Scholar’s Advanced Technological System

Chemistry is a big pit. Although this pit is not as big as biology and materials, many graduates are still buried in it.

One reason is danger, especially organic chemistry, which requires frequent dealing with reagents. Don't think that there will be no accident when you back down the safety manual. When the accident happens, you don't even know what happened in the reaction room?

Another is salary. Although many lists related to starting salary for graduation like to apply applied chemistry, the situation is actually different. As for why to say so, just look at the overall environment of the chemical industry, and don't evaluate it.

However, Lu Zhou felt that at least the last one, Han Mengqi need not worry.

Anyway, even if she studied chemistry, she won't necessarily do it in the end. Even if she does this, she won't rely on this to buy a house. Anyway, she has a rich old lady ...

Sister Chen Xue, who was sitting in the co-pilot, showed the way. Lu Zhou was in charge of driving and taking pictures. Four people played in Philadelphia all day.

Perhaps because the joyful atmosphere dilutes the depression in my heart, Han Mengqi's mood looks a lot better.

But it was Xiao Tong who had the most fun, this little guy seemed to have endless energy, and never stopped from beginning to end along the way.

Because Xiaotong, who is lively and active, has a familiar personality, she soon became familiar with Chen Xue and Meng Qi, and added WeChat and QQ to each other while resting in a fast food restaurant.

Especially when she learned that Meng Qi was also playing King, Xiao Tong did not even eat half of the burger, and opened the game without saying a word.

Looking at the game interface in Xiaotong's phone, Han Mengqi asked a little unexpectedly: "Do you also play the king?"

Xiaotong proudly said, "Play, play, I'm terrific."

Han Mengqi continued to ask with interest: "What grade do you have?"

"Diamond!" Xiaotong continued with a look of self-confidence and paused. "But for the time being, my data is still bronze, but there is no doubt that my strength has already reached the diamond level. It is only a matter of time before I get that . "

Han Mengqi: "..."

Hearing the conversation between the two, Chen Yushan biting a cola straw smirked, and Lu Zhou sitting next to him rolled his eyes.

There is no doubt that regarding stubbornness, she absolutely meets the level of "stubborn bronze".

In other parts, it is probably a bit worse ...

...

With Xiaotong's arrival, Lu Zhou's daily life has changed too much. The only difference is that there is one more person to take care of and the place where he sleeps every day, changing from his bedroom. It became a sofa.

Although he originally planned to move out of the student apartment after returning to Princeton, the new address has not yet been selected.

He now has two options, one is the teacher's apartment prepared for him by the Princeton Advanced Institute, and the other is a two-storey cottage with a front yard and a garage located between Princeton University and the Advanced Institute.

In fact, it is a villa, which is just a gentle name. This kind of country house is very common in the United States, and you can see it in American dramas even if you have never been there. In a country like Princeton, the average price of such a house is 200,000 to 300,000 US dollars, and the rent is not expensive.

The original intention of Lu Zhou was to choose the latter, because parking was convenient. But the homeowner is a stubborn old man in New York who only sells without rent. Lu Zhou now has only 500,000 US dollars. Although it is not that he has no money to buy it, he does not want to use half of his net worth to buy a house that will not live for a few years.

After all, he will be returning to China in a few years. There is absolutely no cost-effective way to buy a house.

Although Lu Zhou also considered other houses, they were either inappropriate or rented out, so the move was put on hold.

Fortunately, Xiao Tong was not picky about where he lived, except that he always pulled his arm every three minutes and begged him to drive himself to Philadelphia to find his sister to play, but Lu Zhou didn't feel too troublesome during this time.

This busy life is interspersed with a leisurely life, which lasted until late August. With the publication of the new issue of Natural Chemistry, it gradually broke ...

...

In late August, the Rio Olympics has just ended, and the news has not yet withdrawn from the condemnation of the black whistle, and a piece of news has quietly appeared on the technology panels of major newspapers.

The cause was a paper published in the journal Nature Chemistry.

Its title is a single line of words, but it has caught the attention of all people in the industry.

No reason for him.

