Chemistry is a big pit. Although this pit is not as big as creatures and materials, it still has many graduates buried inside. .

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

The other one is salary, although many of the lists related to graduation starting salary like to put the application chemistry ahead, but in fact the situation is another look. As for why it is said, look at the overall environment of the chemical industry, you will know, do not evaluate.

However, Lu Zhou feels that at least the last one, Han Mengqi does not have to worry.

Anyway, even if she learned chemistry, she would not necessarily do this. Even if she did this, she would not rely on this to buy a house. Anyway, she has a rich mother...

Guided by Chen Xuejie, who was sitting in the co-pilot, Lu Zhou was responsible for driving and taking pictures. Four people played in Philadelphia for a whole day.

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

But the happiest thing to play is a small beggar. This little guy seems to have endless energy, and he has never stopped from the beginning to the end.

Because the lively and active little scorpion itself has a familiar character, so she soon became familiar with Chen Xuejie and Mengqi, and added WeChat and qq when they were resting in the fast food restaurant.

Especially when she learned that Meng Qi was also playing the king, Xiao Yan didn't even eat half of the burgers, and opened the game.

Looking at the game interface in Xiaoyan’s mobile phone, Han Mengqi asked unexpectedly: “You also play the king?”

Xiao Yan proudly said: "Play and play, I am amazing."

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

"Diamond!" Xiao Yan looked confident and paused for a while and continued. "But for the time being, my data is still bronze, but there is no doubt that my strength has a diamond level. It is only a matter of time to get that frame. ""

Han Mengqi: "..."

When I heard the conversation between the two, Chen Yushan, who was biting the cola pipette, smirked, and Lu Zhou, who was sitting next to me, rolled her eyes.

There is no doubt that she is absolutely in line with the "stubborn bronze" level.

In addition to this, the difference is probably a little worse...

......

With the arrival of Xiaoyan, Lu Zhou’s daily life has changed too much. The only difference is that there is an additional person to take care of, and the position where he sleeps every day, from his own bedroom. It became a sofa.

Although his original plan was to return to Princeton, he moved out of the student apartment, but the new address has not been selected.

He now has two options, one is a teacher's apartment for the Princeton Institute of Advanced Studies, and the other is a two-story cottage with a front yard and garage in the middle of Princeton University and the Institute of Advanced Studies.

In fact, it is a villa, just a kind of elegant name. This kind of country cottage is very common in the United States, even if you have not been there, you can see it in the American drama. In the countryside of Princeton, the average price of such a house is between $200,000 and $300,000, and the rent is not expensive.

Lu Zhou’s original intention was to choose the latter because parking is convenient. But the owner of the house is a stubborn old man in New York, only selling and not renting. Lu Zhou now has only $500,000. Although he doesn't have the money to buy it, he doesn't want to buy half of his house to buy a house that can't live for a few years.

After all, he will return to China after a few years, and there is absolutely no cost to rent a house.

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

Fortunately, Xiao Yan was not picky about the place where he lived. In addition to pulling his arm every other time, he begged him to drive to Philadelphia to find a school sister to play. During this time, Lu Zhou did not feel too much trouble.

This busy life is interspersed with a leisurely life, which lasts until late August. With the release of the new issue of Natural Chemistry, it gradually breaks down...

......

In late August, the Rio Olympics had just ended, and the news hotspot had not been withdrawn from the condemnation of the black whistle. A piece of news quietly boarded the technology panel of the major newspapers.

The cause is a paper published in the journal Nature, Nature Chemistry.

Its title is only a simple word, but it captures the eyes of all industry insiders.

There is no reason for him.

Because 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 this paper is published in other journals, it may not even attract the attention of many people.

However, the publication of this paper is a sub-publicicle of Nature!

The original material science and battery field, which was calm and calm, suddenly set off a storm.

Although the material science community is not the first time to be shocked by the “breakthrough” of lithium batteries, this time is obviously different, because the reviewer is Professor Bwandi, and according to the reviewer’s evaluation, he seems to repeat the experiment. Got amazing discoveries...

Such amazing news will naturally not be buried.

A few days after the publication of the paper, after receiving affirmative opinions from several big bulls in the industry, they were highlighted by the main issue "Nature" and "Science" which were released shortly afterwards.

The so-called "highlights" is probably similar to reprinting, but it is different from reprinting.

For example, if you published an article in a journal, this article has a major breakthrough in a certain field or direction. When you look at it in the journal b, the magazine will find a section of the journalist who sent you in the journal. The highlights of the article are summarized in the journal b (and some are writing their own highlights).

This situation is more common in the two fields of chemistry and biology. It is not a new thing to be published in the main journal, but it is rare to be highlighted by Nature and Science. of.

Compared with the calmness of industry, the attitude of the academic community to this paper can be described as the word "fanatic".

If this paper is true, most of them will not suffer from the loss of interest, but will benefit from it.

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

Even if there are so few laboratories studying negative electrode materials that have been cut off, more funds and issues will come in.

Therefore, in just a short week, almost 80% of the labs that study lithium batteries have repeated experiments on this paper.

This grand occasion quickly caught the attention of the press.

A reporter from the Columbia Radio and Television Science and Technology section gave an interview and interviewed Professor Roth Crael at Cornell University.

Coincidentally, when the Colombian TV reporter arrived, Professor Krell’s laboratory was just repeating the experiment and it was in its final stages.

When asked about the meaning of the technology, Professor Krell said with a serious face.

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

"Because neither the lithium-sulfur battery nor the lithium-air battery at the conceptual stage can solve the problem of dendrites. In turn, the problem of lithium dendrite can be solved on the negative electrode material, we don't even have to make too much design for the past. Great changes, just replace the negative material directly."

Professor Krell’s answer made the reporter’s eyes sparkle with excitement.

There is no doubt that the big news he wants is right in front of him.

“But Professor Krell, according to the feedback we received from the head of the lithium battery project of the ibm Group, is that the industry is pessimistic about this technology. What do you think about this?”

Professor Krell thought and replied: "Peer is very normal, because every once in a while, the laboratory claims to solve the problem of lithium dendrites. It is necessary to be cautious about new technologies. To be honest, even now, I still remain skeptical, because the solution ideas mentioned by the contributors in the paper are not new or even outdated."

The reporter immediately asked: "Why do you say this?"

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

Reporter: "And?"

Professor Crael shrugged: "And he is a mathematics professor. I don't know about the emerging disciplines that have recently emerged as computational materials, but even so I know that a lot of things are not enough to build models."

However, at this moment, in the laboratory behind it, a cheering sound suddenly sounded.

After hearing this voice, Professor Krell and the reporters all succumbed.

Reporter: "What happened?"

Professor Krell and his assistant looked at each other and looked at the reporter with a strange look.

"I don't know... maybe it's a success?"
