When I am reborn, I just want to be a top student

Chapter 285 A technological breakthrough that can be published in a top journal

There is actually not much fancy stuff in materials science research.

With repeated experiments, a little bit of summary, and a little luck, the experiment may be successful, but the most likely possibility is that there will be no gain.

At this moment, following Wang Donglai's actions.

The atmosphere in the entire laboratory became somewhat solemn, and everyone was quietly waiting for the test results to come out.

soon.

On the screen, the microscopic structure of the hollow carbon sphere was scanned and then printed out as an image.

Seeing these pictures, Wang Donglai's eyes lit up, and he said to Lu Tu: "Senior, please help me pick out some hollow nanospheres with a surface area in the range of [2054g-1, 3425g-1] from the samples."

This was not a problem for Lu Tu, so he finished it quickly 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 went to prepare.

Everyone started to help, and everything was ready in just a few minutes.

It can be said that the completeness and advancedness of the laboratory equipment at Galaxy Technology are among the best even in Tangdu, where there are many universities. Except for some truly top-notch large equipment, other instruments are available.

If a worker wants to do his job well, he must first sharpen his tools!
Wang Donglai still understands this truth very well.

So, against all odds, a large amount of funds were allocated from Galaxy Technology's account to purchase instruments and equipment.

The benefits of doing so are naturally reflected at this moment.

When you need to use it, you can use it directly without having to worry about borrowing instruments or renting laboratories.

After the instruments were ready, we started making battery samples.

Manufacturing batteries was naturally an extremely simple and effortless task for everyone present.

"Classify the samples and mix the hollow carbon ball powder and elemental sulfur in a ratio of 30%, 20%, and 10% respectively to make the positive electrode material. After the battery is made, keep good records. There should be no problem, right?"

When talking about serious matters, Wang Donglai was extremely serious.

Lu Tu and others were also influenced by Wang Donglai's attitude, and they all nodded seriously in agreement.

After Wang Donglai gave the order, there was no mention of the negative electrode material of the battery. The reason was very simple.

This is mainly because the negative electrode material is mainly a combination of PD film and copper core lithium sheet. This combination is also the mainstream in the market today and is standard. There is no unnecessary change and no need for change.

Therefore, Wang Donglai did not mention the negative electrode material, and Lu Tu and others also understood this.

Mixing hollow carbon ball powder and elemental sulfur to make positive electrode materials is not a simple task.

The required process was somewhat complicated, but it was not a big deal since the people present were all experienced and skilled researchers with a lot of experience, so it didn’t take too long.

Materials science experiments are just like this, constantly working on it and experimenting.

Many times, it doesn’t feel like an experiment at all. It’s just a matter of luck, or trial and error, using the process of elimination to find the correct answer.

While busy with all these, Wang Donglai thought of artificial intelligence technology.

If artificial intelligence technology really achieves a breakthrough, experiments like this one that involve trial and error and require no technical expertise can be handled by artificial intelligence, fully freeing up human resources.

Although machines are dull, they are much more reliable than humans.

The most important thing is that machines can work 24 hours a day and are far more efficient than humans.

However, the current artificial intelligence technology is completely unable to do this.

Even if he could do it, Wang Donglai would not take it out right away. He would definitely take it out after various verifications and preparations.

The reason is very simple. There is no good or bad technology. If it is used properly, it will be correct. If it is used improperly, it will be crooked.

While thinking about the impact of artificial intelligence technology, Wang Donglai's hands' movements were not affected at all.

Naturally, a breakthrough in lithium-sulfur batteries cannot be achieved 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.

This is when mathematics comes into play. Although it cannot give a direct answer, it can narrow the range of answers and shorten the time.

……

While Wang Donglai was busy with experiments.

"Mathematical Future" is finally published.

Because people knew that the paper published this time would prove the hailstone conjecture, it attracted attention from the academic community as soon as it was published.

