Chapter 468 Technology Prepared for the Development of Mars

In the computer room of the material calculation model group, Xu Chuan opened the code of the graphene module and read it carefully.

He naturally understood the mathematical model, but not much.

After all, he was not a student of this major and had not studied it systematically.

Of course, after others had written the code and put it in front of him, it was no problem to understand the meaning of it.

"Here, a quantum mechanics calculation program of the plane wave-pseudopotential density functional method was added, and an atomic orbital linear combination method was used."

"Here, a hybrid method of quantum mechanics and molecular mechanics was introduced, combining the advantages of high precision of quantum mechanics and high efficiency of force field calculation."

"."

"From the program point of view, this method can reduce the calculation cost while performing high-precision calculations on large systems, and can simulate calculations on organic and inorganic molecular systems."

It took some time for Xu Chuan to check the relevant code of the graphene module.

What puzzled him was that if only these things were changed, the computing power of the graphene module should not be greatly improved.

After all, these directions 1 are quite conventional. Although there is indeed an improvement, it should not be so great.

According to Fan Pengyue, the changes were not only in this part, but also in other modules.

After clicking on this part, Xu Chuan flipped through it, and his eyes suddenly focused.

[//Algorithm Set]

In the algorithm field of the graphene module, he saw something new. After quickly flipping through it, he immediately understood why the computing power of the graphene module has been greatly improved.

He also knew the key to why the reduction of graphene oxide is carried out directly through electrochemical reduction without using a reducing agent.

After reading this algorithm set, Xu Chuan breathed a sigh of relief.

With his eyes, he could naturally see the underlying logic of this algorithm.

In this algorithm set, the senior sister Liu Jiaxin made an independent algorithm set for lithium iron phosphate batteries and rigid, non-ionic or ionic molecules mainly composed of C, O, H, Li, Fe, and P.

By referring to the underlying physical properties and bonding methods, the various possible stacking and arrangement forms of generating a given molecule in the space group are searched for the crystal structure with the lowest energy.

Then on this basis, another Biovia algorithm was introduced to predict the relationship between atomic and molecular structures and properties and performance in another computational material.

This method is used to deduce the electrochemical process of graphene manufacturing for lithium iron phosphate batteries.

It is a very clever method, but it has to be said to be very useful.

At least it can combine more possibilities through limited conditions.

Of course, this algorithm set also has disadvantages. It has great limitations. Although it is useful, it is only applicable to lithium iron phosphate and graphene.

It is inferred by rigid, non-ionic or ionic molecules composed of C, O, H, Li, Fe, and P, and is based on the mathematical method he originally did.

In layman's terms, this algorithm set is somewhat similar to a banyan tree. After its roots spread out, they break through the ground and grow into another tree in the distance.

It seems independent, but its roots still come from the main root system.

"It's a very clever way, but there should be someone in the field of computational materials who can figure out the principle here, right?"

After reading the optimized graphene module program, Xu Chuan looked up at Fan Pengyue and asked.

Master Xiong nodded, scratched his head and replied a little embarrassedly: "I know, of course I know, but that algorithm set involves the mathematical formulas of your junior sister's structure, which is very difficult."

"You know, although the computational materials department has been recruiting people, it is too difficult to dig out a top-level person who is proficient in mathematics and algorithms."

"Talents of this level are generally in major foreign top laboratories. It is basically impossible to dig them out."

After hearing Fan Pengyue say this, Xu Chuan suddenly remembered that he had ignored the mathematical methods in the algorithm set.

From his point of view, the optimized mathematical methods in graphene are indeed very simple, after all, his mathematical ability is top-notch.

But in the eyes of other scientific researchers in the field of computational materials, the difficulty is quite great.

And top talents like senior sister Liu Jiaxin, who have been offered by famous companies such as Google and Apple, and the highest annual salary is even 1.6 million yuan, are basically tied to major companies.

Even if they are placed in companies such as Google and Apple, they are all chief engineers and have the ability to influence an entire industry.

