This study focused on the potential of aluminum nitride
(Al12N12) and aluminum phosphide (Al12P12) nanomaterials as anode electrodes of lithium-ion
(Li-ion),
sodium-ion (Na-ion), and potassium-ion (K-ion) batteries as investigated
via density functional theory (DFT) calculations at PBE0-D3, M062X-D3,
and DSDPBEP86 as the reference method. The results show that the Li-ion
battery has a higher cell voltage with a binding energy of −1.210
eV and higher reduction potential of −6.791 kcal/mol compared
to the sodium and potassium ion batteries with binding energies of
−0.749 and −0.935 eV and reduction potentials of −6.414
and −6.513 kcal/mol, respectively, using Al12N12 material. However, in Al12P12, increases
in the binding energy and reduction potential were observed in the
K-ion battery with values −1.485 eV and −7.535 kcal/mol
higher than the Li and Na ion batteries with binding energy and reduction
potential −1.483, −1.311 eV and −7.071, −7.184
eV, respectively. Finally, Al12N12 and Al12P12 were both proposed as novel anode electrodes
in Li-ion and K-ion batteries with the highest performances.
This research is focused on the sensor properties of pure and X-decorated ([Formula: see text], N, P and S) magnesium oxide (Mg[Formula: see text]O[Formula: see text]) nanocages for melamine (C3H6N6) molecule detection using density functional theory (DFT) electronic structure approach. Comparative adsorption study was carried out on four distinct computational models of hybrid functionals: [Formula: see text]B97XD, PBE0-D3BJ, M062X-D3BJ and DSDPBEP86 with the double-hybrid (DSDPBEP86), being the superior model at the fifth rung of the Jacobi’s ladder, was used as the reference. The atoms-in-molecule (AIM), alongside with the non-covalent interactions (NCIs) as visual extension had been utilized in the study of weak interactions and to affirm the degree of interactions between the clusters and the toxin. In all cases, this study suggests that the adsorption phenomena are best described as chemisorption due to the negative adsorption enthalpy observed. The mean absolute deviation (MAD) and root mean square deviation (RMSD) statistical approaches suggest the behavior of the possible adsorptions to be ranked as follows: PBE0-D3BJ (first rank), [Formula: see text]B97XD (second rank) and finally, M062X-D3BJ (third rank) with ([Formula: see text], 0.7870 and 0.8402) and ([Formula: see text], 0.8946 and 0.9560), respectively. These results are consistent with those of the topological and the sensing parameters, hence, arriving at a conclusive scientific report that Mg[Formula: see text]O[Formula: see text] and Mg[Formula: see text]PO[Formula: see text] surfaces exhibit relatively better sensing performances for the trapping of melamine (MB).
