Zhu Guangya's eyebrows, which were already very individual, couldn't help but subconsciously raised twice, and there was a trace of obvious astonishment on his face.
He originally thought that Xu Yun would provide some kind of production process for protective clothing materials, or at least some new structures that could block radiation, but what Xu Yun mentioned was actually...
Cat poop coffee?
What an outrageous development this tmd is...
Cat poop coffee.
Not an exaggeration.
In their era, probably 99% of the people in the country didn’t know what this was—including perhaps even some senior leaders.
But Zhu Guangya is not among them.
After all, he had stayed across the sea for several years and had plenty of money when he studied abroad. Of course, this has nothing to do with Zhu Guangya's family, but involves some of Zhu Guangya's background when he studied abroad.
Unlike some other big names, Zhu Guangya went to the other side of the sea not to study abroad with Geng Geng money, but to be dispatched.
In 1945, a certain bald man envied the power of the atomic bomb and proposed that logistics should have its own atomic bomb.
So he sent three big men, Wu Dayou, Zeng Zhaolian, and Hua Luogeng, to investigate across the sea, and asked each scientist to recommend two assistants to go with them.
At that time, the two assistants recommended by Wu Dayou were Li Zhengdao and Zhu Guangya.
However, after the inspection team arrived across the sea, they were told that the other party would not share any data on nuclear weapons. At the same time, due to some well-known changes in the country, the inspection team had to disband.
But the problem was that Baldhead's funds had already arrived in the investigation team's account at that time, and in order to obtain knowledge about the atomic bomb, Baldhead's funds were quite generous - after all, he had to manage some people.
Among these three commissioners.
Zeng Zhaoluan chose to return to China at that time, Hua Luogeng planned to visit the Princeton Institute of Mathematics, and Wu Dayou planned to become a professor at the University of Michigan.
So the three of them generously divided the funds into three parts and each went about their own affairs.
Then in Wu Dayou's group, Li Zhengdao chose to study at the University of Chicago after much thought.
So Wu Dayou gave him a large sum of money and a letter of recommendation, and Li Zhengdao successfully became a disciple of the big boss Fermi.
Zhu Guangya followed Wu Dayou and entered the graduate school of the University of Michigan. The graduate qualification was an advantage given to Wu Dayou by the University of Michigan.
At the beginning, Zhu Guangya actually only received some living expenses.
But a year later, Wu Dayou went to work at Columbia University. Zhu Guangya could not leave with him due to academic problems, so before he left, he left Zhu Guangya a sum of money that was more generous than Li Zhengdao...
According to Academician Zhu Guangya's recollection in 2006, that money could probably buy a quarter of the Hongkou Stadium land in Shanghai...
Therefore, Zhu Guangya was considered one of the most well-off international students at that time, if not one of them.
He can buy the books he likes at will, and often helps some classmates who have financial burdens.
Later, the reason why Zhu Guangya was able to gather 51 international students to write "An Open Letter to Students Studying in the United States" calling on overseas students to return to China to participate in the construction of the motherland was because at that time everyone did have a strong patriotic enthusiasm and had strong expectations for New China.
Hope and sojourn.
Secondly, Zhu Guangya has gained a high prestige among the international students through long-term support, so he just raised his arms and joined forces.
So in a sense.
The bald head can be regarded as having made a contribution to the scientific development of China, with tears in his eyes.JPG.
It was the relatively affluent living conditions while studying abroad that made Zhu Guangya come into contact with and fall in love with coffee.
This hobby was even retained by Zhu Guangya in China - at that time, the country had certain preferential material treatment for these international students, and Zhu Guangya chose instant coffee for all of his preferential treatment quota...
Therefore, Zhu Guangya is really no stranger to cat poop coffee.
Then he raised his head and glanced at Xu Yun. Although he was still a little confused, he still said slowly:
"Cat poop coffee...Xiao Xu, are you talking about the kind of ridiculously expensive coffee that is eaten by civet cats after ripe coffee berries are excreted from the body?"
Xu Yun nodded and confirmed his statement, then continued to ask:
"That's right, Director Zhu, do you know how this coffee bean works?"
Zhu Guangya recalled the information he learned and said:
"If the information I heard is correct... it should be that civet cats like to eat coffee cherries but cannot digest them. After fermentation in the stomach, the coffee beans will add another layer to their original appearance.
A flavor…”
Snapped!
When Xu Yun heard this, he snapped his fingers cheerfully:
"bingo!"
Cat poop coffee.
This is a kind of coffee that is very famous in later generations, but is extremely popular.