Such talents, in addition to annual salary, basically have stocks, options and other rewards sold by other parties. How could they be easily poached?

After thinking it through, he smiled and shook his head, saying: "Okay, I will go to find Senior Sister Jiaxin when I have time, and then talk about the optimization of the computational model."

After a slight pause, he continued: "However, computational materials science is very large, and it is impossible to rely on a single method to cover all types of materials."

"And as more and more mechanisms and algorithms of various materials are added, it is inevitable that the model will become larger and larger."

"As for the computing power problem, build a large supercomputing center by yourself."

Hearing this, Fan Pengyue thought for a while and said: "It is indeed feasible to build a supercomputing by yourself, but will the cost be too high?"

"If we want to be able to perfectly run the institute's calculation model, we will probably need more than 2 billion in funds, and it's still rice gold."

Although with the realization of controllable nuclear fusion technology, Mijin has continued to fall, while RMB has been rising.

However, under the deliberate control of China, the current exchange rate between Mijinqi and RMB remains at around 1:5.

Two billion meters of gold, converted into more than 10 billion RMB.

Xu Chuan shook his head and said: "Just like the 'Anton Supercomputer', a supercomputer in the chemical industry, if we just build a supercomputer for targeted material calculation models, the funds required are not too much, and the research institute can afford it. "

After a pause, he continued: "And the purpose of my previous establishment of the Sichuan-Hai Materials Research Institute was actually not to make much money from it."

"Although making money is one aspect, the purpose of its establishment is to explore more science. In this regard, problems that can be solved with money are not a problem."

"And in addition to Chuanhai Materials Research Institute, Chuanhai Network Technology Company also has a demand for supercomputers. It is still possible to build a supercomputer and use it together for two companies."

Fan Pengyue nodded and said: "Since you have decided, I will find someone to study it later. I will send you a plan when I have it."

"OK."

Xu Chuan nodded in agreement, chatted with the senior brother in the office for a while, and made a plan for the next arrangements of the Sichuan-Hai Materials Research Institute.

Although he usually comes here less often, the overall direction still needs to be controlled.

After chatting for a while, Xu Chuan left for another company under his name, Chuanhai Network Technology Co., Ltd.

The batch synthesis results of graphene will not be available until after three o'clock in the afternoon. There is still time, so why not go to the senior sister's place to have a look.

‘Chuanhai Network Technology Co., Ltd.’ was newly established by Liu Jiaxin after returning from Princeton.

Of course, it is said to be newly established, but it is actually more than a year ago.

Its main purpose is to build a network security protection platform for Chuanhai Materials Research Institute, and on the other hand, it is to develop the fields of artificial intelligence and big data.

More than a year is not enough for this company to grow much.

After all, he is not a professional in the computer field and cannot drive the development of the laboratory through his own research like the Chuanhai Institute of Materials.

However, with sufficient financial support, its development is still quite smooth.

At least it has rented a two-story office building in the industrial zone near Zijin Mountain, and has hundreds of programmers and corresponding company personnel.

After arriving at Chuanhai Network Technology Co., Ltd. smoothly, Xu Chuan found Liu Jiaxin who was busy working in the office.

With a smile, he knocked on the door. The senior sister who was awakened looked up and was obviously stunned when she saw him, and then a smile appeared on her face.

"How did you come."

Xu Chuan smiled and joked: "Although I haven't been here for a long time, you can't forget that this is my company."

Hearing this, Liu Jiaxin's face turned slightly red and she said with some embarrassment: "That's not what I meant."

Xu Chuan smiled and said: "I just came from Sichuan-Hai Materials Research Institute. I heard that you helped optimize the model there?"

Liu Jiaxin thought for a while, nodded and asked nervously: "Well, I did help improve the model in June. Is there something wrong?"

Xu Chuan pretended to be serious and said: "Problem? There is a big problem!"

Hearing this, Liu Jiaxin suddenly became nervous: "What, what's wrong?"

Seeing this, Xu Chuan stopped teasing her and said with a smile: "The problem is that the model you optimized is too good and it has played a big role. Senior Brother Fan wants me to arrest you and continue to work as a coolie."

