All of them …
Replace them with carbon?
Yang Xu froze.
Qian Zhongming and Liu Bo also froze.
All of the researchers in the laboratory looked at Lu Zhou. They obviously didn't understand what he was talking about.
Just like that, the eerie silence lasted for a full ten seconds before it was broken by Yang Xu, who was the first to return to his senses.
"Replace them with … carbon?"
Yang Xu smiled and shook his head. He waved his hand and said, "That's impossible. We have already tried. In the beginning, we even used carbon-based materials, which are more flexible in structure. However, we later discovered that the chemical properties of carbon are not as stable as silicon, so we changed to silicon-based porous materials."
At this point, he mocked himself.
"After all, we're making lithium-air batteries, not lithium-air bombs."
However, no one in the laboratory laughed, including Lu Zhou himself.
Everyone's mood was very low.
After all, this meant that their two years of hard work had gone down the drain.
"That's because you didn't find the right method …" Lu Zhou looked around and asked, "Is there a blackboard?"
Yang Xu said, "There is a whiteboard … It's behind you, what are you doing?"
Lu Zhou didn't explain. He just smiled and spoke.
"A whiteboard is fine."
After that, he turned around and walked to the whiteboard that was placed against the wall. He picked up the marker hanging on the side and thought for a few seconds. Then, he began to write word by word on the whiteboard.
[Ethylene-propylene copolymer, 3,4-polyisoprene, polysulfone cross-linked block copolymer CBGC and its chemical modification CBGC-M …]
The researchers in the laboratory looked at the organic names on the whiteboard and were confused. They didn't know what Lu Zhou was trying to do.
Liu Bo was a little confused. He walked next to Qian Zhongming and whispered.
"Academician Lu … What is he writing?"
"It looks a bit familiar …" Brother Qian obviously didn't understand, but he wasn't completely confused. He stared at the whiteboard and frowned for a long time, muttering to himself, "Is it the formula of the modified PDMS polymer? But it's not exactly the same … "
The formula for the modified PDMS polymer wasn't this long, and the improved version was only the combination of the two compounds in a chemical mosaic.
From the looks of it, Lu Zhou had already written more than five names on the whiteboard …
Yang Xu, who was the closest to Lu Zhou, also didn't understand. He stared at the long list of organic names on the whiteboard, dumbfounded.
He recognized every single organic substance.
Even in this lab.
However, when Lu Zhou wrote it on the whiteboard, he was a little confused. What was he trying to do?
Yang Xu couldn't help but ask when he saw Lu Zhou stop writing.
"This is …"
"Mix these organic compounds according to a certain ratio to form a film." Lu Zhou threw the marker on the table and said with a smile, "Remember to use the cold pressing method."
Yang Xu's throat moved up and down as he stared at the long list of organic compounds on the whiteboard. His eyes were filled with disbelief.
He wasn't doubting Academician Lu's scientific research ability.
It was just that …
Everything in front of him had completely subverted his understanding of computational materials science and materials science.
"This … This is ridiculous. What can you create by mixing so many organic compounds together? Also, how are you going to control the dispersion of each component? How are you going to ensure that the different components are stable? "
There was both a physical mixture and a chemical mosaic. The complexity of the entire system was probably at the level of a chaotic system!
Put bluntly …
How did you come up with this mixture formula?
How did you calculate the ratio of each group?
It wasn't just the ratio. If the ingredients were mixed in a different order and posture, the resulting products might be two completely different things with completely different physical properties.
Yang Xu asked all of his questions. He looked at Lu Zhou, who had a calm smile on his face, and took a deep breath.
"It's not that I don't trust you, I just … How about this, I'll get someone to simulate it."
"There's no need, I'm ready." Lu Zhou pointed at the USB on the table and said, "The model is in there, and the software is the internal software of our Institute of Computational Materials. You should know how to use it."
Yang Xu looked at the USB on the table. Even though he couldn't believe that Lu Zhou could complete such a huge amount of work in such a short period of time, he still nodded.
"I'll try."
Yang Xu walked up and picked up the USB. He plugged it into the computer, opened the folder, and ran the entire model.
All of the researchers in the laboratory gathered in front of the computer screen, waiting nervously for the calculation results.
There was only one person who was an exception, and that was Lu Zhou. Before he came here, he had already used a quantum computer to simulate the model many times. Therefore, he was the only one who had a relaxed expression on his face.
Yang Xu looked at Lu Zhou and hesitated for a second.
He then asked, "Can I ask you something?"
Lu Zhou: "What?"
Yang Xu: "… Did you solve this model yesterday?"
Lu Zhou: "Sort of."
Even though he didn't sleep all night …
Yang Xu stared at Lu Zhou like he was looking at a ghost. He was about to express his opinion on this matter when the high-speed computer suddenly slowed down.
The simulation results were out!
Everyone gathered around.
When the researchers around the computer saw the results displayed on the screen, they were all stunned.
According to the simulation results, when the surface pressure applied to one side of the carbon-based film reached point A, the oxygen molecules began to move from one side to the other.
After 24 hours of simulation, the oxygen purity in the gas exchange chamber was as high as 98%! And when the simulation time advanced to 72 hours, this number only fluctuated slightly within the range of 0.1%, there was no obvious decrease!
Just from this alone, it could be seen that this carbon-based material completely outperformed the previous "porous silicon-based molecular exchange membrane" in terms of molecular screening.
As for the chemical stability of carbon that they were worried about, it didn't appear at all. Basically, this polymer material, which was similar to the modified PDMS film, had strong corrosion resistance, so it wasn't as fragile as they originally expected …
Yang Xu stared at the results on the screen. His eyes were filled with disbelief and ecstasy.
But soon after, it was like a bucket of cold water was poured on his face, and he quickly calmed down.
"You are correct.
"This hybrid film is indeed more effective than the porous silicon-based material we developed before, especially in the screening of oxygen molecules.
"But the problem is that we can't completely guarantee that the gas entering the gas exchange chamber is all oxygen —"
Halfway through his sentence, he was interrupted by Lu Zhou.
"Who said we have to guarantee that the gas entering the gas exchange chamber has to be 100% pure oxygen?"
Lu Zhou looked at Yang Xu's shocked face and smiled. He gently shook a small test tube that he took out of nowhere and spoke in a nostalgic tone.
"I made this thing when I was in Princeton.
"After so many years, I finally have a chance to put it to good use."
