source:Mining WeeklyThe Queensland government has invested A$1-million into a joint study with the University of Queensland’s Sustainable Minerals Institute to investigated the use of native plants to extract rare earth metals.Through the study, native plants such as selenium weed and a variety of macadamia trees are being researched for their abilities as “hyperaccumulators” that extract rare earth metals from the ground through a process called “phytomining”.Resources Minister Scott Stewart said the innovative world-first joint study has the potential to change how some mines operate in the ...

Size-Dependent Cytotoxicity and Reactive Oxygen Species of Cerium Oxide Nanoparticles in Human Retinal Pigment Epithelia Cells source:DovepressNanomaterials have unique properties, such as small size and enlarged surface area, that enhance regenerative and catalytic enzyme activities and, consequently, their biological effects. Cerium (Ce), a critical rare earth element with a unique f-electron configuration that gives its compounds special properties, has been called a universal new material.1 In cerium oxide nanoparticles (CeO2 NPs), there are two valence states-Ce3+ (reduced state) and...

sorce:SciTechDailyThe Berkeley Lab Laser Accelerator (BELLA) Center at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed and tested an innovative optical system to precisely measure and control the position and pointing angle of high-power laser beams with unprecedented accuracy – without interrupting or disturbing the beams. The new system will help users throughout the sciences get the most out of high-power lasers.The experimental validation effort was led by doctoral candidate Fumika Isono of Berkeley Lab and UC Berkeley. Her findings are describ...
