I Have a Research Support System

In the class of Inorganic Functional Materials.

Xu Qiu stepped onto the podium and began to give a PPT speech.

Because there are a large number of candidates for this course, the time allocated to each student to report is very short, only five minutes.

Therefore, Xu Qiu chose his current work on Natural Energy and shared it with everyone.

Seeing the big LOGO of Nature·Energy placed there, Mr. Yu Bing, who was sitting in the audience, was a little jealous.

A group of postdoctoral fellows in their research group have published a lot of AM and JACS over the years, but it is still difficult to take a step closer to the level of a major sub-journal of Nature. Nature has published it.

The other students were relatively calm. Some of them happened to be present at the Organic Photovoltaic Conference organized by Wei Xingsi last time. Others who were not present at that time also learned about Xu Qiu's glorious deeds through the class group and circle of friends.

Xu Qiu's popularity is still relatively high, and the students received the most enthusiastic applause at the beginning and after the speech.

After all, people will be jealous of people who are stronger than them, but when facing someone who is too strong, it is not easy to feel jealous, but instead turn to admiration or admiration.

After successfully completing the report, Xu Qiu returned to the audience, listened carefully to the reports of others, and gave out scores.

Scores are given on a 10-point scale, with an interval of 0.5 points. All the scores given by Xu Qiu are distributed between 6 points and 10 points, roughly showing a normal distribution, and most of them are 7-9 points.

Xu Qiu gave himself a score of 9.5 points, and deducted 0.5 points to prevent himself from being proud.

The only 10 points was given to Mu Xue. The other party did a good job in terms of speech level and report content. It should be said that he was the only one among the students present.

After all, there is a professor at the Shanghai University of Magic in the family, and his start in scientific research is indeed much higher than that of normal families.

Of course, the other students who can enter the Shanghai Comprehensive University are not bad.

In general, more than 80% of the students' speech level is still above the excellent line, and they can express clearly without long pauses.

Only a few students may stumble when speaking due to introversion, nervousness, or insufficient preparation, and occasionally forget words.

As for the content, because among the students who choose courses, there are more first-year freshmen.

Therefore, the content of most of the students' reports is the work published by other brothers and sisters in the research group, or it is a report on the literature published by other research groups.

Xu Qiu was the only student who reported his own work. The other two were Mu Xue, who had the same preliminary work as him, and a third-year PhD student.

After all the students reported, Yu Bing took back each student's score sheet.

At this time, Xu Qiu used the system to copy these scoring sheets into the simulation laboratory like experimental materials. He mainly wanted to know his own scores in advance.

After looking through it roughly, Xu Qiu found that his grades in the scoring tables of all other students were all 10 points.

This was something he didn't expect, even at the beginning, Xu Qiu wondered if someone would give him a low score on purpose.

Now it's all right, the 9.5 points I gave myself have become the lowest score.

After deducting a minimum score and a maximum score, my score on the student side is 10 points.

At the same time, among the grades given by the teacher Yu Bing, Xu Qiu also scored 10 points, and he was the only one with 10 points.

Yu Bing gave Mu Xue a score of 9.5.

In other words, Xu Qiu's total score in the PPT report this time is a perfect score of 10, and the problem of getting an A in this course is basically not a big problem.

This is well-deserved, as Xu Qiu's speech ability has reached a very high level after several group meeting reports and the training of the conference report.

In addition, with the improvement of the system's authority level, some new functions that have nothing to do with the experiment have also been developed by Xu Qiu. Copying the scoring table is just one of the small functions.

Once Xu Qiu wanted to try it out, and wanted to copy Han Jiaying into the simulation laboratory.

It turned out that it was really successful, the school girl was restored 1:1 in the simulation laboratory, and there is still a sense of touch...

Then, Xu Qiu...

Unfortunately, he found that the copied school girl couldn't move...

Otherwise, he really wanted to copy a few more people in to help him with experiments.

Fortunately, the integration of the system can basically achieve perpetual motion now, but it doesn't matter, there are enough simulation experimenters.

