I Have a Research Support System

After a hearty meal, the three went back 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 went back and forth in various lecture halls.

Although I met many scholars who were unfamiliar with flower growers, they didn't communicate much with each other.

One reason is that florists are usually shy.

Second, unfamiliar researchers met at such a comprehensive conference have a high probability of having different research fields. If communication is forced, a scene similar to this will appear:

"Are you from a florist too?"

"Yeah, which school do you go to?"

"I'm from Modu Comprehensive University."

"Oh, I'm from Shanghai Jiaotong University. It's a coincidence that they are all prostitutes in Shanghai... By the way, what field do you work in?"

"I do organic photovoltaics, what about you?"

"I work on topological and quantum phenomena in intermetallic compounds and heterostructures."

"..."

"..."

The topic went cold.

This kind of social interaction is ineffective. After chatting for a long time, there is nothing to gain. With this time for chatting, it is better to listen to one more report.

Moreover, to be honest, the "connections" established between students across fields and schools are not of much practical use. Even if you add a WeChat friend, most of them belong to the kind that accumulates dust in the friend list all the year round.

Effective contacts in the scientific research circle are usually to take the initiative to find those cooperation partners who can form complementary advantages with their own research group.

For example, Wei Xingsi's main collaborators, Feng Shengdong and Ronald, can provide device mechanism support and carry out various characterization methods including TAS, TRPL, CELIV, and TOF;

Gong Yuanjiang has worked in the field of organic photovoltaics in China for many years, and cooperating with him can increase Wei Xingsi's voice in the small circle in the field of organic photovoltaics in China, and it will be easier to pass when applying for fund projects.

Of course, these are just from a utilitarian point of view, and it is not ruled out that there will be some people who enjoy making friends.

However, Xu Qiu and Han Jiaying are both introverted people. If they are acquaintances, they can let go of them. If they are strangers, they are usually not very willing to take the initiative to contact them.

After listening to the report in the afternoon, Xu Qiu and Han Jiaying gathered with Wu Feifei.

After that, instead of going out for food, they went back to the hotel to rest for a while, and then returned to the venue again.

Because starting at 7:00 p.m., the convention center will host a poster fair, supplier fair, and job fair.

At that time, Wu Feifei's poster will be exhibited, and someone needs to be beside the poster to explain to other interested researchers.

Most importantly, a free buffet dinner will be provided at the evening show.

The food and beverage costs in the beautiful country are relatively expensive. Except for donuts, other restaurants start at $10 per person for a casual meal, which is equivalent to going out to eat out every day in China, and the wallet is still too much.

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 the exhibition hall, which was the size of a football field, was already crowded with people.

Xu Qiu was taken aback by the number of people. He reckoned that it was impossible for everyone to simply come to participate in the exhibition.

The organizer of the meeting was also resourceful, considering this situation in advance, and chose a large venue for the exhibition hall, otherwise it might 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 are posted one by one in order for display.

Xu Qiu and the others followed the number given in the MRS conference manual and found Wu Feifei's poster.

However, most of the people who entered the venue at this time were 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 Wu Feifei's poster, they went straight to the central buffet area.

The variety of dishes here is not very rich. There are three meals in total, including toast, barbecue steak, and something that looks like fried rice noodles.

These dishes have a common feature that there is no soup, and you can have dinner while participating in the exhibition.

In addition, there are three beverages available, namely black tea, coffee and wine.

Although the variety is not rich enough, the taste is still good and full.

After dinner, Wu Feifei stayed in front of her own poster, while Xu Qiu and Han Jiaying went out to look at the posters of other people participating in the exhibition.

After browsing for half an hour, Xu Qiu found that the contents of other people's posters were generally representative work published by the corresponding research group in the past year.

In other words, if it is a normal colleague who regularly reads the literature, basically they have seen these works.

Therefore, these posters may not be of great help to colleagues, but more likely to attract the attention of other researchers across fields. Maybe they can cooperate with each other, engage in interdisciplinary research, and work together to make big news.

Sometimes, it is indeed a fan of the authorities, and it is difficult to get out of the previous mindset.

However, if the disciplines intersect and collide, it is very likely that they can 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 happen to encounter them at the venue, you can also directly find the author of the article for communication.

For example, discuss how to "regenerate a boiled egg with your mind, and then hatch a chick".

In addition, each poster has the LOGO of the corresponding school, some of which are famous foreign schools, and many domestic famous schools.

