High/low temperature setups for submillimetric samples under various extreme conditions at the AILES beamline

open access: yesJournal of Synchrotron Radiation, EarlyView.
Two complementary high‐ and low‐temperature experimental setups have been developed at the AILES beamline of Synchrotron SOLEIL to enable infrared and terahertz spectroscopy of submillimetric samples under extreme and well controlled pressure and temperature conditions (from 10 K to 600 K and from vacuum up to 100 GPa).

High‐pressure and high‐temperature polymorphism of Na2CO3 up to 10 GPa

open access: yesActa Crystallographica Section B, EarlyView.
Two new high‐pressure phases, ϵ and ϵ‐II, observed during in situ experiments, complete the high‐pressure phase diagram of Na2CO3 and show that both the incommensurate γ phase and the ϵ phase are stable over a wider pressure–temperature range under mantle‐relevant conditions.We report two new high‐pressure polymorphs of sodium carbonate, ϵ and ϵ‐II ...

Mapping structure–property relationships in a 6‐oxo‐verdazyl radical by variable pressure crystallography and density functional theory

open access: yesActa Crystallographica Section B, EarlyView.
For the first time, the structural response to pressure of a verdazyl radical crystal has been studied. Computational modelling revealed changes in electronic and magnetic properties as a result of a structural phase transition.The response of the 1,5‐tolyl‐3‐phenyl‐6‐oxo‐verdazyl radical (pTolOV) to pressure in the crystalline state has been ...

MIDAS: a methodological framework for high‐speed high‐energy diffraction microscopy data reduction. Part I: methodology

open access: yesActa Crystallographica Section A, EarlyView.
This paper details the complete methodological framework implemented in the MIDAS software for processing high‐energy diffraction microscopy (HEDM) data. We describe the specific algorithms, coordinate systems and physical models used for both far‐field and near‐field HEDM analysis.

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

open access: yesJournal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.
