Super Weapon Swap System

"I just got the news that our Chinese scientists have also independently discovered the copper oxide superconductor in the liquid nitrogen temperature region, and internationally announced its element composition as ba-y-cu-o. this is a major achievement of our Chinese science and technology."

At this time, there was ice and snow outside, and here, in the conference room, the atmosphere of discussion was quite warm. After listening to the introduction of experts, Qin Guan also felt that everyone's efforts in this regard were fruitful.

Although China's overall scientific research strength is relatively weak, it still shows a strong side in some fields. For example, China has always been in a leading position in the field of superconductivity.

Internationally, some scientists have claimed to have obtained superconductors with higher temperatures. Just after they released them, scientists in Han also announced their scientific research achievements and found superconductors in the temperature range of liquid nitrogen, which once again promoted the use of superconductors.

"However, we should also see that for our research, it is absolutely impossible to have this kind of superconductor alone. If we want to be practical, it still has a long way to go." Qin Guan said: "we should constantly improve the upper temperature limit, and it is best to achieve superconductivity when it is tens of degrees below zero."

Superconductors are found at low temperature. Of course, it is more useful if they can realize the characteristics of superconductivity in a higher temperature range. The higher the temperature, the easier it is to be applied in practice.

"Yes, Mr. Qin, you're right, but it's not easy to find this kind of superconductor." a white haired scientist pushed his glasses and said to Qin Guan.

"Yes, so I have some suggestions here. I hope you can verify them in practice," Qin Guan said.

"First, condensed matter. I hope our scientists can develop this field and obtain superconductor oriented materials in this field. There may be great achievements, especially in iron-based superconductors."

Condensed matter is a special quantum state. The research in this field in Han Dynasty is far ahead in future generations. (when Hua Xiong was in college more than ten years ago, a professor did this. Unfortunately, he didn't understand it at that time.)

Qin Guan doesn't need to be specific, just point out the right direction. After all, domestic scientists have accumulated technology, and what they need is the right direction.

In that parallel space-time, Han's main direction is the field of iron-based superconductivity, which is not only the discovery of materials in the laboratory and the improvement of critical temperature, but also widely carried out in experiments, theories and applications, and achieved industrial applications.

Condensed matter? Qin Guan's proposal made them chew seriously. They really didn't pay attention to this direction before. Now, it suddenly shines in front of them. Yes, you can look at it from this aspect!

Looking for high-temperature superconductor materials, on the one hand, requires a theoretical basis, but on the other hand, it also needs to take a chance. Maybe one kind of experiment will come out, or maybe hundreds of experiments are meaningless, just like Edison, who invented the electric lamp in those years, has tested thousands of materials.

"Another aspect is pressurization." Qin Guan continued: "If you want to achieve higher temperature superconductivity, even room temperature superconductivity, the temperature should be increased. Should the pressure be increased? The pressure may be very high by changing their state. As for materials, I suggest you look for materials such as hydrogen sulfide and lanthanum hydride."

When Qin Guan mentioned normal temperature superconductivity, they were stunned. The span was too big!

In fact, after 2020, room temperature superconductivity is really not a dream. When scientists observed the superconductivity of hydrogen sulfide under high pressure, it is only minus 70 degrees, while lanthanum hydride can even achieve superconductivity at minus 23 degrees.

This temperature can be reached by my refrigerator!

At this time, there are extreme conditions. The pressure is quite high. This effect is realized only when it reaches half of the earth's core pressure! Under high pressure, the principle is different.

In the past, superconductivity was a normal structure. An atom was a rigid lattice. When the electrons were moving relative to each other, the electrons collided with the lattice and slowed down, which was resistance. When the lattice cooled, the rigidity was strong enough to become hard enough, and then it propagated in the form of waves.

With the continuous development, scientists have found that hydrogen sulfide can superconduct at high temperature because the lattice can vibrate at high speed at high temperature. However, there must be high pressure to keep the lattice firmly in place to prevent the vibration from tearing it.

In the past, this could not be achieved without pressure. Now, as long as we find the magic weapon of high pressure, it can be achieved.

In contrast, high pressure is easier to achieve than low temperature, and ultra-high pressure vessels in industry have also been mature. In this way, if our researchers identify the direction and find the appropriate scheme, we can easily realize high temperature superconductivity, and our research will lead the whole world!

High voltage? President Qin has never shown great ability in the field of superconductivity, but now, what he said is absolutely constructive!

After a long discussion with a group of experts, Qin Guan left some technical materials and left the conference room. As soon as he came to the door, he received a call from major Yang. The person he wanted had been found and was waiting for him at the door!

So Qin Guan walked to the door with relaxed and happy steps and looked at the young man who had just arrived under the age of 30. At this time, he was looking at Qin Guan curiously.

What's important? Come to me so soon? I'm just a faculty member of the Naval Engineering Institute now.

"Comrade Ma, nice to meet you." Qin Guan looked at the young man in front of him and extended his hand enthusiastically.

Now, he is still unknown, but after that, his name will be well known by military experts all over the world, because the young man in front of him has led the research and development of aircraft carrier electromagnetic catapults in Han country. Moreover, his research and development is more efficient and advanced than that in Eagle country!

It was precisely because of him that the aircraft carrier of Han realized a leap, bypassed the steam catapult and directly developed the electromagnetic catapult.

Compared with the constant failures in the eagle country, President tebupu had to order to give up the electromagnetic catapult and replace it with a steam catapult. However, in the Han country, the success rate was quite high, which greatly increased the confidence of senior naval officials, so that they decided to mount the electromagnetic catapult directly. He was the amazing man!

"The motherland needs you and the Navy needs you. Let's talk about the equipment of warships." Qin Guan cordially took his hand. They are almost the same age. Now they walk together like two brothers.
