Another world conquest manual

After Lu Chaoyang personally experienced the touch of the ice coffin barrier area and confirmed that there was no strong rebound or other characteristics.

Several other members of the expert group also stepped forward to touch and experience it.

The barrier outside the ice coffin is colorless and odorless but extremely strong, feeling like a wall.

In order to rule out the possibility that the barrier zone is some kind of transparent solid, Zhang Mu and others tried a series of methods such as SIMS instrument, liquid nitrogen, hydrofluoric acid, aqua regia and so on.

Half an hour later.

Looking at the white steaming liquid nitrogen falling onto the ground, Zhang Mu and the other two chemistry experts looked at each other, and then nodded in unison.

Then Zhang Mu said to Lu Chaoyang and Zeng Gucheng:

"Professor Lu, Academician Zeng, judging from the current situation, this barrier zone is undoubtedly a gas wall - whether it is a pure molecular wall or a barrier area composed of tiny nanoscale crystals, it cannot be a macroscopic area. solid."

Lu Chaoyang also nodded after hearing this.

Although he is a physicist, his knowledge of chemistry is also very broad, so he followed Zhang Mu's train of thought without much effort:

"In addition, there are definitely no hydrogen bonds or phosphodiester bonding groups in this gas wall. I even suspect that there are no chemical bonds in this compound at all."

Hearing the second half of Lu Chaoyang's words, another chemistry expert Qian Yuhang couldn't help but said:

"Professor Lu, how is this possible for compounds without chemical bonds? Only single atoms exist."

"etc!"

Before Qian Yuhang finished speaking, he was interrupted by Zhang Mu and Lu Chaoyang at the same time.

I saw that the oldest and youngest in the expert group, an old man and a young man, thought of something at the same time, and said a noun in unison:

"Sodium heliumide!"

As Nadium Helium spoke, the entire secret room suddenly fell into silence.

The silence displayed by several of the experts and their assistants was due to the discovery of a new idea or new possibility.

And Wei Fan and Zhang Yaqing are just Aba Aba.

Especially Wei Fan, this straightforward man even had some doubts about his own mind:

I obviously understand every word they say, but why do they sound like a heavenly book when they are put together? ? ?

The secret room was silent for about ten seconds, and then Zhang Mu suddenly looked at Lu Jie:

"Xiao Lu, quickly analyze whether there is helium in the area outside the ice coffin!"

To be able to become the assistant of a super boss like Zhang Mu, Lu Jie is also a top genius in terms of talent. He was selected into the Ten Thousand People Plan very early and can be said to be a promising candidate for a big boss.

Therefore, he quickly understood his teacher's thinking and said quickly:

"Understood, I'll start analyzing now!"

After about fourteen or five minutes, a line of results appeared on the instrument's operation screen.

Lu Jie looked at it, his face suddenly flushed, and he said loudly:

"Teacher, there is a large amount of helium around the ice coffin, and there is interference! That is, there are two helium atomic waves constantly superimposing!"

Hearing this, Qian Yuhang opened his mouth subconsciously, but did not make any sound.

After a while, he sighed quietly:

"Is it really helium compound, interference phenomenon, dimeric helium?"

As everyone knows.

People are divided into three genders: male and female Hideyoshi.

Matter has three states: gas, liquid, and solid.

For example, water at normal pressure is gaseous water vapor above 100°C, liquid water at 0-100°C, and solidifies into solid ice when the temperature drops below 0°C.

Most substances, like water, solidify as the temperature decreases.

But there are no absolutes, and helium is an exception.

Even if the temperature is lowered to absolute zero, which is -273.15 degrees below zero, helium at normal pressure cannot solidify into a solid and can only remain in a liquid state.

Because as an inert element, the attraction between helium and helium is very weak, and the binding force to maintain the solid state is weak.

The second is that helium atoms are too light and the quantum uncertainty is too strong.

Even at absolute zero, helium can maintain a certain motion that disrupts ordered solid-state structures.

But in February 2017, a team led by Nankai University announced the results that helium can form the compound sodium heliide (Na2He), and published it in the magazine "Nature". (Attached is doi.org/10.1038/s41467-018-03284-y)

The composition of the compound sodium heliide is just as Zhang Mu and Lu Chaoyang said, and it does not require any chemical bonds.

Because sodium in sodium heliide is an ion in an ionized state, its electrons are paired and filled in the crystal as color centers. In a sense, the crystal has a stabilizing effect similar to an ionic bond.

It can be said that He only has a structural effect and dilutes the repulsion between charges.

So to say that there is no chemical bond is to emphasize that He here is inert and has no chemical bond effect.

It was based on this principle that Lu Chaoyang and Zhang Mu made a judgment:

A special reaction occurred on the periphery of the ice coffin, producing countless trace amounts of heliumide crystals—note, not sodium heliide, but heliumide based on a similar principle.

There are no chemical bonds in this compound, but the unit cell structure forms a standard solid hexagon with a scale of nanometers or smaller.

It is the combination of these gas-like particles that forms this gas wall.

After hearing the results of Lu Jie's analysis, Zhang Mu glanced at Lu Chaoyang again.

At this point, it can basically be said that their guess is correct.

