source:globalnewsThe new materials are called spinel-type high entropy oxides (HEO). By combining several commonly found metals, such as iron, nickel and lead, researchers were able to design new materials with very finetuned magnetic properties.A team led by assistant professor Alannah Hallas at the University of British Columbia developed and grew the HEO samples in their lab. When they needed a way to study the material more closely, they asked the Canadian Light Source (CLS) at the University of Saskatchewan for help.“During the production process, all the elements will be randomly distrib...

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...
