A research team from the Taiwan University of Science and Technology has published a paper in Frontiers in Materials on the progress of tungsten-oxide-based material applications. Tungsten-oxide-based material has received great attention due to its ability to absorb near-infrared (NIR) light and its efficient photothermal conversion properties.

The research team at Yingkou Institute of Technology and Georgia Institute of Technology recently presented their latest work describing the structure and antimicrobial properties of thin-film coatings based on tungsten oxide materials on stainless steel substrates.

Molybdenum wires are common molybdenum product. If classified by material, molybdenum wire can be divided into pure molybdenum wire, high-temperature molybdenum wire, sprayed molybdenum wire, and wire-cut molybdenum wire and different types of molybdenum wire have different characteristics and their applications are also varied.

In organic chemistry, sodium tungstate (Na₂WO₄) is used as a catalyst for the epoxidation of alkenes and the oxidation of alcohols to aldehydes or ketones, and sodium tungstate particles are also known for their anti-diabetic effects; researchers have identified pathways by which sodium tungstate improves pancreatic function and beta-cell proliferation.

Tungsten (W) is a durable, strong metal used to make rings and other jewelry. The word tungsten originates from the Swedish word meaning heavy stone. It is a steel-gray material with the highest strength of any known metal, and it’s only one point lower than diamond on the Mohrs Hardness Scale.

Tungsten alloy has the advantages of high density, machinability, good corrosion resistance, and high radiation absorption capacity, and high strength. It is widely used in the fields of aerospace and automotive industries and radiation shielding.

A study at the University of Queensland has shown that tungsten and molybdenum (Mo) can improve the electrochemical properties of the cathode materials in Li batteries. As the driving range of electric vehicles increases, more nickel is needed to increase energy density, but this also reduces cycle stability. Tungsten and Mo improve stability by enhancing structural stability and resistance of the cathode material surface layer to electrode/electrolyte side reactions.

A study conducted by researchers at the University of Queensland has shown that the specific properties of metallic materials such as tungsten (W) and molybdenum (Mo) could improve the electrochemical properties, especially the cycle stability, of cathode materials in Li batteries. Ni–Co–Mn ternary oxide materials (NCMs) and Ni–Co–Al materials (NCAs) are widely used as cathodes in lithium ions for electric vehicles. Increasing the driving range of electric vehicles necessitates a raise of the nickel content to increase the energy density, which, however, degrades the cycle stability.

Among the transition metal oxides, tungsten trioxide (WO3) has attracted much attention and has been widely studied due to its many interesting structures and defect characteristics. The numerous applications of WO3 optical and electronic devices include electrochromic (EC) smart windows, flat panel displays, tunable EC photonic crystals, and gas sensors. However, its higher band gap energy (2.6-3.6 eV) limits its application. Therefore, the low frequency near infrared light (NIR) cannot be blocked.

Electrochromism (EC) is a phenomenon that induces a reversible optical change (coloration/bleaching) in a material by applying a small electric field. Tungsten oxide (WO3) is the most widely studied electrochromic material due to its outstanding electrochromic (EC) properties. Materials that can continuously and reversibly change color under reversible electrochemical processes are called electrochromic materials, which have been widely used to fabricate light modulation devices. Among these devices, anti-glare car mirrors have been commercialized, and smart windows are currently driving intensive development.
