. 】

[Zhuo: I'm very happy that after 50 years, ICHO is back in Prague ......]

However, no one read his translation.

[Give Shi Baoer a shot, teacher!]

[What about Wei Dongyang?]

[Come on! China will win!]

Although there are only about 100 people in the live broadcast room, these long-lost names and atmospheres still substitute Li Zheng into it.

It's just a few months ago, but there is a feeling of looking back on my youth and meeting my old comrades-in-arms again.

After a few unknown bigwigs gave speeches for more than half an hour, they finally arrived at the only meaningful award ceremony.

The scary thing is that this is awarded starting with the bronze medal.

There are a total of 300 participants, of which the part ranked 100-200 is basically the bronze medal.

In a group of 15 people, each holding their own national flag, they came to the stage to receive the award.

It's a long and painful process.

Needless to say, the torment is mainly in the search for the five-star red flag.

If the red flag does not appear, then it can be relieved......

In case one appears, it's troublesome......

After staying up for more than ten minutes, I got the silver medal.

People are also becoming more and more worried.

The barrage is also a big string of [don't] [don't] [don't].

Everyone knows their own level, and it is basically a shame not to win a gold medal.

Finally!

An unkempt man came on.

Pulling the national flag, he stood in the middle with a sad face on his face, and he was crying until the chairman hung up the silver medal for him.

[Wei Dongyang, you brother!]

[Haha!Pull the crotch!Pull the crotch!]

[The silver medal is speechless in the face of Jiangdong's father!]

The live broadcast teacher also seems to know how to control the rhythm, and gave Zhou Yi a shot at the right time when Wei Dongyang received the award.

I saw Zhou Yi's face full of gloom, and he seemed to have an urge to cut people.

【Dangerous !!】

[Brother, you're going to be in a ring. 】

[Zhou Chenghuan is thinking about how to synthesize corpse water. 】

Fortunately, this situation did not last long.

Soon, it was the turn of the gold medal.

Everyone relaxed a little.

Looking at it this way, there is a high probability of one silver and three golds, which is still possible.

Finally, in the penultimate group, when the 4-10 awards were awarded, everyone's hanging hearts were basically put down.

The other two members of the national team won the sixth and seventh places respectively, and won two consecutive gold medals.

【T !!】

【Chinese team awesome !!】

[Shi Baoer!! Shi Baoer's mother loves you!!

The live broadcast teacher took Zhou Yi with his hand.

At this time, I saw him wipe his sweat, turned his head and said to the teacher, "You scared me to death...... The rest depends on Shi Yang. Huh, what about live streaming?...... I shouldn't have sweared......"

[Hahaha!]

[Zhou Chenghuan is awesome!]

[Prague's large-scale ring-forming site. 】

Under the watchful eye, finally, it reached the top three.

The host stood in front of the stage, wiped his sweat, took a deep breath and announced-

“Rank3：Raymond Eugene Bahng，Korea！”

In the applause, Bahng's results were reflected on the big screen -

Total practical (experimental): 33.96

Total theory: 54.87

Total: 88.83

A South Korean brother with a standard hair that blocked his head shook his head and smiled on the stage, shook hands with the chairman, and stood in the third place position and pulled up the national flag.

The moderator went on to announce -

“Rank2！”

At this moment, everyone's hearts were completely lifted.

Even the barrage is gone.

Everyone had the same mantra in their hearts.

Don't be Shi Yang...... Don't be Shi Yang......

I saw the host's eyebrows raised, and he raised his hand excitedly-

“Aleksei Konoplev Ruuuuussian Federation！”

This time, the applause was noticeably more intense.

A man with Russian glasses with super long hair and a super high hairline got up with a smile and trotted towards the high platform.

[Spoa's mother loves you!!]

[I fuck my hairy brother, this look is too sassy!]

[The demon is still a Ruuuuussia demon.] 】

Soon, the elder brother also completed the process and came to the stage to raise his national flag happily.

His results were then reflected on the big screen.

Total practical：32.52

Total theory：57.92

Total：90.44

After the elder brother stood firm, the host took a long breath and spoke with a smile on his face-

“Champion！”

“Yang Shi！China！”

“Celebrating China！Celebrating Shi！”

I saw Shi Yang jump up, swing his fist three times in a row, and then hug Zhou Yi for the first time, and cried as soon as he pounced.

Zhou Yi's eyes were also a little sour, and he kept patting Shi Yang, but the applause was too loud to hear what he said.

After coaxing for a while, Shi Yang finally wiped his eyes and stepped onto the podium.

I haven't seen him for many days, and he is wearing a suit......

It's even more bloated than ever.

The Russian brother also pinched his arm and joked.

Shi Yang looked serious, pulled the national flag straight, tears poured out, and he couldn't say a word.

Behind him, are his achievements.

Total practical：40.00

Total theory：58.82

Total：98.82

The barrage was completely boiling.

[Spoyer's mother loves you to death!!]

[The man who has a perfect score for the experiment eternity!!]

【Light of Chemistry!!Shi Yang!!】

【Awesome, awesome!!】

Even Li Zheng and his entourage, who were watching the live broadcast in the water bar, jumped up.

"ICHO experiments are all full ???"

"I'm afraid I'm scared of the judges!"

"It's okay, it's really okay, and Nobel can't say it. ”

"Earn a big face!

Shi Yang himself didn't care at all, he just pursed his mouth and cried, which was very cute.

Then, the chairman hung up the gold medals for the three people, and the host took the microphone to start the interview from the third place.

Because it was an international event, everyone answered in English.

The Korean brother thanked him and said that this was his most exciting moment.

The Russian brother said that he thought the question would be difficult, so he prepared a lot of tricky things for it, but unfortunately they didn't use it.

When interviewing Shi Yang, he still had a serious face and said in English that he was not very proficient in.

"Thank you to the organizers, thank you to the Chinese Chemical Society. ”

"Thank you for organizing such a wonderful chemistry event. ”

"I know everyone is in a hurry to get to dinner...... But I might ...... It's still going to take up a little bit of everyone's time. ”

"I don't know, you don't know my motherland. ”

"In my home country, there are thousands of young people who are interested in chemistry. ”

"But it's just the four of us standing here. ”

"It's even more regrettable that there are some people who are no less than me in level and strength because of some outdated rules. ”

"To this day, I am saddened by this. ”

"I've tried protesting, I've tried organizing grievances, I've tried to change this in all sorts of ways. ”

"Now, I'm going to make a final effort on this. ”

"Here, in my personal capacity, I give up this gold medal. ”

"Leave it to someone who deserves it better than I am. ”

After saying that, Shi Yang suddenly turned around and threw off his bloated suit-

A blue-and-white school uniform was revealed.

Then, turn around and turn the back of the camera onwards.

There's a name clearly printed on it—

【Li Zheng】

【Li Zheng】
