Chapter 495: The beautiful country

After a full meal, the three returned to the hotel to rest for a while, and then went to the MRS venue to listen to the report.
　　 Throughout the afternoon, Xu Qiu and Han Jiaying moved around in various lecture halls.
　　 Although I have met many scholars who are unfamiliar with flower growers, there is not much exchange between them.
　　 One is because the researchers who grow flowers are usually shy.
　　Secondly, the unfamiliar researchers encountered at this comprehensive conference have a high probability of different research fields. If the exchange is forced, there will be a scene similar to this:
　　 "Are you from a flower planter too?"
　　 "Yes, which school do you come from?"
　　 "I'm from the Magic City University."
　　 "Oh, I am from Jiaotong University, it's a coincidence, it's all lewd... By the way, what are you in?"
　　 "I do organic photovoltaics, how about you?"
　　 "I am doing topology and quantum phenomena in intermetallic compounds and heterostructures."
　　"..."
　　"..."
　　 The topic went cold.
　　 This kind of social networking is invalid. After chatting for a long time, there is nothing to gain. With this little chat time, it is better to listen to a report.
　　 Besides, to be honest, the cross-domain and cross-school "connections" established between students are not of much practical use. Even if you add a WeChat friend, most of them belong to the kind that accumulates dust on the friend list all the time.
　　 Effective contacts in the scientific research circle usually take the initiative to find partners who can form complementary advantages with their own research group.
　　 For example, several of Wei Xingsi’s main collaborators, Feng Shengdong and Ronald, can provide device mechanism support and perform various characterization methods including TAS, TRPL, CELIV, and TOF;
　　 Gong Yuanjiang has been working in the domestic organic photovoltaic field for many years, and cooperation with him can increase Wei Xingsi's voice in the domestic organic photovoltaic field, and it will be easier to pass when applying for fund projects.
　　 Of course, these are only from a utilitarian point of view. It is not excluded that some people will enjoy making friends.
　　 However, Xu Qiu and Han Jiaying are both introverted personalities. If they are acquaintances, they can let go. If they are strangers, they usually don't take the initiative to contact them.
　　 After listening to the afternoon report, Xu Qiu and Han Jiaying met Wu Feifei.
After 　　, they did not go out to search for food, but went back to the hotel to rest for a while, and then returned to the venue again.
　　Because the exhibition center will hold poster exhibitions, supplier exhibitions and job fairs starting at 7pm.
　　 At that time, Feifei Wu’s poster will be exhibited, and someone needs to be beside the poster to explain to other interested researchers.
　　The most important thing is that a free buffet dinner will be provided at the evening show.
　　 The cost of food and beverage in the beautiful country is still relatively expensive. Except for the donuts, the rest of the restaurant starts at 10 dollars per person for a random meal, which is equivalent to going out to eat in the country every day, and the purse is still a bit overwhelming.
　　 Now there is a buffet to rub, there is no reason not to rub.
　　 When the three of them came to the exhibition hall, Xu Qiu found that there was already a huge crowd in an exhibition hall the size of a football field. The number of people present was estimated to be hundreds of people.
　　 Xu Qiu was taken aback by the number of people. He estimated that it is impossible for everyone to come here to participate in the exhibition alone. There must be many people who are also thinking of Cengfan.
　　 The organizer of the conference is also witty. Taking into account this situation in advance, he chose a large venue for the exhibition hall, otherwise it may not be able to accommodate so many people.
　　 Inside the venue, there are rows of bulletin board-style exhibition boards, with corresponding numbers on them, and posters in order for display.
　　 Xu Qiu and they followed the number given in the MRS conference manual and found Feifei Wu’s poster.
　　 However, most of the people who enter the venue at this time are not interested in the exhibition, but in the buffet provided by the conference party.
　　 Xu Qiu and the others did the same. After stepping on the Wu Feifei poster, they went straight to the central buffet area.
　　The variety of dishes here is not very rich. There are three types of meals, including toast, barbecue steak, and something that looks like fried pho.
　　The common feature of these dishes is that there is no soup, so you can eat dinner while participating in the exhibition.
　　 In addition, there are three kinds of beverages available, namely black tea, coffee and wine.
　　 Although the variety is not rich enough, the taste is good, and it is full.
　　 After dinner, Feifei Wu stayed in front of her poster, while Xu Qiu and Han Jiaying went out to see posters exhibited by others.
