Kyoto, Satellite Navigation System Management Office!

Director Yang hung up the phone and walked back to the conference room, sat down in the first seat, and then looked at the noisy people in the conference room, and shook his head helplessly.

Recently, one of their satellites launched into outer space was damaged by a meteorite impact.

It is not uncommon for satellites to be damaged by meteorites, rays, black holes, or other things in space.

Previously, they launched fewer satellites for long voyages, so the losses were not significant.

But with the development of science and technology, human beings are more eager to explore outer space.

As a result, more and more satellites are now being launched.

But there are too many unknowns in the universe, and many unknowns have caused great damage to satellites.

So, they're talking about whether there's a material that would increase the satellite's defenses.

Even if it is hit by a meteorite, there will be no damage.

A middle-aged man wearing thick glasses, half-white hair, and a wrinkled face: "Isn't there carbon nanotubes in the graphene research center, this thing is very strong, even a space elevator can be manufactured, and this material is very flexible, just suitable for making satellites." ”

Many people nodded slightly when they heard this, and it was indeed very appropriate to make satellites from carbon nanotubes.

Satellites made of carbon nanotubes are not afraid of meteorite impacts.

Any meteorite hits it, the satellite is fine, but the meteorite is reduced to fragments.

Unless the meteorite hits at a speed of 0.1 light-years per hour.

At such speeds, anything can be knocked out.

However, meteorites of this speed are rarely present in the entire universe.

Therefore, meteorites of such a speed can be disregarded.

Therefore, it is very suitable to make satellites from carbon nanotubes.

"No way!" A square-faced middle-aged man shook his head slightly and said: "The carbon nanotubes produced by the Graphene Research Center are in short supply, and how many units in the country need to use carbon nanotubes!" ”

"Although the production capacity of carbon nanotubes is increasing year by year, there are still many units in the country that cannot use carbon nanotubes."

"If you think about us making satellites, it's not a few thousand pounds of carbon nanotubes, it takes a few tons of carbon nanotubes."

A few tons here, not to say how many tons there are satellites, but there will be material damage in the process of manufacturing satellites.

Therefore, the weight of the materials used to make the satellite is much greater than that of the satellite itself.

Besides, a satellite of several tons is not suitable for the sky, and the first element of the satellite is to ensure the performance of the premise, the lighter the weight, the better.

"Under the current conditions, it is impossible for the graphene research center to provide us with a few tons of carbon nanotubes."

"Hmm!" When everyone heard this, they also nodded slightly.

Another humane: "What about caryne sulfide?" ”

Carboxyne sulfide is the hardest of all the materials found so far.

It is harder than graphene materials, more than 200 times denser than water, about 40 times that of diamond, and more than twice the tensile strength of graphene.

As a result, it is harder than carbon nanotubes.

Caryne sulfide is composed of hypomethyl radicals, and is chemically called CH-, so it is also called one carbide and one hydrogen.

It is a very unstable gas or free radical containing only one carbon atom and one hydrogen atom, also known as methyl inyl group.

Because of the unstable internal structure, although the hardness of carboxylene sulfide is higher than that of carbon nanotubes, it is inferior to carbon nanotubes in terms of compressive resistance.

In addition, it is highly susceptible to vaporization, so its performance is not as good as that of carbon nanotubes.

Someone retorted: "This material is not suitable either, the internal structure of the material is too unstable, and it is very easy to be oxidized in space." ”

"When the time comes, the satellites we make will be very prone to failure."

"Satellites made with carboxylene sulfide are equivalent to throwing money out of the water, and I strongly disapprove of making satellites with carboxylene sulfide."

"We should find a material that has high energy yield, high hardness, light weight, and stable structure."

Many nodded slightly, agreeing.

Someone said irritably: "Carbon nanotubes, fullerene, graphene, carboxyne sulfide, this is already the hardest material we think of, and the weight is also very light." ”

They thought of a variety of materials, Darwinian spider silk, osmium, carbon composites, wurtzite-type boron nitride, hexagonal diamond, graphene, carboxylene sulfide, fullerenes and carbon nanotubes.

These are the nine hardest materials found so far.

Darwinian spider silk is a type of silk called the Darwinian spider, which is the hardest and lightest of all spider silks.

As a result of scientific research, humans can artificially produce pseudo-Darwinian spider silk.

Of course, in terms of hardness, not to mention compared with carbon materials, there is even a certain gap compared with osmium.

Osmium is a material with a very high density and high ignition point, and is commonly used in the bearings of fountain pen nibs and horological instruments.

Wurtzite-type boron nitride is a constituent crystal formed by the combination of many atoms or compounds.

Boron and nitrogen are the fifth and seventh positions on the periodic table, respectively, and are extremely extreme in form, but also extremely hard.

The material was formed during volcanic eruptions and is 18% harder than diamonds.

Osmium and wurtzite-type boron nitride are two materials that are very hard but heavy.

