Chapter 218

A week later, Yang Rui's reply was sent to the mailroom of Beijing Iron and Steel Institute.

Seeing that it was express mail, the old man in the mail room found a student to guard the door for him, and went straight to the Department of chemical engineering. A loud cry rang all over the courtyard: "Tu Xian, your express, Tu Xian, your express..."

People who don't understand it are like Japanese devils shouting for cheers.

Tu Xian nervously ran out of the office, got the express mail and tore it open.

He was worried about what was important.

Otherwise, who will send it by express mail.

In fact, there are some.

For example, Yang Rui, who doesn't think one yuan is expensive and is time-consuming.

As a result, the whole person who saw the content of Tu Xian was not good.

The man in the mail room asked enthusiastically, "what's the matter? Don't take things to heart, young people. It's comfortable to say it. Ah, there's a problem. Let's all work out a way for you, right? "

The teachers in the yard spontaneously gathered around and said, "teacher Tu, if you have something to tell us, we will help you if we can."

"If you can't, just go to the top. Be more cheeky and speak louder. There are no one or two difficult things for anyone. Don't be polite when you need them."

One by one, everyone gave the idea, saying that it was a matter of fact. In recent years, the living conditions of ordinary people are not good. When they work in a university in Beijing, even if they are outstanding, their relatives and friends need help, and their hometown is busy, they usually look for these outstanding children.

Therefore, school teachers receive express mail, often accompanied by requests for help.

As soon as people saw Tu Xian's expression, they felt that eight or nine would never leave ten.

However, the result is far from the topic.

Tu Xian had to interrupt them with a wry smile, saying, "it's not what you think. It's nothing."

"What's that like?" The porter was not satisfied.

Tu Xian accompanied carefully and said, "it's a letter from a professor. Someone else may have sent it by express mail if they have conditions."

The old man lengthened his voice, "Oh," and said, "I said, how big a matter is there to send by express mail? Now people are sending telegrams. I'll send your manuscript to the post office. "

The lecturer next to him said enviously, "is this the person in the post office? Send a manuscript by express mail, too. "

"It should not be in the post office. Maybe my family is in the post office." Tu Xian himself is guessing.

"What's in the mail?" He and his teacher in the Chemical Engineering Department asked on the spot.

Tu Xian didn't mean to hide it either. He raised it with a smile and said, "it's just an exchange. I asked a few questions and they answered them."

"Is this man powerful?"

"Published in ACS chemical biology." If he says individual names, others may not be sure. ACS, as the abbreviation of American Chemical Society, is unknown to teachers of chemical engineering department.

Almost immediately, someone gasped: "SCI journals?"

"There are more than four factors."

"It's almost five last year. Maybe it's still high this year." The impact factor is calculated once a year, which is the ratio of the number of citations and published papers of the journal in the past two years.

If it is quoted, it shows that some people have further development and Research on this basis, which naturally proves the value of the article. After all, a research team, a research group, or an individual researcher spends a lot of money and time on research, and has made achievements, which are included in other SCI journals. It can't be joking. Obviously, the papers cited by them can't be joking.

Journals such as ACS chemical biology, in English speaking countries, are at the middle to high-end level, while in China, which is just beginning to see the world, the high-end level can no longer be high-end.

A few years ago, such a journal was still an internal journal, which could not be seen in ordinary universities.

In recent years, the atmosphere of learning English in universities is very strong. Students are learning English, and they expect to study abroad at public expense. Teachers are also learning English, and they also want to study abroad or be a visiting scholar.

However, after all, they don't have much time to study. Even in schools in Beijing, there are not many teachers who can reach the level of CET-6 for future generations. ACS chemical biology is enough to look up to.

Tu Xian and you Rong Yan laughed and said, "I saw it yesterday. It's 4. It's more than five. I've published two articles. ""Two ACS, great." This one uses the wrong abbreviation, and no one cares.

Everyone expressed their admiration heartily, and then dispersed.

Tu Xian returned to the office, took out Yang Rui's reply letter and read it seriously.

At present, his research direction is plant extraction, which is moderate in difficulty. The experimental conditions are more in line with the Department of chemical engineering, and the results are also more valuable, which is similar to Yang Rui's research results he saw in the journal.

The solanesol extracted by Yang Rui can come from tobacco leaves or potato leaves. The former is mature research, while the latter seems to be more economic research. The most common is Digitalis pubescens. Its extract can be used for the treatment of heart disease. The famous one is taxol, which is extracted from the bark of Cunninghamia lanceolata. It is said to be the last line of defense against cancer. It has outstanding curative effect on a variety of advanced cancers and can effectively prolong the life of cancer patients. It's only very expensive. It costs more than 2 million yuan per kilogram. It really costs money for life.