　　 After walking around for half an hour, Xu Qiu found that the contents of other posters corresponded to the representative work that the research group had published in the past year.
　　In other words, if it is a normal colleague who reads the literature on a regular basis, they have basically seen these jobs.
　　 Therefore, these posters may not be of great help to the colleagues. They are more able to attract the attention of other researchers in different fields. Maybe you can cooperate, engage in interdisciplinary, and work together to make big news.
　　 Sometimes, it's really a fan of the authorities, and it's hard to get out of it because it's stuck in the previous mindset.
　　 And if the disciplines intersect and collide, it is very possible to find another way to solve the current predicament in one fell swoop.
　　 Of course, if you had any doubts when reading peer articles before, and now you just met at the conference, you can also directly find the author of the article to communicate.
　　 For example, let’s explore how to "reverse the cooked eggs with your mind, and then you can hatch chickens."
　　 In addition, each poster has the LOGO of the corresponding school. There are some famous schools abroad and many famous schools in China.
　　 Xu Qiu basically collected the LOGOs of major domestic TOP universities in the poster, including Qingbei University, Magic City Comprehensive University, Magic City Jiaotong University, Zhejiang University, etc...
　　 Finally, Xu Qiu noticed that the total number of posters in the venue was still quite large.
　　 Moreover, this is the first day of the poster exhibition. There will also be a poster exhibition in the next two nights. If the three days add up, the number of posters is estimated to be thousands.
　　According to Wei Xingsi, if the MRS meeting submits an oral report to the main venue, even if there is no 15+10 minute oral report opportunity, there is a high probability that a poster will be displayed.
　　 In other words, as long as you have carefully prepared and submitted your MRS, you can almost guarantee a poster display opportunity.
　　 This is also very easy to understand. For the conference party, it is definitely inclined to have as many participants as possible.
　　 Because there are more people, on the one hand, you can get more registration fees, on the other hand, it can also stimulate a wave of tourism in the corresponding cities.
　　In fact, the logic of holding various international conferences is similar to that of the Olympic Games.
　　 Although the investment in the construction of Olympic venues and Olympic villages is huge, countries are still fighting for a place in the Olympic Games.
　　 The Neon Country even regards the Olympics as a life-saving straw for them to get rid of the curse of "losing thirty years" and revive the economy.
　　 Of course, if it's useful, let's talk about it separately.
　　 After visiting the poster exhibition, Xu Qiu and Han Jiaying continue to the next exhibition area-the supplier exhibition.
　　 This is similar to a normal science and technology exhibition, basically selling instruments, such as ultra-fast 3D printers, etc., mainly focusing on the cooperation between the scientific research circle and the industrial circle.
　　Like the instruments developed by Blue River, some of them will be put on some domestic science and technology exhibitions to look for cooperation.
　　 MRS is only an exhibition with relatively high specifications, and instrument suppliers have more opportunities to find cooperation.
　　 However, these have little to do with Xu Qiu and Han Jiaying, so they just wandered around a little bit, and then moved to the last stop-the "job fair".
　　 The "recruitment fair" sounded very big, but when Xu Qiu and the others came to the scene, they found that there were actually a few panels like the poster exhibition, with various advertisements hung on them.
　　 For example, journals recruit editors; the University of Toronto recruits assistant professors; the Institute of Chemistry of the Chinese Academy of Sciences recruits postdoctoral fellows, etc...
　　 Xu Qiu really didn't expect that the Chinese Academy of Sciences would actually advertise here.
　　 But thinking about it, it doesn’t seem strange.
　　 As long as it is related to scientific research in China, whether it is a treeworm, Tieba or BBS, or even a postgraduate tutor's Tucao website, there will be a variety of small advertisements after recruitment.
　　 For post-doctoral skilled workers who have been trained, they are very popular with the bosses of major research groups.
　　 At the same time, this also shows that the domestic post-doc gap is still relatively large, the demand is relatively high, but the supply is insufficient.
　　According to Xu Qiu's observation of the Materials Department of Modu University, the number of research groups with postdoctoral fellows is not more than 20%, and probably about 10%. Most research groups cannot recruit postdoctoral fellows.
　　 The reason is that Xu Qiu believes that firstly, the proportion of conversion from doctoral to postdoctoral is not high.
　　Most doctoral students will find that they do not have very NB scientific research capabilities during graduate school. After their doctoral degree, they will tend to change careers, such as developing in industry and entering companies in related fields to engage in research and development.
