in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
Applying of intensive cultivation especially in marginal and sensitive regions, after conversion of rangelands to cropland farms, commonly causes reduction in soil quality, and thus an increase in soil degradation, erosion and runoff. This study was conducted to evaluate the land use change effects on some soil physical and chemical properties such as mean weight diameter (MWD), soil organic ...
In this study, Nitrogen doped TiO2 photocatalysts were prepared by the sol gel method and physicochemical properties were characterized by X-ray diffraction (XRD), and scanning electron microscopy (SEM), photoluminescence, and energy dispersive X-ray spectroscopy (DRS) techniques. The XRD data indicated that the nanoparticles had the same crystals structures as the pure TiO2</su...
psychometric properties of automatic thoughts questionnaire and investigation of the relationship between automatic thoughts with cognitive emotion regulation and self regulated learning
This study determined the effect of thiourethane-functionalized fillers (TU) on antimicrobial properties, cytotoxicity, degree conversion (DC), water sorption (Wsp) and solubility (Wsl) experimental composites. TU-modified were added at different ratios in composites: 0 (Control-TU0), 25% (TU25), 50% (TU50), 75% (TU75) 100wt% (TU100). The properties detected through exhaustion test counting Str...
