Chapter 907 The Problem that Stumped Two Academicians

[I am the president of a university] []

"Academician Han is looking for me?"

Chen Hao was surprised. The man in front of him was called Luo Hua, a doctoral student at the institute, and his mentor was Han Xiangqian, the director and an academician of the Longguo Academy of Sciences.

Luo Hua nodded and led Chen Hao out directly.

In another laboratory in the institute.

There were several people standing in front of computers, and the atmosphere seemed a bit gloomy, especially the leader's gloomy face, like a volcano that was about to erupt at any time, making people afraid to approach.

"Teacher, Professor Chen is here." Luo Hua reminded carefully.

Academician Han turned around and put on a forced smile, "Professor Chen, I heard that you were unwell today and almost fainted. Good health should not be underestimated. How many scientists have suffered from diseases because they did not pay attention when they were young. , which directly affected his subsequent scientific research career.”

Seeing the tired look on the other person's face and the deep concern in his tone, Chen Hao smiled bitterly and said helplessly: "Director Zhang told you, right? I understand the truth, and I will pay attention to it in the future. Don't worry."

"It's good to know. Staying up late is too harmful to the body, and you can't stay in the office until three or four in the morning again and again. How can this be done? If President Xu of your Long University knew about it, he would not come to my door and criticize me for several days. Academician Han frowned and admonished. Professor Chen in front of him is not only highly valued by Longjing University, but also deeply concerned by the country.

As long as such an extremely talented young scientist grows up, his future will be far superior to him, and it is not impossible for him to even become a leader in Dragon Kingdom's academic circles.

The Dragon Kingdom ranks first in the world in terms of economy and culture, but only in recent years has it lagged behind Kenya on the other side of the ocean in the academic and scientific research fields.

This is a shame for the scientists of the Dragon Kingdom.

Academician Han's words also attracted the attention of the others around him. They were both pleased and dissatisfied, and they all "attacked" Chen Hao.

"Do calculations until three or four in the morning? Not once or twice? Professor Chen, I'm not telling you, you are completely ruining your body, but you must not do this again!"

"Old Huang is right. After this problem, there will be another problem, but the body is only this one. Damage to the liver and kidneys will be difficult to repair. "

"Principal Xu asked me to take more care of you a few days ago, so as not to let you suffer in the institute. You... oh, Professor Chen, please don't stay up late again."

Chen Hao's head was pounding when he heard this, and he quickly said: "Academician Huang, Professor Li, Professor Qian, I promise not to stay up late again in the future."

Ahem, I only said I wouldn’t stay up late, but I didn’t say I wouldn’t stay up all night.

After hearing Chen Hao's assurance, the worries of Academician Han and others immediately dissipated.

But when he thought of the current predicament, Academician Han frowned, and suddenly a bright light flashed in his mind, and he said with a sense of luck:

"Has Professor Chen studied porous silicon materials?"

"Porous silicon material?" Chen Hao pondered for a moment and said modestly: "I touched on it a little bit when I was in Kenya, and I know a little bit about it."

Porous silicon is a new type of one-dimensional nanophotonic crystal material with a "quantum sponge"-like microstructure with nanometer silicon atomic clusters as the skeleton. It can be formed by electrochemical anode corrosion or chemical corrosion of single crystal silicon.

The original person doesn't understand, but he understands.

Coupled with his attraction to the technologies that come with photonic screens, optical cores, and smart thermostats, he has profound insights into the fields of optics, electricity, electrochemistry, and carbon nanotechnology.

"It's a problem with porous silicon-based molecular exchange membranes."

Academician Han stepped aside to make room for the researcher sitting in front of the computer to operate the computer. While the screen appeared, he told Chen Hao:

"Based on experimental analysis, we found that under a certain pressure difference in this type of porous silicon material, the gas on the high-pressure side can slowly transport molecules of a specific diameter to the low-pressure side..."

"The upper and lower boundaries of the filtering interval are not fixed values, but change linearly with the air pressure..."

"We try to increase the surface air pressure on one side of the exchange membrane, and molecules of a specific diameter will pass through the channels in the molecular exchange membrane at a certain rate..."

At the end, Academician Han was a little annoyed and couldn't help but slap the table hard.

"A series of impurities including water molecules, carbon dioxide, and even carbon monoxide are easy to deal with, but we can't do anything about nitrogen!"

"It's been almost 2 months and it still doesn't work!"

In other fields, nitrogen is used as a protective gas, but in lithium-air batteries, the existence of nitrogen has become a burden.

Because lithium metal is too reactive, once nitrogen is allowed to come into contact with lithium, unstable lithium nitride (Li3N) will be generated. Therefore, if you want to conquer lithium-air battery technology, the nitrogen must be eliminated.

However, it is easy to say but very difficult to do.

As the leader of the project, Han Xiangqian is an authority in the field of lithium batteries in Longguo and even the world, but he cannot solve this problem.

Other members of the project team, such as Academician Huang, Professor Li, Professor Qian and others, were also at a loss.

"Let me see." Chen Hao took the position of the researcher in front of the computer, operating the mouse and carefully observing the three-dimensional composition of the silicon-based molecular exchange membrane on the screen.

The more he looked at it, the more solemn his expression became.

From the beginning, he did not take him lightly. After all, the problem that could stump two academicians and many professors from famous universities would definitely not be simple.

But he didn't expect things to be more difficult than he expected.

"It's really troublesome." Chen Hao said in a deep voice without looking away from the screen.

"Alas."x4

After Chen Hao's expression, there was a sigh.

Perhaps they should have known that Chen Hao could not solve this problem, and it was just a fluke.

I thought that if Professor Chen was extremely talented, he might come up with a solution.

"I have an idea, I'll give it a try these days." Chen Hao didn't dare to vouch for this. After all, this is lithium-air battery technology.

"Okay, just give it a try. It's best if you can hold on." Academician Han comforted him.

"..." Chen Hao knew that Academician Han and others did not take his words seriously. They simply thought it was a good thing for the young man.

But in fact, after digesting the memory and combining it with the original world's understanding of lithium-air batteries, he really caught a clue.

"Academician Han, Academician Huang... Then I will go back first, and call me if you need anything." Chen Hao scratched his head and had nothing to say, so he simply said goodbye and left.

On the way back to the office, he muttered quietly, seeming to be calculating something, and even got distracted and almost bumped into someone else.

Especially after sitting in his seat, he couldn't control himself and started calculating on the scratch paper with a black writing pen.

Sometimes he frowned, sometimes he suddenly realized, and his whole person fell into a state of madness.

Even if the sky outside turns from bright to dark, he doesn't care.

Five hours later.

Until a group of uninvited guests arrived...

&: Now you can comment. Are there any left alive?
