The new task moved Li Mu's heart.

"This mission...... It's really challenging. ”

Direct synthesis of room-temperature superconductors......

This kind of creation, which exists only in the works of the human imagination, will now be realized in his hands......

No matter how you think about it, it's still a little incredible.

Of course, soon, he was relieved.

There's a brain computer in your head, and what could be more incredible?

Shaking his head, he didn't think much more.

"It's just that if superconductors at room temperature are really synthesized in reality......

Li Mu's heart suddenly floated.

If it is really synthesized at that time, it can only be synthesized at home, not abroad.

Even if it is really synthesized abroad, he must quickly destroy it, as well as all kinds of related materials.

After all, what does it mean to be a superconductor at room temperature?

Unlike the vast majority of people who only know a little bit because of the news some time ago, as a physicist and the author of "On Superconductivity", Li Mu can stand in front of countless people, pose with both hands on the accordion, and then say that no one knows superconductors better than him.

常温超导体一旦诞生，对于他来说，不仅可以帮助他来验证《论超导》的正确性，能够让他对维度力相关的理论有更加深刻的认识。

For the entire human society, the birth of room temperature superconductors can be called another industrial revolution.

From the use of steam engines in the first industrial revolution to the use of electricity in the second industrial revolution, both industrial revolutions originated from the further use of energy.

As for the so-called third revolution in the future, in fact, generally speaking, it will not be called the industrial revolution, but will be called the scientific and technological revolution, mainly around the development of various emerging technologies, such as the use of atomic energy, as well as computers, space technology and other aspects of technology, among which there is something related to energy is atomic energy, but for the time being, the development of atomic energy is not particularly prominent, after all, as we all know, there are still many problems in atomic energy technology.

In the future, the so-called fourth information revolution will have nothing to do with energy - of course, if you have to say, the information revolution can also be regarded as a more efficient use of energy, such as the use of information technology to control industrial equipment, so as to achieve more accurate and efficient production than manual production.

But in any case, although these technologies in the future have brought great changes to human life and society, they have not changed the human mastery of more powerful new energy.

Even if the new energy is being developed now, it is only because human beings consider the environmental cost, and have to choose these inefficient new energy sources.

And now, the room temperature superconductor model that Li Mu has in his mind is a technology that can truly set off the industrial revolution again.

Electricity is the most convenient energy source to use among the current human discoveries, and it is conceivable that for a long time in the future, the use of electricity by human beings will not change, just like now, all kinds of new energy in the end into electric energy, such as those new energy vehicles or something.

For example, the extended-range car uses oil to generate electricity, converts it into electric energy, and then provides power to the car through an electric motor.

When all kinds of other energy sources are converted into electrical energy and when electrical energy is transported, there is an unavoidable defect, that is, the loss caused by resistance.

根据估计，全华国每年因为电阻带来的损耗高达三千多亿度，差不多相当于三个三峡发电站一整年的发电量，足够让川省用一年。

If the superconductor is replaced at room temperature, such losses can be saved and can be used in more places where there is a shortage of electricity.

Of course, at this time, some people may say that China's annual power generation is as high as more than 8 trillion kWh, and the loss is more than 300 billion kWh, accounting for less than 4 percent, which seems to be nothing.

But in fact, one thing that must not be ignored is that this low loss is built on the basis of China's world-leading high-voltage transmission lines, and such high-voltage transmission lines, in terms of the cost of construction and maintenance, are unimaginably high, for example, transformers, a transformer is tens of thousands, and all the transformers in the country add up to tens of millions, equivalent to trillions, not to mention that there are many people who die because of high voltage every year.

而一旦更换了常温超导体输电线路之后，就不存在这些问题了，高压输电线路直接变成正常的220v输电线路，直接输送到户，中间也不需要经过那些什么额外的仪器了，也再也不需要那些维护成本，变压器将会成为蒸汽机那样，被后世的学生们在历史书上认识，并且只会在博物馆见到的“老古董”，以此来让人类纪念曾经所经历过的一段时光。

In addition to the use of electric transportation, superconductors at room temperature have also played a role in many places.

