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...

Hyperbolic lattices underlie a new form of quantum matter with potential applications to computing and simulation which, date, have been engineered artificially. A corresponding hyperbolic band theory has emerged, extending 2-dimensional Euclidean in natural way higher-genus configuration spaces. Attempts develop the analogue Bloch's theorem revealed an intrinsic role for algebro-geometric modu...

in this work facile sol-gel (pechni) method has been successfully established to synthesize zn4b6o13 nanocrystals which have cubic crystals with lattice parameter: a =7.48 a. the structure and morphology of the obtained material were studied by x-ray diffraction (xrd), infrared spectra (ir), scanning electron microscopy (sem) and photoluminescence analysis. the experimental results show a band ...
