Chapter 319 "Nature" Or "Science"?

"Yes," startled by Lu Zhou's aura, Connie hurriedly put the positive electrode material sample in a glass container for safekeeping, quickly returned to the side of the battery mold, and used a pipette to extract a small amount of electrolyte from it. solution, collected in test tubes 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.

Infrared spectrum is produced due to 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 kinetic constant of the chemical bond and the equivalent mass of the atoms connected at both ends, so each compound has its own unique Infrared spectrum, so infrared spectrum is also called "molecular fingerprint".

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

The end result is quite gratifying.

Polysulfur compounds did exist in the solution, but in relatively low amounts. Even as an industrial application, although this material has defects, it is acceptable.

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

At the nm scale, the porous structure of sample No. 23 can allow the electrolyte to enter the interior of the composite, increasing the ionic conductivity. At the same time, the adsorption capacity of its surface can effectively prevent the diffusion of polysulfide compounds into the electrolyte, thereby effectively curbing the shuttle effect.

And this also confirms Lu Zhou's statement that hollow carbon spheres are indeed a promising direction.

Of course, this is not the most critical.

The most important thing is that the specific surface area is as high as 3025m2g-1, and the hollow carbon nanosphere with a diameter of 69nm just meets 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 inhibit the diffusion of polysulfide compounds in the electrolyte!

"It's unbelievable...we made it, we made it!" Connie waved his fist excitedly, and if he wasn't worried that talking loudly would interfere with the instrument, he couldn't help shouting out loud.

The corner of Lu Zhou's mouth also raised a smile, 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." After a pause, Lu Zhou continued, "After a maximum of 500 revolutions, the loss rate of the positive electrode sulfur material will increase, and at the same time the rate of specific capacity decay will also start. Zoom in, the technology has room to improve.”

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

Connie was not lying.

As far as this achievement is concerned, it is absolutely outstanding.

If another professor has made such a result, let alone get carried away with excitement, he might just change the data directly and go out with the result to brag.

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

After thinking for a while, he said, "Although this result is not perfect and needs to be improved, it should be no problem to post an SCI."

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

Lu Zhou thought for a while and said, "Just call it HCS-1."

HCS is the English acronym for Hollow Carbon Sphere, and because it is a trial product, it is temporarily marked as 1.

Connie made a helpless expression: "HCS-1? With all due respect, this name has no creativity at all, and it is not worthy of its amazing effect. Don't you give your own research results a good name? name?"

What a good name for a broken material.

Is it my fault for naming difficulties?

Lu Zhou was speechless: "Do you have any better ideas?"

Connie immediately came to his senses and suggested, "How about LZ-1? It's also quite common to name it with initials."

Lu Zhou: "..."

What the hell?

At first, I thought this guy had some great ideas, but now it seems that he is simply thinking too much.

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

If he really followed the rules of LZ-1 and LZ-2 and named them down, it would always make him feel like he was not doing academics, but pouring water into the forum.

Or HCS-1 looks more comfortable.

...

Although the industrial prospects of HCS-1 are quite limited, no matter how small a mosquito is, it is still meat. If you encounter an interested company, you may pay for his research results.

But this time to write a thesis, there is no need to wait as long as a year.

Lu Zhou was too careful when dealing with PDMS materials. He waited for a year and had no experience.

After consulting his manager, White Sheridan, he learned that when evaluating the novelty of a patent application, although it is clearly stipulated that the content of the patent application cannot be published before the "patent application date", as long as the "disclosure time" After the "patent filing date" it is ok.

Specifically, as long as you get the patent number, you can submit papers normally.

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

After signing his name, Lu Zhou sealed the addressed envelope.

Just at this moment, Hardy with a towel around his neck came in from the outside.

This guy from Brazil loves playing football and is a member of the Princeton Football Club. Although the sport of football is not as famous here as baseball and football, there are still many people who play it.

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

Just as he was about to sit down and rest for a while, when he saw Lu Zhou writing a letter, Hardy came over curiously.

"Professor, what are you writing?"

Lu Zhou didn't answer and passed the letter over.

"It's just in time, go to the mailroom for me and send this letter."

After receiving the letter from Lu Zhou, Hardy said weakly, "Oh, I shouldn't have come here..."

Lu Zhou: "If you don't come here and talk nonsense, I may not necessarily come to you."

Hardy: "..."

Seeing Hardy leaving the office with the envelope, Lu Zhou started writing the thesis.

Xingkong Technology has established a complete patent department, which can solve the problem of patent application for him.

There are two papers to be written.

One paper is about the influence of specific surface area and pore size of hollow carbon spheres on the diffusion rate of polysulfide compounds, and the other is about the research of 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, the estimated number of pages is about 30 pages. The latter is of an application nature, and the length is relatively small, and it can be done in about ten to fifteen pages.

Speaking of which, what is the best choice for this paper?

Lu Zhou put his hands on the keyboard and thought about it for a few seconds.

Nature or Science?

This question is really unfriendly for patients with difficult choices...
