PS2: American chemist and former Nobel laureate in chemistry Richard Hecker died on October 10 in Manila, Philippines, at the age of 84 due to multiple organ failure. According to Heck's personal nurse, Heck was rushed to a private hospital with severe vomiting but was turned away because he could not afford to pay for his medicine. This old man is the ancestor of the organic world, when he carried out research alone in a company, in 1968 as the sole author (yes, the only author) published seven JACS in a row to create a new field in one fell swoop, so far countless chemical dogs in the world are relying on his achievements to eat - Nobel laureate, a generation of gods who promote the progress of human civilization, but in his old age is so bleak!

I would like to use this chapter to commemorate my former youth and see off my grandfather - I wish him 72 PhDs in heaven to carry bricks for him, and do whatever he wants......

"Yucheng, you're okay tonight, right? After all, this thing won't end until twelve o'clock in the middle of the night..."

"Ah, it's okay little sister - I originally wanted to spend the night, and I happened to stay in the laboratory, so I didn't have to go to the building to occupy a seat..."

"Oh, that's good—then Yucheng, I'll take care of the instrument!

"Okay—goodbye, senior sister!"

After saying goodbye to Zhang Linan's senior sister in the organic laboratory, Jiang Yucheng continued to turn his gaze to the Surface in front of him—and the paper notebook in front of the screen.

Half a year ago, at the invitation of Mr. Deng, Jiang Yucheng signed up with him to participate in the university's college student innovation experiment program, referred to as "Daiso". The official definition is as follows: The National College Students' Innovative Experimental Program is a project in which undergraduate students or innovative teams independently select topics for design, independently organize and implement, analyze and process information, and write summary reports under the guidance of their supervisors, so as to cultivate students' interest and ability to raise questions, analyze and solve problems.

In practice, for the students of the Department of Chemistry of the Faculty of Science, except for a very small number of top students, the so-called "independent topic selection and design Blablabla····" Things like that, they're just things that exist on paper. The essence of this "Daiiso" is actually just a cover for the mentor to get research funds... From topic selection and design to writing a summary, a lot of work is done by tutors, and Jiang Yucheng and other students can basically only watch from the sidelines.

Generally speaking, the real value of "Daiso " lies in the fact that students who are interested in scientific research can take this opportunity to have a good relationship with their mentors on the one hand - in this way, whether they are doing graduation projects or graduate school entrance examinations in the future, they will take a big step forward than others, and on the other hand, they can enter the real research laboratory in advance through this platform to do experiments and learn various experimental skills - these things cannot be learned in basic laboratory courses.

However, Jiang Yucheng actually has no feeling for scientific research or anything - although the Department of Chemistry is considered a non-mainstream department in the National People's Congress, non-mainstream does not mean that the results are poor. In fact, on the contrary, the chemistry department has a large number of top students, and almost all of the top 50% of the class have participated in minors and daiso. Jiang Yucheng participated in this purely out of following the trend - but now, as an undergraduate student participating in Daiso, he really enjoys a "privilege"-

The dormitories of Renmin University are all lights out at 11 o'clock, and there are only a few classrooms in Qiushi Building where you can spend all night in the study room, which is full every night - not only crowded with students from our own school, but also many students from neighboring schools. Daiso participants can be on duty directly in the lab – in other words, Jiang Yucheng can borrow a desk in the lab to study on his own...... Although this "privilege" is not very useful to him next to the school, but when he wants to calm his bored inner peace like now, the laboratory has become a good place to go.

Jiang's mentor, Boss Xu, chose the topic of his project: the Heck-like coupling reaction between allyl amine and ArCOOH catalyzed by palladium catalyst - what this lengthy name means, Jiang Yucheng, who has just entered his second year, obviously can't understand. However, this has nothing to do with Jiang Yucheng now......

For Jiang Yucheng, he didn't have to do anything at the beginning, as long as he did his own thing, waited until twelve o'clock in the middle of the night, then turned off the electromagnetic stirrer, took out the mixed liquid, according to the old rules, confirmed the plate, and then stroked the tube, ah no, the product was separated through the column, the eluent was evaporated, and finally the product was put into the NMR tube, waiting for the NMR tomorrow. Because it takes a long time to cross the pillar, the senior sister explained that she didn't have to pass the product tonight, and if she was in a hurry to leave, she just had to build the pillar.

The laboratory at night is silent, except for the rustle of the tip of the pen against the paper, except for the faint sound of the electromagnetic stirrer. Despite the open windows for ventilation, the air inevitably fills the air with a faint smell of Acetone - this is the smell that Jiang Yucheng is most familiar with, which only belongs to the organic laboratory...

