High‐Pressure Synthesis of Quantum‐Stabilised Manganese Superhydride MnH 7

ABSTRACT Through high‐temperature, high‐pressure diamond anvil cell studies combined with in situ synchrotron powder x‐ray diffraction, we investigate the reactivity between manganese and hydrogen up to 182 GPa. Laser heating manganese in an medium at 118 GPa yields body‐centred...

Superconducting Hydride Mg2RhH6 Experimentally Achieved at Lower Pressure

Abstract Although tremendous progress has been made in recent years in the field of polyhydride superconductors, the realization of high critical temperature (Tc) superconductivity still relies on formidable high pressures. Searching for superconducting hydrides at lower pressure...

Genetic links between IIIE iron meteorites and the core of the HED parent asteroid

Rocky planets formed through the differentiation of planetesimals into metal‑rich cores and silicate mantles, yet direct evidence linking these complementary reservoirs remains scarce. Here we show that IIIE irons and howardite-eucrite-diogenite (HED) meteorites are genetically l...

Evidence for heavy iron isotopic enrichment at Earth’s core-mantle boundary

Ocean island basalts exhibit heavier and more variable iron isotopic compositions (δ56Fe) than mid-ocean ridge basalts, but the origin of these signatures remains unresolved. Here we investigate whether Fe-rich ultralow-velocity zones at the core-mantle boundary can provide a dee...
