Nanaomaterials

The arrangement of atoms in nanosolids is not only different from the long-range ordered crystal, but also different from the long-range disordered and short-range ordered "gas" solid structure. It is a metastable intermediate state material between the solid and the molecule. Therefore, some researchers call nanomaterials as "third state crystal materials" besides crystalline and amorphous. Because of the special structure of nanomaterials, the nanomaterials has four major effects, namely, small-scale effect, quantum effect (including macro quantum tunneling effect), surface effect and interface effect, so they have the physical and chemical properties that traditional materials do not have, and show unique optical, electrical, magnetic, catalytic, chemical properties and superconducting properties Therefore, nanomaterials have important application value in national defense, electronics, chemical industry, metallurgy, light industry, aviation, ceramics, nuclear technology, catalyst, medicine and other fields.