In addition, the carbon alkyne sulfide structure is unstable.

So, in the end, everyone is still looking at carbon.

Only the carbon element has the most stable structure, high hardness, and okay quality.

They wanted to find a material with a balance of mass and hardness in carbon.

After discussing for a long time, they didn't come up with what materials to use.

Many people sighed deeply in their hearts: "Although carbon nanotubes meet the requirements, the mass production is too low now, and the supply exceeds demand, so we can only find materials from other directions." ”

They could have waited, but they had heard that it would not be possible to achieve carbon nanotube freedom for at least five years.

They can't afford to wait five years.

"But what other materials meet the requirements!"

Someone looked at Director Yang and asked, "Director, has Academician Pang's composite carboxylene sulfide been successfully developed?" ”

Caryne sulfide is the hardest material in the world, but it is easily oxidized due to its unstable internal structure.

As a result, it is not available in many areas.

However, many scientists around the world are developing to remove the shortcomings of carboxylene sulfide and create a composite carboxylene sulfide material.

Academician Pang of Xia Guo is a leader in the research and development of this material.

Director Yang shook his head slightly and said, "It's not successful yet!" ”

Many people sighed with regret in their hearts.

If the internal structure of carboxyne sulfide is stable, then it will be a very ideal aerospace material.

"Is his R&D eyebrow-eyed?"

Director Yang shook his head slightly: "I talked to him on the phone two days ago, and I still haven't seen an eyebrow. ”

Everyone sighed with regret in their hearts, if they had eyebrows, they could wait, but they didn't even have eyebrows, which made them very desperate.

"Director!" Someone said distressedly: "The above is urgent, and we can't find the right materials, or you can talk to the above and let the above relax some time!" ”

Director Yang glanced at the person who spoke, and said expressionlessly: "We can wait, can other countries wait for us?" ”

"All countries in the world occupy a hole in the universe, and if we don't catch up, it will be very easy to fall behind."

Everyone sighed in their hearts, why don't they know such a truth, but they really can't find suitable materials now!

Without the right materials, how can you make a satellite that can block meteorites.

Of course, there is no shortage of technical aspects.

They also thought about installing some technology on satellites to predict the trajectory of meteorites in advance and avoid meteorites.

However, in the universe, there are not only meteorites, but also many attacks that cannot be seen.

Therefore, materials are very important for a satellite, it is more important than technology.

Director Yang saw that everyone had no good ideas for a while, and he was also very helpless in his heart.

Director Yang said: "Since everyone has no good ideas, let's stop today's meeting, and you should also go back and think about what other materials are suitable." ”

"I will also contact some materials scientists at home and abroad, as well as materials research institutes, to see what good materials are available."

"In a few days, when we find the right materials, we'll have a meeting."

Director Yang glanced at his watch and said, "It's more than twelve o'clock in the evening, let's go back and rest!" ”

"Hmm!" Everyone nodded, and that was the only way, and now they couldn't do anything about it.

With that, everyone left the conference room.

Director Yang walked slowly towards the office, thinking about what materials are suitable for satellite manufacturing.

"By the way, halfway through the meeting, Ye Fei called me and said that there was a new material made into a dark matter detector, and he also wanted the dark matter detector to travel through the universe instantaneously."

Thinking of this, Director Yang felt funny.

How is it possible to achieve instant travel through the universe with the technology of the earth.

Even if the universe can be instantaneously shuttled, the materials of the dark matter detector must be very strong.

It is several times stronger than the material they discussed at today's meeting, not only to withstand the impact of meteorites, but also to withstand the engulfment of black holes and the corrosion of rays.

Director Yang shook his head slightly in his heart: "How can such a material exist?" At least with the materials that have been found on Earth, there is no such material. ”

"If such material had appeared, we wouldn't have been so distressed at today's meeting."

"Ye has to let the dark matter probe realize the instantaneous shuttle of the universe, it is impossible to achieve it."

A moment later, Director Yang entered the office.

Director Yang's office is small, with a desk, three bookcases full of books, and a sofa.

On the desk was a black desktop computer and some pen and paper.

On the sofa is a set of quilts and pillows.

Usually, Director Yang works too late, so he doesn't go home and just lies on the sofa for a night.

Director Yang sat down at the desk, took off the glasses on his nose, put them on the table, then closed his eyes, pinched the bridge of his nose between his eyes with his fingers, and the depression in his heart slowly dissipated a little with this action.

After a while, Director Yang put down his hand, opened his eyes, shook his head to sober himself up, and then put his glasses back on.

Then, he turned on the computer and prepared to check the email that Ye Fei sent him.

Soon, he opened the email.

In less than a minute, his eyes widened in surprise, and his lips trembled: "This ......"

Then, with his left hand, he pinched his right arm.

"It's painful......," Director Yang said in surprise.

