Automatic tungsten alloy radiation shielding door is more and more popular as it is one of the effective measures to solve medical radiation pollution. There is radiation in CT room, radiation oncology room, etc. Therefore, in addition to the installation of radiation shielding parts in the diagnostic equipment in these rooms, a fully automatic tungsten alloy radiation shielding door is necessary, to protect the medical staff and patients outside the door from radiation pollution.

Why do we need tungsten medical radiation shielding? You know, there are more and more radiation equipment appearing in our life with the development of medical technology. And these pieces of medical equipment have a significant influence on our lives. While the radiation therapy equipment such as linear accelerators, cobalt 60 and X-ray detectors work by emitting radiation sources. So it is important to protect people from the harm of radiation sources such as X-rays, gamma rays, alpha particles, and beta particles, etc.

Preparation of defective tungsten oxide nanopowder is widely studied as defective tungsten oxide nano powder has wide applications in solar power generation, seawater desalination, and sewage treatment. Defective tungsten oxide nanopowder is a kind of photothermal conversion material, which can convert sunlight into heat energy to heat the base liquid, and realize the photothermal conversion. Specifically, the application of tungsten oxide nanoparticles is to convert water into steam on a large scale under the radiation of the sun or solar simulator to achieve solar power generation, seawater desalination, or sewage treatment. Well, do you know how to prepare defective tungsten oxide nanoparticles?

WO3, an n-type semiconductor, is an excellent gas-sensing material and has good sensitivity to toxic gases such as NO2. According to the experts, in recent years, with the rapid development of economy and industry, toxic gases such as NO2 have caused serious environmental pollution problems, such as acid rain, photochemical smog, etc. Due to their toxicity and destructiveness, the detection of NO2 and other toxic gases has paid much attention.

WO3 nanoparticles are often made into gas sensor for detecting various toxic gases. For example, WO3 nano particles have high sensitivity and selectivity to trimethylamine and high sensitivity to acetic acid, acetaldehyde, acetone, and ethanol gas.

WO3 nanopowder is n-type semiconductor that has wide applications in smart windows, gas sensors, etc., so it has been paid much attention including its preparation. Here is a preparation method of WO3 nanopowder.

WO3 nanopowder is a typical n-type gas-sensing material that has high sensitivity and selectivity to toxic gases, so it has a wide application in gas sensor to detect various hazardous gases. Especially for trimethylamine gas, the reaction is rapid, and the sensitivity is very high. It means that the WO3-based gas sensor provides a quick, convenient, and accurate detection method for detecting whether fish or shellfish food has deteriorated. Also, the gas sensor based on WO3 nano particles has the advantages of low power consumption, low cost and convenient operation. So, WO3 has attracted much attention.

As a semiconductor gas sensing film material, WO3 film has good sensitivity to NOx, H2S, H2, CH4, C2H5OH, CO, NH3 and other gases, so it has broad application prospects. Therefore, the preparation of WO3 film has been paid much attention. Here is a preparation method of WO3 film.

WO3 film, an n-type semiconductor, is used as an excellent thin film gas-sensing element in applications of gas sensors. You know, WO3 is a typical n-type gas sensing material that has attracted considerable attention to detect various hazardous gases, in the form of nano particles or thin films.

As a gas sensing material, WO3 on the nanoscale has good gas sensitivity and selectivity towards H2, CO, H2S, NH3, NOx, O3 as well as some organic gases. WO3 nano powder is a typical n-type semiconductor that is considered to be the promising material to fabricate the gas sensor, which has a widespread utilization in the environment detecting and the safety monitoring. When WO3 nanopowder contacts the gas to be measured, its resistance changes, so that the output signal changes accordingly to achieve the purpose of gas detection.