Xu Qiu basically collected the logos of the top domestic universities in the poster, including Qingbei University, Shanghai University of Technology, Shanghai Jiaotong University, Zhejiang University, etc...

Finally, Xu Qiu noticed that the total number of posters in the venue was quite large.

Moreover, this is the poster exhibition on the first day, and there will also be a poster exhibition on the next two nights. If the three days add up, the number of posters is estimated to be thousands.

According to Wei Xingsi, if you submit an oral report at the main venue of the MRS conference, even if you don’t get a 15+10-minute oral report opportunity, there is a high probability that you will still have a poster exhibition opportunity.

In other words, as long as you submit a manuscript to MRS after careful preparation, you will almost be able to get a poster exhibition opportunity.

This is also easy to understand. For the meeting party, it is definitely the more people who tend to attend the meeting, the better.

Because the more people there are, on the one hand, they can get more registration fees, and on the other hand, they can 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.

Neon Nation even regards the Olympics as a straw for them to get rid of the curse of "lost thirty years" and revive the economy.

Of course, whether it is useful or not is another matter.

After visiting the poster exhibition, Xu Qiu and Han Jiaying continued 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.

For example, some of the instruments developed by Blue River will be put on some domestic science and technology exhibitions to seek cooperation.

In the case of MRS, it is only a relatively high-standard exhibition, and instrument suppliers have a greater chance of finding cooperation.

However, these had little to do with Xu Qiu and Han Jiaying, so they just strolled around for a while before moving on to the last stop - "job fair".

The "job fair" sounded grand, but when Xu Qiu and the others came to the scene, they found that it was actually a few display boards like a poster exhibition, with various advertisements hanging on them.

For example, the Solar RRL journal recruits editors; the University of Toronto recruits assistant professors; the Institute of Chemistry, 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 when you think about it, it's not surprising.

As long as there are places related to scientific research in China, whether it is a small treeworm, a post bar, a BBS, or even a postgraduate tutor's complaint website, there will be various small advertisements for postgraduate recruitment.

For skilled workers who have been trained as postdoctoral fellows, they are very popular with the bosses of major research groups.

At the same time, this also shows that there is still a relatively large gap for postgraduates in China, with more demand but insufficient supply.

According to Xu Qiu's observations of the Department of Materials Science and Technology of Shanghai Comprehensive University, the number of research groups with postdoctoral fellows does not exceed 20%, perhaps only about 10%, and most research groups cannot recruit postdoctoral fellows.

Investigating the reason, Xu Qiu believes that firstly, the proportion of conversions from doctoral to postdoctoral is not high.

Most doctoral students will find that they do not have very NB scientific research capabilities during their postgraduate studies. After graduating from their doctoral degrees, they will tend to change careers, such as developing in the industry, entering companies in related fields to engage in research and development, and the like.

By the time you graduate with a Ph.D., you have to make a choice. Unlike a bachelor’s degree where you can choose to study for a master’s degree, you can choose to do a doctor’s degree after a master’s degree to “escape from choice.”

After graduating from a Ph.D., if you don’t choose to change careers immediately, but take a post-doctoral position first, and then change careers, the sunk cost will be too high.

Because they missed the school recruitment and wasted two years. At this time, their age is 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 youth.

Even the seemingly "cutting-edge" IT industry is still enjoying youth. If a programmer cannot be promoted to management at the age of 35, there is a high probability that he will be optimized or his salary will be seriously downgraded.

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, the physical function declines. Whether it is physical strength or learning ability, it is impossible to compete with young people in their early 20s.

However, the company's middle and high-level pits are limited and cannot accommodate so many "talents". Naturally, a large proportion of old employees must be optimized.

In fact, these old employees who have been optimized are not necessarily because they are not good enough, but because other people are better, and they have lost to involution.

In the future, with the aging of the population and the disappearance of the demographic dividend, for the post-00s and post-10s, the age limit of 35 may be loosened.

Because when they are 35 years old, there are not enough young post-10s and post-20s to compete with them.

At that time, 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 years old is still a real threshold.

The same is true for postdoctoral fellows who reach the age of 35. If they have insufficient scientific research ability, cannot get a teaching position and cannot enter a university, or if they enter a university and fail the "either promotion or leave" assessment, life after that will be very difficult.

