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.

A team of researchers from the University of Bath recently published recent research advances on the processing and handling of tungsten (W) and its alloys. It belongs to group 6 of the periodic table, along with molybdenum, chromium, and boron. It is a refractory metal (the highest of all known pure metals) with extraordinary heat and wear resistance. It is known for its high density, high modulus of elasticity, high thermal conductivity, and excellent mechanical properties at high temperatures, in addition to its very high melting temperature. It is an ideal material for high-temperature structures in fusion energy and other applications.

Molybdenum disilicide (MoSi₂), a catalyst that converts carbon dioxide into fuel, has helped researchers take another step toward solving global warming by converting CO₂ into fuel. Using theoretical models, researchers at the Queensland University of Technology's Centre for Materials Science have determined that six metals (nickel, niobium, palladium, rhenium, and rhodium) have been found to be efficient in the reaction that converts CO₂ into sustainable clean energy.

During the cultivation of marijuana crops, if the leaves of the cannabis plants are discolored, there may be a molybdenum deficiency. Molybdenum, a nutrient important to the health of your crops, is a mobile micronutrient that requires only small amounts to function optimally. If your plants don't have enough molybdenum nutrients, they will discolor and become brittle before they die.
