2022 Another challenge is that 40% of the critical materials used in an EV – a long list including everything from aluminum to yttrium, a rare earth element –must come from the U.S. or from nations that have a free trade agreement with the U.S. Laurent Belsie, The Christian Science...
The meaning of RARE EARTH ELEMENT is any of a series of metallic elements of which the oxides are classed as rare earths and which include the elements of the lanthanide series and sometimes yttrium and scandium —called also rare earth metal.
Related to rare-earth element:noble metal (râr′ûrth′) n. Any of a group of 17 naturally occurring metallic elements that have similar properties, consisting of scandium, yttrium, and the 15 elements with atomic numbers 57 through 71 (the lanthanides). The rare-earth elements are widely...

When analyzing Rare Earth Elements in mineral samples, one has to deal with several molecular interferences of extremely close masses which cannot be separated using typical high mass resolution conditions. To address such mass interference issues, energy filtering of the secondary ions with a well-...