All in all, once such a technology really appears in this world, it will inevitably get the attention of almost all countries.

Of course, that includes the five big hooligans on the planet.

However, Li Mu, as one of them, naturally knew that if the room temperature superconductor was really born from his hands, then the place of birth would naturally be his hometown.

He narrowed his eyes.

"It's been so long since I've been out, it's time to prepare for my return home."

As a wanderer, he still returns home after all.

Shaking his head, he didn't think much about it, no matter what, he still needed to make some preparations before returning home.

Now, let's study this room-temperature superconductor thoroughly in the computer in my mind.

Shifting his gaze to the metal in front of him again, Li Mu's heart moved, and then a magnet also appeared in front of him, and then his person also appeared in this simulated space, and then put this magnet and superconductor together.

The classical Meissner effect then arises, and the effect of quantum locking makes this room-temperature superconductor "locked" at a certain height very stably, and the distance between the two does not change as he keeps turning.

In this way, it can be basically determined that this is a superconductor, and Li Mu looked at the current set ambient temperature, which is 25 degrees Celsius.

Very standard laboratory room temperature values.

Therefore, the prefix of the superconductor in front of me can also be very clearly added to the word room temperature.

However, a superconductor at room temperature only means that the superconductor can reach a superconducting state at room temperature, but does not mean that its critical temperature is superconductivity.

In addition, there are some superconductors that have two critical temperatures, one upper limit and one lower limit, and exceeding the upper limit or lower than the lower limit will lead to the loss of superconductivity.

In addition, there is another key point, which is the size of the critical current and the size of the critical magnetic field.

The performance of a superconductor depends on these three critical values.

Therefore, Li Mu also needs to measure this superconductor.

"The system can't give me a whole one, although it's a superconductor at room temperature, but the critical value is so low that it can't be used......"

Li Mu's heart suddenly became suspicious.

According to the urine nature of the system, maybe it is really possible?

After all, you just say it's a room-temperature superconductor, right?

Suddenly, Li Mu was in a hurry, and he immediately began to test.

The first is a measurement of the upper limit of the critical temperature.

This measurement is very convenient, he only needs to adjust the temperature in the simulated space, so soon Li Mu got a very pleasant result.

"The upper critical temperature is 106 degrees?"

Li Mu was quite surprised.

106 degrees means that even when operating at the temperature of evaporated water, the superconductor remains in a superconducting state without changing.

Even distilled water at 105 degrees is not enough.

In this way, the upper critical temperature, to a large extent, does not need to worry about the possible quench, unless it is really messed up, otherwise, with this kind of superconductor that can be soaked in boiling water with a layer of waterproof insulation on the outside, there is basically no need to worry about the possibility of quenching.

Of course, this is not over, there is also the lower critical temperature, and soon, Li Mu also measured it, and the lower critical temperature is -201 degrees Celsius, which is below the temperature of liquid nitrogen.

In other words, it can still maintain a superconducting state at the temperature of liquid nitrogen, so by definition, this room temperature superconductor can also be called a high-temperature superconductor.

However, unlike other high-temperature superconductors, the upper critical temperature of other high-temperature superconductors exceeds the temperature of liquid nitrogen, while the lower critical temperature is lower than the boiling point temperature of liquid nitrogen.

This is the magic of materials science.

Li Mu sighed, and then began the next two tests, the critical current density, and the critical magnetic field strength.

According to all the existing superconductors, regardless of the critical temperature, the best performance is the niobium-titanium alloy, whose critical current density reaches 10^9A per square meter, and the critical magnetic field is about 10.5T, and even 14T at 2K.

It is this excellent performance that makes niobium-titanium alloys the first choice for various superconductor applications, whether it is nuclear magnetic resonance, nuclear fusion experimental reactors, particle colliders, etc.

And now, the system rewards this room temperature superconductor, first of all, in the critical current density of 10^10A per square meter, which is ten times that of niobium titanium alloy!

