Chapter 43 The fourth generation that must be broken through
In a claustrophobic space.
Looking at the three objects in front of him, Xu Yun's expression was a little subtle.
Putting aside the easter eggs for now, it is easy to see from the description that this should be something that needs to be triggered in combination with certain real-life situations. There are currently no clues to judge.
Even in Xu Yun's view, considering his 80% critical hit rate not long ago, when Barbarian hit 5 times with 0 critical hits, it is not certain whether he will have the opportunity to activate the easter egg in this life...
Everyone understands the pain of African chiefs.
After putting the Easter eggs aside for the time being, there were only two things left.
The first is Mavericks’ thinking experience card.
How do you say this thing...
There is no doubt that it is a good thing!
As the founder of modern physics, Maverick's intelligence is undoubtedly a peak in human history. To be conservative, he is definitely in the top ten.
Especially the Mavericks who were 22 years old in 1665. Probably no one in history can compete with him.
Therefore, there is no doubt about the quality of this thinking card. The only thing to worry about is its usage time.
Half an hour is enough for Brother Dong to fight 15 times. However, in terms of solving problems, half an hour can only do a lot, but it can’t be said to be a lot.
Especially when facing some difficult problems, two or three hours is often the norm. Even in some mathematics forums, it takes four or five hours to solve a problem as a basic exercise.
Therefore, once this thinking card is used, it must be used on the blade, and timing is the most critical.
Xu Yun then moved his eyes to the piece of kraft paper, which was the reward recording the so-called fifth-generation imidacloprid formula.
Considering that there were no desks and pens in the space, it was not suitable for research and calculations, so Xu Yun thought for a while and silently said "Return" in his heart.
Swish——
The space disappeared in an instant, and his consciousness returned to his hut.
After regaining consciousness, Xu Yun did not rush to summon the imidacloprid formula. Instead, he lowered his head and read...
own feet.
At this moment, his feet were bare, without shoes or socks.
That's right.
Neither the original Anta shoes nor the brogues given to me by Mavericks came back with me.
Seeing this, Xu Yun couldn't help but touched his chin:
"In other words, the things on my body that meet the conditions will travel with me to the dungeon, but the things in the dungeon cannot be brought back?"
Then he thought of something and looked at his ankle again:
When he went to William's house for the first time, Mavericks took him to chop firewood once. At that time, Xu Yun's left ankle joint developed a red and swollen mass, which did not subside in the following days.
Instead, a piece of broken skin formed.
But at this moment, the skin of Xu Yun's left ankle was smooth, with no trace of any break or squeeze.
In addition, in the past two weeks or so, due to the problems of living standards in the 17th century, Xu Yun's body was more or less smelly, and his clothes were not very clean.
But at this moment, these smells have long disappeared.
Xu Yun looked at the alarm clock on the table again. Four twenty-seven in the afternoon was exactly the same as when he entered the space.
"That is to say..."
"My soul traveled to the seventeenth century, but the things I carried with me when I traveled will selectively appear in the dungeon?"
"For example, glasses, clothes and shoes are modern in style, but the technology that already existed in that period will travel with me, and mobile phones, headphones, etc. will be automatically blocked?"
Xu Yun touched his chin thoughtfully. With such a comparison, the mapping relationship between the copy and reality became much clearer.
It's a pity that I didn't think enough about it before and didn't try to get a haircut at Maverick's house to see if my hair style would change after I came back.
Then he came to the desk, stretched out his hand, and concentrated his attention on sensing.
call out--
The next second, a piece of brown paper gently fell into his hand.
There are a bunch of dense chemical symbols and Chinese characters written on the kraft paper, and some of the chemical structures make people feel dizzy at a glance.
However, as a PhD student in biology who was about to receive his degree, Xu Yun could easily see the beginning of the chemical structure.
C9H10ClN5O2, which is 1-(6-chloropyridin-3-ylmethyl)-N-nitroimidazolidin-2-ylamine, scientific name...
