The Red Era, the Opening University Speech

Chapter 218: One experiment, the results far surpassed ours more than a hundred times

After thinking for a while, he replied: "Don't worry, I'm sure she will definitely not like you and will stay away from you soon."

Ask: "..."

Although the result was what he wanted, it still made him feel a little upset when he heard this.

……

After finishing his chat with Ask, Li Mu slept comfortably for an hour before getting up.

I looked at the time and it was already 1: in the afternoon.

Although it was a break, he did not relax for too long. He quickly sat down at the table, took out his notes, and began to sort out his current research status.

The Institute of Atomic Power encountered some major problems before he left.

The preparation of magnetic fluid by chemical co-precipitation is in the right direction, but the speed is too slow.

Some people even estimate that at this rate, it may take much longer to successfully research than to study traditional mechanical structures.

Therefore, this problem must be solved.

"Apart from directly providing the formula ratio, is there any other way to increase the speed of research?" Li Mu thought secretly.

It is definitely not possible to give the formula ratio. He didn't even do a few experiments. How can he explain the source of the data? It is totally untenable.

Even if others believe in his genius, the research plans for national-level military weapons must be tested.

Li Mu frowned, and suddenly his expression changed as he thought of something he had abandoned for a long time - computational materials science.

It didn’t work before because the computer power was not enough.

But now with supercomputers, the foundation has been laid for this to be possible.

Thinking of this, he immediately opened the WIFI list, found the WIFI of Jianqiao University Computer Laboratory Information, and then entered the search "computational materials science".

The equipment required for computational materials science mainly includes software tools related to computer simulation and material design, as well as physical instruments for material characterization and performance testing.

It has the same purpose as the computer simulation platform, and there is certain technical overlap in many places.

After quickly browsing through a large amount of information, Li Mu felt confident and added the material calculation software needed to implement computational materials science to his research schedule in his notes.

……

The next day, after a short rest.

Li Mu returned to the Semiconductor Research Institute and immediately took Yan Peilin, Huang Kun and Wu Xi to Wang Shoujue's office for a meeting.

He said directly: "I plan to develop a material calculation software based on the supercomputer for use in the research at the Institute of Atomic Energy and Power."

As soon as these words came out, everyone in the room couldn't help but swallow their saliva.

Is this because the R&D intensity is not enough?
"I agree with your idea, but I'm afraid our current manpower cannot support so much research." Wang Shoujue said with a wry smile.

There are only more than a hundred people in the entire Semiconductor Research Institute. It is not a right decision to continue to increase the number of people when so many research projects are being taken into consideration.

Li Mu was stunned when he heard this. Wang Shoujue would say this, which obviously meant that recruiting and outsourcing were not feasible.

Moreover, with that number of people, it is unrealistic to set up a new material calculation software R&D team.

After thinking for a while, he said, "Can we gather experts and professors in this field from all over the country? That will surely be enough."

"It is enough, but I'm afraid it won't be so easy for research institutes in various places to let people go." Wang Shoujue said.

Li Mu nodded slightly and said:

"That's enough. I'll go find Director Wu now and ask him to report to the higher-ups."

"Professor Huang, I have written a research draft. Please take everyone to look at it and discuss it."

"As soon as everyone arrives, we'll start the discussion!"

After saying this, he hurried to find Wu Youxiang and told him what he needed.

The latter called Guo Mo without saying a word.

……

Gathering technical talents from all over the country is not an easy task.

However, the reply from above was very quick, with only one sentence - expedite it and make sure Li Mu's research needs are met.

Less than two hours after Li Mu made the request, government agencies and research institutions across the country received an emergency notice.

In less than five hours, the first batch of experts and professors sent by the Institute of Computer Technology in Xiabei, Xiadong, Shenyang, Shanghai and other places were already on their way to Kyoto.

……

Here, in the laboratory of the Semiconductor Research Institute.

Li Mu still didn't know what kind of stir his request had caused across the country.

He was currently explaining the principles of the induction cooker to three intern researchers under Huang Kun:

"Induction cookers, as the name suggests, are based on the phenomenon of electromagnetic induction, using alternating current through a coil to generate an alternating magnetic field with a constantly changing direction."

