Carbon capture with conventional mixed-matrix membranes is limited by the inability to achieve high packing densities of porous fillers while preserving their intrinsic transport properties. Here the authors develop high-performance membranes based on single-crystal covalent organic framework fillers using a weak-interaction inlaying strategy that enables high filler loadings.

Dense iron oxyhydroxide phases may form from an early basal magma ocean, trapping water and potentially contributing to the formation of thermochemical anomalies in the deep mantle, according to high-pressure and high-temperature experiments.
