I Have a Research Support System

A few days later at noon, when Xu Qiu was having lunch at home, his mother Bai Xiaofen suddenly said, "My son, the child of Aunt Shu Yan's friend's family wants to come to meet you this afternoon. She is from No. 2 Middle School in the provincial capital. I just finished the college entrance examination this year and entered Zhejiang University..."

The relationship between Aunt Shu Yan and her mother, Bai Xiaofen, is probably similar to that of best friends. The former rented a small shop in the shopping mall on the pedestrian street in her hometown, opened a clothing store, and started a small business.

When Xu Qiu was young, he still often saw Auntie Shuyan visiting from home. However, since he went to the provincial capital to study in high school, and then was admitted to Shanghai Comprehensive University, he hadn't seen Aunt Shu Yan for many years.

Xu Qiu was not against their visits. He took a mouthful of the braised noodles in the bowl and asked casually, "Oh, is it a man or a woman?"

"It's a girl, and their hometown is also on our side, so they can be regarded as fellow villagers." When Bai Xiaofen said the word "girl", her eyes seemed to be shining brightly.

"Okay, let's meet then." Xu Qiu nodded casually.

"Let me talk to Auntie Shu Yan..." During the conversation, Bai Xiaofen suddenly showed an inexplicable smile, and Xu Qiu felt hairy when he saw it: "When will you bring a girlfriend home? Not bad, how about you have a good communication with her..."

Xu Qiu shook his head hastily, and found an excuse: "...I'm already in my first year of graduate school, and Zhejiang University is only a freshman, and I'm four levels short, so it's not suitable."

He and Han Jiaying hadn't told his family yet. It wasn't that Xu Qiu planned to open a fishpond to raise fish. The main reason was that he was afraid of his mother Bai Xiaofen's nagging:

As a mother, when you are single, you will urge to find a partner; when you find a partner, you will urge to get married; when you are married, you will urge to have a child...

It's better to talk about it later.

"It's only four grades away," Bai Xiaofen refuted Xu Qiu's point of view, with a persevering look: "Counting in the two years you went to school earlier, maybe your actual age is only two or three years apart, so it's appropriate..."

It is impossible to win an argument with mother, so Xu Qiu chose to change the subject: "When will they come over in the afternoon?"

"I don't know about this, let me ask you, Auntie Shu Yan." Bai Xiaofen was indeed distracted, and began to send messages slowly using the handwriting input method.

Xu Qiu quickly finished the braised noodles in the bowl, dropped his chopsticks, and slipped into his bedroom.

After closing the door, Bai Xiaofen's voice was heard from a distance: "They came after three o'clock in the afternoon—"

Xu Qiu responded from the air: "Okay——"

At about three thirty in the afternoon, the doorbell rang.

Bai Xiaofen stood up and opened the door to greet her. There were three visitors outside the door.

Among them, one is Aunt Shu Yan. Although they haven't seen each other for several years, Xu Qiu can still recognize each other. The other two are strangers. It seems that they are mother and daughter. There is a high probability that they are the visitors who made an appointment today.

Xu Qiu took a rough look at the two strangers.

The younger girl is very well-groomed, with short hair and good looks. She feels like the little girl next door. I don’t know if it’s Xu Qiu’s illusion. He feels that the other party has been staring at him since he entered the door. .

Older mothers dress more formally and look well maintained. They may be dedicated housewives or engaged in non-manual jobs.

Like the relatively backward fifth-tier cities in my hometown, many families are still struggling, and many of them have not even escaped poverty.

For example, Xu Qiu entered the Hongzhi class in high school, and nearly half of the students in it came from poor families.

Another example is that washing machines are not fully popular in my hometown. If the conditions at home are not good enough to afford a washing machine, housewives have to use washing powder, soap, and a washboard to wash clothes manually. If things go on like this, the hands will definitely change. Cracked, not well maintained.

