Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

open access: yesAdvanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Bio‐Responsive Hydrogel for Targeted on‐Demand Release of a Phage Cocktail for Treatment of Pseudomonas aeruginosa Infection

open access: yesAdvanced Functional Materials, EarlyView.
This study presents an injectable hydrogel that responds to Pseudomonas aeruginosa infection by releasing a dual‐phage cocktail on demand. The system degrades selectively in infected wounds, enhances phage localization and stability, and shows potent antibiofilm activity and biocompatibility in an ex vivo human skin model—offering a promising strategy ...

Synergistic Effects of Entropy Tuning in Niobium‐Based Oxide Anode for Fast‐Charging Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
An entropy‐tuned niobium‐based oxide (ETNO) anode for fast‐charging lithium‐ion batteries are presented, engineered via multi‐cation doping. The synergistic effects of entropy tuning result in excellent rate capability and long‐term durability under ultrafast charging conditions.
