Chapter 184 A Gold Mine

Shangjing, in an apartment building near Mizuki University.

An old man was holding an English magazine in his hand and was reading it while sitting on the sofa.

Halfway through, he suddenly smiled, put down the magazine in his hand, and said, "This kid is quite talented."

This old man wearing glasses is none other than Mr. Qiu Chengtong, the world's leading figure in Chinese mathematics circles, Mr. Qiu.

And the magazine he held in his hand was nothing but the English version of Nature Weekly. And on the page that was opened, it was the British female reporter Belinda's interview with the intern named Lu Zhou.

In the interview, the magazine mentioned the interviewee's identity as a master's student at Jinling University, and also mentioned that he was a member of the LHCb Huaguo Cooperation Group, and his views on the signals appearing in the 750GeV energy region.

As Academician Gao, the head of the Huaguo Cooperation Group of the LHCb project, said before, this intern helped the Huaguo Cooperation Group, which had no sense of existence at first, to win on the international stage of CERN.

I believe that it won't be long before there will be overwhelming reports on this young scholar who appeared in "Nature Weekly" in China.

And these honors are all due to him.

"yes."

The old man sitting opposite Mr. Qiu sighed softly while drinking tea.

This is none other than Academician Wang Xiping, who Lu Zhou met once in Princeton.

Although the relationship between old Mr. Qiu and Yan University is very bad, to the point where they bombarded each other in the media and turned against each other, but the old man still has a few good friends in Yan University.

Academician Wang Xiping, for example, is one of them.

After pausing for a moment, Mr. Wang continued to sigh with emotion: "After the academic conference in Princeton, I thought that this kid's skills were all in number theory, but I didn't expect him to have such a high talent in the field of high-energy physics. Young and promising I have seen quite a few scholars of this kind, but I have not seen a few of this kind of all-rounder.”

Qiu Chengtong smiled and said, "I have seen one."

"Who?"

"Terence Tao!"

Wang Xiping was slightly taken aback, then smiled and said, "Do you think so highly of him?"

Tao Terence, the first Australian to win the Fields Medal, and the second Chinese to win this honor after Qiu Chengtong in 1982, is now teaching at UCLA. He is a recognized genius in mathematics and is amazing all-rounder.

Although he did not involve in the research in the field of physics, his research scope covers almost all fields of mathematics, from harmonic analysis to nonlinear partial differential equations, and even his research has spread from the field of pure numbers to the field of corresponding numbers , such as the principle of compressed sensing in cameras has his research results.

Many people evaluate him as Mozart in the mathematics world, because apart from being a genius, there is no suitable reason to explain why so many achievements will appear in a mortal.

Although many people in the domestic mathematics circles have commented on this Lu Zhou, calling him "little Tao Zhexuan", they still use the word "little" after all. In Wang Xiping's opinion, the old friend's evaluation is still too exaggerated.

Mr. Qiu smiled and said, "Is the evaluation high? I even think that he has every hope of surpassing his predecessors!"

Hearing that this old friend had such a high opinion of that young man, Wang Xiping was secretly surprised, and couldn't help asking: "Are you serious?"

"Of course," old Mr. Qiu nodded, "When I saw that he chose the Polignac conjecture as a research topic, I actually had this premonition at the time. Now that I read this report, But it made me even more certain about it.”

Wang Xiping asked with a smile: "Do you think he can solve this problem?"

"It's hard to say, he even solved the twin prime number conjecture. If it wasn't for lack of energy, and number theory is outside the scope of my research, I would like to try to challenge this difficult problem," Mr. Qiu sighed with emotion, and suddenly his eyes Turning around, he looked at his old friend and said with a smile, "Why don't we make a bet?"

Wang Xiping asked with a smile, "What are you betting on?"

"I bet he can solve this conjecture within two years."

"Unrealistic." Wang Xiping shook his head, "I know you think highly of him, but his current research direction is not number theory, but mathematical physics. If he concentrates on number theory, it is possible to complete this project... ...But looking at it now, two years is still too short!"

Old Mr. Qiu shook his head: "The direction of research is not a problem, interest is the best teacher. In my opinion, he has the talent to complete this work. Since we have opposite opinions, should we take a gamble?"

Wang Xiping patted his thigh and said with a smile, "Okay, let's gamble! I'll offer one hundred yuan, and I won't lose if I lose anyway."

Old Mr. Qiu scolded with a smile: "You old bastard, you think about losing before you start gambling. I won't bet with you anymore, it's boring!"

...

"Ah Choo!"

After sneezing, Lu Zhou rubbed his nose, muttered "Who is scolding me", and continued writing at his desk.

He has already read Academician Lu's class schedule.

But it's still in the summer vacation, and the latest class will be next month, so don't worry about it for now.

These days, Lu Zhou seldom went out of the dormitory door, and kept himself locked in the dormitory, facing the data in the computer, racking his brains to design experiments.

In order to design the PDMS film, he had to consult a large amount of literature, and based on this, he conceived an experimental idea.

The reason why he is so focused is, of course, the issue of money.

Guarding a large piece of gold mine, if he doesn't get something down from it, he really can't even sleep well.

As for using a gold mine to describe this technology, it is not an exaggeration at all, and even underestimated its value.

As early as 20 years ago, lithium metal as a negative electrode was abandoned by the industry. Because of the short-circuit problem caused by dendrite growth, the battery became an incendiary/incendiary bomb, which "blew up" a listed company with a market value of tens of billions.

However, the strong market prospect of lithium metal still attracts countless material science laboratories to pour in on this topic one after another.

At the enterprise level, IBM has even prepared a supercomputer for the lithium-air battery project, which distributes and calculates the path of each gas molecule entering the battery cell to avoid the problem of gas clogging... Although it was later discovered that it was a bottomless pit, the capitalists did not care about it. Mercifully cut it off.

At the national level, for example, the Minister of Energy in the Obama team, Mr. Steven Chu, a Chinese-American who won the Nobel Prize in Physics in 1997, was a fanatical supporter of lithium negative batteries for a while... Although in the end it was rejected by a group of people persuaded.

As for why lithium batteries have such fascinating magic, we have to mention the concept of energy density.

The so-called energy density is the energy contained in a unit volume. As the most important indicator to measure the performance of a battery, improving energy density has always been the pursuit of the industry.

Even in the 13th Five-Year Plan of Huaguo, it is clearly planned that by 2020, the technical level of power batteries will be synchronized with the international level, and the production capacity will maintain the world's leading scale. The core red line is to increase the energy density of the power battery to 300-350Wh/kg.

At present, the lithium-sulfur battery that is still in the laboratory is most likely to win the top spot.

But if the problem of lithium dendrites is solved, those hot concepts will all have to be sidelined to make way for lithium negative batteries.

Anyone who has studied chemistry knows that first of all, a lithium metal negative electrode has the lowest electrochemical potential -3.04V, not to mention a specific capacity as high as 3,861mAh/g.

Using lithium material as the negative electrode, the energy storage effect can even reach ten times that of graphite batteries in theory, and the energy density of graphite negative electrode materials can be crushed in all directions!

And the most attractive thing is that once the problem of lithium dendrite growth is solved, it does not even need to make major design changes to the existing battery, even if the existing common graphite anode material is directly replaced, the battery energy can be achieved. A leap in density!