Judging from the appearance alone, the mother and daughter's family conditions are likely to have surpassed 90% of the local families in their hometown.

Xu Qiu took the initiative to step forward and said hello, "Hello, Aunt Shu Yan."

Shu Yan smiled and said with a dialect accent: "Xu Qiu, it's been a long time since you went to the provincial capital to study, and I often hugged you to play with you when I was young."

After finishing speaking, Shu Yan turned around and pointed to the strange mother and daughter and introduced: "This is Liu Qingqing, this is Liu Qingqing's mother, Hu Yao, I mainly brought Liu Qingqing here today, and asked Xu Qiu for advice."

Xu Qiu waved his hand modestly: "I can't talk about advice, but Liu Qingqing, if you have any doubts about college, I can tell you."

Bai Xiaofen waved to Xu Qiu and Liu Qingqing: "Then you guys go inside and chat, we'll chat outside in the living room."

Hu Yao also nodded: "Qingqing, you and brother Xu Qiu can go together."

Liu Qingqing walked to Xu Qiu's side as she said, and said, "Okay~"

Xu Qiu couldn't laugh or cry in his heart, he tried every means to create opportunities for himself, but he didn't need it.

However, he did not refuse, and took Liu Qingqing to the study.

If the juniors communicate, it is really inconvenient if there are adults around.

Unexpectedly, as soon as the two of them entered the study, Liu Qingqing stared straight at Xu Qiu and said, "Xu Qiu...senior, I seem to have seen you...have you been on Weibo before?" that?"

"I did go to a hot search on Weibo..." Xu Qiu nodded, recalling the situation at that time in his mind.

It was an undergraduate graduation, and his graduation thesis was selected as one of the top ten outstanding graduation thesis in the country, and was also interviewed by Shanghai TV Station. Finally, it was also featured on Weibo's trending list and trending list at the same time.

However, the popularity didn't last long at that time, and it was squeezed out by traffic stars.

It has been more than half a year now, and I didn't expect to be recognized by someone.

To be honest, in his hometown, basically no one pays attention to the scientific research circle, which is why Xu Qiu rarely mentions his circle in his hometown.

If you forcefully talk about the specific situation in the scientific research circle with relatives and friends outside the circle, although it is a bit inappropriate to describe it as "playing the piano to the cow", it does mean playing the piano to the cow.

No way, the scientific research circle is a relatively distant place for most people, and it is also a very unfamiliar concept.

Like most other professions, whether it is doctors, lawyers, civil servants or whatever, ordinary people can usually see, come into contact with, and imagine the specific conditions of these professions.

For most people, scientific research is like a black box. Not only are there relatively few news reports, but the threshold for understanding the specific situation is also very high.

Except for going to graduate school in person, it is basically difficult to understand the more real scientific research circle through other means.

Because now whether it is a popular novel or a popular TV series related to the scientific research circle, the traces of artistic processing are too much, and the reduction rate of 50% is not bad.

It can be said that today's scientific research circle is one of the industries that are most isolated from the world.

After receiving Xu Qiu's positive response, Liu Qingqing's eyes lit up, a bit like a fan meeting a celebrity, but she was more restrained and did not rush directly, but her tone was still very excited:

"Then you must be right. I remember that I had just finished the college entrance examination and was waiting for the results of the college entrance examination. When I checked Weibo, I saw a report about you. I was very impressed. You were wearing a white coat. I still saved that photo of you, I didn’t expect to see a real person today!”

When she was young, chasing stars was a common phenomenon. Liu Qingqing also chased stars, but she was different from other peers. She didn’t like those sissy kimchi country stars. She admired famous scientists and paid attention to scientific research. news.

It's a pity that there are too few news related to scientific research reported in the mainstream media now, and in many cases there is no valuable news for several days in a row.

Therefore, when Xu Qiu's deeds appeared on Weibo, Liu Qingqing immediately became a fan of Xu Qiu.

