Chapter 307: Returning with Hope
Looking at the ultrasonic nanofabrication device in front of him, Zhao Heng couldn't help but feel a momentary expression, just two months ago, he was still a very hard-pressed low-level hospital instrument matching table, but now, he is actually in the top laboratory in China and even the world, and he can independently prepare carbon nanotubes, a high-end material that only appeared in science fiction movies or more than ten years ago.
Carbon nanotubes, is an allotrope of carbon nanostructures, length and diameter, 1,000,000 or even more than carbon nanostructures, carbon nanotubes excellent physical and chemical properties, so that these cylindrical carbon molecules in many applications of nanotechnology have new properties, especially its unique surface area, stiffness, strength and elasticity, so that carbon nanotubes in the pharmaceutical field has always been a hot topic.
For the preparation of carbon nanotubes, it is not very perfect, and the preparation methods of carbon nanotubes mainly include arc method, laser evaporation method and chemical vapor deposition method, but the preparation process conditions of these methods are relatively difficult to control, and the production quality and yield are relatively low.
Therefore, under the leadership of Professor Li Hongwei, a new method for the preparation of carbon nanotubes has been explored, that is, the ultrasonic nano preparation device, which is the silver-white instrument in front of Zhao Heng.
This instrument looks only the size of an ordinary machine tool, but it is worth at least 50 million, it can be said that this is a priceless equipment, not to mention, this equipment is independently developed by the scientific research team led by Professor Li Hongwei, in the world, the carbon nanotubes prepared by it are top in terms of quality and output.
From here, it can be seen that Professor Li Hongwei gave Zhao Heng the permission to enter here alone and operate this equipment independently, what a great trust this is.
As a medical student who graduated from a medical university, it was difficult for Zhao Heng to start with the cutting-edge technology of carbon nanotube preparation, but with the system, he had picked up the corresponding technology from Professor Li Hongwei before.
Here, I have to talk about the principle of this ultrasonic nanofabrication device, using ultrasonic waves to prepare carbon nanotubes, that is, by applying ultrasonic waves to the liquid, when the ultrasonic wave is strong enough, it will produce groups of bubbles in the liquid, each bubble is a hot spot, and it is affected by strong ultrasound at the same time.
After passing through the sparse and compressed phases of ultrasonic, the bubbles grow, shrink, regrow, recontract, and finally collapse at a high speed after multiple periodic oscillations.
In the process of periodic oscillation and fracturing, it will produce a high temperature of more than 2760C and a high pressure of about 5.05 times 10 to the eighth power, accompanied by a strong shock wave and a microjet of up to 400km/h, which will form an extremely strong mechanical stirring effect between the interfaces, which can break through the limitation of the laminar flow boundary layer and strengthen the chemical reaction process and transfer process between the interfaces, thereby promoting the decomposition of carbon atoms to precipitate on the catalyst particles and finally form carbon nanotubes.
Although the process of preparing carbon nanotubes may seem simple, this is not the case.
Not to mention anything else, the silvery-white reactor in front of Zhao Heng that can accommodate high-temperature and high-pressure reactions is not something that can be manufactured casually.
As for the one in front of Zhao Heng, Professor Li Hongwei contacted an engineering academician and entrusted this academician to lead his professional team to prepare it.
Therefore, every step of scientific research is very difficult, and many conditions must be met.
Research in a certain field has been stagnant for many years, which is normal in the field of scientific research.
But now, Zhao Heng can be said to be standing on the shoulders of giants, and the preparation and application of this nanotube is not just the result of Professor Li Hongwei alone.
Professor Li Hongwei told Zhao Heng before that his research project, to some extent, was inherited from his teacher, an old academician.
In some major scientific research fields, it may take the efforts of not just one generation, or even several generations, to break through a certain bottleneck and turn a certain theory into practical application.
The process of preparing carbon nanotubes is automatic, and as long as Zhao Heng adjusts the parameters and starts the machine, he can automatically generate carbon nanotubes in the reaction kettle.
The size of the carbon nanotube makes it directly pass through the cell membrane and enter the nucleus without causing harm to the cell, and the cell will not think that the carbon nanotube is a harmful invader.
