How to improve photocatalytic performance of yellow tungsten oxide? The researchers proposed a method to improve the photocatalytic performance of yellow tungsten oxide (tungsten trioxide/ WO3). Through this method, WO3 photocatalyst showed higher photocatalytic activity than the single crystal phase WO3in the photocatalytic degradation of water to produce hydrogen and degradation of pollutants. More details, please visit: http://tungsten-oxide.com/index.html The method for improving photocatalytic performance of WO3 mentioned above is to construct heterogeneous junctions. This is also one of the effective…

It is reported that yellow tungsten oxide, is not only a typical n-type semiconductor material, but a promising semiconductor photocatalytic material. Yellow tungsten oxide, also known as tungsten trioxide or WO3, is considered to be a semiconductor photocatalytic material with great development potential due to its high solar energy utilization rate, good visible light response and strong photocorrosion resistance, and has been widely used in hydrogen production from photolysis water and catalytic degradation of organic pollutants.

What are preparation methods of yellow tungsten oxide? Or, what are preparation methods of tungsten trioxide (WO3)? There are different preparation methods for tungsten trioxide, mainly including solid phase method, liquid phase method, gas phase method, and ultrasonic chemical method. More details, please visit: http://tungsten-oxide.com/index.html Preparation Methods of Yellow Tungsten Oxide 1. Using solid phase method, process of tungsten trioxide is simple, but the prepared WO3 powder is easy to agglomerate, and its morphology cannot be well controlled. 2. Liquid…

CT tungsten alloy collimator refers to a tungsten alloy collimator used in CT scanners, mobile CT scanners and other CT equipment, which can play a role in radiation protection and radiation guidance. Wherein, the reason why tungsten alloy collimator has a radiation protection effect is that: tungsten alloy has high density, so it has excellent absorption capacity for X-rays. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html There are two tungsten alloy collimators in a CT scanner, a tungsten alloy collimator in X-ray…

Tungsten alloy collimator reduces radiation levels in CT scanning. Tungsten alloy collimator not only has the ding of collimation (X-ray guidance), but also absorbs scattered X-rays (X-ray shielding), so it can improve the image quality and can also reduce the radiation levels of CT scanning to a certain extent. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html The typical radiation dose associated with a standard CT scan ranges from 1 to 14 mSv, equivalent to the total annual dose of natural radiation that…

Tungsten alloy collimator provides the perfect solution for radiation shielding and collimation in nuclear medicine. Because tungsten alloy has excellent radiation attenuation properties, such a collimator has a reduced volume than traditional lead collimator, while it can still effectively shield harmful X-ray and gamma radiation. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html In pre-molecular imaging, tungsten alloy collimator is used to direct radiation emitted by the subject onto a detector, and to minimize the number of stray photons. Tungsten alloy collimators include…

PET-CT tungsten alloy collimator uses small amounts of radioactive materials called radiotracers or radiopharmaceuticals, a special camera and a computer to evaluate organ and tissue dings. By identifying changes at the cellular level, PET-CT may detect the early onset of disease before other imaging tests can. In general, the radioisotope used for PET-CT examination is fluorine 18. Therefore, the main radioactive hazards of this inspection are gamma rays and X-rays. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html PET-CT tungsten alloy collimator is…

γ camera tungsten alloy collimator now mostly refers to the SPECT collimator, rather than the traditional gamma camera collimator where the head cannot rotate. SPECT is a relatively new imaging system compared to traditional gamma cameras. While in any gamma camera, the role of the tungsten alloy collimator is radiation guidance and radiation protection. More details, please visit: http://www.tungsten-alloy.com/tungsten-alloy-radiation-shielding.html So, what is the main role of tungsten alloy collimator in the gamma camera? According to a certain rule, the distribution…
