Everyone has played with magnets when they were young. They know what magnetism is and how strong magnets are. In ordinary people's impression, if a magnet the size of a fingernail is attached to an iron object, it only takes two
It can be easily broken off with your fingers. But this time, what they saw overturned their common sense. What kind of magnet is this!
The gate is obviously not a suitable place for science popularization, so a special "Strong Magnetic Materials Exhibition Area" was set up where everyone just entered the venue. In this exhibition area, there are pictures, texts, videos and other information.
The principles, properties, applications of strong magnetic materials, etc., and there are many games designed based on strong magnetic materials. For example, you can use countless short magnetic rods to build a very strong Eiffel Tower, and a magnetic head as thick as a mung bean.
It can pick up iron pipes weighing dozens of kilograms, and there is also a magnetic levitation rail car made of permanent magnet materials. A group of well-dressed spectators sat on this floating car like children and had a great time.
Joris also wanted to stay in this exhibition area and play with all kinds of fun things, but he came with a reporting mission. No matter whether he had money or not, he couldn't be willful. He sat in fear and sat on a table held by strong magnetic materials.
I swayed on the swing a few times, allowing the cameraman to capture this thrilling scene, and then left the strong magnet exhibition area and continued moving forward.
The entire exhibition hall is divided into dozens of exhibition areas, each exhibition area corresponds to one or several related materials. Similar to the previous situation, the exhibitions in each exhibition area place great emphasis on entertainment features, or use various
Plant fancy materials to dazzle visitors’ eyes, or design various participation projects to let people experience the magic of materials for themselves.
Joris was naturally at home in such an interesting exhibition. He held a microphone in his hand and chattered non-stop, pretending to be cute, and swept through one exhibition area after another:
"Let's take a look... This is the solar materials exhibition area. What is on display here is the solar panel. Yes, as long as you shine a flashlight on this panel, we can see the electric fan connected to it.
It started to rotate...I have to say, the wind is still very strong, I feel a little cold..."
"...We finally escaped from the cold solar energy exhibition area. What, you said I still have the flashlight from that exhibition area in my hand? No, no, no, I don't want to return the flashlight to the lovely explainer just yet, because in this
It has a greater effect in the exhibition area. Have you seen it? There is a wall on the opposite side. As long as I shine the flashlight on the corresponding position on that wall, that wall will make different sounds...
Let's give it a try. Wow... it's so interesting. I now strongly suspect that there are a dozen Chinese people hiding behind the wall, and they change the records according to the light of my flashlight. I got behind the wall, and there is no
The real secret we are looking forward to lurking is on this wall. Here is a description: The material on this wall is called photosensitive ceramics, which can sense changes in light..."
"Look, there's an interesting place ahead. Let's go and take a look... No, no, no. I'm not going to pass this suspension bridge because the four ropes hanging from the bridge... What did you say? Bobby, you said they
Not a rope, just four wires? Yes yes, I agree with you, they are literally thinner than my headphone cables…
Look, two fat men weighing more than 200 pounds have walked to the bridge. I bet that they will fall off... Okay, I admit that I lost the bet, these four wires actually
It really withstood 400 pounds of weight. Let me see, there is a description here. It says that this line uses high-strength and high-modulus polyethylene fiber, and the abbreviation is hshmpe... Are you sure that such a long abbreviation is still called an abbreviation?"
"Okay, okay, we finally returned to the forest. Look, there is a river here. Of course, it is just a model of a river. The water in the river is turbid. What experiments are they doing... Oh, they installed it by the river.
A polymer permeable membrane, a miracle happened, the river water became clear after passing through this membrane.
Let's listen to what scientists have to say. They say that this kind of membrane can be used to filter drinking water on the battlefield, and can filter dirty water to drinking standard. Bobby, come here, you just said you are thirsty, I plan to do it now
Shhhhhh, then filter it into drinking water for you to drink..."
"..."
Almost all the visitors, like Joris, were dazzled in the exhibition hall. For the first time in their lives, they knew that there are so many magical materials in the world, such as electrical functional materials, sensitive materials, magnetic functional materials, new
Energy materials, smart materials... If they don't understand the characteristics of these materials, there are rich introductions and physical displays on the booth, which is enough for everyone to understand.
Even the steel, cement, ceramics, plastics, etc. that everyone is familiar with every day, also changed their appearance at the exhibition, and people were surprised that they also have so much attention to detail. Take ceramics as an example, ceramic knives for cutting fruits are not necessary.
Having said that, there are actually ceramic turning tools that can be used to cut metal. It is said to be harder than diamond, and can truly cut iron like mud. Wait, isn’t ceramic itself mud? Use something made of mud to cut it.
