Cell‐Stress‐Free Percutaneous Bioelectrodes

open access: yesAdvanced Materials, EarlyView.
A structurally adaptive soft microneedle bioelectrode is developed with an effervescent sacrificial core that dissolves after insertion, leaving an ultrathin and highly compliant electrode integrated with skin. This design enables ultra‐flexible, cell‐stress‐free, stable, and high‐fidelity electrophysiological monitoring under dynamic conditions such ...

Heterogenized Copper(II) Phenanthroline Catalysts for Electroreduction of CO2 to C2 Compounds: Substitution on the Ligand Causes Structural Changes to the Molecular Framework and Stability Enhancement

open access: yesAdvanced Materials, EarlyView.
Based on a previously reported binuclear Cu(II) phenanthroline catalyst, a structurally modified version with enhanced stability for electrochemical reduction of CO2 is developed. The second‐generation system allows for stable operation in an MEA electrolyzer with a Faradaic efficiency of >70% for C2 products at elevated current densities.
