Hace 1 día · Their behavior can be manifested through spin-dependent electronic structure and magnetic properties, which rely on the manipulation of spin . Incorporating rare earth (RE) atoms into spinel ferrites has a notable influence on the electronic, chemical, and magnetic properties of a material, as shown by various studies [12,13,14,15,16,17].
Hace 3 días · A table listing the 17 rare-earth elements, their atomic number and symbol, the etymology of their names, and their main uses (see also Applications of lanthanides) is provided here.
Hace 6 horas · The 17 silvery-white rare earth minerals are not uncommon in the earth's crust. But deposits that are economically viable are more difficult to find, and the real rarity comes in the complex ...
Hace 2 días · The thermal and phase stability (ΔT) is analyzed using differential thermal analysis and proves thermal stability is enhanced by doping rare-earth elements (Nd). The amorphous olivine LiFePO 4 phase is identified from X-ray diffraction peaks and it is demonstrated that neodymium carbon modification does not affect the structure of the sample but improves its kinetics in terms of discharge ...
Hace 2 días · Researchers from Trinity College Dublin's School of Natural Sciences have revealed a novel route to the formation of bastnäsite, a crucial mineral for the extraction of rare earth elements (REEs).
Hace 3 días · Electrical properties. The electrical resistivities of the rare-earth metals vary from 25 to 131 microohms-cm (μΩ- cm), which fall into the middle of the electrical resistance values of the metallic elements. Most trivalent rare-earth metals have values at room temperature ranging from about 60 to 90 μΩ-cm.
Hace 1 día · Heteroleptic Rare Earth Tetraalkylphospholide Cyclooctatetraenide Sandwich ... was isolated, [La(C8H8)(µ- PC4Et4)]2 (6). During the course of this study, we report the synthesis and molecular structures of 1Sc and 1Lu, as well as [LuI3(THF)3] (7) for the first time. All complexes were characterised by single crystal X-ray ...
