Chapter 481 The Success Rate of the Experiment

The name of the community is Zhongshan International, the legendary "Jinling Rich District".

When he was in school, Lu Zhou vaguely remembered hearing someone say it, but he doesn’t remember who said it.

The entire villa group is located in the northeast of the national 4a-level scenic area. The entire community covers an area of ​​3671 mu, with a plot ratio of only 0.168. It includes a golf course, and there is a comprehensive shopping mall not far away.

However, Lu Zhou didn't really care about them. He neither played golf nor was he keen on shopping.

As long as the house itself is good and the environment is suitable, it is enough for him.

"This study is not bad."

Standing in this quaint study, Lu Zhou touched the bookshelf and nodded with satisfaction.

Wang Peng, who walked to the side, touched the window, glanced at the two trees outside, and said.

"The location of those two trees outside is a bit awkward."

Lu Zhou glanced out the window: "Why do you say that? I think it's pretty good."

Without those two trees, the entire front yard would look bare, ruining the overall aesthetic.

Wang Peng pointed in a direction: "That location can easily form a blind spot with the courtyard wall. If I turn in from there and walk along the base of the wall, I don't even have to bend down. Believe it or not, you won't notice it?"

Eyebrows twitched, Wang Yalan smiled politely and said, "Sir, there is a professional security team in the community, thieves can't get in at all, your worries are unnecessary."

Wang Pengrao raised his eyebrows with interest: "More professional than me?"

Wang Yalan was stunned for a moment, not knowing how to answer this question.

What is "more professional than me"?

Could it be that you are still a professional habitual thief?

Lu Zhou coughed lightly and ended the topic: "Don't worry about those two trees, at most I'll install a camera there."

To be honest, he is not a secret agent, nor is he engaged in weapon research, and he will not keep important information at home. Even if he is right to be careful, there is no need to be so suspicious.

There may not be scholars with a wider research field than him in the world, but there are still some scholars who are more powerful than him, and even Princeton has a few.

As for the future?

I'll talk about it later, at least for now it's just unnecessary to worry about it.

After the house is transferred, he plans to install a monitoring system for his home, and he is getting a few drones, and will hand over the security to Xiao Ai.

Even if those two trees were there, he didn't believe that human beings could climb in.

Wang Peng made a helpless expression.

"I'm just suggesting...Of course, the decision is yours."

Leaving the window, Lu Zhou looked around the study again, "I quite like this house, so let's take this one."

...

While Lu Zhou was looking at the apartment, Hou Jinli, who joined the Jinling Institute for Advanced Study not long ago, was also looking at the apartment... or the dormitory.

After leaving the campus of HKUST, he unexpectedly moved into the campus of Jinda University again. Looking at the brand-new faculty dormitory, Hou Jinli, who was carrying a suitcase, felt quite emotional.

However, it doesn't seem like such a bad feeling?

Not only is it not bad...

Thinking of the Institute's commitment to the division of housing in the staff quarters, he couldn't help but feel a little excited. The average housing price in this neighborhood is more than 30,000 yuan. As long as you have worked for one year, you can move in, and you can transfer the ownership after eight years of work. Such generous conditions are quite rare in domestic research institutions.

Especially for materials.

Of course, what excites him even more is that starting tomorrow he will be a member of the laboratory of the Nobel laureate.

Not to mention taking it if you have money, even if you don't have money, I'm afraid a lot of people are willing to go.

Once a few top publications are published, the value of the whole person will be different.

After spending half a day packing up the new house, Hou Jinli spent his first night in Jinling in the faculty dormitory of Jinda University.

From this, it can be regarded as settled down.

The next day, on the first day of work, Hou Jinli took a taxi to the entrance of the Institute for Advanced Study, and went all the way to the Institute of Computational Materials located deep in the Institute.

From the main entrance of the research institute to the building of the research institute, I went through the access control twice along the way, and both times were face recognition.

The research institute did not give them a buffer period to familiarize themselves with the environment for these new recruits. After reporting for duty yesterday, basically everyone was assigned a specific job.

But in fact, he does not need this buffer period to get familiar with the environment. Before coming here, he was engaged in similar work, and his research direction happened to be carbon nanomaterials.

For him, it was like doing experiments in another place.

The only thing that needs to be familiarized with is the reagents and the placement of the instruments here.

After confirming today's experimental task, Hou Jinli put on an anti-static white coat, weighed 10g of 100-mesh graphite powder, and mixed it with solid sodium nitrate in a ratio of 2:1.

At this time, Yu Junda, who was in the internship period like him, also walked in from outside the laboratory.

"Today is making the SG-1 sample?"

Hou Jinli nodded: "Well, the inventory in the sample library is not enough, are you familiar with the Hummers method?"

"Did it a few times."

"Okay, come here and help me."

Generally speaking, in addition to self-preparation, the drugs or reagents needed for the experiment can also be purchased from other research institutes or enterprises.

However, the SG-1 material is a new technology announced at the previous MRS autumn meeting. Although relevant papers and experimental reports can be seen in many databases, there are not many laboratories capable of making it.

Starting from the preparation of graphene oxide, every step is critical.

Taking the Hummers method adopted by Qian Zhongming as an example, the step of adding potassium permanganate alone is divided into three reaction stages: low temperature, medium temperature, and high temperature.

When adding potassium permanganate in portions, the reaction temperature is about 20 degrees Celsius, and the mixture is stirred for about half an hour.

Then the temperature was raised to 35 degrees Celsius, and stirring was continued for half an hour.

Then the reactants were poured into a certain amount of deionized water to make the solution turn bright yellow, and then heated and stirred in a water bath at 98 degrees for half an hour. Finally, pickling by suction filtration, washing with water until neutral and then drying.

If all goes well, the resulting sample should be a light reddish brown.

If things don't go well, anything is possible.

In many cases, it is these details that test a researcher's experimental ability.

If you don't pay attention to these details, even with the same experimental report, it is possible to make two completely different things.

In other words, if you can grasp these details well, even if you can't become an excellent researcher, you can definitely become an excellent scientific research dog.

For Hou Jinli, these operations are not difficult.

He has been a research dog at HKUST for a year, and he has done similar experiments countless times. The whole operation process is smooth and smooth, and Yu Junda's eyes are straightened.

Although he is also the scientific research dog of the 985 university, unfortunately, he happens to be the one in charge of writing the thesis...

After completing the preparation of graphene oxide, Hou Jinli did not take it lightly.

Next, he will modify graphene oxide by N-type doping and other methods according to the method in the experiment report.

It can be said that the next steps are the key to success.

Unfortunately, although the experiment report had been clearly written, and he was earnestly restoring the operations on the experiment report, things did not go as smoothly as he had imagined.

What finally appeared in front of the two was a cloud of black powder.

Realizing that the experiment failed, Yu Junda looked a little embarrassed.

"... Can this thing be saved?"

Hou Jinli was also embarrassed: "Probably not."

The experiment itself has a success rate, and one mistake is actually nothing.

However, this morning's hard work was completely in vain...

Sighing, Hou Jinli packed the sample into a small plastic bag.

On the way to the waste bin, he casually squeezed the dark sample.

Originally, he thought that this thing would turn into ashes as soon as he rubbed it, but it turned out that the irregularly shaped particles were not broken.

After discovering this unusual place, Hou Jinli stopped, looked at the small plastic bag in his hand, and frowned slightly.

This thing looks like...

Pretty solid?
