Chapter 338 Breakthrough of Superconducting Materials
With the optimized mathematical model, Xu Chuan found Gao Hongming, who was assigned by the Science and Technology Center to be responsible for the overall work, and explained his intention.
"No problem, I'll report to the superiors right away."
"But do you have any requirements in terms of performance for the supercomputing center you are applying for?"
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 piece of cardboard from the backpack behind him, handed it over, and said: "The performance requirements are all above. In terms of time, the sooner the better. I'll trouble you, Gao Ding, about this."
"No, no, no, Academician Xu, please don't say that. It is my duty to cooperate with your work and protect your needs. I will report this matter right away. I should be able to give feedback in the afternoon."
Gao Hongming took the card, glanced at it, and carefully put it into his pocket.
For him, both the controllable nuclear fusion project and Academician Xu's requirements are the key points.
The former is a key national project, and the latter is needless to say.
Now that the two are superimposed together, it can be said that as long as there is a request, the report will be processed in the most direct and fastest way.
For other projects, applying for a national supercomputing center requires not only filling out a lot of information forms, but also reviewing the model to be applied for or the data to be calculated. The various queuing processes take no more than two or three months. The time is simply not available.
Hearing this, Xu Chuan nodded and said with a smile: "In that case, I'll wait here."
He could still afford to wait for half a day.
At the foot of Qixia Mountain, walking around the controllable nuclear fusion industrial park, Xu Chuan once again witnessed what is called "China's speed".
In just a few months, buildings were built here one after another according to the plan.
Although the core area is still dealing with the underground area, the buildings in the surrounding living park and research park have been built.
It is estimated that in another two to three months, the research team responsible for the controllable nuclear fusion project will be able to move from the Xianlin campus as a whole.
Of course, a lot of the equipment needed for experiments is still being purchased and manufactured.
After all, controllable nuclear fusion is a super project that involves equipment, such as the reactor's plasma orbit, external field coils, water-cooled divertor, and power generation heat engine. It cannot be done by one or two companies or even one or two hundred companies. .
This kind of super project requires the power of a country, and it must be fully supported by a major country in order to proceed smoothly.
Xu Chuan has never worried about the construction problems of the park. For an infrastructure fanatic, if the construction of the park is scheduled to be completed when it is scheduled to be completed, it will be completed before that point.
But when it comes to reactor parts, that's not necessarily the case.
Not many manufacturers in the world, let alone in China, can produce those extremely high-precision parts.
Therefore, after completing the verification of the mathematical model, he had to find a reactor in China to test it to see if it could really successfully control ultra-high temperature and high pressure plasma turbulence as in the verification.
At around three o'clock in the afternoon, Xu Chuan, who was discussing construction issues with Qi Zhongxing in the park, received good news from Gao Hongming.
"Academician Xu, regarding the application for the supercomputing center you need, we have communicated with the major supercomputing centers. Currently, there are two supercomputing centers that can free up part of the computing power to complete the task within a week."< br>
"The first one is Yangcheng Center, which is equipped with the "Tianhe-2" supercomputer and related systems."
"The second one is Gucheng Center, which deploys 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?"
While talking, Gao Hongming handed the folder in his hand to Xu Chuan.
After taking the folder, Xu Chuan took out two pieces of information.
The first information is the Yangcheng Supercomputing Center. This supercomputing center is located at SYS University in the University Town of Yangcheng. It has the "Tianhe-2" supercomputer independently developed by Huake University.
The peak calculation speed is 5.49×10 to the 16th power per second, and the continuous calculation speed of double-precision floating point operation exceeds 3.39×10 to the 15th power per second. It is mainly used for calculations in high-tech industries and modern service industries, digital city construction and scientific research fields. .
The second information is about the supercomputing center in the center of Gucheng. This supercomputing center is located in the BHX District of the ancient city. Compared with the supercomputing center in Yangcheng, its computing performance is weaker.
But it has a unique advantage, that is, it is mainly used in aerospace, meteorological research, controllable nuclear fusion, civil construction design 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 looked through the information and decided where to do the experiment.
After handing the document in his hand back to Gao Hongming, he said: "Please Gao Ding, please apply for the supercomputing center in Gucheng. As for time, the sooner the better. Just call me after you apply. I will bring you Walking past the model ”
As for computing power, a national supercomputing center is enough for him.
Even the Gucheng Supercomputing Center, whose performance is relatively lagging, is only lagging behind other national-level supercomputing centers.
It is enough to randomly divide some computing cores.
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 to conduct 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 Sichuan-Hai 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 speaking 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 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 smiled and said: "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 if I steal your things? 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." 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 time off 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 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: "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."
There was a trace of interest in Xu Chuan's eyes and he said: "Go and take a look at this first, and also give me the details of this route and the information of the person in charge."
To be honest, he was a little surprised that the Sichuan-Hai Materials Research Institute could find a route to ultra-low-temperature superconductivity in copper-carbon-silver composite materials so quickly.
Moreover, this route was very close to his later research route on copper-carbon-silver superconducting materials, which surprised him even more.
Even if he gave a research direction at the beginning, it was only a vague path.
There are countless synthesis methods and material ratios for copper-carbon-silver composite materials.
If there is a slight deviation in the synthesis process, two materials with greatly different properties may appear.
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 a blind cat meets a dead mouse and gets lucky and takes the right route, but luck is actually a part of strength in materials science.
Sometimes if you are lucky, you can go through a very smooth route to the end and directly synthesize the required materials.
But this probability is very low. It will be almost the same when Senior Bai comes.
