Chapter 310: Sure enough, hugging the thigh is right

"I have a scientific research support system novel ( to find the latest chapter!
After hanging up the phone, Mo Wenlin said to Lu Binghui: "Teacher Gong is looking for me."
"Didn't you ask me to join me?" Lu Binghui asked hurriedly.
"No." Mo Wenlin shook her head.
"It's estimated that you were chosen as an exchange student." Lu Binghui secretly breathed a sigh of relief.
After Lu Binghui’s previous master’s tutor had an accident, he changed his tutor to Gong Yuanjiang. Now that one year has passed, he finally got acquainted with Gong Yuanjiang. In fact, he didn’t want to go to the magic city. There was a feeling that the tutor had another surprise. In addition, he also studied at Kainan University, so he still has feelings for Kainan University.
However, he belongs to the type of beloved baby and has been afraid of teachers since he was a child. When Gong Yuanjiang talked to him and asked him if he intended to go to the Magic University for communication, he subconsciously agreed, and then he did not have the courage to be like Teacher Gong. Explain the situation.
You know, although Gong Yuanjiang treats Wei Xingsi and Xu Qiu more easily, he is also stricter in the group. Otherwise, it is impossible to produce so many academic achievements. He can become a "Yangtze River" scholar, except for those whose luck is against the sky. Basically, they are ruthless people, ruthless to themselves, and ruthless to their own students.
In such an involved society, no matter what field you want to stand at the top, in addition to relying on illusory luck, hard work is basically indispensable.
Even the masters of Chenggong have to work hard to make a lot of income.
Mo Wenlin looked at Lu Binghui thoughtfully, and said, "Then I will go."
Her situation is different from that of Lu Binghui. It hasn’t been long since she came to Gong Yuanjiang’s research group. A new environment will have little impact on her. Moreover, her undergraduate and master’s Dongfa University is also in Magic City, and her English level is not very good. Outstandingly, I felt that it was a little difficult to enter the Department of Chemistry at Mordu University, so I went to Kainan University to find the next best thing.
When Gong Yuanjiang talked to her, she did not directly agree. Instead, she considered for three days. During these three days, she read the entire website of Wei Xingsi’s research group, including all the latest articles, and finally found After some analysis of the existence of Xu Qiu's thigh, she believed that if she could hold her thigh, the development would obviously be better than it is now, so she agreed to Gong Yuanjiang's request.
At that time, she originally regarded Lu Binghui as a imaginary enemy, thinking it was a competitor, but now it seems that the other party does not have the willingness to go to the Wei Xingsi group to communicate, and is very indifferent to Wei Xingsi and Xu Qiu.
Mo Wenlin wanted to ask: "Then why did you agree with Teacher Gong in the first place, did you force a ‘differential election’?" Of course, she just thought about it in her heart and would definitely not ask.
Gong Yuanjiang's office.
"Mo Wenlin, then you will go to the Wei Xingsi teacher group for a two-year exchange." Gong Yuanjiang said straight to the point.
"Okay." Mo Wenlin quickly responded.
"When can you come to the magic city?" Wei Xingsi asked.
"Hmm..." Mo Wenlin hesitated and said, "You can do it anytime, I don't have much luggage."
"That's right," Gong Yuanjiang interjected, "She hasn't got her master's degree yet. She rents an apartment here. You can get the accommodation, right? The rent in Magic City is not cheap."
"These are all trivial things, I will find a way." Wei Xingsi tentatively said: "If possible, will we return to the magic capital after the meeting next Monday?"
"No problem." Mo Wenlin nodded.
"The communication procedures can only be done after the beginning of school," Gong Yuanjiang reminded: "Now she is still a black house, and she must be careful about doing experiments, otherwise there will be problems and more trouble."
"I know this naturally." Wei Xingsi paused and said, "Since the candidate has been determined, Yuan Jiang, I'll give you a message. Have you seen the AEM that our group recently published?"
"Oh...that article, there are impressions, there are impressions, Mo Wenlin, you can talk about it," Gong Yuanjiang said.
Mo Wenlin said without hesitation: "The latest AEM by Mr. Wei’s research group is to report an ADA-type non-fullerene acceptor material called IDT-ICIN, combined with FTAZ donor material, the photoelectric conversion efficiency of the device can be Up to 6%..."
