Chapter 485: Wu Shengnan's chance to stay in school

In the evening, everyone in the research group went out for a dinner, and the place was chosen in a restaurant called "Guilaida".
　　 The shop’s signature is the charcoal-fired copper pot bullfrog. The research team was divided into two tables with more than a dozen people. They ordered four large pots of double-layer copper pot bullfrogs.
　　 On the way to dinner, Xu Qiu asked Tian Qing who was sitting at the same table: "We are going to a beautiful country for a meeting in April, and now we have to prepare the luggage, what advice does Senior Sister Tian Qing have?"
　　 Tian Qing stopped the action of picking up vegetables, thought for a while, and replied: "First of all, I suggest you bring some more domestic fast food products, because you may not be used to the food in the beautiful country."
"However, it is best to check the customs regulations of the beautiful country online, because not everything can be brought in. I remember that most meat products except fish are not allowed." Tian Qing paused and continued. Said:
"Of course, this is so strict when you go through the customs. If it's just for boarding, most food can be carried, but the premise is to finish eating on the plane, or leave things on the plane when you leave the plane. For example, I took two boxes of Zhou Gray Duck before going to Beautiful Country, and I ate it on the plane..."
　　 "Sister Tian Qing, can we talk about the key points, do you have any specific recommendations?" Xu Qiu asked.
　　 "Specific recommendation..." Tian Qing said without hesitation: "Instant noodles, the three of you can bring ten packs or fifteen packs of instant noodles. It can serve three to five meals, and eight-treasure porridge is also a good choice."
　　 "Instant noodles...Eight-treasure porridge?" Xu Qiu asked in a daze, "Isn't the supermarket in Meili Country selling these things?"
　　 Tian Qing said, "Yeah," nodded and said, "There are very few supermarkets in the beautiful country that sell instant noodles and eight-treasure porridge, because their citizens don't like to eat these things."
　　 "Although there are Chinese supermarkets over there, or the Asian merchandise area of ​​some large supermarkets, and Chinese settlements like Chinatown, they will sell these things, but it is difficult to tell if there will be sales near the MRS venue where you are located."
"If there is no sale near the venue, it will be more troublesome. You have to go to other business districts. Because the public transportation in the beautiful country is underdeveloped, so if you want to go to other business districts, you usually have to take a taxi. If you take a taxi, the cost will be very high. It’s worth tens of dollars at every turn, so it’s better to bring it domestically to save worry and effort."
When talking about travel experiences, Tian Qing became more excited and added:
By the way, when shopping for food, you should pay attention to meat products such as sausages that are not allowed to enter the country. There is a high probability that braised eggs are not acceptable. There is also instant noodles. It’s best not to choose Tang Shuaibo Braised Beef Noodles, you can choose Shin Ramen noodles..."
　　 Xu Qiu spit out: "If you don't buy Tang Shuaibo's braised beef noodles, you are afraid that there will be beef in it..."
"Yes," Tian Qing nodded: "If any meat ingredients are found in the food, they will be confiscated. The sausage is the same. Although most of the domestic ham sausage is starch, there will always be Some meat can’t be brought.

　　 At this time, Wu Feifei interrupted: "If we are afraid that we can't get used to it, we can also eat fast food such as Kaifeng dishes."
"It's okay, but..." Tian Qing paused, and changed the conversation: "In fact, there are not many Kaifeng dishes in the beautiful country, and the taste is average. I had it last time, and the fried ones were not delicious. It’s huge oil and salty. Of course, even if there are no Kaifeng dishes around the MRS venue, there are likely to be many other similar fried chicken burger restaurants, but eating fried chicken burgers every day is definitely not suitable."
　　 "That's true," Wu Feifei took it seriously, and then asked, "Apart from food, is there anything else that needs to be prepared?"
Tian Qing thought for a moment, and said: "If you go to a beautiful country, you have to take a long flight. It is best to bring a U-shaped pillow and a pair of slippers. Sitting for a long time will cause swelling of your feet, so you can Take off your shoes, it will be more comfortable, of course, provided that it will not affect other passengers."
"Other aspects..." Tian Qing continued: "You have bought the voltage conversion plug before. For the Internet, Mr. Wei rented WIFI for you. The rest is to bring a change of clothes, laptop, Necessary supplies such as mobile phones, credit cards, passports, banknotes, etc."
Finally, Tian Qing smiled:
Don’t imagine how difficult it is to go abroad. It’s easy to have English language advantages. As long as you don’t go out at night and don’t go to slums, it’s actually the same as in China. It’s not as dangerous as stated on the Internet, bullets fly over the head every day..."
