Massachusetts Institute of Technology, a materials science laboratory.

Sitting at his desk, Monchi Professor G. Bawandi, sipping a coffee leisurely, is browsing a new article on Arxiv.

As a big bull in the field of nanochemistry, this big guy has been in the limelight recently.

Not long ago, the journal "ACS-Nano" published his research paper on PbS quantum dot thin-film solar cells, which attracted a lot of attention from high-tech companies in Silicon Valley.

Although this technology is still a long way from being accepted by the industry, the potential it shows is already quite "black technology".

Many people commented that the distance between him and the Nobel Prize is only one quantum dot technology commercialization. When quantum dot technology will truly become widespread and change the world, the Nobel Prize will not be far off.

This day may be ten years from now, maybe twenty years from now, but it will not be too far away. The industry has begun to embrace these technologies, which are expected to be used in displays first and eventually change the face of the semiconductor industry in the future.

But no matter how far away he is from being commercialized, he already owns four companies through the technology. Other professors may be worried about research funding, but he has become a real boss and is doing experiments out of his own pocket.

At this moment, he suddenly received an email from "Nature" in his mailbox.

"Lithium dendrite?"

Looking at the email on the screen, Professor Bawandi's eyebrows raised a look of interest.

Touching his chin, he turned back to his assistant and shouted, "Latisse, get me a sandwich." ”

"Okay, Professor."

The Latin American woman in the white lab coat got up and went outside, and soon a sandwich with bacon was delivered.

Professor Bawandi, who was sitting in front of the computer, continued to read down the text on the email while enjoying his breakfast.

To be honest, someone claims to have solved the lithium dendrites problem, and he doesn't believe it.

Although he does not make lithium batteries, someone in his team has studied this piece, and he has also heard about it.

Probably the best R&D in this area is Sion in the United States and Oxis in the United Kingdom, but I haven't heard of any special progress recently. Samsung has been like crazy about registering patents, but no one has seen them really make big news.

The only "progress" may be that a professor at the Massachusetts Institute of Technology discovered last year that the immobilization of sulfur in mesoporous carbon materials, combined with a special electrolyte, can effectively inhibit the growth of lithium dendrites.

However, in the end, it turned out that this was just a beautiful misunderstanding, and if lithium dendrites were so easy to solve, IBM, which had threatened to use supercomputing to do distribution calculations for the path of each ion, would not have hated to withdraw its investment.

Coming back to this paper, if the paper had been written by someone else, Professor Bawandi might have looked at it twice and thrown it aside, but the problem is that the contributor to this paper is interesting, although he is not known as an expert in the field of electrode materials, but is a professor of mathematics at Princeton University.

"The 'air permeability' of the anode material is improved by the PDMS material film and the growth of lithium dendrites is inhibited...... This is not a novel idea, but the SEM image is surprising, and it doesn't look like P. ”

"Computational materials science still has this ability? Unheard. ”

In the image, based on the images of the anode material after several charge-discharge cycles, the anode material located under the PDMS film does not form the deadly white branches, but instead has a layer of moss-like folds, which are superimposed layer by layer as the charging progresses.

Then there is the discharge link, because the surface of the entire anode material is a layer of gently undulating moss-like folds in the microscopic state, there is no so-called tip area, and there is no large amount of dead lithium residue on the electrode until the discharge is over.

There is no doubt that these results would have been groundbreaking if there had been no fraud.

The only fly in the ointment is that those folds will also affect the life and performance of the battery, but compared to the dendrite stuck in the technical bottleneck of the lithium battery, this flaw can be said to be insignificant.

With his index finger tapping lightly on the table, Professor Bawandi pondered for a long time.

The paper was a good article, and the data and graphic evidence listed in it could not be faulted, but the breakthrough was so significant that he, like the editors of Nature, was now undecided.

After thinking about it for a long time, Professor Bawangdi's heart suddenly moved slightly, and he turned around and shouted.

