From University Lecturer to Chief Academician

Material manufacturing, looking for professionals.

The manufacture of granular materials involves metal precision processing technology. Wang Hao found the top domestic precision engineering expert Yang Yun and academician.

Yang Yunhe is an academician of the Chinese Academy of Engineering.

He is a graduate of materials engineering from Harvard University, has a double doctorate in mechanical and materials engineering, has won the Alfred Sloan Award, the Science Foundation Waterman Award and other honors, and was hired as a tenured professor by the University of California, Berkeley .

Later, Yang Yunhe decided to return to China for development and served as the dean of the School of Physical Science and Technology of Donggang University, and was elected as an academician of the Academy of Engineering during his term of office.

After leaving Donggang University, Yang Yunhe entered the top domestic precision engineering company "Donggong Precision", focusing on improving the research of metal-related manufacturing technology.

Wang Hao's itinerary is still very secretive.

Instead of going to the R\u0026D department of Donggong Precision Company, he went to an academic conference venue related to metal manufacturing. In the small room on the side, he waited for Yang Yunhe who came to attend the conference.

Yang Yunhe was very enthusiastic when he saw Wang Hao. He came over to shake hands and said, "Mr. Xu called me. I never expected, Academician Wang, that you would come here in person."

"You're welcome."

Wang Hao exchanged pleasantries, and said, "I have no choice but to study in such a hurry. In the field of domestic precision engineering, Donggong Precision is the most cutting-edge. Academician Yang, you are the top expert."

Yang Yunhe was no longer modest, and asked directly, "What are your specific needs?"

Wang Hao took out the drawing and pointed to the granular image drawn on it, "I would like to ask, with Donggong Precision's technical capabilities, how small can a metal material of this shape be made?"

Yang Yunhe took a look at the drawing, frowned and asked, "Is the precision required?"

Wang Hao thought for a while and said, "High precision is not required, but the overall deviation should not be too large. We want to make such metal particles."

"...A millimeter or so."

Yang Yunhe hesitated for a moment, then continued, "The difficulty in making this shape lies in the semicircular depressions on the lower three sides, and the semicircular protrusions on the top."

"Model design must be carried out first, but because it is too small, errors will definitely occur."

"If it is lower, you need to research the plan, it may not just be purely physical cutting and manufacturing of metal."

He paused as he spoke, thought about it and continued, "Academician Wang, you should know about chips, right? I'm not talking about making nano-sized particles, but because of the complex shape, as long as you make particles smaller than millimeters, you can A similar technology is needed."

"This cannot be done directly, and a systematic system needs to be perfected."

Yang Yunhe continued to explain a lot.

Wang Hao thought about it and said, "That is to say, if it is to manufacture particles with a size of more than a millimeter, it can be directly produced after a design, but if it is smaller, it will be difficult, right?"

Yang Yunhe nodded, "No matter how small it is, it can't be solved simply by cutting and plasticizing."

"Of course, if you do special research regardless of the cost, you can also find a way to make finer particles, but it will take a lot of investment and time."

Wang Hao has a plan in his heart.

...

The answer Yang Yunhe gave was better than expected.

Wang Hao thinks that it is difficult to manufacture millimeter-scale particles, after all, the shape of the particles on the drawing is too complicated.

For now, millimeters are enough for the time being.

He chatted with Yang Yunhe again, and knowing that the other party was going to attend the meeting, he didn't bother him anymore, but returned to Xihai University.

Originally, I wanted to go directly to the annihilation force field experiment base, but after thinking about it, I went to the Nano-micro Materials Laboratory to find Xia Guobin who was busy.

Xia Guobin is still doing research on the micro-behavior of superconducting alloys.

When Wang Hao arrived at the laboratory operation room, Xia Guobin was busy in a white coat. He turned his head and saw Wang Hao, and came out after explaining a few words to others.

"Academician Wang, you are here!"

Xia Guobin greeted and immediately said, "Our research has not found anything recently."

There was a bitterness in his voice.

When Wang Hao came to talk about research, he felt that the asking price of 5 million was too high, so he automatically lowered it to 4 million.

It was only later that I found out that the other party had prepared 20 million yuan.

Twenty million has become four million, and it feels like the heart has been stabbed severely.

Wang Hao didn't care about Xia Guobin's tone, but said, "It's not for the project, this time I'm here to ask a question."

"What?"

