Functional features of Ni-W composite materials combined with successful performance enabled a breakthrough in their broad application. To disclose the formation pathway at extreme conditions combustion synthesis NiO-WO3-Mg-C and NiWO4-Mg-C systems for optimization procedure, process was modeled under programmed linear heating by thermal analysis methods. The reduction kinetics tungsten nickel ...
In this study, WO3:Ni (0 at.%, 10 20 and 30 at.%) WO3:Co20 at.%: Ni (0%, 5%, 10%, 20%, 30%) thin films were deposited on glass substrates by pyrolysis spray technique then annealed at T = 500 °C. For the preparation of films, initial solution 0.1 M tungsten oxide precursors nickel sulfate 6-hydrate cobalt chloride used. After preparing effect presence impurities structural, morphology, optical ...
The chemical states of Ni, Zn, and W in microcrystalline NiWO4–ZnWO4 solid solutions were studied by X-ray photoelectron spectroscopy. recorded spectra the Ni 2p, Zn 4f lines L2M23M45, L3M45M45, N4N67N7 Auger-transition show pronounced changes with increasing concentration. positions resolved combined to construct so-called chemical-state plots (Wagner or Auger-parameter plots) for metal ions s...
in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
در سالهای اخیر، مطالعه و بررسی درباره نانو ذره ها به دلیل کاربردهایشان گسترش بسیاری یافته است. نیکل (ii) تنگستات، یکی از مواد مهم در خانواده تنگستات ها می باشد که کاربردهای فراوان در زمینه های متنوع دارد، مانند حسگرهای رطوبتی ، کاربردهای میکروویو، فوتولومینسانس و کاربردهای کاتالیزی. در قسمت اول این پایان نامه، ترکیب niwo4 به وسیله روش میکروامولیون سنتز شد. بر این اساس، ساختار niwo4 به وسیله پرا...
Correction: Enhanced resistive switching effect upon illumination in self-assembled NiWO4 nano-nests
Raman scattering measurements and lattice-dynamics calculations have been performed on magnesium tungstate under high pressure up to 41 GPa. Experiments have been carried out under a selection of different pressure-media. The influence of non-hydrostaticity on the structural properties of MgWO4 and isomorphic compounds is examined. Under quasi-hydrostatic conditions a phase transition has been ...