From the familiar direction, any kind of traditional Chinese medicine, or any kind of plant, can extract effective ingredients, but further research will only be more difficult.

For example, the production route from solanesol to coenzyme Q10 naturally increases the value of solanesol. However, many people have tried this step, but they have not followed the route.

Tu Xian's foundation is very good, but in the field of plant extraction, he can only be said to be a beginner. Therefore, in his first letter to Yang Rui, Tu Xian explained his understanding in a humble tone, with some questions attached.

Yang Rui's reply was full of answers to questions.

It can be said that it is a great help!

Tu Xian is already a lecturer. In the university system, his position is higher than that of a teaching assistant and lower than that of an associate professor, which is a transitional stage for young and middle-aged teachers. If he is a graduate of an undergraduate course, he can usually make progress in five years, and College Students need another three or four years. However, no matter what his title is, Tu Xian has been separated from the category of students and new people, If you want to continue to study, you will pay more attention to opportunities.

A high-level Professor needs to be willing to teach you. At the same time, the scope of research is similar and overlapping. This kind of good thing can be met but not sought.

If Tu Xian joins a team, he can also get the help of the team leader. Of course, there is no guarantee. If the team leader is very busy, it is common for his subordinates not to see him for several months.

In the Chemical Engineering Department of the Institute of iron and steel, Tu Xian couldn't find a team.

Yang Rui's answer is of great significance to Tu Xian.

He greedily looked at every word on the envelope, carefully tasted the meaning, like chewing a bone, hoping to suck everything out.

In the evening, instead of going to the canteen for dinner as usual, Tu Xian asked someone to help him with the meal. After that, he continued to stay in the laboratory and began to do the verification experiment.

Yang Rui's letter is not long, but it involves a lot of content. In this way, his writing will not be too detailed. If Tu Xian wants to understand all the contents, he must do his own experiments.

Tu Xian was very excited.

Three days later.

Tu Xian wrote another letter, describing the problems encountered in his verification test.

After sending the letter, Tu Xian was inspired and couldn't wait to write a new paper.

In the same week, it was still express mail. It arrived at Beijing Institute of iron and steel. Some stamps were attached to the envelope, and Tu Xian was asked to send and receive manuscripts by express mail.

Before the Internet age, the inefficiency of information transmission was appalling. The telephone line to Beijing was busy for a long time, and the telegram was not suitable for the transmission of non-verbal information. The express delivery industry did not exist. The relatively expensive price of express delivery could only guarantee that the express delivery from the provincial capital to Beijing within three days was sent to Pingjiang by Shi GUI.

Tu Xian didn't know why Yang Rui was so particular about time, but with his request, he immediately sent out a new letter, which made the problem even more difficult.

Yang Rui sent it back again. This time, he asked Tu Xian questions like an exam.

Tu Xian answered respectfully like a pupil.

Like pen pals, the two kept on exchanging letters.

In less than two months, Tu Xian became dissatisfied.

Now he also understands Yang Rui's psychology of asking him to use express mail.

Every time you send and receive a letter, it takes a week. It's a waste of time.

Although proper arrangement of time can improve some efficiency, it is not convenient to talk face to face.

The idea of inviting Yang Rui to Beijing Institute of iron and steel came into being again.Unlike more than a month ago, this time, the more he thought about it, the more reliable he felt.

Yang Rui's level, he is absolutely recognized, and there is this point, as far as the current academic circles are concerned, is Changbanpo's Zhao Yun, enough to fight in and out.

The crux of the problem lies in Yang Rui's ideas.

In addition, it is almost the right time, place and people.

After another exchange of letters, Tu Xian didn't hold back and sent a letter to Yang Rui, saying that he wanted to go to Hedong province to visit him in person.

Without waiting for Yang Rui's reply, he found a friend on the same day and bought a train ticket to Pingjiang City, where he was going to transfer to Xibao town of Nanhu.

Sitting on the train, Tu Xian was determined to invite Yang Rui to Beijing Institute of iron and steel no matter what he asked. Even if we can't find people, we should invite them to give lectures.

Beijing Institute of iron and steel wants to be Beijing University of science. It's the stage of thirst for talents. A professor in biology department with enough weight is a pie from the sky.

When Tu Xian learned about Yang Rui, he reported to the head of the Department.