The age limit is exceeded, civil servants in the system cannot enter, enterprises may not be accepted, and colleges and universities cannot enter...

Maybe you can do freelance work, set up a stall on the overpass, and put on film?

Or go back to the countryside to raise pigs scientifically and study "the influence of sunspot activity cycle on postpartum care of sows"?

Or publish a book called "Those Years I Did Scientific Research"?

Of course, if it is "Those Years I Did Scientific Research", there is a high probability that it will hit the street. It is probably better to change it to "The Stories I Had to Tell My Sisters and Sisters in the Laboratory in Those Years".

In addition to the relatively low conversion rate of PhDs to postdocs, domestic postdocs cannot be recruited, and it is also because postdocs in China are actually quite embarrassing in terms of positioning.

On the one hand, if there is no overseas study experience, it is almost impossible for a postdoctorate to find a teaching position in a university, unless he has "hard goods", such as CNS, or some top journals in the district.

Otherwise, you can only go to two or three colleges, or vocational colleges, and this means that the chances of future promotion are extremely slim.

Because the professors and students in colleges and universities are mutual achievements, no matter how NB the tutor is, it is useless if there are no students with the same NB.

Now it is all about 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 domestic postdocs to carry out their own work.

For example, the case of Wu Shengnan in the group is a special case. She mixed up a lot of articles with Xu Qiu.

And most of the domestic postdocs, after joining the group, their daily work is to help the boss write notebooks, write notebooks, write notebooks...

Even if you can do experiments, most of them are the research direction specified by the boss to realize the boss's scientific research ideas, and the autonomy is relatively small. After all, the annual salary of 200,000+ post-doctorate is not for nothing.

Of course, except if the postdoctoral fellows have their own strengths, they can sit on an equal footing with the boss.

In the scientific research circle, although seniority is also considered, but that is often something that needs to be considered when reaching the highest level. Before becoming a full professor and getting the "hat", as long as you have strength and scientific research results, you will Have the right to speak.

However, having said that, really capable doctoral graduates are basically not very good at finding post-doctorate jobs in China...

Most domestic scholars who aspire to be engaged in the scientific research industry in the future will choose to find a post-doctorate job abroad, and then after the post-doctorate graduates, they will either stay abroad to teach, or return to China to go among "thousands" or "ten thousand people". This kind of talent project is introduced back to China.

In other words, after graduating from a Ph.D., most of those who choose postdoctoral positions in China are "the weak left behind", if it is harsh to say.

As harsh as the truth may be, it is what it is.

In terms of basic science research, at this stage, China still lags far behind the beautiful country in terms of scientific research conditions and scientific research environment.

After all, what other people have accumulated in 200 years really cannot be caught up in 30 years.

Of course, the gap between the two is also shrinking at a speed visible to the naked eye, which can be seen from the fact that a large number of scholars have returned from abroad in recent years.

Perhaps one day in the future, domestic scientific research can break the blockade and achieve overtaking, so that scholars from all over the world come to make pilgrimages.

After the exhibition ended, the three of Xu Qiu returned to the hotel.

They have been in Phoenix City for two days, but the scope of activities has basically never left the area around the venue, so they plan to set aside a day to stroll around Phoenix City tomorrow, which is the 4th.

On the one hand, there is no important report to listen to tomorrow. In fact, strictly speaking, in a conference like MRS, there is no report that you must attend except for the report that you will give a speech.

On the other hand, if we wait until the 5th, when Wei Xingsi comes to Phoenix City to attend the MRS meeting after his visit from UCSB, it will be difficult to go out. Paddling is not a good choice after all.

April 4th, morning.

Xu Qiu's first stop was the Desert Botanical Garden, and the mode of travel they chose was the bus.

There is a bus station not far from the venue, where you can take a bus directly to the Desert Botanical Garden.

In terms of fares, one-way tickets are fixed at 1.5 US dollars, and you can also buy a single-day unlimited ride ticket, or "day card", which is priced at 6 US dollars.

Xu Qiu and the others purchased three daily passes with a credit card at the self-service machine next to them, and then began to wait for the bus.

The public transportation in Phoenix seems to be not very developed. The bus lines are designed to be very long, but there are very few shifts. It takes about half an hour to wait for a bus, and there are not many people using it.

At Xu Qiu's platform, apart from the three of them, there were only two other white people waiting for the bus together, and they all had MRS tags around their necks, and they seemed to have come to attend a 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 the bus with their bicycles.

