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...

source:phys.orgA researcher in NDSU's Center for Computationally Assisted Science and Technology and the Department of Physics has uncovered what makes a prominent paint glow in the dark for hours. The findings are reported in a paper titled 'Defects and persistent luminescence in Eu-doped SrAl2O4,' published in the journal Physical Review Applied.'The story really began on March 12, 1993, when researchers with Nemoto and Co. Ltd. in Japan successfully developed a new material that re-emits extremely bright green light over many hours in the dark,' said Khang Hoang, the aut...

source:miningIn a recent paper published in the Journal of Biological Chemistry, researchers at ETH Zurich describe the discovery of lanpepsy, a protein which specifically binds lanthanides – or rare earth elements – and discriminates them from other minerals and metals.Because of their similarity to other metal ions, the purification of REE from the environment is cumbersome and economical only in a few locations. Knowing this, the scientists decided to explore biological materials with high binding specificity for lanthanides as mechanisms that could offer a way forward.The first step was to...
