Reborn 80s

Chen Huaiqing really didn't have time to talk to Chen Le at noon. At this time, he was visiting the laboratory in the United University.

It’s been more than two years since I last came to United University’s Chengdu campus.

The trees on campus have grown up again.

There are two more students who have left school and gone into society.

Whether society is good or not can only be known after experiencing it personally.

There are many basic research laboratories in the United University, and there is a lot of research funding in this area every year, but there is not as much funding in applied research.

As for basic research, there is a big shortcoming in investment at this time.

But there is no way, still short of money.

The most reasonable way now is to use applied research to make money to make up for the lack of basic research.

"How is the research on the industrial preparation method of graphene going?"

Graphene was first proven to exist in nature by researchers from Union University, turning theory into reality.

Naturally, it caused a heated discussion around the world.

Now that graphene has been proven to exist, all that remains is its large-scale industrial preparation.

The micromechanical peeling method, that is, using tape, is too slow.

Obviously not suitable.

Du Yongyang is quite old and his head is covered with white hair.

If he were in other universities, at Du Yongyang's age, he would have to consider retirement.

Retire when you are old enough and don't stand in other people's way.

There are only so many locations, one carrot and one pit.If the pit is occupied for a long time, the people in line behind will not be able to move.

"What we are using now is the graphene oxide reduction method."

"This method can be summarized as graphite being oxidized by a strong oxidant, and oxygen atoms enter the interlayer of graphite, combine with electrons, and break the second bond on the layer..."

Chen Huaiqing could still understand that the layers of graphite were just layer by layer, with gaps between each layer!

Looking at an object from a macro perspective, it must be a whole, airtight.

However, when observed at a microscopic level, there are gaps inside the object.

Therefore, Chen Huaiqing had no problem understanding the layers of graphite.

But what about Wu electrons, what about two bonds...

I had never heard of that before.

Chen Huaiqing really couldn't understand: "Old Du, my knowledge level is low, so don't talk about this being too professional. Just tell me what are the benefits of this graphene oxide reduction method."

When Du Yongyang faced Chen Huaiqing's interruption, he realized that Chen Huaiqing couldn't understand anything too professional.

I am used to communicating with professionals. This is a very basic concept and they just pick it up casually.

"This method is simple to operate and has low preparation cost. It can prepare graphene on a large scale. In addition, graphene oxide also has broad application prospects."

Chen Huaiqing is not very clear about the preparation of graphene.

He knew that graphene had great development prospects, but he really didn't know how to prepare it.

Just like when we use a kitchen knife, we know it is made of iron, but who cares how it is made!
Chen Huaiqing: "Can the production of graphene be carried out now?"

"It is now being produced in small quantities."

Mass production is expected to have to wait.

why?
Because the material graphene has just come out, how to use it still needs to be studied.In fact, at this time, the world is still confused about what graphene can be used for.

They are all studying it!
If you want to study thoroughly, it will definitely take a lot of time.

Only industrial demand can spur large-scale production, and now, it is obvious that industrial demand has not yet been released.

“What are the main uses of graphene now?”

To be honest, even if Chen Huaiqing knew some relevant information from later generations, he was not very clear about the future development prospects of graphene.

In later generations, it was rumored that graphene could be used as a battery, but it was only slightly added to the battery.

As for using graphene to make chips...

Something that Kage doesn't have.

I have not seen any reports claiming that graphene chips are successful.

Some people are even wondering whether graphene, a so-called new material, is a scam.

Although scientific research scams are rare, they are not unheard of.

Every time it is exposed, it is earth-shattering.

Du Yongyang smiled and said: "There are quite a lot of applications. Our basic physics research uses graphene. Some experiments that originally need to be carried out in giant particle accelerators can be carried out in the laboratory using graphene. For example, it could only be done before Quantum effects that were demonstrated theoretically can now be verified experimentally."

Chen Huaiqing raised his eyebrows: "I remember that United University published several papers on quantum research."

After so many years of continuous financial investment, it is finally bearing fruit.

Scientific research activities require continuous and stable investment. You cannot say that you will invest 100 today and not tomorrow, or the day after tomorrow you will invest 500, and the day after tomorrow you will not invest again.

The entire scientific research system cannot stand such repeated repetitions.

For example, after the disintegration of the former alliance, the entire scientific research system collapsed due to lack of funding.

A large number of scientific research talents have been lost, those who went abroad or changed careers. Anyway, the result is that their scientific research capabilities have been greatly reduced, and there is no way to develop new things and stick to their old roots.

Fortunately, the capital is strong enough. After 30 to [-] years, it is still in an advanced position in the world.

This is not to brag. The former alliance has been gone for such a long time, and the technology left behind is still leading the world. This speaks volumes.

Speaking of which, many companies under Mota Holdings still benefit from other people's legacy.

"Yes, they all rely on the characteristic that in two-dimensional graphene, the mass of electrons does not seem to exist."

"In addition, graphene also has very high application prospects in seawater desalination. We have made a graphene oxide film in the laboratory, which can form a 0.9 nanometer channel in water, and ions or molecules smaller than this size can able to pass."

Does China have a lot of fresh water resources?
If you look at the total amount, there are still a lot of freshwater resources.

However, the spatial distribution of freshwater resources is uneven, mainly concentrated in the south.

Large amounts of fresh water are discharged into the sea through the Yangtze River.

In order to solve the problem of water shortage in the north, the South-to-North Water Diversion Project was officially launched in 2002.

It took half a century from being proposed by upper-level leaders in the 50s to being formally established.

After construction begins, the construction period will not be completed in a few years, but will take more than ten to 20 years.

In the world now, only China can complete such large-scale projects with extremely long construction periods.

Chen Huaiqing looked at the graphene oxide film, which was really thin enough.

In terms of seawater desalination technology, the first step is to burn seawater, which is distilled water.

This kind of energy consumption is definitely quite large, and the cost of producing fresh water is extremely high.

The high cost can be solved with the advancement of technology. The cost of the most advanced seawater desalination technology is close to the price of tap water.
