Chapter 285: Technological breakthroughs that can be published in top publications
In fact, there are not many bells and whistles in the research of materials science.
Experiment after experiment, summarize a little bit, and add a little luck, the experiment may be successful, but the biggest possibility is that there will be no gain.
At this moment, following Wang Donglai’s actions.
The atmosphere in the entire laboratory became a little solemn, and everyone was quietly waiting for the test results to come out.
soon.
On the screen, the microstructure of the hollow carbon spheres is scanned, and then printed into a picture.
Seeing these pictures, Wang Donglai's eyes flashed with light, and he ordered Lu Tu: "Senior, help me select some samples with surface areas in [2054g-1, 3425g-1] The hollow space of the interval spreads out the nanospheres.”
This is a small thing. , naturally it was not a problem for Lu Tu, so he quickly finished it and asked: "Professor Wang, is there anything else?"
Wang Donglai was not polite, and immediately said again: "Get the battery tester and battery mold ready, I will use them later!"
Lu Tu nodded and immediately got ready.
Everyone also started to take action, and they were ready in just a few minutes.
It can be said that the complete and cutting-edge laboratory equipment of Galaxy Technology is one of the best even in Tangdu, which is full of universities. Except for some truly top-notch large-scale equipment, other instruments are all available. .
If a worker wants to do his job well, he must first sharpen his tools!
Wang Donglai still understands this truth very well.
Therefore, against all objections, a large amount of funds were allocated from Galaxy Technology's account to purchase instruments and equipment.
And the benefits of doing so will naturally be reflected at this moment.
When you need to use it, you can use it directly without having to think about borrowing instruments, renting laboratories, etc.
After the instrument is ready, we start making battery samples.
Making batteries is naturally an extremely simple and effortless matter for everyone present.
"Classify the samples and mix hollow carbon ball powder and elemental sulfur in proportions of 30%, 20%, and 10% respectively to make positive electrode materials. After the battery is made, keep records. There should be no problem, right?"
< br>When talking about business, Wang Donglai was extremely serious.
Lu Tu and others were also affected by Wang Donglai's attitude, and they all nodded in agreement with serious faces.
After Wang Donglai gave the order, he did not mention the negative electrode material of the battery. The reason is very simple.
This is mainly because the negative electrode material is mainly a combination of PD film and copper core lithium flakes. This combination is also the mainstream on the market today, and it is standard. There are no unnecessary changes at all, and no changes are necessary. .
Therefore, Wang Donglai did not mention the negative electrode material, and Lu Tu and others also understood this.
It is not a simple matter to mix hollow carbon ball powder and elemental sulfur to make a cathode material.
The required process is also a bit complicated, but that's okay. The people present are all experienced and skilled researchers with rich experience, and it doesn't take long.
Experiments in materials science are like this, keep doing things and keep experimenting.
Many times, it’s not like an experiment at all, it’s just luck, or trial and error one by one, using elimination to find the correct answer.
While busy with this, Wang Donglai thought of artificial intelligence technology.
If artificial intelligence technology really achieves a breakthrough, such untechnical trial-and-error experiments can be handled by artificial intelligence, fully liberating manpower.
Although machines are dull, their reliability is much better than humans.
The most important thing is that the machine can work 24 hours a day and is far more efficient than humans.
The current artificial intelligence technology is completely unable to do this.
Even if it could be done, Wang Donglai would not take it out immediately. He would only take it out after various verifications and preparations.
The reason is also very simple. Technology is not good or bad. If it is used correctly, it will be righteous, and if it is used incorrectly, it will be crooked.
Thinking about the impact of artificial intelligence technology, Wang Donglai’s movements on his hands had no impact at all.
The breakthrough of lithium-sulfur batteries naturally cannot happen in a day or two.
Even if Wang Donglai takes action, the test results will not come out instantly.
After all, it takes time to record data and then find problems through the data.
Mathematics comes into play at this time. Although it cannot directly give the answer, it can narrow the scope of the answer and shorten the time.
……
While Wang Donglai was busy experimenting.
"The Future of Mathematics" is finally published.
Because I knew that this time there was a paper that proved the hail conjecture, it attracted a lot of attention from the academic community as soon as it was published.
Not only mathematicians, but also many scholars and professors in other fields are curious.
If you describe it rigorously, the hail conjecture is not a powerful conjecture.
