Chapter 842 Porous Liquid DAC Carbon Dioxide Capture System

Nanjing University, on campus, Xu Chuan sat in his office to handle the work at hand.

Since the magnetic polariton electromagnetic shield generator technology has achieved phased results, he has basically been traveling back and forth between Xinghai Research Institute and Nanjing University campus.

The main work of the institute is still in the field of aerospace.

Whether it is plasma electromagnetic deflection shield, the construction of lunar research base, or the research and development of neutrino communication technology, from the perspective of the institute, these are all prepared for aerospace.

As for Nanjing University, on the one hand, it is to guide the study of several students, and on the other hand, it is to teach students of Nanjing University.

"Professor, my graduation thesis has been officially published."

In the office, after two hurried knocks on the door, Tong Yang walked in with a flushed face and light footsteps with excitement and excitement in his voice.

Xu Chuan, who was reviewing the documents, was slightly stunned for a moment, then reacted and said with a smile: "Congratulations."

Tong Yang, one of the two doctoral students among the four students enrolled in 2021. After studying with him for more than three years, it is now the time for graduation.

Xu Chuan took the journal from the student with a smile and flipped through it.

The second paper in the latest issue of "New Advances in Mathematics" is Tong Yang's paper "Study on the Optimal Pinch Problem Based on the Minimum Legendrin Submanifold on the Unit Sphere".

From the submission of the manuscript in early July to the middle and late October now, it has been almost three months.

The manuscript was approved at such a fast speed, although it is inseparable from his name being listed as the corresponding author, which greatly improved the review efficiency of "New Advances in Mathematics".

But the fact that the manuscript was approved within three months and officially published is enough to prove the excellence of this paper.

At least it can be said that it was approved in one go and was not sent back for revision.

Flipping through the journal in his hand, Xu Chuan smiled and said: "A paper in the Big Four does not disappoint your efforts over the years. It is a very good paper. I hope that after graduation you can always maintain your desire for knowledge on the road of mathematics, keep moving forward, and create more achievements."

In the office, Tong Yang was relieved to hear his mentor's blessing, and smiled and said: "I will definitely remember your teachings."

Xu Chuan smiled, put the journal in his hand on the table, and asked: "Are you ready for the graduation defense? When will it start?"

Tong Yang had some hope in his eyes, and quickly said: "The graduation defense is scheduled for the afternoon of two days later. Professor, do you have time to attend then?"

Although he did not reach the height of the previous three seniors in academic research, he still hoped that his mentor could be present at such an important moment in his life as the doctoral graduation defense.

However, he was not very sure about this point. After all, he knew how busy his mentor was.

Xu Chuan smiled and nodded, saying: "Of course."

As a mentor, he still had to take some time to attend such an important moment in the student's graduation defense.

Hearing this, Tong Yang was relieved.

In addition to this important moment in life, there was another reason that there were too many bigwigs participating in his graduation defense.

There were six full-quota defense committees, five of which were academicians, and one was Rong Zhizhuan, the dean of the School of Mathematics of Nanjing University.

With this scale, without Xu Chuan, Tong Yang really didn't know if he could hold on.

Although he also knew that these academicians and bigwigs came for their own mentors.

After chatting about things related to the graduation defense, Xu Chuan smiled and asked: "Where are you going after graduation? Do you have any ideas?"

Tong Yang thought about it, shook his head, and said: "It has not been determined yet. Several universities and research institutions have sent me invitations, and I don't know what to choose yet."

The job directions of mathematics graduates are not very wide, and it is still difficult to find a job.

Generally speaking, the main jobs of mathematics doctoral students after graduation include university teachers, research institute researchers, quantitative analysts in the financial field, data scientists, etc.

Of course, for him, work matters have never been something that needs to be considered.

With the title of Xu Chuan's student, no matter what industry he chooses, even if he knows nothing, there will be universities or research institutions vying for him. They will even offer him a salary far exceeding his own value.

But for Tong Yang, future development is also something that needs to be carefully considered.

