Abstract Anodic oxygen evolution reaction (OER) is recognized as kinetic bottleneck in water electrolysis. Transition metal sites with high valence states can accelerate the kinetics to offer highly intrinsic activity, but suffer from thermodynamic formation barrier. Here, we show subtle engineering of oxidized Ni 4+ species surface reconstructed (oxy)hydroxides on multicomponent FeCoCrNi alloy film through interatomically electronic interplay. Our spectroscopic investigations theoretical...

To restrict HER, we report a novel method burying vacancy‐rich @carbonized...

The successful implementation of thin-film composite membranes (TFCM) for challenging solute-solute separations in the pharmaceutical industry requires a fine control over microstructure (size, distribution, and connectivity free-volume elements) thickness selective layer. For example, desalinating antibiotic streams highly interconnected elements right size to block antibiotics but allow passage salt ions water.
