Technology: breaking the hegemony that monopolizes the world

With the gradual turning on of the lights, everyone at the tasting and the audience in the webcast room saw Gu Qing on the podium, standing inside pieces of transparent glass.

Moreover, these transparent glass-like things are still shining with various small green light spots, as if there are special fireflies of various colors inhabiting there.

Boss Gu, who is no longer so young, still doesn't know how to be a riddler.

He pointed to the "glass" around him, sighed, and explained: "You should have seen the Yunjin display made by the nano-display equipment developed by Kyushu Technology before.

In the finals of the "Omnic Crisis" Global Martial Arts Conference, the sky screen made of Yunjin Display had an excellent display effect, and our researchers suddenly thought that AR technology and the nano-display material of Yunjin Display should have a wider field of view. There is no room for improvement, so I worked crazy overtime for hundreds of days and nights, and finally developed this theater system.

Well, I personally think this system is quite suitable for watching movies. The ultimate sense of experience makes people feel immersive.

I wonder if you had this kind of experience when you just watched the short film? "

Obviously, the people sitting under the stage are all calm executives of big companies, but when Gu Qing asked this question, someone actually answered loudly: "It's exciting! Mr. Gu, can you show us again?"

"Watch it again? With the combined net worth of all my friends sitting here, I am afraid that if you watch it for ten seconds more, you will waste hundreds of millions for everyone. Friends who want to watch the video can ask Xiezhi for the file now, and friends in the webcast room can also Click on the personal center of the official account of our Kyushu Science and Technology live broadcast on the whole network, and this video should have been released by now.

Of course, it's not that I don't want to waste everyone's time. It's just that so many products have already been dismantled, and the time it takes to install and debug is much longer than the time we just entered the system to watch movies. "

The kind explanation resolved the embarrassment of the executive.

But what Gu Qing said afterwards made everyone's hearts tighten.

"As a technology tasting meeting, because some documents are still going through the review and filing process, I can't show you the actual product at present, so I will ask the technical department to show this set of technology, and strive to make it impossible for everyone to touch it. In the case of the actual product, you can see the demonstration and general situation of this product.

These display parts next to me are reserved for this purpose. "

After saying this, Gu Qing stretched out his right hand and pointed at the glass plate in front of him.

"Like this graphene super copper motor."

Then he pointed to the glass plate in the front left and said, "For example, this solid-state battery technology made of graphene materials."

He continued to point straight ahead and said, "Silicon-based chip modules with large size and multiple stacks that can independently support artificial intelligence computing."

Without stopping his fingers, he pointed upwards.

"Regional special network communication, dual-satellite system positioning technology."

Then, he waved his hand around randomly, and the pieces of glass lit up like dominoes one by one.

Rigid/flexible robotic arms, various components made of polymer materials, chip system installation platform, Kyushu mecha, satellite devices of various shapes, and even the appearance of rockets, and the distant corners are like space stations blurry image.

If others open up their family background, it is called showing off their wealth.

But when Gu Qing revealed his family background, these elites with hundreds of millions of net worth at the tasting meeting had already become "bumpkins" at this time.

After all, no one at the scene had a net worth comparable to Gu Qing's.

Under Mr. Biati Wang's expectant and somewhat fearful eyes, Gu Qing pointed his right hand at the glass plate in front of him, and said to the motor pattern: "Today we also have a lot of things to do and a little time, so we don't want to be a joke. , Let me introduce to you the graphene super copper motor developed by Kyushu Technology.

The concept of graphene application has been widely publicized in recent years. Graphene can be used in almost everything. I even heard from some technicians in our company that there are still companies in the market that are developing graphene toothpaste and graphene beauty instruments. I can't help feeling that the application of new materials is simply a harvest of new knowledge for ordinary users' wallets.

Of course, as a not-so-smart man in science and engineering, I think graphene is still very useful. For example, our graphene super copper motor uses the advantages of graphene.

From a chemical point of view, each carbon atom in graphene is connected to three adjacent carbon atoms through a σ bond, and each carbon atom has only one unbonded π electron, forming a large π conjugated structure with the surrounding atoms , so that π electrons can move freely in the crystal structure.

The physical explanation is that the unique π-electron cloud conduction of graphene makes the carriers less susceptible to scattering during conduction, and has the characteristic that the mass tends to zero, which can be transported at the Fermi velocity () to achieve extremely high loads. Carrier mobility, even if the carrier concentration of graphene is not large.

Therefore, graphene materials have excellent electrical conductivity.

At the same time, graphene has two thermal conduction mechanisms of electron movement and phonon heat conduction. The connection between carbon atoms in graphene is C-C covalent bond. This stable lattice structure makes electrons in orbit, or phonons in the lattice. There is very little scattering, so it has excellent thermal conductivity.

Moreover, graphene has excellent impermeability, high specific surface area and high aspect ratio due to its special material structure, which can effectively prolong the path for oxygen and water vapor to penetrate the polymer substrate and greatly reduce the pass rate.

In this way, graphene materials also have strong corrosion resistance.

In addition to these, graphene has many applicable material fields, as long as they use graphene material technology, without exception, they can have better performance than other materials in this material field.

It seems to be very versatile, but the practical application is that there are thousands of researchers who cannot stop us.

For example, the graphene material itself cannot simply adhere to the substrate, it must pass through the polymer substrate, and the polymer substrate must be clean enough.

Our experimenters have found in experiments that graphene materials can indeed improve electrical conductivity at the micron level, but not at the centimeter level.

So we chose to electroplate graphene on the surface of the copper wire. From the effect point of view, the thermal conductivity and oxidation resistance of this technology are good, but it is only good.

Because of this, the cost of the motor will become more expensive, while the stability is insufficient, and maintenance is also very troublesome. "