Not only mathematicians, but also many scholars and professors in other fields have a curiosity.

To put it strictly, the hail hypothesis is not a very powerful hypothesis.

Because proving the hail conjecture does not have much practical significance.

From the beginning, the hailstone conjecture was a numbers game.

From down-to-earth poker and mahjong, to the so-called IQ-training Sudoku and Rubik's Cube, to various math game puzzles, they are actually all ∏(0, 0) because they are all finitely enumerable.

Of course, everyone has different ideas.

Some people do not think that the proof of the hail conjecture has any useful practical significance, while others feel that it has no impact at the moment, but that does not mean 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" in order to see Wang Donglai's proof paper as soon as possible.

Perhaps the mathematical problem of hailstone conjecture has no practical significance, but the ideas and thoughts to prove this mathematical game problem are definitely meaningful.

Wang Donglai's Chinese and English subjects have reached an extremely high level.

So when writing a paper, it is naturally easy to do.

The content of the paper is detailed and accurate, and the wording is appropriate, giving people a sense of guidance and thought-provoking.

The higher your academic knowledge and the stronger your ability, the more you can feel the excellence and brilliance of the paper.

soon.

Some scholars and professors in the academic community expressed their feelings after watching the film.

"It's really enlightening. I never thought the hail conjecture could be proven this way!"

"It's really eye-opening. Professor Wang Donglai deserves the Fields Award and other awards."

"Professor Wang Donglai has been able to prove difficult mathematical problems one after another. Where is his limit?"

"We will be fortunate enough to see a revolutionary change in the field of mathematics. I have a feeling that modern science and technology will also achieve breakthroughs along with breakthroughs in mathematics!"

“Mathematics is the foundation of all science. When this foundation achieves 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, and naturally there are people who are unhappy about it and sing a different tune.

"The Hailstone Conjecture is nothing more than a math game. It is not very important for the development of mathematics today. Proving this math game problem is nothing!"

"Thinking back carefully, it's not just the hailstone conjecture, even the proofs of the Goldbach conjecture and Zhou's conjecture all reflect this point. These difficult problems have one thing in common, that is, they are famous, but have little practical significance!"

"Those who seek fame and reputation, waste their academic talents, indulge in nationalism, and abandon academic exchanges are undoubtedly courting their own destruction!" There are also many voices criticizing Wang Donglai, and their focus is on the significance of the journal "Mathematical Future" and the mathematical problems proved.

For a while, two factions formed on the Internet and started spitting at each other.

And all this did not affect Wang Donglai at all.

Because he has not left the laboratory in the past two days.

Wang Donglai is very familiar with this kind of all-out work.

Since obtaining the system, he has overworked many times.

Therefore, I have long been accustomed to this kind of liver-burning behavior.

It was the first time that Lu Tu and others saw Wang Donglai do this. In addition to admiration in their hearts, the last trace of resentment was completely eliminated.

Originally, because of their age, they still had a slight sense of pride deep in their hearts. Even though they did not show it when facing Wang Donglai, it was truly hidden deep in their hearts.

But now, that trace of arrogance in their hearts has completely disappeared, and they are full of admiration for Wang Donglai.

During these 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 exceptionally simple in Wang Donglai's hands.

In a very short time, the model was established at a highly efficient speed, and then various conclusions were drawn by solving the model.

In the later stages, everyone even had trouble keeping up with the pace.

I could only subconsciously follow Wang Donglai's instructions and commands.

"Report on the status of various samples!"

Wang Donglai was busy with the work at hand, but he was giving instructions to Lu Tu.

Lu Tu suddenly became alert and began to report the sample situation to Wang Donglai.

"The first set of samples failed, sulfur element was deposited!"

As he spoke, Lu Tu took the scanned images of the first set of samples under the scanning electron microscope and prepared to hand them to Wang Donglai for inspection.

"I won't look at it. Just handle it yourself. Then continue to report on the other samples!"