This is not only about his own future, but also about Xu Chuan's reputation.

At least, he is not a person who does not know how to be grateful. Being able to worship Xu Chuan and study for several years is a great gift to him.

The original life trajectory has also been completely changed.

After graduation, he will use Xu Chuan's reputation to go out and "cheat" to obtain things that do not originally belong to him. To be honest, he can't do this.

Xu Chuan smiled and said, "Then you have to make a decision as soon as possible. There are only two days left for the graduation defense."

"As for if you want to work in the research industry, compared to the financial or software industries, I still recommend you to work in mathematical research."

"You can solve the optimal pinching problem of the smallest legendrin submanifold. You are still very talented in mathematics. There is hope that you can go further."

After a pause, he added: "Of course, when it comes to work, the most important thing is your own ideas."

"Whether you choose to stay in school as a teacher or go to a research institute to do research, I respect your choice and can also write you a letter of recommendation."

Tong Yang nodded and said seriously: "Thank you, professor, I will seriously consider it."

Xu Chuan smiled and said: "Go, prepare for your graduation defense."

"Okay!"

Looking at Tong Yang's departing back, Xu Chuan leaned back on the chair, smiled, and felt a little emotional.

The scene of him recruiting these students four years ago is still vivid in his mind. Unexpectedly, in the blink of an eye, it's time to graduate again.

While he was reminiscing about the past, the mobile phone on the table vibrated and a call came in.

Pick up the phone casually, Xu Chuan glanced at the caller ID and was a little surprised.

The call was from Brother Fan Pengyue from the Sichuan Ocean Materials Research Institute.

"Hello, Senior Brother Fan?"

He answered the phone with a smile. As soon as he said hello, a familiar voice came from the other end of the phone.

"Junior Brother Chuan, do you have time now?"

"What's wrong?" Xu Chuan asked with a smile.

"If you have time, come to my side now. One of the technologies you asked us to study has made a major breakthrough!" Fan Pengyue's voice sounded with a smile and a hint of controlled excitement on the other side of the phone.

Hearing this, Xu Chuan's eyes lit up and he quickly asked, "Which one?"

Although the scale of Chuanhai Materials Research Institute is not as large as Xinghai Research Institute, it is no longer the small experiment worth 20 million when he bought it.

Although he has been semi-relaxing this institute for most of the time, after so many years of development, plus the billions of dollars he has invested, the scale of Chuanhai Materials Research Institute is now among the best in the field of materials, even in the world.

As for the technologies being studied, there are even more.

Superconducting materials, lithium batteries, hydrogen fuel cells, graphene, carbon materials, energy storage materials, polymer composite materials, etc. are almost all popular research fields, and the current Sichuan Hai Materials Research Institute has them all.

Of course, the most important research fields are still the ones he personally set.

Superconductivity, batteries, graphene or carbon materials and other fields.

On the other side of the phone, Fan Pengyue said mysteriously: "Keep it secret! You will know when you come, I can definitely give you a surprise!"

Xu Chuan, who was curious about which technology had a new breakthrough, almost pulled his breath up when he heard this, and laughed and scolded unhappily: "Fuck you! Are you the boss or am I the boss?! Keep it secret!"

Fan Pengyue laughed and said: "It's a surprise, and it's the technology you once ordered personally!"

Xu Chuan: "Okay, I'll go over now. If there is no surprise, I'll beat you to death!"

"No need for you to beat, I'll jump down from the building myself!"

After hanging up the phone, Xu Chuan felt a little itchy and quickly called Zheng Hai.

"Hello, Zheng Hai, drive over now."

"Okay, professor, I'll be there right away."

After the short call ended, Xu Chuan stuffed the report documents on the table into the drawer without sorting them out, and went downstairs directly.

It must be said that the sudden call from Senior Brother Fan Pengyue did arouse his curiosity.

One of the technologies studied by the Chuanhai Materials Research Institute has a major breakthrough, and he personally instructed it.

As for the research fields and technologies he selected, no matter which one has a breakthrough, the benefits and development that can be brought are huge.

