It's hard!

Xu Mang found that the surface of the waste wood that had been soaked in acid was very hard.

Suddenly,

The curiosity was attracted by this strange phenomenon, why is the surface of the waste material so hard after being soaked in acid?

Do you want to soak it again?

What if the bubble is soft?

Driven by curiosity and boldness, Xu Mang secretly threw this piece of extremely hard waste wood back into a glass filled with acid solution, and for about a few seconds, he secretly took it out again.

And then... Xu Mang was completely confused.

Alas...

It's miserable.

I can't go back, it seems... It doesn't seem to corrode.

What to do?

Xu Mang glanced at the group members who were working hard, and was about to speak, when a female member shouted, "Xu Mang... Order a takeout for us, uh... I'm going to eat braised chicken. ”

With the first one taking the lead, the remaining four reported the takeout they wanted to eat, and then the miserable Xu Mang ordered them one by one, and the more he ordered, the more annoyed he became.

Nima...

It's a hassle.

But trouble is trouble, Xu Mang still silently ordered takeout, and after ordering, he went downstairs to wait for takeout.

soon

Hurriedly went upstairs with takeaways, came to the laboratory and shouted at the five people: "Come on, come on, I'll rely on... I'm a graduate student in a dual department, helping you order takeout, how big is your heart?"

Hearing Xu Mang's complaint, the five of them just smiled, what else could they do?

Cold salad.

"Ahem..."

"You're bored anyway, aren't you? One of the members smiled and said, "Xu Mang, I heard that you have a very beautiful girlfriend in the School of Economics? What's Yang Xiaoman's name, isn't it?"

"That's right. ”

"What's wrong?" Xu Mang asked curiously, "Huh... You're all single dogs?"

“？？？”

“？？？”

“？？？”

it!

What the hell do you know how to chat?

Five people are so angry.

"Huh?"

"I said Xu Mang... You can't do whatever you want if you have a girlfriend. A male compatriot present said, "It's great to have a girlfriend?

Xu Mang smiled, he was angry when he ordered takeout for these people, but now he finally found an opportunity to fight back, and retorted on the spot: "I'm sorry... It really doesn't matter if you have a girlfriend, you don't have a girlfriend or not, and you don't understand the happiness of those of us who have girlfriends. ”

“...”

“...”

“...”

No way!

It turns out that the legendary Xu Mang is so cheap?

The five of them looked at Xu Mang's embarrassed expression, and they couldn't wait to go up with a punch.

This guy,

It's not human at all.

"Anyway..."

"How is my girlfriend?" asked Xu Mang curiously.

"Nothing. ”

"There is a photo of your girlfriend on Weibo, and then a group of people who eat melons chose your girlfriend as a talented and beautiful female scholar. The buddy said, "You may be in danger if you go on like this, there are so many young talents, maybe there are one or two better than you, fair lady... Isn't that right?"

"What?"

"A young talent better than me?" Xu Mang was stunned for a moment, and asked curiously, "Brother... It's not that I'm very narcissistic, and there is no one who can be more handsome than me in my heart. ”

hehe

You're thinking about fart!

The five of them ate takeout and sneered at Xu Mang.

Before I did it,

If others question their handsomeness, Xu Mang will definitely be a bar spirit, and have a good bar with them, now with the change of identity, Xu Mang's mood has also changed, and the appearance of this thing is the same, but the interesting soul is unique.

Your soul is not just fun, it's even fun with a little skin.

Speaking of Xiao Man...

Going to see her tomorrow morning?

"Huh?"

"You girls have come to relatives, do you want others to take care of them?" Xu Mang asked, "What... Is it that when you come to a relative, your mood will be particularly impetuous, and then you can't wait to find someone to beat you to death?"

"That's right. ”

"Girl... There are a few days a month, and you'd better not mess with them, they won't beat you to death!" said one of the girls present, "Why are you suddenly asking this question?"

"Curious. ”

"Pure curiosity. Xu Mang said: "Then come to relatives, what is that, what should a boy do?"

"How do I know!"