Everyone got on the bus in an orderly manner, and Xu Qiu showed the ticket to the middle-aged Caucasian driver.

However, the other party didn't seem to be interested in checking the ticket, so Xu Qiu collected the ticket and found a vacant seat in the third row 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 still relatively far away.

On the way, Xu Qiu was also observing and comparing the similarities and differences between the public transportation in Phoenix City and China.

First of all, the distance between bus stops in Phoenix City is relatively short, and the number of people using them is relatively small. Therefore, if no one gets on or off the bus at the corresponding stop, the driver will not stop.

And the way to remind the bus driver if someone wants to get off is relatively simple——

Inside the bus, there is a simple small rope that runs through all parts of the car. Passengers who want to get off can pull the small rope nearby. As long as the small rope is pulled slightly, the horn for getting off the bus will sound, and other passengers can also hear it.

Some are similar to ringing the bell on domestic buses.

Secondly, the beautiful country buses provide adequate protection for the disabled and people with special needs.

The bus stopped at a platform halfway, and with the sound of an air valve, the board of the back door of the bus slowly lowered to be level with the platform outside.

Then, a middle-aged white man aged about 50+ "drives" the wheelchair onto the bus by himself, and no one else takes care of him.

When the wheelchair got on the bus, there was another "chi--", the panel of the rear door was slowly lifted, and the wheelchair drove into the compartment.

Seeing this scene, Xu Qiu was still a little shocked.

In China, if a disabled person in a wheelchair is left outside alone, no one will be at ease, let alone let them take a bus.

Moreover, although many blind passages and barrier-free passages in China have been set up, in actual use, it often happens that "the blind passage suddenly breaks while walking, or eventually leads to a dead end", "the slope of the barrier-free passage is too large, and the disabled People can't go uphill independently".

However, having said that, this is also the price that flower growers must pay for their rapid development.

In the early stage of development, blind roads and barrier-free passages, which have no obvious boosting effect on economic development, will be discarded or implemented with low-standard construction.

This world is so "fair". If you want to gain something, you will inevitably lose something.

Including flower growers have used demographic dividends, engineer dividends, and pushing up housing prices to accelerate economic development over the years, which is actually a kind of borrowing for the future.

The declining birth rate, low vitality of young people, serious involution, and slowing economic growth in society today are debt repayments in a sense.

In the end, Xu Qiu also saw a lot of "vehicles making people people" phenomenon on the road, including yesterday when he crossed the road with Han Jiaying and headed for the MRS Convention and Exhibition Center, he was also politely given up by passing vehicles.

In addition, Xu Qiu also discovered that beautiful Chinese people are not so strict in observing the red and white lights in front of the crosswalk.

When some beautiful Chinese people cross the road at a pedestrian crossing, if they see no cars around them, even if it is a red light, they will just stride over.

If this kind of behavior is placed in China, it will definitely be considered immoral. Some people may have darker thoughts: "Dare to run a red light, hit him." full responsibility".

But if you think about it from another angle, when the traffic rules of the beautiful country are formulated as "comity to pedestrians is the first principle, and traffic lights are the second principle", the appearance of this kind of behavior becomes reasonable.

In other words, red lights and white lights are just a reminder signal for pedestrians, and pedestrians on the crosswalk have absolute right of way.

At this time, there is no such thing as running a red light.

In different cultural backgrounds, or in different periods of the same cultural background, it is difficult to restrain and judge with the same set of moral standards.

For example, a domestic Nobel Prize winner once said: "Pursuing a standard of living beyond a well-off life is, in a sense, immoral."

This sentence may seem strange at first glance, but if we take "let some people get rich first, and then drive other people to get rich, and finally achieve common prosperity" as the moral benchmark, sort them according to food and clothing, well-off, and quality of life beyond the well-off, will find:

Most groups in the country are still in the stage of just getting rid of poverty and barely getting enough food and clothing. Some people who have achieved a well-off life, or those who "get rich first", do not "drive other people to become rich", but pursue their own far beyond. Living a well-off life is indeed an immoral behavior.

Because the speed of breakthroughs in modern science and technology is very slow, the fourth industrial revolution will not come soon, and the increase in the total resources of social production is very limited. It means that 10,000 people have fallen from a well-to-do life to a life of food and clothing.

Of course, this kind of moral code will greatly suppress the momentum of people's efforts and is not conducive to economic development.