Friday, which happens to be Christmas Eve.

Because Wei Xingsi stayed in the beautiful country all year round, he still retained some traditions in the beautiful country.

For the more important festivals in the West like Halloween, Christmas Eve, and Christmas, he will give benefits to the group, such as one-third of the day off, that is, one night, and treats to go out to play and so on.

This time is no exception. Wei Xingsi said that he will treat guests to dinner in the evening and fund the team building of the research group.

However, he didn't come here himself, he only provided funds, probably to accompany his family or other important people.

Although a few undergraduates didn't work in the lab much because of the exam week, they were very active when they heard about the team building activities.

The business district near the Shanghai University is very large. This is also an important business district in Shanghai, Wujiaochang, and there are hundreds of restaurants around it.

The most important thing is that there will always be old restaurants closing down and new ones opening up, so you don't have to worry about finding new restaurants to eat.

Finally, after careful selection by Wu Feifei and Tian Qing, they found a newly opened Feast Teppanyaki, which is said to have good reviews.

But because it was Christmas Eve and Friday, online queuing was not open, so we could only line up on the spot.

When they arrived at the scene, everyone found that there were a lot of people queuing up, and they finally got in after waiting for more than an hour.

The price here is still on the high side, and the portions are relatively small.

However, it is rare for everyone to come out to have a meal together, and they didn't save too much, so they decided to match the meals according to the per capita meal standard of 100 yuan.

According to the usual practice, the standard for reimbursement of the meal standard on Teacher Wei's side is 70 yuan per person.

Xu Qiu and Wu Feifei made a little calculation and decided to reimburse 70% from Teacher Wei and 30% from the team building fund in his own group.

Now Xu Qiu and the others have reconnected with Shencheng Optoelectronics, and have received a few bonuses for posting articles. The funds for team building are quite sufficient, and there are thousands of dollars left unused.

In fact, 100 yuan per capita is not too expensive in Shanghai. If you only order dishes without staple food, you may not even be able to eat enough.

Especially the new third-year undergraduate student in the group, Deng Hu is very strong, and his appetite is also amazing.

When others go to the cafeteria to eat rice, they need one tael or two taels, but Deng Hu needs five taels and a catty. A meal can do a catty of rice, and there are three dishes to accompany it.

So, Xu Qiu thoughtfully ordered a large portion of fried rice for Deng Hu.

The dishes here are pretty good and more refined.

A chef with a white tall hat helped to process the ingredients on the spot, and then baked, cut and sent them to everyone.

...

Half an hour later, everyone had almost eaten, patted their stomachs, and began to discuss where to go next.

The usual group building and entertainment activities for college students and graduate students are actually relatively limited.

Basically, it is eating, playing board games, or mahjong, 80 points, or bars, KTV.

The friends in the research group are basically good babies, so no one suggested going to the bar.

Of course, it may also be related to the high consumption in bars, and graduate students are generally relatively poor.

When Xu Qiu was an undergraduate, Tao Yan took him to a bar once, and saw that the drinks on the menu were basically 50+, or even 100+.

And the names are also very literary, such as Pretty in Pink, Green Grasshopper, Long Island Iced Tea, Angel's Kiss, Persian Cat's Feet...

Xu Qiu casually ordered a cup of Long Island Iced Tea. Judging by the name, I think it might be like iced black tea?

As a result, I took a sip of it, and it felt sweet and unpalatable, and I couldn't accept it.

I don't know if this cocktail recipe doesn't suit me, or the bartender's technique is not good enough.

Later, when he was graduating from undergraduate, Xu Qiu went to a bar with Tao Yan and a few other classmates.

That time I drank an unnamed liqueur made by the bar itself, a pot of 168, the taste was not bad, but the stamina was a bit strong, a bit on the top.

The four of them drank three pots, and they were quite normal in the bar. When they went out, they were blown by the wind, stumbling around in an instant, and in the end they basically walked back to the dormitory at an angle.

After some deliberation, everyone finally voted and chose the board game from the board game and KTV.

