In-situ leaching of molybdenum and uranium is becoming an increasingly common process. The features the material composition ores, leading to a decrease in their filtration properties, were considered. Activation with solutions that have undergone electrophotochemical activation before contact ore mass studied. preparation promotes synthesis clustered water molecules collectivized protons hydro...

Bismuth–lithium alloys are considered as primary candidates for the reductive extraction step of on-line reprocessing a molten salt reactor fuel. The corrosion behavior pure metals and nickel-based was studied in liquid Bi–Li (5 mol.%) alloy at 650 °C. tantalum, molybdenum, corrosion-resistant VDM® Alloy C-4, Hastelloy® G-35®, KhN62M, 59 were prospective materials this metal media. rates determ...

Studies on the respiratory nitrate reductase (EC 1.7.99.4) from Escherichia coli K12 by electron-paramagnetic-resonance spectroscopy indicate that its molybdenum centre is comparable with that in other molybdenum-containing enzymes. Two Mo(V) signals may be observed; one shows interaction of Mo(V) with a proton exchangeable with the solvent and has: A (1H) 0.9-1.2mT; g1 = 1.999; g2=1.985; g3 = ...

With the increasingly development of automobile, electronics, aviation, spaceflight and other industries, it has put forward higher and higher requirements on the quality of molybdenum powder metallurgy products. Therefore, it is required that molybdenum powder should have better performance in chemical composition, physical morphology, average particle size, particle size distribution, apparen...

We attempted a simple pretreating method consisting of solid-phase extraction using bonded silica gel with benzenesulfonic acid (SCX) as the solid-phase sorbent to determine trace elements in pure molybdenum samples by means of inductively coupled plasma mass spectrometry (ICP-MS). Molybdenum was anionized by adding hydrogen peroxide solution to a sample decomposed with acid, and separated from...

While the existence of a molybdenum cofactor common to nitrate reductase, xanthine oxidase, and sulfite oxidase has been finnly established by studies from several laboratories (1-6), the nature of the molecule has not been elucidated. Information available to date has shown that the molybdenum cofactor complex is noncovalently attached to the proteins (2, 4) and is probably a small, dialyzable...

Industrial wastewater may contain high molybdenum concentrations, making treatment before discharge necessary. In this paper, the removal of molybdate anions from water is presented, using clinoptilolite zeolite coated with magnetite nanoparticles. In batch experiments the influence of pH, ionic strength, possible interfering (oxy)anions, temperature and contact time is investigated. Besides de...

The emerging 2D nanomaterials with unique optical properties are promising for next-generation miniatured on-chip devices. One of the prerequisites is to precisely measure their parameters during implementation. However, inherent features layers, including limited lateral dimensions and ultra-small thicknesses, not favorable conventional characterization techniques applied in bulk system, espec...