Iron, peel the iron until it looks like clay...Did this mess up the rhythm of the script?
The general public can only watch the excitement, while some experts in the industry are studying the new trends of these materials. As for visitors from manufacturing companies, they are thinking more about whether these materials will affect their product design and whether they can
They cannot take their products to a new level.
In a luxuriously decorated VIP room upstairs in the exhibition hall, more than a dozen people are sitting on a circle of sofas. In the middle is an elderly man with a gentle smile on his face, who is listening to the exhibition organizer and deputy director of the Planning Commission.
Wang Hongsheng’s report:
"Chief, this is the purpose of our exhibition. It is mainly to popularize the knowledge of materials science to the public and arouse the society's attention to materials. In the manufacturing industry, materials and processes are the two major elements, and they are also the key to the relationship between my country's manufacturing industry and There are two biggest gaps between foreign countries. Taking aero engines as an example, we can imitate foreign engines and manufacture identical blades and turbine disks. However, because high-temperature resistant materials lag behind foreign countries, the service life of the engine is only 10% of the advanced foreign levels. one."
The chief nodded and said: "Yes, I just saw your introduction materials on aviation high-temperature materials in the exhibition area, and I was deeply touched. In the past, the Science and Technology Commission also reported this issue to the central government, but it is undeniable that the central government has
The attention in this area is far from enough, the investment is too little, and there are too many debts."
Wang Hongsheng said: "Materials are a century-old project. Factories and equipment can be purchased, and many industrial products can be imitated. However, material formulas and processes cannot be imitated. You can only explore by yourself, and this time may take decades or even more.
Hundreds of years. Therefore, other things can be delayed, but material research cannot be stopped for a moment."
The leader turned his head, looked at Qin Hai who was sitting on the edge, and said: "Comrade Xiao Qin, I heard that you built a materials college yourself and hired hundreds of outstanding materials experts from various universities and scientific research institutions.
Is there such a thing as working at your place?"
As soon as the chief said this, officials from various departments who participated in the talks turned their attention to Qin Hai. Some of these people had known Qin Hai before, such as Yang Xinyu, Cui Hongchun, and Deputy Director Bai of the Science and Technology Commission.
Everyone knows something about Anhe Institute of Materials Science. There are also some officials who only came into contact with Qin Hai when they came to visit the exhibition today. They didn't know that he had such a big hand. They were shocked when they heard the chief's words.
A private company has poached hundreds of scholars from universities and scientific research institutions. This is in any case a matter of tearing down the country. When the leader raised such a question in person, was he trying to hold this young man accountable?
Qin Hai was not surprised by the chief's question. He knew that a few days ago, the chief had summoned Mr. Shi, Mr. Li and others specifically regarding the issue of the materials exhibition. These leaders told the chief during the meeting
He talked about the situation of the domestic materials science community and mentioned Qin Hai and his Anhe Institute of Materials Science and Technology. Teachers and Mr. Li all have their disciples and disciples working at Anhe Institute of Materials Science and Technology. They also heard about the reasons why. When introducing it to the chief, they were very knowledgeable.
Praise for Qin Hai.
With this kind of foreshadowing, the leader's raising of this issue should be just a show of pretense, rather than questioning Qin Hai for raising an army. Qin Hai believed that what he did could withstand scrutiny, so he felt very at ease.
"Chief, the situation you mentioned does exist. Our Daqin Industrial Group has an Anhe Materials Institute. Currently, hundreds of domestic outstanding materials scientists work there. Many of the materials scientific research achievements you see today came from Anhe.
School of Materials Science." Qin Hai replied calmly.
The leader asked: "These scholars are the backbone of various schools and research institutes. If you poach them all like this, wouldn't you be robbing the country?"
Qin Haidao: "Chief, you misunderstood. I didn't dig these people, I just fished them out."
"Haha, catch it up? This is a new idea, tell me about it." The chief said with a smile. As Qin Hai analyzed, the chief did not mean to blame Qin Hai, he just wanted to hear what Qin Hai said
Just explain your behavior.
Qin Haidao: "These scholars recruited by Anhe Institute of Materials Science and Technology are all those who have difficulty staying in their original units and are ready to go to sea or go abroad. Even if I don't take them in, they will not stay in their original units. Rather than letting them all
If you jump into the sea, you might as well be caught by me in a net and kept in the School of Materials Science. At least you can preserve the seeds of material science research for the country."
"Is this really the case?" the chief asked, staring at Qin Hai. (To be continued...)
