Scholar’s Advanced Technological System

The next afternoon, the mrs conference lithium battery special report hall was crowded and packed.

Many people came to the venue early, waiting in advance for the beginning of the report.

Standing at the door of the lecture hall, watching the crowd of black people inside, Lu Zhou could not help but numb the scalp.

I don't know why, he suddenly had a bit of admiration for Professor Sarrot who met yesterday.

In a sense, for the rice bowls of ten or twenty researchers in the lab, in order to get hundreds of millions of research funds, holding imperfect projects, running here and tearing with their peers, it is necessary The courage.

In this line, the peers are the family, and the different lines are also the family.

Take the lithium-sulfur battery in this direction, do the manganese dioxide nano-layer and do the polymer solid electrolyte, it seems that it is something that the gossip can't beat, but in fact it is to solve the shuttle of the lithium-sulfur battery. effect.

In fact, everyone's technology has black spots, just a few questions.

Everyone wants the industry to adopt their own solutions, invest in their own research, and let their technology "live."

In the same way, Lu Zhou’s thesis, although the concept of lithium battery ushered in the spring, has caused many project teams to be cut off, so many researchers have lost their jobs. I believe many people are behind the scenes. Pass him.

But what surprised Lu Zhou was that when he stood on the podium and glanced down, he did not see the kind of person who was obviously waiting to find him.

At least he can see the front row.

Instead, that pair of sights are full...

look forward to?

Although I suspect that I am wrong, the report is about to begin.

Set the gods, Lu Zhou walked onto the podium, plugged the u disk into the multimedia platform, and then signaled the staff next to him to drag three whiteboards.

The usual material science report will not use so many books, but his report will naturally be based on mathematics.

Facing the venue that had gradually quieted down, Lu Zhou tried the microphone and said it in a concise manner.

"I have made a fairly complete description of the properties and preparation methods of the modified polydimethylsiloxane film. I believe that you have seen it before this report, so I won't go into details here."

After a pause, Lu Zhou continued, "And compared to the pdms film, I believe that you are more interested in how I found it."

Upon hearing this sentence, many people sitting under the stage nodded.

Sitting here, not all of them are researchers or business representatives of lithium battery interests. Many of the big cattle in the field of organic materials are sitting here at this moment.

For people of different research directions, what they are more curious about is not the pdms material itself, but how Lu Zhou locked the material by establishing mathematical models.

Responding to the look of the pair of expectations, Lu Zhou did not waste time on the opening, directly into the topic.

“In the initial stages of deposition, lithium ions typically acquire electrons and deposit them on the current collector, which is considered to be a heterogeneous nucleation behavior. Because of this initial nucleation, the final lithium deposition pattern It has a decisive influence, so my initial idea is to solve the problem of irregular growth of lithium dendrites by taking the initial stage of the nucleation stage as an entry point."

"After sem electron microscopy, we can see the root of the crystal nucleus in the electrolyte. We can see it as a spherical cap-shaped nucleus deposited on a flat substrate. Abstract, it is a three-dimensional spherical surface. We can set θ as the contact angle, r Is the radius of curvature, a is the radius of the contact surface, and γ is the surface tension..."

Some things are said to be unclear.

Lu Zhou picked up the marker and got a book on the whiteboard.

[sv=(π/3)(2+cosθ)(1-cosθ)2]

[?gt=(?gf+zfη/Ω)svr3+γsar2+(γsn-γse)πr2sin2θ]

[...]

The formula on the whiteboard is more and more written.

The nib jumps on the whiteboard, and the line-by-line formula jumps out.

The entire mathematical model is like a well-constructed skeleton that supports the blood and flesh of the research.

Every detail of it has already been clear, even if it has not been deliberately recited, Lu Zhou can smoothly conduct on-site deduction.

The researchers sitting under the table were nailed straight to the whiteboard, for fear of missing a detail.

Even so, there are very few people who can keep up with his rhythm.

