Triplet‐Triplet Annihilation Enhances Photochemical Curing Contrast for Vat‐Based 3D Printing

open access: yesAdvanced Functional Materials, EarlyView.
Triplet–triplet annihilation photopolymerization (TTAP) resins enhance curing contrast for digital light processing (DLP) 3D printing compared to conventional Type I and II photopolymerizations at matched optical densities. By exploiting a superlinear initiation response, TTAP preserves fine details, allowing reliable fabrication of complex structures ...

Shaping of Biohybrid Functional Living Materials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates a strategy for shaping living mycelium into functional materials by directing its natural growth. Nanoparticles armor hyphae, micron‐scale particles entangle within the network, and printed hydrogel architectures steer expansion, creating defined geometries.

Photon Avalanching Nanoparticles: The Next Generation of Upconverting Nanomaterials?

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective outlines the mechanistic foundations that enable photon‐avalanche (PA) behavior in lanthanide nanomaterials and contrasts them with emerging application spaces and forward‐looking design strategies. By bridging threshold engineering, energy‐transfer dynamics, and materials engineering, we provide a coherent roadmap for advancing the ...

A Printed Zinc‐Ion Microbattery with Extended Shelf Life and Durability for Energy Autonomous Sensors

open access: yesAdvanced Functional Materials, EarlyView.
We present a fully printed aqueous zinc‐ion microbattery (ZnIB) enabled by graphene‐decorated zinc anode and printed MnO@NC cathode using sustainable aqueous‐based ink formulations. The printed 3D electrodes ensure uniform zinc deposition, low overpotential, and long‐term stability.

Engineering Strategies for Stable and Long‐Life Alkaline Zinc‐Based Flow Batteries

open access: yesAdvanced Functional Materials, EarlyView.
Alkaline zinc‐based flow batteries face persistent challenges from unstable zinc deposition, including dendrite growth, passivation, corrosion, and hydrogen evolution, which severely limit cycling stability. Current research addresses these issues through coordinated electrode structuring, electrolyte regulation, and membrane design to control zinc ...
