Light rare earth elements include the metals ranging from lanthanum to gadolinium on the periodic table of elements, while heavy rare earth metals range from terbium to lutetium. So-called green technologies often depend upon rare earth elements. For instance, Toyota uses an estimated 7,500 tons ...
How Are Rare Earth Elements Used in Manufacturing? These elements find a variety of unique and interesting uses across industry. In fact, many applications rely exclusively on REEs to function. The uses of these materials range from scientific to metallurgical to even decorative. However, the major...

This suggests that our Solar System isn't a typical planetary system, but a relatively rare one. When we look at planets around other stars, we see that planets of a similar mass to Jupiter are found in Earth's spot.这表明，我们的太阳系不是一个典型的行星系，而是一个相对罕见的行星系。
Soils are... Fertile Soils are the primary provider of nutrients and water for much of the plant life on earth. There are 18 elements considered essential for plant growth, most of which are made available to plants through root uptake from soils (Brady & Weil 2007). Soils retain nutrients...
(PMG). PMGs are smaller, lighter, more efficient, and more reliable than equivalent DFIGs, but come with a higher capital cost. Part of this cost is due to the presence of rare earth elements alongside the magnetic steel and copper, including neodymium (Nd), praseodymium (Pr), dysprosium...
Some books are just too difficult to be adapted for technical reasons, although films likeThe Life of Piare changing this idea. CGI (Computer Generated Image) technology has had a huge impact on the film industry. It allowed the previously unfilmable to become a reality. ...
Rare earths refer to a set of17 chemical elements(scandium, yttrium and the fifteen lanthanides). Contrary to what their name seems to indicate, rare earths are no more rare than other more common metals: their concentration in the earth's crust is, for example, higher ...
