The Science Fiction World of Xueba

December 10, 2021.

Three o'clock in the afternoon local time in Stockholm.

It's that time of year again for the Nobel Prizes.

It's the cold winter, with heavy snowfall and high latitude, the sky in Stockholm gradually gets dark at three o'clock in the afternoon.

But the whole city was in a scorching atmosphere like burning oil.

Especially the Stockholm Concert Hall in the city center is crowded with people.

The nearby streets have already been cordoned off, and both sides of the road are crowded with Stockholm citizens and tourists from various countries waving national flags.

Among them, the most eye-catching ones are the Chinese and overseas Chinese waving the five-star red flag.

Two Chinese people won the award this year, which has aroused great repercussions among overseas Chinese.

Pang Xuelin's achievements have also been spread all over the world through major media around the world.

Especially after the success of the Golden Dragon battery project, the case of detaining Qi Xin in the United States pushed Pang Xuelin's reputation to its peak.

Some media even conducted a survey on Pang Xuelin's global popularity. In the United States, 75% of people have heard of Pang Xuelin's name; in Japan and South Korea, more than 80%; in Europe, more than 70% of people know Pang Xuelin's name. %.

Coupled with the fact that Pang Xuelin won the Nobel Prize at the age of 24, in a sense, Pang Xuelin has become one of the most famous scientists in the world.

Sitting in the car, Pang Xuelin looked at the cheering Chinese people who were waving the five-star red flag along the way, and there was also a warm current in his heart.

Although in his own opinion, being recognized by the Nobel Prize is nothing, after all, there is a system around him, and he will even have the ability to weaken the authority of the Nobel Prize in the future.

But for the Chinese who have the Nobel Prize plot, this is a moment of national celebration.

The convoy stopped in front of the famous Stockholm Concert Hall. The concert hall is simple and simple, with ten giant pillars extending from the ground to the eaves. The statue of Orpheus is located in front of the concert hall.

Pang Xuelin got out of the car, accompanied by Zuo Yiqiu and the staff of the organizer, and walked into the Stockholm Concert Hall.

However, these winners did not directly enter the lobby of the concert hall, but waited in the background.

Every winner is followed by the organizer's staff, telling them the general process of the award ceremony.

In addition, Pang Xuelin was accompanied by a well-dressed Swedish female college student. He only needed to follow this female college student from behind the scenes to the stage to accept the award from the King of Sweden.

At four o'clock in the afternoon, solemn music sounded.

The first to appear is this year's Nobel Prize winners in literature, followed by physics prizes, chemistry prizes, medicine or physiology prizes, and economics prizes.

As for the winner of the Peace Prize, it was awarded by the Norwegian Nobel Peace Prize Committee and has nothing to do with Sweden.

It wasn't until half an hour later that the staff beside Pang Xuelin whispered in Pang Xuelin's ear: "Professor Pang, it's your turn."

Pang Xuelin nodded with a smile, and followed the Swedish female college students leading the way into the main venue of the concert hall.

The layout style of the main venue is mainly solemn and elegant, and there is a bronze bust of Nobel under the white curtain in the middle of the stage.

Ten flower baskets were placed on the stage, in which gladiolus and lilies were placed.

In the sound of music, Pang Xuelin stepped into the center of the awarding platform.

The speech of Lars Hecktens, chairman of the Nobel Foundation, sounded in my ears: "Since the invention of the voltaic battery in 1800, over two hundred years, from lead-acid batteries, to lithium batteries, to fuel-air batteries, We have always been committed to improving the energy storage density of batteries. Especially in recent years, with the increasing scarcity of chemical resources such as petroleum and coal, and the increasing environmental pollution, the development of new green energy has become a top priority for the development of human society.

Li-air batteries are known for their high energy density and long cycle life. The advantages of being green and pollution-free have become the focus of global scientists. And the one who has made a major breakthrough in this field is Mr. Pang Xuelin from China. He is one of the youngest Nobel laureates in history. His achievements, from mathematics to materials science, to electrochemistry, have pointed out the direction for the development of human society. His achievements in the field of graphene and lithium-air batteries lead us from the oil age to a more environmentally friendly and green future. Professor Pang Xuelin, the winner of this year's Nobel Prize in Chemistry, is invited! "

After Lars Hecktens' words fell, there was a burst of warm applause at the scene.

Pang Xuelin slowly walked onto the stage and came to the Swedish King Gustav.

"Hello, Your Majesty the King."

Pang Xuelin bowed slightly and smiled.

Gustav smiled and said: "Professor Pang, hello. You are the youngest winner I have ever seen. I hope to see you again on this stage in the future."

"Your Majesty thinks I can win another prize?"