At this time, Wu Feifei said: I won't participate when I have something to do. You can go play board games. For reimbursement, Xu Qiu, you can contact Mr. Wei directly, or you can report the amount to me.

As soon as she finished speaking, she received everyone's attention and scrutiny.

Xu Qiu also felt that during this time, Wu Feifei's behavior was indeed a bit strange. Like when he was dealing with PCBM customs clearance, Wu Feifei said that she was busy, but she was actually busy replying to WeChat messages, not busy. Write articles or do experiments.

Moreover, when other people passed by Wu Feifei, she would subconsciously cover the phone screen with her hands.

At that time, Xu Qiu speculated that there was a high probability that Senior Wu Feifei was going to leave the order.

It now appears that my judgment at the time was likely to be correct.

There are now 13 people in the research group, except for Xu Qiu and Han Jiaying who are a couple, Duan Yun and the new undergraduate student Yin Houlang who have girlfriends, everyone else seems to be single.

Tian Qing occasionally paired up with a boy from another research group on the fifth floor of Caiyi, but according to her: We are just ordinary friends.

In fact, at the postgraduate stage, especially girls, these things should really be considered, and if you don't think about it, you will be left behind.

It's quite funny to say, now, including in the past, many parents were afraid that their children would fall in love when they were in middle school, but during college, they wished that they could have a girlfriend right away, bring them home during the Chinese New Year, and then get married after graduation kind of.

Going deeper, domestic families, especially families with a relatively low level of education in the previous generation, generally lack education in areas such as love, sex, money, death, and career planning, and school education is biased towards exams, so it is difficult to make up for this. aspects of knowledge.

Although as time goes by, even those who have not received these educations will gradually understand these principles in the severe beatings of society.

But there is only one life, and some key nodes have passed, and there is no chance to start again.

For example, some social events that have caused widespread heated discussions: Unexpected pregnancy of minors/college students, Minors reward anchors with large sums of money, Minors recharge games and spend all family savings, College students take fruit photos Borrowing, Because of some trivial things, such as failing exams, being broken up and easily committing suicide...

In essence, it corresponds to the lack of family education.

However, this is a limitation unique to that generation.

Even if the people who eat melons on the Internet are having a great time discussing it, pointing out the country from the moral high ground: This is the wrong thing, that is the wrong thing, it is of no practical use.

Similar situations will always happen, this is the scar of the times, only time can wash away all these.

Of course, it is still necessary to use the news to report these things, and it may be able to save some lost lambs.

Although the effect may be weak, treating the symptoms but not the root cause, it is still a good thing to save one person.

In fact, every generation has its troubles. Because of a certain incident, the education level of that generation is generally relatively low, which has caused many tragedies.

As for this generation, the level of education has improved, but they have also ushered in introversion and faced the same severe test.

After Wu Feifei said that something happened, Yin Houlang also said that he would not participate because of something. In the end, there were only 11 people left to play the board game.

After walking for a few minutes, everyone came to the familiar maid board game shop without a maid on Daxue Road.

Now the new undergraduates in the research group are already familiar with everyone, and they are not so famous.

Yu Ya seems to be a board game enthusiast, and took the initiative to give everyone a board game called Avalon.

Then, I soon got a response from Mo Wenlin, who is also a board game enthusiast, and no one else raised any objections.

Yu Ya gave a brief introduction: The standard game of Avalon is 7 players, but 10 players can also play. There are 11 of us, just one God, and 10 players. The background of Avalon's story comes from Legend of King Arthur , a bit similar to werewolf killing, but the biggest feature of Avalon is that civilians will not die. It is divided into two camps, the blue side and the red side. The blue side aims to complete the task and protect the archmage Merlin; The goal is to sabotage the mission and assassinate Archmage Merlin.

Mo Wenlin added: There are five missions in total, which is equivalent to voting for the best of 5 rounds. Of course, the premise is that Merlin can't be exposed too early and be discovered by the red team.

