Cockroaches generally refer to insects belonging to the order "Blatida", belonging to the phylum Arthropoda, class Insecta, and order Blattata.
This creature has survived on the earth for more than 350 million years, even older than the dinosaurs.
But in the entire ecosystem, the existence of cockroaches actually has little significance.
Of course, that’s not to say it’s useless – it has the property of a decomposer in nature and can accelerate the degradation of organic matter into inorganic matter.
In addition, it also has certain value in medicine. For example, Yunnan Baiyao’s active peptide toothpaste contains cockroach extract. You may kiss cockroaches every day.
But these contributions pale in comparison to the harm it brings.
Cockroaches themselves carry a variety of pathogens, such as Shigella dysenteriae, Salmonella Paratyphi A and B, Pseudomonas aeruginosa, Proteus, roundworms, hookworms, etc. They are a major disease vector, but they do not get sick themselves.
At the same time, because the flat body of cockroaches makes them good at living in small gaps, they can survive almost anywhere there is water and food. Therefore, they will also get into computers, copiers, electronic scales, drinking fountains and various communication equipment and electronic instruments. .
Once they bite the wires or components and cause a short circuit, it will lead to equipment failure, communication interruption and other unexpected accidents.
Behind almost every plague in history, you can see the dancing wings of cockroaches.
Therefore, it is not advisable to say that cockroaches are useless, but there is no doubt that their harm outweighs their contribution.
Moreover, the cockroach’s decomposer attribute is not irreplaceable, at least in the city:
For example, mealworms can perfectly replace the role of cockroaches in decomposition factories, and the cost is even lower.
As for cockroaches in nature...
Then it is not within the scope of Xu Yun's elimination.
Xu Yun had made it very clear before that he planned to eliminate cockroaches in the 'living area', which were common pests in cities such as German cockroach, American cockroach and Oriental cockroach.
A large part of the reason why cockroaches cannot be eliminated is that females only need to mate once in their lives to lay eggs for life.
After male and female cockroaches mate, a pod-like thing called an ootheca will grow from the tail end of the female cockroach, and the eggs will be laid in it.
A female can lay as few as 10 or as many as 90 egg sheaths. In one egg sheath, as few as 10 or as many as 50 small cockroaches can be hatched. This is why cockroaches One of the important reasons for not killing them all.
If the pheromone can be synthesized with imidacloprid into a new poison, it will undoubtedly be a huge help in eradicating cockroaches.
"Targeted eradication of cockroaches..."
In the office, Tian Liangwei's eyes were a little deep. He touched his chin and asked Xu Yun:
"Instead of conducting general research and focusing on one species, Xiao Xu, are you planning to go into business?"
Tian Liangwei's tone was not a question, but he tactfully gave some opinions.
In this era, it is not a big deal for scientific researchers to start a company.
On the contrary, whether domestic or foreign, capable experts almost always open their own companies or cooperate with institutions.
Using knowledge to make money is like licking your own teacher, not shabby.
In China, the age of 65 is almost used as the dividing line. There will be fewer top scholars over 65 who are also involved in industry. Almost everyone under the age of 65 will be involved in some business areas.
For example, Tian Liangwei has a cooperative institution with the Jilin University School of Medicine, which specializes in research on NK cells. Everything is legal and compliant, and there is no need to pay more than one billion in taxes.
However, considering Xu Yun's current age, Tian Liangwei is still not sure that he will start the industry at this time.
In his opinion, Xu Yun can first train in the scientific research module of HKUST for a few years.
After you have a clearer understanding of your experience, abilities, and social connections, you can then consider starting a business overseas.
Anyway, as one of the top universities in the country, HKUST enjoys very generous scientific research benefits. There are many people in their thirties who are worth millions by relying on patents. There is no such thing as a waste of youth.
Facing his teacher's rather tactful question, Xu Yun hesitated for a few seconds and finally said:
"There is a plan, but it is definitely not now - the fourth generation of imidacloprid has not been developed yet. How can we start a company without technology?
Besides, even if I want to start a business at the wrong time, I will definitely seek help from our school, the University of Science and Technology of Life and Death. "
Xu Yun's last words were considered a compliment, but they were also partly from his heart.
