Material Empire

Qin Hai is a person who has been in the elite circle for many years. He knows very well that it is easy for an elite person to suffer from the problem of arrogance. The only way to cure this problem is to be better than him and convince him with your strength.

Kaan is a master, at least in the Brazilian material circle, he is qualified to show off. It is precisely because he has no opponent that he is arrogant and hopes that everyone will act according to his thinking. When encountering setbacks, he will not review what mistakes he has made, but will only shift the responsibility to the mediocre in his mind. There is no shortage of people with this kind of disease in ancient and modern China and abroad. If this disease is not cured, no matter how good a person is, they can only become factors of social instability.

Just because he understood this, Qin Hai was not in a hurry to listen to Ka An's narration, but instead found a few papers published by Tranquility, copied a set in the hotel's business center, and kept it for Ka An to read. When they came out for their honeymoon this time, they also had the intention of meeting some academic colleagues, so Tranquility brought a few masterpieces with her, and now they just used them to blow Kaan's confidence.

Sure enough, after seeing these articles and realizing that Tranquility is the author of these articles, Kaan suddenly withered. He always thought that only he could think of the principle of iron-based superconductivity, but he didn't expect that other people could agree with him. Although he didn't study these articles in detail, he could tell from a rough look that the content of the articles was very rigorous and the thinking was very clear, which meant that the author's theoretical foundation was no worse than his. The most difficult thing for him was that the author was actually a young girl. Compared with Tranquility, wouldn't he be living like a dog at his age?

At this moment, he began to regret a little bit. If he didn't fall out with the school, if he could get some funding for research in a curve, maybe the laurels of the discoverer of iron-based superconductivity would fall on his head. There are mountains beyond mountains, and there are people beyond people. Am I being too frivolous?

Seeing the wandering expression on Ka An's face, Qin Hai knew that he had taken the right medicine, and Ka An's self-confidence had obviously been hit. However, to make Ka'an serve him wholeheartedly, he needs to add some more ingredients. Thinking of this, he laughed and said to Ka'an:

Mr. Kaan, I heard from my wife that you have some genius ideas about lightning collection, and you have proposed that superconductivity and supercapacitors are the two main obstacles. In terms of superconductivity, my wife is an expert, and we have A special superconducting research center, Mr. Kaan, if you are interested, I can introduce you to work there. At present, iron-based superconductivity has not yet broken through the liquid nitrogen temperature range, and Mr. Kaan’s joining may be able to solve this problem. play a crucial role.”

Ka'an nodded lightly, and said, If there is such an opportunity, I will be very happy to accept it. It seems that my estimate of myself is too high. If possible, I hope that I can become Miss Tranquility's assistant.

Mr. Ka'an, you are too polite. Tranquility nodded slightly to Ka'an, and said humbly.

So, in terms of supercapacitors, does Mr. Kaan have any ideas? Qin Hai continued to ask.

Yes, I have also had some considerations in this regard... Looking back now, it may be an outdated idea. Ka'an replied, he was quite conceited about his attainments in this area , but after experiencing the problem of superconductivity, he began to speak cautiously.

Can you briefly talk about it? Qin Hai asked.

Yes. Ka'an said, I don't think I need to introduce the concept of supercapacitors to the two of you. It is nothing more than a larger capacity than ordinary capacitors, which can reach the ultra-large capacity of the Farad level. It is still in the United States. When I was doing my doctoral research, I had already seen the supercapacitors that existed at that time. In the past 20 years, the development of supercapacitors has also been very rapid. If I am not wrong, there are already 1,000 farads of supercapacitors in the world.”

Your estimate is completely correct. Qin Hai interjected. A few months ago, a Japanese company just developed a new type of supercapacitor, which is of the 1000 Farad level, but the volume is too large, and there is still a long way to go before it can be used practically. Qin Hai himself is also developing supercapacitors. His goal is to surpass the level of Japanese companies and shorten the distance between products and applications as soon as possible.

A capacitor is a very common component in ordinary electrical appliances. As the name implies, it is a device that can store electrical energy. The unit to measure the capacitance of a capacitor is farad, 1 millionth of a farad is called 1 microfarad, and 1 millionth of a microfarad is called 1 picofarad. The capacitors used in household appliances have a small capacity of only a few picofarads, and a large capacity of tens of thousands of microfarads, which is difficult to reach the level of farads. In addition, the size of an electrolytic capacitor of tens of thousands of microfarads is similar to that of a No. 1 battery. If the capacity is to be increased by a hundred times to reach the level of several farads, its volume can be imagined.

