Irreversible xenon insertion into a small-pore zeolite at moderate pressures and temperatures
Several solutions to the ‘missing xenon’ problem have been proposed that involve the selective sorption of Xe in minerals found in the Earth. It is now shown that a zeolite, Ag-natrolite, absorbs and retains 28 wt% Xe at 1.7 GPa and 250 °C, conditions found in subsurface Earth, through expulsion of metallic Ag(0).

Reactions of xenon with iron and nickel are predicted in the Earth's inner core
Studies of the Earth's atmosphere have shown that more than 90% of xenon is depleted — the so-called missing Xe paradox. Now a theoretical study shows that Xe and Fe/Ni can form inter-metallic compounds of XeFe3 and XeNi3 under conditions found in the Earth's inner core, and could provide a solution to the puzzle.

Anisotropic dysprosium
Beginning with its origins as the archetypal and eponymously elusive rare-earth element, Dante Gatteschi explains why dysprosium and other lanthanides have cornered the market in molecular magnetism.
