"Okay." Connie was startled by Lu Zhou's imposing manner. He hurriedly stored the positive electrode sample in a glassware and quickly returned to the battery mold. He then extracted a small amount of electrolyte from the battery mold and stored it in a test tube.
On the other hand, Lu Zhou quickly walked to the corner of the laboratory and took out another artifact — the Fourier transform infrared spectrometer.
The infrared spectrum was produced by the absorption of specific wavelengths of infrared light when compound molecules vibrated. The wavelength of infrared light absorbed by chemical bond vibrations depended on the dynamic constant of the chemical bond and the reduced mass of the atoms connected at both ends. Therefore, each compound had its own unique infrared spectrum. Therefore, the infrared spectrum was also known as the "molecular fingerprint".
According to the absorption peak on the infrared spectrum, Lu Zhou quickly performed a qualitative analysis of the composition of the electrolyte with the help of a computer. He locked onto the mass fraction of all sulfur-containing functional groups and related compounds in the electrolyte.
The final result was quite gratifying.
There were indeed polysulfide compounds in the solution, but the content was quite low. Even for industrial applications, this material had its flaws, but it was still acceptable.
What surprised Lu Zhou wasn't just the results of the electrolyte analysis, but the results of the scanning electron microscope were also gratifying.
At the nanometer scale, the porous structure of sample No. 23 allowed the electrolyte to enter the composite, increasing the ionic conductivity. At the same time, the adsorption ability on the surface could effectively prevent polysulfide compounds from diffusing into the electrolyte, effectively curbing the shuttle effect.
This also confirmed Lu Zhou's statement that hollow carbon spheres were indeed a promising direction.
Of course, this wasn't the most important thing.
The most important thing was that hollow carbon nanospheres with a specific surface area of 3025m2g-1 and a diameter of 69nm met Lu Zhou's previous prediction!
That was to say, hollow carbon nanospheres with a specific surface area in the range of [2326m2g- 1,3762 m2g-1] and a diameter of [60nm-70nm] could effectively inhibit the diffusion of polysulfide compounds in the electrolyte!
"Unbelievable … We did it, we did it!" Connie waved his fist excitedly. If he wasn't worried that his loud voice would disturb the instrument, he would have yelled out loud.
The corner of Lu Zhou's mouth also raised a trace of a smile, and the stone in his heart was finally lifted to the ground.
However, there was still a long way to go before he could completely solve the problem of the shuttle effect.
But there was no doubt that this was a good start.
"Don't be too excited, we haven't completely solved the shuttle effect." Lu Zhou paused for a moment and said, "After 500 revolutions, the loss rate of the positive sulfur material will increase, and the specific capacity decay rate will also begin to increase. This technology still needs to be improved."
Connie couldn't help but say, "Buddy, you're too strict with yourself. If everyone wants the research results to be taken by the industry and turned into products within a certain period of time, then there's no point in continuing our experiments! "
Connie wasn't lying.
In terms of this result, it was absolutely outstanding.
If it were any other professor who had achieved such a result, they would be so excited that they would forget about everything else. They would probably just change the data and brag about the results.
However, Lu Zhou felt that it was better for him to keep a low profile.
After thinking for a bit, he said, "Although this result isn't perfect and still needs to be improved, it shouldn't be a problem to submit to SCI."
Connie asked, "What are you going to name this new material?"
Lu Zhou thought for a bit and said, "Let's call it HCS-1."
HCS was the acronym for hollow carbon spheres. Because it was a prototype product, it was temporarily labeled as 1.
Connie made a helpless expression. "HCS-1? With all due respect, this name isn't creative at all. It doesn't match its amazing effect at all. Can't you think of a better name for your research results? "
What's the point of naming a stupid material?
You're blaming me for the naming problem?
Lu Zhou was speechless. He said, "Do you have any better ideas?"
Connie suddenly became energetic and suggested, "How about LZ-1? It's quite common to use acronyms for names. "
Lu Zhou: "…"
What the hell?
I thought this guy had some good ideas, but it seems like I was overthinking it.
In the end, Lu Zhou rejected Connie's proposal and used his own plan.
If he really named it according to LZ-1 and LZ-2, it would make him feel like he wasn't doing research, he was just spouting nonsense on a forum.
The HCS-1 looked more comfortable.
…
Although the industrial prospects of HCS-1 were quite limited, it was still valuable. If he met an interested company, they might even pay for his research results.
However, this time, he didn't have to wait for a year to write his thesis.
Lu Zhou was too careful when dealing with the PDMS material. He had to wait a year, and he didn't have any experience.
After consulting his manager, White Sheridan, he learned that when evaluating the novelty of a patent application, although it was clearly stipulated that the content of the patent application could not be published before the "patent application date", as long as the "publication time" was after the "patent application date", it was fine.
Specifically, as long as the patent number was obtained, the thesis could be submitted.
Lu Zhou sat in his office at the Institute for Advanced Study and solemnly wrote an authorization letter. He authorized the patent registration and agency to Star Sky Technology in the Cayman Islands.
Lu Zhou signed his name and sealed the envelope.
Coincidentally, Hadi walked in with a towel around his neck.
This guy from Brazil loved to play football, and he was a member of the Princeton Football Club. Even though football wasn't as famous as baseball or football, there were still a lot of people who played it.
Lu Zhou played with them a few times, but he realized that jogging along Lake Carnegie was more suitable for him, so he stopped going.
He was about to sit down and rest for a while when he saw Lu Zhou writing a letter. Hadi curiously came over.
"Professor, what are you writing?"
Lu Zhou didn't answer. Instead, he handed the letter over.
"Perfect timing, go to the mail room for me and send this letter out."
Hadi took the letter from Lu Zhou and said, "Oh, I shouldn't have come here …"
Lu Zhou: "If you didn't come here, I wouldn't have come to you."
Hadi: "…"
After Hadi left the office with the letter, Lu Zhou began to write his thesis.
Star Sky Technology had established a complete patent department, which could help him with patent applications.
He had two theses to write.
One thesis was on the effect of the specific surface area and pore size of hollow carbon spheres on the diffusion rate of polysulfide compounds. The other thesis was on the HCS-1 hollow carbon sphere material.
The former was purely theoretical in nature, and there would be a lot of pictures, analysis, and arguments. The estimated page length was around 30 pages. The latter was applied in nature, so it was relatively short, around 10 to 15 pages.
Speaking of which, where should I submit this thesis?
Lu Zhou put his hands on the keyboard and thought for a few seconds.
Nature or Science?
