The headmaster is really powerful and domineering, and he starts to scare when he doesn't agree with him, and he also scares others so much that he can't speak.

And that's exactly what happened.

Why do you want to tell you about the progress of other people's research?

Even if it is really related to the national strategy, there are relevant people to consult and explore. To put it bluntly, you are an outsider, you are really not qualified!

At this moment, Lian Xuewen only felt that the anger in his heart was rising, what is not qualified to know? In the field of reverse osmosis method, especially in the field of polyamide materials, he has always been the leader in this, if the country wants to launch any project in this field, shouldn't he be the first person to find?

Not qualified yet? Joke!

Yes! Your rank is one level higher than mine! Academician! That's amazing!

Lian Xuewen was both envious and jealous, glanced at Liu Feng, and thought to himself that it was this kid, almost letting himself miss out on the academician, there was an 80% chance of being selected, and he was joined by this kid, and now it would be good to have a 20% chance!

Although Lian Xuewen was not angry with Liu Feng, he still did not have a seizure, but had a smile on his face.

It's just that if he doesn't have a seizure, he doesn't think that others will also have a seizure, and there are angry people who argue at the moment.

"Even the professor is just concerned and worried about the problem of choosing a route. If the task of the country catching up with and surpassing the world's advanced level is delayed, who will be able to afford it at that time? All of you here are the pillars of the country, and naturally there will be no leakers of secrets. ”

Someone next to him relieved Lian Xuewen.

Principal Tan frowned, he didn't even have long eyes, and was about to open his mouth to argue.

Liu Feng next to him spoke: "Actually, it doesn't hurt to tell you anything, anyway, with your scientific research speed, it's not very good." ”

Liu Feng instantly turned on the mode of 2B youth and began to laugh at the group.

"For example, I've experimented here with a method of oxidizing graphite to get a new material.

The specific method is that after the bulk graphite is treated with fuming concentrated acid solution, the graphene layer is oxidized into hydrophilic graphene oxide, and the spacing of the graphite layer is increased from 3.35A to 7~10A before oxidation, and then the separated graphene oxide sheet structure is easily formed by heating or ultrasonic peeling in water.

The results of XPS, infrared spectroscopy, solid nuclear magnetic resonance spectroscopy, etc., show that graphene oxide contains a large number of oxygen-containing functional groups, including hydroxyl group, epoxy functional group, carbonyl group, carboxyl group, etc.

The hydroxyl and epoxy functional groups are mainly located on the base surface of graphite, while the carbonyl and carboxyl groups are located at the edge of graphene. Therefore, after close contact with water, a nano-wide channel can be formed, which can form a filtering effect on seawater and realize seawater desalination.

Of course, the difficulty with this technology is that after oxidizing graphite, it is difficult to obtain pure graphene oxide, so it is difficult to separate this compound, obviously, in your case, this method is very difficult to achieve, let alone industrial production......"

In Principal Tan's stunned eyes, Liu Feng directly said a long list.

What's the matter with this kid, don't play cards according to the routine!

Moreover, what was told to them before co-authoring is only part of it?

Principal Tan said that he couldn't understand this kid at all.

On the rostrum, Zhou Lao and Zhang SHU Ji also got the surprise from each other's eyes, this kid, still have inventory?

It's just that now it's hard for them to find Liu Feng to continue talking, so the two had to look at each other and shake their heads, expressing helplessness.

As for the others, for Liu Feng's group ridicule, it is obvious that they were very dissatisfied at the beginning, and it can be said that the group is raging, but as Liu Feng's explanation continues to deepen, these people also began to gradually enter the state and listen carefully.

Zheng Xuemin, who had found fault with Liu Feng before, even looked around cautiously and took notes, but in that state, he completely looked like a thief.

After talking about graphene oxide, Liu Feng glanced around.

He found that the people around him and the people around him, even the guys who had scolded him before, were listening to him carefully, so he nodded with great satisfaction.

It's just that he secretly pouted in his heart, thinking to himself that a group of turtles, Lao Tzu's method has more ideas, and this little thing is nothing!

"In addition to the method of graphene oxide, there is another method for reference, and that is graphane.

That's right, at this time, a saturated hydrocarbon obtained by the reaction of graphene with hydrogen has a molecular formula (CH)n.

All the carbon is sp3 hybridized and forms a hexagonal network structure, and the hydrogen atoms are bonded to carbon from both ends of the graphene plane in an alternating form, which is interesting and can exhibit the properties of semiconductors.

Of course, the biggest disadvantage of this method is that it is not very controllable, because the hydrogen atoms are bonded to carbon in alternating forms, so its structure is very compact, resulting in too narrow pore size, which makes the passage rate of water molecules extremely low......"

Liu Feng even became more and more in shape, and finally became out of control.

"In addition to the above two methods to form graphene-like structure compounds, there is another method that can be considered on the basis of graphene.

Nitrogen-doped graphene or carbon nitride: that is, nitrogen atoms are introduced into the graphene lattice to become nitrogen-doped graphene, and the resulting nitrogen-doped graphene exhibits more superior properties than pure graphene.

This material is disordered, transparent, folded tulle-like, some flakes are layered together to form a multi-layer structure, showing a better pore size structure, and, more importantly, compared with the above two methods, this nitride graphene has an extremely excellent cycle service life, the average service life, almost 6~8 times that of polyamide composites!

Of course, these three are all based on graphene materials, so the price of each experiment is relatively expensive, and it is indeed not something that ordinary people can afford.

As for other graphene-like materials, I have also studied several of them, and I will tell you about one more ......"

"Ahem!"

Hearing Liu Feng tell the results of several new routes in a row, and now he has to continue to tell about it, Principal Tan coughed several times in a row.

He almost wanted to kill this loser!

You say that you have researched so many things, and it is okay not to publish papers, but no matter which one it is, it is better for you to continue to study deeply, even if you really can't produce any major results, but in the end it is good to brush up your reputation!

Is this kind of occasion a place where you can make a big splash?

"Headmaster, what's wrong with you? Not feeling well? If you don't finish the meeting, we'll accompany you to the doctor's appointment." ”

Liu Feng said with a kind look of concern.

Principal Tan: ......

Are you stupid!
