Comparative Raman scattering studies of GaAs/AlxGa1-xAs and AlxGa1-xAs/AlAs superlattices
, 1999 The room-temperature Raman scattering studies of longitudinal optic phonons in AlAs/AlxGa1-xAs and GaAs/AlxGa1-xAs short-period superlattices with different layer thicknesses were reported. The AlAs LO modes confined in AlAs layers and GaAs-like LO modes

Atomic‐Scale Detection of Néel Vector Switching in the Single‐Layer A‐Type Antiferromagnet Cr2S3‐2D
Advanced Materials, EarlyView.Interfacial electron donation from graphene redistributes charge within single‐layer Cr2S3‐2D, preferentially accumulating at the lower Cr/S plane. The resulting minute magnetic imbalance lifts the equivalence of the two magnetic sublayers, enabling atomic‐resolution identification and field‐induced control of Néel‐vector states in a two‐dimensional A ...

Advanced Materials, EarlyView.A novel W2TiC2Tx MXene prepared through a MAX‐phase route supports sub‐nanometer Co for highly efficient alkaline hydrogen evolution. Strong Co–W interfacial interactions optimize hydrogen adsorption and catalytic activity, enabling low overpotentials of 63 mV at 10 mA cm−2, small Tafel slope of 44.3 mV dec−1, and exceptional durability at industrially

Advanced Materials, EarlyView.For the first time, we shed light on the surface‐to‐bulk diffusion, induction, and reaction behaviors of OH−, H+, and H2O species on model oxides for alkaline hydrogen‐evolving reaction (HER). We first demonstrate that bulk OH− diffusion significantly affects the generation of proton sources and the diffusion/reaction behaviors of protons, thus ...

Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis
Advanced Materials, EarlyView.A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...
