Chapter 962

All

Change to carbon?

Yang Xu was stunned.

Qian Zhongming and Liu Bo are also shocked.

All the researchers in the whole laboratory stared at the boat, apparently not responding to his words.

In this way, the eerie silence lasted for ten seconds, only to be broken by Yang Xu, the first to return to his mind.

"All for Carbon material? "

Smiling and shaking his head, Yang Xu put his hand and said, "it's impossible. We've tried, and even at the beginning, we used carbon based materials with more flexible structure. But later, we found that the chemical properties of carbon were not so stable compared with silicon, so we changed it to silicon-based porous materials."

At this point, he made a mockery of himself.

"After all, what we have to do is lithium air batteries, not lithium air bombs."

However, no one in the lab laughed, including himself.

Everyone is in a low mood.

After all, it means two years of hard work for them.

"That's because you didn't find the right way..." With that, the boat looked around. "Is there a blackboard?"

Yang Xu was shocked: "whiteboard has It's right behind you. What are you going to do? '

Land boat also does not explain, just light smile says.

"Whiteboard is fine, too."

After that, he turned to the white board placed against the wall, picked up the marker hanging nearby and thought for a few seconds. Then he wrote on the white board word by word.

[ethylene propylene copolymer, 3,4-polyisoprene, polysulfone crosslinked block copolymer cbgc and its chemical modifier cbgc-m ]

looking at the names of organic substances appearing on the white board in rows, the researchers standing in the laboratory are all confused and don't quite understand what he wants to do.

A little confused, near Qian Zhongming's side, Liu Bo asked in a low voice.

"Academician Lu What are you writing? "

"It seems to be familiar..." Elder martial brother Qian obviously didn't understand, but he was not confused. He looked at the whiteboard and frowned for a long time, and said to himself, "is it the formula of modified PDMS polymer? But it's different... "

The formula of modified PDMS polymer is not so long, and the modified version is only the combination of two compounds in the form of chemical inlay.

At present, there are more than five organic names written on the whiteboard by Lu Zhou

Yang Xu, who is the nearest to Lu Zhou, also didn't understand. Like the school bullies of the Institute of computational materials, he stared at the long list of organic names on the whiteboard.

He knows every organic thing.

Even in this lab.

But when Lu Zhou wrote it on the whiteboard like this, he was a little confused about what he was going to do.

Seeing the pen in Lu Zhou's hand stop, Yang Xu finally couldn't help asking aloud.

"This is..."

"Mix these organics into a film in a certain proportion," Lu continued with a smile after leaving the marker on the table. "Remember to use the cold rolling method as much as possible."

The Adam's Apple moved up and down, staring at the long list of organic names on the white board. Yang Xu's eyes were filled with unbelievable looks.

He does not doubt academician Lu's scientific research ability.

Just

All of these have subverted his understanding of computational materials and materials.

“…… It's too exaggerated. What can be produced by mixing so many organics together? What's more, how are you going to control the dispersion of each component? How to ensure the stability between different components? "

There are not only physical mixing, but also chemical inlaying. The complexity of the whole system may reach the level of chaotic system!

To put it bluntly

How do you get the mixture?

How to calculate the distribution ratio of each group?

Not only the proportion, but also the mixing order and the mixing posture of different components. The products may be two things with different physical properties.

One after another, he shakes out all his problems. Looking at the leisurely and smiling boat, Yang Xu takes a deep breath.

"I don't believe you, I just Well, I'll have it simulated later. "

"No, I'm ready." Lu Zhou pointed to the U disk on the table and continued, "the model is in it. The software is the internal working software of our Institute of computational materials. You should be able to use it."

He hesitated to look at the U disk on the desk. Although some couldn't believe that the land boat could complete such a huge amount of work in such a short time, he nodded doubtfully.

"I'll try."

After that, Yang Xu went to pick up the USB flash disk, plugged it into the computer, then clicked the folder on the screen with the mouse, and ran the whole model.All the researchers in the lab gathered around and stood in front of the computer screen nervously waiting for the results of the calculation.

There is only one exception, that is, the land boat. He had simulated it many times before he came here, so only his face was full of relaxed expressions.

Seeing Lu Zhou, Yang Xu hesitated for a moment and asked.

"May I ask you something?"

Lu Zhou: "what's the matter?"

Yang Xu: " Did you solve this model yesterday? "

Lu Zhou: "that's right."

Although I stayed up all night.

Staring at Lu Zhou like a ghost, just as Yang Xu wanted to express his opinion on this matter, the whine of the high-speed chassis suddenly slowed down.

The simulation results have come out!

All the people came together.

When they saw the results on the screen, the researchers around the computer were stunned.

According to the simulation results, when the surface pressure applied on one side of the carbon based film reaches the mark point a, the oxygen molecules begin to move from one side to the other.

and when the first mock exam was 24h, the purity of oxygen in the gas exchange chamber was as high as 98%. When the simulation time is advanced to 72 hours, the number only fluctuates within 0.1% range, and there is no significant reduction!

From this point of view, this kind of carbon based hybrid material has completely destroyed the previous porous silicon-based molecular exchange membrane in the superiority of molecular screening.

As for their concerns about the stability of the chemical properties of carbon, they did not appear at all. To put it bluntly, this kind of polymer material, which is similar to the modified PDMS film, has strong corrosion resistance and is not as delicate as they expected

Staring at the results on the screen, Yang Xu's eyes were filled with disbelief and ecstasy.

But soon, the expression on his face seemed to be poured with cold water, and he calmed down quickly.

"You are right."

"This hybrid film really works better than the porous silicon-based material we developed earlier, especially in the screening of oxygen molecules."

"But now the problem is still here. Even so, we can't guarantee that all the gas entering the gas exchange room is oxygen -"

in the end, just half of that was interrupted by the boat.

"Who said we must guarantee that the gas entering the gas exchange room must be 100% pure oxygen?"

Looking at Yang Xu's stunned expression, Lu Zhou smiles and gently shakes the cuvette he took out of his fingers. He says with these nostalgic tones.

"I made this thing when I was in Princeton."

"After all these years, there's a chance it'll come in handy."