Pang Xuelin showed surprise on his face.

Gustav smiled and said, "Why not? Young man, I have read your information. You are the most talented and incredible scholar I have ever seen. It is a pity that there is no Nobel Prize in Mathematics, otherwise you should have won it long ago." Award. Of course, we also have prizes in physics and physiology, and I look forward to meeting you here again."

"Thanks!"

Pang Xuelin received the gold medal and certificate from Gustav. Both sides smiled and shook hands, and then took a group photo with reporters.

The award ceremony lasted until 5:30 in the afternoon, and then Pang Xuelin followed other winners to the Stockholm City Hall to attend the Nobel Prize dinner.

There were more than 1,300 guests attending the dinner, and the organizer thoughtfully arranged Pang Xuelin's parents, grandparents, Qi Xin, Yao Bingxia, and Zuo Yiqiu at the same table.

Before the official start of the dinner, the ten winners need to speak on stage one after another.

At 6:15 p.m., Pang Xuelin walked slowly onto the podium amidst warm applause.

"Dear Sir, Honorable Laureates, Ladies and Gentlemen:

It is a great honor for me to meet you here today.

Before I report, I would first like to thank the Nobel Prize jury and the Nobel Prize Foundation for awarding me the 2021 Nobel Prize in Chemistry. This is not only an honor for me personally, but also a reward and encouragement for my scientific research team.

Regarding the research and development process of lithium-air batteries, you may have seen it in many reports. Here, I only give a brief introduction.

In 2020, when I made a report tour in the United States, I met Professor Kirton Walker in Princeton.

At that time, Professor Kirton Walker was in a difficult situation, but I was very moved by his dedication and pursuit of lithium-air batteries.

Because of this, I agreed to cooperate with Professor Kirton Walker to set up an experimental team at Jiangda University to find a successful path.

In this team, besides Professor Kirton Walker and me, there are also Professor Ye Xingmin, Professor Huo Ziqian, Professor He Wenyan, Professor Qiu Qiwei, Professor Xu Ting and many colleagues who have worked hard for this project.

I am proud of them, because of their unremitting efforts, we were able to complete the breakthrough of lithium-air batteries in such a short period of time.

Lithium-air battery, more accurately called lithium-oxygen battery (Li-O2), is a battery that converts electrical energy based on the chemical energy of metal and air.

The theoretical energy storage density of this battery is so high that it has been considered the ultimate energy source in the battery industry.

But in the eyes of many knowledgeable people, lithium-air batteries have many insurmountable obstacles.

Like how to prevent chronic leakage of a diaphragm using two electrolytes?

How to increase the usable temperature of organic electrolyte?

How to find catalysts that can replace the gold and platinum currently used?

How to prevent explosion caused by moisture intrusion when replacing lithium fuel?

How to recycle unused lithium and lithium hydroxide?

How to reduce the energy consumption of circulating lithium hydroxide and so on.

So many pitfalls that when I announced the development of lithium-air batteries, many people thought the project was purely a gimmick. "

Pang Xuelin paused, and there was a burst of laughter at the scene.

After all, because of the lithium-air battery project, the bet between Pang Xuelin and others has already spread all over the world.

Everyone understood what he meant.

Pang Xuelin smiled and continued: "But in the end, I proved that this is not a gimmick. Because of this personal experience, I hope that the academic world can be based on a more relaxed atmosphere for some of our young scientists.

Really interesting scientific research is driven by curiosity, and sometimes produces new breakthroughs in areas that people did not expect.

Even if some discoveries can't really solve the problem, they can let us know more about the universe, nature, society and ourselves.

Just like Dr. Wilson, who is known as the king of accelerators, when he and his mentor Lawrence developed the cyclotron in the 1930s, no one knew what this thing could bring us.

But in the end, his accelerator became an important part of Fermilab in the United States, not only played a vital role in the research of nuclear bombs, but also in the later physics research, almost all the progress in the field of basic physics came from advances in accelerator technology.

At the same time, as a young scientist, I would like to give some advice to academia.

The quality of future scientific research depends on the efforts of our young scientists. We need higher-quality talents, so that young scientists can devote themselves to the academic environment of research without any worries, so that young students can become interested in scientific research and be willing to become As a scientist, I hope that academic research is not only rigorous and scientific, but also interesting and imaginative. I also hope that some achievements of Nobel laureates can arouse some interest of young scientists and inspire them to invest more time and energy in the field of science.

Here, I would like to thank all the domestic and foreign colleagues, peers and friends who have contributed to the research and development of lithium-air batteries!

I am deeply grateful to my family for their understanding and support!

Sincerely thank you for coming to the meeting!

thank you all! "
