Metropolis: My IQ is 300

Chapter 119

The chapter is right to blow Chen Fan (seeking subscription, sixth more)

The car took off, landed, returned, and strolled around the campus of Tsinghua University.

Make a circle, reverse up and down, and finally reach the ground.

This scene was filmed by everyone.

Chen Qianqian walked out of the car, eyes full of excitement.

Is this technology?

Qiu Hua and the students around him cheered, but Chen Fan was not happy, but looked at the burning ground and said: "It still doesn't work. The materials still have to be replaced. The temperature is controlled. This stability is not good, too high. NS."

"But it's done, don't care about the temperature or not, I think this is enough."

Chen Fan said: "No, the car test, this is just the beginning, the following are other tests."

The follow-up test is very simple. A huge truck drives and then hits it directly. The car is okay, then it is okay.

The loud voice was back on the Tsinghua campus.

The subsequent flame burning, low temperature and other tests, all came again.

The car was not damaged in the slightest.

Afterwards, Chen Qianqian took the gun and fired, and there were no injuries on the car.

"how did you do that?"

"Just sit there, if I tell you, this may be used in the production of clothes, and to ensure a certain degree of safety."

"Then you are the savior of all mankind, and your technology can save and protect people."

Chen Fan gave an occasional sound. In fact, this is nothing to be proud of. Carbon fiber can actually be done successfully, and the cost is high, so it has not been implemented. Now the cost has been lowered by Chen Fan. Then, the use of carbon fiber can naturally be improved.

Chen Fan pulled a student over and said, "Now I'm taking a test on you. Let me ask you how much carbon fiber production costs. Tell me more about it."

The students quickly mobilized their brains, remembering.

"There are five methods in total."

(1) Laser evaporation of graphite method: This method uses a pulsed laser to bombard the graphite surface with a metal catalyst to produce nano-scale carbon materials on the graphite surface.

(2) Plasma spray deposition method: This method is to cool the ion sprayed tungsten electrode (cathode) and copper electrode (anode) with water. When Ar/He carrier gas entrains benzene vapor through the plasma torch, it will be on the anode Deposited on the surface of carbon dust containing nano-scale carbon materials.

(3) Condensed phase electrolysis generation method: It uses graphite electrodes (electrolyzer as anode), and electrolysis of molten alkali salt with a certain voltage and current at a temperature of about 600 ℃ and argon protection conditions, electrolysis produces Various forms of carbon nanomaterials.

(4) Graphite arc method: Graphite arc method is a method in which graphite electrodes are used to discharge in a certain atmosphere to collect carbon nanomaterials from cathode deposits.

(5) Chemical vapor deposition: It is a widely used method for preparing carbon materials. It can be divided into catalytic chemical vapor deposition and non-catalytic chemical vapor deposition. When the gas (or vapor) containing the carbon source flows over the surface of the catalyst, it undergoes catalytic decomposition. Ethylene, acetylene, styrene, benzene, toluene, methane, etc. are usually used as carbon sources. These are generally chemically active compounds containing unsaturated chemical bonds; transition metals, rare metals or metal oxides are often used as catalysts; argon Gas, nitrogen, hydrogen, etc. are usually used as carrier gas. Catalytic vapor deposition does not require any catalyst, and directly thermally decomposes carbon-containing organic matter in the vapor phase under a protective atmosphere.

Chen Fan said: "So, how much are these costs?"

"The lowest cost is 20 million. Carbon fiber is different from graphene. Carbon fiber is a polymer material, and graphene is also a polymer, but the two uses are different, but the extraction methods are similar."

"Then what is the cost now."

"The production cost of one meter of carbon fiber should be between 500 and 600. If nuclear power is used as the core energy, the cost should still be very low, because the production cost of nuclear power is even lower."

Chen Fan looked at Chen Qianqian in front of him and said, "I don't know how much the equipment you have, but I can completely control the cost within two thousand yuan."

