Rebirth of the God-level Xueba

Although China's university education in the 1980s was purely elite education, it was limited to financial resources and accumulation. In terms of experimentation and practice, it did not necessarily ensure that ordinary college students learned more than later generations of college students.

But on the other hand, the postgraduates and key majors of prestigious universities at this time are pure elite education. For example, schools like Tsinghua University, Peking University, University of Science and Technology of China, have arranged for superstars to directly lead undergraduate classes. It is also very common for academicians of the Academy of Engineering to choose two students as assistants. This kind of training is rare after more than ten years, and the so-called postdoctoral fellows are not treated quite well.

In the early 1980s, the frequent emergence of outstanding students among college students had a great relationship with the education system at that time. Whether it is academics, management, or an official, experience is an extremely important asset. College students 30 years later may have never touched those top-level instruments until their senior year, but in the 1980s, there were many freshmen, freshmen and sophomores who could get such opportunities.

Nowadays, there are very few teachers and few students. They are not professors who are as good as heaven, and they dare not say that they can have a few tutors and teaching assistants to help them work. In 1982, the recruitment of doctoral students had not yet started, and graduate students were recruited directly without undergraduate training. Therefore, many students who seem to be very spiritual, once they are lucky, may enter the laboratory of a certain genius and participate in some some crucial experiments.

Students of later generations may have to wait 20 years for a similar opportunity.

If Jiang De graduated from Hedong University with a master's degree, Yang Rui would not repeat the experiment on the spot. Extracting coenzyme q10 by saponification is not a great invention, but it also represents a huge amount of foreign exchange. Yang Rui urgently needs this pot of gold and is unwilling to take this risk. In comparison, a report cannot be compared at all, even if Principal Zhao is unhappy, it is useless.

However, since Jiang De is a chemistry undergraduate at Hedong University, it is impossible for him to know all the experimental procedures of the biology major.

Given the degree of affluence of the university at this time, it is estimated that it cannot support students to do experiments across different departments. At least, ordinary students cannot get this kind of treatment.

"The experiment may take a long time." Yang Rui didn't plan to perform the experiment, so he was going to make the first move at this time, and let it be delayed.

He pulled out the stock suspension, the preliminary extract of pig organs, from the freezer. This thing needs to be beaten with a tissue blender. The principle is similar to that of a juicer. It consumes a lot of electricity and causes a lot of pollution in operation. Yang Rui thought about it for a while, and decided to use the primary raw materials from the Xibao Meat Factory first.

Looking at the label on the test tube, Yang Rui handed it to Jiang De and said, "You know how to use an ultraviolet spectrophotometer, let's measure the content of coenzyme Q10 in the raw materials first."

Jiang De offered to show it, and said that after reading Yang Rui's article, he naturally knew how to measure the content of coenzyme Q10 by ultraviolet spectrophotometer.

but,

Yang Rui was able to write a paper on it that day, explaining that the steps are naturally not simple, and the petroleum ether used in the steps has a smell of kerosene, which is very unpleasant.

Jiang De glanced at the test tube in embarrassment, and said, "I think the test tube is well sealed. Otherwise, use the logo on it to make preliminary data?"

Yang Rui smiled: "Everyone is watching, let's be strict."

He usually directly uses the label on the test tube. Although the visceral biochemical workshop of the Xibao Meat Joint Factory is backward, it is still somewhat basic, and there will not be an order of magnitude error. As far as Yang Rui's experiment is concerned, he doesn't need to be accurate to less than 1 percentage point. Of course, he occasionally checks the content of suspended solids in the freezer, and most of these tasks are actually handed over to Wei Zhenxue.

The latter is still a member of the Coal Research Institute, so it is not easy to show up today.

Jiang De felt that something was wrong, took the test tube, thought for a long time, and said: "Otherwise, you should come, I have never used the equipment in this laboratory, I will continue to be your experimental assistant."

"Well, let's go step by step, and you should also remember that we have to test the content of other products later." Yang Rui wrote a paper on increasing production, so what if the content is not measured.

Jiang De couldn't say anything to refute, so he nodded silently.

He originally thought that he was several years older than Yang Rui, so he should be easily manipulated in his hands, but he didn't expect Yang Rui to burst into a powerful aura after entering the laboratory.

To say that there are a lot of instruments, in Jiang De's eyes, there are at most a dazzling array of things. After all, except for the ultraviolet spectrophotometer and mechanical analytical balance, the instruments are relatively rough. However, Yang Rui's attitude of preparing experiments and assigning work reminded Jiang De of his college days.

When you meet an experimental instructor whose academic level and experimental familiarity are higher than your own, what can you do except obediently obey orders?

Yang Rui's movements were slow and standard. It took him almost half an hour to complete half of the steps.

At this time, the novelty of everyone has long passed, watching Yang Rui shake the bottle, I just feel very bored.

A cadre couldn't help asking: "Student Yang, how long will it take?"

"It must take several hours." Yang Rui said without looking back, wearing a white coat.

The cadre hesitated and said, "Or, let's visit other facilities of the school first, and then check the results when we come back? Student Yang, can we finish it in 3 hours?"

"At least 6 hours." Yang Rui wished they could leave quickly. After 6 hours, these cadres who have eaten dinner and drunk wine will be fine if they can open their eyes to see people, and what kind of experiments are they watching.

Without waiting for others to comment, Ding Yaqin frowned and said with a smile: "It doesn't matter six hours, just give me a cup of tea, you go to visit first."

Where can I visit a school as big as a palm for six hours?

Seeing that Ding Yaqin was going to stay, Jiang De was suddenly full of motivation, and seemed to feel that the connection between himself and the beauties from Beijing had become closer.