Xu Qiu murmured secretly, Mo Wenlin must have done her homework in advance, because most people only remember a general idea about this kind of literature that is not her own work.
"ICIN, this is a new structure," Gong Yuanjiang wondered: "Is there anything special? Xu Zhenghong's IDTBR has achieved 10%. I heard that it will break through again."
"Really? Did they vote for the article? I don't know about it yet." Wei Xingsi was taken aback, and Xu Qiu was also taken aback. Since it can be called a breakthrough, it is definitely not a small mess like an increase of 0.1% or 0.2%. , The high probability is an increase of 1% or even higher.
"It's still Liang Haoxian's work. I heard what they said yesterday," Gong Yuanjiang explained: "It seems that the side chain has been changed. The new materials are called IDTBR-EH and IDTBR-O. The efficiency is just over 11%. You voted for EES. Just know it for yourself, don't spread it outside."
"Yes, it must be kept secret." Wei Xingsi assured.
"By the way, you just mentioned the structure of your ICIN..." Gong Yuanjiang turned the topic back.
"Oh, our system has also made a breakthrough, and the efficiency is now more than 6%." Wei Xingsi said calmly. Xu Zhenghong's new IDTBR system, if only the side chain is changed, will not have a big impact on the ITIC series in his group. .
"8%?" Gong Yuanjiang observed Wei Xingsi's expression and continued: "9%? More than 10%?"
"Right," Wei Xingsi nodded, "and it's only a preliminary result, there is room for further improvement."
Gong Yuanjiang looked at Xu Qiu next to Wei Xingsi and said, "Is this classmate Xu Qiu your job?"
"That's right, the ICIN unit is my preliminary idea. Our group Chen Wanqing was responsible for synthesizing the system. I designed and synthesized the system that recently exceeded 10% efficiency." Xu Qiu said simply, no The published work was not too detailed.
Mo Wenlin looked surprised. It seems that it is time to join Wei Xingsi’s research group. Xu Qiu and the others have just developed a new type of molecular structure. Go in and give her a small idea. Sending a second district article is very good. Stable, even a section of the article is not hopeless. Sure enough, holding the thigh is right. Lu Binghui still doesn't know what opportunity he missed.
"Yes, then I have to study the structure of your ICIN." Gong Yuanjiang's expression became serious. This news is also very important to him.
For the field of organic photovoltaics, every system that can achieve double-digit efficiency, that is, more than 10%, is worthy of attention, because there are not many such systems.
Now two types of ADA materials have suddenly appeared in the non-fullerene field, and the efficiency has reached more than 10%. In addition, Wei Xingsi's research team has also refreshed the value of the PDI system to about 9.5%. It is estimated that it will be a matter of time before 10%.
There are indications that the non-fullerene field is brewing up.
Each research group has its own subdivisions. For example, although the Gong Yuanjiang group has been involved in various systems, it is better at the development of small molecule donor materials. This is a relatively niche field with few researchers. At present, the best one is Gong Yuanjiang. In recent years, he feels that some research has not moved. He can't break through the efficiency no matter how he does it, and he can't see the way forward.
Now Gong Yuanjiang has a choice, which is to change the focus of his research group and switch to a non-fullerene system.
As the saying goes, a small boat makes a U-turn. The large research group has a series of advantages, but naturally there are also disadvantages. For example, the Gong Yuanjiang group, once the main research direction is changed, many of the advantages brought by the previous accumulation will no longer exist, and the small molecule donor materials are harvested. Experience cannot be simultaneously transplanted to non-fullerene recipients.
Gong Yuanjiang thought carefully for a while and made a decision: "The main research direction in our group has to change. Thank you Xingsi brother for telling me this news."
"Don't be polite between us." Wei Xingsi smiled and waved his hand. He told Gong Yuanjiang that the main reason for the news was the exchange student plan.
Mo Wenlin came to his group, a bit of a "spy". If she was not allowed to contact the core experiment of the research group, why did she get people over? But if she was exposed to the core experiment, she would most likely inform Gong Yuanjiang there. , After all, the articles published by Mo Wenlin's work must bring both sides of the communication.
