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...

jimsonweed (datura stramonium l.) is an important weed in bean fields in iran. in order to investigate the effect of density and relative time of emergence of jimsonweed on yield and yield components of chitti bean, a field study based on factorial experiment was conducted at farm bean research national station in khomein in 2006. treatments were chosen to provide four different weed densities ...

in order to study on effect of plant density and nitrogen on yield and yield components of visia faba (faba bean), the experimental design was implemented by randomized complete block with three replications at 2010- 2011 in lahijan. the experimental factors were three plant density (25×25 cm, 35×35 cm and 45×45 cm) and four nitrogen fertilizer (0, 20, 40, 60 kg ha-1). in this experiment, featu...

In this research, the interaction of pyrimidine molecule with pristine B12N12 nanocluster is studied in different phases to understand the effect of environment on the electronic properties of the designated adsorption complexes. To this end, the pyrimidine adsorption over B12N12 in the gas phase and water medium is investigated using density functional theory (DFT) at the B97D/6-31+G(d,p) leve...

Flash sintering has been investigated as a modern sintering method through examining the effect of processing parameters such as current density, temperature, and contact paste on the flash sintered 8YSZ characteristic. 95% of theoretical density was achieved at 800°С in 30sec with a field intensity of 100V.cm-1 and a current density of 160mA.mm-2. Such relative density in conventional sinterin...
