Disentangling Polaron Formation Pathways in Y6 by Probing Noninteracting and Interacting Chromophores via Transient Absorption Spectroscopy

Advanced Materials, EarlyView.
The central role of both electronically interacting and noninteracting chromophores in the photogeneration of charges has been unambiguously identified by ultrafast pump‐probe spectroscopy in thin films of the prototypical non‐fullerene acceptor Y6. Onsager‐like autoionization from higher‐energy excitations on Y6 aggregates is found to control polaron ...

Vitamin C‐Induced Photo‐Redox Threshold Enables High‐Fidelity Volumetric Printing of Collagen

Advanced Materials, EarlyView.
Tomographic volumetric printing (TVP) of native proteins is limited by uncontrolled background crosslinking. Here, vitamin C is introduced as a biocompatible redox regulator to establish a tunable nonlinear polymerization threshold response for TVP.

Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced 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.

Investigation of Persistent Luminescence of Strontium Aluminate in Polymer Films for Passive Daytime Radiative Cooling Application

Advanced Materials Interfaces, EarlyView.
Persistent Luminescence of doped SrAl2O4:Eu2+, Dy3+ formulated in polymer matrices is a promising solution to be integrated in building envelopes for enhancing Passive Daytime Radiative Cooling. ABSTRACT Persistent Luminescent (PersL) materials have found applications in several fields; their integration into passive daytime radiative cooling systems ...

Scalable Production of Disordered Nickel‐Iron‐Aluminum Oxides as Stable Anodes for Water Electrolysis: The Role of Aluminum

Advanced Materials Interfaces, EarlyView.
Solution precursor plasma spraying enables the scalable fabrication of porous and disordered nickel‐iron‐aluminum oxide coatings as precious‐metal‐free anodes. Aluminum inhibits crystal growth, optimizes local atomic sites, and enhances charge and ion transport to accelerate reaction kinetics, leading to excellent performance and operational stability.

Interface‐Driven Control of Vanadium Carbide Micro‐ and Nanocrystal Growth During Chemical Vapor Deposition

Advanced Materials Interfaces, EarlyView.
A wrapped copper–vanadium interface enables reliable chemical vapor deposition growth of vanadium carbide micro‐ and nanocrystals. Adjusting methane supply shifts the process from the formation of many small crystals toward lateral expansion and merging of larger domains, while longer growth increases surface coverage without changing the cubic ...
