Rebirth 2002: Nano Life

In addition to the graphene lithium battery project, Chen Yizhe has other actions next. In November, he acquired two companies one after another in his personal capacity, namely Pengcheng Xinhui Environmental Protection Equipment Co., Ltd., Yide Precision Instrument and Machinery Co., Ltd. Production Co., Ltd.

After a few months, Chen Yizhe, who had made 60 to 70 million yuan just selling graphene, saw that Apocalypse was becoming more and more mature, so he decided to let go. In fact, he originally wanted to acquire a shipyard in Shekou. Unfortunately, the price of the shipyard was 220 million, which was far beyond his expectations. Finally, after considering it for a long time, he decided to temporarily postpone the acquisition plan of the shipyard.

Although several companies seem to have little industrial connection, and it is difficult to have a relationship with Xia Meng Electronics, these are the industries that Chen Yizhe plans to do, and they are also related to a plan he has been planning.

Xinhui Environmental Protection was originally mainly engaged in the filtration business, providing customers with fluid solutions, including various liquid and air filtration, products involving food and beverages, electronic chips, chemical raw materials, and PM2.5 removal.

However, the company's filtration technology is actually not high. After Chen Yizhe spent 7 million yuan on the acquisition, he upgraded the company's technology. After the transformation, two products will be temporarily launched, both of which are liquid filtration products. One of them is the main family day. The other is for industrial or public use.

Chen Yizhe's villa's air and water circulation systems are all built by him, and he still has requirements for the environment, so he can be regarded as an expert in filtering.

As for the treatment method of water filtration, Chen Yizhe's method is actually very direct and simple, converting edible oil into a graphene film, and then attaching it to a traditional filter.

This filter can create microscopic nanochannels that only allow water to pass through, while removing different pollutants, basically filtering out 99.9% of the pollutants. And Chen Yizhe has tested it in severely polluted water. The filter can filter out almost all pollutants in the water, including heavy metals and dioxide, and it can be drunk once filtered.

Chen Yizhe uses this filter to filter the water in his current home, and he has also established a half water circulation system in his home.

After normal tap water is filtered, it is used to boil water for cooking and cooking, while the water entering the sewage pipe for washing dishes, washing, excretion, etc. will be filtered a second time. In principle, although it can be drunk directly, it is always a bit strange psychologically. This water is used for watering flowers, vegetables, washing clothes, etc., and then these are filtered three times...

At present, conventional water purification includes 7-8 steps of filtration and chemical treatment, while graphene water filter can complete water purification in one step. Technically, graphene water filtration is safer and faster, and its cost lies in The production of graphene films, simply put, the cost is completely controlled by Chen Yizhe.

It can be seen that this kind of filter can not only be used in households, but also in large industries such as sewage treatment, and its market is not small. The market will exceed 100 billion in the future, and Chen Yizhe is also planning ahead for this gold industry.

On November 2, Chen Yizhe officially signed a patent general license contract with BOE. The content of the contract is actually similar to that granted by Chen Yizhe to Xia Meng Electronics. BOE enjoys the right to use the patent of electronic paper ink screen worldwide within 5 years. However, Chen Yizhe still reserves the right to implement the patent.

Chen Yizhe did not charge patent licensing fees, but BOE will pay 55 million yuan to Chen Yizhe to purchase ink screen production line equipment, and the latter will be delivered to the first generation of BOE within four months, that is, before March 2. E-paper ink screen production line.

This production line equipment project, Chen Yizhe handed over to Yide Precision Instrument and Machinery Manufacturing Co., Ltd. In addition, a major project that Yide has been working on after being acquired by Chen Yizhe is 3D printing technology.

In later generations, Chen Yizhe has seen "Mission Impossible 4" played by Tang Shuai. One of the plots is that the agent Ethan used 3D printing technology to make a mask that looks like a real person in a short period of time!

As a result, the slightly sci-fi 3D printing technology gave Chen Yizhe unlimited space for imagination: are you going to get married? Print a villa as a new home; want to buy a new car? Print a Lamborghini sports car; Connect it with one hand; I often hear such words at home, "There is no meat in the kitchen, print out two pounds quickly!"…

Of course, most of this kind of life has been realized by Chen Yizhe. 3D printing technology only uses layer-by-layer printing to construct objects, while he uses nanoworms to transform objects in a more microscopic world. The former is just a drive for materials , while the latter can move the material more microscopically and accurately, and even destroy and reshape it!

