β particles, in the decay of matter, are the release of high-speed electrons, the speed can reach 99% of the speed of light, with high speed and high energy, is an ideal source of electricity.

A large number of β particles are harmful to the human body when running at high speed, so the alloy separator film is coated on the micronuclear battery, and the alloy is encapsulated on the outside of the separator, which is to ensure the safety of the battery to the greatest extent.

Xu Limin joked on stage: "Many of the people who came to the press conference today are ladies, and I am here to tell my female compatriots that in the future, your boyfriend will propose to you, and don't buy diamonds or anything." In our laboratory, we have been able to synthesize the most perfect diamonds in the world, and they are as big as you want, and diamonds are not only eternal but also easy to make. ”

The audience burst into laughter.

The female anchor of the live broadcast looked at the diamond ring in her hand, and was quite anxious, Pangu Technology has the ability to produce flawless diamonds, fortunately, their "diamond" is the energy source of the micro-nuclear battery, otherwise it will not only be the lithium battery industry that will be rushed into, but the entire jewelry industry will be impacted.

The solidification of carbon-14 into crystals is the first step in a micronuclear battery.

Constance and his entourage took out the paper on Pangu Science and Technology in "Natural Physics" and began to compare each step of the experiment.

Xu Limin stood in the center of the stage, calm and confident.

"The second advantage of the C14 micronuclear battery that I just mentioned is that it is very powerful. Where does this energy come from, and how do we rely on the internal structure of the battery to collect it? ”

Constance and the others were engrossed in staring at the podium and the big screen, knowing that this was the core of Pangu Technology.

On the other side, in the United States, the headquarters of Tesla in California, as well as the headquarters of Apple and Google, the technology bigwigs did not care about the thirteen-hour time difference, stayed in front of the screen, downloaded Xia Guo's live broadcast software, and watched it

Super Xiaochu is connected to the big screen at the press conference, and she will intelligently play slides or animations automatically according to Xu Limin's explanation.

At this point, a simple decay equation is displayed on the big screen: (top 14, bottom 6) C14--& gt; (upper 14, lower 7) N14 + (upper 0, lower -1) e.

Xu Limin said: "A basic physical common sense, the energy contained in an electron is one electron volt, that is, 1 EV. Whereas, the amount of electricity contained in an electron is 1.6×10^(-19)C. ”

On the big screen appeared the basic physics formula of the micronuclear battery.

The VIP seats were all physics experts, and the basic principles and formulas were difficult for everyone, but in the audience at the back, many people began to get dizzy.

"Please take care of the level of the students below, I really can't understand it. ”

"Ahh ”

Xu Limin continued to make the principle inference, "Now, we know three other parameters. ”

"One is the half-life of C14 T(1/2) = 5370 years, that is, 1.807×10^11 seconds, and the other is the speed of light c = 2.9979×10^(8) m/s, why do we use the speed of light here. As I have just said, I will emphasize it again, because the β rays spilled by β decay can reach 99% of the speed of light, which is the basis for our micronuclear batteries to be able to stop supplying stable and strong currents. ”

Xu Limin said with a smile: "What we want is electricity, not a nuclear explosion." ”

There was laughter from the audience,

On the large screen, all the known parameters are arranged neatly, waiting to be used to calculate,

Xu Limin said: "In addition, we also know that the molar constant is 6.02×10^23, so we also know that 1g of carbon-14 has 1/14×6.02×10^23 atoms, that is, 4.3×e^23 atoms." ”

"Now let's start the math. ”

Xu Limin turned his head to the big screen, and Super Xiaochu began to arrange the formulas according to Xu Limin's requirements, applying known constants.

Xu continued: "We can know that the decay constant of carbon-14 is 3.835×e^(-12) from the decay constant formula λ=0.693/T(1/2). That is, the chance of decay per carbon-14 atom in one second is 3.835×e^(-12). ”

"1g of carbon-14 has a total of 4.3×e^23 atoms, and we can count from macroscopic statistics that the atoms that decay in one second are λ×4.3×e^23, and about 1.013226×10^18 atoms decay, contributing 1.013226×10^18 charges. ”

Xu Limin said: "As you know, the half-life is meaningless for a certain atom, and our macroscopic calculations can only ensure that the number of 1g of carbon-14 atoms is correct. ”

The explanation continued, but on the live broadcast forum, it had already turned the world upside down.

"Ahh

"All kinds of parameters, all kinds of formulas, all kinds of huge data, physics is really not something you and I can play. ”

Of course, there are also top students, "In fact, it is very simple, that is, to calculate the maximum current that a micronuclear battery can produce through the carbon-14 decay variable." ”

Xu Limin paused and said: "Through the above known conditions, we can know that after the micro-core battery is connected to existing mobile phones, laptops, tablets and other products, it can provide a stable current of 10,000 milliamperes in the laboratory, and a safe and stable current of 5,000 milliamperes. The voltage can be adjusted to 3V-15V through nanometer-level voltage regulating equipment. ”

Theoretically, Xu Limin's expression was perfect, and the scene erupted into a round of applause.

However, the biggest doubt in the minds of Constance and others arises, which is based on the idea that semiconductor materials can capture almost all β rays and apply all β particles in the rays to circuits at once.

This technique is very difficult!

Xu Limin looked at Constance's somewhat constipated expression, of course he knew what he was thinking.

On the large screen, there are multi-layered space-folded silicon carbide crystals, and after magnification, there are dense holes on the top.

This is a 3D model made by Super Xiaochu, showing the state of the silicon carbide crystal in a micronuclear battery.

Xu Limin said: "The laboratory uses an excellent semiconductor material, silicon carbide, which can effectively intercept all β rays in multiple layers after folding its crystal, and we use a special process to etch the crystal color center on the silicon carbide crystal, which can capture and quickly transport electrons. ”

In the 3D animation, electrons are captured by the color center and sent to a silicon carbide circuit, and countless electrons run at close to the speed of light, gathering together like streams to form a huge and surging current.

In this way, the carbon-14 micronuclear battery is presented in front of everyone.

The principle is very simple, and everyone in the European Physical Laboratory understands it.

But the physics involved in it is not something that every laboratory can do.

It is the folding of silicon carbide, the etching of the color center, the capture and collection of electrons, etc., which cannot be achieved by the technology of the European physics community.

Finally, Xu Limin said: "In the end, we encapsulated the carbon-14 micronuclear battery, which became what was shown on the screen. ”
