I Have a Research Support System

After reading the review comments, Xu Qiu went to Caiyi 218 to discuss with Mr. Wei.

"how?"

"A suggestion to switch to AELM, I think it can be ignored directly."

"Well, reviewing manuscripts is relatively subjective. Don't take it too seriously if you directly suggest rejecting manuscripts without specific comments."

"In addition, there is a suggestion for a minor correction, which is easier to correct, and there is a suggestion for a major correction, which requires three experiments to be supplemented, which is more troublesome."

"Oh, the opinion of the big change, I looked carefully at the back, the language style must be Bazan, he is an old man in this field, and he is the first batch of people in foreign countries to do organic photovoltaics. I know him well. , We have cooperated before, so it can be regarded as a little friendship."

It turned out to be him, the name Bazan Xu Qiu had heard of, and he was one of the few people in the field of organic photovoltaics who had published articles in the top journal of "Science", and there were also many articles in the main journal of "Nature".

I didn't expect that such a boss would personally review the manuscript for him, and the comments were very specific, obviously he had read his article carefully.

Mr. Wei said that he had cooperated with him and had some friendship, so it would not be giving himself money, just like "I have some friendship with the principal of the school. I met once at the opening ceremony, and I will meet again at the graduation ceremony."

Xu Qiu thought wildly for a while, then continued: "The main problem now is that he asked for additional TRPL data testing, and we don't have such equipment in our school."

"Then do you think we need to test it?" Teacher Wei asked back.

Xu Qiu thought about it and said, "I think it is still necessary. Although TRPL is an emerging technology, it is more suitable for the field of organic photovoltaics."

"Okay, then we'll test it." Wei Xingsi didn't ask any more questions, and made a quick decision.

Afterwards, he tapped the table with his middle two fingers, and said to himself: "I remember that Mr. Hou Kaihua of Sioux City University has a TRPL. Let me contact you."

"Well, you go to prepare the solution first, and I will tell you the standard for preparing the sample after I get in touch. Thank you for your hard work." After speaking, Teacher Wei handed over a bottle of Yiyun water as an order to evict the guest.

...

On the way back to 216, Xu Qiu unscrewed the bottle cap of Yiyun Water and took a sip.

‘It doesn’t feel much different from Farmer’s Three Punches, and I don’t know how it was hyped up. '

"Han Jiaying, get ready to work. Prepare 1ml of the solutions of the individual and blended components of the four P4T systems." Xu Qiu greeted.

The school girl was stunned for a moment, then she came to her senses and asked, "Do you want to make a sample of TRPL? Did Teacher Wei get it done?"

"Not yet, but from the looks of it, it's probably not a big problem," Xu Qiu explained:

"Ms. Wei has a friend at Sioux City University who mainly makes perovskites. They have a TRPL instrument. After making an appointment, I may go to Sioux City for a business trip."

"Sioux City University?" Han Jiaying asked with a strange expression.

"Yeah, what's the matter?" Xu Qiu also noticed the abnormality of the school girl.

"My home belongs to Su Cheng..." Han Jiaying said in a low voice.

'What a coincidence, I only knew her hometown was from Suzhou Province, but I didn't know it happened to be from Suzhou City. ’ Xu Qiu murmured inwardly for a while, and then suggested: "Would you like to go there together, and you can still go home by the way."

"Well... yes." Han Jiaying did not refuse.

After ten minutes, Xu Qiu was summoned to 218 by Teacher Wei.

"I have already made an appointment with the teacher over there, and I can go directly to test it during the day tomorrow. Their sample preparation standard is 'a glass substrate with a scale of one centimeter by four centimeters. It does not need to be coated evenly, as long as the two centimeters in the middle are coated." It's fine, I'll send you the request and the contact information of the other party later."

"Okay." Xu Qiu nodded and said, "By the way, I plan to take Han Jiaying there with me tomorrow."

"Okay, I will reimburse you for the train ticket and meal expenses when you come back." Wei Xingsi agreed directly.

Afterwards, he took out a can of tea from the cabinet, handed it to Xu Qiu, and ordered: "Take this to Teacher Hou Kaihua."

...

Returning to 216 again, Xu Qiu said to the junior who was preparing the solution in the glove box:

"Teacher Wei has already made an appointment, and we will go to test tomorrow. Let's buy the ticket first."

"Well... okay, can you buy it for me?"

"Okay, give me your ID number later."

Xu Qiu opened the 12306 ticketing software and set up the round-trip city.

Although it is the Spring Festival travel season, it is relatively easy to buy high-speed rail tickets from Shanghai to Sioux City. If you buy it one day in advance, there are basically tickets for second-class seats.

And the speed of the high-speed rail is also very fast, it only takes about half an hour to get there, which is less than the time it takes for them to travel from school to the station by subway.

Thinking that Xuemei is from Sucheng and is very close to the devil, Xu Qiu asked, "When do you usually go home?"

"Well... I go back about once every two weeks," Han Jiaying added, "I usually go back on Saturday morning and Sunday morning."

