In the afternoon of the next day, the lecture hall of the lithium battery topic of the MRS conference was crowded and full.

Many people arrived early and waited for the start of the presentation.

Standing at the door of the lecture hall, looking at the crowd of people inside, Lu Zhou couldn't help but feel numb in his scalp.

I don't know why, he suddenly had a sense of admiration for Professor Sarot, whom he met yesterday.

In a sense, it takes a certain amount of courage to come here and tear up with peers for the jobs of a dozen or twenty researchers in the laboratory, for millions of research funds, and for imperfect projects.

In this industry, peers are enemies, and different lines are also enemies.

Take the direction of lithium-sulfur batteries as an example, making manganese dioxide nanolayers and making polymer solid-state electrolytes seem to be things that cannot be beaten by eight poles at first glance, but in fact, they are both to solve the shuttle effect of lithium-sulfur batteries.

In fact, there are black spots in everyone's technology, it's just a matter of how much.

Everyone wants industry to adopt its own solutions, invest in its own research, and make its technology "live".

In the same way, Lu Zhou's paper, although the concept of lithium batteries ushered in the spring, also made many project teams cut off funds, so that many researchers lost their jobs for this, I believe that many people scolded him behind his back.

However, to Lu Zhou's surprise, when he stood on the podium and glanced down, he didn't see the kind of person who was obviously waiting to find fault.

At least not in the front row where he could see.

Instead, those eyes were full of ......

Expect?

I wonder if I'm mistaken, but the report is about to begin.

After settling down, Lu Zhou walked onto the podium, plugged the USB flash drive into the multimedia podium, and then motioned to the staff next to him to drag three whiteboards for himself.

The usual material science report will not need so much content on the board, but his report will naturally focus on mathematics.

Facing the venue that had gradually quieted down, Lu Zhou tried the microphone and said concisely.

"Regarding the properties and preparation methods of modified polydimethylsiloxane films, I have made a fairly complete description in the paper, and I believe you have seen it before this report, so I will not repeat it here."

After a pause, Lu Zhou continued, "And compared to PDMS film, I believe you are more interested in how I discovered it. ”

Hearing this, many people sitting in the audience nodded one after another.

Not all of the people sitting here are researchers or corporate representatives who are interested in lithium batteries, and many of the big bulls in the field of other organic materials are also sitting here at this moment.

For people with different research directions, they are more curious not about the PDMS material itself, but about how Lu Zhou locked this material by building a mathematical model.

In response to the expectant eyes, Lu Zhou didn't waste time on the opening remarks and went straight to the point.

"In the initial stages of deposition, lithium ions typically acquire electrons and are deposited on current collectors, which is considered to be a heterogeneous nucleation behavior. Since this initial nucleation phenomenon will have a decisive impact on the final lithium deposition pattern, my initial idea is to take the early nucleation stage as the starting point to solve the problem of irregular growth of lithium dendrites. ”

"By SEM observation, the root of the crystal nucleus immersed in the electrolyte can be seen as a spherical cap-shaped crystal nucleus deposited on a flat substrate, which is a three-dimensional sphere in the abstract. We can let θ be the contact angle, r be the radius of curvature, a be the radius of the contact surface, and γ be the surface tension ......"

There are some things that can't be explained just by saying it.

Lu Zhou picked up the marker and wrote on the whiteboard.

【Sv=（π/3）（2+cosθ）（1-cosθ）²】

【∆Gt=（∆Gf+zFη/Ω）Svr³+γSAr²+（γSN-γSE）πr²sin²θ】

【……】

The more formulas are written on the whiteboard.

The tip of the pen jumps on the whiteboard, and lines of arithmetic jump out.

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

For every detail of it, he already knows every detail, even if he has not deliberately memorized it, Lu Zhou can smoothly deduce it on the spot.

The researchers sitting in the audience nailed their eyes straight to the whiteboard, for fear of missing a detail.

However, even so, there are very few people who can keep up with his pace.

