I Have a Research Support System

Although the laboratories of Wei Xingsi's research group have moved to Jiangwan, the group meeting on the first day of construction was still held at the Handan campus.

On the one hand, it was because Wei Xingsi’s office hadn’t moved there yet, and on the other hand, it was also because the students’ dormitories were also located in the Handan campus.

Regarding the dormitory, Wei Xingsi had already applied to the department, and put forward his own request: Move the dormitories of several graduate students in the group first.

The department said that it has submitted its opinions to the park and needs to wait for the results.

However, for Xu Qiu and the others, no matter whether the dormitory can be relocated at the same time, they will face some inconvenient problems.

If you can’t move the dormitory to Jiangwan, you have to take the school bus to and from Handan and Jiangwan every day. The commuting time for a single school bus is about a quarter of an hour, plus the time for waiting for the bus and walking, it will cost an extra one a day. Hour.

And if the dormitory is moved to Jiangwan, he will also face the problem of having to attend classes in Handan.

Because the major professional courses of the departments in this semester are all offered in the Handan campus, so they have to go to both Handan and Jiangwan.

In the final analysis, it was because the other research groups of the Materials Department moved too slowly. If all of them moved there, the departments could offer all the courses in Jiangwan.

This is probably the painful period during the school's transformation.

In fact, this is also a manifestation of the contradiction between individuals and groups.

When a group considers a problem, there is a high probability that it will make a decision in the direction that is best for the entire group at the moment, and in this process, it will inevitably damage the interests of the individual.

Just like the incident of the new national standard electric car, some people may have just spent two to three thousand soft sister coins to buy a non-national standard electric car, but they didn’t drive it for a few months, and the new national standard was launched, and the car was directly confiscated.

Or bought an electric car that was still the national standard at that time, but after a few months or a year, the national standard changed...

For another example, statistical data show that since 2000, the average growth rate of broad money M2 of florists has been around 15%.

In layman's terms, it means that nearly 15% of the currency is issued every year.

In other words, if the cash on hand is not invested or consumed, but just held in hands, it will depreciate at a rate of nearly 15% per year.

But the people at the bottom may not feel that inflation is as serious as 15%.

This is because most of the excess currency has flowed into real estate and some white horse stocks before.

As a result, the value of core assets such as real estate and Mao stocks has increased tenfold, hundredfold, or even a thousandfold in recent years.

The reason why the bottom layer does not feel the substantial inflation is because it is averaged, just like the average income of the richest man and I is over 100 million.

There is a saying called deflation of the poor, inflation of the rich, which expresses this phenomenon.

In fact, before 2000, the growth rate of M2 was even higher than 15%.

Therefore, at that time, there was a saying of 10,000 yuan household. Many people thought that 10,000 yuan could realize wealth freedom and provide for the elderly with peace of mind. However, it turns out that 100,000 yuan is not necessarily enough for retirement...

Or, now I think that 30 million cash plus a house can realize the freedom of wealth in the first-tier cities, but after 30 years, I may find that it is not enough...

Because 0.85 to the 30th power is equal to 0.00763, based on the M2 growth rate of 15%, the average purchasing power of 1,000 soft sister coins after 30 years is equivalent to the current 7.6 soft sister coins.

Even if the M2 growth rate is 10%, calculated according to the 30th power of 0.90, it is equal to 0.0423, and the average purchasing power of 1,000 soft sister coins after 30 years is equivalent to the current 42.3 soft sister coins.

However, having said that, for individuals, they may not like inflation, but like deflation. They all hope that they can lie down and do nothing, and the money in their hands will become more and more valuable.

But it is precisely because individuals will spontaneously tend to self-interest without external force, so from the perspective of the group, only inflation can motivate people to work hard, create value, and consume to the greatest extent. , and then promote the development of the entire group.

In the afternoon, everyone in the research group except Duan Yun and Chen Wanqing took a taxi to the Jiangwan campus together.

Because today is Sunday, there is no school bus, so a group of 12 people took three buses.

From next week, that is, two weeks before the start of school, the school bus will be open for the whole week from Monday to Sunday.

Everyone arrived at Jiangwan Laboratory and began to assign work.

In the end, it was decided that Xu Qiu would lead a group of people mainly responsible for the debugging of the glove box, and Wu Feifei would lead another group of people mainly responsible for the secondary debugging of other equipment.

The current three-row glove box has only one shell, which is empty and contains nothing.

Moreover, when returning to the factory for processing, the glass of the glove box was removed for reprocessing.

In other words, the atmosphere inside the glove box is now air.

Therefore, first of all, it is necessary to clean the three rows of glove boxes, convert the atmosphere inside them into nitrogen, and reduce the water and oxygen content to the normal range before the next experimental operation can be carried out.

