Considerable interest in tungsten oxide polymorphs (WO_3-x) nanomaterials has been generated due to their abundance in nature, easy availability, high stability, non-recombination, and chemical diversity, and many advances have been made from traditional catalysts and electronics to emerging artificial intelligence. A recent study from Qingdao University presents the latest progress of WO_3-x polycrystals and their multifunctional applications.

A recent study conducted by the Anhui University of Technology has proposed new measures for the oxidation protection of tungsten alloys in nuclear fusion applications. As a plasma guide material (PFM), tungsten is persistently used in nuclear fusion reactors. However, it has poor oxidation resistance at high temperatures. When a reactor de-cooling accident occurs, tungsten is rapidly oxidized and volatilized due to air entering the vacuum chamber, which may cause a catastrophic nuclear leakage accident.

A study conducted by researchers at the University of Utah in Salt Lake City, Utah, USA, describes ways to improve tungsten ductility. It is generally accepted that pure tungsten and tungsten alloys with minor alloy additions are brittle at room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving the ductility of tungsten is important in generating the range of tungsten manufacturing and applications.

Researchers at the University of California have conducted a study on the effect of tungstate on nitrate reduction in Pyrobaculum aerophilum, a hyperthermophilic archaeon that can respire both at low levels of oxygen and anaerobically with nitrate as the electron acceptor. Under anaerobic growth conditions, nitrate is reduced to molecular nitrogen via the denitrification pathway.

A study conducted by researchers at Daegu Catholic University in South Korea introduces advanced methods that combine chemical vapor transport (CVT) with quenching effects to create molybdenum oxide nanoparticle aggregates arrays consisting of fine nanoparticles (NPs) in a layered structure, grown vertically on individual carbon fibers of a carbon fiber paper (CFP) substrate.

A recent study carried out by Yu Jiang et al at Jiangsu Key Laboratory of Thin Films, Soochow University, Suzhou, China has investigated the Molybdenum-based materials for sodium ion batteries (SIBs). SIBs are considered to be one of the most promising candidates for energy storage required for renewable energy sources. The main difficulty is finding a suitable anode material, and molybdenum-based materials are expected to solve this problem.

Researchers from Morocco have investigated the Dirac electron scattering problem in quantum dots of monolayer molybdenum disulfide (MoS₂) quantum dots subject to magnetic flux. Analytical expressions for the eigenstates, scattering coefficients, scattering efficiency, and radial component of the reflected electron flow were developed by solving the Dirac equation.

Researchers from the University of Pittsburgh recently enhanced the photoelectrochemical (PEC) water splitting capability of bilayer photoanode nanotubes through simple but effective molybdenum (Mo) doping method.

In a study led by researchers at the School of Chemical Studies, Jiwaji University, India, novel growth of WO₃-ZnSe nanocomposites was performed under subcritical conditions by a simple, low-cost hydrothermal process, and the first characterization of the products-completed in just 5 hours is reported: X-ray diffraction, scanning electron microscopy (SEM), optical studies and Fourier transform analysis.

Researchers from Tokyo Metropolitan University have created a new tungsten (W) substituted vanadium oxide catalyst for breaking down harmful nitrogen oxides in industrial exhaust gases. Their new material is able to operate at lower temperatures and does not exhibit a significant degradation in performance when treating "wet" exhaust gases, addressing a major drawback of conventional vanadium oxide catalysts. The researchers also found that the non-aggregated dispersion of atomic tungsten in the original crystal structure plays a key role in its function.
