Abstract C 8 H 4 INS 3 , monoclinic, P 2 1 / c (no. 14), a = 11.8060(19) Å, b 7.8961(14) 11.972(2) β 110.981 ( 2 ) ° $110.981(2){}^{\circ}$ V 1042.1(3) Å Z 4, R gt ( F ) 0.0279, wR ref 0.0739, T 296(2) K.
Thermal retention of ferroelectric hafnium zirconium oxide (HZO) is a critical reliability concern impacting its use in applications such as field-effect transistors, random-access memory, and tunnel junctions. depolarization thermal imprint are explored for 10 nm thick Hf0.5Zr0.5O2 films. The HZO films were fabricated through atomic layer deposition with two different oxidizing conditions, H2O...
In this study, the dissociative adsorption of NaNO2, NaNO3, HNO2, HNO3 and H2SO4 over (1 1 0) surface of γ-alumina non-spinel model were investigated through the dispersion corrected density functional theory (DFT-D) at PBE-D/DNP level of calculation. It was found that all of the species are dissociated to their ionic forms after...
The crystal structure of nequinate has been solved and refined using synchrotron X-ray powder diffraction data optimized density functional techniques. Nequinate crystallizes in the space group P 2 1 / c (#14) with a = 18.35662(20), b 11.68784(6), 9.06122(4) Å, β 99.3314(5)°, V 1918.352(13) Å 3 , Z 4. is dominated by stacking approximately planar molecules. N–H⋯O hydrogen bonds link adjacent mo...
New bionanocomposite proton exchange membranes were prepared from sulfonated polybenzimidazole (s-PBI) and various amounts of sulfonated ZnO/cellulose nanohybrids (ZnO/cellulose-SO3H). The use of ZnO/cellulose-SO3H compensates for the decrease in ion exchange capacity of membranes observed when non-sulfonated nano-fillers are utilized. The strong –SO3H/–SO<su...
نفتالین در اثر سوختن مواد آلی از قبیل سوختهای فسیلی و چوب، صنایع و انتشار از اگزوز خودروها وارد محیط زیست میشود. نفتالین در ساخت پلاستیک، رزین، سوخت و رنگها استفاده میشود. این پژوهش با هدف ارزیابی عملکرد فرایند UV/TiO2/H2O2در تجزیه نفتالین از محلول آبی انجام شد. تجزیه فوتوکاتالیستی نفتالین، توسط تابش نور <s...
