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).

Encapsulated thermoacoustic projector based on freestanding carbon nanotube film [PDF]
, 2017 A suspended nanotube film (or films) producing sound by means of the thermoacoustic (TA) effect is encapsulated between two plates, at least one of which vibrates, to enhance sound generation efficiency and protect the film.

Excitons in Boron Nitride Nanotubes: Dimensionality Effects [PDF]
Physical Review Letters, 2006 We show that the optical absorption spectra of boron nitride (BN) nanotubes are dominated by strongly bound excitons. Our first-principles calculations indicate that the binding energy for the first and dominant excitonic peak depends sensitively on the dimensionality of the system, varying from 0.7 eV in bulk hexagonal BN via 2.1 eV in the single ...

Building blocks for one-dimensional van der Waals heterostructures
National Science Open, 2022 We recently demonstrated experimentally the synthesis of one-dimensional (1D) van der Waals (vdW) heterostructure, where single-crystal hexagonal boron nitride or molybdenum disulfide nanotubes seamlessly wrapped a single-walled carbon nanotube and ...

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.
