Everyone has played with magnets when they were young, and they know what magnetism is and how strong the magnetism is. In the impression of ordinary people, if a magnet the size of a fingernail is attached to a certain piece of iron, it can be easily broken off with just two fingers. But this time, what they saw subverted their common sense, what kind of magnet is this!

The gate is obviously not a suitable place for popular science, so in the place where everyone just walked into the venue, a "strong magnetic material exhibition area" was specially set up. In this exhibition area, there are pictures, texts, videos and other materials to introduce the principle, performance, application and so on of strong magnetic materials, as well as many games designed based on strong magnetic materials. For example, a very strong Eiffel Tower can be built with countless short magnetic rods, a magnetic head the thickness of a mung bean can suck up dozens of pounds of iron pipes, and there are maglev rail cars made of permanent magnet materials.

Joris also wanted to stay in this exhibition area and play all kinds of fun things, but he came with a reporting mission, and he couldn't be willful whether he had money or not. He sat down in fear and dangled a few laps on a swing held by a strong magnetic material, allowing the cameraman to capture the thrilling scene, and then left the strong magnetic exhibit and continued to move forward.

The entire pavilion is divided into dozens of exhibition areas, each corresponding to one or more related materials. As in the previous cases, the exhibitions in each section have a strong emphasis on entertainment, either blinding visitors with a variety of fancy materials, or designing various participatory programs to allow people to experience the magic of materials firsthand.

With such an interesting exhibition, Joris is naturally like a fish in water, holding the microphone in his hand. chattering, pretending to be cute and cute, sweeping from exhibition area to exhibition area:

"Let's take a look...... This is the solar materials exhibition area, and solar panels are exhibited here. That's right, as soon as you take a flashlight and shine it on this board, we see that the electric fan connected to it starts turning...... I have to say. The wind was still very strong and I felt a little cold......"

“…… We finally escaped from the cold solar exhibit, what, you say I still have a flashlight in that exhibit in my hand? No, no, no, I don't want to give the flashlight back to the lovely docent just yet, because it's more useful in this area. See, there's a wall on the other side, and as long as I shine the flashlight on the corresponding position on that wall, that wall will make a different sound......

Let's give it a try. Wow...... It's just so much fun. I now very much suspect that there are a dozen Chinese hiding behind the wall who change records according to the light of my flashlight. I went to the back of the wall, there was no lurker we were expecting, the real mystery was on this wall, and here it was written: the material on this wall is called photosensitive ceramic, which can sense changes in light......"

"Look, there's an interesting place ahead, let's go over and have a look...... No, no, no. I don't plan to pass the suspension bridge in Guò because there are four ropes hanging from the bridge deck...... What did you say. Bobby, you say they're not ropes, just four threads? Yes yes, I agree with you, they are simply thinner than my headphone cable......

Behold, two fat men weighing more than 200 pounds have come to the bridge. I bet they're going to fall down...... Well, I'll admit I lost the bet, and those four wires actually really carried 400 pounds. Let me see, here's the instructions. It is said that this kind of wire 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? ”

"Alright, well, we are finally back in the forest, and behold, there is a river, of course, just a model of a river. The river is muddy, what are they doing...... Oh, they installed a polymer permeable membrane by the river, and a miracle happened, the river water became clear through this membrane.

Let's hear what scientists have to say, they say that this membrane can be used to filter drinking water on the battlefield, and it can filter dirty water to drinking standards. Bobby, come here, you said you were thirsty, I'm going to shush it now, and then filter it into drinking water for you......"

“……”

Almost all of the visitors were just as dizzy as Joris was in the pavilion. For the first time in their lives, they knew that there are so many magical materials in this world, such as electrical functional materials, sensitive materials, magnetic functional materials, new energy materials, and smart materials...... If they don't understand the characteristics of these materials, there are rich introductions on the booth, as well as physical displays, which are enough for everyone to understand.

Even the steel, cement, ceramics, plastics, etc., which are commonplace in everyone's daily life, have changed their appearance at the exhibition, and people are surprised that they have so much exquisiteness. Take ceramics as an example, not to mention the ceramic knife for cutting fruits, there are also ceramic turning tools that can be used to cut metal, which are said to be harder than diamonds, and have truly reached the realm of sharpening iron like clay. Wait, isn't the ceramics themselves clay? Sharpen iron with something made of clay and sharpen the iron like clay...... Is this a mistake in the rhythm of the script?

