Boron nitride (BN) is a binary chemical compound, consisting of equal nuers of boron and nitrogen atoms. The empirical formula is therefore BN. Boron nitride is isoelectronic to the elemental forms of carbon and isomorphism occurs between the two species. That is boron nitride possess three polymorphic forms; one analogous to diamond, one analogous to graphite and ones analogous to the

Moissanite (/ˈmɔɪsənaɪt/)[4] is naturally occurring silicon carbide and its various crystalline polymorphs. It has the chemical formula SiC and is a rare mineral, discovered by the French chemist Henri Moissan in 1893. Silicon carbide is useful for commercial and industrial appliions due to its hardness, optical properties and thermal
Rice University engineers have discovered that pillared graphene could transfer heat better because the theoretical material had a few asymmetric junctions that caused wrinkles. Rice materials scientist Rouzbeh Shahsavari and alumnus Navid Sakhavand built atom
