I Have a Research Support System

"I have a scientific research support system ( to find the latest chapter!

At 9:05, the last school bus arrived late.

After the students waiting to get off the bus, the students waiting at the bus stop get on the bus in an orderly manner.

Xu Qiu and Han Jiaying remained as usual and found a connected position to sit down.

After seeing all the students boarding the car, the driver master did not wait much, turned off the lights in the car, and started with a kick.

Probably hurried home to hug his wife.

There were occasional whispered exchanges among students in the car. Xu Qiu yawned and leaned back in the chair.

Before long, he suddenly felt his shoulders sink. This touch...

He looked to the side, the school girl tilted her head and leaned towards him.

Xu Qiu silently leaned his body inward, adjusted a comfortable posture, and narrowed his eyes.

...

The next day, Thursday.

Although it is a rest, it is not a real holiday, but the intensity of the experiment is not as strong as before, and there are still work tasks.

Han Jiaying stayed at the Handan campus. She was responsible for the relevant characterization tests of twelve product samples. It was not difficult and did not require self-testing. They were all delivered in the form of samples.

In fact, it is the test carried out in the simulation laboratory II, and it needs to be tested again in reality.

Of course, in reality, cost must be considered when testing. It is certainly impossible to test all the characterization tests for every product. There are still trade-offs.

Twelve kinds of products, of which four are the products of the first reaction, eight are the products of the second reaction, all the characterizations of the four products of the first step are performed, and the eight kinds of the second step depend on the school girl. The freedom to play.

As for how to choose between these eight products, Xu Qiu certainly knew well, but he didn't talk to the school girl, but let her judge and play freely.

This can be regarded as a training and test for her, how to find the most labor-saving and cost-saving method on the premise that the desired analysis result can be obtained.

In the future, she will be left alone. She can't just say "Brother, come quickly" when she encounters problems.

That definitely won't work.

He and his senior sister came to Zhang Jiang's laboratory.

Chen Wanqing's main task is naturally to complete the separation and purification of the products of her two reactions.

Xu Qiu assisted the senior sister to pass the column while finishing the experiment a few days ago.

For example, washing test tubes, washing various glass instruments, and preparing alkaline tanks.

Before, he and his school girl were busy with the column and saved hundreds of dirty test tubes, but there was no time to wash them. The same goes for other round-bottomed flasks and eggplant-shaped flasks. There is more than one alkali tank and he can’t fit it today. It is necessary to prepare another one.

Then, after a busy day, Xu Qiu still had no time to write a review.

But today, there is no need to catch the last school bus. He returned to Handan with his senior at 8 pm.

Chen Wanqing went to Caiyi, but instead of going with him, he went straight back to the bedroom, brought the bathing equipment and went to the bathroom.

Congratulations, after almost a week, I finally took a hot bath again.

After returning to the dormitory again, I received a message from Han Jiaying: "Brother, do you plan to exercise early tomorrow morning?"

Xu Qiu thought for a while and replied directly: "Okay, at six forty in the morning, I'll be waiting for you downstairs in your bedroom."

Soon, the school girl returned an emoticon package [OK].

He just mentioned it casually at the time, and he didn't expect that the school girl would agree, but since she took the initiative to mention it now, it would be nice if someone accompanies it to exercise.

After all, he has to complete the system tasks every week. If he exercises late, he may not be able to do it because of the experiment. Therefore, he arranges most of the exercise time in the morning.

...

On Friday, Xu Qiu waited downstairs in Han Jiaying's bedroom five minutes in advance.

There were not many students at this time, and Xu Qiu met three people along the way.

Mainly because the school has not yet started, this Sunday is the student registration report, and the school will officially start next Monday.

If it is after the official start of school, this time is the time for early exercises in physical education, and the number of students on campus will not be small.

Of course, the issue of forging has nothing to do with him anymore, it is a matter for freshmen and sophomores.

‘It turns out that my university life has not enough balance, only the last semester is left. ’

"Di——" Xu Qiu looked up when he heard the door of the bedroom opening.

"Brother, I'm here." Han Jiaying waved her hand, then trot to her side, looking at him with a smile.

Xu Qiu looked at the school girl up and down, because she was going to run, she did not wear a thick padded jacket, but was dressed in sportswear, full of youthful vitality.

The two looked at each other for a while, and Xu Qiu felt that he would take the initiative to say something at this time, and he said, "It's not cold."

Han Jiaying was stunned for a moment, then chuckled, "It's really cold, let's go quickly."

The playground is in the southern district, not far from the bedroom, and the two of them walked for more than a minute and arrived.

There was no one inside, and the two jogged side by side on the outer track.

After only running for a lap, Han Jiaying couldn't hold it anymore, and began to gasp lightly, her face flushed.

Xu Qiu slowed down and suggested: "Shall we take a break and go to the cafeteria for breakfast?"

Han Jiaying refused to comply, and said in a coquettish tone: "Just walk with me like this."

