Probing Electrocatalyst Design for Product Selectivity in CO2 Reduction
Advanced Science, EarlyView.Selective CO2 electroreduction is controlled by catalyst structure, dynamic surface reconstruction, adsorbate interactions, and reaction microenvironment. This review summarizes Cu‐ and non‐Cu‐based catalysts, single‐atom and molecular systems, degradation pathways, and operando/computational strategies for steering CO2RR toward hydrocarbons ...

Sheet‐Size‐Dependent Mosaicity of 2D Phyllosilicate Membranes
Advanced Science, EarlyView.This study explores how the size of 2D vermiculite sheets affects the structure of laminar membranes. High‐resolution x‐ray diffraction reveals how sheet size governs structural disorder and crystallinity. These changes directly impact ion permeability.

Advanced Science, EarlyView.Inspired by biological ion channels, an AB‐staggered β‐ketoenamine‐linked COF enables rapid hydrated‐ion transport through a biomimetic dehydration‐compensation mechanism, where carbonyl‐rich convergent channels partially offset ion dehydration energy. As aqueous Zn battery separators, the COF membranes suppress parasitic reactions and dendrite growth,

Porous Ultralow‐κ sp2‐Bonded Boron Nitride Thin Films as Copper Diffusion Barriers
Advanced Science, EarlyView.Porous sp2‐bonded boron nitride (p‐BN) thin films with an ultralow dielectric constant (κ = 1.77) are directly grown on Si substrates via RF magnetron sputtering. The films feature uniform nanopores (1.85 nm), high mechanical stability, hydrophobicity, and excellent Cu diffusion barrier performance even at 3 nm thickness, offering a promising solution ...
