Yellow tungsten oxide nanocomposite film may be a nanocomposite film of polyainline (PANI) and tungsten trioxide (WO3), which may be fabricated by electropolymerization of aniline monomers onto WO3 coated ITO glass slides through spin coating technique and followed by annealing at 500 °C for 2h.

Yellow tungsten oxide nanowires have excellent gas sensitivity so that they are often used to prepare gas sensor. According to the experts, yellow tungsten oxide nanowires and silicon nanowires can be combined to obtain silicon nanowires - tungsten oxide nanowires composite structure, whose interface forms a homogeneous heterojunction. In NO2 gas, the increase of the width of the depletion layer in the heterojunction has an important effect on the improvement of its gas sensing performance.

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.

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 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.

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?

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.

Tungsten oxide is developed as a battery electrode. It has been reported that tungsten oxide electrode material enables ultra-fast charging and discharging. So, it is often used as an anode material for lithium ion batteries. And it has a wide range of applications where a large current or capacity is required, such as uninterruptible power supplies (UPS), large current sources, and power supply stabilizers, etc. Also, it has applications with a focus on energy regeneration properties such as elevators, micro/mild hybrid vehicles and trains.

Yellow tungsten oxide is a well-known γ-ray shielding material with the chemical formula of WO3. It has been reported that WO3 can be compounded with natural rubber (NR) to obtain NR-WO3 composite materials. Some experts adopt hydrothermal method to synthesize Bi2WO6 nanoparticles and obtain WO3 and Bi2O3 particles with similar particle size by ball milling. And they fill these particles into natural rubber with a total mass fraction of 30% to prepare NR-Bi2WO6, NR-WO3 and NR-Bi2O3 composite material.

As a radiation shielding material, Er2O3-WO3-epoxy resin can reduce the damage of radiation to human body, equipment and environment. Some experts have prepared Er2O3-WO3-epoxy resin composites using Er2O3 and WO3 as radiation shielding functional particles and epoxy resin as the matrix. Also, they performed detailed testing and characterization of their microstructure, mechanical properties, and radiation shielding properties.
