"This graphene preparation method is more concise than the previous scheme, but the corresponding use of two carbon nanotubes as a guide growth line, the cost of macroscopic carbon nanotubes has increased greatly, and the overall cost has increased compared with the previous estimate."

Talking about the cost, Hu Feng said with some embarrassment: "We spent about 4 million US dollars on the first superconducting graphene wire, and the density of the wire is about 10th of the density of copper oxide.

The follow-up cost is reduced, and the cost of preparing one kilogram of superconducting graphene wire is not less than 9 million yuan. ”

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

Lu Yi was completely speechless, and now the superconducting coil on the stellar simulator tomorrow uses copper oxide superconducting materials, with a mass of nearly 20 tons.

Even if this kind of graphene wire is 12th of copper oxide, 9 million yuan per kilogram, it will take 18 billion yuan to completely replace the external magnetic field coil of tomorrow's stellarizer, which is 80 percent more than the initial estimate of 10 billion yuan.

"This is the limit of the price of laboratory preparation, maybe the cost of industrial preparation can be reduced, but it is not possible to carry out industrial batch preparation." Hu Feng said another bad news, that is, it cannot be prepared in industrial batches.

"Is it that the bending accuracy of the guide line needs to be too high?"

Lu Yi saw the problem of not being able to be industrially prepared, although the good characteristics of carbon nanotubes can achieve bending at the atomic level, so that the graphene monoatomic layer grown on it produces an angular difference, and finally forms a magical superconducting angle overlap of 1.05°.

However, it is clear that the bending accuracy requirement of the guide line carbon nanotubes cannot be met by the industry that is still in the nanofabrication accuracy.

Because the entire bending arc not only needs to be high-precision, but also needs to be very uniform, the slightest fluctuation can lead to the unqualified angle of the graphene layer growing on it, resulting in the loss of the peculiar superconducting angle of 1.05°.

If this alone is acceptable, the most disgusting thing is the elasticity of the carbon nanotubes themselves, and even if various stress relief methods are used, this bend will disappear and recover over time.

In addition, carbon nanotubes and graphene belong to the same kind of materials, and after guiding the growth of graphene on them, the carbon nanotubes will also form polymerization with graphene.

To put it simply, this is a disposable, or a time-limited disposable, it is impossible to open a mold like an industrial mold, and then it can be manufactured in batches according to the mold.

"The successful preparation of this superconducting graphene wire proves that our idea of making a "mold" for superconducting graphene is correct. ”

After being silent for a moment, Lu Yi waved his hand to focus the attention of all the researchers in the laboratory, looked at the group of scientific research dogs and said loudly: "Next, everyone's focus is to find a mold material from other elements or compounds that can be self-stable at the single atomic layer and meet the needs of industrial reuse.

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

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

At that time, the cash reward depends on everyone's performance but not less than one million, in this regard, you can ask your colleagues who have studied the mathematical model of plasma turbulence before, they are now all homeowners in Yangcheng!

Tell me, is there a problem finding a qualified "mold" material? ”

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.

Considering that it took Marie Curie more than a decade to extract a gram of radium, he left behind the idea of preparing enough superconducting graphene wires from the laboratory.

Although this is not as difficult as it was back then, the demand for radium is large, not a few grams, not a few kilograms, but a few tons!

"Boss! No problem! ”

Under the temptation thrown by Lu Yi, everyone was stunned, and the next moment they all roared excitedly.

There must be brave men under the heavy reward, world-renowned fame, and rewards of no less than one million, which make this group of scientific research dogs enthusiastic.

It is better to build a nuclear bomb than to sell tea eggs, the rich are concentrated in the capital circle and the business community, and most of the people who engage in scientific research are not economically rich, among which the material research dog is the most sorrowful.

Don't look at the high salary given by Lu Yi, the annual salary of each person is hundreds of thousands, but the reward of more than one million is enough for them to change 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 a few words, Lu Yi handed Hu Feng to the other side and said: "After sorting out the relevant papers involved in this superconducting graphene wire, and the patents involved, I will also talk to Xu Ying about patent registration."

In addition, in addition to keeping a part of this superconducting graphene wire, the rest is cut into multiple parts for Max Planck Laboratories, General Fusion and other laboratories that study controlled nuclear fusion. ”

The agreement signed by Lu Yi and all the scientific research members of the laboratory states that the ownership of all research results and patents in the laboratory belongs to the laboratory, and they only have the right of authorship.

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

"No, just let them know how superior the performance of superconducting graphene wires is, and it is better for everyone to find a process method for industrial preparation of superconducting graphene wires than for us to grope forward."

Research controllable nuclear fusion, materials are a big problem, relying on his own laboratory Lu Yi is confident to find a superconducting graphene mold to achieve industrial preparation of materials, but that time is not guaranteed, it may be tomorrow, or a month, a year, a few years.

Dragged on for so long, who knows if the LOW forcing system will doubt his ability and turn himself into a cute beautiful girl if he fails the mission.

The early breakthrough of controlled nuclear fusion will attract more scientific research forces and even capital forces to focus on the starry sky, and then see the splendor of Saturn's rings up close, and it will no longer be a dream to surf with pneumatic skateboarding on Jupiter's Great Red Spot.

"No problem, but I'm more confident on our side." Hu Feng nodded, looking very confident.

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

In order to research and retain talents, in addition to generous treatment, Lu Yi also followed the principle of more and more complete instruments and equipment in the laboratory.

For example, other people's laboratory tunneling electron microscopes need to apply for approval, but here they are used independently.

Of course, independent use is not casual use, each use needs to note their own purpose and use, every once in a while will be spot checked, if you find that the use of random non-compliance, then the bonus of the month will be deducted.

"That's the best, I'll give you a bonus then." Lu Yi smiled, chatted a few words, turned around and walked out of the physics laboratory, planning to go to the biology laboratory.

During this time, not only did there be a breakthrough in the stellar mimic and materials laboratory, but Zhou Ying's shaking M girl also sent a message, saying that there had been a new discovery in the research on gene error replication.