　　‘It’s easy to go abroad? Xu Qiu said inwardly: "If I hadn't personally applied for a visa before, I would really believe in your evil."
try{mad1('gad2');}catch(ex){}　　…
　　 Time flies quickly, and in a blink of an eye it was March 31, the day before Xu Qiu and the others went to the beautiful country to attend the meeting.
　　 This morning, Wei Xingsi organized a simple group meeting in the conference room on the fourth floor of Jiangwan Xiancai.
　　 Perovskite team, Wu Feifei took Sun Wo, Yu Ya, and Deng Hu to make several batches of devices.
　　 As a result, based on the two-dimensional lead-tin mixed perovskite system, the efficiency has barely increased to 7.0% from the previous 6.6%.
　　 The room for further improvement is very small.
　　 So Feifei Wu directly chose to organize the article.
　　This kind of small article, with complete experimental data, Feifei Wu completed the writing and revision of the article in only one week, and successfully submitted it to the target journal ACSAMI.
　　 As for the future research direction, Wu Feifei listed several new lead-tin mixed systems.
　　 But to be honest, Wu Feifei doesn't think the several directions she talked about are better ones. She just puts forward the directions first and let Sun Wo do something about it. If they can succeed, they can say otherwise, at least they can't stop work.
　　 The main reason is that Feifei Wu’s recent scientific research ideas are somewhat lacking. This time I went to a beautiful country and planned to take the opportunity of the MRS meeting to see if I could find ideas from other people’s reports and posters to find a high-quality research direction.
　　 In the current photovoltaic field, the popularity of perovskite photovoltaics is still very high.
At this MRS conference, there are many big shots from the perovskite field, many of them are well-known scholars who have published articles on the CNS at home and abroad. There is something missing in their hands, which is enough for others to drink. Mouth soup.
Compared with the perovskite field, there are not many people in the organic photovoltaic field in China who participated in the MRS conference every year. The main reason is that the organic photovoltaic field is not a very popular field, so there are not many big men who report at the conference. .
　　 And if there is no big boss to make a report, it is difficult to attract ordinary researchers to pass.
　　Because of the meeting, on the one hand, it is to listen to the reports of the bosses and find the future research direction. On the other hand, it is also to make contacts and establish cooperative relationships between researchers.
　　 Without a big boss, the willingness of ordinary researchers to participate in the conference will be reduced a lot.
　　 Besides, domestic researchers have to spend a sum of money to attend conferences abroad, including round-trip air tickets, hotels, meals, conference registration fees, and participating in an international conference, almost 20,000 to 30,000 soft-sister coins.
　　Although most of this cost can be reimbursed, if you come out to hold two international conferences a year, you will spend 50,000 soft sister coins a year. It is impossible for most weak chicken research groups to have so much travel expenses to be reimbursed.
　　 Like a four-year project of 800,000 yuan, the travel expenses are only about 10%, which is about 100,000 yuan in four years.
　　 As for the project, even a professor can't pat his chest and say that he can apply for it.
　　 Therefore, there are barriers to participate in international conferences.
　　 Unless the tutor is not short of money, he can participate at his own expense. Otherwise, for a research group that has no projects at hand, the students in the group are basically insulated from going abroad to attend meetings.
　　 Although the number of scholars in the field of organic photovoltaics was bleak in the past years, the situation this year should be different.
　　 Because Xu Qiu's team has repeatedly made breakthroughs in the field of organic photovoltaics, the heat of the field of organic photovoltaics is now rapidly rising.
　　 Now Xu Qiu will be speaking at the MRS conference. This year, there will be more researchers in the field of organic photovoltaics than in previous years.
　　 At least as Xu Qiu knew, Gong Yuanjiang, Feng Shengdong, and Ronald would all be there.
　　 Chen Wanqing and Duan Yun, their graduation thesis has been written, and uploaded the blind review version of the paper, Wei Xingsi did not get stuck with them, and let them pass the review.
　　 The next step is to check the duplicates by the department and the department for review. Because it is all blindly reviewed, it is relatively easy to do. There is no need to manually find the review experts, and the department will do it directly.
Based on Xu Qiu's laminated system and the results obtained by Ronald's team, 　　 Tianqing began to organize articles on the "device structure of laminated devices, the correlation between interface charge recombination and device performance". The current progress is...10%.
