In the morning,

Xu Mang, Xiao Tao and Xiao Liu did nothing, the three of them sat together knocking melon seeds, drinking a pot of flower tea, talking from the origin of the universe to the destruction of the world, analyzing the difference between family, friendship and love, and analyzing the fragility of human nature by the way.

"Professor Xu?"

"In the end, we're ... What are you doing?" Xiao Tao, a girl with glasses, asked curiously: "We've been talking all morning, and we're going to finish drinking the flower tea, and I don't even know what the project is... When Mr. Yang found the two of us, he said that it was a very powerful project. ”

"That's right!"

"Professor Xu... Really don't knock it, melon seeds are easy to catch fire. Xiao Liu said seriously: "And if Mr. Yang sees that Xiao Tao and I don't work, we will leave the next day... Professor Xu, let's start in the afternoon. ”

Hearing Xiao Yanagi's words, Xu Mang said with disdain: "I said that you are all ... is nearly a round older than Xiao Man, and he is afraid of becoming such a coward, which is really useless... Don't look at me like this, I'm the emperor at home!"

“...”

“...”

Finished

Professor Xu is floating!

Xiao Tao and Xiao Liu don't believe that Xu Mang is the emperor at home, with Yang Xiaoman's appearance in the company, it is estimated that the family is also a female devil, how can they obey Professor Xu Mang's words in every way, unless there is only one possibility, Professor Xu Mang is dreaming.

"Oops!"

"Trust me... What I'm saying is true. Xu Mang said seriously: "You Mr. Yang... I asked her to go east, she didn't dare to go west, I asked her to go west, she didn't dare to go east, that's how manly she is. ”

"Ahem!"

suddenly

A crisp cough came from the door, almost scaring Xu Mang to death.

Glancing back, Xiao Man looked at himself with a dark face, Xu Mang couldn't help but smile embarrassedly, and reprimanded Xiao Tao and Xiao Liu in front of him: "What nonsense? How can a man who loves his wife so much do such a thing? This kind of thing is not allowed to be mentioned in the future!"

Words fall,

Xu Mang hurriedly got up and walked to Xiao Man's side, hugged the angry airport, and asked with a smile, "Wife, let's go out to eat?"

Looking at the backs of Xu Mang and Yang Xiaoman drifting apart, Xiao Tao and Xiao Liu glanced at each other, and saw the consternation in each other's eyes. Professor Xu, this is a special person? The black cauldron came over for no reason...

"It's over!"

"It seems that we are not working hard, and Professor Xu may be blowing the pillow wind in Mr. Yang's ears. Xiao Tao said with a desperate face: "This is still... Is it still the upright Professor Xu in my fantasy?"

“...”

"Don't do more... I think it could have been an accident. Xiao Liu thought for a while, and said calmly: "Actually, I can understand why Professor Xu is like this, it is estimated that he was bullied by our Mr. Yang at home, and he will have to save face if he is a person." ”

At this point,

Silence is better than sound.

...

"Humph!"

"I know to brag all day long. Yang Xiaoman glanced at Xu Mang, and said angrily: "Can you put away your machismo in front of others?

"I'm just talking about it. Xu Mang smiled and said: "Xiaoman, wife, dear, if the progress of perovskite film is relatively fast, what do you plan to do in the first step?

Yang Xiaoman nodded and said seriously: "But before that, I need you to publish research reports in important journals, but if you leave the core technology, we will monopolize the core technology and make the most money with the least resources." ”

Similar to before, it is still the core technology route, Xu Mang agrees with Xiaoman's approach, such as photoresist materials, although there are not a few in the world that can produce photoresist materials, but there are only a few top preparations, and at the top of the pyramid is Xiaoman's company.

However, she only sells one thing, the adhesive of the photoresist material, which is known as the golden liquid all over the world, and the price is high, and there is often no supply.

"Hmm!"

"Anyway, how about the ultra-thin semiconductor film?" asked Xu Mang curiously.

"Hee-hee!"

"It's basically a monopoly. Yang Xiaoman said with a smile: "Do you know how much we earn a year? Although it is not even one-fifth of Dad's, it is already very powerful, and we only have two companies." ”

Xu Mang nodded, he didn't care about this, anyway, no matter how much money he made, he could only spend so much.

After lunch,

Xu Mang returned to the laboratory and found that Xiao Tao and Xiao Liu were already there.

"So early?" Xu Mang asked curiously, "Don't you have a lunch break?"

“...”

“...”

Tao and Yanagi shook their heads.

Xu Mang hit a hatchet, and said helplessly: "Why don't you study it yourself first? I'm a little tired... Need to make up for a nap. ”

Words fall,

He took out a stack of research reports in English from his handbag and placed them on the table.

“？？？”

“？？？”

Seeing Xu Mang lying on the table sleeping, the two were completely speechless for a while.

it...

This... What's going on here?

