High Pressure Stabilizes the Elusive Hexacoordinated Carbon
The MCF6 species (M = Ca, Sr) is more stable than the bicomponent MF2…CF4 mixture in the solid‐state at high pressure (p > 400 GPa). The main building block is the [CF6]2− unit in which carbon is hexacoordinated. Unusually high coordination number for elements has been of great interest in chemistry.

Air‐Sea Gas Exchange in the Coastal Baltic Sea: Implications for Marine Carbon Dioxide Removal
Abstract Air‐sea gas exchange affects the biogeochemical cycling of trace gases such as CO2 and dimethyl sulfide (DMS) on a global scale, thereby influencing Earth's climate. In nearshore regions, differences in wind fetch and surfactants are expected to have an impact on gas transfer velocity (k).
