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

Several other experts also came forward and touched it one after another.

The barrier outside the ice coffin is colorless and tasteless, but it is very strong. It feels like a wall.

In order to eliminate the possibility that the barrier band is a transparent solid, Zhang Mu and others have tried a series of means such as Sims instrument, liquid nitrogen, hydrofluoric acid, aqua regia and so on.

In half an hour.

Looking at the white gas of liquid nitrogen falling into the ground, Zhang Mu looked at each other with the other two chemical experts, and then nodded at the same time.

Then Zhang Mu said to Lu Chaoyang and Zeng Gucheng:

"Professor Lu, academician Zeng, according to the current situation, this barrier band is undoubtedly a gas wall - whether it is a pure molecular wall or a barrier region composed of micro nano crystals, in short, it can not be a solid in the macro field."

Lu Chaoyang nodded when he heard the speech.

Although he was a physicist, he also had a wide range of knowledge in chemistry, so he took Zhang Mu's idea without much effort:

"In addition, there must be no hydrogen bond and phosphate diester bond groups in this gas wall. I even suspect that there is no chemical bond in this compound."

Hearing the second half of Lu Chaoyang's words, Qian Yuhang, another chemical expert, couldn't help saying:

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

"Wait!"

Qian Yuhang was interrupted by Zhang Mu and Lu Chaoyang before he finished speaking.

I saw what the oldest and youngest in the expert group thought at the same time, and said a noun in one voice:

"Sodium helium!"

With the utterance of sodium helium, the whole secret room fell into a silence.

The silence of several experts and their assistants was due to a new idea or possible discovery.

Wei Fan and Zhang Yaqing are pure ABA.

In particular, Wei Fan, a straightforward man, even had a little doubt about his brain:

Obviously I understand every word they say. How can it be connected like a heavenly book???

The secret room was silent for about ten seconds. Then Zhang Mu suddenly looked at Lu Jie:

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

Lu Jie is also a top genius in terms of talent. He was selected into the 10000 person plan very early. He can be said to be a big guy.

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

"Yes, I'll start analyzing now!"

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

Lu Jie looked at it, his face suddenly flushed, and said in a loud voice:

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

Hearing this, Qian Yuhang subconsciously opened his mouth, but made no sound.

After a while, he sighed faintly:

"Is it really a helium compound, interference phenomenon, dimer helium..."

as everyone knows.

People are divided into three genders: men and women and Xiuji.

Matter has three states: gas, liquid and solid.

For example, water under normal pressure is gaseous steam above 100 ℃, liquid water at 0-100 ℃, and solidified into solid ice after cooling below 0 ℃.

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

However, nothing is absolute. Helium is an exception.

Even if the temperature is reduced to absolute zero - that is - 273.15 degrees below zero, helium under normal pressure cannot solidify into a solid, but can only remain in a liquid state.

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 the helium atom is too light and the quantum uncertainty is too strong.

Even at absolute zero, helium can maintain a certain movement, thus destroying the ordered solid structure.

However, in February 2017, a team led by Nankai University announced the achievement that helium can form the compound sodium helium (na2he), which was published in the journal Nature. (attached doi.org 10.1038s41467-018-03284-y)

The composition of sodium helium compound just like what Zhang Mu and Lu Chaoyang said, does not need any chemical bond.

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

He can be said to have only a structural effect, diluting 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.

According to this principle, Lu Chaoyang and Zhang Mu made a judgment:

A special reaction took place around the ice coffin, producing countless trace amounts of helium compound crystals - note that it is not sodium helium compound, but helium compound with similar principle.

There is no chemical bond in this compound, but the crystal cell structure forms a standard solid hexahedron, with the level of nano or even smaller.

It is the combination of these quasi gaseous particles that forms the gas wall.

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 exactly one of the abilities that a scientific researcher needs most.

Like Qian Yuhang and another chemical expert, they are real Chinese chemical authorities without a trace of water.

They didn't think of helium compounds before. Is it because they don't have enough knowledge?

This is obviously impossible.

