The richest man starts with a blind box

Yang Yunhe's imagination was running wild, while Tong He had already begun to show Boss Huang this brand new material.

Just like the previous experiment at the beginning, Jiashen No. 1478 sample turned into a solid metal immediately after being powered on, and once the power was turned off, Jiashen No. 1478 sample turned back into a golden yellow liquid in an instant, and the whole The conversion process takes less than three seconds, which is very fast.

On the other hand, although the special characteristics of the Jiashen No. 1478 sample had already been known from the documents and materials, Boss Huang couldn't help swallowing when he really saw the facts in front of him.

In Boss Wang's opinion, the practical value of Jiashen No. 1478 sample is probably not much lower than that of black gold, because it is a very perfect liquid metal.

When most ordinary people form the concept of liquid metal, it comes from a movie called Terminator 2.

In this movie, the Terminator who can freely switch from a business form to a robot form can be said to have blown the heads of countless viewers. This seems to be a kind of metal that only exists in science fiction works.

But in fact, liquid metal was invented as early as the 60s. After Cameron himself officially saw liquid metal, he added the idea of ​​liquid robots to his own movies.

However, liquid metal has been invented for such a long time, but it has almost never received any serious applications. The key is naturally that liquid metal is not as perfect as described and described in the movie.

At this time, most of the liquid metals invented by humans are in a liquid state under normal conditions, and they can also exhibit the characteristics of metals, but they cannot be hardened... Among them, mercury is the best example, he is a natural liquid metal .

Although such liquid metal is also useful, it is extremely useless.

Of course, there are still some liquid metals that can be hardened. For example, in 2015, some researchers in Huaxia developed a liquid metal that can be liquefied into metal after swallowing a small amount of material. It is a breakthrough of liquid metal.

But the actual usage scenarios of this kind of hardening are actually not high. First of all, this kind of hardening is one-time, and it is difficult to return to the liquid state after hardening.

Even if it is possible, a lot of chemical operations are required in the use room. In the actual use process, it is obviously impossible to give you so much space and time for operations.

In addition, after solidification, liquid metals like this are generally not very hard, basically softer than silver, and some are even like plasticine, which can be kneaded into various shapes by hand.

Of course, such a soft feature can also have certain application scenarios, but after all, metal still needs to be hard to be more effective.

Now, Jiashen No. 1478 sample perfectly solves this shortcoming. In the hardened state, the hardness has even reached a level of diamond, but it still has a very high degree of ductility like liquid metal. The characteristics of this material itself It's just perfect.

In other words, this material can switch between solid and liquid at any time only by controlling the energized state. Huang He can already imagine countless application scenarios with his eyes closed.

...

For example, it is used in the aerospace field, and various fields that require rapid prototyping.

It can even be applied in terminals, because it can solve many problems of folding screen terminals.

"Okay, that's really great." Boss Huang praised sincerely.

Yang Yunhe on the side also applauded. He was also shocked by the look of this liquid metal, but at the same time he was a little bit disgusted, thinking that in his opinion, this kind of metal is also a bit tasteless, that is, it can only be maintained in a solid state by energizing it all the time. This cannot be used in many environments.

As a result, in the next second, Boss Huang directly asked, "Is there any way for him to maintain a solid state for a long time without power on?"

"Yes!" Unexpectedly, Tong He said very simply, "After our research, we found that in the liquid state, this kind of material can start to solidify only by passing through the radiation field. It's just that the speed is very slow, and it takes about 24 hours to complete. Completely solidified, but such solidification will not return to a liquid state, at least all of our samples have not returned to a liquid state."

"Okay, very good!" Boss Huang's face was full of excitement. If it can be cured for a long time, it will undoubtedly greatly expand the usage scenarios of Jiashen No. 1478 sample.

But Tong He’s surprise to Boss Huang was more than that. Tong He continued to say, “During the experiment, we found that the characteristics of Jiashen 1478 samples are also different with the different voltages applied!”

"For example, when it is normally given a voltage of 220 volts, the characteristics it exhibits are quite hard."

"But if the applied voltage is lower than 2 volts, the hardness will drop to the point similar to that of graphite, but the resistance will increase to an extremely high level, becoming an almost non-conductive insulator!"

"Conversely, if the voltage is increased to 1000 volts, the hardness will exceed that of diamond, and the conductivity will be three times that of copper. And if the voltage is increased to more than 10 volts, then we can get a hardness that is equal to that of diamond. Twice, and at the same time very close to superconducting metals."

