Journals like "acs Chemistry Biology" are about the mid-range to high-end level in native English speakers, while in China, which is just beginning to open its eyes to see the world, the high-end ones can no longer be high-end.

A few years ago, such journals were still internal journals and could not be seen in ordinary universities.

In recent years, the atmosphere of learning English in universities is very strong. Students are studying, hoping to study abroad for public expenses, and teachers are also studying, and they also want to study abroad or be visiting scholars.

However, they didn't have much time to study, and even in Beijing schools, there were not many teachers who could reach the level of CET-6 in later generations. "Acs Chemical Biology" is enough to look up to.

Tu Xian and Youyou smiled proudly and said, "I read it yesterday, which is a little more than 4.5. They have published two articles."

"Two acs, it's amazing." This person used the wrong abbreviation, and no one cared about it.

Everyone expressed their envy to the fullest, and then they dispersed.

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

The research direction he has selected is plant extraction, which is moderate in difficulty, the experimental conditions are more in line with the chemical engineering department, and the results are relatively valuable, which are similar to the research results of Yang Rui that he saw in the journal.

The extract of solanol made by Yang Rui can come from tobacco leaves or potato leaves. The former is a mature research, while the latter is a study that seems to be more economically valuable. The common one is foxglove, which can be used for the treatment of heart disease. The famous one is paclitaxel, which is extracted from the bark of fir trees. It is known as the last line of defense for cancer. It has outstanding efficacy against many advanced cancers and can effectively prolong the lifespan of cancer patients. However, it is expensive, with more than 2 million yuan per kilogram, which is really exchanging money for life.

From a familiar perspective, any Chinese medicine, or any plant, can extract active ingredients, but further research will only be more difficult.

For example, the production route from solanol to coenzyme q10 naturally increases the value of solanol, but this step is a route that many people have tried but have not been able to follow.

Tu Xian has a good foundation, but in the field of plant extraction, it can only be said to be an introductory one. Therefore, Tu Xian explained his understanding in a humble tone and accompanied by some questions.

Yang Rui's reply was all about answers to the questions.

It can be said that it helps a lot!

Tu Xian is already a lecturer. In the university system, this position is higher than that of assistant professors and lower than that of associate professors. It is a transitional stage for middle-aged and young teachers. If you are an undergraduate graduate, you usually make progress in just 5 years. College students will have to add another three or four years. However, no matter what title you are, Tu Xian has left the category of students and the category of newcomers. If you want to continue studying, you will pay more attention to opportunities.

A high-level professor has to be willing to teach you. At the same time, the research scope is similar and overlapping, and this kind of good thing is hard to come by.

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 very busy, it is common for his subordinates to not see him for several months.

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

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

He looked at every word on the envelope greedily, savoring the meaning of it carefully, as if he was chewing bones, hoping to suck out everything inside.

In the evening, Tu Xian did not go to the cafeteria for dinner as usual, but asked someone to help bring the meal, and continued to stay in the laboratory and began to conduct verification experiments.

Yang Rui wrote not long, but there was a lot of content involved. In this way, he would not write too detailed. If Tu Xian wanted to understand all the content, he had to do his own experiments.

Tu Xian was extremely excited.

Three days later.

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

After sending the letter, Tu Xian was full of inspiration and couldn't wait to start writing a new paper.

It was also a week, but it was still a express delivery. When I arrived at Beijing Iron and Steel College, some stamps were included in the envelope, and Tu Xian asked him to use express delivery to communicate the manuscripts.

Before the Internet age, the inefficiency of information transmission was outrageous. Calls to Beijing were busy for a long time, and telegrams were not suitable for non-verbal information transmission. The express delivery industry did not exist. The relatively expensive price of express delivery can only be guaranteed to go from the provincial capital to Beijing within three days. The express delivery sent by Yang Rui was asked to take Shi Gui to Pingjiang and then send it.

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

Yang Rui sent it back again. This time, he asked Tu Xian a question as if he was taking the exam.

Tu Xian answered extremely respectfully like a primary school student.

The two of them were like pen pals, and they kept communicating with letters.

In less than two months, Tu Xian became dissatisfied.

He now also understood Yang Rui's mentality of asking him to use express delivery.

Every time you get in and out, it takes a week to get in and out, which is really a waste.

Although properly arranging time can improve some efficiency, it is still not as convenient as talking face to face.

The idea of ​​inviting Yang Rui to Beijing Iron and Steel Academy has emerged again.

It was not like more than a month ago. This time, Tu Xian thought about it more and more reliable.

He absolutely recognizes Yang Rui's level, and in terms of this, in the current academic community, Zhao Yun from Changbanpo, is enough to fight in and out.

The key to the problem lies in Yang Rui's idea.

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

After another letter exchange, Tu Xian couldn't help but send a letter to Yang Rui, expressing his request to go to Hedong Province to visit him in person.

He didn't wait for Yang Rui's reply, but he found a friend that day, bought a train ticket to Pingjiang City, and prepared to go there and transfer to Nanhu Xibao Town.

Sitting on the train, Tu Xian made up his mind: no matter what request Yang Rui made, he had to try his best to invite him to Beijing Iron and Steel College. Even if he could not find anyone, he would ask him to give lectures.

Beijing Iron and Steel University wants to be a Beijing University of Science in a period of thirst for talent. A professor of biology who has enough weight is simply a pie falling from the sky.

Tu Xian reported to the department head just after understanding Yang Rui's situation.
