Great Country Academician

In the office, Xu Chuan got a complete report on this electrochemical synthesis of graphene.

From the complete synthesis process to the various test reports and index parameters of the final synthesized graphene, it is complete.

After briefly browsing the synthesis process, his eyes fell on graphene's test report and index parameters.

[Graphene powder A (can be colloidally dispersed), number of layers: 1–5 layers (controllable), average thickness: 2nm, graphene sheet size: 5–50μm (controllable), purity (carbon content): about 97wt% 】

[Graphene powder B (lower cost), number of layers: 2–10 layers (controllable), graphene sheet size: 20–200μm (controllable), specific surface area: about 50 m2/g, purity (carbon content) : About 98wt%]

【Graphite film A】

Data items one by one, as well as the index parameters obtained from the test, flashed across Xu Chuan's eyes.

Graphene products are generally divided into two forms: graphene powder and graphene film.

Graphene powder is currently mainly used in new energy, anti-corrosion coatings, composite materials, biosensors and other fields, with a wide range of applications.

Graphene films are mainly used in flexible displays, sensors, electronic devices and other fields, and their application scope is relatively small.

But his main focus fell on graphene films.

Because compared to graphene powder, graphene films have a broader prospect.

Whether it is flexible displays, sensors, or graphene electronic devices, they are all more sophisticated and expensive products.

Moreover, it is particularly difficult to produce large-area high-quality graphene, and the market that can be created is even larger.

[Graphite film A: Density: 0.3–2.2 g/ml (adjustable), transmittance: 99.98-99.7% (number of layers): thickness: 1– 50μm (adjustable) thermal conductivity: 4837.21 W/mK, electrical conductivity Ratio: 10^6, tensile strength: 1 - 50 MPa, internal carrier mobility: 2×10^5cm^2/Vs]

【Graphite film B:.】

From the data of six groups of controlled test experiments, this graphene film prepared by electrochemical methods is quite excellent in various parameters and indicators.

Whether it is light transmittance, thermal conductivity, electrical conductivity and tensile strength, it can be said to be top-notch among graphene films.

This level of graphene film has a relatively wide range of applications.

For example, the heat dissipation in mobile phones or computers.

Nowadays, after the great leap forward in mobile phone performance, there is actually no shortage of performance, but mobile phones need to generate heat to release performance, and the stronger the performance of the SoC, the higher the heat generation.

However, every inch of space is precious in the internal design of mobile phones. "How to conduct heat" in the process of releasing the performance of mobile phones is the key that smart phones need to solve now.

With a thermal conductivity of up to 4837.21 W/mK and nearly 5,000, its thermal conductivity exceeds all thermal conductive materials on the market.

Generally, mobile phones or computers use thermal conductive silicone grease or thermally conductive silicone sheets as heat dissipation materials.

The thermal conductivity of these two materials is only about 10W/mK. Even high thermal conductivity silicone is only about 15-45W/mK.

Better mobile phones use more advanced and more expensive thermal conductivity solutions consisting of phase change thermal conductive sheets, thermal conductive graphite sheets, VC vapor chambers, and thermal conductive silicone gel.

But even the graphite sheet with the best thermal conductivity inside has a thermal conductivity of only 1500-2000w/m.k.

This number is exaggerated enough for conventional heat dissipation materials, but compared to graphene, which is nearly 5,000, the performance is very low.

It has to be said that the results of the Chuanhai Materials Research Laboratory this time, even without him, are enough to make this research institute one of the top materials research institutes in the world.

After all, this is a technology that can industrially mass-produce high-quality graphene materials.

Xu Chuan naturally attended the celebration party in the evening.

After all, for the Chuanhai Institute of Materials, the ownership of the results developed by its researchers belongs to the institute.

The graphene technology developed by Yan Liu and other researchers this time, whether it is a patent or something else, basically belongs to research institutes and laboratories.

These are industry practices in the materials industry and are stipulated in contracts, so there is nothing controversial about them.

As for researchers who have made achievements, they generally receive project bonuses and one or several papers written during the research process.

Of course, in many cases, after researchers produce results, considering project confidentiality, patents, other related projects, etc., the paper may be kept in their own hands and delayed for a period of time before being released to the public.

Or sometimes it may even happen that it cannot be disclosed or even applied for a patent.

In this case, the institute or laboratory will naturally compensate the corresponding researcher in other aspects.

Just like this time, after taking into account the particularity of high-quality graphene, Xu Chuan talked to Yan Liu. There is a high probability that the paper will be postponed or not published at all.

But the compensation is generous.

