Chapter 409 This is a true room-temperature superconductor
Xu You can also use the same method in his subsequent research.
However, Xu You needs to add more dimensional variables.
The most important one among them is pressure.
In the previous simulation model, Xu You set the pressure of matter to standard atmospheric pressure.
Because at that time Xu You felt that the research significance of superconductivity under high pressure was not that great.
It was not until Xu You encountered the dilemma of "the upper limit of superconducting critical temperature" in his research on high-temperature superconductors.
Xu You knew that he had to find a way to break the impasse.
The research on high-pressure superconductivity may very well be a key to breaking the deadlock.
Based on the previous version of the superconducting material simulation model, Xu You continued to optimize the model.
Xu You hopes that the new version of the simulation model will not only be able to predict the superconducting critical temperature of the material, but also be able to calculate the superconducting critical temperature of the material under different pressures.
Through the deep learning function of Island AI, Island AI can give a comprehensive score to each superconducting material, just like its previous evaluation of the Go situation.
The scoring criteria are the application value of each superconducting material.
Xu You took into account factors such as the superconducting critical temperature under normal pressure, the superconducting critical temperature under high pressure, and the various properties of the matter itself.
Even if room-temperature superconductivity cannot be achieved at normal pressure, it would be a very important discovery if it could be achieved at lower pressure.
Through continuous efforts.
Xu You finally completed the new superconducting simulation model.
The new model is based on a unique algorithm of Island Artificial Intelligence, which can complete incredibly large amounts of calculations with the help of the super computing power of Island quantum computers.
This is different from the previous method of estimating the superconducting critical temperature given the structure of the material.
The new algorithm can directly infer the structure of high-resolution superconducting materials based on the island artificial intelligence's own evaluation criteria.
This way of thinking is very similar to the logic of seeking the best move in competitive games.
After completing the program writing, the next step is to wait for the island artificial intelligence to complete its calculations.
"I don't know if the island's artificial intelligence can perform as well as before this time?" Xu Youxin said.
Today's island artificial intelligence is like a scientific research assistant to Xu You, undertaking important scientific research tasks.
In many ways, Haidao AI is even better than Xu You.
Xu You vaguely felt that the island artificial intelligence was not an emotionless software, but also had its own "soul".
Solving complex computational problems is what it likes to do most.
After several days of calculations.
Island Artificial Intelligence has produced a large number of calculation results.
Xu You couldn't wait to open the software interface and browse the answers obtained by the island's artificial intelligence.
"99.6 points?"
The first thing Xu You noticed was the superconducting material that received the highest score from the island’s artificial intelligence.
And when Xu You carefully looked at the detailed results calculated by the island's artificial intelligence.
Xu You couldn't help but open his mouth in surprise.
"Under the condition of 0.1013MPa...the superconducting critical temperature reaches 258K?"
Xu You was not particularly surprised by the superconducting critical temperature of 258K.
Because in the experiment, if the pressure is high enough, the experimental team has achieved a superconducting critical temperature of the material of over 300K.
However, such ultra-high pressure is too difficult to achieve and has no practical significance so far.
But the biggest highlight of this calculation result is not the superconducting critical temperature, but the pressure.
0.1013MPa is what we usually call standard atmospheric pressure.
If the calculations of the island's artificial intelligence are correct.
This can be said to be a superconductor close to normal temperature under normal pressure!
258K at thermodynamic temperature is approximately equivalent to minus 15 degrees Celsius at Celsius temperature.
In the winter in the north, this temperature is almost the outdoor temperature.
Even compared to normal temperature in the strict sense, the temperature of minus 15 degrees Celsius is still a bit lower.
The cost required to maintain low temperatures will be very low.
Such temperatures can even be reached in the freezer compartment of a household refrigerator.
While feeling excited, Xu You still tried to keep himself calm.
First of all, this is just the calculation of superconducting materials that Island Artificial Intelligence has just carried out, and the accuracy is still unknown.
Secondly, even if the calculation is correct, it is still unknown whether this material can be prepared.
"Let's start with the material preparation issue."
Before the materials are prepared, it is impossible to verify whether the calculations of the island's artificial intelligence are accurate.
But when Xu You looked closely at the molecular structure of these materials.
A feeling of despair surged into Xu You's heart.
"Can this material... really be prepared?"
Even after all these years of progress, Xu You can already be considered a materials expert.
But Xu You had never seen a similar material structure.
If it weren't for the calculations of the island's artificial intelligence, Xu You would never have thought that such a material could be designed.
"Unfortunately, with the current capabilities of the island's artificial intelligence, it is unable to help me complete the work of material preparation." Xu You said regretfully.
In the evaluation system for superconducting materials, Xu You did not add the scoring dimension of "difficulty of material preparation".
"It seems that the problem of material preparation has to be solved by ourselves for the time being."
In the following period of time, Xu You and experts from the materials group worked together to study the preparation methods of this new material.
Compared with previous high-temperature superconducting materials, this new material is more complex and the difficulty of preparing it increases exponentially.
Some materials experts even directly concluded that this material cannot be prepared.
"Professor Xu, according to the theoretical structure diagram of this material, it has some inherent defects. These defects cannot be solved from the material preparation with current technology."
Although Xu You would not fundamentally deny the possibility of successfully preparing this material.
However, Xu You was aware of the "defects" of these materials and the extreme difficulty in preparing them.
For example, problems with the ordering of the material's various atomic layers can cause local areas to deviate from the stoichiometric ratio.
For example, because the radii of different atoms vary greatly, it may not be possible to form a stable combination of elements.
Any problem you pick out is enough for the project team to study for months.
Not to mention, putting a lot of existing problems together.
These problems caused Xu You's hope, which had just been ignited, to fall away again.
This forced Xu You to settle for the second best and study other materials with lower scores.
But apart from this material, there is no other material that can have such a high predicted superconducting critical temperature under normal pressure.
