The potential of Ru/CeO2 catalysts to catalyze the synthesis ammonia from renewable hydrogen was explored under ambient and high-pressure conditions. Different types Ru precursors, CeO2, their combinations strongly influenced NH3 activity. catalytic activities Ru(acac)3 Ru(NO)(NO3)3 were relatively high at pressure. activity 1 wt% with as a precursor studied dependence on temperature, pressure,...

in this research, we investigated the glottal wave of persian vowels, using electroglottography. in the first level, the properties of vowels glottal wave were analyzed. in the second level, the glottal wave between male and female speakers were  compared. contact quotient is the glottal wave parameter which was analyzed. data included six persian vowels and the glottal wave recorded using elec...

The encapsulation of homogeneous chiral catalysts, e.g. Co(Salen) and Ru-TsDPEN, in the mesoporous cage of SBA-16 is demonstrated; the encapsulated catalysts show performance as good as that of the homogeneous catalysts, and can be recycled for more than 10 times without significant loss of catalytic performance.

Magnetoresistive sensors have been enthusiastically selected for applications requiring magnetic field detection with small footprint sensors. The optimisation of the sensor response includes using soft free layers, based on CoFeB and NiFe alloys. Here we report TMR noise performance magnetically saturated in-plane MTJ including CoFeBTa CoFeSiB films as layers (FL). Assessing magneto-crystallin...

hybrid nanocomposites of binary pt-ru/polyaniline were prepared by oxidative polymerization of aniline andformation pt and ru nanoparticles. the polymerization of aniline was carried out in the presence of potassiumhexa cyano platinate (iv) and ruthenium (iii) nitrosyl nitrate as oxidizing agents. during the reaction anilinemonomers undergo oxidation and form polyaniline (pani) whereas the redu...

Development of L10 FePd thin films with large bulk perpendicular magnetic anisotropy and a low damping constant may permit superior scaling next-generation ultra-high density memory elements. The buffer layer influences the L10-order parameter, static dynamic properties demands consideration for design high strength films. In this report, we systematically investigate engineered through Cr/(Pt,...

The hydrogenation of CO2 to methanol can be achieved using a single molecular organometallic catalyst. Whereas homogeneous catalysts were previously believed to allow the hydrogenation only via formate esters as stable intermediates, the present mechanistic study demonstrates that the multistep transformation can occur directly on the Ru–Triphos (Triphos 1⁄4 1,1,1-tris(diphenylphosphinomethyl) ...

The polymerization of aniline was carried out in the presence of Potassiumhexa cyano Platinate (IV) and Ruthenium (III) nitrosyl nitrate as oxidizing agents. During the reaction anilinemonomers undergo oxidation and form polyaniline (PANi) whereas the redu...

In previous studies, the neuroprotective effect of progestrone in diffuse traumatic brain injury has been shown. This study used mifepristone (RU-486), a potent progesterone receptor antagonist, to evaluatethe hypothesis that the neuroprotective effect of progesterone in traumatic brain injury is mediated by the progesterone receptors. The ovariectomized rats were divided into 6 groups. Brain i...

Despite numerous works devoted to the cellulose hydrogenolysis process, only some of them describe reaction kinetics. This is explained by complexity process and simultaneous behavior different reactions. In this work, we present results kinetic study glucose into ethylene- propylene glycols in presence Ru@Fe3O4/HPS catalyst as a part catalytic conversion glycols. The structure Ru-containing ma...
