I Have a Research Support System

Xu Qiu's other four roommates in rooms B and C of 16-402 in the North District also moved in.

Everyone got together and chatted, and found that four of them were direct doctoral students and two were masters of science.

There are five direct Ph.D. students in the Department of Materials this year, four boys are in suite 16-402, and one is a girl. The dormitory building is not in Building 16.

Among them, Xu Qiu and Sun Yifan in room A are direct Ph.D. students of the school’s Department of Materials Science and Technology. Room B is also a direct Ph.D. student of the school’s department. Come on Master of Science.

Although Xu Qiu and the other four people in rooms B and C are also roommates, they basically don't meet face to face. The relationship is more similar to the dormitory next door when they were undergraduates, and even a little colder.

It's not that they will be cold-faced when they meet each other, and they will greet each other politely when they meet face-to-face, it's just that everyone has their own rhythm of life and work, and they don't take the initiative to contact each other.

These days, what Xu Qiu focused on was his roommate, Sun Yifan, who lived in the same room. After all, he was forced to spend one-third of his time with his roommate every day.

If you encounter a strange thing, such as teeth grinding at night, snoring, sleepwalking... don't mention the taste.

Fortunately, after a few days of contact and communication, Xu Qiu found that Sun Yifan was relatively easy to get along with, and he didn't have any special nighttime behaviors.

Sun Yifan’s height is 185+, tall and big, he likes to be clean, and the clothes are soaked by himself and washed by hand. Like Xu Qiu, he is lazy. Except for underwear, other clothes are directly thrown downstairs for 2 yuan a time in the communal washing machine.

In addition, Xu Qiu learned that Sun Yifan was from Lu Province during the chat.

Lu Province gave Xu Qiu the impression that there are many top students. When he entered the "Mathematical Analysis" course in his freshman year, there was a mid-term, final exam, and ordinary quiz with a perfect score of 100. The top students are from Lu Province, which can be regarded as real. "Others can get 100 points in the test because the full score is 100 points."

At that time, Sun Yifan took the route of self-enrollment to enter Shanghai Magic City Comprehensive University. His college entrance examination score was 650 points, and then his score was reduced by 50 points to be admitted. That year, the score line of Shanghai Magic Capital Comprehensive University in Lu Province was 682 points.

Generally, there are not many cases of direct admission for self-enrollment. Most of them are admitted with lower scores based on the scores of written tests and interviews. Only for a single school, the limitations are relatively large.

However, for students, there is no room for choice, some drop is not bad.

Moreover, self-enrollment is the right way, which is much better than heresy ways such as college entrance examination immigration.

After all, for a large college entrance examination province like Lu Province, candidates must not miss every opportunity. If you only want to take the hard test, you need to score 682 points out of 750 points, which is too difficult.

But having said that, Magic City Comprehensive University has preferential treatment for students admitted through forced entrance examinations, that is, students whose grades are higher than the admission score. When choosing a major, you will only look at the grade-up score, that is, the naked score of the college entrance examination.

In the same way, it is generally difficult for recommended students to choose a good major.

The most famous one is the Department of Archeology of Qingbei University.

When Xu Qiu was in high school, a classmate whose grades were always in the top three of his grades went there for archaeology. I don't know how he is doing now, whether he has dug up cultural relics for the country, or changed his major midway.

Under normal circumstances, as long as the student type is not a national defense student, an orientation student, or a Weipei student, you can change majors, but sometimes there will be a condition of "not changing majors" when recommending. At this time, you have to carefully consider whether you want to go to archaeology .

On Sunday morning, the school registration started, the campus was crowded with people, and there was a banner on the school gate "Welcome new students of grade xx".

Xu Qiu re-entered the school and became a newcomer again. He wandered around the campus casually, admiring the "scenery" everywhere in the campus.

Shanghai Jiaotong University is a comprehensive university with no obvious preference for arts and sciences. It may be slightly biased towards arts and sciences. Therefore, the ratio of male to female is relatively normal, close to 1:1. The quality of freshmen is not bad. It is better than Shanghai Jiaotong University. No, it is said that there is "a couple and three pairs of bases"...

If you are an old student, registration at the beginning of the semester is relatively simple. You can go directly to the Academic Affairs Office of each department to punch in and stamp your registration.

For the convenience of being found, the registration location for freshmen is set directly on the campus.

Among them, the registration point for undergraduates is quite eye-catching. Entering from the main entrance of Shanghai Comprehensive University, there are a number of freshman reporting booths on both sides of the "Mao Statue". "Natural Science Experimental Class" and so on.

Counselors either alone or with assistants receive new students in front of the booth, take pictures of the new students, and distribute materials. There are various slogans hanging on the trees behind the booth.

There is a chicken soup style: "Use the vitality of youth to transform into a gorgeous rainbow, and use the enthusiasm of life to compose a vivid melody."

There is a funny style: "Little goblins, you are finally here!"

There's the terse version: "This is a welcome banner."

There are also those who directly take the school motto: "Knowledgeful and dedicated, ask earnestly and think closely."

After wandering around the campus, Xu Qiu went to the registration point for graduate students, the gymnasium in the North District, where the basketball court had been transformed into a place for welcoming freshmen.

Xu Qiu found the booth of the Materials Department, and the person in charge of receiving it was the counselor, Bao Wei.

Bao Wei was in his early thirties. When Xu Qiu saw the real person, he found that he looked a bit thick-browed and big-eyed, like Liu Bei. Compared with the pictures that looked polite on the official website of the Department of Material Science and Technology, he was completely different. two people. Sure enough, the photos should not be trusted. These days, it's not just the girls who will cheat on this skill.

