Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

open access: yesAdvanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Active Phase of Nickel Electrocatalysts Driving Alkaline Hydrogen Evolution

open access: yesAdvanced Materials, EarlyView.
Using depth‐resolved and operando spectroscopic measurements coupled with electrochemical mass spectrometry, the authors uncover the critical role of sub‐surface oxidised species in increasing the activity and durability of Ni‐based cathodes for hydrogen evolution.

Measuring and Manipulating Density of States in Two‐Dimensional Materials With Electrochemical Capacitance

open access: yesAdvanced Materials Interfaces, EarlyView.
We report electrochemical quantum capacitance spectroscopy as an ambient, in situ probe for defect‐mediated electronic structure at 2D material interfaces. Using monolayer MoS2, the method resolves band edges and vacancy states, tracks sulfur‐vacancy evolution during hydrogen evolution, and links interfacial density‐of‐states changes to nearly ...

Multifunctional Wound Dressings: Melt Electrowritten Scaffolds Combined With Phytotherapeutic Composite Hydrogels

open access: yesAdvanced Materials Interfaces, EarlyView.
ABSTRACT The increasing prevalence of impaired wounds, caused mainly by diabetes or aging, alongside the growing number of bacterial infections, indicates the need for alternative tissue engineering solutions. In this study, we developed novel melt electrowritten (MEW) polycaprolactone (PCL) scaffolds incorporated with an alginate (Alg)–gelatin (Gel ...