Xia Guobin's expectation suddenly became confused. He couldn't think of any questions Wang Hao would ask himself.

Wang Hao took out the blueprint of the granule plan, spread it on the table and said, "Professor Xia, look at this three-dimensional figure. It is a thirteen-sided body, with one semicircle protruding on the upper side and concave semicircle on the lower three facets."

"Uh-huh."

Xia Guobin nodded while watching.

"You are an expert in nano-micro materials, is there a way to make micron-sized metal particles shaped like this?"

"—?"

Xia Guobin froze with his mouth half open.

He reacted for a long time before he seemed to come back to his senses, and asked with an exaggerated expression, "Microscale? Such a complicated structure?"

"yes?"

Xia Guobin pursed his lips hard.

He was silent for more than ten seconds, and said, "Academician Wang, when you came to Xihai University, do you remember what research we were doing?"

"...microsphere separation?"

"right!"

Xia Guobin nodded vigorously, "At that time, we cooperated with Chuangwei Group to study and separate micron-sized conductive microspheres. The manufacture of those conductive microspheres, in simple terms, is heating, stirring, and separation..."

"Metal balls on the micron scale can only be made by such a simple method. The graphics you take out are so complicated that they must be cut finely at the centimeter level..."

Needless to say the follow-up.

Xia Guobin had a look of lovelessness on his face, as if to say 'are you kidding me'.

Wang Hao also became silent.

He pursed his lips and frowned as he thought about it, and after a minute or so he suddenly said, "Microsphere manufacturing... Come and tell me in detail."

"You ask this?"

"yes."

"Academician Wang, are you kidding me?"

"certainly!"

"……All right."

...

The manufacturing process of conductive microspheres, as described by Xia Guobin, can be simply understood as 'heating, stirring, and separation'.

When a certain material is placed in molten metal liquid and dispersed by physical means, it will naturally separate into fine balls.

The surface of the ball is contaminated with metal, and it has conductive properties.

This process makes use of material properties.

On the way to the annihilation force field experiment base, Wang Hao kept thinking about the process mentioned by Xia Guobin. He felt that the manufacture of microspheres and granular materials had some commonality.

Microsphere manufacturing utilizes material physical properties;

During the conduction process, a semi-topological structure is formed inside the material, which is also a microscopic physical characteristic.

If a strong voltage environment can be created and the molten metal material is placed in it, as long as a current of sufficient strength passes through it, semi-topological structures will be formed inside the molten metal material.

In this state, can metal particles similar to the semi-topological structure be separated one by one by using some physical means?

"The granular design is designed according to the material layout that stimulates anti-gravity, but in essence, it is infinitely close to the semi-topological structure inside the conductor."

"The semi-topological structure is a physical characteristic, which is related to the ionic lattice, but not exactly the same. It can be considered as a bond structure that can be squeezed..."

"In the superconducting state, the semi-topological structure will be flattened, allowing a large number of electrons to pass through without hindrance. From this perspective, the semi-topological structure will impose certain restrictions on electronic activities..."

"Then under the special high-voltage environment, the semi-topological structure and external physical interference may also produce some kind of continuity..."

Wang Hao thought carefully, and finally decided, "This technology is definitely difficult. But if you want to manufacture micron-scale granular materials, this may be a good direction."

He has arrived at the experimental base.

The purpose of coming to the experimental base this time is to conduct a DC anti-gravity measurement experiment of materials.

DC anti-gravity is different from AC anti-gravity.

Now the annihilation force field experiment team has mastered four annihilation force field technologies, one is the conventional communication anti-gravity technology, which is to create an upward anti-gravity field.

This technology has been included in the ranks of "basic technology", and it can only be used to measure the anti-gravity characteristics of materials.

The second is the exchange of horizontal anti-gravity technology, which is used by the air-ship series of aircraft.

The third is the DC anti-gravity technology. The DC anti-gravity technology is an improvement on the F-ray technology. One piece of equipment can be squeezed by a spiral magnetic field to create a thin layer of strong annihilation force field to excite the F-ray.

The last is the direct current strong annihilation force field technology.

The latter two technologies still use high-pressure hybrid materials, because metal materials cannot excite the annihilation force field characteristics when they reach a superconducting state.

The current DC anti-gravity measurement experiment is to determine whether a superconducting material containing first-order iron and first-order lithium and having conventional anti-gravity properties has DC anti-gravity properties.

