Researchers never imagine what they make when they make new metamaterials.

"Researchers have demonstrated the ability to engineer materials that are both stiff and capable of insulating against heat. This combination of properties is extremely unusual and holds promise for a range of applications, such as the development of new thermal insulation coatings for electronic devices. "(ScitechDaily, How Scientists Engineered the Unthinkable With New Hybrid Materials)

The researchers worked with a subset of the class of materials called two-dimensional hybrid organic-inorganic perovskites. These are thin films consisting of alternating organic and inorganic layers in a highly ordered crystalline structure, as shown in this illustration.

The new metamaterials are incredible things. Researchers never imagined what this kind of thing could do. Above this text is a diagram of the two-layer metamaterial that can transfer energy out from its shell. This kind of material can revolutionize space and aerospace technology. If this material is on the space probe's shell. It can offer great armor against incoming micrometeorites. 

The nano springs between those layers conduct impact energy. And if there is a very cold chamber behind the inner shell, that thing can conduct thermal energy out from the shell. The chamber can filled with liquid nitrogen or helium, and the system can dump the thermal energy into that chamber. 

A similar system can make the hypersonic flight possible in the atmosphere. The idea is that the system conducts thermal energy into the middle of the craft. In some visions, there is a tunnel from the nose of the hypersonic craft to the back of the craft. The airflow travels through the aircraft, and the system can transfer heat from that aircraft shell to that airflow. 

The airflow can travel between those layers, and it can pull thermal energy with it. Another thing is that the next-generation stealth materials are the holed graphene plates. In that material are the pyramid-shaped structures that scatter the incoming radio waves. The plasma that flows in this structure can also pull radio waves in it. And that thing denies the radar echo. 

Theoretically, these kinds of materials and structures can resist the laser or even nuclear weapons. The nuclear explosion releases a very powerful thermal energy burst. And also the pressure impulse is a very powerful thing. If the material can conduct the heat and impact energy out from the shell, into some kind of low-energy tank. It's theoretically possible to create structures that can resist the nuclear explosive. 

The liquid nitrogen tank can offer a place, where the system can conduct thermal energy. Liquid nitrogen can also pull the physical impact energy in itself like water does at room temperature. It's possible. Between those layers is the extremely low-pressure and cold quantum gas. The quantum gas can pull heat energy itself, and the expansion of that gas is not as dangerous as normal pressure gas is.

MIT's tractor beam can make the new types of SASER systems possible

   "This chip-based "tractor-beam," which uses an intensely focused beam of light to capture and manipulate biological particles without damaging the cells, could help biologists study the mechanisms of diseases."(Interesting Engineering, MIT’s Star Wars-inspired ‘tractor beam’ uses light to capture, manipulate cells) MIT's tractor beam can make the new types of SASER systems possible. The tractor beam just hovers the nanoparticle in air or medium, and then the laser or some other electromagnetic system transports oscillation into those particles. The ability to make cells and other particles hover in the system makes it possible to create particles whose energy level or resonance frequencies are accurately calculated things.  That thing makes it possible to create things that transmit wave movement accurately and cleanly. This is one version of the use of a tractor beam. Modern tractor beams are like acoustic tweezers where sound waves lock the object in its cr

The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible.

  "An illustration of NASA’s research plane ER-2 flying over thunderstorms. Credit: University of Bergen / Mount Visual (CC BY 4.0), edited" (ScitechDaily, Surprising Discovery: NASA’s Retrofitted U2 Spy Plane Reveals Tropical Lightning Storms Are Radioactive) The new observations tell that the thunderstorms form gamma-rays. That could make gamma-ray lasers possible. The process has been observed by the NASA (Lockheed) ER-2 research plane, which is a modified U-2 spy plane. The gamma-ray formation in thunderstorms. Where lightning and electric fields release electrons that impact the air molecules and water droplets is an interesting thing. That thing opens the route to solving many mysteries.  "The general physics behind how thunderstorms create high-energy flashes of gamma radiation is not a mystery. As thunderstorms develop, swirling drafts drive water droplets, hail, and ice into a mixture that creates an electric charge much like rubbing a balloon on your shirt. Pos

Chinese innovations and space lasers are interesting combinations.

Above: "Tiangong is China's operational space station located in low Earth orbit. (Image credit: Alejomiranda via Getty Images)" (Scpace.com, China's space station, Tiangong: A complete guide) Chinese are close to making nuclear-powered spacecraft.  Almost every day, we can read about Chinese technical advances. So are, the Chinese more innovative than Western people? Or is there some kind of difference in culture and morale between Western and Chinese societies? The Chinese superiority in hypersonic technology is one of the things that tells something about the Chinese way of making things.  In China, the mission means. And the only thing that means is mission. That means that things like budgets and safety orders are far different from Western standards. If some project serves the Chinese communist party and PLA (People's Liberation Army) that guarantees unlimited resources for those projects. Chinese authorities must not care about the public opinion.  If we th
