Molybdenum dioxide (MoO2) is known for its catalytic activity toward reforming hydrocarbons. The objective of this study was to evaluate the effect of biofield energy treatment on physical, thermal, and structural properties in MoO2. The MoO2 powder sample was divided into two parts, one part was remained as untreated, called as control, while the other part was subjected to Mr. Trivedi’s biofield energy treatment and called as treated. Both control and treated samples were investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), and Fourier transform infrared (FT-IR

ABSTRACTMoO2-Fe2O3 nanoparticle system was successfully synthesized by mechanochemical activation of MoO2 and α-Fe2O3 equimolar mixtures for 0-12 hours of ball milling time. The study aims at exploring the formation of magnetic oxide semiconductors at the nanoscale. X-ray powder diffraction (XRD), Mössbauer spectroscopy and magnetic measurements were used to study the phase evolution of MoO2-Fe2O3 nanoparticle system under the mechanochemical activation process. The Mössbauer studies showed that the spectrum of the mechanochemically activated composites evolved from a sextet for hematite to se

Molybdenum, valued for its high melting point and exceptional physical and chemical properties, is studied in diverse fields such as electronics, petrochemicals, and aviation. Among molybdenum oxides, molybdenum dioxide stands out for its higher electrical conductivity than other transition metal oxides due to its structural characteristics, exhibiting metallic properties. It is applied as pellets to gas sensors, semiconductors, and secondary batteries for its properties. Thus, research on molybdenum dioxide compaction and pressureless sintering is necessary, yet research on pressureless sinte

Results of the sludge samples analyses reveal a chemical composition typical of black powder: Magnetite (Fe3O4), Goethite (γ-FeOOH) and trace amounts of Quartz (SiO2). By process of elimination, pipeline loops were the suspected source of these solids. The results show that Fe3O4 is the main component which normally originates in these cases from a process of dissolved oxygen corrosion due to the presence of very small amounts of oxyge

The properties of thermal sprayed coatings depend mainly on the kinetic and thermal energy of sprayed particles, i.e., a higher particle velocity causes an increase of coating quality.

Abstract Molybdenum silicides have the potential as protective coatings for high-temperature applications because of their high melting point and their high-temperature oxidation resistance. Reinforcing MoSi2 with SiC shows an improvement of its low toughness at room temperature and low creep resistance at temperatures above the brittle-ductile transition temperature of approximately 700-1000 °C.

Abstract In order to facilitate the dissolution of these insoluble nuclear debris from the Fukushima accident, it is necessary to investigate methods of pulverizing them to increase their surface area.

We therefore developed non-equilibrium plasma oxidation device to verify the powderization of uranium dioxide solids and to compare the resul

Therefore, cold spraying is a well-established method for metal on metal coatings. However, few authors have investigated the impact phenomena and layer formation process for impacting brittle ceramic particles on ductile metal surfaces. For this study, titanium dioxide (TiO2) on metal surfaces was chosen as a model system, and layer formation on aluminum, copper, titanium and steel substrates was investigated by SEM, TEM, XRD and Raman spectroscopy.
