source: Chiba UniversitySamarium (Sm), a rare earth metal, is important to organic chemists because of the ability of its divalent compounds to efficiently perform single-electron transfer reductions.Samarium iodide (SmI2) is moderately stable and can operate under mild conditions at room temperature, making it highly useful for producing pharmaceuticals and biologically active materials. However, most reactions require SmI2 in quantities equal to or greater than the stoichiometric amount and necessitate the use of harmful chemicals, making the process resource-intensive and expensive to manag...

source:Australian National UniversityA mysterious type of iron-rich magma entombed within extinct volcanoes is likely abundant with rare earth elements and could offer a new way to source these in-demand metals, according to new research from The Australian National University (ANU) and the University of the Chinese Academy of Sciences.The research is published in Geochemical Perspectives Letters.Rare earth elements are found in smartphones, flat screen TVs, magnets, and even trains and missiles. They are also vital to the development of electric vehicles and renewable energy technologies such...

source:Joint Institute for Nuclear ResearchScientists of the Laboratory of Neutron Physics at JINR in collaboration with colleagues from the Technical University of Moldova и Horia Hulubei National Institute for R&D in Physics and Nuclear Engineering (Romania) evaluated the accumulation of holmium(III), erbium(III), and gadolinium(III) accumulation by cyanobacteria Arthrospira platensis using neutron activation analysis and elements’ effects on biomass quantity and biochemical composition. The studied elements had different effects on the primary biomolecule content, suggesting that holmiu...
