I Have a Research Support System

At five o'clock in the afternoon, material one 216.

As dinner time approached, the research team members who stayed in Handan were not in the mood to work, so they sat around their desks together.

Wu Feifei and Tian Qing were chatting, Duan Yun was browsing some forum, and Sun Wo was browsing Station B quietly.

Not long after, an organic trio appeared at the door of 216.

Xu Qiu, Han Jiaying and the others greeted each other, saying, "You decide what to do at night, just call us when you leave." Then they went to the inner laboratory together.

Tomorrow morning, I made an appointment for TEM test, and I need to prepare samples in advance. The time before dinner is definitely not enough for complete sample preparation, but I can do the preparation work first, and the two quickly divided the work. Xu Qiu went into the glove box to prepare the solution, and Han Jiaying went to clean it. glass substrate.

Chen Wanqing joined Wu Feifei and Tian Qing's discussion team. She put down her schoolbag and asked, "Teacher Wei is already on the plane."

"Well, Mr. Wei's flight was at 12 o'clock at noon. Before boarding the plane, he called me to ask about the situation of the research group." After a pause, Wu Feifei added: "His first stop is Stockholm, Sweden. It takes about ten hours to fly from Modu, and when he gets there, it will be after ten o'clock in the evening on our side, so don't worry."

"Okay," Chen Wanqing nodded, and then asked, "What are our plans for the evening?" Knowing that Teacher Wei left early last night, she got off the school bus and went straight back to her dormitory, but got vague information from Xu Qiu .

"Let's have dinner first, and then go to sing." Wu Feifei replied casually, she was scrolling through the public comments, suddenly stopped, and said: "How about we have a buffet at night, there is a new 'Tauren Buffet Hot Pot BBQ' on University Road , the main beef buffet, it looks pretty good.”

"How much is everyone?" Duan Yun interjected.

"The original price is 88, now the opening discount is 68 per person." Wu Feifei said.

"I have no objection," Duan Yun nodded in agreement, "The buffet at this price should be pretty good."

"Okay." "Yes." "I can do it, too. The name is worth a visit." Others responded one after another, and Sun Wo went in to ask Xu Qiu and Han Jiaying, and they had no opinion.

At about 5:30 in the evening, after discussing with several girls in the office, they decided on a place to sing. Xu Qiu and Han Jiaying also made preparations and came out of the laboratory.

Although Teacher Wei is not at school, everyone still maintains their usual work habits, and subconsciously uses the usual off-duty time, which is 5:30, as the limit.

"Let's go!" Duan Yun shouted, and everyone left the laboratory and marched towards Daxue Road.

Ten minutes later, they followed the navigation to the entrance of "Tauren Buffet Hot Pot BBQ" and entered the store.

Due to the newly opened event, there are still quite a few people, but the store here is also very large, with dozens of tables, and because today is Thursday, there is no need to wait for a table.

Wu Feifei followed the welcome guests to the front desk, where they need to pay in advance.

Of course, this time it wasn't Teacher Wei's treat, it must be AA's in the end, she paid in advance, and then others would transfer the money to her.

The single table here is a standard table for four people with a combination of shabu-shabu and grill, and there are seven of them in total.

So, Wu Feifei asked the waiter to find two empty tables and combine them into one.

After that, Sun Wo was left to look at the bag, and the others headed for the food pick-up place.

Vegetables and the like are placed in the vertical freezer, while meat and seafood are packed in boxes, stacked layer by layer, and placed in the box-type freezer. There are two rows of counters next to the freezer, where cold dishes, Oden, etc. are placed. Beverages, drinks, etc.

After shopping around, Xu Qiu found that the dishes were relatively homely, but they looked very fresh.

He speculated secretly in his heart, maybe it was because of the opening of the business just now, and it will be unknown what will happen after a while.

Xu Qiu acted together with Han Jiaying, she was in charge of selection, and he was in charge of handling.

Not long after, his hands were stacked with various boxes containing ingredients, including pork belly, black pepper steak, sliced ​​beef and mutton, large squid, marinated chicken offal...

Seeing that he couldn't hold it anymore, Xu Qiu had no choice but to go back and unload the cargo once.

After going back and forth, the two made a cold dish platter, including cloud silk, dried eggs, hot and sour kelp, salted peanuts, and some symbolic green leafy vegetables as decorations. After all, it was a buffet, and they mainly came to eat meat. Well.

Finally, when they came to the drink area, there was a bottle of Coke, Sprite, Fanta and soy milk in glass bottles. Here, they met Duan Yun.

Duan Yun held a few bottles of beer in his hand, and said familiarly: "Xu Qiu, drinks are free here, how many bottles do you want?"

"No, let's have a drink." Xu Qiu raised the drink in his hand and refused with a smile. Although he has a good capacity for alcohol, it was all forced to exercise at home. Compared with drinking, he still prefers to drink happy water.

After everyone selected the dishes, they returned to the table again. Although the table was put together, there were two stoves, so they were divided into two groups.

