Early the next morning, Fang Xu pushed open the door of the laboratory with a pair of panda eyes.
Looking at the busy researchers in the laboratory, Fang Xu's eyes showed a trace of confusion.
What about Lu Yongchang?
He hurriedly pulled a researcher passing by and asked, "Lv...Where did Lu Yongchang go?"
The researcher showed a bit of surprise in his eyes, and then pointed to the depths of the laboratory.
"Professor Lu has already arrived. When we came, he was already busy in the laboratory!"
I don't know when Lu Yongchang became "Professor Lu" in the mouths of these researchers.
Fang Xu didn't bother to correct their names.
After all, after seeing Lu Yongchang's skillful and confident scientific research methods, not to mention these researchers, even Fang Xu felt a little admiration from the bottom of his heart!
If he hadn't known Lu Yongchang's identity, he would have mistakenly believed that Lu Yongchang's real identity was a senior professor!
After taking back the reverie in his heart, Fang Xu hurriedly turned his head and glanced at the wall clock on the wall.
6:45.
He was speechless to himself.
Sure enough, everyone's success is not accidental.
Fang Xu sighed in his heart, while speeding up his pace and walking towards the depths of the laboratory.
...
Perhaps hearing the sound of approaching footsteps, Lu Yongchang averted his eyes from the device in front of the test bench.
Seeing the dark circles under the eyes of Fang Xu's face, he couldn't help being taken aback.
"What's wrong with you?"
Fang Xu smiled and waved his hands, and said nonchalantly, "Hey! It's okay! I just couldn't sleep last night!"
"How about...you go to rest for a while?" Lu Yongchang said with a concerned face, "Anyway, there is no task today, just test the superconductivity of carbon nanotubes."
There was a flash of excitement in Fang Xu's eyes, and he swears directly: "Take a break! My dark circles are caused by this incident, and you still let me rest?!"
"Where are the wires? Let me see!"
Stolen from its original source, this story is not meant to be on Amazon; report any sightings.
Seeing Academician Fang's excited appearance, Lv Yongchang couldn't help laughing.
He turned sideways and gave way to the device on the experimental table.
A glass cover with a diameter of 30 cm.
Fang Xu hurriedly stepped forward and came to the side of the glass cover.
Through the glass cover, he clearly saw a black wire about ten centimeters long connected to two metal probes.
The wires are very thin.
Observing with the naked eye, it is almost like a strand of hair.
Fang Xu stretched out his hand, bent his fingers, and tapped the glass cover lightly: "It's... a vacuum inside?"
Lu Yongchang shook his head and denied: "Of course not, it's just a small clean room now, you don't want to see some dust affecting the experimental results, right?"
But soon, he spoke again and added: "To be precise, it is not a vacuum environment yet."
While speaking, Lu Yongchang pointed to the vacuuming equipment beside him.
Fang Xu raised his eyebrows slightly.
This sentence contains a lot of information.
"Could it be that... this material can also achieve superconductivity in a vacuum environment?!"
Lu Yongchang reached out and took a piece of A4 paper full of words from the experimental table, and handed it to Fang Xu: "According to my calculations, the properties of superconducting wires made of carbon nanotubes are extremely stable, and the normal operating temperature range is between Between minus 50 degrees Celsius and 80 degrees Celsius."
Fang Xu's eyes suddenly lit up, and he quickly asked, "What about the air pressure?"
"Within two standard atmospheres."
"hiss!"
Hearing Lu Yongchang's answer, Fang Xu gasped suddenly.
Good guy!
If it is as calculated by Lu Yongchang, the superconducting wire made of carbon nanotubes can be used in almost any corner of the earth!
Even in the deep sea with extremely high pressure, it only needs to install a section of anti-pressure pipeline!
This also means that Xia Guo's power industry will usher in earth-shaking changes!
"Yongchang...do you know what you did?"
Thinking of a series of changes in the future, Fang Xu stood there blankly, muttering to himself.
A smile appeared in the corner of Lu Yongchang's eyes, but he didn't speak.
He naturally knew what this wire meant!
Although these technologies are somewhat advanced for the current Xia Kingdom, it is far from enough to deal with future disasters!
After admiring the carbon nanotube wires on the test bench, Fang Xu said solemnly: "Let's start testing!"
...
Knowing that the first test of the room temperature superconducting coil is about to start, all the researchers in the laboratory put down their unfinished scientific research tasks and gathered around Lu Yongchang.
This is an opportunity to witness history!
No one will want to miss this opportunity!
Lu Yongchang swallowed slightly, stretched out his hand cautiously, and connected the metal probes at both ends of the wire to the testing instrument.
Although he is very confident in the materials he made, but...
Materials science, who can tell?
Perhaps there was an accident in the manufacturing process, which caused the inclination angle of the carbon nanotubes to change by 1°, or some other reason...
It can be said that as long as there is a slight error, the production of this room temperature superconducting material will fail!
While thinking wildly in his mind, he flipped the switch of the test instrument.
Start powering up!
A number appeared on the screen of the test instrument.
Resistance value: 0 Ω!
It worked!
A hint of excitement flashed in Lu Yongchang's eyes.
"Increase some more current!"
Fang Xu's excited voice came from the side.
Lu Yongchang immediately turned the knob and slowly increased the current.
After seeing the resistance value on the screen of the instrument without any fluctuations, all the researchers in the laboratory let out a soft exclamation.
Unlike the researchers around him, Lu Yongchang still had a serious expression on his face.
The test is not over yet.
He also needs to test how the material performs in low pressure environments!
Lu Yongchang winked at Fang Xu who was on the side.
Fang Xu nodded lightly, and turned on the vacuum equipment beside him.
With a low humming sound, the air inside the glass cover was gradually drawn out.
Seeing the value on the barometer decrease slowly, even Lu Yongchang broke into a cold sweat.
You must know that the response of superconducting materials to environmental changes is extremely violent!
For superconducting materials in the past, once the temperature or pressure changes a little, it will directly lead to the disappearance of the superconducting effect!
Under the action of such a strong current, once the superconducting effect of the wire disappears, even if the resistance value is small, extremely powerful heat will be generated instantly.
The consequence...of course, is to fuse the only room-temperature superconducting wire in the world!
Dozens of seconds later.
Looking at the calm resistance curve on the screen of the testing instrument, Lu Yongchang finally showed a bright smile on his face.
He gently wiped the sweat from his forehead, raised his right hand high, and shouted: "Success!"
"We made it!"
Fang Xu on the side turned off various instruments excitedly, rushed to Lu Yongchang's side excitedly, and patted him on the shoulder vigorously: "Good job!"
"The room temperature superconducting technology is available, Academician Fang, it's time for us to prepare for the transformation of the stellarator!" Lu Yongchang quickly withdrew from the joy of success and said in a deep voice.
Fang Xu nodded excitedly.
"I'm going to inform the staff in the laboratory that the transformation of the stellarator will start this afternoon!"
