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.

The application of ultrasound (US) as a green activation method for the chemical conversion of tungstate catalyst to oxidize alcohols to aldehydes has attracted chemists’ interest.

Recently, researchers from Jiujiang University and the University of Puerto Rico, USA, conducted a study on the sensitivity and selective effect of tungsten oxide nanostructures on pollution gases. The study titled “Effect of Tungsten Oxide Nanostructures on Sensitivity and Selectivity of Pollution Gases” has been published in the journal Sensors on 26 Aug. 2020. The study was carried out by Fenghui et al.

Tungsten (W) is mainly in the W⁺⁶ oxidation state in most W oxides, with six oxygen atoms surrounding each W atom in an octahedral configuration. In oxidized tungsten (WO₃), these octahedra are arranged in a split-angle configuration. In reduced oxides (WO_j, 2 < x < 3), complex combinations of WO₆ octahedra in split-angle, split-edge, and split-face arrangements are frequently found. The WO₄ tetrahedra and WO₇ pentagonal dihedra, which are frequently found in fully oxidized and partially reduced compounds, respectively, add to the complexity of the crystal geography of these compounds.

Molybdenum (Mo) is a refractory metal with a melting point of 2620°C. It hosts a small coefficient of expansion, high electrical conductivity, and good thermal conductivity. It does not react with hydrochloric acid, hydrofluoric acid, and alkaline solutions at room temperature, and is only soluble in nitric acid, aqua regia, or concentrated sulfuric acid. Therefore, Mo and its alloys have a wide range of applications and good prospects. In this article, we will describe 6 uses of Mo.

Recently, researchers from the Danish National Research Centre for the Working Environment clarified the doses of molybdenum (Mo), lithium, and tungsten (W) for inhalation toxicity and evaluated the genotoxicity and carcinogenic potential of these three elements.

Recently, a research team from the Russian Academy of Sciences has successfully prepared tungsten carbide (WC) powder in this study by synthesizing bimodal tungsten powder by electrical explosion of wire (EEW) method and investigated the carburization process of EEW bimodal tungsten powder.

Mo may be a little-known and important element that could be life-threatening when its levels in the body are unbalanced. With 42 protons and 54 neutrons, Mo is located right in the middle of the periodic table, and it is in considerable demand as an alloy for strengthening steel. It's also the only element that keeps most of your food from being lethal.

Recently, a research team from Shanghai Tech University has prepared an electrochromic device (ECD) with a composite niobium tungsten oxide (Nb₁₈W₁₆O₉₃). Their results show that the composite niobium tungsten oxide has a fast response to the applied voltage and no observable degradation of the optical modulation is observed after a long period of cycling. The team's work provides a solution for electrochromic materials with fast response times and good cycling stability.
