The next morning, Fang Xu, sporting panda eyes, pushed open the laboratory door early in the morning.
Looking at the busy researchers in the laboratory, Fang Xu's eyes showed a hint of confusion.
What about Lü Yongchang?
He quickly grabbed a researcher passing by and asked, "Where...where did Lü Yongchang go?"
The researcher looked surprised and then pointed to the depths of the laboratory.
"Professor Lü arrived a long time ago; he was already busy in the lab when we arrived!"
It's unclear when exactly, but Lü Yongchang began to be referred to as "Professor Lü" by these researchers.
Fang Xu was too lazy to correct the way they addressed each other.
After all, having witnessed Lü Yongchang's skillful and confident research methods, not only these researchers, but even Fang Xu felt a sense of admiration from the bottom of his heart!
If he hadn't known Lü Yongchang's true identity, he probably would have mistaken him for a senior professor!
After pulling himself out of his reverie, Fang Xu quickly turned to look at the wall clock.
6:45.
He clicked his tongue in amazement.
Indeed, no one's success is accidental.
Fang Xu sighed inwardly as he quickened his pace toward the depths of the laboratory.
...
Perhaps hearing the approaching footsteps, Lü Yongchang shifted his gaze from the apparatus in front of the experimental table.
He was taken aback when he saw the dark circles under Fang Xu's eyes.
What's wrong with you?
Fang Xu waved his hand with a smile, saying nonchalantly, "Hey! It's nothing! I just had a little trouble sleeping last night!"
"Why don't you go and rest for a while?" Lu Yongchang said with concern. "Anyway, there's no mission today. We just need to test the superconducting properties of carbon nanotubes."
A flicker of excitement flashed in Fang Xu's eyes, and he immediately blurted out, "Rest my ass! These dark circles under my eyes are from staying up all night because of this, and you want me to rest?!"
"Where's the wire? Let me see!"
Seeing Academician Fang's excited expression, Lü Yongchang couldn't help but chuckle.
He turned to the side, making way for the equipment on the lab table.
A glass dome with a diameter of 30 centimeters.
Fang Xu quickly stepped forward and came to the glass cover.
Through the glass cover, he could clearly see a black wire about ten centimeters long connected to two metal probes.
The wire is very thin.
To the naked eye, it is about the size of a hair.
Fang Xu reached out, curled his fingers, and gently tapped the glass cover: "Is this... a vacuum?"
Lu Yongchang shook his head and denied it, saying, "Of course not. It's just a small cleanroom right now. You wouldn't want some dust to affect the experimental results, would you?"
But he quickly added, "To be precise, it's not a vacuum environment yet."
As he spoke, Lü Yongchang pointed to the vacuum pumping equipment next to him.
Fang Xu raised an eyebrow slightly.
This sentence contains a lot of information.
"Could it be... that this material can also achieve superconductivity in a vacuum?!"
Lu Yongchang reached out and took a sheet of A4 paper covered with writing from the lab table, and handed it to Fang Xu: "According to my calculations, the superconducting wires made of carbon nanotubes are extremely stable, and their normal operating temperature range is between -50 degrees Celsius and 80 degrees Celsius."
Fang Xu's eyes lit up suddenly, and he quickly asked, "What about the air pressure?"
"Within two standard atmospheres."
"hiss!"
Upon hearing Lü Yongchang's answer, Fang Xu gasped sharply.
Good heavens!
If Lü Yongchang's calculations are correct, then these superconducting wires made of carbon nanotubes could be used in almost any corner of the earth!
Even in the extremely high pressure of the deep sea, all that is needed is to install a section of pressure-resistant pipe!
This also means that the power industry in Xia Kingdom will undergo earth-shattering changes!
"Yongchang...do you know what you've done?"
Thinking about the series of changes that would happen in the future, Fang Xu stood there blankly, muttering to himself.
A smile appeared at the corner of Lü Yongchang's eyes, but he didn't say anything.
He knew perfectly well what this wire meant!
Although these technologies are somewhat advanced for Xia Kingdom now, they are far from enough to cope with future disasters!
After admiring the carbon nanotube wires on the lab bench, Fang Xu said solemnly, "Let's begin the test!"
...
Upon learning that the first test of the room-temperature superconducting coil was about to begin, all the researchers in the laboratory put down their unfinished research tasks and gathered around Lü Yongchang.
This is a chance to witness history!
No one would want to miss such an opportunity!
Lu Yongchang swallowed hard, carefully reached out, and connected the metal probes at both ends of the wire to the testing instrument.
Although he was very confident in the materials he made, but...
In materials science, who can say for sure?
Perhaps there was an accident during the manufacturing process that caused the tilt angle of the carbon nanotubes to change by 1°, or perhaps there was some other reason...
It can be said that if even the slightest mistake occurs, the manufacturing of this room-temperature superconducting material will be considered a failure!
While his mind wandered, he turned on the switch for the testing instrument.
Power on!
A number appeared on the screen of the testing instrument.
Resistance value: 0 Ω!
It was a success!
A hint of excitement flashed in Lü Yongchang's eyes.
"Increase the current!"
Fang Xu's excited voice came from the side.
