The top student must be diligent

Are you kidding?

Of course, let's not talk about this for now. What shocked them even more was that Xiao Yi actually came to the conclusion earlier than their senior sister?

Although it was only one or two seconds earlier...

But this was beyond their imagination.

Their invincible senior sister was actually slightly inferior? !

Xiao Yi could figure out these things just by his mathematical ability?

They began to feel a little confused.

"Then what do you think these things should represent?"

Not knowing what the rookies behind him were thinking, Luo Mingya asked Xiao Yi with great interest.

No matter how good you are at math, you can't answer all these questions, right?

Of course, Xiao Yi really couldn't give an accurate answer, but he thought about it a little bit based on some possible ideas and said, "It should represent that the internal units of this abnormal sample are different? Hmm... I have heard that there is something called lattice in the unit of materials. Maybe it is related to this?"

When Xiao Yi said the word lattice, Luo Mingya finally showed surprise in her eyes.

After taking a deep look at the mathematical genius, she said, "You have guessed it almost right. My inference is that these abnormal peaks may be related to lattice defects or dislocations in metal alloys."

Xiao Yi's eyes lit up: "It seems that I really guessed it right."

Luo Mingya didn't say much, turned to the junior brothers and sisters behind him and said, "I hope this case can give you some experience. For this kind of curve, we obviously have to think of using Fourier transform and spectrum analysis to study it."

"Especially Zhao Yuanyuan, this data is already very obvious. If you don't see it, it means that you don't practice enough. I will find five more papers for you to read later."

Zhao Yuanyuan: "Ah?"

"The next step is to use material microscopes and X-ray diffraction experiments for further research."

"Go back to the laboratory to work."

Under Luo Mingya's command, no matter how much Zhao Yuanyuan wanted to cry, she could only quickly return to the laboratory and start research.

Xiao Yi didn't know how to use it, so he just watched them use it.

Xu Ming and Liu Chao were idle, standing aside, looking at Xiao Yi, and then asked: "That... Brother Xiao, how did you see it just now?"

"I saw it just like that." Xiao Yi said: "Probably... find the difference?"

Find the difference!

(╯‵□′)╯︵┻━┻

Xu Ming and Liu Chao were embarrassed.

Liu Chao asked again: "Then... how did you think of the lattice? Have you really never studied materials?"

Xiao Yi said: "I really haven't studied it. As I said just now, I just heard about the concept of lattice by chance, so I remembered it. As for why I can guess it... To use a uh, more distorted word, it can probably be understood as calculus, which continuously divides the entire metal block into the smallest units, and the abnormal peak is almost equivalent to an abnormality in the smallest unit of calculus. Well, naturally it is related to the lattice."

Xu Ming, Liu Chao: "..."

This is the mathematical thinking of the god level ?

Xu Ming thought for a while, and suddenly his eyes lit up, and he said: "Then Brother Xiao, I recently saw a question on the Internet, proving that the cube of π is greater than 31. If you were to do it, Brother Xiao..."

Before he finished speaking, Xiao Yi replied: "It is easy to observe that the cube of 3.1415 is approximately equal to 31.0035, which is greater than 31."

The two were stunned. This can also be observed?

3.1415 multiplied by 3.1415 multiplied by 3.1415...

What a joke!

"Brother, try another method. We can't do this mental arithmetic in our minds."

"Well..." Xiao Yi said: "Okay."

Then he took out a small notebook and pen from his pocket, and wrote on it :

"Well, that's it."

After Xiao Yi finished writing the formula, he tore off the paper and handed it to them.

After reading it, Xu Ming and Liu Chao were silent.

They realized that they shouldn't have nothing to do and come to Xiao Yi to do this kind of problem.

Isn't this just asking for trouble?

"I say you guys are done, taking this kind of problem to Xiao Shen to solve, are you looking down on Xiao Shen?"

At this time, Zhao Yuanyuan came over, and her expression was very happy: "Senior sister has come to a conclusion, and it is basically certain that it is a lattice defect problem."

"Senior sister also said that as long as we conduct further research on this problem and put forward some understanding of the mechanical behavior of metals, or It is an optimization and improvement plan, maybe it can be released to the first zone at that time! "

"Thank you, Master Xiao! You have helped me a lot!"

Zhao Yuanyuan bowed 90 degrees to Xiao Yi.