Yang Rui frowned secretly. Anyone who majors in biology has to do three things, set fires, prevent viruses, and prevent journalists.

Because the biology major is really special. Those who engage in physics make atomic bombs, contact aliens, and even make even more terrifying particle accelerators. I pretend that I am not afraid of the destruction of the earth. The media occasionally makes fun of it. Ordinary people don’t care at all. Nuclear Power Plant.

It’s different for those who do biology. What a great achievement cloning is, and as a result, people criticize it every day. Some Adou who can’t get a score of 50 in high school biology can talk about human embryos and cell nuclei... If there is no media to fuel the flames, where would it be? There are these crap.

The human test-tube baby that began in 1978 has also been controversial. Countless people waved the ethical benchmark and attacked wantonly with the cooperation of the media. The researchers did not win the Nobel Prize in Medicine until 2010. Before that, there were already 5 million couples got consummated families.

Yang Rui doubts that Ding Yaqin's fans will turn black.

Do you need to stare at yourself and do 6 hours of experiments to reprint a newsletter? It has been done for 3 hours now, which adds up to 9 hours, which is definitely uncomfortable and unnecessary in a small and difficult to ventilate ordinary laboratory.

All the photos that should be taken have been taken, and the hundreds of words are reproduced in the newsletter, and there is no need to modify anything.

Could it be that he came from a long distance and was unwilling?

Writing a black article is definitely more targeted than writing a red article, and it is easier to cause a sensation.

If it were a prudent reporter in her forties or fifties, Yang Rui would probably think of the best, but seeing Ding Yaqin in her early 20s with a sense of superiority, she is not sure.

Perhaps, major national newspapers will not easily publish black articles, but who can say clearly about this kind of thing.

Reports such as "falsified papers" and "gunmen writing papers" may be able to destroy one's qualifications for the college entrance examination-the strength of Chinese journalists in taking stories out of context cannot be underestimated. It will be even more difficult to wash away the stigma in the future.

"Section Chief Jiang, please measure the Q10 content of the intermediate, or use ultraviolet spectrophotometry." Yang Rui ordered, and continued his work, as if he really used Jiang De as an experimental assistant.

No matter what Ding Yaqin thinks, smoke it with petroleum ether first.

Kerosene bacon still seems to be in line with Chinese recipes.

Ding Yaqin covered her nose with her hands, but she didn't intend to quit.

Constant extraction testing, extraction testing, and finally the real mid-stage step.

Yang Rui thought about it for a while, said to wait a moment, walked out of the laboratory, first found He Cheng and Cao Baoming, then found Liu Shan, and gave orders to each of them before returning uneasy.

Cao Baoming is tall and suitable for work that blocks sight. He Cheng is familiar with experiments and knows which steps are more critical. As a girl, Liu Shan is not particularly difficult to talk to Ding Yaqin.

Actually, the best choice is to let Jiang De and Ding Yaqin chat. However, due to the atmosphere, Jiang De's lust and courage are quite insufficient.

In the whole laboratory, only he knew the key points, Yang Rui secretly dismantled the experimental steps.

When mixing ethane, methyl isobutyl ketone, butanol, ethyl acetate and other compound solvents, Yang Rui first mixes half or even one third, and then completes the final mix under the cover of the instrument, hands and classmates .

The main theoretical basis for Yang Rui's saponification method to extract coenzyme q10 is that coenzyme q in water is alkali-resistant, and at the same time, non-saponifiable phospholipids containing coenzyme q can be obtained with high yields by solvent extraction.

Therefore, the crux of the problem is to find out a suitable solvent that is insoluble in water.

This is a simple yet tedious experiment.

If you don't know the answer, it's almost a matter of trial and error. That is, one test at a time. How about 50% sodium hydroxide? Is it better to heat 50% sodium hydroxide to 100 degrees, or to 80 degrees? How about a water bath for 3 hours? How about 30 minutes?

When the number of parameters reaches a certain number, the trial-and-error method is absolutely life-threatening for students, and there are those who have done hundreds or even thousands of experiments-the tutor in charge of the project will not do this kind of work, so he will only give it to student. To be honest, many domestic research results come from graduate students with a monthly salary of 800 yuan and doctoral students with a monthly salary of 1,200 yuan. Cheap scientific and technological labor is also a sufficient reason for the transfer of many international scientific research institutions, just like the transfer of manufacturing industries back then.

Yang Rui's advantage is that he has well-formed papers, so he doesn't need cheap experimental assistants, he can just use the answers that others have tried, such as 48% sodium hydroxide, alkali treatment of ph12, acid of ph2 and ph1 in stages processing and so on...

There is no need to deliberately do wrong experiments for this repeated experiment, what should be done or how to do it, and the final answer should be similar to the results of his published papers. Since Jiang De can measure the content of coenzyme q10, the result cannot be fabricated.

Yang Rui hoped to complete the solution ratio as soon as possible. After avoiding two items, both Jiang De and Ding Yaqin also discovered the secret.

Jiang De remained calm, but squeezed over with a smile, and said, "Student Yang, let the lab assistants do the work of mixing the solvents, and the other students don't need to help, the lab is too small and too messy. "

No matter what he said, he was also a leader from the Provincial Education Bureau. Although he had only graduated for two years, he still coaxed and pushed him out.

At this time, a few boring cadres came back and filled the laboratory again.

Yang Rui glanced at Jiang De and Ding Yaqin, pursed his lips, and thought: If you do this, you can't blame me for not giving you face.

"Okay, it just so happens that this is troublesome to match, so I'll leave it to Section Chief Jiang." Yang Rui took the initiative to give up his position, but he took a big step in his heart.
