  • Using in situ high pressure measurements, the structure and density of a sulfide phase with the formula Fe4+xS3 have been determined. The thermal stability of this phase makes it a potential candidate to form a Martian inner core.

  • The charge order transition of commonly known magnetite has only recently been unraveled. Here, the measurement of the low-temperature high-pressure phase diagram of a related material (Fe4O5) elucidates the interplay of average oxidation state and charge-ordering phenomena in the iron oxide family.

  • Through the approach of paracrystallization under high-pressure and high-temperature conditions, exceptional toughening has been achieved in oxide glasses by enhancing their crystal-like medium-range order structure. This discovery offers possibilities for the design of more resilient glass materials.

  • Nanosized chemical heterogeneities modulate andesitic magma viscosity at early stages of nano-crystallization, according to viscosity models that account for variations in transition metal content

  • High pressure experiments may yield materials with unusual combinations of properties, but typically in small amounts and unstable. Here the authors synthesize millimeter-sized samples of metallic, ultraincompressible and very hard rhenium nitride pernitride, recoverable at ambient conditions.
