Tungsten alloy leaf can be applied to multileaf collimator – an important part of medical linear accelerator. And there are many tungsten alloy leaves arranged closely to replace a whole lead block on the head of accelerator. The distance between each tungsten alloy leaf is very small. If dust particles or other dirty things settle on tungsten alloy leaves, it will cause the multileaf collimator to malding, so these leaves should be cleaned. Well, how to clean tungsten alloy leaf…

Therefore, composite semiconductor TiO2-WO3 has gradually become a research hotspot. Well, do you know how to prepare TiO2-WO3 photocatalyst? More details, please visit: http://tungsten-oxide.com/index.html Preparation of TiO2-WO3 Photocatalyst Add quantitative P25 to dilute nitric acid,…

WO3 thin film in the form of nanowires can be prepared into a gas sensor for efficient NO2 sensing. You know, NO2, mostly produced from exhaust fumes of cars and factories, has been labelled by the World Health Organization as one of the most hazardous air pollutants. Although metal oxide-based thin films have been employed to detect NO2 earlier, significant challenges remain to be addressed particularly at low detection limits. This is presumably undermined by the low surface area and…
