Nanomeetrite

Nanomeetrite is a hypothetical nanomaterial described in speculative nanoscience literature as a nanoscale crystalline phase that forms as discrete nanocrystals typically between 1 and 50 nanometers in size. It is not an established mineral or compound, and no peer-reviewed synthesis has been confirmed.

Proposed formulations for nanomeetrite are generic binary systems such as oxide, sulfide, or carbide chemistries, with a simplified stoichiometry MxOy. The lattice is described as highly ordered at the nanoscale, with motifs that could resemble rock-salt, spinel, or perovskite-type arrangements in smaller domains; surface reconstructions are expected to be prominent.

In theoretical discussions, nanomeetrite nanocrystals are envisioned to form via colloidal synthesis, solvothermal routes, or physical vapor deposition, leading to discrete crystals with high surface area. However, no reproducible experimental protocol has been reported, and characterization remains speculative if any specimens exist.

Predicted properties include size-dependent electronic and optical behavior due to quantum confinement, high surface reactivity, and tunable band gaps in the visible to near-infrared range. Potential applications cited in speculation include catalysis, energy storage, and nanoelectronic or photonic devices, should stable realizations be achieved.

The name nanomeetrite combines nanoscale dimensions with the idea of meeting or aggregation of lattice planes, though there is no established etymology or validated specimen. As such, nanomeetrite remains a theoretical construct within discussions of nanoscale crystallography and materials design.