Yu Ya continued: In a 10-player field, the blue team has Merlin, Percival, and four of Arthur's loyal servants, and the red team has Mordred, Morgana, Oberon and assassins, except Arthur's Except for loyal ministers, everyone has special abilities.

Mo Wenlin took out each identity card from the box, spread it out one by one, and explained to everyone:

Merlin on the blue side can initially see all the characters on the red side except Mordred on the red side;

Piscival on the blue side can initially see Merlin on the blue side and Morgana on the red side, but cannot confirm their respective identities;

The loyal servant of Arthur in the blue side has no special abilities, and is equivalent to the villagers in Werewolf Killing;

Mordred on the red side, Merlin on the blue side can't see him;

Morgana from the red team can pretend to be Merlin from the blue team to confuse Percival from the blue team, because Percival usually wants to reveal his identity to lead the team;

Oberon on the red side can't see other red sides, and other red sides can't see him, similar to the hidden wolf killed by werewolves;

The red team's assassin, after the blue team's 3 successful missions, decides on his own to choose a player who may be Merlin to assassinate. If he chooses, the red team wins.

I'll be the god in this game, and Yu Ya will come in the next game, how about you?

Okay. Yu Ya nodded.

After listening to the rules, the others were a little confused.

Because the names involved are all crooked nuts, if they are called Zhang San, Li Si, Wang Wu, or Lan Yi, Lan Er, Hong Yi, and Hong Er, it will be much easier to understand.

However, everyone present here has been educated for more than ten years, and their ability to touch new things is relatively strong.

After two games, everyone has initially mastered the rules of the game and started the formal competition.

In the third game, Mo Wenlin was God, and the blue team had completed three missions.

Seeing that the blue team is about to win, the red team can only rely on the assassin to save the field.

At this moment, Xu Qiu turned over his hole cards: Flop, I'm an assassin...Which one of you is Merlin?

While speaking, Xu Qiu's eyes were also scanning the other people around him.

He noticed that Tian Qing seemed a little nervous, but the other party might also be showing off his acting skills, holding Arthur's loyal servant and trying to pretend to be Merlin to block the knife.

Originally Xu Qiu was a little suspicious of Tian Qing, but now seeing her acting so obviously, her suspicion towards her has been greatly reduced.

Xu Qiu turned to look at the junior girl next to her, and said, Meilin, it's you, you already know my identity, and you've been stepping on me.

Han Jiaying sighed lightly: Hey, you discovered all of this.

Mo Wenlin said, Assassin, have you chosen to assassinate Han Jiaying?

In this mode, the assassin makes the assassination decision by himself, and cannot communicate with other red team teammates, nor can he know the hidden identity of the red team Oberon, so the difficulty is relatively high.

Although Xu Qiu could cheat through the system and look at other people's hole cards, it would be meaningless to do so.

This kind of game still relies on one's own logical reasoning, and only when the correct result is obtained will one be satisfied.

Xu Qiu shook his head. He didn't look like Mei Lin in the state of his junior. She might also be a loyal minister, but because he knew him better, he deduced that he was popular.

On the court, Sun Wo is the well-known Percival.

The other two Minghong teammates are Deng Hu and Wu Shengnan.

In the end, Xu Qiu was entangled between Chen Wanqing, Duan Yun and Xu Xinjie:

Xu Xinjie's speech was relatively sloppy, and the voting also followed the crowd. It may be because of her personality, or because of her loyal ministers. There is no information.

Duan Yun is a bit like Oberon of the red side, whether speaking or voting, he has been quietly helping the red side with work. Of course, he may be a fake loyal minister who can't distinguish the situation, but there is a high probability that it is not Merlin.

Chen Wanqing often interacts with Sun Wo intentionally or unintentionally, as if passing a message to Percival from the blue team, saying that I am Merlin, I am Merlin, don't mistake me, she is more likely to be Merlin.

After struggling for a while, Xu Qiu finally chose Chen Wanqing: Sister, you are Mei Lin.

Mo Wenlin said: Assassin, do you choose to assassinate Chen Wanqing?

