Half an hour later,

"Ah~"

Yang Xiaoman opened her mouth happily: "I want to take another sip."

"oh."

"By the way, this is the last bite." Xu Mang poured the donkey-hide gelatin, red date and sugar water in the thermos cup onto the spoon, and then carefully handed it to Xiao Man's mouth.

actually

Yang Xiaoman didn't like the donkey-hide gelatin and red date syrup at all. What she liked was the feeling of Xu Mang taking care of herself.

How nice it would be if relatives came to visit every day,

In this way, I can enjoy the care of this idiot every day, and it is still the kind of meticulous care.

no!

You will bleed to death if you do so.

"well?"

"Can you stay in my dormitory one day a week from now on?" Yang Xiaoman asked shyly, "Is that okay?"

"Okay, okay!"

"How are you feeling now?" Xu Mang put the thermos cup back into his bag and asked curiously: "By the way, have you made the headlines on Weibo recently?"

"ah?"

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

The reason why Xiaoman wanted to hide it was because he was afraid that Xu Mang would have random thoughts.

"I'm surprised at you." Xu Mang swallowed back the flat words behind him and smiled helplessly: "Isn't that right?"

"It's you!"

"I am so charming, okay? You are the only one in the world who is blind!" Yang Xiaoman, who had a deep sense of guilt, disappeared in an instant, and said resentfully: "Let me tell you, I am now

My suitors are a group of impositions, so you have to be tight-lipped with me, otherwise you will become single in a minute."

hehe,

cut!

Is the prosperity and beauty a joke?

Xu Mang didn't care at all. He silently found a chair and placed it next to Xiaoman's bed. Then he took out a chemistry book and read the contents carefully.

During the summer vacation,

Xu Mang had already triggered the chemistry skill. The chemistry skill value at this time was not very high, barely enough for 10,000.

How to say,

Junior high school graduation chemistry level.

"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 a little too much. He came here to accompany Xiaoman, but in the blink of an eye he went to study.

Yang Xiaoman:(#￣～￣#)

Very angry!

Really angry!

How could you not love studying when we were not together before? Now that the two of you are together, you suddenly fall in love with studying?

On purpose?

What about beauty being the bane that was promised? Why did I become the catalyst for his diligence and studiousness?

"What did you say during the day?"

"Were you kidnapped by someone from the material department?" Yang Xiaoman asked curiously: "What happened?"

"Don't mention it!"

"I've been caught." Xu Mang sighed: "Ask me to develop some phase change materials. I know hammer phase change."

"Vanadium dioxide?" Yang Xiaoman asked.

"well?!"

"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 academic god recognized on Weibo!"

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

"Want to know?"

"Um!"

"Let's see how you perform." Yang Xiaoman said proudly: "Let's get started."

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

Sudden,

Seeing Xiao Man closing her eyes and pouting her little mouth slightly, Xu Mang might have thought that she had been wronged in some way if it weren't for the expectant look on her face.

well

Finally got to this point.

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

(*￣3)(e￣*)

Three seconds later,

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

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

"Is there anyone like you?" Yang Xiaoman said quickly: "It must be more than one minute from now on!"

I

Oops,

Got on the pirate ship.

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

"Vanadium dioxide is a metal oxide material. Although it has phase change properties, it must be operated at a temperature below 100 degrees, and the phase change condition is 68 degrees before it can transform. This makes this material very sensitive to the working temperature.

It’s very demanding.”

"But adding germanium to the vanadium dioxide film, whose atomic number is 32 and atomic weight is 72.64, allows the vanadium dioxide to work at temperatures exceeding one hundred degrees," Yang Xiaoman said.

germanium?

Xu Mang had long memorized the periodic table of chemistry and knew that this material, in the fourth period, seemed to be a very good semiconductor material.

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

"Hydrogen atoms play a role in regulating phase changes in vanadium dioxide." Yang Xiaoman explained: "It can change the fluidity of the membrane lipids of vanadium dioxide and change it according to the temperature. Currently, high energy-consuming temperature and pressure are used.

, and precious metal catalysts to obtain it, but the catalytic metal deposited on the surface is still difficult to eliminate.”

I see!

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

"Please help me take a look at this thing." Xu Mang took out this piece of waste material and asked curiously: "Why is this thing of mine so hard and not corroded by acid?"

""

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

"Laboratory."

"The leader of their group asked me to clean up this piece of waste material. I forgot to use plastic tweezers, so I held the piece of waste material with iron tweezers and threw it directly into the acid solute, and then it became like this." Elder Xu Mang

He answered honestly: "Not only has it hardened now, but it will not be corroded by acid."

"impossible!"

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

Yes, yes!

This is the case!
