Watching Zhizi drive Alice away, Pang Xuelin returned to the room and found that Qi Xin had fallen asleep, he smiled, lifted the quilt and got into the quilt.

Sleep until dawn.

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

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

Now that he was finally back in safety, he finally relaxed, and he slept soundly.

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 goes out by himself, it may not be as good as Zhizi, so it is better to leave it to Zhizi to handle it with full authority.

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

In the office, Pang Xuelin retrieved the papers related to organ cloning technology from the system and skimmed through them cursoryly.

There are more than 20 papers related to this technology, including stem cell directional induction, in vitro differentiation of organs and tissues, in vitro maintenance technology of organs, etc., each of which is at least equivalent to the CNS level of papers, and three or four of them have even reached the Nobel Prize level.

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

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

At present, whether it is Qiantang Laboratory or Jiang University, Pang Xuelin does not have a suitable biomedical research platform, and he can't find a suitable excuse to send out the paper.

In addition, if Pang Xuelin wants to intervene in biomedical research, he must find a suitable platform.

After a moment of silence, Pang Xuelin said to MOSS: "MOSS, help me investigate the current research and progress of atomic probe tomography (APT)." ”

"Okay, Professor Pang!"

Although Pang Xuelin did not draw dynamic atom probe chromatography (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 spending the morning in the office and finding the information he wanted through MOSS, Pang Xuelin got up and went to the Qiantang laboratory.

With the official establishment of the aerospace aircraft and electromagnetic orbit space launch system projects, the construction of the 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 the Qiantang Laboratory have settled in successively.

The Carbon Nanomaterials Research Center and the Golden Dragon Battery Research Center, which were originally located on the Yuquan campus of Jiangda University, have also been relocated.

The new generation of flying blade material black box reaction equipment developed by Wanyi and others has also been installed in the Qiantang laboratory, and the output has increased by more than ten times compared with the previous equipment in the 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, and only then can the electromagnetic catapult track project enter the formal construction stage.

"Professor Pang, at present, the supercomputing center, carbon nanomaterials engineering laboratory, Jinlong battery research center, nanomaterials and device research center have completed the construction work, and it is expected to officially start operation within one to two months, and in the next six months, the key laboratory of 3D micro-nano processing and characterization research, the condensed matter physics laboratory, and the superconducting materials research center will also be completed one after another, and then you can show your talents."

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

Xu Xingguo had previously served as the dean of the School of Materials Science and Engineering at Jiangxi University, and the cooperation between the two has been very pleasant.

After the preparation of the Qiantang Laboratory began, he was pulled over by Pang Xuelin to take over the position of director of the Qiantang Laboratory.

Pang Xuelin nodded, pondered for a moment, and asked, "Professor Xu, you will bring Professor Yang Heping, Director of the Research Center for Nanomaterials and Devices, and Professor Anderson White, Director of the Key Laboratory of 3D Microfabrication and Characterization, later, I have a more important project that I need to discuss with them." ”

Xu Xingguo was slightly stunned, nodded and said, "Okay, then let's go to the conference room in Building 2 first, and I'll call them." ”

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

After everyone sat down in the conference room, Yang Heping took the lead and said, "Professor Pang, did you suddenly come to us for something?" ”

Yang Heping previously worked at Stanford, is a tenured professor in the Department of Materials Science and Engineering at Stanford University, deputy editor-in-chief of the top journal in the field of nanomaterials, "Nano Express", director of the Bay Area Nano Alliance, and has deep attainments in the field of carbon nanotube CMOS devices.

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

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

So Corton Walker recommended him to Pang Xuelin.

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

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

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

There are two different micromanufacturing process methods for micro-manufacturing, one is lithography technology, LIGA technology, bonding technology, packaging technology and so on based on semiconductor manufacturing process, these process technology methods are relatively mature, but there are generally problems such as single processing material and expensive processing equipment, and can only process two-dimensional or quasi-three-dimensional micromechanical parts with simple structure, and cannot process complex three-dimensional micromechanical parts; The other is mechanical micromachining, which refers to the micromachining technology formed by traditional processing technologies such as machining, special processing and other forming technologies, which can be processed with three-dimensional complex surface parts, and the processing materials are not restricted, including micro-grinding, micro-turning, micro-milling, micro-drilling, micro-stamping, micro-forming, etc.

Nanofabrication, on the other hand, refers to the manufacturing technology of nanoscale structures, devices and systems with specific functions, including nanoimprint technology, scribing technology, atomic manipulation technology, etc.