"I don't have a boyfriend again!" The girl glanced at her and said angrily: "Xu Mang, you did it on purpose, right?

Xu Mang: Embarrassed

Also aristocratic?

Cut!

"How is it possible!" Xu Mang said with a righteous face: "What should you do, for example, you are now a relative, what do you need your boyfriend to do?"

"Think about it..."

Words fall,

The girl tilted her head and began to think, and soon said: "Well, if I come to a relative, I want him to be by my side all the time, hand me a glass of warm water when I am thirsty, bring a hot meal to my mouth when I am hungry, tell me fairy tales when I am tired, in short, just accompany me." ”

"See you tomorrow!"

Words fall,

Xu Mang ran away.

...

In order to help the Department of Materials complete the so-called research and development of the latest materials, Director Liu helped Xu Mang apply for a room in the dormitory of the department, but at this time he did not return to his dormitory, but brought a thermos cup with Ejiao red date syrup in it and went to Xiaoman's dormitory.

Of course

His satchel contained not only a thermos cup, but also a physics and chemistry book, as well as a piece of waste material that he had broken down.

"Hey, hey..."

"Dear Queen?" Xu Mang saw Yang Xiaoman with a gloomy face, and his trademark cheap smile appeared on his face: "Alas... I brought you Ejiao red date syrup. ”

Originally, Yang Xiaoman was angry when he saw your Xu Mang's shy, but after hearing his words, this anger disappeared, he actually... Suddenly I got the hang of it.

"Don't drink it!"

Yang Xiaoman lay on his bed and said expressionlessly: "I don't need to replenish blood." ”

"Okay, okay. Xu Mang smiled: "You don't need to replenish your blood, it's good to replenish your body, this is me... Belch... I borrowed the school cafeteria and boiled it up by myself for three hours. ”

Cut!

Stay up for three hours?

What about bluffing little girls?

However...

Soon, Yang Xiaoman was successfully bluffed by Xu Mang.

Half an hour later,

"Ah~"

Yang Xiaoman opened his mouth happily: "I still have to take a sip." ”

"Oh. ”

"Anyway, this is the last bite. Xu Mang poured the Ejiao red date syrup in the thermos cup on the soup spoon, and then carefully handed it to Xiao Man's mouth.

In fact...

Yang Xiaoman is not interested in this Ejiao red date sugar water at all, what she likes is the feeling of Xu Mang taking care of herself.

It would be nice if relatives came every day,

In this way, you can enjoy the care of this idiot every day, or the kind that takes care of everything.

No way!

In this way, you will lose too much blood and die.

"Huh?"

"Later... Can you come to my dormitory for one day a week?" Yang Xiaoman asked shyly, "Okay?"

"Okay, okay!"

"How are you feeling now?" Xu Mang put the thermos cup back in his satchel and asked curiously, "Anyway, have you been on Weibo headlines recently?"

"Huh?"

"I..." Yang Xiaoman was stunned for a moment, she originally planned to hide this matter, but it turned out that she couldn't hide it at all, because the power of netizens was too strong, and now it is still in the top ten of the popularity list.

And the reason why Xiao Man wanted to hide it was because he was afraid that Xu Mang would be cranky.

"I'm weird... You're a..."The short and flat words behind Xu Mang swallowed back, and smiled helplessly: "Isn't it?"

"It's you!"

"Old lady, I'm so attractive, the whole world is blind to you!" Yang Xiaoman, who originally had a deep sense of guilt, disappeared in an instant, and said resentfully: "Let me tell you, my mother's current suitor is an imposing group, you have to be tight on me, otherwise you will become a single dog in minutes." ”

hehe

Cut!

Is it a joke to be beautiful in the prosperous world?

Xu Mang didn't care about this at all, silently found a chair, put it next to Xiao Man's bed, and then took out a chemistry book and carefully looked at the contents inside.

During the summer vacation,

Xu Mang had already triggered the chemical skill, and the chemical skill value at this time was not very much, barely enough for 10,000.

How to say,

Chemistry level after junior high school graduation.