At that time, she also searched Xu Qiu's Weibo and wanted to pay attention to it, but unfortunately she didn't find it because Xu Qiu didn't use Weibo.

Later, Liu Qingqing's college entrance examination was over. She originally wanted to study in Shanghai Comprehensive University and follow in the footsteps of idols, but found that her scores were not enough...

Then, thinking of the next best thing, go to Jiaotong University, which is also located in Shanghai, but the score is still not enough...

But if she went to other universities in Shanghai, such as Tongji University, she would be a little unwilling.

So, Liu Qingqing finally went to Zhejiang University.

After all, Zhejiang University is also good at engineering. She thought that since the outcome of the college entrance examination was doomed and could not be changed, she would go to Shanghai University for postgraduate study when she was a graduate student.

Liu Qingqing stammered a little excitedly: "I, I, wait...can you sign for me."

"Haha, of course." Xu Qiu was a little flustered by Liu Qingqing's flattery, and asked casually, "Liu Qingqing, this year's college entrance examination, Zhejiang University, how many points did you get?"

Liu Qingqing responded: "The naked score is 641 points, plus 20 points for the provincial first chemistry competition."

"Okay," Xu Qiu said in admiration, "You have higher scores in the college entrance examination than I did back then, why don't you come to Shanghai Comprehensive University?"

"I originally wanted to go to Shanghai Comprehensive University, but the score was not enough," Liu Qingqing stuck out her tongue: "Maybe this year's college entrance examination questions are simple, and the score line is relatively high. My province's science ranking is 132nd, and Shanghai Jiaotong University I couldn’t make it up the score line, so I ended up going to Zhejiang University.”

Xu Qiu nodded. At the beginning of the college entrance examination, he ranked more than 70 students in science subjects in the province. Generally, the top 50 students in the province went to Qingbei University, Hong Kong University, and Hong Kong University of Science and Technology. After that, 50-150 students went to Shanghai Comprehensive University, Shanghai Transportation University, Zhejiang University.

Among them, Modu Comprehensive University may have the third highest score line because of the relatively small number of recruits, only about 10 people, second only to Qingbei University.

"What major did you choose?" Xu Qiu asked again.

"Chemistry." Liu Qingqing said crisply.

"Chemistry..." Xu Qiu repeated, and then gave a thumbs up: "You have courage, do you like scientific research more?"

"Yeah." Liu Qingqing nodded, and then asked: "Senior Xu Qiu, what do you think of the chemistry major, and if you want to do research in the future."

"You are quite similar to me. You also like chemistry. When I was an undergraduate, the choice of materials chemistry was also related to chemistry." Xu Qiu didn't answer Liu Qingqing's question directly, but changed the subject and asked: " If you want to do research...how is your family condition?"

Although Liu Qingqing was a little puzzled as to why Xu Qiu asked such a question, she still replied seriously: "...It's okay, my family is in the catering business."

Xu Qiu let out a "hmm" and continued to ask: "Then how are you doing in mathematics?"

"It's okay... I won the second prize in the provincial competition in mathematics competition. It is said that I will be able to enter the first provincial competition by 3 points. It's a pity." Liu Qingqing paused and said, "It's a little difficult for me to improve my mathematics in the first semester of my freshman year. , but brushed "Jimidovich", and scored 92 points at the end of this semester."

"Well... what about English?" Xu Qiu asked.

"The score is 145 in the college entrance examination. I just passed the fourth level of the exam this year, but the score has not yet come out. It is estimated that the score is at least 600..." Liu Qingqing responded.

"666, the expert is actually by my side..." Xu Qiu compared a 6 with his hands, shook it, and asked, "Where's the grade point?"

Liu Qingqing was greatly appreciated by Xu Qiu's praise, her face turned red, and it took a few seconds before she responded: "...Grade point, the grade point is 4.51, I failed a ZZ class this semester, delay If you don’t get the total grade point, you can get a 4.6.”

