Of course, there is a chalkboard.

Even if he didn't, someone would drag him in if he needed it.

After hearing Lu Zhou's request, Lu Lao immediately ordered the secretary who was sitting next to him.

In less than two minutes, the conference staff dragged a movable blackboard standing on a shelf from the lecture hall next to the auditorium and placed it in front of the auditorium.

Walking to the blackboard, Lu Zhou picked up the chalk, and after thinking for a while, he began to write on the upper panel.

A similar study he had already done at Princeton when he was working on the topological transformation problem of a sphere.

In particular, he has systematically analyzed the relationship between the electrochemical and mechanical properties and structure of hollow carbon balls, and established mathematical models in a targeted manner.

At present, it is just a selection of some of the results from the research that has been done and generalized.

With Lu Zhou's level of mathematics, this is not a difficult thing to do.

The meeting seemed to enter an intermission and fell silent.

Everyone was silent, watching him write.

Professor Sun was stunned and watched Lu Zhou write on the blackboard, obviously not expecting that this guy could really write with a pen.

In fact, if he had studied mathematics, or even had some understanding of the mathematical community, he would not have the idea that Lu Zhou could not prove such naïve.

After all, the one who stood in front of the blackboard to write the process of writing the book had left a legendary cow in Princeton because of the live proof of the twin prime conjecture.

In contrast, it is not difficult to generalize a theory that has already been completed.

It wasn't until he wrote the last line of the equation that Lu Zhou stopped the chalk in his hand and looked back at the other professors in the conference room.

"According to my calculations, hollow carbon nanospheres with a specific surface area in the range of [2326m2g-1, 3762m2g-1] and a diameter in the range of [60nm-70nm] can theoretically effectively slow down the diffusion of polysulfide compounds, thereby inhibiting the shuttle effect."

Of course, this is only a theoretical feasibility. More specific product formulas, molecular morphologies, and more conclusions need to be verified experimentally, and only the possibilities are demonstrated here. ”

"That's the basics, are there any questions?"

This one......

It has to be gone.

The professors and scholars present stared at the equations on the blackboard with serious faces, but they were confused in their hearts. The engineers from the company are frantically taking notes, whether it is useful or not, whether they can understand it or not, in short, they will write it down first.

Lu Lao's eyes lit up, although he couldn't understand it even more, but he saw the dawn of new energy.

Sighing in his heart, sure enough, Lu Zhou put down the chalk in his hand.

At the MRS meeting, no one could understand his mathematical proof, and a group of lithium battery material bulls could only look at his conclusions and nod, and none of them came out to ask questions.

Here, too.

……

In fact, when studying "Wreckage No. 1", Lu Zhou has been thinking about a problem.

It's not about the technology itself, it's about something outside of it.

Objectively speaking, the birth of a technology must conform to a certain objective law.

Taking the zipper that can be seen everywhere as an example, human civilization invented clothes in order to cover the body, and in order to make clothes more convenient to wear, buttons were gradually invented in social production activities. Soon in the 19th century, the Industrial Revolution led to a leap in productivity and production technology, and then the birth of the zipper.

For the same reason, Lu Zhou believes that the advanced civilization that has mastered lithium-air battery technology has definitely not mastered this technology from the beginning.

In the history of their civilization, there must have been something similar to pre-technology.

All things considered, the possibility of lithium-sulfur batteries is high.

Although the carbon nanospheres in the anode material of the wreckage No. 1 are not directly related to lithium-sulfur batteries, they are instructive in a sense.

No technology can be achieved overnight, and similar hollow carbon ball technology must have been developed elsewhere before it can be applied to lithium-air batteries.

Considering the hint of the system task, intuition told Lu Zhou that those hollow carbon balls might become the key to solving the technical bottleneck of lithium-sulfur batteries.

So, at the seminar, he made this immature point.

As for whether it can be convincing, it's not his business.

After the seminar, the attendees left the venue.

Professor Wang, who was sitting in his seat and had not moved, had a somewhat unhappy expression.

Although it stands to reason that he has no reason to be unhappy, after all, he is engaged in carbon-sulfur composite materials, and hollow carbon balls are also a kind of carbon-sulfur composite materials, but Lu Zhou's attitude towards him made him very dissatisfied.

In his research team, the 23-year-old researcher also does the job of serving tea and pouring water, and in turn educates himself?

Not only that, he thought that Lu Lao attached too much importance to this young man.

Although scientific research is profound, it is really unskillful. The method is nothing more than continuous experimentation, continuous trial and error, summing up experience from mistakes, and then using experience to pile up new theories.

From this point of view, experimenting is like gambling.

Many people have tried the idea of adding surface polymer materials to the surface of the lithium anode, and Moli Company smashed hundreds of millions of dollars into it, and after bankruptcy, it was taken over by Nippon Electric Power, and then smashed hundreds of millions of dollars into it, but there was still no result.

You come over to a math person, write a few lines of formulas and calculate an ambiguous result, and do a few experiments to solve a project that needs to cost hundreds of millions or even billions, this luck is too good, right?

If you want to talk about psychological balance, then Wang Haifeng must be unbalanced.

However, I have to admit that this line of work is so realistic.

Before that, computational materials science was only an unpopular subject, and most of them went to the research direction of software development after most master's degrees, but after the paper published in Nature last year, many universities are now considering whether to add a functional analysis course to the general course of the Institute of Chemistry, or put it in the elective course.

Glancing at the direction of Lu Zhou, Wang Haifeng finally couldn't help it, and complained to Academician Wu Shigang next to him.

"Isn't this kid crazy?"

Although there are differences in academic opinions, everyone is engaged in lithium-sulfur batteries, and the relationship between everyone in private is still good. As for this Lu Zhou, it was a character who suddenly appeared, and there was no such person in the domestic materials science community before.

However, Academician Wu and Wang Haifeng have different views.

Engineer-born scholars are mostly pragmatic, and in his view, age, status, and family are all secondary, and although he has reservations about Lu Zhou's academic views, this view is only academic.

Moreover, he has always spoken relatively straight, and what to say.

This is true at meetings, and it is true on weekdays.

Wu Shigang glanced at Wang Haifeng and retorted: "He spends his own money to do research, and you still care about others?" Let's just do our own research. ”

After speaking, Mr. Wu packed up his things and left.

Wang Haifeng, who was choked by Lu Zhou's words before, was choked by a sentence from an old friend with a stomach full of complaints, and he couldn't help but increase his blood pressure, and his face was red.

It was a long moment before he muttered something out of his mouth.

"What are you proud of? dragged it like 2580,000. ”

With that, he picked up his thermos and walked away.