For example, lithium-air batteries, superconducting materials, or the mathematical model of computational materials science, etc.

A breakthrough in each of these materials or technologies may bring him at least tens of billions of dollars or even more.

With a hint of wanting to beat this riddle man, Xu Chuan got into the car driven by Zheng Hai.

"Where are you going? Professor." Xu Chuan got in the car, and Zheng Hai turned his head and asked.

"Chuanhai Materials Research Institute, hurry up."

"Okay."

Zheng Hai responded and started the car and rushed towards the Qixia Mountain New Development Zone.

With curiosity, Xu Chuan quickly scanned his face to pass the access control and took the elevator to Fan Pengyue's office.

"Tell me, which research has made a major breakthrough, and it is still so mysterious?"

Fan Pengyue smiled, but did not answer the question immediately, but said: "Follow me."

With strong curiosity, Xu Chuan followed the footsteps of this senior brother Fan.

Crossing the corridor and taking the elevator, the two came to a large laboratory on the upper floor of the institute.

After verifying the access control, Fan Pengyue pushed open the door of the laboratory and led the way in.

In the wide laboratory, there was a device that looked a bit like a central air conditioner outdoor unit, and several researchers in white coats were busy around this device.

Xu Chuan looked up and down at the device in front of him, which was not so strange and looked a bit ordinary, and was a little curious.

"What is this?"

He originally thought that there was a new breakthrough in lithium-air battery technology. After all, lithium-air batteries are the key targets of the Sichuan Hai Materials Research Institute and are worth "surprises".

But now it seems not to be.

It is impossible to make a lithium-air battery this large, especially an experimental sample.

He visually estimated that the device in front of him was at least five meters long and three meters wide, and more than two meters high.

Such a huge device could not be a lithium-air battery.

Fan Pengyue smiled and said, "Porous liquid DAC carbon dioxide capture system!"

Hearing this name, Xu Chuan was stunned for a moment, glanced at this senior brother Fan, and then his eyes fell back on the device in front of him, and asked in surprise:

"Carbon dioxide utilization technology, have you made a breakthrough?"

He finally remembered that among the technologies developed by the Chuanhai Materials Research Institute, there was another technology that he had personally instructed a few years ago.

That is, carbon dioxide collects and synthesizes various carbon compounds, such as gasoline, starch, glucose, silicon carbide, hydrocarbons, graphene, and the most important oxygen, etc.

This technology was instructed to the Chuanhai Materials Research Institute very early, almost when he had just completed the controlled nuclear fusion technology, and it has been four or five years now.

This is a technology he prepared for the development of Mars.

The atmosphere on Mars is very thin, but more than 96% of it is carbon dioxide, and historical space research data shows 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.

And even on Earth, this technology has great value.

Although the realization of controlled nuclear fusion technology has delayed the development of the greenhouse effect, the carbon dioxide in the atmosphere cannot be digested and absorbed by vegetation in a short time.

And it is not a comprehensive shift of energy from fossil fuels to the field of electricity, which cannot be done in a short time.

Therefore, just collecting carbon dioxide from the air, reducing the greenhouse effect, and protecting the earth's environment has great application value.

Not to mention that as electricity becomes cheaper, converting these carbon dioxide into gasoline, starch, glucose, silicon carbide, hydrocarbons, and graphene is no longer an unattainable technology.

The only key point is how to capture the "thin" carbon dioxide from the air.

Yes, it is thin.

Although the greenhouse effect is becoming more and more serious, the total proportion of carbon dioxide in the atmosphere is actually only about 0.04%.

Of course, the proportion of carbon dioxide in cities and rural areas is definitely different, but how to recycle the extremely low proportion of carbon dioxide in the total mass is a huge problem.

Whether it is the traditional adsorption method using amines and other substances, or the pressure swing adsorption method, or the organic membrane separation method, they are basically only suitable for environments with high carbon dioxide concentrations.

For ultra-low concentrations of carbon dioxide in the atmosphere, they are useless.