　　 By the time of Ph.D. graduation, you have to make a choice. Unlike undergraduates, you can choose to study for a master's degree. After a master's degree, you can choose to go to a doctorate to "escape the choice."
　　 After graduating from a Ph.D., if you don’t choose to switch jobs immediately, but first take a post-doc post and then switch jobs, the sunk cost will be too high.
　　 Because they missed the school recruitment and wasted two years, they are often in their 30s, close to 35 years old...
　　In today's society, a person’s age is a very important indicator. Except for a few industries such as doctors, lawyers, and the system, most industries are actually eating their youth.
　　 Even the IT industry, which seems to be relatively
frontier
, is still eating a youthful meal. If programmers cannot be promoted to management at the age of 35, they will most likely be optimized or their salary will be severely degraded.
　　Because whether it is IT or most other industries, it is essentially an industry that competes for physical strength and learning ability.
　　 At the age of 35, physical function declines. Whether it is physical strength or learning ability, it is impossible for a young man in his early 20s to fight.
　　 And the company’s mid-level and high-level pits are limited and cannot accommodate so many "talents", naturally a large proportion of old employees will be optimized.
　　 Actually, these optimized old employees are not necessarily that they are not good enough, but that others are better, and they lost to the internal volume.
　　In the future, with the aging of the population and the disappearance of the demographic dividend, for those born in 00s and 10s, the 35-year-old age limit may be loosened.
　　Because when they are 35 years old, there are not enough young people born in the 10s and 20s who are competing with them.
　　 By then, the "35-year-old curse" may be changed to "40-year-old curse" and "45-year-old curse".
　　 But for the post-80s and post-90s who are the main force in the workplace at this stage, 35 is still a real threshold.
　　 The postdoctoral fellow reaches the age of 35, and it is similar. If the scientific research ability is insufficient and the faculty cannot be mixed into the university, or the university fails the "promotion or leave" assessment, the following days will be very difficult.
　　 The age exceeds the limit, civil servants within the system cannot enter, companies may not be admitted, and colleges and universities cannot enter...
　　 Maybe you can do a freelance job, set up a booth on the flyover, and stick a film?
　　Or go back to the countryside to raise pigs scientifically, and study the "impact of sunspot activity cycle on postpartum care of sows"?
　　 Or publish a book called "The Years I Do Scientific Research"?
　　 Of course, if it were "The Years I Do Scientific Research", it is likely to be on the street, and it is changed to "The Stories I Have to Tell the School Sisters in the Laboratory in Those Years", which is probably better.
　　 In addition to the relatively low conversion rate of Ph.Ds to post-doctorate, the domestic post-doctoral candidates cannot be recruited. It is also because post-doctoral studies in China are actually quite embarrassing in terms of positioning.
　　 On the one hand, if you don’t have overseas study experience, it is harder for postdoctoral postgraduates to find a faculty position in a college, unless they have
hard goods
, such as CNS, or a number of top journals.
try{mad1('gad2');}catch(ex){}　　 Otherwise, you can only go to two or three books, or a vocational college, which means that your chances of promotion in the future are extremely slim.
　　Because professors and students in colleges and universities accomplish each other's achievements, no matter how NB the tutor is, it is useless if there is no student with the same NB.
　　 Nowadays, we all emphasize the cooperation of a group. The higher the grade of the school, the higher the probability of recruiting high-quality students.
　　 On the other hand, it is basically difficult for post-doctoral students in China to carry out their own work.
The situation of Wu Shengnan in the 　　 image group is a special case. She followed Xu Qiu in a lot of articles.
　　 And most of the domestic post-doctoral post-doctorate, after joining the group, the daily work content is to help the boss write a book, write a book, write a book...
　　Even if you can do experiments, you will often give your boss the designated research direction to realize the boss's scientific research ideas. The autonomy is relatively small. After all, the post-doctoral salary of 20W+ is not for nothing.
　　 Of course, except for those who have the ability to post the post, they can be on an equal footing with the boss.
Although the scientific research circle is also ranked by seniority, it is often something that needs to be considered when reaching the highest level. Before being a full professor and getting a "hat", as long as you have the strength and the output of scientific research results Have the right to speak.
　　 However, having said that, Ph.D. graduates who are really capable are basically unlikely to find post-doctoral post in China...
Most domestic scholars who are determined to engage in scientific research in the future will choose to find post-doctoral positions abroad, and then wait for the post-doctorate to leave the station, either stay abroad to teach, or return to the country to go among the "thousands" or "thousands." The talent project of this kind is introduced back to the country.
