Meng Maoleng paused for a moment, then shook his head, "I'm afraid there is no equipment in the institute that Teacher Chu said." ”

Chu Hao rubbed his nose, this time it was embarrassing, although the redox method is relatively simple, but the most basic chemical equipment must be there, and the research institute is the Institute of Metal Materials, which means that all the people in the institute are physical materials scientists, so naturally there is no such chemical equipment.

Chu Hao said: "Yes, I'll give Shi Lao a call to see if he can coordinate it, borrow a laboratory and come over, anyway, I'll use it for the time being, and we'll add it ourselves when we get back." ”

Director Zhu gasped and added himself?

Chu Hao's hand seems to be a little too big.

Although it is not like before, in the bitter era, a pair of gloves had to be washed repeatedly, but it is not enough to say that it is rich enough to add another set of chemical equipment.

If the simplest chemistry laboratory is the kind of elementary and middle school, tens of thousands of yuan will be stopped, but Chu Hao will definitely not say that he needs to use such simple equipment.

Lai Hao Tian Tian, I'm afraid that millions of dollars will be spent, maybe 10 million will not be able to stop.

However, the most important thing is that Chu Hao may not be able to use that equipment a few times, after all, he mainly studies metal materials and physics, maybe he will use it when he decomposes graphene, and the rest of the time, he will put it there.

In contrast, Meng Mao was indifferent for a long time, and after a little surprise, it didn't matter.

After all, Shi Lao said that at least one or two hundred million funds should be given to Chu Hao for the next project.

And said so, but in fact, everyone knows that this is just compensation for Chu Hao's research on the graphene project, after all, the country can't think about winning a Nobel Prize for nothing, and it is right to say anything.

Therefore, Chu Hao can spend this money as much as he wants, as long as it is not blatantly put in his pocket, no one will say anything.

If you really want to put it in your pocket, you can secretly do it, and you know that you can open some invoices and put it in your own pocket.

After all, how many people can't study the fart, it's okay to put it in their pockets, Chu Hao is such a big hero, and the flowers will be spent.

There are so many of these things in the scientific community.

And Chu Hao also called Shi Lao on the side, then turned his head and said, "I have communicated with Shi Lao, and he will help borrow a laboratory." ”

After a while, Shi Lao walked over with Professor Lei.

"I have already talked to Director Fu of the Institute of Chemistry, and he agreed that we should go to his place to do an experiment. Shi Lao said.

Then Shi Lao said hello to Director Zhu again, they are both studying materials, and they have known each other for decades.

Professor Lei looked Chu Hao up and down on the side, his expression a little inexplicable.

Chu Hao's speed is really too fast, this has just decomposed graphene, and he has actually studied the small-scale decomposition technology of graphene.

Although it is a little strange, how did Chu Hao develop the graphene decomposition technology without the support of any experimental equipment?

Could it be that Chu Hao is still proficient in theoretical chemistry?

Otherwise, I really can't explain how Chu Hao developed the small-scale decomposition technology of graphene.

However, he was convinced that Chu Hao had developed a small-scale decomposition technology, because when he decomposed graphene before, Chu Hao had not done any experiments, and it was all directly from empty white teeth.

Really, no matter what kind of thing Chu Hao does now, he is not surprised.

Let Meng Mao call Yin Yulian, Chu Hao and his party walked directly towards the Institute of Chemistry.

Although metal materials science and chemistry have nothing to do with each other, Shi Lao has been in the Academy of Sciences for so many years, and he is no stranger to the people in the Institute of Chemistry, so he directly took Chu Hao and them to the director's office.

Chu Hao looked at the position number at the door, and a playful smile flashed on the corner of his mouth.

It turns out that this director Fu is the director, the person surnamed Fu, being the leader, it's a real loss, I don't know, I thought it was a deputy director.

After entering the door, Shi Laozheng was greeting a middle-aged man in his fifties.

"Shi Lao, can you tell me what experiments you are going to do, and I will let people prepare the equipment and materials. Director Fu said with a smile.

"Do small-scale graphene decomposition experiments, equipment or something, it seems that there is nothing special, Chu Hao, tell me, what equipment and materials do you want." ”

After speaking, Shi Lao beckoned to Chu Hao.

And Director Fu on the side looked at Chu Hao in disbelief.

Chu Hao researched the graphene decomposition technology, he naturally knew, but wasn't it torn off with tape, how could Chu Hao say that he was going to use chemical methods now.

