If you are good at chemistry, you can become a chemist. If you are good at physics, you can pursue theoretical physics. If you are good at mathematics, why not make more money by engaging in finance? As for if you are good at computers, you can also make a lot of money as a coder...

…

As for being proficient in four major subjects at the same time? He must be a top scholar. Where can he not make a lot of money, he can also engage in computational materials science of P!

Because of the above reasons, it is difficult for computational materials science to develop. It only exists in books and plays a simple experimental auxiliary role.

Not only computational materials science, but also computational physics, computational chemistry, and computational biology all face similar dilemmas.

Unexpectedly, the two rumored mathematical geniuses in front of them were deceived and plunged into the "big pit" of computational materials science. No one knew whether to say that they were feared young people or that they didn't know what the world was like.

Looking at everyone's expressions, Professor He Liangfu felt a little confused:

"Why do you look like I'm pushing Qin Ke and Ning Qingyun into the 'fire pit'? Just because you don't want to learn, or can't learn computational materials science, doesn't mean that Qin Ke and Ning Qingyun can't do it! They are calculating fluids

They have rich experience in mechanics and computational biology, and they also have strong computer skills. This time our two projects have been stuck in difficulties for nearly a month without any progress. We may have to rely on their computational materials science to achieve new results.

breakthrough."

Only then did everyone remember that in addition to being mathematical geniuses, the two students in front of them had indeed developed an operating system before. At the beginning of the year, they also used mathematical modeling to uncover the truth about a biology master's paper fraud.

Their achievements in mathematics were so dazzling that people ignored their other past "deeds."

Tian Tianjiao was the first to react, and said with a smile: "Yes, our boss has always had a unique vision, and he must have seen that you have talents in this area. It is said that you are good at mathematical modeling and computer programming, as long as you add some chemical physics materials

If you have enough knowledge, you will definitely be able to easily master computational materials science.”

The rest of the group also responded, but this group of scientific researchers were not good at playing tricks on the spot, and their attitude was extremely unnatural, and anyone with a discerning eye could see that they did not mean what they said.

Professor He Liangfu sighed helplessly, turned to Qin Ke and laughed at himself: "Qin Ke, Ning Qingyun, you two have to fight for this breath for me, otherwise I am a bad boss who 'tricks students'

I can’t shake off my reputation. I am indeed very optimistic about the direction of computational materials science, but my ability is not good enough to keep up with the international level, and the guys I lead have no ambition at all and are unwilling to delve into this direction.”

Qin Ke blinked and deliberately patted his chest and said: "Professor He, don't worry, we will work hard to learn computational materials well. Even if you cheat us, we won't say bad things about you everywhere."

Professor He Liangfu pointed at Qin Ke: "You kid, try to stab me in the back..." He laughed out loud in the middle of the sentence.

Everyone also burst into laughter, and their relationship with Qin Ke became much closer amidst the laughter.

"Let's take a walk and show you our experimental equipment. To say the least, even if you don't have any great experience in computational materials science, you will have gained something since you came to my laboratory."

He Ren was pretty good, the kind of boss who could joke around and do scientific research in a down-to-earth manner. He immediately brought Qin Ke and the two of them into the laboratory.

"First Evolution"

Different from the research group in the physics laboratory, almost all the people in the materials laboratory are wearing white coats, which looks like a scientific research experiment. Qin Ke and Ning Qingyun were also assigned a white coat each and put them on.

After that, I suddenly felt a little excitement with a "full sense of ritual", and I couldn't help but look at each other and smile.

The first person to enter was the "Coating Research on Carbon Nanotube Fibers" research group laboratory. Professor He Liangfu motioned to Tian Tianjiao to continue the experiment, while he explained the details to Qin Ke and Qin Ke.

"You must have read the subject materials, right? Carbon nanotubes are a popular material used in many frontier fields. They are characterized by low density, high strength, high toughness, high flexibility, high conductivity, low thermal expansion coefficient, and corrosion resistance.

Impact fatigue resistance, heat resistance, etc., have great potential in superconducting fibers, carbon-based chip manufacturing, flexible fiber electrodes, and smart wear."

Lao He pointed to the experiments being done by the graduate students and continued: "Look, the current research we are doing is mainly to use atomic layer deposition technology to coat the surface of carbon nanotube fibers with a dense coating to improve its durability.

and flame resistance. We have tried common inorganic oxides such as zinc oxide, magnesium oxide, and silicon oxide, but they have failed to form a good adhesion effect and thin film interference effect. We are currently stuck in the research and development of this coating material.

"

He sighed: "There are too many inorganic oxides. Our scientific research funds and project time limits do not support unlimited repeated experiments, so we can only try to see if we can find the most suitable inorganic oxide through computational materials science. Before

I have sent you hundreds of experimental data and the theoretical knowledge involved, but I suggest you do it yourself a few times. This will give you a clearer understanding of where each row of data comes from, which will help you with subsequent mathematical modeling.

.If you have time tomorrow, come see Tian Tianjiao, and she will personally guide you in doing experiments."

