Phosphate Polymer Nanogel for Selective and Efficient Rare Earth Element Recovery.

Environmental Science and Technology, 2021
Demand for rare earth elements (REEs) is increasing, and REE production from ores is energy-intensive. Recovering REEs from waste streams can provide a more sustainable approach to help meet REE demand but requires materials with high selectivity and ...

Scarcity of Rare Earth Elements

ChemSusChem, 2013
AbstractRare earth elements (REEs) are important for green and a large variety of high‐tech technologies and are, therefore, in high demand. As a result, supply with REEs is likely to be disrupted (the degree of depends on the REE) in the near future. The 17 REEs are divided into heavy and light REEs. Other critical elements besides REEs, identified by

Rare Earth Elements

1987
Intermetallic phases between tungsten and rare earth elements have only been found for the W-Ce system. Two phases exist in this system, which are formed by peritectic reactions; one of them is believed to be W2Ce, “Elliott” (1965), p. 314.

Biosorption of Rare Earth Elements

Mineral Processing and Extractive Metallurgy Review, 1998
Abstract By using X-ray microanalysis, the mechanism of sorption of rare earth elements (REE) and their localization in cells of Candida utilis were found to depend on the metal ion speciation in solution, the permeability of the cytoplasmic membrane (CPM), and elemental composition of cells.

MORB alteration: Rare-earth element/non-rare-earth hygromagmaphile element fractionation

Chemical Geology, 1990
Abstract We have determined the concentrations of rare-earth elements (REE) and non-rare-earth (RE) hygromagmaphile elements (HYG.E): Y, Zr, Nb, Hf, Ta and Th in fresh and altered basaltic samples recovered from the Atlantic Ocean. Whereas the relative abundances of REE and non-RE HYG.E display continuous chondrite-normalized patterns in fresh ...

Rare-Earth Elements in Tektites

Science, 1963
The rare-earth element content of three tektites has been determined by neutron activation analysis. The relative abundance patterns are all nearly alike and are identical to the pattern characteristic of well-differentiated terrestrial sediments. Possible consequences of finding this pattern in truly extraterrestrial matter are considered.

Transition Metal and Rare Earth Element Doped Zinc Oxide Nanowires for Optoelectronics

physica status solidi (b), 2019
Even though intrinsic semiconductor nanowires have already extraordinary optical properties, doping with optically active impurities significantly expands the potpourri of optoelectronic applications, such as for nanowire lasers or single photon emitters.
