Chapter 314

Long Jianhua is now a collection of contradictions. Many things want to do, but dare not do; Many ideas have been put forward, but they are hesitant.

In his previous research on chips and equipment, he specially sent important people to the north for investigation; In fact, Zhao Hanyuan leads people to communicate, which is also a desire for cooperation.

There is a big gap between dream and reality.

He can't even the ravine in the middle.

The original calm heart, said by Zhao Hanyuan, began to make waves again.

He is anxious, he is worried

The assembly of the pump truck needs to be done step by step. He communicated with Zhao Hanyuan for a while, then talked with Hu Fangyi for more than ten minutes, watched the assembly for a while and left.

Come to the scene to show that he attaches importance to it.

He always stays here and looks superfluous.

They are either from the project team or involved in assembly. They are all professional. What is he?

When he came to the door of the office of the Research Institute, he saw Liu Haoyu coming with a man who looked a little cramped. He was a little strange.

The man's hair is messy and his clothes are wrinkled, but from the perspective of texture, it should be of high grade.

I haven't seen this man before. He looks only in his thirties. Why is he so careless?

"President long, the doctor's name is Hu Haiyuan. He said he came to our company to look for a job and wanted to interview you."

Long Jianhua reached out and said, "Welcome! Let's talk in the office. "

Since its establishment, Chongshi Research Institute has been either introduced by acquaintances or recruited by itself; The doctor came to look for a job on his own initiative. He was the first person.

This is a good phenomenon!

Hu Haiyuan held long Jianhua's hand nervously. "Hello, Professor long. My name is Hu Haiyuan. I study new chemical materials. "

He was stunned.

I don't engage in chemical industry. It's not suitable for us.

But he said, "welcome, let's talk in the office."

Liu Haoyu left after making tea for them, leaving two people sitting on the sofa.

Hu Haiyuan is from xiangdao. He is 29 years old. He is a doctoral graduate of caliver Institute of technology in the United States. His research direction is organic synthetic polymer materials.

Because of his personality, he is not suitable for teaching. He just wants to do research.

In the United States, I have submitted many resumes, but I haven't received any reply, so I want to go back to xiangdao.

His family said that Chongshi company had a research institute, so he came to take a chance.

After listening to his introduction, long Jianhua felt that this organic synthetic polymer material was his university major in his previous life.

The Caliph Institute of technology in the United States ranks among the top five in the chemical engineering discipline in the United States, which is quite powerful.

He vaguely wanted to break his restrictions and keep him.

"Dr. Hu, there are a wide range of organic synthetic materials. What aspect did you study during your PhD?"

Hu Haiyuan took out a small folded paper bag from his pocket, opened the small paper bag layer by layer, and revealed a thin one centimeter thin sheet.

Then carefully pick up the sheet and slowly open it until it becomes five centimeters in size.

"This is the material I'm studying. This material can be used as artificial skin in the future. "

He asked with great interest, "Dr. Hu, if it is used for the skin, it should be used to repair and replace the defective skin tissue; I don't know what kind of material you use, and whether it can be quickly vascularized after use, so that you can get nutritional supply as soon as possible after transplantation. "

"If you want to use it in this area, you still need to do medical verification. Personally, I think it is not feasible to use chemical synthetic materials for artificial skin. "

Hu Haiyuan was stunned. He didn't expect long Jianhua to raise such a profound question.

Long Jianhua did not dare to say more, for fear of revealing the lack of information.

Although I studied organic synthetic materials in my previous life, I began to design after graduation, and then started my own machining plant; Apart from several fast-growing products, little attention has been paid to these.

But the basic principle is still known, but that's all.

He knows that there are two ways to produce the best artificial skin. The first is to extract collagen from patients and culture it into a piece of skin; The second is to extract the patient's skin cells and spray them on the wound to grow into skin.

Third, NASA developed a new type of artificial skin in 2008, which uses vertical carbon nanotube layers. I don't know whether it has applications.

Hu Haiyuan was embarrassed and hurriedly explained, "President long, this is not chemically synthesized, but an artificial skin made of shark cartilage and collagen in cow leather."

"This skin consists of two layers. The inner layer is collagen chondroitin material crosslinked with glutaraldehyde, and the outer layer is covered with silica gel membrane. This skin can be used as a framework for the growth of new skin tissue and vascular tissue."

"Although these new cells cannot grow the hair follicles or sweat glands usually found in the dermis. But with the growth of new skin, the raw materials in artificial skin begin to degrade and be absorbed by the body. "

Long Jianhua patted his forehead. He was preconceived that a doctor majoring in organic synthetic materials must use chemical synthesis.

Unknowingly, there was another embarrassment.

I'm sorry, I misunderstood. So, Dr. Hu's research direction is biochemistry. "

Hu Haiyuan looked at him with some formality and nodded confidently.

Because he thought the word "biochemical" seemed more accurate.

Long Jianhua pondered for a long time and looked up at Hu Haiyuan.

"Dr. Hu, our research focuses on vehicles, computers, visual and auditory products, and has nothing to do with chemical industry, because I don't like the production of a large amount of waste water and waste gas, so it's too troublesome to deal with environmental protection."

Hu Haiyuan was suddenly disappointed, and his disappointed expression was at a glance.

Long Jianhua sighed when he saw it.

This is really a person who is only suitable for scientific research. Happiness and anger are so easy to take shape.

"But you're a biochemist. I'm willing to invest and set up a special research institute."

Hu Haiyuan immediately showed a surprised expression and found a way to survive.

"Mr. long, thank me very much for this opportunity! I am willing to continue my research in this area! "

But long Jianhua didn't make him happy for a long time. He said faintly, "I just thought about it. Since you can produce skin like this, why can't you cultivate real skin? Using human skin cells or collagen is a new way. "

Hu Haiyuan looked at him with astonishment.

Slowly, his eyes glowed.

"Mr. long, your idea is too unique, but it makes sense in theory."

Long Jianhua make complaints about him.

The former is a successful research, and the latter is basically successful. Why doesn't it work?

However, the heart is still happy.

Chongshi Research Institute has another research field.
