Purpose Rare-earth elements (REEs) have been listed as emerging pollutants, and REEs often occur together with heavy metals (HMs) in the environment. Large amounts of REEs and their coexisting HMs enter into the surrounding soils through dust, surface runoff, and leachate, causing serious REE and HM co-contamination and …

During the mid-20th century, rare earth elements were becoming useful in a variety of ways: Cerium, for example, was the basis for a glass-polishing powder and europium lent luminescence to ...
How rare earth elements' hidden properties make modern technology possible. These 17 metals fine-tune light and generate powerful magnetic fields. In August, China finished constructing a maglev ...
Thus, rare earth becomes a non-spontaneous nucleation core, and the grain growth is hindered, thereby refining the grain. (2) Rare earth is a highly active element, which is easy to combine with impurities, such as oxygen and sulfur, to purify the molten pool. The high activity of rare earth can also improve the oxidation resistance of alloys. (3)
To fully domesticate the magnet supply chain, MP Materials also began construction on the United States' first rare earth magnetics factory in April 2022. …

The substitution of rare earth elements indicates that some of the elements Gadolinium (Gd 3+), Samarium (Sm 3+), and Ytterbium (Yb 3+) can be successfully used in dense tissue repair [[13], [14], [15]]. In this work, we report the impact of rare earth element substitution into the matrix of 58S bioglass ceramics for its therapeutic ...
Alloying is an important way to modify biodegradable metal materials. Rare earth elements (REEs) as alloying elements in biodegradable metals have attracted a great deal of attention due to their unique atomic structure and properties. The present review summarizes the effects of rare earth elements on the mechanical properties, …
Application of metal and rare earth nanocomposite materials in the repair of cartilage boxing damage
The implantation of rare earth-based bone repair materials not only promotes the adhesion of osteoblast-related cells but also facilitates the proliferation and …
The rare earth elements (REE) are a set of seventeen metallic elements. These include the fifteen lanthanides on the periodic table plus scandium and yttrium. Rare earth elements …
Here it was found that the pulsed current can improve the plasticity of Mg-13Gd-4Y–2Zn-0.5Zr rare earth magnesium alloy. When the parameters of pulsed current-assisted tension are 200 V; 100 μs; 2 Hz; 0.1 mm/min, the elongation can be increased from 3.6% to 10.4% but without strength loss. By comparing the mechanical properties of the ...

Rare Earth never fully recovered from the split, and despite a short-lived re-formation in the early 80s, Bridges and Rivera were never able to resolve their differences. "Peter Rivera is the reason Rare Earth isn't together today," says Bridges, matter-of-factly. "After the break up in '75 we went to court over the name.
