Morphology and phase modifications of MoO3 obtained by metallo-organic decomposition processes
(Pergamon-elsevier Science LtdOxfordInglaterra, 2010)
Simple and Friendly Sulfones Synthesis Using Aqueous Hydrogen Peroxide with a Reusable Keggin Molybdenum Heteropolyacid, Immobilized on Aminopropyl-Functionalized Silica
(Taylor & Francis, 2009-11-19)
Keggin molybdenum heteropolyacid (H3PMo12O40), immobilized on aminopropyl-functionalized silica catalysts, were made using two immobilization methods: incipient wetness and equilibrium adsorption. The material prepared for ...
Metallic Oxides as Fire Retardants and Smoke Suppressants in Flexible Poly(Vinyl Chloride)

Sol-gel synthesis of titania-alumina catalyst supports
(Elsevier B.V., 2002-08-30)
Titanium oxide is a good candidate as new support for hydrotreating (HDT) catalysts, but has the inconvenience of presenting small surface area and poor thermal stability. To overcome these handicaps TiO2-Al2O3 mixed oxides ...
Photo-electrochemical investigation of anodic oxide films on cast Ti-Mo alloys I. Anodic behaviour and effect of alloy composition
(Pergamon-Elsevier B.V. Ltd, 2009-02-01)
The anodic behaviour of cast Ti-Mo alloys, having different Mo contents (6-20 wt.%), was investigated in acidic and neutral aerated aqueous solutions. All sample showed a valve-metal behaviour, owing to formation and ...
Simple and Fast Approach for Synthesis of Reduced Graphene Oxide-MoS(2 )Hybrids for Room Temperature Gas Detection
(Ieee-inst Electrical Electronics Engineers Inc, 2018-09-01)
The combination of two highly versatile materials as reduced graphene oxide (rGO) and molybdenum disulfide (MoS2) forms the layered rGO-MoS2 hybrids that have great potential for sensing applications. In this paper, we ...
Molybdenum oxide thin films obtained by the hot-filament metal oxide deposition technique

Investigation of the metal/porcelain interface in LASER-welded Ni-Cr-Mo alloy
(2009-07-22)
The interface formed between the metal and the porcelain of laser-welded Ni-Cr-Mo alloy was studied on a metallurgical basis. The characterization was carried out by using optical microscope, electron scan microscopy and ...
