Massachusetts Institute of Technology, a materials science laboratory. .

Professor Monk G. Bwandi, sitting at the desk, is drinking coffee casually while browsing the new articles on arxiv.

As a big bull in the field of nanochemistry, this big cockroach has recently become the limelight.

Not long ago, the journal "as-nano" published his research paper on pbs quantum dot thin film solar cells, which attracted widespread attention from Silicon Valley high-tech companies.

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

Many people have commented that the distance between him and the Nobel Prize is only a commercialization of quantum dot technology. When the quantum dot technology is truly popular and changes the world, the Nobel Prize is not far off.

This day may be ten years later, maybe twenty years later, it will not be too far away. The industry has begun to accept these technologies slowly, and it is expected that this technology will be used first on displays and will eventually change the face of the semiconductor industry in the future.

But no matter how far away from real commercialization, he has owned four companies through the technology. Other professors may be worried about the research funding, but he has become the real boss, and is doing his own experiments.

Just then, in his mailbox, he suddenly received an email from Nature.

"Lithium dendrites?"

Looking at the mail on the screen, Professor Bwindi's eyebrows provoked a look of interest.

Touching his chin, he turned back and shouted at his assistant. "Lattis, help me get a sandwich."

"Okay, Professor."

The beautiful woman in white coat got up and went outside, and soon the sandwich with bacon was sent over.

Professor Bwandi, sitting in front of the computer, continued to enjoy the breakfast while continuing to follow the text on the mail.

To be honest, some people claim to have solved the problem of lithium dendrites. He does not believe it.

Although he is not a lithium battery, some people in his team have studied this piece, and he has also heard about it.

The best in this piece of research and development is probably the US sion and the British oxis, but I have not heard of any special progress recently. Samsung has been madly registering patents as always, but no one has seen them really make a big news.

To say the only "progress", it may be that a professor at the Massachusetts Institute of Technology last year found that fixing sulfur in mesoporous carbon materials, combined with special electrolytes, can effectively inhibit the growth of lithium dendrites.

However, in the end, the facts prove that this is just a beautiful misunderstanding. If the lithium dendrite is so easy to solve, it has been threatened to use the calculation of the ibm of the calculation of the path of each ion, and it will not divert funds.

Returning to this paper, if this paper is written by someone else, Professor Bawdi may be thrown aside when he looks at it, but the problem is that the contributor to this paper is very interesting. Although he is famous, he is not an electrode. An industry insider in the field of materials, but a professor of mathematics at Princeton University.

"Improve the 'breathability' of the negative electrode material through the pdms material film, and inhibit the growth of lithium dendrites... This is not a novel idea. The performance on the SEM is very different, and it is not quite like p. ""

“Computational materials science has this ability? It’s unheard of.”

In the image, the image of the negative electrode material according to several charge and discharge cycles shows that the negative electrode material located under the pdms film does not form the deadly white tree scorpion, but instead is a layer of mossy pleats, and with charging , layer by layer.

Then there is the discharge link. Since the surface of the entire negative electrode material is a layer of undulating mossy folds under the microscopic state, there is no so-called tip region, and after the discharge is finished, there is no large amount of dead lithium residue on the electrode. situation.

There is no doubt that these results are absolutely groundbreaking if there is no fraud.

The only fly in the ointment is that those folds will also affect the battery life and performance, but compared to the dendrites stuck in the lithium battery technology bottleneck, this can be said to be negligible.

The index finger tapped on the table, and Professor Bawdidi thought for a long time.

The paper is a good article, and the data and photo evidence listed in it are not picking up, but because this breakthrough is so great, he is now as unconstrained as the editor of Nature.

I thought about it for a long time. Suddenly, Professor Bwandi’s heart moved slightly and turned back.

"Latis, I will send an experimental report to your mailbox in a moment. You let Isaac do it according to the experimental report. Remember to tell him that this is his experimental task this week."

"Good professor."

Get it done.

Professor Bwandi’s mouth evoked a smile.

Isaac is the master student he brought, and the research is exactly the direction of the battery.

The experiment itself is not too difficult, it can be tested within 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 students to do it.

Anyway, he has the equipment, and the material can't cost a few dollars.

If he really solved the lithium dendrites, then he can be seen as a witness to history.

......

Just when Peking University conducted a peer review on Natural Chemistry, Lu Zhou was not idle.

Once again, three masters were summoned to his office. This time, Lu Zhou sent a list of books to everyone.

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

However, he asked them to thoroughly understand the contents of these six books within a month and a half, that is, before September.

At that time, he will ask questions from the contents of these six books to examine their learning.

For a student who has just completed his undergraduate studies, completing this job is definitely not an easy task, but it is not absolutely impossible. A lot of content they have been involved in the undergraduate stage, but did not go deep into it.

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

It is impossible to participate in his subject, it is impossible to pay a little sweat.

It is foreseeable that they will be very fulfilling this summer.

As the task was arranged, it took a week. Lu Zhou, who was writing the opening report in the office, suddenly received a call from China.

On the other side of the phone, Xiao Yan shouted excitedly.

"Older brother! I am admitted!"

Hearing the excited and excited voice of Xiao Xiao, Lu Zhou smiled slightly.

"Congratulations!"

Xiao Yan asked pitifully: "Brother, can I ask you something?"

Lu Zhou said: "Say, what gift do you want? I will send it to you."

Xiao Yan shook his head and pity: "I don't want a gift, I just want to come to Princeton to find you!"

Upon hearing this little guy didn't even want a gift, Lu Zhou suddenly fell.

"...Princeton has something to play with."

There seems to be no particularly fascinating landscape except for a Carnegie Lake, at least in his opinion.

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

Xiao Yan said with a sullen mood: "It’s too boring to stay at home, I want to go out and walk."

Lu Zhou thought about it and thought it made sense.

It’s a waste of life to put a vacation that is so easy and comfortable to play at home. It’s good to go out and walk, and it’s better to watch it out than to go out alone.

Lu Zhou: "That's it... can I apply for a visa?"

See the old brother Songkou, Xiao Yan immediately said: "Of course, my passport has already been obtained! Go to Shanghai to apply for a visa the day after tomorrow!"

It turned out that this little guy had already planned it.

Lu Zhou smiled and shook his head.

"That's all, the ticket I bought for you, you just take the plane, here I pick you up."

There was a small cheer from the phone.

"Yeah! Brother is the best! Hey, what?"

"Rolling, less and my skin."

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

Just then, he suddenly remembered one thing.

Speaking of it, I don’t know how Han Mengqi’s test is done.

Even though he has not been a part-time tutor for a long time, but after all, he is a student who brought himself out. That job has really helped him a lot. Lu Zhou still cares a little about her situation.

After the college entrance examination was over, he had never asked her about her grades. Now that the admission notice has come down, he wants to know if she has admitted to her ideal university.

Open WeChat, Lu Zhou sent a message to the past.

[Is the admission notice received? 】

Very rare, he waited for a while and didn't see a reply.

Thinking about her probably did not see, Lu Zhou put the phone next to it.

I wish she had a college that was admitted to her ideals.

In the heart, I silently blessed a sentence, Lu Zhou temporarily put this matter aside and continued to work on his hands.