Looking at the girl under the morning sun, Xu Qiu was slightly lost, and only after a while did he react: "Oh, good."

The two walked one circle, two circles...

Mainly communicate some campus gossip.

Han Jiaying obviously knew a little bit more about this, but Xu Qiu didn't let it go.

Although he usually doesn't pay much attention to it, there is an existence like Tao Yan in the dormitory, and any hot news will be heard immediately.

Unconsciously, half an hour passed.

"I'm a little hungry." Han Jiaying stopped suddenly.

"Let's go." Xu Qiu smiled.

There are also three canteens in the South District, namely Chunhui Canteen, South District Canteen, and a Halal Canteen.

The origin and meaning of the name Chunhui Canteen is unknown. It is a bungalow with only four or five dining windows and more than a dozen dining tables. The only feature is that there are some small portions of stir-fried dishes of your choice. The price is not expensive. It costs about 20 yuan.

The halal canteen in the southern district is not very different from other halal canteens.

The South District Canteen, referred to as Nanshi for short, is also called Difficult to Eat, as the name suggests, it is indeed the most difficult to eat among the three canteens on the Handan campus, but because it is open in the undergraduate dormitory area, you can eat if you don’t eat.

Of course, unpalatable is only relative. When Xu Qiu first enrolled, he felt that the meals in the canteens of the Magic University Comprehensive University were of the level of human delicacy, more than one grade higher than the school canteens in his high school.

However, after eating too much, the difference was also found. Southern food is indeed the most unpalatable.

In the end, the two chose Nanshi.

The reason is that the other two do not do it earlier.

Xu Qiu turned around and asked, "School girl, what do you eat?"

Han Jiaying looked at the food in the window and said, "Egg pancakes, soy milk."

The chef Xu Qiuchao said: "Two egg cakes, two cups of soy milk, two fried spring rolls, and one tea egg."

Swipe the card and take the meal.

A total of 13 yuan was consumed.

Xu Qiu carried the dinner plate, and the two found a table to sit side by side.

"Will you go to Zhangjiang later?" Han Jiaying took a sip of soy milk and asked casually. The two hadn't talked about experiment-related content before.

"Let’s not go today," Xu Qiu picked up the egg pancake and took a bite. "This Friday is more embarrassing. Most of you will have to work overtime if you voted. If you don’t work overtime, the next time you go may be next Monday. This week Register today."

"Yes, I have to register on Sunday, I almost forgot about it." Han Jiaying was still drinking soy milk.

"By the way, what samples did you send yesterday?" Xu Qiu asked.

"I sent eight samples. Among them, four PDI molecules were obtained in the first reaction, and the products 1, 3, 5, and 7 were separated yesterday. I guess these four PDI molecules are substituted with monobromo , But the specific results will not come out until about a week." Han Jiaying added:

"What shall we do after the experiment? Wait for the characterization results to come out, or?"

"Our heroes see the same thing. I also think these four are monobrominated." Xu Qiu nodded. He had already got the result in advance. Naturally, she knew that the school girl's inference was correct. She seemed to be able to stand it. Tested, "In this case, we can vote for a reaction next week to test the water."

In fact, without using characterization methods ~www.ltnovel.com~, you can also roughly infer the corresponding attribution of the product based on the phenomena in the experiment process and the synthesis experience, but the accuracy rate cannot reach 100%.

For example, before Xu Qiu got all the characterization results, he was 70% sure to determine the attribution of the product. When he got one characterization result, it was increased to 90%. After getting three characterization results, the accuracy rate was infinitely close to 100. %.

Now the school girl has guessed it right by herself, and when she responds later, she doesn't have to spend any more to explain to her.

Xu Qiu ordered more meals, but the school girl's movements for eating were slower, and in the end the two of them resolved the battle at the same time.

After that, Han Jiaying went back to the bedroom and approved a coat, and the two went to Caiyi together.

Today, the organic trio rarely went to Zhangjiang, and the Handan Laboratory was back to full capacity.

When Teacher Wei came to the laboratory in the morning, he was taken aback when seeing all three of them, and then asked about their work progress.

In fact, the main question was Xu Qiu's progress in PDI here. Chen Wanqing returned from Zhang Jiang every day, and would squat until after get off work before returning to her bedroom.

Xu Qiu sorted out his thoughts and reported truthfully:

"Four kinds of PDI molecules were synthesized and 4-5 grams of high-purity products were obtained. Each product was reacted with 500 mg of raw materials and liquid bromine, and eight kinds of mono- and di-bromo substituted products were obtained. The separation and purification have been completed. Yesterday, samples of these materials were sent to test nuclear magnetic, mass spectrometry, infrared, etc. for characterization."

"The progress is so fast?!" Teacher Wei was shocked. He had experienced synthesis, which was almost a normal two-week workload.

He smiled and patted Xu Qiu on the shoulder: "Thanks for your hard work, write a summary today and relax. You can go out to eat in the evening and ask me for reimbursement when you come back."