"Hello?"

"Aren't you here to accompany me?" Yang Xiaoman lay on the bed and looked at him resentfully: "Put down the book and chat with me!"

"Oh..."

Xu Mang felt that he was also a little excessive, obviously came to accompany Xiao Man, but he went to study in a blink of an eye.

Yang Xiaoman: (# ̄~ ̄#)

Very angry!

It's really infuriating!

When I wasn't together before, why didn't I love to study, but now that the two of us are together, I suddenly fall in love with learning?

Deliberately, right?

Why did my wife become a catalyst for his diligence and eagerness to learn?

"What did you say during the day?"

"You were kidnapped by the material department?" Yang Xiaoman asked curiously, "What's the situation?"

"Don't mention it!"

"I've been caught. Xu Mang sighed: "Let me develop what phase change materials, I know a hammer phase change." ”

"Vanadium dioxide?" Yang Xiaoman asked.

"Huh?!"

"How do you know?" Xu Mang looked at Xiao Man in surprise.

At this point,

A hint of arrogance appeared on Yang Xiaoman's face: "I am recognized on Weibo as a youthful invincible and super beautiful female scholar!"

"Then do you know what the situation of this vanadium dioxide is?" asked Xu Mang.

"Want to know?"

"Hmm!"

"Look at how you behave. Yang Xiaoman said proudly: "Let's start." ”

Xu Mang looked confused, why did he start? What did he start?

suddenly

Seeing Xiao Man close her eyes, her small mouth pursed slightly, if it weren't for her expectant look, Xu Mang might have thought that she had been wronged.

Alas...

In the end, it came to this.

For the sake of science, you can only sacrifice yourself!

(*￣3) (ε￣*)

Three seconds later,

Yang Xiaoman scolded angrily: "Hey! You're too much!"

"What's wrong with me?" Xu Mang looked depressed.

"Is there anything like you?" Yang Xiaoman said in a take-off manner: "It must be more than a minute later!"

I...

Oops,

Got on the thief ship.

Xu Mang sighed and asked silently, "Oh... You quickly talk about vanadium dioxide, preferably in the case of transformation. ”

"Vanadium dioxide is a metal oxide material, although it has phase change properties, it must be operated at a temperature of less than 100 degrees, and the phase change condition is 68 degrees to change, which leads to the high working temperature requirements of this material. ”

"But adding germanium to the film of vanadium dioxide, its atomic number is 32, and the atomic weight is 72.64, which can make vanadium dioxide work at a temperature of more than 100 degrees. Yang Xiaoman said.

Germanium?

Xu Mang had memorized the chemical periodic table a long time ago, and knew that this kind of semiconductor material seemed to be a very good semiconductor material in the fourth cycle.

"What does vanadium dioxide have to do with hydrogen?" Xu asked.

"The hydrogen atom plays a role in regulating the phase change in vanadium dioxide. Yang Xiaoman explained: "It can change the fluidity of vanadium dioxide membrane lipids, which varies according to temperature, and is currently obtained by using high energy-consuming temperature and pressure, as well as precious metal catalysts, but the catalytic metals deposited on the surface are still difficult to eliminate." ”

I see!

Xu Mang suddenly thought of something and touched the piece of waste wood in his pocket.

"You help me see this thing. Xu Mang took out this piece of waste wood and asked curiously: "Why is my thing so hard and not corroded by acid?" ”

“...”

"How is that possible?!" Yang Xiaoman asked in surprise, "You... Where did you pick it up?"

"Laboratory. ”

"The leader of their team asked me to clean up this piece of waste, and I forgot to use plastic tweezers, and I took the piece of waste with iron tweezers and threw it directly into the acid solute, and then it became like this. Xu Mang replied honestly: "Now it is not only hardened, but it will not be corroded by acid." ”

"Impossible!"

Yang Xiaoman immediately shook his head and said with a resolute expression: "Unless a layer of hydrogen atoms is attached to the surface of this thing, it is impossible!"

Yeah!

That's the case!

Xu Mang suddenly discovered a new continent.

......
