Chapter 110 The devil will never let you down! (Please subscribe)
Xiao Xiba's attitude of never giving up made it clear that he was asking for a slap in the face, so Zhang Wei decided to meet his request.

So Zhang Wei asked: "Is the solvent you used methanol or acetonitrile?"

"It's methanol!" the female assistant researcher replied.

"What about the concentration? 50% or 55%?" Zhang Wei continued to ask.

"55%." The female assistant researcher's tone has become serious.

Being able to ask whether methanol or acetonitrile is used as a solvent, and whether the concentration is 50% or 55%, is definitely knowledge that only an expert can master.

"It's not that 55% methanol solvent cannot be used, but in your experiment, using 55% methanol will not achieve the best experimental results. If I read it correctly, your experiment needs to maintain the activity of the enzyme, right? ?" Zhang Wei continued.

"How do you know? Do you want to do this experiment?"

The female assistant researcher's rhetorical question also confirmed that what Zhang Wei said was correct.

Zhang Wei did not answer, but said; "In DESI experiments, the best solvent or solvent combination depends on the specific analyte and experimental conditions. Since you want to maintain the activity of the enzyme, you should choose non-volatile solvents with high salt content." Solution as solvent!”

"Are you talking about sodium chloride?" the female assistant researcher asked with a frown.

Zhang Wei shook his head: "Although sodium chloride is better than methanol, it is not the best choice. I think the best solvent should be sodium sulfate."

The female assistant researcher immediately fell silent. She was thinking about whether what Zhang Wei said was right.

Seeing that the situation was not good, Huang Junji immediately spoke to disrupt the situation: "You said to use sodium sulfate, then you have to use sodium sulfate! You must be right!"
You are just an exchange student from China, and you are not an industry authority! There are so many outstanding researchers at Lawrence Berkeley National Laboratory, are they not as good as you? "

"What he said is right!" A voice suddenly sounded, and everyone looked in the direction of the voice. A Chinese man in his fifties, wearing glasses and looking a little thin, was walking towards this side.

Seeing this man approaching, several researchers who were sitting in front of the computer immediately stood up, looking very respectful.

"Director, why are you here!" Someone immediately came to greet him.

The Chinese man waved his hand and then looked at Zhang Wei: "This classmate is right. If you want to retain the best activity of the enzyme, a high-salt content non-volatile solution is indeed a better solvent choice. Sodium sulfate should be used. It’s also more effective than sodium chloride!”

"The Chinese are against the Chinese!" Huang Junji muttered dissatisfiedly.

The researcher next to him said: "Let me introduce to you, this is Steven Chu, the director of Lawrence Berkeley Laboratory!"

"It turns out it's him!" Zhang Wei showed a surprised expression.

"Do you know him? Are you an acquaintance?" Ye Haotian asked in a low voice.

Ye Haotian felt that the person who suddenly came out and spoke for the big devil was probably an acquaintance.

"Don't you want to meet the Nobel Prize winner? He is it! Steven Chu, the 1997 Nobel Prize winner in Physics!" Zhang Wei said.

"Chinese Nobel Prize winner? He seems to be somewhat impressed." Ye Haotian said.

"Following Yang Chenning, Li Zhengdao, Ting Zhaozhong, and Li Yuanzhe, he is the fifth Chinese scientist to win the Nobel Prize." Zhang Wei went on to explain.

Zhang Wei's ordinary memory is not enough to remember every Nobel Prize winner. But this Steven Chu is indeed a bit special. In addition to being Chinese, he will also become the Secretary of Energy of the United States in the future, so he looks familiar to Zhang Wei.

Steven Chu has served as the director of Lawrence Berkeley Laboratory since 2004, and is also the first Chinese-American head of the laboratory.

When the big leader arrived, all the researchers around him stopped what they were doing and stood up respectfully. The exchange students who came to visit also showed solemn expressions.

The female assistant researcher's frown instantly relaxed. Since Zhu Diwen said that Zhang Wei's solvent solution was right, then it must be right.

Huang Junji looked embarrassed again.

He just finished saying that you are not an authority in the industry! An industry authority really came right away.

And he is also a top authority with the right to speak. Not only is he a Nobel Prize winner, he is also the head of the entire Lawrence Berkeley National Laboratory!

The slap in the face was a little too fast, and Huang Junji himself didn't even react.

Zhu Steven looked at Zhang Wei and asked: "This classmate, which university are you an exchange student at?"

"Hello, director, I am from Tsingta University of China, and my name is Zhang Wei." Zhang Wei replied.

"Tsinghua University! My father also graduated from Tsinghua University." Zhu Diwen smiled, probably because he felt that he had some connection with Zhang Wei.

Steven Chu's father graduated from the Chemistry Department of Tsinghua University in 1940, and then studied in the United States and received a PhD in chemistry from the Massachusetts Institute of Technology. Zhu Diwen's grandfather, Li Shutian, served as the Minister of Education during the Republic of China.

Those who could stay in the United States in those days were either rich or noble.

Steven Chu then asked: "Classmate Zhang, how did you come up with the idea of ​​using a non-volatile solution with high salt content as a solvent?"

"After knowing the principle of EDSI, it should not be difficult to think of it!" Zhang Wei said with a smile.

"This is not easy. All the researchers here know the principle of EDSI, but no one has ever thought of using sodium sulfate as a solvent."

Steven Chu then asked: "Besides solvents, what else did you think of?"

