BACKGROUND The importance of molybdenum for plant growth is disproportionate with respect to the absolute amounts required by most plants. Apart from Cu, Mo is the least abundant essential micronutrient found in most plant tissues and is often set as the base from which all other nutrients are compared and measured. Molybdenum is utilized by selected enzymes to carry out redox reactions. Enzyme...

Abstract We report the hydrogenation catalytic activity application of molybdenum–ruthenium (MoRu) solid‐solution alloy nanoparticles (NPs) as catalysts for 1‐octene and 1‐octyne. The structure MoRu NPs was confirmed through scanning transmission electron microscopy (STEM) coupled with energy‐dispersive X‐ray spectroscopy (EDX), powder diffraction (PXRD) measurement. these toward 1‐octyne in te...

The influence of heat treatment time and temperature on the microstructure and corrosion resistance of cast stainless steel alloys CN3MN (UNS J94651) and CK3MCuN (UNS J93254) were investigated with a combination of microscopy techniques and immersion corrosion testing. The as-cast alloys exhibited significant residual microsegregation of Mo across the dendritic substructure and the presence of ...

In India, urban solid waste generation has risen over the last decade. The aspect of is a large amount materials among all types. While using ash particles eliminates waste, it also contributes desirable qualities. this research work, effects Himalayan nettle leaf (HNLA) and bean pod (BPA) with molybdenum trioxide (MoO3) on ZWK611 (Mg–Zn6.0–Y1.2–Zr0.2) alloy examined. as-cast exhibits an α-Mg m...

In this study, Nickel-Chrome-Molybdenum alloy is manufactured using investment casting method with centrifugal device from a polyurethane foam model in regular and open-pore form, as hard tissue implant. The samples produced have 10, 20, 30 (±3) pores per inch 0.0008, 0.0017, 0.0027 g/mm3 densities, respectively. Young’s modulus, hardness mechanical behaviors of the were investigated by SEM, ED...

The molybdenum‑titanium‑zirconium‑carbon alloy TZM is one of the few molybdenum alloys that can be processed crack-free in laser powder bed fusion (LPBF). However, parts have a coarse-grained, columnar microstructure comprising epitaxially grown grains, and their strength limited by residual porosity. Consequently, mechanical properties do not reach values conventionally powder-metallurgically ...

Boron-doped molybdenum silicides have been already recognized as attractive candidates for space and ground ultra-high-temperature applications far beyond limits of state-of-the-art nickel-based superalloys. In this work, we are exploring a new method fabricating Mo–Si–B alloys (as coatings or small bulk components) by utilizing pressure-less reactive melt infiltration approach. The basic assum...

A chitosan resin functionalized with 3-nitro-4-amino benzoic acid moiety (CCTS-NABA resin) was newly synthesized for the collection/concentration of trace molybdenum by using cross-linked chitosan (CCTS) as base material. The carboxyl group of the moiety was chemically attached to amino group of cross-linked chitosan through amide bond formation. The adsorption behavior of molybdenum as well as...

The objectives of this study were to determine physiologic adaptations that occur when humans are exposed to a wide range of molybdenum intake levels and to identify the pathways that are influenced by dietary intake. Four males consumed each of 5 daily molybdenum intakes of 22, 72, 121, 467, and 1490 microg/d (0.23, 0.75, 1.3, 4.9, and 15.5 micromol/d) for 24 d each. During each treatment peri...