Seeing that there was nothing wrong with what she helped to revise, Liu Jiaxin relaxed, secretly breathed a sigh of relief and said, "Then I will help revise it when I have time?"

Xu Chuan shook his head and said with a smile: "It's not urgent. I came here mainly to ask you for a favor."

As he spoke, he handed over the document he had brought from the Chuanhai Materials Research Institute, and continued: "I have seen your modified model at the research institute, as well as some of their experimental data on graphene. Got some new ideas.”

"Concerning carbon dioxide, I want to design a synthesis route."

Xu Chuan succinctly stated the concept that came to mind at the Chuanhai Materials Research Institute in the morning, and then said:

"There are many carbon compounds, ranging from organic proteins and fats to inorganic petroleum, hydrocarbons, graphene and other materials, which can be synthesized. But correspondingly, this process requires a computational model to improve the relevant synthesis routes, and Manufacturing carbon dioxide collection devices and synthesis devices, among other things.”

"The mathematical method you use when optimizing the calculation model is very suitable for the related algorithm set. An independent algorithm set has been made for non-ionic or ionic molecules. Although the reference field cannot be extensive, it uses carbon as the core and then derives The scope of other materials is relatively small and more suitable for your logic. "

After looking through the document in her hand and listening to Xu Chuan's request, Liu Jiaxin thought for a while and said: "If you can provide the formula of the carbon synthesis route and related information, I can give it a try, and it should be possible. "

"Compared to the graphene module of the previous optimization institute, carbon synthesis of carbon compounds is generally done by adding hydrogen to increase the long chain. The difficulty lies in the fact that carbon dioxide is a very stable molecule. Its catalytic reaction with hydrogen molecules produces more short-chain hydrocarbons such as methane, ethane, and propane. It is difficult to obtain long-chain hydrocarbons in gasoline fuel."

Hearing this, Xu Chuan looked at Liu Jiaxin in surprise: "Do you understand materials?"

Liu Jiaxin pursed her lips and said: "There is research in this area at Princeton. I learned a little when I was there. I participated in a project and built a related mathematical model."

Xu Chuan smiled and said: "That's great. I will send you some information when I go back. You can take a look at it first. When I finish my work, we will study this together."

After thinking for a while, he added: "There is no need to rush this. It is a technology to prepare for the future. You can take a look at it when you have time. You don't need to work overtime."

He knew the personality of this senior sister. If he didn't say it, he would definitely raise the priority of this matter to the highest level and work overtime to deal with it.

But regarding the technology of collecting and converting carbon dioxide into synthetic carbon compounds, he is preparing for the future landing on Mars or even the development of Mars.

The atmosphere on Mars is very thin, but more than 96% of the atmosphere on Mars is carbon dioxide.

And through historical space landing research data, it is shown that there is a large amount of carbon dioxide in the surface soil of Mars.

For example, at the poles of Mars, there are a large amount of water ice composed of a mixture of carbon dioxide and water.

On Mars, whether it is the Arctic ice cap or the Antarctic ice cap, it can even reach thousands of kilometers during the aphelion period, which shows that the water ice and carbon dioxide contained are extremely rich.

Compared with transporting these materials from the earth, the cost of synthesizing various carbon compounds using carbon dioxide, water, and oxygen and hydrogen after water electrolysis will undoubtedly be reduced by hundreds, thousands or even tens of thousands of times.

This provides real feasibility for the development of Mars.

Even if the grand plan of comprehensively transforming Mars is finally denied, this technology can still provide great convenience for establishing colonies and permanent bases on Mars.

Of course, the technology of converting carbon dioxide into synthetic carbon compounds is not useless on Earth.

Although the carbon dioxide content in the atmosphere on Earth is low, the atmospheric concentration is not comparable to that of Mars.

More importantly, carbon dioxide is a by-product of many products. Under the low-carbon policy, using this technology to synthesize it into other valuable products is also promising.

Its future is worth looking forward to.