This step requires the consumption of a large amount of nitrogen.

Fortunately, Sun Wo was prepared and ordered four bottles of high-purity nitrogen in advance. In this way, adding the original four bottles of high-purity nitrogen in the laboratory, there are a total of eight bottles of nitrogen, which should be enough to clean three glove boxes.

It is worth noting that although the centralized gas supply pipeline was installed before, there are two kinds of gas pipelines reserved, namely nitrogen and nitrogen-hydrogen mixed gas.

But in actual installation, the two pipelines are the same, that is, they can be mixed.

After all, there is only 5% volume fraction of hydrogen in the nitrogen-hydrogen mixture, and 95% volume is nitrogen, which is not much different from high-purity nitrogen in terms of physical and chemical properties.

Because of this, the four steel cylinders that are kept in the laboratory can all use high-purity nitrogen in normal times.

Only when it is necessary to regenerate the glove box, change one of the bottles of high-purity nitrogen to a nitrogen-hydrogen mixture.

Such an operation can reduce the frequency of changing gas cylinders by 33%, improving work efficiency to a certain extent.

After 20 minutes, the cleaning is complete.

The water and oxygen content inside the triple row glove box is below 100ppm.

Among them, the relatively small new spin-coated glove box on both sides was cleaned with only a whole bottle of high-purity nitrogen, while the old glove box in the middle, which is relatively large for storing reagents, was cleaned with two whole bottles of high-purity nitrogen. Finish.

Next, it is physical work, and various reagents and instruments need to be put back into the glove box.

Xu Qiu was in charge of directing, two boys, Sun Wo and Fan Wentang, were in charge of the work, and the other girls assisted.

The glove box for storing reagents in the middle is mainly imported into balances, heating and stirring tables, and various medicines and reagents;

Organic spin-coating glove box, mainly imported into heating homogenizer, scraper coating machine, and heating and stirring table;

Perovskite spin-coating glove box, mainly imported into ordinary glue homogenizer, and heating and stirring table;

No way, there is only one glue homogenizer with integrated heating function, so it is given priority to the organic photovoltaic team.

In this regard, Wei Xingsi said that the cost of the equipment in the group has bottomed out, and he plans to go to Gong Yuanjiang to play the autumn wind, and then PY a heating glue machine, and return them after the project funding is applied for.

In the end, after spending half an afternoon, Xu Qiu and the others finally allowed the three-row glove box to function normally.

The remaining work is to prepare standard devices, explore processing conditions, and make the entire device laboratory run normally as soon as possible.

The task of exploring organic photovoltaic devices was handed over to Mo Wenlin by Xu Qiu, and he returned to the 401S student office to start his own work, that is, to write articles for Y2-Y5.

For the four Y-series materials, Xu Qiu didn't plan to publish too many articles. He planned to follow Wu Shengnan's practice and submit two AM-level articles.

In fact, the efficiency of the Y4 system with the best performance can reach 14.6%. If you work hard and increase the efficiency, you may have the opportunity to hit the big sub-journal of Nature. However, Xu Qiu did not do so for the same reason as Wu Shengnan. Yes, he already has a system with 18% efficiency in his hands, and now he just wants to get rid of the preliminary work quickly.

In the end, Xu Qiu's plan was to publish one article for the Y2 system and another article for the Y3-Y5 system.

Among them, Y2 uses the ICIN end group, which is equivalent to the standard sample;

The end groups of Y3-Y5 adopt three derivatives of ICIN, which is equivalent to further optimization, and it also makes sense from the story.

Speaking of which, during the vacation, Xu Qiu originally planned to write an article, but later he was too busy to sprint for efficiency, so he didn't have time to write.

However, for Xu Qiu now, even writing an article of AM level is a matter of minutes for him.

In the case of complete data, an article can be written and submitted in about a week.

...

two weeks later.

The Jiangwan 522 laboratory was operating normally, and the one-month shutdown that Wei Xingsi had expected did not happen.

Even, when Mo Wenlin made a standard device for the first time, she was surprised to find that the performance of the device was actually higher than the previous highest performance.

For this reason, Mo Wenlin also went to Xu Qiu to show off: Xu Qiu, the efficiency of this batch of H22:ITIC standard devices I have achieved is 10.57%, which is higher than the highest value you reported before.

Xu Qiu smiled without saying a word, and gave her a look to let her experience it by herself.

In fact, the higher efficiency of the standard sample is not only due to the use of glove boxes, but also related to the increasingly perfect processing technology of organic photovoltaic devices in the research group.

There is a big difference between materials science, which is biased towards applied science, and basic subjects such as physics and mathematics.

In the latter case, if a correct proof process is given, then others can repeat the proof process.

But for the former, even if an optimal material is given, it will be useless if other people do not do the workmanship well.

