Chapter 183 How Can Scientists' Affairs Be Called Pretense?

Not only have I heard of it, but I have heard of it for a long time.

It is no exaggeration to say that in today's domestic mathematics circles, Mr. Qiu is the well-deserved number one in domestic mathematics.

The only ones who can stand shoulder to shoulder with him are the late Hua Luogeng and Chen Shengshen.

Graduated with a Ph.D. at the age of 22, served as an associate professor at the age of 25, overcame the world's mathematical problem "Carabi's conjecture" at the age of 27, and won one of the crowns in mathematics - the Fields Medal at the age of 34. Just like that Tao Xuanzhe, he was as strong as a hook.

Not only has he won various awards, but his academic achievements have also made him one of the most influential mathematicians in the world today. Its influence spreads over many mathematical fields such as differential geometry, topology, algebraic geometry, representation theory, general relativity, and even high-energy physics!

The most famous of these is his proof of Calabi's conjecture, which directly laid the theoretical foundation for the establishment of superstring theory in the 1980s.

Although there is some unintentional feeling in it, in the field of theoretical physics, this old gentleman is generally regarded as one of the founders of superstring theory.

It can be said that no one who is engaged in mathematics research in China does not know this great god. It is even more impossible for those who study theoretical physics not to know this great god.

But because Mr. Qiu is usually very busy, it's really not easy to meet this boss.

Otherwise, even a few words can benefit a lot.

So, when he heard that Academician Lu was going to take him to visit Mr. Qiu, Lu Zhou immediately asked excitedly, "When are we going to Beijing?"

Academician Lu laughed and said, "October, it's still early."

"..."

What did you tell me so early?

Lu Zhou was speechless for a while.

Seeing that Lu Zhou didn't speak, Academician Lu continued.

"I don't have any projects here for the past two months, so you can settle down and recharge yourself. I have nothing to say about mathematics, but you still have a lot to learn about quantum chromodynamics. The next semester's schedule I have already sent it to your email. If you want to graduate next year, you should work hard on these courses. Whether you attend or not, I will test you at the end of this semester. That’s about it. The scope of the test is first I'll draw it for you, it's the class schedule in your mailbox."

Hearing the capricious test range, Lu Zhou almost vomited blood, coughed dryly and said, "Professor, your test range is too big."

Academician Lu said with a smile: "What are you afraid of? Have confidence in yourself, I am optimistic about you!"

...

No matter how much improvement is needed in quantum chromodynamics, there is one thing that must be resolved as soon as possible.

After coming out of Academician Lu's office, Lu Zhou didn't wander around the empty campus, but returned to the dormitory without stopping, sat in front of the laptop, and began to study the data obtained by the scanner.

Although I don't know what level of civilization this battery is produced, but as far as this battery is concerned, both the industrial level and the technological level far exceed any country on the earth.

Even leaving aside the negative electrode material, the "Oxygen Element Oriented Screening Diaphragm" remaining on the side of the tube wall cannot be produced by existing technical means.

Yes, even if he knows the structure of the material and puts all the parameters in front of him, Lu Zhou can assert without a doubt that even if he puts this thing on the Internet, there is no laboratory that can The separator is produced as thin as a nanoscale thickness.

Without this diaphragm, even if the problem of lithium dendrites is solved, it is impossible to create a lithium-air battery.

As for the reason, anyone who has studied high school chemistry knows that lithium not only reacts with oxygen, but also reacts with nitrogen in the air to form lithium nitride crystals that are difficult to be reduced. If a little water vapor leaks in, the explosion will be comparable to Sodium enters the water much more tragically.

The Japanese have gone a long way in this regard and have great ambitions, but so far there is no good way.

If the problem of gas molecular screening cannot be solved, the lithium-air battery produced must carry an oxygen tank on the back. Mobile phones are unnecessary, and new energy vehicles may still be possible.

However, I believe that no one wants their own car to risk turning into a rocket and flying into the sky every time it is ignited.

After in-depth research, Lu Zhou can now conclude that this battery wreck should be the legendary lithium-air battery.