Xu Qiu nodded: Sure.

Mo Wenlin said: Chen Wanqing flopped Merlin, the game is over, and the red side wins.

Chen Wanqing, Han Jiaying, and Tian Qing immediately lowered their faces, with expressions of regret.

Deng Hu, Wu Shengnan, and Duan Yun smiled.

Sure enough, Duan Yun was the hidden Oberon who was not so obvious.

Chen Wanqing said, Hey, Xu Qiu, how did you find me...

Tian Qing and her junior said in unison: I thought you would identify me as Merlin.

Xu Qiu laughed. He deduced this based on his strength. He didn't cheat, so he had a sense of accomplishment. He saved the red team from the fire and turned defeat into victory.

After all, there are six people on the blue side, plus the hidden Oberon on the red side, there are seven unknown identities in total.

Apart from Ming Pai Xavier, himself and two Ming teammates, Xu Qiu had to choose a real Merlin from the remaining six people, which was quite a test.

...

The happy time is always short, and it is Sunday again in a blink of an eye.

At 1:20 in the afternoon, Xu Qiu came to Caiyi early.

He received a message from the customs clearance company claiming that the package for PCBM had been delivered.

Xu Qiu went to the concierge to pay the postage. After receiving the package, he took out the PCBM bottle, put it in the glove box, and copied a copy to the simulation laboratory.

Then, he returned to his desk, opened the draft file of Science, and continued to fill in the content.

Not long after, other friends from the laboratory arrived one after another.

Mo Wenlin approached Xu Qiu and said, Should we still make devices today? During this period of time, I have made four batches of stacked devices, but the highest efficiency is only 15.35%, which is higher than your previous 15.31%. 0.04%, hey... This is equivalent to standing still, how can we continue to improve?

Xu Qiu thought for a while and suggested: New PCBMs have arrived today. You can use this batch of PCBMs to reconstitute the solution for a try. Maybe the performance of the device will be improved.

Mo Wenlin responded: Well...Okay, let me try.

At present, the efficiency of the IDIC-M/IEICO-4F stacked device in the simulation laboratory has been optimized to 15.91%, which is very close to the 16% mark.

However, in reality, the efficiency of stacked devices has been unable to break through. Even if the known optimal conditions are applied simultaneously, the gap with that in the simulation laboratory remains at about 0.56%.

Xu Qiu was also a little surprised by this.

Although there is usually a gap between the device performance of the actual reality and the simulated laboratory, the gap is usually between 0-0.3%, and generally does not exceed 0.5%.

This time there was a gap of more than 0.5%. Xu Qiu didn't think it was because of Mo Wenlin's problems in the experimental operation, but more likely to be a problem with the experimental drugs.

Because the PCBM in the simulation laboratory can never be used up, and the operation of the operators is absolutely standardized, the state of the medicine is relatively good.

In reality, the state of drugs in the laboratory will deteriorate as the use time becomes longer.

It is also easy to understand that if it is a medicine exposed to the air, some will react chemically with oxygen, water, and even carbon dioxide in the air.

There are also some medicines, such as inorganic salts and organic monomer materials, which will also be damp and absorb water.

If it is a medicine stored in a glove box, although it is difficult to encounter water and oxygen under the protection of high-purity nitrogen, various impurities will also be introduced during use.

Because it is difficult to ensure that every experimental operation is completely standardized, there will always be operational errors.

And, sometimes people don't even know they made an operational error.

Just like no matter how good the security measures are, there is also a certain probability that others will like to be a father.

In addition, the number of people in the laboratory is very large, and there may be a situation of reagent sharing.

No one knows what other people have done with this reagent, and whether the reagent has been contaminated.

For various reasons, the remaining PCBM may have been doped with various reagents, including perovskites and non-fullerene acceptor materials.

After all, there are only a few spatulas in the glove box, and people often use them mixedly. Even if they are wiped clean with lens cleaning paper before and after each use, there will always be residues of the previous medicine. Over time, the purity of the medicine will drop very much. many.

