The night outside the window gradually becomes darker, the lights in the distance are brighter, and the night view of the bustling metropolis is so beautiful that it is dazzling.

Qin Ke had no intention of appreciating it. He was still sitting at the desk, spinning his pen quickly on his fingers.

The pen body rotated back and forth at a dizzying speed, but Qin Ke's eyes were fixed on the dozens of pieces of draft paper placed in front of him, on which were drawn a twisted network of heterogeneous structures.

These are the structural shapes that Qin Ke drew based on his professional-level physical theory and a summary of all the experimental data at hand. He also deduced them one by one through mathematical models. The correct answer should be here.

But no matter which one it was, it always gave him an awkward feeling. There must be some small problem somewhere, but he was a fan of the authorities and couldn't find the problem for a while.

At this time, Ning Qingyun went to take a shower. Only Qin Ke and his sister Qin Xiaoke were in the study.

The little girl now basically leaves for the city to learn painting with Professor Mai around nine o'clock every day, and comes back around four in the afternoon. She is picked up and dropped off by the work assistant Fang Yongtang. It takes about an hour one way, which is quite hard, but Qin Xiaoke is very good.

He works surprisingly hard, never complains about hardship or tiredness, and even talks about interesting things about studying with Professor Mai during dinner every day.

I have to admit that although there is just an extra little girl, it does make the family a little more lively.

"Brother, haven't you thought of what's wrong?" The little girl put down a book of sketches to appreciate, and came over to pat Qin Ke's shoulders.

"Just a little bit, I need inspiration." Qin Ke put down the rotating pen a little tiredly, closed his eyes, and enjoyed his sister's rare well-behavedness.

It is now mid-July, and it has been almost three days since the final exam. Qin Kelian has temporarily put aside the mathematics topic "Hail Conjecture". Except for two or three hours a day of EDA topics, the rest of the time is devoted to "Relaxor Ferroelectric Thin Films"

"Improvement of Materials" topic, but there is always just a little bit of inspiration missing.

It's a pity that the system's "Inspiration Amplification" function has no sign of coming. It should be that there is insufficient time to study and the conditions for activation are not met. Qin Ke feels that it is useless to run long distances and vomit.

"Brother, these graphics you draw are so ugly."

"Yes, I haven't had any artistic talent since I was a child. My singing is out of tune, and my painting skills are about the same as those of children in kindergarten. You girl must have stolen all my artistic abilities." Qin Ke responded lazily, closing his eyes.

.

"Hey, it's okay. I can draw. Bro, whatever shape you want to draw, I'll help you draw it."

"I don't know what the exact shape is. Anyway, it's a mesh structure. It should be similar to one of the dozen or so paintings I drew."

Qin Xiaoke put away the little fist that was beating his shoulders, went over to pick up the dozen or so mesh structure diagrams and looked at them for a while, then jumped back to the lunch bed and picked up the brush: "Brother, let me try, you guys

There is a problem with the shape, that is, it is not aesthetically pleasing.”

Qin Ke was funny: "It's about aesthetics. This is drawn based on physical theory, not art theory..."

Halfway through his words, he suddenly paused.

Because he remembered the elective course "Art Appreciation" he took in the first semester of his freshman year. The teacher who taught the class at that time once said:

"Everything in the world, as long as it is correct, will give people beautiful visual effects. The composition of art also follows specific rules, such as using triangles to give the audience a stable impression, and using diagonal compositions to express positive and uplifting sentiments.

Tension... Let me explain the composition of these famous paintings. If you measure it carefully, you will find that their compositions all conform to the concept of the golden section, so they look particularly comfortable..."

Chewing this passage over and over, a thought flashed through Qin Ke's mind: "Does it look good because it conforms to mathematics? No...it looks good because it conforms to the truth and laws that exist in nature. Regardless of mathematics or

Physics abstracts truth from the laws of nature..."

The rustling sound in his ears made Qin Ke wake up from his thoughts. He saw Qin Xiaoke holding a paintbrush and sketching out beautiful lines. He quickly repainted Qin Ke's dozens of mesh structure diagrams.

