Composites

Permaglass: a transparent membrane composed of layers of silica aerogel and graphene sheets. Once it was commercialized, regular glass became obsolete due to its friability and low thermal insulation. Although permaglass was slightly less transparent than regular glass it had high thermal insulation and its durability was in the order of millenia.

Fibreconcrete: a compound made of regular concrete reinforced by graphene fibres. Graphene dramatically increases the tensional resistance of the concrete, rendering it immune to cracking and rupturing caused by traction and compression forces as well as projectile impact.

Impermium: alloy fused with graphene fibers which render it impervious to erosion or stain. The standard concentration of graphene in fiberconcrete was of 5%. For impermium it was 33%. Thanks to the extraordinary resilience of graphene (about 200 times stronger than steel), any higher concentration would create the same effect, rendering it a needless excess.

Eternium: high temperature superconductor. Through electric induction eternium was able to generate a stable magnetic field strong enough to withstand any force, depending on the size of the surface and the weight of the body, and its levitating capacity was calculated using the formula F = (Le.l2)/W where Le is the levitation constant of a conductor (for eternium the value is 0.909, for regular iron the value is aprox. 0.003).
