Abstract
Based on the DFT in a Wb97xd/6-311+G* level of theory, the interaction of thymine derivatives with Be12O12 and Ca12O12 nanocages was investigated. It was found that adsorption energies of thymine molecules on the Be12/Ca12-O12 surface was around -43.16, -60.06 and -29.62, -50.71, -45.95, -30.27 kcal/mol, for thymine (TH1), 1-amino thymine (TH2) and thymine glycol (TH3), respectively and this result supported the drug's adsorption. Additionally, according to the FMOs and MEP studies, a charge transfer from TH's to nanocages. Additionally, both molecular orbitals demonstrate that the LUMO and HOMO are primarily found on the BeO's surface.

Abstract
In this study, the adsorption of gases (CH4, CO, H2, NH3, and NO) onto Al12Si12 nanocages was theoretically investigated using density functional theory. For each type of gas molecule, two different adsorption sites above the Al and Si atoms on the cluster surface were explored. We performed geometry optimization on both the pure nanocage and nanocages after gas adsorption and calculated their adsorption energies and electronic properties. The geometric structure of the complexes changed slightly following gas adsorption. We show that these adsorption processes were physical ones and observed that NO adsorbed onto Al12Si12 had the strongest adsorption stability. The E g (energy band gap) value of the Al12Si12 nanocage was 1.38 eV, indicating that it possesses semiconductor properties. The E g values of the complexes formed after gas adsorption were all lower than that of the pure nanocage, with the NH3-Si complex showing the greatest decrease in E g. Additionally, the highest occupied molecular orbital and the lowest unoccupied molecular orbital were analyzed according to Mulliken charge transfer theory. Interaction with various gases was found to remarkably decrease the E g of the pure nanocage. The electronic properties of the nanocage were strongly affected by interaction with various gases. The E g value of the complexes decreased due to the electron transfer between the gas molecule and the nanocage. The density of states of the gas adsorption complexes were also analyzed, and the results showed that the E g of the complexes decreased due to changes in the 3p orbital of the Si atom. This study theoretically devised novel multifunctional nanostructures through the adsorption of various gases onto pure nanocages, and the findings indicate the promise of these structures for use in electronic devices.

Abstract
The electronic sensitivity and adsorption behavior for mercaptan natural gas of a Ca12O12 nanocluster were studied via ab initio computations. To be more specific, to fully grasp the influence of mercaptan molecules on the chemical and electronic features of Ca12O12 nanocluster, some parameters, namely, charge transfer of natural bond orbital, molecular electrostatic potential, binding energies, and frontier molecular orbitals, are computed. The interaction between CH4S molecule and calcium atoms of Ca12O12 nanocluster through the sulfur head is strong. This strong interaction leads to a considerable transfer of charge from CH4S to the nanocluster. After mercaptan adsorption, the existing energy gap between two levels, the highest occupied molecular orbital (HOMO) and the lowest unoccupied molecular orbital (LUMO) of the nanostructure, dropped by 2.21 eV, illustrating that the dissociation process has extensively increased the electrical conductance of nanostructure. This electrical signal can help to detect CH4S molecules. Moreover, it could be concluded that Ca12O12 nanocluster has a short recovery time. In addition, solvent considerably influences the geometry factors and electronic features of CH4S/Ca12O12 complexes, and the interactions between species are significantly weaker in the aqueous medium compared with those in the vacuum.

Abstract
Density functional theory (DFT) calculations were used to study the effect of scandium doping on the structural, energetic, electronic, linear and nonlinear optical (NLO) properties of Be12O12, Mg12O12 and Ca12O12 nanoclusters. Scandium (Sc) doping on nanoclusters leads to narrowing of their E g, which enhances their conductance greatly. Also, the polarizability (α) and first hyperpolarizability (β0) of nanoclusters were dramatically increased as Be, Mg or Ca atoms are substituted with a Sc atom. Among all clusters, α and β0 values for Sc-doped Ca12O12 were the largest. Consequently, the effect of the doping atom, as well as of cluster size, on electronic and optical properties was explored. Time dependent (TD)-DFT calculations were also carried out to confirm the β0 values; the results show that the higher value of first hyperpolarizability belongs to Sc-doped Ca12O12, which has the smallest transition energy (ΔEgn). The results obtained show that these clusters can be candidates for using in electronic devices and NLO materials in industry.

Abstract
Single-walled aluminum nitride nanotubes (AlNNTs) are introduced as an electronic sensor for detection of sulfur dioxide (SO₂) molecules based on density functional theory calculations. The proposed sensor benefits from several advantages including high sensitivity: HOMO-LUMO energy gap of the AlNNT is appreciably sensitive toward the presence of SO₂ so that it decreases from 4.11 eV in the pristine tube to 1.01 eV in the SO₂-adsorbed form, pristine application: this nanotube can detect the SO₂ molecule in its pristine type without manipulating its structure through doping, chemical functionalization, making defect, etc., short recovery time: the adsorption energy of SO₂ molecule is not so large to hinder the recovery of AlNNTs and therefore the sensor will possess short recovery times, and good selectivity: the tube can selectively detect the SO₂ molecule in the presence of several molecules such as H₂O, CO, NH₃, HCOH, CO₂, N₂, and H₂.