The general public is confined to the excitement, and some industry experts are hurrying to study the new trends in these materials. As for visitors from manufacturers, they think more about whether these materials will affect their product design and whether they can take their products to the next level.

In a luxuriously decorated VIP room upstairs in the pavilion, a dozen people sit on a circle of sofas. In the center is an elderly man with a gentle smile on his face, listening to the report of Wang Hongsheng, the organizer of the exhibition and deputy director of the Planning Commission:

"Chief, this is the purpose of this exhibition, which 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 two aspects with the largest gap between China's manufacturing industry and foreign countries. Taking aero engines as an example, we can imitate foreign engines to manufacture exactly the same blades and turbine disks, but because the high-temperature resistant materials are backward than foreign ones, the service life of the engine is only one-tenth of the advanced level abroad. ”

The chief nodded and said, "Yes, I just read your introduction materials on aviation high-temperature materials in the exhibition area, and I was very touched." In the past, the Commission of Science, Technology and Industry also reported to the central authorities on this issue, but it is undeniable that the central government's attention to this aspect is far from enough, with too little investment and too many debts. ”

Wang Hongsheng said: "Materials are a century-old plan. Factories and equipment are available, and many industrial products can be imitated, but material formulas and processes cannot be imitated, and they can only be explored by themselves, and this time may take decades or even hundreds of years. Therefore, other things can be delayed, and the research of materials cannot be stopped for a moment. ”

The chief turned his head, looked at Qin Hai, who was sitting on the edge of one side, and said: "Comrade Xiao Qin, I heard that you have built a materials college by yourself, and hundreds of outstanding materials experts from various universities and scientific research units have been recruited to work with you, is there such a thing?" ”

As soon as the chief's remarks came out, the officials of various departments participating in the talks all set their eyes on Qin Hai. Among these people, some of them knew Qin Hai before, such as Yang Xinyu, Cui Hongchun, and Deputy Director Bai of the Science and Technology Commission, etc., who more or less knew about Anhe Institute of Materials. In addition, some officials only came into contact with Qin Hai when they came to visit the exhibition today, and they didn't know that he had such a big hand, and they were shocked when they heard the chief's words.

A private company that poached hundreds of scholars from various universities and research institutes is a matter of tearing down the corners of the country anyway. When the chief asked such a question in person, did he mean that he wanted to hold the young man responsible?

Qin Hai was not surprised by the chief's question, he knew that a few days ago, the chief summoned Shi Lao, Li Lao and others specifically on the issue of the material exhibition. During the meeting, these leaders talked to the chief about the situation of the domestic materials science community, and mentioned Qin Hai and his Anhe Institute of Materials. Shi Lao and Li Lao both have apprentices and grandchildren working in Anhe Materials College, and they also heard the reason, and when they introduced it to the chief, they had no shortage of praise for Qin Hai.

With such foreshadowing, the chief should have raised this question just as a pretense and not as a matter of asking Qin Haixingshi for his crimes. Qin Hai believed that what he did could withstand scrutiny, so he was very down-to-earth.

"Chief, the situation you said does exist, we have an Anhe Institute of Materials under Daqin Industrial Group, and there are currently hundreds of outstanding domestic materials scientists working there. Many of the materials research achievements you see today are from the Anhe Institute of Materials. Qin Hai replied calmly.

The chief asked: "These scholars are the backbone of various schools and research institutes, and if you poach them all like this, won't you pry the corners of the country?" ”

Qin Haidao: "Chief, you misunderstood. I didn't dig these people, I just fished them up. ”

"Haha, fish it up? That's a new way of saying it, tell me about it. The chief said with a smile. As Qin Hai analyzed, the chief didn't mean to blame Qin Hai, he just wanted to hear how Qin Hai explained his behavior.

Qin Haidao: "These scholars recruited by Anhe Materials Institute are all difficult to stay in their original units and are ready to go to the sea or go abroad. Even if I don't take them in, they won't stay in their original unit. Instead of letting them all jump into the sea, it is better for me to fish them up with a net and raise them in the School of Materials, at least to keep the seeds of material research for the country. ”

"Is that really the case?" The chief stared at Qin Hai and asked. (To be continued......)