Because it proves the hail conjecture, it does not have much practical significance.
From the beginning, Hailstorm has been a numbers game.
From the down-to-earth poker mahjong, to the so-called Sudoku Rubik's Cube for training IQ, to various mathematical game problems, they are all ∏(0,0), because they are all finite and enumerable.
Of course, everyone has different ideas.
Some people do not think that the hailstone conjecture has any useful practical significance, but some people think that it has no impact at the moment, which does not mean that it has no value.
However, the academic community has different opinions on the proof of the hail conjecture, but they all chose to subscribe to "Mathematical Future" and wanted to watch Wang Donglai's proof paper as soon as possible.
Perhaps Hailibing’s conjecture of this mathematical problem has no practical significance, but the ideas and ideas to prove this mathematical game problem are absolutely meaningful.
Wang Donglai’s [Chinese] and [English] subjects have reached an extremely high level.
So when writing a paper, it is natural to be at your fingertips.
The content of the paper is detailed and accurate, and the wording is appropriate, giving people a persuasive and thought-provoking feeling.
The higher the level of academic knowledge and the stronger the ability, the more you can feel the excellence and excitement of the paper.
Soon.
There are scholars and professors in the academic world who expressed their feelings after reading it.
“I was so enlightened that I never imagined that the hail conjecture could be proved in this way!”
“It’s an eye-opener. Professor Wang Donglai has won the Fields and other awards, and he is indeed well-deserved.”
“Continuously proving mathematical problems one after another , where is the limit of Professor Wang Donglai?”
“We will be fortunate to see a tremendous change in the field of mathematics. I have a hunch that modern science and technology will follow the breakthroughs in mathematics. Get a breakthrough!”
"Mathematics is the foundation of all sciences. When this foundation gets a huge breakthrough, modern science will also usher in a great innovation!"
"..."
There is no doubt that, The reason why these scholars and professors said this is because they have understood Wang Donglai's proof paper.
Some people praise Wang Donglai, but naturally some people are not happy about it and sing the opposite tune.
“The Hail Conjecture is nothing more than a mathematical game. It is not of great importance to the development of mathematics today. It proves that this mathematical game problem is nothing!”
"Looking back carefully, not only the hail conjecture, but also the proofs of Goldbach's conjecture and Zhou's conjecture reflect this. These problems all have one thing in common, that is, they are famous, but they have little practical significance! "
"Those who seek fame and reputation waste their academic talents, indulge in nationalism, and abandon academic exchanges, which is undoubtedly their own destruction!" There are many voices criticizing Wang Donglai, and their starting point is from "The Future of Mathematics" 》Journals and proofs to start with in terms of mathematical puzzles.
For a time, two parties formed on the Internet, each of which started spitting at each other.
But all this did not affect Wang Donglai at all.
Because he hasn't left the laboratory in the past two days.
Wang Donglai is very familiar with this kind of all-out violent behavior.
Ever since he obtained the system, he has had many violent outbursts.
So, I have long been accustomed to this kind of liver-exploding behavior.
This was the first time for Lu Tu and others to see Wang Donglai do this. While admiring him, the last trace of dissatisfaction was completely eliminated.
Originally, because of their age, they still had a little bit of pride deep in their hearts. Even if they didn't show it when facing Wang Donglai, it was really hidden in their hearts.
But now, the trace of arrogance in their hearts was completely eliminated, and they completely admired Wang Donglai.
In the past two days, Wang Donglai integrated various data together, and then established a mathematical model based on these data.
In the eyes of Lu Tu and others, the complicated data became extremely simple in Wang Donglai's hands.
Three times, two times and two times, the model was built at a high efficiency, and then various conclusions were drawn through solving the model.
In the later stage, everyone couldn't even keep up with the rhythm.
You can only subconsciously follow Wang Donglai's orders and instructions to do things.
"Report on the status of various samples!"
Wang Donglai was busy with what he was doing, but he ordered Lu Tu.
Lu Tu suddenly became energetic and began to report the status of the samples to Wang Donglai.
"The first set of samples failed, sulfur element was deposited!"
As he said that, Lu Tu took the scanned pictures of the first set of samples under the scanning electron microscope and prepared to hand them to Wang Dong for review.
“I won’t look at it anymore. You can just handle it yourself and continue to report on the other samples!”
Wang Dong came to see the pictures that were handed to him, without even looking up. He ordered.
