The electronic and structural properties of pristine and carbon doped (C-doped) boron nitride nano-ribbons(BNNRs) have been studied employing density functional theory (DFT) calculations. Total energies, gapenergies, dipole moments, and quadrupole coupling constants (qcc) have been calculated in the optimizedstructures of the investigated BNNRs. The results indicated that the stability and gap ...

Theaim of this paper is to report on generation-oriented research conducted by the Systemic Meaning Modelling Group based at Macquarie University, Sydney, and involving researchers-at other institutions in Australia, Germany and Japan. We will describe the core generation system Multex, which is a system for generating multilingual and multimodal presentations, based on the principles of system...

In this manuscript, density functional theory was used to explore structural, vibrational and optical properties of the (Sc2O3)n (n=1-5) cluster systems using DFT/B3LYP/LanL2DZ level of computation. Different stable isomers were obtained and numerous chemical parameters such as HOMO-LUMO gap, ionization potential and electron affinity were calculated successfully. Stability of the clusters was ...

The fixed point alternative methods are implemented to giveHyers-Ulam  stability for  the quintic functional equation $ f(x+3y)- 5f(x+2y) + 10 f(x+y)- 10f(x)+ 5f(x-y) - f(x-2y) = 120f(y)$ and thesextic functional equation $f(x+3y) - 6f(x+2y) + 15 f(x+y)- 20f(x)+15f(x-y) - 6f(x-2y)+f(x-3y) = 720f(y)$   in the setting ofintuitionistic fuzzy normed spaces (IFN-spaces).  This methodintroduces a met...

in this study, the geometries of the [sininhn]q and [sicunhn]q clusters, (n = 4,5,6 and q = 0,+1,-1) complexes have been optimized to form complexes with four, five and six planar and nonplanarsubstituents, with negative, neutral or positive atomic charge, using density functionaltheory (dft) at b3lyp/6-311+g (3df, p) computational level and then their thermodynamicstability were investigated b...

the structure and the electronic properties of single-walled zigzag bn and b3c2n3 nanotubes (n, 0; n=4–10) were investigated using first-principles calculations based on a density functional theory. a plane–wave basis set with periodic boundary conditions in conjunction with vanderbilt ultrasoft pseudo-potential was employed. the energy gap of zb3c2n3nts was calculated and compared with the cor...

adsorption of no2 molecule on pristine and n-doped tio2 anatase nanoparticles have been studied using the density functional theory (dft) technique. the structural properties (such as bond lengths and bond angles) and the electronic properties (such as density of states, band structures and atomic partial charges) have been computed for considered nanoparticles. the results show that, the adsor...

in present study, the density functional theory (dft-b3lyp) method with svp basis set was used for optimizing and studying the electronic structural properties of cis and trans isomers of bis-(5-nitro-2h-tetrazolato-n2) tetraammine cobalt (iii) perchlorate (bncp) as powerful explosives at 298.15 k temperature and 1 atmosphere pressure. and also, natural bond orbital (nbo) population analysis an...

in this study, catalyst of rutile titanium dioxide nanoparticles (rtio2-np) has been investigated for the removal and reduction of unburned hydrocarbons as benzopyran. to evaluate and calculate the thermodynamic properties of this aim, pollutants are closed to the nanoparticles and converted them into other products and the carbon dioxide molecules are simulated in the 12th steps. the geometric...
