An Updated Review of Toxicity Effect of the Rare Earth Elements (REEs) on Aquatic Organisms

Animals, 2020
Simple Summary Rare earth elements (REEs) have become important metals in modern-day technology. The process of discarding obsolete equipment containing REEs, use of REEs containing phosphate fertilizers, mining, and dispersion from indigenous rocks may ...

Spectral Engineering of Slow Light, Cavity Line Narrowing, and Pulse Compression

, 2013
More than 4 orders of magnitude of cavity-linewidth narrowing in a rare-earth-ion-doped crystal cavity, emanating from strong intracavity dispersion caused by off-resonant interaction with dopant ions, is demonstrated.

In vivo molecular imaging for immunotherapy using ultra-bright near-infrared-IIb rare-earth nanoparticles

Nature Biotechnology, 2019
The near-infrared-IIb (NIR-IIb) (1,500–1,700 nm) window is ideal for deep-tissue optical imaging in mammals, but lacks bright and biocompatible probes.

Instability of some divalent rare earth ions and photochromic effect

, 2015
It was shown that the divalent rare earth ions (La, Ce, Gd, Tb, Lu, and Y) in cubic sites in alkaline earth fluorides are unstable with respect to electron autodetachment since its d1(eg) ground state is located in the conduction band which is consistent

Quantum spin fluctuations in the dipolar Heisenberg-like rare earth pyrochlores [PDF]

, 2004
The magnetic pyrochlore oxide materials of general chemical formula R2Ti2O7 and R2Sn2O7 (R = rare earth) display a host of interesting physical behaviours depending on the flavour of rare earth ion.

Critical Rare-Earth Elements Mismatch Global Wind-Power Ambitions

One Earth, 2020
Summary Wind power needs to be expanded rapidly across the world to stabilize our climate. However, there are increasing concerns about conflicts between the supply of rare-earth elements (REs) (mainly neodymium, praseodymium, and dysprosium) and the ...
