Boron nitride nanotubes (BNNTs) are functionalized and solubilized in organic solvents such as chloroform, methylene chloride, and tetrahydrofuran by using conjugated poly(p-phenylene ethynylene)s (PPEs) (polymers A and B) and polythiophene (polymer C) via a noncovalent functionalization approach through strong π-π stacking interactions between the conjugated polymers and BNNTs. The functionali...

Multiwalled boron nitride nanotubes (BNNTs) were compressed at room temperature in diamond anvil cells up to 35 GPa, followed by decompression. For the first time, in situ infrared absorption spectroscopy was used to monitor BNNT structural transformations. These BNNTs were found to undergo pressure-induced transformations from a hexagonal to a more closely packed wurtzite structure at 11 GPa, ...

Carbon nanotubes (CNTs) are promising as the drug carriers to cells for various biomedical applications including cancer therapy. Toxicity of CNTs was a debatable issue as previous studies were performed using long and unfunctionalized CNTs, which tend to entangle in the biological systems and lead to various lung lesions and blocking of the airways. More recent in vitro and in vivo studies ind...
