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

The old man in the mailroom saw that it was an express mail, and found a student to guard the door for him, so he went straight to the Department of Chemical Engineering, and the loud shout resounded throughout the compound: "Tu Xian, your express, Tu Xian, your express ......"

Those who don't understand listen to it in their ears, as if the Japanese devils are shouting cheers.

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

He was worried about something.

Otherwise, who will send EMS if they are fine.

Actually, there are still some.

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

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

The uncle in the mailroom was still very enthusiastic and asked: "What's the matter?" Young people don't take it to heart if they have something, just say it, and it's comfortable to say it." Ah, if there's a problem, let's all help you find a way, won't we?"

The teachers in the courtyard spontaneously came around, and you said word by word: "Teacher Tu, if you have something to tell us, we will definitely help you if you can." ”

"If you can't do it, just look for it, be thick-skinned, louder, keep it up, who doesn't have one or two difficult things, don't be polite when you can use them. ”

Everyone gave their ideas one by one, and what they said was serious. In these years, the living conditions of ordinary people are not good, working in a university in Beijing, even if they get ahead, relatives and friends need help, and there is something in the family, usually looking for these children who have got ahead.

As a result, school teachers receive express mail, often accompanied by requests for help.

As soon as everyone saw Tu Xian's expression, they felt that ** was not far from ten.

However, the result is a digression.

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

"What's that?" said the janitor.

Tu Xian accompanied him and said: "It was a letter sent by a professor, and the unit may have the conditions, so they sent it by express mail." ”

The old man dragged out his voice, "oh", and said, "I said, how big is it to send an express mail, and now everyone has sent a telegram." Just send your manuscript to the post office. ”

The lecturer next to him said enviously: "This is someone from the post office? ”

"It shouldn't be from the post office, I can't say it, maybe the family is in the post office. Tu Xian himself is also speculating.

"What manuscript did you send?" asked the teacher who was also in the Department of Chemical Engineering with him.

Tu Xian didn't mean to hide, he raised it with a smile and said, "It's just to communicate, I asked a few questions, and people answered." ”

"This guy is amazing?"

"He has published an article in ACS Chemical Biology. "If he says a specific name, others may not be able to figure out the pulse, ACS is the abbreviation of the American Chemical Society, how can the teacher of the Department of Chemical Engineering not know.

Almost immediately, someone inhaled and shouted, "SCI journal?"

"There are more than four impact factors. ”

"It was almost 5 last year, and maybe it's still high this year. "The impact factor is calculated once a year, which is the ratio of the number of citations of the journal's papers to the number of published papers in the past two years.

Being cited means that someone has developed and researched further on this basis, which naturally proves the value of the article. After all, a research team, research group, or individual researcher who spends a lot of money and time doing research, and has made results, and is included in other SCI journals, cannot be a joke, and the papers cited by it obviously cannot be a joke.

Journals such as ACS Chemical Biology are about mid-range to high-end in English-speaking countries, while in China, which is just beginning to open its eyes to the world, it can no longer be more high-end.

A few years ago, such journals were in-house and could not be found in ordinary universities.

In recent years, there has been a strong atmosphere of learning English at the university, students are studying, hoping to study abroad at public expense, and teachers are also learning, and they also want to study abroad, or become visiting scholars.

However, they don't have much time to study, and even in the schools in Beijing, there are not many teachers who can reach the sixth level of English in later generations, and "ACS Chemical Biology" is enough to look up to.

Tu Xian smiled with honor and said, "I watched it yesterday, than 4." 5 More points, people have published two articles. ”

"Two ACS, amazing. "This one is the wrong shorthand, and no one cares.

Everyone expressed their envy to the fullest, and dispersed for a while.

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

His current research direction is plant extraction, which is moderately difficult, and the practical conditions are more in line with the Department of Chemical Engineering, and the results are also more valuable, which is also relatively similar to the research results of Yang Rui that he has seen in the journal.

Yang Rui's solanesol extraction can come from tobacco leaves or potato leaves, the former is a mature study, and the latter is a research that seems to have more economic value. Common foxglove, its extract can be used for the treatment of heart disease, the famous morutaxel, extracted from the bark of the fir tree, known as the last line of defense for cancer, for a variety of advanced cancer curative effect, can effectively prolong the life of cancer patients, but the price is expensive, more than 2 million yuan per kilogram, real money for life.