"Hello counselor, I'm here to collect the materials. I'm Xu Qiu, and my student number is..."

"Hello, Xu Qiu, welcome to the family of the Department of Materials Science."

Bao Wei was quite enthusiastic. He greeted every new student with great energy, and then distributed a lot of materials to each of them.

Xu Qiu was very thankful that he brought a schoolbag on his back, otherwise it would be really inconvenient to carry these materials empty-handed.

Among them, the materials include a one-card card without a printed photo, a blank student ID card, a training plan, a freshman admission handbook, a campus map, a freshman personal information form, a medical examination form, a medical examination schedule, a letter of commitment to academic integrity, etc...

The avatar of the card is blank, but the major, name, and student number have been printed on it, access control, canteen consumption and other functions have been activated, and there is still 100 yuan in it. Of course, this money is not sent by the school, but an advance payment Yes, it needs to be handed over to the counselor after school starts.

For the student ID card, you need to fill in the information, paste a recent bareheaded one-inch photo, and then submit it uniformly with the stamp of the school.

Most other materials need to be filled out manually.

Among them, the more special one is the Academic Integrity Pledge, which Xu Qiu had never seen when he was an undergraduate.

The workmanship of this letter of commitment is not bad. It is printed in color on hard cardboard and is in duplicate. There is also a Chinese and English bilingual copy on the front and back. After reading it carefully, it probably means: "I promise: During my postgraduate study, I will not I will commit academic misconduct, academic misconduct, and conduct scientific research with integrity..." Below is the signature of the promiser.

At first glance, it kind of looks like the Terms of Use...

Xu Qiu infers that the school and the department are exempt from liability. As long as the student signs, it means that the school and the department have informed the student of this matter, and the student has fully understood the content of the commitment letter and made a promise, then In the future, the problems of academic inappropriateness and academic misconduct are the problems of the students themselves, and have nothing to do with the school or the department.

Of course, if something really happened, the school and the department would definitely not be able to completely shake off the blame, but with the letter of commitment, they could more or less shake off part of the blame.

Monday group meeting.

Wu Feifei began to write a review of "two-dimensional perovskite".

The work handover between Duan Yun and Wu Feifei was basically completed, and they began to study "cobalt nanowire-doped PVDF thermoelectric materials" together.

In fact, although Duan Yun did not publish many articles, he actually did a lot of work, because the preparation and testing of thermoelectric materials are relatively easy. The more difficult thing is the construction of test equipment. There is no special instrument in China. The company and other research groups working on thermoelectric materials also set up their own equipment, which is a task from 0 to 1.

Sun Wo reported anxiously: "Last week, I prepared...a tin-based two-dimensional perovskite solution and spin-coated it. This time, the coated film was much smoother, but the performance of the device was poor, with a maximum of only 0.01% , XRD test results show that the crystallinity of the two-dimensional perovskite film is poor, and further optimization is needed..."

Wei Xingsi rubbed his head and said helplessly, "Don't talk about the efficiency of 0.01%, just say that the device doesn't work and it's over..."

After that, Wei Xingsi looked at the projection screen, tapped his fingers on the table, Erlang raised his legs and shook, and after more than ten seconds, he said: "Try these systems again, if they don't work, start with the lead-tin mixed system." To start, don’t do pure tin, if you want to publish your work, you must at least be efficient.”

Sun Wo murmured back, "Okay."

"Tian Qing, tell me." Wei Xingsi waved his hand and said.

Tian Qing got up, fiddled with the laser pointer, and narrated without haste:

"Last week, the CEILV and TOF characterization based on the J2:IDIC-4F system were tested..."

"The mobility data obtained by the two test methods are close. Among them, the electron mobility obtained by the CELIV method is 1.46 times ten negative cubic centimeters squared per volt-second, and the hole mobility is...

"The ratio of electron and hole mobility is close to 1, which is beneficial to suppress charge recombination and improve the fill factor of the device..."

"This week I plan to test the data of exciton binding energy and exciton diffusion distance of other ITIC series acceptor materials to complete the database."

"Well, you did a good job," Wei Xingsi nodded in satisfaction after listening. "At that time, put multiple systems together, sort out the data of exciton binding energy and exciton diffusion distance, and make an article."

Chen Wanqing continued the two tasks at hand, the IEICO-4F work, the article was about to be written, but due to the lack of light source data, it could not submit for the time being.

There are two light source tests this time, GIWAXS and R-SoXS, both scheduled for September 14th, which is next Tuesday.

Xu Qiu’s articles on the Liver IDIC system were basically all the rest of last week. Except for the light source data and NIM third-party detection data, other data are complete, and the progress of the article has reached about 80%.

Han Jiaying mainly helped Xu Qiu perform the basic characterization of the IDIC-4F system last week.

At the same time, she is also writing articles on her own J2 and J3 donor material systems. She was originally assigned an ITIC-Th system before, and she was a little busy.

In the end, the school girl had to put the J2 material as the first priority. After all, the donor material used in the IDIC-4F system is J2, and the J2 material needs to be published first, and the writing progress of the article has reached about 80%.

Wu Shengnan also has many systems in his hands, including the six-in-one system, m-ITIC, and IDIC-M. At present, the characterization of the six-in-one system is basically completed, and the article is being written, and the characterization test of the m-ITIC system is planned to start next week.

Mo Wenlin was not here today. She returned to Kainan University in Jincheng to register for freshmen and go through various procedures for exchange students. By the way, Xu Qiu gave her some samples, including J2:IDIC-4F and other systems, and made an appointment NIM for third-party testing.

PS: There are also three changes in 4D today, and the third change is at 4:00 pm.
