Chapter 1439 Advantage
The research on superconductors is also one of the most important directions for human future research, because the role of superconductors on human beings is very vast, from the most common superconducting power generation, controllable nuclear fusion, superconducting power transmission, and various maglev trains, automobiles , or even magnetic levitation skateboards, etc., as long as there is one, it can be researched.
But there is only one condition for all of this, a room temperature superconductor.
In other words, room-temperature superconductors can reach a superconducting state in a natural environment, but there is no such material at present!
A few years ago, it was reported that the double-layer graphene material achieved a superconductor at an angle of staggered by 1.1°. It seems to be a room temperature superconductor, but it cannot be regarded as a superconductor, because it needs to be manufactured under the condition of 1.7K, that is, below zero. 271.45°C.
Therefore, it cannot be regarded as a room-temperature superconductor in the strict sense. For humans, it is still very difficult to prepare at a temperature of 1K. Of course, its discovery has been working hard, but the preparation of graphene has always been relatively The cost is relatively high, and its application is more difficult, so at present, this material is not a room temperature superconductor in the strict sense.
Moreover, the three parameters of a superconductor, critical transition temperature, critical magnetic field strength, and critical current density, must be within the critical conditions at the same time for superconductivity to be established. In fact, for example, in actual use, it is possible that the natural temperature fluctuation from summer to winter will cause superconductivity to fail.
Sometimes a change of plus or minus one or two degrees Celsius will cause superconductivity to fail, but this kind of metal material can reach a superconducting state at minus 60 degrees Celsius, and more importantly, its three critical parameters are very high. , especially its superconducting temperature is very wide, which means that part of the temperature fluctuations will not interrupt its superconducting properties.
In the superconducting world, minus 60 degrees Celsius is considered an ultra-high temperature superconductor.
Because the high temperature in the superconducting world is different from the high temperature we know. Don’t let others tell you about ultra-high temperature superconductors. You will think that ultra-high temperature is hundreds of degrees Celsius.
In fact, minus 200 degrees Celsius is considered a high-temperature superconductor in the superconducting world.
Therefore, if the alloy superconductor of minus 60 degrees Celsius is mentioned, it can be regarded as a room temperature superconductor, because when the temperature in nature is minus 60 degrees Celsius, as long as the nature can reach it, it can be regarded as a room temperature superconductor.
Compared with its critical transition temperature, its manufacture can be said to be of high quality and cheap compared to all other superconductors. Of course, this is only a relative term, but if it is produced in large-scale industry, its cost will inevitably increase significantly. decline.
At that time, there will be more and more places where it can be used. Superconducting materials will greatly change human society. For example, superconducting quantum computers in the future can completely change the entire human society.
Jiang Yanhai felt like he was holding a key in his hand, but he couldn't take it out immediately, mainly because he mentioned in his acceptance speech of the National Supreme Science and Technology Award that he wanted to study controllable nuclear fusion, and then this Made it in less than two weeks...
This is a little too perverted.
The outside world didn't know what happened to Jiang Ling, but could Jiang Yanhai not know?
Therefore, he was ready to delay for a while, and he also had a backup idea, which was to find an excuse.
This excuse is nothing else, it just happens that there are aliens in that world of the prophet, and the technology of those aliens is indeed far beyond their technological level, as long as you push it there, everything can be explained.
Of course, Jiang Yanhai felt that there was nothing wrong with his research on materials, because a controllable nuclear fusion is really nothing, and there are more perverted things waiting for him to study later, so he can't push it there with any excuses.
It just so happens that the structure of this controllable nuclear fusion has been calculated in China, but they have made some mistakes in the calculation of some materials.
It is not impossible to calculate superconducting materials. In fact, before the appearance of the Pangu system, it was already a common practice in the scientific community to use supercomputing to calculate some materials that may appear superconducting. Of course, some of these calculations were accurate and some were inaccurate.
Because humanity in general knows as little about materials as it does about the universe.
Human beings currently know very little about all the material atoms. In fact, science and mythology are sometimes interlinked.
Mythology pays attention to the subtleties to see the true knowledge, pays attention to the big world, small world, pays attention to one flower and one world, one grain of sand represents one world and so on.
In fact, they all make sense.
If you really understand the microcosmic particles thoroughly, then you also understand the entire universe.
If you can really control all microscopic particles, then you can also control the entire universe, which is really not an exaggeration at all.
After storing all the data, Jiang Yanhai didn't say much. It would be best if the team that researched and designed this new controllable nuclear fusion device can develop similar materials. It is to be taken out.
I stayed in Rongcheng for another three days. During the day, Jiang Yanhai was engaged in phantom affairs with Professor Liu and the others. At night, Jiang Yanhai was studying this new material, because he found that this new material seemed to be very malleable. It is not just a superconductor, it can also be used in other fields.
On the fourth day, Jiang Yanhai and others left the research institute here, and took an early flight to go to Pengcheng. Naturally, it was impossible for Ye Cunxin and the others to enter the research institute. All the special security personnel in the research institute were responsible for relevant security work. , it is impossible for outside personnel to enter.
But when Jiang Yanhai left, Ye Cunxin and the others could naturally keep up.
When they arrived at the airport, Jiang Yanhai and the others were the first to board the plane as first-class passengers, but when Jiang Yanhai approached the plane, a dorky reminder suddenly sounded in his ears: "Warning, Commander, the plane found dangerous materials, Do you want to cancel the trip?"
Jiang Yanhai froze for a moment, dangerous material? Rather than the aircraft body dangerous? That is to say, people who have ideas about him are going to do it?
"What dangerous material?" Jiang Yanhai didn't respond at all on the surface. Anyway, Jiang Ling's personality has always been relatively cold, and everyone else knows it.
"A special coating is on the windshield of the co-pilot of the aircraft. When the outside temperature reaches a certain low temperature, the material will change drastically, which will cause the performance of the aircraft windshield to change, and the aircraft windshield will crack. " Erdan immediately gave the answer.
