Title: Methods of forming boron nitride

Abstract

A method of forming a boron nitride. The method comprises contacting a metal article with a monomeric boron-nitrogen compound and converting the monomeric boron-nitrogen compound to a boron nitride. The boron nitride is formed on the same or a different metal article. The monomeric boron-nitrogen compound is borazine, cycloborazane, trimethylcycloborazane, polyborazylene, B-vinylborazine, poly(B-vinylborazine), or combinations thereof. The monomeric boron-nitrogen compound is polymerized to form the boron nitride by exposure to a temperature greater than approximately 100.degree. C. The boron nitride is amorphous boron nitride, hexagonal boron nitride, rhombohedral boron nitride, turbostratic boron nitride, wurzite boron nitride, combinations thereof, or boron nitride and carbon. A method of conditioning a ballistic weapon and a metal article coated with the monomeric boron-nitrogen compound are also disclosed.

Method for forming monolayer graphene-boron nitride heterostructures

Patent Sutter, Peter Werner; Sutter, Eli Anguelova

A method for fabricating monolayer graphene-boron nitride heterostructures in a single atomically thin membrane that limits intermixing at boundaries between graphene and h-BN, so as to achieve atomically sharp interfaces between these materials. In one embodiment, the method comprises exposing a ruthenium substrate to ethylene, exposing the ruthenium substrate to oxygen after exposure to ethylene and exposing the ruthenium substrate to borazine after exposure to oxygen.

Method and device to synthesize boron nitride nanotubes and related nanoparticles

Patent Zettl, Alexander K.

Methods and apparatus for producing chemical nanostructures having multiple elements, such as boron and nitride, e.g. boron nitride nanotubes, are disclosed. The method comprises creating a plasma jet, or plume, such as by an arc discharge. The plasma plume is elongated and has a temperature gradient along its length. It extends along its length into a port connector area having ports for introduction of feed materials. The feed materials include the multiple elements, which are introduced separately as fluids or powders at multiple ports along the length of the plasma plume, said ports entering the plasma plume at different temperatures.more » « less

Patent Zettl, Alexander K.; Dunn, Gabriel P.; Gilbert, Stephen M.

This disclosure provides systems, methods, and apparatus related to few-layer and monolayer hexagonal boron nitride having a pore therein. In one aspect, a method comprises providing a sheet of hexagonal boron nitride (h-BN). A defect is created in the sheet of h-BN. The sheet of h-BN is heated to a temperature above about 500° C. The defect in the sheet of h-BN is irradiated with charged particles to enlarge the defect to a hexagonal-shaped pore or a parallelogram-shaped pore in the sheet of h-BN.
