I Have a Research Support System

It seems that online search, this road is not going to work.

In fact, Xu Qiu was originally apprehensive about this method.

Because it is difficult to know the basics of the manufacturers, they may go bankrupt and run away one day. Most domestic companies have a life span of only a few years.

It’s okay to buy an oil bath for a few hundred yuan, but if you buy an instrument worth tens of thousands of yuan online, it will be very troublesome if you encounter after-sales problems later.

It seems that we can only find offline channels.

But how to find offline channels?

Xu Qiu tentatively asked Chen Wanqing beside him:

Senior sister, do you have a channel to buy a heating glue machine?

No, there don't seem to be many manufacturers doing this in China now, Chen Wanqing shook her head and said:

Let me send a message to the sales of several optoelectronic material companies to ask, but don't hold out too much hope.

That's the only way to go. Xu Qiu said.

This is difficult. If you can’t buy a ready-made instrument, is it possible to learn from Duan Yun and DIY an instrument yourself?

It is not impossible, but considering the time cost, it is not a good choice.

Moreover, someone in the literature has used this kind of glue homogenizer with heating function, which shows that this kind of instrument must exist.

It's just that they didn't give the model of the instrument in the experimental part.

I don't know if they forgot to write it, or for some other reason.

...

When Xu Qiu was struggling, the sound of Teacher Wei's leather shoes suddenly came from the corridor.

After a few seconds, Wei Xingsi appeared at the door of 216.

From the looks of it, he should have just come back from the outside and passed by the laboratory for a routine inspection.

As soon as he entered the door, he saw Xu Qiu staring at the computer screen in a daze, and asked:

What are you busy with?

Since Teacher Wei asked about it, Xu Qiu simply told the whole story:

For my P4T derivative system, in order to obtain high photoelectric performance, a special spin coating method, thermal spin coating, is required.

The basic principle is to maintain a high temperature environment during the spin coating process, such as 100 degrees Celsius.

However, our current ordinary glue coater cannot realize this process, and can only approximate the simulation, heating the solution and the substrate to the temperature we need, and then spin coating quickly.

However, the operation of this method is very difficult and rough, and the actual conditions of each spin coating will have subtle differences.

I was thinking, if I buy a homogenizer integrated with constant temperature heating, it will be much more convenient when doing related experiments, and the data stability will also be improved.

Then buy it, what's the approximate price? Teacher Wei said.

It's estimated to cost tens of thousands of yuan, but I searched online, but I couldn't find any relevant manufacturers. Xu Qiu looked in Chen Wanqing's direction, and continued:

I asked Senior Sister Chen Wanqing to find some optoelectronic material companies and ask them. They are the companies that we usually buy monomers and polymers. They...

After speaking, he winked at the senior sister.

Chen Wanqing understood, and said:

I asked five companies, and three of them responded that there was no relevant channel, and the other two haven't replied to me, probably...

Teacher Wei interrupted:

Okay, I see, I'll take care of it, Xu Qiu, come with me.

...

Room 218.

After Wei Xingsi entered the door, he took out two bottles of Nongfu Sanquan from under the tea table, unscrewed the caps and poured them into the kettle, saying:

Did you just mention the heated gluing machine, the one that converted the suction table of the ordinary gluing machine into a heating table?

That's right. Xu Qiu replied:

Or close the glue homogenizer, do a good job of heat insulation, and then heat the inside to keep the temperature constant.

Well, there are both of the two you mentioned. Relatively speaking, the former is more commonly used, but I have never used either of them, I just heard of them. Wei Xingsi thought for a few seconds and continued:

Let me call and ask.

After speaking, he took out his mobile phone and flipped up and down in the address book.

After staying in front of a name for a while, he shook his head slightly, and continued to scroll down.

In the end, he stopped at Gong Yuanjiang's name and pressed the dial button.

He didn't turn on the speakerphone, and the two were far away, so Xu Qiu could only hear Teacher Wei's voice.

Hey, Yuan Jiang, it's me, Wei Xingsi.

How about it, is it going well recently?

I just came back to China and I'm very busy. I'll definitely go there when I'm free.

Yes, everything is difficult at the beginning.

By the way, I have a student who has encountered some small problems in the experiment. He wants to buy a glue spreader with heating function. Do you have any channels over there? We want to get one.

Yes, that would be great.

That's right, the one with its own heating table.

Okay, okay, wait for you to send me the contact information, I will let my students contact your students, thank you so much.

Okay, I'll keep in touch when I'm free, bye.

The phone hangs up.

The water that was boiled just now has boiled. Wei Xingsi opened a pack of tea leaves, first rinsed the teapot with boiling water, then put in the tea leaves, poured in boiling water, poured out the first brewing water, and started the second brewing.

It's done, Wei Xingsi said with a smile:

Gong Yuanjiang is a friend I met in the early years, and he has been doing organic work in China for more than ten years.

Now he is a big name in the field of organic photovoltaics, and you should have read a lot of his articles.

Xu Qiu nodded. The name Gong Yuanjiang is no stranger to Xu Qiu. He is one of the leaders in the field of organic photovoltaics in China, and you can often see his articles as the corresponding author in top journals such as AM.

He said that there is no domestic manufacturer of this kind of heating and dispensing machine, and they have to import it from abroad.

Their group is relatively large, and there will be a few extra sets of this kind of equipment, so I'lend' the spare one to us, and wait for you...

At this time, Teacher Wei's cell phone lighted up, and it was a text message.

He glanced and continued:

This is the phone number of the student in Gong Yuanjiang's group. I'll send it to you. You can contact him and tell him our address. We need to mail it over. We will pay for the courier fee.

Have you received the text message?

received.

Is there anything else?

there is none left.

Okay, then go get busy, and contact me in time if you have anything to do.

...

Leaving Teacher Wei's office, Xu Qiu couldn't help but sigh with emotion. After working for a long time, Teacher Wei solved it with a phone call.

If I had known earlier, I might as well have opened my mouth and went directly to him.

Xu Qiu also once again realized the importance of the team.

Teacher Wei has been in the field of scientific research for more than 20 years. Although he mainly develops abroad, he still has certain resources and contacts in China, and he will make more use of them in the future.

After all, as the leader of the entire scientific research team, Xu Qiu has made achievements, and for him, it is also a win-win situation.

As for the PY of an instrument between Gong Yuanjiang and Mr. Wei, what is the nature of this and what process should be followed.

Xu Qiu didn't know either, anyway, he just did his own experiments well.
