The effect of rare earth element doping on thermoelectric properties of GeTe

open access: yesChemical Engineering Journal, 2022
GeTe has attracted extensive attention due to high thermoelectric performance. Herein, we comprehensively investigate the effect of rare earth element (Eu, Gd, Er and Tm) substitutions at Ge site of GeTe on its thermoelectric performance.

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

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.

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.

The Rare-Earth Elements

2023
In this section, the elemental forms of rare-earth elements are iron gray to silvery lustrous metals that are typically soft, malleable, ductile, and usually reactive, especially at elevated temperatures or when finely divided. rare-earth elements are examined in terms of physical and chemical properties. This makes them essential components of diverse

Rare-Earth and Transuranic Elements

Physical Review, 1941
Verf. zeigt das starke Absinken der Energie und das Schrumpfen der räumlichen Ausdehnung der \(4f\)- bzw. \(5f\)-Eigenfunktion beim Überschreiten der ungefähren Kernladungszahl \(Z = 57\) bzw. \(Z = 92\). Dieses Vorkommnis bedeutet, daß von diesen Ordnungszahlen ab die \(4f\)- bzw. \(5f\)-Bahnen zu inneren Elektronenbahnen werden.