Xiao Yi waved his hand quickly: "No need to thank me, I just provided some mathematical help, the most important thing is that your senior sister saw the problem."

"You found the problem first!" Zhao Yuanyuan looked at Xiao Yi with admiration: "Anyway, I will treat you to milk tea, and treat you to a meal next time!"

"Ah, no need for a meal." Xiao Yi waved his hand: "Milk tea is fine."

"Well, okay!" Zhao Yuanyuan had no choice but to nod, and then she took out her mobile phone and started to order milk tea.

"Hey? Where are ours?" Xu Ming next to him winked and said, "After all, we have been fellow students for such a long time, and we entered in the same year."

Zhao Yuanyuan glared at him: "Have you ever helped me?! Get out!"

"Oh no, Junior Brother Liu, we are outsiders now, your Senior Sister Yuanyuan..."

"Pia!"

A slap came from behind Xu Ming's head.

"What are you talking about here?" Luo Mingya slapped Xu Ming aside.

Xu Ming covered his head, widened his eyes, and looked at their senior sister in anger.

Liu Chao next to him quickly hid aside, indicating that it had nothing to do with him.

Luo Mingya clapped his hands, then looked at Xiao Yi and said, "Junior Brother Xiao, it seems that with your ability, you can now officially enter our topic."

"The purpose of our topic is to use density functional theory and first principles calculations to study the properties of defects in two-dimensional materials."

"If there is no problem, it is not a big problem to publish an NM or something."

Chapter 139 You still say you know a little?

"Two-dimensional materials of the transition metal dichalcogenide family are also well-known in our materials industry due to their wide tunability of electronic and optical properties."

In a conference room of the School of Materials, Luo Mingya stood on the podium and wrote the three words TMD.

At this time, she was introducing their topic to Xiao Yi in the audience.

Although Xiao Yi didn't understand, it didn't prevent him from giving him some concepts in this way to help him understand the purpose of the topic later.

And Xu Ming and his friends also came and were sitting below listening.

Of course, their mentor, Sun Lina, was also included.

After all, Sun Lina was the person in charge of this topic, and the project funds were all applied for in her name.

Now Xiao Yi has also learned from Xu Ming and his friends how powerful Sun Lina was when she was young.

Almost the same as Luo Mingya standing above, she entered the junior class at the age of 15, and then she completed her undergraduate studies in just three years, so she entered graduate school at the age of 18, the same as Luo Mingya. She completed her doctorate at MIT in four years, studied abroad for almost eight years, and then suddenly returned to China.

According to the gossip provided by Xu Ming, she suffered a blow in her relationship, so she chose to return to China. Of course, she had been selected as a Thousand Youths before returning to China, and became an Outstanding Youth after returning to China. The various funds added up to more than 10 million yuan each year.

She didn't give up completely. Occasionally, if there was a really good direction, she would take action. After returning to China, she had already won a second prize in the National Natural Science Award and two top journals.

Basically, the status of their laboratory, thanks to Sun Lina, is the best in their Institute of Materials, even those academicians' laboratories are not much behind.

However, when she gave up, she really gave up.

Xiao Yi and the others all looked back and saw Professor Sun sitting at the back, holding her switch and wearing headphones while having a picnic.

Then, according to Luo Mingya's temper...

"Sun Lina! If you don't want to listen, don't come here."

As expected, Luo Mingya glared at him immediately.

At this time, Sun Lina looked up at Luo Mingya, waved her hand and said, "Don't bother me. Even though I'm playing games, I can actually hear what you are talking about. Doing two things at the same time, don't you know?"

Luo Mingya: "Sooner or later, I will have to complain to the dean about your terrible mentor."

Sun Lina: "It's okay. This year, there are about a dozen companies that are preparing to hold recruitment fairs in our school for my sake. There are domestic companies such as Linde, Diaby, and Warwick, as well as a bunch of foreign companies. This year's spring recruitment can help our college relieve a lot of employment pressure, so the dean won't bother me."

Luo Mingya raised her eyebrows and said, "Very good, since you have such a big face, it seems that I can go to Warwick to ask how the seven-digit servers are sold, and maybe I can get a discount."

"Just buy it, so much funding..."

Sun Lina paused suddenly: "How many digits did you say?"

"Not much, our funding is eight digits, I'll buy a seven-digit one."

"Stop, my little ancestor, please don't ask."
