TUNGSTEN OXIDE NANOPARTICLES GROWN BY CONDENSATION IN GAS USING DOMESTIC APPLIANCES
(NORTH HOLLAND, 2011)
Tungsten oxide nanoparticles grown by condensation in gas using domestic appliances
(ELSEVIER SCIENCE BV, 2011)
Effect of lead fluoride incorporation on the structure and luminescence properties of tungsten sodium phosphate glasses
(Elsevier B.V., 2015-11-01)
Tungsten phosphate glasses are known to be promising materials for several applications in optics such as non linear optical properties, lower phonon energy or photochromic effects related with tungsten oxide incorporation ...
Influence of pre-heat treatment and different light-curing units on Vickers hardness of a microhybrid composite resin
The aim of this study was to evaluate the hardness of a dental composite resin submitted to temperature changes before photo-activation with two light-curing unite (LCUs). Five samples (4 mm in diameter and 2 mm in thickness) ...
Photochromic properties of tungstate-based glasses
(Elsevier Science BvAmsterdamHolanda, 2007)
On the preparation of clean tungsten single crystals
(ELSEVIER SCIENCE BV, 2010)
The cleaning procedure consists of two-step-flashing: (i) cycles of low power flashes T similar to 1200 K) at an oxygen partial pressure of P(o2) = 6 x 10(-8) mbar, to remove the carbon from the surface, and (ii) a single ...
Photochromic W-TiO2 membranes
(Kluwer Academic PublDordrechtHolanda, 2002)
Synthesis and evaluation of bis-b-diketonate dioxotungsten(VI) complexes as precursors for the photodeposition of WO3 films
In this paper non-stoichiometric tungsten oxide thin films have been successfully prepared by direct UV irradiation of bis-b-diketonate dioxotungsten(VI) precursor complexes spin-coated Si(1 0 0) substrates. Photodeposited ...
Low tungsten content of nanostructured material supported on carbon for the degradation of phenol
A comparative study using different mass proportions of WO3/C (1%, 5%, 10% and 15%) for H2O2 electrogeneration and subsequent phenol degradation was performed. To include the influence of the carbon substrate and the ...
Developments in hot-filament metal oxide deposition (HFMOD)
(Elsevier B.V. Sa, 2008-01-15)
Hot-filament metal oxide deposition (HFMOD) is a variant of conventional hot-filament chemical vapor deposition (HFCVD) recently developed in our laboratory and successfully used to obtain high-quality, uniform films of ...
