Simple Laser-Induced Hexagonal Boron Nitride Nanospheres for Enhanced Tribological Performance

Lubricants, 2023
Hexagonal boron nitride, as a layered material with a graphite-like structure, exhibits good mechanical, lubricating and oxidation resistance properties, and is thus expected to become one of the top choices for green lubricating oil additives.

Mechanical properties, thermal conductivity, and modeling of boron nitride-based polymer composites: A review

eXPRESS Polymer Letters, 2021
In the past, polymer materials have been used in electronic devices; however, the major drawback with polymers is their low thermal conductivity, i.e., 0.1–0.5 W/(m・K). Hence, researchers came up with the idea of incorporating conductive fillers into the

Raman Spectroscopy Of Boron Nitride Nanotubes And Boron Nitride — Carbon Composites [PDF]

AIP Conference Proceedings, 2005
Boron nitride nanotubes (BN-NT) are topological analoges to single wall carbon nanotubes (SWCNT). We analysed and refined the filling process for SWCNTs and applied it to the BN-NTs. BN-NTs were first annealed in air to open the ends and to remove BN particles. A filling procedure with C60 fullerene via vapour phase was applied.

Stark Effect of Blue Quantum Emitters in Hexagonal Boron Nitride [PDF]

, 2023
Inhomogeneous broadening is a major limitation for the application of quantum emitters in hexagonal boron nitride to integrated quantum photonics. Here we demonstrate that so-called blue emitters with an emission wavelength of 436 nm are less sensitive ...

Effect of electric field on the band structure of graphene/boron nitride and boron nitride/boron nitride bilayers [PDF]

Applied Physics Letters, 2012
Effect of electric field on the band structures of graphene/boron nitride (BN) and BN/BN bilayers is investigated within the framework of density functional theory. The calculated bandgap of the graphene/BN bilayer increases, although by small amount, with applied electric field.
