I Have a Research Support System

Another AM article was published by a foreign research group.

What they did was the traditional PCE10:PCBM system. A small amount of polymer acceptor N2200 was added to this binary benchmark system as a "morphological lock" to construct a ternary system and finally obtain a more stable organic photovoltaic system. device.

They claim: "N2200 locks the morphology of the blend film like glue. This article provides a new way to solve the problem of poor device stability that has plagued the field of organic photovoltaics for many years."

Xu Qiu found out that when foreigners boast about their work, they will not be ambiguous, and they will also "lock their appearance"...

Overall, it's a decent job.

Anyway, Xu Qiu got nothing after reading it, of course, because the other party's work is not very relevant to his research field.

There is also N2200 material in the group, but he has never used it, but Duan Yun has used some.

At the same time, Xu Qiu found that his mentality was constantly changing as he spent more time in scientific research.

When I first entered the scientific research circle, I often felt: "Wow, this idea is so powerful... Ah, this job is strong."

Now he writes a lot of articles and publishes a lot. I feel that the work of many colleagues is just like that. If you want to criticize yourself, you can always find problems in other people's work.

In addition, Xu Qiu didn't have much impression of the names of the corresponding authors of this article before, and he didn't know whether they were big shots or unknown people.

In the field of organic photovoltaics, Xu Qiu can basically name the big names among domestic and Chinese researchers, but not necessarily foreigners.

On the one hand, it is because the names of foreigners are relatively difficult to remember and pronounce. Except for some simple names, such as Mark, most of the names of foreigners.

For example, Christoph****rabec and Ullrich Scherf appearing in this article, in Xu Qiu's view, are just a string of gibberish.

However, if you are a domestic or Chinese researcher, your name is in Chinese pinyin, and you can read it easily. Even if you don’t know how to write the corresponding Chinese name, you still know how to pronounce it.

On the other hand, it may also be related to the relatively large number of articles published by domestic researchers in the field of organic photovoltaics.

If there are many articles published, you can often see their names in the process of reading the literature, which will naturally leave a deep impression on Xu Qiu.

As for the reasons for this situation, it is also easy to understand - in the current domestic scientific research circle, the mainstream means of judging the performance of a scientific researcher still depends on the quantity and quality of his SCI articles.

Under the coercion of such a big environment, individuals want to go against the trend. For example, I only publish high-quality articles, for example, I have to carefully polish every job, which is very difficult and thankless.

A researcher who chooses "Three years of sharpening a sword, and the sword will kill people (Bifa CNS)", there is a high probability that the sword will be broken in the middle of sharpening the sword.

If it is a master-level researcher who has already achieved success and fame, the sword will be broken if it is broken, and there is still a chance to start over.

For Qingjiao scholars, especially those who have signed a promotion-or-leave agreement, this break will ruin their entire scientific research career.

Therefore, there are also many people who will choose "the article is cool for a while, and the article is always cool", as long as the quantity of the articles is not the quality of the articles. After all, it is easy to obtain quantity, but it is difficult to obtain quality.

They regard scientific research only as a kind of job for earning a living, a business. Although unlimited water articles will cause a meaningless waste of scientific research funds, it is also understandable.

There are also some researchers who choose "I want both quantity and quality". They do not reject low-quality articles, but they also strive to pursue high-quality work.

The situation in Wei Xingsi's group is closest to this one, and this may be the most "correct" choice for the individual.

In addition, I have to say that although the current mainstream idea in the academic circle is to evaluate a person's scientific research level according to SCI articles, in fact, there have been some "non-mainstream" voices in the scientific research circle in recent years.

They said: "We need to establish a more reasonable evaluation method of scientific research level, and prevent researchers from being kidnapped by SCI papers."

Moreover, according to the current trend, this kind of voice appears more and more often, and it is getting louder and louder.

Many high-ranking officials of the Ministry of Education, or some "Jieqing", "Yangtze River", and academicians made similar proposals.

There is nothing eternal in the world, and maybe the judging system in the academic circle will really change in the future.

But Xu Qiu really couldn't imagine what form the new system would take.

Internal selection by schools and departments?

Obviously inappropriate, because there will not be too many researchers in the same university with repeated research fields, which means that most of the teachers in the department have different research fields from each other, and it is difficult for them to objectively comment on other research fields. How well people work.

For example, for people in the field of organic photovoltaics, they can easily understand how significant it is that the IDIC-4F material developed by Xu Qiu breaks the device efficiency to 13%, and at the same time can manufacture large-sized, thick-film devices. matter.

But if you put it outside, if you want people in other fields to understand this, it will take a lot of time to give examples.