　　 In other words, after graduating from a Ph.D., people who choose postdoctoral positions in China, if it is a bit ugly, most of them are "weak people left behind."
　　 Although the truth may be cruel, the truth is like this.
　　In terms of basic science research, at this stage, China still lags far behind beautiful countries in terms of scientific research conditions and scientific research environment.
　　 After all, the foundation accumulated by others over 200 years cannot really catch up in 30 years.
　　 Of course, the gap between the two is also shrinking at a speed that the naked eye can see. This can be seen from the fact that a large number of scholars have returned to China from abroad in recent years.
　　Perhaps one day in the future, domestic scientific research can break the blockade and achieve a surpass, allowing scholars from all over the world to come on pilgrimage.
　　 The exhibition ended, Xu Qiu and the three returned to the hotel.
　　 They have been in Phoenix for two days, but basically they have never left the surrounding area of ​​the venue, so they plan to spare a day to stroll around the Phoenix city tomorrow, on the 4th.
　　 On the one hand, there will be no important report to listen to tomorrow. In fact, in a strict sense, in a conference like MRS, there is no report that you must attend except for the report you want to give a speech.
On the other hand, if Wei Xingsi’s visit from UCSB ends on the 5th and comes to Phoenix to attend the MRS meeting, it’s not easy to go out. Although Mr. Wei said that he can take time to play, but if he is in front of him It's not a very good choice to go to the water.
　　 April 4th, morning.
　　 Xu Qiu's first stop was the Desert Botanical Garden, and their choice of travel was by bus.
　　 There is a bus stop not far from the venue, where you can take a bus directly to the Desert Botanical Garden.
For the 　　 fare, a one-way ticket is fixed at US$1.5, and you can also purchase a single-day unlimited ride ticket, or a "day pass", at a price of US$6.
　　 Xu Qiu and the three people bought three day cards with a credit card on the self-service machine next to them, and then began to wait for the bus.
　　 The public transportation in Phoenix does not seem to be very developed. The bus lines are designed to be very long, but the frequency is very few. A bus takes about half an hour, and there are not many people using it.
　　 Xu Qiu At this platform, apart from the three of them, only the other two white people were waiting for the bus together, and both of them had MRS tags hanging around their necks. It seemed that they had also come to participate in the meeting and then went out to play.
　　 After waiting for about twenty-five minutes, a tall bus finally arrived late.
　　 There is a bracket in front of the bus with a bicycle on it. There should be cyclists taking their bicycles on the bus together.
　　 Everyone got on the bus in an orderly manner, and Xu Qiu took the initiative to show the ticket to the middle-aged white driver.
　　 But the other party didn't seem to have the intention to check the ticket. Xu Qiu also collected the ticket and found a spare three-row position to sit side by side with Han Jiaying and Wu Feifei.
　　 They need to take a total of more than 20 stops to reach their destination, which is quite far away.
On the way, Xu Qiu was also observing and comparing the similarities and differences between public transportation in Phoenix and China.
　　 First of all, the distance between the bus station and the station in Phoenix is ​​relatively short, and the number of people using it is relatively small. Therefore, if there is no one getting on or off the bus at the corresponding station, the driver will not stop.
　　 And the way to remind the bus driver if anyone wants to get off the bus is relatively simple—
　　 Inside the bus, there is a simple small rope running through the car. Passengers who want to get off the bus can pull the small rope nearby. As long as the small rope is gently pulled, the horn of the bus will sound and other passengers can also hear it.
　　 is somewhat similar to the bell ringing on a domestic bus.
　　Secondly, the beautiful country buses provide adequate protection for the disabled and people with special needs.
　　 The bus stopped at a platform on the way. With the sound of "chi-" air valve, the board of the bus's back door slowly dropped to be level with the platform outside.
　　 Then, a middle-aged white man aged about 50+ "driving" on the bus in a wheelchair by himself, and no one else took care of it.
　　 When the wheelchair got on the bus, there was another "chi-", the board of the back door slowly lifted, and the wheelchair drove into the carriage.
　　 Seeing this scene, Xu Qiu was still a little shocked.
　　 In China, if a disabled person in a wheelchair is thrown outside alone, no one will rest assured, let alone let them take a bus.
