Seeing the astonished expression on Yang Xu's face, Lu Zhou smiled, gently shook the small test tube he took out from somewhere between his fingers, and said in a nostalgic tone.
"It seems familiar..." Brother Qian obviously didn't understand it either, but he wasn't completely confused. He stared at the whiteboard and frowned in thought for a long time, muttering to himself, "Could it be the formula of modified PDMS polymer? But It’s not the same…”
"Mix these organic substances in a certain proportion to form a film," Lu Zhou threw the marker on the table and continued with a smile, "Remember to use the cold rolling film forming method as much as possible."
Lu Zhou: "That's right."
All the researchers in the entire laboratory looked at Lu Zhou blankly, obviously not reacting to his words.
What he saw in front of him had somewhat subverted his understanding of computational materials science, and even the subject of materials science.
Looking at the names of organic compounds appearing line by line on the whiteboard, the researchers standing in the laboratory were all confused and didn't quite understand what he wanted to do.
Even though I stayed up all night without sleeping.
When this simulation process was carried out for 24 hours, the oxygen purity in the gas exchange room was as high as 98%! When the simulation time advanced to 72 hours, this number only fluctuated slightly within the range of 0.1%, and did not decrease significantly!
According to simulation calculations, when the surface air pressure applied to one side of the carbon-based film reaches mark point A, oxygen molecules begin to move from one side to the other.
Yang Xu: "... Did you solve this model yesterday?"
[Ethylene-propylene copolymer, 3,4-polyisoprene, polysulfone cross-linked block copolymer CBGC and its chemical modification CBGC-M...]
As of now, Lu Zhou has written more than five names of organic compounds on the whiteboard...
Staring at the results on the screen, Yang Xu's eyes were filled with disbelief and ecstasy.
to be honest…
"Let me try."
"That's because you didn't find the right method..." As he said that, Lu Zhou looked around, "Is there a blackboard?"
He did not doubt Academician Lu's scientific research ability.
Yang Xu was stunned.
How is the ratio of each group calculated
Smiling and shaking his head, Yang Xu waved his hands and said, "It's impossible. We have already tried it. At the beginning, we even used carbon-based materials that were more flexible in structure. But later we found that the chemical properties of carbon are compared to Silicon is still not that stable, so we changed to the technical route of silicon-based porous materials."
"This hybrid film does work better than the porous silicon-based material we previously developed, especially in screening oxygen molecules."
"Who says we have to ensure that the gas entering the gas exchange chamber must be 100% pure oxygen?"
"Can I ask you something?"
"It's not that I don't believe you, I just... let's do it. I'll have someone simulate it later."
"No, I'm ready." Lu Zhou pointed to the USB flash drive on the table and continued, "The model is inside, and the software written by it is the internal working software of our Institute of Computational Materials. You should be able to use it. "
Staring at Lu Zhou as if he were a ghost, just when Yang Xu wanted to express his opinion on the matter, the whirring sound of the high-speed chassis suddenly slowed down.
"This is… "
The last words were interrupted by Lu Zhou just midway through his words.
Seeing that the pen in Lu Zhou's hand stopped, Yang Xu finally couldn't help but asked.
"After all, what we are trying to do is a lithium-air battery, not a lithium-air bomb."
There was only one exception, and that was Lu Zhou. He had already simulated it many times with a quantum computer before coming here, so there was only a relaxed expression on his face here.
only…
All the researchers in the laboratory gathered around and stood in front of the computer screen nervously waiting for the calculation results.
Yang Xu shook out all his questions like a barrage. Looking at Lu Zhou with a calm smile on his face, Yang Xu took a deep breath.
"Academician Lu... what is he writing?"
Yang Xu was stunned for a moment: "There is a whiteboard... right behind you. What are you going to do?"
As for the stability issues they worried about about the chemical properties of carbon, they did not arise at all. To put it bluntly, this polymer material, which is similar to a modified PDMS film, has strong corrosion resistance and is not as delicate as they originally expected...
It's even in this lab.
His Adam's apple moved up and down, and Yang Xu's eyes were filled with disbelief as he stared at the long list of organic names on the whiteboard.
Speaking of this, he made a self-deprecating joke.
Lu Zhou: "What's going on?"
"you are right."
But after Lu Zhou wrote this on the whiteboard, he was a little confused as to what he was going to do.
Lu Zhou didn't explain either, he just said with a faint smile.
Qian Zhongming and Liu Bo were also stunned for a moment.
"... This, this is too exaggerated. What can be mixed with so many organic substances? What's more, how are you going to control the dispersion of each component? And how do you ensure that the different components can maintain stability?"
After that, he turned around and walked to the whiteboard placed against the wall. He picked up the marker hanging next to it and thought for a few seconds, and then started writing word by word on the whiteboard.
However, no one in the laboratory laughed, including himself.
The recipe for modified PDMS polymers is not that long, and the improved version is just two compounds combined in a chemical mosaic.
"After all these years, I finally have a chance to put it to use."
"I made this thing when I was at Princeton."
After that, Yang Xu stepped forward and picked up the USB flash drive, plugged it into the computer, then held the mouse and clicked on the folder on the screen to run the entire model.
"But the problem still lies here. Even so, we cannot completely guarantee that all the gas entering the gas exchange chamber is oxygen-"
He hesitantly glanced at the USB flash drive on the table. Although he couldn't believe that Lu Zhou could complete such a huge workload in such a short period of time, he still nodded doubtfully.
But soon, the expression on his face seemed to have been poured with cold water, and he quickly calmed down.
After glancing at Lu Zhou, Yang Xu hesitated for a moment and then asked.
Yang Xu, who was closest to Lu Zhou, also didn't understand. Like the top students at the Institute of Computational Materials, he was just as dumbfounded as he stared at the long list of names of organic compounds on the whiteboard.
From this point of view alone, this carbon-based hybrid material has completely surpassed the previous "porous silicon-based molecular exchange membrane" in terms of its superiority in molecular screening.
The simulation results are out!
After all, for them, this means that two years of hard work have been wasted.
all…
Replace it with carbon
Everyone was in a very low mood.
Everyone came forward.
He obviously recognizes every organic matter.
When they saw the results displayed on the screen, the researchers gathered in front of the computer were all stunned.
How did you come up with the recipe for this mixture
"Replace everything with... carbon materials?"
A little confused, Liu Bo approached Qian Zhongming and asked in a low voice.
"A whiteboard will do, too."
Not just the ratio, but also the mixing order and mixing posture of different ingredients, the resulting product may be two things with completely different physical properties.
In this way, the strange silence lasted for ten seconds before being broken by Yang Xu, who was the first to come back to his senses.
There are both physical mixing and chemical mosaic, and the complexity of the entire system may reach the level of a chaotic system!
