The Red Era, the Opening University Speech

Chapter 214: The pinnacle of domestic applied physics

Except for the aunties in the cafeteria, everyone in the Semiconductor Research Institute is working around the clock every day because there are so many topics that need to be researched.

The development of Type 02 computers, the design of mass production of communication chips, the upgrade of electronic watch chips, the upgrade of distributed projection lithography machines, and the integrated circuitization of black and white televisions and radios.

Add to that the huge amount of manpower invested in game development, and everyone has at least three jobs.

Hiring people can solve the problem, but the problem is that the semiconductor research institute is so small that we can’t hire many more people.

After hearing Wu Youxiang's answer, Li Mu thought for a moment and said, "Director Wu, I don't think this is a solution. Why don't you apply for me to donate two laboratory buildings to our semiconductor research institute?"

"You can expand, but there's no need to donate the building. The country will support it." Wu Youxiang and Wang Shoujue were both at a loss for words.

They knew that Li Mu had made so many contributions to semiconductor industry products, and the country must have given him a lot of subsidies.

But no matter how rich you are, you can't help spending it like this.

Li Mu smiled and said:
"It's okay. I'm just worried about how to spend the money."

"You don't have to say that I paid for this. Just say it was a grant from the state."

"If we can save a little money here, many other research projects in the country will have more research funding."

The Semiconductor Research Institute is rich because it has industrial support and is also a key training location for the country.

But other research institutes are not that wealthy. Let alone building two laboratory buildings, even their equipment are still discarded by the big brother.

For example, the Radar Research Institute. Li Mu had been to their laboratory and the equipment there looked older than he was.

"I can't decide on this matter. You should discuss it with President Guo." Wu Youxiang shook his head like a rattle, with a look of rejection on his face.

Seeing this, Li Mu did not insist.

It would indeed be more appropriate to give it to Guo Mo, so that he can use the money in his hands on Steel Blade.

He only needs to keep a small portion to cover his and his family's daily expenses.

……

The next day, Li Mu took a day off.

Wash up and finish exercising.

In the study, I first wrote a research and development plan for the computer simulation platform, and then read some information on magnetohydrodynamics.

It was almost noon, so he went to the Semiconductor Research Institute for lunch, confirmed the progress of each research group, and then returned home.

Wu Youxiang has already reported this to his superiors, but it will still take a lot of time whether they send someone from the Institute of Computing Technology or find someone on their side.

Therefore, it will take some time to establish a computer simulation platform.

After returning to the special building and thinking for a while, he came to the door of Master Qian Wu’s house.

The two families were very close, and Jiang Ying would come to visit from time to time, and they had become very familiar with each other.

I knocked on the door, and soon I heard footsteps from inside.

Jiang Ying opened the door, saw that it was him, and enthusiastically brought him into the house, then went to call Master Qian Wu from the study.

Teacher Qian Wu was also very happy to see Li Mu coming, and he tested his recent progress in studying applied physics.

As he was talking, he suddenly said with emotion: "I heard that Emperor M has developed a ferrofluid, which helped them solve the problem of engine combustion stability for the moon landing."

"Our country's technology in all aspects is indeed far behind theirs!"

He was speaking out of inspiration, but it made Li Mu's heart move. He showed great interest and asked, "Teacher, is this ferrofluid difficult to make?"

"It's difficult. There is a sentence in the media report of M Emperor that 'magnetite is placed in an organic phase containing oleic acid for a long time and crushed to finally prepare a stable magnetic fluid'. I don't know how much time, manpower and material resources it will take us to make a breakthrough." Master Qian Wu said.

Li Mu asked again:
"I don't think it's difficult. I've learned about magnetic fluids. They are mainly composed of magnetic particles, carrier fluid and surfactants."

"Simply put, it is a special material formed by nanomagnetic particles dispersed in a liquid medium."

"In fact, I have recently learned some relevant knowledge, and I want to see if I can be of some help in the research of atomic submarines."

"Oh, you have studied it. Tell me about it soon." Master Qian Wu's eyes lit up and he asked curiously.

He naturally didn't think that Li Mu would be able to achieve any results in the applied research of magnetohydrodynamics so quickly. Even if he was a genius, it was a bit unrealistic.

But it's a good thing to have ideas. If he participates in it and works together, maybe he can really come up with it.