After explaining for fifteen minutes in the laboratory of the "Coating Research on Carbon Nanotube Fibers" research group, Lao He took Qin Ke and the two of them to the laboratory of the "Improvement of Relaxor Ferroelectric Thin Film Materials" research group and gave the same lecture

Detailed on-site explanation.

Unlike the previous topic, which was in the direction of chemical materials, this topic is closer to the direction of physical materials. Relaxor ferroelectric thin film materials have nano-ferroelectric domain structures and are currently one of the most promising energy storage materials. The energy storage density and

The energy storage efficiency is quite good, but the loss caused by the electrical domain flipping energy barrier has become a stumbling block, causing the energy storage density to be stuck and the energy storage efficiency to be stuck at 60%, unable to be further improved...

This chapter is not over yet, please click on the next page to continue reading! "We have two ideas now. One is to try to adjust the thickness of the relaxor ferroelectric film, and the other is to dope new materials into the relaxor ferroelectric film.

Materials reduce the electrical domain flipping barrier loss through changes in local chemical structure and electrical heterogeneity..."

"The data given to you is the second-order nonlinear optical detection data obtained through the WITec confocal microscopy imaging system, and the data observed by high-resolution scanning transmission electron microscopy. Our results in these two directions are not significant.

, the electric domain structure and inter-domain coupling of the unit cell size have not changed significantly."

After introducing the actual situation of the two projects, Lao He brought the two of them to his office, gave them tea, and then said in a low voice: "Currently, we don't have enough funds for this project. The most important thing is that we are only 10 years away from the deadline.

There are about two months left, and it has already been extended once. You cannot apply for another extension. If you still cannot solve this problem before the end of August, you can only declare the project failed."

Hearing Lao He's heavy tone and looking at his bitter look, Qin Ke and Qin Ke realized why Professor He Liangfu came to beg them. In fact, the direction of computational materials science can be said to be the most cost-effective method at present.

Okay, Lao He is treating a dead horse like a living horse and treating these two people as life-saving straw.

Because the scientific research project fails, the main person in charge must bear the responsibility. At least, he will be disqualified from applying for the project in the second year, and at worst, he will not be able to apply for project funding within three years.

Both of Lao He's projects are national-level key projects. The consequences of project failure will definitely be serious. The outcome of being unable to apply for project funding within three years is almost inevitable.

Without a project, there are no resources. He can't even pay a graduate student's salary, let alone write a thesis to form scientific research results to meet the school's assessment. After three years, he may lose his doctoral supervisor qualifications.

For Lao He, this is a major event related to future career development.

How many three years are there in a life? Let alone the three years in his golden age of scientific research.

Lao He sighed: "I also know that it is difficult to find a way to solve these two topics before the end of August, but even if one topic can be completed, the laboratory has an explanation to the above and can get more time for the other topic.

.So, Qin Ke and Ning Qingyun, I will try my best to try various methods. I also ask you to pay more attention and choose any topic that you are confident about and see if you can help solve it through mathematical models.

Difficulties? I will ask the two research groups to cooperate with you as much as possible, and I can also personally guide you in using the equipment to conduct various experiments."

Qin Ke and Ning Qingyun looked at each other and said solemnly: "Professor He, don't worry, since we have joined the research team, we will definitely do our best."

Professor He thanked them again and again, and seeing that class was about to begin in the afternoon, he personally escorted the two of them out of the laboratory.

The two of them had just discussed in a low voice when Qin Ke's cell phone rang. It was a call from an acquaintance, Professor Hu Qingfeng.

"Qin Ke, you just left Lao He's laboratory?

"Professor Hu, do you have good ears or clairvoyance?"

"No, if you look up, you can see me."

Qin Ke looked up and saw Lao Hu standing in the corridor on the third floor of the physics laboratory building, waving his hand.

"Qin Ke, Lao He and I are alumni and old friends. The difficulties he encountered this time are indeed more troublesome. It was I who recommended you two to him."

Lao Hu sighed with regret: "To be honest, when he took on these two national-level projects last year, I didn't agree with them. These two projects are hard-core, and the time is short, so they are not easy to deal with. But Lao He was at home at the time.

Something happened. His son was defrauded while studying abroad and owed a large amount of debt. The creditor came to the door. He gritted his teeth and sold all the houses and cars. He almost lost his entire family and could not fully make up for the hole...

...If these two projects are successful, he will receive a large bonus and all the debts will be paid off, so he just took it."

"Lao He is a really good person. There are tens of millions of scientific research funds for these two projects. He did not misappropriate a penny and used them all for experiments. The person responsible for auditing scientific research funds just came here earlier this month.

He also sighed, "Professor He's use of funds is exemplary." In short, if you can really help him, please help him more. If you need my help, just ask for help.

As long as you open your mouth, I will find a way to satisfy you."

Only then did Qin Ke know that there was such an inside story.

Thinking of Lao He's somewhat gray hair, the tiredness on his face, and his patience when explaining to the two of them, Qin Ke nodded without hesitation and said: "Professor Hu, don't worry, we just told Professor He

After passing it, now that we have joined the research team, we will go all out to solve the difficulties together!"
