"Lin Xiayu!" Professor Li glared at the girl, but Professor Li, who was familiar with the girl's temper, didn't say much.

Lin Xiayu didn't raise his head at this time, but just glanced at Zhang Yi when he first entered the door.

He is in his early sevens at one meter, with an ordinary white T-shirt and slacks, and a pair of white-washed canvas shoes.

The appearance is also average, and it has nothing to do with handsomeness, except for the white skin, there is no other advantage.

It looks like an ordinary undergraduate, almost the same as Ning Que, the junior brother of the undergraduate.

Lin Xiayu was quite disappointed after taking a look, she couldn't find a way out of this topic, and what ability did an ordinary undergraduate have, the professor was afraid that he would be in a hurry, and even Zhang Yi would be regarded as a life-saving straw.

At this time, there was some quiet in the office, it may be that Ning Que had already reported Zhang Yi's situation just now, so as soon as Zhang Yi said just now, there was no imaginary sensation, except for Lin Xiayu's reaction.

"Xiao Zhang, can you tell us your plan in detail. Although Professor Li showed a kind smile on his face, he still didn't believe it in his heart, but he was a professor, even if he didn't believe it, he wouldn't show it directly like Lin Xiayu.

And the current situation of the project is not optimistic, the 15th of next month is the date of the final defense of the project, if the defense can not pass, the failure of the project is a trivial matter, and the reputation that he has managed to operate over the years can be smashed in his hands.

After Ning Que reported to him, the reason why Li Ze decided to talk to Zhang Yi face-to-face was not because he thought that Zhang Yi would really have a solution, thinking that he had not been able to solve this problem after many years of research in materials, what could a junior understand about it?

However, the two problems that Zhang Yi said are indeed the problems encountered in this project, and Zhang Yi can say that the key to the problem is that he must have an understanding of this project.

Even if it is not Zhang Yi himself who says the problem, but there is a more talented person behind Zhang Yi, since that person can contact him with the help of Ning Que, it is possible to really master this technology, and first see what Zhang Yi can do, or what requirements he can make, as long as he can solve the problem, a little sacrifice is not hesitated.

In short, it is better to believe 10,000 than to miss a chance!

Zhang Yi didn't expect Professor Li to think so much, he thought very simply, since he came, let's get straight to the point and explain the problem clearly. In the end, this technology will definitely become a bargaining chip, and Zhang Yi has no intention of working for others in vain.

What Zhang Yi has to do now is to restore this technology, so he said: "I don't know if Professor Li has ever heard of molecular sieves. ”

"Molecular sieve?" Professor Li frowned, thought for a moment and said, "I seem to have heard of this, but as far as I know, this seems to be a technology applied to petroleum. ”

"Yes, at the beginning, it was applied to petroleum, but now Western countries have applied it to materials, chemicals, biology and other industries, and have achieved good results. Zhang Yi said lightly.

Professor Li wondered: "However, there are no reports on the application of molecular sieves in materials. ”

"Don't be a liar. Lin Xiayu still scratched on the notebook, but this time he spoke much louder, obviously not giving Zhang Yi any face.

Professor Li did not speak out again to stop Lin Xiayu.

Well, Zhang Yi was stunned again, Western countries have indeed made breakthroughs in the application of molecular sieves to materials, but there are really few reports, in 98 years this technology is still very advanced, people have developed it and left it for their own use, and there is no technical output, until the rapid development of technology, the technology of that year was slowly unlocked.

At present, the exchange of information around the world is not smooth, and many advanced technologies cannot be published in a timely manner, or even unknown to the public. It seems that Zhang Yi can only be a pioneer of technological innovation.

"Ahem. Zhang Yi coughed lightly twice, and said loudly: "I mean, molecular sieves have been successful in materials, but you don't know, the application of molecular sieves can easily solve your sunscreen problems." ”

"Oh, Xiao Zhang, can you say more carefully. Professor Li also thinks that Zhang Yi is a bit nonsense, but don't blindly put the material on the material when you see a molecular sieve in a foreign newspaper.

"Hmph! big liar!" Lin Xiayu still lowered his head and drew something on the notebook.

Zhang Yi directly ignored Lin Xiayu and continued to analyze: "I told Ning Que before that there are two problems with nano titanium dioxide as a sunscreen, one is that the surface polar nanoparticles are easy to agglomerate, and the other is that the photocatalytic effect causes irreversible damage to the skin, which you have confirmed in the experiment, right?"

Everyone present, except for Lin Xiayu, nodded.

"Then can we think differently, Professor Li, can you give me a pen and paper?" Zhang Yi suddenly asked.

As soon as Zhang Yi spoke, the eyes of several people were aimed at Lin Xiayu at the same time.

Lin Xiayu was stunned for a moment, and the movement of drawing a notebook in her hand also stopped, knowing that everyone was staring at the pen and notebook in her hand, and then glared at Zhang Yi fiercely.

Zhang Yi and Lin Xiayu were a little close, and there seemed to be a faint fragrance wafting in the air, Zhang Yi rubbed his nose and muttered in a low voice: "Uh-huh, rose fragrance." ”

"Big liar, what are you talking about?" Lin Xiayu said in a very bad tone, but this time she finally raised her head, and suddenly let Zhang Yi see her face clearly, although she cut her hair short, she looked delicate, giving people a heroic feeling.

