From a university student to a chief academician

Chapter 280 Nine Hardest Materials
Kyoto, Satellite Navigation System Management Office!

After hanging up the phone, Director Yang walked back to the conference room, sat down in the first seat, and looked at the noisy crowd in the conference room, shaking his head helplessly.

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

This situation is very common, and the satellite is damaged by meteorites, rays, black holes or other things in the universe.

In the past, they launched fewer satellites for long-distance voyages, so the loss was not large.

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

Therefore, more and more satellites are being launched now.

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

So, they are discussing whether there is a material that can increase the defense of satellites.

Even if it is hit by a meteorite, it will not be damaged in any way.

A middle-aged man with thick glasses, half-white hair, and wrinkled face said: "Don't the Graphene Research Center have carbon nanotubes? These things are so strong that even space elevators can be manufactured. And this material is very flexible, just suitable for making satellites."

Many people nodded slightly when they heard this. If carbon nanotubes are used to make satellites, it is indeed very suitable.

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

Any meteorite hits it, the satellite is fine, but the meteorite turns into fragments.

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

At that speed, anything would be crashed.

However, in the entire universe, meteorites with such a speed rarely exist.

Therefore, meteorites with such a speed can be ignored.

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

"No!" A middle-aged man with a square face shook his head slightly and said, "The supply of carbon nanotubes produced by the Graphene Research Center is in short supply. 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."

"Think about how we make satellites. It's not a few kilograms of carbon nanotubes, it takes tons of carbon nanotubes."

The several tons here does not mean that the satellite has several tons, but that there must be material damage in the process of manufacturing the satellite.

Therefore, the weight of the materials used to manufacture satellites is far greater than that of the satellite itself.

Besides, satellites weighing several tons are not suitable for going to the sky. The first element of satellites is to ensure performance and light weight, the lighter the better.

"Under the current conditions, it is impossible for the Graphene Research Center to provide us with several tons of carbon nanotubes."

"Yeah!" Everyone nodded slightly when they heard this.

Another person asked: "Where is carbyne sulfide?"

Carbyne sulfide is the hardest of all materials discovered so far.

It is harder than graphene material, its density is more than 200 times that of water, about forty times that of diamond, and more than twice the tensile strength of graphene.

Therefore, it is harder than carbon nanotubes.

Carbyne sulfide is composed of methine free radicals, and its chemical formula is called CH-, so it is also called monohydrogen.

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

Because of the unstable internal structure, although the hardness of carbynylsulfide is higher than that of carbon nanotubes, it is not as good as carbon nanotubes in terms of compression resistance.

Also, it is easily vaporized, 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 easily oxidized in space."

"At that time, the satellites we manufacture will be very prone to failure."

"Satellites made with carbyne sulfide are equivalent to throwing money away for nothing. I strongly disapprove of using carbyne sulfide to make satellites."

"We should find a material that produces energy, has higher stiffness, is lighter, and is structurally stable."

Many people nodded slightly, agreeing with this point of view.

Someone said irritably: "Carbon nanotubes, fullerenes, graphene, and carbyne sulfide are already the hardest materials we can think of, and they are also very light."

They thought of many materials, Darwin's spider silk, osmium, carbon composites, wurtzite boron nitride, hexagonal diamond, graphene, carbyne sulfide, fullerenes, and carbon nanotubes.

These are the nine hardest materials ever discovered.

Darwin's spider silk is a kind of silk produced by Darwin's spider. It is the hardest and lightest spider silk among all spider silks.

After 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 a certain gap even compared with osmium.

Osmium is a very dense, high ignition material commonly used in fountain pen nibs and bearings in timepieces.

Wurtzite boron nitride is a crystal composed of many atoms or compounds.

Boron and nitrogen, the fifth and seventh elements on the periodic table, are extremely extreme, but also extremely hard materials.

Formed during volcanic eruptions, the material is 18% harder than diamond.

Osmium and wurtzite boron nitride are two materials, although they are very hard, they are heavy.

In addition, carbyne sulfide is structurally unstable.

Therefore, in the end, everyone still focuses on carbon materials.

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

They want to find a material that is more balanced in quality and hardness among carbon elements.

After discussing for a long time, they didn't discuss what material to use.

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

They can wait, but they have heard that carbon nanotubes will not be free 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 compound carbynylsulfide been successfully developed?"

Carbyne sulfide is the material with the highest hardness in the world, but it has the disadvantage of being easily oxidized because of its unstable internal structure.

Therefore, it cannot be used in many fields.

However, many scientists around the world are working on research and development to remove the disadvantages of carbyne sulfide and create a composite carbyne sulfide material.

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

Director Yang shook his head slightly and said, "It hasn't succeeded yet!"

Many people let out a long sigh of regret.

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

"Is there any prospect of his research and development?"

Director Yang shook his head slightly: "I talked to him on the phone two days ago, but I still haven't found anything."

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

"Director!" Someone said in distress: "The higher-ups are pressing hard, and we can't find suitable materials. Why don't you talk to the higher-ups and let the higher-ups relax for a while!"

Director Yang glanced at the speaker, and said expressionlessly: "We can wait, but can other countries wait for us?"

