Scholar’s Advanced Technological System

Chemistry is a big pit, and although it's not as big as biology and materials, it still has a lot of graduates buried in it.

One reason is that hazards, particularly organic chemistry, require frequent dealings with reagents. Don't think anything will happen if you put the safety manual on your back, and when it does, you don't even know what's going on in the reaction room?

The other is pay, and while many of the lists associated with starting pay for graduation prefer to put applied chemistry at the top of the list, in fact the situation is another one. As for why, look at the environment of the chemical industry as a whole and you'll see, no evaluation.

But the Ark felt that at least the last one, Han Mengqi had nothing to worry about.

Anyway, even if she learned chemistry, she wouldn't necessarily do it. Even if she did, she wouldn't rely on this to buy a house. Anyway, she has a rich mother...

Chen Xuexi, who was sitting as a co-pilot, guided the way, and the Ark was in charge of driving the photo, and the four of them spent the whole day in Philadelphia.

Perhaps because the atmosphere of joy diminished the depression in his heart, Han Mengqi's mood looked much better.

But the best part of the fun is Xiaotong. This little guy seems to have endless energy, and he hasn't stopped chattering all the way from beginning to end.

Because the lively and moving Xiaotong herself brings a bit of self-familiarity, she soon got acquainted with Sister Chen and Monkey, and added WeChat and QQ while resting in a fast food restaurant.

Especially when she learned that Maggie was also playing king, Xiaotong didn't even eat half the hamburger, not to mention opened the game.

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

Xiaotong said proudly: "Play and play, I'm amazing. ”

Han Mengqi continued with interest: "What part are you in? ”

“Diamonds!” Xiaotong looked confident and paused for a moment before continuing, “But for the time being, my data is still bronze, but there is no doubt that my strength already has a diamond level, getting that box is only a matter of time. ”

Han Mengqi: "…”

Hearing the conversation between the two, Chen Yushan, biting the Coke straw, held his laugh, and the canoe sitting next to him turned a white eye.

There is no doubt that she meets the “stubborn bronze” standard for stubbornness.

Other than that, it's probably just a little short...

……

With the arrival of Xiaotong, the daily life of the ark has changed too much, and the only difference to be made is that there is an extra person to look after, and where he sleeps every day, from his bedroom to the sofa.

Although his original plan was to move out of the student's apartment upon his return to Princeton, the new address had not yet been chosen.

He now has two options: a teacher's apartment prepared for him by the Princeton Institute of Higher Studies, and a second-floor small villa with front yard and garage in the middle of Princeton University and the Institute of Higher Studies.

In fact, it's a villa, it's just an elegant way of calling it, this country house is very common in the United States, and can be seen in an aesthetic show even if you haven't been there. In a country like Princeton, the average price of the house is between $200,000 and $300,000, and the rent is not expensive.

The intention of the ship is to choose the latter because parking is convenient. But the owner of Nahe is a stubborn old New York man who only sells for no rent. And the ship now has only half a million dollars, not without money, but he doesn't want half of his family to buy a house for less than a few years.

After all, he will be back in a few years, and there is absolutely no rent for buying the house.

Although other houses were considered by the Ark, they were either unsuitable or rented out, so the move was set aside.

Luckily, Xiaotong lived in the opposite place and was not impeccable. Apart from the fact that he was always holding his arm three times apart and begging him to drive himself to Philadelphia to play with his sister, the ark did not feel too troublesome during this time.

This busy and relaxing life lasted until late August, and gradually broke down with the new issue of Natural Chemistry...

……

Just after the end of the Rio Olympics in late August, the news hotspot had not yet been withdrawn from the condemnation of the black post, and a piece of news had quietly appeared on the scientific and technological panels of major newspapers.

The cause is a paper published in Nature's sub-journal Natural Chemistry.

Its headline is a simple line, but it catches the eye of all those in the industry.

There's no other reason.

