Because of the unique role of graphene, scientists even predict that it will "revolutionize the 21st century". Professor Colin-Bailey, vice-chancellor and vice-chancellor of the University of Manchester, for example, said: "Graphene has the potential to revolutionise a huge range of applications, from smartphones and ultra-high-speed broadband to drug delivery and computer chips." ”

In later history, before the cataclysm, research on this topic was a big hit, with hundreds of billions of dollars or more invested in research each year.

It can be said that this kind of material is at the level of science fiction. It takes decades or even hundreds of years to be able to truly play its huge role.

But......

I'm afraid of everything, but ......

Just when all the research was dawning, the cataclysm came.

Because of the cataclysm, almost all electronic products were scrapped, a large number of databases were destroyed, and a large number of research materials disappeared silently.

Originally, those researchers and scientists are still there, and it is not impossible to start over.

However, just after the cataclysm, the earth has undergone tremendous changes, causing huge social turmoil and hundreds of millions of deaths and injuries. Many of them include scientists and researchers who are completely incapable of self-preservation in this chaotic situation.

So that when everything settles and human beings can finally stabilize, they look back and want to develop again, only to find that on the one hand, the concentration of spiritual energy has risen, the activity of spiritual energy has increased, and the electronic technology tree must be re-climbed.

This makes it expensive and slow to re-research and re-climb the tech tree.

On the contrary, Lingneng Technology is completely in line with the environment of the times at that time, to achieve the same function, the time is shorter, the cost is less, and even the manufacturing cost after the completion of the research is much lower, in terms of competitiveness, the traditional electronic technology has almost been completely exploded.

Even so, when it was just beginning to stabilize, there were still scientists and researchers who tried to find a way to re-climb the technology tree of electronic technology and its derivatives and related technologies.

It's just that, because of the reasons mentioned before, they are still inferior to psionic technology in terms of competitiveness, so slowly, these people also disappeared, either changing their ways or dying of depression, and in the end, this effort completely failed, just leaving some electronic technology research materials under high aura activity and high aura concentration.

In fact, many places in the super energy-resistant electron tube technology and super energy-resistant transistor technology researched by Lingwu Villa are benefiting from these research materials.

At the very least, a lot of data that has to be studied for years to be available is now available in a short period of time.

Of course, Yang Chen would not be stupid enough to take it out directly to arouse suspicion, but used various methods to induce Hou Xunan to get these data. Because of this, it is not easy to say that the super energy-resistant transistor is almost mature, at least, it is not a big problem to carry out industrial production.

However, in the research of later generations, the research of graphene is very low in the schedule, so in this regard, Yang Chen really has no ready-made technical information.

However, his kinetic armor uses a large amount of graphene materials, so he can only press the burden on the madman.

Because at present, the production and preparation technology of graphene is too costly. The graphene materials used in Yang Chen's "Xuanjia" power armor before were all made by Yang Chen, a monk, who directly used the refining method to cheat. However, this method also relies heavily on the monk's cultivation and refining ability, and cannot be promoted at all. At least, for now, no one has been able to do it except Yang Chen.

With traditional scientific and technological methods, the main preparation methods of graphene include micromechanical exfoliation method, epitaxial growth method, graphite oxide reduction method and vapor deposition method. None of these methods are satisfactory. The point is that graphene is a two-dimensional crystalline material, so it is really troublesome to prepare.

Especially in the case of a larger area, the difficulty and cost of preparation will be multiplied exponentially!

Therefore, in the current international market, even laboratory-grade graphene (in 2010, graphene materials did not have a large industrial production capacity, so most of them were prepared in the laboratory for research), it is also an expensive luxury item more expensive than gold.

In China, the current average price of graphene has reached 5,000 yuan per gram, which is dozens of times that of gold, also known as "black gold". In a sense, the price of Yang Chen's reconstructive nanoceramics is no more than that. The only difference is that recombinant nanoceramics can be mass-produced, while graphene cannot.

Moreover, for every order of magnitude in the area of a piece of graphene, its average price will skyrocket by one to several orders of magnitude. The price of graphene, which is really larger, is more than 5,000 yuan per gram!

Not long ago, on December 1, 2009, at the International Conference on Materials Science held in the United States, Fujitsu Laboratories in Japan announced that they had made thousands of transistors out of graphene.

