I really just want to be a scholar

Computational materials science is a little more troublesome than Qin Ke imagined.

Different from the subject of computational fluid dynamics, because he has professional-level physics knowledge plus S-level knowledge "Exploration and Detailed Explanation of the Nonlinear Partial Differential Equation "Navier-Stokes Equation"" as the theoretical basis.

It is also different from the mathematical modeling of biological vaccine adjuvants, because it was supported by Grandma Chu Mimei's detailed papers, notes and rich experimental data back then.

This time Professor He's two subjects, Qin Ke faced relatively great difficulties, especially although his chemistry subject has been upgraded to the professional level, but the relevant knowledge has not had time to absorb, which is a typical "level has been raised but the strength is not enough". Keep up."

After pondering, Qin Ke decided to suspend the absorption of master-level mathematics knowledge first, and give priority to absorbing the theoretical knowledge of chemical materials and computational chemistry in the chemistry subject. It takes about [-] days to fully absorb it.

Therefore, Qin Ke decided to start with the subject of "improvement of relaxor ferroelectric thin film materials", which is more in the direction of physical materials. After all, his physics subjects have reached the real professional level, and he is proficient in all sub-subjects of physics. At the professional level, the level of any sub-subject will not be inferior to the top doctoral students in this field.

Professor He Liangfu has a high level of materials science and rich experience. After a detailed analysis based on his own theoretical knowledge, Qin Ke believes that Professor He's "attempt to adjust the thickness and shape of the relaxor ferroelectric thin film" and "towards the relaxation of iron Doping new materials in the electrical thin film should be feasible, but it is very difficult to implement, too many attempts are required, too much money is spent, and neither time nor funds are enough.

The most feasible way is to predict the scheme with the highest success rate through computational materials science, and then confirm it by doing experiments.

The premise is to be able to establish a mathematical model.

Qin Ke decided to take time to go to the laboratory with Ning Qingyun to do the experiment of "improvement of relaxor ferroelectric thin film materials" with Huo Guangxin, a postdoctoral fellow, to really master the experimental skills and understand how each piece of data is obtained. In order to facilitate subsequent mathematical modeling.

The next day happened to be the weekend, and Qin Ke pulled Ning Qingyun to go to Lao He's laboratory, but Qin Xiaoke was bored at home all day, and followed him pitifully, wanting to talk but not daring, Ning Qingyun couldn't see After going down, he said that he would take Qin Xiaoke with him.

After the wife spoke, Qin Ke had no choice but to take the oil bottle with him.

"Sister Ning, let's go, I will be very good, and I will not talk wildly when I arrive in the laboratory. I will watch beside you and experience the atmosphere of a scientific worker!" Qin Xiaoke hugged Ning very excitedly Qingyun's hand ignored Qin Ke's stern face at all.

Qin Ke gritted his teeth with hatred.

He finally found out that it was a wrong decision to bring Qin Xiaoke to the capital. Ning Qingyun was so tender-skinned that he was too embarrassed to be too close to Qin Xiaoke, let alone sleep in the master bedroom together at night.So last night, she also slept with Qin Xiaoke on the first floor, leaving Qin Ke to go back to the master bedroom on the second floor alone, feeling lonely and cold all night.

Why don't we just throw Qin Xiaoke out to learn how to draw?
Thinking in his mind, Qin Ke unknowingly drove to the downstairs of the laboratory building of the School of Materials Science and Technology.

After parking the car and showing the passport given by Professor He, Qin Ke successfully took the two girls into the laboratory of the research group "Improvement of Relaxor Ferroelectric Thin Film Materials".

Professor He was discussing the next direction with more than a dozen members of the research group including Huo Guangxin. When he saw Qin Ke and Ning Qingyun coming, he naturally stopped.

After asking clearly about the purpose of coming, Lao He said: "Go, I will take you to do the experiment myself."

Regarding Qin Xiaoke, who put on a big white coat and took a few beautiful selfies, and then looked around curiously, everyone just showed a tolerant smile. After all, this little girl is still very good-looking, and It's Qin Ke's younger sister, even if it's from Qin Ke's face, she will treat this little girl differently.

"This is a high-resolution transmission electron microscope, which is mainly used for microstructure analysis inside materials and quantitative analysis of micro-region components." Professor He explained the experimental equipment to Qin and Ke one by one, and taught them how to operate.

Professor He's laboratory is indeed well-equipped, and there are more than a dozen types of equipment for material analysis alone.

Not to mention thermal analyzers, common TG, DTA, DSC, DMA, TMA are all neatly placed in the laboratory.

In addition, there are electron probe microanalyzers (used for high-speed qualitative or quantitative analysis of micron-level and sub-micron-level chemical compositions on the surface of materials), thermal dilatometers (used to accurately measure linear thermal expansion, thermal expansion of materials during heat treatment coefficient, softening coefficient), Fourier transform infrared spectrometer (for the composition and qualitative and quantitative analysis of organic matter), laser Raman spectrometer (for analyzing the spectrum of material components, structures, etc.), etc.

Even the expensive Inductively Coupled Plasma-Atomic Emission Spectrometer (ICP-OES) has it!

ICP-OES is a high-precision instrument, which can be used for qualitative, semi-quantitative and precise quantitative analysis of elements, and can also determine the content of elements. This equipment is rare in China, and it is great to have one in ordinary colleges and universities.

