Chapter 181 Mysterious Superconductivity

After explaining the "superalloy" series of materials, several people walked forward a few steps and suddenly saw a white platform and a suspended black stone!

This is the core combination in the center of the entire hall: the stone is gray-black, ordinary, that is, ordinary ore.

However, it is completely suspended in the air!

If you are not informed, you will mistakenly think that this is anti-gravity technology, but in fact it is not...

The stone is supported by a small ring below, and this semi-metallic ring is what humans dream of...

Superconducting materials at room temperature and pressure!

The brilliance of a superconducting material almost overshadows the 17 pieces of the "superalloy" series, and even Dr. Rambo has a mysterious embarrassment on his face.

Superconductivity at room temperature and pressure is the crystallization of cross-era technology!

Dr. Rambo is really convinced. This epoch-making achievement, such a highly complex material, I don’t know how it was developed...

There are also superconductors at room temperature and pressure in the materials of the Mars UFO, but they are all fragmented, and the process is extremely complicated, and humans have no way to imitate it.

Just like primitive people facing a modern laptop, there is no way to make one exactly like it. This is completely due to the lack of theory and technology.

But now... it has been done inexplicably? !

A large group of scientists gathered around the boulder and discussed excitedly, even shouting.

These are experts in electromagnetics and materials science. Their faces flushed, and they made exaggerated gestures and uttered a lot of professional terms.

They deeply understand the epoch-making significance of superconducting materials!

This is real superconductivity at normal temperature and pressure! To be precise, it needs to be under standard atmospheric pressure and below 15 degrees Celsius to work.

But this is enough. This superconducting condition is not much different from normal temperature and pressure...

Many scientists who observed superconducting materials for the first time beat their chests and stamped their feet in front of this boulder, wishing they could study it immediately.

For them, the appearance of a superalloy series at the exhibition is still conceivable, but... superconductivity?

It's really unexpected!

They have a feeling of going crazy.

It can be said that almost any cutting-edge technology in the future will require the support of superconducting materials. For example: controlled nuclear fusion technology, ultra-high-speed electromagnetic guns, high-power laser pulses, quantum computers, etc. If there is no superconductivity, these technologies are just mirages and can only exist in imagination.

At room temperature, the best conductive material is metallic silver, and the resistivity of silver is 1.5 at 20°C. But this resistance is still too large for some ultra-high-power weapon-grade equipment.

As long as there is resistance, the conductor will heat up. Heat is fatal to high-tech devices!

Like weapon-level laser pulse devices, the instantaneous power reaches hundreds of millions of watts. Just a small amount of resistance will generate a lot of heat, creating the risk of conductor melting. Such devices are unstable, affecting the final power and accuracy.

Using superconducting wires without resistance can completely avoid these problems.

In addition, in addition to the characteristic of "zero" resistance, superconductors are also completely anti-magnetic, which is also the basic principle of the suspension of this boulder!

Since superconductors "do not allow" any magnetic field inside them, if there is a magnetic field from the outside world to pass through the inside of the superconductor, then the superconductor will inevitably generate a magnetic field opposite to it to ensure that the internal magnetic field strength is zero, which forms a repulsive force.

Such repulsive force can be used to fight against gravity!

When a magnet is placed directly under a superconductor and the magnetic flux lines pass vertically through the superconductor, the superconductor will obtain vertical buoyancy!

There was once a movie called "Avatar", which depicted a huge rock floating in the sky, which was caused by room-temperature superconducting materials...

Superconductivity, the strongest bottleneck for mankind to move towards the era of electricity and magnetism, was inexplicably and easily overcome, making many people feel unreal.

Yu Yifeng and others listened to the discussion of this group of scientists. Some people lamented the ups and downs of this difficult road, and also had a beautiful vision of the future... Many people felt that this road would take a long time to go, and would continue for dozens or hundreds of years, but it was suddenly completed, which made people feel very dreamy.

Yes, very dreamy...

Everyone thought so. In fact, humans at present have never thought about overcoming this problem.

But now it has been done abruptly and inexplicably...

The origin of superconductivity comes from 1911. Kamerlin Onnes of Leiden University in the Netherlands accidentally discovered that when mercury is cooled to minus 268.98℃, the resistance of mercury suddenly disappears. This phenomenon is called superconducting state.

For this discovery, he won the Nobel Prize in 1913, and also opened the prelude to the research of superconducting materials.

Now, more than a hundred years have passed, and people's progress cannot be said to be great. When room-temperature superconductivity is still a long way off, it is unexpectedly conquered by a newly emerging genius, which is really a pity.

Just like a twisted mountain road with no end in sight, scientists just want to run to the end step by step for hundreds of years. But someone suddenly opened the cheat and used an airplane to directly cross tens of thousands of kilometers to reach the end...

Yes, that's it, that's how scientists feel... There is a sense of fantasy and inexplicable emptiness.

The structure of this superconducting material is extremely complex, and similar structures have never appeared before. It is a high molecular polymer with silver as the core. The molecular formula is ****, and it is a large molecule composed of a total of one million atoms!

The most peculiar thing is that a hexagonal "high-speed channel" is formed between molecules, and electrons can pass through the high-speed channel quickly with almost no obstacles... So superconductivity at normal temperature and pressure is formed.

It is indeed the case in a simple explanation, but scientific theory cannot be explained so simply.

This research report on superconducting materials is confusing, and the part about the specific principles is also vague. So even the inventor himself does not know how this "high-speed channel" between electrons is formed, as if it was discovered by accident...

But the report itself, but detailed description of the manufacturing process of this superconducting material, after verification, it is indeed feasible.

Yu Yifeng was also very interested in the inventor when he heard the scientists talk. Just like a blind cat encountering a dead mouse, is it just luck that solves this big problem?

Yes, it is so magical and weird...

But the probability of this happening is not to say that it does not exist, it can only be said to be very, very low, it can no longer be calculated in one in a billion, but one in a hundred billion or one in a trillion! It's as weird as a monkey randomly typing on the keyboard and typing out a beautiful article!

"Do otakus change the world?"

"Maybe it was guided by God that gave me such inspiration..."

Scientists are talking about it...Except, except for luck, there seems to be no other explanation.

Yu Yifeng frowned and looked at the personal information of the inventor. This guy named "Zhang Peng" is a super otaku, usually working as a researcher at the Huguang Supercomputing Center.

Yes, a researcher in information engineering! Not a researcher in materials science? !

Usually, this Xu Peng is also mediocre, but this time, he suddenly got the hang of it or opened up, and researched this superconducting material across industries? !

I don't know if it's a peerless genius or a peerless good luck? !

It's very weird!

What disappointed many scientists was that this otaku didn't even attend the material release conference this time, choosing to stay in his house and maintain a strange sense of mystery...

Yu Yifeng shook his head, feeling very confused.

He really had very little impression of Zhang Peng. It's not that he didn't know him, but he only knew this person.

Moreover, this guy was brought from the earth to the moon by the "Victory" spacecraft, and was one of the hundreds of survivors who escaped from the earth by chance.

He thought about it carefully, and although he wanted to visit this Frankenstein in person, he still held back.

Everyone has his own secrets. Since Zhang Peng is willing to keep a low profile, let him keep a low profile.

It is impossible for him to rashly investigate a rising scientific star because of some doubts in his heart.

At least the room-temperature superconductivity invented by Zhang Peng is indeed very, very beneficial to mankind. Maybe he just patted his head and had a flash of inspiration?

Didn't Newton discover gravity with a flash of inspiration?

Who knows about scientific matters? Maybe it's just such a coincidence and luck...

The sage mode is over, and a new story begins.
