Chapter 204 200K!
Two years passed, and Xu You graduated before he had a chance to fully experience campus life.
Fortunately, in the following period of time , Xu You simply changed his status to a doctoral student, and there was no other essential change.
Wearing his bachelor's gown, Xu You returned to dormitory 208.
Xu You didn't have any special ideas, he just wanted to go back to the dormitory and change out of this bachelor's gown.
Xu You no longer had any interest in things like taking graduation photos.
Those who took graduation photos were all seniors in their senior year.
Xu You would inevitably seem out of place here.
When Xu You returned to the dormitory, his roommates were filled with mixed emotions when they saw him wearing a bachelor's gown.
Xu You's roommates must be happy for the fact that he was able to graduate from college two years early.
At the same time, they were also very envious of Xu You.
While they were still busy with their sophomore final exams, Xu You was about to get his bachelor's degree.
In addition, they also knew that Xu You would have to move out of Room 208 and move to the graduate dormitory after this.
"Xu You, are you back to pack your things?"
"Pack your things? Oh, by the way, let me tell you something. I have signed an agreement with the school and will not be moving out of this dormitory. So even if I go to graduate school, we will still be roommates."
Upon hearing the news, Liu Rui, Guo Haochen and Zhao Xiaohui all laughed excitedly.
"So we can still be roommates for two more years? That's great!"
Although Xu You did not often stay in the dormitory after renting the house.
But as long as Xu You's luggage remained in 208, the feeling would be completely different.
"Hey, Xu You, have you taken graduation photos?" Liu Rui asked.
Xu You shook his head and said, "No, there's nothing to take pictures of myself. I can't just take selfies. This is just a ceremony, it doesn't matter."
"No, that won't do. This is a very memorable moment in life. We can't miss it. Come on, let's take a photo with you!"
"Won't that delay your final review?"
"It's okay. It won't take more than a few minutes, right?"
Guo Haochen and Zhao Xiaohui also nodded in agreement.
Such moments are indeed worth commemorating.
Not to mention, taking a photo with someone like Xu You.
"By the way, Xu You, call your female classmate as well. She definitely doesn't want to miss such an important moment."
"Lu Zhiyao...then ask her."
Xu You didn't know whether this would disturb Lu Zhiyao.
But if I don’t tell Lu Zhiyao, it would seem like I’m not being a good friend.
Thinking of this, Xu You sent a message to Lu Zhiyao on WeChat.
[Xu You: I've finished my graduation ceremony. Do you want to take some photos together as a souvenir?]
[Lu Zhiyao: Yes, you must be lonely graduating alone, right? It's a good opportunity for a cat to keep you company.]
[Xu You: If you hadn’t mentioned it, I would have almost forgotten. I’ll call you later, along with a few of my roommates.]
[Lu Zhiyao: OK, see you later]
After a while, Xu You and others came outside.
Liu Rui brought his own SLR camera with him on purpose, hoping to take better-looking photos.
Xu You called Lu Zhiyao on WeChat.
Soon, Lu Zhiyao came downstairs .
"Sister-in-law is so beautiful..." Liu Rui couldn't help but sigh.
Lu Zhiyao looked exceptionally beautiful today, and her makeup was just right.
It was also the first time that Lu Zhiyao officially appeared in front of Xu You’s roommates, and she was a little shy.
"Come on, let me take a few pictures of the two of you first."
As he spoke, Xu You and Lu Zhiyao took a lot of photos together.
Xu You still remembers that when they were in high school, both of them had the dream of being admitted to Ji University.
This dream seemed a bit out of reach at first.
Now, all of this has become a reality.
Next, the group took many photos at various memorable places in Ji University.
Including the cat living downstairs in Lu Zhiyao’s dormitory, it also took several photos with everyone.
After returning to Heqing College, Xu You thought of Dean Jiang Hong and counselor Sun Bingkun.
In the past two years, the dean and counselors have also provided Xu You with a lot of help.
Xu You also took photos with them separately.
And when the students of Heqing College learned that Xu You had graduated.
They also found Xu You and wanted to take photos with him.
Xu You had no reason to refuse.
It was fine at the beginning, we could take photos one by one.
Later, as the number of students increased, we could only take group photos together.
…
After finishing graduation matters.
Xu You can finally devote his energy back to the superconductor project.
As batches of calculation results of superconducting materials come out.
More and more superconductors are being discovered.
And their superconducting critical temperature is constantly setting new records.
From 160K, to 170K, to 180K...
These remarkable discoveries have made high-temperature superconductors no longer rare.
Xu You was also waiting for the appearance of the first superconductor that broke through the sublimation point of dry ice.
finally.
In the fifth batch of calculations, we discovered.
The superconducting critical temperature of a material reaches an astonishing 200K.
"200K! It has exceeded the sublimation point of dry ice!"
After more and more high-temperature superconductors were discovered.
This news is undoubtedly a more shocking news.
Although 200K is only 5K higher than 195K.
But this is a qualitative leap.
If this substance can actually be prepared and put into use.
That will mark the beginning of a new era for superconducting technology.
Dry ice era!
By using dry ice as a refrigerant, the cost of superconductivity will be greatly reduced.
Even this cannot make superconductivity accessible to the general public.
But for many industries, this is definitely a technology with great utilization value.
"We can put the research on other superconducting materials on hold for now. Let's focus all our current energy on the preparation of this new material."
In comparison, previous superconductors with superconducting critical temperatures below 195K now seem less important.
After all, the difference between being able to break through the temperature threshold of 195K is really huge.
After hearing the news, the professors in the team were very excited and expectant, and focused all their energy on the preparation of this new material.
With previous experience in preparing these materials.
It is no longer so difficult for us to prepare new materials.
Because these superconducting materials are relatively similar in structure.
The difficulties encountered in the preparation process are also relatively similar.
This time, the time it took to successfully prepare the new material was even shorter than those of previous materials.
After completing the preparation of the materials, everyone came to the Condensed Matter Physics Laboratory of Ji University again.