3D printing technology appeared in the mid-1990s. Before that, in the 1980s, American scientists had invented the first commercial 3D printing machine, which means that it has been 20 years since the concept of 3D printing was proposed. .

3D printing technology was once known as the second wave of the production technology revolution. However, until later generations, no wave has been seen. At most, a few drops of good-looking waves are splashed.

Chen Yizhe's development of 3D printing technology is also to prepare for the mass production of the following graphene chips, not neural network transistors, but simple graphene transistor chips.

Today's lithography machine technology is basically in the hands of Europe and the United States. Many technologies and equipment on the lithography machine of asml in the Netherlands are not actually owned by asml company.

To be honest, Chen Yizhe also has the ability to copy the lithography machine, but it is still difficult to break through its peripheral patents, and if you really want to achieve overtaking, it is better to go out of your own way than to follow in the footsteps of foreign countries. road.

From the very beginning, Chen Yizhe has formulated the road of not taking silicon-based chips and taking carbon-based chips. If he wants to mass-produce graphene chips, Chen Yizhe decided to develop 3D printing technology to realize this strategy after thinking about it.

If you want to produce silicon-based chips, Chen Yizhe decided not to develop 3D printing technology. You must know that the silicon-based semiconductor process uses almost the elements of the entire periodic table. Using printing technology, it must be required that the printer must be able to melt all these materials. , but also to precisely control the ratio to prevent material contamination.

With this level, do you still need silicon to make integrated circuits? Think about what material the printer itself is made of that can melt almost any material.

The technical level of this awesome printer that can produce silicon-based chips is far higher than the technical content of all current integrated circuit processes. It is definitely a technology of the next era, not the same as integrated circuits. dimension.

Chen Yizhe will not do such thankless things, but carbon-based chips are different from silicon-based chips. Ninety-nine percent of the materials of the neural network transistors created by Chen Yizhe are graphite, that is, carbon atoms. Compared with neural network transistors, carbon-based chips are simpler and basically do not require other raw materials, which means that 3D printing only needs to be printed on a single material such as graphene.

Of course, all of this is just the plan in Chen Yizhe's mind. To achieve this, we must first develop a 3D technology that can print graphene materials. Chen Yizhe decided to transform the inkjet printing technology and disperse the graphene powder in a solvent. Form "ink~www.readwn.com~" and then apply a voltage to the piezoelectric ceramic sheet to deform it in time according to the printing needs, squeeze the ink in the cavity to eject it drop by drop, and accumulate layer by layer on the substrate to form a Layer-by-layer transistors, and finally remove solvent stereotypes through post-processing methods such as heat treatment, illumination, and freeze-drying.

The high carrier mobility of graphene makes it very suitable for the preparation of nanoelectronic devices, and inkjet printing is a commonly used convenient and efficient preparation method. The addition of polymers can stabilize the ink, prevent graphene from precipitation and stratification, and can also adjust the viscosity of the ink to make it in a range that is easy to print.

And the most important thing is that the inkjet printing molding equipment is simple, the cost is low, and the operation is simple. It is simply an artifact for the mass production of graphene chips.

Chen Yizhe has produced an inkjet 3D printer in his home laboratory, which produces graphene transistors thousands of times larger than the graphene crystals of neural networks, and the manufacturing process may also be 70 microns.

The structure of graphene transistors is the same as that of silicon-based chips. Compared with silicon-based chips, since the electron mobility of graphene is 200 times higher than that of silicon, the frequency of carbon-based chips is expected to reach 1000GHz. And this characteristic of graphene is also the reason why the computing power of Apocalypse is only inferior to that of supercomputers even if there are only 1 million transistors.

Although there is a difference of thousands of times between the two processes produced by 3D printers and lithography machines, the ultra-high frequency of graphene transistors still makes up for this shortcoming.

Moreover, this 3D printer is only produced by Chen Yizhe according to some materials on the market at this stage, and there is still a lot of room for improvement. As long as the chip process printed by the 3D printer can be controlled within 20 microns, then the graphene chip It can compete with the mainstream chips on the market today.