Because of this, such moral codes are almost abolished now, especially in the first-tier cities, who are now advocating "996, just do it!", "What is love? I just want to make money!", "Struggle! Burn Now! Those who escaped from Beijing, Shanghai and Guangzhou, your next generation will still come back!"

...

The three arrived at the botanical garden, and each spent 22 dollars to buy a ticket to enter the garden.

The botanical garden in Phoenix is ​​quite famous. According to the information they consulted before, it is the largest desert botanical garden in the world. There are more than 4,000 species of desert plants growing inside, and more than 21,000 desert plants, of which 139 are rare and threatened. Or an endangered plant.

After visiting the site, Xu Qiu felt that it was worth the more than 100 soft sister coins. There are all kinds of colorful prickly pears, cactus and other desert-specific plants everywhere, as well as some small animals such as butterflies and hummingbirds. .

The two girls also had a lot of fun, taking pictures and group photos everywhere, and Xu Qiu became their exclusive photographer.

After visiting the Botanical Garden for more than an hour, it was almost noon, and the temperature began to rise gradually.

At this time, the outdoor temperature was very close to 40 degrees Celsius, and Wu Feifei's phone even activated a self-protection mechanism due to overheating, and it restarted automatically.

Before, the three of them spent most of their time in hotels and venues, and could turn on the air conditioner at any time. Now they ran outside for a whole morning, and finally saw the power of Phoenix City.

Therefore, they changed their itinerary and canceled 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 then returned to the hotel to lie down.

He has already adapted to the milder climate in Shanghai, but now he is still very uncomfortable in the desert climate of Phoenix.

Strolling outside is not as comfortable as staying in a hotel with air conditioning.

April 5th.

When Wei Xingsi came to Phoenix City, he first met with Xu Qiu and the others to exchange information on recent progress, mainly because the latter reported his experiences recorded during listening to reports in the past few days.

In the middle, Wei Xingsi mentioned: "A few days ago, I sent an email to the editor of "Science", and I wanted to make an appointment to meet, but the other party was inconvenient, so I didn't make an appointment, but the other party said that he was more optimistic about our work. , and are now waiting for the comments of the last few reviewers."

In the morning, Wei Xingsi took Xu Qiu and the others to meet Gong Yuanjiang, Feng Shengdong, Ronald and other acquaintances in turn. They greeted each other out of courtesy, without much communication.

For the rest of the time, Xu Qiu and the others listened to the report as usual, but with Wei Xingsi's little tail, it was not convenient for them to paddle.

It is worth mentioning that the arrival of Wei Xingsi also greatly improved Xu Qiu's food situation.

After all, it was the tutor who brought the students out for a meeting, so it must be the tutor's treat, and the place to eat is not too bad, at least not to eat donuts.

At noon, Wei Xingsi called a taxi, took Xu Qiu and the three of them to a place similar to Chinatown, and found a Sichuan restaurant for dinner.

The plaques and decorations on the outside are all in a very exaggerated Chinese style, and there are elements of the flower planter style everywhere, probably to highlight that this is a Chinese restaurant.

The owner of the shop here is also from Shanghai. When Wei Xingsi met, he would "meet fellow countrymen" with each other, communicating with each other in Shanghai dialect.

Wu Feifei is from Zhejiang Province, and Han Jiaying is from Suzhou Province. Both of them can basically understand Modu dialect. Only Xu Qiu, who is from the north, is at a loss.

However, that's not important. No matter how hot the conversation is, they are still here for dinner after all.

The business in the store is not bad, there are more than 20 tables in total, and the occupancy rate is over 70%.

About half of the guests who come here are white, and most of them come to eat in the form of families.

About half of them are of yellow race, and they seem to be basically domestic people who came to attend the MRS meeting, and many of them still wear tags issued by MRS on their necks.

None of the blacks were seen.

Wei Xingsi ordered the signature spicy chicken, boiled pork slices, mapo tofu and fish-flavored shredded pork, with four bowls of rice.

In terms of the style of the dishes, it is similar to the domestic Sichuan cuisine.

The taste is not very spicy, and it is not as delicious as the authentic Sichuan restaurant in China.

But it is also understandable that this is a beautiful country after all, and most people don’t eat spicy food. If you open a restaurant here, you need to modify it according to the tastes of the local people. If you are used to domestic Sichuan cuisine, you will naturally feel uncomfortable eating here. Habit.

