source:innovationnewsnetworkIntegrating the concepts of Radioactive Waste Management with Life Cycle Analysis towards a circular economy.Radioactive waste is a by-product from nuclear reactors, fuel processing plants, hospitals, and research facilities. It is also generated while decommissioning and dismantling nuclear reactors and other nuclear facilities. Radioactive waste comes from many sources, including nuclear medicine, nuclear research, nuclear power generation, nuclear decommissioning, rare earth mining, and nuclear weapons reprocessing.1,2In France, the classification is done based o...

source:financeIn mid February 2023 Renforth's geologists spent one day on a prospecting effort in the powerline cut corridor at Surimeau, approximately 4km south of the ~20km long Victoria polymetallic battery metals mineralized system, within the Decelles batholith margin. Snow cover was more significant than anticipated and mixed with ice layers. As a result of this only two samples were obtained, one consisting entirely of pegmatite, one of a mix of pegmatite and granite. The samples were both tested with an XRF, which resulted in elevated rare earth element readings. The samples have b...

source:scitechdailyWith strong reducibility and high redox potential, the hydride ion (H-) is a reactive hydrogen species and an energy carrier. Materials that conduct pure H- at ambient conditions will be enablers of advanced clean energy storage and electrochemical conversion technologies.Several H- conductors have already been developed in recent years, but none of the materials could achieve superionic conduction at ambient conditions.The research team targeted the structure and morphology of trihydrides — hydrides containing three atoms of hydrogen per molecule — of certain rare earth ele...

source:physA team of oceanographers at the Scripps Institution of Oceanography, working with a colleague from Chungnam National University and another from the University of Hawaii, has mapped 19,000 previously unknown undersea volcanoes in the world's oceans using radar satellite data. In their paper published in the journal Earth and Space Science, the group describes how they used radar satellite data to measure seawater mounding to find and map undersea volcanoes and explains why it is important that it be done.The ocean floor, like dry land masses, features a wide variety of terrain. ...