From a familiar direction, any kind of Chinese medicine, or rather, any kind of plant, can extract the active 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, but this step is a route that many people have tried and have not taken.

Tu Xian's foundation is very good, but in the field of plant extraction, it can only be said to be an entry, so in the first letter sent to Yang Rui, Tu Xian explained his understanding in a humble tone, and attached some questions.

Yang Rui's reply is all an answer to the question.

It can be said that it is a huge help!

Tu Xian is already a lecturer, in the university system, this position is higher than the teaching assistant, lower than the associate professor, is the transition stage of young and middle-aged teachers, if it is a bachelor's graduate, usually only 5 years can progress, college students need to add another three or four years, but no matter what the title, Tu Xian has been out of the category of students, but also out of the category of newcomers, and then want to continue to study, but pay more attention to opportunities.

High-level professors, people still have to be willing to teach you, and at the same time, the scope of research is similar and overlapping, this kind of good thing is not to be found.

If Tu Xian joins a team, he can still get help from the team leader - of course, this is not guaranteed, if the team leader is busy, it is not uncommon for his subordinates not to see him for months.

In the Department of Chemical Engineering of the Iron and Steel Institute, Tu Xian couldn't find a team even if he wanted to.

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

He greedily looked at every word on the envelope, carefully sorcering the meaning, as if chewing on a bone, hoping to suck everything inside.

In the evening, Tu Xian did not go to the cafeteria to eat as usual, but asked someone to help bring the food, and then continued to stay in the real yàn room and began to verify the real yàn.

Yang Rui's letter is not long, but it involves a lot of content. In this way, what he wrote would not be too detailed, and Tu Xian would have to do it himself if he wanted to understand all the contents.

Tu Xian was extremely excited.

Three days later.

Tu Xian wrote another letter and wrote out the problems he encountered during the verification test.

After sending the letter, Tu Xian was so inspired that he couldn't wait to start writing a new paper.

It was also a week, still by express mail, arriving at the Beijing Iron and Steel Institute, with some stamps attached to the envelope, and asked Tu Xian to use the express mail to exchange manuscripts.

Before the Internet age, the inefficiency of information transmission was outrageous, the telephone to Beijing was long-term busy, the telegraph was not suitable for the transmission of non-verbal information, the express delivery industry was not zài, the relatively expensive price of express mail could only guarantee from the provincial capital to Beijing within three days, and the express mail sent by Yang Rui was all sent by Shi Gui to Pingjiang again.

Tu Xian didn't know why Yang Rui was so particular about time, but he still followed his request, and then sent a new letter, and the problem became more difficult.

Yang Rui sent it back again, and this time, he also asked Tu Xian about it as if it was an exam.

Tu Xian replied respectfully like a primary school student.

The two were like pen pals, and the letters were constantly exchanged.

In less than two months, Tu Xian became dissatisfied.

He now also understands Yang Rui's psychology of asking him to use express mail.

It takes a week to exchange a letter every time, which is a waste.

Although proper time management can improve some efficiency, it is not as convenient as face-to-face talking.

The idea of inviting Yang Rui to Beijing Iron and Steel Institute was born again.

Unlike more than a month ago, this time, the more Tu Xian thought about it, the more reliable he felt.

Yang Rui's level, he absolutely recognizes, and with this, as far as the current academic world is concerned, it is Zhao Yun of Changbanpo, which is enough to kill in and out.

The crux of the matter lies in Yang Rui's thoughts.

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

After another letter exchange, Tu Xian did not hold back and sent a letter to Yang Rui, saying that he wanted to go to Hedong Province and visit him in person.

He didn't wait for Yang Rui's reply, he found a friend on the same day, bought a train ticket to Pingjiang City, and planned to transfer there and then transfer to Nanhu Xibao Town.

Sitting on the train, Tu Xian was even more determined: no matter what Yang Rui asked, he would do his best to invite him to Beijing Iron and Steel Institute. Even if you can't dig someone, ask him to give a lecture.

Beijing Iron and Steel Institute wants to be Beijing University of Science, which is the stage of seeking talents, and a professor of biology with enough weight is like a pie falling from the sky.

Tu Xian only waited for Yang Rui to understand the situation, and then reported to the head of the department.
