The so-called calculation of computational materials science does not come from nothing.

Even on a land boat, it is impossible to work out what materials should be used for the molecular exchange membrane of lithium air batteries with just one pen and one paper.

The correct posture of using computational materials to solve the problem should be to find a feasible entry point through the experimental problem, and to establish a mathematical model for it. Then, with the help of the powerful computing power of the computer, we can study the movement of each molecule from nano, micro, meso and other multi-scale, and then calculate the macro performance of the research object.

Fortunately, Yang Xu has accumulated enough data.

Combined with the inspiration from wreck one, it is equivalent to knowing part of the answers, and then using the experimental data in hand to calculate the remaining 70% of the answers.

In this way, the difficulty of facing this problem is actually much lower than that of other people.

Focusing on the current problems, Lu Zhou meticulously searches the experimental data stored in the database through the computer, transforms the data into a mathematical language, and weaves these fragmented clues into an open network with the theory of computational materials.

Everything went so well.

It's as easy as breathing.

Although he hasn't been engaged in the study of materials for some time since the controllable fusion project, these things are not new to him.

After all, the theoretical model of electrochemical interface structure, which is popular in the whole theoretical chemistry field and material science field, is made by him.

It was this theory that earned him the Hoffman medal and the Nobel Prize in chemistry.

If he can't solve the problem, no one in the world will be able to solve it.

The tip of the pen flying between the index fingers is jumping on the paper. Lines of neat numbers and operators are printed on the rough paper like flowing clouds and flowing water. Like the galloping cavalry, they are attacking the city in the unknown mysterious area.

[by introducing Hartree equation, we can get ]

【{pi2/2m+V(ri)+1/4πε0∑∫drf|Ψj(rj)|2e2/|ri-rj|}Ψi(ri)=EiΨi(ri)]

【…… ]

the ship that has completely entered the state has completely shielded all external interference.

The deep pupil seems to connect with a universe, and the mind condensed in his pen point is like a blade cutting iron like mud, cutting the shackles that block him to the end point into four parts

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

"Just try to find out the space wave function of particle density with only three variables..."

“…… When all particles in the system can be calculated, the physical properties of the material can be expected! "

“…… It's been a long time! "

With the last sigh, the turbid Qi in the chest will be vomited together, and the last line of calculation in the pen will also fall the last character.

The results have come out.

Out of the window of the sky, I don't know when to start, from night to day.

The pen in his hand stopped and looked out of the window at the dusk. The boat took a breath of fresh air out of the window.

Mingled with the fragrance of morning dew, the breeze blows slowly. At this moment, he only feels every pore on his whole body, which is unprecedented comfortable.

After a comfortable stretch, feeling tired of staying up late and climbing up to the brain, Lu Zhou reached out and pinched his eyebrow, then took a bottle of energy medicine from the system space, unscrewed it and drank it.

The cold liquid glided through the throat, which rushed to the brain to wash away the cool feeling of fatigue, which immediately made him unable to help but hit a spirit.

At the same time, the tired and dark bags of eyes, which were accumulated because of staying up late, also disappeared along with the cool feeling of the brain.

"The technology of the future is really good."

Looking at the empty bottle in his hand, the boat sighed.

"If only I could have a chance to have a look one day..."

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

He continued to look at the lines filled with ten pieces of paper, as well as a sketch that he drew at will. After checking it carefully and confirming that there was no problem, he nodded with satisfaction.

Part of the mathematical model has been worked out.

This part can be solved with paper and pen.

As for the rest, nothing is more suitable than a quantum computer!

"AI."

In the lower right corner of the computer, a series of bubbles pop up quickly.

[AI has been here, master. "(^? ^ *)]

" do me a favor. "

Shaking the draft paper in his hand, looking at the line of calculation on the paper, the corner of Lu Zhou's mouth gradually raised a smile of victory."I have some data here."

"Please help me deal with it."

……

Jinling Institute of higher learning.

Institute of computational materials.

A group of people gathered around the experimental equipment, their faces with solemn expressions.

Just now, they have 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 have met their expectations.

Now it seems that the research of lithium-air battery may be in a dead end.

No matter how close they were to this result, if there is no way to solve the most critical problem of nitrogen permeation, it will not help

"Our thinking may be wrong."

Standing next to Yang Xu, Qian Zhongming, who had been feeling his chin and never spoke, suddenly broke the silence.

"Adjusting the pore size may make the oxygen molecules more permeable to this material, but it can't fundamentally change the problem that nitrogen molecules also penetrate into the membrane, maybe..."

At this point, he paused for a moment and continued.

“…… Perhaps the technical route of the porous silicon based molecular exchange membrane itself is wrong. "

There was a dead silence in the lab.

This sentence is equivalent to declaring that all the achievements they have achieved in the past two years are failures

Yang Xu's fist was clenched to death.

After a while, he took a deep breath as if he were immortal.

"Let me try again, if not..."

If not

Even if ten thousand people don't want to, he can't continue to die on this technical route. Neither his duty as a director nor his reason as a scholar allowed him to do so.

Maybe he should take a vacation for everyone in the project team, and he should take time out to relax himself, so as to think about how to write the next report.

If the project is not cut off, which one should he consider next time

Just when he began to think about the future, a voice came from the direction of the door.

"Don't try, brother Qian is right."

Push open the door and walk into the lab. everyone in the lab looks at themselves. Lu Zhou leaves a U-disk on the table and adds in a relaxed tone.

“…… At least, half right. "

Being attracted by that USB flash drive, Yang Xu asked slightly stupefied.

"This is."

"A molecular exchange membrane based on new materials..."

With a slight cough, Lu Zhou made a loud finger and continued.

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