Chapter 962 Replace All with Carbon!

The calculation of the so-called computational materials science does not come out of thin air.

Even Lu Zhou couldn't figure out what material should be used for the molecular exchange membrane of the lithium-air battery just by relying on a piece of paper.

The correct posture to use computational materials science methods to solve problems should be to find a feasible entry point through experimental problems, and establish a mathematical model for it, and then use the powerful computing power of computers to solve problems from nanoscopic, microscopic, mesoscopic and other multi-scale Study the movement of each molecule, and then deduce the macroscopic performance of the research object.

Fortunately, Yang Xu and the others have accumulated enough data.

Combined with the inspiration brought to him by Wreckage No. 1, it is equivalent to already knowing part of the answer, and then using the experimental data in hand to calculate the remaining 70% of the answer.

In this way, the difficulty for him to face this problem is actually much lower than others.

Concentrating on the current problem, Lu Zhou meticulously retrieved the experimental data stored in the database through the computer, and at the same time converted these data into mathematical language, and used the theory of computational materials to convert these fragmented The clues are woven into a wide open web.

Everything went so smoothly.

It's as easy as breathing.

Although he hasn't been engaged in material science research for some time since the controlled fusion project, these things are not unfamiliar to him.

After all, the theoretical model of electrochemical interface structure, which has swept the entire theoretical chemistry and materials science circles, was created by him.

And it was this theory that earned him the Hoffman Medal and the Nobel Prize in Chemistry.

It's not that he is bragging, if even he can't solve this problem, no one in this world can.

The tip of the pen fluttering between the index fingers was jumping on the paper, neat lines of numbers and operators were printed on the draft paper like flowing clouds and flowing water, like galloping cavalry, heading towards the mysterious area that no one knew, all the way to attack the city and conquer the land.

[By introducing the Hartree equation, we can get...]

[{pi/2m+V(ri)+1/4πε0∑∫drf|Ψj(rj)|e/|ri-rj|}Ψi(ri)=EiΨi(ri)】

【…】

Lu Zhou, who has fully entered the state, has completely shielded all interference from the outside world.

Those deep pupils seem to be connected to a universe, and the mind condensed at the tip of his pen is like a sharp knife that cuts iron like mud, cutting apart the shackles that prevent him from reaching the end...

"There is no need to explain and describe the wave function of the system for each particle motion."

"Just try to find the spatial wave function for particle density with only 3 variables..."

"...when all the particles in the system can be calculated, the physical properties of the material can be predicted!"

"...It's been a long time since I've had such a good time!"

With the last sigh, the turbid air in his chest was spit out, and the last line of calculation that was brewing in the pen also dropped the last character.

The results are out.

The sky outside the window turned from night to day without knowing when.

The pen in his hand stopped, looking at the dawn and dusk outside the window, Lu Zhou gently took a breath of fresh air outside the window.

The breeze mixed with the fragrance of morning dew blows slowly, and at this moment, he only feels that every pore in his body is more comfortable than ever before.

After stretching comfortably, Lu Zhou felt the fatigue gradually creeping up his brain due to staying up late, reached out and pinched the center of his brows, then extracted a bottle of energy medicine from the system space, unscrewed it and drank it in one gulp.

The cold liquid slid down his throat, and the refreshing feeling that rushed to his brain to wash away his fatigue immediately made him shiver uncontrollably.

At the same time, the tiredness and dark bags under the eyes accumulated from staying up all night also faded away along with the refreshing feeling rushing to the brain.

"The technology of the future is really a good thing."

Looking at the small empty bottle in his hand, Lu Zhou couldn't help but sigh with emotion.

"If only I had the chance to take a look one day..."

I just don't know if I can live to that day.

Continuing to look at the calculation formulas filled with dozens of sheets of paper, and the sketches that he drew casually, Lu Zhou checked it carefully, and nodded in satisfaction after confirming that there was no problem.

The part of the mathematical model has been done.

This part can be solved with paper and pencil.

As for the rest, there's nothing like a quantum computer!

"Xiao Ai."

In the lower right corner of the computer, a string of bubbles popped up quickly.

【Xiao Ai is always here, master. (^^*)】

"Please do me a favor."

Shaking the draft paper in his hand, looking at the line of calculations on the paper, Lu Zhou's mouth gradually evoked a triumphant smile.

"I have some data here."

"Please help me deal with it."

...

Jinling Institute for Advanced Study.

Institute for Computational Materials.

A group of people gathered around the experimental equipment, all with serious expressions on their faces.

Just now, they tried to adjust the pore size of the porous silicon-based molecular exchange membrane. However, neither the results of computer simulation nor the results of experimental tests met their expectations.

It now appears that the research on lithium-air batteries may have entered a dead end.

No matter how close they have come to this result, if there is no way to solve this most critical nitrogen permeation problem, it is still useless...

"Our thinking could be wrong."

Standing beside Yang Xu, Qian Zhongming, who had been rubbing his chin and not speaking, suddenly broke the silence.

"Adjusting the pore size may make oxygen molecules more permeable to this material, but there is no way to fundamentally change the problem that nitrogen molecules also permeate into the membrane, perhaps..."

Having said that, he paused for a moment and continued.

"...Maybe the technical route of the porous silicon-based molecular exchange membrane itself is wrong."

There was a deathly silence in the laboratory.

This sentence is tantamount to declaring that all the achievements they have made in the past two years are failures...

Yang Xu clenched his fist tightly.

After a while, he seemed to be unwilling to give up, and took a deep breath.

"Let me try again, if it doesn't work..."

If not...

Even if he is ten thousand unwilling, it is impossible for him to continue to stick to this technical route. Neither his duties as a director nor his reason as a scholar allowed him to do so.

Perhaps, he should give everyone in the project team a vacation, and he himself has to take some time to go out and relax, so that he can think about how to write the next report.

If this project is not cut, which one should he consider next time...

Just when he was already thinking about his funeral, a voice floated from the direction of the door.

"You don't need to try, Brother Qian is right."

Pushing open the door and walking into the laboratory, everyone in the laboratory looked at him in unison. Lu Zhou threw a USB flash drive on the table and added in a relaxed tone.

"...At least, half of it is right."

Attracted by the USB flash drive, Yang Xu was slightly stunned and asked.

"This is."

"A molecular exchange membrane based on a new material..."

Coughing lightly, Lu Zhou snapped his fingers and continued.

"In short, I need you to replace all the silicon in the membrane with the same family of carbon!"

The monthly ticket list suddenly jumped up one place, but why did I feel a little shivering instead of joyful at all. Although we are probably safe, this is too scary... QAQ
