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 ...

Porous Ultralow-κ sp<sup>2</sup>-Bonded Boron Nitride Thin Films as Copper Diffusion Barriers. [PDF]
Adv Sci (Weinh)Porous sp2‐bonded boron nitride (p‐BN) thin films with an ultralow dielectric constant (κ = 1.77) are directly grown on Si substrates via RF magnetron sputtering. The films feature uniform nanopores (1.85 nm), high mechanical stability, hydrophobicity, and excellent Cu diffusion barrier performance even at 3 nm thickness, offering a promising solution ...

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.