Painted it again.

Unlike Qin Ke's ugly paintings, Qin Xiaoke optimized the lines and structure according to the art theory, making it look particularly pleasing to the eye.

Qin Ke vaguely felt that he had grasped something, and hurriedly said: "Little sister, show me all the paintings you have drawn."

"Hey, isn't the painting much prettier than yours?" Qin Xiaoke proudly handed over the painting folder.

"It's beautiful...it's really beautiful." Qin Ke opened the drawings one by one, but when he saw a certain picture, a light suddenly flashed in his mind. He pulled Qin Xiaoke and said, "Little sister, this one,

Can you help me draw it again? Can the spacing here be changed repeatedly from one large to one small, but still be able to draw an aesthetically pleasing painting?"

"One big and one small?" Qin Xiaoke took the pen and thought for a moment, then quickly drew a new one.

The more Qin Ke looked at it, the brighter his eyes became: "By the way, such repeated changes in spacing can regularize the formation of quantum wells, thereby limiting the possibility of minority carriers being captured by dangling bonds, thereby reducing the hydrogenation rate of subsequent dangling bonds.

Doesn’t it mean that the voltage loss can be reduced by improving it? I actually ignored this possibility, it’s really dark under the light!”

He rubbed Qin Xiaoke's long hair excitedly: "Thank you, little sister, you have been a big help this time!"

Qin Xiaoke blinked in confusion, not sure how she could help, but seeing her brother finally showing his usual confident smile, she became cheerful: "Hey, you're welcome, from now on."

You can come to me for any drawing matters."

"I must look for you!"

Qin Ke secretly admired it in his heart. Sure enough, the pursuit of truth in various disciplines in the world all lead to the same goal by different paths! This is the main reason why Teacher Jiang wants him and Ning Qingyun to take more elective courses to expand their thinking!

Qin Ke sat back at his desk. It only took him about ten minutes to perfect his mathematical model, compile it into a program through low light, and quickly complete the deduction. The deduction results made Qin Ke very excited. His brand-new network

The shape of the structure, combined with the thickness value of .613μm derived from Ning Qingyun’s mathematical model, can reduce the loss by 19%!

This chapter is not over yet, please click on the next page to continue reading the exciting content! There is only 1% left to pass the qualifying line!

This is basically the limit of the optimization of the preparation process of relaxor ferroelectric thin film materials. Even if such a perfect state cannot be achieved in real-life experiments, it is estimated that the loss can be reduced by about 18%.

For the rest, as long as you gain something from the second direction, that is, from "improvement by doping with special elements", you can easily meet the requirements for completing the problem!

Qin Xiaoke was sitting cross-legged on the bed during her lunch break. When she saw her elder brother standing by the window talking to someone from the research team on the phone, telling him about re-doing the experiment, the little girl's eyebrows furrowed quietly.

It feels so good to be able to help.

If I stay with brother and sister Ning from now on, no one will say that I am a drag, right?

…

The next day, good news came from Professor He’s laboratory. Under the 0.611μm, new mesh structure shape preparation process, the final results were excellent, with the loss reduced by 18.8%, only slightly inferior to Qin Ke’s

The mathematical model derivation results.

Huo Xinguang, who called, was so excited that his voice trembled: "Thank you, Qin Ke, Ning Qingyun. Now everyone in the research team is almost crying with joy. We are still a little bit short of success.

The dawn of the future! Whoever says computational materials science is useless in the future, we will be the first to fight with them!"

This engineering man who was usually not very good at talking actually said so much in one breath. Qin Ke even heard the applause and cheers coming from the other end of the phone and felt a special sense of accomplishment:

"Team Leader Huo, if you hadn't conducted experiments and theoretical deductions based on our mathematical model again and again, we wouldn't have been able to complete the optimization of the mathematical model in such a short period of time. There is still a little to go, let's work hard together!"