Moreover, although many blind paths and barrier-free passages in China have been set up, in actual use,
the blind path suddenly breaks while walking, or eventually leads to a dead end
,
the of the barrier-free passage is too large, and the disabled The situation where people cannot go uphill on their own.
　　 However, having said that, this is also the price that flower growers must pay for their rapid development.
　　In the early stages of development, additional investments such as blind roads and barrier-free passages that have no obvious boost to economic development will be discarded, or low-standard construction will be implemented.
　　 This world is so "fair". If you want to get something, you will inevitably lose something.
　　 Including the use of demographic dividends, engineer dividends, and higher housing prices to accelerate economic development by flower cultivators over the years, it is actually a kind of borrowing for the future.
　　 The declining birthrate, low vitality of young people, severe involution, and slowing economic growth in the current society are debt repayments in a sense.
　　 Finally, Xu Qiu also saw a lot of "cars making people" on the road, including yesterday when he and Han Jiaying crossed the road to the MRS Convention and Exhibition Center, he was also courteous by the passing vehicles.
　　 In addition, Xu Qiu also found that the beautiful Chinese are not so quasi-preserving the red and white lights in front of the crosswalk.
　　 When some beautiful Chinese cross the road on the crosswalk, if they see that there is no car around, even if it is a red light, they will walk straight over.
This kind of behavior, if placed in the country, will definitely be regarded as immoral behavior. Some people may have darker thoughts: "Dare to run a red light and hit him." Some people even suggest: "Pedestrians are hit by a red light. Full responsibility".
　　 But if you think about it from another angle, when the traffic rules of the beautiful country are formulated as "comfort to pedestrians as the first principle, traffic lights as the second principle", the appearance of this behavior becomes reasonable.
　　 In other words, the red and white lights are just a reminder signal for pedestrians. Pedestrians on crosswalks have absolute right of way.
　　 At this time, there is no such thing as running a red light.
　　Under different cultural backgrounds, or under different periods of the same cultural background, it is difficult to use the same set of moral standards to restrain and judge.
　　 For example, a certain domestic Nobel Prize winner once said: "It is immoral in a sense to pursue a standard of living beyond a well-off society."
This sentence may seem strange at first glance, but if we take "let some people get rich first, then drive the other people to become rich, and finally achieve common prosperity" as the moral benchmark, and then rank it according to the quality of life of subsistence, well-off, and surpassing well-off. You will find:
Most groups in China are still in the stage of just getting rid of poverty and barely getting enough food and clothing. Some people who have already achieved a well-off life, or those who "get rich first", have not "brought other people to get rich", but have pursued themselves far beyond A well-off life is indeed an immoral behavior.
Because the speed of modern scientific and technological breakthroughs is very slow, the fourth industrial revolution has been delayed, and the total resources of social production have risen very limitedly. Therefore, at this time, if a person realizes a life from a well-to-do life to a life far beyond that of a well-off life, it may be possible It means that 10,000 people have fallen from a well-off life to a subsistence life.
　　Of course, this kind of ethics will greatly suppress the momentum of people's efforts and is not conducive to economic development.
For this reason, such moral codes have almost been abolished, especially in the first-tier cities. Now they are advocating "996, and it's all done!", "What is love? I just want to make money!", "Struggle! Burn!" Right! Those who fled Beijing, Shanghai and Guangzhou, your next generation will still come back!"
　　...
　　 The three arrived at the Botanical Garden and each purchased a ticket for 22 dollars to enter the garden.
The Botanical Garden in Phoenix is ​​quite famous. According to the information they have checked before, it is the largest desert botanical garden in the world. There are more than 4,000 species and more than 21,000 desert plants growing inside, of which 139 are rare and threatened. Or an endangered plant.
After the field visit, Xu Qiu felt that it was worth the ticket price of more than 100 soft sister coins. There were all kinds of colorful prickly pears, cacti and other desert-specific plants, as well as some small animals such as butterflies and hummingbirds. .
　　 The two girls were also happily playing, taking pictures and group photos everywhere, and Xu Qiu became their exclusive photographer.
　　 Wandering in the botanical garden for more than an hour, the time was close to noon, and the temperature began to rise gradually.
　　 At this time, the outdoor temperature is very close to 40 degrees Celsius, and Wu Feifei’s mobile phone even activated its self-protection mechanism because of overheating, and directly restarted automatically.
　　 Before, the three of them spent most of their time in hotels and conference venues. They could use the air conditioner at any time. Now they have been running outside for a whole morning and finally saw the power of Phoenix.
