"This graphene preparation method is simpler than the previous solution, but the corresponding use of two carbon nanotubes as the guide growth line, and the cost of macroscopic carbon nanotubes has increased significantly, and overall the cost is still higher than previously estimated."

Speaking of the cost, Hu Feng said a little embarrassedly: "We spent about 4 million US dollars on this first superconducting graphene wire, and the wire density is about one-tenth of the density of copper oxide.

The subsequent cost is reduced, and the cost of preparing one kilogram of superconducting graphene wire is no less than 9 million yuan."

"Brother Hu, are you sure you're not kidding?"

Lu Yi was completely speechless. Now the superconducting coil on Tomorrow's imitation star device uses copper oxide superconducting material, with a mass of nearly 20 tons.

Even if this graphene wire is one-twelveth of copper oxide and 9 million yuan per kilogram, it will take 18 billion yuan to completely replace the outer magnetic field coil of tomorrow's imitator, which is more than 80% more than the initial estimate of 10 billion yuan.

"This is the limit that laboratory preparation prices can reach. Perhaps industrial preparation costs can be reduced, but industrial batch preparation cannot be carried out." Hu Feng said another bad news, that is, industrial batch preparation cannot be made.

"Is the bending accuracy of the guide wire necessary to be too high?"

Lu Yi saw the problem that it is impossible to prepare industrially. Although the good characteristics of carbon nanotubes can achieve bending at the atomic level, the graphene single-atom layer grown on it creates an angle difference, and finally form a magical superconducting angle overlap of 1.05°.

But it is obvious that the bending accuracy requirement of guide wire carbon nanotubes cannot be met by the industry that is still in the nanoprocessing accuracy.

Because the entire bending arc not only requires high accuracy, but also needs to be very uniform. A slight undulation can cause the graphene layer growing on it to be unqualified, resulting in the loss of the peculiar superconducting angle of 1.05°.

If this is acceptable alone, the most disgusting thing is the elasticity of the carbon nanotube itself. Even if various stress removal methods are used, this bending will disappear and recover over time.

In addition, carbon nanotubes and graphene are of the same type of materials. After guiding the growth of graphene on it, the carbon nanotube will form polymerization with graphene.

Simply put, this is a disposable product or a limited-time disposable product. It is impossible to open a mold like an industrial mold, and then batch manufacturing according to the mold is enough.

"This superconducting graphene wire was successfully prepared, which proves that our idea of ​​making a "mold" for superconducting graphene is correct."

After a moment of silence, Lu Yi waved his hand to focus all the researchers in the laboratory here, and looked at the group of scientific research dogs and said loudly: "Next, everyone's focus will be on finding a mold material that can stabilize itself in the single atomic layer and meet industrial reuse from other elements or compounds.

Finding this elemental element or compound means that superconducting graphene materials will achieve a breakthrough in practical application in our hands. I think everyone understands what this means.

Fame, you will be famous all over the world, and reward me will not disappoint everyone.

At that time, the cash reward will be no less than one million depending on everyone's performance. You can find out about this regard about colleagues who have studied the mathematical model of plasma turbulence before. They are now home-owned families in Yangcheng!

Tell me, are there any problems finding qualified "mold" materials?”

After thinking about it, Lu Yi finally did not decide to use this method to prepare superconducting graphene wires in the laboratory. The cost is still secondary, and the time required is the main reason.

Thinking about the experience of Madame Curie taking more than ten years to extract one gram of radium, he threw the idea of ​​preparing enough superconducting graphene wires from the laboratory.

Although this is not as difficult as extracting radium in the past, the quantity demands are large. This is not a few grams, not a few kilograms, but a few tons!

"Boss! No problem!"

Under the temptation given by Lu Yi, everyone was stunned for a moment, and then roared excitedly.

There must be a brave man under the heavy reward, and a world-renowned reputation, no less than one million rewards, which makes this group of scientific research dogs excited.

It is better to sell tea eggs than to build nuclear bombs. Rich people are concentrated in the business world in the capital circle. Most of the people who engage in scientific research are not rich in economy, and among them, the materials research dogs are the most tragic.

Although Lu Yi gave a high salary, each person's annual salary was hundreds of thousands, but the reward of more than one million is enough to transform them from a promising scientific research dog to a scientific research elite who already has a car and a house.

"Brother Hu..."

After chatting with the scientific research dog in the Materials Laboratory for some reason, Lu Yi handed Hu Feng to the other side and said, "After organizing the relevant papers involved in this superconducting graphene wire, there are also patents involved, and Xu Ying will also discuss patent registration.

In addition to keeping part of this superconducting graphene wire, the rest are cut into multiple parts for Map Laboratory, General Fusion Company and other laboratories that study controlled nuclear fusion."

The agreement signed by Lu Yi and all scientific research members of the laboratory indicates that the ownership of all the results and patents studied in the laboratory belong to the laboratory, and they only have the right to sign.

"Boss, do you want them to try the thunder?"

"No, it's just let them know how superior the performance of superconducting graphene wires is. Let's look for the process method for industrial preparation of superconducting graphene wires. It's better than our family's exploration."

Researching controlled nuclear fusion is a big problem. Lu Yi, a laboratory alone, is confident that he can find materials that can be used as superconducting graphene molds to achieve industrial preparation, but that time cannot be guaranteed. It may be tomorrow, or a month, a year, or a few years.

After delaying for so long, who knows whether the LOW forced system will doubt its ability and determine that the task failed to turn itself into a cute beautiful girl.

If a controllable nuclear fusion breaks through early, it will attract more scientific research and even capital to focus on the starry sky. At that time, you can appreciate the splendor of Saturn's rings up close. Surfing with a pneumatic skateboard on Jupiter's Great Red Spot is no longer a dream.

"No problem, but I have more confidence in our side." Hu Feng nodded, looking very confident.

This confidence is not only for myself, but also for other researchers in the laboratory, but also for the equipment and instruments provided by Lu Yi.

In order to study and retain talents, in addition to generous treatment, Lu Yi also purchased the laboratory's instruments and equipment according to the principle of multiple and comprehensiveness.

For example, other people’s laboratory tunnel electron microscopes need to be approved, but they are used independently here.

Of course, self-use is not just casual use. Every time you use it, you need to note your purpose and usage status. You will check it every once in a while. If you find that you use it randomly and non-compliantly, you will deduct the bonus for that month.

"This is the best. I will give you a bonus at that time." Lu Yi smiled, chatted for a few words and turned around and walked out of the physics laboratory, intending to go to the biology laboratory.

During this period, not only did the imitation device and materials laboratory make breakthroughs, but Zhou Ying's girl, who also sent a message saying that she had made new discoveries on the research on gene misreplication.
