Volatilization of Na2O and Its Impact on the Processing of Solid Electrolytes
The volatilization of oxides from ceramics during sintering can have a detrimental impact on their physical properties. As shown in the figure, the release of Na2O from Na3.4Zr2Si2.4P0.6O12 leads to the formation of a ZrO2 surface layer that blocks ionic conductivity.

Designing Porous Boroaluminate Catalysts via Non‐Hydrolytic Ether Elimination
A non‐hydrolytic sol‐gel ether elimination route provides highly porous boroaluminate mixed oxides with homogeneous atomic distribution and acidic active sites. Careful precursor selection results in catalysts that are highly efficient in ethanol dehydration.

Carbonation of MgO‐Nesquehonite Cements
ABSTRACT MgO‐based binders containing hydrated magnesium carbonates are promising low‐carbon materials due to their ability to store CO2 during hardening and carbonation. This study investigates MgO‐nesquehonite (MgCO3ˑ3H2O) binders containing 0, 20 and 40 mass‐% of nesquehonite hydrated in N2‐filled desiccators or at 4 vol‐% CO2, as well as hydration ...

Variability of Saturn's Equatorial Zonal Winds at Cloud Level Between 2018 and 2025
Abstract Saturn's zonal wind profile at cloud level has been measured at different epochs since the Voyager 1 and 2 in 1980–81. At most latitudes, zonal winds change little over time. However, the equatorial region, between planetographic latitudes 10°N and 10°S, presents a complex vertical structure and significant variability.

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...
