Chapter 194: How old is the doctor brother?

"I have a scientific research support system ( to find the latest chapter!
After reading the review comments, Xu Qiu went to Caiyi 218 to discuss with Teacher Wei.
"how is it?"
"A suggestion to switch to AELM, I think I can just ignore it."
"Well, reviewing a manuscript is more subjective. Don't take it too seriously like this one who directly recommends rejection without specific opinions."
"In addition, there is an opinion for minor changes, which is better, and there is an opinion for major changes. Three experiments need to be supplemented. This is more troublesome."
"Oh, that big change opinion, I took a closer look later, this language style must be Bazan, he is an old predecessor in this field, is the first group of people in foreign countries to do organic photovoltaics, I know him , I have cooperated before, so it’s a little friendship."
It turned out to be him. Xu Qiu has heard of the name Bazan. He is one of the few people in the field of organic photovoltaics who has published articles in the top issue of "Science", and there are also many articles in the big magazine of "Nature".
Unexpectedly, such a big man would personally review the manuscript for him, and his comments were very specific, obviously he had read his article carefully.
Teacher Wei said that he had cooperated with him and had some friendships, so he wouldn't be giving money to himself, just like "I have some friendship with the school principal. I have met once at the opening ceremony, and I have to meet again at the graduation ceremony."
Xu Qiu thought about it for a while, and continued: "The main problem now is that he asks for additional testing of TRPL data. We don't have such equipment in our school."
"Then do you think it is going to be tested?" Teacher Wei asked back.
Xu Qiu deliberated and said, "I think it is necessary. Although TRPL is an emerging technology, it still fits well in the field of organic photovoltaics."
"Okay, then we will test it." Wei Xingsi didn't ask any more, making a decisive decision.
Afterwards, he tapped the table with the middle two fingers, while muttering to himself: "I remember that there is a TRPL from Teacher Hou Kaihua of Sioux City University. I will contact you for your help."
"Well, you should prepare the solution first. After I get in touch, I will tell you the standards for sample preparation. It's hard work." After saying that, Teacher Wei handed over a bottle of Yiyun water as an order to expel guests.
...
On the way back to 216, Xu Qiu unscrewed the cap of Yiyunshui and took a sip.
‘It’s not much different from the farmer’s three punches. ’
"Han Jiaying, ready to work, each of the four systems of P4T and the solution of the blend components are made up of 1 ml." Xu Qiu said.
The school girl was stunned for a moment, then reacted and asked, "Is it going to be a sample of TRPL? Did Mr. Wei do it?"
"Not yet, but it seems that the problem is not big," Xu Qiu explained:
"Ms. Wei has friends at Sioux City University. They mainly do perovskites. They have a TRPL instrument. After the appointment, I may go to Sioux City on a business trip."
"Suzhou University?" Han Jiaying said with a strange expression.
"Yes, what's the matter?" Xu Qiu also noticed the abnormality of the school girl.
"My home is from Sucheng..." Han Jiaying whispered.
‘It’s such a coincidence. Before, I only knew that her hometown was from Suzhou, but I didn’t know that it happened to be from Suzhou. Xu Qiu muttered in his heart for a while, and then suggested: "Would you like to go there together, you can still go home by the way."
"Um... okay." Han Jiaying did not refuse.
After ten minutes, Xu Qiu was summoned to 218 by Teacher Wei.
"I have made an appointment with the teacher over there, and I can go directly to the test tomorrow. The standard for their sample preparation is'a glass substrate of one centimeter by four centimeters. It does not need to be coated evenly, as long as the middle two centimeters are coated. Just go up', I will send you the request and the contact information of the other party later."
"Okay." Xu Qiu nodded and said, "By the way, tomorrow I plan to take Han Jiaying with him."
"Okay, come back to me for reimbursement for the ticket and meal expenses." Wei Xingsi agreed directly.
Afterwards, he took out a can of tea from the cupboard, handed it to Xu Qiu, and ordered: "Bring this to Teacher Hou Kaihua."
...
Returning to 216 again, Xu Qiu said to the school girl who was preparing the solution in the glove box:
"Ms. Wei has made an appointment. We will test it tomorrow. Let's buy tickets first."
"Um... OK, will you buy it for me?"
"Okay, please give me your ID number later."
Xu Qiu opened the 12306 ticketing software and set up the city to and from.
Although it is during the Spring Festival travel season, it is relatively easy to buy high-speed train tickets from Moto to Sioux City. Buy one day in advance, and 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 them to get from school to the station by subway.
