They’re all reborn, what’s wrong with being a little more almighty?

Chapter 109: It’s itchy and it’s time to ache! (Please subscribe)
The next item on the exchange students’ agenda is to visit the Lawrence Berkeley National Laboratory, the real face of the University of California, Berkeley.

Lawrence Berkeley National Laboratory is located in the back of the University of California, Berkeley. It is one of the three major national laboratories in the United States. It is affiliated to the U.S. Department of Energy and is specifically operated by the University of California, Berkeley.

Since its establishment, Lawrence Berkeley National Laboratory has contributed hundreds of world-class research results, many of which have truly changed human history.

For example, the atomic bomb is inextricably linked to the Lawrence Berkeley National Laboratory.

Oppenheimer, the leader of the Manhattan Project, was a professor at Berkeley at the time. The success of the Manhattan Project also benefited from the technical support of Lawrence Berkeley National Laboratory.

Although Lawrence Berkeley National Laboratory is not open to the public, it often holds public events and lectures, and relevant scholars can also apply to visit.

In addition, students at the University of California, Berkeley, have special privileges. Generally, applications for collective visits will be approved.

After wandering around the perimeter of Lawrence Berkeley National Laboratory, the exchange students put on white coats, shoe covers, hair covers and masks, and entered an experimental area under the guidance of the instructor.

“Lawrence Berkeley National Laboratory has the best equipment in the world, and of course it also has the most advanced experimental methods in the world. There are many advanced equipment and experimental methods that you have never seen in your alma mater.

So when you visit later, please do not touch any equipment without permission, and do not enter the experimental area to avoid unnecessary trouble.

Of course, if you have any questions, you are very welcome to ask them. We are an academic research institution and we are happy to answer your confusion! "

After visiting two test areas in succession, everyone came to the third laboratory.

There is a test bench sealed by transparent glass in the front. There are several circular holes on the front. Each hole is inlaid with silicone gloves. The operator can directly put his hand into the silicone gloves and operate through the transparent glass.

Next to it, there is a row of computers displaying various data and images.

"Zhou, these are the exchange students who are here to visit. Please introduce them to everyone!" the commentator shouted to a researcher.

I saw a woman walking over. She was not tall and wore a mask and goggles. Her face could not be seen clearly, but she could tell that she was of Asian yellow race. Combined with her surname Zhou, she is most likely Chinese.

"Hello everyone, I am an assistant researcher here. We are currently conducting imaging experiments on microorganisms."

As soon as the woman opened her mouth, Zhang Wei guessed that she must be Chinese and had been educated in China. She was not a Chinese-American born and raised.

There are obvious differences between Chinese overseas students and Chinese bananas in their pronunciation, intonation and way of speaking.

Many sentences that we think have correct grammar and structure will sound strange to foreigners.

For example, as written in our textbooks, "How are you?" "I am fine. Thank you, and you?" "I am fine, too."

In daily communication among Americans, no one would say this when they are idle! If you say that, people will think you are crazy!

In terms of pronunciation and intonation, even if the English of international students can reach the level of pure American accent or pure London accent, Americans can still tell that you are an immigrant rather than a banana person through the pronunciation of many tones.

Most Chinese people who have lived in the United States and the United Kingdom for decades cannot reach the level of pure American accent or pure Cockney accent.

This is the case for the female assistant researcher surnamed Zhou. Although her English is fluent, you can tell just by listening to her intonation that she is from China.

The female assistant researcher then introduced the ongoing microbial imaging experiment. If this experiment can be shown to everyone, it is probably not an important experiment.

"In today's experiment, we used a brand-new technology. I wonder if any of the classmates know this technology? Let me remind you that this technology is related to ionization technology." The female assistant researcher instantly transformed into a lecturer.

"Is it DESI technology?" A voice sounded, and it was Huang Junji who spoke.

"This student answered correctly. What we are using now is DESI technology!" The assistant researcher nodded.

Huang Junji showed a proud smile, and the female assistant researcher then asked: "DESI technology is a new technology that has just been released recently. How did this classmate know about it?"

"My father is Hwang Woo-suk, a biology professor at Seoul National University in South Korea! He is an authoritative expert in the field of life sciences. Although DESI is a new technology, it is not unfamiliar to my father. I have heard him mention this technology , so I know something." Huang Junji looked proud.

