Photocatalytic decolorization of Methyl Orange (MO) solution has been studied using phosphotungstic acid (HPA) as photocatalyst. The decolorization reaction of MO solution is photocatalysis. The paper reveals that the optimal loading of photocatalyst for decolorization of MO solution (10 mg/L) is 0.6 g/L. The results show that the photocatalytic decolorization reaction of MO with HPA in a h...
A organic-solution-processable functionalized-graphene (SPFGraphene) material has been studied on pre-concentration and determination of trace Mo(II)ions. In this process, the effects of pH solution, elution conditions on pre-concentration of trace Mo(II) were studied and the effect of interfering ions was also investigated. A selective method for the fast determination of trace amounts of Mo (...

The voltammetric characteristics of Mo (VI) oxinate at the mercury electrode, in the presence of tri-butylammonium perchlorate (tri-BAP) and piperidinium perchlorate (PP) + piperidine (P) as two different types supporting electrolytes, have been studied in chloroform. With the both supporting electrolytes a two electron irreversible process for the reduction of Mo (VI) oxinate was observe...
ترکیب بین فلزی mosi2 به دلیل نقطه ذوب بسیار بالا، چگالی نسبتاً پایین، هدایت الکتریکی و حرارتی خوب و مقاومت به اکسیداسیون عالی در دماهای بالاتر از ?c 1000 یکی از مهمترین ترکیبات بین فلزی سیلیسایدی است. با این حال، چقرمگی شکست mosi2 پایین می باشد و برای بهبود آن از ذرات تقویت کننده zro2 استفاده شده است. هدف از این پژوهش، بررسی امکان تشکیل ترکیب بین فلزی mosi2 و کامپوزیت mosi2-zro2 با استفاده از فر...
myositis ossificans (mo) is a pathologic bone formation in soft tissue with unknown pathogenesis. in this article, we reported a case of long standing mo of right medial pterygoid muscle with severe limitation of mouth opening.
Mo-doped SnO2 nanoparticles were prepared using hydrothermal method. The average grain size obtained by varying calcinations temperature from 160 to 500 oC showed the different sizes. Prepared materials characterized by X-Ray diffraction (XRD) and scanning electron microscopy (SEM). Also the FTIR and the UV–Vis absorptive spectra have been carried out. Mo- doped SnO...
Carbothermic reduction of Molybdenite in the presence of Magnesium oxide was thermodynamically studied. The stability diagrams for MoS2-MgO and MoS2-MgO-C Systems was prepared. The reduction of MoS2 with Carbon in the presence of Magnesium oxide proceeded through the direct oxidation of MoS2 by MgO to form intermediate molybdenum oxidized Species, MoO2 and MgMoO4. The results showed that the g...
