Chapter 90

Although Chinese university education in the 1980s was purely elite education, it was limited to financial resources and accumulation. In terms of experiments and practice, it did not necessarily guarantee that ordinary college students would have more knowledge than later college students.

But on the other hand, the key majors of graduate students and prestigious universities at this time were pure elite education. For example, schools such as Tsinghua University, Peking University, and University of Science and Technology have arranged for super-awards to directly lead undergraduate classes. It is very common for academicians of the Academy of Engineering to choose two students as assistants. This kind of training will be rare after more than ten years, and the so-called postdoctoral fellows will not receive considerable treatment.

The frequent appearance of great people among college students in the early 1980s was closely related to the education system at that time. Whether it was academic, management, or official, experience was an extremely important asset. College students in 30 years later may have never touched those top instruments when they were in their senior year, but in the 1980s, there were many freshmen who could get such opportunities.

There are few teachers and students nowadays. They are not professors who are awesome in heaven, and they dare not say that they can have several mentors and assistants under them to help with their work. They have not started recruiting doctoral students in 1982, and graduate students are recruited directly and have not received undergraduate training. Therefore, many students who seem very spiritual may enter the laboratory of a great man and participate in some crucial experiments once they are full of luck.

With similar opportunities, students in future generations may have to wait for 20 years.

If Jiang De graduated from Hedong University with a master's degree, Yang Rui said that he would not do repeated experiments on the spot. Extracting coenzyme q10 by saponification cannot be said to be an amazing invention, but it also represents a large 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 President Zhao is unhappy, it will be useless.

However, since Jiang De is a chemistry undergraduate at Hedong University, it is unlikely that he will know all the experimental procedures of the biology major.

With the wealth of the university at this time, it is probably impossible for students to conduct cross-examinations between different departments. At least, ordinary students cannot get such treatment.

"The experiment may take a long time." Yang Rui was not ready to perform the experiment, so he was ready to use the first move first and drag it out first.

He took out the raw material suspension from the refrigerator, which is the initial extract of the pig organs. This thing needs to be made with a tissue mixer. The principle is similar to that of the juicer. It uses a large amount of electricity and has a high operational pollution. Yang Rui thought about it for a while and decided to use the primary raw materials from Xibao Meat Converged Factory first.

After looking at the label on the test tube, Yang Rui handed it to Jiang Dedao: "You can use an ultraviolet spectrophotometer, and first determine the content of coenzyme q10 in the raw materials."

Jiang De took the initiative to express himself, and said that after reading Yang Rui's article, he naturally knew how to measure the content of coenzyme q10 by ultraviolet spectrophotometer.

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

Jiang De glanced at the test tube in embarrassment and said, "I think the test tube is sealed well, otherwise, use the above mark to make preliminary data?"

Yang Rui smiled: "Everyone is watching, we should be more rigorous."

He usually uses the mark on the test tubes directly. Although the organ biochemical workshop of Xibao Meat Connection Factory is backward, it is finally a bit basic and does not have an error of order of magnitude. As for the experiments done by Yang Rui, he does not need to be accurate to less than 1 percentage point. Of course, he occasionally checks the content of suspended objects in the refrigerator, and most of these tasks are actually handed over to Wei Zhenxue.

The latter is still from the Institute of Coal Science and Technology, so it is difficult to appear today.

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

"Okay, let's go step by step, you can also remember, we will have to measure the content of other products later." Yang Rui wrote a paper to increase production, so how can it be if the content is unmeasured?

Jiang De couldn't say anything to refute and nodded silently.

He originally thought that he was several years older than Yang Rui, so he should have easily manipulated him in his palm, but he did not expect that after Yang Rui entered the laboratory, he exuded a strong aura.

In Jiang De's eyes, there are only a wide range of instruments at most. After all, except for ultraviolet spectrophotometers and mechanical analysis balances, the instruments are relatively rough. However, Yang Rui's attitude of preparing for experiments and assigning work made Jiang De recall his college days.

You have encountered an experimental guidance that has a higher academic level and experimental familiarity than you. What can you do except 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 freshness of everyone had long passed. Seeing Yang Rui shake the bottle, I felt very bored.

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

"It will take several hours." Yang Rui said without looking back in his white coat.

The cadre hesitated and said, "Otherwise, let's go to visit other facilities of the school first and then see the results when you come back? Classmate Yang, can you finish it in 3 hours?"

"It will take at least 6 hours." Yang Rui hoped that they could not wait and leave quickly. After 6 hours, it would be great if these cadres who had eaten dinner and had enough wine to open their eyes to see people. What else can they do to see?

Without waiting for others to express their opinions, Ding Yaqin smiled and said, "It doesn't matter if it takes six hours. Just give me a cup of tea. You can go and visit first."

Where can I visit a school that is as big as a palm?

Seeing that Ding Yaqin was about to stay, Jiang De suddenly felt very motivated, and seemed to feel that the connection between himself and the beauties from Beijing had become closer.

