Hace 1 día · The rare-earth elements (REE), also called the rare-earth metals or rare earths or, in context, rare-earth oxides, and sometimes the lanthanides (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals.
Hace 2 días · May 22, 2024. Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel. This groundbreaking promethium research was led by, from left, Alex Ivanov, Santa ...

Hace 2 días · In a surprising twist, rare earth elements, traditionally sourced from overseas, have been discovered within coal mines in the United States. Recent research has uncovered significant concentrations of rare earth elements (REEs) in active coal mines in the Uinta coal belt of Colorado and Utah. These elements are crucial for the transition to ...
Hace 2 días · Rare earth element studied in solution to advance space exploration tech. Scientists often have to assume promethium’s majority of properties but now they can actually measure some of them.
Hace 3 días · All but two rare earth metals — scandium and yttrium — are part of a chemical group called lanthanides, and light rare earths are the lanthanides with the lowest atomic numbers. The light rare earths are cerium, lanthanum, praseodymium, neodymium, promethium, europium, gadolinium and samarium.