Its principle is just as Zhu Guangya said, it is produced by an animal called civet cat.
Civet cat is the big civet or Jiujiang civet in Chinese slang, with a body length of 60 to 80 centimeters. There is an aromatic gland sac under the skin of the swallow, so it is called civet cat.
Cat poop coffee, together with Thailand’s elephant poop coffee, Brazil’s bird poop coffee, and Peruvian raccoon poop coffee, are known as the four most expensive poop coffees in the world.
However, many cat poop coffees in later generations were actually faked by Robusta, and the number of real cat poop coffees is as rare as the female readers of this book...
The sight returns to reality.
Knowing that his description was correct, Zhu Guangya's face became more confused:
"Xiao Xu, forgive me for being stupid, what does the cat poop coffee you mentioned... have to do with preventing nuclear radiation?"
"Hey, don't be impatient yet."
Xu Yun waved his hand towards Zhu Guangya and said:
"You'll understand if you listen to me."
Zhu Guangya could only act like he was listening.
Xu Yun straightened his body, organized some words, and then said:
"Director Zhu, since the topic is quite complicated, let's start with the concept of nuclear radiation."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "From a conventional perspective, there are three main ways to avoid nuclear radiation."
"That means producing new types of radioactive materials for protective clothing, designing some kind of device that can block radiation - such as a cover, and developing some kind of efficient medicine."
"The first two methods and the third method in a broad sense have too long cycles and are not suitable for the current situation of the 504 factory."
"But on the other hand, if a non-generalized drug appears... there is still some possibility of reducing radiation."
"Non-general medicine?"
Zhu Guangya made a sound of doubt, but quickly reacted:
"Xiao Xu, you mean the natural ingredients that are anti-radiation?"
"That's right."
Xu Yun nodded, it was easy to talk to smart people:
"As far as I know, there are not many species in nature with natural radiation resistance, but if I had to count them, there are still a few types."
"Among these types of species, there is one type that has the most obvious effect and is the best to extract."
Zhu Guangya's breathing became faster again:
"Which category?"
Xu Yun raised a finger towards him:
"Sodium alginate."
In the future life when Xu Yun traveled through time.
Due to the bad behavior of some countries, the concept of nuclear radiation has become much more popular.
And along with this popularity, there are also all kinds of ghosts and ghosts.
For example, in many families who love each other, you can see this kind of news:
[There are more than 50 traditional Chinese medicines that can prevent nuclear radiation, so collect them quickly to protect your family’s health!]
Below this type of news, you can also see more outrageous headlines, such as there are more than 500 anti-cancer traditional Chinese medicines...
It's undeniable.
Some traditional Chinese medicines may indeed have a certain protective effect against nuclear radiation due to their ingredients, but they are far from reaching the level of miracle medicines.
Many times you may wear two extra pieces of clothing, and the effect will be better than these traditional Chinese medicines.
There is no denying that Chinese medicine is profound and profound, but if Chinese medicine is involved in everything, it would be completely flattering.
Among these soft advertisements, Houttuynia Cordata has been promoted to the altar.
For example, some marketing accounts will say "Houttuynia cordata is the only Chinese herbal medicine that can survive at the atomic bomb blast point", and "saved the lives of victims of the atomic bomb blast in Hiroshima", and "many top journals have proven that Houttuynia cordata has
When an atomic bomb explodes, the core temperature can reach tens of millions of degrees, and the temperature in the area near the explosion point can reach tens of thousands of degrees.
No living thing, including plant seeds, can survive at this temperature. Even the soil on the surface will vitrify at high temperatures, so "tenacious survival" is pure ignorance.
If plant seeds were carried by the wind after the explosion, it would be possible for vegetation to grow back at the explosion site.
But the problem is that not only Houttuynia cordata can grow in the nuclear explosion area. For example, if you search for pictures of the Chernobyl nuclear power plant, you can see that the abandoned nuclear power plant is already surrounded by lush green, as green as the top of Aslan's head in Goli.
.....
As for the article that Houttuynia cordata saved the lives of Hiroshima victims, it was from the 6th issue of "Health Vision" in 1995, titled "Houttuynia cordata - the life-saving talisman of Hiroshima people".
That's right, it was another article compiled to take advantage of the public's mentality of admiring foreign things. Later, it was misrepresented by various media that lacked discernment, leading to the spread of falsehoods.
The remaining so-called top journals... this lie is easier to shatter.
Searching "Houttuynia cordata clinical" in CNKI shows that clinical studies on Houttuynia cordata-related preparations are basically observational studies of dozens of cases.
