Before the police arrived, Fang Yuanshan finally entered Andre Geim's home, a very stylish English country house. Pen, fun, and www.biquge.info

The fifty-year-old Geim looks very energetic, with a slightly chubby face and the charm of a mature man. After entering the house, Gam politely said, "Would you like to have something?"

"Thank you, just bring me a glass of soda~"

After sitting down, the Nobel laureate asked, "Can I know how you found my home?"

"You know, as long as you have the heart, everything is not a problem!"

Hearing Fang Yuanshan say something he often said in the class leader, Gam had a smile on his face. Then he said: "I'm sorry to be at the door just now, you may not know, since I announced that news with Konstantin in '04, there have been a lot of people who have come to us to do business research, and this has had a certain impact on my scientific research." ”

André Geim, who said a word, then said: "What is the high-purity graphene you just mentioned, can you show me?"

Fang Yuanshan flipped through a small transparent bottle and handed it over, "To be honest, I don't know their purity yet, and I can't even be sure if they're graphene or not. ”

He took the bottle over to Geim and said, "Oh, how can you not even know if they are graphene or not?"

"Well... ”

Gem didn't care about his face, and instead said, "I may need to do a test on their purity, if you're not in a hurry, you can wait a while~"

"Of course, please!~"

He didn't follow up, sitting alone on the couch and waiting for the results of the test. At about eight o'clock in the evening, Geim came out with a shocked face and said from afar: "It's incredible, where do you get these high-purity graphenes, it's incredible!"

Seeing that he said two "incredible" in a row, Fang Yuanshan knew that there was no problem with things. He smiled and asked, "Do you think it's possible to realize my previous idea?"

Hearing his words, Geim remembered what he had said before about covering graphene on the protective armor, and shook his head again and again: "I have answered your question countless times, graphene, as the first material composed of a single layer of atoms discovered so far, their ductility and compressive resistance are beyond doubt, but the shortcomings are also fatal. ”

Without waiting for him to ask, Geim, who was standing there, continued: "Although it shows us amazing characteristics, there is a trap here. These wonderful properties place very high demands on the quality of the sample. To obtain a graphene sample with the best electrical and mechanical properties, the most time-consuming, laborious and expensive method is required: mechanical stripping, which is to tape the graphite and peel it off by hand. ”

"Hehe, isn't that a joke?"

"Don't laugh, that's how Konstantin and I prepared graphene in 2004, and so far this is the only way to get high-quality graphene. Although the equipment and technical content required seems to be low, the problem is that the success rate is lower, and it is okay to get some samples for research, and industrial production is a joke. When it comes to industrialization, this means is useless. Even if you master the world's graphite mines, how many pieces can you peel off in a day?"

"Is there no other way?"

"Of course, there are ways, but the quality of those obtained is much worse. You have to know that the central part of a piece of graphene is a perfect six-membered ring, but the edge part tends to be disrupted and becomes a five-membered or seven-membered ring. This may not seem like a big deal, but the graphene that comes out of this way has a fragile internal structure and is prone to breakage. To make matters worse, this fracture point of graphene does not heal itself like polycrystalline metals, but is likely to continue to extend. As a result, the strength of the whole graphene is greatly reduced, and it is not even comparable to ordinary materials. ”

After listening to this gem's words, Fang Yuanshan's eyes rolled and said, "What if I just make one, do you think the sample I gave you is enough for a protective battle armor?"

"One piece?"

André Geim wondered, "What's the point of you making one?"

Fang Yuanshan can probably understand a little bit of the ideas of these scientists, and the scientific research they do is to promote the progress and development of mankind. Just like what he said just now, it is industrialization and industrialization at every turn, and if large-scale production cannot be realized, this research is really of little significance to them.

Fang Yuanshan didn't answer his question, but instead asked, "I just want to know, if you add these high-purity graphene to special alloys, can you make a set of high-strength personal protective armor?"

Geim frowned and said, "Since you have obtained such a perfect graphene sample, you should know that the large-scale process manufacturing is still in a bottleneck stage, right?"

"Of course I know, but I'm sure Professor Geim will have a way! As long as he can help me make this protective armor, I will agree to whatever the conditions!"

After he finished speaking, Andre Geim on the other side was silent, and it took a long time to arrive: "Then I will say it bluntly, the large-scale production of large-scale process manufacturing is not something that can be achieved in a short time. But ... If it's just a set of protective armor, there should be a solution. ”

"Smack~"

Fang Yuanshan snapped his fingers, and then said with a bright smile on his face: "Professor Geim, please continue~"

"Two conditions: you need to donate 50 million US dollars to my and Konstantin's personal laboratories for free, and second, while I guarantee the strength of your personal protective armor, no matter how much graphene is left, we will own it, and you can't ask for it again!"

Hearing his two conditions, Fang Yuanshan suddenly laughed. In fact, when they met, he estimated that these European and American scientists were not so pure, they had made such great discoveries in science, but in private they were no different from businessmen.

Like Edison, many people know that he was a great scientist, but how many people know that he was actually a successful businessman in private?

Without thinking too much, after he finished speaking, Fang Yuanshan stood up, stretched out his hand and said, "Then I wish us a happy cooperation~"

The following two people went directly to a high-end restaurant in the city, and Fang Yuanshan invited them, and the two of them had an in-depth discussion on the materials of the protective armor while eating.

The hardness of graphene is undoubted, but if you want the armor to meet the same requirements, the materials must also be fused. In the end, it was discussed and discussed, and it was decided to use titanium alloy as a composite material for graphene.

After dinner, the two went straight to Geim's laboratory in the East End of Cambridge to discuss the shape of the armor, and finally made a simple modification based on the appearance of Iron Man. Two sharp barbs were added to the knees and elbows, as well as the fist position.

Since Fang Yuanshan doesn't need the battle armor to provide kinetic energy and auxiliary systems, it is purely a shell, so it is really too simple, as long as the model is done well, adding high-purity graphene in the later stage will be considered a success.

He didn't ask the question of this large-scale craft manufacturing, which was the secret that Geim taught them. In the end, he designed a titanium alloy Tang knife according to the shape of the battle armor, which also needed to add graphene.

After the sample came out, Fang Yuanshan looked at the protective armor in the computer, imagining that he was wearing a graphene armor, holding a graphene Tang knife in his hand, opening a four-dimensional image, a space domain, plus telepathy and space collection, he really didn't know what kind of humanoid beast he would become?

The more he thought about it, the more enthusiastic he became, and he laughed at the computer. Professor Geim next to him poured cold water and said: "It looks good, but I'm sorry to tell you that although the titanium alloy is relatively light, such a set of titanium alloy full-body armor is at least two hundred and fifty pounds or more, are you sure you need to design it like this?"

"Hmm!I'm very sure~" Fang Yuanshan nodded fiercely...
