Boron nitride nanotubes for gene silencing
Biochimica et Biophysica Acta (BBA) - General Subjects, 2017 Non-viral gene delivery is increasingly investigated as an alternative to viral vectors due to low toxicity and immunogenicity, easy preparation, tissue specificity, and ability to transfer larger sizes of genes.In this study, boron nitride nanotubes (BNNTs) are functionalized with oligonucleotides (oligo-BNNTs).

Computational study of boron nitride nanotube synthesis: how catalyst morphology stabilizes the boron nitride bond [PDF]
, 2009 In an attempt to understand why catalytic methods for the growth of boron nitride nanotubes work much worse than for their carbon counterparts, we use first-principles calculations to study the energetics of elemental reactions forming N2, B2 and BN ...

Are hemispherical caps of boron-nitride nanotubes possible?
, 2004 We report all-electron, density-functional calculations with large Gaussian polarization basis set of the recently synthesized octahedral B24N24 cage that is perfectly round by symmetry, and boron-nitride (BN) clusters that its existence might suggest ...

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.

Iron oxide doped boron nitride nanotubes: structural and magnetic properties
, 2010 A first-principles formalism is employed to investigate the interaction of iron oxide (FeO) with a boron nitride (BN) nanotube. The stable structure of the FeO-nanotube has Fe atoms binding N atoms, with bond length of roughly $\sim$2.1 \AA, and binding ...
