It's reasonable for me to have a two-way foil for a second-level civilization, right?

……

Seeing Lu Yongchang's smooth operation, Fang Xu fell silent again.

"This...is this what you learned from the paper?"

"Didn't you say you haven't touched the experimental equipment?"

Fang Xu looked at Lu Yongchang in front of him frantically.

In just half an hour, Lu Yongchang has operated three instruments one after another.

Originally, in Fang Xu's imagination, Lu Yongchang should be a pure "theoretical worker".

That is to say, Lu Yongchang will make many mistakes in actual operation.

This situation is very common.

After all, there is an extremely huge gap between theory and actual operation.

For material science and technology, a small operation error will lead to a huge difference in the final result!

Even, Fang Xu is ready to "wipe his ass" for Lu Yongchang!

but!

The scene that happened just half an hour ago completely shattered Fang Xu's worldview!

Lu Yongchang's series of operations are as smooth as an old fried dough stick soaked in a laboratory!

Not only was there no mistake at all, but he even noticed many points that Fang Xu didn't pay attention to!

"Yes, I have never touched any experimental equipment in my life."

With a faint smile on the corner of Lu Yongchang's mouth, he said lightly.

That's right!

These so-called latest experimental equipment are left over from his previous life!

Fang Xu looked like he had eaten shit: "Then you..."

"Academician Fang, sometimes talent is very important!"

While talking, Lu Yongchang stretched out his hand and patted Fang Xu's shoulder lightly: "You understand?"

Fang Xu: "..."

After finally overcoming the shock in his heart, Fang Xu asked Lu Yongchang curiously: "Why did you choose carbon nanomaterials to achieve room temperature superconductivity?"

Hearing Fang Xu's question, Lu Yongchang slowly stopped his work, and said softly: "When two layers of parallel graphene are stacked at an angle of about 1.1°, a superconducting effect will occur."

Fang Xu's pupils shrank slightly.

"This...is this true?"

Lv Yongchang said with a smile: "You can give it a try, aren't there so many free instruments beside you?"

a few hours later.

"Oh my god... it turned out to be true!"

Fang Xu looked at the instrument screen in front of him in shock.

"Yongchang, how did you discover this phenomenon?"

Lu Yongchang leaned over to operate the equipment on the experimental table, and said softly: "I calculated it, and I have never seen the actual scene."

Fang Xu was a little speechless: "How dare you say it without seeing you?"

"Then, what if it's wrong?"

"Doesn't this mean that everything is lost?!"

"It can't be wrong!" Lu Yongchang straightened up, his eyes shone with confidence, "I have confidence in myself!"

Fang Xu: "..."

I don't know why, but since getting to know Lu Yongchang, Fang Xu feels that the time he spends speechless has increased significantly!

……

three days later.

Lu Yongchang and Fang Xu stared intently at the display screen of the scanning electron microscope.

On the screen, there is a section of matter in the shape of a cylinder!

"Yongchang, is this what you said, carbon nanotubes?"

"Are you sure this carbon nanotube can achieve room temperature superconductivity?"

Fang Xu's face was full of suspicion.

It's no wonder that he was suspicious. In fact, during these three days, he basically didn't do anything.

Apart from beating hands and running errands, the really important operations were done by Lu Yongchang alone!

As an academician who leads the team all the year round, I have to say that this is really a very novel experience!

Faced with Fang Xu's doubts, Lu Yongchang did not speak, but manipulated the microscope with a serious expression to continuously change several observation angles.

It wasn't until he saw the standard nanotube structure on the screen that Lu Yongchang breathed a sigh of relief.

"That's right, this is it!"

After all, Lu Yongchang estimated the time, with a bit of regret in his eyes.

"It's a pity, according to the current manufacturing speed, at least it will be tomorrow to see the results!"

Fang Xu glanced at Lu Yongchang's side face full of regret with a strange expression.

What a pity?

Isn't it fast enough to take out an experimental sample of room temperature superconductivity in four days? !

You must know that the time spent on the advent of any new material is calculated in years!

Chapter 17 Ten centimeters of black wire

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.

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!"

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...
