Advanced Functional Materials, EarlyView.A dual‐binder dry‐processed electrode (DB‐DPE) combining PTFE and PVDF with a nanostructured Al current collector (NSA) forms a mechanically interlocked interface that significantly improves adhesion and reduces interfacial resistance. With an active material content as high as 96 wt.%, the NSA‐based DB‐DPE enables high‐mass‐loading operation (12.5 mAh

Single Solid‐State Ion Channels as Potentiometric Nanosensors
Advanced Functional Materials, EarlyView.Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust
