Reduction of the manufacturing cost titanium and development new alloys are crucial to effectively harvest benefits derived by use in industrial applications. Therefore, we considered creation Ti-2X-2Z via combined lean additions isomorphous (i.e. Nb) eutectoid Cu, Mn, Fe) beta stabilisers, systematically analysed their effect on manufacturability mechanical response produced powder metallurgy....

Friction composites consist of many materials with various properties. Solid lubricant is one these materials. The task the solid in compo-site to protect counter surfaces against wear and reduce noise vibra-tion. Typical lubricants used friction composite are graphite, antimo-ny trisulfide, molybdenum disulfide, copper sulfide, etc. selection suitable for better braking performance an importan...

Background: Technetium-99m radioisotope is the backbone of any nuclear medicine institute. This radioisotope is acquired by the elution of Molybdenum-99/Technetium-99m generator which emits 141 keV gamma ray and having 6.04 hour half-life. Occasionally the contents of Molybdenum-99 may mix up with elute, which may affect image quality and patients may receive higher doses than recommended. This...

The relationship between plasma molybdenum (Mo) and dietary intake has not been investigated in humans. We developed an isotope dilution method to determine molybdenum in 0.5 mL blood plasma by ICP-MS and conducted a study to determine the effect of dietary intake on plasma molybdenum. Twelve young men consumed a very low Mo diet (22 microg/day) for 24 days while confined to the WHNRC metabolic...

The assimilatory nitrate reductase from Chlorella contains flavin, heme, and molybdenum as prosthetic groups. The molybdenum in assimilatory nitrate reductase is associated with a pterin moiety (molybdopterin) as evidenced by the ability of the enzyme to donate active molybdenum cofactor to the Neurospora nitrate reductase mutant nit-1 and by the oxidative conversion of the pterin to two well c...

Mining and metallurgy have negative consequences for the environment [1-3] and lead to changes in geological [4] and climatic conditions [5]. Mining-metallurgy operations include the extraction, preparing of ores (crushing ore and flotation), processing of concentrates, and the disposal of waste rock and by-products. The main waste in mining and metallurgy are waste rocks, flotation tailings an...
