The assembly of the molecular sieve is realized by ion exchange technology, first put the molecular sieve into deionized water, then adjust the pH value to about 5, introduce cations, heat magnetic stirring for half an hour, and then filter, wash, dry, and roast in a muffle furnace for 2 hours.

After that, the pH value of the solution is controlled, and anions are introduced by oxygen oxidation to form nanoclusters.

The wait is always torturous, and in just a few minutes of the finished product, it feels like a century has passed.

At this time, in the container, the nano clusters that have been gradually formed condense but do not disperse, and the texture is uniform and colloidal.

Seeing this scene, Professor Li muttered in his heart, is this the real molecular sieve-based host and guest nanocomposite sunscreen?

He remembered the things he had made all day yesterday, and suddenly felt a hot pain on his face, he was really not as good as a junior undergraduate!

As soon as the end of the setting time arrived, Zhang Yi's experiment was completed.

Later, the finished product that had just been made was tested for ultraviolet absorption, and when the results came out, Professor Li and the others were taken aback.

Zhang Yi's finished product has greatly increased the absorption rate of ultraviolet rays, even more than ten times that of their previous research on nano-titanium dioxide.

Before that, if someone said that a sunscreen that could achieve an ultraviolet absorption rate of more than 95 percent, they would definitely be despised by them, and now Zhang Yi's finished product is in front of him, which also dispelled the doubts that Professor Li and several people have always had about Zhang Yi.

Zhang Yi's technology is indeed true!

This product, as soon as it comes out, will definitely cause a sensation and will have a great impact on the sunscreen whitening product market.

Lin Xiayu, who was originally careless and had the mentality of playing soy sauce, was also in a state of shock at this time.

This guy is a liar, a big liar! deliberately disguised as an ordinary college student, in fact, he is more powerful than a professor, and he actually understands such a high-end cutting-edge technology.

Lin Xiayu despised Zhang Yi again in his heart.

Ning Que hasn't come back to his senses yet, and his heart is also mixed, once upon a time, this was a classmate who was in the same classroom with himself, listening to the same teacher's lectures, eating in the same cafeteria with him, and going to the same toilet with himself.

Now that it has risen to an unattainable height, he can imagine that as soon as Zhang Yi's technology comes out, his status will be a qualitative leap in the future, and it will be a peak for people to look up to in scientific research.

In terms of this identity, Zhang Yi is no longer the classmate who usually jokes casually.

The most calm may be Ye Bin, who has never been in contact with Zhang Yi before, this experiment is in charge of the senior sister, he is just a starter, and he usually does what Lin Xiayu arranges him to do.

Therefore, for Zhang Yi, in addition to the shock caused by the inspection after the product was formed at the beginning, the biggest feeling is that this undergraduate disciple is actually a demon.

Seeing the reactions of Professor Li and several people, Zhang Yi thought that this had also achieved the expected effect, and the research and development of the product relied on the cooperation of the team, and it was obvious that he could not complete it by himself.

However, to complete the final project report, this is just the beginning, Zhang Yi reminded: "I just make the finished product, and next, we have to do characterization experiments, we need to adjust the finished product from a micro point of view, and finally optimize it, we still need to do a lot of work." ”

Professor Li let out a sigh of relief, his nervous mood gradually relaxed, and said, "What you said is easy to do, as long as the finished product comes out and is slowly optimized." ”

What Professor Li said also makes sense, as long as the finished product is passed, the rest will be easy to do, as long as the data is done to the best under the premise of reaching the standard, the task is completed.

Next, Professor Li arranged tasks for Lin Xiayu and several people, and Lin Xiayu also packed up his mentality and was full of enthusiasm, with Zhang Yi's successful experimental demonstration, which made Lin Xiayu have a lot of confidence in Zhang Yi's technology.

Ning Que and Ye Bin also started experiments according to Zhang Yi's demonstration method just now, and Zhang Yi followed Professor Li to his office.

"Haha, Zhang Yi, thank you so much this time, if you didn't provide a plan in time, I'm afraid this project would not be completed." As soon as the two sat down, Professor Li said to Zhang Yi with a smile, his tone was also full of neutrality, and his face recovered a lot, sweeping away the previous haze.

"Professor Li is welcome." Zhang Yi also knew that Professor Li was saying polite words, and each professor would always reserve an experimental plan for himself, and Professor Li would not be less.

"Zhang Yi, what kind of remuneration do you need for this technology?" Professor Li retracted his smile and asked tentatively.

Since Zhang Yi demonstrated the entire experimental operation, the final product effect was unexpectedly good, and the sincerity was very strong, Professor Li couldn't just take other people's technology and then act as if nothing had happened.

Finally getting to the point, Zhang Yi also became serious, and said calmly: "Professor Li, this technology is mine, okay?" ”

Unexpectedly, Zhang Yi was so cautious, Professor Li smiled: "Of course there is no problem, this technology is originally yours." ”

"Well, I want the patent right for this technology, and the first patent licensor must be me." Zhang Yi has his own considerations for obtaining patent rights, and China does not pay enough attention to patent rights, in fact, foreign countries have attached great importance to copyright.

Patents, don't look at the use of this thing now, it is not as refreshing as real money, but if it is used well, it is a priceless treasure.

"This ......" Professor Li pondered for a long time and said with a wry smile: "I want to explain to you about this, the school has clear regulations, all the invention patents of teachers in the school, the patent licensor belongs to the teacher, and the licensing unit belongs to the school, so if I apply for it, the licensor can only be me." ”

Professor Li didn't expect Zhang Yi to make this request, if he directly spent money to buy out Zhang Yi's technical rights, then Professor Li was not embarrassed at all, and paid directly, but he needed to apply for a patent, and the first authorized person was Zhang Yi, which was somewhat inconsistent with the rules of the school.

But it is indeed Zhang Yi's technology, which must be admitted, and it is not too much for people to make this request.

"I don't care about this, in short, I want the patent right." Zhang Yi has a deep understanding of the regulations on the licensor in the school, because he has been doing scientific research in the school since he started his master's degree and has been doing postdoctoral research, and he has also applied for many invention patents, and he also follows such regulations.

But.

Each professor has his own energy and relationships, but he is not an ordinary teaching teacher who seems to be an ordinary teacher on the surface, Zhang Yi, who has been engaged in scientific research for many years, has a deep experience.

Zhang Yi believes that Professor Li has a way to do this, and as for what the way, then he can't control it.

"Okay, I'll figure it out." There is no precedent for this situation, and Professor Li did not dare to give Zhang Yi a definite answer.

"Okay, then I'll wait for Professor Li's good news." Zhang Yi nodded.

After that, Zhang Yi and Professor Li discussed the details of the experiment again, and now the experiment is just at the beginning stage, and Zhang Yi will need continuous guidance until the completion of the project.

Zhang Yi calculated, based on his past experimental experience, this experiment would take almost two weeks to complete, that is to say, he would have to keep running to Professor Li's laboratory every day during these two weeks.

But at present, he still has a lot of time, and he usually doesn't attend much class, Professor Zhong's experiment has not started yet, and he knows the sulfuric acid residue experiment, in general, he still has a lot of time.

After agreeing, Zhang Yi left Professor Li's office.