　　 Therefore, they changed their itinerary and cancelled their plan to go to Arizona State University in the afternoon. They took the bus directly to a commercial area on the bus route, settled for lunch, and returned to the hotel to lie down.
　　 has adapted to the milder climate in the capital city, and now it is very uncomfortable to come to Phoenix in the desert climate.
　　Walking outside, how can I stay in the hotel to have air conditioning comfortable.
　　 April 5th.
　　 Wei Xingsi came to Phoenix, he first met with Xu Qiu and the others, and exchanged the recent progress, mainly because the latter reported what he had recorded when he heard the report in the past few days.
Halfway through, Wei Xingsi mentioned: "A few days ago, I sent an email to the editor of "Science". I originally wanted to make an appointment, but the other party was inconvenient, so I didn't make an appointment, but the other party said that they are more optimistic about our work. , Now waiting for the comments of the last few reviewers."
　　 In the morning, Wei Xingsi took Xu Qiu and the others to meet with acquaintances such as Gong Yuanjiang, Feng Shengdong, and Ronald one by one. They greeted them out of courtesy without much communication.
　　 During the rest of the time, Xu Qiu and the others listened to the report as usual, but with a small tail like Wei Xingsi, it was not convenient for paddling.
　　 It is worth mentioning that the arrival of Wei Xingsi has also greatly improved Xu Qiu's food situation.
　　 After all, it was the instructor who brought the students out for a meeting. It must be a treat by the instructor, and the place to eat is not too bad, at least not to eat donuts.
try{mad1('gad2');}catch(ex){}　　 At noon, Wei Xingsi called a taxi, took Xu Qiu and the three to a place similar to Chinatown, and found a Sichuan restaurant to eat.
　　 The plaques and decorations on the outside are all used in a very exaggerated Chinese style, and there are elements of flower family style everywhere, probably to highlight that this is a Chinese restaurant.
　　 The owner who opened the shop here is also from the Magic City. As soon as we meet Wei Xingsi, he and the other party "see my fellow villagers", using the words of Magic City to communicate with each other.
　　Wu Feifei is a native of Zhejiang Province, and Han Jiaying is a native of Jiangsu Province. Both of them can understand Mordu dialect. Only Xu Qiu is from the north, and he is confused.
　　 However, it doesn’t matter anymore. No matter how hot the conversation is, it will be dinner after all.
The business in 　　 is pretty good. There are more than 20 tables in total, and the attendance rate is over 70%.
　　About half of the customers who come here are white people, and most of them come to eat in the form of families.
　　 About half of them are yellow people. It seems that they are basically people from China who come to participate in the MRS meeting. Many of them also carry tags issued by MRS on their necks.
　　 I didn’t see any of the black people.
　　 Wei Xingsi ordered the signature spicy chicken, boiled pork slices, mapo tofu and fish-flavored pork, with four bowls of rice.
　　The food style is similar to domestic Sichuan cuisine.
　　 The taste is not very spicy, and there is no authentic Sichuan restaurant in China.
But it is understandable that this is a beautiful country after all. Most people do not eat spicy food. If you open a restaurant here, you need to modify it according to the tastes of the locals. If you are used to domestic Sichuan cuisine, you will naturally feel uncomfortable when you come here to eat. habit.
　　 After eating, everyone returned to the MRS venue and listened to the report for another afternoon.
　　 In the evening, Wei Xingsi took Xu Qiu and the others to a relatively high-end American restaurant around the venue. It mainly serves hamburgers, and the price is still a bit expensive.
　　 A burger costs 38-68 dollars, a fish and chips costs 22 dollars, and a fruit salad costs 28 dollars.
　　 Finally, four people ordered four burgers, one fish and chips, one fruit salad and four glasses of beer.
　　 When it comes to drinks, Xu Qiu and Han Jiaying, who seem to be relatively young, have their passports checked again.
　　 When they were investigated, Feifei Wu’s expression was a bit complicated...probably a little envious.
　　 The burgers in this shop are very large, about 20 cm in diameter and 30 cm in height.
　　Because the burger is too big to stand on its own, the shop has an iron stick to fix it from top to bottom.
At the bottom is a layer of bread, then a layer of onions, tomatoes and sauces, then a layer of cheese, then a very thick layer of beef patties, and then another layer of cheese, a very thick layer of beef patties , A layer of cheese, a layer of onions, tomatoes and sauces, and a layer of bread.