Beginning to be a little unable to keep up with Lu Zhou's train of thought, Professor Krell took a deep breath and looked left and right with some anxiety.

When he noticed that Professor Bawandi from the Massachusetts Institute of Technology sitting next to him was looking at the whiteboard with his arms crossed and a relaxed expression, he couldn't help but ask in a low voice.

"Do you understand?"

Professor Bawandi did not answer this question directly.

After pondering for a moment, he gave his assessment in a relaxed tone, "Of course, it's an interesting method. ”

Professor Bawangdi is a researcher of quantum dot technology, not only in chemistry, but also in condensed matter physics.

When the field of study involves physics, it is strange that mathematics is not good.

After hearing Professor Bawandi's evaluation, Professor Krell looked helpless.

At this stage of the presentation, he has begun to understand many things on the whiteboard.

It's not that he doesn't know mathematics, it's just that he hasn't studied it so deeply. After all, materials science is an experiment-based discipline, and most of the data is made, not calculated.

However, he is now told that computational materials science is not only a support in the materials science laboratory, but also a full audience. He seemed to have no better way than to doubt life.

Perhaps, he'll have to find time to study it.

Minutes and seconds passed.

Lu Zhou, who entered the state, seemed to have returned to the Princeton classroom, and the audience in the audience were all his students, listening attentively to his teachings.

For those eyes of curiosity, Lu Zhou also responded with the greatest enthusiasm and spread his doctrine.

【τs=πD（C0EZc/2j）²（{ua+uc}/ua）……】

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

Taking two steps back, he glanced up and down at the whiteboard in front of him, but did not speak.

Staring at the back of this not tall but extremely majestic, there was silence in the audience, and there was silence, for fear that the breathing would be louder and interrupt the big guy's thinking.

And so it was, five minutes.

Lu Zhou finally turned around and put the marker pen in his hand on the multimedia podium.

"That's the basics."

"Next is the question session, if there is something you don't understand, you can ask it."

There was still silence in the venue.

No one stood up, no one raised their hands, no one even spoke.

Even the meanest experts are silent at this moment, making one wonder if this is really the scene of the MRS autumn meeting.

Gradually, the silence finally broke.

Those who came to their senses began to applaud.

"Bang Bang Bang ......"

With the first, there is the second.

Soon thunderous applause filled the room, like a storm swept through.

Looking at the applause from the audience, Lu Zhou was slightly stunned.

What surprised him was not the applause, but the fact that no one stood up to ask questions.

Thinking of this, Lu Zhou's expression couldn't help but be a little strange.

Tentatively......

Just assume they all understand.

Anyway, after the conference, the American Materials Society would print a thick collection of papers like bricks, and if they were interested, they would naturally study what he had said.

As for what he should do, he has done it.

Lu Zhou signaled to the staff next to him that the meeting was over.

However, just as he was about to unplug the USB flash drive, he suddenly remembered something.

"Oh yes, I almost forgot, the PPT hasn't finished yet."

What I just said was so hilarious that I almost forgot about "business".

Lu Zhou pressed the button on the laser pointer and quickly went through the rest of the PPT.

"There's not much to say about modified PDMS films, I've done six sets of experiments here in the past two and a half months. After 1000 to 2000 coulomb cycles, the macroscopic situation inside the battery and the SEM image of the cross-section of the anode material under the microscopic level. ”

This experiment is not difficult, but it is cumbersome and especially time-consuming.

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

The PPT was frozen on the penultimate page, and Lu Zhou, who stopped the screening, paused and continued.

"I'm sure there should be a lot of people who are more interested in this."

There are indeed quite a few people who are interested.

When I saw the picture of the inside of the dusty battery shell after the 2000 rounds of Coulomb cycle, the corporate representatives who sat in the back row and listened to the whole report meeting were staring at the PPT with their eyes almost straight.

The route to the New World was drawn on that map, and the "treasure" they had dreamed of had never been so close.

There, that's the future.

Now, someone has shown them the way......
