I really just want to be a scholar

If you study chemistry well, you should be a chemist.If you are good at physics, then go to theoretical physics.If you are good at mathematics, wouldn’t it be more profitable to engage in finance?As for learning computers well, you can also make a lot of money by being a code farmer...

As for being proficient in the four major disciplines at the same time?That must be a top academic god, where can't you make a lot of money, and even engage in P's computational materials science!

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

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

Unexpectedly, the two well-known mathematical geniuses in the rumors in front of them were fooled and plunged into the "big pit" of computational materials science. Everyone didn't know whether to say that they were formidable young people, or they didn't know the heights of heaven and earth.

Seeing everyone's expressions, Professor He Liangfu was a little bit uneasy:
"Why do you have the expression that I pushed Qin Ke and Ning Qingyun into the 'fire pit'? You don't want to learn, or you can't learn computational materials, it doesn't mean that Qin Ke and Ning Qingyun can't do it! They are calculating fluid I have rich experience in mechanics and computational biology, and I also have strong computer skills. This time, our two projects have been stuck in difficulties for nearly a month without any progress. Maybe we will rely on their computational materials science to achieve new results. breakthrough."

It was only then that everyone remembered that besides being mathematical geniuses, the two students in front of them had indeed developed an operating system before, and at the beginning of the year, they had also used mathematical modeling to uncover the truth about the fraudulent thesis of a master of biology. Their achievements in mathematics are so dazzling that people ignore their other "deeds" in the past.

Tian Tianjiao was the first to react, and said with an apologetic smile: "Yes, our boss has always had a unique vision. I must have seen that you have talents in this area. Speaking of which, you are good at mathematical modeling and computer programming. You only need to add some chemical and physical materials. knowledge, you will definitely be able to easily master computational materials science.”

The rest of the people also responded one after another, but this group of scientific researchers are not good at acting on the spot, and their attitude is extremely unnatural, and anyone with a discerning eye can see that they are not sincere.

Professor He Liangfu sighed helplessly, turned his head and laughed at Qin Ke and the two of them: "Qin Ke, Ning Qingyun, you two have to fight back for me, or I, a bad boss who is a 'student' Fame can’t be shaken off. I’m really optimistic about the direction of computational materials science, but I’m not capable enough to keep up with the international level, and the group of guys I lead don’t have the slightest ambition to delve into this direction.”

Qin Ke blinked, patted his chest deliberately and said, "Professor He, don't worry, we will work hard to learn computational materials well, even if you cheat us, we will not speak ill of you everywhere."

Professor He Liangfu pointed at Qin Ke: "You kid, play backstab for me..." He laughed out loud in the middle of speaking.

Everyone also laughed loudly, and the relationship with Qin Ke and the two also became much closer in this laughter.

"Let's go, show you our experimental equipment, take a step back, even if you don't have any great experience in computational materials science, since you come to my laboratory, you will gain something." He Ren is still good, he is the kind of boss who can joke and do scientific research, and immediately brought Qin Ke into the laboratory.

Unlike the research groups in the physics laboratory, almost all the people in the material laboratory wore white coats, which looked like a scientific research experiment. Qin Ke and Ning Qingyun were also assigned a white coat, and put on a white coat. Immediately afterwards, there was a little excitement of "full sense of ritual", and I couldn't help but smile at each other.

The first one to enter was the laboratory of the research group of "Carbon Nanotube Fiber Coating Research". Professor He Liangfu signaled Tian Tianjiao to continue the experiment, and he explained the details to Qin and Ke.

"You should have read the subject materials, right? Carbon nanotubes are popular materials used in many cutting-edge fields. They are characterized by low density, high strength, high toughness, high flexibility, high electrical conductivity, low thermal expansion coefficient, 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 experiment that the graduate students were doing, and continued: "Look, the current research we are doing mainly uses atomic layer deposition technology to coat the surface of carbon nanotube fibers with a dense coating to improve their durability. And flame resistance. We have tried common inorganic oxides such as zinc peroxide, magnesium oxide, and silicon oxide, but they have failed to form a good adhesion effect and thin film interference effect, and we are currently stuck in the research and development of this coating material. "

He sighed: "There are too many inorganic oxides, and our scientific research funding and subject time limit do not support unlimited repeated experiments, so we can only try to see if we can find the most suitable inorganic oxides through computational materials science. Before I have sent you hundreds of experimental data and the theoretical knowledge involved, but it is recommended that you do it a few times in person, so that you should be more aware of how each row of data comes from, which will help you follow up with mathematical modeling .Tomorrow, if you have time, come to Tian Tianjiao, she will personally guide you to do the experiment."

