despite its numerous potential applications, two-dimensional monolayer graphyne, a novel form of carbon allotropes with sp and sp2 carbon atoms, has received little attention so far, perhaps as a result of its unknown properties. especially, determination of the exact values of its elastic properties can pave the way for future studies on this nanostructure. hence, this article describes a dens...

objective(s): adsorption of immucillin-a (bcx4430) molecule on the pristine and n-doped tio2 anatase nanoparticles were studied using the density functional theory (dft) calculations. the adsorption energy analysis indicated that tio2+immucillin-a complexes including oc-substituted tio2 have higher adsorption energy than the complexes with ot substituted tio2, thus providing more stable configu...

stabilizations and atomic level quadrupole coupling constant (cq) properties have been investigated for graphene–like monolayers (g–monolayers) of boron nitride (bn), boron phosphide (bp), aluminum nitride (aln), and aluminum phosphide (alp) structures. to this aim, density functional theory (dft) calculations have been performed to optimize the model structures and also to evaluate the cq para...

we have performed density functional theory investigations on the adsorption properties of ammonia molecule on the undoped and n-doped tio2 anatase nanoparticles. we have geometrically optimized the constructed undoped and n-doped nanoparticles in order to fully understand the adsorption behaviors of ammonia molecule. for tio2 anatase nanoparticles, the binding site is preferentially located on...

to explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. the electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. the graphene with the most stable configuration defect named as sw defect is considered. the hig...

density functional theory ,(dft) calculations have been performed to investigate the properties ofcarbon decorated (c-decorated) models of boron nitride (bn) nanocones. to this aim, the apex andtip of nanocone have been substituted by the carbon atoms to represent the c-decorated models. theresults indicated that dipole moments and energy gaps could reveal the effects of c-decorations onthe pro...

electrode potential of 2-(2,3-dihydroxy phenyl)-1,3-dithiane (dpd) was investigated by means of cyclic voltammetry (cv) at various potential scan rates. the calculated value was compared with the experimental value obtained by cyclic voltammetry (cv). all experiments were done in aqueous phosphate buffer solutions at different phs. the experimental redox potential of dpd was obtained to be 0.75...

ethno-musicology is an academic field encompassing various approaches to the study of music that emphasize its cultural, social, material, cognitive, biological, and other dimensions or contexts instead of its isolated ‘sound’ component or any particular repertoire. the term ‘ethno-musicology’ became common in1950, although the emergence of the field can be traced back to the late nineteenth ce...

dft calculations were applied to evaluate the electronic and magnetic properties of zigzag bc2nnanotubes based on the 13c, 15n, and 11b nmr parameters and natural charge analysis. weconsidered three types of zigzag nanotubes, zz-1, zz-2, and zz-3 (n, 0) with n = 8, 12, and 14. theobtained results indicated the divisions of the electrostatic environments around c nuclei into a fewlayers, consist...

in this research, structural and electronic properties of zncdn-1ten clusters (n=1-10) have been studied by formalism of density functional theory and using the projector augmented wave within local density approximation. the structural properties (such as bond length/angle and coordination number), electronic and optical properties (such as binding energy, kohn-sham spectrum and partial charge...
