When he came to the door of the head teacher's office, he knocked on the door.

"Come in. Sure enough, the familiar voice of the head teacher came from inside.

When I opened the door and walked in, I found that the head teacher was packing up and seemed to be about to leave the office.

Seeing this situation, Shang Yiyun was a little lucky, he came too coincidentally, if he came late for a while, his homeroom teacher would have left the office a long time ago, so it was better to come early than to come by coincidence.

After explaining his intention to the head teacher, he took out the leave slip, and his head teacher signed it.

For Shang Yiyun, a student, his homeroom teacher is also very helpless, obviously a champion in liberal arts, but now he has done many things that the champion in science can't do, but Shang Yiyun has always been a student at the School of Philosophy of Kyoto University, but this cannot be changed.

After getting the leave slip, Shang Yiyun said goodbye to the head teacher, and just now he saw that the head teacher was trying to go out and leave, so he didn't want to continue to bother the other party now.

After leaving, he returned directly to the dormitory, handed the leave slip to Shen Fengyu, and gave the leave slip to the teacher during class.

After everything was done, Shang Yiyun returned to the laboratory, and from now until the arrival of the rest of the team, he was ready to observe the materials on the test bench all the time.

When he came to the laboratory again, he found that there was no one else in the laboratory, which was good enough to allow him to have a quiet environment.

When he used the instrument to observe the changes of the materials on the laboratory bench, he made a major discovery, the materials on the laboratory bench are slowly self-healing, and now they are self-healing 1/6, and the calculation time is only half an hour, so it may take three hours to self-repair.

Every once in a while, Shang Yiyun observes the progress of material healing, but finds that the speed of self-repair is getting slower and slower, an hour and a half has passed, and the material has self-repaired 1/3, looking at the current situation, when the other members of the team arrive, the material will self-repair at most 1/2.

However, it is already a relatively big breakthrough to be able to reach this level now, and the process of making a material from scratch is not something that can be completed in a short period of time, and he knows it very well in his heart.

In this way, time passed slowly, and during this time, there were more and more people in the laboratory, but there were very few other members of the team, only a few people, and when they left in the morning, Shang Yiyun said to them that they should come to the laboratory before two o'clock in the afternoon.

It was still 20 minutes before two o'clock, so he was not surprised at all by the current situation.

In the next 20 minutes, most of the other members of the team arrived, but some of them could not be here for various reasons, and they all explained their reasons to him.

For this situation, Shang Yiyun did not force them to come to the laboratory, after all, everyone has their own things to do, and now they are just observing the repair of materials, and the number of people does not need to be too many.

After a while, Shang Yiyun observed the materials again and found that the progress of the repair had become slower, and looking at this situation, it seemed that the final repair result could only be known in the evening.

The waiting time is the most boring, during this time, Shang Yiyun went to the library to borrow a few books, while reading the books and observing, the books borrowed are all related to new energy, and in an afternoon, he learned a lot of things.

"The material restoration is complete. ”

At this time, Shang Yiyun suddenly heard a familiar voice, and his voice was full of excitement.

When Shang Yiyun heard what the other party said, he was stunned for a moment, but he quickly reacted, and hurriedly walked to the experimental table, looking at the materials that had been repaired, and said that it was not easy.

After nearly seven hours of waiting, the material was finally repaired, because the material is composed of a malleable polymer and an ionic salt, which forms a special adhesive force, also known as ionic dipole interaction, which is a force that exists between charged ions and polar molecules.

This means that when the material cracks or is scratched, the charged ions and polar molecules in the material attract each other to achieve the purpose of repair.

At this time, although the experiment was preliminarily completed, Shang Yiyun was not satisfied, because the repair of the material was completed in a special environment, so this material can only be regarded as a semi-finished product.

The research is considered successful if the smartphone screen material can be repaired at room temperature.

Now the experiment can only be regarded as a big breakthrough, but there is still a long way to go to success, and the biggest problem now is how to make the material can be repaired at room temperature.

As long as this problem can be solved, the research on the material that can repair the smartphone screen will not be far from success, but this problem is difficult for many people, otherwise this material would have been studied a long time ago.

This kind of thing is not in a hurry, it is a happy thing that there is a breakthrough in today's research, and there are still a few members of the team who don't know about it, so he posted the results to the chat group.

The few members who did not arrive have left the diving state.

"Wow, it's a shame that I didn't show up for such an important situation!"

"Alas, this afternoon, I was going to conduct another research project with my supervisor, so I didn't come. ”

……

Hearing the words of these members, Shang Yiyun replied.

"This experiment has only made some progress, but it has not been successful, and when the experiment is really successful, it will not be a pity that you will not be absent. ”

As soon as I posted these words on my phone, I don't know which member started it, and a sentence appeared in the chat group.

"Received, promise not to be absent next time. ”

"Received, promise not to be absent next time. ”

……

In this way, the repeater mode was turned on in the chat group, and there were more than ten more messages in an instant.

Shang Yiyun did not reply to this situation, but after packing up the things on the experimental table, he left the laboratory with the rest of the team.

It is almost impossible to make a breakthrough in the experiment in a short period of time, so he plans to go to the library to absorb some knowledge and lay a solid foundation for the next step of research.

Now that the summer vacation is not far away, he is ready to register and grow the company during the summer vacation.

Of course, the premise of all this is to be able to have breakthrough research in new energy, otherwise it will be difficult for the company to develop and grow without superior products.

Moreover, the company's management personnel are not yet in place, and he has also told the other party about this before, but the other party is still in the consideration stage, after all, the company has not been established, which is really unreassuring.

Before I knew it, I had arrived at the library, and when I was about to enter, my mobile phone rang suddenly.