After all, with the big mountain of HKUST at his back, whether it is entrepreneurship support or personal network resources, nothing can be compared to what he can do alone - even if HKUST is ranked behind the Qingbei Jiaofu, in terms of heel alone, HKUST, NUUST and NU Harbin Institute of Technology is the top three in the country.
"Okay, I respect your idea."
Seeing that Xu Yun's words revealed some attitude, Tian Liangwei stopped insisting and turned the topic back to the present:
"Tell me, Xiao Xu, what are you going to do now?"
Xu Yun took out another neatly folded piece of paper from his body and handed it to Tian Liangwei:
"Teacher, I would like to apply for a medicinal chemistry laboratory. Here is the list of instruments."
Tian Liangwei took the paper and read it while muttering to himself:
"Conductivity meter... gradient liquid chromatograph... drug dissolution meter... fully automatic refractometer... hmm? Electric pulse remelting and re-solidification device and ICP-MS700?”
Tian Liangwei put down the list and tapped his index finger lightly on the table:
"Xiao Xu, the other instruments are fine, but these last two things... are a little troublesome."
Electric pulse remelting and re-solidification device, ICP-MS700, is a piece of equipment included in a major national scientific research instrument development project.
The price of the latter is lower, more than 7 million, but the former is close to 15 million.
If the applicant for this kind of equipment is a doctoral supervisor, there will naturally be no problem. However, Xu Yun is just a doctoral student, and he is applying for an independent laboratory. To be honest, this is a bit over the line.
"There's nothing we can do, teacher."
A trace of bitterness also appeared on Xu Yun's face, and he shook his head gently:
"The short-term precision of ICP-MS700 is much higher than that of ICP-OES and GFAAS, and it involves matrix acid interference of methyl groups. The advantages of ICP-MS are really far ahead. How can I compare to these two devices?"
Tian Liangwei glared at him angrily:
"Yes, yes, the equipment is easy to use, but why don't you say that the cost of starting up the ICP-MS700 is four times that of the latter two? Let's compare the quality of Bentley and BYD without talking about price, right?"
Then he sighed quietly, took out an independently stored application form from the drawer, and pushed it in front of Xu Yun:
"Fill it in."
Xu Yun took the form and was about to write when his eyes suddenly glanced at the bottom right of the application form:
"Hey, teacher, that's not right."
"What's wrong?"
"Why is this form stamped with your private seal?"
Tian Liangwei took a sip of the wolfberry tea and rolled his eyes at Xu Yun:
"How new. You are not qualified to apply for an instrument of this level. I will give you the quota for the auxiliary items of this year's Hundred Talents Plan. Don't worry, the procedures are in compliance with the regulations.
In addition, I tell you, be careful when using the instrument. If it breaks, you will have to sell yourself to pay back the money. Okay, okay, stop talking nonsense, stop whining, fill it in quickly, and get out of here! "
Looking at Tian Liangwei who looked impatient, Xu Yun was silent for a moment, took a deep breath, and leaned down to write the application form.
After more than twenty minutes, the application form was completed.
Tian Liangwei took the form, looked up and down a few times, and then smacked his mouth:
"Well, it's quite decent, but the instruments can be applied for according to the PhD supervisor's specifications, and you can't even think about the same level of funding. In addition, you have to raise the R&D team for independent experiments yourself. At most, I'll give you a meal fee plus The last one or two team building expenses and so on.”
"There is no problem with the R&D team. I already have a candidate."
Xu Yun replied calmly, and then asked:
"Teacher, if the funding cannot be the same, how much will it be reduced to?"
Tian Liangwei thought for a while and said:
"Funds for the research and development of biotoxic agents are generally released in phases. The first phase for a doctoral program is about two to three million. The follow-up will depend on your results. It is not impossible to reach hundreds of millions at the Nobel Prize level.
As for you...I will try my best to get you 500,000 yuan for instrument funding, about 300,000 yuan for materials, 50,000 yuan for miscellaneous items, and the department will give you another 50,000 yuan, for a total of 900,000 yuan, including cash flow. Four hundred thousand, that's pretty much it. "
Xu Yun nodded slightly, feeling a little egg rising in his heart.
900,000 yuan is not a big figure for Xu Yun - let alone 900,000 yuan in his previous life, he has participated in national projects worth 90 million or even 900 million yuan.
But this time the 900,000 yuan is different from the past. It may open up a huge blank field and help Xu Yun and countless people complete a lifelong obsession...
Kill cockroaches!
