The difference between the nanostructures and regular structures is that the nanostructures and nanomaterials are created atom by atom. If we think about the titanium bricks that the next text handles the nano-version is similar. Only the size of the objects that create the structure is different. The nano-size structures are like atom chains. They can raise the strength of the material to a very high level. 

The nanotubes can involve other materials than carbon. The ion systems can make it possible to put some other atoms and molecules between graphene nanotubes. Those other atoms are making that structure stronger. Because they allow carbon atoms can load energy into those pockets. 

This is the reason why carbon gives strength to steel. The Damascus steel involves fullerene, where iron can dump energy when it hits something. The fullerene nanotubes can conduct impact energy out of steel. And the fullerene can also be put in titanium material, where titanium replaces steel. That thing allows to creation of the Damascus titanium alloy. 

Researchers created a very hard titanium structure that is also very light. The idea is that this titanium network or 3D structure using nano-printers gives strength and lightness. The 3D structure has a lot of space and is also lightweight. Because there is space between those titanium structures. That makes it able to deliver impact energy to that space. The nanotechnical titanium bricks can be small in size. And that structure denies the damage to growth. 

This kind of lightweight structure can used in ground and aerial vehicles and in things like submarines. It's nanoversion can used in things. Like firerm strutures. The best solution would be the thin composite armor there is one layer is about one or two atom layers. Then that titanium structure will be below it.

The network structure can used in submarines there that structure can also deny echoes. And the modern lightweight titanium composite armor could look like the thing that is seen in the second image from the top. There could be titanium or some other very strong material outside. 

That material can be graphene, polymer, and titanium composite, where those layers are like in hamburgers.  And then the titanium structure is in the middle of those plates. Titanium structure can replaced using an "altermagnetic" structure.

If that outside plate lets sonar impulses travel through it, that system can also deny the acoustic echo. When radar impulses hit that structure that thing can also cause the situation. Their radio impulses start to jump between those metal wires. And that makes material invisible to radar. In that system, electricity is transported from the upper layer to the lower layer, and the system should only deny the echo. 

The idea is that the system can deny echo simply by transporting electricity from the upper layer to the lower layer. The new state of magnetism called "Altermagnetism" is one of the things that can make things like antimagnetic structures possible. The structure in those titanium bricks can replaced using an altermagnetic structure. In that structure is no outside magnetic field. And that thing makes it possible to create antimagnetic structures for submarines and aircraft. The "Altermagntism" denies the use of magnetic sensors to detect submarines.
