source:scitechdailyRare earth elements (REEs) are a set of 17 metallic elements that possess similar chemical properties. They earned their name due to their scarce occurrence in the Earth’s crust, typically present in concentrations ranging from 0.5 to 67 parts per million. These elements play a crucial role in modern technology, including products such as LEDs, smartphones, electric motors, wind turbines, hard drives, cameras, magnets, and energy-efficient light bulbs. As a result, the demand for REEs has seen a steady rise over the past few decades and is projected to continue increasing th...

source:miragenewsPhysicists are learning more about the bizarre behavior of “strange metals,” which operate outside the normal rules of electricity.Theoretical physicist Yashar Komijani, an assistant professor at the University of Cincinnati, contributed to an international experiment using a strange metal made from an alloy of ytterbium, a rare earth metal. Physicists in a lab in Hyogo, Japan, fired radioactive gamma rays at the strange metal to observe its unusual electrical behavior.Led by Hisao Kobayashi with the University of Hyogo and RIKEN, the study was published in the journal Science...

source:miningGeoscientists at Trinity College Dublin have developed a cheap and environmentally friendly method for the synthesis of cerium, a rare earth mineral that holds promise for the treatment of diseases associated with inflammation, including cancer.In a paper published in the journal RSC Advances, the researchers explain that they found out why cerianite is associated with REE-carbonates and how exactly it forms in nature. At the same time, they produced a sort of cookbook for material engineers with easy recipes for the synthesis of Ce-carbonates and cerianite with different sizes an...

source:sciencealertFew discoveries in science would revolutionize technology as much as a material that achieves superconductivity at room temperature, under relatively mild pressures.A team of physicists led by Ranga Dias, a physicist from the University of Rochester in New York now claims they might have cracked it, demonstrating a rare earth metal called lutetium combined with hydrogen and nitrogen can conduct electricity without resistance at 21 degrees Celsius (70 degrees Fahrenheit) and around just 10,000 atmospheres of pressure, the team reports.If confirmed by other researchers, this w...