"Then, a current of my choice is generated inside the conductor, ultimately achieving the purpose of heating."

"The overall structure is divided into four parts: the rectifier circuit, the control circuit, the shielding layer, the iron-containing pot on the top plate, and the most important shielding layer."

……

Li Mu first introduced the basic situation of the induction cooker, and then named an assistant researcher named Du Fei to be responsible for the research and development of the induction cooker.

He had some impression of this person. Although he was only 27 or 28 years old and still relatively young, he was down-to-earth and steady in his work, and had performed well in several projects such as electronic watches and handheld game consoles.

He is responsible for conducting the research according to the proposal he wrote, and there will basically be no major problems.

"No, Consultant Li, my ability is not enough. Let's leave it to other experienced experts and professors." Du Fei, who was called, shook his head and quickly refused.

He had just been promoted from an intern researcher to an assistant researcher, and was in charge of the development of a project, but he felt that he was not up to the task.

Li Mu said helplessly:
"It has to be done even if it's not necessary. Who else is there in the station now?"

"You three are all the members of this induction cooker development team."

"Don't worry, I have already written the proposal. As long as we develop it according to the instructions, there won't be any major problems."

After he finished speaking, he looked at Du Fei.

But the latter was obviously still hesitant.

This feels like a player in the future who plays League of Legends. Just after he passes the novice training camp, someone pats him on the shoulder and says, "Okay, you have successfully completed the apprenticeship. Next, go challenge the big devil."

——It’s impossible to do that!

Seeing this, Li Mu immediately said:

"This research and development task is related to our country's foreign exchange earnings. You should be aware of its importance."

"The country is in urgent need of a large amount of foreign exchange to fill the gaps in the economic, industrial and scientific research fields."

"The sooner it appears, the sooner the country's current predicament can be resolved, allowing our country to complete industrialization at a faster pace, no longer worrying about any threats, and free from humiliation and oppression!"

He stopped there and didn't say anything more.

However, this was enough to ignite the patriotic enthusiasm in the hearts of Du Fei and the other two.

For the people of later generations, the history of the War of Resistance against Japan has become a memory of the times, but for them now, it is still a story that their parents have heard of. The blood and tears are still there, how dare we relax even a little!

Du Fei said firmly: "Please rest assured, Consultant Li, I will do my best to develop an induction cooker!"

"Us too!" the other two shouted.

Seeing their excited expressions, Li Mu nodded slightly and said, "Don't worry, I told you, it's not a difficult research. You just need to develop it according to my plan."

"If you have any problem that you can't solve, you can ask me and I will solve it for you."

……

Afterwards, Li Mu took Du Fei and three others to find Wu Youxiang and applied for a laboratory.

But although it is called a laboratory, it is actually more like a storage room.

The Semiconductor Research Institute is now seriously short of not only staff but also laboratories.

Even though a new laboratory building is already under construction, there will still be some pretty tight times ahead.

However, the simple conditions did not affect the research enthusiasm of Du Fei and others. They quickly finished reading the proposal given by Li Mu and immediately started the discussion.

Seeing how motivated they were, Li Mu felt relieved. After giving them a few instructions, he hurried away.

……

Came to the Institute of Atomic Power.

When passing through the gate, for some reason, Li Mu clearly felt that the guards' checks had become much stricter.

He shook his head and thought that it didn't matter whether it was strict or not. The most important thing was the material problem.

After parking the bicycle downstairs of the laboratory building, he walked quickly into the laboratory next door.

Inside the room, a group of experts and professors, led by Peng Shilu and Jiang Nanying, were conducting experiments on the preparation of magnetic fluid.

The method used was the chemical co-precipitation method he had previously proposed for preparing rare earth composite ferrite magnetic fluid.

Li Mu quietly walked behind the crowd and watched the experiment together.

Peng Shilu's hands were steady. In the first step of mixing the solutions, he mixed ferrous chloride and ferric chloride in an appropriate proportion according to the ratio calculated in advance.

Then carry out the Chen Dan reaction, using ammonia or NaOH solution, stirring at high speed under certain temperature and pH conditions...

