source:phys.orgCritical Materials Institute researchers at Oak Ridge National Laboratory and Arizona State University have studied the mineral monazite, an important source of rare-earth elements, to enhance methods of recovering critical materials for energy, defense and manufacturing applications.Rare-earth elements occur together naturally in mineral ores such as monazite but are economically challenging to recover. New approaches to separate the valuable ore from unwanted materials are needed.The research team combined theory and experiment to gain atom-level insights on monazite, providin...

source:hurriyetdailynews“As the name suggests, these elements are rarely found around the world,” Dönmez said on Jan. 28 at an event titled “Energy Goals in Century of Türkiye” in Istanbul.“There are 17 rare elements in the periodic table, and we found seven-eight of them in Beylikova [in the Central Anatolian province of Eskişehir]. It is the second greatest discovery in the world.”Rare earth elements will be more important in the future, the minister added.“In the coming period, we will see an unnamed struggle, a war in the field of rare earth elements, just as the energy wars were...

Deep seabed mining plans pit renewable energy demand against ocean life in a largely unexplored frontier source:themandarinAs companies race to expand renewable energy and the batteries to store it, finding sufficient amounts of rare earth metals to build the technology is no easy feat. That’s leading mining companies to take a closer look at a largely unexplored frontier — the deep ocean seabed.A wealth of these metals can be found in manganese nodules that look like cobblestones scattered across wide areas of deep ocean seabed. But the fragile ecosystems deep in the oceans are little un...

source:natureHafnium isn’t a particularly remarkable element. It’s not your explosive sodium, shimmering mercury or stinky sulfur. It’s a greyish metal and is commonly used as a neutron absorber in the control rods of nuclear power plants and nuclear submarines, and as an insulator in computer chips. But hafnium’s discovery, which was reported in Nature a century ago this week1, was of disproportionate importance. The element was identified by two scientists working in Copenhagen: Dutch physicist Dirk Coster and Hungarian chemist Georg von Hevesy. The find secured not only the periodic table’s...