This is why the performance results reported by different research groups may be quite different for the same system.

For example, Xu Qiu told a small research group about the L6-Cl:Y20 system with the best performance and an efficiency of 18%.

After the small research team learned about this system, it may take several months to find out the efficiency of more than 16%. If the efficiency wants to reach 18%, it depends on fate.

In addition, Sun Wo and Wu Feifei cannot repeat the 12% efficiency of tin-based perovskite, which is also the reason.

At the same time, Xu Qiu secretly helped the research group optimize the experimental conditions, but did not choose to make it public, but hid his credit and fame.

Apart from not wanting to expose the system, another reason is that Xu Qiu doesn't know what other people will think when they find out about this...

Wei Xingsi might be happier. Moving the laboratory once did not have a big impact on the experiment process. It just allowed the students to take an extra two weeks off, so they won't lose money.

And other people in the laboratory, if they haven't adjusted the experimental conditions well, can justifiably paddle, pretending that they are groping for the experimental conditions, and they can also find excuses for the failure of the experiment.

Now, I can only work honestly...

In addition to the affairs of the laboratory, the results of the communication between the departments and the Jiangwan Living Park have come out regarding the dormitory.

The park agreed to open a number of places this semester, so that the eight major science and engineering colleges, including the Department of Materials, will calculate the list of students who need to change the dormitory, and then arrange the dormitory change uniformly.

However, students only have one opportunity to apply uniformly in one semester, and after changing the dormitory, in principle, they will not be allowed to change the dormitory again within two years.

Xu Qiu reckoned that the park probably didn't want to let go at first, after all, changing dormitories is a rather troublesome thing for the park, and it's thankless.

Later, the park may have been forced to compromise under the pressure of the school’s top documents and major departments, but they also put forward their own requirements, that is, no second change of dormitory is allowed.

In the end, all the graduate students in the research group, except Duan Yun and Chen Wanqing, changed their dormitories from Handan to Jiangwan.

Duan Yun and Chen Wanqing basically don't show up in the laboratory very much now, so they don't bother to change dormitories.

The job of moving was similar to when Xu Qiu was promoted from undergraduate to graduate school. After the luggage was packed, the school would help with the transportation.

Now, Xu Qiu has activated the access card of the Jiangwan dormitory, returned the old key, received a new key, and lived in the new dormitory in Jiangwan.

The dormitory on the Jiangwan side was mainly designed for law school undergraduates when it was built before, and it didn't take into account that a large number of science and engineering graduate students would come in the future.

Therefore, the room structure is similar to Xu Qiu’s undergraduate dormitory: a standard room for four people, with an open space in the middle, four beds and tables on both sides, and a balcony for drying clothes and washing machines. The size of the room is larger than that of undergraduates. The bedroom is even bigger.

If four graduate students live in a four-person room, the dormitory conditions will be much worse than those on the Handan campus, and there is a high probability that students will not be willing.

However, if the dormitories are arranged according to the standards for postgraduates on the Handan campus, that is, two master students share one room, and doctoral students and postdoctoral students share one room, there will be insufficient dormitory resources.

In the end, the park adopted a compromise option, that is, three male master students share a dormitory, two male doctoral students share one dormitory, two female master students share one dormitory, and two female doctoral students share one dormitory.

However, there are only a small number of students who choose to move from Handan to Jiangwan this semester, because most research groups have not completed the relocation.

Therefore, the current situation is that Xu Qiu lives in a dormitory by himself.

After that, when a large number of students move over one after another, it is estimated that new roommates will be added.

As for Xu Qiu's former roommate Sun Yifan, he chose to stay in Handan this semester.

Xu Qiu guessed that he was going to be happy, so he moved away by himself, and Sun Yifan was equivalent to living in a single room by himself.

Because it is the second half of the semester, even if there are vacancies over there, they will usually be vacant, and there will be no newcomers to fill in.

In this way, Sun Yifan can live broadcast with peace of mind.

The students here are moving their dormitories, and Wei Xingsi's office has also been moved from Handancai 1218 to Jiangwan Xiancai 513.

The furniture in the office has not been replaced, and the original furniture, including the fish tank with only a few dead fish, has been moved here.

According to Wei Xingsi, it is because they are used to the furniture and have feelings for it.

Finally, there is the matter of course selection.

Xu Qiu this semester is the same as last semester, taking about 10 credits of courses, which are also arranged on Thursdays.

Taking 10 credits per semester, you can almost complete all the credits required by direct PhD students within two years.

This is mainly because Xu Qiu is preparing for his graduation ahead of schedule. He thinks that his various abilities in scientific research have reached or even surpassed the level of a normal doctorate.

If he could get his doctorate earlier, Xu Qiu would definitely not want to delay it for a few more years.

No matter what industry you are in, age is the biggest advantage.