Then regularly organize colleagues to meet together, hold a "Huashan Discussion of Swords", and have an ideological collision together?

It sounds reasonable, as colleagues gather together, it is easier to compete and understand what each other is doing.

But it is too troublesome to do so. Everyone is a researcher of "machines" and has their own affairs to be busy.

For some unpopular fields with few researchers, it’s okay, and it’s not difficult to organize. For some hot fields, there are fifty or sixty or hundreds of people. For a meeting of this scale, everyone should talk, and no one should be held. Week, half a month.

Such meetings are held twice a year, and there is nothing to do in a month.

Although he couldn't imagine how the new system would appear, Xu Qiu could probably figure out why the public opinion had changed now.

In short, the previous approach was outdated.

Any policy has pros and cons, and is time-sensitive.

Some concepts or methods are very problematic at present, but at a certain historical moment in the past, they may be life-saving straws and a shot in the arm.

For example, real estate, which has been raging about, now seems to be a very serious problem. The development of real estate is very abnormal. High housing prices have also caused a series of social problems, including the decline in the desire to have children, which in turn leads to the aging of the population and so on.

But if we go back 20 years, if the real estate industry is not booming at that time, the domestic economic development speed may not be so fast, and it will not allow flower growers to complete the 30-year journey of developed countries in only 20 years. , 50 years or even 100 years.

Twenty years ago, when the common people had money, what would they choose to do? consumption?

Consumption is impossible. There is almost only one place for money to go, and that is the bank, where it is all saved.

And the money of ordinary people is kept in the bank, and if they don't spend it, no one will buy the goods produced by the factory;

If no one buys the product, the factory owner will lose money and run away with his sister-in-law;

If the sister-in-law ran away, the wages of the workers would not be paid;

If the wages of the workers cannot be paid, the workers have no money to consume, and they still save money to live on.

Vicious circle...

In other words, the essence of the problem is the lack of liquidity of the currency.

A large part of the reason why the country chose real estate at that time was that real estate was the means by which money and commodities could flow most at that time.

The currency consumed by itself is one aspect, and related businesses such as decoration will also drive the flow of related industrial commodities.

In fact, there was originally a stock market, but at that time the domestic stock market had serious problems and was unreliable.

Although "rejuvenating the country with real estate" is a joke, but to a certain extent, it is indeed true.

It's just that there has never been a free lunch in the world. If you enjoy the benefits of "real estate rejuvenation", you have to pay the corresponding price.

Accompanying it is the problem of advanced consumption, or debt.

It is said that 2% of the world's people now hold 118% of the world's property.

This value may be false, but more than 100% is certain.

So how did the extra 18% come from?

It is debt, and the remaining 98% of people spend all their future property in advance now.

A simple math problem, Xiao Ming spent all 300W to pay the down payment, and bought a 1000W house in Shanghai with a loan. The loan is 30 years, calculated according to the interest rate of 5%, equal repayment, and the total interest is 650W. May I ask him to buy a house? How much is your personal assets?

The answer is negative 650W. It seems that Xiao Ming is sitting on a house worth tens of millions, but his personal net assets are actually negative, that is, he has advanced the time value of the future and needs to work for 30 years to repay it.

Some people may say that housing prices will rise, and indeed they will, especially in the first-tier cities, and it has been rising for 20 consecutive years in history, but it cannot continue to rise without limit.

Considering interest rate, depreciation, real estate tax, transaction tax and other issues, real estate needs to appreciate by 10% every year to make a profit, and the growth rate of GDP of flower growers does not exceed 10% now.

The rate of real estate appreciation can "temporarily" exceed the rate of GDP growth, but how can it be possible to "always" maintain a rate of growth that exceeds GDP?

After all, the house itself cannot create value, it is just a means for the country to stimulate the economy.

Although the real estate is guaranteed by physical objects, it is not considered a Ponzi scheme.

But it is still similar to the Ponzi scheme. When the bubble expands to a certain extent, someone always has to take the last stick.

This is also the reason why the state has issued repeated orders recently that "housing should be lived in, not speculated", because real estate has completed its historical mission.

Returning to scientific research, the situation is similar. "Discussing heroes with SCI articles" seems to have completed its historical mission.

Around 2000, when the country was just beginning to promote scientific research and construction, it was very effective to use SCI articles as incentives that were tangible and relatively easy to quantify.

Moreover, at that time, even pure water articles in SCI journals could improve the voice of florists in international journals, so it would be good to increase the volume first.

Now, the quantity has been done, and the number of articles published by florists every year has become second only to the beautiful country in the world.

At this time, it is time to start thinking about qualitative issues.

PS: Ask for a monthly pass.