It can only be said that their thinking sensitivity is not enough, and they will not think of the concept of sodium helium for a moment and a half - and their lack of sensitivity may be a natural barrier between domestic authorities and Nobel laureates.

In other words, Lu Chaoyang already has a necessary ability to be a top scholar in the world.

How many people can't envy it all their life

Then Zhang Mu continued to ask Lu Chaoyang:

"Professor Lu, there must be helium now, but the sodium ions in this region are obviously not enough to form sodium helium on the scale of gas wall.

So there should be another similar helium compound here. What do you think is the possibility? "

Lu Chaoyang frowned and thought for a while. Finally, he sighed a little discouraged and said:

"Professor Zhang, chemistry is not my major. I can think of sodium helium as my limit. Further down... I really can't think of it."

Zhang Mu smiled and patted him on the shoulder, then stretched out his hand and pointed to the ground:

"Think about it. Where is this?"

Lu Chaoyang was stunned and blurted out:

"Da Mo Jie... Ah, no, yangbei city."

"What do you say about yangbei city?"

"More than 50000 people, a finished City, and an iron mine... And so on?!"

Lu Chaoyang suddenly thought of something. A flash of lightning exploded in his mind:

"You mean... Iron ions?"

Zhang Mu continued to smile, nodded and corrected:

"To be exact, it should be ferrous ions. Although we can't prepare ferric helium locally, ferrous ions can also form cell structure.

The gas wall composed of iron helium micro crystals blocks us, and the energy comes from the solid surface energy. "

Solid surface energy is a parameter to quantify solid surface reactivity.

The simplest explanation of this concept is:

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

Therefore, the formation of crystals will inevitably lead to the increase of the total energy of the system, which is the surface energy.

The calculation method of surface energy is also very simple, which can be measured by IGC.

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

One button fool operation, simple flying.

How to say, Zhang Mu is worthy of being a top-notch big man. At present, the inference of gas wall is basically the most logical.

While Zhang Mu was talking, Chen Yue, the last chemical expert, suddenly interrupted:

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

The preparation pressure of sodium helium needs 3 million atmospheres of standard strength... Even if there are such conditions in the greater Mozambique boundary, it should not appear here, otherwise we would have been pressed into meat cakes. "

Zhang Mu nodded and admitted happily:

"This is really a difficult problem to explain. We can't analyze the internal situation of the ice coffin at the moment. I'm afraid it's a difficult problem to solve for a while."

"Didi -"

Just after Zhang Mu said these words, Lu Chaoyang's communicator suddenly rang.

Lu Chaoyang smiled apologetically at several people and turned on the communicator:

"It's academician Pan's call. Wait a minute, everyone. Maybe there's something going on in the state transmission laboratory."

Then Lu Chaoyang walked over with the communicator:

"Teacher pan, um, it's me... Um... What... Um... I see."

A few minutes later, Lu Chaoyang looked complex and returned to several people.

He thought it over 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 knows our current progress.

Academician pan just asked me about this... He has a guess about the energy to form ferrous helium. "

Zhang Mu was stunned when he heard the speech and was immediately overjoyed.

He didn't feel embarrassed when he was slapped in the face. It would be great if academician pan Jianwei could give an appropriate explanation:

"What is academician Pan's guess?"

Lu Chaoyang organized the language and said:

"Three million atmospheres of standard intensity, which is 30000 times the surface pressure of Venus.

This pressure already belongs to the pressure range of the high pressure level in the earth's core, and the instantaneous wind pressure level in the central area of the nuclear explosion of ordinary nuclear bombs is just this number.

This pressure, not to mention the practitioners of Yuanying realm, even if the realm of transforming God has some special means, it can resist for a few seconds at most.

If there is such pressure in the ice coffin, the cultivation of the girls in the ice coffin has exceeded the spirit, or the ice coffin is a magical material with more than all known compressive strength, or... There is no such pressure inside.

Academician pan thinks that the third situation is more likely, so he thinks whether this energy will come from

Vacuum zero energy? "