Yang Rui frowned secretly. Anyone who works in biology must do three things: setting fires, viruses and journalists.

Because biology is really special. People who do physics make atomic bombs, contact aliens, and make even more terrifying particle accelerators. They act like I am not afraid of the destruction of the earth. The media occasionally jokes that ordinary people don’t care at all, and at most they only oppose the nuclear power plant in front of their homes.

It’s different for those who do biological life. Cloning is such a great achievement. As a result, it is criticized by people every day. Some high school creatures who fail to score 50 can also talk about human embryos and nuclei... If there is no media promotion, there will be no such mess.

Human IVF started in 1978 and has also been controversial. Countless people have posed ethical benchmarks and attacked them wantonly with the cooperation of the media. The researchers did not win the Nobel Prize in Medicine until 2010. Before that, 5 million couples around the world had a successful family.

Yang Rui is very suspicious that Ding Yaqin has a tendency to turn into a black man.

Is it necessary to reprint a newsletter from Hedong Education Newspaper? Is it necessary to keep an eye on myself for 6 hours of experiments? It has been done for 3 hours now, which adds up to 9 hours. In a small and difficult-to-ventilate ordinary laboratory, this is absolutely uncomfortable and unnecessary.

All the photos that should be taken were taken, and the reprinting communication of hundreds of words did not require any modification.

Could it be that I came here on a long distance and felt unwilling to accept it?

Writing a bad article is definitely more targeted and more likely to cause sensation than writing a red article.

If she had changed to a steady reporter in her forties or fifties, Yang Rui would probably think about it. But looking at Ding Yaqin's early 20s and looking very superior, she was really not sure.

Perhaps, national newspapers will not easily publish bad articles, but who can tell this clearly?

Reports such as "fake papers" and "gunners write papers" may destroy their college entrance examination qualifications - the strength of Chinese journalists taking things out of context should not be underestimated. It will be even more difficult to clear away the stigma in the future.

"Secretary 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, let’s use petroleum ether to fumigate first.

Kerosene bacon still feels very consistent with the Chinese recipes.

Ding Yaqin covered her nose with her hands, but she had no intention of quitting.

Continuous extraction tests, extraction tests finally reached the real mid-term steps.

Yang Rui thought about it, said a moment, walked out of the laboratory, first found He Cheng and Cao Baoming, then found Liu Shan, and then gave instructions to each of them before coming back with no confidence.

Cao Baoming is tall and suitable for blocking his vision. He Cheng is familiar with the experiment and knows which steps are more critical. As a girl, Liu Shan is not particularly difficult to talk to Ding Yaqin.

In fact, the best choice is to let Jiang De and Ding Yaqin chat. However, due to the trend, Jiang De's courage is quite insufficient.

When only he knew the key points in the entire laboratory, Yang Rui secretly took apart the experimental steps.

When comparing compound solvents such as ethane, methyl isobutanone, butanol, ethyl acetate, Yang Rui first mixed half or even one-third, and then completed the final preparation under the cover of the instrument, hands and classmates.

Yang Rui's main theoretical basis for extracting Coenzyme q10 by saponification is that the Coenzyme q in water is alkali-resistant. At the same time, phospholipids containing Coenzyme q that cannot be saponified can be obtained with solvent extraction and high yield.

Therefore, the key to the problem is actually to find suitable solvents that are insoluble in water.

This is a simple and cumbersome experiment.

If you don’t know the answer, you can almost use trial and error methods. That is, test one by one. How about 50% sodium hydroxide? Is it better to heat 50% sodium hydroxide to 100 degrees, or to heat to 80 degrees? Is it better to bathe for 3 hours? Or to 30 minutes?

When the parameters are too high to a certain number, trial and error methods are definitely something that kills students. There are hundreds or thousands of experiments. The supervisor in charge of the project will not do such a job, so it will only be handed over to students. To be honest, many of the 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. The 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 in those days.

Yang Rui’s advantage is that he has a well-formed paper, so he doesn’t need a cheap experimental assistant, just use the answers he tried, such as 48% sodium hydroxide, alkali treatment of ph12, acid treatment of staged ph2 and ph1, etc.

There is no need to do a wrong experiment in this repeated experiment, and the final answer should be about the same as the results of his published paper. 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, Jiang De and Ding Yaqin also discovered the mystery.

Jiang De kept silent, but smiled and squeezed over, saying, "Student Yang, let's leave the work of solvent preparation to the experimental assistant to complete. Don't help the other students. The laboratory is small and it's too messy."

After all, he was also a leader from the Provincial Education Bureau. Although he had only graduated for two years, he still sent people out with coaxing and pushing.

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

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

"Okay, it's just a matter of troublesome match, so let's leave it to Section Chief Jiang." Yang Rui took the initiative to give up his position, but took a big step in his heart.