After dinner, everyone returned to the MRS venue and listened to the report all afternoon.

In the evening, Wei Xingsi took Xu Qiu and the others to a relatively high-end American restaurant around the venue. This place mainly serves hamburgers, and the price is still a bit expensive.

A burger costs 38-68 US dollars, a fish and chips costs 22 US dollars, and a fruit salad costs 28 US dollars.

In the end, four people ordered four burgers, one fish and chips, one fruit salad and four beers.

When it came to drinks, Xu Qiu and Han Jiaying, who looked relatively small, had their passports checked again.

When they were being investigated, Wu Feifei next to her had a complicated expression...probably a little envious.

The burgers in this store are very large, with a diameter of about 20 cm and a height of about 30 cm.

Because the hamburger is too big to stand on its own, the store used an iron pick 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 layer of very thick beef patties, then another layer of cheese, a layer of very thick beef patties , a layer of cheese, a layer of onion, tomato and sauce and a layer of bread.

With such a big hamburger, Xu Qiu estimated that even if O'Neill came over, opened his mouth wide and dislocated his jaw, he would not be able to swallow it whole.

The taste of the hamburger is also very good, at least the domestic Kaifeng dishes are overwhelmed, after all, the price is there.

As for the beer, it is a locally produced dark beer, and the taste is quite satisfactory. The taste of the wine is not too strong, and it is slightly bitter.

April 6th.

Xu Qiu got up early in the morning, put on formal attire, checked the PPT for the speech again at the hotel, and then went to the MRS venue with Wei Xingsi, Han Jiaying, and Wu Feifei.

The report officially started at 8:00, but at 7:30, people had already entered the venue one after another.

Among them is the chairman of today's meeting, Su Haibo, a Chinese researcher from MIT, about 50+, male, slightly Mediterranean.

When Xu Qiu was reading high-end literature in the field of organic photovoltaics, including the major sub-journals of "Nature", he often saw Su Haibo's name, and knew that he was an ancient leader in the field of organic photovoltaics.

Why is it said that it is an ancient boss? It is because Xu Qiu is almost the only one in the new generation of bosses. In addition, Wei Xingsi has been honored by him, and now he has entered the ranks of the boss.

Xu Qiu can be said to rely on his own strength to drive the entire team to take the field of organic photovoltaics to a big step.

At 7:55, Xu Qiu stepped onto the podium.

Su Haibo introduced with great enthusiasm: "Today's first report is Xu Qiu from Shanghai University of Technology. His supervisor 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.

Standing on the podium, Xu Qiu looked at the dark crowd. Some of them were familiar faces in China, but most of them were unfamiliar scholars from all over the world.

However, he didn't feel too nervous. His scientific research experience over the years can be said to have greatly tempered his ability to speak on the spot.

Xu Qiu still remembers that when he was in high school, his legs would shake when he gave a lecture on a topic in the class, but now he can even give a report at a top international academic conference such as MRS, and he feels that he can handle it with ease.

Taking a deep breath, Xu Qiu began to talk about the work he led this year:

"In the first stage, the origin of ITIC, based on the IDT-ICIN material, we modified the conjugated main chain of IDT, changed it to IDTT, obtained IDTT-ICIN, and named it ITIC..."

"At this time, the field of non-fullerene organic photovoltaics has entered the stage of 10% efficiency."

"In the second stage, based on the ITIC receptor, four optimization paths are derived:

"The first one is to modify the A unit, that is, the end group of ICIN, to obtain several acceptor materials represented by IT-4F, IT-M, and IT-4Cl.

"The second is to modify the side chain of the central D unit to obtain materials such as IDIC and m-ITIC.

"Third, modify the main chain of the central D unit to obtain FNIC, 4TIC, IHIC and other materials.

"Article 4, imitate the IDTBR structure, design the structure of AπDπA, and obtain the IEICO series materials.

"At the same time, the donor materials have also been designed, including H series and J series donor materials...

"At this time, the field of non-fullerene organic photovoltaics has entered the stage of 12% efficiency, which is equal to that of traditional fullerene systems."

When he was talking about this, Xu Qiu noticed that Wei Xingsi in the audience suddenly stood up after looking at his phone, with an extremely excited expression on his face.

However, Teacher Wei seemed to realize that this was the meeting place, and quickly sat down again, apologizing to the other scholars around.