　　 Tian Haru is still paddling as always. She belongs to one of the special groups that have low effort but have a lot of scientific research results.
　　 To be honest, this relaxed state is quite enviable, but reality does not allow people to stop working hard.
　　 This is related to historical reasons and the current situation. The former is due to the tradition of flower growers, and the latter is the price that the latecomers have to pay to catch up with the first movers.
try{mad1('gad2');}catch(ex){}　　 Xu Qiu took a few days off after posting the article.
　　 Of course, he is not completely idle, mainly to improve the PPT and lecture notes of the report at the MRS meeting.
　　 When Xu Qiu submitted a manuscript to MRS before, many of his work had not yet been published. Now he wants to put the latest work progress on it.
　　 includes two articles. Anyway, as an invited expert, I have 30 minutes of lecture time, and I can talk more about it, but I don’t have to worry about overtime.
As for the general content of the two submissions, Xu Qiu also sorted it out, but it was not included in the official presentation PPT. If he met acquaintances, he could share these unpublished work with them. If you are a stranger, forget it. , The defensive heart is indispensable.
　　 Speaking of it, Xu Qiu was still preparing for the return of the review comments in mid-to-late March. As a result, the review comments have not been returned until the end of March. This work has been reviewed for more than two months.
　　 However, there is no way, who asked him to vote.
　　 The others in the organic photovoltaic team continued their original experimental work after Xu Qiu finished submitting the article.
　　 Han Jiaying's PTQ2 system articles have been sorted out and voted out, the target journal JACS.
　　 Now the school girl's ability to write articles has also been cultivated. Compared with the time when I first joined the research group, my writing skills have improved a lot. Basically, the articles written do not need to be revised.
　　 Next, the school girl intends to continue the research of PTQ series donor materials. On the basis of PTQ1, fluorine atoms, chlorine atoms and alkoxy side chains are respectively introduced into the Q unit to develop PTQ3, PTQ4, and PTQ5 donor materials.
Although the materials of the previous L2, L6, and S1 series also showed good performance, they are other people's systems after all, and it can be used once in a while. If they are forced to study, it is a bit of "malicious touch porcelain", and there is no such thing. necessary.
　　 The large research groups in the scientific research circle generally focus on a certain subdivision and will not easily change the research field, which is also the reason.
　　 If the directions are frequently changed, if the research directions of the two major research groups accidentally overlap, it will cause a waste of scientific research resources.
　　Hello everyone, our official account will find gold and red envelopes every day as long as you pay attention to it, you can receive the last benefit at the end of the year. Please seize the opportunity of the official account.
　　 Wu Shengnan is very happy recently.
　　 Although Xu Qiu's two CNS-level articles are not the second work, she "inherited" the nine Y series materials Y11-Y19 from Xu Qiu, and can sort out at least two or three AM-level work.
　　 If you exaggerate the nine systems, you can even produce nine small articles in the second district. However, the post-doctoral sister’s pursuit has become higher now. UU reading www.uukanshu.com is reluctant to go to the second district.
　　 According to this development, Wu Shengnan has the opportunity to stay in school.
　　 Of course, the probability is still more difficult, she and Xu Qiu's situation is still different.
On the one hand, Xu Qiu's master's degree and Ph.D. are both at Magic City University, which belongs to the "primary department" of Magic City University. However, the school with the first degree of post-doctoral elder sister is still a little bit behind Magic City University. .
　　 On the other hand, post-doctorate sisters do not have a job that can
finish the final word
, in other words, there is no CNS, and no job at the level of a big magazine.
Now the scientific research circle is getting more and more volume. When Wei Xingsi returns to China, the era when a few AM can enter the Modu Comprehensive University has passed. If he returns to China now, maybe he can only enter a regular 985, and the published work does not contain "N". "It is quite difficult to get involved in the scientific research circle.
　　 In addition, for the same research group, if the number of people staying in school is large, it may also cause some undesirable effects. The department will also consider this factor.
　　Mo Wenlin continues to work on the preparation of Y series laminated devices. Now the device efficiency of this system has increased from 15.5% to 16.0%.
　　 The rate of performance increase has begun to slow down, and the high probability is that the bottleneck has been reached.
　　 The idea to solve this problem was found by Xu Qiu before, and that is to develop ultra-narrow band gap Y series materials.
　　 Therefore, after discussing with Wu Shengnan, Mo Wenlin and Wu Shengnan decided to try to develop an ultra-narrow band gap Y series material, named Y21, and apply it to laminated devices.
