With the highest reported hardness for spinel NRL's nanocrystalline spinel demonstrates that the hardness of transparent ceramics can be increased simply by reducing the grain size to 28 nanometers.
Sintering is a common method used to create large ceramic and metal components from powders.
and reposition nanoparticles very close to each other to help eliminate porosity in the sintered ceramic. NRL researchers then can exploit the increased surface potential of nanoparticles for surface energy-driven densification without coarsening.
when you make a ceramic material nanocrystalline. However in their work the NRL researchers have shown that the fracture resistance does not change suggesting that nanocrystalline ceramics can have an equivalent toughness to microcrystalline ceramics
which is important for high window lifetimes. The Hall-Petch relationship has been used to describe the phenomenon where a material's strength
However prior experimental work had shown a breakdown in this relationship (where hardness starts reducing with decreasing grain size) for certain ceramics at 130 nanometers.

and the Teflon has a low refractive index. When combined, they create a metamaterial, capable of bending light in unusual ways.
and joints they could make ceramics metals and other materials that can recover after being crushed like a sponge.
Ceramics for example are strong but also heavy so they can t be used as structural materials where weight is critical##for example in the bodies of cars.
And when ceramics fail they tend to fail catastrophically shattering like glass. But at the nanoscale the same rules do not apply.
In this size range the structural and mechanical properties of ceramics become less tied to properties such as weight
For ceramics smaller is tougher says Greer who was named one of MIT Technology Review s 35 Innovators Under 35 in 2008 for her work on nanoscale mechanics.
Greer worked with the company to characterize the material and later chose to take on the greater challenge of making ceramics with similar properties.
The polymer lattice is coated then with a ceramic such as alumina. Oxygen plasma etches out the polymer leaving behind a lattice of hollow ceramic tubes.
When the walls are thick the ceramic shatters under pressure as expected. But trusses with thinner walls just 10 nanometers thick buckle