"All countries in the world are occupying holes in the universe. If we don't catch up, we will easily fall behind."

Everyone sighed in their hearts, why didn't they know such a truth, but they really couldn't find suitable materials now!
How to make a satellite that can block meteorites without suitable materials.

Of course, they are not lacking at the technical level.

They also thought about installing some technology on the satellite, which can predict the trajectory of the meteorite in advance, so as to avoid the meteorite.

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

Therefore, materials are very important to a satellite, even more important than technology.

Director Yang saw that everyone didn't have a good idea for a while, and he was also very helpless.

Director Yang said: "Since everyone has no good ideas, let's stop here for today's meeting. Go back and think about what other materials are suitable."

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

"We'll have another meeting after we find the right material in a few days."

Director Yang glanced at his watch and said, "It's past twelve o'clock in the evening, everyone, go back and rest!"

"Yeah!" Everyone nodded, that's all they could do, there was no way for them to sit still.

After speaking, everyone left the meeting room.

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

"By the way, in the middle of the meeting, Ye Fei called me and said that there is a new material to make a dark matter detector, and he wants to use the dark matter detector to travel through the universe in an instant."

Thinking of this, Director Yang felt amused.

How could it be possible to travel through the universe in an instant with the technology on earth.

Even if it is possible to realize the instantaneous shuttle of the universe, the material of the dark matter detector must be very strong.

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

Director Yang shook his head slightly in his heart: "How could such a material exist? At least according to the materials that have been discovered on the earth so far, no such material has appeared yet."

"If such material really appeared, we would not be so distressed at today's meeting."

"It is impossible for Ye Fei to let the dark matter detector realize the instantaneous shuttle of the universe."

After a while, Director Yang entered the office.

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

There is a black desktop computer and some paper and pens on the desk.

A set of quilts and pillows lay on the sofa.

Director Yang usually works too late, so he doesn't go home and just lies on the sofa overnight.

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

After a while, Director Yang put down his hands, opened his eyes, shook his head to wake himself up, and then put on his glasses again.

Then, he turned on the computer, ready to check the email 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, he pinched his right arm with his left hand.

"It hurts..." Director Yang said in surprise.

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

Immediately, he looked at the email and said anxiously: "Is this true?"

He was very uneasy, fearing that the materials and data Ye Fei sent him were fake.

According to the material data on the mail, this is the material their department has been looking for.

Moreover, the material is more perfect than they expected.

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

If the material cannot be mass-produced, 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 the phone again, and said, "It's past twelve o'clock now, Ye Fei must have fallen asleep, call him tomorrow!"

That night, Director Yang lay on the sofa without falling asleep, staring at the ceiling with his eyes open, feeling uneasy in his heart, praying that the material data provided by Ye Fei must not be fake, and mass production is still needed.

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

However, if Ye Fei didn't 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 is up to par, and if it can't be mass-produced, then they can't use the material either.

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

Ye Fei was lying on the bed sleeping, at this moment, 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 to touch the phone on the bedside table, then squinted his eyes to look at the phone, he didn't see who called him on WeChat , he connected the WeChat.

He said in a sleepy voice, "Hi!"

"Academician Ye!" Director Yang's voice sounded from the phone, "I'm very sorry to call you so early."

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

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

"Academician Ye, is the material data you sent me last night true? Do you have this 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 nervously: "Can it be mass-produced?"

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

Ye Fei is now much more awake and can talk to Director Yang freely.

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

In an instant, the glaring sunlight came in from the window, breaking the darkness in the room.

Immediately, Ye Fei opened the window, and fresh air rushed in.

There is a big mountain behind Ye Fei's house.

Ye Fei took a deep breath, and the refreshing air flowed through his nostrils. There was a lush green mountain in front of him, and he felt very refreshed.

"Director Yang, based on the material data I gave you, is it possible to manufacture a dark matter detector?"

Director Yang smiled and said, "Of course."

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

Director Yang still felt a little uneasy, and wanted to see this material with his own eyes.

"Yes!" Ye Fei said.

Director Yang couldn't wait to say: "Okay then, I'll book a ticket now and arrive in Jinling in the afternoon."

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

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

"Graphene Research Center?" Director Yang asked in surprise, "Is this a material developed by the Graphene Research Center?"

Director Yang was very puzzled. Some time ago, he asked Director Li of the Graphene Research Center 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, why, I asked you, but you said no, but Ye Fei told me in the end.

This made Director Yang feel that he was played by Director Li.

In fact, Director Li is not to blame for this, the main reason is that F60 graphene has not been approved by the above, so naturally we cannot tell others.

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

Ye Fei said: "Yes!"

Director Yang gritted his teeth fiercely in his heart, okay, it really is so, Director Li, please wait for me, I will settle accounts with you today.

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

After speaking, Director Yang hung up the phone.

Holding the phone, Ye Fei felt that something was wrong with Director Yang's last tone.

Ye Fei shook his head slightly and didn't think about it any more.

Ye Feixin said: "Since the dark matter detector can be manufactured, the next step is to develop how to make the dark matter detector made of F60 graphene realize the instant shuttle of the universe!"

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