Moreover, hasn't Chu Hao always studied materials science and physics, how could he suddenly even know chemistry?

In addition, Chu Hao's progress seems to be a little too fast.

You must know that the initial technology is not to be matured, and it needs to be studied step by step to make it perfect.

Otherwise, it's just a scientist, and what kind of engineer do you need?

To put it simply, scientists are responsible for finding ways to develop a technology, while engineers are responsible for making it simpler, simpler, cheaper, and faster to use.

According to his experience, it is impossible to go from the first discovery to small-scale production in two or three years.

And Chu Hao has only been for a long time, not even two months.

Moreover, if Chu Hao really researched the small-scale graphene decomposition technology, his attainments in chemistry would not be compared with him, and he would probably not be weaker than any qualified professor-level scholar, he really didn't know how Chu Hao's head grew and how he could do so many things.

Hearing Shi Lao call him, Chu Hao said directly: "Director Fu, don't be too troublesome, it's redox method, what you want are ordinary things, sodium nitrate, concentrated sulfuric acid, potassium permanganate, these things, it's a little troublesome in the water bath, but it should be all there." ”

Director Fu nodded, it is true that they are all common chemical elements, not to mention a national research institute like the Institute of Chemistry of the University of the Academy of Sciences, that is, any high school that is not too bad has these things, and it is also as Chu Hao said, the water bath is a little troublesome, at least it must be the research institute of the university to have it.

Director Fu led Chu Hao and them directly to an idle chemistry experiment table.

The other researchers, who were originally busy around, couldn't help but whisper when they saw a group of people like Chu Hao coming.

You must know that Chu Hao is a recent figure in the University of Science and Sciences, and even in the entire Chinese scientific research community, and he is not one of them, how can they not know him.

Originally, Chu Hao became the deputy director of the Institute of Metal Materials, which was quite unacceptable to some people, but later Shi Lao drove Professor Hu and them away for Chu Hao's sake, which aggravated the dissatisfaction of some people.

But after Chu Hao researched the graphene decomposition technology, all the noise disappeared without a trace.

There is no way, the scientific research community is like this, speaking with results, whoever has the highest results, who speaks the loudest.

Now if Chu Hao is the top scientist in China, no one dares to deny this.

And now, Chu Hao actually came to the Institute of Chemistry, and it seemed that he was going to do an experiment, which made them not curious.

Chu Hao said to Yin Yulian: "You can do the experiment later, no problem, right?"

Yin Yulian paused for a moment, and her heart chuckled suddenly, although she was from a chemistry background, she hadn't touched a chemistry experiment for two or three months.

In addition, this is still a small-scale graphene decomposition technology, not to mention that she has not done it, no one in the world has done it, she is really under pressure, but fortunately, she has already done a graphene experiment on stage, although she is a little panicked, but Yin Yulian still nodded.

"Start with two grams of graphite powder. Chu Hao said suddenly.

Yin Yulian walked to the chemistry experiment table, took a deep breath, looked at the materials of the bottles and cans on the experiment table, and suddenly had a familiar feeling, and her heart suddenly calmed down a lot.

He took out a bottle labeled graphite powder and weighed two grams of graphene on the scale.

"Put the graphite powder into a beaker of two hundred and fifty milliliters, and then pour one gram of sodium nitrate. ”

Then slowly add 46 milliliters of concentrated sulfuric acid and stir well. ”

With Chu Hao's guidance, Yin Yulian started the experiment step by step in an orderly manner.

Under her agitation, the potassium permanganate in the concentrated sulfuric acid and the graphite powder were oxidized to form a brown color. There are derivatized carboxylic acid groups at the edges and graphite flakes with mainly phenolic hydroxyl and epoxy groups on the plane.

Seeing that Yin Yulian had gradually entered the best situation, Chu Hao did not stop, and on the other side, he directly picked out a bunch of chemical reagents and began to make reducing agents.

In the redox method, the reducing agent is the most critical thing, and graphene cannot be used with ordinary reducing agents, otherwise there will be defective graphene.

The incomplete graphene can only be made into some photocells, MOS tubes and the like, which can still play a certain role in the field of materials and electronics, but there is no need to think about supercapacitors and foldable screens, and the research value is greatly reduced.

At this time, everyone's eyes were focused on Chu Hao, Yin Yulian was originally a person from their chemical research institute, and they were no strangers to it, so Chu Hao asked Yin Yulian to do the experiment, they were not surprised at all.