Wang Hao had already contacted Liao Jianguo in advance, asking them to send a technical team over, and asked Liu Yunli to come by name.

After Liao Jianguo got the news, he personally led the team over.

They have been waiting for a day.

"Academician Wang, you are here!"

Liao Jianguo saw Wang Hao with enthusiasm, "What is the new experiment? It is said to be related to metal materials?" He was really looking forward to it.

Wang Hao nodded, "There are several materials that have anti-gravity properties, and we are going to use them to try to create a DC anti-gravity field."

"That would be great!"

Liao Jianguo expected, "If it can replace the high-pressure hybrid material, the excitation of F-rays will become easier, and the room for improvement will be greater."

"The most important thing is that metal materials can greatly improve the stability of the device."

Tang Jianjun immediately added, "In this way, we can use related technologies to create containers for nuclear fusion reactions."

"..."

Liao Jianguo looked at Tang Jianjun but didn't want to speak. He felt that the old guy had 'betrayed'.

When the F-ray experiment team was first established, Tang Jianjun volunteered to join in, with the purpose of learning about related technologies and seeing if he could develop and research nuclear fusion technology.

Tang Jianjun is the top nuclear magnetic expert, and his personal research field is just right. Even for the F-ray experiment group, it is not easy to recruit such an expert.

Liao Jianguo was naturally very happy.

result……

When it was discovered that the research on the annihilation force field experimental base could produce a container for controlling nuclear fusion, Tang Jianjun stayed at the experimental base for a long time and never left. Here we go.

Doesn't that mean you won't go back?

Liu Yunli stood aside and watched with a straight smile, but he felt that Tang Jianjun's actions were not wrong.

Although Liao Jianguo had a good relationship with him, and they even complained about the unscrupulous and unprincipled Academician Tang, but from the perspective of technology research and development capabilities, the Annihilation Force Field Experimental Base is the only way to make technology leap forward.

The F-ray experiment group is also useful, but no matter how much research is done, it will only make a small improvement and upgrade of the technology.

Now the team still wants to come here to participate in the experimental research.

Here is the proof.

Wang Hao and Liao Jianguo exchanged a few words, and then went to check the materials used in the experiment together.

There are seven materials in total.

Among them, FCW-031, which has the highest anti-gravity properties, also includes FCW-025, FCW-028, FCW-041, etc., which are all superconducting materials containing first-order iron elements.

FCW-025 is also very special, it contains the first-order lithium element, and it is also the only material that contains the first-order iron-lithium double element.

After looking at several materials together and discussing a few words about the experiment, Liao Jianguo went out and asked Wang Hao, "Academician Wang, do you think that among these materials, materials with DC anti-gravity properties can be found?" ?”

A group of people looked at Wang Hao.

Wang Hao said hesitantly, "I'm not sure, there may be one or two? I hope to find out." He shook his head vigorously, showing a helpless look.

Then, walk away.

Liao Jianguo was immediately disappointed, "Even Academician Wang is not sure, it seems... there is not much hope!"

"yes?"

Tang Jianjun was about to express his agreement when he suddenly remembered the two previous experiments and what Xiang Qiansheng said to him.

So he decided not to comment.

Liu Yunli smiled and said, "Based on what I know about Academician Wang, since he said there might be one or two, there is great hope."

"Why?"

Liao Jianguo looked over incomprehension.

Liu Yunli explained, "Academician Wang is just not sure, but he is definitely confident, and what he said is 'one or two' rather than 'one is good'."

"Notice the difference!"

"I said so, do you understand?"

"..."

"..."

Liao Jianguo and Tang Jianjun fell silent together. They didn't know what to say, but they had to pay attention to the difference in words in their daily speech.

Liao Jianguo pursed his lips hard, patted Liu Yunli on the shoulder for a long time, sighed and said, "How do I feel, academician Wang is like the emperor, and you people are like courtiers who flatter the emperor, and you still study The emperor speaks regularly."

"It's... so professional!"

There was sarcasm in his voice.

Tang Jianjun nodded in support, thinking that Xiang Qiansheng felt the same way.

"I didn't try to figure it out on purpose!"

This time it was Liu Yunli's turn to sigh.

There was some sadness in his voice, and he said with a wry smile, "This is the law that I have summed up after being hit too many times and having too many ups and downs in my mood..."
