Electrical switching in the MoO3–WO3–P2O5 and MoO3–P2O5 glasses
Ionics, 2009High field electrical switching on blown films of MoO3(60%)–P2O5(40%), MoO3(50%)–WO3(10%)–P2O5(40%), and MoO3(45%)–WO3(15%)–P2O5(40%) having different thicknesses was studied and compared. Switching was observed using two terminal samples. S-type current–voltage characteristic (current-controlled negative resistance—CCNR) with memory was observed in ...

Deactivation studies on NiO-MoO3/Al2O3 and CoO-MoO3/Al2O3hydrodesulphurization catalysts
Studies in Surface Science and Catalysis, 1997The results of comparative investigation of NiO-MoO 3 /γ-Al 2 O 3 hydrodesulphurization (HDS) catalyst deactivation in industrial plant and laboratory conditions are presented. Structural (XRD, DRS, XPS), textural (LTNA) and morphological (SEM) characteristics were followed depending on temperature, time of treatment and the atmosphere of regeneration.

Transparent organic light-emitting devices using a MoO3/Ag/MoO3 cathode
Journal of Applied Physics, 2011MoO3/Ag/MoO3 (MAM) stacks are investigated for utilization as transparent cathodes in organic light-emitting devices (OLEDs). The stacks can be fabricated using simple thermal evaporation at relatively low temperatures, and can be readily and safely utilized as top electrodes, without causing deposition damage to the organic layers.

Photoaccumulating film systems based on TiO2/MoO3 and TiO2/MoO3:V2O5 nanoheterostructures
Russian Journal of Physical Chemistry B, 2017The thin-film photocatalysts TiO2/MoO3 and TiO2/MoO3:V2O5 obtained by a combination of sol–gel and sintering techniques were studied using the photooxidation of probing dyes, EPR spectroscopy, X-ray diffraction analysis, and electron microscopy. It was shown that due to charge accumulation caused by UV irradiation, these photocatalysts retain their ...

Optical properties of MoO3/Ag/MoO3 multilayer structures determined using spectroscopic ellipsometry
Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 2019The authors investigated the optical and electrical properties of MoO3/Ag/MoO3 multilayer structures grown using thermal evaporation on glass. For the top and bottom MoO3 layers, they found that thicknesses of 35 and 20 nm, respectively, gave the highest transmittance in the visible spectral range.

?????????????? ???????????????????????????????? ?????????????????? ???? ???????????????? MoO3
2012It is shown that the mechanochemical treatment of MoO3 in various media allows one to change a oxide crystalline modification and the relative content of its crystallographic planes. An increase of the surface area and a reduction of the particle sizes are determined. As a result, the catalysts with high selectivity at the C2H5OH oxidation are obtained.