The next step is to load the drug to be carried on the carbon nanotubes.
Because in order to realize the transportation of drugs, it must rely on two aspects of work, on the one hand, the loading of drug molecules in carbon nanotubes, and on the other hand, the transport of drug molecules in carbon nanotubes and the release at the target location, this process, also known as molecular pumping.
Regarding this research, Professor Li Hongwei led his team, which is already very mature in research, and the drug mitefucin, which is also in stock in the drug library of the biological laboratory of Yenching University, has been picked up by Zhao Heng before entering the laboratory.
In this way, under Zhao Heng's very skillful operation, at eleven o'clock in the evening, Zhao Heng finally prepared a tube of carbon nanotubes loaded with Miti Fuxing.
Looking at the time, it was already eleven o'clock in the evening, and unconsciously, Zhao Heng had been in the laboratory for five or six hours, concentrating on work, and time passed so quickly.
Zhao Heng couldn't help but look at the silver-white metal can in his hand, this metal can contains the most cutting-edge research results at present, and is loaded with carbon nanotubes of Miti Fuxing, it can be said that this kind of carbon nanotubes that can be applied in practice, even in the world, are the most cutting-edge scientific and technological achievements.
Thinking of this, a sense of pride arose spontaneously in Zhao Heng's heart, because this achievement, from the proposal of the theory, to the establishment of the project, to the current results, is independently researched by Chinese scientists, which can be said to be very valuable in the current scientific community.
After packing this can of carbon nanotubes, which can be said to be very valuable, in a metal box, Zhao Heng turned off the equipment and left the laboratory.
Carrying the metal box, Zhao Heng came to the door of Yenching University, and as soon as he arrived at the door, Zhao Heng saw that Liu Ziang was wearing a white coat and standing next to an ambulance, as if he was waiting for him.
"You're finally out, I thought I'd be here all night, and I've figured out what I'm going to eat for supper."
Seeing Zhao Heng coming out with a metal box, Liu Ziang, who was standing next to the ambulance, also breathed a long sigh of relief.
"Why don't you just come by car, why are you still driving an ambulance?"
Zhao Heng saw Liu Ziang coming in an ambulance alone, and couldn't help but hold his forehead and ask.
"Ambulance is fast, it's 。。"
Hearing Zhao Heng say this, Liu Ziang also said helplessly.
Ambulance in an emergency,It is possible to bypass some traffic rules,North City's traffic situation,If he drives his own car,Maybe when he goes back,Two or three hours may not be able to arrive,Isn't this a delay?。。
Originally, the hospital said that people from the emergency center would come by car, but Liu Ziang thought about it, and he didn't know when Zhao Heng would come out, wouldn't this occupy the quota of a driver in the emergency center?
Thinking of this, Liu Ziang found an ambulance by himself and drove over directly.
Speaking of which, driving an ambulance to pick up people is also an unprecedented thing for Liu Ziang.
Of course, in the entire Oriental Hospital, only Zhao Heng can let Liu Ziang, a big expert, personally drive an ambulance to pick him up in the middle of the night.
Only Zhao Heng has this kind of face.
"That's right, in the traffic situation in North City, even if it's 11 o'clock in the evening, only the ambulance is the fastest."
When Liu Ziang said this, Zhao Heng thought about it, it seems that this is indeed the case, I have to say that Liu Ziang is still quite reliable, Zhao Heng didn't expect Liu Ziang to have such a fine side.
"Senior, you're still quite thin."
After a pause, Zhao Heng said with some sighs.
"This is a prepared carbon nanotube? I've only seen pictures in the literature before, but this is the first time I've seen this real thing. ”
Liu Ziang stared at the silver-white metal box with a biological hazard icon printed on the surface in Zhao Heng's hand, and couldn't help but say with some sighs, what Zhao Heng is holding in his hand now can be said to be the highest achievement in the domestic medical community.
This junior can make a big move every time, which makes Liu Ziang, who has always been very high-profile, have to obey!
"Actually, it's not so mysterious, maybe in a few years, nanotherapy will become a routine treatment method in big hospitals."
Zhao Heng said very firmly.
