摘要:Abstract(#br)Inductively coupled plasma-mass spectrometry (ICP-MS) is used to determine rare-earth elements abundances in fluid inclusions. Quartz separates from the Lannigou and Yata Carlin-type gold deposits, southwestern China, were prepared by the decrepitation-leach method. ...

摘要:Rare-earth elements (REEs) are used in a growing number of applications, and their release to environment has increased over the decades. Knowledge of REEs in human milk and factors that could possibly influence their concentration is scarce. This study evaluated the concentrati...

摘要:Abstract(#br)Based on pot-culture experiments, the biological effect of rare-earth elements (REE) on antioxidation enzymes of wheat under acid rain stress was studied. The results show that both acid rain and REE can affect the activity of anti-oxidation enzymes of wheat to diffe...

摘要:... Rare-earth elements have a much lower electronegativity, and can therefore donate electrons easily and fill the antibonding orbital of Pd. Therefore, rare-earth elements are effective in increasing the ORR activity by making Pd more metallic. Moreover, alloying Ir with nobl...

摘要:... Recent researches on oceanic sediments have discovered thin layers (<1 m in thickness) with extraordinarily high concentrations of rare-earth elements and yttrium (REY) in pelagic clay, demonstrating that the bulk chemical compositions of the pelagic clay are more heterogene...

摘要:... In this study, we apply the use of known phosphate solubilising microbes (PSM) to the release of rare-earth elements (REE) from the rare-earth phosphate mineral, monazite. Two sources of monazite were used, a weathered monazite and mineral sand monazite, both from Western...

摘要:Rare-earth elements are used in neodymium magnets, and these elements are critical to Japanese industry. In this study, we focused on the electrochemical behavior of neodymium magnets for the recovery of rare-earth elements using molten salt electrolysis. The influence of the r...

摘要:The distribution and fractionation of rare-earth elements (REE) are studied in the surface and subsurface waters and rocks of the Albynskoe Gold-Bearing Placer. The obtained data show the rocks of the placer to be enriched with rare-earth elements and to feature the predominance ...

摘要:... We use the case study of yttrium, a rare-earth element (REE) on the EU list of CRMs, given its widespread use in the electronics industry and the geopolitical concentration of its supply. Even if recycling REEs from waste electric and electronic equipment is a valid alterna...
