Chapter 692 Nobel Prize
At 7 o'clock news in the evening.
Across the country, I don't know how many families are watching the 7 o'clock news.
Starting from 7 o'clock, all CCTV channels, satellite channels, city TV stations, and county TV stations are unified as CCTV 7 o'clock news.
Even businessmen will choose to watch the 7 o'clock news at this time, because it is of great value, and can discover potential business opportunities, predict risks in advance, and discover policy dividends.
For people in the system, it is even more important to watch the 7 o'clock news, because it is closely related to their own career.
When the time displayed on TV was approaching 7:30, everyone thought that the two 7 o'clock news hosts would say the common farewell words and start to turn to advertising time, and then people would wait for the weather forecast.
As a result, a shocking scene appeared next, and even the news host was surprised.
"Here is a temporary news."
"Just today, about 10 minutes ago, the Royal Swedish Academy of Sciences announced the list of this year's Nobel Prize in Physics"
When he said this, the host paused for a second.
In this second, he adjusted his mentality and showed his extremely high hosting skills.
He continued to report in a steady voice: "Because of his 'discovery of new superconducting materials' and his outstanding contribution to the development of superconducting materials in the world, Comrade Liu Tao, who graduated from Beijing University of Technology, is currently the general manager of Panshan Group and the secretary of the Party Group, and a senior party official of Southwest Associated University, will be the only winner and will receive 10 million Swedish kronor, about 1 million US dollars."
"At the same time, he will also become the first Chinese scientist to win the Nobel Prize in Science for scientific research conducted in China, which is the highest award won by the Chinese physics community so far."
"Nobel Prize."
Including the introduction of the Nobel Prize, and the introduction of Yang Zhenning, Li Zhengdao, and Ding Zhaozhong who won the Nobel Prize before, the introduction of Liu Tao's identity and the honors Liu Tao received, the report lasted for ten minutes.
With the broadcast of the seven o'clock news, the news that Liu Tao won this year's Nobel Prize in Physics spread at an incredible speed.
The whole of China was boiling because of this news.
The last time Liu Tao appeared on the 7 o'clock news was when he won the "Turing Award". It was also that large-scale publicity that made the "Turing Award" the second most well-known international award in China.
At the same time, Liu Tao's family was watching the 7 o'clock news in front of the TV.
When they saw the official news report that Liu Tao won the Nobel Prize in Physics, everyone was excited.
Even Zhu Lin, who knew about it before, was also very excited when he saw the news.
This is the Nobel Prize, the most well-known international award in China.
Liu Tao had a faint smile on his face.
Excited?
That's for sure.
As the highest honor in the academic world, if someone says that he is not interested in the Nobel Prize, he is either pretending, or he is saying that the grapes are sour because he can't eat them, or he won the Nobel Peace Prize.
But if you say that you are too excited, that's not the case.
For any Chinese scientist with a sense of family and country, I am afraid that this Nobel Prize is probably not as good as the highest national awards such as the National Highest Science and Technology Award.
Just like Qian Xuesen, he described the most exciting moments of his life as the time when he was integrated with the country.
Science has no borders, but scientists have nationalities!
Of course, he can also guess the game behind his winning of the Nobel Prize in Physics this time.
China needs this Nobel Prize because it can inspire national confidence and also means that China's scientific research level is in line with the international level.
Sometimes Liu Tao can't understand why the citizens of a country with its own industrial system and "two bombs and one satellite" have no self-confidence. This is simply incredible.
Of course, Liu Tao was a little surprised that the jury awarded him the Nobel Prize for "discovering new superconducting materials" as a contribution.
To be honest, in his publicly published papers, "discovering new superconducting materials" is not the most important achievement, and this achievement was published by him in 1981.
This achievement is of course also a Nobel Prize-level achievement.
The biggest problem with superconducting applications is how to increase the critical temperature for entering the superconducting state. If it has to be cooled to the temperature of liquid helium, the cost will be too high. However, since the discovery of superconductivity, after 70 years of efforts, the superconducting transition temperature has increased by less than 20K. At that time, Liu Tao took a different approach. Instead of exploring traditional superconductors, he found high-temperature superconductors from metal oxide ceramics. He found that the La-Ba-Cu-0 system had superconductivity with a critical temperature of up to 35K.
After Liu Tao published his paper, many countries followed suit and competed to manufacture and test various samples, setting off a superconducting research boom. In less than three months, the transition temperature of superconductors was raised to the liquid nitrogen temperature range (replacing liquid helium with liquid nitrogen can reduce the refrigeration cost to a few tenths to one percent), and the temperature at which the transition started was raised to more than 100K.
This has made a great contribution to the development of superconducting materials.
However, there are many other achievements that are comparable to this, and some are even more important than this.
He just smiled at this.
Relativity is Einstein's greatest achievement, which is relativity and quantum theory. However, he was awarded the Nobel Prize for his contribution to modern physics, especially for his elucidation of the law of photoelectric effect.
Just two days later, another surprise came.
Liu Tao, John B. Goodenough and Stanley Whittingham won the Nobel Prize in Chemistry this year, but it was in recognition of their research contributions to lithium-ion batteries.
The advent of lithium-ion batteries can be said to be a major invention that has left a strong mark in human history.
The technology of using lithium in batteries was proposed by Whittingham, a technician at the American Oil Company at the time, in 1976. At that time, the structure was that titanium disulfide was used as the positive electrode material and lithium was used as the negative electrode material. However, the battery composed of titanium disulfide and lithium could not work stably as a secondary battery. Therefore, lithium batteries are used as non-rechargeable primary batteries such as fishing float batteries and flash power sources for disposable cameras.
In 1980, Goodenough, who was studying lithium batteries, proposed using lithium cobalt oxide as the positive electrode material. In the same year, Liu Tao published a paper proposing a combination of lithium cobalt oxide positive electrode and carbon-based material negative electrode.
Lithium-ion power plants developed rapidly under the promotion of Liu Tao. In recent years, lithium-ion batteries used in personal devices such as mobile phones and laptops have been put on the market.
The reason for using lithium-ion batteries is that the required voltage has dropped due to the miniaturization of the device body. The original 5.5V is now only 3V. Therefore, compared with the use of three nickel-cadmium batteries that can only output 1.25V, the use of lithium-ion batteries that can output more than 3V is more efficient.
Now, lithium-ion batteries are more and more widely used and more and more popular in the market.
This time, the Nobel Prize in Chemistry was awarded to three of them, and the three of them represented China, the United States, and the United Kingdom. It can be said that the face of the three countries was taken care of.
This also means that Liu Tao set a record. He became the first person since the establishment of the Nobel Prize to win two Nobel Prizes at the same Nobel Prize.
