Into Unscientific

Cockroaches generally refer to insects belonging to the order "Blattata", belonging to the phylum Arthropoda, class Insecta, and order Blattata.

This kind of creature has survived on the earth for more than 350 million years, even longer than the dinosaurs.

But in the whole ecosystem, the significance of the existence of cockroaches is actually not great.

Of course, it’s not that it’s useless—it has the property of a decomposer in nature, which can speed up the degradation of organic matter into inorganic matter.

In addition, it also has a certain value in medicine. For example, the active peptide toothpaste of Yunnan Baiyao 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, Salmonella paratyphoid A, Bacillus, Pseudomonas aeruginosa, Proteus, roundworms, hookworms, etc., and are a major disease vector, but they do not get sick.

At the same time, because the flat body of cockroaches makes them good at living in small gaps, they can survive in almost any place with water and food, so they will also get into computers, copiers, electronic scales, drinking fountains and various communication equipment and electronic instruments. .

Once they bite the circuit or components, causing 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 creatures like cockroaches.

Therefore, it is not advisable to say that cockroaches are useless, but there is no doubt that its harm outweighs its contribution.

Moreover, the decomposer attribute of cockroaches is not irreplaceable, at least in the city:

For example, mealworms can perfectly replace the role of cockroaches in corruption 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 made it very clear before that what he intends to eliminate are the cockroaches in the "living area", that is, German cockroaches, American cockroaches and oriental cockroaches, which are common pests in cities.

The reason why cockroaches cannot be eradicated is largely due to the fact that females only need to mate once in their lifetime to lay eggs for life.

After the male and female cockroaches mate, a pod-shaped thing called an ootheca grows from the end of the female cockroach's tail, and the eggs are laid in it.

A female can produce as few as 10 or as many as 90 egg cases. In one egg case, as few as 10 or as many as 50 small cockroaches can be hatched. This is why cockroaches One of the important reasons why it can't be killed.

And if pheromone can synthesize a new type of poison with imidacloprid, it will undoubtedly be a huge boost to eradicating cockroaches.

"Targeted to eliminate cockroaches."

In the office, Tian Liangwei's gaze was a bit deep. He touched his chin and asked Xu Yun:

"Don't engage in generalized research, but focus on one species, Xiao Xu, are you planning to do business?"

Tian Liangwei's tone was not a question, but it contained some opinions in a tactful manner.

In the current era, it is not impossible for scientific researchers to start a company.

On the contrary, no matter at home or abroad, competent experts almost always start their own companies or cooperate with institutions.

Making money with knowledge 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 the age of 65 who take care of the industry, and almost all experts under the age of 65 will be involved in some business territory.

For example, Tian Liangwei has a cooperative institution with 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 yuan in taxes.

However, considering Xu Yun's current age, Tian Liangwei is still not at ease that he will go to the industry at this time.

In his opinion, Xu Yun can train in the scientific research module of HKUST for a few years first.

When the experience, ability, and social connections are all clear, then consider the issue of starting a business in the sea.

Anyway, as one of the top universities in China, HKUST is still very generous in terms of scientific research treatment. There are not a few people who are worth millions at the age of 30 relying on patents, and there is no such thing as a waste of youth.

Facing his teacher's more tactful question, Xu Yun hesitated for a few seconds, and finally said:

"There is such a plan, but it is definitely not now-the fourth generation of imidacloprid has not been researched at the moment, how can we start a company without technology?

Besides, even if I want to start a business at that time, I will definitely ask our school for help, Master of Life and Death Science. "

Xu Yun's last words were considered a compliment, but they were also part of his heart.

After all, backed by the big mountain of University of Science and Technology, whether it is entrepreneurial support or their respective network resources, they are not comparable to their own efforts. Regardless of the fact that University of Science and Technology is ranked behind Qingbei Jiaofu, in terms of footsteps, University of Science and Technology, University of Science and Technology of China and Harbin Institute of Technology is the Big Three in China.

"Okay, I respect your opinion."

Seeing Xu Yun's words revealed some attitude, Tian Liangwei no longer persisted, and turned the topic back to the present:

"Tell me, Xiao Xu, what are you going to do now?"

Xu Yun took out another piece of neatly folded paper from his body, and handed it to Tian Liangwei:

"Teacher, I want to apply for a medicinal chemistry laboratory, here is the list of equipment."

Tian Liangwei took the paper, looked at it and muttered to himself:

"Conductivity meter. Gradient liquid chromatography. Drug dissolution meter, automatic refractometer, eh? Electric pulse remelting and resolidification device and ICP-MS700?"

Tian Liangwei put down the list, and tapped his index finger on the table lightly:

"Xiao Xu, other instruments are fine, but the last two things are a bit troublesome."

Electric pulse remelting and resolidification device, ICP-MS700, this is the equipment in the national major scientific research instrument development project.

The price of the latter is a little lower, more than 7 million yuan, but the price of the former is close to 15 million yuan.

If the applicant for this kind of equipment is a doctoral supervisor and an academician, then there is no problem, but Xu Yun is just a doctoral student, and he is applying for an independent laboratory. To be honest, this kind of thing is a bit over the line.

"No way, teacher."

There was also a bit of bitterness on Xu Yun's face, and he shook his head lightly:

"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. Why not 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 the ICP-MS700 once is four times that of the latter two? Don't talk about the price and compare the quality with Bentley and BYD, right?"

Then he sighed faintly, took out a separate 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 start writing when his gaze suddenly fell to the bottom right of the application form:

"Hey, teacher, that's not right."

"What's wrong?"

"Why is your personal seal stamped on this form?"

Tian Liangwei took a sip of wolfberry tea, and at the same time rolled his eyes at Xu Yun:

"How fresh, you are not qualified to apply for this level of equipment, I have evenly given you the sub-items of this year's Hundred Talents Plan, don't worry, the procedures are in compliance with the regulations.

In addition, let me tell you, be careful when you use the instrument, if you break it, you sell yourself to pay back the money, that's all, let's stop talking nonsense, don't worry about it, fill it in quickly, finish it and get out! "

Looking at Tian Liangwei who seemed impatient, Xu Yun was silent for a moment, took a deep breath, bent down and wrote the application form.

After more than 20 minutes, the application form was completed.

Tian Liangwei took the form, looked it up and down, and smacked his mouth:

"Well, it's quite decent, but you can apply for the equipment according to the specifications of the doctoral supervisor, so you don't have to think about the same level of funding. In addition, you have to gather together the R\u0026D team for independent experiments. At most, I will report you a food fee plus The last one or two team building expenses or something."

"The R\u0026D team is fine, I already have someone selected."

Xu Yun replied calmly, and then asked:

"Teacher, if the funds can't be in the same file, how much will it be reduced to?"

Tian Liangwei thought for a while and said:

"The research and development funds for biotoxins are generally distributed in stages. The first phase of the Ph.D. supervisor is about 200 to 3 million. The follow-up depends on your achievements. 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 equipment, about 300,000 yuan for materials, 50,000 yuan for miscellaneous items, and another 50,000 yuan for you from the department, a total of 900,000 yuan, including 400,000 yuan in cash flow. That's about it. . "

Xu Yun nodded lightly, and couldn't help feeling a little turbulent in his heart.

900,000 yuan, this figure is not too big for Xu Yun—not to mention 900,000 yuan in his previous life, he has participated in national projects of 90 million or even 900 million yuan.

But this time the 900,000 yuan is different from the past. It may leverage a huge blank field and help Xu Yun and countless others fulfill a lifelong obsession

Kill cockroaches!