"According to our current summary, we found that the higher the voltage, the higher the hardness and the lower the resistance of the Jiashen 1478 sample. On the contrary, the lower the voltage, the lower the hardness and the higher the resistance!" Tong He concluded.

"Doesn't that mean that we can directly control the various properties of this material by energizing the material with voltage!" Boss Huang licked his lips. A crazy upgrade! "

"Not only that, boss, we also found something more interesting later!" Tong He chuckled, and the expression on his face suddenly became more excited, like a child eager to present a treasure.

"Actually, this is the result of only passing through one electrode, so in the later experiment, I suddenly had a whim, what would happen if it was powered directly through two electrodes?"

"So I gave it a try!" Tong He said, manipulating another robot arm, piercing an electrode into the liquid sample of Jiashen No. 1478, and then energizing the two electrodes at the same time.

"First, we applied a voltage of 220 volts to the two electrodes at the same time!" Tong He said, and then the sample of Jiashen 1478 began to solidify rapidly, but there was almost no difference between the subsequent reaction and the previous reaction, and they were all in the same state.

...

Of course, this is not what Tong He wanted to show Boss Huang, so he immediately announced, "Now, I will adjust the voltage of electrode A to 230 volts, while the voltage of electrode B will remain unchanged, forming a 10 volt voltage between the two." voltage difference!"

Then, a miraculous scene happened.

The sample of Jiashen No. 1478, which was not moving at all, actually began to tremble at this moment. Don’t bring them into the glass container, which is also shaking constantly. In this constant tremor, the entire sample of Jiashen No. 1478 is actually so direct. began to spin slowly.

The rotation speed is not high, much slower than that of the donkey mill, but there is no doubt that the entire sample of Jiashen 1478 began to rotate.

Seeing this, Boss Huang blushed again.

Some people may think that it is not unusual for a metal to rotate. After all, anyone who has studied the principles of generators or motors knows that when the coil in the magnetic field is energized, the coil will start to rotate at high speed.

In the same way, when the coil starts to cut the magnetic induction line driven by external force, it will generate a steady stream of electric power. This is the basic operating principle of motors and generators. Now this Jiashen 1478 sample is spinning , and nothing surprising, the motor has long been able to move.

But the magic and preciousness is precisely here. After hundreds of years of human beings inventing the electric motor, the driving principle of the electric motor has not changed at all, and it is still the principle of electromagnetic response back then.

But now, although there is still electricity here, there is no magnetic field.

In other words, mankind has achieved a historic breakthrough, that is, it can directly drive objects without any magnetic field when only electricity is applied. The original motor structure, explore a new motor structure.

Of course, seeing the rotating sample of Jiashen No. 1478, Huang He couldn't help asking, "Can this thing rotate faster?"

"Yes!" Tong He nodded and said, "The Jiashen 1478 sample uses the voltage difference between the two electrodes to push the inside of the metal to start rotating, so as long as the voltage difference between the two is larger, the rotation will be faster."

"For example, at this time, if we reduce the voltage of electrode B to 0 and only maintain a energized circuit, then the whole speed will be like this...but it needs to change a container." Tong He said, and he entered the glass cover himself. Inside, the original sample was taken out, and replaced with a disk-shaped container, which also contained the golden-yellow Jiashen No. 1478 sample.

Then through a bearing, the container is fixed on an iron rod, which basically simulates the state of a car tire.

Afterwards, Tong He turned on the electricity, and the entire Jiashen No. 1478 sample began to rotate crazily, at a speed that was almost the same as the rotation speed of a car's tires.

"Experiments have shown that under a voltage difference of 220 volts, the speed of Jiashen No. 1478 sample can reach about 6000 revolutions per minute at the fastest, and if the voltage difference is continuously increased, the speed can also be continuously increased. In our experiment The fastest speed achieved is as high as 102 million revolutions per minute."

"However, this rotation speed lasted for less than three seconds, and the bearing could not bear such a high rotation speed, which finally caused Jiashen No. 1478 sample to hit the glass shield, breaking through the three-layer shield in one breath. It almost caused a big accident!" Tong Hexin said with Yuji, "but there is one thing that cannot be denied, that is, the speed can be continuously increased only by continuously increasing the voltage, and the speed is increased in an equal proportion, which surpasses the current All motors!"
