Chapter 272: Industry benchmark

In the afternoon of the next day, there was a crowd of people in the lecture hall on the topic of lithium battery in conference m. ． Fastest update
Many people came to the conference early, waiting in advance for the start of the report.
Standing at the entrance of the lecture hall, looking at the crowd inside, Lu Zhou could not help but feel scalp.
I don't know why, he suddenly felt a little admiration for Professor Sarote who met yesterday.
In a sense, for the rice bowls of a dozen or twenty researchers in the laboratory, for the millions or millions of research funds, holding imperfect projects and running here to tear them away with their peers, it also takes a certain amount of time. Of courage.
In this industry, peers are enemies, and different behaviors are also enemies.
In the direction of lithium-sulfur batteries, manganese dioxide nano-layers and polymer solid electrolytes may at first glance seem like things that can't be reached by eight poles, but they are actually to solve the shuttle of lithium-sulfur batteries. effect.
In fact, there are black spots in everyone's technology, just how much.
Everyone wants the industry to adopt their own solutions, invest in their own research, and let their technology "live."
By the same token, although Lu Zhou ’s dissertation ushered in the spring of the lithium battery concept, many project teams have been cut off from funding. Many researchers have lost their jobs because of this. I believe many people scolded behind it. Pass him.
But what surprised Lu Zhou was that when he stood on the podium and glanced down, he didn't see the kind of person who was obviously waiting to find the difference.
At least he didn't see the front row.
Instead, those double sights are full of ...
look forward to?
Although I suspected that I had read it wrong, the report was about to begin.
Having settled down, Lu Zhou stepped onto the podium, plugged the USB flash drive into the multimedia podium, and then signaled to the staff that he had dragged three white boards to himself.
The usual material science report will not need so much content on the blackboard, but his report will naturally be based on mathematics.
Facing the venue that was gradually quieting down, Lu Zhou tried the microphone and said concisely.
"With regard to the properties and preparation methods of the modified polydimethylsiloxane film, I have made a fairly complete description in the dissertation. I believe you have seen it before this report, so I won't go into details here."
After a pause, Lu Zhou continued, "And I believe that you are more interested in how I discovered it than the PDMS film."
After hearing this, many people sitting in the audience nodded.
Not all of the people sitting here are researchers or representatives of companies involved in lithium batteries. Many of the big names in other organic materials are sitting here at this moment.
For people with different research directions, what they are more curious about is not the pdms material itself, but how Lu Zhou locked this material by establishing a mathematical model.
In response to the pair of anticipating eyes, Lu Zhou did not waste time in the opening remarks, and went straight to the topic.
"In the initial stages of deposition, lithium ions usually acquire electrons and deposit on current collectors, which is considered a heterogeneous nucleation behavior. Because of this initial nucleation phenomenon, it will affect the final lithium deposition mode It has a decisive impact, so my initial thought was to use the initial stage of the nucleation phase as the starting point to solve the problem of irregular growth of lithium dendrites. "
"Through SEM observation, the root of the nucleus infiltrated in the electrolyte can be regarded as a spherical cap-shaped nucleus deposited on a flat substrate. Abstractly, it is a three-dimensional spherical surface. We can set θ as the contact angle, Is the radius of curvature, a is the radius of the contact surface, and γ is the surface tension ... "
Some things are simply unclear.
Lu Zhou picked up the marker and started writing on the whiteboard.
[Sv = (π / 3) (2 + osθ) (1-osθ)]
[Gt = (gf + zfη / Ω) svr + γsar + (γsn-γse) πinθ]
[……]
The more formulas are written on the whiteboard.
The nib jumps on the whiteboard, and the line of expression jumps out.
The entire mathematical model is like a carefully constructed skeleton, supporting the blood and flesh of the research results.
Every detail of it is well known, and even if it has not been memorized, Lu Zhou can perform the field derivation smoothly.
The researchers sitting under the table stared at the whiteboard, for fear of missing a detail.
Even so, very few people can keep up with him.
Already starting to think of Lu Zhou, Professor Kreer took a deep breath and looked anxiously.
When he noticed, Professor Bawangdi from the Massachusetts Institute of Technology sitting next to him was holding his arms, looking at the whiteboard with ease, and couldn't help lowering his voice.
"Do you understand?"
Professor Bavandi did not answer this question directly.
After a moment of contemplation, he gave his evaluation in a relaxed tone, "Of course, very interesting method."
Professor Bavandi is studying quantum dot technology, not just chemistry, but also involved in condensed matter physics.
And once the field of research involves physics, it is strange that mathematics is not good.
After hearing Professor Bavandi's evaluation, Professor Krel was helpless.
The report will go to this stage. He has started to understand a lot of things on the whiteboard.
He didn't understand mathematics, but he didn't study it so deeply. After all, materials science is an experiment-based discipline, and most of the data is made, not calculated.
However, some people now tell him that the position of computational materials science in the materials science laboratory is not only an auxiliary, but also Kerry. He seems to have no better way than to doubt life.
Maybe he needs to take time to study it.
Time passes minute by minute.
Entering the state of Lu Zhou, it seemed as if he had returned to Princeton's classroom, and the audience in the audience were all his students, listening attentively to his doctrine.
Regarding those pairs of knowledge-seeking eyes, Lu Zhou also responded to his greatest enthusiasm and spread his doctrine.
[Ts = πd (0ez / 2j) ({ua + u} / ua) ...]
When the last line of the formula 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, without speaking.
Staring at the back, which was not so tall but unusually powerful, there was silence under the stage, and the crow was silent, for fear that the sound of breathing would be louder, interrupting the big man's thinking.
Five minutes passed.
Lu Zhou finally turned around and put the marker in his hand on the multimedia platform.
"That's the basic situation."
"The next question is, 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 snored.
Even the most mean experts, at this moment, are still silent, making people wonder if this is really the scene of the m autumn meeting.
Gradually, the silence finally broke.
Those who returned to God began to applaud.
"Papapa ..."
With the first, there is the second.
The thunderous applause soon filled the venue, like a violent storm.
Looking at the people applauding from the audience, Lu Zhou froze slightly.
What surprised him was not applause, but that no one stood up to ask questions.
Thinking of this, Lu Zhou's expression couldn't help but be weird.
tentatively……
Just when they understand everything.
Anyway, after the meeting, the American Society of Materials will print a thick collection of brick-like essays. If they are interested, they will naturally study what he has said.
As for what he should do, he's done it.
Lu Zhou signaled to the staff at the end of the meeting.
However, when he was about to unplug the USB flash drive, he suddenly remembered something.
"Oh yes, I almost forgot, ppt is not finished yet."
What I just said is so hilarious, I almost forgot the "business".
Lu Zhou pressed the button on the laser pointer to quickly go through the rest of the ppt.
"There is nothing to say about the modified pdms film. I performed six sets of experiments here in the past two and a half months. They were after 1000 to 2000 cycles of the Coulomb cycle. Sem image. "
This experiment is not difficult, but it is troublesome, especially taking time.
But to dispel industrial concerns, this experiment is necessary.
ppt freezes on the penultimate page and stops showing Lu Zhou, pauses, and continues.
"I believe that there should be many people who are more interested in this."
Many people are indeed interested.
After seeing the picture of the inside of the dust-free battery case after the 2000 laps of the Coulomb cycle, the representatives of the companies sitting in the back row who had heard the whole report were almost staring at ppt.
The route to the New World was drawn on that picture, and the "treasure" they had dreamed of had never been so close.
There is the future.
Now, someone has indicated their course ...