"Many, the existing EDSI technology is not mature yet, and there are many areas that can be improved." Zhang Wei said with confidence.

Now that the big boss Zhu Diwen has appeared, Zhang Wei feels that it is time to show off, and there is no need to hide it.

Americans have always been accustomed to speaking from the standpoint of strength and status, and fists are the language that Americans can best understand. And showing your fists in front of a big boss is definitely more effective than showing your fists in front of ordinary researchers.

Sure enough, when Zhang Wei said that there are still many areas for improvement in desorption electrospray ionization technology, Steven Zhu immediately asked: "What about it?"

“Optimization of spray solvent and conditions, such as the composition of the spray solvent, spray voltage, spray flow rate and other parameters, can improve the ionization efficiency and desorption capacity.

The ion transmission efficiency can be improved by improving the ion transmission pipeline and interface, using more efficient ion transmission pipeline materials and designs, reducing ion loss and diffusion, and improving signal stability and sensitivity.

Preparation of the sample surface can be more elaborate, and the use of specific coatings or modifiers can change the properties of the sample surface, making it more likely to interact with the spray solvent and ionize..."

Zhang Wei listed several areas that could be improved.

After 2010, these were the basic optimization plans for desorption electrospray ionization technology. Zhang Wei, an ordinary inspector, could propose them casually after becoming familiar with this technology.

However, in 2004, when desorption electrospray ionization technology first appeared, what Zhang Wei said was a revolutionary breakthrough in this technology!

When he first listened, Steven Chu still kept a smile on his face and acted as calm and calm as a Nobel laureate.

But as he listened, Steven Chu's smile froze, replaced by a solemn expression of serious thought.

Finally, when Zhang Wei finished speaking, Steven Chu could no longer maintain the stability of a Nobel laureate, and a ray of shock appeared on his face!

Zhang Wei's speaking speed is not fast, so Zhu Diwen can listen and think and analyze whether what Zhang Wei said is feasible.

As a Nobel Prize-level scholar, Steven Chu responded quickly. His thinking and analysis could keep up with Zhang Wei's pace. It was also true that Chu Stevens immediately realized how important what Zhang Wei said was. importance!

This is not improving technology, this is a technological revolution!

By optimizing according to what Zhang Wei said, the effect of desorption electrospray ionization technology will rise several levels, and the resulting breakthroughs in scientific research will also develop by leaps and bounds.

Not far away, Ye Haotian looked at the change in Zhu Xiwen's expression, a proud smile appeared on his face, and he was even happier than he was pretending to be.

"As expected of my great devil, he has never let me down!"

Half a minute later, Steven Chu gradually came back to his senses, and he said: "Classmate Zhang, what you said is enough to write a paper on improving EDSI technology."

"It's a pity that I don't have time, and I don't have experimental equipment to confirm my point of view!" Zhang Wei shrugged.

"Is Mr. Zhang interested in cooperating with our researchers here to complete this paper?" Zhu Diwen asked immediately.

With Zhang Wei's current situation, it is really impossible to complete this paper independently.

The technical improvement of desorption electrospray ionization still requires experiments to verify the results. Without verification of the results, there are only dry plans. That is called conjecture, not a paper.

This new technology is currently only available at top scientific research institutions in the United States, and Zhang Wei can only cooperate with researchers here.

Zhang Wei thought for a moment and nodded: "The researchers at Lawrence Berkeley National Laboratory are all excellent. I would love to be able to cooperate with the researchers here."

"In that case, which one of you is willing to cooperate with Zhang to complete this paper?" Zhu Diwen looked at the researchers around him.

"I can!" Someone immediately raised his hand, it was the female assistant researcher named Zhou.

"Hey! This girl is the first one to jump out!" Zhang Wei thought to himself.

The female assistant researcher said, "Classmate Zhang is from Tsinghua University in China. I also completed my bachelor's degree in China. It will be easier for me to communicate with Classmate Zhang in Chinese if we can use Chinese."

"Seeing that scientific research results can be produced, do you think of China now?" Zhang Wei was full of disdain.

Steven Zhu looked at the other researchers. They looked at each other without any expression.

It's not that these researchers are not interested in this paper, but they think that since Zhang Wei and the female assistant researcher are Chinese, there is no need for them to get involved.

"Classmate Zhang, what do you think about Linda Zhou cooperating with you to complete this paper?" Zhu Steven asked again.

The female assistant researcher immediately looked at Zhang Wei expectantly.

Zhang Wei didn't like this Runren in his heart, but the other researchers didn't express their feelings, so Zhang Wei could only choose her.
So Zhang Wei had no choice but to nod and agree: "I still have many tasks for exchange students to complete. I usually don't have that much time. I can only provide ideas and directions for improving technology, specific experimental steps, and writing papers. Only you can do it." Do."

"No problem, you just need to provide ideas. I will do the experiments and write the paper!" Researcher Runren nodded immediately.

"What about the signature of the paper?" Zhang Wei asked again.

"Is that okay if we sign together?" Researcher Runren said immediately.

"Then I'll have no problem." Zhang Wei nodded.

Steven Chu continued: "When the paper is finished, show it to me for a look. I am also interested in the improvement of EDSI technology!"

……

In the corner, Huang Junji looked at Zhang Wei with a gloomy face, and then silently hid the recording pen.

"You're not the only one who can write it! Whoever writes the paper first gets it!"
