The 3D nanostructure makes it possible to create strong and lightweight materials.

Nanotechnology and nanostructures are miniaturized versions of structures and machines we see every day. The nanostructure makes the material stronger and lighter. One of the examples of nanostructures is the steel plate that is full of small boxes. Steel plate is a strong material and the boxes inside it are making it lighter.

But researchers can make those boxes stronger by using a 3D nanopillar structure that purpose is to stiffen those boxes. This is one of the versions of the nano-steel. That structure makes it strong but there is more space than in regular steel. And that makes it lighter.

One of the interesting possibilities is the metallic aerogel. Aerogel is one of the lightest materials in the world. And if the researchers can copy its structure to metals that make it a powerful tool everywhere there is a need for lightweight structures.

Image 4:) Diamond unit cell, showing the tetrahedral structure. (Wikipedia, Diamond) There is possibility that nanotechnology copies this structure to another atoms. And that makes possible to create new fundamental materials.

Nanotechnology makes it possible to put iron or some other metal atoms into the form that is found in diamonds. Metallic diamonds are one of the dreams of material researchers.

One of the possibilities to make structures stronger is to put graphite between metal layers. In that case, alpha graphite unit cells will be put between metal layers side by side. They should form a thin graphite layer between those metal layers. And that graphite should support those structures.

But the most powerful nanomaterial is graphene. The 2D graphite can use to cover layers. Graphene is one of the strongest materials in the world. There is a possible position of nano springs created by using DNA between two graphene layers. Those springs will make the graphene layers stronger than ever. When something hits graphene the impact will transmit to the nano springs. And that thing makes two-layer graphene a very strong material.

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology. Could a hypothetical Planet X tunnel all radiation? The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory. And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact. In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
