boron nitride

American  

noun

Chemistry.

1. a white powder, BN, formed by heating boron in nitrogen. In its ordinary form, it has a structure of stacked layers of hexagonal rings, very similar to that of graphite, and is used as a refractory electrical insulator.

Example Sentences

The researchers solved this by designing a plasmonic-excitonic heterostructure made with nanometer-thin boron nitride layers, which proved essential for revealing the newly identified dark excitons.

From Science Daily

These values surpass those of commonly used materials such as silicon dioxide and hexagonal boron nitride.

From Science Daily

Researchers want to use inorganic 2D materials such as boron nitride or MXenes to build batteries that are more powerful, develop electronic components or improve other materials.

From Science Daily

They can be created by combining metals and ligands, ranging from those with metallic properties such as graphene and semiconducting properties such as transition metal dichalcogenides to the ones possessing insulating properties such as boron nitride.

From Science Daily

Rice researchers focused on graphene, which is made up of carbon atoms, and hexagonal boron nitride, a material with a similar structure to graphene but composed of boron and nitrogen atoms.