　　 Such a big burger, Xu Qiu estimated that even if O'Neill came over, opened his mouth and dislocated his jaw, he would not be able to swallow it whole.
The taste of 　　 burgers is also very good, at least the domestic Kaifeng cuisine is completely exploded, after all, the price is there.
For the 　　 beer, it is a locally produced dark beer, and the taste is quite satisfactory. The taste is not strong, but it is a bit bitter.
　　 April 6th.
　　 Xu Qiu woke up early, dressed in formal clothes, first checked the presentation PPT in the hotel again, and then went to the MRS venue with Wei Xingsi, Han Jiaying, and Wu Feifei.
　　 The report officially started at eight o'clock, but at a quarter past seven, people had already entered the venue one after another.
　　 Including the chairperson of today’s meeting, Su Haibo, a Chinese researcher from the Massachusetts Institute of Technology, is about 50+, male, slightly Mediterranean.
　　 When Xu Qiu was reading high-end literature in the field of organic photovoltaics, including the big magazine of Nature, he often saw the name of Su Haibo and knew that this was an ancient bigwig in the field of organic photovoltaics.
　　 Why is it an ancient boss? It's because Xu Qiu is almost the only boss in the new generation. In addition, Wei Xingsi has taken his light, and now he is considered to be a big boss.
　　 Xu Qiu can be said to have driven the entire team with his own power, and made the field of organic photovoltaics reach a big step.
　　 At 7:55, Xu Qiu stepped onto the podium.
Su Haibo made a full introduction: "Today's first report is Xu Qiu from Magic University. His tutor is Professor Wei Xingsi. His main research direction is organic photovoltaic devices based on ADA-type non-fullerene acceptor materials. ...We welcome!"
　　 There was a burst of warm applause from the audience.
　　 Xu Qiu stood on the podium and looked at the dark crowds underneath. Some of them were familiar faces in China, but more were strange scholars from all over the world.
　　 However, he doesn't feel too nervous. The scientific research experience over the years has greatly improved his on-the-spot speaking ability.
　　 Xu Qiuyou remembered that when he was in high school, he would shake his legs when he talked about a topic on the podium in the class, and now he feels comfortable even reporting at a top international academic conference like MRS.
　　 took a deep breath, Xu Qiu began to talk about the work he has led over the past year:
　　 "In the first stage, the origin of ITIC, we modified the conjugated main chain of IDT based on IDT-ICIN material, changed it to IDTT, obtained IDTT-ICIN, and named it ITIC..."
　　 "At this time, the non-fullerene organic photovoltaic field has entered the stage of 10% efficiency."
　　" In the second stage, based on the ITIC receptor, four optimization paths were derived:
"The first one is to modify the A unit, that is, the ICIN end group, to obtain several receptor materials represented by IT-4F, IT-M, and IT-4Cl.
"The second one is to modify the side chain of the central D unit to obtain materials such as IDIC and m-ITIC.
　　"The third is to modify the main chain of the central D unit to obtain materials such as FNIC, 4TIC, IHIC, etc.
　　" Article 4, imitating the IDTBR structure, designing the structure of AπDπA, and obtaining a series of materials.
　　"At the same time, the donor materials were also designed, including H series, J series donor materials...
　　 "At this time, the non-fullerene organic photovoltaic field has entered the stage of 12% efficiency, which is equal to the traditional fullerene system."
　　 When talking about this, Xu Qiu noticed that Wei Xingsi in the audience stood up suddenly after looking at the phone, with an expression of excitement.
　　 However, Teacher Wei seemed to realize that this was the venue, and soon sat down again, and apologized to other scholars around him.
　　 Although Xu Qiu had some doubts about Wei Xingsi’s actions, he did not interrupt his speech and continued to report:
"In the third stage, on the one hand, we combine the non-fullerene receptor system with various concepts, including translucent, scratch-coated, flexible, and ternary blend devices, paving the way for future commercial applications; on the other hand, On the other hand, based on the experience of the second stage, we adopted multiple strategies at the same time, continuously adjusted and optimized, and finally got the best J2: IDIC-4F system..."
　　 "At this time, the organic photovoltaic field has entered the stage of 13.5% efficiency, breaking the world record of efficiency at that time."
