Chapter 218 I regret that I shouldn't have questioned you
Xu You had known about the existence of this device for a long time, but it was the first time he saw it in person.
Previously, American scientists used this device to achieve very high pressures when conducting ultra-high pressure room-temperature superconductivity experiments on hydrides.
In addition to the equipment, the project team also received a large amount of diamonds to help create ultra-high pressure conditions.
The reason why the diamond anvil can create an ultra-high pressure environment is that when two diamonds are in contact, the contact surface is very small and the area of the mechanical pressure part is large, which can make the diamond pressure chamber obtain high pressure.
Such a device is very expensive.
Diamonds are like consumables.
Of course, compared with 202K superconducting materials, diamond is not that precious.
This type of diamond anvil can have insulating material added into the sample chamber.
In this way, as long as the high temperature area does not exceed the sample cavity, the diamond will not be damaged even if the temperature exceeds the melting point of the diamond.
Xing Shuping gathered everyone together and explained the experiment to be conducted.
"Today, we are going to do some ultra-high pressure forming experiments on 202K superconducting materials. We will gather in the laboratory later."
Everyone knows that this plan was Xu You's idea.
Everyone is looking forward to whether today's experiment can achieve a breakthrough.
Chen Pingqiu also hopes that this project can achieve a breakthrough.
Even if Chen Pingqiu didn't believe it, Xu You could really achieve a breakthrough in material forming technology in such a short time.
But as a member of a team, who wants to see the project fail?
After everyone arrived at the laboratory, Xing Shuping organized the experiment.
"Let's first take a look at the performance of 202K superconducting materials under ultra-high pressure. Professor Chen Pingqiu, you will be in charge of the operation of the diamond anvil."
"Okay, Academician Xing."
The operation of this equipment is very delicate. If there is even the slightest mistake, the two diamonds may be ruined.
Although the project team has ample funds, they certainly cannot be wasted like this.
Xu You also knew that he had no operating experience at all, so it would be better not to get started.
Chen Pingqiu had used this type of equipment before and was the most experienced operator in the entire project team.
In matters like this, experience is indeed more important.
Under the leadership of Chen Pingqiu, the experiment began.
Chen Pingqiu placed the 202K superconducting material in the sample chamber of the diamond anvil, preparing to increase the pressure.
At this time, the computer connected to the device synchronously displays the temperature, pressure and other conditions in the sample box.
The microscopic morphology of the 202K superconducting material is also displayed on the computer screen.
As the pressure continues to increase, the 202K superconducting materials begin to gather together.
Until the pressure reaches 100GPa, the molecules of these materials have completely aggregated together to form a more continuous material structure.
Under such high pressure, the molecular structure of the 202 K superconducting material has undergone slight changes, but there has been no change in the molecular formula.
"It's okay, Professor Chen, please restore the normal pressure environment." Xu You said.
Although Xu You did not personally participate in the experiment, he was the leader of the experiment.
Chen Pingqiu could only follow Xu You's orders and carry out his operations.
When the pressure gradually returns to normal pressure.
The 202K superconducting material that had just gathered together dispersed again.
The molecular structure also returned to its previous form.
"Sure enough, it is exactly as predicted." Xu Youxin said.
The changes that ultra-high pressure brings to this material are only temporary.
As long as the pressure returns to normal pressure, the properties of the material will also be restored and they will not continue to aggregate together.
The application of ultra-high pressure is like putting a lock on the material, and when the pressure is removed, the lock is automatically unlocked.
Next, Xu You will use another method to "weld" the lock.
"Professor Chen, please continue to apply 100GPa of pressure."
At this time, Chen Pingqiu was like Xu You's assistant, accepting Xu You's instructions.
Chen Pingqiu vaguely felt that such a relationship seemed to be a disadvantage for him.
But he was the best at operating the diamond anvil in the group, so he had no choice but to continue following Xu You's instructions.
Just like last time, after reaching a high-pressure environment of 100GPa, the 202K superconducting material aggregated together again.
This time, Xu You applied the "key" conditions previously calculated by supercomputing to the sample chamber of the diamond anvil.
It is not possible to see any changes in the material's microstructure from the computer screen.
"Professor Chen, we can restore normal pressure conditions."
At this time, everyone's eyes were focused on the screen.
If the material can remain polymerized after returning to normal pressure conditions.
This shows that Xu You’s plan is effective.
However, at this time, everyone lacked confidence in Xu You.
After all, it is just adding a set of conditions.
Even if there really is such a "key", the probability of it being found is much smaller than guessing the password of a bank card you picked up on the street.
Moreover, from the screen, it seemed that the microstructure of the material did not change at all after Xu You imposed a set of conditions.
Even Xing Shuping didn't quite believe that this experiment could be successful.
As the pressure in the sample chamber gradually decreases.
Everyone silently hoped that these materials would not be dispersed any further.
What’s different from last time is.
This time, the material did not begin to disperse immediately.
Until the pressure approaches normal pressure, the previous aggregation state is still maintained.
At this moment, everyone held their breath.
Chen Pingqiu also set his eyes on the screen.
See that the material remains polymerized.
Chen Pingqiu also found it a little unbelievable.
"Really...successful?"
Chen Pingqiu was sure that he had removed the ultra-high pressure conditions and restored the normal pressure environment.
Since the material did not disperse again.
This proves that Xu You’s method is really correct!
At this time, Chen Pingqiu felt a little regretful that he should not have questioned Xu You before.
It’s amazing that I can become the chief researcher of a project of this level at this age.
It only shows that Xu You's ability has reached the pinnacle level.
After all, my decades of experience are no match for Xu You's research results in just a few months.
Xing Shuping, Qiao Sen, and other professors in the laboratory.
They all looked excited.
Xing Shuping was glad that he chose to continue exploring the molding process of 202K superconducting materials.
I am also glad that I have always believed in Xu You, this young man who is almost omnipotent.
However, Xu You himself was the calm one.
Xu You knew that the experiment was not over yet.
"Once I remove this set of additional conditions, if the material still doesn't fall apart, then this experiment can be considered a success." Xu You said.