This is why a small amount of medicine, such as 100 mg, needs to be transferred to a small vial for a large package of 1 gram or 5 gram such as PCBM, and then taken from the vial.

Because once the medicine in the small bottle is contaminated, it can be discarded directly, and if all the large bottles are contaminated, the cost of discarding is a bit high.

After talking about PCBM, Xu Qiu continued to order: By the way, you also need to take over several new materials from Wu Shengnan.

Ah— Mo Wenlin said with a bitter face: Wouldn't it be necessary to rebuild the array of laminated devices...

During this period of time, she has been doing a lot of equipment, and she has been exhausted by Xu Qiu's arrangement all day long, but there is no result. Because she can't form effective positive feedback, she is a little sabotaged.

Seeing this, Xu Qiu dragged the Science draft file on the computer screen to the top, which is the column of the article title and author.

Look here. Xu Qiu pointed to the second author of the article.

Seeing that she was the second author and Wu Shengnan was the third author, Mo Wenlin immediately became excited: Xu Qiu, I'm going to make a device, Sun Wo, I, I, I want to... make a device, wait for me, let me go first. I have a solution.

Okay, you go. Sun Wo had already entered the glove box, but when he heard Mo Wenlin's call, he retreated directly. He is more Buddhist now, and anyway, he knows that he probably won't achieve any big results, so he plans to Paddle water and get a diploma.

Now Sun Wo's state is to listen to Wu Feifei's command in the general direction. At the same time, if there is any experimental arrangement on the organic photovoltaic side, he will not fight or grab it, and it happens to be free.

Even if Mr. Wei asked later, he could still make an excuse: It's not that I want to fish, I was forced. It's Xu Qiu and the others who are too powerful to grab them.

In the simulation laboratory, in addition to the IDIC-M ternary/IEICO-4F binary system, several near-infrared non-fullerene materials developed by other research groups, including COi8DFIC materials, have been synthesized and replaced The IEICO-4F material in the original top battery was removed, and the performance of the laminated device was simultaneously explored.

Judging from the preliminary exploration results now, the device efficiency of several new systems has not surpassed the original IEICO-4F system for the time being.

It's normal, after all, building an array of stacked devices is a troublesome thing.

For ordinary single-junction devices, the optimal results may be obtained in a day or two in the simulation laboratory, but the current stacked devices may take a week or two to optimize the conditions.

However, although the systems based on new materials did not break through the original IEICO-4F system's highest record of 15.9%, the several materials did not disappoint Xu Qiu too much. The results of preliminary explorations generally showed that the efficiency exceeded 14%.

The best system is the COi8DFIC that Xu Qiu was very optimistic about before.

With J4:PCBM:IDIC-M as the bottom cell and PCE10:COi8DFIC as the top cell, the device efficiency reaches 15.67%.

According to the current situation, it is only a matter of time before the device efficiency catches up with the original IEICO-4F system, and it is very likely that it can break through 16%.

Speaking of which, if Xu Qiu put together four or five new multilayer systems, each of which can be compiled into an article, according to the current organic photovoltaic field with a maximum efficiency of only 13.5%, it can basically be beaten.

If these jobs are released, in the field of organic photovoltaics with the highest 13.5% at present, they will basically be hanged, and they can be published in AM, JACS, EES, NC in turn, and even a major sub-journal of Nature.

However, Xu Qiu did not intend to do so.

At Xu Qiu's current stage, work like AM is of little significance to him, it belongs to the kind of casual posting, and impacting a CNS main publication is what he has to do.

Moreover, if so many articles are really published, even if his device efficiency reaches 16% or 17% in the future, it is estimated that he may not be able to publish CNS.

Because the novelty was apportioned to other similar articles.

Unless the differences between the several systems made are very large, or the gap in device efficiency is widened again, it can reach 18%, or even more than 20%.

In addition, even if you really plan to sell all these jobs, you still need people to complete them. Doing experiments and writing articles all require energy.