For others, the smell can be dizzying – after all, most organic solvents are volatile and have a faint toxicity. However, for Jiang Yucheng, the taste is so reassuring - in this pleasant, faint aroma, Jiang Yucheng seems to have just passed through the self-generated power generation for a while, and has entered a complete sage mode.

Although he just obeyed his family's arrangement during the college entrance examination, and chose a major according to the principle of "choosing a school for undergraduates", plus he had a good score in chemistry in high school, he didn't have any feelings about chemistry and scientific research itself -- but now, Jiang Yucheng feels that doing organic chemistry seems to be good! Compared with these wonderful chemical changes, how insignificant is the argument in the online literature Jianghu? Nana wants to find the right hand king, then let her find it!!If you don't want to update, then don't update! I don't lack this income - as for my sister, since she can have a better future and better development, she should obviously be happy as an elder brother!

"Multiplication of matrix A and matrix B transpose..."

Jiang Yucheng, who threw away all his troubles and had no distractions, his learning efficiency improved a lot for a while - he passed all the way, and the linear algebra examples and exercises that originally seemed difficult and obscure were all cut down by him for a while. Jiang Yucheng not only finished his homework, but also brushed all the exercises in the first two chapters he had learned so far...

"Oh!! it's done..."

At 11:45 p.m., Jiang Yucheng, who had finally completed all the tasks, got up from his chair and stretched his waist vigorously - in the current laboratory, only the "hum" of the electromagnetic stirrer was left. After setting up the chromatography column, he quietly looked at the magnet in the flask, which was constantly rotating under the electromagnetic force, and waited for the moment when the reaction was completed.

"Africa's agriculture is underdeveloped..." Ten minutes later, the phone alarm went off – twelve o'clock in the morning. I followed the protocol of laboratory operation, fully armed with a white coat, rubber gloves, mask and protective glasses, and then carefully dropped the reaction solution into the chromatography column that had already been erected, injected the eluent prepared with petroleum ether and ethyl acetate, and then unscrewed the piston and waited for the mixture to drip down on its own.

"Ahh!!!!~~~~~h

At this time, the previous tranquility was completely shattered - although the volume was not loud, Jiang Yucheng could still hear it clearly: this was a girl's scream.

"What's going on?!"

Jiang Yucheng suddenly became alert, turned off the piston, and trotted to the window facing the direction of the sound source, the dark side of the laboratory.

"Help... Woo..."

Lao Xu's organic laboratory is located on the second floor of the science and engineering building—from the shady window, Jiang Yucheng can clearly see traces of dragging and struggling on the ground, as well as a mobile phone and a very girlish shoulder bag. But nothing else was to be seen anymore - for no other reason, only this street lamp was lit on the side of the road downstairs.

"I'm going to be researched!!!This TMD is going to be researched!"

Jiang Yucheng suddenly understood what was happening below - when he first entered the school, his sophomores and juniors once told him that the "four monsters of the people's congress" in the early years had been circulated since the previous generation: a spoonful of green paint at the bottom of the pool, the boys were only 1.7 meters, the elevator was installed in the canteen on the third floor, and there was no need for credit grades for the research institute (Note 1). The first three monsters don't press the table, and the fourth blame "Baoyan doesn't use credit grades" is the so-called "Baoyan Road" that makes some girls tremble and makes other girls eager to try...

It's not a good word, in fact, it's full of irony.

In many colleges and universities, especially those with relatively large areas, there are one or two remote places far away from the center of the school, and some bad things will happen every once in a while, the most typical is the strong X and other events.

For those victims, the university will give different levels of compensation depending on the severity of the situation – the most common is Baoyan. Over time, this high-risk area of accidents was named "Baoyan Road" by students. The road near the main building of the School of Science, where Jiang Yucheng is located, is one of the notorious "Baoyan Road" in Northeast China because of its remote location and the fact that the surrounding street lamps are often smashed.

Note 1: The full definition of the three monsters

The first refers to an artificial pond on the campus of the National People's University, which is about 10 meters long and 7 meters wide, in an irregular oval shape. Slightly like a drop of water, the middle vertical strange stone, the front is the red inscription "a spoonful of pool", the back of the couplet: "swallow and spit three rivers of water, a spoonful of pond pleasantly". For a while, the stones at the bottom of the pool were cleared and painted with green paint... Of course, I can't see it now.

Article 2··· I won't say anything about it - this was the case in the early years, and now the average height of the boys in this school is almost the same as in the whole country. By the way, there is also a version of "Mingde Building (the main building of the school) has fallen off the wall"

The third refers to the canteen in the central district, because the third floor is a "high-end" hotel open to the public, so a sightseeing elevator was specially built... My father used to have a guest there, and in all fairness, the value for money there was still very good.
