The term "Rare Earth" originates from Rare Earth: Why Complex Life Is Uncommon in the Universe (2000), a book by Peter Ward, a geologist and paleontologist, and Donald E. Brownlee, an astronomer and astrobiologist. An alternative viewpoint was argued by Carl Sagan and Frank Drake, among others. It holds that Earth is a typical rocky planet ...

Specific concerns are the acquisition of these elements, especially from foreign sources such as China; how dependence of foreign sources …

The other option is taking into account the price offered by Chinese rare earth makers and putting a ceiling to it, so even if there is a jump in rare earth prices, OEMs do not end up paying ...

The rare-earth glow. After being excited, each rare earth reliably emits precise wavelengths (colors) of light, de Bettencourt-Dias notes. This allows engineers to carefully tune the electromagnetic radiation (light) in many electronics. Terbium, for instance, emits light at a wavelength of about 545 nanometers.

The incompletely filled 4f shell of rare earth ions possesses single electrons and produces the non-zero spin quantum number (S). So the spin angular momentum splits and disturbs the orbital angular momentum (L) in the same space region, resulting in the fine splitting of orbital energy levels, so-called the spin–orbit coupling e ffect.

By Mike Ives • January 28, 2013. In November, the first shipment of raw "rare earth" minerals arrived at an $800 million processing plant on Malaysia's east coast near the home of Tan Bun Teet. The plant, run by Australia's Lynas Corporation, has since begun refining the rare earth metals, essential components in wind turbines, hybrid ...

The most popular rare-earth fund is the VanEck Rare Earth/Strategic Metals ETF, which has an expense ratio of 0.54%, has been around since 2010 and has amassed more than $560...

The Rare Earth Hypothesis is a fairly contentious hypothesis in astronomy. Although it makes several good arguments, many argue that they are too biased towards Earth life. Since Earth life is the only form of life we know of, any assumptions we have about alien life are going to be biased based on what we know. Life on Earth may have …

The rare-earth elements ( REE) are a group of 17 elements on the periodic table, consisting of the lanthanoid series, and scandium and yttrium. While some REEs are not particularly rare in terms of average abundance in the Earth's crust, they are seldom found in concentrations high enough for economic extraction, and global annual production ...

As technology advances, the value of the rare earth metals keeps climbing. These 17 elements from the middle of the periodic table (atomic numbers 21, 39, and 57–71) have prominent uses in manufacturing smartphones, computers, batteries, magnets, and military equipment. While not rare in quantity, they are challenging to produce, …