　　 At the end of the speech, Xu Qiu briefly mentioned the results of the recent experimental work, and did not put the specific details on the PPT. After all, the article has not been published, so it is not suitable for this kind of conference:
　　 "In the fourth stage, through the preparation of laminated devices and the development of Y series acceptor materials, we have sprinted the efficiency in the field of organic photovoltaics to 17% or more than 18%!"
　　 When "18%" was uttered by Xu Qiu, the researchers in the audience immediately began to whisper, seeming to confirm each other whether they heard it wrong.
　　 You should know that among the results that have been reported, the highest device efficiency in the organic photovoltaic field is only 14%, which is the laminated device published in the "Nature Optoelectronics".
However, some people did not seem to be surprised, such as Su Haibo on the stage. He applauded and said: "The organic photovoltaic field can achieve an efficiency of 18%. It is really a heroic youth. The speech is also very good. What do you have? Do you want to ask a question?"
　　 Wei Xingsi immediately raised his hand and said with great excitement: "Xu Qiu, the opinions of the "Science" article are back, and the editor's suggestion is to accept directly! You can share the PPT you have made before with you!"
　　As soon as these words came out, other researchers in the audience were talking and whispering again:
　　 "There hasn't been an orthodox CNS experimental article in the field of organic photovoltaics for many years. I didn't expect it to be taken down by the teenager on the stage."
　　 "Furthermore, in a crushing situation, the original efficiency of 14% was directly recorded, breaking through to 17% in one fell swoop."
　　 "Not only that, the binary Y series receptor material he just mentioned corresponds to an efficiency of 18%, and it is also very possible to get another CNS."
　　Some research team bosses are working in multiple fields at the same time. Now that the organic photovoltaic field is expected to break through and become a hot field, the heart is also up: "Would you like to increase the research in the organic photovoltaic field?"
　　 Xu Qiu didn’t know what other people thought. He turned his head and asked the chairman of the meeting:
Can I continue to report? It may take about 5 minutes.

　　 "Of course," Chen Haibo made an inviting gesture: "I am the reviewer of your "Science" article. You wrote very well."
　　 "Thank you." Xu Qiu thanked him, and then found the PPT of his stacking work, gave a public speech, and again received warm applause from the scholars in the audience.
　　 After that, under the organization of Chen Haibo, Xu Qiu communicated with other researchers in the audience.
　　 As a result, I don’t know if I don’t communicate, I’m surprised when I communicate.
　　 Xu Qiu didn't expect that in this field, the big guys gathered in the audience. In addition to Chen Haibo, there are two other scholars who are also reviewers of his "Science" article.
　　 They all spoke highly of Xu Qiu's "Science" article and affirmed Xu Qiu's contribution in the field of organic photovoltaics.
　　 One of them is Stephen R. Forrest, who previously reported on 14% efficiency laminated devices in "Nature Optoelectronics", a beautiful academician of the National Academy of Sciences.
Forrest also extended an olive branch and invited Xu Qiu to do their doctoral work. After UU reading www.uukanshu.com, Xu Qiu naturally did not agree, politely refused, and Forrest was not upset, saying that if he had any thoughts in this regard later, he would be at any time. welcome.
　　 Finally, after dealing with the enthusiastic audience, Xu Qiu returned to the audience.
　　 Then, he accepted another compliment from Wei Xingsi, Han Jiaying and Wu Feifei.
　　 It wasn't until the next report that everyone's attention shifted.
　　 Xu Qiu adjusted his sitting posture, entered the system interface, and his consciousness was instantly pulled into the system space.
　　 The system space seems to have returned to its original chaotic state, and the surrounding area is colorful and black.
　　The system's prompt sound also arrived as promised:
　　 It was detected that the host published an article in any of the journals "Nature", "Science", and "Cell" as the first author/first corresponding author. The advanced task has been completed, and the permission level is +1.
　　 It is detected that the current authority level is 9 and it has reached the highest authority level.
　　 "Scientific Research Aid System" is being unbound...
　　 "Advanced Research System" is binding...
　　 After carefully understanding the functions of the new system, Xu Qiu raised his brows and withdrew from the system space.
Han Jiaying next to 　　 seemed to have noticed something, and asked in a low voice, "Brother, what's the matter?"
　　 Xu Qiu smiled mysteriously: "Nothing."
　　‘I always feel like there are so many secrets there. ’
　　 Although Han Jiaying had doubts in her heart, she did not ask.
　　 It turns out that a woman’s sixth sense is quite accurate.
　　 April 6, 2016, later generations call this day the beginning of the birth of a generation of legends.
