Rolling contact fatigue of silicon nitride. [PDF]

Silicon Nitride has traditionally been used as rolling contact bearing material owing to its superior performance compared to bearing steels. Its successful application as a bearing element has led to the development of Silicon Nitride in other rolling ...

Unidirectional motion of C60-based nanovehicles using hybrid substrates with temperature gradient

Scientific Reports, 2023
With the synthesis of nanocar structures the idea of transporting energy and payloads on the surface became closer to reality. To eliminate the concern of diffusive surface motion of nanocars, in this study, we evaluate the motion of C60 and C60-based ...

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

Improved thermal conductivity and AC dielectric breakdown strength of silicone rubber/BN composites

Composites Part C: Open Access, 2020
The present study demonstrates a synergistic effect with the addition of low loading levels of boron nitride filler in silicone rubber that resulted in significant improvement in both ac breakdown strength and thermal conductivity of silicone rubber ...

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 ...