"Okay! Let's work hard in the second direction! I will send you the latest discussion materials on recent topics!"

A few minutes later, Qin Ke and Ning Qingyun received dozens of discussion papers, all of which were the theoretical derivation and discussion papers of Professor He and his research team in the direction of "improvement of doping special elements" in the past half month.

One hundred thousand words.

From these documents, it is not difficult to see that the entire research team is working hard day and night, just for the scientific research spirit of never giving up until the last moment.

Qin Ke and Ning Qingyun looked at each other, and they both had a spontaneous resonance, which is the resonance of scientific researchers.

"By the way, Jun'er, let me show you some news."

Qin Ke used his voice to control his laptop and opened a web page.

Ning Qingyun looked over curiously and saw a news article on a large domestic news website. The title of the news read "Flood disaster encounters roadblocks, "J-92 breakwater" plan has achieved miracles".

"The latest domestic development and launch of the 'J-92 breakwater' solution that can cope with harsh geological environments has been trialled in several provinces and promoted on a small scale. Under the protection of the 'J-92 breakwater', it was easy to encounter disasters as soon as summer entered.

More than 20 counties and districts affected by floods have successfully survived the flood season in June this year, without causing any reduction in food production, casualties, or economic losses. It is reported that this 'J-92 breakwater' plan was developed by Xia Ke Academy

The Institute of Fluid-Structure Interaction Mechanics took more than two years to develop, and it has the advantages of rapid construction, good stability, and ability to adapt to harsh geological environments..."

Ning Qingyun was surprised and delighted: "Isn't this the 'J-92 Breakwater' project that we participated in last time at Professor Duan's Institute? Has it been put into pilot application so soon?"

Qin Ke was also in a very happy mood. This kind of satisfaction that he saw that his scientific research results had played an important role and were applied to the national economy and people's livelihood, and successfully protected the people and property, was beyond words.

"Yes, it has been prepared for two years. It is just the last super large-scale actual test before it will be trialled and promoted. It is estimated that more counties and districts will use this plan next year, and even many sections of coastal protective embankments will adopt this method.

A plan.”

Romance

Ning Qingyun's beautiful eyes flashed with full pride: "I'm so happy, Qin Xiaoke, I feel that we are getting closer to the goal we set at the beginning."

"Well, it's a pity that this is not a large-scale topic that we are leading. Now that we have accumulated more experience, in a few years, there will always be a time when we personally preside over such a major topic!" Qin Ke pinched the girl's innocent and cute little blushing face: "Okay

Okay, let’s return to the topic at hand. I won’t mention EDA. Its significance is no worse than Professor Duan’s breakwater. If Professor He’s project succeeds, it will also have a profound impact on the energy storage industry.

It’s a small impact, so we have to work hard and strive to do our best!”

Ning Qingyun clenched her fists: "Okay, try to be the best!"

The two high-fived each other in tacit understanding and devoted themselves to the research of the project again.

In the past ten days, Qin Ke has completed the absorption of the "Computational Materials Science" and "Chemical Materials Science" parts of professional-level chemistry knowledge twice, and he has new ideas for this "improvement of doping special elements".

With new understanding and understanding, especially after carefully reading the latest information on this direction from the research group, Qin Ke even had a preliminary idea of ​​the direction with the highest success rate.

He wrote on the paper the chemical formulas of the six elements "phosphorus, boron, iron, bismuth, platinum, and titanium" and their oxides and hydrides.

Among them, "bismuth, platinum, and titanium" are the research results of the research team during this period. However, because they are rare metals, the cost of conducting an experiment is too high. It has only been tested once so far. Qin Ke needs to use experimental data and mathematical modeling to

Deducing which metal is the most suitable.

The first three were deduced by Qin Ke based on theory.

With a clear subdivision direction and certain experimental data, the next work will be much easier.

After imparting relevant knowledge to Ning Qingyun through "thinking resonance", Qin Ke arranged: "Jun'er, I am responsible for the modeling of oxides, and you are responsible for the modeling of hydrides, how about it?"
