The method used by the aliens is similar to the chemical vapor precipitation CVD method to obtain high-quality graphene. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

The specific process of this method is to pass hydrocarbon methane, ethanol and other gases into the surface of the metal substrate Cu and Ni heated at high temperature, and the reaction lasts for a certain period of time and then cools, and several or single layers of graphene will be formed on the surface of the substrate during the cooling process.

In this process, there are two parts: the dissolution of carbon atoms on the substrate and the diffusion and growth.

This method is similar to the metal catalytic epitaxial growth method, which has the advantage that it can be carried out at a lower temperature, which can reduce the energy consumption in the preparation process, and the graphene and the substrate can be easily separated by chemical corrosion metal method, which is conducive to the subsequent processing of graphene.

However, this method has a disadvantage, the thickness of the prepared graphene is difficult to control, and in the precipitation process, only a small part of the available carbon is converted into graphene, and the conversion process is still very complicated.

In the database of Little Babbling, the aliens have obviously made great improvements to this method, and also listed more than a dozen ways to control the quality and thickness.

Xie Dong continued to look at it, and soon found that the aliens' research on energy blocks had reached an unbelievable level, and this small energy block even contained a miniature nuclear fusion reactor, no wonder, they needed helium-3 and ghost particles.

These small articles are of immeasurable value, the more I read it, the more frightened Xie Dong became, if Xiao Babbling was not a character who existed in the computer, he would want to hug her and kiss her fiercely, it was really too valuable - in her database, there was also a complete set of equipment production methods.

It's almost like a textbook.

Holding back the excitement in his heart, and remembering every character and schematic picture in it hungrily, Xie Dong knew that he was busy.

Next, it is estimated that it is time to spend money again, and it may cost tens of millions of dollars just to manufacture research equipment.

However, there is no urgency in this matter.

After all, it's useless to be in a hurry, just study it slowly in the future.

At this time, the sky outside had already brightened, and the night passed like this, Xie Dong took a deep breath, went out to wash his face and brush his teeth, and planned to go back to school today.

Although it doesn't make much sense for him to go to school now, being idle is also idle, and it's good to go there and enjoy life.

Compared with high-tech research, he is more concerned about whether his life is comfortable.

The little black cat is still teasing and babbling.

This artificial intelligence has a lot of secrets, and if necessary, Xie Dong will find out all the things on it.

At this time, my parents had already gotten up and were making breakfast in the kitchen, and they looked quite strange when they saw him get up so early today.

"Up?"

"Hmm!"

"Then hurry up and brush your teeth and eat!"

Dad was holding a newspaper in his hand to read, it was estimated that it was sent this morning, Xie Dong glanced over, only to see the headline on the newspaper, with a few big words written in red handwriting: "Skynet appears, countdown to the destruction of the human world?" 》。

These things are already clichés, there is nothing worth paying attention to, chatted casually with his parents, and then after breakfast, Xie Dong went out with his schoolbag.

Today, Mu Cheng will send Mu Lingshan to school, so Xie Dong can also take a trip without having to let his private driver make a trip.

He walked to the door of Mu Lingshan's house, only to see Mu Lingshan's girl wrapped like a rice dumpling, wearing a thick purple down jacket, with a white spinning coat on her head, waiting for him while exhaling cold air.

"Coming?"

"Hmm!"

"Then let's go, I'm going to be late!" Mu Lingshan smiled slightly, then grabbed his hand and pulled the car door.

Mu Cheng glanced back at them, and saw that they looked like you and me, and suddenly smiled: "It's good to come, but I still have to say something, it's good that you have a good relationship, but don't forget, you are still in school, don't do that!" ”

"What's that? What's the matter? Mu Lingshan looked up suspiciously and asked.

Mu Cheng smiled slightly: "What else is going on?" In short, you have to be cautious, you have to have strong self-control, but you can't steal the forbidden fruit for me. Otherwise, I will not spare you! ”

"Forbidden...... Forbidden fruit? Mu Lingshan's eyes widened, and she immediately understood, her face quickly turned crimson, and she said shyly: "Dad, what nonsense are you talking about?" What forbidden fruit? ”

Mu Cheng laughed: "Haha, there is no best!" Am I not afraid that you are still young, and you can't help it, and you can't control it? After a few more words, don't blame it. ”

Mu Lingshan only felt blushing, glanced back at Xie Dong, and saw that he was looking at him with a smile on his face, his expression was meaningful.

Her heart throbbed, and she couldn't help but reach out and punch him in the shoulder, bit her lip and said, "Badass! ”

Xie Dong saw that she looked like she had an apricot face and peach cheeks, and he couldn't help laughing, and said in a low voice: "You're not right, you beat again for no reason, but you have to be punished?" ”

Mu Lingshan was stunned: "Huh? ”

Before she could react, she saw Xie Dong suddenly lean towards her, and then smacked her blown-up right cheek with lightning speed.

Suddenly, there was a familiar heat and slippery, Mu Lingshan's heart was shocked, and she reacted instantly, and looked at him with wide eyes, her face turned red at a speed visible to the naked eye, and in an instant, it spread to her neck.

She almost subconsciously glanced at her father in front of her, but Mu Cheng pretended not to see anything, a strange smile appeared on the corner of her mouth, and she pretended to drive.

Seeing this, Mu Lingshan only felt that her heart was about to jump to the dumb door, and she couldn't stop thumping, she suddenly felt embarrassed, she didn't know what to do, she quickly lowered her head, blushed, and her big eyes were spinning rapidly.

The ears are already red.

In any case, doing this kind of thing in front of your own parents is indeed a bit exciting and a little nervous.

I've done it before, but it's obviously not in front of my parents. Although his father has always been more open-minded, it is one thing to be open-minded, and it is another thing to be found out - he is too bold.

Xie Dong saw her blushing, but he didn't dare to look up, looking like a shy little daughter-in-law, he thought it was too interesting.

This girl's face is much thinner than expected.

He smiled, reached over, gently pulled her little hand over, and then held it firmly.

Mu Lingshan was stunned for a moment, and quickly struggled, but in the end, he didn't break free, let him hold it, and his expression showed a hint of strangeness.

Due to the cold weather, the girl's hands are a little cold, but they feel like they are boneless and very soft to hold, and the amazing touch makes people sigh in their hearts.

Recalling the darkness, coldness, and panic he experienced in the universe last night, Xie Dong knew that only this girl could make him heal quickly.

She is the kind of pure natural healing girl, with the attribute of healing +100, a glance and a smile, all of which are touching and full of warmth.

Now he is blushing and looking ashamed, not to mention, it is not too perfect.

Xie Dong has always felt that she must be the greatest gift God has given him in this life.

"Let go of me!"

"Don't let it go!"

Mu Lingshan glanced up at him with disgust, and suddenly lowered her voice and said, "Shameless!" ”

"Huh!" When Xie Dong heard this, he couldn't help laughing, reached out and pinched her pretty face, which was still a little baby fat, and didn't speak.

He didn't rest all night last night, he felt a little tired, and he estimated that he would need to sleep for a while after arriving at school.

Mu Lingshan glanced at him, smiled slightly, and didn't say more.

Since he was unwilling to let go, he simply let him hold it, and there was nothing to lose by holding it anyway.

It's just that Mu Cheng, who was driving, saw that they didn't speak, and suddenly turned around and glanced at them, and the strange look that seemed to be smiling made her feel very blushing.

Alas, Dad, I must have just found out.

What a shame! (To be continued.) )