Imidacloprid.
It is a nitromethylene systemic insecticide, a chlorinated nicotinyl insecticide, also known as a neonicotinoid insecticide. It was formally proposed at the 1991 Brighton Crop Protection Conference in the UK.
superior.
It is an agent of nicotinic acetylcholine receptors, which interferes with the motor nervous system of pests and causes the failure of chemical signal transmission. It is mainly used to control piercing-sucking mouthpart pests and their resistant strains.
In agriculture, it is mainly used for the control of aphids and plant lice, but its biggest use in life is to kill various furniture pests.
Since its launch in 1991, it has been rapidly promoted and has spread to more than 40 countries around the world in just three years.
Today, it can be said that if there is a plant protection department, there is imidacloprid. Currently, imidacloprid has become the world's number one insecticide, and its global sales in 2014 have reached 1.14 billion US dollars.
However, for such a product that has come to the forefront, life has not been easy in recent years.
The first is the problem of pest resistance caused by long-term use. With the widespread use of imidacloprid, a large number of greenhouse pests have become resistant to imidacloprid - just like antibiotics, it is an inevitable result of widespread use.
Secondly, because the target of imidacloprid is nAchR, it has a defect that it will be seriously ineffective after multiple rounds of delivery, resulting in diminishing effects.
Therefore, the effect of imidacloprid is getting smaller and smaller at present, just like the oiran is getting older step by step, and finally becomes a madam.
Among nicotine pesticides, imidacloprid is the first generation nicotine pesticide, thiamethoxam is the second generation nicotine pesticide, and dinotefuran is the third generation.
However, in the single field of imidacloprid, the current imidacloprid is an optimized product of the third generation.
That's right, it's just the third generation.
The imidacloprid rewarded in the novice mission is called the fifth generation, which means...
There is still a whole generation of technical barriers between it and the existing imidacloprid.
There is a rule in drug research and development, that is, there must be a progression between "generations", and there cannot be a leap across generations.
Just like smartphones with virtual buttons between button phones and folding screen phones, without a relay product, the gap between generations is almost difficult to bridge.
In other words.
If Xu Yun wants to turn fifth-generation imidacloprid into a new product that can be put into production, he must break through the fourth-generation technical barrier.
Xu Yun then spread the kraft paper further, hoping to see if he could get some inspiration.
"ClC1N=CC(=CC=1)CN2C...."
"Exact molecular weight 255.05200..."
Soon, Xu Yun's eyes locked on a column of Mol formulas:
70 0.0000 N 0 0 0 0 0 0 0 0 0 0 0 0
10.1936 4.2021 0.0000 N 0 3 0 0 0 0 0 0 0 0 0 0
11.3603 3.1516 0.0000 O 0 0 0 0 0 0 0 0 0 0 0 0
10.5200 5.7378 0.0000 O 0 5 0 0 0 0 0 0 0 0 0 0

6.6453 2.2238 0.0000 C 0 0 0 0 0 0 0 0 0 0 0 0 .
At the same time, a large list of information flashed through his mind quickly.
After about two minutes, Xu Yun slapped his forehead:
"Good guy, is it actually this thing?"
.......
Note:
Maybe what I said before was not detailed enough, which led some students to think that my book was very confusing, so they helped me summarize a bunch of questions...
Um, that's actually the case. Our book has always been good for reading. What I mean by Life and Death Day is not an ordinary recommendation, but the best small speaker in the new book issue. It is better than Sanjiang. Quanqidian.com has four or five issues.
There are only 7 places available for 100 books.
In addition to the small speakers, my Sanjiang and other books can be recommended on the home page, so I won’t rush to that point =.=.....
Then the results came out today. I was successfully promoted to the small trumpet. It was the same as the previous promotions. Thank you all!
Also, I got the last mol from my friends at the Pharmaceutical Research Institute. Is that rigorous?