Xu Qiu slammed his mouth, it's good that the family is close, and they come back once every half a month. He can only go home once in half a year.

After buying the tickets, Xu Qiu began to prepare the substrate.

The other party's request is 1 cm by 4 cm, and they have slides that are 2.5 cm by 7.5 cm.

It needs to be cut into a substrate of 2.5 cm by 4 cm first, and then cut again after spin coating.

A total of nine sets of samples were prepared, including four polymer sets of individual components, four sets of blended components, and one set of PCBM, each of which was prepared in triplicate.

Considering the loss in the spin-coating process, it is enough to cut more than 30 substrates.

There is no corresponding instrument in the laboratory, and it is troublesome to measure.

...

the next day.

Xu Qiu estimated the arrival time and sent a text message to the other party in advance.

Then the subway, high-speed rail, and subway changed back and forth, and arrived at Sioux City University smoothly, half an hour earlier than the agreed time.

He found that it was useful to take Han Jiaying with him.

At least there is no need to use navigation, the school girl is a living map.

The two walked to the gate of the school. Because it is the holiday period, Sioux City University is similar to Shanghai Comprehensive University, and the inspection is stricter.

Register as a visitor at the gate guard to enter the campus.

Han Jiaying volunteered to lead the way, and Xu Qiu agreed without thinking too much.

As a result, under her leadership, the two turned left and right on campus and successfully lost their way.

"Where's the 'living map' that you promised?" Xu Qiu teased.

"Also, give me another five minutes." Han Jiaying refused to accept.

"Let your tears freeze into ice..." Xu Qiu couldn't help but sang along.

"You!" Han Jiaying blushed.

Xu Qiu sighed, and said seriously: "We arrived half an hour earlier, but now a quarter of an hour has passed, and we will be late in a while, why don't we ask someone for directions?"

"I can do it, trust me." Han Jiaying waved her small fist and said.

"Okay." Xu Qiu shrugged, then give her another chance.

Fortunately, the school girl didn't disappoint him this time. The two turned left and right again, and finally found an unremarkable small building in a very remote corner, which was the destination of this trip.

It seems that I passed by here once before, but somehow I missed it.

Xu Qiu glanced at the clock on the phone, and there were three minutes left before the agreed time.

This building has access control, and there is no one around, so he called the other party.

He used to contact him by text message, but this time he heard the voice, full of air, like a teacher, and the other party said politely, "He will be down soon."

Not long after, a middle-aged man with a Mediterranean appearance and a pot belly drove down from upstairs and opened the door.

Xu Qiu tentatively asked, "Teacher Hou Kaihua?"

"That's right, are you the students from Teacher Wei's side?" Hou Kaihua greeted, holding the door open.

"That's right." The two nodded, and then followed Mr. Hou through a laboratory and into his office.

Xu Qiu took out Teacher Wei's tea leaves from his backpack and handed it over. Teacher Hou shied away a bit, but finally accepted it.

Afterwards, after a few polite words, Xu Qiu got straight to the point: "Mr. Hou, when can I take the test?"

"It's fine now, I'll arrange it." Hou Kaihua put the tea away, got up and led the way.

Along the way, he also introduced their laboratory to Xu Qiu and the others.

Their lab is very big, there are three labs as big as Mr. Wei Zhang Jiang's lab.

In the end, Hou Kaihua brought the two of them to one of his doctoral students, and specifically told him to "test the samples from Mr. Wei's side first today", and then left.

Xu Qiu did some homework in advance. TRPL, that is, transient fluorescence spectrum, is similar to the steady-state fluorescence PL spectrum in the laboratory.

Transient means that a transient laser pulse is given to the material. Under the action of the laser pulse, the sample generates fluorescence, and the fluorescence intensity will gradually decay with time. The time scale of this decay is at the nanometer level.

The final curve obtained is the curve of fluorescence intensity changing with time, and then this curve is fitted, and some mechanism analysis is performed on it.

"How many samples are there?" asked the doctoral student, his name was Sun Wenyan.

"27 pieces." Xu Qiu took the sample wrapped in two layers of garbage bags out of his schoolbag.

"There are so many. Our instruments here are relatively slow. It takes ten minutes to measure a sample." Sun Wenyan was a little embarrassed.

"I just came back with my opinion on the article, and the data is urgent..." After speaking, Xu Qiu winked at Han Jiaying.

The school girl understood, and took out two Zhou Gray Duck gift boxes from her backpack, and put them on the desk next to her.

Xu Qiu bought this before he got on the high-speed rail, and he couldn't fit his bag, so he kept it with Han Jiaying.

"Senior Brother Sun Wenyan, I brought you some gifts."

"This...well, since it's the task entrusted by Mr. Hou, I will definitely help you to test it." Sun Wenyan's complexion improved, and he asked casually:

"Brother, is your article, what journal did you submit for?"

"Yes, I will be the first one, and she will be the second one. I voted for AEM."

"Awesome, how old is the brother doctor, and you all look very young."

"I'm a senior."

"I'm a junior."