The situation that Xu Qiu is now facing is that he has a good job, too many good ideas, but the research team is short of manpower.

The senior is graduating soon, so I can’t count on her. The junior is busy synthesizing PTQ series donor materials. Wu Shengnan also has his own receptor synthesis task. Mo Wenlin was originally working on the ternary system, but now she is abducted by herself to laminate The device came, but she only had one person and couldn't eat so many systems.

Xu Qiu thought that he also needed to cultivate some backup force for himself, and it would be best to recruit some newcomers.

Next year, when Dr. Chen Wanqing and Duan Yun graduate, and Han Jiaying comes in with a master's degree, the group can also recruit a doctorate, who can take over the class of the senior.

But there can only be one Ph.D. Now that there are so many people in the group, it is unreasonable to let Teacher Wei go out to borrow a place.

Perhaps, you can add more burdens to the two new undergraduates?

Isn't Yin Houlang planning to go abroad? Although foreign countries value recommendation letters more, for colleges and universities, articles are hard currency. It can be said that articles are letters of recommendation written by themselves.

If an undergraduate publishes an article on Nature, basically all schools in the world will rush to ask for it.

In fact, if you can post an AM work as an undergraduate, as long as your English is not too bad, you can pass the corresponding IELTS, TOEFL, and GRE exams, and it is relatively easy to go to the top ten prestigious schools in the world.

After all, I can post AM, not to mention the ability of experiment, the ability of writing articles alone must be very strong.

Even if the field of study changes, the ability to write articles will remain.

However, Xu Qiu thought about it again, Yin Houlang and Xu Xinjie, they are only sophomores, and they are still children.

Shall we destroy them?

At this moment, Wei Xingsi suddenly appeared at the door of 216: Xu Qiu, come to my office.

Xu Qiu asked, What's the matter?

Wei Xingsi explained: There is a master student from Eastern Expedition University who plans to study for a Ph. If it is up to you, come and have a look together, today will be regarded as an interview.

Okay. Xu Qiu's eyes lit up, it was true that when he fell asleep, someone gave him a pillow.

With the continuous publication of high-quality articles in the group and the timely maintenance of the research group website, the reputation of the group has already been spread.

Wei Xingsi often receives emails from some third-year master students expressing their intention to come to study for a Ph.D.

All the applicants were students from other schools, because the direct Ph.D. students of this school, that is, Han Jiaying's class, have already confirmed their supervisors, and the chance of poaching them is relatively small.

However, Mr. Wei did not see a satisfactory application from the previous applications, so he rejected all of them.

At that time, Wei Xingsi believed that the requirements for screening resumes were not high, and there were only three points.

Read the article first, and it is required to have published at least one article in SCI District 1 or District 2 as the first author.

Because the requirements for publishing articles in the third and fourth districts are different from those in the first and second districts, not to mention the experimental work, but in terms of language alone, the language requirements for articles in the third and fourth districts are much lower than those for articles in the first and second districts.

If they have no experience in posting articles above the second district, most of them still need to cultivate their ability to write high-end articles from scratch, which is a very troublesome thing.

Even with a good level of English, it takes a lot of time.

For example, for Sun Wo's ACSAMI, it took more than a month to write the article, almost two months.

And the same job to Xu Qiu may only take less than a week, and the work efficiency is more than four or five times worse.

Secondly, look at the background, that is, the school during the undergraduate and master's periods.

Wei Xingsi thinks that at least one of them must be 985, preferably 985 for undergraduates.

Finally, looking at the English score, CET6 is required to reach 500+.

This is also the minimum standard set by the department. If the English is too poor, it will be very painful when editing the article in the future.

However, too many people rejected some time ago, which also made Wei Xingsi discover that it might be a bit difficult for students from other schools to meet the three requirements at the same time. It's embarrassing.

Therefore, Wei Xingsi lowered the standard, and two of the three should be achieved.

The candidates this time only met two of the conditions.

The other party is from Dongfa University. Although he is not 985, he is excellent in other aspects. During his master's degree, he published an AFM review and an ACSAMI. He received a national scholarship, and his English score was 600+ in CET.

