  • Mn-doped UO2 is a promising nuclear fuel, and is predicted to undergo favourable grain growth during service. This study uses diffraction, spectroscopy and ab initio calculations to study the effect of redox and structure, finding that grain growth may in fact be suppressed.

  • Carbonates are shown to exist in the lower mantle as seen in diamond inclusions, but thermodynamic constraints are poorly understood. Here, the authors synthesise two new iron carbonate compounds and find that self-oxidation-reduction reactions can preserve carbonates in the mantle.

  • The transition metal dichalcogenide IrTe2 is a candidate system to realise topological superconductivity, a sought-after state which could host Majorana fermions, and hence is of interest to the field of quantum computing. Here, the authors combine high-pressure X-ray diffraction and DFT calculations to investigate the evolution in the crystal- and electronic structure of IrTe2 as a function of pressure, highlighting the role of the Te-Ir-Te bond angle.