"4.51?" Xu Qiu quickly realized that Zhejiang University should have a 5-point GPA, and when converted to the 4-point GPA of Shanghai Comprehensive University, it should be 3.61, which is quite strong and appropriate. Female top student, she is only a little worse than when she first entered school.

After understanding Liu Qingqing's basic situation, Xu Qiu thought about it for a while and said:

"First of all, not everyone is suitable for scientific research. If you are not very obsessed with scientific research, I actually suggest that you consider switching to computer science or management... However, Zhejiang University is good at engineering, so it may not be a good choice to switch to economics and management. Choice, but switching to a computer to become a program is probably a good choice, at least in terms of the difficulty of employment and income in the future, the salary and ease of employment of a computer will definitely far exceed that of chemistry in a short period of time."

Liu Qingqing patiently listened to Xu Qiu's words, and said with a smile: "But I like scientific research~"

"Well, then just pretend that I didn't say anything just now." Xu Qiu spread his hands, and he could see that Liu Qingqing's belief was relatively firm, probably because of the influence of her family.

Xu Qiu blindly guessed that maybe Liu Qingqing's father or mother was obsessed with scientific research, but they missed it for some reason at the time and had no chance to enter the industry, so they wanted their daughter to experience the life they had dreamed of instead.

Next, Xu Qiu said intermittently: "If you choose to do scientific research, you can study professional courses in the first semester of your freshman year during the winter vacation in advance, and then take more credits in the next semester..."

"In this way, when you are a sophomore, you will have enough time to enter the research group and get a general understanding of what scientific research is..."

"Because scientific research is something that needs to be experienced by oneself. Even if I tell you the hype, you may not be able to understand it..."

"Well, when the time comes...you can tell me the direction you want to choose, and I can give you some suggestions..."

"Afterwards, if you are in your junior year and confirm that you want to take the path of scientific research, I suggest you choose the path of going abroad..."

"Whether it is from the perspective of gold plating or broadening horizons, if you are determined to do scientific research, going abroad at the graduate level is the most cost-effective choice..."

"Then you can find the school you want to go to in advance and prepare for the corresponding language test. If you want to save money, you can start to prepare for the school application yourself. If you want to save trouble, you can find an overseas study agency to handle it..."

"In addition, you have to be mentally prepared. It may be several times more difficult for girls to choose scientific research than boys..."

"Hmmmm..." Liu Qingqing nodded thoughtfully, and finally said, "Shall we add a WeChat account? Maybe I will ask Senior Xu Qiu again later."

"Yes." Xu Qiu scanned and added Liu Qingqing's WeChat account. The other party's profile picture was a photo of traveling, and next to it was the iron tower in Bali.

If the photo is not PS, it means that Liu Qingqing's family is indeed very good, because it is very rare for a family in a fifth-tier city to go abroad.

Like Liu Qingqing, if she has the backing of her family, she can indeed stick to the career she loves. Even if she fails, if she can't keep going, there is still a way out.

Liu Qingqing: "Then what should I do to prepare for scientific research now?"

Xu Qiu: "It's not urgent. First, finish the basic subjects of the freshman year. The grade points in the freshman year are still more important. When you are in the sophomore year, you join the research group. What is scientific research, you will naturally You will understand, if you still don’t understand at that time, you can come to me.”

Liu Qingqing: "Then usually, do student unions, clubs, etc. need to participate?"

Xu Qiu: "It depends on your own social needs. Anyway, I have almost never joined the student union or club."

Liu Qingqing pursed her lips, and suddenly asked, "Senior, do you have a girlfriend?"

Xu Qiu was caught off guard by this question: "...Yes."

Liu Qingqing ignited the soul of gossip: "Did you know each other in college?"

"Hmm..." Xu Qiu responded, and closed the door of the study, worrying that his mother, Bai Xiaofen, would hear it.

Liu Qingqing seemed a little confused: "What was love like in college? I haven't talked about it yet."