Wang Dong came over and gave instructions without even looking at the picture handed to him, and gave instructions without even raising his head.

"Ok!"

Lu Tu nodded in agreement and began to report on the situation of other samples.

"The second group failed. The sulfur and hollow carbon condensed into a mass!"

"The third group, large-scale deposition of elemental sulfur!"

"The fourth group is still holding on, but the situation is not good. It feels like they will fail at any time!"

Lu Tu is reporting on the sample situation.

Wang Donglai suddenly raised his head, his eyes bright, and asked Lu Tu: "Focus on observing the fourth group of samples. Is there any change in the volume of the negative electrode material?"

Hearing Wang Donglai's question, Lu Tu didn't think much about it, and subconsciously moved his eyes closer to watch.

Seeing this scene, Wang Donglai did not get angry. He knew that Lu Tu had been working intensively with him in the laboratory for the past few days and was already exhausted. He could tell from the huge dark circles under his eyes.

"Professor, it seems to have grown in size!"

Lu Tu hesitated for a moment and said so.

After saying that, Lu Tu reacted immediately, grabbed the high-precision vernier caliper beside him, and started measuring.

After a moment, 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 let's directly conduct the electrolyte chemical composition analysis test on the fourth group of samples!"

Lu Tu was not stupid either, and now he had realized what was going on. He said excitedly, "Okay!"

Having said that, Lu Tu began to prepare for the chemical composition analysis.

Wang Donglai walked aside, turned on the Fourier transform infrared spectrometer, and used this machine to analyze the composition of the electrolyte.

In the laboratory, the Fourier transform infrared spectrometer has another name, called experimental artifact!

There were only wrong names, not wrong nicknames.

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 property of compound molecules to absorb infrared light of specific wavelengths when they vibrate to generate an infrared spectrum. Each compound has its own unique infrared spectrum, which becomes an alternative fingerprint of the compound.

Therefore, in the laboratory, the Fourier transform infrared spectrometer is extremely easy to use and has a wide range of practical applications.

soon.

Wang Donglai analyzed the chemical composition of the electrolyte using a Fourier transform infrared spectrometer.

The result made Wang Donglai very satisfied.

Sulfur compounds appeared in the electrolyte, although not much, but they did appear.

Wang Donglai knew very well what this meant.

However, Wang Donglai did not get carried away by this. He remained calm, took the electrolyte under the scanning electron microscope and continued to observe it.

Under observation under a scanning electron microscope, Wang Donglai was also very satisfied with the results.

The fourth group of samples showed results and fulfilled his vision.

The porous structure allows the electrolyte to enter the interior of the composite material more easily, making the ionic conductivity stronger. The surface adsorption capacity effectively prevents the diffusion of polysulfide compounds in the electrolyte, effectively curbing the shuttle effect.

It can be said that although the experimental conditions of the fourth group of samples were not very ideal, they also completed Wang Donglai’s theoretical idea.

In other words, the experiment was successful!

Of course, this is just a glimmer of hope, and it is still some distance away from the final product.

Lu Tu and others also noticed these results.

"Professor Wang, did we succeed?"

When this question was asked, everyone except Lu Tu held their breath and dared not breathe.

Glancing at everyone, Wang Donglai smiled, nodded, and said, "Yes, we succeeded!"

Suddenly, everyone's faces were filled with happy and relaxed smiles and their expressions were excited.

Wang Donglai did not disappoint everyone by telling them that this was only the success of the first stage. The next step would be to deal with the attenuation of 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 until everyone calmed down, then he said, "The next thing will be very simple. Continuously optimize the ratio, record it, improve the process flow, and standardize it. It won't be a problem for you."

"I'll leave these tasks to you. Do you have confidence?"

Hearing this, everyone agreed excitedly as if they had been injected with chicken blood.

At this moment, a familiar voice sounded in Wang Donglai's mind.