Thinking that the school girl is from Sucheng and is very close to demons, Xu Qiu asked, "When do you usually go home?"
"Um...I will come back almost every two weeks," Han Jiaying added: "Usually I go back on Saturday morning and come back on Sunday morning."
Xu Qiu smashed his mouth. It's good to be close to home. They return every half a month. He can only go home once in half a year.
After buying the ticket, Xu Qiu began to prepare the substrate.
The other party's request is 1 cm by 4 cm, and some of them are 2.5 cm by 7.5 cm slides.
It needs to be cut into a 2.5 cm by 4 cm substrate, and then cut again after spin coating.
There are a total of nine sets of samples, including four sets of polymers with separate components, four sets of blended components, and one set of PCBM. Three replicate samples are prepared for each.
Taking into account the loss in the spin coating process, it is enough to cut more than 30 substrates.
There is no corresponding instrument in the laboratory, 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 I changed the subway, high-speed rail, and subway back and forth, and arrived at Sioux City University smoothly, half an hour earlier than the agreed time.
He found it useful to bring Han Jiaying.
At least you don't need to use navigation, the school girl is a living map.
The two walked to the gate of the school. Because it was during the holiday, Sioux City University and Magic City University were similar, and the investigation was stricter.
Register visitors at the gatekeeper and enter the campus.
Han Jiaying volunteered to lead the way, and Xu Qiu agreed without much thought.
As a result, under her leadership, the two turned left and right on the campus and successfully lost their way.
"What about the good'living map'?" Xu Qiu teased.
"Furthermore, give me another five minutes." Han Jiaying refused.
"Let your tears freeze into ice..." Xu Qiu couldn't help singing along.
"You!" Han Jiaying flushed.
Xu Qiu sighed and said seriously: "We arrived half an hour earlier, but now it has been a quarter of an hour, and we will be late in a while. How about finding someone to ask for directions?"
"I can, trust me." Han Jiaying waved her small fist.
"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 inconspicuous small building in a very remote corner, which was the destination of the trip.
I seemed to have passed by the neighborhood once before and somehow missed it.
Xu Qiu glanced at the phone's clock, and there were three minutes left before the agreed time.
There was an entrance guard in this building and there were no people around, so he called the other party.
He was contacted by text messages before. This time he heard the voice full of breath, like a teacher, and the other party said very politely, "He will come down soon."
Not long after, a middle-aged man with a big belly and a little Mediterranean drove down from the stairs and opened the door.
Xu Qiu tentatively asked, "Teacher Hou Kaihua?"
"Yes, right, are you the students from Teacher Wei?" Hou Kaihua greeted the door while holding the door.
"That's right." The two nodded, and then followed Teacher Hou through a laboratory and walked into his office.
Xu Qiu took out Teacher Wei's tea leaves from his backpack and handed it over. Teacher Hou shrugged it off, and finally accepted it.
After that, Xu Qiu made a few more polite sentences, and went straight to the subject: "Mr. Hou, when can the test be taken?"
"It's okay now, I'll arrange it." Hou Kaihua put the tea away and got up to lead the way.
Along the way, he also introduced Xu Qiu to their laboratory.
Their laboratories are very large. There are three laboratories as big as Teacher Wei Zhang Jiang's laboratory.
Finally ~EbookFREE.me~ Hou Kaihua took the two before one of his doctoral students and specifically ordered that "test samples from Teacher Wei should be given priority today", and then left.
Xu Qiulai did some homework in advance. TRPL, or 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 produces fluorescence, and the fluorescence intensity will gradually decay over time. The time scale of this decay is on 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 carried out.
"How many samples are there?" the doctoral student asked, his name is Sun Wenyan.
"27." Xu Qiu took out the sample wrapped in two layers of garbage bags from his school bag.
"There are so many. Our instruments are slow to measure. It takes ten minutes to measure a sample." Sun Wenyan was a little embarrassed.
"My opinion on the article has just come back, and the data is rather urgent..." After that, Xu Qiuchao and Han Jiaying winked.
The school girl understood, 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 getting on the high-speed rail. His bag couldn't fit, so he deposited it with Han Jiaying.
"Brother Sun Wenyan, I brought you some gifts."
"This...well, since it's the task that Teacher Hou confessed, I will definitely help you test it." Sun Wenyan's face improved a bit, and he asked casually:
"Brother is your article? What journal did you submit?"
"Yes, I made one, she made two, cast AEM."
"Awesome, Dr. Brother is a few years old, and you all look pretty young."
"My senior year."
"My junior."
