Chapter 163 How to Assess the Level of Scientific Research

The welcome party is over, and the day returns to the normal rhythm.

Xu Qiu continued to take Han Jiaying to do experiments.

In fact, he also thought about whether he should simply leave the finishing work to his seniors or juniors, and then go to new fields by himself, such as studying "non-fullerene derivative receptors".

In the end he still didn't make such a decision for a number of reasons:

First of all, his current research on polymer donors is relatively mature, and there are many similar works that can be used for reference.

If you encounter a bottleneck in the research process, you may be able to get inspiration from other people's work by looking through the literature.

However, there are few related studies on non-fullerene derivative acceptors, and from the perspective of the photoelectric conversion efficiency of the device, there are not many successful cases.

By borrowing from the work of others, you are likely to lead yourself into the ditch.

Moreover, many relevant documents are five or six years ago.

Because Mr. Wei would only give them recent published literature in the field, Xu Qiu needed to independently search and study the literature, which would take a long time.

Recently, the focus of his literature reading is on the field of non-fullerenes, but it will take some time to accumulate.

Secondly, from the perspective of Mr. Wei.

He has just returned to China to set up a research group, and he needs a lot of articles in the early stage, so he can't always use his research results in the United States as a facade.

Teacher Wei is very eager for articles. Chen Wanqing used "ternary blends" and "ternary conjugated copolymers" to write articles.

In his heart, he actually looked down on such a result, but he finally compromised.

In contrast to Xu Qiu's system, even if Chen Wanqing and Han Jiaying were assigned to do the experiment, the writing of the article would still fall on him.

The senior sister's ability to write articles is a little anxious, and the junior sister has not written an article yet.

Moreover, it is not easy to assign one work in this way, and it is impossible to get a total of one for each article.

Finally, from the perspective of Xu Qiu's personal development.

He also needs articles, because the articles are not only related to his evaluation and awards during his graduate school, but also related to his future promotion path.

After all, the overall atmosphere of the domestic scientific research circle still values the quantity and quality of articles.

This method of evaluating the ability of scientific research workers is relatively simple and crude, and there are certain problems. Considering the differences in different fields, it is actually not very objective to evaluate their scientific research level.

But just like the college entrance examination, there are many problems, but at this stage, there is no other effective means that can replace it.

In essence, each person's ability level cannot be quantified and quantified like in the game, and the evaluators are also mortals with naked eyes, so they can't tell what a person's ability is at a glance.

Like the college entrance examination, you can only do one size fits all. First, you can roughly divide it into categories based on your grades.

The scientific research circle is similar. Everyone has a different research field. They are both doing scientific research, and the differences between different fields are very large.

It is not necessary to judge the level of the article, but it must be reviewed by experts in the same field.

However, sending three or five experts in the same industry for each assessment is easier said than done.

Because there are usually only one or two experts in the same field in a school, and three or five experts need to be collected, and most of them have to go to other schools or other provinces to transfer people, which is too time-consuming.

However, the division of SCI journals and the evaluation of the number and quality of articles form a quantitative standard, which allows laymen to roughly distinguish a person's research level.

...

Xu Qiu's experimental data is being replenished steadily, and one or two data can be obtained almost every day.

On Friday afternoon, Han Jiaying was spinning in the glove box.

She used tweezers to pick up the substrate that had just been painted, and said to Xu Qiu:

"Senior brother, I haven't painted it well. This kind of hot spin coating is really too difficult to operate."

"It's normal, let's redo one piece," Xu Qiu said calmly:

"Even if I operate it, it's not 100% successful, and there is about a 10% chance of failure."

Indeed, the operation of true hot spin coating should be the most difficult one in device preparation.

Not only requires very fast hand speed, but also ensures that the pipette tip does not touch anything in the glove box during operation, such as solution bottles without caps.

Otherwise, the failure of the experiment is trivial, and it is enough to redo one piece. If the effective layer solution contaminates equipment such as balances, then the problem will be serious.

"Brother, why don't we find Teacher Wei..." Han Jiaying said cautiously.

Xu Qiu probably understood what she wanted to say.

He had considered buying a microwave synthesizer for synthesis and a heatable coater for thermal spin coating before.

It seems that there is no need to buy a microwave synthesizer for the time being, but a heatable glue homogenizer is still necessary.

Because of true hot spin coating, in addition to high requirements on experimental techniques, there are still other flaws, such as the inability to ensure the consistency of each spin coating condition.

For 20 microliters of solution heated to about 100 degrees Celsius, the temperature loss rate is very fast in the air at room temperature.

In one second, the temperature may change by a few degrees Celsius.

Therefore, the repeatability of the data is much worse than that of the traditional room temperature spraying method.

Moreover, every spin-coated substrate has a large circle in the center, which does not look very beautiful.

"I'll find an opportunity to talk to Mr. Wei, and apply to buy a glue dispenser with an integrated heating system." Xu Qiu said.

"Really? That's great." Han Jiaying said happily.

"Go ahead with the experiment, I'll check it out first," Xu Qiu said.

"Yeah." Han Jiaying nodded.

...

Xu Qiu returned to the desk and sat down.

Ask Teacher Wei to apply for funds to buy equipment, or just go over with a mouth and say, "Teacher, I want to buy XXX".

Well, I feel like I'm going to be scolded back.

It's better to conduct research first and show him the preliminary results.

But how to find it?

It is definitely not reliable to find TB for such tens of thousands of instruments.

Search online first.

Enter the keyword, "heating glue homogenizer", there is only one company, and other search results are all ordinary glue homogenizers.

It seems that there are not many doing this in China.

When Xu Qiu opened the company's website, the picture looked like an ordinary glue dispenser, but the text description showed that it integrated a heating mode. Then he looked at the price.

1111111 yuan.

This doesn't look very reliable, it's obviously not like doing business with sincerity.

There are two contact methods under the website, a landline phone number and a mobile phone number.

Xu Qiu called the landline first.

However, no one answered.

Tried again, still no answer.

Now Friday afternoon, weekday, don't they go to work?

Xu Qiu tried to dial the phone number.

188...

"Hello, the number you dialed is an empty number..."

Well, the company went out of business.

It's really unreliable.
