The Science Fiction World of Xueba

Seeing Sophon driving Alice away, Pang Xuelin returned to the room and found that Qi Xin had fallen asleep. He smiled, lifted the quilt and got into bed.

Sleep till dawn.

In the world of Resident Evil, although Pang Xuelin spent most of the time in the Kempten base, and the Kempten base was not besieged by zombies.

But in that environment, no matter where Pang Xuelin was, he would sleep with a tight string.

Now that he finally returned to a safe environment, he finally relaxed and slept very comfortably this time.

Early the next morning, Pang Xuelin received a call from Tomoko, saying that she was going to send Alice to the United States and find a way to get Alice back after obtaining legal status there.

In this regard, Pang Xuelin naturally cannot deny it.

Even if this kind of thing is done by oneself, Sophon may not be able to do it well, it is better to let Sophon take full power to handle it.

After breakfast, Pang Xuelin sent Qi Xin to school first, and then returned to the office.

In the office, Pang Xuelin called up relevant papers on organ cloning technology from the system, and browsed them roughly.

There are more than 20 papers related to this technology, including directional induction of stem cells, in vitro differentiation of organ tissues, in vitro organ maintenance technology, etc., each of which is at least equivalent to an S-level paper, and three or four of them even reach the Nobel Prize level.

If Pang Xuelin produces all these papers in one go, it will be equivalent to a super nuclear bomb in the fields of biology and medicine, which will have a very large impact on the entire human medical system and medical ethics.

However, releasing these papers slowly is something Pang Xuelin needs to consider.

No matter whether it is Qiantang Laboratory or Jiang University, Pang Xuelin still does not have a suitable biomedical research platform, and he can't find a suitable excuse to send out the paper.

In addition, Pang Xuelin had to find a suitable platform if he wanted to get involved in biomedical research.

After pondering for a moment, Pang Xuelin said to MOSS: "MOSS, help me investigate the current research and progress of Atom Probe Tomography (APT)."

"Okay, Professor Pang!"

Although Pang Xuelin did not get the dynamic atom probe tomography (APT) technology during this trip to the world of Resident Evil, the promotion of this technology for biology is obvious.

Therefore, Pang Xuelin wanted to see if he could restore this technology in the real world.

After staying in the office all morning, after finding the information he wanted through MOSS, Pang Xuelin got up and went to Qiantang Laboratory.

With the official approval of the aerospace plane and the electromagnetic orbital space launch system project, the construction work of Qiantang Laboratory has been accelerated a lot.

At present, the first phase of the Qiantang Laboratory has been completed, and the first batch of scholars from all over the world who have signed contracts with Qiantang Laboratory have settled in one after another.

The Carbon Nanomaterials Research Center and Jinlong Battery Research Center, which were originally located in Jiangda Yuquan Campus, have also been relocated.

The new generation of flying edge material black box reaction equipment developed by Wanyi and others has also been installed in Qiantang Laboratory, and the output is more than ten times higher than that of the previous equipment in Yuquan Campus.

In the future, they will also cooperate with Xinkai Materials Co., Ltd. to develop a real industrial-grade flying blade material production line with an annual output of more than 100 tons. Only then can the electromagnetic ejection track project enter the formal construction stage.

"Professor Pang, the supercomputing center, carbon nanomaterials engineering laboratory, Jinlong battery research center, and nanomaterials and device research center have all completed construction work, and are expected to officially start operation within one to two months. In the next six months, Key laboratories for 3D micro-nano processing and characterization research, condensed matter physics laboratories, and superconducting materials research centers will also be completed one after another.

Then you can show your skills. "

Academician Xu Xingguo, executive deputy director of Qiantang Laboratory, is accompanying Pang Xuelin to inspect the preparatory work of the entire Qiantang Laboratory.

Xu Xingguo had been the dean of the School of Materials Science and Engineering of Jiangda University before, and the cooperation between the two has been very pleasant.

After Qiantang Laboratory started preparations, he was pulled over by Pang Xuelin to take over as the director of Qiantang Laboratory.

Pang Xuelin nodded, pondered for a moment, and asked: "Professor Xu, later you will find Professor Yang Heping, director of the Nanomaterials and Devices Research Center, and Professor Anderson White, director of the Key Laboratory of 3D Micro-Nano Processing and Characterization Research. A more important project needs to be discussed with them."

