Chapter 590: Difficulties in the preparation of graphene

Due to the unique role of graphene, scientists even predicted that it would "completely change the 21st century." For example, Professor Colin-Bailey, vice president of the University of Manchester, said: "Graphene has the potential to revolutionize a huge number of applications, from smartphones and ultra-high-speed broadband to drug delivery and computer chips."
In the history of later generations, before the cataclysm, research on this was a hot topic, with hundreds of billions of dollars or more of research funding invested 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 before it can really play its huge role.
but……
Everything is afraid of this one but...
At the dawn of all research, the cataclysm came.
Because of the cataclysm, almost all electronic products were scrapped, and a large number of databases were destroyed. A large number of research materials disappeared silently.
Originally, those researchers and scientists were still there, and it was not impossible to start over.
However, just after the cataclysm happened, the earth has undergone tremendous changes, resulting in huge social unrest and hundreds of millions of deaths and injuries. Many of them include scientists and researchers who have no self-preservation capabilities in this chaotic situation.
So that when all the dust is settled and humans can finally stabilize, they want to re-develop, but found that on the one hand, the concentration of Reiki increased, the activity of Reiki increased, and the electronic technology tree must be climbed again. On the other hand, a large amount of relevant data was lost , Related researchers and scientists have lost their lives, and those who survived are also struggling to survive in order to survive, almost forgetting their previous knowledge.
This has resulted in tremendous cost to re-study and re-climb the technology tree, and the speed is too slow.
On the contrary, psionic technology is completely in line with the environment of the time at that time, achieving the same function, shorter time, less funding, and even much lower manufacturing costs after the completion of research. In terms of competitiveness, traditional electronic technology Almost completely exploded.
Even so, at the beginning of stabilization, there are still scientists and researchers working hard to find a way to start re-climbing electronic technology and its derivative technology, related technology technology tree attempts.
However, because of the reasons mentioned earlier, they are still not as good as psionic technology in competitiveness, so slowly, these people will disappear, either changing their lines or dying, and finally this effort has completely failed. It just left some research materials of electronic technology under high reiki activity and high reiki concentration.
In fact, the super anti-energy electron tube technology and super anti-energy transistor technology that Lingwu Mountain Villa is studying now, in many places, benefit from these research materials.
At the very least, a lot of data that must be studied for many years can now be obtained in a short time.
Of course, Yang Chen will not be so stupid as to directly bring out suspicious sinuses, but through various methods to induce Hou Xunan to get these data. Because of this, the super anti-energy transistor is not easy to say. The super anti-energy tube technology is almost mature. At least speaking, industrial production is no longer a problem.
However, in the research of later generations, the study of graphene is ranked very low in the schedule, so in this regard, Yang Chen really does not have ready technical information.
However, his kinetic energy armor requires a lot of graphene material, so he can only press the burden on the epic.
Because at present, the production and preparation technology of graphene is really too costly. The graphene materials used in Yang Chen's "Xuanjia" power armor were all derived from Yang Chen, a monk who directly used the refiner method to cheat. However, this method also relies heavily on the monk's ability to cultivate and refine his skills, and it cannot be promoted at all. At least, for now, no one can do it except Yang Chen.
While using traditional scientific and technological methods, the main preparation methods of graphene include micromechanical peeling method, epitaxial growth method, graphite oxide reduction method and vapor deposition method. These production methods are not 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 must be turned up geometrically!
Therefore, in the current international market, even if it is laboratory-grade graphene (as of 2010, graphene materials do not yet have a large industrial production capacity, so most are prepared in the laboratory for research ) Is also an expensive luxury that is 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, and is also called "black gold". In a sense, the price of Yang Chen's reconfigurable nano-ceramics is no different. The only difference is that reconfigurable nano-ceramics can be mass produced, but graphene cannot.
Moreover, the average price of a piece of graphene is one to several orders of magnitude for every large area. Graphene with a large area really costs more than 5,000 yuan per gram!
Not long ago, on December 1, 2009, at the International Conference on Materials Science in the United States, the Fujitsu Research Institute of Japan announced that they had made thousands of transistors using graphene.
