“…The structural, electronic, magnetic, and reactivity properties of GaPNTs in the armchair and zigzag chirality have been investigated by computational chemistry. Results indicate varied and interesting applications such as drug delivery, particularly for 5-fluorouracil, hydrogen storage, as well as in the fabrication of spintronic and nanoelectronic devices. − AlPNTs have been studied and characterized computationally for the first time by Lisenkov et al The use of these NTs as hydrazine sensors for biomedical applications and as sensors of toxic gases such as acrolein and hydrogen sulfide has been investigated. − On the other hand, the inclusion of transition metals (Co, Ni, Mn) in the structure of AlPNTs allows modulating their electronic and magnetic properties . Another example of NTs is that concerned with the InPNTs.…”

The structural, vibrational, and electronic properties of new inorganic X-phosphide nanotubes (ch-XPNT), with X = Al, Ga, or In and chirality of (5,5), are investigated. These new NTs display cap-hole ends, with the cap-hole features induced by the nonpassivated ends. Studies are based on density functional theory (DFT) using the M06-2X, PBE, and B3LYP functionals together with the LanL2DZ basis set. All nanostructures have been relaxed by minimizing the total energy, assuming a nonmagnetic nature and a total neutral charge. Note that the cap-hole NTs are terminated by a 10-atom ring, which in turn favors the geometrical ordering and yields stable structures. The (5,5) ch-XPNT are highly electrophilic and nonpolar, in addition to having high solvation energy values. Let us remark that solvation energies are produced by the intermolecular forces that involve the induced dipoles. Structural and vibrational results show that the X−P bonds are single bonds. Finally, results suggest that the inorganic nanotubes are structurally stable with semiconductor features, which means that their functionalization may yield interesting future applications.