Because the contributor proposed a new type of PDMS material and claimed that lithium branches could be effectively solved by spinning the material onto the surface of anodic lithium. If this paper is published in other journals, it may not even attract the attention of many people.

But this paper is a sub-issue of Nature!

The originally calm material science and battery fields suddenly caused a shock wave.

Although this is not the first time the material science community has been shocked by a "breakthrough” in lithium batteries, it is clearly different this time, because the reviewer is Professor Bawandi and, according to the reviewer's assessment, he seems to have found surprising results from repeated experiments…

Naturally, such amazing news will not simply be buried.

Less than a few days after receiving positive opinions from several industry bulls, the paper was released shortly after the main issue, Nature, and Science, conducted Highlights.

The so-called "Highlights” is probably similar to reproduction, but different from reproduction.

For example, if you publish an article in issue A, which is a major breakthrough in a certain area or direction, and it is read in issue B, the magazine will find a bull in that area to highlight the article you sent to issue in issue A in a general way in issue B (and also write your own Highlights).

This is common in both chemical and biological fields, and it is not new that articles published in the subjournal are selected by the main issue, but it is rare that Highlights is carried out by Nature and Science at the same time.

The attitude of academia towards this thesis can be described by the term "fanaticism” as opposed to the calm of industry.

If the paper were true, most of them would not benefit from it.

The reason for this is simple: industry concerns about lithium batteries are mainly focused on a range of safety issues caused by lithium branches. If the lithium-crystal problem is resolved successfully, there is no doubt that significant R&D funding will flow into this area.

Even if so many laboratories studying anode materials were cut off, more money and topics would flow in.

So in less than a week, almost 80 percent of the laboratories studying lithium batteries have repeatedly experimented with this paper.

This momentum quickly attracted the attention of the press.

Journalists from the Radio Télévision de Colombia science and technology programme conducted an interview with Professor Ross Creel at Cornell University.

Unfortunately, by the time the Colombian television journalist arrived, Professor Creel's lab had repeatedly experimented with the paper, and it was in its final stages.

When asked about the significance of the technology, Professor Claire said with seriousness.

“… our research team is repeating the experiment, and if it wasn't an accident, the technology would undoubtedly change the look of the industry as a whole. ”

“Because neither lithium-sulfur batteries nor lithium-air batteries at the conceptual stage can bypass the branch crystal problem. Conversely, lithium-crystal problems can be solved on anode materials, and we don't even have to make major changes to previous designs to replace the anode materials directly. ”

Professor Claire answered, flashing exciting lights in the eyes of journalists.

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

“But Professor Claire, based on our interview with the former head of the IBM Group Lithium Air Battery Project, what do you think of the industry's pessimism about this technology? ”

Professor Claire thought about it and replied: "Pessimism is normal, because every now and then laboratories claim to have solved the lithium branches problem, and it is necessary to be cautious about new technologies. To be honest, even now, I remain skeptical, because the solutions that the contributors have mentioned in their papers are not novel or even a little outdated. ”

The reporter immediately asked, “Why do you say that? ”

Professor Claire: "Because our prevailing practice now is to increase the viscosity of electrolytes, even directly using solid materials. Or do a carbon material structure on the lithium anode, limit the appearance of lithium metal after growth when discharging, and also ensure that all lithium enters the cathode after the anode structure does not collapse when charging. Professor Lu's design for coating anode materials has actually been tried countless times in many laboratories 20 years ago. And..."

Reporter: "And? ”

Professor Claire shrugged: “And he's a math professor. I don't know about computing materials, an emerging discipline that has only recently emerged, but even so, I do know that a lot of things are not enough to model. ”

Yet at this point, in the lab behind me, a cheer suddenly sounded.

After hearing the voice, Professor Claire and the reporter were both stunned.

Reporter: "What happened? ”

Professor Claire looked at his assistant and looked at the reporter strangely.

“I don't know… maybe it worked? ”
