Scholar’s Advanced Technological System

"Yes," startled by the momentum of Lu Zhou, Connie hurriedly placed the positive electrode material samples in glassware and quickly returned to the side of the battery mold, using a pipette to draw a small amount of electrolysis from the inside The solution was collected in a test tube and sealed. ♀>

On the other side, Lu Zhou quickly walked to the corner of the laboratory and took out another artifact in the laboratory—Fourier transform infrared spectrometer.

The infrared spectrum is generated by the absorption of infrared light of a specific wavelength when a compound molecule vibrates, and the wavelength of infrared light absorbed by chemical bond vibration depends on the chemical bond dynamic constant and the reduced mass of the atoms connected at both ends, so each compound has its own unique The infrared spectrum is also called "molecular fingerprint".

Based on the absorption peaks in the infrared spectrum, Lu Zhou used a computer to quickly make a qualitative analysis of the composition of the electrolyte, and locked the mass fraction of all sulfur-containing functional groups and related compounds in the electrolyte.

The end result is quite pleasing.

Polysulfide compounds do exist in the solution, but the content is quite low. Even if it is used for industrial applications, this material is acceptable, although it has defects.

What surprised Lu Zhou was not just the analysis results of the electrolyte, but the observation results under the scanning electron microscope were also pleasing.

In the nanometer scale, the porous structure of sample No. 23 can allow the electrolyte to enter the interior of the composite and increase the ion conductivity. At the same time, its surface adsorption capacity can effectively prevent polysulfide compounds from diffusing into the electrolyte, thereby effectively curbing the shuttle effect.

This also confirms Lu Zhou's claim that hollow carbon spheres are indeed a promising direction.

Of course, this is not the most critical.

The most important thing is that the hollow carbon nanospheres with a specific surface area of ​​up to 3025m2g-1 and a diameter of 69nm just meet Lu Zhou's previous prediction!

That is, hollow carbon nanospheres with a specific surface area in the range of [2326m2g-1, 3762m2g-1] and a diameter in the range of [60nm-70nm] can effectively suppress the diffusion of polysulfide compounds in the electrolyte!

"It's unbelievable ... we succeeded, we succeeded!" Connie waved his fist in excitement, and could not help shouting loudly if he wasn't worried that loud speech would disturb the instrument.

There was a smile in Lu Zhou's mouth, and the hanging stone in his heart fell to the ground.

Although there is still a long way to go to completely solve the shuttle effect.

But there is no doubt that this is a good start.

"Don't get too excited, we haven't completely solved the shuttle effect," Lu Zhou continued, "after a maximum of 500 revolutions, the loss rate of the positive sulfur material will increase, and at the same time the specific capacity decay rate will start Zoom in, this technology needs to be improved. "

Connie couldn't help but said, "Man, you are too strict with yourself. If everyone requires that the research results be used by industry to make products, our experiments will not need to be continued!"

Connie did not lie to him.

In terms of this result, it is absolutely outstanding.

Another professor has made such a result, not to mention the excitement and forget it, just afraid to change the data directly, and take the results out to brag.

However, Lu Zhou felt that it was better to keep a low profile.

After thinking about it, he said: "Although this result is not perfect and needs improvement, there should be no problem in publishing sci."

Connie asked, "What are you going to name this new material?"

Lu Zhou thought about it and said, "Just call hcs-1."

hcs is the acronym for hollow carbon sphere, because it is a trial work, it is temporarily labeled as 1.

Connie made a helpless expression: "hcs-1? IMHO, this name is not creative at all, and it is not worthy of its amazing effect. Don't you give your research results a good point Is it your name? "

What is the name of a broken material?

Blame me for my name?

Lu Zhou said silently, "Do you have any better ideas?"

Conney immediately came to the spirit and suggested, "What about lz-1? It's common to use acronym names."

Lu Zhou: "..."

What the hell?

Originally, he thought that this guy had any opinions, but now it seems that he is thinking too much.

In the end, Lu Zhou indiscriminately rejected Connie's proposal and adopted his own scheme.

If it really goes down according to the rules of lz-1 and lz-2, it will always make him feel like he is not doing science, but filling the forum.

Still hcs-1 looks more comfortable.

...

Although the industrial prospect of hcs-1 is quite limited, no matter how small the mosquito is, it is meat. If you come across an interested company, you may pay for his research results.

But this time, I don't have to wait for a year to write a thesis.

Lu Zhou was too careful when dealing with pdms materials, waiting for a year, plus no experience.

After consulting with his manager, White Sheldan, he learned that when evaluating the novelty of a patent application, although it is clearly stipulated that the content of a patent application cannot be disclosed before the "patent application date", as long as the "publication time" After the "patent application date", that's it.

Specifically, as long as the patent number is obtained, the paper can be submitted normally.

Sitting in the office of the Institute of Advanced Studies, Lu Zhou solemnly wrote an authorization letter, authorizing the patent registration and agency to Star Technology registered in the Cayman Islands.

The signature section signed his name, and Lu Zhou sealed the filled envelope ~ www.readwn.com ~ just right, at this moment, Hardy with a towel around his neck came in from the outside.

This guy from Brazil loves to play football and is a member of Princeton Football Club. Although football is not as famous here as baseball and rugby, many people play it.

Lu Zhou also kicked them a few times, but later found that jogging along the Carnegie Lake was more suitable for him, so he stopped going.

Preparing to sit down and rest for a while, seeing Lu Zhou writing a letter, Hardy came together curiously.

"Professor, what are you writing?"

Lu Zhou did not answer, and passed the letter.

"Just right here, go to the reception room for me and send this letter."

Receiving the letter from Lu Zhou, Hardy said weakly, "Oh, I shouldn't be here ..."

Lu Zhou: "If you don't stop talking nonsense, I won't necessarily look for you."

Hardy: "..."

Watching Hardy holding the envelope leave the office, Lu Zhou began writing the dissertation.

Xingkong Technology has established a comprehensive patent department that can solve patent application problems for him.

There are two papers to be written.

One paper is about the influence of the specific surface area and pore size of hollow carbon spheres on the diffusion rate of polysulfide compounds, and the other is about the hcs-1 hollow carbon sphere materials.

The former is equivalent to a purely theoretical nature, and many pictures will be inserted, coupled with analysis and demonstration, it is expected that the number of pages will be about 30 pages. The latter is of an application nature and has a relatively small space, which can be done in about ten to fifteen pages.

Speaking of which, what good is this paper?

Lu Zhou, who put his hands on the keyboard, thought for a few seconds.

"Nature" or "Science"?

This problem is really unfriendly to patients with selection difficulties ...