They blasted the raw material gas onto a substrate previously coated with iron as a catalyst, and a large-area graphene film was formed on this substrate. It can almost be called the largest monolithic graphene in the world.
And how big is this "large" area?
The diameter is only 7.5 cm. Not even a decimeter. The slap is barely wide, and it is only the horizontal width of the slap, not the length from the base of the palm to the fingertips.
With such a small width, how to use it for large-scale use?
You must know that only Yang Chen's "Xuanjia" power armor requires a graphene monolithic area with a minimum diameter of more than 20 cm. The largest piece even reached one meter in diameter!
Expect to buy qualified graphene products on the market. That is totally impossible.
The only way is to prepare it yourself.
Yang Chen no longer counted on the method of the refiner. Because of the two-dimensional crystal properties of graphene, it is only one carbon atom thick. This requires precision to reach the carbon atom level when a refiner is required.
Without strong spiritual power, at least it is also the essence of powerful spiritual power, superb refiner technology, and exquisite micro-manipulation capabilities. Refining qualified graphene products, you don't even need to think about it.
At present, even if everyone's cultivation progress and refining equipment level in Lingwu Mountain Village increase, then they don't know that it will take the year of the monkey to meet the requirements.
By that time, the daylily was cold!
Yang Chen can't wait.
The military can't wait.
If the method of traditional technology is used, it also needs to be studied now. Regardless of the shortfalls in funding and researchers, even if there is no problem with this, um, to achieve the goal, that time is estimated to be no less than the time that the previous refiner method had to wait.
So Yang Chen can only find another way.
All he can think of is to rely on Ling Zhi.
This is also experienced in later generations.
In the history of later generations, because the electronics industry is completely finished, others are fine. The preparation of precision instruments, high-precision materials and parts has become a big problem.
Even if they can meet similar requirements in later generations, there are very few, and only a few master refiners can do it.
Except those materials and parts, instruments, that is intended for mass production. This little refiner is not enough.
Therefore, scientists have specifically studied this, and finally, solved this problem: relying on Lingzhi and other methods similar to psionic biotechnology.
Their inspiration came from biotechnology before the cataclysm.
Before the cataclysm, biotechnology in traditional science and technology also has methods for synthesizing nanomaterials with high precision 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 in technology news.
The research of later generations is a step further, not only satisfied with the manufacture of nano-materials, but simply produced in one step and directly produce the desired parts.
Because of the existence of Reiki, for the biologists, the future generations of advanced spiritual technology may be regarded as a paradise.
Originally biologists wanted to artificially cultivate a new organism, they had to adopt a variety of methods, such as hybridization, biological engineering, genetic engineering, etc. Various research equipment and materials are expensive and fragile but essential. The cost of maintenance and use is enough to make investors feel bloodshed. Biological production has its fixed rules, and the research time must often be long.
There is no reason why scientists prefer to use microorganisms as the main research goal: after all, the life cycle of microorganisms is very short, the growth and reproduction is fast, the replacement is fast, and it is easy to achieve results. Big creature, it's different. The white mouse grows like this for a few months. Those woody plants need to grow for a few years or more~EbookFREE.me~ Where can I get it?
However, after all, not everything can be done with fast-growing microorganisms. Some things have to spend a few years or even decades. For investors who are eager to see, such projects are often difficult to attract investment, and the development will naturally not be fast.
But in later generations, all these problems will not be a problem.
Does the target organism grow slowly? No problem, just increase the concentration of Reiki greatly, no matter how fast you want to grow.
Is it troublesome to raise qualified target creatures? Simple, as long as you provide special mixed auras with different ratios, you can easily and quickly mutate the target organisms to produce a large number of mutations. Then you only need to keep the qualified mutations for further research.
So much so that mechanical production, chemical production and biological production in the later generations have almost evenly divided the share of the manufacturing industry. The electronic production method, which occupies an extremely high share in modern times, is completely missing.
Therefore, when faced with difficulties in preparing graphene, Yang Chen thought of relying on Ling Zhi to solve it. (To be continued.) To find this site, please search for "" or enter the URL:
