Tungsten Oxide

A WO 3 –graphene photocatalyst has been developed that can degrade the dye Rhodamine B almost completely in 15 minutes. This is much faster than the degradation times that can be achieved by bare WO 3  or TiO 2 . The catalyst consists of a porous WO 3  framework with a graphene film and is directly produced via electrospinning. The authors from China and the USA envision that this potent electrocatalyst can be used in environmental applications for the degradation of pollutants under visible light. The superior properties of the photocatalyst can be explained by its components and structure. The WO 3  nanoframework efficiently absorbs visible light due to multiple reflections in the pores. A rapid charge transfer to graphene takes place, which avoids charge recombination. Additionally, graphene nanosheets are exposed on the surface. This enables π–π conjugation between graphene and dyes leading to high adsorption rates of the substrate on the catalyst material. These combined prop

Sewer is the integral part of infrastructure in a city which plays an irreplaceable role in the living environment of safety, construction and comfortable. In recent years, the corrosion degradation has caused many social problems, such as the collapse of the road, and thus attracted widespread attention.   Sewer corrosion mainly brought out by the oxidation of sulfur-oxidizing bacteria and generated the sulfuric acid and hydrogen sulfide which constantly corrode the pipe surface. In the past, anti-corrosion protection of concrete structures sewer facility is mainly used in the surface coating or a coating method for coating a sheet of resin-based material. These methods have a big challenge in terms of construction; besides, the adhesion and anti-scratch is weak; with relatively short life (only 3 to 6 years). Therefore, a new material with strong anti-corrosion is called.   Recently, studies have shown that tungsten oxide and nickel as the antimicrobial agent doped in the c

Curtains have been around for many years without much improvement. The small advances that have been made, such as motorized shades and smart glass, can be extremely expensive and complex to install. Latest, the smart glass window Wi-Fi enabled has been invented. According to the manufacturer, this kind of film maybe revolutionizes the industry of windows and curtains. So, you may ask: what is digital shade? Digital shade (or smart film) is a technology that allows the color of the film to go from transparent to non-transparent when you apply a current through it, also the level of transparency is able to control. The tungsten oxide smart glass window film with Wi-Fi will give you the option for privacy on demand by adjusting the amount of light traveling through your glass window; and with the multi-purpose, it can used in the commercial, home use, such as meeting rooms, offices, living room, dining room and bathrooms.   The tungsten oxide smart film is based on digital sha

In tungsten oxide smart glass, the electrochromic material changes its opacity: it changes between a colored, translucent state (usually blue) and a transparent state. A burst of electricity is required for changing its opacity, but once the change has been effected, no electricity is needed for maintaining the particular shade which has been reached. Darkening occurs from the edges, moving inward, and is a slow process, ranging from many seconds to several minutes depending on window size. Electrochromic glass provides visibility even in the darkened state and thus preserves visible contact with the outside environment. It has been used in small-scale applications such as rearview mirrors. Electrochromic technology also finds use in indoor applications, for example, for protection of objects under the glass of museum display cases and picture frame glass from the damaging effects of the UV and visible wavelengths of artificial light.
