Cheng Ran had a faint soapy fragrance on his body, and after arriving in the room, he personally brewed a cup of jasmine tea for the two of them, which was the most ordinary kind sold on the street.

"Dean Gao, drink tea. ”

Gao Yueyang respected Cheng Ran very much, took the teacup with both hands, nodded and said thank you.

"Academician Cheng, if you have worked, don't bother. ”

Cheng Ran smiled and didn't say much, his thin face was already full of wrinkles, but his black hair showed his spirit.

"Dean Gao, is there something wrong with coming here today?"

Gao Yueyang put down the teacup and nodded: "Well, I have something important to ask for help from Cheng Yuan today." ”

After speaking, Gao Yueyang pulled Bai Ye over and introduced him to Cheng Ran: "Academician Cheng, this is Bai Ye, and he is also a professor of our Tsinghua Concord. ”

When Cheng Ran heard this name, he suddenly came to his senses, and his eyes under the black-rimmed glasses looked at Bai Ye with interest.

Then he smiled with interest and said, "Oh, Bai Ye, I have long admired the great name, a rising star in the academic world, and a talent in the medical field, I have heard your name a lot." ”

Obviously, Cheng Ran is no stranger to such a name, on the contrary, there are some curiosities and expectations.

Bai Ye smiled awkwardly: "Hello Teacher Cheng, I am just a waste of fame, unlike a real scientific research worker like you, who has made so many contributions to what I have done." ”

Cheng Ran was not as rigid as he looked on the outside, but joked: "Don't be modest, more than half of my students are your fans." You are now the idol of half of Tsinghua students, which is a good thing, at least a correct value orientation. ”

After the three of them chatted for a while, Bai Ye said directly: "Teacher Cheng, I came here today to discuss something with you, do you know cobalt-chromium alloy?"

As soon as Cheng Ran heard about cobalt-chromium alloy, he also listened carefully for a while, because he himself is engaged in chemistry and materials, and he is also very good at research in the field of rare metals.

And when he heard Bai Ye say about cobalt-chrome alloy, Cheng Ran thought of some recent things and suddenly understood something.

And Bai Ye then chatted with Cheng Ran about the cobalt-chrome alloy, and explained the ins and outs.

Bai Ye then said: "Teacher Cheng, my main purpose this time is mainly how to remove the residual cobalt and chromium ions in my body. ”

After Cheng Ran heard this question, he couldn't help but pause: "It is actually difficult for inert metals like cobalt and chromium to react in the human body, and I have also studied cobalt metals, and I also participated in the research when the domestic production of cobalt-chromium alloys was used in the biomedical field. ”

"This substance...... What to say, generally speaking, under normal circumstances, it is not easy to have a human reaction, I also read your paper, and it is very meaningful to write, and the idea is novel, especially one thing you said is particularly reasonable, that is, the safety test of biology, perhaps it should not only be evaluated in the normal human body, as you wrote in your paper, cobalt-chromium alloy will undergo some abnormal ionization under pathophysiology, and mild corrosion, this situation is not an exception, because we have found the appearance of cobalt-chromium metal ions when we were in research and development, but at that time, because it was an example, and the results of statistical software analysis showed that it was not statistically significant, we also did not pay attention to it. ”

"Now it seems that this matter is not as simple as it seems. It was a dereliction of our duty at that time. ”

Speaking of this, Cheng Ran sighed and said meaningfully: "Hey...... It seems that scientific research is really a work that must pursue its causes, and it is impossible to be sloppy at all, and any existence is meaningful, and the reasons should be figured out. ”

Bai Ye saw that Cheng Lao was very interested in this research, so he said: "Academician Cheng, I am going to apply for a project for this work, and I invite you to join our research group, the main purpose is to target the cobalt and chromium ions scattered in the body. ”

In fact, removing cobalt-chromium ions from the body is not as simple as thought, because these things will behave differently in different places, and one method cannot be used, and when these ions enter different cells, the degree of binding is also different.

As a master in the field of rare metals, Cheng Lao is also strong in the research of biochemistry, and Cheng Lao is one of the people in charge of the research and development of contrast agents in China.

Cheng Ran nodded: "To be honest, I am very interested in this topic, if you don't come to me, it is likely that in a month, I will also go to you, this is a work that benefits the country and the people, and involves the health of millions of people, I naturally will not miss it." It's just that...... Project Leader......"

Before Cheng Ran finished speaking, he was interrupted by Bai Ye: "Academician Cheng, I have already thought about this problem, it is better for you to do the project leader, I am young and not qualified enough, and I can't do such a large-scale project, so after thinking about it, I decided to invite you to do this project." ”

After listening to this, Cheng Ran smiled and waved his hand: "No, no, no, I have also thought about this matter clearly, you will do this topic, you will be the person in charge, and you will be responsible for the relevant matters of this project as a whole." ”

"I've inquired about your relevant experience, a bit of a wild background, although capable, but lack of a normative and systematic growth, this is not a good thing, this topic is very good, I think you can take it as an opportunity to exercise. ”

Of course, Cheng Ran didn't say something in his heart, no matter what awards are selected in the world, the person in charge of the project is used as the selection criteria.

If you're just a participant, you don't usually count towards a big achievement.

This is also what Cheng Ran wants to do, Bai Ye has won the Best Contribution Award, but this award is not an award such as the Science and Technology Progress Award and the Achievement Award.

Bai Ye can be rated as a Changjiang Scholar with his best contribution, but if it weren't for the selection of that group of old people, it would be difficult for Bai Ye to go up.

Scientific research work is the most important achievement, and it is a real achievement.

Cheng Ran knew that he was old, he had no chance to win the Nobel Prize in this life, and the Wolf Prize in Chemistry was already his peak, but Bai Ye did not say anything, if after this exercise, Bai Ye could grow up and become a leader in the field of domestic scientific research.

Idols are sometimes the best teachers.

If Bai Ye can drive the development of this group of young people, this is really a great event and a happy event worth celebrating, if it can really be like this, Cheng Ran is happy from the bottom of his heart.

A group of amazing scientific researchers is the future of the motherland, and it is worth more than a Nobel Prize.

So, speaking of this, Cheng Ran continued: "However, I have one condition. ”