It can even be said that Chu Hao can't do chemical experiments, so it should be correct.

But watching Chu Hao skillfully pour in all kinds of reagents and materials, everyone's eyes moved, it seems that Chu Hao really knows how to do chemical experiments and wants to be skilled.

Moreover, Chu Hao should still be the most critical reducing agent, and the reducing agent in the redox method is the most important, once something goes wrong, everything will be over.

Chu Hao glanced at Yin Yulian's side, "Prepare a water bath, slowly add six grams of potassium permanganate while stirring, and be careful not to exceed 20 °C." ”

Yin Yulian was about to take the water bath.

Suddenly, a man from the Institute of Chemistry rushed out of the side and pushed a water bath filled with ice cubes.

The water bath is mainly used for distillation, drying, concentration, and warming chemicals or biological products in the laboratory, and can also be used for constant temperature heating and other temperature tests, and is an essential tool for biology, genetics, viruses, aquatic products, environmental protection, medicine, health, laboratory, and analysis room.

The low-temperature sink of the water bath is equipped with a circulating pump, which can lead the tank to the constant temperature liquid to establish a second constant temperature field, and can also be used as a cold source to lead the refrigerated liquid in the tank to the experimental container outside the machine.

Generally speaking, the working temperature of the water bath can reach -30°C~100°C.

"Senior Sister Yin, you can use this water bath, the inside is all clean. ”

Yin Yulian glanced at the man, said thank you, and pushed the water bath over.

And Meng Mao, who was on the side, looked at the man with a look in his eyes that was suddenly a little wrong, and even a little murderous.

The man glanced at Meng Mao, sneered and walked away.

The chest of the angry Meng Mao fell together.

However, it is useless for him to be angry, who made him not to use the water bath.

After five minutes, the beaker is taken out of the water bath to complete the low-temperature blending phase. ”

After speaking, Chu Hao glanced at Meng Mao, and couldn't help but feel a little funny, this hasn't even clarified the relationship, he is angry like this, if this is really something, what happened just now, wouldn't it be to blow up his lungs.

"Meng Mao, don't be stunned, make a record of the experiment, I don't have time to guide you on the side. ”

Meng Mao glared at the man before him angrily, and reluctantly picked up the experiment record.

"After the beaker is heated to 35°C, hold it for 30 minutes and wait for the reaction. Chu Hao said.

The crowd stared at each other with wide eyes.

Doing experiments is like this, often doing it, there are some steps that need to wait, at this time, often prepare the things to be used in the next stage, or look at the paper, desert and so on.

It's just that a group of people are waiting here, which looks a little funny.

Director Fu looked around, and saw that everyone would rather stretch their necks and wait, and had no intention of going back to do research, so he sighed helplessly, and that was the only way, and he should give them half a day off.

I just hope that Chu Hao will come here like this once, if he comes every day, he won't be able to do experiments.

It wasn't easy, and thirty minutes of great suffering passed.

Chu Hao looked at the beaker, and then nodded in satisfaction.

Then add ninety-two milliliters of ionized water and stir for fifteen minutes. Chu Hao said.

After Yin Yulian finished adding ionized water, Meng Mao hurriedly ran over, took the stirring rod, and offered his courtesy.

Slowly, the graphite flake layer is stripped into graphene oxide by high-shear vigorous agitation, and a stable, light brownish-yellow single-layer graphene oxide suspension is formed in water.

And Chu Hao was also heating his own reducing agent on the side.

It's just that more and more bubbles came out, and Meng Mao saw that Chu Hao didn't react, so he boldly continued to stir.

Seeing the bubbles, the hearts of Director Fu and other researchers also hung up, the bubbles were caused by the side reaction of the decomposition of the oxidant, and of course, it was not ruled out that gases such as carbon dioxide were produced in the process of graphite oxide.

Once there are too many bubbles, it will be a test of the reducing agent, and if one is not done well, then the experiment can be declared a failure.

After the temperature of the reducing agent reached eighty degrees, Chu Hao directly took the stirring rod from Meng Mao's hand, and said while stirring: "It was the medium temperature reaction stage before, and now it is the final high temperature reaction and termination stage. ”

At this time, the green color in the solution with the consumption of high-valent permanganate slowly lightened, and the bubbles gradually disappeared.

The nervous expressions of the crowd slowly eased.