"You know, it costs three thousand yuan to buy a simple pistol in our department."

Chen Fan smiled without saying a word, and said: "But if you want to use these, it will take a long, long time. This is just an idea. During the period of material testing, etc., the practicality needs to be seen slowly. However, I think, Our topic this time is enough for them to write their own papers for themselves."

Many students at Tsinghua University waved their hands in excitement.

"Student Chen Fan, can you set up a laboratory? Or an experimental group?"

Chen Fan said: "What are you doing?"

"I don't want to go abroad, but if you study in other places in China, you can't get recognition."

Chen Fan realized that the core point was here.

The domestically recognized companies are actually Chen Fan's side.

If anyone graduated from Chen Fan, then the company will definitely be treated as an ancestor.

The car was finally handed over to Saudi Arabia. This first-generation vehicle was purchased by Saudi Arabia for 500 million yuan.

This is what Saudi Arabia forced to buy.

If the price is low, Saudi Arabia is embarrassed to take it.

Saudi Arabia, which got the car, immediately started to try.

Take a video, and then show off all kinds of.

After it appeared on Weibo, countless talents began to truly shock.

"F*ck, the car is flying? Isn't this a concept car? I remember it appeared in Dubai before."

"That was shown to be useless, it can only run for five minutes."

"But this, it seems to have been flying for a long time, and it seems that there is enough energy."

"What's the use? A Rolls-Royce costs 60 million yuan. Shouldn't this car be more expensive?"

And the final price of the car is also very interesting.

The price of 180 million.

Is it expensive? It's really expensive, but considering that the price of an airplane may be several hundred million, then looking at this car, it is actually not that expensive.

The question arises as to who is the manufacturer of this car.

Everyone thought about it for a long time, but still couldn't find a way, but Saudi Arabia said a very simple thing.

The manufacturer of this car should be Chen Fan.

Because, only Chen Fan is suitable.

This technology is impossible to sell, because it involves too many things.

"Why, why can't it be sold?"

"How can Chen Fan be so selfish? This guy has already made a lot of money, so why should he make so much."

: "I don't understand, can't we let mankind make progress together?"

The answer is simple.

"If earlier, your country could share nuclear materials, I don't think there would be so much shit."

Graphene can be used for civilian purposes, because graphene is destined to change the world, and this car is just a luxury.

And Chen Fan found the right person to help manage it.

The person in charge is Qiu Hua, and the main scientific researchers are his senior brothers and sisters.

These talents are the core.

"You actually only wanted to arrange a job for them to make this, right?"

Chen Fan nodded, sat on the sofa, and looked to the roof.

In the kitchen, Qiu Hua's wife is preparing dinner, and at this time she is pregnant, and Qiu Hua also has a child of her own.

"Why did you give it to me?"

Chen Fan said: "Your grandfather told me one thing, if you have no children, the company may give it to me in the future, but I refused. I think this is the reason you took the initiative to contact me."

"An enterprise with tens of thousands of people needs people to maintain it. Otherwise, these tens of thousands of people will be unemployed. I have no children, so you are the most suitable to manage it."

"Cultivate Chen Boming, he is the most suitable. I still own shares. I am not good at dealing with people."

At this time the food was brought up, and everyone sat down one after another.

"It's better to eat, don't talk about work, people also need to rest."

Qiu Hua nodded.

Before he knew it, Qiu Hua seemed to forget that Chen Fan was fifteen years old.

It should be said that Chen Fan will be sixteen years old soon.

Recalling the unraveling of the last Mason prime number, it was a few months ago that the shy and shy boy had grown up.

Several people sat down, Anna opened the red wine and said, "Can you give me a place for the production of cars?"

"Just divide the money."

"I know how to divide money, I will even give you a lot, but you don't think much about it?"

"What do you think about it? What do you think about it."

