The noble gas inventory in CM chondrites represents a mixture of cosmogenic, radiogenic, and abundant primordially trapped noble gases. Jun 22, 2022 ... We used a GE-MIMS to systematically test the applicability of He, Kr, and Xe as artificial groundwater tracers. Snapshots of mean ocean temperature over the last 700 000 years using noble gases in the EPICA Dome C ice core. 14 April 2021. Using the temperature- ... Mar 23, 2024 ... We present a novel approach to form fragile dicationic species, by post-ionization of singly charged ions that are embedded in helium nanodroplets (HNDs). Noble gases are the least reactive of all elements. That's because they have eight valence electrons, which fill their outer energy level. This is the most ... Mar 14, 2022 ... The current Russian invasion of Ukraine, which is disrupting the supply of noble gases that are essential for the manufacture of semiconductor chips.
