I Have a Research Support System

After the conclusion and defense, Mr. Wei stayed in the venue and continued to listen to the fifth report. After that, there were still things like grading and signing waiting for him.

Xu Qiu returned directly to Caiyi 216.

As soon as she entered the door, Han Jiaying greeted her and asked:

"Brother, how are you talking?"

"It's okay."

"Then shall we go to Zhangjiang to do synthesis in the afternoon?"

"Okay, have lunch at noon, and then take the school bus."

A new round of synthesis experiments officially started.

However, judging from the time, today was a bit embarrassing, because Xu Qiu would have class tomorrow morning.

Experiments and classes, how to choose?

After thinking about it, I still choose to experiment, then I can only continue to skip classes.

The main reason is that the professional degree course "Nanomaterials" has almost no help for Xu Qiu.

If you switch to courses such as "Polymer Condensed Matter Physics" and "Semiconductor Physics", it is worth listening to.

...

Nowadays, many colleges and universities are doing curriculum reform, leaving students with more and more independent choices.

Like Shanghai University, it is considered to be a relatively early batch of teaching reform experimental universities.

Including undergraduate admissions, freshmen do not enroll students according to traditional majors, but in the form of experimental large classes, with 500 students in a large class, and second-year students are diverted, which is also part of the teaching reform.

In addition, the training plan for each student is relatively flexible, and there is no fixed curriculum.

Except for some compulsory professional courses such as "Mathematical Analysis" and "Organic Chemistry", most other courses can be chosen independently, such as six modules, general education courses, and professional elective courses.

Required courses account for less than half of the total credits.

In this regard, Xu Qiu's feeling is too vague, mainly because there is no comparison, and he doesn't know what it was like before the reform.

On the whole, it is a bit like formal engineering.

But compared to not changing it all the time, moving it, no matter what the result is, is a good thing for the development of education after all.

It's just frequent changes, which may be more difficult for those front-line personnel in charge of educational affairs.

...

After lunch, the two took the school bus to the Zhangjiang campus.

The next work is more repetitive.

After all, almost all the innovative parts were completed by Xu Qiu.

For innovative work, one more person may not improve work efficiency much.

For highly repetitive tasks, one more person is a real labor force, and the work efficiency can be approximately doubled.

Of course, the prerequisite is to train Han Jiaying to become a skilled worker.

Because when he was doing synthesis experiments before, he always let her watch from the side, but he never let her do it.

So now she is doing synthetic experiments, with almost zero experience in this area.

As for her operation of preparing devices in the glove box in the Handan campus, they are just appetizers, and the difficulty is not very difficult.

Like Xu Qiu back then, it took less than two weeks to learn all of them, which can be said to be enough.

However, the synthesis experiment is different and more difficult, and it still tests a person's operational skills and experimental talent.

Han Jiaying's project is to synthesize PBT2T, 3T, 5T series polymer donors.

Xu Qiu originally planned to ask her to help him synthesize the materials first.

But after thinking about it, this time I plan to inject about 500 mg of monomer at one time, which is three times the amount of the previous experimental injection.

If the junior girl misses and messes up, the loss will be too great.

The senior sister asked him to synthesize the same material, 500 mg.

After consideration, he finally decided to let the school girl do her own three series.

...

The two entered the A502 laboratory.

He has already explained the experimental procedure to Han Jiaying, and the next step is to directly operate it.

It's time to test the quality of the school girl.

Wear protective gear, set up equipment, redistill toluene.

While waiting, Xu Qiu began to introduce the precautions.

There are still many points to pay attention to. These are the valuable experiences summed up in the previous experiments.

For example, to apply vacuum silicone grease to improve sealing, how to control the amount of solvent added, and so on.

There are also some laboratory safety details, such as wearing multi-layer gloves, using lab coats with elastic cuffs, and so on.

Xu Qiu is going to go through the entire process of submitting responses first, as a demonstration for the juniors.

Unexpectedly, Han Jiaying took the initiative to say:

"Brother, can I carry out experiments simultaneously with you?"

"Yes, so confident." Xu Qiu said.

There should be no problem.

Although he agreed with his mouth, he was still worried in his heart.

So, while doing the experiment, he observed the school girl.

Of course, the main thing to look at is whether there is any problem with her experimental operation.

For Xu Qiu, this experiment is already very proficient.

As long as it's not a critical step, even if it's dual-purpose, it won't affect the overall experiment process.

And the school girl was very focused when she started the experiment.

Xu Qiu looked at it for a while, then moved his gaze upwards, and found that her face was still slightly flushed.

Although it is now autumn, doing experiments still consumes more energy, maybe because of the heat.

After observing for a while, he found a few small problems in the school girl's experiment, and pointed out directly:

"Large-sized rubber gloves are too big for you, and it is inconvenient to wear them for experiments. You can wear two layers of small-sized gloves, or you can get a few packs of medium-sized gloves.

In addition, after weighing the individual medicines, the corks should be plugged in time to prevent dust from falling in, or accidentally knocking over the bottle and spilling the medicines. "

"Okay, I understand." After Han Jiaying finished speaking, her face seemed to turn redder.

However, Xu Qiu didn't notice that much.

While experimenting, he compared the schoolgirl with the schoolgirl in his mind.

In comparison, considering the speed of the experiment, Han Jiaying's experiment ability is stronger.

As for other aspects, such as whether the experimental operation is stable and how good the physical fitness is, it remains to be observed.

...

Xu Qiu's first response was over, and he roughly estimated that it was more than ten minutes faster than Han Jiaying's progress.

He was not in a hurry to vote for the second batch, but patiently waited for her experiment to end.

Twelve minutes later.

After Han Jiaying completed the reaction, the oil bath was heated to 130 degrees Celsius and covered with aluminum foil.

Then, he asked expectantly:

"Brother, how is my performance?"

"It's great." Xu Qiu encouraged:

"In terms of experimental talent alone, it's about the same as me."

"Really, that's great, Senior Brother is my future goal." Han Jiaying said:

"One day, I will surpass you." After finishing speaking, she waved her fist.

"Haha, then I am really looking forward to that day." Xu Qiu said with a smile.

Next, the two continued to vote.

Xu Qiu's response to the vote just now is that the target product is PBT4T, and then he plans to help the senior sister vote for her three systems.

And Han Jiaying continued to vote for her other two systems.

As for the other four in Xu Qiu's own system, the equipment is really limited, so we can only do it next time.

However, even if the equipment allows, eleven responses can be cast at a time, and the subsequent post-processing will be troublesome, and it cannot be handled at all.

After all, this is reality, not a simulation lab.

In the evening, end the experiment.

Xu Qiu sent Han Jiaying to the school bus and told her to come to Zhangjiang early tomorrow, while he stayed overnight in Zhangjiang as usual.

After the inspection, the junior girl's condition is not bad.
