    摘要: Provided are methods of converting carbon dioxide to carbon nitrides. In a first reaction, carbon dioxide may be reacted with metal nitrides, such as Li3N, to form carbon nitrides in a fast and exothermic reaction. Also provided are methods of using product metal cyanamides from the first reaction to subsequently generate additional carbon nitrides.

    摘要: A field emission electron gun has a field emission cathode composed of a carbon fiber and a conductive base for supporting the carbon fiber, an extractor for causing the field emission of electrons, and an accelerator for accelerating the electrons. The carbon fiber contains at least one of trivalent and pentavalent elements. In particular, the trivalent and pentavalent elements are boron and/or nitrogen. The content of at least one of boron and nitrogen in the carbon fiber is 0.1% to 5% at an atomic weight ratio of the contained element to carbon. The diameter of the carbon fiber is 20 nm to 200 nm. Such an electron gun can have a high-brightness electron beam with a narrow energy width. The field emission electron gun is applied to various electron beam apparatus.

    摘要: A nitride material comprises C.sub.2 N. A method of forming a covalent carbon material includes forming an atomic nitrogen source, forming an elemental reagent source and combining the atomic nitrogen, elemental reagent to form the covalent carbon material and annealing the covalent carbon material. The elemental reagent is reactive with the atomic nitrogen of the atomic nitrogen source to form the covalent carbon material. Annealing the covalent carbon material produces the C.sub.2 N. In one embodiment, essentially all carbon nitride chemical bonds are single or double bonds.