After 15 minutes of explanation in the laboratory of the research group of "coating research on carbon nanotube fibers", Lao He took Qin Ke and the two to the laboratory of the research group of "improvement of relaxor ferroelectric thin film materials", and also made a detailed explanation on-site explanation.

Unlike the previous subject, which belongs to the direction of chemical materials, this subject is closer to the direction of physical materials.Relaxor ferroelectric thin film materials have a nano-ferroelectric domain structure, which is one of the most potential energy storage materials at present. The energy storage density and energy storage efficiency are quite good, but the loss caused by the domain flip energy barrier has become a roadblock. The energy storage density is stuck at 90J/cm3, and the energy storage efficiency is stuck at 60%, which cannot be further improved...

"There are two ideas we have come up with 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. Through the local chemical structure and electrical heterogeneity Change, to reduce the domain switching energy barrier loss..."

"The data given to you is the second-order nonlinear optical detection data obtained through the WITec confocal microscopy imaging system, as well as the data observed by the high-resolution scanning transmission electron microscope. Our achievements in these two directions are not significant. Neither the electrical domain structure nor the interdomain coupling changes significantly in the unit cell size."

After introducing the actual situation of the two subjects, Lao He brought the two of them to his office, served tea, and said in a low voice: "Currently we don't have enough funds for this subject, and the most important thing is that the deadline is only There are about two months left, and it has already been postponed once, so we can no longer apply for an extension. If this problem is still not resolved before the end of August, the project can only be declared a failure.”

Hearing Lao He's heavy tone and looking at his bitter expression, Qin Ke and the two finally realized why Professor He Liangfu came to beg them. In fact, the direction of computational materials science can almost be said to be the most cost-effective method at present. Well, Lao He is treating a dead horse like a living horse, and treating the two of them as life-saving straws.

Because of the failure of the scientific research project, the main person in charge has to bear the responsibility, ranging from being disqualified from applying for the project in the second year, to being unable to apply for project funding within three years.

These two of Lao He's two are national key projects, and the consequences of project failure must be serious, and the outcome of being unable to apply for project funding within three years is almost impossible to escape.

Without a subject, there would be no resources, and even the salary of a graduate student would not be paid, let alone write a thesis to form scientific research results to meet the school's assessment. After three years, he might lose his doctoral supervisor qualifications.

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

How many three years are there in life?Not to mention his three years in the golden age of scientific research.

Lao He sighed: "I also know that it is difficult to find a solution to these two subjects before the end of August, but even if one subject can be completed, the laboratory can be regarded as an explanation to the above, and it can win more time for another subject. So, Qin Ke, Ning Qingyun, I will try my best to try various methods here, and please pay more attention, just choose any topic you are sure about, and see if you can help solve it through mathematical models Difficulties? I will let the two research groups cooperate with you as much as possible, and I can also personally guide you to do various experiments with equipment."

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

Professor He thanked them again and again. Seeing that the class was about to start in the afternoon, he personally sent the two of them out of the laboratory.

The two had just discussed in low voices when Qin Ke's cell phone rang, and it was an acquaintance Professor Hu Qingfeng calling.

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

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

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

Qin Ke looked up, and sure enough, he 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 can be regarded as alumni and old friends. The difficulties he encountered this time are really troublesome. I recommended you two to him."

Old Hu said with a sigh: "To be honest, when he took these two national projects last year, I didn't agree with them. These two projects are hard bones, and the time is short, so it's not easy to chew. But Lao He was at home at the time. Something happened. My son was deceived while studying abroad, and owed a large amount of debt. The creditor came to the door. He gritted his teeth and sold all the house and car. He almost went bankrupt and failed to make up for the hole... …And if these two projects are successful, he will have a large bonus, and he will be able to pay off all the debts by then, so he insisted on taking it."

"Old He is a really good character. There are tens of millions of scientific research funds for these two projects. He insisted that he didn't embezzle a penny, and used all of them for experiments. The person in charge of auditing scientific research funds just came here this month. He also sighed, "Professor He's use of funds is exemplary." In short, if you can really help him, please help him. If you need my assistance, you can just ask for money. As long as you open your mouth, I will try to satisfy you."

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

Thinking of Professor He's 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 both told Professor He just now. After that, since we joined the research group, we will go all out to solve the difficulties together!"