"Latis, I'll send you a lab report in a moment, and you tell Isaac to follow it. Remember to tell him that this is his experimental assignment this week. ”

"Okay professor."

Get.

A smile tugged at the corners of Professor Bawandi's mouth.

Isaac is a master's student with him, and his research happens to be in the direction of batteries.

The experiment itself is not too difficult, and it can be tested in three days.

Although the general reviewer is not responsible for repeating the experiment, in order to satisfy his own curiosity, he decided to find a few master's students to do it.

Anyway, he has the equipment, and that little material doesn't cost a lot of money.

If lithium dendrites are really solved, then he can be regarded as witnessing history.

……

While Nature Chemistry was peer-reviewing the paper, Lu Zhou was not idle.

The three masters were summoned to his office again, and this time Lu Zhou handed out a book list to each of them.

There are not many books listed above, only six in total.

However, he asked them to thoroughly read all six books within a month and a half, that is, by September.

When the time comes, he will draw questions from the contents of these six books and examine their learning.

It's definitely not an easy task for a student who has just finished his undergraduate studies, but it's not absolutely impossible either. A lot of the content they covered at the undergraduate level, but they didn't go into it.

And now what Lu Zhou needs them to do is the process from shallow to deep.

If you want to participate in his project, it is impossible to put in a little sweat.

Predictably, they will have a fulfilling summer.

As the task was assigned, a week passed like this, and Lu Zhou, who was writing an opening report in the office, suddenly received a call from China.

On the other side of the phone, Xiaotong shouted excitedly.

"Big brother, big brother! I got in! ”

Hearing Xiaotong's excited voice, Lu Zhou smiled slightly.

"Congratulations!"

Xiaotong asked pitifully, "Brother, can I ask you for something?" ”

Lu Zhou said generously: "Say, what gift do you want?" I'll send it to you. ”

Xiaotong shook his head and said pitifully: "I don't want a gift, I just want to come to Princeton to play with you!" ”

As soon as he heard that this little guy didn't want a gift, Lu Zhou was stunned.

“…… There's something to do in Princeton. ”

With the exception of a Lake Carnegie, there doesn't seem to be anything particularly stunning, at least to him.

As for the strong academic atmosphere, it is not something that ordinary people can feel.

Xiaotong said sullenly: "It's so boring to stay at home, I want to go out for a walk." ”

Lu Zhou thought about it and felt that it made sense.

It's rare to have such a relaxing vacation and spend it at home playing games, which is a waste of life. It's good to go out for a walk, and to have her own watch, it's better than her going out to play alone.

Lu Zhou: "Okay then...... Will I be able to apply for a visa on my own? ”

Seeing that the elder brother was relieved, Xiaotong immediately said: "Of course it will, I have already got my passport!" The day after tomorrow, I will go to Shanghai to apply for a visa! ”

It turns out that this little guy has already planned it.

Lu Zhou smiled and shook his head.

"Okay, I'll buy the ticket for you, you just get on the plane, and I'll pick you up here."

Xiao Tong's cheers came from the other end of the phone.

"Yay! Dude is the best! Hee-hee, Mo-da~"

", less and my skin."

After hanging up the phone, Lu Zhou smiled and put the phone on the table.

At that moment, he suddenly remembered something.

Speaking of which, I don't know how Han Mengqi did in the exam.

Even if he has long stopped working part-time as a tutor, after all, he is a student brought out by himself, and that job has really helped him a lot, Lu Zhou is still a little concerned about her situation.

After the college entrance examination, he never asked her about her grades, and now that the admission letters have come down, he wants to know if she has been admitted to his ideal university.

opened WeChat, and Lu Zhou casually sent a message to the past.

[Have you received your acceptance letter?] 】

Very rarely, he waited for a while and did not see a reply.

Thinking that she probably didn't see it, Lu Zhou put the phone next to him.

I hope she gets into her dream university.

With a silent blessing in his heart, Lu Zhou put this matter aside for the time being and continued to get busy with the work at hand.
