As aγ-ray shielding material, WO3-Bi2O3 composite material can reduce the damage of γ-rays to human body, equipment and environment to a certain extent, so that it may be applied to aerospace engineering, especially the manned space flight project. Some experts filled the natural rubber with WO3 and Bi2O3 nanoparticles with the same mass fraction (30%) and different proportions, and prepared the composite gamma-ray shielding materials, respectively. More details, please visit: http://tungsten-oxide.com/index.html The results showed that the particle size of WO3…

Tungsten oxide nanopowder may be compounded with natural rubber to obtain a gamma ray shielding material with excellent mechanical properties and γ-ray shielding properties. You know, γ-rays have been widely used in nuclear facilities, aerospace, and radiomedicine fields, with short wavelengths and large energy, which have serious harm to the human body. Therefore, the shielding of γ-rays has received much attention. Traditional shielding materials, such as lead-containing plates and glass are heavy with high mobility and low shielding rates, which…

Hexagonal tungsten oxide is the most used materials for producing gas sensor. And the obtained gas sensor is mainly for hazardous gas detection. More details, please visit: http://tungsten-oxide.com/index.html According to the experts, they have prepared hexagonal tungsten oxide via a soft chemical nanocrystalline processing route, and studied the structure of parent phases by scanning and transmission electron microscopy and X-Ray diffraction. Also, they determined the electrochemical behavior of the films by atomic force microscopy and cyclic voltammetry. Besides, they tested…

Tungsten trioxide crystal is a material with electrical transport properties, which can be prepared by vapor phase transport and annealed under varying conditions. Well, do you know what the effects of oxygen-deficiency on electrical transport properties of tungsten trioxide crystals are? More details, please visit: http://tungsten-oxide.com/index.html According to the experts, the jump in resistivity at the monoclinic-triclinic transition is due mainly to a decrease in electron mobility. The change at the triclinic transition is almost entirely the result of a…

Monoclinic tungsten trioxide is one of the crystal structure of tungsten trioxide. According to the researchers, they have studied the crystal structure of tungsten trioxide at room temperature by the X-ray oscillation method. More details, please visit: http://tungsten-oxide.com/index.html And it was found that the tungsten trioxide crystal at room temperature has a monoclinic unit cell with a =7.30 ?, b =7.53 ?, c =7.68 ? and β=90°54′, containing eight molecules of WO3. That is to say, the crystal structure of…

WO3 is an electrochromic material, TiO2 also possesses electrochromic properties that have attracted many research and development interests, so electrochromic phenomenon occurs on the TiO2-WO3 composite film. According to the experts, though WO3 exhibits excellent electrochromic properties, the much higher cost and water-sensitivity of WO3 as compared with the TiO2 may restrict the practical application of WO3 materials. In this regard, some experts have prepared nanocrystalline TiO2-WO3 composite films. Wherein, WO3 is amorphous. More details, please visit: http://tungsten-oxide.com/index.html The experts…
