Vol 2 Chapter 671: This is a good idea

Qin Hai is a man who has been in the cattle circle for many years. He knows that cattle people can easily suffer from incomparable problems. The only way to cure this problem is to be more cattle than him and convince him with his strength. Read the latest chapters in full
Kaan is a bull, at least in Brazil's material circle, he is qualified to play. It is precisely because he has no opponents that he will look at everything and hope that everyone will do things according to his thinking. When encountering setbacks, he will not review his mistakes, but will only put responsibility on the "mediocre" in his mind. People with this kind of problem are not lacking in ancient and modern China, and foreign countries. If this kind of problem is not cured, people who are still cattle can only become a factor of social instability.
Because of this, Qin Hai was not in a hurry to listen to Ka'an's narrative. Instead, he found a few quietly published papers and copied a set in the hotel's business center, which was reserved for Ka'an. They went out for their honeymoon this time, and originally had the intention to meet with some academic colleagues, so Serenity was carrying a few masterpieces, and now they just came out to blow Kaan's confidence.
Sure enough, after seeing these articles and realizing that Tranquility is the author of these articles, Caen suddenly hesitated. He always thought that only himself could think of the principle of iron-based superconductivity, but he was not expected to agree with him. Although he didn't study these articles in detail, he can know that the content of the article is very rigorous and his thinking is very clear, which means that the theoretical foundation of the author is not worse than that of him. The most difficult thing for him is that the author is actually a young girl. Compared with serenity, hasn't his young age lived on dogs?
At this moment, he started to regret it a little bit. If he didn't fall out with the school, if he could get some funds for research on the curve, maybe the crown of the iron-based superconducting discoverer would fall on his head. There are mountains outside the mountain, and there are people outside the person. Is he too foolish?
The look on Kaan's face drifted. Qin Hai knew that he was getting the right dose of medicine, and Ka'an's confidence had obviously been hit. However, in order for Caan to despair to serve himself, some additional materials are needed. Thought of this. He smiled and said to Kaan:
"Mr. Kaan, I heard my wife say that you have some genius ideas for lightning collection, and proposed that superconductivity and supercapacitors are the two major obstacles. My wife is an expert in reading the latest chapters on superconductivity. We are in Jingcheng University also has a special superconducting research center. If Mr. Ka'an is interested, I can introduce you to work there. At present, iron-based superconductivity has not broken through the liquid nitrogen temperature zone. Mr. Ka's joining may solve the problem. This problem can play a key role. "
Kaan nodded slightly and said, "If I could have such an opportunity, I would be very happy to accept it. It seems that my estimation of myself is too high. If possible, I hope that I can be a assistant to Miss Tranquility."
"Mr. Ka'an, you are very polite." Serenity nodded slightly to Ka'an. Modesty.
"So, does Mr. Ka An have any thoughts on supercapacitors?" Qin Hai continued to ask.
"Yes, I had some considerations in this regard ... Now thinking back, maybe it's outdated." Kaan replied that he was quite proud of his accomplishments in this area. But after experiencing the problem of superconductivity, he began to speak cautiously.
"Can you talk briefly?" Qin Hai asked.
"Yes." Kaan said, "The concept of supercapacitors, I don't think I need to introduce them to the two. It is nothing more than ordinary capacitors with a larger capacity, which can reach fara-class ultra-large capacity. Still in my US When I did my Ph.D. research, I had already seen the supercapacitors that existed at the time. In the past 20 years, the supercapacitors have also developed rapidly. If I am not mistaken, there are now 1000 farad supercapacitors in the world. "
"Your estimation is completely correct," Qin Hai interrupted. A new type of supercapacitor just developed by a Japanese company just a few months ago is exactly 1,000 farads, but it is too bulky and there is still a lot of gaps in practical use. Qin Hai is also developing supercapacitors, and his goal is to exceed the level of Japanese companies. Reduce the distance between products and applications as quickly as possible.
A capacitor is a very common component in ordinary electrical appliances. As its name implies, it is a device that can store electrical energy. The unit for measuring the capacitance of a capacitor is the Farad. One part per million is referred to as a microfarad, and one part per million is referred to as a picofarad. The capacitors used in household appliances have only a few picofarads in small capacity, and tens of thousands of microfarads in large capacity, which is difficult to reach the level of farad. In addition, tens of thousands of microfarads of electrolytic capacitors are similar to a single-size battery. If the capacity is to be increased a hundredfold, reaching the level of a few farads, its volume can be imagined.