They blow the feed gas onto a substrate coated with iron as a catalyst in advance, on which a large graphene film is made. It can almost be called the world's largest monolithic graphene.

And how big is this "big" area?

The diameter is only 7.5 cm. Not even a single decimeter. It's barely the width of the palm, and it's only the horizontal width of the palm, not the length from the root of the palm to the fingertips.

How can such a width be used for large-scale use?

You must know that only Yang Chen's "Xuanjia" power armor requires a graphene monolithic area, and the minimum is more than 20 cm in diameter. The largest piece even reached a meter in diameter!

Counting on the purchase of qualified graphene products on the market. That's completely impossible.

The only way is to prepare it yourself.

The method of refining weapons, Yang Chen no longer counted on it. Because of the two-dimensional crystal properties of graphene, it is only the thickness of only one carbon atom, which requires the precision to reach the level of carbon atoms when refining the instrument.

Without strong spiritual power, at least it is also a strong spiritual power essence, superb refining technology, and exquisite micro-manipulation ability, and refining qualified graphene products, without even thinking about it.

At present, even if the cultivation progress of the people in Lingwu Mountain Villa and the speed of increasing the refining level of the weapon, it is not known that it will take the Year of the Monkey to meet the requirements.

By that time, the daylilies will be cold!

Yang Chen couldn't afford to wait.

The military can't afford to wait either.

If traditional technology is used, it is also necessary to conduct research. Regardless of the lack of funds and researchers, even if all of this is fine, well, to achieve the goal, that time is estimated to be not much shorter than the time that the previous refining method had to wait.

So Yang Chen could only find another way.

All he could think of was to rely on the spirit plant.

This is also an experience in later history.

In later history, because the electronics industry was completely finished, everything else was good, and the preparation of precision instruments, high-precision materials and parts became a big problem.

Even in the later generations, there were very few who could do similar things, and only a very small number of great refiners could do it.

But those materials, parts, and instruments are going to be mass-produced. This point is not enough for the refiner.

Therefore, scientists have studied this specifically, and in the end, this problem has been solved: relying on spiritual plants and other means similar to psionic biotechnology.

They were inspired by pre-cataclysmic biotechnology.

Before the cataclysm, biotechnology, among traditional technologies, also had methods such as the synthesis of nanomaterials with high precision requirements through various exotic organisms. The main target organisms used by scientists are microorganisms such as bacteria.

Needless to say, there are a lot of similar examples, and there are a lot of them in the tech news.

Later research went even further, and was not satisfied with just being used to make nanomaterials, but simply producing the desired parts in one step.

Due to the existence of Reiki, for biologists, the afterlife with advanced psionic technology may be regarded as a paradise.

Originally, biologists wanted to artificially cultivate a new organism, and they had to use a variety of methods, such as hybridization, bioengineering, genetic engineering, and so on. Research equipment and materials are expensive, fragile, and essential. The maintenance and use costs are enough to make investors' hearts drop. However, biological production has its own fixed laws, and the research time often has to be dragged on for a long time.

It is not without reason why scientists prefer to use microorganisms as their main research goals: after all, the life cycle of microorganisms is very short, they grow and reproduce quickly, and they are easy to produce results. Big creatures, that's different. It's okay that it takes a few months for white mice to grow, but those woody plants take a few years to grow for more than ten years, so how can they be in time?

However, not everything can be done by fast-growing microorganisms. Some things will take years, tens, or even decades. For investors who are anxious to see, it is often difficult to attract investment for this kind of project, and the development will naturally not be fast.

But in the future, all of this will not be a problem.

Think the target organism is growing slowly? No problem, you just need to increase the concentration of the aura greatly, and it doesn't matter how fast you want to grow.

Having trouble raising qualified target creatures? Simple, as long as you provide special mixed aura with different ratios, you can easily and quickly mutagenesis the target organism to produce a large number of mutations, and then you only need to keep the qualified mutations for further research.

As a result, in later generations, mechanical production, chemical production, and biological production almost equally shared the share of manufacturing. The electronic production method, which occupies a very high share in modern times, is completely missing.

Therefore, when faced with the difficulty of graphene preparation, Yang Chen thought of relying on spiritual plants to solve it.