The so-called supercapacitor just needs to expand the capacity to the Farad level, and generally reaches thousands of Farads or even larger. To make such a supercapacitor, it is obvious that we cannot simply rely on increasing the volume of the capacitor, but require technological innovation. Qin Hai himself has some ideas about supercapacitors, but they are far from enough, so he wants to hear if the mad scientist in front of him has better ideas.

Ka'an didn't know Qin Hai's thoughts, he just continued to narrate according to his own thoughts, he said: According to my research, I think the key to supercapacitors lies in the selection of electrode materials, which need to have well-developed pores. Structure, high specific surface area, stable physical and chemical properties, in addition, there should be low cost. According to the information I saw in the past few years, there are no more than three types currently used as supercapacitor electrode materials : Carbon materials, transition metal oxides and conductive polymers, the progress of supercapacitors depends entirely on the development of these three electrode materials.

That's very well said. Qin Hai couldn't help clapping his hands, and then asked with a smile: Then, based on Mr. Ka'an's assumption, which of these three types of materials is the most promising?

Carbon! Ka'an said without thinking.

If I can provide a carbon material with high specific surface area, high physical mobility, good thermal and electrical conductivity, and a reasonable price, Mr. Kaan is interested in using it to develop an excellent ultra- Conductive capacitance? Qin Hai asked.

What material are you talking about? Ka'an looked at Qin Hai and asked.

Graphene. Qin Hai said, This is a two-dimensional carbon material composed of a single layer of carbon atoms. We have proved that its various physical and chemical properties meet the requirements you just raised.

Speaking of this, Qin Hai just rightly pushed another copy in front of Ka An, which was the detailed test report on graphene, and the various data on it could be said to be clear at a glance to those who knew the business.

After Qin Hai developed graphene, the first application direction he thought of was to develop supercapacitors. A group in the School of Materials has conducted a lot of research in this area and has made considerable progress. However, Qin Hai still felt that there was a lack of an effective academic leader, and he wanted to see if the Ka'an in front of him was a suitable candidate.

So the world is changing so fast. Ka'an sighed again after reading the information Qin Hai gave him. From his perspective, it is natural to see the role of graphene in the development of supercapacitors. This material was only in people's imagination a few years ago, but now not only has detailed physical and chemical test data, but also listened to Qin. The meaning of the sea has also achieved industrial production.

I think I'm so ridiculous. Ka'an said dejectedly, If I stayed in school, maybe I wouldn't miss these important inventions. Miss Tranquility, I take back what I said to you today, I feel that what I need now is not funding, but to go back and continue teaching.

Qin Hai waved his hand and said, Mr. Ka'an, I don't think it makes sense for you to go back to that school now. They have rejected your funding. If you go back, I'm afraid you will be left behind. I I think you have unique insights into superconductivity and supercapacitors, would you like to go to China with me, if possible, I hope you can lead a group to develop graphene supercapacitors as soon as possible.”

What, are you really going to use graphene to develop supercapacitors? Kaan asked. Supercapacitors can also be regarded as a relatively partial product. Although it has a wide range of applications, it is also very technically difficult, so few companies have invested in this area. Hearing that Qin Hai wanted to make a super capacitor, Ka'an was a little surprised, but also a little bit happy.

Of course, and we are already doing this. Qin Hai replied.

You...are also planning to build a lightning collection system? Ka'an asked hesitantly.

Qin Hai thought for a while and said, If this project is feasible, maybe we will invest in it in the future. But before that, I hope that someone can conquer these two key technologies. The use of supercapacitors is not limited to Lightning collection, I think Mr. Ka'an is very clear about this.

Of course, this is a very promising product for commercial applications, Caan said.

Qin Hai smiled and said: If Mr. Ka'an is willing to cooperate with me, then you will also get a considerable piece of this commercial cake in the future.

Go to China? Ka'an patted his head, and then laughed: I really never thought about going to China to work in my lifetime, but it seems like a good idea. If I nodded, would I just Should I call you my boss?

I prefer you to call me a collaborator. Qin Hai said, stood up and solemnly extended his hand to Ka'an, saying: I hope we can cooperate happily.

Happy cooperation! Ka'an also stood up, held Qin Hai's hand tightly, and said excitedly.