For example, in the scientific research circle, if the threshold of 45 years old is reached, if you cannot be rated as Jieqing or Yangtze River, the way forward will basically be cut off.

The same is true within the system. If you can't reach what level at what age, your future promotion path will be cut off, and you can only endure retirement.

In essence, there are too many people, rolls, red seas, too many objects to choose from, those with high comprehensive scores go up, and those with mediocre scores go down...

Therefore, for most people, they have neither relationship nor ability. It may even be a big threshold to enter a university to obtain an establishment, a lecturer to an associate professor, and an associate professor to a full professor...

However, Xu Qiu felt that he still had to go to Wei Xingsi's side to find out.

Although when Wei Xingsi first joined the research group, Wei Xingsi said that he could graduate early, as long as he had to meet twice the requirements set by the school, but now, Xu Qiu has more than ten SCI articles written in one area and one, and he can graduate at least two years earlier, or even Graduated in three years.

But in case Wei Xingsi changes his mind and refuses to let him go, it will be a difficult problem.

Because whether it is domestic or international, the relationship between mentors and students in the scientific research circle is unequal at this stage, and the former has almost decisive control over the latter.

This will lead to a result, that is, postgraduate admission is equivalent to a big gamble, to hand over one's future destiny to a completely unknown person, and to hope that the other party's character is good enough.

This system is naturally unreasonable.

However, in the process of the rapid development of the scientific research circle of florists, the supervision also turned a blind eye to this phenomenon. The world is vast and the development is the largest.

But now, the situation has begun to change, the authority of tutors has gradually been reduced, and the supervision and control of scientific research funds has become more and more strict.

The reason behind this change can be considered to be a change in the relationship between supply and demand.

In the past, there was an extreme shortage of flower growers and scientific researchers. As long as the scientific researchers produced results, even if there were some minor problems that did not affect the overall situation, and even illegal behaviors such as cashing out of scientific research funds, they could be tolerated.

Now, the scientific research circle has become a red sea, and there is no shortage of low-end scientific research talents. If there are people with problems in history, the supervision may praise them for their merits. If they can continue to work hard now, the past can be forgotten;

But if you still commit crimes against the wind, then I'm sorry, not only the current account has to be settled, but the past may also be liquidated, and then someone else will take the place. Anyway, there is no shortage of people.

In fact, a certain payment company is in a similar situation at the present point.

In the beginning, they filled the gap in the domestic micropayment field and contributed to the development of the entire society. Therefore, some behaviors that borderline the ball can be tolerated, and the merit outweighs the demerit.

But when they grow stronger, they take the wrong path, do things they shouldn't do, and even establish universities to try to pass on this value, and they are sanctioned as a result.

Monday, March 7.

Although the school has officially started, the campus in Jiangwan Campus is not lively and relatively deserted.

Wei Xingsi occupied Jiang Wan Xiancai's conference room on the fourth floor and held a group meeting.

Now Teacher Wei can directly learn about the experimental progress of the organic and perovskite teams through Xu Qiu and Wu Feifei.

Therefore, his demand for the group meeting has been reduced a lot, so he changed the group meeting from the original Monday to every two weeks.

The perovskite team first reported,

In the past two weeks, Sun Wo has still made some progress. He achieved the efficiency of two-dimensional tin-based perovskite devices to 6% through the strategy of mixing lead and tin.

Although it is actually 75% lead and 25% tin, the main body is still lead, but at least it has tin, so you can rub a bright spot of tin.

Duan Yun and Chen Wanqing did not report. During this period, their graduation thesis was also distributed to other people in the research team to help with the final review, and then handed over to Wei Xingsi for revision. It has almost been revised.

In fact, Wei Xingsi didn't read their graduation thesis too seriously, mainly changing the format.

On the one hand, after nearly three years of high-pressure training, Duan Yun and Chen Wanqing's level of article writing is still relatively high, so he doesn't need to worry too much.

On the other hand, this thesis is a student's graduation thesis, and the requirements for review are much lower than those for publishing articles in the first and second areas of SCI.

Therefore, as long as the format is clear, even if you only translate your own work, there will be no problems, and there is no need to worry about plagiarism checks and blind review failures.

Generally, there will be blind review or those who fail the plausibility check, and they are basically doctoral students who have no scientific research results.

Of course, the lack of scientific research results is not necessarily their personal problem. It may be that the research direction of the group is not easy to publish articles.

At the level of Duan Yun and Chen Wanqing, although they are not top-notch in Wei Xingsi's group, outside, from the perspective of scientific research results, it is conservatively estimated that they can beat 70% of doctoral students.

Whether they can graduate or not, the review and defense of their graduation thesis are trivial matters. It simply depends on whether Wei Xingsi is willing to let them go.