Some thoughts of not being able to keep up with Lu Zhou, Professor Krell took a deep breath, and some worried left-handedly looked forward to it.

When he noticed, Professor Bwandi, who was sitting next to him from the Massachusetts Institute of Technology, was holding his arms and looking at the whiteboard with ease. He couldn’t help but lower his voice.

"Do you understand?"

Professor Bawdi did not answer this question directly.

After pondering for a moment, he gave his evaluation in a relaxed tone. "Of course, it's a very interesting way."

Professor Bwandi is studying quantum dot technology, not just chemistry, but also about condensed matter physics.

Once the field of study involves physics, mathematics is not good, but it will be strange.

After hearing the evaluation of Professor Bwindi, Professor Krell looked helpless.

The report will go to this stage, a lot of things on the whiteboard, he has begun to understand.

He didn't understand mathematics, but he didn't study it so deeply. After all, material science is an experiment-based discipline, and most of the data is made, not calculated.

However, some people have told him that the position of computational materials science in the materials science laboratory is not only to assist, but also to Kerry. In addition to doubting his life, he seems to have no better way.

Perhaps he has to take time to study it.

Time passes by.

Entering the state of Lu Zhou, it seems to return to Princeton's classroom, and the audience under the audience are his students, listening to his doctrine.

For the eyes of those who are seeking knowledge, Lu Zhou also responded to the greatest enthusiasm and spread his own doctrine.

[ts=πd(c0ezc/2j)2({ua+uc}/ua)......]

When the last line of calculations was written, Lu Zhou stopped the pen in his hand.

Two steps back, he looked up and down at the whiteboard in front of him and did not speak.

Staring at the back of this is not tall but unusually stalwart, the audience is silent, the birds are silent, for fear that the breathing will be louder, interrupting the thinking of this big man.

It’s been five minutes.

Lu Zhou finally turned around and placed the marker in his hand on the multimedia platform.

"The basic situation is like this."

"The next step is the questioning session. If there is anything you don't understand, you can ask."

There was still silence in the venue.

No one stood up, no one raised their hands, and no one even snorted.

Even the most inferior expert, at this moment, swearing, people can not help wondering if this is really the scene of the mrs autumn party.

Gradually, the silence finally broke.

After returning to the people of God, I began to applaud.

"Hey..."

With the first one, there is a second one.

Soon the thunderous applause filled the venue, like a gust of wind and rain.

Looking at the crowd applauding, Lu Zhou squatted slightly.

What surprised him was not applause, but no one stood up and asked questions.

Thinking of this, Lu Zhou’s expression can’t help but be a bit weird.

tentatively……

Just when they all understood it.

Anyway, after the meeting, the American Materials Society will print a thick collection of papers like bricks. If they are interested, they will naturally study the things he has said.

As for what he did, he has already finished.

Lu Zhou indicated to the staff next to the meeting that the meeting was over.

However, when he was about to unplug the u disk, he suddenly remembered one thing.

"Oh yes, I almost forgot, ppt has not finished."

I was too embarrassed to say that I almost forgot the "righteous thing".

Lu Zhou pressed the button on the laser pointer and quickly passed the rest of the ppt.

"With regard to the modified pdms film, there is nothing to say. In the past two and a half months, I have done six sets of experiments here. The macroscopic conditions inside the battery and the sem image of the cross section of the negative electrode material under microscopic conditions after the Coulomb cycle of 1000 to 2000 respectively."

This experiment is not difficult, but it is very troublesome, especially taking time.

But in order to dispel the concerns of the industry, this experiment is a must.

Ppt was fixed on the penultimate page, stopped the show of the boat, paused and continued.

"I believe that there should be many people who are more interested in this."

There are indeed many people interested.

When I saw the 2000 Coulomb cycle, the inside picture of the dirty battery case, the business representatives sitting in the back row and whispering the whole report, staring at ppt's eyes straightened.

The route to the New World is drawn on that picture, and the "treasure" they have always dreamed of has never been so close.

There is the future.

Now, someone has already indicated the course for them...