It's just that Zhang Yi is a little embarrassed, holding the grass, this can be heard!

Is this woman a rabbit?

"Here you go!" Lin Xiayu snapped the notebook shut, picked up the notebook and smashed it at Zhang Yi, but the movement was not big, and it happened to be thrown into Zhang Yi's arms.

Zhang Yi picked up the notebook and opened it to take a look, except for some dense scratches, there was no ink stained inside, it seems that this kid is not stupid.

After taking the pen, Zhang Yi drew in the blank space of the notebook.

Seeing Zhang Yi's movements, Ning Que asked beside him, "Zhang Yi, what are you painting?"

Professor Li saw the mystery at a glance and said, "This is the structural diagram of the molecular sieve that Zhang Yi said. ”

Looking at Zhang Yi's drawing of the molecular structure diagram on the notebook one by one, as well as his determined appearance, Professor Li suddenly felt that the junior student in front of him seemed to be really a little unsimple, although he didn't quite understand what Zhang Yi was going to do, but it seemed that he would never simply draw a few drawings to deceive him.

After drawing for a while, Zhang Yi finally stopped, showed the drawn diagram in front of several people, and said: "Molecular sieve is a kind of porous aluminosilicate, and its pore system is formed by the spatial orderly arrangement of atoms, and the shapes are uniformly ordered. ”

"In the preparation of nanoclusters, this pore system acts like a naturally occurring micro-reactor in which the nanoclusters are formed and arranged in an orderly manner according to the spatial arrangement of the reactors. This can be done by using the pore template action of molecular sieves. ”

"Therefore, we can divide the subject and guest to assemble the molecular sieve and nano titanium dioxide, the main body is our molecular sieve, and the object is nano titanium dioxide, so that we can solve the two problems mentioned before. ”

"So amazing?" Ning Que said in surprise.

"Yes, it's that amazing. Zhang Yi smiled faintly: "The name of the technology I am talking about is called, molecular sieve-based host and guest nanocomposite sunscreen." ”

"Molecular sieve-based host and guest nanocomposite sunscreens?" Professor Li said several times.

Professor Li was thinking about it as Zhang Yi spoke, and he didn't pay much attention to it at first, but the more he listened to it, the more shocked he became.

It turns out that thinking in a different direction can have such unexpected results.

Nano titanium dioxide has all kinds of drawbacks, if you can make a molecular sieve to assemble these nano titanium dioxide and turn it into a new thing, won't you be able to overcome the defects of nano titanium dioxide itself?

Just like to measure the volume of a light bulb, the first thing many people think of is to divide the bulb into circular parts, cylindrical parts, arc parts, etc., and then use calculus to calculate them.

As everyone knows, thinking in a different direction, you only need to fill the bulb with water, and then pour the water into the graduated cylinder to directly get the volume of the bulb, the method is very simple, but many people can't think of it due to the influence of inertial thinking.

If this student really came up with it himself, it would be too clever! There is such a way to simplify such a delicate thing.

If this method is feasible, it is really possible to complete this technology in a short period of time, which is really a great favor for him.

Even Lin Xiayu, who was silent, turned her head and glanced at the structural diagram that Zhang Yi was holding in her hand, but she still firmly believed that Zhang Yi was pretending to be a ghost, so she turned her head after just a glance.

"Good, good, good molecular sieve-based host and guest nanocomposite sunscreen. After Professor Li figured it out, he said three in a row, oh no, four is good, both eyes are about to burst out of sparks, and asked Zhang Yi excitedly: "Xiao Zhang, how sure are you that this technology can be made, and what is the effect?"

Knowing that Professor Li's concern was whether the experiment could be successful in a short period of time, Zhang Yi nodded and gave a definite answer: "100% sure, the effect is excellent, and as long as the equipment is complete, I can complete it in a very short time." ”

"No, I'm against it. Just as everyone was still immersed in the shock brought by Zhang Yi, Lin Xiayu stood up violently.

Although I can't understand what Zhang Yi painted, it sounds like what Zhang Yi said also makes some sense, but Lin Xiayu has always been in charge of the previous experiment, and after the last pre-defense, he had already held a meeting to say that he would optimize the project.

"Professor, we don't have time, now the optimization project has been launched, the experimental links are more refined, and the requirements cannot be met before they are tasted, if they are replaced by other methods, the risk of failure will be great......" Lin Xiayu's tone was a little cold, now what she is most afraid of is to make extraneous branches, and to engage in other things, and finally it is not possible to try and probe again, not only a waste of time, but also make the original optimization plan unable to be implemented.

"Okay, I got that. Professor Li didn't let Lin Xiayu finish speaking, but turned his head to look at Zhang Yi and said, "Xiao Zhang, when do you think the experiment can be carried out?"

Zhang Yi thought about the time arrangement, today and Thursday, except for going to Professor Zhong Qiang's office tomorrow morning, and Saturday to make time to find partners for the sulfuric acid slag project, there is no arrangement on Sunday, "In this way, I have time on Sunday, and I can do experiments with you when the time comes." ”

"Okay, then do as you say. Professor Li directly made a decision, this is an opportunity for technological innovation, and his sense of smell is comparable to Lin Xiayu.