In fact, the development of every technology will go through such a process, from the beginning of a small-scale trial, to the later large-scale rollout, this is a necessary process.
However, this time for the treatment of patients, Zhao Heng used nano therapy again, which will still cause a certain sensation in the industry.
After all, everyone is at a stage where they have never heard of nanotherapy, which can be said to be a very cutting-edge and high-end treatment method, and they must be very curious.
And Zhao Heng's small ward may become famous in the industry by then.
"You also said that it will be a few years, and now this nanotherapy is a rare thing, let's just say that the box in your hand is definitely the only carbon nanotube that has been put into actual clinical use in Beishi and even the whole country, junior, your satellite, is really big enough."
Liu Ziang said with some stagnation, even if he is a rare genius and the undisputed surgical god of brain surgery, he now has to admit that he is still a little inferior to Zhao Heng in terms of innovation.
At this moment, he really didn't know how Zhao Heng's brain was grown, how could he come up with so many whimsical and effective treatments?
Maybe there is really something different between this person!
"Or... Senior, are you going to carry it? ”
Zhao Heng saw Liu Ziang's envious look, and couldn't help but hand him the box and said.
"Uhhhh Brother,You're coaxing me as a kindergarten child.,And carry it for me.。。 ”
Liu Ziang looked at Zhao Heng a little speechlessly, however, a mysterious power drove him to involuntarily take over the metal box in Zhao Heng's hand.
It smells so good!
After all, it is a nanomaterial that has been put into use in the field of parasite treatment!
It's also good to take a look and dip it in the breath of all things.
At this moment, Liu Ziang couldn't help but think of some metaphysics.
Seeing that Liu Ziang said no, but in action, he immediately took the box, and Zhao Heng also smiled.

Waiting for the car, Zhao Heng sat in the co-pilot, and Liu Ziang put the box in his hand in the back seat.
"Junior brother, you're tired all night, rest for a while, and let me be your driver today." I dare to say that I, Liu Ziang, came to be a driver, and no one in this Eastern Hospital has ever received this treatment. How's that, seniors are good to you. ”
Liu Ziang smiled and said to Zhao Heng.
"Well, then I'll trouble you, senior."
Zhao Heng nodded, since the morning, he has been in a high-intensity work state, although he is no problem physically, but mentally, he is still a little tired, at this time, he really needs to take a rest.
Zhao Heng was lying in the passenger seat, fastening his seat belt, leaning his head on the seat, and closing his eyes, this day was too thrilling, what Zhao Heng experienced on this day, its thrilling degree may be comparable to that of ordinary people for months, or even several years.
It is in this kind of high-intensity experience that Zhao Heng has honed his heart to be extremely strong, and it can be said that now except for the destruction of the world, there is nothing that can hit Zhao Heng.
This ambulance is indeed fast, and in less than half an hour, Liu Ziang drove the ambulance to the door of the outpatient hall of Dongfang Hospital.
"Arrived?"
Between the misty lakes and lakes, Zhao Heng felt that the car had stopped, so he opened his eyes and asked Liu Ziang.
"Well, here we go."
Liu Ziang nodded.
"Half past eleven? Senior, it's only been half an hour, and you've arrived? ”
Zhao Heng looked at the time, half past eleven, he set off at eleven o'clock just now, that is to say, even if the road is smooth, it will take an hour to drive, and Liu Ziang will arrive in half an hour.
"Rest assured, the matter is special, and it has been reported to the transportation department."
As if he knew what Zhao Heng was thinking, Liu Ziang smiled and said.
"Get out of the car, Dean, they're all waiting."
After a pause, Liu Ziang said again.
"Hmm."
Zhao Heng nodded, tidied up his clothes a little, carried a metal box containing carbon nanotubes, and got down from the co-pilot of the ambulance.
This feeling is like a soldier returning triumphantly, facing the welcoming team.
It can be that this feeling of being in the spotlight is very strange, and no young person will not like this feeling.
As soon as he got out of the car, Zhao Heng saw the dean, Gao Jun, and the two vice presidents, all standing at the door waiting, and a few middle-aged people who Zhao Heng didn't know, who looked like they were from the ministry.