The positive electrode is a gas chamber covered by a gas screening membrane, and the negative electrode is a lithium negative electrode material wrapped in electrolyte...but now there is no electrolyte leakage left, and the negative electrode material has completely turned into lithium oxide.

The design structure is simple and clear, to the point that no one can copy it even if it is put in front of the people on earth. Because the technical difficulties are all in the details, many problems that originally needed to be solved from the perspective of design have all been solved in the materials.

Even if it is the plastic used inside the battery, Lu Zhou tried to check the molecular formulas on the Internet, but he couldn't find this kind of plastic at all.

Fortunately, the materials needed to protect the lithium anode and prevent the growth of lithium dendrites are nothing special. At least in Lu Zhou's view, it is not impossible to solve.

Deep under the fully oxidized lithium negative electrode material, Lu Zhou observed a piece of copper foil.

Of course, the copper foil as the substrate is definitely not the key to preventing lithium dendrites. The key point is an improved PDMS nanoporous film covered on the copper foil.

The PDMS material is nothing special, it is polydimethylsiloxane, which can even be found in some skin care products and shampoos. The nanoporous structure in this PDMS film is probably one of the keys to solving lithium ion transmission and "breathing problems".

As for the nanoporous film made of PDMS, Lu Zhou speculates based on his limited knowledge of materials science that it can probably be prepared by spin coating and hydrofluoric acid etching. Not to mention completely restoring the technology on that wreck, limited restoration is still possible.

Under the PDMS film, Lu Zhou also observed a layer of specially treated hollow carbon nanospheres.

Through the principle of phenomenon inversion, Lu Zhou guessed that these carbon nanospheres probably "flattened" the lithium dendrites that were still in the moss-like growth stage when lithium ions were discharged on the negative electrode to precipitate lithium elements.

After staring at the screen for about half an hour, Lu Zhou touched the hot motherboard, leaned back on the chair, took a deep breath, and said with emotion.

"The task is difficult!"

The 20,000 yuan computer is running so hard, and it really depends on a professional computer to process the data.

After the patent issue is resolved, he plans to build a laboratory near Jinling University to study this stuff. Then hire a large group of graduate students and doctoral students to work for themselves. At that time, I only need to assign the subject, and even the work of assigning the subject can be handed over to Xiao Ai to do it for me.

However, it is not too late to wait for things to look forward to in the future. No matter whether he becomes "Ding Dong Cat" or "Iron Man" in the future, there are more important things waiting for him to do now.

Taking out a piece of A4 paper from the drawer, Lu Zhou picked up a pen and wrote two words on it, and drew two circles - "PDMS film" and "carbon nanospheres".

He plans to register patents for these two things separately, and then register them as a whole for a patent named "L1 negative electrode material".

In fact, if he has time, he can even figure out the production process, register a set of patents for the supporting industrial production process, and eat up all the profits from this piece. Even if you don't produce it yourself, there is no problem at all if you package and sell it to others at a reasonable price.

However, Lu Zhou did not choose to do this.

First of all, the design and production process is really beyond his ability. Another one is that he has a very clear position on himself. As a scientific researcher, his battlefield is in the laboratory, not in the mall or in the factory.

As for how to implement the technology into industrial production, it is better to leave it to those professional engineers to design it. If you are full, you have to leave something for others to eat. To rely on patents to eat, of course, the bigger the market, the more full you will be. There is no need to hold the small peasant mentality and care about marginal interests.

At that time, it is better to use the patent fee to upgrade the equipment and reverse some technology from this battery. It is neither necessary nor efficient to conduct research and set up factories for production.

Doing research and making products are two different things, but many laymen habitually confuse them with each other. It is far more efficient to make what you are good at the best than to use a hammer to a stick.

However, although it is intended to eat patent fees, this patent fee is not so easy to get.

In order to solve the hidden problem, he had to make this thing at least once in the laboratory.

Otherwise, many things cannot be explained, not to mention that applying for patents and writing papers also need experimental data as support.

The first priority is to design the experiment.

Only when the experimental problems are solved, can he happily register for a patent, happily publish papers to pretend... Oh no, how can scientists be called pretending?

That is to contribute to the progress of science!
