Rare-earth hydrides and rare-earth oxides in and from thin films of rare-earth metals

Journal of the Less Common Metals, 1974
Abstract Thin films of rare-earth metals always getter hydrogen very easily under ordinary conditions of preparation. It is shown from X-ray and electron diffraction experiments that the f.c.c. hydrides appear as single-crystal inclusions especially in the case of the yttric series (except for ytterbium).

Rare-earth based nanomaterials and their composites as electrode materials for high performance supercapacitors: a review

, 2020
The emergence of energy crisis and greenhouse effect has prompted people to develop energy storage equipment with excellent performance. Supercapacitors (SCs), also known as electrochemical capacitors, are widely studied for their high power density ...

The Rare Earths

Nature, 1927
IN searching for evidence that would enable a decision to be made as to the exact distribution of the electrons responsible for the series of fifteen rare earth elements from lanthanum to lutecium, the colour of their salts appears to be of prime importance, particularly as it is known that colour is intimately associated with movements of electrons in

The Rare Earth Elements: Demand, Global Resources, and Challenges for Resourcing Future Generations

Natural Resources Research, 2018
The rare earth elements (REE) have attracted much attention in recent years, being viewed as critical metals because of China’s domination of their supply chain. This is despite the fact that REE enrichments are known to exist in a wide range of settings,