Moreover, the Materials Department of Eastern Expedition University and Modu Comprehensive University have relatively close cooperation, and they have passed many talents here all the year round. For example, Wu Feifei in the group is from Eastern Expedition University. Wei Xingsi also has a natural affection for students from Eastern Expedition University .

In addition, Dongfa University happens to be in Shanghai, so it is more convenient to come here.

Therefore, Teacher Wei asked the other party to come over on weekends to meet and chat.

It is worth mentioning that, from a bachelor's degree to a master's degree, one usually needs to take the postgraduate entrance examination or guarantee postgraduate entrance examination to enter a university, which is relatively troublesome and has a certain threshold;

On the other hand, admission from a master’s degree to a doctor’s degree is relatively simple. Usually, the evaluation system is adopted. There may be only interviews and no exams.

For example, if you contact the Department of Materials of Shanghai Comprehensive University, if you contact the tutor, and the tutor is willing to ask you, there is a high probability that you will be able to come in.

Faculties and departments are relatively easy to talk about. The only rigid requirement is the English CET6 score, which is generally above 500 points now.

Of course, due to introspection, many postgraduates regard Ph.D. as employment. The school’s recruitment standards for doctoral students are also increasing year by year, and some master’s applicants with relatively poor conditions will also be eliminated.

For example, when Wu Feifei applied for combined master-doctoral studies, she found that she had not enough places for the combined master-doctorate programs that she could not use up in previous years.

Later, she successfully transferred to a Ph.D., and several master students who planned to continue their Ph.D. studies were eliminated and could not transfer to a Ph.D.

According to Wu Feifei, at the time of the evaluation, although the interview results were used as the standard, it mainly looked at the articles published during the master's period to determine the final ranking.

Generally speaking, in the same school in China, it is best to get a Ph.D., the threshold is very low, and basically only need an interview, followed by a master’s degree, which requires postgraduate entrance examination/guarantee postgraduate entrance examination.

For example, graduates of Tsingbei University also have the highest gold content.

Therefore, if students in the third year of master's degree plan to continue to do scientific research, and the current research group or school is relatively average, they will jump to a higher and better platform.

Similar to: 211 masters go to 985 doctors, 985 masters go to C9 doctors, and C9 masters are either combined with masters and doctorates, or they may go abroad.

If the intention to continue their studies is confirmed, master graduates usually contact their tutors in advance.

Because once the contact is late, good tutors are basically snatched up, just like undergraduates looking for a job, if they delay until the second semester of their senior year and start looking for a job on the eve of graduation, it will be more difficult to find the job they want.

Moreover, if a master's student chooses to change schools and research groups, the direction of specialization during the master's and doctoral periods will most likely not be exactly the same, and he needs to enter the research group in advance to give himself and the research group a buffer time.

Including familiarizing with the environment of the research group, reading literature in related fields, learning how to use various new experimental equipment, and handing over work with the predecessor.

This is the unspoken rule of the scientific research circle.

For example, Chen Wanqing and Duan Yun in Wei Xingsi's group, because they have already met the graduation requirements, so Wei Xingsi basically doesn't care about them now.

However, there are also research groups that squeeze the students to death. The tutors will not give the students freedom until the last moment, before they sign the graduation proposal.

Graduating in July, I have to work until the end of June before letting me go...

This is a bit over.

If this is the case, most of the students will choose not to communicate with their mentors after graduation, and there is a high probability that they will not continue to do scientific research.

Because it has been beaten.

Unfortunately, the status quo is that the proportion of such mentors is not low.

Xu Qiu reckoned that at least 10% of the domestic market.

Like landmines, they are buried in major colleges and universities.

PS: The third-year undergraduate student in the research group is Deng Hu, and the teacher of HKU and PCE11 materials is Yan Hu. Because the names are similar, I made mistakes several times before.

PS2: Ten thousand changes again, ask for a monthly ticket, and there is still more than one hundred tickets to break the thousand.
