Rare earth element patterns and Ce anomalies of carbonate rocks. Carbonate REE patterns are less sensitive to meteoric alteration and dolomitization than redox-sensitive elements are; thus, the former can record the local redox conditions in a given area of seawater (Zhao and Zheng, 2014, Liu et al., 2019). The REEs in authigenic …

Apple partner Foxconn to invest $1.5 billion in India. Foxconn plans to invest $1.54 billion in India, the latest in its growing expansion plan, following a surge in revenues in the South Asian market. Foxconn said in a stock exchange filing that the investment will help it fulfil "operational needs." The investment comes two months after the ...

For transition metal–based electrocatalysts, the integration or incorporation with RE elements started with LaNi 5 in the 1970s, and they are developing fast in the 21st century. Not only non-precious metals including Co, Ni, and Fe but also precious metals such as Pt, Au, and Pd realized the incorporation with RE elements to be exploited in …

Transition metals. The transition elements are metals that have a partially filled d subshell (CRC Handbook of Chemistry and Physics) and comprise groups 3 through 12 and the lanthanides and actinides (see below). Post-transition metals. The post-transition elements are Al, Ga, In, Tl, Sn, Pb and Bi. As their name implies, they have some of the ...

One group of natural resources that may prove essential for the next generation of electric motors and turbines are the rare earth elements (REEs)—17 …

The energy transition is an historic pivot from an insatiable thirst for oil to a soaring reliance on minerals. Lithium, cobalt, and the so-called rare-earth elements (or rare earths), among other metals, are essential in the production of most green devices and equipment, including electric vehicles, windmills, and solar panels.

Chemistry in Everyday Life: Uses of Lanthanides in Devices. Lanthanides (elements 57–71) are fairly abundant in the earth's crust, despite their historic characterization as rare earth elements.Thulium, the rarest naturally occurring lanthanoid, is more common in the earth's crust than silver ((4.5 times 10^{−5}~ %) versus (0.79 …
