Rare Earth Elements are not found in the ground as independent elements. Rather, they are found in minerals which must be separated chemically in order to obtain them. The minerals containing REE’s are calledR

In 2000, two researchers, Peter Ward and Donald Brownlee, published a book that offered a possible explanation for our species’ apparent aloneness. It is calledRare Earth: Why Complex Life is Uncommon in the Universe(Copernicus Books, 2000). Ward, a paleontologist by training, and Brownlee,...

Rare earth elements (REE) are a group of 17 exotic minerals used to make everything from smartphones and electronic devices, to electric vehicles, wind turbines, and weapons systems. Examples include europium, a material for control rods at nuclear power plants, and gadolinium, used to mak...
In rare-earth doped single crystalline CaFe2As2, the mysterious small volume fraction which superconducts up to 49 K, much higher than the bulk Tc ~ 30s K, has prompted a long search for a hidden variable that could enhance the Tc by more than 30% in iron-based superconductors of the ...
But propelling the green transition will not be that easy. While rare earth elements and critical minerals hold a key to tackling emissions, how they are handled could very well lead Canada down the same path that kicked off the climate crisis.Experts suggestthis...
