Iron alloys of volatile elements in the deep Earth’s interior

Many volatile elements are depleted in the bulk silicate Earth. Here, the authors found that these volatile elements tend to react with Fe under pressure and may be sequestered within Earth’s core by forming substitutional Fe alloys.

Impact of interannual and multidecadal trends on methane-climate feedbacks and sensitivity

Record-breaking rates of increasing atmospheric methane concentrations in 2020 and 2021 are alarming, but puzzling, in view of declining methane emissions from fossil fuel in 2020. The authors show that interannual variation of both positive and negative feedbacks contribute positively to the rising methane concentration.

Deep carbon cycle constrained by carbonate solubility

Carbonate mineral aqueous solubility decreases as carbonates become more Mg-rich during subduction. Coupled with regional variations in amounts of carbon and water subducted, this explains discrepancies in estimates of carbon recycling, suggesting that only around a third returns to the surface.

Pressure promoted low-temperature melting of metal–organic frameworks

The simultaneous high-pressure and high-temperature phase diagram of two MOFs, ZIF-4 and ZIF-62, is mapped. Crystalline, pressure- and temperature-amorphous, and liquid states are found, while melting temperature is found to decrease with pressure.

Route to high-energy density polymeric nitrogen t-N via He−N compounds

Polymeric nitrogen has yet to be recovered to ambient conditions, precluding its practical application as high-energy density material. Here, the authors highlight a possible route to the formation of a tetragonal polymeric nitrogen via helium-nitrogen compounds at high pressures.

Thick lead-free ferroelectric films with high Curie temperatures through nanocomposite-induced strain

BaTiO₃ can remain ferroelectric at temperatures up to at least 330 °C when it is strained by self-assembled nanoscale columns of SmO.

Structural dynamics of a metal–organic framework induced by CO₂ migration in its non-uniform porous structure

Metal–organic frameworks that undergo structural transitions in response to external stimuli are promising for gas storage, but the mechanisms of such dynamics are poorly understood. Here the authors show that the structural transformation of ZIF-7 is induced by CO₂ migration through its non-uniform porous structure.

Carbon network evolution from dimers to sheets in superconducting ytrrium dicarbide under pressure

Several rare earth carbides are superconducting at ambient pressure and low temperature. Here global structure searching predicts high-pressure metallic phases of yttrium dicarbide with phonon-mediated superconductivity and increased carbon network evolution from dimers to sheets with increasing pressure.

Pressure-induced emission of cesium lead halide perovskite nanocrystals

The potential optoelectronic applications of metal halide perovskites make exploration and tuning of their optical properties of great interest. Here the authors show that non-emitting zero-dimensional cesium lead halide perovskites become strongly fluorescent under high pressure, due to distortion-induced effects.
