The research of superconductors is also one of the most important directions for future research of mankind, because the role of superconductors on mankind is very broad, ranging from the most common superconducting power generation, Controlled Nuclear Fusion, superconducting power transmission, as well as various Magnetic Levitation trains, cars, and even Magnetic Levitation skateboards, etc., as long as they exist, they can be studied.
But there is only one condition for all this, Room-Temperature Superconductor.
In other words, room temperature superconductors can reach a superconducting state under natural conditions, but such materials currently do not exist!
A few years ago, there was talk about a double-layer Graphene material staggered by an angle of 1.1° to achieve a superconductor. It seems to be Room-Temperature Superconductor. In fact, it cannot be regarded as it is because it needs to be manufactured under the condition of 1.7K, which is minus 271.45°C.
Therefore, it cannot be regarded as Room-Temperature Superconductor in the strict sense. For humans, it is still very difficult to prepare at a temperature of 1K. Of course, people have been working hard to discover it, but the preparation of Graphene has always been relatively expensive, and its application is more difficult, so currently, this material is not strictly a room temperature superconductor.
Moreover, the three parameters of superconductors, critical transition temperature, critical magnetic field strength, and critical current density, must be within critical conditions at the same time for superconductivity to be established. In fact, for example, in real-life use, the natural temperature fluctuations from summer to winter may cause superconducting failure.
Sometimes a change of plus or minus one or two degrees Celsius will cause superconducting failure, but this kind of metal material can reach the superconducting state at Minus 60 Degrees Celsius. More importantly, its three critical parameters are very high, especially its superconducting temperature is very wide, which means that some temperature fluctuations will not interrupt its superconducting properties.
Minus 60 Degrees Celsius In the superconducting world, it is already 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 temperatures are hundreds of degrees Celsius or something.
In fact, temperatures of minus 200 degrees Celsius are considered high-temperature superconductors in the superconducting world.
Therefore, if the alloy superconductor at minus 60 degrees Celsius is spoken of, it can already be regarded as Room-Temperature Superconductor, because when the temperature in nature also reaches Minus 60 Degrees Celsius, anything that can be achieved in nature can be regarded as Room-Temperature Superconductor.
Relative to its critical transition temperature, its production can be said to be cheap and high-quality compared to all other superconductors. Of course, this is only a relative term, but after large-scale industrial preparation, its cost will inevitably drop significantly.
By then, there will be more and more places where it can be used. Superconducting materials will bring extremely huge changes to human society. For example, future superconducting quantum computers can completely change the entire human society.
Jiang Yan Hai felt like he was holding a key in his hand, but he couldn't take it out immediately. The main reason was that he had just mentioned in State Supreme Science and Technology Award's acceptance speech that he wanted to study Controlled Nuclear Fusion, and then he came up with it in less than two weeks...
This is a bit too perverted.
The outside world doesn't know what happened to Jiang Ling, but can Jiang Yan Hai not know?
Therefore, he was already preparing to postpone it for a while, and he also had a backup idea, which was to find an excuse.
This excuse is nothing else. It happens that there are aliens in that world, and the technology of those aliens is indeed far beyond their level of technology. As long as you push it in that direction, everything can be explained.
Of course, when it comes to materials, Jiang Yan Hai feels that it's okay to study them on his own, because one Controlled Nuclear Fusion is really nothing. There are more perverted things waiting for him to study later, so he can't just push it there with any excuse.
It just so happens that the structure of Controlled Nuclear Fusion has been calculated in China. It's just that they made some errors in the calculation of some materials.
It's not that superconducting materials cannot be calculated. In fact, before the emergence of Pangu System, using supercomputers to calculate some materials that may be superconducting was already a common practice in the scientific community. Of course, some of these calculations are accurate and some are inaccurate.
Because humans as a whole actually know as little about materials as they do about the universe.
Humanity currently understands too little about all material atoms. In fact, science and mythology are sometimes intertwined.
Mythology focuses on the subtle details to reveal true knowledge, on the big world and the small world, on one flower and one world, on one grain of sand representing one world, and other various sayings.
In fact, it all makes sense.
If you really understand microscopic particles thoroughly, then you will also understand the entire universe.
If you can really control all microscopic particles, then you can also control the entire universe. This is really not an exaggeration at all.
After all the data was stored, Jiang Yan Hai didn't say much. It would be best if the team that researched and designed the new Controlled Nuclear Fusion device researched similar materials. If they couldn't, Jiang Yan Hai would definitely have to come up with them sooner or later.
He stayed at Rongcheng for another three days. During the day, Jiang Yan Hai was working on the phantom thing with Professor Liu and the others, while at night, Jiang Yan Hai was studying this new material because he found that this new material seemed to be very malleable. It was not just a superconductor, it could also be used in other fields.
On the fourth day, Jiang Yan Hai and others left the research institute here and took the early flight to Pengcheng. It was naturally impossible for Ye Cunxin and the others to enter the research institute. The research institute had specialized security personnel who were responsible for relevant security work, and it was impossible for outsiders to enter.
But when Jiang Yan Hai left, Ye Cunxin and the others could naturally follow.
When they arrived at the airport, Jiang Yan Hai and the others were the first to board the plane as first class passengers. However, when Jiang Yan Hai approached the plane, a reminder from Er Dan suddenly rang in his ears. "Warning, Commander, the plane has found hazardous materials. Do you want to cancel the trip?"
Jiang Yan Hai was slightly stunned, hazardous materials? Rather than the aircraft body being dangerous? This means that people who have thoughts about him are going to take action?
"What kind of dangerous material?" Jiang Yan Hai didn't react at all on the surface. Anyway, Jiang Ling's personality has always been cold and cold, and everyone else knew it.
"A special coating is used on the co-pilot's windshield. 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 to break." Er Dan immediately gave the answer.
