Chapter 338: Breakthrough in Superconducting Materials

With the optimized mathematical model, Xu Chuan found Gao Hongming, who was assigned by the Department of Science and Technology to be in charge of the overall work, and explained his purpose.

"No problem, I will report it to the higher-ups right away."

"But do you have any requirements for the supercomputing center you applied for in terms of performance?"

Hearing that it was to test the mathematical model of plasma turbulence, Gao Hongming quickly agreed and asked about the requirements.

Xu Chuan smiled and took out a card from the backpack behind him, handed it over, and said, "The performance requirements are all above. As for the time, the sooner the better. I'm sorry to bother you, Mr. Gao."

"No, no, no, Academician Xu, please don't say that. It is my responsibility to cooperate with your work and ensure your needs. I will report this matter right away, and I should be able to give feedback in the afternoon."

Gao Hongming took the card, glanced at it, and carefully put it in his pocket.

For him, both the controlled nuclear fusion project and the requirements of Academician Xu are the focus of the focus.

The former is a key national project, and the latter is even more needless to say.

Now that the two are superimposed together, it can be said that as long as there is a requirement, it will inevitably be reported and processed in the most direct and fastest way.

If it is other projects, not only do you need to fill in a lot of information forms to apply for a national supercomputing center, but you also have to review the application processing model or the data that needs to be calculated. It will take two or three months to go through all the queuing processes.

Hearing this, Xu Chuan nodded and smiled: "In this case, I'll wait here."

He can still wait for half a day.

At the foot of Qixia Mountain, after a stroll in the controlled nuclear fusion industrial park, Xu Chuan once again saw what "China speed" means.

In just a few months, buildings have been built here according to the planning map.

Although the core area is still processing the underground area, the buildings in the surrounding living park and research park have been built.

It is estimated that in two or three months, the research team responsible for the controlled nuclear fusion project will be able to move from the Xianlin campus as a whole.

Of course, there are still many equipment needed for the experiment that are being purchased and manufactured.

After all, controlled nuclear fusion is a super project, involving equipment such as the reactor's plasma orbit, external field coils, water-cooled divertors, power generation heat engines, etc., which cannot be handled by one or two or even one or two hundred companies.

This kind of super project requires the strength of a country, and it must be supported by a major country to proceed smoothly.

Xu Chuan has never worried about the construction of the park. For a construction maniac, the construction of the park will be completed before the time it is agreed to be completed.

But when it comes to reactor parts, it is not certain.

Those extremely high-precision parts, not to mention domestic, even the world, there are not many manufacturers that can produce them.

So after the verification of the mathematical model is completed, he still has to find a reactor in China to test it to see if it can really complete the control of ultra-high temperature and high-pressure plasma turbulence as in the verification.

At around three o'clock in the afternoon, Xu Chuan, who was communicating with Qi Zhongxing about construction issues in the park, received good news from Gao Hongming.

"Academician Xu, regarding the application for the supercomputing center you need, we have communicated with various supercomputing centers. At present, there are two supercomputing centers that can spare some computing power within a week to complete the task."

"The first is the Yangcheng Center, which is equipped with the "Tianhe-2" supercomputer and related systems."

"The second is the Gucheng Center, which is equipped with the "Tianhe-1" supercomputer and the "Tianhe-3" prototype system."

"I have printed out the information related to these two supercomputing centers. Would you like to take a look first?"

As he spoke, Gao Hongming handed the folder in his hand to Xu Chuan.

After taking the folder, Xu Chuan took out two documents from it.

The first document is the supercomputing center in Yangcheng. This supercomputing center is located in SYS University in Yangcheng University City and has the "Tianhe-2" supercomputer independently developed by Huazhong University of Science and Technology.

The peak computing speed is 5.49×10 to the 16th power per second, and the continuous computing speed of double-precision floating-point operations exceeds 3.39×10 to the 15th power per second. It is mainly used for computing in high-tech industries and modern service industries, digital city construction and scientific research fields.

The second document is the supercomputing center of Gucheng Center. This supercomputing center is located in the BHX area of ​​the ancient city. Compared with the supercomputing center in Yangcheng, its computing performance is a little weaker.

But it has a unique advantage, that is, it is mainly used in aerospace, meteorological research, controlled nuclear fusion, civil engineering design and analysis, high-end equipment manufacturing and other fields.

For calculation and research in fluid mechanics, it has advantages that other supercomputing centers do not have.

Xu Chuan flipped through the information and decided where to do the experiment.

After handing the file in his hand back to Gao Hongming, he said: "Please apply for the supercomputing center in Gucheng. The sooner the better. Just call me after the application is approved. I will go there with the model."

For computing power, a national supercomputing center is enough for him to toss.

Even the relatively backward Gucheng supercomputing center is only relatively backward compared to other national supercomputing centers.

It is enough to allocate some computing cores at random.

Its year-round calculation and research on fluid mechanics is an advantage that other supercomputing centers do not have.

Taking advantage of this, maybe he can optimize the phenomenological model in Gucheng.

Although it is not necessarily very large, don’t underestimate this optimization. For a mathematical model with countless calculation variables, even an optimization of only one ten thousandth can save a lot of computing resources in the final calculation.

Gao Hongming nodded and said, "Okay, I will accompany Academician Xu there then."

After dealing with matters related to the mathematical model, Xu Chuan did not stay in the nuclear fusion industrial park. He went straight to the Sichuan-Hai Materials Research Institute.

In October, he assigned the institute the task of studying superconducting materials and carbon-based materials.

