Electron beam effects on amorphous molybdenum oxide nanostructures grown by condensation in hydrogen
Molybdenum trioxide (MoO3) was evaporated from a tungsten resistive source in presence of hydrogen as carrier gas at pressures from 100 Pa to 600 Pa. Crystalline samples of molybdenum oxide were obtained at source temperatures ...
Extraction of molybdenum by a supported liquid membrane method
(ELSEVIER SCIENCE BV, 2003-04-10)
This is a report on the extraction of molybdenum(VI) ions using a supported liquid membrane, prepared by dissolving in kerosene, the extractant Alamine 336 (a long-chain tertiary amine) employed as mobile carrier. A flat ...
Molybdenum effect on the kinetic behavior of a metal hydride electrode
In the present investigation, the effect of the Mo in the LaNi3,6Co0,7Mn(0.4−x)Al0,3Mox AB5-type hydrogen storage alloys was studied. The alloys structural and microstructural characterizations were performed by means of ...
Spectrophotometric determination of Mo(VI) in steel using a homogeneous ternary solvent system after single-phase extraction
(Elsevier Science BvAmsterdamHolanda, 1998)
Effect of molybdenum on structure, microstructure and mechanical properties of biomedical Ti-20Zr-Mo alloys
Titanium has an allotropic transformation around 883 °C. Below this temperature, the crystalline structure is hexagonal close-packed (α phase), changing to body-centered cubic (β phase). Zirconium has the same allotropic ...
Electrochromism and photochromism in amorphous molybdenum oxide films
(Elsevier Science Sa LausanneLausanneSuíça, 1997)
New response in electrochemical impedance spectroscopy due to the presence of molybdenum on AB5-type alloys
(Pergamon-Elsevier Science Ltd, 2015-04)
During the present investigation, it was observed that the inclusion of molybdenum in LaNi3.6Co0.7Mn(0.4-x)Al0.3Mox AB5-type alloys produced new responses in the electrochemical impedance spectroscopy (EIS) when they are ...
Doses e formas de aplicação de molibdênio na cultura do milho
(Universidade Estadual Paulista (UNESP), 2010-12-17)
Considerando a hipótese de que a eficácia da utilização do molibdênio é dependente do ajuste em etapas importantes da determinação de sua concentração no solo, bem como da dose e forma de aplicação, realizou-se a presente ...
Molybdenum disulfide intercalates with special transport properties
(Gordon Breach, 2000)
Chemical modification of molybdenum disulfide based either in the restacking of the layered solid or the intercalation of lithium or organic donors as poly(ethylene oxide) or dialkylamines lends to products with improved ...
Synthesis and characterization of polynuclear complexes of molybdenum carbonyl derivatives with pyridine-2-carbaldehyde azine (pa) and ferrocenylphosphines. Crystal structure of [Mo2(CO)6(μ-dppf)(μ-pa)] (dppf = 1,1′-bis(diphenylphosphino)ferrocene)
(Elsevier Ltd, 1998)
Novel mono- and didentate ferrocenylphosphines containing complexes, [Mo2(CO)6(dfpp)2(μ-pa)] (dfpp = diferrocenylphenylphosphine) and [Mo2(CO)6(μ-dppf)(μ-pa)], have been isolated and characterized by infrared and electronic ...
