The gift was put aside, Ji Donglai hurriedly took out the graphene electrode from his personal pocket and handed it to the professor, the old professor took it in his hand and glanced at the sunlight, and immediately picked up the magnifying glass at hand to take a closer look.

I couldn't see it clearly, so I immediately took it to the microscope at home and took a closer look.

"Graphene, you made a graphene electrode?"

Looking at the neat graphite crystals under the microscope, Professor Tu turned his head in surprise, his eyes full of shock.

This thing is now a problem all over the world, and large companies in many countries are also investing, and few people are succeeding.

"Not only has it been successfully developed, but I have also made a finished product, which is preparing to be used in drones. Once successful, my drone will be able to fly directly from here to Seoul, and if it is deployed in Sansha City, Hainan, the radiation range will be able to reach the whole boy. ”

"Taking off from Zhejiang can cover the entire territory of Guam, and starting from Fujian can easily complete a precision strike on the surrounding 1,000 kilometers, which is worth the effort over the years."

Looking at Professor Tu's expression, Ji Donglai knew that the other party was shocked by the news.

As an expert in materials, Professor Tu has been concerned about the development of high-tech in the field of materials at home and abroad all the time in recent years. Graphene has been hyped up very much over the years, and Professor Tu's subordinates are also making related attempts, all of which are too costly.

What material to use as an attachment to make graphene attach to this difficult problem, the professor has not made a breakthrough, and it is impossible to make graphene grow regularly without a suitable preparation carrier.

Any substance is a three-dimensional structure, and even graphene, which is called a planar structure, can grow along the three-dimensional structure. If it is not a chain-like structure, it will grow into a three-dimensional structure, and then the dielectric constant will change.

In order to store a large amount of energy, a regular arrangement is a necessary condition, such as thorium, uranium, rhodium, which contain huge amounts of energy, and there is no abnormal irregular arrangement.

Once the structure changes, energy storage will not be realized, and Professor Tu also tried his own experience over the years, but ultimately failed.

Now that Ji Donglai has achieved it, his youngest student has actually achieved it, and in fact, he has achieved it himself. It's just that the other side is also a team, and not doing it alone, which is very good.

Cultivating a scientist can only achieve one discipline, and cultivating a leading scientist is not just a discipline, and the whole nation and even all mankind can benefit.

"How much did it cost to do this?"

Taking off his glasses, Professor Tu carefully inspected this crystal, just like Ji Donglai when he first saw this thing, he couldn't put it down, and he didn't dare to put it down or touch it.

"I spend 200,000 yuan a day in this department, but in fact, I can't support it without 400,000 yuan a day. This is not counting the salaries and bonuses of the personnel, plus the resources borrowed from various places, at least 600,000 yuan per day. ”

"Now it seems to be worth it, this is a by-product of our experiment, the main business of this department is not to do this, and then because of a certain technology breakthrough. Our UAV has a high demand for high-energy batteries, and the project leader came up with a whim, combined the four technologies, and then successfully prepared this. ”

"This is also a windfall for us, but unfortunately we can't reach the scale of production at the industrial level, only on the scale of the laboratory. In the next step, we will strive to complete industrial-level production, Tu Lao, if you are interested, I will ask the person in charge of the laboratory to come in a few days, I do not plan to convert this technology for civilian use for the time being, you can share it here. ”

As a business leader, Ji Donglai is very grateful to Polytechnic University, and he has been weathered all these years.

As long as Ji Donglai's company needs any support, the teacher or Professor Tu will spare no effort to support, and there will never be any complaints.

Now that there is a breakthrough in technology, Ji Donglai didn't dare to say that this was the contribution of his own company, so he decisively put forward the meaning of sharing with Tu Lao.

"Good boy, good! There are too few people with a mind like you these days, don't worry, I understand the whole process, you are very good! ”

Hearing that Ji Donglai was able to share his technology with his school, Professor Tu was very pleased.

In the era of the road and the hurry, entrepreneurs and businessmen pay attention to the supremacy of interests, and there are too few people who can miss their alma mater and never forget their roots. Ji Donglai's sale of this technology is also a sky-high price, especially some large foreign companies, always staring at domestic high-tech technology.

No matter which country has now focused on energy storage technology, Japan and South Korea are hydrogen energy batteries, and China and the United States are electric vehicles.

Everyone knows that a new industrial revolution is brewing, and whoever wants to break through will be able to gain the initiative.

Ji Donglai has completed a breakthrough in this set of technologies in China, which is very rare.

This meal is the most delicious one Professor Tu has eaten in these years, and it is pleasing to the eye no matter how you look at Ji Donglai. Teacher Yu was even more relieved that his most proud student was also the most proud student of his teacher, which meant that his vision was correct.

Professor Tu specially drank a glass of wine today, and gave Ji Donglai the contact information of everyone present, which is too big.

There is a random person who is called out to give a lecture in society for 30 minutes, and there is no one who charges less than 500,000 yuan.

Some people drink here, and the projects that their students do are all at the level of tens of millions. A so-called small technological innovation can actually be worth 18 million yuan.

Officially with Professor Tu's platform, Ji Donglai had the opportunity to sit and eat with these people. The top academic leaders of Huazhong University of Science and Technology, National Defense Science and Technology University, Harbin Institute of Technology, and Western University of Technology are all here.

Including Mr. Yu's son-in-law, who did not appear here, is also a professor at the Massachusetts Institute of Technology.

There is a good saying, in the second half of the great voyage, there are many people with imperial qualifications, and now Ji Donglai is in this situation.

It is this simple solid wood square table, an old house in the style of the last century, that can determine the direction of a country's technology in a conversation and laughter.

After eating, Ji Donglai simply distributed the gifts he brought to a few senior brothers, Professor Tu only left a box of cordyceps, and the rest of Ji Donglai gave all his brains to his homeroom teacher, Teacher Yu.

"Come east, I'm going abroad to take care of my granddaughter for my children in the future, and you can only call if you have something. Senior Brother Liu of USTC is a very powerful person, he was my guide back then, and you can find Senior Brother Liu if you really encounter something that can't be solved. ”

"Professor Tu is old, in case there is a mistake, you have to know who to look for. The further you go back to Vietnam, the more you will have to rely on yourself when I go abroad. ”

Downstairs in the family, Ji Donglai opened the car door for Mr. Yu, and Mr. Yu said earnestly, Ji Donglai only knew that Mr. Yu was going abroad, and his heart was greatly moved at the same time.

Over the years, Mr. Yu will come forward for anything that involves coordination, which is why Ji Donglai is so proficient in Polytechnic University.

Without Mr. Yu, many problems are actually not easy to handle, and today's birthday for Professor Tu is actually Mr. Yu paving the way for Ji Dong before his departure.

"Thank you, teacher, I will definitely live up to the teacher's expectations, I really can't persevere, when the teacher introduces me to a school, I will teach."

Both of them are understanding people, and they both know what they are saying to each other, Ji Donglai took out a shawl from the trunk for the teacher, which was hand-woven by Afu Khan.

Teacher Yu didn't say much, he went upstairs with two things, and Ji Donglai returned to Yiyuan Manufacturing by himself.
