Qin Hai is a person who has been in the circle of talented people for many years. He knows very well that talented people can easily contract the problem of being arrogant. The only way to cure this disease is to be better than him and impress him with your strength.
Ka'an is a great person, at least in the Brazilian material circle, he is qualified to show off. Precisely because he has no opponents, he is arrogant and hopes that everyone will do things according to his thinking. When encountering setbacks
Sometimes, he will not examine his own mistakes, but will only shift the responsibility to the "mediocre people" in his mind. There is no shortage of people with this kind of problem in ancient and modern times, both at home and abroad. If this kind of problem is not cured, no matter how awesome they are,
People can only become an unstable factor in society.
Because he understood this, Qin Hai was not eager to listen to Ka'an's narrative. Instead, he found a few papers published by Ning Jing and made a set of copies in the hotel's business center, specially reserved for Ka'an to read. They
When I went out for my honeymoon, I originally had the intention of meeting some academic colleagues, so Ning Jing brought a few masterpieces with me, and now I just took them out to knock Ka'an's self-confidence away.
Sure enough, after Ka'an saw these articles and realized that Jingjing was the author of these articles, he suddenly withered. He always thought that he was the only one who could think of the principle of iron-based superconductivity, but unexpectedly others
It coincided with him. Although he did not study these articles in detail, but from a rough glance, he could tell that the content of the articles was very rigorous and the ideas were very clear, which means that the author's theoretical foundation
Not worse than him. The most difficult thing for him to let go is that the author is actually a young girl. Compared with Ning Jing, isn't his age like a dog?
At this moment, he began to feel some faint regrets. If he had not fallen out with the school, and if he could have obtained some funds for research in a curve, maybe the crown of discoverer of iron-based superconductivity would have fallen on his head.
There are mountains outside the mountains, and there are people outside the people. Am I being too frivolous?
Looking at the uncertain look on Ka'an's face, Qin Hai knew that he had taken the right medicine. Ka'an's self-confidence had obviously been hit. However, it would take more to make Ka'an serve him wholeheartedly.
Just add some ingredients. Thinking of this, he chuckled and said to Ka'an:
"Mr. Ka'an, I heard from my wife that you have some genius ideas about lightning collection, and you have proposed that superconductivity and supercapacitor are the two main obstacles. My wife is an expert in superconductivity. We have other experts at Kyungseong University
A specialized superconducting research center. If Mr. Kaan is interested, I can introduce you to work there. At present, iron-based superconductors have not yet broken through the liquid nitrogen temperature range. Mr. Kaan's joining may be able to solve this problem.
play a key 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 Ning Jing's assistant."
"Mr. Ka'an, you are too polite." Jingjing nodded slightly to Ka'an and said humbly.
"So, in terms of supercapacitors, does Mr. Ka'an have any ideas?" Qin Hai continued to ask.
"Yes, I have had some considerations in this area... Looking back now, maybe it is an outdated idea." Ka'an replied, he was originally quite conceited about his achievements in this area.
, but after experiencing the problem of superconductivity, he began to become cautious in his words.
"Can you tell me briefly?" Qin Hai asked.
"Okay." Ka'an said, "I don't think I need to introduce the concept of supercapacitor to you two. It is nothing more than a larger capacity than ordinary capacitors, which can reach a super large capacity of Farad level. This 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, supercapacitors have also developed rapidly. If I guessed correctly, there are already 1,000 Farad supercapacitors in the world."
"Your estimate is completely correct." Qin Hai interjected. The new supercapacitor just developed by a Japanese company a few months ago is of the 1,000 Farad level, but it is too bulky and is still far from practical.
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.
Capacitor is a very common component in ordinary electrical appliances. As the name suggests, it is a device that can store electrical energy. The unit for measuring the capacity of a capacitor is farad. 1/1 million farad is called 1 microfarad, and 1/1 millionth of a microfarad is called 1 microfarad.
Picofarads. Capacitors used in household appliances have a small capacity of only a few picofarads, and large capacitors have tens of thousands of microfarads, which are difficult to reach the level of farads. In addition, the size of electrolytic capacitors with tens of thousands of microfarads is the same as that of a section one.
The battery is similar. If the capacity were to be expanded a hundred times to several farads, its size would be conceivable.
The so-called supercapacitor precisely requires the capacity to be expanded to the farad level, and generally reaches several thousand farads or even larger. To make such a supercapacitor, it is obvious that we cannot simply rely on increasing the capacitor volume, but need to achieve it technically.
Innovation. Qin Hai himself had some ideas about supercapacitors, but they were far from enough, so he wanted to hear if the scientific madman in front of him had any better ideas.
Ka'an didn't know what Qin Hai was thinking. He just continued to talk according to his own ideas. He said: "According to my research, I think the key to supercapacitor lies in the selection of electrode materials. This material needs to have developed pores."
structure, high specific surface area, stable physical and chemical properties, in addition, it should also have low cost. According to the information I saw in the past few years, there are no more than three types of supercapacitor electrode materials currently used.
: Carbon materials, transition metal oxides and conductive polymers, the progress of supercapacitors depends entirely on the development of these three electrode materials."
"That's so good." Qin Hai couldn't help but clapped his hands, and then asked with a smile: "So, based on Mr. Ka'an's assumptions, 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 body mobility, good thermal and electrical conductivity, and a reasonable price, Mr. Kaan is interested in using it to develop an excellent ultrasonic material.
Is it a conductive capacitor?" 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 proven that its various physical and chemical properties meet the requirements you just put forward."
At this point, Qin Hai pushed another copy in front of Ka'an just in time. It was a detailed test report on graphene. The various data on it can be said to be clear to those who know the industry.
After Qin Hai developed graphene, the first application direction he thought of was the development of 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 feels that
Lacking a capable academic leader, he wanted to see if the Ka'an in front of him was a suitable candidate.
"It turns out that the world is changing so fast." Ka'an sighed again after reading the information Qin Hai gave him. With his eyes, he can naturally see the role of graphene in the development of supercapacitors. This material has been used for several years.
A few years ago, it was only in people's imagination, but now not only does it have detailed physical and chemical test data, but according to Qin Hai, industrial production has also been realized.
"I feel that I am so ridiculous." Ka'an said dejectedly, "If I had still stayed in school, maybe I wouldn't have missed these important inventions. Miss Serenity, 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 think it is meaningless for you to go back to that school now. They have refused to support you. If you go back, I am afraid you will only be on the bench. I
I think you have unique insights into 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 use graphene to develop supercapacitors?" Ka'an asked. Supercapacitors are also a relatively unconventional product. Although they have a wide range of applications, the technical difficulty is also very high, so there are very few companies.
Invest in this aspect. Hearing that Qin Hai wanted to develop supercapacitors, Ka'an was a little surprised, but also a little happy.
"Of course, and we are already doing this." Qin Hai replied.
"You... also plan 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 money in it in the future. But before that, I hope someone can conquer these two key technologies. The uses of supercapacitors are not limited to
Thunder and lightning collection, I think Mr. Kaan is very clear about this."
"Of course, this is a product with great commercial application prospects," Kaan 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 business cake in the future."
"Go to China?" Ka'an patted his head, and then laughed: "I have never thought about going to China to work in my lifetime, but it seems to be a good idea. If I nod, will I?
It’s time to call you my boss?”
"I would rather you call me a collaborator." Qin Hai said, stood up, solemnly extended his hand to Ka'an, and said, "I hope we can have a happy cooperation."
"Happy cooperation!" Ka'an also stood up, held Qin Hai's hand tightly, and said excitedly. (To be continued.)