Wei Xing thought and thought, it would be better to take the initiative to tell the news, and to get a favor. Although he and Gong Yuanjiang were very good friends before, they only had a good relationship with each other. There was no exchange and binding of interests. They can be regarded as friends, but now they are different. The two can become hard-core allies, form a cooperative alliance, and build the same similar system. The experimental plan is to communicate with each other, at least not to crash.
"Brother Xingsi, let me tell you something too," Gong Yuanjiang said suddenly:

Zang Chaojun and Lu Changjun’s research found that a fixed-area battery device in a traditional beautiful country, when light irradiates the entire effective layer area, there will be a lateral photocurrent, which leads to a certain degree of short-circuit current density measurement of the device. error.
Therefore, they promote the preparation of large-size battery devices, and then use a fixed-size mask to calibrate the effective area. This has many advantages. For example, by preparing a device, in theory, you can get an arrayless battery device..."
"I've heard of this..." Wei Xingsi pondered for a while, and said, "Are they planning to advance in the direction of application?"
"Yes, if you want to apply in the field of organic photovoltaics in the future, you must take this step. You can't always make battery devices as large as 0.04 or 0.09 square centimeters." Gong Yuanjiang bends his and makes gestures of several areas: " I think it’s the starting point for a 1 square centimeter device."
"The application of organic photovoltaics, can we see that day?" Wei Xingsi seemed a little pessimistic.
"We always have to work hard in this direction, right?" Gong Yuanjiang asked firmly.
"Well, you are right." Wei Xingsi smiled and nodded.
The ultimate goal of scientific research is still application, but in fact, most of the directions are dead ends, and very few areas that can be applied are the results of many years of grinding.
Just like lithium batteries, lithium metal batteries were first proposed and studied by Gilbert N.Lewis in 1912. They only began to be commercialized in the 1970s. After the 1990s, they were replaced by lithium ion batteries due to safety issues. Now lithium ion batteries are widely used in mobile phones, Computers and other electronic products.
Researchers at the level of Wei Xingsi and Gong Yuanjiang naturally know that the "application of organic photovoltaics" is likely to be a lifetime series, and may develop in 50 or 100 years. They may have already left by then and turned into a pile of things. There are names on the monuments composed of historical documents, but at least now I have chosen this scientific research path, and I have chosen this field, and I have to shoulder the responsibility and cannot shrink back.
Xu Qiu doesn’t know what the future of organic photovoltaics will look like, but he is still relatively optimistic. After all, he has a system in hand. If more functions can be unlocked in the future, he might not have the opportunity to greatly promote the organic photovoltaics field. The process of industrialization.
After the exchange between the two teachers, Wei Xingsi confessed to Xu Qiu: "Come to my room at eight o'clock in the evening and sort out the report for tomorrow and Sunday." He was going to visit several other teachers in the afternoon, and he didn't plan to take Xu Qiu.
Xu Qiu was also very happy to have a leisurely time, just to take a stroll around Tianjin, but there was no one for lunch and dinner, so he had to solve it by himself.
When parting, Mo Wenlin added Xu Qiu's WeChat, Xu Qiu smoothly pulled her into the group chat of the research group, and introduced her to other friends.
Everyone expressed their welcome, Tian Qing teased: "Xu Qiu went on a business trip, so he abducted another girl back."
Han Jiaying also posted a "hatchet" expression, and Xu Qiu hurriedly explained to her that although she knew that school girls weren't the kind of petty people, the girls wanted to coax, and the attitude should be done~www. EbookFREE.me~ In the afternoon, Xu Qiu went out and wandered at will. Mo Wenlin even sent him a message saying "I want to be a tour guide", but he refused. How can I live in the magic city for seven years and then just came to Tianjin? Within a few days of the city, she worked as a tour guide, and Mo Wenlin was not from Jincheng either.
Xu Qiu didn't go too far, so he visited two adjacent universities, Kainan University and Jincheng University, both of which are 985 universities.
Then, he found that the universities are similar. The two universities are not much different from the Magic University. It feels more suitable for children from middle and high schools to take a look and have a long experience.
