Anomalous Enhancement in MXene‐Based Electrochemical Actuators: Pseudo‐Capacitance‐Induced Multi‐Charge Accumulation in Confined Space

Advanced Science, EarlyView.
We elucidate the electrochemical actuation mechanism of 2D material‐based electrodes within a MXene‐centered framework, linking atomic‐scale surface chemistry to macroscopic performance (see schematic). Mechanistically, the reduction of Ti─O─Ti sites in H2SO4 triggers the accumulation of hydrated ions at confined active sites, resulting in anomalous ...

Protease‐Triggered Chromogenic Release From Peptide‐Modified Calcium Carbonate Microspheres Enables Colorimetric Detection of Porphyromonas gingivalis Activity

Advanced Science, EarlyView.
We report a chromogenic release‐based assay system with protease‐cleavage peptide‐modified calcium carbonate microspheres for colorimetric detection of Porphyromonas (P.) gingivalis activity. In response to Arg‐specific gingipain secreted by P. gingivalis, the supernatant becomes colored, enabling colorimetric analysis and providing the monitoring of ...

Synergistic NiO‐NiCo Heterostructure Electrode for Highly Active and Durable Hydrogen Evolution in Industrial Alkaline Water Electrolysis

Advanced Science, EarlyView.
This study presents a NiO–NiCo heterostructure electrode that enhances water dissociation and hydrogen adsorption through synergistic interfacial interactions, verified by electrochemical and spectroscopic analyses. Its high performance in a large‐area single‐cell system under dynamic conditions demonstrates how rational non‐precious catalyst design ...
