Chapter 480: Experiment success rate

The name of the district is Zhongshan International, the legendary "Jinling Rich District".
When I was at school before, 6 Zhou faintly remembered who I heard, but who said it, I don't remember it.
The entire villa group is located in the northeast of the national 4a-level scenic area. The entire community occupies an area of ​​3,671 acres, and the plot ratio is only o.168. It includes a golf course and there is a comprehensive shopping mall not far away.
However, these six boats are not particularly concerned. He neither plays golf nor is keen on shopping.
As long as the house itself is good and the environment is suitable, it will be enough for him.
"This study is pretty good."
Standing in this antique study, 6 Zhou reached out and touched the bookshelf, and nodded in satisfaction.
Wang Peng, who walked to the side, touched the window, and looked at the two trees outside, and said.
"The location of the two trees outside is a bit off."
6 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 and ruin the overall beauty.
Wang Peng pointed in a direction: "That location is easy to form a blind spot of vision with the courtyard wall. If I turn in from there and walk along the root of the wall, I don't even need to bend down, believe it or not?"
His eyebrows jumped, and Wang Yalan smiled politely: "Sir, there is a professional security team in the community. The thief can't enter at all. Your worry is unnecessary."
Wang Peng raised his eyebrows with interest: "More professional than me?"
Wang Yalan froze for a moment, but she didn't know what to say.
What is "more professional than me"?
Could it be you or a professional thief?
6 Zhou coughed slightly, ending the topic: "You don't care about those two trees, at most I install a camera there."
To be honest, he is not a secret officer, nor is he engaged in weapons research. Even important information is not kept at home. Even if he is careful, he does not need to be so suspicious.
There may not be scholars who have a wider field of research than him in the world, but there are still more scholars than him. Even Princeton has a few, and some conspiracy theories can only be heard. If you believe it, there is a problem in your mind.
As for the future?
Later things will be said later, at least now worrying about this is purely superfluous.
After the house is transferred, he intends to install a surveillance system in the home, get a few drones, and hand over security to Xiao Ai.
Even if the two trees were there, he did not believe that humans could come in.
Wang Peng made a helpless expression.
"I just suggest ... Of course, the decision is yours."
Leaving the window, 6 Zhou glanced at the study again, "I like this house quite well, just this one."
...
At the time of Zhouzhou's house inspection, Hou Jinli, who had recently joined the Jinling Institute of Advanced Research, was also watching the house ... or dormitory.
After leaving the campus of HKUST, I did not expect to live in the campus of Jinda University again. Looking at the brand-new faculty dormitory and holding the suitcase of Hou Jinli, I was quite moved.
However, it doesn't seem that bad?
More than just not bad ...
Thinking of the institute's commitment to staff divisions, he couldn't help but be a little excited. The average price of houses around here is more than 30,000 yuan. As long as you have worked for one year, you can move in, and you can transfer it after eight years of work. Such rich conditions are still quite rare in domestic research institutions.
Especially for materials.
Of course, what excites him even more is that he will be part of the Nobels' laboratory from tomorrow.
Not to mention having money to take it, even if there is no money, I am afraid that a lot of people will go.
As soon as a few top issues are made, the whole person's worth is different.
After spending half a day packing up the new house, Hou Jinli spent his first night in Jinling in the staff and dormitory of Jinda University.
From this, it can be regarded as settled.
The next day, Hou Jinli took a taxi to the door of the Institute of Advanced Research, and went all the way to the Institute of Computing Materials located deep in the Institute.
From the main entrance of the institute to the building of the institute, there were two access controls along the way, and both were face recognition.
The Academy did not give them a buffer period for these newly recruited familiar environments. Basically, everyone has been assigned specific work since they reported yesterday.
But in fact, he didn't need the buffer period of familiar environment, he was doing similar work before coming here, and the research direction happened to be carbon nanomaterials.
To him, it was like changing places to experiment.
The only thing you need to be familiar with is the placement of reagents and instruments.
After confirming today's experimental task, Hou Jinli changed into an antistatic white coat, weighed 1og1oo mesh graphite powder, and mixed it with sodium nitrate solids in a ratio of 2: 1.
At this time, Yu Junda, who was in the same internship period as him, walked in from outside the laboratory.
"Today is making sg-1 samples?"
Hou Jinli nodded: "Well, the stock of the sample library is not enough. Is the method familiar?"
"Several times."
"That line, come over and help me."
In general, in addition to preparing the medicines or reagents required for experiments, they can also be purchased from other research institutes or enterprises.
However, the sg-1 material is a new technology that was only announced at the previous mRs autumn conference. Although related papers and experimental reports can be seen in many databases, there are not many laboratories capable of making it.
Starting with the preparation of graphene oxide, each step is critical.
According to the method adopted by Qian Zhongming, the step of adding potassium permanganate is divided into three reaction stages: low temperature, medium temperature, and high temperature.
When potassium permanganate is added in portions, the reaction temperature is about 2o degrees Celsius, and the stirring is about half an hour.
Then raise the temperature to 35 degrees Celsius and continue stirring for half an hour.
Then the reaction was poured into a certain amount of deionized water to make the solution turn bright yellow, and it was heated and stirred in a water bath at 98 degrees for half an hour. Finally, it is filtered and pickled, washed with water to neutrality, and then dried.
If all goes well, you should get a light reddish brown sample.
If everything doesn't go well, it's possible to get anything.
Many times, it is these details that test a researcher's experimental ability.
If you don't pay attention to these details, even with the same experiment report, it is possible to make two very different things.
In other words, if you can grasp these details, even if you can't become an outstanding researcher ~ EbookFREE.me ~, you can definitely become an excellent scientific research dog.
For Hou Jinli, these operations are not difficult.
He has been a scientific research dog for one year at the University of Science and Technology. He has done similar experiments countless times. The whole set of operation flow is flowing in one go, and Yu Junda's eyes are straight.
Although it is also a scientific research dog in 985 universities, unfortunately, he happens to be the one responsible for writing thesis ...
The preparation of graphene oxide was completed, and Hou Jinli did not take it lightly.
Next, he also needs to modify the graphene oxide by n-type doping and other methods according to the method described in the experimental report.
It can be said that these next steps are the key to success.
Unfortunately, although the experimental report has been clearly written, and he has carefully restored the operation on the experimental report, the development of things is not as smooth as he imagined.
What finally appeared to the two of them was a ball of black powder.
Realizing that the experiment had failed, Yu Junda's expression was a little awkward.
"... Can this thing be rescued?"
Hou Jinli was also embarrassed with a look: "Probably not."
The experiment itself has the saying of success rate, and one mistake is actually nothing.
It's just that this morning's efforts have completely gone ...
Sighing, Hou Jinli packed the sample into a small plastic bag.
On the way to the waste bucket, he squeezed the black and slippery samples.
Originally, he thought that the thing would become gray as soon as he rubbed it, but the irregularly shaped particles did not break.
When this unusual place appeared, Hou Jinli stopped and looked at the small plastic bag in his hand, and frowned slightly.
This thing seems like ...
Quite strong?