"So Professor Huang Yuxi is your father!" The assistant researcher nodded suddenly. She also studied the field of biology and had heard of Huang Yuxi's name.

Seeing Huang Junji snarling again, Ye Haotian curled his lips in disdain and whispered, "What is that DESI technology?"

"Desorption electrospray ionization, desorption electrospray ionization technology!" Zhang Wei replied in a low voice.

"You know, why didn't you say anything just now? Let that Korean guy steal the spotlight!"

"Just pay attention to the solvent! There seems to be something wrong with the solvent they used."

"What did you say? There's something wrong with the solvent they used!" Ye Haotian deliberately repeated Zhang Wei's words in English loudly.

Ye Haotian's voice made everyone's eyes turn to Zhang Wei.

Huang Junji even frowned, why are you everywhere!
……

Desorption electrospray ionization technology is a mass spectrometry ionization technology. This technology can enable biological macromolecules with molecular weights of tens of thousands, hundreds of thousands, or even millions to be detected conveniently, sensitively, quickly and accurately using mass spectrometry technology. .

The application fields of this technology are also very wide, not only in the field of biological science, but also in environmental science, food safety, material science, pharmacy, and even forensic identification.

Desorption electrospray ionization was invented by Purdue University professor Robert Graham Cooks in 2004, so it was still a new technology at the time.

Even in the United States, only top universities and laboratories are equipped with this technology, and other countries may not have introduced it yet.

From this aspect, Huang Junji is quite knowledgeable and actually knows this new technology.

And his father, Hwang Woo-suk, is worthy of being a national treasure-level scientist in South Korea. The scientific research team he leads is quite capable and has access to this new technology.

As a reborn person, Zhang Wei is very familiar with desorption electrospray ionization. And this starts from the previous life.

In his previous life, Zhang Wei only passed the second level of the college entrance examination, so he applied for a university in his hometown. Since my scores were neither good nor bad, I had no choice but to choose a good major, and I didn’t want to accept the adjustment to a bad major, so I finally chose bioengineering. At that time, there was no beacon like Mr. Zhang Xuefeng, and ordinary people did not have access to a wide range of information. For unfamiliar majors, they could only blindly apply based on their feelings.

Zhang Wei thought that the bioengineering major sounded very high-end and should be a very qualified major, but he did not expect that it was a sinkhole major.

"Biochemical environmental materials" Tiankeng, bioengineering ranks first!
Those who study bioengineering are said to be able to work in research and development at pharmaceutical and biotech companies, and the salary is pretty good, but they all start with a master's degree from a prestigious school. If you are not among the top students in this major, you will definitely not be able to become a scientific researcher.

And Zhang Wei only studied a second degree in bioengineering. What can he do after graduating from a second degree in bioengineering? It’s very difficult to take the postgraduate entrance examination!

After enrolling in school, Zhang Wei inquired about it and found out that the most common employment direction for his seniors after graduation was to go to the laboratory department of the hospital to play shit!

Of course, that was 2004. In today's situation, it would be difficult for a bioengineering graduate to go to the hospital to play shit!

Thinking of having to play shit for the rest of his life in the future, Zhang Wei was desperate at that time!

After graduating from college, in order not to play shit, Zhang Wei chose the examination system, and it was a professional examination that was more difficult than the first level of civil servants.

Although it was difficult to take the public examination examination at that time, it was not as difficult as it is now. Zhang Wei was lucky, and he finally got a job as a business editor at an inspection center in a local county in his hometown, which was regarded as an iron rice bowl.

This kind of county-level inspection center has a wide range of services. Anything related to inspection must be inspected.

For things like food safety, animal quarantine, environmental testing, and even the public security department's inspection of material residues on broken arms and legs, you have to go to the inspection center.

Therefore, Zhang Wei is very familiar with inspection and testing. After all, it is his job to eat.

Desorption electrospray ionization technology is a technology commonly used in inspection and testing.

Although this is a new technology that was only proposed in 2004, the threshold for application of this technology is not high, so it only took about three years for it to be popularized in scientific research institutes around the world.

By 2010, many common domestic testing institutions also began to introduce desorption electrospray ionization technology.

The key is that after years of development, countless scientists have continuously improved the desorption electrospray ionization technology during use. By 2010, this technology had been improved too much and its efficiency had been improved too much.