To put it simply, in addition to promotion, salary increase and an additional bonus, Yan Liu can obtain 2% of the net income after mass production of graphene.

Even though the figure of two percent is small, the market for high-quality graphene is quite vast, with almost billions of meters of gold every year.

Although Chuanhai Materials Research Institute cannot monopolize all the market, with the outflow of high-quality graphene, this market will gradually expand over the years.

In the future, the market for high-quality graphene may not be in the billions, but may be tens of billions or even hundreds of billions.

Even if Chuanhai Materials Research Institute can only occupy half or even one-third of the market, the dividends Yan Liu can receive are calculated in units of tens or hundreds of millions.

In fact, for most research institutes, under normal circumstances, even if ordinary scientific researchers develop a certain material or patent that can bring high profits to the research institute by chance, it is difficult to get a share of the profits. .

After all, you receive funds from the institute and use the equipment of the institute for your research, and the contract also stipulates the ownership of these things.

But for Xu Chuan, he has always been generous in this regard.

And it is definitely worthwhile to use 2% of the profits to bind Yan Liu to the Chuanhai Materials Research Institute to prevent other research institutes from poaching and leaking the synthesis process and method of graphene.

Of course, this also has the effect of buying horse bones for thousands of dollars.

When other scientific researchers know about it, they will definitely work hard to conduct scientific research.

And every time a result is produced, even if a part of the profit is given to researchers, the institute will still make the bulk of the profit.

It's totally worth it.

Naturally, Yan Liu happily accepted this compensation.

Although I couldn’t publish my paper, I got promotion, salary, bonus, and even dividends I didn’t expect.

If he hadn't been so shameless, he would have really wanted to shout: 'Sichuan God is awesome! Sichuan God is awesome! ’

After all, scientific researchers work hard to conduct experiments and publish papers, isn't it just to enhance their reputation, get promotions and salary increases, and earn more money.

Although there are ideals, you have to find your own bread before chasing your ideals, right?

This time, he got it right in one step and received unexpected dividends. If he is not satisfied, then it is really unjustifiable.

After briefly handling the work brought about by the mass production of graphene, Xu Chuan found the master Xiong Fan Pengyue and handed him a USB flash drive.

"This is a research result on a strongly correlated electronic system, mainly focusing on the strong diamagnetic mechanism of the KL-66 material previously studied in South Korea."

"You find a few modelers who are definitely 'clean', use it to build a targeted mathematical model, and map it into the high-temperature copper-carbon-silver composite superconducting material system."

"This work is important and must be kept confidential."

Xu Chuan handed over the USB flash drive in his hand, which contained his research results some time ago.

Although the problem of the strongly correlated electronic system is still stuck in the last step, the research on the strong diamagnetic mechanism of KL-66 material has been completed.

The remaining work is to use this research to build a mathematical model, and then introduce high-temperature copper-carbon-silver composite superconducting materials to see if the critical magnetic field of the superconducting materials can be improved on the original basis.

In the KL-66 material, its strong diamagnetic mechanism comes from the replacement of ions in the lead phosphate insulation network by copper, which generates stress and is simultaneously transferred to the Pb of the cylinder, causing deformation of the cylinder interface, thus creating a magnetic trap.

To explain it mathematically, the two branches of the Fermi arc state electron connecting the c-axis break the inversion symmetry, which in turn causes the Dirac cone to split into two Weyl nodes with opposite chirality, leading to non-trivial quantum Phenomenon.

If you can't understand this, in the simplest terms, it means putting a massive star into the solar system, replacing planets such as Jupiter or Saturn.

And because of the strong gravity of the star, this new star will stretch space and time, form another gravitational field, and change the trajectory of other celestial bodies in the solar system.

The magnetic trap in KL-66 material has a similar effect. It forms its own unique additional magnetic moment. The direction of the magnetic moment is opposite to the direction of the external magnetic field, forming Larmor precession phenomenon and possessing strong diamagnetism.

This phenomenon is theoretically applicable to many materials, especially semi-metal and semi-organic combination materials.

However, how to control the atomic level unit to form a unique additional magnetic moment is a difficult problem.

This requires further experiments to prove it.

But at least, before he conducts the experiment himself, the relevant mathematical calculation model must be made first.

It has to be said that if there is another breakthrough in the critical magnetic field of superconducting materials this time, and miniaturized controllable nuclear fusion and aerospace engines can be produced, it will really be a great contribution to South Korea.

If it weren't for the KL-66 material they produced, it would be no less difficult to increase the critical magnetic field of a superconducting material.

Although the purpose of their making this material may not exist, the value inside is real.

Not even its own scientists have discovered it.