……

After the final separation and magnetic fluid formation steps, a small piece of magnetic liquid is obtained.

This is a magnetic fluid, and when there is no external magnetic field acting on it, it looks just like any other liquid.

But once an abnormal effect occurs, the appearance will change significantly, showing unique physical properties.

The magnetic fluid has been prepared, but it is not a success yet. It is just the first step.

Only when the three criteria of small particles, uniformity and high saturation magnetization intensity are met can it be considered a true success.

Peng Shilu first found a microscope to observe the condition of the particles. After a short while, he raised his head and shook it slightly: "Failure."

Upon hearing the news, everyone in the laboratory instantly showed disappointment.

"It doesn't matter. This is only the 198th experiment. It's much different than the tens of thousands of experiments when studying traditional mechanical structures." Deputy Director Jiang Nanying smiled and encouraged everyone.

When everyone heard this, they couldn't help but smile.

They are not afraid of tens of thousands of experiments, and less than two hundred failures cannot scare them at all.

Immediately, Peng Shilu asked people to continue testing the saturation magnetization intensity of the magnetic fluid sample No. 198.

Even if an experiment fails, it is still necessary to record it. The experience of failure is also experience.

Just when he finished giving the instructions and was about to continue discussing with the experts and professors, he suddenly saw Li Mu who had appeared in front of the laboratory table at some point.

"Advisor Li, you're here." Peng Shilu immediately smiled when he saw this.

Others also started to greet him.

Although the experiment did not go smoothly, this is actually the norm and everyone is very calm.

Li Mu was stunned and didn't react for a moment.

However, when he thought of the tens of thousands of experiments that Jiang Nanying had just mentioned, he quickly understood the reason.

——Failure is the norm in scientific research.

After greeting everyone one by one, Li Mu looked at the smiling Peng Shilu and said, "Director Peng, I just saw your experiment and wanted to try it. Do you think it's okay?"

It is obviously not possible to just take out the formula, but it is also reasonable to "accidentally" find one or two correct ratios.

"Okay, that's no big deal, Chiang, hurry up and prepare another set of experimental materials!" Peng Shilu said immediately.

Upon hearing this, the other experts and professors who were about to leave stopped and looked at Li Mu.

They knew that Li Mu had strong theoretical ability, but after being at the Institute of Atomic Power for so long, apart from providing guidance, they had never seen him conduct experiments.

Now that I have the opportunity, of course I want to see it for myself.

Everyone laughed and said, "Advisor Li, do you mind if we learn something?"

……

In the laboratory.

Li Mu prepared the experimental equipment, and then began to prepare the prerequisites, mixing ferrous chloride and ferric chloride in a ratio of nearly 1:2.

The ratio of 1:2 is the key parameter for obtaining ideal magnetic nanoparticles.

In order to avoid a direct success, he used close to.

Then, he controlled the temperature and pH conditions. The data in the data were 55℃~60℃ and 9 respectively. He increased these two numbers slightly, then added excess ammonia water and NaOH solution and started high-speed stirring.

……

If Peng Shilu's experiments give people the feeling of being calm and reliable, then Li Mu's experiments give people the feeling of being precise and fast throughout the whole process, with a kind of smooth and beautiful feeling.

From the beginning of the experiment to the final formation of the magnetic fluid, there was no pause for opportunities, which was a feast for the eyes.

It was not until the end, when Li Mu began to clean up the experimental equipment, that they came back to their senses and looked at the prepared magnetic fluid with different expressions.

Experience told them that this could not be a successful experiment.

But they felt as if they could succeed.

Peng Shilu glanced at Li Mu, thought for a moment, and said, "Let me do the test and see how it works."

After that, he walked forward and observed through the microscope again.

After just one look, he could not help but exclaim "Huh~" and quickly adjusted the objective lens and eyepiece to detect the magnetic fluid more carefully.

After a long while, Peng Shilu raised his head and exclaimed, "As expected of Consultant Li, with just one experiment, the results far surpassed our previous one hundred times."

“Although it has not been completely successful, the finished product data has a high reference value.”

"By setting a range for this data and then conducting experiments, I estimate that it won't take many attempts to find the most appropriate ratio."
