Introduction. The lanthanides or "rare earths" have found increasing applications since the 1960s when developments in process technology allowed their purification on a large scale. 1 The rare earths (RE or TREO) have useful materials properties primarily originating from their f -orbital chemistry and oxide stability. 1 These …
By "Earth-like" Chambers meant a rocky planet with water on its surface, orbiting within a star's "habitable zone. " This not-too-hot and not-too-cold inner region, relatively close to the star, supports the presence of liquid water on a planet surface for hundreds of million of years—the time-span probably necessary for the ...
1. Introduction. Rare earth resources are abundant in China and account for over 95% of the world's annual production. Thus, product development and technology would surely take advantage of the rare earth resources, greatly improving the added value of rare resources, especially for high-enrichment rare earth elements like La and Ce. 1 …

The lanthanide elements, or rare earth elements (REEs), are an active research area, with increasing attention directed toward soil and water evaluation and protection. Rare earth element concentrations in surface and groundwaters may be appropriately evaluated by partitioning the REEs into (i) a dissolved fraction (REE3+, …

16 hours agoThin films of rare-earth monopnictide (RE-V) semimetals are expected to turn into semiconductors due to quantum confinement effects (QCE), lifting the overlap between electron pockets at Brillouin zone edges (X) and hole pockets at the zone center (Γ). Instead, using LaSb as an example, we find the emergence of the quantum spin Hall …
REEs are a group of metals comprised of yttrium, fourteen lanthanide elements, and scandium, which have been called 'industrial vitamins' and a 'treasury' of novel materials due to their dominant role in technical progress and in the development of traditional industries. Despite the growing interest, information that has become available …

Alternatively, if the used cellphones contain 300 000 tons of rare-earth material, then that works out to 1.5 kilograms per cellphone. That is also impossible — an entire cellphone weighs much less than 1.5 kilograms, let alone containing 1.5 kg of rare earth materials. Patron points out that these rare earth minerals exist elsewhere outside ...