They are not required to produce any results, but are required to continue conducting experiments, which is equivalent to throwing money at experimental data.

There is no way. Compared with old research institutes or laboratories with decades of experience in materials research, the Sichuan-Hai Materials Research Institute has too little experience.

If it were another laboratory that has been studying superconducting materials for more than ten years, it can be said that there is no need to spend so much money and experimental data.

The experimental data accumulated over time is enough for him to use.

But every piece of experimental data is the most important information for a research institute or laboratory and is the foundation of the laboratory. It is impossible to sell it to others without special circumstances.

So Xu Chuan could only spend money and time in exchange for experimental data.

Summarizing experience through constant trial and error and finding a path to the key points are the only way for all materials science experiments.

The computational simulation model he developed is indeed a promising method, but it must ultimately be implemented in specific experiments.

No matter how awesome mathematics is, unless you are an omniscient and omnipotent god, it is impossible to completely replace all experiments.

I can only help you introduce some time or unnecessary detours.

Knocking on the door of the office, Brother Fan Pengyue, who was in charge of managing the Chuanhai Materials Research Institute, was handling work. When he saw Xu Chuan coming, he stood up with a smile to greet him.

"Academician Xu's great presence has brought glory to the humble house."

Xu Chuan rolled his eyes at him and said, "I am talking like a guest."

Fan Pengyue laughed and said: "You haven't even been here a few times this year, and the shopkeeper has done it too simply. I'm really not afraid that I will join others to swallow up your laboratory. At least hundreds of millions of funds have been invested so far. "

Xu Chuan glanced at him and said, "You can try. Even if you succeed, it will only be 100 million, which is not much to me."

Fan Pengyue said with a smile: "Forget it, when the time comes my mentor will expel me from the school and it will be over."

"And in China, where can I go after someone steals your stuff? There are giants at the level of academicians of the two academies. I'm afraid I can't even get out of this office door without someone pointing at my head."

Xu Chuan shook his head and said: "Don't be impatient. I'm coming over this time to see how the previously arranged experimental research is going. If the data is sufficient, I will start conducting experiments on copper-carbon-silver composite superconducting materials. Research."

When it came to business, Fan Pengyue stopped playing around. He thought for a while and then said: "Two months are still a bit tight. There are currently eleven sets of experiments in the experimental research on copper-carbon-silver composite materials, and we have accumulated a lot of experience." There are about five hundred sets of experimental data.”

"As for graphene and carbon nanotubes, because the equipment was only shipped in the middle of last month, less than fifty sets of controlled experiments have been done so far."

Xu Chuan nodded and said: "This efficiency is not bad. I guess you must have worked a lot of overtime."

Each set of exploratory experiments on copper-carbon-silver composite materials takes quite a long time, ranging from a few hours to a day or two.

"Yes." Fan Pengyue nodded and continued: "In the past two months, I have indeed worked a lot of overtime."

Xu Chuan: "It's okay to work overtime, as long as the off-duty and overtime wages are paid according to the standard."

Fan Pengyue nodded and said, "Don't worry, you won't miss any buttons."

"I won't look at the overall data. Is there any compiled data?" Xu Chuan then asked. Five hundred sets of experimental data can generate a large amount of data.

Most of these data will be repeated or discarded, and only a small part of the data may bring some hope of leading to the correct synthesis path.

It is also troublesome to select useful data from these data, including how to analyze and process these data and bring them into the material calculation model. It is also troublesome and cumbersome. Fortunately, he now has enough people under his command to do this. Work.

Fan Pengyue nodded and said: "Of course, every experimental data is saved, and then possible suitable methods and paths will be selected through analysis. As for the basic data, those have been entered into the material calculation model."

"Currently, the most optimized route is to use nano-synthesis technology to composite copper-carbon-silver materials through inert gas protection and then undergo sintering and other treatments. After a series of screening and purification, chemical deposition is used on the base layer. Deposited in the form of a two-dimensional film to form a crystal structure."

"This two-dimensional film sheet is superimposed and then frozen at ultra-low temperature by liquid helium, which can realize the characteristics of copper oxide low-temperature superconducting materials."

"This is currently the first to achieve ultra-low-temperature superconductivity in a copper-carbon-silver composite material."

"As for other experiments, they have not yet demonstrated this potential."

Hearing this, Xu Chuan was a little surprised and said, "There is a breakthrough so soon?"

Fan Pengyue nodded and said, "Well, it has been tested. At a temperature of 43.5K, this copper-carbon-silver composite two-dimensional thin film material has the characteristics of a superconducting material."

Xu Chuan's eyes showed a hint of interest, and he said, "Go and have a look at this first, and give me the detailed information of this route and the information of the person in charge."

To be honest, he was still a little surprised that the Chuanhai Materials Research Institute could find a route to ultra-low temperature superconductivity of copper-carbon-silver composite materials so quickly.

Moreover, this route is very close to the route he took in his later research on copper-carbon-silver superconducting materials, which surprised him even more.

Even if he gave a research direction at the beginning, it was just a vague path.

Copper-carbon-silver composite materials have countless synthesis methods and countless material ratios.

A slight deviation in the synthesis process may result in two materials with very different performances.

In two months, he was able to explore a relatively correct path on this vague path, which shows that this researcher is quite capable.

Of course, there is a certain possibility that it is just a blind cat catching a dead mouse, and luck is good to take the right route, but luck is actually a part of strength in materials science.

Sometimes luck is good, and you can really go straight to the end of a smooth route and synthesize the required materials directly.

However, the probability of this is very low, and it will be almost the same when Senior Bai comes.