Kiyoki University is worthy of being a top engineering school, and it can be found in the laboratory of a professor of materials science.

These devices made Qin Ke salivate. Unfortunately, he tried to project these personally operated devices into the virtual scientific research experiment center, but the system indicated that the "Material Technology" laboratory was not open and could not complete the projection, which made Qin Ke The original plan to repeat the experiment at no cost through the virtual scientific research experiment center fell through.

That being the case, let's try to solve the problem in computational materials science!
Qin Ke and Ning Qingyun spent the whole day in the laboratory learning various experimental operations.

With Qin Ke's talent in science, which is almost the best in the world at this time, he can basically master it by operating the experimental equipment once, and then he assisted Professor He to guide Ning Qingyun. "Thinking resonance" once again played a great role, making Ning Qingyun also knew the whole set of experimental procedures like the palm of his hand.

At the end of the day's experimental study, both of them felt that they had learned a lot, especially the careful Ning Qingyun, who wrote more than ten pages of notes.

It wasn't until night fell that the three left Professor He's laboratory, and Professor He and the others had to stay and continue to discuss and research theoretically. They didn't pin all their hopes on Qin Ke and Ning Qingyun, and they still relied on With professional knowledge tirelessly in-depth discussion, in order to break through the difficulties.

Qin Xiaoke twitched his tongue: "It's hard work to do scientific research. I think everyone is busy looking for information, writing calculations, or discussing repeatedly, except for a short break at lunch. "

The little girl did well today, she actually knew how to take the initiative to help distribute the boxed lunches, she even helped to clean up after eating, collected the garbage and threw it away, and she didn't make any noise or disturb others all day long, just be quiet She quietly followed Qin Ke and Ning Qingyun, and occasionally helped pour tea and water, like a qualified little follower, so that the brothers and sisters in the laboratory praised her unanimously, saying "Qin Ke, your sister So obedient, so cute", Qin Ke was inexplicably a little bit refreshed.

At this time, Qin Ke saw his sister bring up this topic, so he seized the opportunity to educate her: "Now you know that work is not easy? So you have to learn your skills..."

Qin Xiaoke curled her lips: "Then work as hard as them? I might as well learn to draw, at least drawing is easy and happy."

Qin Ke: "..."

What this little girl said was so reasonable that he couldn't find a reason to refute it.

However, Qin Xiaoke didn't say anything like "Brother Lai will live his whole life, eat, wear and spend his whole life without going to work or work" like he did when he was a child, so he has made progress after all.

Qin Xiaoke glanced at Ning Qingyun who was next to her, and suddenly pulled Qin Ke aside, whispered furtively: "Brother, I will quietly half-wet my bed tonight, and then Sister Ning can only go to your room I'm asleep, it's a chance for you to eat her, how about it? Also, I've tried it for the past two nights. Although Sister Ning is a bit shy, she seems to understand everything she needs to know. You have to be decisive and strong. Don't let her escape. As a younger sister, I can only help you so far!"

Qin Ke: "..."

Although he had eaten the cabbage a long time ago, Qin Ke was very grateful for his sister's painstaking efforts.Well, Qin Xiaoke, I wrongly blamed you earlier, it turns out that you have been pestering Ning Qingyun for the past two days to spy on information.Hmm... Although you are such a big kid, it's just that I, a brother, feel a little complicated.

Seeing that Qin Ke didn't speak, Qin Xiaoke was dissatisfied: "Brother, why aren't you moved? Why do you think I must follow me all the way to the capital? Isn't it because of you, brother? Otherwise, sister Yining is so shy Personality, brother, you haven't had a chance to succeed in several years!"

But I already succeeded Roar, Qin Ke said perfunctorily: "Okay, thank you."

"Thank you verbally is not sincere enough." Qin Xiaoke crossed his waist, his eyes full of pride: "So, brother, I want to have a big meal tonight, and I don't want to get up early every morning to make breakfast, you Help me prepare! You still have to take time to take me and Sister Ning to play around the capital, so that I can give you assists every day, so that you can continue to unlock Sister Ning's new CG!"

Also unlock new CG, do you think it is playing a game!
It's confirmed, [-]% of this stinky girl betrayed Ning Qingyun for the sake of eating, drinking and having fun, not for the sake of my brother's happiness at all!
But Qin Ke rubbed his chin to unlock Xiaobaicai's new pose... Oh no, the new CG seems like a good idea.

Qin Ke said seriously: "You actually want to seduce me with such a condition, do you think your brother is such a superficial person?"

Qin Xiaoke said: "Of course not, my brother is the most upright gentleman, we just cooperate to unlock beautiful pictures."

"Oh, it's not impossible to think about unlocking a beautiful picture."

"Yeah! Sister Ning, brother promised to take us to a big meal!"

……

After all, Qin Ke took the two girls to have a luxurious western meal. First, it was a welcome banquet for Qin Xiaoke to clean up the dust, and second, it was because Qin Ke remembered that he hadn't gone out with Ning Qingyun for a long time to enjoy life. up.

No matter how busy you are in studying and scientific research, you can't ignore the rhythm and happiness that life itself should have, can't you?

It's definitely not to let Qin Xiaoke assist and constantly unlock Ning Qingyun's new CG.