Xu Xingguo was taken aback for a moment, nodded and said, "Okay, then let's go to the meeting room in Building No. 2 first, and I'll call them."

Half an hour later, Yang Heping, Anderson White and his assistant and translator all rushed over.

After everyone sat down in the conference room, Yang Heping took the lead and said, "Professor Pang, what's the matter with you suddenly calling us here?"

Yang Heping previously worked at Stanford. He is a tenured professor of the Department of Materials Science and Engineering at Stanford University. He is the associate editor of Nano Express, a top journal in the field of nanomaterials, and the director of the Bay Area Nano Alliance. He has deep knowledge in the field of carbon nanotube CMOS devices. When Jiangda produced carbon nanotubes with electronic grade purity, Yang Heping had the intention to cooperate with Jiangda.

This time Qiantang Lab recruited top scholars from all over the world. Yang Heping returned to China alone. After a long and in-depth conversation with Pang Xuelin, he gave up his teaching position at Stanford and chose to take over the post of director of the Nanomaterials and Devices Research Center of Qiantang Lab.

And Anderson White, this guy is an old friend of Cotton Walker, who previously worked at MIT. Because Anderson White had a disagreement with MIT on the issue of scientific research funding, he took the initiative to find Cotton Walker. , hoping to find a teaching position in China through Kirton Walker.

So Kirton Walker recommended him to Pang Xuelin.

Anderson White's main research field is micro-nano manufacturing.

The so-called micro-nano manufacturing technology refers to the design, processing, assembly, integration and application technology of parts with scales of millimeters, microns and nanometers, as well as components or systems composed of these parts.

Among them, there are two directions: micro-manufacturing and nano-manufacturing.

There are two different micro-manufacturing processes in micro-manufacturing. One is lithography technology, LIGA technology, bonding technology, packaging technology, etc. based on semiconductor manufacturing technology. Expensive equipment and other problems, and can only process two-dimensional or quasi-three-dimensional micro-mechanical parts with simple structure, and cannot process complex three-dimensional micro-mechanical parts; the other is mechanical micro-machining, which refers to the use of mechanical processing, special processing and other The micro-machining technology formed by traditional processing technologies such as forming technology can process three-dimensional complex curved surface parts, and the processing materials are not limited, including micro-grinding, micro-turning, micro-milling, micro-drilling, micro-stamping, micro-forming, etc.

Nanomanufacturing refers to the manufacturing technology of nanoscale structures, devices and systems with specific functions, including nanoimprinting technology, scribing technology, atomic manipulation technology, etc.

The arrival of these two big cows will provide important assistance for Qiantang Laboratory in the fields of nanomaterials and precision machinery.

Pang Xuelin said: "Professor Yang, I called you and Professor Anderson over today. I have a more important job for you."

"What job?"

Yang Heping said.

After the assistant's translation, White also looked at Pang Xuelin curiously.

Pang Xuelin smiled slightly and said: "Professor Yang, Professor White, I hope to develop a dynamic atom probe tomography scanning technology for research in the fields of materials science and biology?"

"Dynamic Atom Probe Tomography?"

Yang Heping and White couldn't help being slightly taken aback.

Yang Heping said: "Professor Pang, I know that atom probe tomography is a technology that provides three-dimensional tomographic images and chemical identification at the atomic scale, mainly for hard materials, and its application fields have expanded from conductive metal materials to semiconductor materials and non-conductive materials. Ceramics and other materials, what about the dynamic atom probe tomography scanning technology you mentioned?"

Pang Xuelin smiled and said: "Dynamic atom probe tomography technology is used to analyze the motion of atoms in biomacromolecules from femtoseconds to microseconds, so as to construct the atomic structures of biomacromolecules such as proteins and RNA. A more accurate description of the biodynamic function of these molecules provides still. In addition, this technique can also be used to analyze the thermal vibration of atoms in hard materials and the behavior of molecules in fluids, so as to establish a more accurate dynamic model .”

Yang Heping and Anderson White exchanged glances.