Li Mu opened the chat page, pondered for a moment, sorted it out, and then said:
"Traditional submarines use propellers for propulsion, so their mechanical structure is relatively complex and they generate a lot of noise when moving forward, but magnetic fluid can overcome this shortcoming."

“Using magnetic fluid technology, noisy mechanical structures such as propellers, power transmission devices, gears, etc. can be almost completely eliminated.”

"Technically speaking, its principle is to generate a strong magnetic field in the power area, using the electromagnetic Lorentz force and the conductive properties of seawater to eject seawater, thereby generating a huge reaction force to propel the submarine forward."

"My idea is to develop a propeller that creates a magnetic field in the channel where the ship passes through the seawater, generates electromagnetic force on the conductive seawater, and then makes the seawater flow at high speed in the channel toward the tail of the ship, thereby generating thrust."

……

At the beginning, Master Qian Wu was smiling as he listened, but his expression became more serious as time went on, and a hint of surprise appeared in his eyes.

Having this level of understanding of the application of magnetohydrodynamics in nuclear submarines is not as simple as Li Mu said, that it can be achieved through some study.

After Li Mu finished speaking, Master Qian thought for a moment and asked, "What do you think is the biggest problem if we want to develop a magnetohydrodynamic thruster?"

After saying this, he couldn't help but be stunned. Unconsciously, his tone became the same as when he usually discussed research with Zhao Jiuzhang, Guo Huai and others.

But how is this possible? Li Mu has only studied applied physics for a short time. Can he really achieve results in the application of magnetohydrodynamics?
In his expectant gaze, Li Mu smiled and said:
"I think there are three problems: one is the acquisition of high-performance materials, one is the improvement of energy conversion efficiency, and the last one is the integration and optimization of the propulsion system."

“I haven’t thought of solutions for the last two yet, but I do have some immature ideas about high-performance materials.”

"I think that rare earth elements can be added to the magnetic fluid. The special electronic structure of rare earth elements can theoretically improve the electromagnetic properties of the magnetic fluid and increase its magnetic permeability and saturation magnetization intensity."

"At the same time, rare earth elements can also affect the Curie temperature of the magnetic fluid, allowing it to maintain its magnetic properties at different temperatures."

After hearing this, Master Qian Wu could no longer conceal the shock in his eyes.

Adding rare earth elements, yes, that's indeed possible.

"Very good idea, your idea is very good!" Master Qian Wu praised generously. If Li Mu's idea can be realized, it will have a huge impact on Xiaguo's research on atomic submarines.

After thinking for a while, he stood up and said directly: "Don't go anywhere this afternoon, just stay in school. I will contact someone now, and we can discuss your idea in detail."

As he spoke, he walked out impatiently. Li Mu called out to him several times but he didn't even turn back, which made him laugh and cry.

But it’s normal to think about it.

The advantages of magnetohydrodynamic thrusters over traditional thrusters are huge.

If the research can be successful, even if the weapons and equipment are a little backward, we can still defeat the warships and submarines of the M Empire at sea!
……

Master Qian Wu acted quickly.

In the afternoon, he brought seven or eight professors to the University of Science and Technology and went straight to Li Mu's dormitory.

After calling Li Mu out, he went directly to the conference room of USTC.

The group was led by Master Qian Wu, and the experts and professors following behind them looked familiar at first glance. Looking further, they were all famous scholars in the field of physics. They walked hurriedly across the campus, causing quite a stir among the students.

……

After arriving at the conference room, Master Qian Wu first introduced the people he invited to Li Mu: "This is the director of the Institute of Atomic Energy, Peng Shilu, and the deputy director Jiang Nanying. This is an expert in magnetohydrodynamics and the current deputy director of the Department of Mechanics at Kyoto Aeronautical College, Lu Shijia..."

There are seven or eight of them, all of whom are big names in the physics community.

At the very least they are at the authoritative expert level.

This shows that the teacher has a terrifying appeal. Every gathering of these people present is a pinnacle debate in the field of applied physics in China.

After Master Qian Wu finished his introduction, Li Mu quickly greeted him, bowed and said, "Hello, seniors. I am Master Qian Wu's student, Li Mu."

"Your introduction is too modest." Teacher Qian Wu laughed and said, "This student of mine is really amazing. He serves as a consultant in six units including the Semiconductor Research Institute, the Computing Technology Research Institute, and the Agricultural Research Institute. He is more capable than a teacher like me."