This young man is really amazing. He is obviously an expert in physics, but his chemical thinking is extremely sensitive.

Sensitive thinking is precisely one of the abilities a scientific researcher needs most.

Like Qian Yuhang and another chemistry expert, they are all real authorities in Chinese chemistry, without a trace of water mixed in.

They had not thought of helium compounds before. Could it be that they lacked knowledge?

This is obviously impossible.

It can only be said that their thinking sensitivity is not enough, and they did not think of the concept of sodium heliide for a while - and this part of the sensitivity they lack is likely to be the natural chasm between domestic authorities and Nobel Prize winners.

In other words, Lu Chaoyang already possesses a certain necessary ability of a top scholar in the world.

How many people would never envy this in their lifetime?

Then Zhang Mu continued to ask Lu Chaoyang:

"Professor Lu, helium is definitely available now, but the sodium ions in this area are obviously not enough to form gas wall-scale sodium heliide.

Therefore, what exists here should be another similar helium compound. What other possibilities do you think? "

Lu Chaoyang frowned and thought for a while, and finally sighed in frustration and said:

"Professor Zhang, chemistry is not my main major. Sodium heliumide is my limit. I really can't think of anything further."

Zhang Mu smiled and patted his shoulder, then pointed to the ground:

"Think about it carefully, where is this place?"

Lu Chaoyang was startled and blurted out:

"Da Mojie, no, it's Yangbei City."

"Then what do you think there is in Yangbei City?"

"A population of more than 50,000, a finished city, and an iron mine. Wait?!"

Lu Chaoyang suddenly thought of something, and a bolt of lightning exploded in his mind:

"You mean iron ions?"

Zhang Mu continued to smile, nodded, and corrected:

"To be precise, it should be ferrous ions. Although we are currently unable to prepare iron heliide locally, ferrous ions can also form a unit cell structure.

The gas wall composed of iron heliide microcrystals blocks our energy from the solid surface energy. "

Solid surface energy is a parameter that quantifies the reactivity of a solid surface.

The simplest explanation of this concept is:

The periodic lattice structure of a solid is the lowest-energy state that forms spontaneously, and the surface is equivalent to a two-dimensional defect—that is, it breaks the translational symmetry.

Therefore, the formation of crystals will inevitably cause the total energy of the system to increase, and this increased energy is the surface energy.

The calculation method of surface energy is also very simple and can be measured using IGC.

The principle is that the known phase passes through the stationary phase, FID detects the probe molecules, and then the mathematical model is used to calculate the relationship between the dispersion component or Lewis acid-base component and the surface coverage after multiple probe concentration experiments.

One-click fool-like operation, simple to fly.

How should I put it, Zhang Mu is indeed a top-notch guy, and his current inference on the gas wall can basically be said to be the most logical.

While Zhang Mu was speaking, Chen Yue, the last chemistry expert, suddenly interrupted:

"Academician Zhang, I agree with your analysis of the gas wall mechanism, but where does the energy that drives the combination of ferrous ions and helium come from?

The preparation pressure of sodium heliide requires 3 million standard atmospheric pressures. Even if there are areas with such conditions in the Great Mo Realm, they should not appear here, otherwise we would have been crushed into meat patties. "

Zhang Mu nodded and admitted happily:

"This is indeed a difficult problem to explain. We cannot analyze the internal situation of the ice coffin at the moment. This is probably a problem that will be difficult to solve in a while."

"Didi didi——"

Just after Zhang Mu finished speaking, the communicator on Lu Chaoyang suddenly rang.

Lu Chaoyang smiled apologetically at the people, turned on the communicator and took a look:

"This is Academician Pan. Please wait a moment. Maybe there is something going on at the Teleportation Laboratory."

Then Lu Chaoyang walked over with the communicator:

"Teacher Pan, um, it's me. um. what. um, um, I understand."

A few minutes later, Lu Chaoyang returned to several people with a complicated expression.

He thought about it and said to Zhang Mu and others:

"Academician Zhang, the situation in our secret room is transmitted to the headquarters in real time, so the headquarters also understands our current progress.

Academician Pan came to me just now to talk about this. He had a guess about the energy required to form ferrous helium. "

Zhang Mu was startled when he heard this, and then he was overjoyed.

He didn't feel embarrassed about being slapped in the face. It would be great if Academician Pan Jianwei could give a suitable explanation:

"What is Academician Pan's guess?"

Lu Chaoyang organized his language and said:

"Three million standard atmospheric pressures, which is 30,000 times the pressure on the surface of Venus.

This kind of pressure already belongs to the pressure range of the high pressure level in the earth's core. The instantaneous wind pressure level in the center area of ​​​​the nuclear explosion of an ordinary nuclear bomb is only this number.

This kind of pressure, let alone the practitioners in the Nascent Soul Realm, even if they have some special means in the God Transformation Realm, they can only resist it for a few seconds at most.

If there is such pressure inside the ice coffin, then either the little girl in the ice coffin has already surpassed the spirit of transformation, or the ice coffin is a magical level material that exceeds all known compressive strength, or there is no such pressure inside. kind of pressure.

Academician Pan believes that the third situation is more likely, so he wonders whether this energy will come from.

Vacuum zero point energy? "
