Tailored Cationic Visible‐Light‐Active Interfaces for Sustainable, Biodegradable Nanofibers With Dual‐Mode Antimicrobial Activity and Robust Electrostatic Particle Capture

open access: yesAdvanced Materials, EarlyView.
Surface co‐functionalization of biodegradable nanofibers with sodium copper chlorophyllin and quaternary ammonium compounds achieves synergistic antimicrobial activity through combined photodynamic and contact‐killing mechanisms. The cationic surface provides humidity‐resistant electrostatic particle capture while maintaining rapid enzymatic ...

Ferroionic‐Assisted, Charge‐Driven Polymorphic Phase Engineering for Multilevel Memristive Devices

open access: yesAdvanced Materials, EarlyView.
A CuInP2S6/Mo0.92W0.08Te2 heterostructure enables a gradual semiconductor‐to‐semimetal phase transition through Cu+ ion migration and charge accumulation. The spatially engineered 2H/1T′ mixed phases produce continuously tunable conductance states in a two‐terminal geometry, while suppressing depolarizing fields and stabilizing the metastable 1T′ phase.

Understanding Operando Water Management in Hydroxide‐Exchange‐Membrane Fuel Cells

open access: yesAdvanced Materials Interfaces, EarlyView.
Effective water management is vital for high‐performance hydroxide‐exchange‐membrane fuel cells. Using a custom water‐flux station, this study quantifies how membrane thickness, microporous layers, and operating conditions dictate internal water transport.

Life‐Like Ferrous Oxide Microspheres from Kombucha

open access: yesAdvanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Electrospun PCL Fibers Enhanced With Molecularly Imprinted Polymers for the Adsorption of Pharmaceutical Drugs

open access: yesAdvanced Materials Interfaces, EarlyView.
Electrospun polycaprolactone fiber mats embedded with diclofenac‐imprinted polymers were developed to remove persistent pharmaceutical pollutants from water. The materials showed improved adsorption and retention compared to pure polymer mats, with performance influenced by fiber diameter and polymer content.