And the critical magnetic field strength has reached an extremely high 31T!

Such a critical magnetic field strength would be enough to dominate the entire superconducting world.

"The critical temperature is -201 degrees Celsius to 106 degrees Celsius, the critical current density is 10^10A, and the critical magnetic field strength is 31T......"

Li Mu's eyes seemed to be able to peek out of their sockets.

Good guys, if you divide these superconductor materials according to the gacha game, niobium-titanium alloy is the kind that has excellent performance in R cards and is often used by players, while yttrium-barium copper oxygen is the kind of high-temperature superconductor that has very poor performance in SR cards and can only be used as a vase.

And now, this piece in his hand...... For the time being, it is called a copper-iron-niobium-zinc alloy superconductor, which is the noble SSR, and it is also the human rights card in the SSR.

God of God!

One hundred dusks!

"System, I was a little loud just now, I was wrong."

Realizing what kind of precious material this was, Li Mu's eyes immediately cleared, looked at this simulated space, and began to exert the spirit of craftsmanship.

After bowing deeply, Li Mu immediately refocused his gaze on the SSR superconductor in front of him.

"Give it a name before ......"

Li Mu pinched his chin and thought for a while, then finally clapped his hands and said, "Then let's call it LSC alloy." ”

L is Lee, and SC is SuperConductor.

Simple and easy to remember.

After determining the name of the LSC alloy, Li Mu's hand waved, and in an instant, the LSC alloy immediately became bigger in his eyes - but strictly speaking, it should be that he kept enlarging his gaze, so that he could see a more microscopic world.

And this is precisely in the simulation space, which is of great use for materials science research.

He can directly observe the material under the microscope without the use of a microscope, which is obviously much more convenient than the observation of the microscope.

In this way, Li Mu continued to zoom in and out, until finally, he saw a familiar picture - it was the image that can be seen when using STEM, that is, when observing the structure of materials with a scanning electron microscope.

Li Mu couldn't help but marvel.

Observing such a scene directly with "eyes" is far more impressive than taking an image with a microscope.

For Li Mu, this is the first time, and he can be sure that this scene will be unforgettable for him.

Still, apparently this was not enough for him to continue to amplify.

It wasn't until finally he could faintly see the "particles".

But at this point of amplification, the warning sound of the system sounds: "The current magnification has reached the limit of computing power, please consider whether to continue amplification carefully." ”

Hearing this warning, Li Mu did feel that his brain was already a little swollen.

Helpless, it seems that this is the only way.

He stopped zooming in and began to observe the microcosm in front of him.

He did see the particles.

Strictly speaking, it should be atomic.

The atom we know from textbooks seems to be a ball, but in fact the atom is only composed of the nucleus and electrons outside the nucleus.

The size of the nucleus is negligible, only 1 in a few billions, so he will definitely not be able to see the nucleus, and the electron is smaller than the nucleus, and he will definitely not be able to see the electron.

But what is the ball he sees now?

"Is this the e-cloud......"

Li Mu muttered.

Electrons will randomly appear anywhere outside the nucleus because they obey quantum effects, so because of this randomness, electrons teleport countless times in an instant, and thus an electron cloud is formed.

And now, Li Mu saw it "with his own eyes".

But alas, he can only see it in this simulated space, not in reality.

He didn't really see it in this space, but the computer in his mind made him see it.

Maybe......

The thing he saw was just a simulation of his mind computer according to his understanding?

It's like in the microcosm, there is no color, and the world he sees now is gray.

Li Mu shook his head, forget it, he should stop thinking about this problem.

The most important thing for him now is to determine the structure of the LCS alloy in this microscopic world.

So he gathered his attention and looked at the microcosm in front of him.

Then, he exclaimed.

"What is material characterization, this is called material characterization!"

In this microcosm, all the microscopic structures of this material are clearly visible in his eyes.

At this time, his confidence increased infinitely.

There is such a microcosm, materials science, will be in his grasp!
