Chapter 689 An Alternative Way to Eat Bacon Sandwiches?

If lithium-sulfur batteries are nuclear fission in the field of lithium batteries, then lithium-air batteries are like nuclear fusion in the field of lithium batteries. The idea of ​​obtaining oxides from the outside air basically represents the upper limit of the energy density of all batteries using lithium metal as the anode material.

Compared with traditional lithium-ion batteries, lithium-sulfur batteries have an order of magnitude higher energy density. Compared with lithium-sulfur batteries, lithium-air batteries also have an order of magnitude higher energy density, and this is true for both volumetric energy density and mass energy density.

The only disadvantage is that it is not suitable for mobile phones or artificial satellites.

After all, the high energy density of lithium-air batteries is largely due to the fact that its oxides are not integrated inside the battery, but are located outside the battery and need to "breathe".

Cell phones are often carried in pockets, and satellites are kept out of the atmosphere, making it difficult for these devices to take advantage of lithium-air batteries. However, for new energy vehicles, or some small fixed-wing drones, there is simply no more suitable energy supply device than this thing.

It is precisely because of this that compared with lithium-sulfur batteries, lithium-air batteries have more stringent technical requirements.

Not only is the lithium dendrite problem faced by all lithium anode batteries, lithium-air batteries have extremely stringent requirements on materials on this basis. After all, lithium itself is a super active metal. To expose it to the atmosphere, it must only react with oxygen in the atmosphere. The difficulty is self-evident.

Not to mention a series of complicated side effects.

The key to solving this problem is to find a film that can filter out water vapor, carbon dioxide and other gases in the air, and accurately and quickly screen oxygen molecules.

In fact, this technology exists on Wreckage One.

The only pity is that the damage of Wreckage No. 1 is relatively large, and this film is located on the surface of Wreckage No. 1. Even if the data on the wreckage is collected with a scanning gun, there are still some difficulties in restoring this technology. difficulty.

Fortunately, with his attainments in the field of computing materials and some understanding of carbon-based materials, Lu Zhou was able to lock down a few technical routes that seemed to be more likely, and handed them over to the people of the Institute of Computing Materials for research. .

As an academic leader, he doesn't need to do every project by himself, he just needs to plan the research direction and a reliable technical route is enough.

If the technology pans out, it won't just be the battery world that will change.

From industrial production to life medicine, many fields can benefit from it...

The New Energy Vehicle Summit held in Jinling City lasted for two days, during which Lu Zhou received a lot of business cards at the meeting. Although he rarely had contact with people from the capital circles, people from the domestic capital circles were unexpectedly interested in him. .

Whether it was for the sake of the Lingyun Medal, or coveted the advantages of Xingkong Technology in the field of technology research and development, many people took the initiative to exchange business cards with him.

For those who are interested in him, no matter what purpose they have, Lu Zhou also responds in accordance with the principle of courtesy.

Although he can't use these contacts for the time being, who can tell what will happen in the future?

After all, not all projects are suitable for applying for national funding.

About a week has passed since the summit, and the time has entered the second half of October.

In this autumn season, which is suitable for sitting in the office and studying math problems, Lu Zhou unexpectedly received an email from Switzerland.

The mailbox belonged to Mr. Edward Witten.

In this email, in addition to his concern and greetings, he also highlighted the recent research progress of CERN.

Especially the part about "M Particles".

【... Regarding the "M particle" you predicted in your thesis, the relevant exploration projects have been arranged in this month's experimental plan, and if there is no accident, there will be results by the end of the month. For this experiment, we have had many meetings, and we are all looking forward to discovering some interesting things in the experiment. 】

[Finally, I wish you good health and a happy work. If there is any new news, I will let you know as soon as possible... Although I feel that CERN holds reports faster than I write letters. 】

[Also, have you ever seen a kind of tofu that looks like cheese? I'm not sure if it's a specialty of Jinling, but it's delicious in a bacon sandwich, and I recommend you try it too. Unfortunately, I have searched for a long time in the supermarket but couldn't find the same flavor... Can you send me some if it is convenient? I'll send the money over. :P]

Seeing the ":P" at the end of the email, Lu Zhou, who was drinking coffee, almost choked on the coffee.

What the hell is tofu that looks like cheese?

Maybe fermented bean curd?

After thinking for a while, Lu Zhou typed on the keyboard and replied an email.

【...I probably know what you want. 】

After clicking send, Lu Zhou closed the webpage, and was about to open the thesis just downloaded when his student Wu Shuimu happened to walk over.

"Professor, do you want to eat in the cafeteria?"

"No, I still have some documents to read... By the way, if you don't bother me, bring me back a bacon sandwich."

"Bacon sandwich? Okay." Wu Shuimu nodded and agreed.

Lu Zhou continued: "By the way, bring me another bottle of fermented bean curd."

Wu Shuimu: "...?"

In short, the professor's order must be taken to heart.

After taking a detour to the supermarket, Wu Shuimu, who finished his lunch, returned to the office with a plastic bag.

"I brought you the sandwich... and the fermented bean curd you asked for."

"thanks."

After transferring the money to Student Wu's Alipay, Lu Zhou hesitantly followed Witten's recommended eating method, put a little fermented bean curd on the bacon sandwich, and then opened his mouth to take a big bite.

Feeling the sea-like taste spreading on the tip of his tongue, Lu Zhou, who was sitting on the office chair, was silent for a while, silently covered the can of fermented bean curd, and threw it aside.

MMP!

Apart from being so salty, how delicious is this stuff? ? ?

...

Time passed day by day, and soon it was the end of October.

Just when Lu Zhou was preparing for the upcoming bidding conference for the moon landing project, and almost forgot about Mr. Witten's email, a piece of explosive news suddenly came from CERN.

In the latest round of collision experiments, CERN tested the M particle predicted by Lu Zhou in the unified theory of strong electricity, and surprisingly observed signs of the existence of this particle from the two detectors of ATLAS and CMS at the same time!

Although it is only a "sign", the confidence level has just reached 2.5sigma and 2.7sigma, and there is still a long way from "discovery", but even so, it is still quite exciting!

If this sign is confirmed as a discovery, the physics community will get a piece of the puzzle beyond the Standard Model, which is the so-called "new physics". As for the problem of the mass gap, people can finally give a clear theory to explain the reason for its existence!

Moreover, this discovery will also become a major discovery second only to the Higgs particle, and will be included in the top ten greatest physics discoveries of this century!

Even though this century has just begun...

After this news was announced, it immediately attracted great attention from the international physics community.

The Brookhaven National Laboratory of the United States quickly followed the hot spot and announced that it was preparing to repeat the experiment to test the experimental results announced by CERN. Other high-energy physics laboratories around the world also followed suit and began to prepare for the arrival of this particle.

At the same time, not only the major high-energy physics institutes were caught in the carnival, but the entire theoretical physics community was caught in a grand "carnival" because of this particle that bridges the strong interaction and electromagnetic interaction.

Various papers on this particle on Arxiv have hit a record high, and many doctors are taking advantage of the time gap before CERN has characterized it to write a graduation thesis on this thing.

Just as all physicists were looking forward to, the repeat experiment at Brookhaven National Laboratory was finally ready, and the second experiment at CERN was on schedule.

At this moment, Huaguo has not had any impact due to this news, and the electron-positron collider in Shangjing has not been able to repeat the physical experiment in the high-energy area for the time being.

However, although the domestic physics community is somewhat calm, the aerospace field is surging.

On the first Friday of November, in Harbin City in the far north of China, a bidding conference for manned moon landing was held as scheduled...