"High hardness, light weight, high stability!" Director Yang said excitedly: "This is the most perfect material, there is no more perfect material than it." ”

Immediately, he looked at the email and said nervously, "Is this true?" ”

He was very uneasy in his heart, afraid that the material data sent to him by Ye Fei was fake.

If you look at the material data on the email, this is the material that their department has been looking for.

Moreover, it was even more perfect than they had expected.

In addition to the accuracy of the material data, there is also whether the material can be mass-produced.

If the material cannot be mass-produced, then it cannot be used to make satellites.

He took out his mobile phone from his pocket, found Ye Fei's WeChat, and wanted to call him.

Then, he put down his phone again and said, "It's past twelve o'clock now, Ye Fei must be asleep, call him tomorrow!" ”

This night, Director Yang lay on the sofa and didn't fall asleep, looking at the ceiling with his eyes open, feeling uneasy in his heart, praying that the material data provided by Ye Fei would not be fake, but also energy.

Of course, reason told him that it should not be fake.

However, if Ye Fei did not admit it personally, then there is a certain probability that it is fake.

Therefore, he is more worried about whether it can be mass-produced.

The quality of the material meets the requirements, and if mass production is not possible, then they will not be able to use the material.

The next day, early in the morning, at six o'clock in the morning!

Ye Fei was lying on the bed and sleeping, and at this time, the mobile phone on the bedside table next to him suddenly rang.

"Ding Lingling ......"

After the phone rang for a while, Ye Fei opened his eyes in a daze, then closed them again, reached out and touched the mobile phone on the bedside table, and then looked at the mobile phone with half-squinted eyes, he didn't see who called his WeChat, so he connected the WeChat.

His sleepy voice said, "Hey! ”

"Academician Ye!" Director Yang's voice rang from his mobile phone and said, "I'm sorry to call you so early." ”

Although Director Yang didn't sleep all night, he was very energetic at the moment.

"Hmm...... It's Director Yang! Ye Fei tried hard to sober himself up and said, "Is there something wrong?" ”

"Academician Ye, is the material data you sent to me last night true? Do you have the material now? ”

Ye Fei said: "It's true, the materials are in my hands." ”

Director Yang's eyes lit up when he heard this, and then he said very worriedly: "Can it be mass-produced?" ”

"Yes, the production principle is somewhat similar to that of carbon nanotubes."

Ye Fei is much more sober at this moment, and he can talk to Director Yang freely.

Ye Fei took his mobile phone and lifted the quilt, got up from the bed, and then went to open the curtains.

In an instant, the harsh sunlight shone in through the window, breaking through the darkness of the house.

Immediately, Ye Fei opened the window, and the fresh air came to his face.

Behind Ye Fei's house is a big mountain.

Ye Fei took a deep breath, there was refreshing air flowing between his noses, and there was a green mountain in front of him, and his whole mood was very comfortable.

"Director Yang, according to the material data I gave you, can you make a dark matter detector?"

Director Yang smiled: "Of course you can." ”

"But, Academician Ye, I want to see this material with my own eyes."

Director Yang is still a little worried and wants to see this material with his own eyes.

"Yes!" Ye Feidao.

Director Yang couldn't wait to say, "Okay, I'll book a plane ticket now and go to Jinling in the afternoon." ”

Ye Fei stopped: "You don't come to Jinling, you can go directly to the Graphene Research Center and you can see that there is F60 graphene there." ”

"F60 graphene is the name of the material in the email I sent you."

"Graphene Research Center?" Director Yang was surprised: "Is this the material developed by the Graphene Research Center?" ”

Director Yang was very puzzled, and he asked Director Li of the Graphene Research Center some time ago if he had materials suitable for making satellites.

But Director Li told him no.

However, now Ye Fei told him that F60 graphene was developed by the Graphene Research Center.

This made Director Yang a little angry in his heart, what's the matter, I asked you, but you said no, but in the end, Ye Fei told me.

This made Director Yang feel that he was being tricked by Director Li.

Actually, this is not to blame Director Li, the main reason is that F60 graphene has not been approved by the above, so naturally it cannot be told to others.

And Ye Fei is the discoverer of F60 graphene, and Ye Fei wants to use it in advance, so it is naturally possible.

Ye Fei said: "Yes! ”

Director Yang gritted his teeth in his heart, okay, sure enough, Director Li, you wait for me, Lao Tzu is going to settle accounts with you today.

Director Yang said: "Academician Ye, thank you very much for telling me this news, let's talk later." ”

After speaking, Director Yang hung up the phone.

Ye Fei held the mobile phone, feeling that Director Yang's final tone seemed to be a little wrong.

Ye Fei shook his head slightly, and didn't think much about it.

Ye Feixin said: "Since we can make a dark matter detector, then we will develop how to make a dark matter detector made by F60 graphene to realize instant shuttle in the universe!" ”

"Even with the experience of instantaneous information transmission, it is very difficult to study this problem."
