Yellow tungsten oxide nanowires are considered to be the most promising semiconductor gas-sensing material, which can be used to prepare NO2 gas sensors. As we all know, air pollution is an important aspect of environmental pollution, and NO2 gas in the air will cause serious damage to human body. Therefore, the preparation of a gas sensor that can work at room temperature with low energy consumption and high sensitivity has attracted the attention of many researchers.

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 can no longer meet people's needs. Therefore, it is urgent to develop low-toxic, lightweight and efficient gamma ray shielding materials.

Yellow tungsten oxide for smart dimming glass is tungsten trioxide - an electrochromic material that is considered to be one of the most promising smart materials. Among many electrochromic materials, as the most common inorganic cathode electrochromic material, yellow tungsten oxide has the advantages of being cheap, non-toxic and stable with superior performance so that it has received wide attention.

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?