Anderson White frowned and said: "Professor Pang, as far as I know, atom probe chromatography has high requirements on samples. For example, when collecting data, the sample analysis room must reach ultra-high vacuum, and the sample must be cooled to a low temperature to reduce the The thermal vibration of the atoms in the sample, the sample is connected to positive high voltage as the anode, so that the atoms at the tip of the sample are in a state to be ionized. After superimposing pulse voltage or pulse laser on the tip of the sample, the surface atoms will be ionized and evaporated. The evaporation is measured by time-of-flight mass spectrometer The mass-to-charge ratio of the ion is used to obtain the mass spectrum peak of the ion to determine its element type. The position-sensitive probe is used to record the two-dimensional coordinates of the flying ion on the surface of the sample tip, and the longitudinal coordinates of the ion are determined by the layer-by-layer accumulation of the ion in the vertical direction. , and then give the three-dimensional space distribution images of different element atoms..."

"Moreover, the so-called EM (ehod) method is currently used to determine the precipitated phase in the material. The EM method requires that the distance between the solute atoms in the precipitated phase is smaller than the distance between the matrix atoms, and the atomic concentration is higher than that of the matrix. Therefore, when we carry out material determination, we must choose appropriate limiting parameters. For example, the maximum distance Dmax and the minimum number of solute atoms Nmin between the nearest neighbor solute atoms can identify the precipitated phase. In the field of biology, the nearest neighbor solute atoms of many biological macromolecules The spacing is usually larger than Dmax, and the minimum number of solute atoms is smaller than Nmin, so it is simply impossible to measure accurately."

Pang Xuelin smiled slightly, and was well prepared for Anderson White's questions. He said, "Professor Anderson, it's actually very simple. Take protein as an example. We can encapsulate the protein into a glass capsule with a wall thickness of only about 50 nanometers. Use an electric field to cut off the outermost layer of the glass capsule, and release the protein one by one in atomic order. Finally, the structure of the protein is completely restored in 3D on the computer, and it complements and perfects the existing three-dimensional model of the protein. In addition, we also A new method can be used to analyze the solute element atoms. For example, we can set a threshold value of the solute atom concentration, and we can judge the area where the solute element atom concentration is greater than the given threshold value as the precipitated phase. In this case, the It solves the accuracy problem that is easy to occur in data analysis, and even through this method, we can also accurately measure the solute atoms in the mixed solution, and then analyze the movement rules of the biological macromolecular structure..."

Anderson White looked at Yang Heping in surprise. The fields of these two experts often use APT technology. They are well aware of the current limitations of APT technology in use, and the proposal proposed by Pang Xuelin This method undoubtedly opened a new door for the development of APT technology.

At this time, Yang Heping said: "Professor Pang, what about the data analysis software, the current data analysis software of APT technology on the market is basically aimed at hard materials, and there is no such thing as biological macromolecular materials."

Pang Xuelin smiled and said: "Leave this to me, and you can be responsible for the hardware. I'm sure that after the dynamic APT technology comes out, it will greatly promote the development of biology, and even have great impact on the fields of material science and fluid mechanics." I don’t know if you are willing to join in.”

Yang Heping and Anderson White looked at each other, laughed and said, "Of course!"

More than half of the reason why they chose to join Qiantang Lab was because of this young genius in front of them.

Now that Pang Xuelin has proposed a very promising project, they are of course willing to cooperate.

And once this project is successful, selling equipment and patents alone, among other things, may bring them a lot of wealth.

After all, according to Pang Xuelin's description, dynamic APT is of great significance. As long as it can be successfully made, I am afraid that the world's top laboratories will wave their money and line up to buy it.

As for whether they could succeed, they didn't think much about it at all.

Today in academia, there is a so-called Ponzi's law.

As long as Pang Xuelin is optimistic about and willing to join the project, it will surely achieve great success.

This kind of statement with a bit of blind worship can be widely circulated in the always rational scientific community, which is enough to show Pang Xuelin's influence.

Especially now that the Golden Dragon battery project has achieved great success, Pang Xuelin's influence both in academia and in the world is rising at a very high speed.

Next, Pang Xuelin discussed with Yang Heping and Anderson White about the research and development direction and route of the dynamic APT technology, and it was not until the evening that he was ready to leave and go home.