The so-called supercapacitors just need to expand the capacity to the farad level, and generally need to reach several thousand farads or even larger. To make such a supercapacitor, obviously, we cannot simply rely on increasing the volume of the capacitor, but we need to achieve technological innovation. Qin Hai himself has some ideas about supercapacitors, but it is not enough, so he wants to hear if the madman in front of him has a better idea.
Kaan didn't know Qin Hai's thoughts. He just continued to talk down according to his own thinking. He said: "According to my research, I think the key to supercapacitors is the choice of electrode materials. This material needs developed holes Structure, high specific surface area, stable physical and chemical properties, and in addition, there should be low cost. According to the data I have seen in previous years, there are no more than three types of materials 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 too good." Qin Hai could not help but clap his hands, then asked with a smile: "So, as for Mr. Ka'an, which of these three types of materials is the most promising?"
"Carbon!" Kaan said without thinking.
"If I can provide a carbon material that has a high specific surface area, high physical mobility, good thermal and electrical conductivity, and a reasonable price, Mr. Ka'an is interested in using it to develop an excellent Conductive capacitance? "Qin Hai asked.
"What material are you talking about?" Kaan asked, looking at Qin Hai.
"Graphene." Qin Hai said, "This is a two-dimensional carbon material consisting of a single layer of carbon atoms. We have proven that its various physical and chemical properties meet the requirements you just raised."
Having said that, Qin Hai just rightly shoved another copy in front of Ka'an, which is a detailed test report on graphene. The above data can be said to be clear to those who know it.
After Qin Hai developed graphene, the first application direction that came to mind was the development of supercapacitors. A team of the School of Materials has done a lot of research in this area and has made considerable progress. However, Qin Hai still felt that he lacked a competent academic leader. He wanted to see if this Kaan was a suitable candidate.
"It turned out that the world is changing so fast." Kaan sighed again after reading the information Qin Hai gave him. In his eyes, it is natural to see the role of graphene in the development of supercapacitors. This material only stayed in the imagination of people a few years ago, and now not only has detailed physical and chemical test data, but also listens to Qin The meaning of the sea has also achieved industrial production.
"I think I'm so ridiculous." Ka An said sternly, "If I stay in school, maybe I won't miss these important inventions. Miss Quiet, I take back what I said to you today, I think what I need now is not funding, but going back to teaching. "
Qin Hai waved his hand and said, "Mr. Ka'an, I don't think it makes any sense to go back to that school now. They have refused to subsidize you. If you go back, I'm afraid I can only sit on the cold bench. I I think you have unique insights on superconductivity and supercapacitors. Are you willing to follow me to China? If possible, I hope you can lead a group to develop graphene supercapacitors as soon as possible. "
"What, do you really plan to develop supercapacitors with graphene?" Kaan asked. Super capacitor is also a relatively partial product. Although its application range is wide, but the technical difficulty is also very large, so few companies invest in this area. I heard that Qin Hai wanted to make a super capacitor, and Kaan was a bit surprised, but also a bit pleased.
"Of course, and we are already doing this." Qin Hai replied.
"You ... plan to do a lightning collection system?" Kaan asked hesitantly.
Qin Hai thought for a while and said, "If this project is feasible ~ EbookFREE.me ~ maybe we will invest in the future. But before that, I hope someone can overcome these two key technologies. Super The use of capacitors is not limited to lightning collection. I think Mr. Ka'an is very clear. "
"Of course, this is a very promising product," Kaan said.
Qin Hai said with a smile: "If Mr. Kaan is willing to cooperate with me, then you will also get a considerable piece of this business cake."
"Going to China?" Ka'an patted his head, then laughed: "I really didn't think about going to work in China in my lifetime, but this seems to be a good idea. If I nod, is it me? Is it time to call you my boss? "
"I prefer you to call me a collaborator." Qin Hai said, standing up and solemnly reaching out to Ka'an, "I hope we can cooperate happily."
"Happy cooperation!" Ka An also stood up, held Qin Hai's hand tightly, and said excitedly. To be continued.