Xu Qiu, Han Jiaying, and Chen Wanqing had a table of three, and Wu Feifei, Tian Qing, Duan Yun, and Sun Wo had a table of four.

"Tauren self-service hot pot barbecue" here uses an electric barbecue stove, not a charcoal barbecue, which needs to be used with barbecue oil paper;

The hot pot on the other side is an induction cooker. It uses an ordinary bone broth pot bottom. Just put the ingredients in and cook, no need to operate.

Xu Qiu stared at the oven and asked, "Who will bake it?"

In an instant, two hands were pointed at him.

Although Xu Qiu had expected this result a long time ago, he still couldn't help complaining in his heart, you guys are too decisive.

He looked at the other side. It was Duan Yun and Sun Wo who were in charge of baking, which made the balance a little bit.

Han Jiaying is more experienced and began to direct:

"First roast the pork belly and refine the oil..."

"Pork belly must be roasted dry to be delicious..."

"After the pork belly is cooked, you can grill the rest. Let's serve three pieces of black pepper steak first, and you can brush with a little oil..."

"Use onion rings to surround the eggs, so that the egg liquid will not run around when you bake the eggs..."

"Waiter, change the paper~"

An hour later, everyone was full and ready to evacuate.

After Xu Qiu ate it, he felt that except for the black pepper steak and chicken giblets, the other dishes were quite satisfactory, not amazing, but not unpalatable, but after all, it was a cheap buffet, so he couldn't force too much.

Before leaving, everyone was stuffed with more than a dozen 10 yuan coupons. If you come back next time, you only need 78 people.

Han Jiaying touched her belly and sighed, "I'm going to gain weight again."

Tian Qing turned on her mobile phone to navigate, and said, "The next stop, Happy Di KTV, is not far from here, only more than 800 meters away."

"Let's go." Duan Yun waved his hand. He drank three bottles of beer, blowing the cold wind outside, and was a little bit above his head. Except for him, everyone else drank beverages. Duan Yun had no one to accompany him, so he drank too much. not much.

Happy Di KTV.

After the staff adjusted the equipment, everyone sang several hot songs with the microphone in turn.

When the song was about to end, Duan Yun suddenly booed: "Xu Qiu, Han Jiaying, don't you two sing a song together?"

Xu Qiu:?

He was half lying on the sofa, humming the lyrics softly, and was caught off guard. He sat up and looked around, seeing that no one else looked surprised, and suddenly realized that they all knew.

Xu Qiu and Han Jiaying exchanged glances. The school girl looked a little shy and blushed, but she didn't mean to resist too much.

Seeing that they didn't speak, Tian Qing took it as an acquiescence, and quickly clicked "You Will Marry Me Today", put it on the top, and then cut off the current song.

The prelude to the song sounded, a microphone was stuffed into Xu Qiu's hand from nowhere, and Han Jiaying was holding the other.

The two looked at each other and smiled. Although it was a bit unexpected, it was not bad to take this opportunity to disclose their relationship.

Han Jiaying sat next to Xu Qiu generously. The two held hands and began to sing together.

"The flowers bloom in the warmth of spring, taking away the sadness of winter..."

Watching the MV on the screen, the two gradually assumed the identities of the bride and groom in the picture, sometimes looking at each other, and sometimes shaking their bodies to the rhythm of the music.

Finally, after Xu Qiu sang three lines of "Today you will marry me", the song ended.

Han Jiaying suddenly leaned close to Xu Qiu's ear, whispered: "Okay~", and blew mischievously.

A strange feeling spread from Xu Qiu's ears to his whole body. It was numb, like an electric current flowing. Although it was only for a moment, the aftertaste was endless. ‘Heh, little goblin, I’ll clean you up tonight, I won’t let you get out of the lab today. '

After this episode, the rhythm in the KTV was controlled by Han Jiaying and Tian Qing, while the others drank tea, listened to songs and sipped soy sauce.

After ten o'clock in the evening, everyone finished the entertainment and returned to Material One.

Xu Qiu and Han Jiaying stayed and continued to prepare samples, while the others went back to their homes and found their own roommates.

The TEM samples should be free of water, so it is best to prepare them this evening, so that they can be left to dry naturally overnight.

It is not impossible to make preparations the next morning, but the Handan laboratory does not have an oven, so it must be dried with a hot hair dryer. If a hand shakes and the sample flies, it will be cooled directly.

Because there were not many experiments today, and because they slept on the way back, Xu Qiu and Han Jiaying were in a good state of mind.

They quickly entered the experimental state and began to spin-coat water-soluble PEDOT:PSS, spin-coat the effective layer, prepare disposable PE cups, and throw into the glass substrate that had been spin-coated with two layers of films.

Finally, use tweezers to pick up the copper mesh and touch it, using the remaining copper mesh from the last test.

A total of sixteen groups of samples, Xu Qiu and Han Jiaying's two optimal systems, four conditions for each system, namely pure chloroform solvent, chloroform + DIO solvent additive and pure chlorobenzene, chlorobenzene + DIO, two samples.

The two of them worked until midnight and finally finished the sample preparation.
