(Elsevier Science BvAmsterdamHolanda, 2006)
Photocurrent Response and Progesterone Degradation by Employing WO3 Films Modified with Platinum and Silver Nanoparticles
(Wiley-Blackwell, 2018-12-01)
The effect of silver (Ag-0) and platinum (Pt-0) metallic nanoparticles (NPs) on WO3 film was investigated by studying the photocurrent response under polychromatic irradiation. The structural phase revealed by X-ray ...
High gas sensor performance of WO3 nanofibers prepared by electrospinning
(2021-05-25)
WO3 is a widely studied gas sensor material that commonly exhibits excellent sensitivity and selectivity toward NO2 detection. In this study, the influence of the heating rate on the thickness and grain size of WO3 nanofibers ...
Effect of different radiopacifying agents on the physicochemical properties of white portland cement and white mineral trioxide aggregate
(2012-03-01)
Introduction: The aim of this study was to evaluate the pH, calcium ion release, setting time, and solubility of white mineral trioxide aggregate (WMTA) and white Portland cement (WPC) combined with the following radiopacifying ...
Synthesis, characterization and evaluation of the photocatalytic properties of WO3 obtained through the polyol methodSíntese, caracterização e avaliação das propriedades fotocatalíticas do WO3 obtido através do método poliol
(2021-01-01)
This work shows a synthetic route mediated by tetraethylene glycol (P. E. 325 ° C) in which tungstic acid is used as the starting material. The formation of a stable blue suspension was observed during the course of the ...

Electron beam effects on amorphous molybdenum oxide nanostructures grown by condensation in hydrogen
(2008)
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 ...