Xu Qiu: "You will know if you try it yourself. According to your conditions, there should be no shortage of suitors."

Liu Qingqing: "There are a few, but none of them feel that way. Let's not talk about this, let's talk about senior Xu Qiu and your girlfriend."

As a result, the topic in the second half was completely distorted, and the two of them were talking about Xu Qiu and Han Jiaying almost the whole time...

After chatting for more than 20 minutes, Xu Qiu discovered that Liu Qingqing had strict tutoring in middle school and had never been in a relationship, so she had some longing for love in college, but felt that her peers were too naive, so she couldn't find a suitable candidate. .

This is the price of maturity.

At this time, Liu Qingqing took out a small pink notebook from her pocket, opened it to a new page, and looked at Xu Qiu expectantly: "Senior Xu Qiu, please sign me. ...It would be even better if you could write a message."

"Yes." Xu Qiu took the small notebook, and complained in his heart: "I also sent a message... I am not a liberal arts student..."

Xu Qiu thought for a moment, and wrote down the school motto of Modu Comprehensive University: "Knowledgeful and dedicated, ask earnestly and think closely."

Then, Xu Qiu signed his own name and managed to deal with it.

Liu Qingqing, Hu Yao and Aunt Shu Yan didn't stay long and left after five o'clock.

After that, the days continued to be flat.

The days of not being able to appear in front of others passed quickly, and it was time to return to school in a blink of an eye.

Xu Qiu called Ctrip's customer service in advance to ask about the itinerary.

Then, he learned that the itinerary had been printed out by Ctrip, and he only needed to fill in the mailing address of the itinerary online, and it would be mailed after the return trip.

In addition, Xu Qiu had a very fulfilling winter vacation. Before leaving home, he got the latest results from the simulation laboratory.

The highest efficiency of binary single-junction devices based on Y series acceptor materials has reached 18.08%, successfully crossing the threshold of 18%!

Specifically, the acceptor material used was Y20 and the donor material was L6-Cl.

L6-Cl is based on the L6 material developed by Zang Chaojun and Lu Changjun's research group before, and a chlorine atom is introduced into the BDT unit.

The processing method used is spray coating, hot spin coating at 90 degrees Celsius, 0.25% volume fraction of DIO added, vacuum for 16 hours, no annealing, and non-solvent annealing.

This breakthrough, it seems that no bottlenecks have been encountered, and everything will come naturally.

But in fact, it is not completely a matter of course, but the big killer of time——

On the one hand, the simulation labs II and III are running at full power during the winter vacation; on the other hand, the simulation lab I will often come to the field, such as synthesizing these new donor materials. In order to get the materials faster, Xu Qiu always It is synthesized by hand.

Therefore, the actual groping time, if converted into real time, can reach more than one year.

Now, Xu Qiu's last "Science" article on stacked devices has now been submitted for review, and the second CNS-level work here, the L6-Cl: Y20 system, has begun to line up again.

For this work, Xu Qiu intends to vote for Nature.

However, after returning to school, I have to perform a performance, and try to synthesize L6-Cl and Y20 step by step reasonably.

On February 18th, Xu Qiu took a plane and returned to Shanghai.

Speaking of which, Xu Qiu didn't take planes very much before. There was a big reason that when he was a freshman and flew from his hometown to Shanghai for the first time, he developed an earache during the flight, and the pain was very severe. obvious.

And when Xu Qiu came home from Shanghai before Chinese New Year, he thought his ears would still hurt when flying, but he found that there was no serious pain.

Now, returning to school from his hometown again, Xu Qiu found that his ears started to hurt again during the voyage.

However, the degree of pain was not as severe as the first flight I remembered.

Xu Qiu speculates that it is probably because flying from south to north is more likely to cause ear pain, and flying from north to south is less likely to cause ear pain? Maybe it has something to do with air pressure?

It is a pity that there are too few samples, and only rough inferences can be obtained.
