Chapter 149: 2-person world

After the experiment, Xu Qiu set off early and sent Han Jiaying to the school bus ride.
She had to catch the last bus at 9:30, but she still had to go in line in advance.
Although in most cases, the last bus was unsatisfactory, it would be difficult to return to the Handan campus if you happen to encounter a special situation and fail to catch the bus.
Taking a taxi is very expensive, and taking rail transit is very troublesome.
Because there is no subway station nearby, you need to take a tram first and then transfer to Metro Line 10.
The school is just between two subway stations, and it takes a long way to get off the subway.
While waiting for the bus, Xu Qiu saw that the school girl was still wearing very thin clothes and twitched her nose in the cold wind.
He approached Han Jiaying, protected her from the wind, and then cared:
"Wear more tomorrow."
Then, he changed the subject:
"Otherwise, if you catch a cold, who will do the experiment for me?"
"I know, brother," Han Jiaying smiled:
"Speaking of why you can say this kind of thing so confidently."
"As a senior, I should care about you."
"You know I didn't say this sentence."
"Well, the school bus is coming, I'm leaving, bye."
"Bye bye, pay attention to safety."
Xu Qiu stayed overnight as usual, went through the vending machine downstairs of Microelectronics, and bought a bottle of Tang Shuaibo green plum green tea.
Today, I need to add some moisture.
...
Early the next morning, Xu Qiu was woken up by the alarm clock.
He hurriedly put on his clothes, entered the A502 laboratory, put on protective equipment, and then went to the fume hood to check the reaction.
This time, there was no accident.
The six responses that the two cast looked normal.
So he opened the capping reaction, then returned to the office to wash, exercise early, eat early, and then go to the laboratory to start the second capping reaction.
Until around nine o'clock, the two capping reactions were almost over.
Xu Qiu got up to go to the laboratory to shut down the reaction, but met Han Jiaying at the door.
If he hadn't braked in time, the two would collide together.
Observe the school girl up close.
Today, she still wears autumn clothes, but she puts on a blue sweater jacket with cartoon patterns outside, which looks very warm.
"Brother, I want to go in..." Han Jiaying reminded in a low voice.
"Oh, good." Xu Qiu hurriedly got up and let go of his position. Only then did he realize that he was blocking the door.
"How about the synthesis reaction this time?" Han Jiaying put down her schoolbag and asked.
"It looks pretty good, now the capping reaction has just ended, let's post-processing together." Xu Qiu said.
"Okay." Han Jiaying said eagerly.
Today's post-processing process is relatively simple.
It is to drop the toluene solution in the reaction flask into methanol to precipitate, then filter, simply dry, and then use methanol, acetone, n-hexane three mixed solvents for Soxhlet extraction.
After the processing was completed, it was close to 12 noon, and the two went to the cafeteria together.
On the way, Xu Qiu began to plan the experiment:
Soxhlet extraction takes about 12-24 hours in theory.
Of course, if the synthesis reaction is relatively successful and the content of small molecules and oligomers in the polymer is relatively small, this time period will also be shortened.
But anyway, today's time is definitely not enough for the next experiment, which is to extract Soxhlet with chloroform.
Considering that tomorrow is Wednesday, there is a professional course of "Nanomaterials" in the morning, and I have skipped many times this semester.
Moreover, this batch of products is not as eager to publish a big article as the previous batches.
Therefore, Xu Qiu decided to stay at the Soxhlet extraction step with mixed solvents today.
Wait until the class is finished on Wednesday morning, and then return to Zhang Jiang to continue the experiment.
Mainly because the school stipulates that the number of students skipping classes exceeds one-third of the course hours, the teacher has the right to unconditionally refuse the student to participate in the final assessment and directly drop the course.
In a semester, a course takes about 16 to 20 weeks, that is, skipping more than 6 classes will trigger this rule.
Of course, most teachers don't call names, and they don't care about whether students come to class. They only complete their own teaching tasks, and their grades are usually full.
As long as the students come to take the final exam, they will give the students scores according to the final grades, and generally do not embarrass the students.
But after all, there are such regulations, and they still have to be respected. Xu Qiu didn't want to leave a handle outside.
In fact, a better way is to ask the teacher for leave. Normal teachers will agree to the special case of doing experiments.
However, it's okay to ask for leave occasionally. If you ask for leave five or six times a semester, even if the teacher didn't care, your name will be remembered.
As for the consequences, it is hard to say.
...
In the afternoon, it is relatively leisurely, and the Soxhlet extraction device is always on, so there is no need to go to see it.
You can even return directly to the Handan campus, let it extract for 24 hours, and wait until the next day to continue the experiment directly.
Xu Qiu thought for a moment, but decided to stay in Zhang Jiang.
Because to him, it's the same everywhere.
It might be better on Zhang Jiang's side, except for Han Jiaying, no one would bother him.
If there are many people and equipment in the Handan campus, Mr. Wei will come and go from time to time, and he may be distracted by various things and reduce work efficiency.
"Han Jiaying, today's experiment is over. What do you say, stay here or go back to Handan campus." Xu Qiu asked.
"Where is the brother, do you want to stay?" Han Jiaying said.
"Well, I'm writing papers here, Zhang Jiang is relatively quiet." Xu Qiu said.
"Then I will stay too. Yesterday, my senior brother taught me the method of documentation, and I just put it into practice today." Han Jiaying said:
"I feel that reading literature is more helpful to me than reading books like "Semiconductor Physics"."
"Each has its own merits. Most of the documents we see report on a material, and then characterize it with photoelectric properties." Xu Qiu said:
"At first, looking at these documents is really helpful, allowing you to systematically master the process of scientific research in the field of organic photovoltaics~EbookFREE.me~ But as the volume increases, the marginal effects of such documents are obviously diminishing, like Now, it is difficult for me to get too much from the literature related to this kind of material.
On the contrary, some theoretical books or literature are more helpful to me and can give me a deeper understanding of the operation mechanism of battery devices.
The articles published today are all about how and how good our materials are, but why it is good and how to reproduce it, but few people can understand it.
Theoretical research is still far behind. "
Han Jiaying seemed to understand but did not understand, but still expressed her opinion:
"I think with the strength of the seniors, in a few years, maybe a new and complete theory can be put forward."
"Let's borrow your good words," Xu Qiu unplugged the USB flash drive from the computer and said:
"Well, I'll copy the electronic version of the literature to you. You can find the latest literature and start to read it. If you have any questions, please feel free to ask me."