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

Pang Xuelin said: "Professor Yang, I have summoned you and Professor Anderson over today, I have a more important task to hand over to you. ”

"What job?"

Yang Heping said.

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

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

"Dynamic Atom Probe Chromatography?"

Yang Heping and White couldn't help but be slightly stunned.

Yang Heping said: "Professor Pang, atomic probe tomography technology, I know, the technology that provides 3D tomography images and chemical identification at the atomic scale is mainly for hard materials, and the application field has expanded from conductive metal materials to semiconductor materials and non-conductive ceramics and other materials. ”

Pang Xuelin smiled: "Dynamic atom probe chromatography technology is used to analyze the movement of atoms in the time range from femtosecond to microsecond of biological macromolecules, so as to construct the atomic structure of proteins, RNA and other biological macromolecules, and provide a more accurate description of the biodynamic functions of these molecules." In addition, this technique can be used to analyze the thermal vibrations of atoms in hard materials and the behavior of molecules in fluids to build a more accurate dynamic model. ”

Young and Anderson White glanced at each other.

Anderson White frowned and said: "Professor Pang, as far as I know, atomic probe chromatography technology has high requirements for samples, for example, when collecting data, the sample analysis room must reach ultra-high vacuum, the sample is cooled to low temperature, so as to reduce the thermal vibration of the atoms in the sample, the sample is connected to positive high pressure as an anode so that the atoms at the sample tip are in a state to be ionized, and after the sample tip is superimposed with a pulsed voltage or pulsed laser, the surface atoms will ionize and evaporate, The mass-charge ratio of the evaporated ion was determined by time-of-flight mass spectrometry to obtain the mass spectral peak of the ion to determine its element species, and the two-dimensional coordinates of the flying ion on the surface of the sample tip were recorded with a position-sensitive probe, and the longitudinal coordinates of the ion were determined by the accumulation of ions in the longitudinal layer, and then the three-dimensional spatial distribution images of different element atoms were given......"

"In addition, the so-called envelop method (EM) is used to determine the precipitated phase in materials, which requires that the distance between the solute atoms in the precipitated phase is smaller than that between the matrix atoms, and the atomic concentration is higher than that of the matrix atoms, so we must select the appropriate limiting parameters when determining the material. In the field of biology, the spacing of the nearest neighbor solute atoms of many biological macromolecules is usually greater than Dmax, and the minimum number of solute atoms will be less than Nmin, so it is impossible to accurately determine it. ”

Pang Xuelin smiled slightly, prepared for Anderson White's question, 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, take it out, cut off the outermost layer of the glass capsule with an electric field, and release the proteins one by one in atomic order. Finally, the structure of the protein is completely restored in 3D on the computer, and the existing 3D model of the protein is supplemented and improved. In addition, we can also use a new method to analyze solute atoms, for example, we can set a threshold of solute atom concentration, and any area where the concentration of solute element atoms is greater than a given threshold can be judged to be the precipitated phase. In this way, the problem of accuracy that is easy to occur in data analysis is solved, and even through this method, we can accurately measure the solute atoms in the mixed solution, and then analyze the movement law of the biological macromolecular structure......"

Anderson White glanced at Yang Heping with some surprise, these two big bulls are in the field to use APT technology regularly, they are very clear that the current limitations of APT technology in use, and the method proposed by Pang Xuelin undoubtedly opens a new door for the development of APT technology.

At this time, Yang Heping said: "Professor Pang, what about the data analysis software, the data analysis software of APT technology on the market is basically for hard materials, and there is no one for this kind of biological macromolecule material. ”

Pang Xuelin smiled: "I'll do this, you just take care of the hardware, I'm sure that after the dynamic APT technology comes out, it will greatly promote the development of biology, and even have a very big impact on materials science, fluid mechanics and other fields, I don't know if you are willing to join in." ”

Yang Heping and Anderson White glanced at each other and laughed, "Of course I do!" ”

The reason why they chose to join the Qiantang Laboratory was that most of them came to the genius boy in front of them.

Now Pang Xuelin has proposed a very promising project, and they are certainly willing to cooperate.

And once this project is successful, if nothing else, just selling equipment and patents will probably 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 banknotes and queue up to buy it.

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

Nowadays in academia, there is a so-called Ponzi law.

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

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

Especially at the moment when the Golden Dragon battery project has achieved great success, Pang Xuelin's influence in the academic community and in the world is climbing at a very high speed.

Next, Pang Xuelin discussed the research and development direction and route of dynamic APT technology with Yang Heping and Anderson White, and did not prepare to leave home until the evening.
