in this study the synthesis of molybdenum oxide nano-whiskers with circular cross-section is performed. in some areas, it was observed that also some whiskers have open tips exhibiting their hollow structures. these whiskers have side dimensions ranging 2-5 μm with an average diameter in the nanometer rang. the structure suggested the vapor-liquid-solid growth mechanism (vls). scanning elect...

In this study, molybdenum-copper/alumina nano composite was synthesized with mechano-chemical method using high energy planetary ball milling. The molybdenum oxide, copper oxide and aluminum powder were used as starting materials and reaction appeared to occur through a rapid combustion reaction process. The evaluation of powder particles after different milling times was studied by X-ray diffr...

Solution-processed nanocomposites containing molybdenum oxide (MoO3) and gold nanoparticles (Au NPs) have been used as anode buffer layers in organic photovoltaic devices (OPVs). The resulting devices exhibit a remarkable enhancement in power conversion efficiency after Au NPs were incorporated into the device. Such enhancements can be attributed to the localized surface plasmon resonance induc...

Iron nanoparticles were employed to induce the synthesis of diamond on molybdenum, silicon, and quartz substrates. Diamond films were grown using conventional conditions for diamond synthesis by hot filament chemical vapor deposition, except that dispersed iron oxide nanoparticles replaced the seeding. X-ray diffraction, visible, and ultraviolet Raman Spectroscopy, energy-filtered transmission ...

Two-dimensional (2D) molybdenum oxides at their various stoichiometries are promising candidates for generating plasmon resonances in visible light range. Herein, we demonstrate plasmonic 2D molybdenum oxide flakes for gas sensing applications, in which hydrogen (H2) is selected as a model gas. The 2D molybdenum oxide flakes are obtained using a grinding-assisted liquid exfoliation method and e...

One-, two- and three-dimensional nanostructures of copper molybdenum oxide hydroxide were successfully constructed by a simple approach through a pH-dependent dimensional transformation of ammonium copper molybdate. Thin nanoplates of copper molybdate, which were obtained by sintering the two-dimensional nanobelts of copper molybdenum oxide hydroxide, exhibited remarkably high reversible lithiu...

Molybdenum disulfide (MoS2)-based materials have been recently identified as promising electrocatalysts for hydrogen evolution reaction (HER). However, little work has been done to improve the catalytic performance of MoS2 toward HER in alkaline electrolytes, which is more suitable for water splitting in large-scale applications. Here, it is reported that the hybridization of 0D nickel hydr(oxy...

BACKGROUND: The expanding scope of molybdenum (VI) oxide (MoO3 NPs) nanoparticle application has increased the risk developing pathological disorders in exposed population due to negative effects this nanomaterial. As such, there is a need assess potential hazard MoO3 NPs human health.
 AIM: To determine degree danger nanoparticles for MATERIAL AND METHODS: was assessed accordance with MR ...

in order to study the effect of vermicompost containing copper oxide and zinc oxide nanoparticles on was beans, in an experiment factorial were done based on a randomized complete block design in three replications. the experiment treatment were as follows: nanoparticles in 4 levels (0, 0.4, 0.8 and 1.2 g/kg weight of substrate), vermicompost in 3 levels (2.5, 5 and 7.5 g/kg-1 weight of substra...