“Hmm!”
Lu Tu nodded in agreement and began to report on the other samples.
"The second group failed, sulfur element and hollow carbon condensed into blocks!"
"The third group, sulfur element was deposited on a large scale!"
"The fourth group , I am still persisting, but the situation is not good, I feel that it will fail at any time!”
Lu Tu is reporting on the status of the samples.
Wang Donglai suddenly raised his head, with bright eyes, and asked Lu Tu: "Focus on the fourth group of samples. Has the volume of the negative electrode material changed?"
Hearing Wang Donglai's inquiry, Lu Tu didn't say much. Thinking about it, he subconsciously moved his eyes over and started watching.
Seeing this scene, Wang Donglai didn't get angry. He knew that Lu Tu had been in the laboratory with him intensely for the past few days and was already exhausted. He could tell just by looking at the huge dark circles on his face.
"Professor, it seems to have grown in size!"
Lu Tu hesitated and said.
After finishing speaking, Lu Tu immediately reacted, grabbed the high-precision vernier caliper on the side, and began to measure.
After a while, he reported with a slightly excited tone: "Professor, the size has indeed increased!"
By this time, Wang Donglai had calmed down and ordered: "Okay, Now directly take the fourth group of samples Let’s conduct the electrolyte chemical composition analysis test on the product!”
Lü Tu was not a fool, and he also reacted now and said excitedly: “Okay!”
After that, Lu Tu started. Preparation for chemical composition analysis.
Wang Donglai walked aside, turned on the Fourier transform infrared spectrometer, and used this machine to analyze the components of the electrolyte.
In the laboratory, the Fourier transform infrared spectrometer also has a name, called experimental artifact!
Only the wrong name, not the wrong nickname.
There is a reason why the Fourier transform infrared spectrometer can be called an experimental artifact.
Its operating principle is very simple. It uses the characteristics of infrared light of a specific wavelength to be absorbed when the compound molecules vibrate to generate an infrared spectrum. Each compound has its own unique infrared spectrum, which has also become the characteristic of the compound. Alternative fingerprints.
Therefore, in the laboratory, the Fourier transform infrared spectrometer is extremely easy to use and has a wide practical range.
Soon.
Wang Donglai analyzed the chemical composition of the electrolyte using a Fourier transform infrared spectrometer.
Wang Donglai was very satisfied with the result.
In the electrolyte, sulfur compounds appeared. Although not much, they did appear.
Wang Donglai knew what this meant.
However, Wang Donglai did not get carried away because of this. He remained calm, took the electrolyte under the scanning electron microscope, and continued to observe.
Under the observation of scanning electron microscope, Wang Donglai was also very satisfied with the results.
The fourth group of samples showed results and had completed his vision.
The porous structure allows the electrolyte to enter the interior of the composite material more easily, and the ionic conductivity becomes stronger. The surface adsorption capacity effectively prevents polysulfide compounds from diffusing in the electrolyte, effectively Curbs the shuttle effect.
It can be said that although the experimental conditions of the fourth group of samples are not ideal, they have fulfilled Wang Donglai's theoretical assumptions.
In other words, the experiment was a success!
Of course, this is just a sign of hope, and there is still some distance to go before the final product.
Lu Tu and others also noticed these results on the sidelines.
“Professor Wang, have we succeeded?”
When this question was asked, everyone except Lu Tu held their breath and did not dare to breathe.
Looking at the crowd, Wang Donglai showed a smile on his face, nodded, and said, "Yes, we succeeded!"
Suddenly, everyone's faces were filled with joy and ease. smiling and excited.
Wang Donglai did not disappoint everyone and told everyone that this was only the success of the first stage. The next step was to deal with the attenuation of the materials, etc., which was not easy.
However, since the direction is right, no matter how many problems there are, they can be solved.
It only takes time for the technology to make lithium-sulfur batteries using hollow carbon spheres to achieve a breakthrough.
Wang Donglai waited for a while, and when everyone slowly calmed down, he said aloud: "The next thing is very simple. Constantly optimize the ratio, record it, improve the process flow, and standardize it. It’s not a problem for you.”
“I’ll leave these tasks to you. Do you have any confidence?”
When they heard this, everyone felt like they were in a state of shock. Agree excitedly.
At this time, a familiar voice also sounded in Wang Donglai's mind.
