I really don't want to lie down and win

"I've been arrested." Xu Mang sighed, "Let me develop some phase-change materials. I know phase change with a hammer."

"Vanadium dioxide?" Yang Xiaoman asked.

"Ugh?!"

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

at this time,

A trace of arrogance appeared on Yang Xiaoman's face: "I am a young, invincible and super beautiful female student god recognized on Weibo!"

"Then do you know what exactly is this vanadium dioxide?" Xu Mang asked.

"Want to know?"

"Ok!"

"It depends on your performance." Yang Xiaoman said proudly, "Let's get started."

Xu Mang looked confused, why did it start?What to start?

suddenly,

Seeing Xiaoman's eyes closed and her mouth pursed slightly, if it wasn't for her expectant look, Xu Mang might have thought that she had been wronged.

Ugh...

Finally got to this point.

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

￣3ε￣

After three seconds,

Yang Xiaoman scolded angrily: "Hey! You are too much!"

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

"Is there anyone like you?" Yang Xiaoman took off and said, "It must be more than 1 minute in the future!"

I...

whoops

On board a pirate ship.

Xu Mang sighed, and asked silently, "Oh... tell me about the vanadium dioxide, it's best to change the situation."

"Vadium dioxide is a metal oxide material. Although it has phase change properties, it must be operated at a temperature below 68 degrees, and the phase change condition is [-] degrees, which makes this material very demanding on the working temperature. high."

"However, adding germanium to the thin film of vanadium dioxide, whose atomic number is 32 and atomic weight is 72.64, can make vanadium dioxide work at a temperature exceeding [-] degrees." Yang Xiaoman said.

锗？

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

"What's the relationship between vanadium dioxide and hydrogen?" Xu Mang asked.

"Hydrogen atoms play a role in regulating the phase transition in vanadium dioxide." Yang Xiaoman explained: "It can change the fluidity of the membrane lipid of vanadium dioxide, which changes according to the temperature. Currently, high energy-consuming temperature and pressure are used. , and noble metal catalysts, but the catalytic metals deposited on the surface are still difficult to eliminate.”

That's it!

Xu Mang suddenly thought of something, and touched the piece of scrap material in his pocket.

"Help me take a look at this thing." Xu Mang took out the scrap material and asked curiously, "Why is this thing so hard and it won't be corroded by acid."

"..."

"How is it possible?!" Yang Xiaoman asked in amazement: "You...where did you pick it up?"

"The laboratory."

"The leader of their team asked me to clean up this piece of waste material. I forgot to use plastic tweezers, and took the iron tweezers to hold this piece of waste material, and threw it directly into the acid solution, and then it became like this." Xu Mang, old man He honestly replied: "Now it not only hardens, but also won't be corroded by acid."

"impossible!"

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

exactly!

This is the case!

Xu Mang suddenly discovered a new continent.

......

Chapter 249 Too cheap to imagine (3/3, because it's really scary, add more)

suddenly,

Xu Mang laughed meanly, his expression could be as obscene as possible, this confused Yang Xiaoman, is he crazy?So is it still too late to book a ward in a mental hospital?Need a sedative shot?

"Hey?"

"What are you smirking at?" Yang Xiaoman rolled her eyes, and said helplessly: "The director of the material department asked you to help with research and development, and you ruined all the materials, I said, why are you so skinny? Woolen cloth?"

"What?"

"You're so skinny... you're not...forget it." Xu Mang glanced at Yang Xiaoman, who was sitting on the head of the bed with the word "queen" written on his forehead, and said helplessly, "Xiaoman...you're right Do you understand chemistry?"

"nonsense!"

"I'm not good at computers, I know everything else about geography, and I can be called an all-around invincible beautiful girl." Yang Xiaoman said disdainfully, "I'm the top scorer in the Zhejiang Provincial College Entrance Examination. Do you know if you are the second place in the college entrance examination?"

Nima,

Xiaoman has relatives here, not only has his temper exploded, it seems that his IQ is also gradually declining.

Is it because of a kiss?

Lower your IQ?

Xu Mang looked at Yang Xiaoman's face, indeed... she was a little surprised at this time, especially the flush on her cheeks, which instantly added a point to Xiaoman, who was originally only sixty points. The score is 61 points.

"Look at what?"

"Seeing too much makes you look like a beast." Yang Xiaoman glanced blankly, and asked silently: "Are you going to start being a thief again at night, sneaking into the Materials Department building and breaking the door lock?"