At last

The two could only compromise and recognize the facts in front of them, it is estimated that Professor Xu went to bed very late yesterday, at this time Xiao Tao took the research report that Xu Mang put on the table, and read it with his colleagues, and the content made the two of them have a lot of pressure.

All in English!

Of course, there is nothing wrong with this, but there are some technical words that I can't read.

"Huh?"

"It's... This seems to be a thin film of perovskite oxides, strontium titanate and bismuth ferrate. Koyanagi said solemnly: "This... We want to make this kind of perovskite monolayer film? There seems to be some difficulty, I heard that it is difficult to succeed. ”

"Hmm!"

"I don't know where Professor Xu got the information, but I'm sure... It's impossible. Xiao Tao, the glasses girl, said: "At most, ten preparations can be completed at most." ”

What to do?

It's an impossible task.

"Professor Xu?"

"Professor Xu... Don't sleep, wake up!" Xiao Tao hurriedly pushed Xu Mang, seeing that his eyes were hazy, with a hint of confusion on his face, he asked curiously: "We... We want to study thin films of perovskite oxides, strontium titanate and bismuth ferrate?"

“...”

"Hmm!" Xu Mang nodded and asked in a daze, "Is there any problem?"

Suddenly,

The two fell into silence, it seems that Professor Xu didn't know the difficulties he encountered!

Is there a problem?

Of course there is a problem!

"Professor Xu?"

"In the world, almost no one can produce perovskite oxide films 100%, and the success rate in the United States is less than 1 in 10. Xiao Tao said seriously: "The cost of preparing a perovskite oxide film is very, very high, and it cannot be put into the commercial field at all. ”

"Oh..."

Xu Mang sat on the chair with a cute face, his brain had not yet fully received Xiao Tao's information, and he needed to think for a while.

Looking at Xu Mang, who was not in the state at all, Xiao Tao and Xiao Liu were very busy and anxious, they didn't want to waste their precious time in an impossible project, if they stayed in this project without doing anything, although Yang would always see Professor Xu's face and would not fire themselves, but... The income has decreased too much.

finally

Xu Mang sobered up, looked at the two people in front of him, and asked with a smile: "America is America, we are us, and they can't represent us, my goal is to find a way to prepare perovskite oxide films 100%. ”

“？？？”

“？？？”

Lose your marbles?

This... What kind of concept is this?

"Professor Xu?"

"According to the theoretical limits, if the film is too thin, the lattice collapses, making it impossible to fabricate. Koyanagi said seriously, "Now... The world does not know if there is a need for a minimum thickness to keep the lattice structure stable. ”

"This..."

"This question has been bothering researchers of 2D materials all over the world, for a long, long time... It's been so long that it's almost forgotten. Koyanagi continued, "Professor Xu... In order to break through the perovskite oxide film dilemma, we must first solve the limit theory. ”

Limit theory?

Not to mention... It is necessary to break through the theoretical dilemma.

"You've all seen it, right?" Xu Mang asked curiously, "That's it... That's all for today, and we'll continue tomorrow. ”

soon

The two saw Xu Mang leave the laboratory with the materials, watching his back disappear from their field of vision, Xiao Tao and Xiao Liu sighed.

"Did you notice Professor Xu's eyes just now?" Xiao Tao said: "A little serious, a little stubborn, and... There's a little bit of madness, yes, yes, yes... It's that hysterical madness!"

“...”

"What's the use of being crazy?" Koyanagi said helplessly, "The limit theory limits the framework of perovskite oxide films, and unless Professor Xu can break through this limit, I don't think he can succeed." ”

Pushing the limits,

How many outstanding researchers of 2D materials in the world are working hard for this, and how many people are in trouble.

"Actually..."

"I'm looking forward to it. The glasses girl Xiao Tao said seriously: "Professor Xu is a man who often creates miracles, I don't know... Tomorrow morning, will it bring us a miracle. ”

"Oops!"

"I know you're Professor Xu's little fan girl, but you still have to follow the basic laws and scientific consciousness for one night... Do you think it's possible to break through the limit theory in one night?" Koyanagi said with a dark face: "One month! two weeks at the earliest, one month at the slower." ”

meanwhile

Xu Mang took his handbag and came to Xiao Man's office, pushed the door and saw that the violent airport was working, not to mention... The meticulous Xiaoman is beautiful.

"It's over?"

"Hmm. ”

"Let's do it in the study in the evening. Xu Mang smiled: "I need a closed and quiet dark space, only a table lamp is enough, so that I can have the idea of solving the problem." ”

Although Yang Xiaoman was very unhappy with Xu Mang's plan to work again at night, there was no way... During the day, this guy doesn't seem to have much inspiration, and that can only consume precious night time, alas... Tonight is another lonely night.

...

night

So peaceful,

Xu Mang came to his study, took out the materials from his handbag, flipped through them briefly, and then silently picked up the pen in his hand.

"Let's get started!"

......
