Yang Xu's fists were clenched tightly.
With the last sigh, the turbid air in his chest was expelled, and the last line of calculation brewing in the pen also dropped the last character.
"Please help me deal with it."
"... At least, half of it is right."
Focusing all his attention on the current problem, Lu Zhou meticulously retrieved the experimental data stored in the database through the computer, while converting these data into mathematical language, using the theory of computational materials science to combine these fragmented data. The clues weave into a wide open web.
"Let me try again, if it doesn't work..."
If this project is not axed, which one should he consider next time...
Jinling Institute for Advanced Study.
Although he has not been engaged in material science research for some time since the controllable fusion project, these things are not unfamiliar to him.
It was this theory that won him the Hoffman Medal and the Nobel Prize in Chemistry.
No matter how close they are to this result, if there is no way to solve the most critical nitrogen penetration problem, it will still be of no avail...
At this point, he paused for a moment and continued.
This sentence is tantamount to declaring that all the results they have achieved in the past two years have been a failure...
In this way, the difficulty for him to face this problem is actually much lower than that of others.
As for the rest, nothing beats a quantum computer!
"I have some data here."
"A molecular exchange membrane based on new materials..."
Looking at the small empty bottle in his hand, Lu Zhou couldn't help but sigh.
"No need to try, Brother Qian is right."
It's not that he's bragging. If even he can't solve this problem, I'm afraid no one in the world can.
It's as easy as breathing.
"Xiao Ai."
[Xiao Ai is always here, Master.]
After all, the theoretical model of electrochemical interface structure, which is popular in the entire theoretical chemistry and materials science circles, was created by him.
After coughing slightly, Lu Zhou snapped his fingers and continued.
At the same time, the fatigue and dark bags under the eyes accumulated from staying up late also faded away along with the refreshing feeling that rushed to the brain.
A group of people gathered in front of the experimental equipment, all with solemn expressions on their faces.
Just when he was already thinking about the aftermath, a voice floated over from the direction of the door.
After opening the door and walking into the laboratory, Lu Zhou saw everyone in the laboratory looking at him. Lu Zhou dropped a USB flash drive on the table and added in a relaxed tone.
“There is no need to explain and describe the system wave function for each particle’s motion.”
[By introducing the Hartree equation, we can get... ]
The cold liquid slid down his throat, and the cool feeling that traveled to his brain to wash away fatigue made him shiver.
"We may be thinking wrong."
“The technology of the future is really a good thing.”
I just don’t know if I can survive until that day.
Lu Zhou stopped writing in his hand and looked at the dimly lit morning and dusk outside the window. He took a gentle breath of fresh air outside the window.
[{pi2/2m+V（ri）+1/4πε0∑∫drf|Ψj（rj）|2e2/|ri-rj|｝Ψi（ri）=EiΨi（ri）]
Institute of Computational Materials.
"In short, I need you to replace all the silicon in the membrane with carbon of the same family!"
…
Combined with the inspiration brought to him by the Wreck 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.
Shaking the draft paper in his hand, Lu Zhou looked at the lines of calculations on the paper, and a smile of victory gradually appeared on the corner of Lu Zhou's mouth.
The results are out.
The breeze mixed with the fragrance of morning dew blew slowly by. At this moment, he felt that every pore in his body felt more comfortable than ever before.
If that doesn’t work…
“…Perhaps the technical route of porous silicon-based molecular exchange membranes is wrong in itself.”
Fortunately, Yang Xu and the others have accumulated enough data.
Everything went so smoothly.
The correct way to use computational materials science methods to solve problems is to find a feasible entry point through experimental problems, establish a mathematical model for it, and then use the powerful computing power of computers to analyze the problem from nanoscopic, microscopic, mesoscopic and other scales. Study the movement of each molecule and then deduce the macroscopic properties of the research object.
The sky outside the window turned from night to day without knowing when.
Attracted by the USB flash drive, Yang Xu was stunned for a moment and asked.
Just now, they tried to adjust the pore size of the porous silicon-based molecular exchange membrane. However, neither the results of computer simulations nor the results of experimental tests obtained the results that met their expectations.
The so-called calculations of computational materials science do not come out of thin air.
"Just try to find the spatial wave function of the particle density with only 3 variables..."
After stretching comfortably, feeling the fatigue gradually creeping into his brain from staying up late, Lu Zhou reached out and pinched the center of his brow, then extracted a bottle of energy potion from the system space, unscrewed it and drank it in one gulp.
"...I haven't been this happy for a long time!"
It now seems that research on lithium-air batteries may have reached a dead end.
Lu Zhou, who had fully entered the state, had completely blocked out all interference from the outside world.
[…]
"Please do me a favor."
"This is."
Even if ten thousand people are unwilling to give in, he cannot continue to stick to this technical route. Neither his duties as director nor his reason as a scholar allowed him to do this.
There was a dead silence in the laboratory.
Qian Zhongming, who was standing next to Yang Xu and had been stroking his chin and saying nothing, suddenly broke the silence.
"It would be great if I could have a chance to take a look one day..."
After a while, he took a deep breath as if he didn't want to give up.
"Adjusting the pore size may make oxygen molecules more permeable to this material, but there is no way to essentially change the problem of nitrogen molecules also penetrating into the membrane. Maybe..."
"... When all particles in the system can be calculated, the physical properties of the material can be expected!"
Perhaps, he should give everyone in the project team a holiday, and he himself should take some time to go out and relax, so that he can think about how to write the next report.
Those deep pupils seemed to be connected to a universe, and the mind condensed on the tip of his pen was like a sharp blade cutting iron like mud, cutting into pieces the shackles that blocked him from reaching the end...
This part can be solved with paper and pen.
Continuing to cast his gaze on the rows of calculations filled with more than a dozen pieces of paper, as well as the random sketches drawn one after another, Lu Zhou carefully checked them and confirmed that there were no problems before nodding with satisfaction.
Even Lu Zhou couldn't figure out what materials should be used for the molecular exchange membrane of lithium-air batteries just by relying on a piece of paper.
The tip of the pen flying between the index fingers jumped on the paper, and neat lines of numbers and operators were printed on the draft paper like clouds and flowing water, like galloping cavalry, heading towards the mysterious territory that no one knew, conquering the city.
A series of bubbles quickly popped up in the lower right corner of the computer.
The mathematical model part has been completed.
