Scholar’s Advanced Technological System

The following afternoon, the MRS Conference Lithium Battery Thematic Reporting Room was full of people.

Many people arrived early and waited in advance for the briefing to begin.

Standing at the doorstep of the reporting room, looking at the dark pressed crowd inside, the ark could not help but have numb scalp.

Somehow, he suddenly had a little admiration for Professor Sarot, whom he met yesterday.

In a sense, it also takes some courage to come here and tear up the work of a dozen or twenty researchers in the lab, millions of dollars in research money, with imperfect projects.

In this line of work, the peers are the wrongdoers, and different lines are also the wrongdoers.

In the direction of taking lithium-sulfur batteries, those that make manganese dioxide nanospheres and polymer solid electrolytes, at first glance, seem to be things that the octopuses can't hit the edges of, but they are actually meant to solve the shuttle effect of lithium-sulfur batteries.

In fact, everyone's technology has black dots, just how many problems.

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

By the same token, the Ark's thesis, even though it brought the lithium battery concept to spring, also cut off a number of project teams, causing a number of researchers to lose their jobs for it, and I believe a number of people scolded him behind it.

But what surprised the Ark was that when he stood on the podium and swept down, he didn't see the kind of person who was obviously waiting to come looking for him.

At least he didn't see the front row.

Instead, those pairs of sights are filled with...

Expect?

The report is about to begin, although I doubt that I have read it wrong.

Settled his mind, the ark walked onto the podium, plugged the flash drive into the multimedia podium, and prompted the staff next to him to drag himself three white boards.

Normally, a material science report would not require so much content from a board book, but his report would naturally be mathematically predominant.

Faced with a venue that had gradually calmed down, the ark tried the microphone and said concisely.

“With regard to the properties and preparation methods of modified polydimethylsiloxane films, I have described them quite thoroughly in my paper, and I'm sure you've seen them before this presentation, and there's not much to go on here. ”

Pause, the ark continues, "And I'm sure you're more interested in how I found it than in the PDMS film. ”

Many people sitting under the stage nodded when they heard that.

Not all of us sitting here are researchers or business representatives with a stake in lithium batteries, and a lot of bulls who do other organic materials are sitting here right now.

For people in different research directions, they're not more curious about the PDMS material itself, but how the ark actually locks this material by building a mathematical model.

In response to those two eyes of anticipation, the ark did not waste time in the opening remarks and went straight to the point.

“During the initial phase of deposition, lithium ions typically acquire electrons and deposit them on a collector fluid, which is considered an out-of-phase nucleation behavior. Because this initial nuclear phenomenon will have a decisive impact on the final lithium deposition pattern, my initial idea was to address the problem of irregular growth of lithium branches using the early nuclear stage as the entry point. ”

“By looking at the root of the nucleus infiltrated by the SEM electrolyte, we can see a spherical cap-shaped nucleus deposited on a flat substrate, which in abstraction is a three-dimensional spherical surface. We can set θ as the contact angle, r as the radius of curvature, a as the radius of the contact surface, γ as the surface tension..."

Something just doesn't make it clear.

The ark picked up the marker pen and put the book on the whiteboard.

[Sv = (π3) (2 + cosθ) (1-cosθ) ²]

[∆ Gt = (∆ Gf + zFηΩ) Svr ³ + γSAr ² + (γSN-γSE) πr ² sin ² θ]

……

The more formulas are written on the whiteboard.

The tip jumps on the whiteboard and a row of formulas pops out.

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

For every detail of it, even if it has not been deliberately recited, the ark is very fluent in making on-site inferences.

Researchers sitting underneath the stage looked straight at the whiteboard and feared missing a detail.

But even so, few can keep pace with him.

Some thought had begun to fail to keep up with the ark, and Professor Claire took a deep breath and some anxious left looked forward to it.

When he noticed that Professor Bawandi from MIT sitting next to him was holding his arms and looking easily at the whiteboard, he couldn't help but ask in a low voice.

“Do you understand? ”

Professor Bawandi did not answer this question directly.

After a moment of reflection, he gave his own review in a relaxed tone, "Of course, it's an interesting way. ”

Professor Bawandi studied quantum dot technology, not just chemistry, but also the physical aspects of condensation.

And once physics is involved in the field of research, mathematics is bad and it's strange.

After hearing Professor Bawandi's assessment, Professor Claire was helpless.

The report will go to this stage, and a lot of things on the whiteboard, he's starting to get confused.

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

Now, however, he has been told that the position of computational materialology in the materialology lab is not only assistive, but can be used throughout Kerry's field. There seemed to be no better way for him than to doubt his life.

Maybe he'll have to take the time to study it.

Time goes by.

The ark that entered the state, as if it had returned to Princeton's classroom, and the audience under the stage, all his students, were listening to his doctrine with all their heart.

The Ark also responded with the greatest enthusiasm for that pair of eyes for knowledge, spreading its own doctrine.

[τs = πD (C0EZc2j) ² ({ua + uc} ua) …]

When the last line of formula was written, the ark stopped the pen in its hand.

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

Staring at the shadow of this not tall but unusually great shore, the silence under the stage, the crow's silence, angry fear of breathing a little louder, interrupting the big man's thinking.

Five minutes passed by.

The ark finally turned around and placed the marker pen in its hand on the multimedia podium.

“That's the basics. ”

“Next is the questioning session, if there is anything you don't understand, you can ask. ”

The venue remained silent.

Nobody stood up, nobody raised their hands, nobody even spoke.

Even the meanest experts are silent at this moment, raising doubts as to whether this is really the scene of the MRS Autumn Convention.

Gradually, silence finally broke.

Go back to the man who came to God and start applauding.

“Pfft...”

With the first, there's the second.

Soon the thunderous applause filled the venue, like the storm that swept through it.

Looking at the people clapping beneath the stage, the ark stunned slightly.

It wasn't applause that surprised him, but nobody stood up to ask questions.

I can't help but think of the strange look on the face of the ark.

Let's...

Let's just say they understand everything.

Anyway, after the meeting, the American Society of Materials printed a thick collection of brick-like papers, and if they were interested, they would naturally study what he had said in detail.

As for what he's supposed to do, he's done it.

The ship indicated to the adjacent staff that the meeting was over.

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

“Oh yeah, I almost forgot, PPT hasn't finished yet. ”

That was so high, I almost forgot about "business".

The boat pressed the button on the laser pen to quickly go over the rest of the PPT.

“There's nothing to say about a modified PDMS film, and I've done six sets of experiments here for two and a half months. After 1000 to 2000 circles of Cullen cycles respectively, the macroscopic conditions inside the battery and the SEM image of the microscopic downward negative material cross-section. ”

This experiment is not difficult, but troublesome, especially if it takes time.

However, in order to allay the concerns of industry, the experiment was necessary.

PPT was rated on the second penultimate page, stopping the show of the ark, paused, and continued.

“I believe a lot of people should be more interested in this. ”

A lot of people are interested.

When I saw the image on the inside of that dust-free battery housing after the 2000 circle of Cullen cycles, I sat in the back row and listened to the corporate delegates who were about to make the whole debrief, staring at PPT's eyes straightened.

The route to the new continent, painted on that map, is the “treasure” they've never dreamed of before.

There, that's the future.

Now, someone has given them directions…