The contributor proposed a new type of PDMS material, and claimed that by spin-coating the material on the surface of the negative electrode lithium, the problem of lithium dendrite can be effectively solved. If the paper was published in another journal, it might not even get noticed.

However, this article is published as a subsidiary of Nature!

The fields of materials science and batteries, which were originally calm, suddenly caused a rough sea.

Although it is not the first time that the material science community has been shocked by the "breakthrough" of lithium batteries, this time is obviously different, because the reviewer is Professor Bavandi, and according to the reviewer's evaluation, he seems to have passed repeated experiments. Got amazing discoveries ...

Such amazing news, naturally, will not simply be buried.

A few days after the dissertation was published, after receiving the positive opinions of several industry giants, it was highlighted by the main journals Nature and Science that were released shortly after.

The so-called "Highlights" are probably similar to reprints, but different from reprints.

For example, if you publish an article in A journal, this article has a major breakthrough in a certain field or direction, and if it is regarded by B journal, the magazine will find a cattle person in this field to send you the article in A journal The highlights of the article are summarized and published in the B journal (also some have written their own Highlights).

This situation is more common in the fields of chemistry and biology. It is not a new thing to publish articles published in sub-journals by the main issue, but it is rare to have Highlights performed by Nature and Science at the same time. of.

Compared to the calmness of the industrial world, the attitude of the academic world to this paper can be described by the word "fanaticism".

If this thesis is true, most of them will not be harmed because of this, but will benefit from it.

The reason is very simple. The industrial industry's concerns about lithium batteries are mainly focused on a series of safety issues caused by lithium dendrites. If the problem of lithium dendrites can be resolved smoothly, there is no doubt that a large amount of research and development funds will flow into this area.

Even if there are several laboratories for anode materials that are cut off, more funds and topics will flow in.

Therefore, in less than a week, almost 80% of the laboratories studying lithium batteries have carried out repeated experiments on this paper.

This grand occasion quickly caught the attention of the press.

A reporter from CBS's science and technology section did an interview with Professor Rose Krell at Cornell University.

Coincidentally, when a reporter from Columbia TV arrived, Professor Creel's laboratory was just repeating the experiment, and it had reached the final stage.

When asked about the significance of the technology, Professor Kreer said solemnly.

"... Our research team is repeating the experiment. If this is not an accident, this technology will undoubtedly change the face of the industry."

"Because both the lithium-sulfur battery and the lithium-air battery at the concept stage cannot avoid the dendrite problem. In turn, the lithium dendrite problem can be solved on the anode material, and we don't even have to make too much of the previous design. Large changes, just change the anode material directly ~ www.readwn.com ~ Professor Krell's answer made the reporter's eyes sparkle with excitement.

There is no doubt that the big news he wants is in sight.

"But Professor Kreer, according to the feedback we interviewed from the former leader of the lithium air battery project of the IBM Group, the industry is pessimistic about this technology. What do you think of this?"

Professor Creel thought for a while and replied, "Pessimism is normal, because every so often the lab claims to solve the lithium dendrite problem, and it is necessary to be cautious about new technologies. Honestly, even now, I remain skeptical, because the solution that the contributors mentioned in the paper is not novel or even a bit outdated. "

The reporter immediately asked, "Why do you say that?"

Professor Krell: "Because our current mainstream approach is to increase the viscosity of the electrolyte, even directly using solid materials. Or make a carbon material structure on the lithium negative electrode, which limits the appearance of lithium metal growth during discharge, and also when charging. It can ensure that the negative electrode structure does not collapse after all the lithium has entered the positive electrode. In fact, the design of the coating film on the negative electrode material used by Professor Lu has actually been tried many times in many laboratories 20 years ago. And ... "

Reporter: "And?"

Professor Krel shrugged. "And he is a professor of mathematics. I don't know about the emerging discipline of computational materials that has only recently emerged, but even so I know that many things are not enough to just model."

Just then, cheers suddenly sounded in the laboratory behind.

After hearing this voice, Professor Creel and the reporter hesitated.

Reporter: "What happened?"

Professor Crare looked at his assistant and looked at the reporter with a strange look.

"I don't know ... maybe it was successful?"