Li Mu was ashamed: "Teacher, you are too kind. How can I compare with you?"

"Old Qian has a good student, Li Mu. I've heard of him as the king of inventions that the whole country was talking about some time ago." Peng Shilu, who was sitting below, said loudly.

This sentence made everyone laugh.

Lu Shijia, deputy director of the Department of Mechanics at Kyoto Aeronautical College, said with a smile: "He is indeed a great inventor. Not only can he invent civilian machinery such as air fryers and motorcycles, but he is also very accomplished in the development of atomic submarine propulsion systems. He is incredible!"

There was no teasing in her words, only admiration.

To be honest, everyone present, at Li Mu's age, even if they are also known as geniuses, their achievements are far inferior to his.

Such a young person with unlimited potential is a treasure to the scientific community of any country.

Li Mu pretended to smile bitterly and said:
"Seniors, please don't flatter me. It's just an idea. I didn't expect to get the teacher's affirmation."

"I have only just started my research in magnetohydrodynamics and I still have a lot to learn."

"As for inventing an atomic submarine propulsion system, that is not something that can be done in a short period of time."

When it comes to the development of magnetohydrodynamic propulsion, he is still prepared to be humble.

You should know that the world's first test ship using magnetohydrodynamic propulsion was the "Yamato 92" which was tested in 1 by Sanling Heavy Industries, which was in its early days.

As a military secret, atomic submarines should have been used earlier, but not more than 10 years ago.

At this point in time, Emperor M and Big Brother may not have started yet, and are basically in the theoretical exploration stage.

If he took it out too quickly, it would be a bit too outrageous.

"Okay, don't be so modest, Li Mu. First, explain your idea about adding rare earth elements to magnetic fluid again, and let's discuss it together." Master Qian Wu said.

Hearing this, everyone stopped teasing the younger generation and focused their eyes on Li Mu, full of anticipation.

Seeing this, Li Mu did not get nervous and quickly repeated his idea.

Finally, he also proposed a preliminary idea of ​​preparing water-based rare earth-loaded ferrite magnetic fluid by chemical co-precipitation:
"The reaction conditions, such as the pH value of the reactants, the ratio of Fe3+ to Fe2+, and the cation concentration, are controlled to prepare Fe3O4 nanoparticles with uniform particle size distribution and appropriate diameter. Furthermore, the saturation magnetization of the ferrite magnetic fluid is significantly improved by adding rare earth elements."

This method made everyone's eyes light up, and they couldn't help but nod:
"Yes, using this preparation method, there is indeed a great possibility to improve the performance of magnetic fluids."

"In this way, it is not impossible to make a magnetohydrodynamic thruster!"

"I think it is very likely. If a breakthrough is made in magnetic fluid technology, our country's atomic power research will take a big step forward and even surpass Emperor M and Big Brother!"

……

Originally they were planning to give some guidance to Li Mu, but unexpectedly after listening, they were more inspired.

"Well done. It can be seen that you have put a lot of effort into magnetofluid technology!" Master Qian Wu said with emotion while clapping.

Other experts and professors also gave generous applause and recognition.

Li Mu smiled modestly and said, "Teacher, I just had a flash of inspiration and came up with an idea. I don't know if it will work or not."

"Don't worry, your direction is basically correct. As long as you continue researching, you will definitely achieve results." Master Qian Wu affirmed.

In terms of applied physics, he is currently the most authoritative person in Xia Country.

If he says it can be done, then it can definitely be done.

Peng Shilu, Lu Shijia and others' eyes instantly became hot, and they immediately said: "Professor Qian, in this case, I think we should start the project of magnetohydrodynamic propulsion immediately."

"Yes, we must start right away. If we can develop a magnetohydrodynamic propulsion system as soon as possible, we can also greatly accelerate the research of atomic submarines."

"I think it would be better to let your students take up a position in our Institute of Atomic Power and participate in our research."

Facing everyone's eager gazes, Master Qian Wu turned his head slightly, looked at Li Mu with a smile, and said, "How about it, are you interested in taking a position at the Institute of Atomic Power?"

"Of course." Li Mu agreed without thinking.

Whether it is the surface-to-air D missile or the magnetohydrodynamic propulsion system, they are both powerful weapons for maintaining national dignity and a powerful guarantee for making the motherland strong and no longer subject to external threats!
