Li Ze flashed all kinds of ideas in his mind at this time, and then he was denied again, and there was no good explanation after thinking about it, just as he was about to find a reason to explain, the afterglow of his eyes swept to Zhang Yi on the side, who was walking over with a cat's waist, put a piece of paper on the rostrum and went back.

Seeing Zhang Yi coming, Li Ze didn't know what was going on, he picked up the paper and looked at it.

This is a page torn from the record book, on which are densely written about the problems mentioned by Fu Wenbin, and the problems that may be encountered again after connecting are all written.

After Li Ze saw it, the stone hanging in his heart finally fell to the ground, Zhang Yi saved his life, if he made such a sensational defense this time, but finally messed up, then it would be even more difficult for him to go further in his scientific research career.

Originally, he was just an ordinary professor in the materials industry, with no title and no fame, and the resources given by the state were originally few, so if he wanted to get more opportunities, he must have projects that he could handle, and in some fields, as long as he immediately thought of him when it came to domestic scientific research in this area, then he was half of the success.

Moreover, fame and resources are a virtuous circle, the more fame there are, the more resources, and the greater the chance of success after more resources, now Li Ze has chosen to put the treasure on Zhang Yi's technology on the road of development, and now it seems that there is nothing wrong.

Zhang Yi handed the note to the rostrum very quickly, and he was the identity of the secretary, the experts present did not think anything strange, Li Jianlin saw that Li Ze did not speak for a long time, and his head was covered with beads of sweat, who didn't know that he had encountered a problem and couldn't say it.

Li Jianlin said: "Academician Fu, we have encountered similar situations in the process of research, and details like this are indeed easy for people to ignore, and it is no wonder that Professor Li did not pay attention to it, I think many professors here will also have times when they do not pay attention in the research process." ”

Fan Yiming also echoed: "Yes, this variable has little impact on the experimental results, and it is indeed not easy to notice......

"You can't say that, the details are sometimes very elegant, a complete technology, no matter which detail should not be let go, otherwise how can you be sure that this factor will be the root cause of the experimental results?"

Although what Wang Muli said was reasonable, but before Fan Yiming finished speaking, he immediately refuted it, which had to remind people of Fan Yiming's words about Wang Muli just now, it seems that the two of them are going to be on the bar.

After Fu Wenbin finished asking the question, he put down the information in his hand and didn't care about other people's quarrels.

In fact, academic things, absolutely can not be a word, a person thinking about the problem sometimes will appear one-sided, many people discuss to complete the technology, Fu Wenbin all the way from an ordinary researcher to an academician, I don't know how many meetings and table debates have been experienced.

The literati debated no less intensely than in small wars, and sometimes they fought over a small issue, refused to give in to each other, and quarreled at the table, and even almost started a fight.

No matter how much you quarrel about technical issues, in terms of the final effect, it is indeed much better than thinking about the problem alone, Fu Wenbin also encourages young people to speak more, young people think actively, sometimes a casual idea, may become a breakthrough in technology.

But in the current situation, Fu Wenbin is a little disappointed.

This time, he came to participate in Li Ze's project defense, in addition to Lin Sihang looking for someone to entrust him, what attracted him more was the technology of this composite sunscreen project.

Since the implementation of the "Ninth Five-Year Plan" key scientific and technological research projects, the country has spent a lot of effort in order to make breakthroughs in high and new technologies, among which cosmetic materials as an important indicator of the future impact on the national economy, has been placed in an important position in material research.

In the past, the research on nano-scale particles has been affected by the reasons for spontaneous agglomeration, and the technology has been stagnant, and Li Ze's technological breakthrough can be defined by creating history.

It's just that since Fu Wenbin entered the conference room, he felt a little chilled when he saw the expressions of these experts who were active in the front line of the materials industry who didn't care about cosmetic materials.

In addition, he originally had high expectations for Li Ze, but he couldn't answer a simple question, and it seems that the level of scientific research is very limited.

Fu Wenbin shook his head silently in his heart.

Just as the faces of everyone present flashed with disappointment, anxiety, and schadenfreude, Li Ze suddenly said: "Actually, we have studied the issue of Academician Fu before, but I originally planned to study this content as a follow-up topic, so I didn't write it down in the information, since Academician Fu asked, then I will talk about it." ”

"The main reason why nanofilters can protect against the sun is that nanoparticles can absorb ultraviolet rays efficiently. But this is far from enough, in practical application, the sunscreen effect also depends on the dispersion of nanoparticles, if the nanoparticles are poorly dispersed, there will be a lot of gaps between the particles, so that even if the absorption of ultraviolet rays by nanoparticles is stronger, the sunscreen effect can not be reflected, because between the larger gaps, ultraviolet rays can be driven straight into. ”

"Academician Fu said that the change of grain size at the micron level affects its SPF value, and the technology we intend to use is to solve it by compounding, using nano titanium dioxide and Y-Fe compounding, so that smaller nanoparticles can be filled into the voids, and this distribution state can form a dense structure with small voids, and the dispersion effect of the powder in the dispersant is improved after compounding. ”

After Li Ze finished speaking, on the small blackboard on the wall of the conference room, he drew the molecular formula of the compound, the reaction process, and the corresponding experimental results.

The whole process proved that what Li Ze said could indeed completely solve the problem mentioned by Fu Wenbin.

After listening to Li Ze's introduction, everyone suddenly realized that it was not that Fu Wenbin's question was too difficult for Li Ze to answer, but that he wanted to take this as a follow-up research content and then apply for the project.

Usually after a project is completed, there is also a technical outlook, the purpose is to continue the in-depth research of the topic, and experts can use this prospect to apply for scientific research funds, so that they can get a research grant.

Ning Que also pinched a handful of sweat, and at this time he was also relieved, and said to Lin Xiayu: "Senior sister, it seems that what you said is right, our professor has not experienced any storms, this defense professor is fine, but it scares me a lot." ”

Lin Xiayu didn't have such a glass heart as Ning Que, she had obviously noticed Zhang Yi leaning over to the rostrum just now, and guessed in her heart that Zhang Yi must have helped Professor Li, this guy is really powerful and understands everything.
