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.

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 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.

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.