Although Xu Qiu was somewhat puzzled by Wei Xingsi's actions, he did not interrupt his speech and continued to report:

"In the third stage, on the one hand, we combined the non-fullerene acceptor system with various concepts, including translucent, scrape-coated, flexible, and ternary blend devices, paving the way for future commercial applications; on the other hand On the one 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 field of organic photovoltaics has entered the stage of 13.5% efficiency, breaking the efficiency world record at that time."

Finally, at the end of the speech, Xu Qiu briefly mentioned the results of the recent experimental work, but did not put the specific details on the PPT. After all, the article has not been published, so it is not suitable to speak at this kind of conference:

"In the fourth stage, through the preparation of stacked devices and the development of Y series acceptor materials, we have sprinted the efficiency of the organic photovoltaic field to more than 17% and 18%!"

When "18%" was uttered by Xu Qiu, the researchers in the audience immediately started whispering, as if they were confirming whether they had heard it wrong.

It should be known that among the reported results, the highest device efficiency in the field of organic photovoltaics is only 14%, which is the stacked device published in "Nature Optoelectronics".

However, some people did not seem surprised, such as Su Haibo on the stage, he applauded and said: "The organic photovoltaic field can achieve an efficiency of 18%. It is a hero born out of a young man. The speech is also very good. What do you think?" Questions to ask?"

Wei Xingsi immediately raised his hand, and said excitedly: "Xu Qiu, the comments on the "Science" article have come back, and the editor's suggestion is to accept it directly! Please share the PPT you made earlier with everyone!"

As soon as this remark came out, the other researchers in the audience were talking and whispering again:

"There hasn't been an orthodox CNS experimental article published in the field of organic photovoltaics for many years. I didn't expect it to be won by this young man on stage."

"Moreover, in a crushing situation, the original efficiency record of 14% was directly broken to 17% in one fell swoop."

"Not only that, but the binary Y-series receptor material he just mentioned corresponds to an efficiency of 18%, and it is also very likely to get another CNS."

Some bosses of research groups work in multiple fields at the same time. Seeing that the field of organic photovoltaics is expected to make a breakthrough and become a hot field, they also wondered in their hearts: "Should we intensify research efforts in the field of organic photovoltaics?"

Xu Qiu didn't know what other people were thinking, so he tilted 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 a gesture of acceptance: "I am the reviewer of your article in "Science". Your writing is very good."

"Thank you." Xu Qiu thanked, then found the PPT of his layered work, gave a speech in public, and once again received warm applause from the scholars in the audience.

Afterwards, under the organization of Chen Haibo, Xu Qiu communicated with other researchers in the audience.

As a result, if you don't communicate, you don't know, and when you communicate, you will be shocked.

Xu Qiu didn't expect that in this field, there would be a crowd of bigwigs in the audience. Besides Chen Haibo, there were two other scholars who were also reviewers for 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, the giant who previously reported 14% efficiency stacked 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 a postgraduate study with them. Naturally, Xu Qiu did not agree and politely declined. Forrest was not annoyed, saying that if he had any ideas about this in the future, he would welcome them at any time.

After finally dealing with the enthusiastic audience, Xu Qiu returned to the stage.

Then, he accepted some compliments from Wei Xingsi, Han Jiaying and Wu Feifei.

It wasn't until the next report began that everyone's attention was diverted.

Xu Qiu adjusted his sitting posture, entered the system interface, and his consciousness was pulled into the system space in an instant.

The system space seems to have returned to the original chaotic state, surrounded by colorful black.

The system's prompt tone also came as scheduled:

It is detected that the host has published an article in any journal of "Nature", "Science" and "Cell" as the first author/first corresponding author. The advanced task has been completed, and the authority level is +1.

It is detected that the current permission level is level 9, which has reached the highest permission level.

"Scientific Research Assistance System" is being unbound...

"Scientific Research Advanced System" is being bound...

After carefully understanding the functions of the new system, Xu Qiu frowned and exited the system space.

Han Jiaying next to her seemed to have noticed something, and asked in a low voice, "Brother, what's the matter?"

Xu Qiu smiled mysteriously: "It's nothing."

‘I always feel that there are many secrets in my senior brother. '

Although Han Jiaying had doubts in her heart, she didn't pursue it.

Facts have proved that women's sixth sense is quite accurate.

On April 6, 2017, later generations called this day the beginning of the birth of a generation of legends.