Tao Yaoyao pulled Anna for a while. Anna lowered her head and stopped speaking. This man really didn't understand.

0 ···Find flowers·····

Pooh, it should be this little brother.

Everyone was eating. Here, Qiu Hua's wife turned on the TV. The TV was all boasting about Chen Fan.

A genius boy or something.

Changed to a TV station, still bragging about Chen Fan.

Change to another TV station and brag about Chen Fan.

Chen Fan was a little embarrassed.

Tao Yaoyao took an order for Chen Fan.

"You still have to hold this car in your hand."

"I know that I can afford a company, otherwise, such a large industry cannot be digested. At present, there are already a lot of things being done in China."

Qiu Hua said: "I will have dinner later, walk with me, there is a place where you need to go."

"what?"

"The ribbon-cutting of the high-speed rail requires you. As the person who has completed the last link, you must be there. You will not be there anymore. It is not appropriate."

"Well, to be honest, I don't like that kind of wine bureau, it's really uncomfortable."

"I get uncomfortable. In addition, there is one more thing, your professorship, when will you deal with it."

professor?

Chen Fan suddenly discovered that this was wrong. According to normal development, he should be a graduate student, a doctorate, and then a professor.

But now this sudden professor, Chen Fan didn't understand a bit.

"Where is Cao Yuan?"

Qiu Hua explained: “I’m busy in love, graphene is resolved, and he has no face to drag the girl all the time. By the way, there is a document here. Someone gave it to me. It was given by Chen Jiaqian and said yes. A student found her and hopes to pass this information to you."

0 ...... .......

Chen Fan opened the material and began to read.

Qiu Hua's wife is very angry, what are you doing? What about eating, but also looking at work?

Chen Fan ate two bites of food and stopped.

"It’s a bit interesting, a bit interesting, using polyethyleneimine (polyethyleneimine,

PEI) nanoparticles introduce the target gene into rabbit bone marrow mesenchymal stem cells, and the transfection efficiency of the target protein is 2%~10%, while the mesenchymal stem cells treated with only the target gene have almost no expression of the target protein. Of course, simple The complex formed by the nanoparticle and the target gene has certain limitations in its stem cell transfection efficiency.

By embedding fibronectin and E-cadherin on the carbonated apatite nanocarrier/functionalized DNA complex, Kutsuzawa et al. greatly improved the efficiency of DNA transfection into mouse embryonic stem cell lines. Because there are fibronectin and E-cadherin integrins on the embryonic stem cell membrane, the modification of nanocarriers improves the probability of targeting embryonic stem cells. Green et al. [19] developed a polymer ester gene carrier, the carrier It has the characteristics of degradability and low toxicity. The chemically modified polymer ester group makes the gene transfection efficiency of this vector equal to that of the viral vector."

Qiu Hua said, "Do you understand?"

"I don't know much, but I can guess that she is a kind person."

"Why do you say that?"

"Carbon nano has always been possible in biological DNA. Her idea is to use carbon nano and then make this material into the gene sequence needed by humans, and then achieve the goal of curing diseases and saving people."

Qiu Hua smiled helplessly.

"She thinks simple."

"It's not difficult, it's just one difficulty, genes, who will interpret, who understand, who can unlock the secrets of genes?"

"That's impossible. Genes are a real forbidden zone. Moreover, genes want to be interpreted. That is definitely a big project. The program can't work... Wait, the program can work. It didn't work before. That doesn't mean it doesn't work now."

Chen Fan said: "Yes, it didn't work before, doesn't mean it doesn't work now. The gene interpretation technology has matured very early, but the computer can't calculate it. Because the program is too big, and now the computer has improved, then the gene interpretation can be done. , But the question comes again, do you think people will accept this?"

"Artificial baby? This is really a sensitive point, alas, it's a deep pit."

"Let’s eat and eat, let’s talk about it later, I think, hurry up and implement the Rockets business, this year, there must be a perfect ending."
