Scholar’s Advanced Technological System

MIT, a materials science laboratory.

Professor Monty G. Bavandi, sitting at his desk, is drinking coffee while browsing new articles on Arxiv.

As a big actor in the field of nanochemistry, this big man 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 has attracted widespread attention from Silicon Valley high-tech companies.

Although this technology is still a long way from being accepted by industry in terms of commercialization, the potential it has shown is already quite "black technology".

Many people comment that the distance between him and the Nobel Prize is only one commercialization of quantum dot technology. When will quantum dot technology really become widespread and change the world, then the Nobel Prize will not be far behind.

This day may be ten years later, or maybe twenty years later. The industry has begun to embrace these technologies, and it is expected that this technology will first be used in displays and will eventually change the face of the future semiconductor industry.

But no matter how far it is from commercialization, he already owns four companies through the technology. Other professors may worry about research funding, but he has become a real boss and is doing experiments at his own expense.

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

"Lithium dendrite?"

Looking at the e-mail on the screen, Professor Bavandi's eyebrows raised a look of interest.

Touching his chin, he shouted back to his assistant, "Latis, help me get a sandwich."

"Okay, professor."

The beautiful lady in a white coat got up and went outside, and soon the sandwich with bacon was delivered.

Professor Bawangdi, sitting in front of the computer, was enjoying his breakfast while continuing to look down the text of the email.

To be honest, some people claim that the lithium dendrite problem has been solved, and he is not convinced.

Although he did not make lithium batteries, some people in his team have studied this, and he has also heard about it.

The best research and development done in this area is probably the American and British Oxis, but I have not heard of any special progress recently. Samsung, as always, registered patents madly, but no one saw them really make a big news.

To say that the only "progress" may be a professor at MIT last year and found that fixing sulfur in mesoporous carbon materials and using a special electrolyte can effectively inhibit the growth of lithium dendrites.

However, in the end, it turns out that this is just a beautiful misunderstanding. If lithium dendrites were so easy to solve, IBM, which had threatened to use supercalculation to calculate the distribution of each ion path, would not hate divestment.

Back to this paper, if this paper was written by someone else, Professor Bavandi may be thrown aside by looking at it, but the problem is that the contributor of this paper is very interesting, although he is famous but not an electrode Insiders in the materials field, but a professor of mathematics at Princeton University.

"Improving the" breathability "of negative electrode materials through PDMS material films and suppressing the growth of lithium dendrites ... This is not a new idea. The performance on the SEM electron micrograph is surprising, and it is not very like P. . "

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

In the image, the images of the negative electrode material based on several charge and discharge cycles show that the negative electrode material under the PDMS film does not form the deadly white branch, but is replaced by a layer of mossy folds, and as the charging progresses , Layer by layer.

Then comes the discharge link. Because the entire surface of the anode material is a layer of mossy wrinkles with gentle undulations in a microscopic state, there is no so-called tip region. After the discharge is completed, there is no large amount of dead lithium on the electrode. situation.

There is no doubt that these results are absolutely ground-breaking if there is no fraud.

The only flaw is that those folds will also affect the battery life and performance, but compared to the dendrite stuck on the bottleneck of lithium battery technology, this flaw can be said to be trivial.

Forefinger tapping gently on the table, Professor Bavandi thought for a long time.

The dissertation is a good article, and the data and picture evidence listed in it are not faulty, but because this breakthrough is so significant, he is now undecided like the editor of Nature.

After thinking about it for a long time, suddenly Professor Bavandi moved a little in his heart and shouted back.

"Latis, I will send an experiment report to your mailbox in a while, and you will let Isaac follow the experiment report. Remember to tell him that this is his experimental task this week."

"Good professor."

Get it.

There was a smile on the corner of Professor Bavandi's mouth.

Isaac is a master's student he is studying, which is exactly the direction of the battery.

The experiment itself is not too difficult and can be tested within three days.

Although the general reviewer is not responsible for repetitive experiments, in order to satisfy his own curiosity, he decided to ask a few master students to do it.

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

If the lithium dendrite is really solved, then he can be regarded as witnessing history.

...

When Peer Review was published in Natural Chemistry, Lu Zhou was not idle.

Three masters were summoned to his office again, and this time Lu Zhou issued a book list to everyone.

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

However, he asked them to have all of the contents of these six books within one and a half months, that is, before September.

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

For a student who has just completed their undergraduate studies, completing this task is definitely not easy, but it is not absolutely impossible. Many of them were involved in the undergraduate level, but they did not go deeper.

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

It is impossible to participate in his project without paying any sweat.

It is foreseeable that they will have a very full life this summer.

As the mission went on, a week passed. Lu Zhou, who was writing an opening report in the office, suddenly received a call from China.

On the phone, Xiao Tong shouted excitedly.

"Brother Brother! I got admitted!"

Lu Zhou smiled slightly at Xiao Tong's excited voice.

"Congratulations!"

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

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

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

When he heard that the little guy didn't even want a gift, Lu Zhou immediately stunned.

"... What's so fun about Princeton."

There doesn't seem to be any particularly fascinating scenery here, except for Carnegie Lake, at least in his opinion.

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

Xiaotong said glumly, "It's so boring to stay at home ~ www.readwn.com ~ I want to come out and walk around."

Lu Zhou thought about it and thought it made sense.

It is rare to spend such a relaxing and comfortable holiday to play games at home, which is a waste of life. It ’s okay to go out and have a look at myself, it's more reassuring than going out alone.

Lu Zhou: "Let's do it ... Will I get a visa myself?"

When he saw his brother Songkou, Xiaotong said immediately: "Of course it will. I already got my passport! I will go to Shanghai to get a visa the day after tomorrow!"

It turned out that this little guy had already planned.

Lu Zhou smiled and shook his head.

"Let's go. I bought the ticket for you. Just board the plane. I'll pick you up here."

Xiaotong cheered from the other end of the phone.

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

"Rolling, little with me."

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

Just then, he suddenly remembered something.

Speaking of which, I don't know how well Han Mengqi did the test.

Even though he had n’t been a part-time tutor for a long time, but after all he was a student brought out by himself, the job really helped him a lot, and Lu Zhou was still a little concerned about her situation.

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

Opening WeChat, Lu Zhou sent a message.

[Has the offer letter been received? 】

Rarely, he waited for a long time without seeing a reply.

Thinking that she probably hadn't seen it, Lu Zhou put her phone next to it.

I wish she had been admitted to her ideal university.

With a silent blessing in his heart, Lu Zhou set aside this matter for a while and continued to work at hand.
