“…Therefore, they can be exploited in the biological field after an appropriate noncovalent [45,46] or covalent [47] modification, which can increase their dispersibility in water. BNNTs were used as smart materials [7], drug [47] and gene delivery systems [48], biomaterials [49], sensory systems [50], as well as hydrogen storage [51]. …”

Featured Application: The review is focused on the stabilization of nanotubular materials in solvent media. This aspect is a key starting point for any application of nanotube-based formulations for pharmaceutical and industrial applications.Abstract: Inorganic nanotubes are attracting the interest of many scientists and researchers, due to their excellent application potential in different fields. Among them, halloysite and imogolite, two naturally-occurring aluminosilicate mineral clays, as well as boron nitride nanotubes have gained attention for their proper shapes and features. Above all, it is important to reach highly stable dispersion in water or organic media, in order to exploit the features of this kind of nanoparticles and to expand their applications. This review is focused on the structural and morphological features, performances, and ratios of inorganic nanotubes, considering the main strategies to prepare homogeneous colloidal suspensions in various solvent media as special focus and crucial point for their uses as nanomaterials.

“…BNNTs possess attractive physical and chemical properties; i.e., high chemical stability, high oxidation resistance, excellent mechanical properties and high thermal conductivity, that render them as appropriate candidates to be used as functional composites [4], nanoinsulating covers [5], gas accumulators [6,7], and can be valuable nanodevices working in hazardous and extreme environments. Excellent recent reviews focused on the structure, synthesis and applications of BNNTs are available [8][9][10].…”

Abstract:The adsorption of H 2 O, NH 3 and HCOOH as polar molecules and C 6 H 6 and CH 4 as non-polar ones on a series of zig-zag (6,0) single-walled boron nitride nanotubes (BNNTs) both being defect-free (P_BNNT) and containing defects at the nanotube walls has been studied by means of B3LYP-D2* periodic calculations. We focused on defects derived from monovacancies of B (N-rich_BNNT) and N (B-rich_BNNT) atoms and also on Stone-Wales defects (SW_BNNT). The adsorption of polar molecules with defective BNNTs is generally based on dative interactions and H-bonding, and their adsorption energies strongly depend on the type of BNNT. N-rich_BNNT is the most reactive nanotube towards adsorption of polar molecules, as in all cases deprotonation of the polar molecules is spontaneously given upon adsorption. The strength in the adsorption energies is followed by B-rich_BNNT, SW_BNNT and P_BNNT. Adsorption of non-polar molecules is mainly dictated by dispersion interactions, and, accordingly, the adsorption energies are almost constant for a given molecule irrespective of the type of nanotube.

“…The high surface/volume ratio of nanomaterials has significant implications with respect to energy storage. Functionalized single walled carbon nanotubes (SWCNTs) are one of the most promising materials, can adsorb and release a large quantity of hydrogen easily, reliably, safely and efficiently [1]. We have done experimental investigation of hydrogen storage in functionalized SWCNTs.…”

We have done the experimental investigation of hydrogen storage in functionalized single-walled carbon nanotubes (SWCNTs). The SWCNTs having the average diameter of 22 nm are deposited on alumina substrates by drop casting method. The functionalization of SWCNTs with BH 3 using LiBH 4 as the precursor, over the surface of SWCNTs is done by the same chemical method. Further, the functionalized samples are hydrogenated in the hydrogenation chamber. The samples are characterized through FTIR, XPS and CHNS studies. A hydrogen storage capacity of 0.87 wt % at 100º C is observed.