The county inspection center where Zhang Wei is located has of course introduced the improved desorption electrospray ionization technology. Therefore, what Zhang Wei masters is also the technology that will be perfected later.

It is for this reason that after arriving at Lawrence Berkeley National Laboratory, Zhang Wei not only saw at a glance that this was desorption electrospray ionization technology, but also saw that the solvent used was quite backward.

After 2010, county-level inspection centers would not use this original solvent.

Ye Haotian, on the other hand, couldn't stand Xiao Xiba's arrogant look, and because of his unconditional trust in the Great Demon King, he deliberately spoke out loud about the problem with the solvent.

Since the big devil said there is a problem, there must be a problem!

At this time, after Ye Haotian's shout, all eyes were focused on Zhang Wei.

The female assistant researcher had a gloomy expression. Although she was wearing a mask, there was still a hint of gloom in his eyes.

I was doing my experiments properly, and suddenly a guy came over and pointed fingers, saying that there was something wrong with the solvent in my experiment, and no one would be happy.

And this guy who is pointing fingers is just an exchange student!
If you were an authority in the industry and came to point fingers, I would tolerate it.

Why should an exchange student dictate?
Did you know this is desorption electrospray ionization technology? Is it a new technology that was just invented a few months ago? Looking at scientific research institutions around the world, there are currently only a few that possess this technology!

As an exchange student, how much do you know about this new technology? Why do you think there is something wrong with our solvent?

Taking a closer look, Zhang Wei still has an East Asian face. Judging from the tone of Ye Haotian's English sentence just now, he is most likely Chinese.

At this second, the gloomy look in the eyes of the female assistant researcher instantly turned into disdain and contempt.

"I am also an undergraduate student in China. How can I not know the level of scientific research in China? How can Chinese universities have the most advanced experimental technology in the world? As an exchange student from China, you have probably never seen desorption. Electrospray ionization technology, you’re still talking about the problem with solvents!”

It is perfectly normal for Run people to look down on their compatriots from China!
In the eyes of these people, people like them who have traveled abroad must be superior to others. Even begging for food on the streets of New York is better than working as a white-collar worker in Beijing, Shanghai and Guangzhou!

Of course, Runren is not the only one with this kind of thinking. In China, there are even more people who lick someone outside and squirt inside.

Watching the highlights of the Super Bowl can bring you to a civilized country, and I will burst into tears after seeing a few F35s flying in the sky. By the way, during the Spring Festival Gala of which year, my brother from the People's Liberation Army stopped paying New Year greetings and pretended not to see it?
I saw the female assistant researcher put on a arrogant tone and said: "This classmate, if you don't understand this new technology, don't make any comments! Science is rigorous, and comments on science must also be based on evidence. Yeah, you’re not just talking nonsense!”

Huang Junji also immediately helped: "Do you know what DESI technology is? It's a new technology that was just proposed this year. If you don't understand it, don't talk nonsense!"

"DESI, Desorption electrospray ionization, is a rapid in-situ ionization technology." Zhang Wei answered.

"Even if you have heard of this technology, do you know the principle?" Huang Junji continued.

Zhang Wei immediately replied: "The basic principle of DESI is the droplet carrying mechanism, that is, the sample is dissolved in an appropriate solvent and then dropped on the surface of the insulating material, and the solvent is evaporated, and the sample is deposited on the surface of the carrier.

The spray solvent used is first applied with a certain voltage and ejected from the inner casing of the atomizer. The high-speed gas ejected from the outer casing of the atomizer quickly atomizes the solvent and accelerates it, causing the charged droplets to impact. to the sample surface.

The sample sputters into the gas phase after being struck by high-speed droplets. The charged droplets containing the sample are desolvated and migrate along the ion transfer tube under atmospheric pressure, entering the capillary at the front end of the mass spectrometer, and then detected by the detector of the mass spectrometer. "

"He really knows! Could it be that he really does research on DESI?" The female assistant researcher was shocked.

Others also looked at Zhang Wei in surprise. No one had heard of DESI, a newly invented new technology, but the Chinese exchange student in front of them could clearly explain its principles!
Only Huang Junji was unconvinced and continued to argue: "Even if you know the principle, you didn't do the experiment, so why do you say there is something wrong with the solvent?"

Xiao Xiba's face is itchy again, and she needs to be licked!
