Some heavy periodic elements may be created almost exclusively by such cosmic crashes. Europium, one of the least-common elements in the universe, is a candidate and is used in TVs, lasers ...

When cooled and squeezed very hard, the soft metallic element europium turns into a superconductor, allowing electrons to flow unfettered by resistance, a study appearing May 13 in Physical Review ...

It was not until recent years that the metal was isolated. Europium can be found in the ores bastnasite and monazite. The element has also been identified in the sun and some stars. Europium is ...

Europium was the first isolated, high purity rare earth element to enter the public marketplace, in 1967, as a source of the color red in TV sets. There had been color TV before europium ...

When alloyed with other rare earth elements, europium can be used to make permanent magnets, the demand for which has been growing at an exceptional pace owing to their inherent characteristics ...

Learn how rare earth elements drive advancements in renewable energy and other high-tech industries through their unique ...

Europium metal is now known to be highly reactive; the element's most stable oxidation state is +3, but the +2 state also occurs in solid-state compounds and water.

Worse, they generate harmful waste. For instance, extracting europium and terbium—two middle rare earth elements—requires multiple chemical steps. Each step adds cost and pollution.

The result is a system that can selectively transport middle rare earth elements, such as europium (Eu³⁺) and terbium (Tb³⁺), while excluding other ions like potassium, sodium, and calcium. " ...