And using the scientific name of Houttuynia cordata to search for clinical trials in the foreign database Pubmed...that is, Clinical Trial documents, there is no reliable document that is consistent with the study of drug efficacy.
So Houttuynia Cordata does not have any actual data support at least in terms of nuclear radiation, but it is quite effective in the treatment of oral mucosal inflammation.
If you have oral ulcers and you can buy Houttuynia Cordata around...that is, you can try it when you have your ears cut off. After all, some oral ulcer patches now contain hormones.
Among all natural plants currently available.
The only substance that truly has a certain degree of radiation resistance is sodium alginate, which comes from kelp or green seaweed.
It is a polysaccharide carbohydrate that is often used as a thickener and stabilizer in food, and sometimes as a preservative.
But actually.
It has a good blocking and absorption effect on lithium, radium, strontium, cobalt and other radioactive elements, especially strontium, the blocking effect can even reach 70%.
In the list of drugs for nuclear radiation emergencies updated by WHO on January 27, 2023, potassium iodide tablets rank first.
The second is chelating agents such as CaNa3 DTPA or ZnNa3 DTPA, and the third is aluminum phosphate and sodium alginate.
That is to say, in an emergency and lack of other conditions, you can try eating kelp or seaweed...
"Kelp or seaweed?"
While listening, Zhu Guangya suddenly thought of something:
"Xiao Xu, although there is no kelp in Qinghai Lake, I remember that there seems to be some kind of... Cladophora, right?"
Xu Yun grinned slightly:
"Yes, Cladophora is a standard type of green seaweed."
All the classmates who were the land lords of Xihai Province in their previous lives know this.
Although Qinghai Lake is a saltwater lake, it does not produce kelp - to be precise, basically all saltwater lakes do not produce this stuff....
On the other hand, you can see kelp, sponge seals and sharks in freshwater lakes like Lake Baikal.
But on the other hand.
Although there is no kelp in Qinghai Lake, there is a large number of Cladophora algae, even to the extent that it affects the navigation of ships.
Although this algae sounds astringent, it is actually a standard green algae that can extract sodium alginate.
This chapter is not over yet, please click on the next page to continue reading the exciting content! "Director Zhu."
Xu Yun then took a deep breath and continued:
"Although the anti-radiation effect of sodium alginate is not as good as new protective clothing and some polymer drugs, it is at least much better than Prussian blue."
"And this thing is easy to extract, because sodium alginate contains a large amount of -COO- and can exhibit polyanionic behavior in aqueous solution."
"So as long as the seaweed is crushed and extracted with strong alkaline water, the colored calcium alginate is precipitated by calcium chloride, and then reacted with sodium carbonate and dried to obtain sodium alginate powder."
"This kind of process, let alone the capital, can be completed independently even with the current level of our base."
Mentioned earlier.
The reason why Xu Yun chose sodium alginate as an anti-radiation drug is, firstly, because its anti-radiation effect is really good, and secondly, because its extraction process is very simple.
At the same time, Cladophora can be brought back by the fishing team when fishing. Even the base under current ultra-high load conditions can easily handle the entire process.
"..."
After listening to Xu Yun’s introduction.
Zhu Guangya was silent for a few seconds and then touched his chin:
"There is really no difficulty in the process. If we hurry up and arrange the time, we might be able to extract some finished products in the next two days."
"But...Xiao Xu, whether this thing is useful is another matter. What does it have to do with cat poop coffee?"
Xu Yun smiled when he heard this and explained:
"Director Zhu, do you still remember the principle of cat poop coffee I just mentioned?"
"principle?"
Zhu Guangya was stunned for two seconds:
“Is it the fermentation in the civet’s stomach?”
"That's right."
Xu Yun nodded vigorously:
"Civet stomach fermentation will destroy the protein of coffee beans and produce short peptides and more free amino acids, thereby changing the flavor of coffee beans."
"For the same reason, according to some papers I learned... ahem, the experimental report shows that if Cladophora is processed through a similar process, the effect of sodium alginate on nuclides can also be enhanced by increasing free radicals.
Barrier."
"oh?"
Zhu Guangya suddenly raised his brows, but soon showed a hint of embarrassment:
"But there are not many cats in the base, let alone civets - it is impossible to let Comrade Yuan Guoliang's Huahua bear the burden of this huge project, right? He is still a child."
Xu Yunze quickly shook his head:
"Director Zhu, you misunderstood what I meant."
"I just said that the process is similar to the principle of cat poop coffee, but I didn't say that civet cats are needed."
"The animal that can handle Cladophora is not a cat, but..."
